TY - JOUR T1 - Anaerobic degradation of toluene by pure cultures of denitrifying bacteria. AN - 72732002; 1814278 AB - Several denitrifying Pseudomonas spp., isolated with various aromatic compounds, were tested for the ability to degrade toluene in the absence of molecular oxygen. Four out of seven strains were able to degrade toluene in the presence of N2O. More than 50% of the 14C from ring-labelled toluene was released as CO2, and up to 37% was assimilated into cell material. Furthermore it was demonstrated for two strains that they were able to grow on toluene as the sole carbon and energy source in the presence of N2O. Suspensions of cells pregrown on toluene degraded toluene, benzaldehyde or benzoate without a lag phase and without accumulation of intermediates. p-Cresol, p-hydroxybenzylalcohol, p-hydroxybenzaldehyde or p-hydroxybenzoate was degraded much slower or only after distinct lag times. In the presence of fluoroacetate [14C]toluene was transformed to [14C]benzoate, which suggests that anaerobic toluene degradation proceeds through oxidation of the methyl side chain to benzoate.

TBT, dibutyltin (DBT) and monobutyltin (MBT) concentrations in water and whole-body samples were determined by gas chromatography with flame photometric detection. TBT uptake (from a nominal concentration of 8.9 ug per litre) was rapid, but considerably lower in embryos than in yolk-sac larvae. Tissue concentration of TBT in embryos was 0.85 ug per g after 91 h exposure, and in larvae was 4.65 ug per g after total (embryonic and larval) exposure of 164 h. The calculated bioconcentration factor was 107 in embryos after 100 h exposure, and 538 in larvae exposed for 96 h. Elimination of TBT was slow; tissue concentrations in larvae exposed to 4.5 ug per litre for 93 h were 1.59 ug per g, and after 75 h in clean lake water dropped only to 1.48 ug per g. Tissue concentrations of DBT and MBT were low (below 0.3 ug per g) and did not increase with time, suggesting that little or no catabolism of TBT took place.

After 7 d in flow-through conditions, microsomes were prepared from livers of killed fish. Microsomes were incubated at 26C with different concentrations of tributyltin (TBT) in ethanol, and levels of components of the electron transport system were analysed during a 1 h period. In the presence of TBT, total P-450 content decreased in a time- and concentration-dependent manner, accompanied by formation of cytochrome P-420. In 0.2 mM TBT, after 2 minutes, P-450 content had decreased to 50 per cent of its initial level, and no P-450 was detectable after 30 minutes in 1 mM TBT. TBT at 0.3 mM also completely inhibited activity of the cytochrome P-450-associated enzyme, ethoxyresorufin-O-deethylase, after 15 minutes incubation. Cytochrome b5 content and NADPH-cytochrome c reductase activity were unaffected by 0.5 mM TBT, whereas activity of NADH-cytochrome c reductase was doubled.

N1 - Last updated - 2011-12-12 ER - TY - RPRT T1 - DELTA WETLANDS PROJECT, BACON ISLAND AND BOULDIN ISLAND, SAN JOAQUIN COUNTY, AND HOLLAND TRACT AND WEBB TRACT, CONTRA COSTA COUNTY, CALIFORNIA. AN - 36406301; 2929 AB - PURPOSE: Implementation of a wetlands enhancement project is proposed for the Sacramento-San Joaquin Delta and four associated islands in San Joaquin and Contra Costa counties, California. The project would be located on Bacon Island and Bouldin Island in San Joaquin County and the Holland and Webb tracts in Contra Costa County. Generally, the project would involve storage of winter flows of water and development of seasonal wetland waterfowl habitat on the four islands. The water would be pumped from the islands into the delta in the summer for sale for beneficial uses. During the fall, the islands would be managed as waterfowl habitat where private waterfowl hunting would be permitted. To operate its proposed project, the applicant, Delta Wetlands, would divert unregulated delta outflow under appropriative water rights during the period extending from January through April, when water is available for appropriation. Water stored by the project would be discharged from the four delta islands from May through July. Discharged water would mix in the delta pool with delta inflows from the Sacramento and other tributary rivers and would be available as delta outflow or as export water. From August through December, when the island bottoms would be exposed, the islands would be revegetated, either naturally or artificially, with wetland plants of value to wintering waterfowl as forage and cover. From October through December, the islands would be flooded to shallow depths under riparian water rights to attract wintering waterfowl and to support operations of private waterfowl hunting clubs. Sufficient water would be diverted to permit discharge of 270,000 acre-feet of water to the delta for sale. To achieve the proposed water discharge level, approximately 312,000 acre-feet of water would be diverted under the requested appropriative water rights; evaporation from the surface of the stored water would account for the difference between the diverted and discharged amounts. In order to implement this proposal, Delta Water would construct siphons, pumps, and small boat docks on delta channels and use hydraulic fill to buttress perimeter levees and construct interior levees on the islands. The proposal would include provisions for levee protection, seepage control, interior drainage, management of habitat associated with water storage areas, recreational facilities, and management of 900 acres of riparian, wetland, and upland wildlife habitat. POSITIVE IMPACTS: In addition to enhancing the value of the islands as waterfowl habitat, the project would increase the availability of high-quality water and the extent and value of wetland wildlife habitat in the delta. The delta is an important source of water for much of southern California; it is considered one of the state's most valuable suppliers. Hunting and other recreational values of the enhanced islands would improve significantly. The project would provide a model for private sector efforts in the area of wetland enhancement. Levees would provide some flood control benefits. NEGATIVE IMPACTS: Salinity levels could increase in the south delta area and at export locations if reverse flows are caused or enhanced during diversions to storage or during riparian diversions to seasonal wetlands. Trihalomethane precursors, organic concentrations, and algal concentrations could be increased in export water. Stored water could be contaminated by historic waste disposal sites on the islands. Surface waters could be contaminated by domestic wastes from the proposed hunting club facilities. Seepage and wind erosion from levees could create flood hazards, affecting utilities and State Route 12. Delta smelt larvae and juveniles could be entrained. Approximately 248 acres of riparian woodland and 224 acres of perennial freshwater marsh would be inundated. Annual watergrass in seasonal wetlands and special-status plant populations along perimeter levees could be lost. Wintering habitat for swans and geese would be reduced, and prime agricultural land would be converted to nonagricultural uses, reducing farm jobs.

AN - 36406150; 2926 AB - PURPOSE: Designation of a dredged material disposal site off the mouth of the Atchafalaya River and adjacent to the Atchafalaya Bar Channel off the coast of Louisiana is proposed to provide a permanent site for disposal of material dredged to maintain the bar channel. This draft supplement to the draft environmental impact statement (DEIS) of November 1983 addresses revisions made in the proposal since the DEIS. The boundaries of the proposed site are approximately the same as the interim designated site except that the proposed site has been shifted slightly to the east and the length of the proposed site has been extended on the northern and southern ends. The boundary coordinates of the proposed site are 29 degrees, 21 minutes, 24.92 seconds north latitude (N), 91 degrees, 23 minutes, 11 seconds west longitude (W); 29 degrees, 21 minutes, 8.86 seconds N, 91 degrees, 22 minutes, 47.47 seconds W; 29 degrees, 7 minutes, 59.43 seconds N, 91 degrees, 34 minutes, 27.51 seconds W; and 29 degrees, 8 minutes, 15.46 seconds N, 91 degrees, 34 minutes, 51.02 seconds W. The boundaries of the proposed site were lengthened, relative to the interim site, to accommodate actual and potential increases in the oceanward bar channel limit requiring maintenance. The proposed site is 30.8 kilometers (19.13 miles) long and 0.8 kilometers (0.5 mile) wide. The center of the site is approximately 26 kilometers (16 miles) from the mainland coast. The site has an average depth of approximately five meters (16 feet) and a total area of 2,480 hectares (9.57 square miles). POSITIVE IMPACTS: Provision of an environmentally and economically acceptable location for disposal of dredged material would ensure maintenance of navigational access to harbors along the Atchafalaya River, while preventing undue damage to the coastal environment of Louisiana. NEGATIVE IMPACTS: Disposal operations would smother benthic organisms and could result in the formation of a mound at the site. Operations would also result in short-term turbidity and associated lowering of water quality. Adverse impacts on migrating nekton and short-term interferences with commercial or recreational fishing could occur during disposal dredging.

Preparation date: December 20, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED SUNRISE DOUGLAS GENERAL PLAN AMENDMENT, SACRAMENTO COUNTY, CALIFORNIA. AN - 36401740; 2921 AB - PURPOSE: Rezoning 1,225 acres of land from agricultural to urban uses and filling of 50 acres of seasonal drainages and vernal pools are proposed in Sacramento County, California. The project site, referred to as the Sunrise Douglas site, occupies a 2.5-mile stretch along the east side of Sunrise Boulevard between Douglas Road and Kiefer Boulevard, adjacent to and east of Mather Air Force Base (AFB). Zoning for the site would provide for development. Under the proposed project, 7,111 residential units would be constructed on 842.6 acres of land, while 42.5 acres would be dedicated to commercial use, 36.9 acres to industrial use, and 303.5 acres to open space. Activities pursuant to the rezoning plan would include major water system improvements, an amendment to the sphere of influence boundary to provide wastewater service to the site, construction of a new wastewater interceptor, financing of approximately four schools in the Elk Grove Unified School District, and modification of the Sacramento Regional Transit District boundaries. The impacts mitigation plan that would be implemented in association with the rezoning and development of the tract would include provisions for erosion and sediment control, runoff detention, landscaping, use of vegetated swales to convey drainage, and steam buffers. Other mitigation measures would be provided to deal with hazardous wastes, climate and air quality, noise abatement, biological resources, land uses and aesthetics, public services and facilities, and transportation services management. POSITIVE IMPACTS: In addition to providing additional affordable housing and associated industrial and commercial employment opportunities in the Sacramento area, development of the tract would be consistent with the county of Sacramento General Plan as well as other building goals developed by the county. Residential use of the site would result in fewer traffic impacts than would residential development at other available sites. The project would allow for densities adequate to support mass transit facilities. NEGATIVE IMPACTS: Wetlands within the site would change from natural to artificial in character. Approximately 50.8 acres of wetlands, including 320 vernal pools covering 35.4 acres, 9.2 acres of wetland swales, 2.4 acres of intermittent streams, and 3.8 acres of artificial ponds, would be filled. Approximately 922 acres of open space would be displaced, and ambient air quality would decline due to emissions from developed uses. Eleven special status plant populations would be lost, and an American badger den would be eliminated. Developments at the site would generate traffic that would contribute to congestion along the Highway 50 corridor. The influx of population into the rezoned, developed area would require substantial commitment in providing public services and infrastructure to support residential, commercial, and industrial uses. The growth pattern in the area would undergo a substantial change from agricultural to urban uses. The growth pattern would have no logical artificial or natural boundary and, hence, would be likely to proceed to the county border. Odors from the Sacramento Rendering Company would affect future residents, and the company would generally conflict with residential uses at the site. Noise generated by the operation of B-52s at nearby Mather AFB would also be incompatible with residential uses. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: December 14, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SANTA ROSA SUBREGIONAL WATER RECLAMATION SYSTEM, SONOMA COUNTY, CALIFORNIA: LONG-TERM WASTEWATER SYSTEM. AN - 36401515; 2934 AB - PURPOSE: Implementation of a subregional water reclamation system for the city of Santa Rosa, Sonoma County, California is proposed. The city operates a subregional wastewater treatment, reclamation, and reuse disposal system that serves the cities of Santa Rosa, Rohnert Park, Cotati, and Sebastopol, and the South Park Sanitation District, as well as 70 percent of the septic tanks serviced in Sonoma County. Wastewater is treated and reclaimed through tertiary wastewater treatment, including filtration. During the winter, treated water is stored for discharge to the Russian River via the Laguna de Santa Rosa. During the summer (May 15 through October 1), discharge to the Laguna de Santa Rosa is prohibited; during these months, wastewater is reused for irrigation purposes. Approximately 40 to 50 percent of treated water is used for irrigation. Winter discharges to the Laguna de Santa Rosa are only allowed after the river flow has reached 1,000 cubic feet per second as measured at Hacienda Bridge in Guerneville and, then, at rates that do not exceed one percent of the river flow. Hence, the successful operation of the existing system depends on the weather. Under the currently proposed plan, reclaimed water would continue to be used to irrigate approximately 4,500 acres of land in the Laguna de Santa Rosa watershed and to irrigate at least 7,500 acres of currently unirrigated lands in the Americano Creek and Stemple Creek watersheds. Reclaimed water would also be used to create wetlands and vegetated riparian corridors in the Laguna de Santa Rosa and Americano Creek watersheds and to restore aquatic habitat, including resident trout and anadromous fisheries, in Americano Creek. Approximately 70 percent of Santa Rosa's wastewater would be reused for irrigation, while the remaining 30 percent would be reused for wetland creation and stream enhancement or discharged to the Russian River in accordance with regulatory requirements contained in the North Coast Water Quality Control Plan. Facilities needed to implement this proposal would include a five-mile pipeline from the Laguna Subregional Wastewater Treatment Plant to a 5.0-billion-gallon (15,000-acre-foot) storage reservoir in the Two Rock-Bloomfield-Valley Ford area of west Sonoma County. The reservoir would have a surface area of 250 acres. An irrigation water delivery system would supply water to 7,500 acres of currently unirrigated land, and more than 500 acres of wetlands would be created or enhanced. In addition, the Laguna wastewater treatment plant would be expanded from a capacity of 18 million gallons per day (MGD) to 25 MGD. Other alternatives under consideration include: (1) continuation of the existing system; (2) development of a scheme similar to that of the proposed alternative, except that excess treated wastewater would be delivered to irrigate approximately 4,300 acres of farmlands in the Lakeville area and to create wetlands adjacent to the Petalume River and San Pablo Bay; (3) discharge of excess treated wastewater via a 1.5-mile ocean outfall extending from the shore near the mouth of Salmon Creek; and (4) continuation of the existing system with the treatment level improved beyond the current tertiary level and discharging larger volumes of water into the Russian River. Alternative (2) would require construction of a 25-mile pipeline and nine reservoirs to provide for 5.0 billion gallons of storage. POSITIVE IMPACTS: Providing means of storing, using, and/or disposing excess treated wastewater flows during low flows on the Russian River would allow the system to meet water quality requirements for the river. In addition, reuse of excess flows would provide for irrigation needs, enhance stream flows, and create and enhance wetlands in the area. The wastewater disposal requirements of the subregion would be met. NEGATIVE IMPACTS: The proposed alternative would displace 20 acres of wetlands at the reservoir site and some grassland and associated wildlife habitat would be lost. The existence of a reclaimed water storage reservoir and the irrigation of presently unirrigated lands could affect groundwater levels and quality in certain areas. Alternative (2) would result in a loss of 214 acres of wetlands and 12 acres of riparian habitat at the nine reservoir sites. Construction of a pipeline through Bodega Bay under Alternative (3) would disrupt traffic within the area and generally disrupt the community. Continuation of the existing system, under Alternative (1), would result in significant impacts to subregional water quality.

Preparation date: December 12, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STATE TRUNK HIGHWAY 67, OCONOMOWOC 67 BYPASS (SUMMIT AVENUE-LANG ROAD), WAUKESHA COUNTY, WISCONSIN. AN - 36384942; 2920 AB - PURPOSE: Improvement of 4.57 to 4.91 miles of State Trunk Highway (STH) 67 in Waukesha County, Wisconsin is proposed. Three bypass alternatives (2, 2A, and 2B) are under detailed consideration. The basic bypass alternative would provide a bypass of Oconomowoc. The south leg, between Summit Avenue and Wisconsin Avenue, would consist of a depressed, four-lane, divided urban roadway constructed on rights-of-way acquired in the 1970s. The roadway cross-section would consist of two 12-foot driving lanes in each direction, separated by a narrow median. A bridge would span the Soo Line Railroad, a frontage road, Plank Road, and STH 16. An interchange would be located just north of STH 16, with signalized access. At-grade intersections would be provided at Summit Avenue, Old Tower Road, and Armour Road. The north leg of Alternative 2 would begin at Wisconsin Avenue, proceed north across Lisbon Road, County Trunk Highway (CTH) Z, and CTH K, and swing westerly to rejoin existing STH 67 near Lang Road. The cross-section would consist of two 12-foot lanes in each direction, separated by a 60-foot grass median, with 10-foot outer shoulders. Bridges would be constructed over the Oconomowoc River and Rosenow Creek. Intersections at Lisbon Road and CTH Z would be at-grade, and the CTH K crossing would be grade-separated. Two four-lane pavements would eventually be constructed between STH 16 and CTH Z. Two subalternative bypass alignments are also under consideration within Alternative 2. Alternative 2A, which was developed in response to public concerns regarding farmland severances and crossings of spring areas, would be coterminus with Alternative 2 between Wisconsin Avenue and CTH Z, after which it would curve west across the Oconomowoc School District property. Under Alternative 2A, the CTH K crossing would be grade-separated. Alternative 2B, which was developed as a result of additional public and agency input regarding potential impacts to the Rosenow Creek fishery, severance of a nature study area on the school district property, and impacts to relatively undisturbed wildlife habitat adjacent to the school property, would be the same as Alternative 2 between Wisconsin Avenue and Lisbon Road. From Lisbon Road, Alternative 2B would swing east to cross Rosenow Creek approximately 900 feet west of Alternative 2; due to the topography at CTH K, a grade-separated crossing would carry the STH 67 bypass over CTH K. Estimated costs of alternatives 2, 2A, and 2B are $10.5 million, $11.1 million, and $11.2 million, respectively. POSITIVE IMPACTS: Access to several local communities within Waukesha, including the city of Oconomowoc, as well as access to Interstate 94 would be improved substantially. Future increases in average daily traffic levels, which are projected to increase by 40 percent in the Oconomowoc area by the year 2012, would be accommodated by expanding highway capacity as proposed. NEGATIVE IMPACTS: Acquisition of 111 to 120 acres of new rights-of-way would require displacement of seven residential buildings, 88 to 111 acres of farmlands, 9.8 to 14.5 acres of wetlands, and 9.4 to 14 acres of woodlands. Eight to 10 farming operations would be affected. Two to three waterways would be crossed; regardless of the alternative chosen, the Oconomowoc River and Rosenow Creek would be crossed.

Preparation date: December 12, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED SAINT HERMAN SMALL BOAT HARBOR PROJECT, KODIAK, ALASKA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF 1976). AN - 36401455; 2928 AB - PURPOSE: The improvement of Saint Herman Harbor facilities on Kodiak Island, Alaska, is proposed. Kodiak is a fishing and transshipment community located approximately 250 miles southwest of Anchorage. The need for additional moorage for the fishing fleet resulted in a study that culminated in a 1976 final environmental impact statement (EIS) and feasibility report covering the improvement project. The project received congressional funding approval in 1986. The authorized project plan was reevaluated, along with two other structural alternatives and a No Action Alternative. New geotechnical information and new findings associated with dredging and disposal resulted in alteration of the 1976 plan. This supplement to the final environmental impact statement of 1976 proposes a new plan based on findings of studies conducted subsequent to the 1976 proposal. The most significant action in the currently proposed plan would involve construction of a rubblemound breakwater between Near Island and Gull Island, with a gap in the structure adjacent to Near Island. The ends of the breakwater at the gap would be offset to minimize wave action in the direction of the inner harbor. The gap could be located anywhere between Near Island and Grass Island, but the wave climate is lowest adjacent to Near Island, indicating that the gap should be located at that end of the structure. The two-section breakwater would extend 1,865 feet, and the gap would be 200 feet long. The north entrance channel would be widened and deepened. A short breakwater would be constructed on the southwest side of this channel to protect the channel and associated mooring facilities from locally generated waves. The mooring basin would cover 90 acres. Nonfederal facilities would include mooring floats located in the Gull-Uski cove, with additional mooring floats extending from Near Island. A bridge could be constructed across the channel between Near Island and Uski Island, with a road extending along the north side of Uski Island to Gull Island. POSITIVE IMPACTS: By improving the existing condition of the Saint Herman Harbor breakwater, long-period ocean swells, which currently roll under the existing floating breakwater causing vessel and facility damage within the harbor, would be remedied. Congestion and the need for hot-berthing and rafting practices would cease due to expansion of the harbor capacity. NEGATIVE IMPACTS: Approximately 0.6 acre of intertidal habitat would be lost due to fill and excavation, and 10 acres of subtidal habitat would be displaced by the breakwater and its pad. Degradation of local water quality, due to harbor operations and decreases in tidal circulation caused by the solid breakwater, could impact juvenile salmonids. A colony of seabirds on Gull Island could be disturbed during construction.

AN - 36401555; 2902 AB - PURPOSE: Improvement of interchanges connecting Interstate 25 (I-25) with 49th and 58th avenues in Denver and Adams counties, Colorado is proposed. The project has seven major components: (1) closing the I-25/49th Avenue interchange; (2) constructing a new I-25 southbound off-ramp to 48th Avenue as partial replacement access for closing the I-25/49th Avenue interchange and not replacing the southbound on-ramp and northbound on- or off-ramps; (3) reconstructing the I-25/58th Avenue interchange, including the widening of 58th Avenue between Broadway and new Logan Court, shifting the centerline of I-25 approximately 60 feet to the east at 58th Avenue, and adding a continuous acceleration and deceleration lane on northbound and southbound I-25; (4) constructing new Logan Court between 56th and 58th avenues, including a new signalized intersection, and reconstructing the main entrance to the Denver Merchandise Mart at 58th Avenue and new Logan Court; (5) removing the traffic signal at 58th Avenue/Logan Street and restricting turning movements to right-in-right-out (except for a left to Logan Street north of 58th Avenue); (6) upgrading the west frontage road (Bannock/Broadway) between 48th and 60th avenues, including improvements to 48th Avenue between Bannock and Broadway; and (7) changing the east frontage roads (Lincoln, Broadway, and Acoma streets), including the closing of Lincoln Street between 56th and 57th avenues. Costs of the project are estimated at $21 million for construction and $3 million for rights-of-way acquisition. POSITIVE IMPACTS: The safety and capacity of the affected I-25 interchanges would be improved. Removal of the 49th Avenue interchange would eliminate conflicts with the I-25/I-70 interchange immediately to the south; the latter interchange is scheduled for reconstruction to improve its safety and capacity. Removal of the 49th Avenue interchange and replacement of the 58th Avenue interchange would also allow for the provision of high-occupancy vehicle lanes on I-25. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of two residences, three businesses, and one public facility. Landscaped areas and business parking areas would be affected along the west and east frontage roads and along 58th Avenue between Broadway and new Logan Court. Some wetlands would be lost. Redistributing traffic affected by the closure of the 49th Avenue interchange to other interchanges along I-25 and I-70 would increase traffic on some residential streets in the Globeville neighborhood. Travel distances and time for out-of-direction traffic accustomed to using the 49th Avenue interchange would increase significantly. The area affected by the turning restrictions at 58th Avenue and Logan Street would also experience an increase in out-of-direction travel distances and time. Access to some businesses and homes near the existing 49th Avenue interchange and at 58th Avenue and Logan Street would be less convenient. Noise levels affecting some sensitive receptors would increase throughout the project areas. Properties containing hazardous wastes may be encountered.

AN - 36401080; 2944 AB - PURPOSE: Construction and operation of Elk Creek Lake, a component of the Rogue River Project, in Jackson County, Oregon are proposed. The lake would be situated on Elk Creek behind a concrete dam 1.7 miles upstream of its confluence with the Rogue River. This second draft supplement to the final environmental impact statement (EIS) of September 1971 has been prepared in response to the decisions of the Federal Ninth Circuit Court of Appeals, the U.S. Supreme Court, and the U.S. District Court for the District of Oregon in Oregon Natural Resources Council v. Marsh; the decision indicated that the final EIS and first EIS supplement did not comply with the requirements of the National Environmental Policy Act. The 249-foot-high, 2,580-foot-long concrete dam would impound 101,000 acre-feet of water at full pond, 41,000 acre-feet at minimum control pool, and 6,000 acre-feet at minimum conservation pool. The project would require acquisition of 3,502 acres of land. Costs to complete the project, with and without a conservation pool, are estimated at $69.0 million and $72.0 million, respectively, and annual operation and maintenance costs are estimated at $500,000. The issues identified by the courts and stressed in this document are effects on flows, water temperature, and turbidity and related effects on fish production and fishing in the Rogue River; effects on recreation and the local economy; and effects on wildlife and wildlife habitat mitigation. POSITIVE IMPACTS: The project would protect downstream areas from flooding. Dam operation would provide 20,000 acre-feet of water for downstream municipal uses and 88,000 acre-feet for irrigation. On completion, the lake fishery and associated land would attract 290,000 additional visitors per year within 20 years and enhance fish and wildlife management in the region. NEGATIVE IMPACTS: The impoundment would inundate 6.2 miles of Elk Creek, eliminating self-sustaining populations of summer and winter steelhead and coho salmon; increase turbidity duration in the creek; inundate 1,290 acres of land, destroying vegetation and farm and forest land and displacing wildlife habitat; and destroy some wetlands.

The stochastic nature of the model results from postulating a probabilistic model for parameter estimation and input errors. The key factors assumed to contribute to prediction uncertainty are errors in estimating infiltration parameters and moisture conditions prior to a rainfall event. The error distributions for parameter estimates are inferred from soil survey information, and the error distribution for moisture conditions from a regression between antecendent precipitation indices and measured soil moisture. Comparison of model predicted and observed errors demonstrate that the model is conservative in that it is biased towards over-prediction of errors. JF - Technical Papers.

Reallocation of storage capacity between purposes and other modifications in the operation of existing reservoirs is an ongoing consideration to meet future water supply needs. Conversion of storage capacity from water quality, hydroelectric power, or flood control to municipal and industrial water supply is of particular interest. Recent drought conditions experienced over large sections of the nation have focused attention on optimizing the effectiveness of single reservoirs and reservoir systems for meeting project purposes.

Using a non-destructive, acoustic technique known as Ultrasonic Pulse-Echo or UPE, the equipment introduces ultrasonic stress waves into concrete electronically. Signal generation and detection is accomplished with piezoelectric crystals. The diagnostic capacity of this device represents a significant breakthrough for evaluating a difficult non-homogeneous composite material such as concrete. UPE is routinely used for metals testing, underwater detection and ranging (sonar), medical diagnosis, and testing and evaluating homogeneous and fine-grained materials. UPE is nondestructive and can be used in the dry or under water. Significant savings are gained by eliminating the bulk of coring that normally is needed for evaluation of concrete. UPE evaluation allows a precise mapping of regions of quality concrete and regions that have deterioration. Since faulty zones can be pinpointed, repairs will be less expensive. An important feature of UPE is the ability to monitor the condition of a structure over time. The first set of measurements (original construction and restored areas) serves as baseline data that can be compared with later measurements. The baseline data is stored on magnetic disc and can be retrieved and plotted either over or adjacent to the new signals for comparison purposes. However, considerable engineering judgment is needed to properly evaluate a measurement. Presently the system is limited to penetration depths of 1 foot.

Capping of contaminated material in open-water sites began in the late 1970s, and a number of capping operations under diverse disposal conditions have been accomplished. Case studies of actual capped disposal projects are useful in determining the effectiveness of the procedures used and for planning subsequent projects. The New England Division (NED) of the Army Corps of Engineers is conducting a demonstration of controlled placement techniques at the Massachusetts Bay Disposal Site (MBDS), formerly the Foul Area Disposal Site, located approximately 22 nautical miles east-northeast of Boston in a water depth of 90 m. The study will determine the areal extent and thickness of the dredged material deposit formed at the MBDS as a result of the controlled placement. A disposal mound with a radius of approximately 250 m is expected to be created with a 10-m radius of release at the surface. The ability to create a mounded deposit for this project will greatly increase confidence in the ability to successfully execute capping projects at the MBDS site. The US Army Engineer District, Seattle and the Municipality of Metropolitan Seattle (METRO) are cooperating in a demonstration capping project for contaminated sediments adjacent to the Denny Way Combined Sewer Overflow (CSO). The Denny Way demonstration will involve the placement of a sand cap over the contaminated sediments. A 0.9-m cap is planned. METRO will perform future testing of cap effectiveness. The study will demonstrate the feasibility of using this approach and will provide information on material placement rates, operational logistics and problems, and cap coverage obtained for the project. The information gained in these two demonstration projects will be used in developing Corps guidelines for capping under a wide variety of conditions.

Automated inspection tools, referred to as 'silent inspectors,' are one way to assist inspectors, reduce the cost of responding to claims and make dredge production records more accessible, understandable, and usable. An effective automated dredge monitoring system can provide unbiased information to all parties involved in dredging activities. The removal and placement of dredged material, especially contaminated sediments, is a politically sensitive issue. Collecting accurate, unbiased information during dredging operations is becoming increasingly important in verifying compliance with project plans. The DOSIS (Dredge Operations Silent Inspector System) was developed as a data acquisition, communications, analysis, and reporting system to assist in the inspection of contract dredging operations. The final design will consist of a set of standards, functional descriptions, and software. The focus of the design effort is to define the physical methods and logical formats needed to specify the interfaces. Data from sensors give the dredge position and the state of the dredge in the dredging cycle. The physical and logical methods for connecting to the sensors must be carefully defined to meet the system requirements. Factory automation and process control industry connection methods are probably suitable for the dredging environment. After dredge data are transferred from the dredge to the field office, the local office computer generates summary reports. The dredge analysis system will use relational database software instead of conventional programming to generate reports. Not only can the standard reports be produced, but also custom ad-hoc reports can be generated by simply varying the queries to the database. DOSIS will also display the data in graphic form, such as plots of time histories of recorded parameters. Dredge position and other important data can be exported in a form that is compatible with Corps computers used for Geographic Information System (GIS) applications. The GIS could contain project survey data and important information such as project boundaries and disposal site locations. After the system design phase is completed, construction, deployment, and testing of a prototype system will be conducted.

Dredging is also a way to obtain sand which is used for construction purposes and to restore beaches damaged by storms, tides, and erosion. There is no single alternative that can handle all dredged material from the Harbor for more than a few years. Ocean dumping has been found to be the only alternative that is both economically feasible and environmentally safe for large volumes of clean material. Since 1914, most of the dredged material generated has been disposed in the ocean at the Mud Dump Site, 6 miles east of Sandy Hook, New Jersey, carefully monitored by the US Army Corps of Engineers. For material than cannot be ocean disposed without capping, borrow pits, underwater sand and gravel pits left in the harbor after sand mining has been completed which can subsequently be filled with muddy sediment and then capped, seem the most likely alternative that could be implemented relatively quickly. Containment islands, confined facilities in the water within diked areas, should be seriously considered as a long-term alternative. Land disposal, particularly when combined with sanitary landfill cover, will be used in special cases, such as for high levels of contamination.

AN - 36401964; 2930 AB - PURPOSE: Implementation of a water resources management program in the north Delta area of southern California is proposed. The north Delta area includes the islands and channels south of Sacramento, north of the San Joaquin River, east of Rio Vista, and west of Thornton. The area encompasses 170,000 acres, of which 150,000 are used for irrigated agriculture; the remaining 20,000 acres consist of waterways, natural areas, levees, and lands devoted to residential, industrial, and municipal uses. The Sacramento River, Mokelumne River, Cosumnes River, Dry Creek, Morrison Creek, and Deer Creek converge in the area in a network of meandering channels and sloughs. The most pressing problem in the study area is repeated and extensive flooding of the leveed tracts and islands. Two types of alternatives were reviewed to deal with area management needs, specifically, North Delta Program alternatives and water supply augmentation and demand-reduction alternatives. The preferred alternative would involve dredging the main stem and South Fork Mokelumne River, enlarging the main stem and North Fork Mokelumne River with levee setbacks and channel dredging, enlarging the Delta Cross Channel gate structure, acquiring necessary state and federal permits, and testing mitigation measures, including collector wells and fish screens. The estimated cost of the preferred alternative is $290.0 million. POSITIVE IMPACTS: Program implementation would relieve flooding in the north Delta, including flooding of the towns of Thornton and Walnut Grove, reduce reverse flow in the lower San Joaquin, improve water quality, reduce fishery impacts, and improve State Water Project flexibility and water supply. In addition to meeting these primary objectives, the program would improve navigation, enhance recreational opportunities, and enhance wildlife habitat. Annual benefits redounding from the program would be worth $49.6 million. NEGATIVE IMPACTS: Some impacts to resident fish, including game fish, would be expected. Some operational changes would decrease Delta outflow during controlled flow conditions, having a minor impact on the environment. Increases in cross-delta flow would impact salmon smolts and striped bass eggs and larvae due to diversions from the Sacramento River. Approximately 1,040 acres of farmland would be displaced by levees, berms, and channels. Decreased flow velocities in the north and south forks of the Mokelumne River could cause sedimentation.

AN - 36405552; 2945 AB - PURPOSE: Implementation of flood control measures in the upper basin of the Rio Grande de Loiza of Puerto Rico is proposed. The upper Rio Grande de Loiza basin drains an area of approximately 530 square kilometers (km) into Lake Loiza. Heavy rainfall combines with very steep slopes to produce high discharges in a relatively short period of time. Flooding in the study area affects more than 4,675 families and numerous public buildings and facilities. The recommended plan, which combines 100-year flood protection for portions of the Rio Bairoa, Rio Grande de Loiza, and Rio Gurabo, and 25-year flood protection for Rio Caguitas, would provide for construction of levees, low-velocity earth channels, high-velocity concrete channels, floodwalls, and debris basins. More specifically, the plan would combine 2.8 km of levees and floodwalls along portions of Rio Grande de Loiza; 1.9 km of concrete channels, 1.8 km of gabion-lined channels, and a 24-acre debris basin for Rio Caguitas; 1.3 km of concrete channels, 1.0 kilometer of earth channels, 0.6 km of gabion-lined channels, 1.0 km of levees, and a 17-acre debris basin for Rio Bairoa; and 0.7 km of pilot channels and 1.8 km of levees for Rio Gurabo. Twelve major highway bridges would be replaced. Approximately 2.1 million cubic meters of material would be excavated, 1.0 million cubic meters of which would be used for backfill, while the remainder would be deposited at upland sites. The plan would allow for the addition of recreational facilities at Rio Grande de Loiza and Rio Gurabo where linear levee and channel configurations provide potential for bikeway/pedestrian routes. The total first cost of the project, at 1990 price levels, is estimated at $114.5 million. The estimated benefit-cost ratio is 1.5. POSITIVE IMPACTS: In addition to providing flood protection for residents of the above-mentioned communities, the project would significantly enhance opportunities for maximizing the use of existing infrastructure and would considerably expand additional urban development by enhancing 289.5 acres of land for future urban expansion. Annual benefits redounding from the project would amount to $24.9 million. NEGATIVE IMPACTS: The project would require 431.9 acres of easements. Some 540 families residing in the floodplain of the Rio Turabo and Quebrada Los Meurtos would not be protected.

Preparation date: November 21, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LIMESTONE CREEK LOCAL FLOOD PROTECTION, FAYETTEVILLE, NEW YORK. AN - 36401643; 2942 AB - PURPOSE: Construction of flood protection measures on Limestone Creek in the village of Fayetteville, New York is proposed. The study area is located in central New York State approximately seven miles southeast of Syracuse. Limestone Creek is a tributary of Chittenango Creek within the Oswego Watershed. The tentatively selected plan would involve construction of 3,650 feet of levee, 600 feet of concrete floodwall, 325 feet of berm, and 24,000 square yards of riprap. For the stream reach south of the Limestone Plaza Street bridge, a 10-foot levee would extend 1,600 feet along the west embankments; floodwall would be provided in constricted areas. A levee of similar construction would be provided between the Genessee Street bridge embankment and the Limestone Plaza bridge embankment, a distance of approximately 100 feet. Along the east bank of the stream reach south of the Limestone Plaza Street bridge, an 800-foot driven sheet pile floodwall with a concrete cap would be constructed. Along the west bank of the stream reach north of the Limestone Plaza Street bridge, an 1,800-foot levee would be constructed with a height of 9 feet and a 10-foot crown. Along the east bank of the stream reach north of the Limestone Plaza Street bridge, flood protection would be provided by either a 700-foot berm or backfilling and elevation of potentially affected properties. Riprap bank protection, snagging, and internal drainage facilities would be provided as necessary. The estimated first cost of the project is $2.37 million at February 1987 price levels, and the benefit-cost ratio is estimated at 2.38. POSITIVE IMPACTS: Protection from the 100-year-frequency flood on Limestone Creek would be provided for Fayetteville residents and businesses located on the 130-acre floodplain. Flood-related health and safety hazards would be substantially reduced. Demand for emergency services would be reduced during flood periods, and the need for flood insurance would decline. NEGATIVE IMPACTS: Three residences, including two houses and a trailer, would be displaced. Levee construction would necessitate the removal of vegetation along the west bank of the stream reach south of the Limestone Plaza Street bridge. Construction activities could degrade fish habitat, and levees could permanently affect the quality of the fishery. Clearing and snagging and construction activities would result in temporary increases in noise levels and traffic disruption, as well as temporary degradation of area aesthetics.

Preparation date: November 20, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LIMESTONE CREEK, MANLIUS, NEW YORK: SECTION 205 FLOOD CONTROL STUDY. AN - 36393193; 2943 AB - PURPOSE: Flood control measures are proposed for Limestone Creek and the West Branch of Limestone Creek in the village of Manlius, New York. The village lies eight miles southwest of Syracuse. The two streams under consideration flow through the village, joining just outside the corporate limits. Under the tentatively selected plan, the project would involve some instream channelization, construction of a diversion control structure, and construction of a high-flow diversion channel. Portions of the channel work would incorporate fabric-formed concrete and/or riprap stone erosion protection. This extensive erosion protection would accommodate the very high design-stream-flow velocities passing through the area during potential flood periods. The existing channel in the upper reach of the Manlius area would be shaped and lined with heavy stone riprap in the transition zone (approximately 250 feet) and fabric-formed concrete for the remaining reach length (800 feet). This upper stream reach extends from the project upstream limit to Production Products, Inc. A new Route 173 bridge would be constructed over the main branch of Limestone Creek to allow for new channel dimensions. A simple constriction and weir diversion structure would be constructed just downstream of Production Products, Inc. to redirect some high flow through the newly excavated high-flow diversion channel. The existing channel in the lower reach area (from the control structure to the creek confluence of the main and west branches) would be excavated to provide for up to five additional feet of depth; channel stabilization measures would be taken. A tributary located upstream of the control structure would be relocated. The new channel, 30 feet wide and 8 feet deep, would be excavated from the diversion structure behind the Tyler Court development to the confluence of the main and west branches of the creek, a distance of 1,300 feet. Erosion protection measures would be implemented in the confluence area. The estimated annualized cost of the project is $362,280, and the benefit-cost ratio is estimated at 1.51. POSITIVE IMPACTS: Flood damage reduction would preserve the economic and social well-being of the community. Protection of Production Products, Inc. would ensure that the company could operate at nearly full capacity without interruption. The placement of riprap and other stabilization measures would preserve the status of Limestone Creek as one of the state's prime trout streams. NEGATIVE IMPACTS: The house on the southeast corner of the existing Route 173 bridge and a garage associated with Production Products, Inc. would be displaced. Stream channelization and protection would alter the appearance of the streams and displace benthos, and new channel excavation would displace land. Both riparian and terrestrial habitat would be disturbed.

Preparation date: November 20, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - US HIGHWAY ROUTE 89, LOGAN CANYON HIGHWAY, CACHE AND RICH COUNTIES, UTAH. AN - 36401692; 2918 AB - PURPOSE: Improvement of US Highway 89 through Logan Canyon in Cache and Rich counties, Utah is proposed. US 89 extends from the Mexican border to Canada. The 28-mile section under consideration extends from Right Fork, approximately nine miles east of Logan, to Garden City. The road passes through the Wasatch-Cache National Forest. Improvements considered include widening of the roadway and shoulders, flattening of curves, replacing and widening bridges, adjusting the road gradient, improving signing, providing climbing lanes and recreational turn-outs, and/or realigning selected roadway sections. In addition to the No Action Alternative, seven complete project alternatives are currently under consideration: Alternative 1 would improve the highway to national highway standards for a two-lane, 40-foot-wide minor arterial road; Alternative 2 would improve the roadway the same as under Alternative 1 and realign the Rich County section to the north of the existing alignment; Alternative 3 would improve the roadway the same as under Alternative 1 and realign the Rich County section to the south of the existing alignment; Alternative 4 would improve the highway to modified national highway standards for a two-lane, 34-foot-wide minor arterial road in the middle canyon section and to Alternative 1 standards elsewhere; Alternative 5 would provide selective improvements, including bridge replacements, turning and climbing lanes, minor realignments, turnouts, and signing; Alternative 6 would provide spot improvements, including bridge replacements, climbing lanes, parking area pavement, realignments, turnouts, and signing; and Alternative 7, a composite alternative, would involve spot improvements in the lower middle canyon, widening to 34-feet in the remainder of the middle canyon, and widening to 40-feet in the remainder of the upper canyon. Estimated construction costs range from $15.6 million to $50.1 million, depending on the alternative selected. POSITIVE IMPACTS: The project would improve a segment of substandard highway linking two important cities and provide access to regional recreational resources. Access to recreational areas in the Wasatch-Cache National Forest, the Bear Lake area at the eastern end of the segment, and Yellowstone National Park would improve significantly. Air quality within the canyon would remain stable or improve. NEGATIVE IMPACTS: Any action alternative would result in impacts to national forest recreational and cultural resources, with one to eight sites being affected. From 13 to 161 acres of new rights-of-way would be developed. Fishing could be hampered at one to two locations, and some stream modification could be required. Up to 25.2 acres of wetlands could be displaced, upland habitat would be lost, and winter range habitat could be lost. Highway construction would mar forest visuals.

Preparation date: November 19, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LAKE CATAMOUNT RESORT, ROUTT COUNTY, COLORADO. AN - 36409606; 2869 AB - PURPOSE: Construction of a year-round recreational resort associated with Lake Catamount near Steamboat Springs in Routt County, Colorado is proposed. The resort would be located in the Yampa River Valley, approximately seven miles south of Steamboat Springs. The area is accessed by County Road 18 and Colorado Highway 131, both of which are linked to US Highway 40, north of Lake Catamount. Lake Catamount Joint Venture has applied for a Special Use Permit that would allow development and use of National Forest System lands located in portions of the Harrison and Green Creek drainages. Development is proposed on both public lands within the Routt National Forest and adjacent private lands. When completed, more than 2,000 acres of ski runs would be provided for a total capacity of 12,000 skiers at one time (SAOT), with more than 800 acres of trails, 600 acres of gladed ski runs, and additional natural skiing terrain. The project would also include construction of 13 chair lifts and 1 gondola. Snowmaking would supplement natural snow on lower portions of the area, utilizing 193 acre-feet of water from Lake Catamount each year. A 40,000-square-foot mountain-top restaurant would be constructed, as well as a smaller restaurant, a ski patrol building, and other necessary maintenance buildings. Access to the top of the mountain would be provided via a 4.7-mile road extending from Smoky Bear Curve on US 40. Another 18 miles of secondary roads would service lift terminals. The ski area would be developed in four five-year phases. Ski developments would occur on the western face of Mt. Baldy, on the facing slopes of the Harrison Creek drainage, and on the north and south facing slopes of the Green Creek drainage. The base area development, to be constructed over 35 years, would include 3,700 dwelling units, 1,000 hotel rooms, commercial space, recreational space, and wildlife management areas. POSITIVE IMPACTS: Recreational development in the area would be consistent with the Routt National Forest management plan and would generally aid in providing recreational opportunities for regional residents. Local employment rolls and other positive socioeconomic indicators would increase significantly. NEGATIVE IMPACTS: Landslide hazards would affect portions of the lower slopes of the mountain where ski lifts and runs would be developed. Ski trail and lift terminal grading and road construction would expose soils to erosion and reduce the vegetative cover. Water yield for all major drainages in the area, except the Yampa Tributary, would increase. Changes in runoff could modify channel hydraulic conditions and impact channel stability at certain locations within the area proposed for development. The Danvers Creek drainage could be significantly affected. Sediment loading to Lake Catamount could increase from on-site watershed disturbance or project-created channel instability. Water quality could decline due to urban development, wastewater treatment system effluent, dredging and filling activities, and slope development. Approximately 33 acres of wetlands and associated wildlife habitat would be lost. Significant elk habitat would be lost or otherwise affected, leading to a substantial reduction in the Catamount elk herd, and the local black bear population would decline. Burning of wood in fireplaces and woodstoves would result in violation of air quality standards under certain conditions. The increase in population would reduce the quality of life for some residents and place stress on social services and the transportation system.

Preparation date: November 16, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FEDERAL AID PRIMARY ROUTE 407 (ILL. 336) FROM US ROUTE 24 AT THE NORTHERN TERMINUS OF ILLINOIS ROUTE 336 TO SOUTHEAST OF CARTHAGE, ADAMS AND HANCOCK COUNTIES, ILLINOIS. AN - 36407619; 2907 AB - PURPOSE: Construction of a four-lane, partially access-controlled, divided highway is proposed in Adams and Hancock counties in midwestern Illinois. The highway would begin at US 24 at the northern terminus of Illinois Route 336 and extend in northerly and northeasterly directions to a point southeast of Carthage. The new 32-mile highway section, to be designated as Federal Aid Primary 407 and marked as Illinois Route 336, would be an arterial facility. Traffic would be separated by a 50-foot-wide median. Access to single-family residences and farms would generally be maintained either by direct access to the highway or by frontage roads and service drives. Of the seven build alternatives originally developed for study, two remain under consideration, as well as the No Action Alternative. The build alternatives, designated E-1 and WE-1, would have interchanges at US 24, Illinois Route 61, and Illinois Route 94. Stream crossing structures would carry the E-1 alignment across Rock Creek, South Fork of Bear Creek, and Slater Creek. Road closures would be implemented at TR 138 and TR 270 under Alternative E-1. Stream crossing structures would carry the WE-1 alignment across Rock Creek, Ursa Creek, South Fork of Bear Creek, and Slater Creek. Road closures would be implemented at TR 138, TR 118, and TR 270 under Alternative WE-1. Project construction would be phased to provide usable sections over the course of several construction seasons. Estimated costs of alternatives E-1 and WE-1 are $90 million and $92 million, respectively. POSITIVE IMPACTS: The project would provide fast, safe, efficient travel within and through the study area via a continuous north-south route. The new highway would facilitate economic development in western Illinois, improve traffic circulation among western Illinois communities, provide a safe divided facility to accommodate high-speed traffic, and provide system continuity from Quincy to US 136. NEGATIVE IMPACTS: Respective rights-of-way requirements for alternatives E-1 and WE-1 would result in the displacement of 815 or 862 acres of land, including 2.1 or 1.8 acres of wetlands, 667.9 or 687.7 acres of croplands, 61.5 or 72.6 acres of pasturelands, 14.5 or 18.8 acres of hayfields, 24.7 or 20.2 acres of developed land, 7.4 or 7.6 acres of upland forests, 9.4 or 7.6 acres of nonnative grasslands, 8.4 or 21.9 acres of floodplain forests, and 14.1 or 18.8 acres of shrublands. Lesser amounts of forbland, ponds, native grasslands, and barren ground would be displaced. The project would cross three or four streams, but there would be no floodplain encroachment. Habitat of the Indiana bat, an endangered species, would be affected, and some increases in wildlife mortality associated with highway operations in the area would be expected. Annual property tax losses due to land displacement would amount to $55,000. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.)

Preparation date: November 11, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CORRIDOR ""X'' FROM US HIGHWAY 78, APPROXIMATELY EIGHT MILES WEST OF JASPER TO NEAR THE WALKER/JEFFERSON COUNTY LINE, WALKER COUNTY, ALABAMA (PROJECT DE-471(24)). AN - 36408113; 2895 AB - PURPOSE: Construction of a four-lane highway in Walker County, Alabama is proposed. The highway would begin at US Highway 78 approximately eight miles west of the city of Jasper and extend eastward to a point near the Walker/Jefferson County Line, a distance of 28 miles. The project would constitute a section of Corridor X of the Appalachian Development Highway Program. The highway, which would be a limited-access facility, with access at interchanges only, would feature two 24-foot pavements, with 10-foot outside and 6-foot inside shoulders, separated by a 64-foot minimum raised median within a 300-foot rights-of-way. Two project segments have been developed for consideration of alternatives. Alternate I for segment A/B would begin on US Highway 78 and extend to the south for approximately one mile, where it would turn eastward to parallel US 78 for approximately six miles before turning southeasterly to intersect with Alternate IV. Alternate IV for segment A/B, which begins at the same point as Alternate I on US 78, would extend east for approximately five miles and turn southeasterly to intersect with Alternate I; approximately the first five miles of Alternate IV would use the existing two lanes of US 78, constructing only two additional lanes. Alternates I and IV for the A/B segment would extend 8.13 miles and 7.79 miles, respectively. Alternate I for segment C/D would begin immediately east of the proposed project interchange with Alabama State Route (SR) 269 and proceed in a southeasterly direction for approximately six miles before turning in an eastward direction shortly after crossing Walker County Road 22 and proceed eastward to alternates II or III. Alternate II for segment C/D would begin near the intersection of SR 269, extend eastward for one mile, turn southeastward, and intersect Alternate III near the southern boundary of the city limits of Cordova; Alternate III for segment C /D would begin immediately east of the SR 269 interchange, extend eastward for four miles, turn southeastward, pass through a segment of Cordova City, and terminate at the Walker County Route 61 interchange. Alternates I, II, and III for segment C/D would extend 8.47 miles, 8.57 miles, and 9.11 miles, respectively. Depending on the combination of alternates chosen, project cost estimates range from $55.7 million to $74.9 million. POSITIVE IMPACTS: Corridor X, when completed, would extend from Fulton, Mississippi to the metropolitan area of Birmingham, Alabama. The corridor would provide a significant boost to the Appalachian regional economy. Interchanges would connect isolated local communities to a regional transportation network. In the immediate area of the project, the highway would enhance safety by diverting truck and other through traffic from the downtown area of Jasper. Emergency response would improve significantly. NEGATIVE IMPACTS: Alternates I and IV of the A/B segment, would displace 15 residences and 1 business and 18 residences and 1 business, respectively. Alternates I, II, and III of the C/D segment would displace 12 residences, 15 residences, and 7 residences, respectively. Depending on the alternate selected, small areas of wetlands could be filled and channelization of some creeks could be necessary. In any event, land providing forested wildlife habitat and some small parcels of arable land would be converted to highway uses. Some businesses in the city of Jasper could experience a decrease in business due to the diversion of through traffic to the new highway. Highway traffic would increase noise levels within the corridor.

Preparation date: November 6, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CHEHALIS RIVER AT SOUTH ABERDEEN AND COSMOPOLIS, WASHINGTON: FLOOD CONTROL PROJECT (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JANUARY 1977). AN - 36408814; 2947 AB - PURPOSE: Implementation of a flood control plan for the Chehalis River at South Aberdeen and Cosmopolis, Grays Harbor County, Washington is proposed. This supplement to the final environmental impact statement (FEIS) of January 1977 addresses changes in the initial design of the authorized flood control project and compares the initial design with the current project design, which is based on studies made since 1984. The supplement also provides additional design information requested by resource agencies commenting on the 1977 FEIS. The initial design of the project would have required 53 acres of land to construct a 24,700-foot-long levee system. Of this length, 22,500 feet would have been earth embankment levee and 2,200 feet would have been concrete floodwall. Riprap would have been placed on levee side slopes along 5,900 feet of the levee. Pumping stations and gated drainage culverts were to be constructed at Devonshire, Shannon, and Miller sloughs and Alder and Mill creeks. Riprap would also have been required on some 8,480 feet of drainage channel banks upstream and downstream of the drainage structure. Areas adjacent to the levee were to be overbuilt to provide landscaping opportunities. As currently proposed, the project would include 11,550 feet of earth embankment levee, 6,010 feet of high ground, and 4,740 feet of sheetpile floodwall adjacent to the south bank of the Chehalis River in the cities of Aberdeen and Cosmopolis. Land required permanently for the project would total 45.56 acres. No riprap would be required on the levee slopes. Five major drainage structures utilizing flap and sluice gates would be constructed to control the flows of Mill and Alder creeks and Devonshire, Shannon, and Miller sloughs. Approximately 470 linear feet of riprap would be required at the drainage structures. Landscaping measures would be implemented to restore 2.2 acres of estuarine wetlands and 0.6 acres of shrub/forest wetlands to mitigate for project damages to wetlands. Estimated project construction costs amount to $12.0 million, while annual operation and maintenance costs are estimated at $35,000 over the 100-year project life. POSITIVE IMPACTS: Compared to the initial design, the current design would impact 13 fewer acres of habitat and 7.7 fewer acres of wetlands. Existing and future residential development and commercial properties would be protected from flooding. Average annual inundation reduction benefits under future growth conditions would amount to more than $1.559 million, reflecting an approximate reduction of 99 percent in the current level of average annual flood damages of $1.578 million. Expenditure of project funds would stimulate the economy of the Hoquiam-Aberdeen-Cosmopolis area of Grays Harbor County. NEGATIVE IMPACTS: Construction activities would destroy 7.9 acres of habitat, of which 4.3 acres would be wetlands (0.9 acre of estuary and 3.4 acres of shrub/forest). Three roads, three houses, and one shed would require relocation, as would numerous utility lines. Rights-of-way requirements would total 49.82 acres, of which 2.16 acres would be used only during construction. Affected acreage would include 39.52 acres within the city of Aberdeen, 7.5 acres in Cosmopolis, and 2.8 acres in Grays Harbor County.

In most cases, the wall is constructed from a soil-bentonite-concentrate slurry. The walls are effective for most conditions, but sometimes are subject to construction, cost and compatibility problems. The use of an interlocking 'Z' section steel sheet pile barrier wall was found to be an effective approach to containment of contaminated soil and groundwater at the Southern Maryland Wood Treatment (SMWT) Superfund site. Factors that may influence selection of a sealed sheet pile barrier wall over a slurry wall include: structural integrity, chemical compatibility, constructability, property access constraints, cost and compatibility with the final remedy. Based upon experience at the SMWT Superfund site, the sheet pile barrier wall offers a constructible, cost-effective and technically sound option to the traditional slurry wall for temporary containment at hazardous waste sites.

AN - 36407952; 2933 AB - PURPOSE: Alteration of the management plan for the Prado Dam in Riverside and San Bernardino counties, California is proposed to allow the dam to operate as a water conservation and storage facility. The dam, which is located on the Santa Ana River 3 miles upstream of the Orange County line and 31 miles upstream of the Pacific Ocean, is currently operated for flood control, with authorization for incidental water conservation measures. Project facilities include an earthfill embankment rising 106 feet above the stream bed, with a crest length of 2,280 feet, and a reservoir behind the dam, contained at a spillway crest of 543 feet and holding 196,000 acre-feet of water. The land covered at this elevation is approximately 6,630 acres; 9,741 acres are covered at the 556-foot take line. The watershed supplying runoff to Prado occupies an area extending from the city of Pomona to Mount San Antonio along the crest of the San Gabriel and San Bernardino mountains, including Big Bear Lake, to Mount San Gorgonio and San Gorgonio Pass, and including Lake Elsinore. Various recreational uses, wildlife resources, and cultural resources are present in the basin associated with the dam. The proposed project would allow storage of water at Prado Dam after the main winter flood season to provide recharge water for spreading facilities downstream of the dam. Three alternative conservation pool maximum elevations are under consideration as well as the present operational regime. The present operational plan results in the delivery of approximately 212,900 acre-feet of water annually to the vicinity of the spreading grounds in the Santa Ana River, based on inflows adjusted to 1988 conditions. Of that amount, approximately 171,700 acre-feet per year are available for diversion, based on a 450 cubic-foot-per-second spreading ground infiltration rate. The percentage of conservable water is approximately 81 percent. This conservation water plan is being implemented with the 490-foot debris pool. The three alternatives would provide for a conservation pool at 495 feet, 500 feet, or 505 feet. Additional conservable water increases arithmetically with increases in elevation of the seasonal pool. The respective increases in conservable water for crest elevations of 495, 500, and 505 feet are 1,456 acre-feet, 3,179 acre-feet, and 4,634 acre-feet, based on 1988 conditions. The preferred alternative is for a seasonal water conservation pool expanded to 500 feet. POSITIVE IMPACTS: In addition to providing the same level of flood control provided historically by the Prado Dam, increasing the conservation pool elevation and associated releases would result in water savings and improvement in the availability and quality of water resulting from project regulation and operation. Balanced resource use through improved regulation would ensure conservation of as much water as possible and maximization of all project functions consistent with project management. NEGATIVE IMPACTS: Primary impacts would affect biological resources, cultural and historic resources, and recreational uses within the basin. Cultural resource sites and the least Bell's vireo, an endangered plant species, would be inundated by elevation of the water conservation pool.

Preparation date: October 31, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BEARTRACK GOLD PROJECT, SALMON NATIONAL FOREST, LEMHI COUNTY, IDAHO. AN - 36409578; 2854 AB - PURPOSE: Issuance of a permit to Meridian Gold Company for the operation of an open-pit, cyanide heap leach gold mine on the Salmon National Forest near the historic town of Leesburg in Lemhi County, Idaho is proposed. Forestry, rangeland, and agriculture are the dominant land uses in the county. Five alternatives, including a no action alternative, are under consideration. The applicant's proposal would involve two open-pit mines covering 129 acres, a heap leach pad and associated ponds covering 228 acres, three waste dumps covering 234 acres, and other facilities such as buildings, roads, and powerlines on 104 acres of private and National Forest System lands. The estimated mine life would be seven years, during which 25 million tons of ore and 50 million tons of waste rock would be produced. Ore would be processed using a cyanide heap leach method to extract the gold. Water would be supplied from dewatering of the open pits and precipitation. Solid wastes would be disposed offsite in the Lemhi County landfill or at an approved site for petroleum or other hazardous materials. Sanitary waste facilities would consist of septic tank leach field systems. Handling of all cyanide solution would be done on the leach pad and in ponds that would be lined to prevent leaks of cyanide. The current Napias Creek Road would be reconstructed and upgraded to a two-lane facility. To the extent practical, surface disturbances would be reclaimed on an annual basis to reduce erosion and enhance stability and vegetative productivity. Upon abandonment, facilities, equipment, and materials would be removed and most disturbed areas reshaped to ensure stability, then covered with topsoil and revegetated. Approximately 512 acres would be recontoured and 568 acres would be covered with topsoil and revegetated. Other than the applicant's proposal, described above, the three other action alternatives involve reducing the rate of mining activities to lessen socioeconomic impacts, altering waste dump planning and configuration, higher design standards for the heap pad liner and permanent surface water diversions to protect water quality, and reclamation design changes. POSITIVE IMPACTS: Gold production would increase the nation's reserves of this precious and economically important metal. From 100 to 150 persons would be employed during full production at an estimated annual payroll of $3.0 to $4.0 million. NEGATIVE IMPACTS: Approximately 705 acres would be disturbed, resulting in erosion and associated sedimentation of receiving waters. Disturbed lands, which would include wetlands and forested lands, could be invaded by noxious weeds. The Lemhi penstemon and the Twin bladderpod, both of which are listened as endangered species, are located in the area that would be mined. Rangeland and wildlife habitat would be displaced. Fishing pressure would increase in streams in the vicinity of the mine. Waste dumps would have some probability of shallow mass failures over the long term due to benched reclamation of the faces and some probability of acid or leachate discharge. Cultural resources would be disturbed, and the recreational and aesthetic values of the area would decline somewhat. The closure of certain roads would be required, affecting access to the Leesburg Area and Napias Creek, and vehicular traffic on area roads would increase somewhat. Significant population changes, along with the attendant socioeconomic effects, would accompany the mining operation.

Preparation date: October 24, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD CONTROL MASTER PLAN, CLARK COUNTY REGIONAL FLOOD CONTROL DISTRICT, LAS VEGAS VALLEY, CLARK COUNTY, NEVADA. AN - 36406082; 2941 AB - PURPOSE: Construction and operation of flood control facilities in the Las Vegas Valley of Clark County, Nevada are proposed. The study area encompasses 984 square miles in southeastern Nevada and includes portions of Las Vegas, North Las Vegas, Boulder City, Henderson, and unincorporated portions of Clark County. Flood control facilities would include reinforced concrete pipelines, precast boxes, lined and unlined channels, floodways, dikes and levees, detention and debris basins, and bridges. Under the preferred plan, known as the Detention/Conveyance Alternative, a series of detention basins would be developed to reduce peak flows to levels that would be accepted by the existing downstream conveyance system with little or no major capacity improvements. The general configuration and spatial location of the system would involve a number of large detention basins designed to slow the release of water to a series of interrelated facilities, including lined and unlined channels, reinforced concrete pipelines, conduits, and floodways. A 10-year facilities construction plan has been developed for fiscal years 1988-1989 through 1997-1998. Most of the construction effort would be directed toward construction of lined channels. Eighty channel segments would be constructed, representing an estimated 294,500 linear feet of construction. Eighteen box conduits and 28 box culverts would be built, along with 14 dikes/levees, extending a total length of 78,050 linear feet; most of the latter would be placed around the perimeter of the valley. The 10-year facilities would also include 19 pipeline segments (12,840 linear feet), 13 bridges (1,900 linear feet), and 5 floodways (80,000 linear feet). Miscellaneous facilities include one set of inlet works, one set of outlet works, and two culverts. A total of 21 detention basins and 1 debris basin, covering a total of 1,426 acres, would be provided. POSITIVE IMPACTS: The provision of flood protection to one of the fastest growing urban centers in the nation would help prevent loss of life and property during flash flood events in the historical floodplains and alluvial fans. The centralized plan would ensure a concerted, organized approach to flood control where current protection measures are fragmented. Of all the plans under consideration, the preferred plan would provide the greatest potential for multiuse recreational facilities. NEGATIVE IMPACTS: The plan would result in 100.84 miles of construction disturbance for linear facilities, such as channels, pipelines, and dikes/levees, as well as 2.23 square miles of disturbance from construction of detention and debris basins. Structural measures could be subject to seismic activity, soil movement, and strong winds. The presence of caliche soils and shallow groundwater could interfere with routine construction, requiring special construction practices. Structural measures could interfere with mining claims. Flood discharges from the project area could result in downstream flooding. Botanical and other wildlife resources could be affected by construction activities and the existence of facilities. Facilities would constitute topographic alterations and visual disturbances. Archaeological, historical, and Native American resources would be impacted.

AN - 36407427; 2904 AB - PURPOSE: Construction of two connector roads in the northern and eastern portions of the Atlanta Metropolitan Area of Georgia is proposed. The first connector, which would extend 32 to 34 miles, would link Interstate 75 (I-75) in Bartow County to State Route (SR) 371 in Forsyth County. Four build alternatives and a No Build Alternative are under consideration for this connector. Interchanges would be constructed at I-75, SR 108, SR 5 Business, I-575, SR 140, East Cherokee Drive, SR 372, and SR 371. Depending on the alternative chosen, an additional interchange could provide access to SR 20. The second connector, which would extend 24 miles, would link I-20 in Newton County to SR 316 in Gwinnett County. Only one Build Alternative and a No Build Alternative are under consideration for this connector, which would begin at I-20 at a point 0.25 mile east of the Newton/Rockdale County Line, continue north until it crosses County Road (CR) 86, and turn northeast to the Rockdale/Walton County Line, where it would turn northwest to its northern terminus at the SR 316 Extension. Interchanges would be provided at I-20, SR 138, SR 20, SR 10/US 78, SR 20 (north of Loganville), CR 267 (New Hope Road), and the SR 316 Extension. The estimated cost of the combined projects ranges from $646.2 million to $687.7 million. POSITIVE IMPACTS: The connectors would provide for the transportation needs of the four northern and northeastern portions of the metropolitan area, which are growing at a rapid rate. The new highway links would boost residential and commercial development in Cherokee County and industrial and commercial revitalization in Bartow and Forsyth counties. In combination with other major highways in the area, the connectors would form a circumferential route connecting US 411/US 41, I-75, I-575, GA 400, I-985, I-85, SR 316, US 78, and I-20 from Cartersville to Conyers, Georgia. Through traffic would be removed from Atlanta's congested highways. NEGATIVE IMPACTS: Rights-of-way requirements would displace 2,097 to 2,316 acres of farmlands, 130.4 to 156.9 acres of wetlands, 100 to 200 residences, 4 to 13 businesses, and 2 farms. The highways would traverse floodplains in 21 or 22 locations, and construction activities would encounter 11 to 14 archaeological sites and 1 or 2 hazardous waste sites. The project would pass in the vicinity of three to four historically significant sites. Noise impacts resulting from traffic using the highways would affect 141 to 153 sensitive receptors.

AN - 36409680; 2899 AB - PURPOSE: Construction of a bypass in and near the city of Hollister is proposed in San Benito County, California. The project would begin approximately 3.5 miles west of downtown Hollister, at the Union /Mitchell Road/Route 156 intersection, and end some 3.5 miles north of downtown near the San Felipe Route/Route 156 intersection, bypassing approximately 7.0 miles of the existing state route. The new facility would be a two-lane, limited-access expressway on new alignment, essentially bypassing Hollister to the north and west of town. It would consist of a paved section 40 feet wide with two 8-foot shoulders. A 175-foot rights-of-way would be purchased for eventual construction of a four-lane facility. Signalized intersections would be provided where the alignment departs from and rejoins existing State Route (SR) 156 at SR 25. The project would include a multiple-span concrete overhead bridge across the San Benito River and a concrete overhead bridge across the Southern Pacific Railroad. The preferred alignment would depart from the existing highway at the city sewage treatment plant and rejoin it north of the airport. Noise control features could be provided to mitigate noise levels for five residences. The estimated cost of the project is $20.0 million. POSITIVE IMPACTS: The bypass would provide a means for through traffic and large trucks to circumvent the downtown area of Hollister, relieving congestion in the downtown area and enhancing long-distance travel in the region. Noise, air pollutants, and other nuisances and safety hazards associated with traffic congestion in the downtown area would be alleviated. Transportation needs of the community would be met within the SR 156 corridor over the next 20 years. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of 165 acres of land, including 100 acres of farmlands and 2 residences; 300 square feet of wetlands associated with Santa Ana Creek would lie within project rights-of-way. A strip of riparian vegetation along the San Benito River would also be impacted. Without mitigation, six residences would be exposed to excessive noise levels due to traffic on the new bypass. Visual impacts would result from the proximity of the facility to a sewage treatment plant and noise control barriers.

AN - 36393419; 2897 AB - PURPOSE: Construction of a four-lane divided, partially controlled-access facility in Benton and Washington counties, Arkansas is proposed to connect Siloam Springs to Springdale. The 16.3- to 19.1-mile highway, to be known as Highway 71 (US 412), would be constructed on a combination of new and existing rights-of-way, extending 45 to 150 feet in each direction from the center line. All alternatives would begin at the five-lane section just east of the Tontitown area and proceed west, roughly paralleling US 412 and connecting with the five-lane section of US 412 at Siloam Springs. Alternatives under consideration include reconstruction of the existing highway and 10 new location alternatives. All alternative alignments on new location would have two 12-foot lanes in each direction, separated by a variable-width median. The alternatives using existing US 412 with an eastern termini of State Highway 112 to just west of Tontitown would have a five-lane curb-and-gutter section between those two points. A similar section would be used just east of Siloam Springs, where the project transitions from a four-lane divided to the existing five-lane section. Access would be partially controlled with intersections at selected public roads. POSITIVE IMPACTS: By providing an improved east-west route between Siloam Springs and US 71 in Springdale, the project would enhance economic development in northwest Arkansas. Congestion would be reduced and safety improved on US 412 between project termini. The urbanized areas of northwest Arkansas would be connected to the Cherokee Turnpike leading to the urbanized area of Tulsa, Oklahoma. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 600 to 700 acres of land, including wildlife habitat and 10 acres of wetlands. Conversion of land to highway uses would also result in the displacement of households, businesses, and nonprofit organizations. The project would encroach into the Logan Cave National Wildlife Refuge as well as some floodplain lands. Historic and archaeological sites would be encountered during construction. The highway would affect the Tontitown City Park and recreational lands in the Ozark and St. Francis national forests and encroach visually on adjacent natural lands; visual encroachments would include major cuts and fills.

A study was performed using frequency analysis and the truncation method, applied to 18 gaging stations in the Scioto River Basin in Ohio. By applying the plotting position method to the streamflow data, droughts for the 100-year recurrence interval were defined. The flows corresponding to the 100-year droughts defined in this manner are practically nil and do not express important elements of drought such as duration and deficit. From the water management point of view, a 100-year drought definition using the frequency analysis is impractical since it refers to no flow. Based on the method of truncation level, drought duration and deficit can be defined and are shown to have strong correlation coefficients for all gage stations studied. Flows of drought using the truncation method gradually decrease with an increase in truncation level, where flows of 95 % are approximately equal to those of two-year droughts defined by the plotting position. An increase of truncation level reflects an increase of drought severity so that a water management measure can be taken starting from a lower level of drought severity. This will provide enough time for the public to adjust accordingly. However, values of truncation level used in the truncation method have to be updated whenever new data become available.

RUSSELL DAM AND LAKE, ELBERT AND HART COUNTIES, GEORGIA AND ANDERSON AND ABBEVILLE COUNTIES, SOUTH CAROLINA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1979). AN - 36409836; 2938 AB - PURPOSE: Installation of pumped storage hydroelectric facilities is proposed at Richard B. Russell (RBR) Dam and Lake (formerly Trotters Shoals Lake) on the Savannah River in Elbert and Hart counties, Georgia and Anderson and Abbeville counties, South Carolina. The primary facilities would include four 75 megawatt (MW) pump turbines that would permit pumped storage operations and increase the electrical power generating capacity of the project from 300 MW to 600 MW. This document constitutes a draft supplement to the final environmental impact statement (EIS) of October 1979. Based on information available at the time the final EIS was issued, it was concluded that pumped storage operations would not have a significant adverse effect on the J. Strom Thurmond (JST) Lake fishery. Consequently, the final EIS did not contain any recommendations for fish protection measures. Since that time, additional studies have been conducted concerning potential fish entrainment during pumped storage operations. The need for fish protection measures prior to pumping water back from JST Lake to RBR Lake also received further consideration, including structural methods (bar rack), nonstructural or behavioral alternatives (light fish protection or high-frequency sound systems), and operational measures (various restrictions on unit operations). The tentatively selected alternative would provide for the installation of a high-frequency sound and light fish protection system prior to operating the pump turbines. The plan would also include a phased operational plan for pump turbines. The pump turbines would be tested and extensive entrainment data collected prior to committing the units for dependable commercial power production to ensure that the units were operating in an environmentally acceptable manner. The installation cost of the sound and light system is estimated at $400,000. POSITIVE IMPACTS: The residents of the Southeastern Power Administration's 10-state market area would benefit from pumped storage power. The project would make available efficient power capacity to private and industrial consumers for peak-load energy requirements at relatively low cost. Fish protection facilities would decrease the entrainment of large numbers of young fish and eggs during pumping and generating operations. NEGATIVE IMPACTS: Some fish would be lost as a result of pumped storage operations. Removal of the rocks from the tailrace and dredging 1.5 million cubic yards of material from a 1.2 mile section of the tailwater would permanently change the configuration of the affected tailwater areas. There would be a short-term adverse effect on power production.

Preparation date: September 27, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SANTA FE-LOS ALAMOS CORRIDOR STUDY, PHASE C, SANTA FE AND LOS ALAMOS COUNTIES, NEW MEXICO (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF JULY 1988). AN - 36406058; 2909 AB - PURPOSE: Construction of a shorter, more direct route between Santa Fe and Los Alamos, through Santa Fe and Los Alamos counties, New Mexico is proposed. The facility, to be known as State Road (SR) 516, would be a four-lane, divided highway with limited-access control. Four alternatives, extending 19 to 22 miles from the intersection of Interstate 25 (I-25) and the proposed Santa Fe Relief Route near Santa Fe to SR 4 near Los Alamos, are under consideration. Although SR 4 represents the construction limits for all build alternatives, SR 502, Pajarito Road, and East Jemez Road provide access to and from Los Alamos and are documented in this draft supplement to the draft environmental impact statement on the larger highway project. Improvements to the last three roadways are not part of the proposed action. The 22-mile Montoso alignment would require three bridge crossings, ranging in length from 640 feet across Chaquehui Canyon to 2,790 feet across the Rio Grande. The 19-mile Chino Mesa alternative would involve two bridge crossings, including a 1,923-foot crossing of Ancho Canyon and a 3,113-foot crossing of the Rio Grande. The 21-mile Mortandad alternative would involve two bridges, including a 500-foot crossing of Canada Ancha and a 4,562-foot crossing of the Rio Grande; this alternative would also require a temporary 300-foot construction bridge. The 22-mile Sandia Canyon alternative would require two bridges, including a 400-foot crossing of Canada Ancha and a 4,104-foot crossing of the Rio Grande. All four crossings of the Rio Grande would be in the White Rock Canyon area. The terrain from SR 4 across White Rock Canyon is mountainous. Due to the high cost of constructing deep cuts and high fills in this area, the lanes would be drawn together through this section. An interchange would be constructed to connect the facility to the Santa Fe Relief Route. Depending on the alternative alignment selected and various design decisions, cost estimates for the project range from $150.8 million to $205.5 million. POSITIVE IMPACTS: Safety conditions in the transportation of hazardous wastes from the Los Alamos National Laboratory to storage facilities would improve, and access from Santa Fe and the surrounding area to the laboratory would be eased. Egress from the laboratory for civil defense and other emergency conditions also would be improved. Construction activities would employ 1,143 to 1,560 persons. The Villa Linda Mall in Santa Fe would be more accessible to potential customers. Access to tourist and other recreational attractions in the Bandelier National Monument, the Jemez Mountains, Pajarito Ski Area, and Caja del Rio would improve. NEGATIVE IMPACTS: Placement of the bridge across the Rio Grande would degrade the visual quality of White Rock Canyon significantly and could affect the scenic quality of Bandelier National Monument. Rights-of-way acquisition requirements would remove productive grazing land, result in some private property displacements, and affect land uses within the Santa Fe National Forest. Retail activity would decrease in Los Alamos. Bureau of Land Management and Forest Service lands would be displaced, reducing payments from these sources in lieu of local tax losses. Threatened and endangered animal and plant species could be impacted. Numerous archaeological sites could be affected.

AN - 36401351; 2849 AB - PURPOSE: Construction of two 393-megawatt (MW) (net) pulverized coal-fired electric generating units is proposed by Old Dominion Electric Cooperative and Virginia Electric and Power Company (Virginia Power) at a new plant site to be located near the town of Clover in Halifax County, Virginia. Each participant will have an undivided ownership of 50 percent of the proposed 786-MW facility. The 848-MW gross (786-MW net) pulverized coal-fired steam electric generating station would be located on a 1,760-acre site along the Roanoke River directly across from Charlotte County. Major station facilities would include two 424-MW gross (393-MW net) pulverized coal-fired units with expected start-up dates of 1994 and 1995; two 14.6-meter (48-foot) high, 232-meter (762-foot) long, and 16-meter (54-foot) wide mechanical draft cooling towers; two 134-meter (440-foot) high stacks; pollution minimum boilers designed to limit oxides of nitrogen to meet a 0.32 pound per million Btu emission limit; a chemical wastewater treatment system; a wet-flue gas desulfurization scrubbing system; a fabric-filter baghouse; dry fixation facilities for treatment of flue gas desulfuration wastes and coal ash; an on-site sludge disposal facility; a 140,000-pounds of steam per hour oil-fired auxiliary boiler and two associated 473,125-liter (125,000-gallon) oil storage tanks; and a loop-track rail spur from an existing Norfolk Southern Railway line. Stack emissions would be controlled by limestone scrubbers, a fabric-filter baghouse, and boiler design. Condenser cooling would be accomplished by the use of mechanical draft cooling towers. Plant water would come from the Roanoke River. An on-site water reservoir with a 30-day capacity would supplement plant water supply during periods of low river flow. Two 5-kilometer (3-mile), 230-kilovolt transmission lines would interconnect the station to the existing transmission grid. Coal would be purchased from southwestern Virginia, eastern Kentucky, and/or West Virginia and transported via rail by the Norfolk Southern Railroad. Trains would be routed to South Boston, Virginia and reconfigured for delivery to the Glover plant in either half- or whole-unit train segments. POSITIVE IMPACTS: Electric power provided by the new units would replace an expiring 300-MW purchase power contract, answer the overall need for additional generating capacity, and provide for future projected capacity of the 12-member Old Dominion Electric Cooperative. Construction and operation of the facility would generate jobs, taxes, and other economic benefits. NEGATIVE IMPACTS: Levels of concentrations for sulfur dioxide, nitrogen oxides, and particulates would increase in the vicinity of the site, but would remain within government standards. Wastewater effluent would be discharged into the Roanoke River. Construction activities would require removal of 275 cubic meters of river bottom material. Site activities would result in the disturbance of 662 acres; most of this land has been used for agricultural purposes. Cultural resources, some of which are eligible for inclusion in the National Register of Historic Places, would be disturbed during site development.

Preparation date: September 27, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - US 64/PITTSBORO BYPASS FROM SR 1514 TO US 64 NEAR B. EVERETT JORDAN LAKE, CHATHAM COUNTY, NORTH CAROLINA. AN - 36393150; 2911 AB - PURPOSE: Widening of existing US 64 from two to four lanes in the east-west traffic corridor through northeastern Chatham County, North Carolina is proposed. The project would extend approximately 3.2 miles from the existing four-lane section west of B. Everett Jordan Lake to the Haw River. The project would also include construction of a northern bypass of the town of Pittsboro west of the Haw River. Additional widening of existing US 64 from the bypass terminus west of Pittsboro to the project limits at Manco Dairy Road (State Route (SR) 1514) would also be included in the project. The bypass would be a four-lane divided highway on new location with full control of access, although some at-grade intersections would be provided initially, with provisions for eventual construction of interchanges. Bypass alternatives would range in length from 8.7 miles to 9.3 miles; the highway widening alternatives, extending from the bypass terminus to Manco Dairy Road, would range from 0.9 mile to 1.9 miles. Interchanges would be provided during the initial construction period at US 15-501 and SR 87, in addition to directional interchanges with existing US 64 at the bypass termini. All other interchanges would be constructed at future dates. Two alternatives for the section from Jordan Lake to the Haw River and four bypass alternatives are under consideration. The estimated total cost of the project ranges from $46.6 million to $50.5 million. POSITIVE IMPACTS: The project would complete a highway planned as part of the North Carolina Transportation Improvement Program since 1986. Regional travel from western North Carolina through Lexington, Asheboro, Pittsboro, and Raleigh to the North Carolina Coast would be improved significantly. Economic development efforts in the southern Piedmont would be furthered. Through traffic would be removed from local arterials in the town of Pittsboro, removing heavy truck traffic from the central business district and historic center of the town. NEGATIVE IMPACTS: Rights-of-way developments would result in the displacement of 13 to 49 residences and 1 to 2 businesses, as well as 218.6 to 291.1 acres of upland forest and 3.7 to 5.8 acres of wetlands. Traffic-generated noise would result in noise level increases of 15 decibels on the A-weighted scale for one to six sensitive receptors, and federal noise standards would be exceeded at one to five locations. The project would traverse 21 to 26 streams, requiring 8 to 10 major drainage structures, and encroach on one floodplain. One historic site and one archaeological site could be affected.

AN - 36384633; 2801 AB - PURPOSE: Construction of a freeway along State Route (SR) 73 from the Interstate 5 (I-5) freeway in the city of San Juan Capistrano to its existing terminus at Jamboree Road in Orange County, California is proposed. Portions of the project would be located within the cities of Newport Beach, Irvine, Laguna Beach, Laguna Niguel, Mission Viejo, and San Juan Capistrano, and unincorporated areas of Orange County. Two build alternatives are under consideration. The Demand Management Alternative would include three general purpose lanes in each direction, with auxiliary lanes for weaving and steep grades, as well as an 88- to 116-foot median for additional capacity as warranted. The Conventional Alternative would include three to five general purpose lanes in each direction, with auxiliary lanes for weaving and steep grades, as well as a 64- to 116-foot median for additional capacity. A high-occupancy vehicle (HOV) facility would be implemented in the median when traffic demand warrants. The Demand Management median would be capable of conversion to concurrent HOV lanes and a fixed guideway rail /transit system. Regardless of the alternative chosen, ramp improvements would be provided on existing SR 73 between Birch Street and Jamboree Road. Under either alternative, the freeway would operate as a toll facility until bonds are repaid. The estimated costs of the Demand Management and Conventional alternatives are $768.3 million and $791.0 million, respectively. POSITIVE IMPACTS: Improvement of transportation facilities within the San Juan Hills Corridor as planned would constitute a central component of a 14-year cooperative planning process incorporating regional land use, transportation, and open space planning concerns. Existing traffic congestion within Orange County, which places pressure on arterial highways located near or parallel to congested interstate freeways, would be lessened significantly. Through traffic would be removed from parallel arterial highways. Air quality within the corridor would improve over existing levels. NEGATIVE IMPACTS: Development of 669.9 to 682.1 acres of rights-of-way would result in 12.7 to 16.6 acres of floodplain encroachment, displacement of 13.8 to 15.2 acres of wetlands, loss of coastal sage scrub and chaparral habitat, restriction of wildlife movements, and both residential and commercial relocation impacts. Either alternative would remove a portion of the Rancho Viejo Bicycle Trail. Highway structures would result in visual impacts to residential users in several communities.

Preparation date: September 19, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OPERATION AND MAINTENANCE OF CORALVILLE LAKE AND THE DOWNSTREAM AREA OF INFLUENCE TO COLUMBUS JUNCTION, IOWA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF SEPTEMBER 1977). AN - 36410475; 2826 AB - PURPOSE: Raising the conservation pool level of Coralville Reservoir on the Iowa River in Johnson County, Iowa, is proposed. This document constitutes a draft supplement to the final environmental impact statement of September 1977 on continued operation and maintenance of the reservoir. The reservoir is operated for the purposes of flood control, downstream flow augmentation, recreation, and migratory waterfowl habitat enhancement. The project area is located five miles upstream of Iowa City. The study area encompasses the Iowa River Basin in Iowa, Johnson, Washington, and Louisa counties, Iowa, but the major area of influence is in Johnson County. The basin of the Iowa River is generally long and narrow, with an average slope of 1.9 feet per mile. The dam creating the reservoir is a rolled earthfill embankment with a maximum crest height of 110 feet above the streambed at elevation 743.0 feet National Geodetic Vertical Datum (NGVD). The dam controls a drainage area extending 3,115 square miles. The current operational plan requires sequential pool level changes through late winter, summer, and fall. The summer pool is the conservation pool, held at an elevation of 680 feet NGVD. The recommended plan for raising the conservation pool would involve a one-step raise from 680 feet NGVD to 683 feet NGVD. The plan would also call for a three-foot variable conservation pool raise for the benefit of migrating waterfowl, an early spring conservation pool drawdown to elevation 679 feet NGVD to provide additional flood control storage, and a modified reservoir release schedule to help minimize the effects of the increased conservation pool elevation on upstream and downstream flood levels. A late winter drawdown to 679 feet NGVD would be dependent on meteorological conditions and resultant hydrologic conditions in the Iowa River and its tributaries. At some time in the future, the reservoir would be reevaluated so that the low-flow augmentation needs downstream of the reservoir could continue to be met. POSITIVE IMPACTS: Based on current estimates, the new conservation pool level of 683 feet NGVD would provide sufficient storage for low-flow augmentation for approximately 20 additional years of reservoir operation. The project would continue to provide downstream flood protection, particularly to Iowa City, and contribute significantly to flood control in the Upper Mississippi River Basin. Low-flow augmentation would continue to provide a reliable water source for Iowa City and for the University of Iowa and sustain the downstream fishery of the Iowa River. Diversified recreation would continue to be available in an area where water-based recreation is extremely scarce. The late winter drawdown would allow storage for conservation during midwestern drought conditions. NEGATIVE IMPACTS: Increasing the level of the conservation pool could increase the water table above and below the lake and would be likely to increase the extent of undesirable algal blooms. Travel on some secondary roads would be disrupted during flood stages, and flood and wave action damage and silt and debris problems would also affect area roads. Loss of outlets for tile drainage systems, continuation of barren area between conservation and flood pool levels, and a probable increase in the frequency of inundation of upstream easement lands would also result.

Preparation date: September 17, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MONTGOMERY POINT LOCK AND DAM, DESHA COUNTY, ARKANSAS. AN - 36392873; 2818 AB - PURPOSE: Construction of a lock and dam within the present channel of the White River is proposed. The immediate study area encompasses approximately one mile in width on both sides of the White River from the present Norrell Lock and Dam to the Mississippi River. The area lies in the east central part of Arkansas, bordered by Desha and Arkansas counties. The underlying problem that necessitates a solution is that when the Mississippi River water elevations fall, in late summer and early fall, the White River drops and the entrance channel (lower 10 miles of the river) becomes shallow, constricted, and misaligned. These reductions create problems for navigation users and the entire system is charged with a lack of dependability for commercial navigation. The entrance channel has become a weak link in the chain of the system, but the problem has been partially overcome by dredging; however, available dredged material disposal sites in the floodplain are almost at capacity, new ones are scarce, and this type of disposal is environmentally undesirable. Under the currently recommended plan, a 600- by 110-foot lock and hinged-crest gate dam would be constructed within the White River Entrance Channel near mile 0.6. The weir would be a concrete overflow structure with crest elevation at 102 feet National Geodetic Vertical Datum (NGVD) and hinged-crest gates that can be raised in periods of low stages to create a pool to elevation 115 feet NGVD. When Mississippi River stages are at or above elevation 120 feet NGVD, the gates would be in the lowered position, allowing navigation passes over the weir. The crest elevation of the weir with the gates down is at elevation 102 feet NGVD and at 115 feet NGVD when the gate is raised. This lower elevation allows tows to pass over the dam 77 percent of the time under present conditions and 64 percent of the time during estimated future conditions. The estimated first cost of the project is $163.5 million based on October 1989 prices; annual economic costs for a 70-year economic life at an interest rate of 8.8 percent are estimated to total $18.4 million. The estimated benefit-cost ratio is 1.11. POSITIVE IMPACTS: Reliability of the navigation system would be reestablished, allowing all intended inbound and outbound traffic to pass through system channels by guaranteeing authorized dimensions during low-water periods. Bank sloughing due to wide fluctuations of water surface elevation would be placed under control. Not only would the navigation problems be solved, but the amount of dredging needed would be eliminated or lessened. Overland access to the site for construction would use existing roads insofar as possible, restricting disturbance of wildlife habitat. Operation and maintenance costs for the system would decline significantly. Annualized economic benefits redounding from the project would be worth $20.5 million. NEGATIVE IMPACTS: Rights-of-way requirements would involve acquisition of 174 acres. Alteration of land uses on this acreage would result in a loss of biological productivity, including productivity associated with riparian wetland.

Preparation date: September 13, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PHASE I 2020 PLAN AND FEASIBILITY STUDY, LOS ANGELES AND LONG BEACH HARBORS, SAN PEDRO BAY, CALIFORNIA. AN - 36392538; 2819 AB - PURPOSE: Dredging and landfilling in San Pedro Bay, California are proposed in association with Phase I of the 2020 Plan to be accomplished through the federal project and individual port projects. The 2020 Plan, which sets forth conceptual plans to guide future port development, is based on the ports' recognition that the demand for shipments of raw and finished goods through terminals associated with the ports of Long Beach and Los Angeles would continue to grow, to more than double by the year 2020, in response to the increasing national population and trade with Pacific Rim countries. The Cargo Handling Operations, Facilities, and Infrastructure Requirements Study for Implementation of Phase I determined that 38 new terminals on approximately 3,000 acres of newly developed or renovated land would be needed by the year 2020. In addition to assessing the ports' 2020 Plan, this document evaluates the dredging of required channels affecting the movement of waterborne commerce in the San Pedro Bay region and determines the extent of federal participation in the planning and construction of harbor improvement projects. In addition to the No Action Alternative (Alternative F), four of the alternatives (alternatives A through D) under consideration would involve creation of 1,389 to 1,625 acres of landfill and dredging of deepwater channels. A fifth alternative (Alternative E) would involve channel dredging only. The four landfill alternatives would include the Pier J and Los Angeles Crude Oil Transshipment Terminal, which were assessed in previous statements. POSITIVE IMPACTS: Port expansion allowed by the 2020 Plan would accommodate increases in maritime cargo through the ports of Long Beach and Los Angeles, which is expected to increase by more than 100 percent by the year 2020. National economic benefits resulting from construction of the federal portion of the project (dredging existing channels) would include transportation cost savings from the use of larger vessels, more efficient use of vessels, reduction in transit time, and lower cargo handling costs. The landfills and navigation channels would also provide space for strategic projects at the Port of Los Angeles, such as the relocation of existing hazardous cargo terminals in accordance with the port's risk management plan and the relocation of the dry bulk terminal (coal/coke). NEGATIVE IMPACTS: Except for local changes in bottom topography, construction-related impacts of the proposed dredge/fill project on the geologic environment would be minimal and could be mitigated to insignificance; however, the geologic environment could significantly impact the cumulative build-out phase of the 2020 Plan. In view of the potential for seismic activity along the Newport-Inglewood structural zone, the San Andreas fault, and the Palos Verdes Hills fault zone, shaking could occur in the harbors during a moderate nearby or large distant earthquake, possibly causing damage to harbor facilities. Existing and proposed landfills would be susceptible to liquefaction during such an event. Releases of pollutants by dredge and landfill equipment would exacerbate violations of air quality standards, and increases in localized turbidity and releases of polluted sediment would affect water quality. Pollutants released into the water column would affect marine biology in the area, and landfills and other structural measures would reduce the extent and alter the nature of bottom habitat in the bay. An historically significant shipwreck and bascule bridge would be affected. As much as 1,625 acres of open water, providing marine habitat and recreational opportunities, would be lost to landfilling. Transportation facilities and utilities in the area would experience additional stress due to increased traffic generated by the project. Pile drivers and other construction equipment would generate excessive noise levels, and the equipment and subsequent landfill areas and terminal facilities would alter area aesthetics significantly.

Preparation date: September 10, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HANSEN DAM MASTER PLAN, LOS ANGELES COUNTY, CALIFORNIA. AN - 36400525; 2775 AB - PURPOSE: The Hansen Dam, which was designed for flood control, was completed in September 1940. Recreation and environmental resource management were subsequently authorized as secondary project purposes. The last master plan addressing recreation and environmental resources was prepared in 1975. An updated plan is needed to guide the orderly development and use of the natural and man-made resources at Hansen Dam basin. The proposed plan includes a 10-acre lake, footprints for potential future lakes of 15 and 70 acres, and land classification as open space and low- and high-intensity recreation. Hansen Dam is located at the confluence of the Big and Little Tujunga washes along the northern edge of the San Fernando Valley. The dam is 10,475 feet long with a crest elevation of 1,087 feet and a maximum height of 97 feet; it is oriented in an east-west direction across Tujunga Wash. Primary project structures other than the dam include an approach channel, spillway, control tower and outlet works, and an outlet channel. The overall basin is approximately 2.7 miles wide and extends north approximately 1.3 miles, sloping generally northward at a grade of approximately two percent. the reservoir covers approximately 1,090 acres at the maximum water surface elevation and 790 acres at the spillway crest elevation. Approximately 1,450 acres of the total 1,463.5 acres of the Hansen Dam project area are leased to the city of Los Angeles for recreation. Approximately 350 acres have been developed for recreational use, including an 18-hole golf course, an equestrian center, a group picnic area, a visitor center, a sports center, parkland, and equestrian and hiking trails. The following criteria were established for designation of land use allocations: (1) environmentally sensitive areas and areas with high sedimentation and flooding risks would be open space areas, limited to development of trails only; (2) areas adjacent to riparian areas, wildlife habitat, and residential areas; areas with high flood risks; and areas with poor access would be designated for low-intensity recreation use; (3) all remaining areas would be designated as high-intensity recreation use; and (4) existing facilities would be designated according to their current use. Approximately 484 acres would be designated as open space, 334 acres as low-intensity recreation areas, and 145 acres as high-intensity recreation areas. POSITIVE IMPACTS: Plan implementation would support the project purposes of flood control and recreation, derive the optimum benefit from recreational resources and optimize competing resources, use environmental resource values in recreational development, integrate proposed development with existing facilities, and provide development criteria for open space and high- and low-intensity recreational use. The proposed 15-acre lake footprint would provide an ""upper'' swimming lake that would drain down gradient via the meandering stream into the potential 70-acre ""lower'' nonmotorized boating and fishing lake. With lake excavation, there is a potential for discovery of new archaeological resources. The visual quality of the area would be enhanced, and the increased number of visitors into the area could bring additional income and commerce to the locality. NEGATIVE IMPACTS: Construction activities would cause some erosion and result in minor landscape reconfiguration. Approximately 150,000 cubic yards of material would be moved for lake construction. Construction activities would also result in minor air pollutant emissions. Increased human activities within recreational areas could result in possible loss of fringe habitat and increased levels of waste that might attract predators. Increased visitation could also adversely impact existing recreational facilities. The extent of open space within the project area would decline. Establishment of the lake would generate large volumes of traffic, which would impact the level of service offered by the streets surrounding the basin. The financial cost for maintenance and security could be passed on to the public.

Steel dowels are normally used to anchor the replacement material to the existing concrete. A number of failures of anchors embedded in polyester resin grout under wet conditions have been reported. Consequently, a study was initiated as part of the Repair, Evaluation, Maintenance and Rehabilitation (REMR) research program to evaluate the effectiveness of selected materials for embedment of anchors in concrete. The effectiveness of neat portland cement grout, epoxy resin, and prepackaged polyester resin and vinylester resin in embedding anchors in hardened concrete was evaluated under a variety of wet and dry installation and curing conditions. It was determined that the reduced tensile capacity of anchors embedded in concrete under submerged conditions with prepackaged polyester resin and vinylester resin cartridges is primarily attributable to the chanor installation procedure. Therefore, an anchor installation procedure that eliminates the problem of resin and water mixing in the drill hole was developed. In this revised installation procedure, a small volume of adhesive was injected into the bottom of the drill hole in bulk form prior to insertion of the adhesive capsule. The injection was easily accomplished with paired plastic cartridges which contained the vinylester resin and a hardener. The cartridges were inserted into a tool similar to a caulking gun which automatically dispensed the proper material proportions through a static mixing tube directly into the drill hole. Once the injection was completed, a prepackaged vinylester resin capsule was inserted in the drill hole prior to anchor insertion, and spinning displaced the remainder of the water. Anchors with 15 in. embedment lengths installed with this revised procedure exhibited essentially the same tensile capacity under dry or submerged conditions. Additional testing should be conducted to determine the long-term performance of vinylester resin under wet, alkaline conditions. Also, creep tests should be conducted to evaluate the effect of sustained loads on anchors installed with the revised procedure.

While remedial seepage control can be achieved with a rigid concrete cutoff wall, deformations of the earth embankment (for example, caused by an increase in reservoir level or seismic loading) can cause the concrete wall to rupture. Therefore, the designer must select materials for construction of cutoff walls that are not only strong and watertight, but also possess stiffness comparable to the surrounding embankment soil. A comprehensive laboratory test program was conducted to examine property ranges of plastic concrete properties which consists of aggregates, cement, water, and bentomite. Unconfined compressive stress-strain-strength data were recorded from tests on 250 standard concrete cylinders which were cast with the bentonite content, cement factor, and curing time varied. Specifically the weight of bentonite was varied from 0-60% of the weight of cement; the cement factor was varied from 230 to 450 lb/cu yd; and curing time was varied from 3 to 660 days. In addition to the unconfined compression test, 45 splitting tensile, six beam flexure, and two high velocity pinhole erosion tests were also conducted. Some triaxial test results indicated that self-weight consolidation of the plastic concrete may increase the undrained strength 10-fold over unconfined samples. At the same time, the strain at failure can be as much as five times greater than that measured during unconfined compression. Based upon the test results, a design procedure for plastic concrete cutoff walls was developed. Particular emphasis was placed on quantifying the relationship between mixture composition and stress-strain-strength behavior to minimize or eliminate the trial and error approach to mixture design commonly used today. The guiding philosophy behind the analyses was to correlate complex and time consuming (expensive) triaxial tests to simple and quick (less expensive) unconfined compression tests. This change will allow designers to estimate triaxial stress-strain-strength parameters from unconfined stress-strain-strength data. In addition, unconfined behavior was examined at ages up to 660 days, a much longer time frame than typical project test programs allow.

Original construction on the lock was completed in 1933. The dam has a total length of 2,294 ft consisting of forty 20-by-40 ft tainter gates and three 20-by-60 ft roller gates. All of the roller gates, but only two of the tainter gates, are currently mechanized. The remaining 38 tainter gates are raised and lowered by traveling hoist cars which roll along the service bridge on crane rails. A single gate adjustment requires a three-man operation and is hazardous and time consuming. The original hoist chains for these gates were of the round link type and were severely corroded and pitted. Chains have broken four or five times since the original construction. A better system for raising and lowering the tainter gates needed to be found. Major rehabilitation of Dam No. 20, which is currently under way, includes mechanizing the 38 unpowered gates and retrofitting the two powered gates. The machinery designer stated with the round link chains but incorporated the use of pocket wheels for hoisting. The round link chain selected for the rehabilitation project is required to be made of a high allow steel (SAE 8620) and heat treated to approximately 300 BHN. The higher hardness of this material improves wear quality. Pocket wheels are usually used on high and low speed hoists such as overhead cranes and on long conveyors in the mining industry. As the name implies, every other link of the chain rides in a pocket as it passes over the wheel which loads the chain in tension and bearing. Pocket wheels are designed with sufficient accuracy to handle and hold a chain to its breaking strength. The main advantage of the pocket wheel and round link chain combination is that no maintenance will be needed after this upgrade. The chain does not need lubrication as is the case with roller chain or wire rope. The chain does not stiffen in corrosive environments, in contrast to roller chain, and it is more durable.

The only method approved by the EPA for mercury analysis under the Clean Water Act is a flameless atomic absorption (AA) method, EPA Method 245.1, more commonly referred to as the Cold Vapor Technique. The procedure uses a 100 mL sample aliquot and attains a 0.2 microgm/L detection limit. The detection limit may be lowered to 0.1 microgm/L by doubling the sample aliquot, but it is not feasible to extend the procedure further without extensive procedure modification. To obtain lower detection limits, another technique has been developed where mercury is reduced to the elemental state with stannous chloride and purged from the sample with nitrogen. Volatile mercury is collected on gold-plated quartz chips contained in a quartz column. The columns are thermally desorbed in a stream of nitrogen and the resultant mercury vapor is analyzed by Cold Vapor AA. The procedure lists a realistic detection limit of 0.2 nanogm of mercury using a Class 100 clean room for analysis. Another procedure under investigation for determining these lower detection limits is a modification of a procedure using a Gold Film Mercury Vapor Analyzer, called the Jerome 511 Mercury Analyzer. This 'Analyzer' has a detection limit of 1 nanogm of mercury with a 10 mL sample size. In theory, a 100 mL sample aliquot should produce a detection limit of 0.01 microgm/L which would meet the recommendations of the water quality criteria.

AN - 36384340; 2755 AB - PURPOSE: Installation and operation of a second Relocatable Over-the-Horizon Radar (ROTHR) System on Amchitka Island, Alaska is proposed, along with improvements to support facilities for the first system on the island. Amchitka Island is managed by the U.S. Fish and Wildlife Service as part of the Alaska Maritime National Wildlife Refuge. A portion of the island has been designated as wilderness. The Navy is required to provide surveillance to detect and track aircraft and ships in the northwest Pacific to support maritime tactical forces. Construction of the first ROTHR on Amchitka Island was completed in December 1988. That ROTHR system will provide surveillance for one-half of the required area, while the addition of the proposed project would complete the Navy's wide-area surveillance requirement. The project would be implemented over a three-year period in three phases: remodeling and new construction at the Base Camp facilities, including construction of water and sewer systems; replacement of an existing supply pier, repair of two existing water supply dams, and creation of a new water supply dam near the pier; and construction of one new ROTHR transmitter, one new ROTHR receiver, and improvements to the existing transmitter and receiver sites. The electronic installations would consist of antenna towers and arrays, ground screens, and support facilities. The new transmitter would be located approximately 1.33 miles southeast of the existing transmitter site at elevation 690 feet. Required cut would be 427,000 cubic yards and required fill would be 194,000 cubic yards. Additional earthwork for the antenna pad would require 950 cubic yards of cut and 37,000 cubic yards of fill. Approximately 0.75 mile of new access road would be required to link Infantry Road to the transmitter facility. Facilities would include a system operation and maintenance building, a septic tank system, an antenna array, transmitter vans, arctic corridors, fencing, and utility lines. Electrical power would be supplied from the power plant at the existing transmitter site by underground cable in the roadway. Fiber optics and communications systems would be interconnected. Water would be provided from North Camp via the same trench as the power and communication lines. The proposed receiver site would be located 3.2 miles east of the Base Camp at elevation 200 feet. Required cut would be 2.37 million cubic yards; required fill would be 1.9 million cubic yards. Facilities would be similar to those at the transmitter site, without fencing. Minor realignment of Engineer Road would be required. POSITIVE IMPACTS: Acting as an early warning system, the radar array and associated facilities would boost national and international defense efforts. The facilities would complete the provision of surveillance capabilities to detect and track aircraft and ships in the northwest Pacific in order to support maritime tactical forces. NEGATIVE IMPACTS: Some impacts to wetlands and surface water would result from developments associated with the transmitter and receiver sites and dock facilities. Wetland and lake areas impacted would range from 189 to 196 acres for all phases of the total project. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

AN - 36410441; 2825 AB - PURPOSE: Designation of a permanent site for ocean disposal of material dredged from channels within the greater Miami area of Florida is proposed. The preferred alternative would be to designate for permanent use the currently designated interim site, an area of approximately one square nautical mile. The site has the following coordinates: 25 degrees, 45 minutes, 30 seconds north latitude (N), 80 degrees, 3 minutes, 54 seconds west longitude (W); 25 degrees, 45 minutes, 30 seconds N, 80 degrees, 2 minutes, 50 seconds W; 25 degrees, 44 minutes, 30 seconds N, 80 degrees, 2 minutes, 50 seconds W; 25 degrees, 44 minutes, 30 seconds N, 80 degrees, 3 minutes, 54 seconds W. The site is centered at 25 degrees, 45 minutes N, 80 degrees, 3 minutes, 22 seconds W. The site is situated on the continental slope. Depths at the site range from approximately 427 to 785 feet. The depth at the center is approximately 625 feet. The average declivity of the slope at the site is approximately 325 feet per nautical mile. A 1986 survey of the site found surficial sediments, comprised primarily of fine sands and coarse silt in the vicinity of the proposed site. Sediments are well-sorted and relatively uniform throughout the area. POSITIVE IMPACTS: Availability of an ocean dumping site in an area where sufficient upland sites are unavailable would provide for an environmentally sound, economically feasible means of disposing of materials dredged from Miami channels. As a result, the navigability of area channels would be maintained for economic use as well as recreational purposes. NEGATIVE IMPACTS: Disposal operations would result in water quality perturbations, including turbidity plumes, the release of chemicals, and lowered dissolved oxygen concentrations. Site benthos would be smothered, and site bathymetry and sediment composition would be altered. Use of the site would result in irretrievable loss of sand that could be used for fill.

AN - 15224077; 2831 AB - PURPOSE: Modification or replacement of the existing holding and loading facilities for the downstream passage of juvenile fish at McNary Dam on the Columbia River near Umatilla, Oregon is proposed in this supplement to the final environmental impact statement of September 1976 on construction of the McNary Lock and Dam. The McNary site is located near Umatilla, Oregon at River Mile 292 on the Columbia River. The reservoir formed by the dam, known as Lake Wallula, extends 64 miles upstream of the dam. The new facility would involve modification of the fish collection channel, replacement of the barge-loading facility, enlargement or replacement of the raceways for holding fish, construction of laboratory and office buildings, and installation of conveyance lines between the various components of the system. The preferred project plan would involve construction of completely new facilities for conveyance, handling, and laboratory work in Spillway Park on the south shoreline of the existing tailrace on the Oregon shore. The site lies approximately 500 feet downstream (west) of the powerhouse and downstream from an adult fish attraction water pumping station and the south shore ice and trash sluiceway exit. Fish exiting the south end of the collection channel of the powerhouse would be transported to a separator in the holding facility by means of a 900-foot elevated open channel flume. The flume transport would exit the ice trash sluiceway, pass through the assembly bay over the powerhouse control room, and around the bridge crane and tailrace deck gantry crane. From the separator, adult fish would be returned to the river and juvenile fish would be separated according to size. Juvenile fish would be transported by a 10-inch-diameter polyvinylchloride pipe from the holding facility to the dock loading platform located approximately 150 feet offshore. Bypassed juvenile fish would be discharged approximately 400 feet downstream of the barge loading dock. Approximately 49,000 cubic yards of random fill and riprap would be placed along the shoreline of the existing tailrace channel to provide approximately 20 to 60 feet of additional width at the site. POSITIVE IMPACTS: Improvement of the fishery enhancement facilities would provide increased capacity and reduce mortality in the collection and bypass system. This would accommodate the increased numbers of migrating juvenile fish at McNary Dam that would otherwise exceed the capacity of the fishery enhancement facilities. Capacity requirements have increased from 4.0 million juvenile fish per year when the facility was first installed to 11.2 million fish in 1988 and are expected to increase by 20 million fish annually by 1995. NEGATIVE IMPACTS: Less than one acre of Spillway Park would be displaced by project facilities. Facilities could hamper barge-tow operations, and two plans would result in spillway spray affecting workers loading barges. Approximately one acre of wildlife habitat would be disturbed, and some excavation could be necessary. Minimal river disruption or displacement would result from dock construction or installation of a fish bypass pipe. Some shore area and, possibly, shore area and water restrictions could result.

Preparation date: August 29, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RIO GRANDE FLOODWAY, SAN ACACIA TO BOSQUE DEL APACHE UNIT, SOCORRO COUNTY, NEW MEXICO (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MAY 1974). AN - 36405725; 2830 AB - PURPOSE: Implementation of flood control for communities within the Rio Grande floodplain in Socorro County, New Mexico is proposed. This draft supplement to the final environmental impact statement of May 1974 on the construction of two dry reservoirs for flood and sediment control addresses alternative plans developed to provide higher levels of flood protection to floodplain communities, development, and wildlife habitat in the area extending from the San Acacia Diversion Dam to the headwaters of Elephant Butte Reservoir. The recommended alternative would involve reconstruction of 55 miles of levee parallel to the west bank of the Rio Grande between the river and the low-flow channel. The initial 2,200 feet of the levee would divert from the existing alignment to run immediately west of the Socorro Main Canal, and the opposite end of the levee would be extended 2,500 feet to the west to tie into the bordering terrace, which is a tie-back levee. Gate conduits would carry flows in the conveyance channel through the levee. The design capacity of the reconstructed levee would be 51,000 cubic feet per second (cfs) at the diversion dam and decrease to 39,000 cfs at the lower end. Along most of its length, the levee would have 1 vertical on 2.5 horizontal side slopes; however, the lower 20.4 miles of levee (below the conveyance channel bridge midway through Bosque del Apache National Wildlife Refuge) would have 1 vertical on 3.0 horizontal side slopes. The crest width would be approximately 16 feet while the average base width would be 73 feet. Kellner jetties and seepage drains would be provided as necessary. The project would result in the generation of 1.249 million cubic yards of surplus earth, which would be disposed via layering on the side slopes of the construction levee, widening riverbanks in areas where the river is adjacent to the levee, and stabilizing with jetty jacks and riparian vegetation, filling borrow areas, and/or upland dumping. Additional lands required for the project would be obtained via easement. Recreational facilities could be included in the project design. The estimated cost of the project is $47.0 million at 1989 prices, and the benefit-cost ratio is 2.2. POSITIVE IMPACTS: The project would provide protection to life and property against a 100-year flood in the Socorro area, to the low-flow conveyance channel, and to Bosque del Apache National Wildlife Refuge. Sedimentation of the low-flow channel and receiving waters would also decline. The project would provide the possibility of developing wetlands from borrow areas and could provide better access for the management of existing and created wetlands. The net worth of average annual benefits accruing from the project would be $10.9 million. NEGATIVE IMPACTS: Approximately 171 acres of monotypic salt cedar, early growth, and sparse vegetation could be removed and replaced with native riparian vegetation and wetlands. A maximum of 46 acres of predominantly salt cedar could be permanently removed and compensated for on the Bosque del Apache National Wildlife Refuge.

Preparation date: August 21, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CENTRAL ARTERY (INTERSTATE 93)/THIRD HARBOR TUNNEL (INTERSTATE 90) PROJECT, BOSTON, MASSACHUSETTS (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1985). AN - 36410310; 2805 AB - PURPOSE: Extension of Interstate 90 (I-90) (Massachusetts Turnpike) from its terminus at the Central Artery in Boston across Boston Harbor to a new terminus in East Boston, Massachusetts is proposed. The project, which would be known as the Third Harbor Tunnel, would be located entirely in the city of Boston in Suffolk County. The one-way tunnel in Fort Point Channel would carry all northbound traffic to a widened and depressed Central Artery. This final supplement to the final environmental impact statement of August 1985 addresses construction of the South Boston Haul Road, an early construction traffic mitigation measure for the Central Artery (I-93)/Third Harbor Tunnel (I-90) project. The Haul Road would be a two-lane, limited-access truck route for construction-related vehicles, commercial truck traffic, and empty buses travelling between the Massachusetts Bay Transportation Authority (MBTA) Cabot Yard bus facility and service routes. The Haul Road would be built substantially within an existing depressed railroad rights-of-way. The alignment would connect Dorchester Avenue and Congress Street with access to the Massport Haul Road via Congress and B streets. Beginning on the west side of Dorchester Avenue, the Haul Road would traverse the existing MBTA Cabot Yard parking lot to gain access to the existing depressed freight railroad rights-of-way of the Consolidated Rail Corporation (Conrail). The roadway would follow the west side of the tracks for its full length, approximately 1.1 miles, to a terminus at existing Congress Street. The project would also include installation of new drainage and railroad facilities. The drainage facilities would direct stormwater through a new 16-inch flow-force main and a new 24-inch-high flow-force main under Dorchester Avenue. Both would run to a new 42-inch gravity storm drain to be located west of Dorchester Avenue and south of West Fourth Street to a new outlet structure at the southern end of Upper Fort Point Channel. Other project actions would include the replacement of railroad tracks, relocation of a freight loading dock, and construction of other railroad facilities. POSITIVE IMPACTS: Construction of the Haul Road would maintain surface street traffic patterns during the extended construction period of the Artery /Tunnel project. Completion of the Haul Road at the earliest possible date would be important to the success of the Artery /Tunnel project and the improvement of existing traffic circulation conditions. Truck traffic on South Boston streets would decline substantially, significantly improving circulation within this area of the city. NEGATIVE IMPACTS: The Haul Road would displace 228 surface parking spaces on two public properties and one private property. Approximately 18 acres of land presently owned by four parties would be permanently acquired. An additional eight acres would be acquired via easements for construction period and drainage easements. Rail track and utility relocations would be necessary, and one Conrail loading dock and an MBTA office trailer would be relocated. Truck traffic on the Haul Road during peak hours in 1993 would result in higher than existing noise levels on surface streets in the corridor. Truck-generated noise levels within 150 feet of the Conrail cut would exceed federal standards for some land uses. Approximately 51,000 cubic yards of material, including some hazardous materials, would be excavated during the project. The Boston Crown Glassworks archaeological site could be affected.

Preparation date: August 17, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SPIRIT MOUNTAIN, FORT MOJAVE INDIAN RESERVATION, CLARK COUNTY, NEVADA AND SAN BERNARDINO COUNTY, CALIFORNIA. AN - 36405510; 2812 AB - PURPOSE: Development of a destination resort and a planned residential community on approximately 4,000 acres of land in the Fort Mojave Indian Reservation of Clark County, Nevada and San Bernardino County, California is proposed. The reservation is located approximately 125 miles south of Las Vegas and comprises an area of 5,582 acres in Clark County, Nevada; 12,663 acres in San Bernardino County, California; and 23,669 acres in Mohave County, Arizona. The reservation is located in Mohave Valley and bordered by the Black, Dead, and Newberry Mountain ranges. The Mojave Indian Tribe would lease two sites within this planned community to two separate developers who would assist the tribe in specific planning, construction, financing, marketing, and management of these sites. The lease sites are located in Clark County, Nevada and San Bernardino County, California. The Movada Group proposes to lease approximately 1,000 acres of Indian trust land for a period of approximately 75 years under the terms and conditions of the lease agreement. The American Land Development Corporation proposes to lease approximately 1,200 acres of Indian trust land for a period of 90 years under the terms and conditions of the lease agreement. The Movada Group would include a Town Center, three hotel/casinos with 2,000 rooms, 2,007 residential units, 30 acres of recreational vehicle spaces, 18-hole and 9-hole executive golf courses and associated facilities, a 75-acre lake, mixed office/retail uses, public facilities, a school, a neighborhood park, and other open spaces. The American Land Development Corporation would develop a residential complex adjacent to the Movada Group development. This development would include 10,280 residential units, an 18-hole golf course with associated facilities, a community park with open-air amphitheater, neighborhood parks, mixed office/retail uses, and a school. POSITIVE IMPACTS: Development of the land would provide economic, social, and recreational benefits to current and future residents. Extensive economic benefits, including numerous jobs, would be provided to members of the Mojave Tribe, while social and recreational benefits would redound to tribe members and nontribal persons. NEGATIVE IMPACTS: Consumptive uses would require approximately 3,500 acre-feet of water annually to meet the needs of the project at build-out; this water would be removed from the Colorado River's near-surface aquifer and would not be available for other tribal activities or downstream uses. Approximately 1,000 to 1,200 acres of vegetation and associated wildlife habitat would be affected. Growth in the local population would increase pressure on air quality, transportation facilities, housing, school resources, and other social services. Facilities associated with the development would impinge visually on area aesthetics.

AN - 36404588; 2799 AB - PURPOSE: Construction and operation of test facilities and testing the Advanced Solid Rocket Motor (ASRM), which will replace the motors currently used to launch the Space Shuttle, are proposed. The project site would be located at the John C. Stennis Space Center in Hancock County, Mississippi. The Space Center is located within 12 miles of the Gulf Coast and includes a NASA fee ownership area and an acoustical buffer zone. The fee area, where all NASA-approved institutional and industrial development takes place, occupies approximately 22 square miles. The acoustical buffer zone consists of 200 square miles extending outward 5 miles from the fee area perimeter. The ASRM project facilities would be located in the eastern portion of the fee area. Facilities to be constructed would include a lateral access road, a construction access road, an engineering operations building, a test control center, an equipment storage facility, a barge/dock facility on the existing canal, a test stand, a heavy duty transporter road to move the ASRM from the barge dock to the test stand, a deflection ramp, and a catch basin to collect stormwater runoff. A fire safety zone would be cleared around the test stand. Project operation may include testing up to four motors per year. Construction is scheduled to begin in late 1990, with initial testing scheduled in mid-1993. The test stand location is approximately 6.5 miles from the nearest community outside the Stennis Space Center and approximately 2.0 miles from most of the space center's workforce. Each test would last approximately two minutes and would emit combustion products that include aluminum oxide, hydrogen chloride gas, water vapor, carbon dioxide, aluminum chloride, and other constituents. Hot rocket exhaust would extend out horizontally from the test stand before the exhaust would lose energy and begin to rise to an altitude of more than 10,000 feet at the plume's centerline. POSITIVE IMPACTS: Testing of the ASRMs would greatly improve their reliability, flight safety, and performance. Federal expenditures on the Space Shuttle would be reduced, and privatization of the program would be encouraged. Employment associated with the development and operation of ASRM facilities would provide a boost to local economies. Minimum possible impacts to wetlands would result, and where impacts cannot be avoided, mitigation would be provided to return them to their natural state. Potential exposure to exhaust products should not cause any adverse effects on humans. NEGATIVE IMPACTS: Small amounts of wetlands could be filled and wildlife habitat displaced. Test firing the motors and disposing of waste propellant by burning would release pollutants into the ambient atmosphere; surface water, vegetation, and wildlife in the safety clear zone would be minimally affected by these localized air pollutants. Areas adjacent to the test sites would be exposed to high noise levels during test periods, which would occur two to four times per year.

Preparation date: August 10, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GEORGE P. COLEMAN BRIDGE YORK RIVER CROSSING STUDY, YORK AND GLOUCESTER COUNTIES, VIRGINIA. AN - 36392627; 2808 AB - PURPOSE: Construction of the George P. Coleman Bridge across the York River in Virginia is proposed to improve the connection between York and Gloucester counties. The study area for the project includes portions of Gloucester, York, and James City counties and a 20-mile section of the York River. The existing bridge is a two-lane, 0.71-mile facility, with double-swing spans, crossing the York River in southeastern Virginia at Yorktown. It is the only York River crossing south of West Point, a community 30 miles upriver. The proposed action would involve widening the existing bridge from a two-lane to a four-lane facility, with shoulders and a median barrier. The alignment would begin near the intersection of Route 17 and Route 1012 (Alexander Hamilton Boulevard) in York County. It would follow Route 17 across the existing Coleman Bridge and end near the entrance to Tindalls Point Park in Gloucester County, a distance of 1.4 miles. The roadway expansion would be symmetrical around the centerline of the existing bridge. Existing two-lane approach roads would also be widened to match the bridge widening. The estimated cost of the project is $72.0 million. POSITIVE IMPACTS: Construction of the proposed project would expand the vehicular capacity for crossing the York River in the vicinity of the existing George P. Coleman Bridge, thereby reducing current traffic congestion and delays during peak periods; match the approach road capacity of four lanes, thereby eliminating temporary backups and merging delays; minimize mechanical failure of the swing span, thereby reducing maintenance and temporary congestion; and facilitate the movement of emergency and rescue equipment. Travel between the peninsulas is critical to the continued social and economic health of the region, which includes the rural outlying counties of King and Queen, Middlesex, and Mathews, and the urbanized areas of James City, Hampton, Newport News, and Norfolk. No families or businesses would be displaced. NEGATIVE IMPACTS: A portion of the local property tax bases would be lost. Approximately 11 residences, 4 institutions, and 16 acres of parkland would experience increased noise levels. Approximately 0.1 acre of wetlands and recreational lands would be impacted during construction. Numerous historical and archaeological sites could be damaged, and the existing Coleman Bridge, which is eligible for inclusion on the National Register of Historic Places, would be affected.

AN - 36392577; 2758 AB - PURPOSE: Closure of the Presidio of San Francisco Army installation, relocation to other installations, and disposition of a 36-acre parcel in the southern portion of the Presidio in San Francisco, California are proposed. The Presidio is located on the northwestern tip of the San Francisco peninsula. The base, which occupies 1,270 acres, has a history of continual military presence since its establishment in 1776 by the Spanish. Present primary activities include provision of logistical and administrative support to active and reserve component units in northern California and Nevada, medical treatment, and medical research. The majority of the Presidio (approximately 1,234 acres), would be transferred to the control of the Department of the Interior for use as part of the National Park Service's Golden Gate National Recreation Area. The remaining 36-acre parcel proposed for disposal includes the former Public Health Service Hospital Complex. The Presidio employs approximately 5,600 persons, including some 2,200 military personnel. There are 890 buildings on the post, containing 6.7 million square feet of space. Approximately 3,400 Army and civilian personnel positions would be relocated from the Presidio. Major unit relocations include the Sixth Army Headquarters to Fort Carson, Colorado; Letterman Army Institute of Research to Fort Detrick, Maryland; and Logistics Control Activity to Letterkenny Army Depot near Chambersburg, Pennsylvania. Medical personnel would be assigned to several bases, primarily Fort Lewis, Washington; Fort Gordon, Georgia; Fort Shafter, Hawaii; Fort Bragg, North Carolina; and Walter Reed Army Medical Center, District of Columbia. The Letterman Army Medical Center would be inactivated. Tenants not slated for relocation to leased facilities, but who nonetheless perform locally oriented missions, would be relocated to other military installations in the San Francisco Bay or Sacramento areas. POSITIVE IMPACTS: Without hindering the military mission of the Army, closure of the base would decrease budgetary expenditures and increase overall efficiency of Army base activities. The termination of waste production due to base military activities would contribute to the longevity of the local landfills. NEGATIVE IMPACTS: Base closure would increase medical treatment costs for retired Army personnel and their dependents living in the San Francisco Bay area. Risk of earthquake damage to property and personal injury for personnel relocated from San Francisco to the Oakland Army Base would also increase. Future uses of the 36-acre parcel to be disposed could result in its degradation. Historic sites could be affected by future land uses that involve demolition. Increases in receiving-base populations due to relocation of personnel positions from the Presidio would range from less than 0.1 percent to nearly 7.0 percent, so major socioeconomic and vehicular traffic impacts would not generally be expected to occur.

AN - 36405163; 2822 AB - PURPOSE: Implementation of a plan to improve water deliveries to the Everglades National Park in southern Florida is proposed. A large area outside the park's boundaries affects flows available to the park due to the sensitive hydrologic interconnection of all components of the Everglades. The study area includes the Everglades National Park, East Everglades, and two parts of Water Conservation Area Number 3. The area is located in Broward and Dade counties, west and southwest of Miami. This report addresses the Shark River Slough portion of water deliveries from the Central and Southern Florida Project to the park. The South Florida Water Management District developed a computer model to simulate the effects of different hydrometeorological conditions within the Central and Southern Florida Project boundaries. Based on a review of alternatives developed using the output of this model, a recommended plan was selected. The plan, which is a rain-driven water delivery plan, would involve construction of three gated culvert structures, three gated concrete headwall structures, and two spillway structures. The plan could also involve relocation of structure 334, raising a portion of the Tamiami Trail (U.S. 41), and degrading the existing Levee 67 extension and filling the borrow canal. The plan would provide flood mitigation in residential areas through construction of two pump stations and a double levee and canal around the western and northern reaches of the residential area. In addition, a nearby Miccosukee Indian Camp and a recreational area along Levee 29 would be raised to prevent flood damages from occurring due to implementation of the project. The project's impact on the adjacent agricultural area of the East Everglades and on the endangered snail kite would be monitored. The estimated cost of the project is $72.7 million, based on July 1990 price levels; this cost covers construction of facilities, acquisition of land for rights-of-way, and implementation of the monitoring programs. POSITIVE IMPACTS: Corrective actions under the project would reduce water releases to the Shark River Slough gated structures, especially during normal dry season recession periods; restore flow distribution across the entire width of the slough, which is the natural flow-way into the park; restore hydroperiods in the eastern portion of the historic slough basin; allow volume and timing deliveries to fluctuate as they did historically in response to rainfall and antecedent water conditions in the southern Everglades; maintain downstream slough water levels at preproject levels; and maintain water quality so that resource degradation would not occur. NEGATIVE IMPACTS: Structural features of the project would affect wetlands and contrast aesthetically with their natural surroundings. Nutrients, particularly phosphorous, could enter the Everglades during floodwater pumpage. The project could have effects on social and economic activities of the Miccosukee Indians.

AN - 36400878; 2829 AB - PURPOSE: Implementation of a beach nourishment project at Great Egg Harbor Inlet and Peck Beach in Ocean City, New Jersey is proposed. The beach project site, which extends nine miles between Longport and Corson's Inlet, is located in Atlantic and Cape May counties. Beach erosion is particularly pronounced between 5th and 18th streets and is serious as far north as Surf Road and as far south as 23rd Street. The preferred plan would result in a minimum 100-foot-wide berm with an elevation of eight feet above the National Geodetic Vertical Datum (NGVD) that would extend from the Surf Road groin to 34th Street in the project area. The berm would parallel the alignment of the existing bulkhead, boardwalk, or dunes. The foreshore design slope would be 30 horizontal to 1 vertical, and the stabilized underwater slope would be 50 horizontal to 1 vertical. Initial beach nourishment would require 4.1 million cubic yards of material and would extend over an 11-month period. Outfalls of 38 storm drains would be extended to points beyond the design slope. Periodic nourishment would occur on a three-year basis for the 50-year life of the project. Each periodic nourishment episode would require 1.1 million cubic yards. The borrow site for both the initial placement and the subsequent periodic nourishment activities would be the ebb shoal of the Great Egg Harbor Inlet. An area extending over 290 acres at the shoal would be designated for potential excavation to 26 feet below the NGVD. The borrow area is approximately 5,000 feet offshore, southeast of the Gardens section of Ocean City. An environmental impact statement that is related to this project was prepared in September 1970, but it was of a more general nature. A more specific draft environmental impact statement was issued in September 1976, but was never finalized. This final supplemental environmental impact statement provides a more detailed analysis of the status and impacts of the currently proposed project. POSITIVE IMPACTS: Nourishment of the beach at Ocean City would enhance one of New Jersey's prime shore recreational centers; the beach along the boardwalk is one of the main attractions in the area. The risk of property damage due to storm surges would decline significantly, maintaining property values in shoreline areas of Ocean City. NEGATIVE IMPACTS: Removal of material from the shoal and placing it on the nourishment site would destroy benthos. Benthic community standing stocks would be decreased during dredging and disposition of beach nourishment.

Preparation date: August 2, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - N.E. 181ST AVENUE TO SANDY RIVER, COLUMBIA RIVER HIGHWAY (I-84), MULTNOMAH COUNTY, OREGON (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1989). AN - 36392698; 2806 AB - PURPOSE: Widening of Interstate 84 (I-84) between the N.E. 181st Avenue interchange and the Troutdale interchange from four to six lanes in Multnomah County, Oregon is proposed. The project would extend 4.7 miles within the city limits of Fairview, Wood Village, Gresham, and Troutdale. All interchanges within the project termini would be modified. The partial interchange connecting I-84 with Sandy Boulevard west of N.E. 223rd Avenue would be replaced by a full interchange at N.E. 207th Avenue, with access to Sandy Boulevard. A new roadway would be constructed from the interchange ramps to Sandy Boulevard. The interchange at N.E. 238th Avenue would be rebuilt as a standard diamond interchange. The Troutdale interchange would be modified to provide adequate vertical clearance and improve ramp terminal intersections. A bicycle path would be constructed within the highway rights-of-way, and grade separations would be provided at major cross streets. Graham Road would be realigned slightly, and the two bridges carrying I-84 over Graham Road would be replaced. The intersections between the ramps and Marine Drive and Graham Road would be changed to include traffic signals and channelization. In order to mitigate wetlands impacts, 1.5 acres of palustrine wetlands would be created from existing uplands; these wetlands would constitute an extension of an existing marsh. Special features would be added to the project design to contain hazardous waste spills due to the existence of a public water well field northwest of the project corridor. This draft supplement to the draft environmental impact statement (DEIS) of August 1989 covers impacts associated with the construction of a folded diamond interchange at N.E. 207th Avenue and construction of a five-lane arterial from Sandy Boulevard to Halsey Street. The estimated cost of the project, as proposed in the DEIS, was $53.7 million for construction and $9.3 million for rights-of-way acquisition. Changes proposed in this supplement are expected to add approximately $2.3 million to the construction cost of the overall widening project. POSITIVE IMPACTS: Expansion of the freeway's capacity would improve traffic flow and decrease accident potential and operating costs. Federal Interstate and Defense Highway standards would be met. The N.E. 207th Avenue interchange would serve traffic from all directions, unlike the existing interchange that only serves traffic to and from the east. An at-grade railroad crossing on N.E. 238th Avenue would be replaced by a grade separation. Significant noise impacts would be reduced for numerous residences and one motel. NEGATIVE IMPACTS: Rights-of-way development for construction of the portion of N.E. 207th Avenue under consideration and the interchange at N.E. 207th Avenue would result in the filling of 0.7 acre of wetlands and displacement of 10 mobile homes and 5 permanent residences. There would be a potential for hazardous waste material spills from vehicles using the freeway.

Previous studies for the Dallas Floodway system had indicated that future development would reduce the freeboard for the Standard Project Flood (the design flood) for the levees of the Dallas Floodway. Concern about cumulative effects of continued floodplain development and loss of valley storage were primary factors in the decision to conduct a Regional Environmental Impact Study (REIS) for the upper Trinity River basin to develop criteria for making decisions under the Section 404 program. The REIS considered and displayed hydrology, hydraulic, environmental and economic impacts. HEC-1, LRD (Little Rock District hydraulics computer program), and NUDALLAS (Fort Worth District hydrology computer program) were utilized to evaluate various policy alternatives for mainstem floodplain development. Cumulative impacts of valley storage loss with various development scenarios were shown to be significant. Valley storage loss criteria wereadopted for Section 404 permit decisions to limit cumulative impacts. Education of the local cities to the risks of various types of development resulted in their support of our Section 404 permit progra and their voluntary support of a regulatory program for the part of the floodplain over which they have jurisdiction and the Corps does not. Problems which were indicated in the REIS caused the North Central Texas Council of Governments (NCTCOG) with 9 member cities and 3counties to pursue a reconnaissance planning study for the Upper Trinity River.

Reallocation of 50,000 acre-feet of storage space was accomplished at this project under the discretionary authority of the Chief of Engineers in August 1983. Also, reserved in this project is 22,600 acre-feet of storage space for use by the City of Sherman, Texas, authorized by Public Law 85-146. The 1985 study was documented in a report entitled "Letter Report, Denison Dam (Lake Texoma), North Texas Municipal Water District" (Tulsa District Corps of Engineers, 1985). This report addressed the impacts of the total reallocation (150,000 acre-feet) on the project to ascertain if the last added increment of water supply seriously affected the purpose for which the project was constructed or if major structural or operational changes would be necessary. A significant change in the project could only be approved by Congress (Sec. 301(d) of Public Law 85-500, as amended).

The Olmsted Project will replace existing Locks and Dams 52 and 53 with a single project located 1.8 miles downstream of Locks and Dam 53 at Ohio River Mile (ORM) 964.4, near Olmsted, Illinois. The Olmsted Project is proposed to be operated as a "hinged pool." The hinge point for project operations is at Paducah, Kentucky located 30 miles upstream of the dam. The proposed hinged pool operation will require a more sophisticated flow regulation and pool control system than the "stair-step" operation now in use on the Ohio River Navigation system. This paper addresses the need for an unsteady flow regulation model for the proposed hinged pool operation at the Olmsted Project. A proposed unsteady flow regulation model is presented.

The American River has experienced several large flood events within the past 35 years which strained the operation of the existing flood control system. As a result, an effort was made to update the hydrology of the American River and to evaluate both the existing flood control system and measures to upgrade the system. This paper briefly discusses the study approach and analysis.

The Corps has embraced the utilization of computer-aided design and drafting (CADD) in an attempt to standardize operations in the construction and design arenas. Implementation of Geographic Information Systems (GIS) has been evolving within the Corps over the last 15 years in the attempt to enhance basin-wide planning studies, environmental impact assessments, and resource master planning. The CADD and GIS technologies are highly compatible, with the long-range goal being to create a corporate data base (CDB) structure, by mutual and timely implementation of both. A CADD system uses map-level functions to portray features related to design and drafting operations. In the simplest sense, CADD can mean the automation of drafting operations in two- or three-dimensions. Automation of design operations are also afforded using civil and hydraulic engineering software packages. A computer mapping system (automated mapping facilities management (AM/FM)) and certain land information systems (LIS) provide similar functionalities, such as display of the geographic locations of features for the drafting and production of maps only. CADD, AM/FM, or LIS in the simplest sense, do not provide innate information on the relationships with adjacent features (coincidence, proximity, etc.) nor any descriptive data about the features themselves. Products from these systems, hence, do not usually have native intelligence.

The primary purpose of the model is to evaluate alternative plans of regulation from both a hydrologic and an economic perspective. The model is a period of record type program with a routing interval of one day. Residual flood damage computations are an integral part of the model and are based on sequential analysis of the simulated daily hydrographs. These daily hydrographs do not of course define peak discharges with sufficient accuracy at all locations. The recent Arkansas River Reservoir System Studies (reference 4) conducted for the Arkansas River Basin Feasibility Study required the evaluation of alternative system regulation plans. The flood damage calculations were to be performed external to the model by traditional methods which require peak discharge frequency estimates up to the Standard Project Flood (SPF) order of magnitude throughout the basin. Since SWD reservoir system regulation studies must, for practical reasons, be performed using the existing daily model, it was required that a procedure be developed to estimate peak discharges on the basis of simulated daily regulated flows.

We had neither severe droughts nor major floods. As a result of this very moderate weather pattern, the public came to expect that Corps projects would generally meet all project purposes with only a minor impacts on any one purpose. During the 1980's we have experienced much larger deviations from this moderate weather, including the worst drought in the sixty-five year record. We realized a thorough review of our water management practices was appropriate. This paper gives an overview of that review relative to drought contingency planning and management for project purposes. Severalkey issues have come to light as a result of our own review and the review of others such as the General Accounting Office (GAO). Some of these issues deal with the time required to appropriately study and develop drought contingency plans. Others deal with the project purposes and our authority to manage for those not specially listed in the authorizing legislation. Other issues have to do with management for a purpose that was specifically authorized but has no costallocated to it.

See Figure 1 (Heltzel, 1989). A deep draft project is maintained from the edge of the Continental Shelf into Southwest Pass, a major distributary of the Mississippi River. The entrance to Southwest Pass from the Gulf of Mexico is guarded by stone jetties whichconverge from a width of 3600 feet at the shoreline to an opening of about 1500 feet at the ends 3.5 miles offshore. The modeling effort I describe here was intended to find suitable alternatives to an expensive rehabilitation program for the Inner Bulkhead, a feature of the jetty reach of the Pass depicted by a dashed line on Figure 5. The Inner Bulkhead (Corps of Engineers, 1984) was intended to rectify the hydraulic problem created by the jetties having been constructed at a distance too far apart in 1904. Over time the bulkheads settled out of site into the mud line and ceased to provide the required confinement for efficient sediment transport in the reach. The shoaling problem has worsened with time as the project depth has changed from 30 feet to 45 feet in 5-foot increments between 1930 and 1988.

Through the State Water Plan, PennDER has identified the general magnitude of these consumptive water supply needs, and is in the process of determining feasible alternative solutions to these problems. Before PennDER pursues the development of new reservoirs, the Pittsburgh District of the U.S. Army Corps of Engineers, under Section 22 (P.L 93-251), was asked to examine the potential of its existing reservoirs for meeting all or a portion of theses needs. The potential of these reservoirs, by either reauthorization of storage or modification of the structure to add additional storage, was considered, with the initial effort by the Pittsburgh District directed to the Allegheny Reservoir in 1978. The Allegheny Reservoir study completed in 1980 was followed by studies of the Youghiogheny River Lake (1983), the East Branch Clarion River Lake (1984), and the Woodcock Creek Lake (1988). This paper will focus on two of these studies, i.e. Allegheny Reservoir where excess storage for water supply appears to be available, and Youghiogheny River Lake where no excess storage appears to be available.

One of the primary methods of providing protection to an area is by containing riverine floodwaters via levees. The use of levees to protect flood plain lands is an ancient technique. A levee is simply a continuous ridge of earth constructed above existing flood plain topography. In earlier times, existing development was rather easily relocated to conform to a new ridge providing levee protection. However, in today's world, development is not so easily relocated. Ramping streets, highways, and railroads over a levee must take into account prevailing speed limits, sight distances, maximum allowable gradient changes, bridge approaches, and many other factors and the construction costs thereof. In many projects, the decision must be made to make the levee discontinuous due to breaks to allow for existing development that is either infeasible or too costly to relocate. These breaks make for closure structures that must be closed in times of flooding in order for the levee to be made continuous and thus serve its purpose. The ability to make timely closures is critical for a functional and safe levee flood protection project. The decisions regarding closure locations and abilities start in the project's plan formulation and continue through its design and operation. The West Des Moines - Des Moines, Iowa, local flood protection project includes levee gate closure structures on two streams, one with ample advance warning time and one with limited advance warning time. The plan formulation and design of the overall project included the overriding operational parameter of the advance warning time available at each potential gate closure location. This approach has resulted in a functional flood protection project that the cities of West Des Moines and Des Moines can easily and safely operate.

A market search located no systems that would provide the combination of flood warning time, reliability, simplicity and economics that we needed. We then developed a flood warning system to satisfy the project requirements. The major drawback of the state-of-the-art systems for our application is that they are too difficult for small rural communities to operate and maintain. Yet, many of those towns have a real need for automated flood detection. Additionally, much of the sophistication and speed provided by systems such as ALERT is not required in cases where the basin time of concentration is fairly long. Due to the relatively flat topography of the Great Plains, adequate flood warning can often be provided using stream stage detection alone, without real time rainfall information.

In addition, such projects generally require the local sponsor of the flood protection project to coordinate and implement timely operation of all closure structures to ensure the overall flood protection project functions as intended. The purpose of this paper is to discuss the functional performance and safety related aspects of a levee/floodwall and ringwall system for the city of Buena Vista, Virginia. A feasibility level report completed in 1S90 recommended construction of a levee/floodwall and ringwall system for the city of Buena Vista. This plan would provide a level of protection slightly greater than the 1% flood event and was determined to be the National Economic Development Plan (NED).

The findings of thisreport were that a significant flood threat existed and that further study was warranted. In the spring of 1989 the feasibility study for Roswell was initiated. The purpose of the study was to develophydrologic and hydraulic information, determine the magnitude and source of the flooding problems, and develop viable solutions to the problems, potentially in the form of a flood control project for Roswell. Roswell, New Mexico is subjected to the flows from two rivers which feed the Pecos River, a watershed comprising about 44,000 square miles. In order to define the source of the flooding problems, the hydrology and hydraulics of the individual rivers, as well as their interaction, needed to be understood. A major issue that arose was how to model the gravel pits located in the project area.

Because we are located in a part of the country which has frequent and severe thunderstorms, several federal and state agencies in this area have been very active in trying to improve the radar information for a number of different uses. Because of the amount of activity in this area and our involvement with the various agencies, the Southwestern Division (SWD) and the Tulsa District have been assigned as the lead division and district in development of the Corps use of the Next Generation Radar System (NEXRAD). The Hydrologic Engineering Center (HEC) and the Waterways Experiment Station have also been very active in developing methods and techniques for using radar information. This paper will focus on Corps access to the system and radar applications to reservoir control and hydrologic engineering. Charlie Sullivan, SWD, is the Corps point of contract for the NEXRAD project. Working for Charlie is Steve Fortenberry, a meteorologist with the National Weather Service (NWS), presently assigned to SWD. All coordination with other agencies involved in the NEXRAD project should go through SWD at this point in time. Within the Tulsa District, Clinton Word is the point of contact. Steve has made several technical presentations on NEXRAD and most districts or divisions already have someone familiar with the NEXRAD project. The NEXRAD project may very well prove to be one of the most significant improvements in data acquisition for real-time reservoir control in recent history.

Fundamental questions associated with the development of a flood-threat recognition system are: What warning times can be achieved, and how reliable will the warnings be? Answers to these questions depend on watershed and storm characteristics, and the flood-threat recognition method being considered. The tradeoff between warning time and warning reliability is illustrated, and methods for estimating warning time are discussed. JF - Technical Papers.

The two major issues/questions relating to overflow are: whether a load gain can be realized (and an economic load subsequently determined) if overflow is used under a given set of operational conditions; and, the characteristics of the overflow and the potential environmental effects due to turbidity or presence of contaminants. The decision to allow, restrict, or prohibit overflow in a given case should be based on an evaluation of these questions. Unfortunately, arriving at a decision requires an evaluation of the trade-offs between potential economic benefits and potential environmental effects. The degree to which a load gain can be achieved by overflow of a hopper or scow is dependent on the characteristics of the material being dredged, the method of dredging (hydraulic or mechanical), and the design of the equipment used. Although a number of theoretical studies, model studies, and field tests have been conducted, no routinely applied method is available to predict the potential load gain achieved by overflow under a given set of conditions. The concentrations of suspended solids in the overflow depends on the same parameters as the potential load gain. The higher the relative gain in load, the lower the solids concentration in the overflow. The subsequent extent of water column turbidity and bottom deposition due to overflow is dependent on site-specific hydrodynamic conditions. Technical information is related to the economic loading of hopper dredges and scows and the characteristics of overflow are limited. Additional guidance is needed when overflow can potentially achieve load gains. Equipment and techniques are needed to improve the efficiency of retention of material in hoppers and scows, and to predict the potential load gain in hoppers and scows under various conditions.

Using a tiered testing approach, the DMF first guides the user to a decision as to whether there is a 'reason to believe' sediment contamination may require disposal restrictions. The tiered approach allows the necessary and sufficient level of testing to be used for each specific project. The DMF computer software allows the user to easily navigate through the flow charts and will display prompts identifying required data inputs before proceeding to the next step. The first time this software is used on a test sediment, the user is required to provide bulk chemical analysis of the test sediments and of a reference sediment. Once these data are entered into the program, they are automatically saved on disk as discrete databases and may be recalled for future use. Depending upon which module is chosen, other specific data, such as bioassay or bioaccumulation test results, may be required. Once they have been entered, data may be shared among all modules without the need for reentering. This feature will also allow the user to investigate multiple disposal alternatives with minimal effort.

Around river locks and dams, bypassing techniques can be used to prevent shoaling which inhibits operation of lock gates. Sand bypassing is normally accomplished with dredges and to a lesser degree with fixed plants. Present fixed plants use pure suction or eductors (jet pumps) to remove the sand from the sea floor. Recent advancements in submersible centrifugal pumps (submersible pumps) have expanded their operating range, making them candidates for sand bypassing. Submersible pumps used for dredging applications are typically single-stage, vertical centrifugal pumps, with discharge pipe diameters of 4-12 inches. Pump sizes are usually based on discharge line diameters. They differ from conventional dredges in that the submersible pump itself is placed directly in the material to be dredged. According to the manufacturer, the Eddy Pump works on a different principle than the other submersible pumps. The impeller creates a swirling column of fluid that is directed down the inlet of the pump. The energy from this column agitates and separates the bottom materials to make them more easily suspended. The agitated solids and liquid flow upward in a counter flowing stream on the outside of the intake pipe. For most sands and silty materials, this swirling stream can potentially eliminate the necessity of using cutterheads and jetting rings. Depending on the size of the submersible pump, advertised production rates range from 50-300 cu yd/hr of sand (in-place volume). Submersible pumps have a number of potential advantages over conventional dredges in certain situations, primarily when production rates of under 300 cu yd are required. Typically, submersible pumps are less costly than a dredge; have lower mobilization/demobilization costs; and, depending on the deployment method, are more easily maneuvered into areas with limited access. One disadvantage of submersible pumps is that they tend to dig a vertical sided hole in cohesive material. This can make them susceptible to collapse of the hole.

AN - 36407305; 2827 AB - PURPOSE: Permanent designation of the interim Freshwater Bayou, Louisiana Ocean Dredged Material Disposal Site is proposed. In 1977, the site was approved for interim use for material dredged from the Freshwater Bayou federal navigation channel, based on historical use since 1968. The interim status was extended indefinitely in January 1980. The 1,242-acre site is located at the gulfward end of Freshwater Bayou. The site extends 4.1 miles with a width of 0.5 mile and parallels the west side of the Freshwater Bayou channel. Approximately 1.2 million cubic yards of dredged material are disposed in the site during each disposal operation, which occurs at two- to three-year intervals. Boundary coordinates of the preferred site are 29 degrees, 31 minutes, 59 seconds north latitude (N), 92 degrees, 18 minutes, 47 seconds west longitude (W); 29 degrees, 32 minutes, 4 seconds N, 92 degrees, 19 minutes, 17 seconds W; 29 degrees, 28 minutes, 24 seconds N, 92 degrees, 19 minutes, 28 seconds 28 seconds W; 29 degrees, minutes, 29 seconds N, 92 degrees, 19 minutes, 57 seconds W. POSITIVE IMPACTS: Designation of the site as a permanent area for disposal of dredged materials would provide an environmentally acceptable site for future disposal of material dredged to maintain the navigation channel in Freshwater Bayou. The bayou provides a link to the Gulf Intracoastal Waterway and Intracoastal City. The channel provides access for commercial traffic carrying crude petroleum, fish, manufactured products, water, and clay. The local and regional economies dependent in part on waterway transport along the associated waterways would be sustained. NEGATIVE IMPACTS: Use of the site would result in occasional, temporary increases in concentrations of suspended sediments and other pollutants, including mercury and manganese, short-term changes in grain size of surficial sediments at the site, localized burial of benthic organisms, and potential temporary mounding of substrate.

Preparation date: July 31, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MANATEE COUNTY, FLORIDA SHORE EROSION CONTROL PROJECT (DRAFT SUPPLEMENT 2 TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1973). AN - 36405194; 2824 AB - PURPOSE: Implementation of a shoreline protection project along the coast of Manatee County, Florida is proposed. This second draft supplement to the final environmental impact statement of August 1973 assesses the environmental impacts associated with adding 0.3 mile to the authorized county shoreline protection project. The only other addition to the plan would involve constructing two groins in the southern end of the project fill instead of one groin at the northern end. The currently preferred project measures would provide for restoration of 4.2 miles of shoreline on Anna Maria Key and construction of two rubble mound groins at the southern end of the project fill to reduce nourishment losses. Offshore borrow areas from which nourishment material would be dredged include: (1) an area approximately 1,000 feet wide by 20,000 feet long directly opposite the project beach and 1,000 to 1,500 feet offshore; (2) a rectangular area approximately 3,000 feet by 2,000 feet some 1,000 feet offshore of Longboat Pall; (3) a circular area with a 2,250-foot radius located approximately 5,000 feet off the northern tip of Anna Maria Key; and (4) a rectangular area approximately 1,000 feet by 3,000 feet located approximately 2,000 feet off the northern tip of Anna Maria Key. Area (1) would be used as the primary borrow site. The plan would also provide for periodic nourishment and mitigation of the loss of nearshore hard bottom habitat. The mitigation plan would involve cooperation with the county's artificial reef development program, including construction of 25 piles, 2,500 square feet in area, consisting of concrete pipes 4 to 10 feet long with 12-inch diameters and rocks piled 4 to 10 feet high and clustered in the county's permitted offshore site one mile from shore. Special measures would be taken to ensure that turtle nesting, bait fishery activities, historic and archaeological sites, and offshore reefs were not affected. The first cost of the recommended plan is $14.1 million; the annual cost of the project is estimated at $1.68 million. POSITIVE IMPACTS: Project measures would provide storm protection to upland structures and oceanfront property. More than 1.35 million square feet of recreational beaches would be created by nourishment. Annual benefits related to storm damage reduction, land loss prevention, and incidential recreational benefits would be worth $3.9 million, $92,000, and $300,000, respectively. A total of 70 acres of nesting habitat for endangered turtles would be provided. NEGATIVE IMPACTS: Benthic organisms inhabiting the beach zone would be smothered, although the area would be recolonized within one year. Some losses would be expected among organisms inhabiting the primary borrow area. The cost impact on the bait fishing industry of dredging the northern portion of the primary borrow area is estimated at $42,800 annually if the northern portion of the borrow area is dredged; if that portion were avoided, the cost to the industry would be reduced to $31,800. Beach nourishment and renourishment activities would result in temporary turbidity in the nearshore area; renourishment would occur over three-month periods at nine-year intervals.

Preparation date: July 30, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NORTH CHARLOTTE OUTER LOOP, FROM NC 27 (MOUNT HOLLY ROAD) TO I-85 NEAR THE U.S. 29 CONNECTOR, MECKLENBURG COUNTY, NORTH CAROLINA (FEDERAL AID PROJECT NO. F-117-1(6); STATE PROJECT NO. 8.1672202). AN - 36410284; 2725 AB - PURPOSE: Construction of the North Charlotte Outer Loop in Mecklenburg County and a small portion in the city of Charlotte, North Carolina is proposed. The 16- to 18-mile corridor extends between NC 27 (Mount Holly Road) and Interstate 85 (I-85) near the U.S. 29 Connector. The project would provide a multilane freeway with four lanes through the length of the study area; frontage roads would be provided between I-77 and NC 115. Three alternatives are under consideration, namely, a northern, middle, and southern alignment. Regardless of the alternative chosen, the freeway would have nine interchanges. The estimated costs of the Southern, Middle, and Northern alternatives are $175.0 million, $172.0 million, and $190.0 million, respectively. POSITIVE IMPACTS: Freeway availability would meet countywide goals to redirect residential growth to northern Mecklenburg County and provide better circumferential traffic movement between the developing employment bases in the northeast with residential development in the northwest. Air quality within Mecklenburg County, which is currently classified as a nonattainment area for carbon monoxide and hydrocarbons, would improve substantially. NEGATIVE IMPACTS: Rights-of-way acquisition and development would result in the displacement of 55 to 150 residences and 5 to 7 businesses, 16.1 to 36.6 acres of wetlands, 86.1 to 140.0 acres of prime farmlands, and 537.5 to 651.6 acres of natural wildlife habitat. The Middle Alignment would impact 10 graves located in a vacant lot just west of Rozelle Ferry Road. One to three greenways could be crossed, and 9 to 15 major creeks would be traversed. A total of 61 to 69 hydrologic crossings would be involved. The project would encounter one to seven sites that potentially contain hazardous materials. Noise standards would be violated in the vicinity of 241 to 267 residential receptors. One or two historic properties and up to three archaeological sites, eligible for inclusion on the National Register of Historic Places, would be affected.

Preparation date: July 26, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WEST CHARLOTTE OUTER LOOP, FROM I-77 SOUTH NEAR WESTINGHOUSE BOULEVARD TO NC 27, MECKLENBURG COUNTY, NORTH CAROLINA (FEDERAL AID PROJECT NO. F-117-1(5); STATE PROJECT NO 8.1672201). AN - 36400904; 2726 AB - PURPOSE: Construction of the West Charlotte Outer Loop in Mecklenburg County and a small portion in the city of Charlotte, North Carolina is proposed. The approximately l3-mile corridor extends between NC 27 (Mount Holly Road) on the north and Interstate 77 (I-77) on the south. The project is located in a largely rural portion of Mecklenburg County between the Catawba River and Charlotte/Douglas International Airport. The southern project terminus would be at the interchange planned for the south Outer Loop, between the existing Arrowood Road and Westinghouse Boulevard interchanges. The northern terminus would be on NC 27 at a location to be determined, but generally between the Catawba River and Little Rock Road. The project would provide a four-lane freeway through the length of the study area. Three build alternatives are under consideration, namely, the East, Middle, and West corridors. Three crossover options are included, which would allow the possibility of transitions between the three build alternatives; the crossover options would extend 3.2 to 3.5 miles. The East Corridor would generally follow the conceptual location shown in the Charlotte-Mecklenburg County Thoroughfare Plan, except for a more eastern alignment south of Byrum Drive. The Middle Corridor would also generally follow the thoroughfare location, except for a shift to the west south of Byrum Drive. The West Corridor would be the least compatible with the thoroughfare plan location, crossing portions of Lake Wylie and lying on the western edges of the study area. Depending on the alternative chosen, the freeway would have seven or eight interchanges. The estimated costs of the East, Middle, and West corridor alternatives are $174.9 million, $181.3 million, and $183.8 million, respectively. Cost estimates for the three crossover options are $29.2 million, $31.3 million, and $28.9 million. POSITIVE IMPACTS: Freeway availability would increase safety within the area by redirecting traffic from more congested and hazardous existing highways to the loop. Traffic levels within the city of Charlotte would be reduced, and travel time, fuel consumption, and vehicle operating costs would decline. NEGATIVE IMPACTS: Rights-of-way acquisition and development would result in the displacement of 62 to 115 residences and 3 to 9 businesses, 5 to 17 acres of wetlands, 18 to 32 acres of floodplains, 42 to 109 acres of prime farmlands, 457 to 534 acres of woodland habitat, and 98 to 115 acres of developed land; in all, 656 to 747 acres of land and open water would be converted to highway rights-of-way. The West Corridor would conflict with existing land use plans, sever access to Lake Wylie, and generally disrupt local land uses. Numerous streams would be traversed. Noise levels would increase substantially and, in some cases, standards would be violated in the vicinity of 9 to 23 receptors. One historic property, eligible for inclusion on the National Register of Historic Places, would be affected.

Preparation date: July 26, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CONSTRUCTION OF ROUTE 198 FREEWAY IMPROVEMENTS BETWEEN PLAZA ROAD AND MOONEY BOULEVARD IN THE CITY OF VISALIA, TULARE COUNTY, CALIFORNIA. AN - 36400564; 2721 AB - PURPOSE: Implementation of the State Route 198 Freeway Conversion Project in Tulare County, California is proposed. The project corridor would generally run between Route 99 and Route 63 in the city of Visalia. Several Build alternatives and a No Build Alternative are under consideration. These alternatives vary in terms of freeway profile, interchange design, frontage road and ramp configurations, amount of rights-of-way required, and widening the existing highway to the north or the south. Regardless of the alternative chosen, the project would convert the existing four-lane expressway to an initial four-lane, ultimate six-lane freeway. During preliminary project evaluations, the project corridor was divided into West and East segments to make a distinction between rural and urban land use differences along the route. The western end of Route 198 from Plaza Drive to Akers Road is a rural area, while the eastern end, from Akers Road to Mooney Boulevard, is urban in character. Freeway conversion of the West Segment would use the existing lanes and the existing 22-foot-wide median. Future construction of the ultimate six-lane freeway facility with a 30-foot median would require 23 to 35 additional feet of rights-of-way on each side of the roadway. An interchange would be constructed at Shirk Road. Access to Route 198 at Road 86, Road 88, and Roeben Road, and all private access would be discontinued. Frontage roads would be provided. The East Segment would align totally to the south of the existing roadway from Akers Road to Woodland Drive and would follow one of three alternatives, one south of the existing roadway, one north of the roadway, and one consisting of a combination of the two with a half-depressed profile. Frontage roads and interchanges would control and provide access. POSITIVE IMPACTS: In general, the project would reduce traffic congestion and automobile accidents and provide traffic capacity for planned growth in Visalia. The project would forward the land use plans of Tulare County, Visalia, the Tulare County Association of Governments, and the California Urban Development Strategy. Transportation energy efficiency would be increased by 13 to 14 percent; the construction energy payback period would be five to eight years. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 24 to 37 landmark oak trees; a total of 473 to 641 trees would require removal. Most of the vegetation in the Route 198 right-of-way would be removed. Removal of up to 1.3 acres from along Mill Creek and the vicinity of West Main Street Park would contribute to the cumulative loss of natural habitat in the project area. Construction activities could cause sedimentation and erosion of Mill Creek and Persian Ditch, and new cut slopes and embankments could lead to erosion and degradation of these two surface channels. Up to 70 acres of agricultural land would be lost, and 23 to 63 housing units would be displaced. Noise levels generated by traffic along the corridor would exceed state and federal standards, with increases as great as 18 decibels on the A-weighted scale in some areas. Carbon monoxide levels along the corridor would exceed the 8-hour standard. The project would encroach on a Special Flood Hazard Area. Parkland and recreational land would be replaced.

Preparation date: July 25, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PASCAGOULA HARBOR OCEAN DREDGED MATERIAL DISPOSAL SITE DESIGNATION, MISSISSIPPI. AN - 15224658; 2747 AB - PURPOSE: Designation and use of a new ocean dredged material disposal site in the Gulf of Mexico, south of Pascagoula, Mississippi, is proposed to receive material dredged from the Mississippi Sound area that meets the ocean dumping criteria. The proposed site would encompass part or all of the former interim disposal site and an adjacent charted former disposal site. For the purpose of this analysis, the proposed site is considered a new site and an enlargement of the former interim site. The interim site was designated on an interim basis on January 11, 1977; this interim designation was extended until December 31, 1988. The newly designated site would have the following boundary coordinates: 30 degrees, 12 minutes, 6 seconds north latitude (N); 88 degrees, 44 minutes, 30 seconds west longitude (W); 30 degrees, 11 minutes, 42 seconds N; 88 degrees, 33 minutes, 24 seconds W; 30 degrees, 8 minutes, 30 seconds N; 88 degrees, 37 minutes, 00 seconds W; 30 degrees, 8 minutes, 18 seconds N; 88 degrees, 41 minutes, 54 seconds W. Center coordinates for the site would be 30 degrees, 10 minutes, 9 seconds N; 88 degrees, 34 minutes, 12 seconds W. The site is within an economically transportable distance, yet is sufficiently removed from amenities such as beaches, fish havens, artificial reefs, and hard bottom areas, so these will not be affected. POSITIVE IMPACTS: The availability of the dredged material disposal site would allow for the disposal of 1.0 million cubic yards of new material and 225,000 cubic yards of maintenance material dredged every 18 months from the federal channels in the Upper Pascagoula River, ensuring the economical viability of the associated port and transportation facilities. Use of the gulf disposal site would also allow the Department of the Navy to establish a naval station at Pascagoula as part of the Gulf Coast Strategic Homeporting project. The station would be developed on Singing River Island, which currently serves as the site for disposal of material from the federal navigation project. The site would also provide for a means of disposing material dredged to maintain waterways associated with the Naval station, as well as of disposing material dredged by local entities and private citizens. NEGATIVE IMPACTS: The proposed action would adversely impact water quality and alter site bathymetry and sediment composition. Disposal activities would result in temporary turbidity and smother benthos and some demersal fish. Monitoring and management programs would be established to prevent any long-range environmental impacts.

AN - 36393060; 2741 AB - PURPOSE: Alternatives to the operation and regulation of Lake Red Rock in Marion County, Iowa are being considered. The current operation plan requires that the lake be raised at intervals to compensate for sedimentation and to maintain the 50,000 acre-feet of water originally approved for the reservoir. This second final supplement to the final environmental impact statement (EIS) of August 1976 addresses the impacts of raising the permanent conservation pool at Lake Red Rock from elevation 734 National Geodetic Vertical Datum (NGVD) to 742 feet NGVD. Elevation 742 NGVD represents the conservation pool necessary to store 100 years of sediment accumulation, as well as the volume of water required to provide reliable low-flow augmentation to downstream river reaches during severe drought conditions. The conservation pool was raised from elevation 728 NGVD to elevation 734 NGVD in November 1988 as a result of recommendations in the Lake Red Rock Water Control Plan issued in May 1988. Since that time, the state of Iowa has requested that the conservation pool at the lake be raised to the 100-year design level of 742 NGVD. This supplemental EIS also describes the environmental, cultural, economic, and social impacts of a 742-foot pool raise and includes a Water Control Plan that addresses the water control aspects of a conservation pool raise to elevation 742 feet NGVD and a Supplemental Master Plan that describes the details of impacts to federal facilities and planned facility relocations. Based on the information presented in this study, the Rock Island District recommends a permanent conservation pool elevation of 742 feet NGVD, with a yearly fall raise to elevation 744 NGVD for the benefit of migrating waterfowl. POSITIVE IMPACTS: The recreation experience at the lake would be enhanced by improving aesthetics, boating, fishing, and wildlife habitat, and part of the recreational needs of south-central Iowa would be fulfilled. Residential property values could increase slightly. The increased potential for recreation visitors to the lake could attract new businesses to the area and create new employment opportunities. Through the operation and maintenance of Lake Red Rock, urban and rural areas would be protected from floods. NEGATIVE IMPACTS: Construction machinery would generate a temporary increase in noise during scheduled relocation of facilities, creating a minor, short-term disturbance to recreationists at the lake. Recreation at various facilities would be temporarily disrupted during the construction phase. The values of farm properties could be adversely impacted. An increased risk of flooding, resulting from any raise in pool elevation, is perceived by area farmers. There would be periodic inundation of terrestrial habitat between 725 and 780 feet NGVD, fluctuations in lake levels would result in an unstable environment for aquatic life, and periodic inundation of historical and archaeological sites probably would continue.

AN - 36407003; 2685 AB - PURPOSE: Three proposed hydroelectric projects that would produce an annual total of approximately 450 gigawatt-hours (GWh) of electric power and would be sited on the mainstem of the Snake River in the upper Snake River Basin near Twin Falls, Idaho have been evaluated for their environmental effects and economic benefits. Applications for licenses to construct, operate, and maintain the three proposed projects were filed by Idaho Power Company (FERC No. 18) for a new license with expanded capacity, Cogeneration, Inc. (FERC 4797), and B&C Energy, Inc. (FERC No. 5797). Additionally, potential modifications to the licensed Milner Project (FERC No. 2899), arising from studies required in the license, were evaluated so as to fully utilize the water power resource. These modifications would produce an additional 33 GWh annually. The projects would be located along a 32-mile stretch of the river in the Upper Snake River Basin, a large, sparsely populated, diverse area that includes most of south-central Idaho. Each license would allow a nonutility licensee to construct its proposed project after securing a contract for the sale of power from, and securing financing for, its proposed project. Projects to be licensed would include (1) the Star Falls Project, to be located 8 miles downstream of Milner Dam; (2) the existing Twin Falls Project, to be located 3 miles upstream of Twin Falls; and (3) the Auger Falls Project, to be located 3 miles northwest of Twin Falls. The Milner, Star Falls, and Twin Falls projects would include dams and reservoirs, while major structures at the Auger Falls project would consist of a concrete diversion dam, overflow weir, and power canal. All projects would feature run-of-river designs, and transmission facilities would be constructed in association with the generation facilities. The potential modifications to the Milner Project would involve the addition of a bypass powerhouse at the dam. The Milner Project would have two generating units, a hydraulic maximum capacity of 4,000 cubic feet per second (cfs), a minimum capacity of 900 cfs, and an annual generation output of 177.0 GWh. The Star Falls Project would have one generating unit, a maximum hydraulic capacity of 5,500 cfs, a minimum capacity of 1,000 cfs, and an annual generation output of 112 GWh. The Twin Falls Project would have one generating unit, a maximum capacity of 4,960 cfs, a minimum capacity of 380 cfs, and an annual generation output of 189.0 GWh. The Auger Falls Project would have three generating units, a maximum capacity of 5,000 cfs, a minimum capacity of 200 cfs, and an annual generation output of 149.0 GWh. A fish ladder would be constructed in association with the Auger Falls Project. Other mitigation measures implemented in association with the projects would include the formation of river islands, erosion sedimentation controls, construction of surface drainage swales, development of wildlife ponds, creation of other wetland areas, construction of osprey nesting platforms and goose nesting structures, extension of cattle-guard fencing, use of transmission structure designs that would prevent electrocution of large raptors, and development of artificial burrows for owls. Provisions for recreational access to the river would be made at several locations. Project construction schedules range from 19 months to 3 years. The preferred action is the licensing of the Twin Falls and Auger Falls projects, with staff-recommended mitigation, denial of a license for the proposed Star Falls Project, and amending the Milner Project license to include a bypass powerhouse at the base of the dam and an expanded capacity at the main powerhouse. POSITIVE IMPACTS: Operation of the projects would improve the reliability of the power supply infrastructure in the region and provide a portion of the additional electrical energy requirements estimated for 1992 and beyond. Local and regional economies would be boosted, and fulfillment of federal power requirements would be supported. NEGATIVE IMPACTS: Implementation of the projects would have significant impacts on resident trout populations, wintering waterfowl, raptors, riparian-associated wildlife and vegetation, water quality, visual quality, and recreational and cultural resources.

AN - 36384285; 2750 AB - PURPOSE: Construction of a confined disposal facility (CDF) for polluted sediments dredged from the Maumee River federal navigation channel at Toledo Harbor, Ohio is proposed. Toledo Harbor is located on the northwest shore of Lake Erie, approximately 100 miles west of Cleveland, Ohio and 60 miles south of Detroit, Michigan. The harbor is dredged annually, using normal operation and maintenance authorities of the Corps of Engineers. Dredging results in the need for annual disposal of 400,000 to 700,000 cubic yards of heavily polluted materials. Objectives of the plan include maintaining adequate water depths for commercial and recreational navigation; providing safe handling and transportation of heavily polluted sediments to a permanent, confined disposal site (or sites); minimizing adverse impacts to aesthetics and fish and wildlife values; protecting water quality; and preserving significant cultural resources. The preferred alternative would involve construction of a new dike wall approximately 4,260 feet long and 29.5 feet high to enclose a 155-acre shallow water area adjacent to the federal channel and the existing CDF; it would have a capacity of 8.764 million cubic yards of consolidated dredged material, giving the new CDF a maximum effective life of 21.9 years. A set of three water quality monitoring wells would be installed in the dike. Four 8-foot by 10-foot rectangular overflow weirs of fabricated steel panels with adjustable wood stop logs, outfall pipes, and access walkways would be constructed. To mitigate for bird kills associated with potential botulism outbreaks, a botulism control plan would be implemented. Quick removal of sick and dead birds from the affected area would also be implemented as a mitigation measure. First cost of the project is estimated at $11.67 million, and the benefit-cost ratio is estimated at 2.05. POSITIVE IMPACTS: The full commercial and recreational navigation potential of Toledo Harbor would be assured for 21 years. Businesses and industries that rely on Toledo Harbor navigation would continue and/or expand, and the project would facilitate area growth. Minor increases in employment would be seen during CDF construction, and harbor-related employment would be maintained. The proposed plan would allow for continual dredging of polluted sediments and confined disposal for the next 21 years. Construction of the dike would tend to deflect more polluted Toledo River water further into the Maumee Bay, increasing dilutional effects. NEGATIVE IMPACTS: The proposed alternative would result in the loss of 169 acres of shallow water habitat, including mud bottom habitat and shady shoal habitat as well as some riprap shoreline (1.5 acres) and aquatic emergent vegetation.

Preparation date: July 11, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CORE CREEK BRIDGE REPLACEMENT, ATLANTIC INTRACOASTAL WATERWAY BRIDGE, CARTERET COUNTY, NORTH CAROLINA. AN - 36392100; 2727 AB - PURPOSE: Replacement of the Core Creek Atlantic Intracoastal Waterway (AIWW) bridge in Carteret County, North Carolina is proposed. The bridge crosses the AIWW at mile 195.8 and is located in the coastal plain of Carteret County. It is part of North Carolina Highway (NC) 101, which runs from Beaufort to Havelock, North Carolina. The proposed replacement bridge would be a 2,950-foot two-lane, high-level, fixed-span structure with a 65-foot vertical clearance and a minimum 120-foot horizontal navigational clearance over the AIWW. The crossing, which would lie approximately 900 feet south of the existing bridge, would reconnect with NC 101 approximately 3,000 feet east of the waterway. Borrow sites for necessary fill would be located on either side of the AIWW; each of the two sites would cover approximately 25 acres. The approach for the bridge would leave NC 101 at a point approximately 4,100 feet west of the AIWW. The alignment would reconnect with NC 101 on the other side of the bridge, approximately 3,000 feet east of the waterway. The total length of the project is 7,400 feet, with 2,650 feet of approach on the west side, 1,800 feet of approach on the east side, and 2,950 feet of bridge. Bridge approaches on each side of the waterway would require placement of approximately 300,000 cubic yards of fill. Fill height at the bridge abutments would be approximately 30 feet on the west side and 40 feet on the east side of the AIWW, with widths of 220 feet and 280 feet, respectively. Fill width would taper as the alignment approaches NC 101. Rights-of-way widths vary from 360 feet at the highest point of the approach fills to 140 feet at the connections with NC 101. Additional rights-of-way would be required for two-lane connector roads at each end of the alignment. POSITIVE IMPACTS: Unsafe operating conditions characterizing the bridge, associated with structural deterioration, blind curves, and inadequate roadway width, would be remedied. The connector roads would facilitate access to the new road and access within the community. NEGATIVE IMPACTS: Rights-of-way development would result in relocation of 5 permanent residences and 3 secondary residences (mobile homes) and displacement of 13 acres of pine forest, 11 acres of mixed pine /hardwood, and 118 acres of pine plantation. Approximately 9.5 acres of palustrine forested wetlands would be filled; wetland losses would include 6.0 acres of deciduous pine wetlands and 3.5 acres of pine-dominated wetlands. Approximately 4,480 square feet of pine-dominated wetlands would be affected by the construction of piers and footings. Approximately 1,800 square feet of estuarine bottom would be filled by pier footings. Removal of the existing bridge would result in the loss of a structure that is eligible for the National Register of Historic Places. The new bridge would constitute a visual obstruction, affecting area aesthetics.

AN - 36392384; 2752 AB - PURPOSE: Designation of an ocean dumping site for 170,000 cubic yards of material dredged annually to maintain the Port Mansfield Entrance Channel on the Gulf Coast of Texas is proposed. The interim site was determined to be environmentally unacceptable due to its location in a jetty buffer zone that is excluded from ocean dumping. The preferred site lies 5,200 feet in a direction parallel to the channel (east/west) and 3,000 feet in a direction perpendicular to the channel (north/south). Specific site coordinates are 26 degrees, 34 minutes, 24 seconds north latitude (N); 97 degrees, 15 minutes, 15 seconds west longitude (W); 26 degrees, 34 minutes, 26 seconds N; 97 degrees, 14 minutes, 17 seconds W; 26 degrees, 33 minutes, 57 seconds N; 97 degrees, 14 minutes, 17 seconds W; 26 degrees, 33 minutes, 55 seconds N; 97 degrees, 15 minutes, 15 seconds W. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means for disposal of material dredged from the entrance channel, ensuring the continued usefulness of the Port of Mansfield for navigational purposes. The port would continue to serve the economy of the Texas Gulf Coast. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, as well as temporary burial and mortality of benthic organisms and temporary mounding of substrate.

Preparation date: July 3, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DELAWARE RIVER COMPREHENSIVE NAVIGATION MAIN CHANNEL DEEPENING, PHILADELPHIA, PENNSYLVANIA TO DELAWARE BAY. AN - 36391938; 2751 AB - PURPOSE: Implementation of navigation improvements along the Delaware River from the Beckett Street Terminal in Camden, New Jersey through Philadelphia Harbor, Pennsylvania to deep water in the Delaware Bay off Delaware, a distance of approximately 102.5 miles, is proposed. Channel widths currently range from 400 feet in Philadelphia Harbor to 1,000 feet in the bay. Throughout Philadelphia Harbor, the channel is 40 feet deep on the west side and 37 feet deep on the east side. Widening has been provided for at critical bends. There are 19 anchorages on the Delaware River; all but 6 are natural deep-water anchorages. The project includes 12 training dikes to reduce shoaling in the channel and anchorages or to minimize dredging and disposal costs. The currently recommended plan would provide for a two-way, full width channel of variable widths, with a depth of 45 feet below mean low water (MLW) and an allowable dredging overdepth of 2 feet. The channel side slopes would be 3 horizontal to 1 vertical. Channel dimensions below the Walt Whitman Bridge are based on a 160,000-dead-weight-ton (DWT) tanker with a length of 931 feet, a beam of 145 feet, and an operating draft of 45 feet. The design vessel for Philadelphia Harbor and the Beckett Street Terminal access would be a 100,000-DWT dry bulk vessel with a length of 830 feet and beam of 128 feet. The selected channel dimensions would allow for navigation practices similar to existing conditions that allow full use of the tide range by inbound vessels. The channel width would range from 400 feet in Philadelphia Harbor to 800 feet from the Philadelphia Navy Yard to Bombay Hook and then 1,000 feet in the Delaware Bay. The plan would include all appropriate bend widening, as well as provision of a two-space anchorage of compatible depth at Marcus Hook anchorage. The project would also include utility relocations, aids to navigation, and lands, easements, rights-of-way, and disposal areas as necessary for initial construction and maintenance of the project. Initially, the project would require dredging of 52.5 million cubic yards; annual maintenance dredging would amount to 756,000 cubic yards. The estimated costs of the initial dredging, disposal, utility relocations, navigational aids, and associated activities are $249.8 million, $26.2 million, $2.9 million, $800,000, and $19.4 million, respectively. The estimated benefit-cost ratio is 1.16. POSITIVE IMPACTS: Expansion of the navigational channels along the Delaware River would allow use by deep-draft vessels with full cargoes. Harbor safety and efficiency would be enhanced simultaneously with easing the movement of goods into and from markets along the Eastern Seaboard. Annual benefits redounding from the project would be worth $42.9 million. NEGATIVE IMPACTS: Benthic organisms would be destroyed in dredged areas and in areas affected by dredged material disposal. Removal of approximately 420,000 cubic yards of rock from the river channel would adversely affect the aquatic environment; use of explosives would be required for rock removal.

Preparation date: July 3, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GULFPORT HARBOR NAVIGATION IMPROVEMENTS, HARRISON COUNTY, MISSISSIPPI. AN - 36403702; 2746 AB - PURPOSE: Expanding the capacity of the Gulfport Harbor deep draft navigation project in Harrison County, Mississippi is proposed. The recommended plan would involve widening and deepening the existing Gulfport Harbor navigation channel from its current 30- by 220-foot dimensions in the turning basin, anchorage area, and Mississippi Sound and 32- by 300-foot dimensions in the Gulf of Mexico up to the authorized dimensions of 36 feet deep by 300 feet wide and 30 feet deep by 400 feet wide, respectively. More specifically, the project would involve deepening the entrance and southern portion of the anchorage basin to 36 feet; deepening the northern portion of the anchorage basin to 32 feet; deepening the Mississippi Sound channel to 36 feet at the existing width of 220 feet; deepening the Ship Island Pass and Gulf channels to 38 feet at the existing width of 300 feet; realigning the channel across the bar in Ship Island Pass approximately 1,900 feet to the west; and providing bend widening at various stations. Suitable material dredged from the Ship Island Pass channels would be dumped in the littoral zone southeast of Cat Island or in the beach nourishment area at Fort Massachusetts. New work material dredged from the Mississippi Sound and Gulf of Mexico channels would be dumped in the designated ocean disposal sites at Gulfport, except for 1.5 million cubic yards of virgin material dredged from the harbor entrance area (turning basin) that would be dumped in the proposed Port Gulfport expansion area, 1.0 million cubic yards of virgin material dredged from the Mississippi Sound channel that would be dumped in a thin layer during the demonstration program investigating the effects of such disposal on marine resources, and future maintenance material that would be disposed by using a combination of open water disposal sites in the Mississippi Sound, the littoral zone and/or beach nourishment sites, and the designated ocean disposal sites. POSITIVE IMPACTS: Increased capacity at Gulfport Harbor would decrease waterborne transportation costs and increase commerce in Harrison County, which is heavily dependent on the economic benefits offered by the harbor. Safety within the harbor would also be enhanced due to wider waterway turning capacity. NEGATIVE IMPACTS: Dredging and disposal of dredged material would result in temporary localized turbidity and alteration of bottom topography at the disposal site.

Early attempts at using direct pump-out (DPO) hopper dredges for beach nourishment centered on docking the dredge to a floating or jack-up barge moored offshore. Submerged pipeline extended from the barge to shore. High mooring forces and relative motion between dredge and barge make the arrangement impractical for most open coastal locations. For many years the oil industry has used monobuoys to load and unload tankers. While a buoy holds a tanker in position, a hose carries oil from the tanker through the buoy to a submerged pipeline on the sea floor which leads to shore. The dredging industry, particularly in Europe, has adapted this technology for use with direct pumpout hopper dredges. Although a moored buoy is the most common type of connection between submerged pipe and dredge, a variety of types can be used: floating swivel pontoon; submerged swivel pontoon; swivel tower on submerged pontoon Seabed piled; and swivel pile cap. Two US dredging companies have single point moorings which are regularly used with their dredges. One uses its buoy primarily with its hopper barge, but occasionally uses it with its hopper dredges. The other uses its similar buoy with its hopper dredge. Most other US dredging contractors have at least one dredge equipped for direct pumpout. Many of these dredges have completed shore placement projects by either connecting to pipes leading directly to shore or connecting to floating hose extending from a booster pump on a jack-up barge.

AN - 36404442; 2682 AB - PURPOSE: Closure of Fort Douglas in Davis, Salt Lake, Tooele, and Utah counties, Utah is proposed. Currently, the primary mission of Fort Douglas is to provide administrative, logistical, maintenance, and family support services to active and reserve tenant units and off-post reserve units in the states of Utah, Idaho, and Montana. The fort contains 115 buildings and two other structures (a bandstand and a swimming pool). Approximately 51 acres of the 119-acre fort would be excessed; the remaining 68 acres would be retained by the Army for use as a reserve center. Other functions currently located at the fort would be relocated to Fort Carson, Colorado; Tooele Army Depot, Utah; Fitzsimmons Medical Center, Utah; and leased space in Salt Lake City, Utah. In order to implement the closure and relocation, it would be necessary to improve utilities systems and parking at Fort Douglas and renovate structures to accommodate the Army Readiness Group at Fort Carson, the old hospital complex, and one building to accommodate the relocation of the 62nd Ordnance Detachment to Tooele Army Depot. The property at Fort Douglas scheduled for retention is currently used by reserve units principally for administrative, training, support, assembly, recruiting, and storage purposes. The 96th Army Reserve is the major reserve command on the post and would assume command of the reserve center, which would host 21 additional reserve and reserve support units. Approximately 49 acres within the fort, which constitute an historic site related to the protection of a 19th Century mail route from hostile Indians, would be planned for preservation. POSITIVE IMPACTS: Relocation of Army missions from Fort Douglas to other Army facilities in the region would increase the operational flexibility of these missions, which are currently affected by the small size of the fort and its historic status; the latter condition prevents significant renovation of structures. Historic structures within the fort property would be preserved for appreciation by present and future generations. The facility would continue to serve its functions as a reserve and recruiting headquarters. In general, the mission of the U.S. Army, currently served by the existing fort would be made more efficient and effective. NEGATIVE IMPACTS: A significant portion of the historic property associated with Fort Douglas would be excessed and, hence, lost to federal control, possibly jeopardizing its historic resources.

AN - 36400919; 2744 AB - PURPOSE: Continued use of the Massachusetts Bay Disposal Site, formerly the Foul Area Disposal Site, in Massachusetts for dredged material disposal is proposed. The site is located in Massachusetts Bay in approximately 90 meters of water and is two nautical miles in diameter. The center of the site is at 42 degrees, 25 minutes, 7 seconds west longitude and 70 degrees, 34 minutes north latitude, approximately 22 nautical miles east of Boston. The site is currently operating as an Environmental Protection Agency-approved interim dredged material disposal site. The U.S. Army Corps of Engineers (COE) has disposed or permitted disposal of 2.8 million cubic yards of dredged material at the site over the past 12 years. Final site designation would not constitute approval for actual disposal of dredged material; it would only serve to identify an ocean disposal alternative for individual dredging project reviews. All dredged material proposed for ocean disposal would continue to be evaluated on a project-by-project basis by the COE. In response to comments on the draft environmental impact statement, urging an expanded consideration of alternatives, this supplement was prepared to expand the Environmental Protection Agency's evaluation of such alternatives. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means for disposal of material dredged from the region, which includes areas extending from Gloucester to Plymouth, Massachusetts, for navigational purposes. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, as well as short-term changes in the grain size of surficial sediments, localized burial of benthic organisms, and temporary mounding of substrate.

AN - 36384530; 2723 AB - PURPOSE: Construction of a 16.9-mile multilane, divided highway, designated as Federal Aid Primary (FAP) 426, from the intersection of U.S. Route 20 (Lake Street) and Lovell Road east of Elgin, easterly to the intersection with the proposed West O'Hare expressway at the west side of Chicago-O'Hare International Airport near Thorndale Avenue and York Road, is proposed. The project would extend in an east-west direction through northern Du Page and Cook counties, Illinois. The proposed alternative would include intersections at Lovell Road, Bartlett Road/Oak Avenue, Park Boulevard, East Bartlett Road (North Avenue), Springinsguth Road/Illinois Route 19, Illinois Route 19, and Illinois Route 19/Rodenburg Road. Interchanges would be constructed at Church Road, U.S. Route 20, Gary Avenue, Rodenburg Road, Wright Boulevard, Roselle Road, Meacham Road/Medinah Road, Rohlwing Road, Interstate 290, Arlington Heights Road/Prospect Avenue, Wood Dale Road, and Illinois Route 83. The specific design of the interchange at Thorndale Avenue/York Road would be defined and evaluated in design and environmental studies for the West O'Hare Expressway. The highway design would include a 60-foot-wide median that could be used for high-occupancy vehicle and light rail transit development in the future. Traffic noise attenuation barriers would be included in the project design at Roselle, Elk Grove Village, and Hanover Park. The estimated cost of the project is $350 million in 1989 dollars. Due to funding limitations, a staged construction plan would be implemented. POSITIVE IMPACTS: The proposed highway improvement would provide needed traffic capacity in the corridor between Elgin and Chicago-O'Hare International Airport, relieving local arterial traffic congestion. Long-term employment would be generated by construction of FAP 426. Property values would rise due to increasing population and economic growth, and improved accessibility would stimulate more efficient use of existing business, commercial, industrial, and manufacturing land uses. Air pollution from automobile emissions would be reduced. NEGATIVE IMPACTS: The project would require approximately 37 residential, 8 commercial, and 1 industrial relocations. Six streams would be crossed by the proposed alignment, resulting in erosion of soil and subsoil into the streams. The loss of wetlands would amount to 42.4 acres. Numerous residential receptors would experience traffic noise equal to or greater than the federal noise abatement criteria for residences. Two houses of local historical significance, which could be eligible for the National Register of Historic Places due to significant archaeological and architectural features, would be displaced. Spillage of oils, grease, and fuel during construction could adversely affect surface water quality.

AN - 36406867; 2749 AB - PURPOSE: Widening and deepening portions of the Wilmington Harbor waterway system between the Fourth East Jetty Channel in the Cape Fear River to a point 750 feet above the Hilton Railroad Bridge on the Northeast Cape Fear River in New Hanover and Brunswick counties, North Carolina are proposed. This final supplement to the final environmental impact statement (FEIS) of December 1979 addresses changes in the project design since the issuance of the FEIS. These changes would involve deepening the channel to 38 feet (plus 1 foot allowable overdepth) rather than 35 feet (plus 2 feet of required overdepth), widening the harbor turning basin on the west rather than the east side, and extending the 38-foot channel an additional 3,350 feet further upstream. The full harbor plan as currently proposed would involve widening the Fourth East Jetty Channel by 100 feet at the existing depth of 38 feet for a distance of approximately 8,000 feet; deepening the navigation channel from 32 feet to 38 feet, plus 1 foot of allowable overdepth at a width of 400 feet between Castle Street (Cape Fear Memorial Bridge) and the NC 133 Highway Bridge; widening the turning basin just upstream of the mouth of the Northeast Cape Fear River by 50 feet on the west side at a depth of 38 feet, plus 1 foot of allowable overdepth; and deepening the navigation channel from 32 feet to 38 feet, plus 1 foot of allowable overdepth over a width of 300 feet from the NC 133 Highway Bridge to the Hilton Railroad Bridge, located 2,600 feet upstream, and deepening the navigation channel from 25 feet to 38 feet, plus 1 foot of allowable overdepth over a width of 200 feet from the Hilton Railroad Bridge to a point approximately 750 feet upstream. A total of 1.4 million cubic yards of material would be removed to create the desired waterway depths. Average annual maintenance dredging would result in the removal of 106,200 cubic yards of material. Material would be excavated via pipeline dredge. Dredged material would be dumped in upland diked disposal facilities. POSITIVE IMPACTS: Waterway improvements would result in transportation savings, expanded port activity, and increased economic diversity, employment, and property values. NEGATIVE IMPACTS: Some utility line relocations would be required. Blasting rock from the river bottom during excavation of the turning basin could place river bottom material into suspension. The new channel dimensions could have a slight impact on saltwater intrusion into the Cape Fear River system, resulting in some habitat losses. Benthic organisms would be destroyed during dredging. Approximately 0.85 acre of mixed brackish marsh fringe, located opposite the State Port, would be converted to open water as a result of the widening of the Fourth East Jetty Channel. Upland diked disposal facilities would damage wildlife habitat. Historic vessels could be encountered during project implementation.

Preparation date: June 27, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BATIQUITOS LAGOON ENHANCEMENT PROJECT, CARLSBAD, CALIFORNIA. AN - 36392327; 2736 AB - PURPOSE: Restoration and enhancement of Batiquitos Lagoon as a biological and physical system is proposed. The lagoon lies in the city of Carlsbad in northern San Diego County, California. More specifically, the lagoon is situated 90 miles south of Los Angeles and 35 miles north of San Diego. The enhancement project would involve dredging to produce shallow subtidal and intertidal habitats and maintaining an open ocean inlet with sufficient tidal prism to ensure flushing and good water quality throughout the lagoon. Key construction components of the project would include restoring tidal action to the lagoon by constructing a nonnavigable tidal inlet structure and dredging the lagoon to produce adequate subtital and intertidal zones that would create an adequate tidal prism for tidal flushing; nourishing ocean beaches at Batiquitos Beach and Encinas Creek Beach with dredged lagoon sands; replacing or rehabilitating the East and West Carlsbad Boulevard bridges; installing pedestrian/emergency access over the proposed tidal inlet to provide continued lateral beach access; and creating a freshwater marsh (pond) in the eastern portion of the East Basin. The West and Central basins would be excavated to 5.5 feet below mean lower low water (MLLW). The East Basin would be excavated to 2.5 feet below MLLW. Dredging within the East Basin would be deeper between the Interstate 5 (I-5) bridge and a point approximately 3,000 feet to the east. The elevation would vary from the general basin floor of 2.5 feet below MLLW to approximately 4.5 feet below MLLW under the I-5 bridge. Intertidal zone slopes to be created would range from 1-on-10 to less than 1-on-20, with most slopes steeper than 1-on-100. The West Basin would feature a four-acre California least tern nesting site with an elevation of 10 feet above MLLW. Three least tern nesting sites would be provided in the East Basin, as follows: (1) a 16-acre site near the park-and-ride lot south and east of the I-5 bridge; (2) a 12-acre site just west of the proposed freshwater marsh on the north shore of the lagoon; and (3) a 4-acre site incorporated into the proposed freshwater marsh levee; all least tern nesting sites would be at an elevation of 10 feet above MLLW. POSITIVE IMPACTS: Disposal of dredged lagoon sands would nourish the currently sand-depleted beaches. Important existing biological values within the lagoon would be protected, and certain biological values would be created or enhanced. Tidal influence would be restored to the lagoon. The project would mitigate damage caused by landfills in San Pedro Bay associated with the Port of Los Angeles 2020 Plan. Fish, waterfowl, and other wildlife habitat values gained from the enhancement project would be used to offset the habitat values lost as a result of landfill projects within the Los Angeles Harbor District. Salt marsh habitats, flood control, and health and safety within the area would be enhanced as well. Beach nourishment would increase the area's recreational value. A net contribution to the littoral drift would increase sand flow nourishment to beaches south of Carlsbad. NEGATIVE IMPACTS: Dredging and placement of beach nourishment would result in temporary turbidity within the lagoon and at the beach sites, respectively, and dredging could result in damage to archaeological and paleontological sites. Construction of the tidal inlet structure would also result in short-term disruption of bottom sediments, reducing water quality.

AN - 36392676; 2738 AB - PURPOSE: Implementation of navigational improvements within Canaveral Harbor, Brevard County, Florida is proposed. Canaveral Harbor lies on the east coast of Florida, approximately nine miles north of Cocoa Beach. The port is a major deep-draft harbor for water imports and exports in support of businesses located in Brevard, Orange, Osceola, and Seminole counties. The recommended plan would involve extending the civil works portion of the entrance channel to the 41-foot-contour over a width of 400 feet, deepening the inner channel from the Trident basin entrance to the middle turning basin to 40 feet and increasing its width to 400 feet, deepening the 1,200-foot-diameter portion of the middle turning basin to 39 feet, and deepening the first 1,800 feet of the west access channel to 39 feet and widening it to 400 feet. Approximately 1.0 million cubic yards of material, predominantly silt and clay, would be disposed in the Canaveral Harbor dredged material disposal site in the Atlantic Ocean, approximately nine miles southeast of the jetties. Recreational facilities associated with the project would involve development of the Lock Park and the Jetty Park fishing walkway. The Lock Park improvement plan would provide picnic shelters, a play structure, an open play area, a short boardwalk to a dock on an inner lagoon for nature observation, restrooms, and a parking lot. The estimated first cost of the project is $10.7 million, including $9.78 million for navigation improvements and $921,000 for recreational improvements. Annual costs of operation /maintenance of navigational channels and recreational facilities are estimated at $26,000 and $56,000, respectively. The project benefit-cost ratio is estimated at 2.1. POSITIVE IMPACTS: Enlargement of channels within the harbor would allow larger ships to carry more cargo at greater drafts, increasing the safety and efficiency of harbor operations. This would accommodate increases in bulk commodity handling by the harbor. Annual transportation cost savings redounding from the project would amount to $1.79 million. Annual recreation benefits would amount to $440,000. NEGATIVE IMPACTS: Dredging and disposal activities would result in short-term degradation of water quality and destruction of benthos.

Preparation date: June 26, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TRESTLE REPLACEMENT, NAVAL WEAPONS STATION EARLE, COLTS NECK, NEW JERSEY. AN - 36410250; 2679 AB - PURPOSE: Replacement of the 9,061-foot-long trestle connecting the trestle junction for the berthing and loading piers of Naval Weapons Station Earle (NWS Earle) to the mainland in Sandy Hook Bay, Monmouth County, New Jersey is proposed. NWS Earle is one of three weapons stations currently situated on the eastern seaboard of the United States. It was developed in 1943 to serve as a depot in the New York City area for supplying and loading ships with ammunition and other ordnance materials. The base is divided into three separate areas. The main station is located just south of Colts Neck, while the Waterfront and Chapel Hill areas are located adjacent to Sandy Hook Bay in Middletown Township. A government-owned railroad and highway, Normandy Road, connect all three. Four piers are located at the Waterfront area and are connected to the shore by the 9,061-foot trestle, constructed in the early to mid-1940s. The trestle is constructed of a reinforced concrete deck supported by 41,000 timber piles. The physical condition of the trestle complex has deteriorated, warranting concern about the operation of the system. The deterioration has been caused by freeze-thaw, action resulting in the breakdown of the concrete matrix. The proposed replacement trestle would be located on an alignment lying west of the existing trestle. The new trestle would carry two rail lines, two traffic lanes, and utility lines. The trestle would be constructed using 42-inch-diameter steel piles supporting a concrete slab deck. The majority of the trestle length could be constructed from the sea, using barge-mounted equipment, with a bent spacing of 60 feet; however, a section of the trestle, from the mainland to a water depth of four feet below mean low water, would require either land-based construction techniques or dredging to provide for barge access. It has been decided to avoid dredging and use the land-based techniques where necessary. The 2,124-foot-long section that would lie in shallow water could be built in an ""over-the-top'' fashion from land; due to the choice of this construction technique, this section would require bent spacing of 40 feet. The existing trestle would be left in place; some minor maintenance would be performed. POSITIVE IMPACTS: The new structure would replace an aging, superannuated trestle. As a result, currently mandated limitations in ordnance loads and activities associated with the trestle crossing would be lifted. An increase in hard substrate resulting from new pilings would have a long-term beneficial impact for sessile organisms and for fish as a result of increased protective habitat. NEGATIVE IMPACTS: Benthic habitat would be destroyed at each new piling site. Piling and other construction activities would result in temporary degradation of water quality in the immediate area.

AN - 36402978; 2674 AB - PURPOSE: Realignment of activities at Fort Huachuca in Cochise County, Arizona; Fort Devens in Worcester and Middlesex counties, Massachusetts; and Fort Monmouth in Monmouth County, New Jersey is proposed. The realignment would involve the transfer of personnel positions /authorizations and equipment between the installations. Overall the project would mean transferring the U.S. Army Intelligence School from Fort Devens to Fort Huachuca and consolidating the school with the U.S. Army Intelligence Center and School at Fort Huachuca, as well as transferring the U.S. Army Information Systems Command elements from Fort Huachuca, Fort Monmouth, and Fort Belvoir to Fort Devens. Primarily military positions and some civilian positions would be transferred from Fort Devens to Fort Huachuca. Primarily civilian positions and some military personnel positions would be transferred from Fort Huachuca to Fort Devens. Some military and civilian personnel would be transferred from Fort Monmouth and Fort Belvoir to Fort Devens. As a result, there would be an increase in military positions and a decrease in civilian positions at Fort Huachuca and a decrease in military positions and an increase in civilian positions at Fort Devens. There would be a reduction in both military and civilian positions at Fort Monmouth. In addition to the realignment of personnel positions, the proposed action would require the renovation of present facilities and the construction of new facilities at Fort Huachuca and Fort Devens. POSITIVE IMPACTS: Army educational activities associated with intelligence and information would be consolidated, increasing the efficiency of the Army mission in these areas while decreasing expenditures. Increases in off-post civilian personnel associated with Fort Devens would provide a substantial boost to the local economy, increasing regional employment, regional sales volume, and regional income. NEGATIVE IMPACTS: A reduction in wages and direct expenditures at Fort Huachuca would result in a significant economic impact on the local area. Lesser economic impacts would affect Fort Monmouth. The off-post rental housing market in particular would be affected. Additionally, there would be a potential shift of school children to on-post schools. Increased training activities at Fort Huachuca would have impacts on cultural and biological resources. LEGAL MANDATES: Base Closure and Realignment Act of 1988 (P.L. 100-526).

Preparation date: June 22, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - AMITE RIVER AND TRIBUTARIES STUDY, COMITE RIVER BASIN, LOUISIANA. AN - 36406010; 2743 AB - PURPOSE: Implementation of a flood control project to protect residents and property within the Amite River Basin of Louisiana is proposed. The study area, which is largely covered with forest and agricultural land, encompasses approximately 2,200 square miles in southeastern Louisiana and southwestern Mississippi. Urban and other developed land comprise 12 percent of the land use. Major urban centers in the study area include Baton Rouge, Baker, Zachary, Gonzales, Sorrento, and Denham Springs. The tentatively selected flood control plan would involve excavation of a 12-mile diversion channel from the Comite River to the Mississippi River and construction of a diversion structure, two stage control structures, and two levees. The diversion channel would begin at mile 19 on the Comite River above its confluence with the Amite River and would run generally west between the cities of Baker and Zachary to the head of the Lilly Bayou Watershed; eight miles of channel excavation would be required, while the remainder of the diversion would use the Lilly and Cooper bayous. A levee would be constructed along the southern bank of the diversion channel from the diversion structure to the diversion channel stage control structure. The Comite River stage control structure and containment levee would create the stages necessary to divert flood flows to the diversion channel. The diversion channel stage control structure would reduce flood velocities within the diversion channel; the structure would be a trapezoidal weir crest. Mitigation features of the plan would consist of planting trees on the cleared land within the levee containment area, planting of trees on a portion of the disposal area, and acquisition of lands in an oxbow area of the Amite River between Denham Springs and Port Vincent. Perpetual channel rights-of-way would be acquired on 607 acres along Lilly and Cooper bayous. The plan would include upgrading two gauging stations and the installation of six gauging stations in the basin to assist in flood prediction. The first cost of the project is estimated at $62.4 million, with annual charges of $6.86 million. The benefit-cost ratio for the project is estimated at 1.5. POSITIVE IMPACTS: Average annual damages to existing developments within the Amite River Basin would decline by 27 percent. In the Comite River Basin, average annual damages would be reduced by 65 percent. Average annual damage reduction in individual subbasins would range from less than 1 percent to more than 90 percent. Average annual benefits redounding from the project as a whole would amount to $10.3 million. The diversion channel would create additional low-grade aquatic habitat. NEGATIVE IMPACTS: Flood control structures and flood control, itself, would result in a loss of 435 acres of bottomland hardwood and 29 acres of upland hardwood habitat per year. Construction and excavation activities would result in short-term increases in turbidity and temperature levels in receiving flows, with decreased dissolved oxygen levels near construction sites. Wintering waterfowl would suffer from a loss of 5,450 acre-days of winter flooding of bottomland forests each year. Recreational hunter losses would amount to 294 person-days per year, although these would be mitigated. A total of 30 homes, churches, and businesses would be relocated.

AN - 36401507; 2742 AB - PURPOSE: Implementation of a flood control project to reduce damages in the vicinity of Rossville, Kansas is proposed. The project, which would be designed to contain the overflows from Cross Creek, would consist of relocating the channel 0.25 mile west of Rossville and constructing a trail levee parallel to the new channel. A cutoff channel, approximately 3,800 feet long and 26 feet deep, would reduce the maximum flood elevation by allowing flows to pass more efficiently and would prevent the proposed levee from inducing higher flood elevations. The new channel would divert flows from approximately 6,900 feet of the existing stream channel, shortening the total length of Cross Creek by approximately 3,100 feet. The 9,500-foot-long trail levee would be tied to high ground north of town and trail off at a location adjacent to the existing channel south of town. The top-of-levee elevation at the upstream tie-off north of town is 938.26 feet national geodetic vertical datum (NGVD); the top-of-levee elevation decreases to 935.00 feet NGVD at bridge crossings and to 932.27 feet NGVD at the downstream tie-off south of town. Three interior drainage subbasins would be developed. A Union Pacific Railroad Bridge would be relocated as part of the project, and the U.S. Highway 24 bridge would be reconstructed. Mitigation measures associated with the plan would include permanent acquisition of 12.6 acres of riparian timber and oxbow plus 13 acres of cropland, in addition to other lands specified as required for project purposes, obtaining additional temporary easements on 11.6 acres of land inside the levee north of the highway for disposal of the remaining excavated material, and construction specifications requiring that there be as little clearing as possible. Project facility construction would require the purchase of approximately 68.7 acres of land in fee or on permanent easement. The estimated cost of the project is $7.15 million at October 1989 price levels, and the benefit-cost ratio is estimated at 1.13. The annualized cost of the project is $682,000. Annual operation and maintenance costs are estimated at $5,500. POSITIVE IMPACTS: Project facilities would protect Rossville against the 500-year-frequency flood on Cross Creek. Human health and safety as well as real property would be protected against flooding. Annual project benefits would amount to $771,000. Community decline within the developed portion of the floodplain would be prevented. Approximately 528 acres of farmlands would also be protected. NEGATIVE IMPACTS: Water flows would be eliminated in 2,900 feet of channel and reduced in 4,000 feet of old channel. The aquatic environment in the existing stream meander would be totally lost due to filling of the isolated meander loop with excess earthen material from excavation of the new channel.

AN - 36405321; 2607 AB - PURPOSE: Fort Dix, in Burlington, Mercer, Monmouth, and Ocean counties, New Jersey, has been proposed for realignment to semiactive status. This action would involve associated Army facilities, including Fort Bliss, Texas; Fort Jackson, South Carolina; Fort Knox, Kentucky; Fort Lee, Virginia; and Fort Leonard Wood, Missouri. The new status of the base would involve the transfer of entry-level training functions from Fort Dix to other Army installations located within the continental United States. More specifically, the plan would (1) transfer basic training at Fort Dix to Fort Knox, Fort Leonard Wood, and Fort Jackson; (2) consolidate basic training at Fort Bliss with basic training at Fort Jackson; (3) consolidate Fort Dix motor vehicle operator training at Fort Leonard Wood; (4) consolidate Fort Dix and Fort Leonard Wood light-wheeled vehicle mechanic training at Fort Jackson; (5) consolidate Fort Benjamin Harrison, Indiana administrative and legal specialist training at Fort Jackson; (6) transfer Fort Jackson personnel specialist training to Fort Benjamin Harrison; (7) consolidate Fort Jackson supply specialist training at Fort Lee; and (8) consolidate Fort Dix and Fort Jackson food service specialist training at Fort Lee. In addition to the changes in training, each installation would either gain or lose personnel assigned to the Health Services Command and tenant activities located at the installations. Tenant activities occupy real estate at the various forts but are under the direction or command of another or higher authority. POSITIVE IMPACTS: Plan implementation would increase the availability of training areas at Fort Dix to support active and reserve training in the northeast. The combat readiness of troops trained at the facility would be assured. The local economy associated with Fort Knox and Fort Lee would benefit somewhat, while significant benefits would redound to the economies of communities associated with Fort Jackson and Fort Leonard Wood. NEGATIVE IMPACTS: Social and economic conditions in the local community associated with Fort Dix would decline significantly. Lesser socioeconomic impacts would occur in the local community associated with Fort Bliss. LEGAL MANDATES: Base Closure and Realignment Act of 1988 (P.L. 100-526).

Preparation date: June 8, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE D (PAGE AVENUE EXTENSION), BENNINGTON PLACE WESTERLY TO ROUTE I-70 OR ROUTE 40, SAINT CHARLES AND SAINT LOUIS COUNTIES, MISSOURI. AN - 36405612; 2655 AB - PURPOSE: The construction of a freeway, including a crossing of the Missouri River, within Saint Louis and Saint Charles counties, Missouri is proposed. Under the proposed action, Page Avenue would be extended from its present terminus at Bennington Place immediately west of Route I-270 in Saint Louis County, proceed across the Missouri River to Route 94 in Saint Charles County, and then continue on either Route I-70 or Route 40/61, a distance of approximately 19.4 miles. The preferred alternative, the Red Alignment, would be a 10-lane limited-access highway with a 22-foot-wide median from Bennington Place to the Hemsath Road intersection with Route 94. As part of the Red Alignment, from Hamsath Road to Route N, Route 94 would become an eight-lane limited-access highway with a 22-foot-wide median. One-way outer roads would be provided as service roads. From Route 94 to either Route 70 or Route 40/61, the improvements would provide a four-lane, limited-access highway with a 70-foot-wide median. Grade separations for Bennington Place would be constructed over the Page Avenue Extension and the west half of a diamond interchange. Grade separations would also be provided at Amiot Drive and Seven Pines Drive, the River Valley Road, Route 94, Motherhead Road, and Henke Road. A bridge of approximately 2,800 feet would span Creve Coeur Lake, Creve Coeur Creek, and associated wooded bottomland. The bridge over the Missouri River would extend 3,500 feet and provide ten 12-foot travel lanes, four ten-foot shoulders, and a three-foot-wide median barrier. Interchanges would be provided in the vicinity of Creve Coeur Mill Road, Upper Bottom Road, Route 94, Route N, Route K, Bryant Road, and Route 40. All existing intersections at Kisker Road, Saint Peters Road, Howell Road, old Route 94, and Dingledine Road would be rerouted on one-way outer roadways. POSITIVE IMPACTS: The chronic traffic congestion at Missouri River crossings between Saint Louis and Saint Charles counties would be relieved, and concurrent reductions in energy costs and improvement of air quality would be effected. Additional benefits would be improved traffic flow conditions within Saint Charles and Saint Louis counties on secondary roads and on routes 40/61, I-70, and I-270. The development would continue to occur throughout Saint Charles County; and along the proposed alignments, induced development would take place at interchanges and along outer roads. NEGATIVE IMPACTS: The rights-of-way requirements would result in the displacement of prime farmland, relocation of residences and commercial establishments, traversal of the Missouri River floodplain and associated loss of wetland, and removal of public parkland.

Preparation date: June 7, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 29, MADISON HEIGHTS BYPASS, CITY OF LYNCHBURG AND AMHERST COUNTY, VIRGINIA. AN - 36408989; 2663 AB - PURPOSE: A highway improvement project along Route 29 within the city of Lynchburg and Amherst County, Virginia is proposed. The project would begin in the southern portion of Lynchburg and terminate just south of the town of Amherst. The typical cross-section would consist of four to six lanes of median-divided limited-access roadway on new alignment on a 190-foot-wide minimum rights-of-way. Three build alternatives are under consideration. All three share a common beginning point in Lynchburg, but have different termini south of Amherst. Alternative ""Line E'' would begin at existing Route 460 near its intersection with Route 501 in the southern portion of Lynchburg and cross the Norfolk & Western Railway and Holcomb Path Road before turning northeasterly to bridge the James River west of the Lynchburg/Campbell County line. It would then proceed northerly across Route 672, the Route 210 connector, and the Route 130 connector in Amherst County; continue to the north, passing under Route 624 with a partial interchange; and connect into existing Route 29 near its intersection with Business Route 29 south of the town of Amherst. Alternative ""Line M'' would follow the same beginning alignment as Alternative ""Line E'' but would continue in a northwesterly direction, remaining to the east of Route 671 and tying into Route 29 near its intersection with Route 697 at the community of McIvor. Alternative ""Line W'' would follow the same initial alignment as Alternative ""Line E'' but would pass under the existing Route 29 expressway north of its interchange with Route 210, turn northerly to interchange with Route 130, cross Routes 657, 636, and 655, and terminate with an interchange at existing Route 29 south of the community of Faulconerville. ""Line E'' and ""Line M'' alternatives would require some relocation of Routes 210 and 130. POSITIVE IMPACTS: Serving the north-south traffic corridor bypassing the community of Madison Heights and Lynchburg, the project would reduce truck traffic from a congested commercial area and provide a bypass for through travelers. Movements of emergency and rescue equipment in the area would be expedited due to reduced congestion. The project would be consistent with the Lynchburg Area Year 2000 Transportation Plan, 1986 Central Virginia Planning District Technical Advisory study on transportation, and transportation goals of Amherst County. NEGATIVE IMPACTS: Rights-of-way requirements would displace 53 to 88 families and 1 to 6 businesses and convert 124 to 873 acres of farm, wooded, and open land to highway use. From 2.03 to 2.40 acres of wetlands would be displaced. Alternative ""Line W'' would encroach on an historic district, while the ""Line E'' and ""Line M'' alternatives would displace an historic structure.

Preparation date: June 5, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WASHINGTON BYPASS FROM I-95 IN VIRGINIA TO I-70 AND U.S. 50 IN MARYLAND. AN - 36408339; 2650 AB - PURPOSE: Construction of a fully controlled-access freeway to provide a U.S. 50 bypass of the District of Columbia region of Virginia and Maryland is proposed. The Washington bypass study area is extensive, including more than 5,100 square miles covering 120 miles from north to south and 90 miles from east to west. Both an Eastern Bypass and a Western Bypass are under consideration. For the Eastern Bypass corridor, the southern terminus would be the junction of Virginia (VA) 207 and Interstate 95 (I-95) in Caroline County, Virginia, while the northern terminus would be the I-695 /Maryland (MD) 3 interchange in the Baltimore, Maryland area. For the Western Bypass corridor, the southern terminus would be the intersection with I-95 in Stafford County, Virginia, while the northern terminus would be I-70 from U.S. 15 in Frederick, Maryland to just east of MD 27 near Mt. Airy, Maryland. Three distinct alternative alignments and one composite alignment are under consideration in each corridor. The freeway would have a design speed of 70 miles per hour. For analysis purposes, the land width was assumed to be 12 feet, with a maximum grade at a 3-degree maximum curvature to provide sufficient space for construction of rail transit or to accommodate exclusive high-occupancy vehicle or bus lanes for carpools and vanpools. The assumed rights-of-way used for the analysis was located in the center of a corridor 0.8 mile wide. Final alignments could be shifted in the 0.8-mile corridor in order to avoid sensitive areas or mitigate impacts. The rights-of-way assumed for all build alternatives would be 450 feet on new location and 300 feet where the facility would be constructed on an existing roadway. Freeway access would be controlled via grade separations and interchanges. The number of lanes would vary by alternative, based on land use and traffic projections and engineering. The estimated cost of the project ranges from $1.4 billion to $1.8 billion, depending on the alternative chosen. POSITIVE IMPACTS: In addition to providing another bypass of the Washington, D.C. area, the freeway would add capacity to the regional system, improve truck and traffic safety, and provide improved facilities for both through and local traffic. Area employment rolls would increase during and after construction of the freeway. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 119 to 264 residences and up to 99 nonresidential structures, as well as 192 to 2,075 acres of farmlands. The western bypass would affect two to four recreational/preserve areas. From 147 to 607 acres of wetlands, 143 to 504 acres of floodplains, and 52 to 169 streams would be crossed. One to seven sites eligible for inclusion in the National Register of Historic Places would be damaged. Construction of the freeway would result in intensive growth and development pressures in the vicinity of interchanges due to increased accessibility. Unplanned development would occur in Caroline, King George, and Charles counties for the Eastern Bypass corridor alternatives and Stafford, Fauquier, Prince William, Loudoun, Montgomery, and Frederick counties for the Western Bypass corridor alternatives.

Consequently, movement of sediment bound contaminants within a project is directly linked to the movement of sediment. Sediment-water interactions play a major role in determining whether contaminants remain with the sediments or are released from them. While the scientific principles underlying these interactions are fairly well understood, the ability to quantify them and then apply this knowledge to analyze and predict the effects of contaminated sediments on water quality Corp of Engineers (CE) reservoir projects is lacking. It has been determined from recent studies that many CE reservoirs are experiencing problems resulting from contaminants in project waters and sediments. Eighteen percent of 442 CE reservoir projects were reported to have problems with organic contaminants. An identical percentage of these projects reported difficulties with pH. Thirty-three percent of the projects had problems with metals other than iron and manganese, primarily cadmium, copper, mercury and lead. Problems with manganese and iron occurred in 24-25% of the projects. The US Army Engineer Waterways Experiment Station (WES) is conducting studies to determine: adsorption/desorption rates for major contaminants; the influence of sediment concentration on equilibrium distribution coefficients and adsorption/desorption kinetics; effects of particle composition; the effects of site specific conditions and environmental factors on contaminant-sediment-water interactions; and the significance of microbial transformations and mobilization processes on contaminated levels in reservoirs. The results will assist in describing contaminant movement in reservoirs.

AN - 36405351; 2669 AB - PURPOSE: Designation of a permanent ocean disposal site is proposed for material dredged from the Mermentau River-Gulf of Mexico Navigation Channel of Louisiana, where an east-west sandbar occurs. The Mermentau River is an important entrance to and from Grand Chenier, Louisiana and the Gulf of Mexico. The preferred alternative would involve permanent designation of the interim site, which has been used for approximately 20 years. The site is located at the gulfward end of the Mermentau River. Boundary coordinates of the preferred site are 29 degrees, 43 minutes, 12 seconds north latitude (N); 93 degrees, 53 seconds west longitude (W); 29 degrees, 43 minutes, 21 seconds N; 93 degrees, 1 minute, 23 seconds W; 29 degrees, 42 minutes, 27 seconds N; 93 degrees, 53 seconds W; 29 degrees, 42 minutes, 27 seconds N; 93 degrees, 1 minute, 23 seconds W. Approximately 500,000 cubic yards of dredged material are disposed during each disposal operation. Disposal generally occurs once every two to three years. POSITIVE IMPACTS: Dumping site designation would allow for continued maintenance of the Mermentau River-Gulf of Mexico Channel. As a result, the channel could continue to provide access for commercial traffic carrying crude petroleum, manufactured products, and fuel oil; vessels involved in shrimp, crab, and other fish harvesting; and support vessels for offshore oil and gas activities. NEGATIVE IMPACTS: Dumping of material at the proposed site would result in the temporary alteration of site topography via mounding, smothering of benthos at the site, and temporary disturbance of the water column due to turbidity and chemical releases, as well as in the reduction of dissolved oxygen levels. Temporary increases in copper, mercury, and other pollutants could occur immediately after disposal operations.

Preparation date: May 30, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - I-25, 49TH AND 50TH AVENUE INTERCHANGES, DENVER AND ADAMS COUNTIES, COLORADO. AN - 36404140; 2645 AB - PURPOSE: Improvement of interchanges connecting Interstate 25 (I-25) with 49th and 58th avenues in Denver and Adams counties, Colorado is proposed. The project has seven major components: (1) closing the I-25/49th Avenue interchange; (2) constructing a new I-25 southbound off-ramp to 48th Avenue as partial replacement access for closing the I-25/49th Avenue interchange, and not replacing the southbound on-ramp and northbound on- or off-ramps; (3) reconstructing the I-25/58th Avenue interchange, including the widening of 58th Avenue between Broadway and new Logan Court, shifting the centerline of I-25 approximately 60 feet to the east at 58th Avenue and adding a continuous acceleration and deceleration lane on northbound and southbound I-25; (4) constructing new Logan Court between 56th and 58th avenues, including a new signalized intersection, and reconstructing the main entrance to the Denver Merchandise Mart at 58th Avenue and new Logan Court; (5) removing the traffic signal at 58th Avenue/Logan Street and restricting turning movements to right-in-right-out (except for a left to Logan Street north of 58th Avenue); (6) upgrading the west frontage road (Bannock/Broadway) between 48th and 60th avenues, including improvements to 48th Avenue between Bannock and Broadway; and (7) changing the east frontage roads (Lincoln, Broadway, and Acoma streets), including the closing of Lincoln Street between 56th and 57th avenues. Costs of the project are estimated at $21 million for construction and $3 million for rights-of-way acquisition. POSITIVE IMPACTS: The safety and capacity of the affected I-25 interchanges would be improved. Removal of the 49th Avenue interchange would eliminate conflicts with the I-25/I-70 interchange immediately to the south; the latter interchange is scheduled for reconstruction to improve its safety and capacity. Removal of the 49th Avenue interchange and replacement of the 58th Avenue interchange would also allow for the provision of high-occupancy vehicle lanes on I-25. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of two residences, three businesses, and one public facility. Landscaped areas and business parking areas would be affected along the west and east frontage roads and along 58th Avenue between Broadway and new Logan Court. Some wetlands would be lost. Redistributing traffic affected by the closure of the 49th Avenue interchange to other interchanges along I-25 and I-70 would increase traffic on some residential streets in the Globeville neighborhood. Travel distances and time for out-of-direction traffic accustomed to using the 49th Avenue interchange would increase significantly. The area affected by the turning restrictions at 58th Avenue and Logan Street would also experience an increase in out-of-direction travel distances and time. Access to some businesses and homes near the existing 49th Avenue interchange and at 58th Avenue and Logan Street would be less convenient. Noise levels affecting some sensitive receptors would increase throughout the project areas. Properties containing hazardous wastes may be encountered.

Preparation date: May 25, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NC 226, SPRUCE PINE BYPASS, FROM US 19E TO MINPRO, MITCHELL COUNTY, NORTH CAROLINA. AN - 36400812; 2657 AB - PURPOSE: Construction of a western bypass around the town of Spruce Pine on North Carolina 226 (NC 226) in Mitchell County, North Carolina is proposed. The alignment of existing NC 226 in the vicinity of Spruce Pine is substandard, with steep grades and sharp curves. The existing two-lane pavement is narrow, with limited shoulder width for much of its length in the study area. The southern terminus of the project would be southwest of Spruce Pine along US 19E in the vicinity of its intersection with State Route (SR) 1152 (Deer Park Lake Road). The bypass would extend from US 19E to the project's northern terminus, a northwesterly point approximately 1.4 miles north of the intersection of SR 1151 (Minpro Road) and existing NC 226. The proposed facility would be approximately 1.5 miles long and would be a four-lane, partially controlled-access rural highway with a four-foot flush median. A bridge would be constructed across the North Toe River and would also cross the CSX Transportation Railroad immediately adjacent to the river. Various alternatives were considered, including the Transportation Systems Management Alternative, the Mass Transit Alternative, the Improved Roadway Alternative, the Build Alternative, and the No-Build or ""Do Nothing'' Alternative. Only the Build Alternative would meet the safety and capacity requirements of the project. Within the Build Alternative, there are four build alternates. Alternate 1 would most closely follow the proposed bypass alignment in the 1977 Major Thoroughfare Plan; it would extend approximately 1.58 miles and would require a bridge approximately 480 feet long. It would also require a 1,760-foot permanent connector for SR 1152, as well as an 1,140-foot temporary connector to provide access during construction. Alternate 1A, which would represent a modification of Alternate 1, would differ only in the area just north of the southern terminus; it would extend approximately 1.46 miles and require a bridge approximately 480 feet long. It would also require a 1,690-foot permanent connector to SR 1152. Alternate 2 would extend approximately 1.44 miles, and would require a bridge approximately 720 feet long and a 440-foot overpass of SR 1152. Alternate 4 would also extend 1.44 miles and would require a bridge approximately 720 feet long and construction of a 260-foot overpass at SR 1152. The estimated costs of alternates 1, 1A, 2, and 4 are $8.7 million, $11.0 million, $11.9 million, and $15.0 million, respectively. POSITIVE IMPACTS: Bypass construction would improve travel safety on NC 226 in the study area, improving the transportation system linkage, the existing level of traffic service provided, and social and economic conditions. Long-distance and regional traffic could be removed from local streets in Spruce Pine. NEGATIVE IMPACTS: Rights-of-way requirements would result in the relocation of 1 to 13 residences, up to 3 businesses, and 5 acres of prime farmland. From 11 to 19 acres of farmland of statewide importance would be affected as well. Traffic-generated noise within the corridor would impact several residential areas, with up to five residences being affected by noise levels in excess of federal standards; one to six residences would experience substantial increases in traffic-related noise levels. One wetland area could be impacted indirectly due to sediment in runoff. Floodplains associated with the North Toe River would be traversed by any alternative; fill placement in the floodway fringe would range up to 0.3 acre. Relatively minor impacts to pastureland, water quality, terrestrial ecology, wildlife resources, and fishery resources would occur.

Preparation date: May 24, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED IMPROVEMENT OF M-53 FROM 27 MILE ROAD IN MACOMB COUNTY, NORTHERLY APPROXIMATELY 24.7 MILES TO BOWERS ROAD IN LAPEER COUNTY, MICHIGAN. AN - 36405574; 2653 AB - PURPOSE: Reconstruction of approximately 24.7 miles of state trunkline Michigan 53 (M-53) is proposed from 27 Mile Road in Macomb County northward to Bowers Road in Lapeer County, Michigan. The recommended alternative would involve staged construction of a limited-access roadway on new location over a 7.7-mile segment between 27 Mile Road and 34 Mile Road and implementation of low-capital improvements to existing M-53 between 34 Mile Road and Bowers Road. The freeway segment would traverse most of Washington Township and the southern third of Bruce Township in Macomb County, while the low-capital improvements would be implemented throughout the remaining portion of Bruce Township and all of Almont and Imlay townships in Lapeer County. The first stage in the 7.7-mile section, identified for staged construction as a bypass around Romeo, would involve acquisition of all limited-access rights-of-way required for the construction of the freeway segment to 34 Mile Road. Initial construction would be limited to building the future southbound roadway, excluding interchanges and grade separations, with an exception at 29 Mile Road. A grade separation would be provided at 29 Mile Road as part of the first stage. First stage construction would be opened to traffic as a two-lane, two-way roadway. Second stage construction for the eastern bypass of Romeo would provide the northbound roadway, without interchanges and grade separations, and would convert the facility to a boulevard cross-section. The third stage would involve completion of the bypass as a freeway. The second and third stages could be completed simultaneously. Upon completion of the final stage, the limited-access roadway would be constructed to rural freeway standards within a 368-foot minimum rights-of-way. In addition to six grade separations and two interchanges, the bypass would include a bridge crossing East Pond Creek. Low-capital improvements to existing M-53, between 34 Mile Road and Bowers Road, would primarily consist of widening some of the major intersections, such as Dryden Road, to provide right- and/or left-turn lanes and adding paved shoulder ribbons where none presently exist. None of the low-capital improvements would require new rights-of-way. The estimated costs of the freeway and the low-capital improvements are $33.2 million and $1.65 million, respectively. POSITIVE IMPACTS: Construction of the freeway facility would remove through traffic from the existing route, relieving congestion within the villages of Romeo and Almont. The freeway would increase accessibility of special interest centers and recreational areas north of Imlay City and would reduce vehicle operation costs and travel times in the area. The interchange at 29 Mile Road would significantly improve access to and from Powell Junior High School and the associated athletic field. NEGATIVE IMPACTS: Rights-of-way for the freeway bypass would require acquisition of 10 residential units and 5 businesses, 150 acres of farmlands, and 80.2 acres of wetlands. Additional farmland would be displaced due to wetland mitigation requirements and development induced by the freeway. A total of 14 wetlands would be affected by losses. The freeway would traverse the floodplain of one stream. Noise levels within the freeway corridor would increase significantly. One old gasoline storage tank located near 29 Mile Road and a potential hazardous waste site at 28 Mile Road would require removal of wastes to a type II landfill.

AN - 36400639; 2620 AB - PURPOSE: Construction of two 393-megawatt (MW) (net) pulverized coal-fired electric generating units is proposed by Old Dominion Electric Cooperative at a new plant site near Clover in Halifax County, Virginia. The 848-MW gross (786-MW net) pulverized coal-fired steam electric generating station would be located on a 1,760-acre site along the Roanoke River directly across from Charlotte County. Major station facilities would include two 424-MW gross (393-MW net) coal-fired units with expected startup dates of 1994 and 1995; two 14.6-meter (48-foot)-high, 232-meter (762-foot)-long, and 16-meter (54 foot)-wide mechanical draft cooling towers; two 134-meter (440-foot)-high stacks; boilers designed to limit oxides of nitrogen to meet a 0.32 pound per million Btu emission limit; a chemical wastewater treatment system; a wet-flue gas desulfurization scrubbing system; a fabric-filter baghouse; dry fixation facilities for treatment of flue gas desulfuration wastes and coal ash; an on-site sludge disposal facility; a 140,000 pounds of steam per hour oil-fired auxiliary boiler and associated 473,125-liter (125,000-gallon) oil storage tank; and a loop-track rail spur from an existing Norfolk Southern Railway line. Stack emissions would be controlled by limestone scrubbers, a fabric-filter baghouse, and boiler design. Condenser cooling would be accomplished by the use of mechanical draft cooling towers. Plant water would come from the Roanoke River. An on-site water reservoir with a 30-day capacity would supplement plant water supply during periods of low river flow. Two five-kilometer (three-mile), 230-kilovolt transmission lines would interconnect the station to the existing transmission grid. Coal would be purchased from southwestern Virginia, eastern Kentucky, and/or West Virginia and transported via rail by the Norfolk Southern Railroad. Trains would be routed to South Boston, Virginia and reconfigured for delivery to the Clover plant in either half or whole unit train segments. It is possible that Virginia Power Company of Richmond will obtain an undivided ownership in 50 percent of the proposed 786-MW facility. POSITIVE IMPACTS: Electric power provided by the new units would replace an expiring 300-MW purchase power contract, answer the overall need for additional generating capacity, and provide for future projected capacity of the 12-member Old Dominion Electric Cooperative. Construction and operation of the facility would generate jobs, taxes, and other economic benefits. NEGATIVE IMPACTS: Levels of concentrations for sulfur dioxide, nitrogen oxides, and particulates would increase in the vicinity of the site, but would remain within government standards. Wastewater effluent would be discharged into the Roanoke River. Construction activities would require removal of 275 cubic meters of river bottom material. Site activities would result in the disturbance of 662 acres; most of this land has been used for agricultural purposes. Cultural resources, some of which are eligible for inclusion in the National Register of Historic Places, would be disturbed during site development.

Preparation date: May 19, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED PERMIT APPLICATION, BLACK MESA-KAYENTA MINE, NAVAJO AND HOPI INDIAN RESERVATIONS, ARIZONA. AN - 36407905; 2610 AB - PURPOSE: Issuance of permits to consolidate all Peabody Coal Company-owned and -operated mining and mining-related activities within the Black Mesa-Kayenta mine in Arizona is proposed. The permits would allow for surface coal mining and reclamation activities during the life of the mine. Currently, the Black Mesa-Kayenta mine, located approximately 125 miles northeast of Flagstaff and 10 miles southwest of Kayenta, Arizona, consists of two separate but adjacent mining operations. The two units are the Black Mesa mine, which produces approximately 5 million tons of coal per year, and the Kayenta mine, which produces approximately 7 million tons per year. The proposed permit area would cover 62,753.34 acres of Hopi and Navajo tribal lands. The applicant would produce 292 million tons of coal from the new disturbance area between 1986 and 2011. Mining and reclamation activities would continue through 2023 (the proposed life of the mine). The applicant has previously been awarded two permits to mine coal at the mining complex. Between 1970 and the end of 1985, mining activities disturbed approximately 6,444 acres within these two permit areas. The proposed federal permit would combine the previously issued permits under one permit and authorize the applicant to disturb an additional 13,787.4 acres throughout the remaining life of the mine and to upgrade a number of the existing mine-related facilities to meet current federal performance standards. Coal would continue to be extracted using the dragline and truck-and-shovel open-pit methods and would be processed using existing in-place facilities owned and operated by the applicant within the new permit area. Processed coal would be transported from the Black Mesa Mine to the Mohave Generating Station via an existing slurry pipeline owned and operated by the Black Mesa Pipeline Company and from the Kayenta Mine to the Navajo Generating Station via the existing Black Mesa and Lake Powell Railroad. POSITIVE IMPACTS: New activities authorized under the permit would result in the production of 292 million tons of coal between 1986 and 2011. The applicant, which employs 1,000 persons at the mine, would continue to provide employment to local residents; 90 percent of the current employees are Native Americans. Regional power needs would continue to be met. NEGATIVE IMPACTS: Vegetative diversity would be impacted severely due to the conversion of 9,046 acres of pinyon-juniper woodlands, 4,485 acres of shrubland, and 87 acres of other vegetation to grassland. Major socioeconomic impacts would occur to the Hopi Tribe's fiscal status and ability to provide human services over the long term. Mining activities would create fugitive dust, displace grazing land, and damage cultural resources. Outcrop and other topographic features characterizing the mine sites would be leveled, and sacred ceremonial sites could be degraded. Cropland within the area would be displaced, and formation of acid and other toxins would degrade soil quality and reduce the vegetative carrying capacity of the affected lands. Surface and groundwater levels could decline due to pumping of the N-aquifer. Wildlife habitat, including that of certain threatened or endangered species, could be affected. The population base of the Hopi and Navajo reservations could be changed. Regional transport and recreation facilities could be stressed.

AN - 36408831; 2601 AB - PURPOSE: Approval of an airport layout plan is proposed to allow development of two new parallel runways and associated facilities at Standiford Field Airport in Louisville, Jefferson County, Kentucky. In addition to the parallel runways, the project would involve construction of parallel, full-length taxiways on the airfield side of both runways. Provisions would be made for future taxiways on the outside of the parallel runways, but these would not be constructed as part of the proposed improvement plan. Runway 11/29 would continue to function as the crosswind runway. Sections of Runway 1/19 would become taxiways. The Air Traffic Control Tower would be relocated. The location of the site would provide ""line of sight'' to all aircraft movement areas of the airfield. The project would also include installation of Category I instrument landing system (ILS) facilities on the north ends and Category II ILS facilities on the south ends of each new runway, along with runway and approach lighting systems. A new Aircraft Rescue and Firefighting Facility would be developed, as well as a new Airport Maintenance Facility. The U.S. Postal Service would be relocated to the Highland Park Urban Renewal Area, and the National Weather Service facilities would be relocated offsite. Crittenden Drive (Kentucky 1631) would be relocated to the west of the new west runway; however, its reconstruction would be delayed at least 10 years. POSITIVE IMPACTS: Additional airport capacity would be provided to an expanding facility to ensure its operational integrity in the near and long terms. Improvement of the airport would contribute to the local and regional economies, supporting 8,000 construction jobs during development and generating 27,000 permanent new jobs associated with airport operations and airport-related business activities. NEGATIVE IMPACTS: Approximately 40 businesses, 150 residential properties, and 1 church would require relocation, and some land would be taken from the ongoing Urban Renewal Program in four adjacent neighborhoods. Lowell School and Grove Park, including the Highland Park Community Center, would be displaced. Actions in the South Highland Park area would result in the disruption of archaeological sites. An historic house, potentially eligible for inclusion in the National Register of Historic Places, would be subject to aircraft noise. Two woodlot biotic communities and two wetland communities would be lost, and a portion of Duck Spring Branch would require relocation. Major utility relocation would include moving the Louisville Gas and Electric substation on the west side of Crittenden Drive and possible relocation or reconstruction of a 60-inch water main and an underground fiber optic cable. The latter two utilities cross airport property. A portion of the Kentucky Air National Guard would be taken. Hazardous waste sites would lie within the construction area. Approximately 15,000 persons reside within the area significantly affected by aircraft noise.

Preparation date: May 14, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CENTRAL ARTERY (INTERSTATE 93)/THIRD HARBOR TUNNEL (INTERSTATE 90) PROJECT, BOSTON, MASSACHUSETTS (DRAFT SUPPLEMENT 2 TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1985). AN - 36406942; 2652 AB - PURPOSE: Extension of the Interstate 90 (I-90)/I-93 freeway system from its current terminus in Boston, Massachusetts is proposed. The project, which would be known as the Central Artery (I-93)/Third Harbor Tunnel (I-90), would be located entirely in the city of Boston in Suffolk County. This draft supplement to the final environmental impact statement of August 1985 describes the proposed action and design modifications to the proposed action currently under consideration, the alternatives analysis conducted for three major design refinements and for the materials disposal program, and project impacts on parklands and historic and archaeological resources. Several technical appendixes are also included. The proposed action consists of approximately seven miles of new and reconstructed roadways. More specifically the project would involve: (1) construction of a widened, mostly undergound I-93 from just north of its interchange with Route 1 in Charlestown to just south of the Massachusetts Avenue interchange (I-93 is referred to as the Central Artery north of Kneeland Street and as the Southeast Expressway south of Kneeland Street); (2) construction of an extension of I-90 via a Seaport Access Road and Third Harbor Tunnel to Logan Airport in East Boston, with a connection to Route 1A; (3) construction of an extended frontage road system parallel to I-93 northbound and southbound from Causeway Street to just past Southampton Street; and (4) construction of a South Boston Bypass Road, most of which would be in an existing railroad rights-of-way, to connect the Southeast Expressway (I-93) directly to the Seaport Access Road (I-90) and a relocated Massport Haul Road in South Boston. The I-90 extension would begin at the present terminus of the Massachusetts Turnpike (I-90) at the Southeast Expressway and proceed eastward, mainly in tunnel, through South Boston, under Boston Harbor, and into Logan Airport. In addition, a much improved and expanded high-occupancy vehicle (HOV) system would be incorporated along I-93 and I-90 to link downtown Boston at Kneeland Street and the proposed South Station Transportation Center with Logan Airport and points south and west of Boston. Construction activities would result in 13.5 million cubic yards of dredged and excavated material to be disposed of as follows: 1.2 million cubic yards to the Massachusetts Bay Disposal Site, 2.66 million cubic yards to sanitary landfills, 9.3 million cubic yards to Spectacle Island, and 379,000 cubic yards to landfills (utility relocation material). POSITIVE IMPACTS: The Artery/Tunnel Project would have beneficial impacts in central Boston and its immediate surroundings. The capacity of I-93 would increase substantially and, together with the extension of I-90, the freeway would relieve congestion on local streets and on the freeway system. Air quality within the area would improve. Access to downtown Boston and Logan Airport would improve significantly. Economic benefits redounding to the state, the New England County Metropolitan Area, Suffolk County, and the immediate study area would be substantial. Transportation-related energy consumption associated with automobile use would decline by 15 percent in the year 2010. NEGATIVE IMPACTS: Detours and diversions required during construction would increase traffic congestion in some areas. Noise levels would increase at 14 locations by one to four decibels on the A-weighted scale; noise levels would exceed federal standards at some locations. A total of 134 commercial relocations would be required, affecting 4,100 employees. Three historic structures, the House of Bianchi, the Old Colony Railroad bridge, and Railroad Tower A, would be directly affected by the project, and three historic districts would suffer encroachment. Some utility relocation would be required. Approximately 8.4 acres of the Fort Point Channel would be filled, and 3,145 square feet of Boston Harbor bottom would be filled near the General Ship dry dock. Other actions would affect 24 square feet of Lower Charles River bottom and 3,200 square feet of Millers River. Small wetland areas would also be filled, and floodplain encroachment would occur at two saltwater tidal locations and two freshwater nontidal locations. Four publicly owned parks would be affected.

Therefore, application of traditional frequency analysis techniques must be interpreted in a different manner and more sophisticated statistical techniques must be applied to account for this dependence. Decomposition of the annual extremes into two parts, one containing the highly dependent part and the other containing the random part, is one method of dealing with the dependence in the lake elevations. Appropriate statistical analyses can be applied to the separate parts and then the individual results combined to obtain the final frequency relation. This study develops mean monthly lake elevation duration curves to represent the dependent part and wind setup frequency curves for the random part. These parts are then combined by application of the total probability theorem. JF - Technical Papers.

AN - 36409159; 2654 AB - PURPOSE: Construction of a new Trunk Highway (TH) 212 expressway/freeway from the existing four-lane section east of Cologne to the TH 5 /Interstate 494 (I-494) interchange in Eden Prairie, Carver and Hennepin counties, Minnesota is proposed. The 18-mile, four-lane, divided highway would extend across the southwestern portion of the Twin Cities Metropolitan Area. The highway would be constructed as a freeway on new alignment between Eden Prairie and Chaska Township and follow a southwesterly route through the cities of Chanhassen and Chaska. At the western end between Chaska Township and Cologne, the highway would be constructed as a four-lane, divided expressway with at-grade intersections and would follow the existing TH 212 alignment in Dahlgren Township. Five ""build'' and a ""no-build'' alternatives were selected. The five build alternatives are combinations of five corridor segments or options in the eastern portion of the study area and one in the western. The five corridor options would consist of: (1) an alignment north of Lake Riley between the Chaska corporate limit and CSAH 4; (2) south of Lake Riley between Chaska corporate limit and CSAH 4; (3) along TH 5 and west of Mitchell Lake where it would tie into the North Lake Riley alternative (1); (4) along TH 5 and east of the C&NW Railroad, between the CSAH 4 and I-494/TH 5 interchange; and (5) south of TH 5 along the west-southwest diagonal, between the CSAH 4 and I-494 /TH 5 interchange. Estimated costs of construction range from $103 million to $113 million, not including rights-of-way acquisition costs. The project would be phased over a time period to accommodate the availability of funding. Phase I, extending from I-494 to Hennepin County State Aid Highway 4, is programmed for 1994. POSITIVE IMPACTS: The facility would provide for the safe, efficient movement of people and goods between the Twin Cities Metropolitan Area and western Minnesota. Regional transportation needs of the planned population and employment growth in the southwest portion of the metropolitan area would be accommodated. Each build alternative would have an accident rate that is approximately 50 percent lower than that of existing TH 212. NEGATIVE IMPACTS: Rights-of-way requirements would displace 60 to 108 acres of wetland; the majority of wetland displaced would be shallow marsh habitat. Almost 8,000 wildlife habitat units would be lost if 108 acres of wetland were displaced, while 5,000 units would be lost from displacement of 60 acres. From 30 to 41 acres of floodplain would be displaced. Several archaeological and historic sites eligible or potentially eligible for inclusion in the National Register of Historic Places would lie within the rights-of-way. Recreational facilities of the Eden Prairie Middle School could be displaced, and some commercial and residential displacements could occur. Nighttime noise levels would exceed state standards for hundreds of homes along the corridor.

Preparation date: April 26, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED SMITH CREEK PARKWAY AND DOWNTOWN SPUR, NEW HANOVER COUNTY, NORTH CAROLINA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF SEPTEMBER 1980). AN - 36404108; 2658 AB - PURPOSE: This draft supplemental environmental impact statement (EIS) updates and supplements the final EIS of September 1980 for the construction of the Smith Creek Parkway and Downtown Spur within the city of Wilmington and adjacent unincorporated areas of New Hanover County, North Carolina. The 1980 final EIS called for construction of a 5.8-mile, four-lane parkway east of Wilmington that would extend between U.S. 117 near the Northeast Cape Fear River to U.S. 74 east of the city and a 1.9-mile downtown spur that would extend from the parkway along a railroad rights-of-way to the central business district (CBD). The parkway would cross two sets of railroad tracks on grade separation structures and Burnt Mill Creek on a bridge structure. Access to the parkway would be provided at two interchanges. The parkway would have a design speed of 60 miles per hour (mph), while the spur would have a design speed of 45 mph. This supplemental EIS considers the preferred alignment identified in the final EIS and several locally divergent alternative alignments at selected locations. These alternative alignments were developed in response to adjacent developments occurring after 1980 and newly discovered existing conditions. No preferred alternative is forwarded in this supplement. Issues considered in this EIS include the effects of local completion of Interstate 40 (I-40); discovery of two abandoned landfills on the 1980 preferred alignment between McRae Street and Burnt Mill Creek; discovery of hazardous materials on the site of the abandoned Caro-Knit Textile Plant in the northwest quadrant of the intersection of 23rd Street and Smith Creek Boulevard; additional wetland involvement; alteration in the alignment of the north terminus of the Downtown Spur to include a new bridge crossing of Smith Creek; development of DEG Studios (now N.C. Film Studios) in the southwest quadrant of the intersection of 23rd Street and Smith Creek Boulevard; construction of the Dorothy B. Johnson Elementary School east of McRae Street; expansion of the Corning Glassworks Plant east of College Road (NC 132) to include the production of fiber optics cable; expansion of residential development east of Kerr Avenue, particularly within the Crestwood Estates Subdivision east of College Road; and growth of Port Wilmington and the increasing importance of transportation access to the port facility. The estimated costs of the project range from $80 million to $90 million. POSITIVE IMPACTS: Parkway and spur construction would implement a portion of the Wilmington Thoroughfare Plan under consideration since 1972. East-west access between downtown Wilmington and the rapidly developing eastern suburbs and coastal resort areas in adjacent New Hanover County would be improved substantially. The segment of I-40 extending to the Wilmington area would be complemented. NEGATIVE IMPACTS: Rights-of-way requirements would displace 180 to 200 acres of land not committed to other uses. Other land to be displaced would include 43 acres of upland habitat, 34 acres of wetland habitat, 27 to 39 acres of abandoned railroad rights-of-way, 35 to 41 acres of residential or commercial property, 11 to 12 acres of industrial property, 13 acres of city or county property, and 20 acres of miscellaneous vacant urban land. Certain aesthetic, cultural, and social values within the corridor would be affected. Approximately 1.8 million cubic yards of embankment material as well as substantial quantities of structural steel, asphalt, concrete, and other construction materials would be committed to the project.

AN - 36402915; 2594 AB - PURPOSE: Construction of a sand transfer system to support the Canaveral Harbor shoreline restoration and nourishment project along a two-mile reach of shoreline south of Canaveral Harbor in Brevard County, Florida is proposed. This final supplement to the final environmental impact statement of May 1972 on the overall beach erosion control project for the Cape Canaveral area of Brevard County assesses the environmental impacts associated with renourishment of a 2-mile reach of ocean shoreline south of the entrance channel and implementation of the authorized sand transfer plant as described in the General Design Memorandum for the Canaveral Harbor Sand Bypass System. The transfer system would include five jet pumps, a pipe catwalk, an operations building, booster stations, and connecting pipelines and valves as required. The jet pumps would be located approximately 150 feet north of the north jetty and would be spaced at intervals of 60 feet between mean high water and 6 feet below mean high water in a line parallel to the north jetty. The transfer system would move 106,000 cubic yards of material accreting north of the Canaveral Harbor entrance channel's north jetty to the beach south of the south jetty each year. The project would also involve extending the south jetty for a distance of 500 feet, with sand tightening of the entire structure to reduce erosion and requirements for channel maintenance dredging by intercepting northward movement of materials. A program to prevent smothering of sea turtle hatchlings would be implemented. POSITIVE IMPACTS: In general, the project would contribute to the replacement of erosional losses to the Cape Canaveral beachfront and the reduction of excessive shoaling in the Canaveral Harbor entrance channel. Sea turtle nesting habitat would be preserved. NEGATIVE IMPACTS: Public use of the beach would be disrupted during nourishment operations, and free-swimming marine organisms near the shoreline would suffer from periodic turbidity. Benthos in the offshore dredging area would be destroyed, as would benthos covered by nourishment materials.

Preparation date: April 10, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOCAL FLOOD PROTECTION, PETERSBURG, GRANT COUNTY, WEST VIRGINIA. AN - 36402869; 2599 AB - PURPOSE: Implementation of a flood control plan for North Petersburg, South Petersburg, and the Grant County Airport Industrial Park, West Virginia is proposed. The entire study area lies within eastern Grant County. The incorporated area within the city of Petersburg covers approximately 0.7 square mile and straddles the South Branch Potomac River. The recommended plan would include 19,370 feet of earthen levee, 920 feet of floodwall, 35,430 cubic yards of channel excavation near the Main Street bridge, bridge replacement /modification, environmental mitigation, and appurtenant project features such as ramps, closures, riprap, relocations, and ponding areas for local drainage. Environmental mitigation features associated with the plan would include off-project land acquisition and planting of high-quality vegetation; a total of 25 acres of fruiting trees and shrubs would be planted, providing 100 percent mitigation for impact to categories 3 and 4 habitat. To address the short flood warning time for this section of the South Branch, a flood warning system, built on the existing IFLOWS system, would be implemented. The estimated first cost of the plan, including future price escalation through project completion, is $20.28 million. Average annual costs are estimated at $1.8 million, and the benefit-cost ratio is estimated at 1.24. Significant cost savings could be realized for the recommended plan if detailed engineering analyses of the bridge reveal that replacement at the 100-year design flood level is not required. The preconstruction engineering and design phase would be implemented over 30 months. Construction of the project would require 24 to 30 months. POSITIVE IMPACTS: Project implementation would provide for protection against the 100-year flood, preventing losses to property and health and safety hazards within the flood control area. The project would also provide annual flood control and other benefits worth $2.28 million, for a net annual benefit of $446,000. Provision of flood protection would probably attract additional business to the Petersburg area. NEGATIVE IMPACTS: A total of 47.5 units of upland habitat would be destroyed by the project. Levee construction would permanently displace approximately 26 acres of land, consisting primarily of abandoned farmland, cultivated fields, pastures, and urban land. Project structures would block the view of the river from some locations. Houses and mobile homes along the new levee would be displaced, and two potentially significant prehistoric cultural sites could be affected by levee construction.

Preparation date: April 10, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STILLWATER-HOULTON TRANSPORTATION SYSTEM, MN-TRUNK-HIGHWAY-36 AND WI-TRUNK-HIGHWAY-64 IMPROVEMENTS: MN-TRUNK-HIGHWAY-36 AND WASHINGTON COUNTY STATE-AID-HIGHWAY-15 TO WI-TRUNK-HIGHWAY-64 NEAR THE SAINT CROIX RIVER BRIDGE, WASHINGTON COUNTY, MINNESOTA AND SAINT CROIX COUNTY, WISCONSIN. AN - 36400434; 2591 AB - PURPOSE: The reconstruction of Trunk Highway (TH) 36 in Washington County, Minnesota, is proposed. The project would include functional replacement of the existing drawbridge over the Saint Croix River and reconstruction of approach highways leading to the bridge in Saint Croix County, Wisconsin. The study area termini are the vicinity of County Road 15 in Minnesota and a point on STH 64 approximately 2.5 miles east of the state line in Wisconsin. The possibility of improving existing TH 36 from Houlton to New Richmond, 15 miles to the east, is currently under study. This represents a separate study based on transportation needs independent of the river crossing analysis. Three basic build alternatives and a no build alternative are under consideration. The build alternatives include the North Corridor, which would bypass the cities of Stillwater, Minnesota and Houlton, Wisconsin to the north; the Central Corridor, which would use existing approach roadways in Minnesota and Wisconsin while bypassing the Stillwater central business district; and the South Corridor, which would bypass the cities of Stillwater, Minnesota and Houlton, Wisconsin to the south. The North Corridor Build Alternative contains two potential river crossing construction options on different alignments, consisting of a 2,500-foot-long bridge over the Saint Croix River and an 8,200-foot-long tunnel under the Saint Croix River. The Central Corridor Build Alternative would consist of a single river crossing construction option, with four potential design variations. The South Corridor Build Alternative would involve three potential bridge crossing alignments, with eight different design variations; an additional alignment would consist of an 8,800-foot-long tunnel under the Saint Croix River. POSITIVE IMPACTS: In addition to major transportation service, safety, and congestion improvements that would occur with the construction of any of the alternatives, there would be several social, economic, and environmental benefits. A hindrance to resolution of a significant problem in planning the nature of the future transportation network serving 11 study area communities would be removed. Reduction in air pollutant emissions, energy use, and traffic-generated noise, as well as improved water quality would also result. NEGATIVE IMPACTS: The rights-of-way requirements would result in the displacement of 30 to 61 households, one or two small businesses, and a substantial amount of agricultural land. The construction of a new bridge or tunnel in the St. Croix River Valley would alter a component of the National Wild and Scenic Rivers System. The North Corridor could pass over Mile Long Island, a popular recreational site on the Lower Saint Croix National Scenic Riverway, and a northern tunnel could have serious impacts on the lower portions of Brown's Creek, which flows through a scenic valley north of Stillwater. The project could also affect the habitat of the Higgins' eye pearly mussel, a species of clam found in the Saint Croix River that is a federally listed endangered species. Historic and archaeological sites located in Stillwater and Houlton, including the existing drawbridge, which was recently listed on the National Register of Historic Places, could be adversely affected.

AN - 36402223; 2547 AB - PURPOSE: Implementation of improvements at Naval Base Pearl Harbor on Oahu, Hawaii is proposed. Developments would include improvement of access to Ford Island, further development of Ford Island, and construction of various operational personnel support facilities on the island, the Naval Shipyard, and the Naval Station to support relocation of a battleship and two cruisers. Specific actions would include the preferred alternative, which involves construction of a floating bridge to Ford Island; construction of a fixed bridge, sunken tube tunnel, and expanded water system; development of a mainside terminal facility at Richardson Recreation Center from Halawa Landing; development of a Ford Island terminal facility at Saratoga Boulevard; and sale of some property to the state of Alaska to provide funding for project improvements. Facilities developed under the project would include family housing, troop housing, personnel support facilities, and operational facilities. Relocation of the battleship and cruisers would require improvement of electrical and fender systems, development of a transient personnel unit, club facility expansion, and development of a fleet shoreside support center. Other support projects include the development of a material storage facility and an applied instruction building. This project is part of the general base realignment and closure activities affecting the entire United States. POSITIVE IMPACTS: Improvements on Ford Island would allow use of the full potential of the island site. The density of development on the island would be more congruent with mainland development density. The cost-effectiveness of Naval operations at Pearl Harbor would be improved significantly. NEGATIVE IMPACTS: Dredging, filling, and pile driving activities would result in short-term increases in turbidity and temporary losses of marine benthos. Access to a portion of the harbor and to recreational and commercial fishing boats would be hindered temporarily during construction activities. Utility line relocations would be necessary. Over the long term, surface water circulation patterns would be altered somewhat due to the existence of the floating bridge, which would also constitute a navigational restriction and displace some recreational boat moorings. Subsurface archaeological deposits at terminal locations could be impacted. The visual character associated with a historically significant site, Pearl Harbor, would be altered, and some historical structures would be displaced. Existing and planned family housing facilities at Ford Island would be impacted in terms of neighborhood character, views, traffic noise, and loss of space for additional construction. Additional traffic congestion during peak hours would result on Kamehameha Highway. The Ford Island runway would be displaced. The present capacity of the Navy sewage treatment plant would be exceeded, and water supply and electrical demands would increase significantly. Increases in electrical demands would result in air quality impacts. Bird habitat would be displaced. LEGAL MANDATES: Base Closure and Realignment Act of 1988 (P.L. 100-526).

AN - 36400230; 2597 AB - PURPOSE: Designation of an ocean dredged material disposal site in the Pacific Ocean off the mouth of the Chetco River in Oregon is proposed. The proposed site, which has served as an interim site since 1977, is located approximately one mile south of the Chetco River entrance. The area in which the site is located has been used by the Portland Army Corp of Engineers as a disposal area since 1963. The site dimensions are 1,800 feet by 1,800 feet, and the site would have an average depth of 70 feet. The site occupies approximately 74 acres (0.08 square nautical mile). Exact site boundaries would be 42 degrees (d), 1 minute (m), 56 seconds (s) north latitude (N) by 124 d, 16 m, 33 s west longitude (W); 42 d, 1 m, 56 s N by 124 d, 16 m, 9 s W; 42 d, 1 m, 38 s N by 124 d, 16 m, 9 s W; and 42 d, 1 m, 38 s N by 124 d, 16 m, 33 s W. The channel from which the material is to be dredged includes a 14-foot-deep, 120-foot-wide entrance channel; a 14-foot-deep, 250-foot-wide, 650-foot long barge turning basin; and a 100-foot-wide, 12-foot-deep small-boat access channel. POSITIVE IMPACTS: By providing a permanent disposal option for material dredged from navigation channels in the Chetco River, site designation would support economic uses of the river channels. Federal channels in the Chetco River must be maintained to decrease waiting times for vessels crossing the bar, provide adequate channel dimensions for tugs, barges, and commercial fishing vessels, provide mooring facilities for small boats, permit barge and small-boat traffic upstream to river mile 0.2, and provide a harbor of refuge. The site would provide the most suitable means for disposing of dredged material in terms of environmental and navigational requirements. NEGATIVE IMPACTS: Dumping of material at the proposed site would result in the temporary alteration of site topography via mounding, smothering of benthos at the site, and temporary disturbance of the water column due to turbidity and chemical releases, as well as in the reduction of dissolved oxygen levels. Habitat at the site could be altered. LEGAL MANDATES: River and Harbor Act of 1945 (P.L. 79-14) and Marine Protection, Research, and Sanctuaries Act of 1972 (33 U.S.C. 1401 et seq.).

Basic purposes of the guide are to provide detailed information on evaluation of oceanographic parameters, collection of field samples, and performance of laboratory analyses. Another objective is to clarify the role of the monitoring program that may be instituted at each site pursuant to final site designation and to relate its content to the original site survey. Because the scientific content of the surveys is, in part, related to physical characteristics of the sites, such as size, depth of water, distance from shore, these characteristics as they pertain to sites in the various Corps Districts are discussed in detail. There is also a discussion of the common features of the oceanography of the US continental shelf because over 80% of existing sites are located on the shelf. A substantial portion of the guide is devoted to the selection of variables to be measured in the field and the rationale for placement of sampling stations, as well as gear appropriate to various conditions. Detailed guidance is given on the preferred methods of sample analysis, including biological, physical, chemical, and geological methodologies. Suggestions are given for effective presentation of the field and laboratory data generated during the site survey. Because site designation does not, in itself, include the disposal of dredged material, the methodologies are, so far as possible, compatible with those used for the evaluation of material proposed for disposal. Although site designation, evaluation of material for disposal, and monitoring are separate activities, they are part of a continuum and should share common techniques so as to be cost-effective and of maximum technical validity.

AN - 36391755; 2590 AB - PURPOSE: Improvement or rerouting of State Route (SR) 509 and connecting arterials in the Port of Tacoma industrial area, from Interstate 705 (I-705) to Marine View Drive, in Pierce County, Washington is proposed. Two action alternatives and a no action alternative are under consideration. Alternative 1 is the no action alternative. Alternative 2 would maintain East 11th Street from Marine View Drive to Pacific Avenue as the east-west SR 509 corridor. The Blair Bridge would be replaced with a new four-lane lift bridge in 1994, after the widening of Marine View Drive to three lanes from East 11th Street to Taylor Way to accommodate detour traffic. By the year 2000, the East 11th Street viaduct would be extended west of Milwaukee Way and east of Thorne Road, and the Hylebos Bridge would be replaced with a new four-lane bascule bridge. Alternative 3 would provide a new east-west corridor around the port waterways by way of Marine View Drive from East 11th Street to Taylor Way, continuing along East-West Road and extending west to I-705 at its 21st Street interchange. This corridor would become SR 509. By 1995, a four-lane freeway viaduct would be built from I-705 to Milwaukee Way. East-West Road would be expanded and improved to form a two-lane westbound surface parkway from Taylor Way to Milwaukee Way, and a parallel two-lane eastbound parkway would be constructed approximately 250 feet to the south. Marine View Drive would be expanded to five lanes from Taylor Way to the future Norpoint Way Connector, and three lanes from the future Norpoint Way Connector to East 11th Street. In conjunction with these improvements, the Blair Bridge would be permanently removed. By the year 2000, a four-lane freeway would be constructed from Milwaukee Way to Taylor Way between the two new surface parkways, with grade separations at all cross streets, and a four-lane Norpoint Way Connector would be constructed from a point on Marine View Drive 3,900 feet south of the existing Norpoint Way intersection to a point on Norpoint Way 4,000 feet northeast of the intersection. Estimated costs of alternatives 2 and 3 are $95.3 million and $165.4 million, respectively; both estimates are in 1989 dollars. POSITIVE IMPACTS: Proposed highway improvements would accommodate increasing development and traffic in the industrial area, reduce bridge and rail delays along East 11th Street, and allow access to the Blair Waterway, which is currently blocked due to design deficiencies associated with the Blair Bridge. Depending on the alternative chosen, construction activities would create 1,000 to 2,000 jobs. Port-related development assisted by the project would create 11,000 direct and 20,000 indirect jobs under Alternative 2 and 17,000 direct and 31,000 indirect jobs under Alternative 3. In general, either alternative would accelerate port development, but Alternative 3 would do so more than Alternative 2. NEGATIVE IMPACTS: Alternative 2 would displace 0.4 acre of wetland. Alternative 3 would displace or disturb 2.6 acres of wetland and could require rights-of-way acquisition affecting six residences and four businesses. Either alternative could significantly increase the ambient levels of inhalable airborne particulate matter. Either alternative would result in slight exceedances of federal noise standards. Alternative 2 would cause serious delays in emergency response times during construction, while Alternative 3 would result in less serious delays. Either alternative could result in the failure of 11 businesses along East 11th Street that depend on through traffic.

AN - 36404006; 2598 AB - PURPOSE: Completion of a flood protection project along the floodplain of Wheeling Creek in Wheeling, West Virginia is proposed. The 191,180-acre project area would include land in Greene and Washington counties, Pennsylvania, and Ohio and Marshall counties, West Virginia. This final supplement to the final environmental impact statement (EIS) of April 1982 describes the existing and projected watershed problems and contains the Wheeling Creek Watershed Work Plan Supplement No. 5, which incorporates means of addressing these problems. A large flood in November of 1985, causing approximately $20.9 million in flood damages, caused residents to question the deletion of a previously proposed dam from planned watershed project measures. This supplemental work plan and supplemental EIS recommend construction of a floodwater retarding structure on Dunkard Fork near its confluence with Wheeling Creek in Marshall County, West Virginia to provide additional flood damage reduction in the city of Wheeling, West Virginia. The dam would be a single-purpose flood control structure located approximately 14 miles upstream of Wheeling. The embankment, to be located approximately 0.4 mile upstream of the confluence of Dunkard and Enlow forks, would extend 1,060 feet and have a height of 83.5 feet. The embankment would consist of compacted earth and rock fill. The drainage area of the dam would extend over 77.1 square miles. The dam would provide temporary storage for 8,476 acre-feet of floodwater, which is the equivalent of approximately 2.1 inches of runoff over the entire drainage area. The dam would trap 601 acre-feet of sediment over the 100-year design period. Initially, the sediment pool would fill with water, creating a 27-acre lake; recreational facilities to enhance use of the lake as a fishing resource would be provided. During flood flows, floodwater would be stored upstream of the embankment, creating a temporary lake with a maximum surface of 495 acres at the top of the dam elevation. Wildlife habitat mitigation measures would include provisions for an island within the lake, placement of riprap along the shoreline and rock piles and boulders within the lake, wetland development on 3.0 acres in the spoil disposal area, and acquisition of conservation easements. The estimated cost of the project is $24.4 million. POSITIVE IMPACTS: Flood damage affecting Wheeling would decline significantly, as well as all flood damage affecting communities along the floodplain downstream from the dam to the backwaters of the Ohio River. Approximately $1.6 million in annual benefits would result from the project. Fishing developments and mitigation measures would add to the recreational value of the watershed. Average annual flood damages would decline. Sediment storage behind the dam would improve downstream water quality. NEGATIVE IMPACTS: Creation of the lake would displace 1.1 miles of warm-water stream fishery habitat, as well as 103 acres of terrestrial wildlife habitat. The sediment pool would displace 18 acres of bottomland, most of which is cropland. Borrow excavations would alter 10 acres of cropland and 21 acres of forests, while the disposal area would affect 12 acres of forest. The flood pool would periodically inundate 298 acres of wildlife habitat, 106 acres of prime farmland, and 3.9 miles of streams. The surface water temperature of the impounded water would increase five degrees Fahrenheit above the present stream temperatures during late summer. Four families, operating farming enterprises, would require relocation.

These surveys have shown that both English sole and Dungeness crab rely heavily in these estuaries as nursery areas, although the pattern of utilization differs substantially. Juvenile migration patterns can show substantial interannual variability and can only be delineated by concurrent surveys in both coastal and estuarine areas, conducted over a period of several years. English sole eggs and Dungeness crab larvae are released in coastal waters. Larvae of both species transform to the benthic stage in both coastal and estuarine areas, but most English sole eventually migrate into the estuaries during the first year of life, even if initial settlement is along the open coast. By the time English sole have attained a length of 55 mm (TL), most of them are found in estuaries. English sole begin emigrating from the estuaries at about 75 mm, and few remain there during the second year of life. Growth is substantially faster in estuaries where 0+ crab reach a mean size of about 40 mm carapace width (CW) by September, with those off the coast are only about 14 mm CW. Juveniles remain in the areas of settlement over their first winter but, in contrast to the English sole, most coastal 1+ crab immigrate to estuaries to join siblings that settled there the previous year. By September of the second year, crab at about 100 mm CW emigrate to the open coast where they reach maturity. Advantages to juvenile stages that reside in estuaries include accelerated growth at higher temperatures and potentially greater food supplies than found nearshore along the coast.

NORTH OF HUMBOLDT/DEL NORTE COUNTY LINE, REDWOOD NATIONAL PARK BYPASS PROJECT, INCLUDING GRAVEL EXTRACTION AND PROCESSING NEAR KLAMATH GLEN, DEL NORTE COUNTY, CALIFORNIA (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF FEBRUARY 1984). AN - 36404934; 2586 AB - PURPOSE: Construction of 12 miles of four-lane highway for the U.S. Redwood National Park Bypass Project in Humboldt and Del Norte counties, California is proposed. The bypass would begin at a point 0.5 mile south of the Mae Creek bridge, follow the north side of Mae Creek drainage, and skirt the eastern edge of the state park to intersect with existing U.S. 101 approximately 0.5 mile north of the Humboldt /Del Norte county line. The initial 4.5 miles of road would climb approximately 1,400 feet at a sustained grade of 5 to 7 percent. From its high point on the east side of the state park, the road would begin a descent at a grade of 4 to 6 percent for approximately 1.5 miles, followed by a slight upgrade for approximately 1.0 mile. The downgrade on the final 4.6 miles would be approximately 6 percent. Large embankments and long cut areas would be required. This final supplement to the final environmental impact statement of February 1984 on the highway construction project evaluates alternative sources of gravel for the manufacture of aggregate needed to complete the third stage of the bypass project, which would begin in the spring of 1990 and involve placing the base and paving and installing a drainage system. Extraction and processing of approximately 500,000 cubic yards of gravel would be required to produce material for the subbase, base, and asphalt-treated base, and asphalt concrete needed to complete the bypass project. Gravel processing would include crushing, sorting, washing, and manufacturing of the final product. Available gravel source sites include the Blake Bar property located on the Klamath River just south of Klamath Glen; an active two-mile reach of Turwar Creek just north of Klamath Glen; and the Tracy property located adjacent to the downstream end of the Blake Bar property. Alternatives under consideration could involve the use of one or various combinations of these sites. The currently preferred alternative, identified for the first time in this final supplement to the final environmental impact statement, would involve the combined use of the Blake and Tracy Bar sites. A total of 350,000 cubic yards of material would be extracted from the two sites, with the remaining material taken from commercial sources. A one-percent slope toward the river would be retained to minimize trapping of fish, and a buffer strip would be retained along the Klamath River. The buffer strip would be breached each Fall to prevent stranding fish. This alternative was selected when it was discovered that extraction from Turwar Creek could exacerbate ongoing undermining of the Klamath Glen flood control levee. POSITIVE IMPACTS: The bypass would remove through traffic from the existing portion of U.S. 101 within the park and improve commercial and long-distance travel on the only north-south highway in the north coast region of the state. Congestion caused by slow-moving tourists passing along the segment of highway that traverses the park would be eliminated by separating through traffic from tourist traffic. Extraction would enlarge channel capacity, thereby reducing flood risk. NEGATIVE IMPACTS: Required earthwork for cuts and fills would be extensive. A temporary decrease in air quality due to dust from extracting and processing operations is expected. Odors may result from asphalt processing. Some disturbance of wildlife habitat may occur.

Preparation date: February 28, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DIAMOND FORK POWER SYSTEM, BONNEVILLE UNIT, CENTRAL UTAH PROJECT (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1984). AN - 36399610; 2482 AB - PURPOSE: Development of a power system, to be known as the Diamond Fork Power System, is proposed as a component of interrelated systems in the Central Utah Project's Bonneville Unit. The Diamond Fork System, in north-central Utah, would effect a transbasin diversion of water from the Uinta Basin of the Upper Colorado River Basin to the Bonneville Basin of the Great Basin. Most of the system facilities would lie within Utah County, but a small portion at the upper end of the project's structures would be in Wasatch County. The system would be constructed in the Diamond Fork and Sixth Water drainages in the Uinta National Forest of the Wasatch Mountain range. Sixth Water is a tributary of Diamond Fork, which is a tributary of the Spanish Fork River. The transbasin diversion would provide water for the Municipal and Industrial System of the Bonneville Unit and for supplemental irrigation service in the Spanish Fork area of south Utah County. Water would also be provided for the Irrigation and Drainage System of the Bonneville Unit. The transbasin diversion would descend from the enlarged Strawberry Reservoir in the Uinta Basin to the confluence of Diamond Fork and the Spanish Fork River in the Bonneville Basin through a system of tunnels, pipelines, and a powerplant. The system would facilitate an annual average transbasin diversion of 101,900 acre-feet of Bonneville Unit water and 61,500 acre-feet of Strawberry Valley Project water from the Uinta Basin to the Bonneville Basin. This supplement to the final environmental impact statement (FEIS) of October 1984 discusses the proposed reduction in the size of the power system design. Changes in market conditions make the plan submitted in the FEIS no longer practical. The recommended plan presented in this supplement would provide 56.5 megawatts (MW) of installed generating capacity compared to the 166.2-MW system described in the FEIS. Approximately 10.5 MW would be needed to meet the requirements of the Bonneville Unit, depending on the alternative selected. Facilities added to the recommended plan since the FEIS include the Sixth Water Aqueduct and Last Chance Powerplant. Facilities deleted since the FEIS include the Syar Powerplant, Corona Aqueduct, Sixth Water Powerplant and Dam, and Dyne Aqueduct and Powerplant. POSITIVE IMPACTS: Development of water and energy sources through the plan would fulfill the project objectives of supplying immediate and projected needs for the rapidly growing population along the Wasatch Front. Some project energy would be used to pump water for the Central Utah Project, while the remainder would be marketed for commercial use throughout the Colorado River Storage Project marketing area. In addition to providing water and power, the system would open up recreational and fishing opportunities in the area. NEGATIVE IMPACTS: Project development would destroy 438 acres of vegetation permanently and 132 acres temporarily. Maximum stream flows in Sixth Water Creek and Diamond Fork between Last Chance Powerplant and Monks Hollow Reservoir would be moderately to significantly less than under the 1984 FEIS plan. Water temperature stratification within the Strawberry Reservoir would be altered. Habitat, including that of endangered species, would be displaced, and grazing capacity in the area would decline; the cost to grazing permittees would increase.

Preparation date: February 22, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - U.S. ROUTE 71, I-44 TO ARKANSAS STATE LINE, JASPER, NEWTON, AND MACDONALD COUNTIES, MISSOURI: JOB NO. 7-P-71-427. AN - 36409317; 2517 AB - PURPOSE: Construction of a divided, dual-lane, controlled-access highway between Interstate 44 (I-44) and the Arkansas state line in Jasper, Newton, and McDonald counties, Missouri is proposed. The project would begin in southern Jasper County and cross both Newton and McDonald counties before reaching the Arkansas state line. The 41- to 45-mile highway would have a 24-foot, 2-lane pavement in each direction with 10-foot outside shoulders and a 60-foot median. Access to the facility would be available only by interchanges. Improvements to existing Route 71 between Joplin and Tipton Ford or Joplin and Neosho would be required and are included in this project. Two primary build alternatives are under consideration. The combination of segments of the two primary alternatives at two separate locations comprise third and fourth alternatives. A No Build alternative was also considered. Alternative 1 would begin at I-44, approximately three miles east of the city of Joplin, then proceed south along the existing Route 71 corridor to the Arkansas state line. Alternative 2 would begin at the I-44/U.S. Route 71 Alternate (71A) interchange south of the city of Carthage, proceed south along the Route 71A corridor to a point east of Neosho where existing U.S. 60/71A curves west, and continue south on a relocated route to the Arkansas state line. Alternative 3 would connect Alternative 2 to Alternative 1 via Route 60/71A south of the city of Neosho. Alternative 4 would connect Alternative 2 to Alternative 1 via relocation just south of Missouri Route D (Newton County) to a point near Kelly Springs north of the city of Anderson. Estimated costs of alternatives 1, 2, 3, and 4 are $215.9 million, $259.6 million, $239.0 million, and $244.3 million, respectively. Alternative 1 is the preferred alternative. POSITIVE IMPACTS: The freeway would become part of a north-south, multistate system from Kansas City, Missouri to Shreveport, Louisiana. Capacity problems affecting the existing facility would be relieved. Existing and expected traffic levels would be accommodated. Driving safety would be improved. Regional development and its economic competition are expected to improve with the construction of this highway through the attraction of manufacturers and industries, increased employment opportunities, increased retail sales, increased tax revenues, and better access to recreational facilities located in the region. NEGATIVE IMPACTS: Development of 2,005 acres of rights-of-way would result in the displacement of 100 families, 328 persons, 96 residential units, and 26 commercial units. Five nonprofit organizations/schools would also be displaced. Other land uses affected would include 37.5 acres of wetlands, 14,400 linear fee of floodplains, and known cultural resource sites.

AN - 36409281; 2515 AB - PURPOSE: Widening of a 12.1-mile segment of existing US 27 and US 68 from Rogers Road in Lexington to Parkway Drive in Paris, in Fayette and Bourbon counties, Kentucky is proposed. Most of the proposed project (approximately 10.8 miles) would be improved as a rural facility; an approximately 0.6-mile segment leading into Lexington and a 0.7-mile segment leading into Paris would be improved as urban facilities. The existing facility, known locally as the Lexington-Paris Road or Paris Pike, is a two-lane rural arterial with left-turn lanes at major intersections. Lanes are generally 11 feet wide and shoulders are not paved. The proposed improvements would involve widening the existing two-lane facility to function primarily as a four-lane divided rural principal arterial, with short terminal sections leading into Paris and Lexington. Bridges at Elkhorn Creek and Houston Creek would be reconstructed as four-lane facilities as part of the proposed actions. Five build alternatives are under consideration. Alternative A would provide a high-type rural arterial facility with partial control of access; a 40-foot depressed grass median would be included except at the project terminals. Some driveways would be relocated and frontage roads would be used in several locations. Alternative B would use a minimum-width arterial cross-section, which would maintain a 14-foot flush median for the entire length of the project. The profile grade for Alternative B, as well as for alternatives C, D, and E, would follow the existing terrain more closely than Alternative A, thus reducing earthwork and rights-of-way requirements. Alternative C would use a 22-foot grassed median, except in urban areas, where an urban cross-section would be used to minimize impacts on several properties. Alternative D would consist of the minimum desirable width rural cross-section, with a 40-foot depressed grassed median. In urban areas at project termini, urban cross-sections would be used. Alternative E would minimize impacts on visible cultural features in the corridor by minimizing the project rights-of-way width. This document is a draft supplement to the final environmental impact statement of September 1972. POSITIVE IMPACTS: The importance of Paris Pike in the area's regional transportation system would be maintained and supported. Current capacity shortcomings would be alleviated, and inadequate road geometrics and design features would be corrected. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of up to seven residences. Properties within the Paris Pike Historic District would be affected; less than 0.1 acre of wetlands would be lost. Floodplains associated with the Elkhorn Creek and Houston Creek drainages would be crossed, but no significant risk of increased flood hazards would occur.

Preparation date: February 21, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ROCK CREEK/MUDDY CREEK RESERVOIR, ROUTT AND GRAND COUNTIES, COLORADO. AN - 36408315; 2532 AB - PURPOSE: Construction of a water storage reservoir, located in Grand County in western Colorado, is proposed. During review of the draft environmental impact statement, two projects were considered, namely, the Rock Creek Reservoir in the Routt National Forest and Muddy Creek Reservoir in the Kremmling Resource Area. The Muddy Creek Reservoir has been chosen as the preferred project, although further studies of the Rock Creek site are recommended. The Muddy Creek project site would be located just west of Wolford Mountain (five miles north of Kremmling, Colorado). The Muddy Creek Dam would be a zoned earthfill dam, with a dam crest located 120 feet above the present streambed. The dam would contain approximately 997,200 cubic yards of fill; the majority of this material would be obtained from borrow areas immediately upstream and downstream of the damsite, resulting in a haul distance of less than one mile. Approximately 42,800 cubic yards of riprap material would have to be hauled 40 miles from a quarry to the east of the project site. An additional 76,700 cubic yards of materials for filters, drains, and concrete aggregate could be supplied by a firm in Kremmling. It would create a 60,000-acre-foot capacity reservoir, which would include 4,000 acre-feet of conservation storage and 6,000 acre-feet of sediment storage. Annual water yield would amount to 23,000 acre-feet. The reservoir would have a surface area of 1,447 acres and extend 5.5 miles up Muddy Creek. The dam would feature a multiple outlet. During construction, Muddy Creek would be diverted through a conduit located on the right side of the streambed. Relocation of a portion of U.S. Highway 40 and two electric transmission lines would be required. A campground and picnic area would be developed in association with the reservoir. POSITIVE IMPACTS: The Muddy Creek Reservoir would primarily be a source of augmentation water. Reservoir operations would fulfill primary demands under the Metro Denver Lease, including provision of water for the Middle Park Water Conservancy District. Releases would be made in exchange for water stored in the Green Mountain Reservoir. Beneficial impacts would include increased recreational use of the reservoirs and associated campgrounds, reservoir fish habitat, and the economic benefits of the recreational use. Releases from the reservoir could also enhance the cold water trout fishery in the tailwater of the dam. Construction activities would result in significant increases in area employment rolls. NEGATIVE IMPACTS: The dam and reservoir would displace 822 acres of farmlands. The potential for fogging in the vicinity of the project site would increase. Endangered fish species would be impacted. The area would undergo a long-term social change due to the reservoir and associated development, and would impact wetlands, a candidate federal rare plant, big game habitat (elk and deer), and visual resources.

AN - 36391955; 2526 AB - PURPOSE: Issuance of a permit to discharge fill materials into the Big Tujunga Wash in the Sunland-Tujunga District Plan area of the city of Los Angeles, California is proposed in association with the development of the Los Angeles International Golf Club. The project site is located at 9401 Foothill Boulevard in the Big Tujunga Wash, which lies in the Tujunga Valley, just south of the northwestern portion of the San Gabriel Mountains. The San Gabriel Mountains are a transverse range with many drainages on their southwestern flank that contribute to flow through the Hansen Dam Park Flood Control Basin into the Los Angeles River. The golf course would cover approximately 355 acres, including a private 18-hole course consisting of 82 acres of turfed golf course area, 54 acres of revegetated gallery mounds, 6 acres of water features, and 18 acres consisting of club house, maintenance, security, and parking facilities. Approximately 160 acres would be developed to accommodate a tournament-level golf course; the remaining 195 acres would be retained as open space, including a 65-acre preserve for slender-horned spineflower and 7.6 acres of riparian revegetation. The golf course is proposed as a private facility for 500 corporate memberships and would not be open to the public. The course would be open for play six days a week (closed on Mondays for maintenance work). The driving range and course would not be lighted and would generally be in operation between sunrise and sunset. The fill material would provide the level of flood protection required by the city of Los Angeles and prevent encroachment into two populations of slender-horned spineflower, a federally listed endangered plant found in the study area. Construction of the proposed project would require approximately 2.6 million cubic yards of fill material, of which some 2.0 million cubic yards would be imported from the Hansen Dam Flood Control Basin; the remainder would be excavated from drainage channels. POSITIVE IMPACTS: The golf course would meet the criteria of the Professional Golfer's Association tournament-level play, allowing the permit applicant to accommodate the Los Angeles Open, which has outgrown its current facility. Funds generated by the event would continue to support the Los Angeles Jay Cee-sponsored charitable events, such as the Special Olympics. In addition, the expanded facilities would meet an existing demand for golfing facilities in the city of Los Angeles, reduce flood hazard levels in the vicinity, and provide for the preservation of the above-mentioned endangered species, along with the associated seed bank and 65 acres of alluvial scrub resources. NEGATIVE IMPACTS: Approximately 315,000 cubic yards of fill material would be discharged into U.S. waters. A total of 143 acres of alluvial scrub habitat would be displaced. Traffic generated by the expanded golf course would contribute to air pollution in an area that already violates federal air quality standards.

Preparation date: February 20, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - U.S. HIGHWAY 91, BRIGHAM CITY TO WELLSVILLE, BOX ELDER AND CACHE COUNTIES, UTAH. AN - 36400273; 2522 AB - PURPOSE: Improvement of approximately 13 miles of State Route (S.R.) 91 from Brigham City to Wellsville in Box Elder and Cache Counties, Utah is proposed. This highway segment is also designated as U.S. 89. Four build alternatives and a No Action alternative are under consideration. All build alternatives would provide a roadway with four 12-foot lanes, a 6-foot to 14-foot median, and 10-foot outside shoulders. Alternative 1 would require total reconstruction of S.R. 91 within the corridor under consideration from MP 3.9 to MP 16.95. The existing horizontal alignment would be followed relatively closely for the entire length. In Box Elder Canyon, cut slopes ranging up to 132 feet in height would be required. Retaining walls ranging from 10 to 25 feet in height would be constructed to reduce impacts to Box Elder Creek. Extensive rock blasting would be required through much of the canyon. The roadway through Wellsville Canyon would be raised 15 to 25 feet with fill material to obtain sufficient width for the wider roadway while avoiding extensive cutting on high, unstable slopes. The bridge over Box Elder Creek at the west end of the project would be modified or replaced to provide adequate shoulders. Culvert replacement would be required at all six stream crossings to accommodate the increased width of the proposed roadway and to provide passage for fish. Approximately 510 feet of Box Elder Creek would be relocated. Alternative 2 would be similar to Alternative 1, with the exception that the roadway surface through Box Elder Canyon would be shifted approximately 25 feet to the north to minimize the impact on Box Elder Creek. From Mantua to the end of the project, the roadway would follow the same alignment and use the same design as under Alternative 1. Alternative 3 would be the same as Alternative 1 through Box Elder Canyon and to the summit. From that point, an entirely new six-mile alignment would be built, roughly following the old Sardine Canyon Road. This new alignment would require extensive new cuts and fills ranging up to 160 feet high. Blasting would be required for most excavation through the new alignment. The old roadway through Wellsville Canyon would be converted to unmaintained service roads, and the roadway through Dry Lake would be removed and the area restored to wetland habitat. A paved two-lane road would be constructed around the eastern perimeter of Dry Lake to provide access to the Sherwood Hills Resort. Alternative 4 would combine the North Box Elder alignment through Box Elder Canyon with the Sardine Canyon alignment. Alternative 2 is the preferred alternative. The estimated construction cost of this alternative is $28.6 million. POSITIVE IMPACTS: Project implementation would improve a connection between major population and economic centers along the Wasatch Front with communities of Cache Valley in northern Utah. As the most direct link between these centers, the route is used by the majority of travelers through the area. On a national level, S.R. 91 is a link in U.S. Route 89, which runs from Canada to Mexico. Access to heavily used recreational areas to the north in Utah, Wyoming, and Idaho would be improved. Highway safety also would be improved. NEGATIVE IMPACTS: Instream disturbance of 1,202 linear feet (12 percent of its length) of Box Elder Creek would occur during construction under alternatives 1 and 3. Loss of wetlands would be 8.5 acres, 8.4 acres, 2.9 acres, and 2.8 acres, respectively, for alternatives 1, 2, 3, and 4. Highway construction would displace 26 acres of agricultural land for alternatives 1 and 2 and 79 acres for alternatives 3 and 4. Alternative 1 or 3 would eliminate access to recreational fishing in Box Elder Creek at several locations. All alternatives would result in visual impacts from cut and fill. One to four sites of historic significance would be affected. Social impacts of substantial levels from loss of personal property and changes in lifestyle would result. Noise levels would impact 14 receptors for alternatives 1 and 2 and 15 receptors for alternatives 3 and 4. Traffic delays would be experienced during construction.

Preparation date: February 16, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - USH 45 (NEW LONDON BYPASS), OUTAGAMIE COUNTY, WISCONSIN: PROJECT I.D. 1146-4-00; F0007 ( ). AN - 36400139; 2524 AB - PURPOSE: Construction of an 8.6 mile bypass around the city of New London in Outagamie County, Wisconsin is proposed. The bypass would begin on USH 45 in the town of Hortonia, three miles south of the city of New London, and rejoin USH 45 two miles north of New London in the town of Lebanon. Ultimately, the facility would have two 12-foot driving lanes in each direction, with 10-foot outside shoulders, 6-foot inside shoulders, a 60-foot grassed median, and flanking ditch sections. A rights-of-way width of 250 feet would be required to contain this cross-section. Initially the project would be a two-lane roadway with 12-foot outside shoulders, although the earth grade for the four-lane cross-section could be developed in wetland areas and areas adjacent to river channels. Under either of two alternatives, the alignment would extend from its terminus, approximately three miles southeast of New London, follow existing USH 45 to within approximately 0.5 mile of the city's corporate limits before turning northeast to cross over the Fox River Valley Railroad tracks and proceed toward the New London Industrial Park. After skirting the edge of Mud Lake, the route would continue north of the lake, cross over River Road to enter the New London Industrial Park on its easterly side, and cross the Wolf River and County Trunk Highway ""S.'' At this point, the bypass would follow one of two alternatives. Alternative 1, labelled East ""A,'' would continue directly north to State Trunk Highway (STH) 54 and cross over the Embarrass River to meet existing USH 45 north of New London. Alternative 2, the preferred alternative, labelled East ""B,'' would proceed in a northwestern direction along the edge of the Wolf River floodplain to the Embarrass River at STH 54, follow the abandoned C.&N.W. R.R. rights-of-way, and join USH 45 north of New London. Both alternatives would encroach into the floodplains of the Wolf and Embarrass rivers. Interchanges and grade separation structures would be constructed to control access for either alternative. POSITIVE IMPACTS: Bypass construction would provide a connecting link for through traffic around the city of New London, eliminating the passage of regional traffic through the downtown area of the city. By the year 2013, the project, in combination with the downtown route, would handle an average daily traffic load of 18,600 vehicles, a significant percentage of which would be truck traffic; approximately 50 percent of the truck traffic would be expected to use the bypass. Accident rates on the existing facility, which have been above the state average over the past five years, and noise levels along the existing route would decline significantly. NEGATIVE IMPACTS: Depending on the alternative chosen, rights-of-way requirements of 219 to 222 acres of land would affect 10 to 11 farm operations, 13 residences, and 1 to 2 businesses. A mobile home located on the common leg of both alternatives would be acquired. The project would impact 35 to 45 acres of wetlands, and require placement of bridge support structures in the Embarrass and Wolf rivers and placement of fill in the rivers and associated marshes; as a result, habitat for sturgeon and numerous other fish species would be lost. High-value wildlife areas along the shorelines and upland areas associated with the Wolf and Embarrass rivers would be impacted. Minor, moderate, and severe noise impacts would affect eight to nine, six, and six receptors, respectively, but no violations of federal standards would occur at residential or business locations along the facility.

Preparation date: February 12, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FORT DIX BASE REALIGNMENT, INCLUDING FORTS BLISS, JACKSON, KNOX, LEE, BENJAMIN HARRISON, AND LEONARD WOOD, NEW JERSEY, TEXAS, SOUTH CAROLINA, KENTUCKY, VIRGINIA, INDIANA, AND MISSOURI. AN - 36383546; 2477 AB - PURPOSE: Fort Dix, in Burlington, Mercer, Monmouth, and Ocean counties, New Jersey has been proposed for realignment to semiactive status. This action would involve associated Army facilities, including Fort Bliss, Texas; Fort Jackson, South Carolina; Fort Knox, Kentucky; Fort Lee, Virginia; Fort Benjamin Harrison, Indiana; and Fort Leonard Wood, Missouri. The new status of the base would involve the transfer of entry-level training functions from Fort Dix to other Army installations located within the continental United States. More specifically, the plan would (1) transfer basic training at Fort Dix to Fort Knox, Fort Leonard Wood, and Fort Jackson; (2) consolidate basic training at Fort Bliss with basic training at Fort Jackson; (3) consolidate Fort Dix motor vehicle operator training at Fort Leonard Wood; (4) consolidate Fort Dix and Fort Leonard Wood light-wheeled vehicle mechanic training at Fort Jackson; (5) consolidate Fort Benjamin Harrison administrative and legal specialist training at Fort Jackson; (6) transfer Fort Jackson personnel specialist training to Fort Benjamin Harrison; (7) consolidate Fort Jackson supply specialist training at Fort Lee; and (8) consolidate Fort Dix and Fort Jackson food service specialist training at Fort Lee. In addition to the changes in training, each installation would either gain or lose personnel assigned to the Health Services Command and tenant activities located at the installations. Tenant activities occupy real estate at the various forts but are under the direction or command of another or higher authority. POSITIVE IMPACTS: Plan implementation would increase the availability of training areas at Fort Dix to support active and reserve training in the northeast. The combat readiness of troops trained at the facility would be assured. The local economy associated with Fort Knox and Fort Lee would benefit somewhat, while significant benefits would redound to the economies of communities associated with Fort Jackson and Fort Leonard Wood. NEGATIVE IMPACTS: Social and economic conditions in the local community associated with Fort Dix would decline significantly. Lesser socioeconomic impacts would occur in the local community associated with Fort Bliss. LEGAL MANDATES: Base Closure and Realignment Act of 1988 (P.L. 100-526).

Preparation date: February 2, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 58 MIDTOWN TUNNEL, CITIES OF NORFOLK AND PORTSMOUTH, VIRGINIA. AN - 36406760; 2523 AB - PURPOSE: Construction of a limited-access highway, including a tunnel, from Route 58 and the Western Freeway in Portsmouth to Brambleton Avenue in Norfolk, Virginia is proposed. The study area encompasses approximately 33 square miles and has a corridor length of approximately 3 miles. Beginning at the east end of the West Norfolk Bridge, the project would proceed eastward with a four-lane roadway for a distance of approximately 2,600 feet to an interchange with the Martin Luther King Freeway. The interchange would be located just west of the Portsmouth Marine Terminal and would be configured as a three-legged directional facility providing local access to the Portsmouth Marine Terminal and to the Port Norfolk section of Portsmouth. From the interchange, the project would proceed eastward under the Elizabeth River via a two-lane tunnel, marking an alignment that would parallel the existing two-lane Midtown Tunnel. The river crossing would have a length of approximately 4,200 feet, and the project would connect in Norfolk to an existing interchange with Hampton Boulevard and Brambleton Avenue. The estimated construction cost is $180.7 million to $193.6 million. POSITIVE IMPACTS: Traffic flow between the cities of Portsmouth and Norfolk from Route 58 and the east end of the West Norfolk Bridge in Portsmouth to Brambleton Avenue in Norfolk would be improved significantly. Traffic movement at the Midtown Tunnel crossing would benefit most due to the removal of long traffic queues. From a regional viewpoint, the new facilities would further implement the transportation planning of the area and, hence, improve overall traffic flow, traffic capacity, and travel time in the interests of economic growth and population mobility. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of two to seven businesses employing a total of 82 to 141 persons and a maximum of two residences. A total of 11.2 to 25.5 acres of rights-of-way would be developed, resulting in an annual tax loss of $45,000 to $104,000. Dredging of the main stem and the Western Branch of the Elizabeth River would be required, resulting in short-term degradation of water quality. Ambient noise levels would increase in the vicinity of the roadway, affecting residential properties, a hospital, and recreational facilities.

The goal of the five-year study was to develop a monitoring and modeling strategy for the New York Bight for use in documenting and predicting changes due to natural and human activities in the New York Bight The study plan was developed by the U.S. Army Engineer District, New York (CENAN), Operations Division, Water Quality Compliance Branch in coordination with the U.S. Army Engineer Waterways Experiment Station (CEWES), Vicksburg, MS, and the Office of the Chief of Engineers, Dredging Division. Three CEWES laboratories are involved: the Coastal Engineering Research Center, the Environmental Laboratory, and the Hydraulics Laboratory. In FY 89, a number of tasks were performed on initial evaluation of the New York Bight Database/Information System, Monitoring and Modeling Studies and Coordination. Much of the work centered on providing Information for and holding two technical workshops on monitoring and modeling (28 and 29 June 1989, and 11 and 12 July 1989, respectively). The workshops were held to focus the studies with assistance of scientific and engineering experts in the fields of monitoring and modeling. Results of the workshops which are presented below were used in study plans for updating and refining future Investigations.

In addition, urbanization often results In erosion problems as well as degraded water quality. Avoidance or minimization of these problems requires recognition, expertise and most importantly, early awareness on the part of management. All of the above elements are required to effectively manage and prolong the life of our reservoirs. Dam building agencies traditionally have not designed reservoirs, they have designed dams. Nearly the entire effort has gone into the design of the dam with little consideration given to the reservoir except as a volume to be filled with water. While the importance of safe dams cannot be overemphasized, the philosophy of considering the reservoir only as a volume to be filled with water has resulted in a multitude of problems which could have been minimized or avoided.

The degree of volatilization can be generally related to the vapor pressure of the compound: a compound with a high vapor pressure would volatilize rapidly, while one with a low relative vapor pressure would volatilize slower. To date, no simulative models have been developed to predict volatilization from a sediment/soil type material. The model presented in this paper provides an estimate of the mass of PCBs lost from an inlake and an upland Confined Disposal Facility (CDF). PCB was the only compound considered due to its regulatory significance and to simplify development of the model. It is anticipated that other semivolatile and volatile compounds such as polycyclic aromatic hydrocarbons (PAHs) will be modeled in the future for sediments contaminated with these substances. Typically, chemical equilibrium principles are used to determine the transfer of the volatile organic chemicals (VOCs) between various phases. In the case of VOCs associated with sediment, three phases of matter are involved. These are the solid particles which constitute the sediment and include both organic matter and mineral matter comprising the particles. The two other primary phases Include air and water (USACE, 1988). With respect to dredging, VOCs can enter the air from either the water or sediment surfaces. For volatilization to occur from the water surface, the VOC must first desorb from the suspended solids phase and diffuse through the water before being emitted into the air.

Whitewater releases from the project have been made since the early 1970's. The releases were generally made in late August or early September. The magnitude of the releases was about 800-1000 CFS and the length of the release was for three days (about 2,000 acre-feet of storage). Whitewater sports are growing rapidly in this area, and the demands for Whitewater releases from the Corps' reservoirs increase every year. A local group organized Whitewater Championships, Inc. (WCI) to promote Whitewater sports. WCI hosted the 1989 World Whitewater Canoe/Kayak Championship on the Savage River. The Savage River below the dam also is an outstanding trout stream. The project is regulated for the cold water fishery. As a result, about 5 miles of the river below the dam have become a trophy trout stream. Temperature control at Savage Dam is unique because the project has only a bottom release outlet works. The Baltimore District has successfully been able to managed the release temperature in an acceptable range for the fishery. This paper discusses the mode of operation for downstream temperature control, the change of operation due to Whitewater releases from 1987 to 1989, and its downstream temperature impacts.

From the point of major trifurcation to a point some 240 miles above the mouth, the depth is 55 feet or greater, except for a few short reaches aggregating no more than 20 miles located above New Orleans. In order to provide deep draft access to the potts of New Orleans and Baton Rouge, La., the largest distributary, Southwest Pass, must be dredged on a regular basis from the trifurcatlon some 20 miles to the Gulf of Mexico. A Joint venture by state and Federal agencies to increase the draft, below New Orleans, from 40 to 45 feet was completed in 1987. This required only the dredging of Southwest Pass. Historical records of saltwater intrusion into the Mississippi River indicate that river discharges of 300,000 cfs (cubic feet per second) or greater are capable of preventing intrusion into the river at the mouth of Southwest Pass. A discharge of 250,000 cfs will allow saltwater to advance into the river to the point of major trifurcation, commonly referred to as the Head of Passes. All distances are commonly referred to with respect to miles AHP (Above Head of Passes).

The U.S. Army Corps of Engineers is one such Federal agency that Is responsible for various aspects of a diverse water resources and shoreline protection program. The Corps recognizes that Its activities are likely to be affected by the hydrologic, meteorologic, and oceanographic consequences of global warming and expected climate changes. One response has been the explicit Introduction of risk analysis to aid in the evaluation and selection of alternative plans and project components to deal with natural hazard extremes and the mitigation of their social and economic consequences. This formal risk analysis is merely an addition to an existing multi-objective evaluation procedures that guide Federal water resources development These procedures are based on a body of social, economic, environmental, planning and decision theory literature that has been developed over the last 50 years.

Under direction of ER 1110-2-1941, drought management plans are prepared for each reservoir project. The Baltimore District's civil works boundaries Include the Susquehanna and Potomac River basins. There are 12 reservoir projects in the District containing controlled storage which could provide drought assistance. The District was divided into six subbasins for the purpose of preparing drought management plans. During a drought, the reservoirs in each subbasin are regulated In a system concept to achieve maximum benefits. This paper discusses the content of the drought management plans, coordination of the plans with other agencies, and effects of Implementation of drought management plans during the drought of 1988. In general, the drought management plans contain criteria for implementation of the plan, a modified reservoir regulation plan for drought management, and coordination of drought management activities with other agencies.

The confined disposal facilities (CDFs) considered Include an in-lake structure and three upland containment areas. In order to predict the quality of effluent from these CDFs, a water quality model was developed and run. The water quality model utilized input of several parameters which are dependent upon the operation of the CDF, including: the site-specific layout of the containment structure; the method of disposal (hydraulic, mechanical) and the physical arrangement of dredged materials within the CDF; the in-situ pore water quality of the sediment; and the percentage of pore water released from both saturated and unsaturated sediments during placement and rehandling within the CDF. Physical soil properties of the dredged sediments were utilized to quantify the pore water releases. Nitrification of ammonia nitrogen was simulated In the model, Including the effects of temperature on the nitrification rate.

The San Francisco Bay and estuary act as a critical thoroughfare for the nation's increasing role in Pacific Rim Trade with its numerous ports and intermodal links. Furthermore, the Bay and estuary, the largest coastal embayment on the Pacific coast of the United States, are also a significant habitat for anadromous and marine fish and other species that have a high economic and resource value to the region. Over the last twenty years, the competing needs of these different beneficial uses have become increasingly controversial. As of 1983, the San Francisco Bay Area was the fifth largest export manufacturing center in the United States with export-related employment of over 68,000 and a dollar value of close to 7 billion (Skinkle, 1989). In 1980, trade with the Pacific Rim nations (Japan, Korea, Taiwan, Australia and other countries in the Far East) accounted for one-quarter of the nation's imports/exports - today the share is over one-third and rising (Skinkle, 1989).

During an emergency, water may be required for a number of purposes as for public consumption. On this poster, results will be presented from two studies of emergency water planning conducted by the Detroit District of the U.S. Army Corps of Engineers. More specifically, several techniques developed to facilitate emergency planning for water systems at both the local and statewide levels and presented. These techniques include: a general hazard analysis procedure; EMERGE, a micro-computer model for assessing water supply source reliability; a critical component analysis procedure for assessing system vulnerability to major component failures; a water supply system database and database management system developed to assist in emergency planning and response; and a predictive to assist in estimating the operating requirements of water supply systems under both normal and emergency conditions.

The harbor Is underlain by sediments containing elevated levels of PCBs and heavy metals including copper, chromium, zinc, and lead. PCB concentrations in the sediment range from a few parts per million (ppm) to over 100,000 ppm and levels in harbor water have been measured in the parts per billion range (Weaver 1982). The source of the contamination was two electrical capacitor manufacturers who were major users of PCBs from the time their operations commenced in the 1930's until 1977. These Industries discharged wastewaters containing PCBs directly into the harbor and indirectly via the municipal sewer system (EPA 1976). In 1984 the Environmental Protection Agency (EPA) asked the Corps of Engineers (USACE) to evaluate the engineering feasibility of several dredging and disposal alternatives that had been proposed for the northern portion of the site, referred to as the Acushnet River Estuary. This 200-acre area extends from the Wood Street Bridge south to the Coggeshall Street Bridge (Figure 2) and contains the highest levels of contamination. An Engineering Feasibility Study (EFS) was conducted at the Waterways Experiment Station which consisted of field data collection, literature reviews, laboratory studies and modeling efforts leading to the development of conceptual alternatives for dredging and dredged material disposal (Franclngue 1988). The pilot study, which is the subject of this paper, is an extension of the EFS (NED 1989).

A thorough understanding of these impacts is essential to protection and effective management of multi-use waters supporting aquaculture facilities. This paper presents results of a three-year study conducted by the Tulsa District, U.S. Army Corps of Engineers (COE) aimed at assessing water quality-related impacts of aquaculture of channel catfish (Ictalurus punctatus) In floating net pens at Lake Texoma, Oklahoma/Texas. On 14 April 1987, an aquaculture research demonstration project was approved by the Assistant Secretary of the Army for Implementation at Lake Texoma The purpose of the project was to test the technical, operational, and economic feasibility of using Federal waters for commercial aquaculture. RedArk Development Authority (RedArk), a public trust and economic development organization serving a 21-county area of east-central and south-eastern Oklahoma, was licensed to construct and operate a net pen facility in the Rock Creek Arm of Lake Texoma for annual production and commercial sale of approximately 250,000 channel catfish. In addition to RedArk and the COE, agencies cooperating in the demonstration project included the Soil Conservation Service (SCS), U.S. Fish and Wildlife Service (USFWS), and Agriculture Research Service (ARS).

Thousands of miles of streams within western Pennsylvania, northern West Virginia, western Maryland, and southeastern Ohio have been degraded by an acid mine drainage (AMD) load that, until recent decades, was equivalent to more than a million tons/year of sulfuric acid. Severe AMD pollution caused damage by corroding pipes, pumps, boats, gates, and navigational aids. The acid and associated mineralization, along with frequent gross heavy metal pollution, degraded the aesthetic and recreational value of local waters. AMD suppressed and often totally eliminated aquatic life in impoundments and along substantial reaches of major rivers. AMD also caused numerous and serious domestic and industrial water supply problems.

The NYD has been dredging In the Port since 1888 and disposing of the dredged material offshore. Since 1914, dredged material has been disposed in the vicinity of the Mud Dump Site in the Atlantic Ocean, six miles east of Sandy Hook, New Jersey. This site was officially designated by the U.S. Environmental Protection Agency (USEPA) in 1984 as a dredged material disposal site. More than 90% of the 7-11 million cubic yards of sediment dredged annually from the Port of New York and New Jersey are disposed of at the Mud Dump Site. in the NYD, dredged material that is less than 90% sand and proposed for ocean disposal must satisfy the current USEPA/COE Ocean Dumping Testing Criteria (USEPA,COE 1977). The identification, bioassessment, water column/sediment interaction, and technical management of contaminants in dredged material is of major importance to the NYD's Federal and regulatory dredging programs. This paper will discuss the framework developed by the NYD to determine testing guidance values for dredged material contaminated with dioxin. Toxicologists, knowing the severe toxic effects of dioxin in experimental animals but being uncertain about comparable serious effects on people, call for more research. Environmental managers, who must make decisions based on this conflicting evidence, are left wondering what to do (Tschirley, 1986).

This $260 million, 10-year program Includes "a program for the planning, construction, and evaluation of measures of fish and wildlife habitat rehabilitation and enhancement." The UMRS-EMP is funded through Construction General. There are presently, within the St. Paul District (CENCS), 17 projects at various stages of planning, design, and construction, at an estimated construction cost of $19,573,000. These habitat rehabilitation and enhancement projects (HREP's) have been conceived by the Individual states and by the U.S. Fish and Wildlife Service. Many of these proposed HREP's are located in backwaters of the Upper Mississippi River where there are silt and clay substrates with low to moderate levels of contaminants. The program is characterized by tight time schedules, limited planning funds, and multiple projects being planned concurrently by different Federal and state agencies. A uniform, expedient, and economical approach to the evaluation of sediment contaminants was necessary. CENCS developed a Standard Operating Procedure (SOP) for sediment evaluation in this program for use within the St. Paul District.

Impacts due to deposition of overflow slurries would be limited to the channel side slopes and small areas of adjacent shallow bay bottoms. Recovery of benthic assemblages, encompassing newly recruited individuals of opportunistic species and pre-existing benthos able to vertically migrate up through thin overburdens of dredged material, would be rapid in affected habitats. If enhanced loading can be demonstrated from an economic standpoint, either by modification of existing equipment or improved dredging techniques, overflow dredging appears to be an environmentally acceptable option for future projects in the Mobile Bay system. Overflow operations in deeper estuaries, where dissimilar sedimentological and hydrodynamic conditions might create different dispersion and deposition patterns, should be treated as separate cases. Overflow dredging , however, deserves further consideration and study as a viable alternative for future dredging requirements.

AN - 36391273; 2512 AB - PURPOSE: Construction of a 16.9-mile multilane, divided highway, designated as Federal Aid Primary (FAP) 426 (Elgin-O'Hare Highway), from the east side of Elgin to an interchange with the proposed West O'Hare Expressway in Cook and Du Page counties, Illinois, is proposed. The purpose of this supplement to the draft environmental impact statement is to discuss revisions resulting from the change of the eastern project terminus from U.S. Route 12/45 to the proposed interchange of FAP 426 with the westerly bypass of Chicago-O'Hare International Airport. The terminus at the West O'Hare Expressway would lie at the west side of Chicago-O'Hare International Airport near Thorndale Avenue and York Road, while the terminus at Elgin would be the intersection of U.S. Route 20 (Lake Street) and Lovell Road. The preferred alternative would include intersections at Lovell Road, Bartlett Road/Oak Avenue, Park Boulevard, East Bartlett Road (North Avenue), Springinsguth Road/Illinois Route 19, Illinois Route 19, and Illinois Route 19/Rodenburg Road. Interchanges would be constructed at Church Road, U.S. Route 20, Gary Avenue, Rodenburg Road, Wright Boulevard, Roselle Road, Meacham Road/Medinah Road, Rohlwing Road, Interstate 290, Arlington Heights Road/Prospect Avenue, Wood Dale Road, and Illinois Route 83. The specific design of the interchange at Thorndale Avenue/York Road would be defined and evaluated in design and environmental studies for the West O'Hare Expressway. The highway design would include a 60-foot-wide median that could be used for high-occupancy vehicle and light rail transit development in the future. Traffic noise attenuation barriers would be included in the project design at Roselle, Elke Grove Village, and Hanover Park. The estimated cost of the project is $350 million in 1989 dollars. Due to funding limitations, a staged construction plan would be implemented. POSITIVE IMPACTS: The proposed highway improvement would provide needed traffic capacity in the corridor between Elgin and Chicago-O'Hare International Airport, relieving local arterial traffic congestion. Long-term employment would be generated by construction of FAP 426. Property values would rise due to increasing population and economic growth, and improved accessibility would stimulate more efficient use of existing business, commercial, industrial, and manufacturing land uses. Air pollution from automobile emissions would be reduced. NEGATIVE IMPACTS: The project would require approximately 37 residential, 8 commercial, and 1 industrial relocations. Six streams would be crossed by the proposed alignment, resulting in erosion of soil and subsoil into the streams. The loss of wetlands would amount to 42.4 acres. Numerous residential receptors would experience traffic noise equal to or greater than the federal noise abatement criteria for residences. Two houses of local historical significance, which could be eligible for the National Register of Historic Places due to significant archaeological and architectural features, would be displaced. Spillage of oils, grease, and fuel during construction could adversely affect surface water quality.

Preparation date: January 31, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DAVIDS ISLAND PROJECT, LONG ISLAND SOUND, NEW ROCHELLE, WESTCHESTER COUNTY, NEW YORK. AN - 36399540; 2539 AB - PURPOSE: Development of Davids Island, located in the western section of Long Island Sound in the city of New Rochelle, Westchester County, New York, is proposed. The Davids Island Urban Renewal Area consists of Davids Island and a 2.3-acre portion of the Fort Slocum Dock area. Davids Island encompasses 77.8 acres of land above mean high water (MHW), of which 42 acres are above the 100-year flood elevation. With the exception of 5.2 acres owned in fee simple by Consolidated Edison, Davids Island is owned by the city of New Rochelle. The proposed development of Davids Island as a residential community would include 2,000 residential units and supporting neighborhood retail, recreational, and open space uses; construction of a marina, breakwater, beach, private sewage and treatment plant and outfall; provision of utilities; construction of a helipad; construction of a mainland parking garage and a bridge from the mainland to the island and associated bridge access roadways on the mainland; and improvements to the South Channel. The fixed-span bridge would be 3,465 feet long, commencing at the Fort Slocum Dock area and proceeding in an easterly direction along a route that brings the structure adjacent to the most northern area of Glen Island and over a 0.48-acre area of parkland that is normally covered with water at MHW and partially exposed at mean low water. Two bridge pile foundations would be placed within this area. The mainland approach to the Davids Island Bridge would be designed to provide one-way circulation on the mainland. This approach system would provide for all traffic entering Glen Island, Davids Island, the Huguenot Yacht Club, the Glen Island Yacht Club, and adjacent residences to use the Glen Island Approach Roadway. Exiting traffic would use Fort Slocum Road. The residential units would be situated within four high-rise structures; three of these high-rise structures would be located in the northern portion of the site, while the remaining structure would be located in the central portion of the site. None of the high-rises would exceed 31 floors. Population on the island is projected to be 3,700 persons. The western and southern shoreline of the island would be developed as a marina accommodating 800 slips for use by island residents. POSITIVE IMPACTS: The city of New Rochelle would derive substantial economic benefit from the development of Davids Island. The long-term consequences of developing the island represent a conversion from its current status as undeveloped, underutilized, and blighted lands. Access to and from Westchester County's Glen Island Park would improve, and traffic backup on local streets would be reduced. New jobs, income, and housing would be produced. There would be a substantial increase in public tax revenues over and above public costs for the project, and New Rochelle's image would improve as a waterfront community in proximity to New York City. NEGATIVE IMPACTS: The primary negative impacts resulting from the development would include navigational and boating constraints associated with the clearance restrictions of the Davids Island Bridge; increased project-related traffic volumes on the mainland roadway system, with consequent increases in vehicular exhaust emissions and vehicular noise; the need for additional sewage treatment capacity at the New Rochelle plant; and impacts to the marine environment from dredging and rock blasting.

Preparation date: January 30, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - EAST UNIT ACCESS ROAD AND US 12 RELOCATION, LAPORTE COUNTY, PORTER COUNTY, AND MICHIGAN CITY, INDIANA: PROJECT NO. ID-94-2(62) AND NPS-M-H829(2). AN - 36391305; 2513 AB - PURPOSE: Construction of the East Unit Access Road from Interstate 94 (I-94) on the south to US 12 on the north and relocation of US 12 between the Woodlawn Avenue/County Line Road intersection and the Sheridan Avenue intersection, all within LaPorte and Porter counties, in the vicinity of Michigan City, Indiana, are proposed. The 2.6-mile East Unit Access Road would begin on the south with a new intersection at I-94 and follow an alignment along or adjacent to the LaPorte /Porter county line west and southwest of Michigan City to US 12. The relocated section of US 12 would begin on the west at the US 12 /Woodlawn Avenue/County Line Road intersection and extend east 1.2 miles along Woodlawn Avenue and then north along the east side of the Northern Indiana Public Service Company's power transmission corridor to a project terminus near the present US 12/Sheridan Avenue intersection. The East Unit Access Road would be a four-lane, divided rural arterial highway within a 300-foot right-of-way providing partially controlled access. It would include an interchange at I-94, bridges spanning two railroads, and a hiking/biking trail, with a trailhead near Kieffer Road. The relocated section of US 12 would consist of a four-lane roadway within a minimum right-of-way of 100 feet and would feature curbs and gutters and a bridge over the Chicago, South Shore, and South Bend Railroad tracks. POSITIVE IMPACTS: Overall north-south roadway capacity between I-94 and the north end development/Lake Michigan lakefront in Michigan City would be increased, diverting local and nonlocal traffic from Franklin Street and preventing future congestion on that arterial roadway. The new roadways would serve the Indiana Dunes National Lakeshore by connecting I-94 with the East Unit of the National Lakeshore. NEGATIVE IMPACTS: Rights-of-way development would displace a maximum of 5 commercial units and 22 residential units, and some residences would be exposed to increased noise levels and visual intrusions resulting from roadway structures. Rights-of-way development would displace approximately 21 acres of wetlands, and construction disturbances would affect an additional 15.2 acres. One threatened plant species could be affected by construction. Approximately 109 acres of prime farmland would be affected by rights-of-way acquisition. Noise levels would exceed federal standards at numerous sites. Travel patterns on some local roads would be altered due to the possible closure of 8th Street at US 12 and the closure of Sheridan Avenue at US 12. Carbon monoxide increases for the East Unit Access Road and US 12 relocation would be 0.2 and 0.4 parts per million, respectively.

Preparation date: January 30, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SAUGUS RIVER AND TRIBUTARIES FLOOD DAMAGE REDUCTION, LYNN, MALDEN, REVERE, AND SAUGUS, MASSACHUSETTS. AN - 36404613; 2537 AB - PURPOSE: Implementation of a plan to control coastal flooding problems along the coastal floodplain of the Saugus River and its tributaries in Massachusetts is proposed. Lying approximately 5 to 10 miles north of Boston, the 4,000-acre study area includes portions of the cities of Lynn, Malden, and Revere and the town of Saugus; the area has a resident population of 20,000 persons. The study area frequently suffers from coastal flooding. The recommended regional plan would combine three miles of existing flood damage reduction measures with 3.5 miles of new measures to create a linked defense line that would provide protection against the Standard Project Northeaster to nearly the entire study area and prevent flooding up to 10 feet deep. The principal component of the plan would involve construction of tidal floodgates at the mouth of the Saugus River that would prevent tidal surges from entering the river and flooding land throughout the study area. The floodgates would span 1,300 feet at the mouth of the river and include 730 feet of gated openings so as to maintain both safe passage for navigation and natural tide levels and flushing patterns in the estuary. The gates would be closed only when projected tide levels are expected to cause significant damages. Closure would generally occur two to three times each year, with an average closure lasting one to two hours during the peak of each tide. During very severe coastal storms, such as a recurrence of the blizzard of 1978, the gates would be closed for longer periods and possibly for more than one high tide. If the sea level should rise, generally, the frequency of closures would increase. A combination of dikes, walls, stone revetments, beaches, and sand dunes would be developed at Lynn and Point of Pines. Preservation of three miles of existing seawalls at Revere Beach, as well as construction of a wall and a park dike behind that beach would also be needed. The $85.1 million plan would have an average annual cost of $8.6 million, including $230,000 per year for operational costs, maintenance, and major replacements. The estimated benefit-cost ratio is 1.3. POSITIVE IMPACTS: Flood damage prevented by the project would result in average annual benefits worth $11.0 million, for an average annual net benefit of $2.3 million. Flood damage would be reduced for 5,000 buildings and the associated infrastructure, including 20 miles of floodprone public transportation arteries. The need for and cost of emergency public services would decline significantly. The project would provide public parkland along the 3,400-foot dike. A safe port of refuge during coastal storms would be provided for the 400-vessel fleet moored in the estuary. NEGATIVE IMPACTS: Project activities would result in the loss of approximately 10 acres of mostly intertidal habitat at the location of project features along the coast; this loss would be mitigated through the creation of 10 acres of clam flats at the Interstate 95 embankment. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.) and River and Harbor Act of 1902.

Preparation date: January 25, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DIAMOND CHUITNA COAL PROJECT, SOUTHCENTRAL ALASKA. AN - 36391423; 2483 AB - PURPOSE: Issuance of a permit to the Diamond Alaska Coal Company is proposed for the development of the Diamond Chuitna Coal Project, to be located on the west side of Cook Inlet in southcentral Alaska. The project would consist of a surface coal mine, a haul road, a means of transporting coal to a port facility on Cook Inlet, dock facilities, and other ancillary facilities. The preferred alternative would involve construction of a port site at Ladd, development of an eastern transportation corridor, development of a housing facility at Lone Creek, and installation of a conveyor system that would parallel the haul road and transport coal to the port site. Full development of the Diamond Chuitna coal project would involve a 10.9-million-metric-ton (12.0 million short tons) per year surface coal mine in the Beluga area, approximately 72 kilometers (45 miles) west of Anchorage. The coal to be mined would be subbituminous, low-sulphur, low-ash, high-moisture steam coal with an average of 4,250 kilocalories per kilogram (7,650 British thermal units per pound). The actual area to be mined during the projected 34-year life of the project would cover approximately 2,029 hectares (5,014 acres), with a maximum of 182 hectares (450 acres) of pit being open at any one time. Mining methods would involve the use of shovels, draglines, hydraulic backhoes, front-end loaders, and haul trucks. Coal would be crushed at the mine and carried to a 22-hectare (55 acres) mine service area by conveyor for further crushing and weighing. The coal would then be transported approximately 11 miles by a single-span, 48-inch-wide conventional conveyor to a port site on Cook Inlet, located either at Granite Point south of the mine or at Ladd east of the mine. The conveyor would be paralleled by a light-duty maintenance road and an all-weather gravel access/haul road. The onshore port facilities would occupy approximately 121 hectares (300 acres) on the bluff above Cook Inlet at either Granite Point or Ladd. As much as 1.1 million metric tons (1.2 million short tons) of coal would be stockpiled at the port for shipment. At full production, the offshore port facility would consist of an elevated trestle up to 3,810 meters (12,500 feet) long, and would support twin conveyors for loading coal ships. The work force would be housed in permanent single-status housing and community facilities on an 8-hectare (20 acres) site north of the Chuitna River. The project would include a reclamation plan. Although placement of the onshore port facilities at the Ladd site is the primary preferred alternative, a site at Granite Point could be chosen, due to potential conflicts resulting from a transport corridor crossing of Tyonek Native Corporation land should the Ladd alternative be chosen. POSITIVE IMPACTS: Coal produced by the project would assist in providing for the energy needs of the local area and the region. Increases in employment and other socioeconomic enhancements would benefit the local economy. NEGATIVE IMPACTS: Project components would disturb approximately 2,029 hectares (5,014 acres) of vegetated terrain. Due to ongoing reclamation of mined areas, the actual unvegetated surface at any one time would be substantially less. Approximately 24 percent of the disturbed area would be wetlands. Wildlife impacts would include the loss of habitat during the life of the mine and for a period following termination of mining activities. Moose, brown bear, and black bear would be affected, as well as small mammals and birds. The loss of moose winter range at the proposed port site and a portion of a rutting area in the vicinity of the mine would also occur. Movement of large animals would be impeded by the conveyor system. Loss of fish productivity, including productivity of such key species as chinook and coho salmon, would occur during the mining operation. The return of mined-out streams to their original condition would be problematic. Some disruption of subsistence activities would be likely.

AN - 36403751; 2496 AB - PURPOSE: Construction and operation of a destination resort on private land within the Toiyabe National Forest and Washoe County, Nevada is proposed. Application for a special-use permit for a long-term lease of 633 acres of national forestland adjacent to the development site would also be made. The resort would be located in the upper Galena Creek basin, approximately 17 miles from Reno. At ultimate development, the resort would consist of three villages containing hotel and residential units and commercial space, as well as conference facilities, casinos, restaurants, entertainment areas, and retail space, along with the associated infrastructure. Hotel/residential units would include 720 hotel rooms, 1,460 multifamily residential units, 100 single-family units, and 265,000 square feet of commercial space and conference areas. Recreation amenities would include a 15-lift downhill ski area, Nordic skiing provisions, ice skating facilities, an 18-hole golf course, tennis courts, and other sports/recreational provisions. Infrastructural requirements would include water and sewer pipelines, roads, and underground utility cables. Construction would be phased over 15 to 17 years. The first phase of the development, which would extend through the fifth year of development, would include the initial components of one village, approximately one-half of the ski area, and the golf course. The opening ski area would have a capacity for 5,560 skiers, using 257 acres of trails and six ski lifts. Average annual construction thereafter would consist of approximately 150 unit equivalents and 20,000 square feet of commercial space. Depending on future conditions, the number of units and density could vary somewhat in accordance with the previously approved Washoe County special-use permit. The ultimate three-village complex would be linked by roadways and recreation systems to create a cohesive destination recreational resort community. Of the three communities, one would serve as the hub and the other two as support lodging communities. POSITIVE IMPACTS: A profitable destination resort would be developed, based on existing market research. The facility would further the goals of the Nevada State Comprehensive Outdoor Recreation Plan. The economic base of the state and the county would be diversified. NEGATIVE IMPACTS: Development of the site would disturb up to 1,238 acres of wildlife habitat, including 5.5 acres of wetlands. Habitat continuity along 1.3 miles of Galena Creek canyon would be disrupted temporarily, and 250 linear feet of the streambed and 950 linear feet of adjacent vegetation would be disturbed. The view of the area from Mt. Rose and the Mt. Rose Trail would be altered. The level of total suspended particulates would increase by 0.21 ton per day due to the use of woodburning fireplaces. During operation of the resort, carbon monoxide standards would be exceeded during worst-case peak hours. Erosion would increase by 150 to 450 tons per year. Approximately 475 acre-feet would be removed from groundwater resources and 315 acre-feet from Galena Creek annually; the quality of water in Galena Creek would decline due to urban runoff. Traffic volumes in Tahoe Basin would increase, particularly during winter weekend peaks. Construction activities would exceed local federal standards for carbon monoxide and particulates.

AN - 36402301; 2476 AB - PURPOSE: Implementation of a plan to refocus the primary mission of Fort DeRussy in the city and county of Honolulu, Oahu, Hawaii is proposed. The refocusing project would change the primary mission of the facility from coequal support for the U.S. Army Reserve and all-service recreation activities toward a primary mission of recreation. Most Army Reserve functions would be moved to Fort Shafter. The proposed action would involve demolition of selected facilities; extensive landscaping of the Army post; construction of a new 400-room, 12-floor hotel tower and new 1,200- and 1,400-stall parking structures; and realignment and widening of Kalia Road. Development of the Armed Forces Recreation Center at Fort DeRussy would emphasize shared military-community use of many of its facilities. The land use plan for the approximately 72 acres within Fort DeRussy would include 35 acres for hotel and beachfront activities; 25 acres for parks and other recreational land; 6 acres for multilevel parking; 3 acres for Army Reserve facilities, which would ultimately be converted into parkland; 1.6 acres previously outgranted for the existing U.S. Post Office; and 1 acre for base support activities. POSITIVE IMPACTS: The project would support and expand the recreational mission of Fort DeRussy, which has functioned as a recreational facility since World War II. Military personnel serving throughout the entire Pacific Rim would be served by these facilities. Currently, numerous requests for recreational leave at Fort DeRussy and nearby recreational facilities must be denied. Acres of open space available for use within Fort DeRussy would increase significantly. Fort DeRussy would continue to serve the local community as a primary historical location for numerous cultural and recreational events. NEGATIVE IMPACTS: Areas that are now undeveloped or developed with low-relief structures would be replaced with two multistory parking structures and a new 12-floor hotel tower, significantly affecting the viewscape. The parking structures would adversely affect scenic views of pedestrians and vehicular passengers using Kalia and Saratoga roads. Construction activities would result in temporary disruption of fort activities.

AN - 36400183; 2525 AB - PURPOSE: Improvement of a segment of U.S. Highway (USH) 53 in Washburn and Douglas counties, Wisconsin is proposed. The project would upgrade USH 53 from its present two-lane configuration to a four-lane expressway from a point 0.5 mile north of the intersection of USH 63 at Trego northward for a distance of 43.9 miles to a point approximately 0.1 mile south of the intersection with Kent Road in the town of Hawthorne. Frontage roads, bridges, and grade separation structures would be provided as necessary to meet expressway standards. Some sections of USH 53 would be realigned and/or relocated. The rights-of-way width would most likely be 300 feet for relocated sections and 250 feet for those segments where the existing highway corridor would be simply expanded to the east or west. The highway project has been divided into eight segments, each of which is described in detail in this environmental impact statement. Project costs and impacts are presented by section. POSITIVE IMPACTS: A gap between two four-lane expressway segments of USH 53 would be closed. The resulting facility would be consistent with existing and future regional and interstate transportation system goals. Additional continuity in a multilane highway system between Interstate 94 (I-94) at Eau Claire and I-35 in Duluth would be provided, and a more efficient connection between the two major population centers would be available. Forest, mineral, and recreational resources of northwestern Wisconsin would be more accessible. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of residences, nonprofit organizations, and businesses, as well as woodland, wetland, and agricultural land. Noise levels along the corridor would exceed federal standards at some locations. Archaeologically significant resources would be disturbed. Widening of the facility could hinder the movements of an endangered species, the timber wolf.

Preparation date: January 12, 1990 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOCAL FLOOD PROTECTION, MOOREFIELD, HARDY COUNTY, WEST VIRGINIA. AN - 36399729; 2538 AB - PURPOSE: Implementation of a flood protection project for the town of Moorefield, located in Hardy County, West Virginia, is proposed. Moorefield is located along the South Fork and South Branch Potomac River. The recommended plan would involve construction of a levee system that would provide 100-year flood protection for both North and South Moorefield. More specifically, the recommended plan would include 22,035 feet of earthen levee, 1,290 feet of floodwall, reconstruction of the South Branch Valley Railroad bridge at a higher elevation, environmental and cultural mitigation, and appurtenant project features such as ramps, closures, riprap, and relocations. The project design would include a flood warning system built on the existing IFLOWS (Integrated Flood Observing and Warning System). Mitigation measures incorporated into the project design would include planting of high habitat value trees and shrubs. The estimated duration of the preconstruction engineering and design phase, which would follow the current feasibility phase, would extend over three years. The estimated first cost, including future price escalations through project completion, is estimated at $16.1 million. Average annual costs and benefits are estimated at $1.4 million and $1.7 million, respectively, for a benefit-cost ratio of 1.25. POSITIVE IMPACTS: Plan implementation would prevent approximately 84 percent of the potential average annual flood damages in Moorefield. Local interests support the recommended plan and view it as a cornerstone in the economic redevelopment of the Moorefield area following a catastrophic 500-year flood in November 1985. Net annual benefits redounding from the project would be worth $349,000. NEGATIVE IMPACTS: Land acquisition for project development would require displacement of five mobile homes, four permanent homes, a lumber yard, a junk yard, and a slaughter house in North Moorefield and nine mobile homes, a two-story wooden house, the Old Mill Apartments, one of the Fertig Cabinet Company buildings, and the Old Mill in South Moorefield. Relocation of a sewerage pump station and various utility lines would also be required. Approximately 1.7 acres of bottomland hardwood would be displaced, and levee placement would permanently occupy approximately 20.9 acres of land consisting primarily of abandoned farmland, cultivated fields, pastures, and urban land.

AN - 36407687; 2534 AB - PURPOSE: Construction of a 1,050 acre-foot impoundment, to be known as O'Hare Reservoir, is proposed to store storm water from the Tunnel and Reservoir Plan tunnel system of the Metropolitan Water Reclamation District (MWRD) of Greater Chicago, Cook County, Illinois. O'Hare Reservoir would provide flood damage reduction in the 11.2-square-mile O'Hare combined sewer area, which includes more than 21,000 housing units providing residences for some 61,400 persons. Currently, combined sanitary and storm runoff is conveyed to MWRD's O'Hare Water Reclamation Plant via large tunnels located up to 130 feet below ground level. Major components of the project include reservoir excavation, the reservoir lining, excavated material disposal, an inflow/outflow structure, a flushing system, an aeration system, a groundwater control/grout wall, an underdrainage system, access and haul road construction, creek and wetland relocation, and utility relocation. The reservoir would be excavated to the top of the bedrock approximately 84 feet below the existing ground elevation of +80 feet Chicago City Datum (CCD) (0 feet CCD is equal to 579.5 feet National Geodetic Vertical Datum). The reservoir would occupy approximately 30 acres at ground elevation. When filled to its maximum capacity, the reservoir would have a water surface level at 22 feet below surface elevation. The reservoir would have a 15-foot-wide bench at elevation +8 to -2 CCD and side slopes of 1 on 2 (rise on run) both above and below the bench. A total of 2.6 million cubic yards of material would be excavated from the reservoir using large bulldozers and scrapers. The material would be placed on two 100-foot spoil piles having side slopes of 1 on 2.5. The estimated first cost of the project is $20.5 million. Annual operation and maintenance costs are estimated at $65,400. The average annual cost of the project is estimated at just under $2.0 million, while average annual benefits are valued at $2.3 million, for a benefit-cost ratio of 1.15. POSITIVE IMPACTS: By storing storm water, the O'Hare Reservoir would provide flood relief, reducing basement and street flooding caused by sewer backup. The project would also provide water quality benefits by reducing combined sewer overflows into Weller Creek. NEGATIVE IMPACTS: A tributary of Willow-Higgins Creek on the site would be relocated. Loadings of suspended sediments in the west branch of Higgins Creek would increase during construction. Benthic fauna in a cut-off reach of the west branch of Higgins Creek would be lost, and an entire aquatic community would be lost in the south branch. One archaeological site would definitely be displaced. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.), and Water Resources Development Act of 1986 (P.L. 99-662).

AN - 36406712; 2519 AB - PURPOSE: Construction of a 5.5-mile extension of the 6th and 7th avenue couplet on new alignment in the city of Eugene, Lane County, Oregon is proposed. The project would consist of two segments. The eastern terminus of the project would be a connection to Pacific Highway West (99W) north of West 5th Avenue. The western terminus of the project would lie just beyond the Green Hill Road intersection with Goble Road. Four cross-sections would be included in the project design. For the most part, between Seneca Road and the western terminus, the typical section would have four 12-foot lanes, a 14-foot median, and 8-foot shoulder bikelanes. One section would feature four 12-foot lanes, a 14-foot median, 8-foot shoulder /bikelanes, and 5-foot sidewalks with curbs. A third section, between West 6th and 7th avenues, would have two 12-foot travel lanes, a 4-foot shoulder on the south side of the roadway, a 6-foot shoulder on the north side of the roadway, and 5-foot sidewalks with curbs. From 5th Avenue to Garfield Street, the existing 6th and 7th avenue roadways would be reconstructed within existing rights-of-way to a width of 46 feet, with curb and sidewalks on both sides. Rights-of-way widths would range from 70 to 190 feet. The estimated cost of the project is $20.4 million. POSITIVE IMPACTS: The project would serve the city of Eugene's economic diversification plans. The corridor would provide access for the development of an additional industrial and business base, inducing economic growth along either side of the respective proposed alignments. Improved east-west traffic flow would improve access to the West Eugene industrial area. NEGATIVE IMPACTS: Rights-of-way development would displace 80 acres of land, 5 to 9 businesses, and 2 homes; 60 properties would be affected. Approximately 28 acres of wetlands would be impacted, and the Amazon Creek floodplain would be traversed, requiring fill in 13 acres of floodplain. Habitat conditions for endangered plant species also could be affected.

The land exchange would involve approximately 15,960 acres of public land and 13,410 acres of private land on a surface-estate-only basis. The generating units would be designed for baseload duty, but would also have cycling capability. Each 250-MW generating unit would be fueled by coal delivered via train from mines at Kemmerer, Wyoming and Scofield, Utah. Each unit would require one 55-car unit train to deliver fuel at five-day intervals from the Scofield mine and at four-day intervals from the Kemmerer mine. A rail spur would connect the station site to the Southern Pacific Railroad. Four to five 55-car unit trains would deliver coal to the plant site each day when all eight units are operating. Plant operation would also require approximately 32,000 acre-feet per year of water to be delivered; this water would be used primarily for cooling plant equipment. Plant water supply would be groundwater from the project's proposed wellfields, to be developed in Toano Draw and the valley of Thousand Springs Creek. It would be likely that lime spray scrubber systems, low-nitrogen oxide burners, and baghouses would be used to control sulfur dioxide, nitrogen oxides, and particulates, respectively; in any event, the best available control technology would be used to reduce emissions. Transmission lines would also be included in the general project design. Market demand would determine the timing for construction of each unit, although two-year intervals are expected. Each unit would be designed to operate for 35 years, with operation of the first unit beginning in 1994. Operation of the last unit would cease in 2043. POSITIVE IMPACTS: The land exchange would allow for consolidation of a contiguous block of private land on which the power plant complex could be constructed and operated. The generating company would use the station to produce competitively priced electrical energy to be sold to utilities in Nevada, California, Oregon, Washington, and Idaho. The construction work force would peak at 800 workers in 1993. On completion, the plant would employ 560 workers. NEGATIVE IMPACTS: Approximately 1,780 acres of land would be disturbed at the power plant site and for rights-of-way acquisition for the access road, railroad spur, and water pipeline. Power plant emissions would reduce local air quality, but federal standards would not be violated. Facility construction would displace soil and vegetation from the site and utility and transportation corridors, thereby reducing wildlife and livestock forage and habitat. Groundwater withdrawals and human encroachment could result in impacts to springs, ponds, and wetlands located near the wellfields. During extended dry periods, Dake Reservoir could be emptied completely, significantly affecting the associated fishery. Archaeological sites could be disturbed or destroyed. Generating facilities would intrude visually on an otherwise natural landscape. Approximately 15,000 acre-feet per year of irrigation water would eventually be phased out. The influx of workers and their families would place some stress on the city of Wells and regional recreation resources.

AN - 36409440; 2484 AB - PURPOSE: Three proposed hydroelectric projects that would produce an annual total of approximately 450 gigawatt-hours (GWh) of electric power and would be sited on the mainstem of the Snake River near Twin Falls, Idaho have been evaluated for their environmental effects and economic benefits. Applications for licenses to construct, operate, and maintain the three proposed projects were filed by Idaho Power Company (FERC No. 18) for a new license with expanded capacity, Cogeneration, Inc. (FERC 4797), and B&C Energy, Inc. (FERC No. 5797). Additionally, potential modifications to the licensed Milner Project (FERC No. 2899), arising from studies required in the license, were evaluated so as to fully utilize the water power resource. These modifications would produce an additional 33 GWh annually. The projects would be located along a 32-mile stretch of the river in the Upper Snake River Basin, a large, sparsely populated, diverse area that includes most of south-central Idaho. Each license would allow a nonutility licensee to construct its proposed project after securing a contract for the sale of power from, and securing financing for, its proposed project. Projects to be licensed would include (1) the Star Falls Project, to be located 8 miles downstream of Milner Dam; (2) the existing Twin Falls Project, to be located 3 miles upstream of Twin Falls; and (3) the Auger Falls Project, to be located 3 miles northwest of Twin Falls. The Milner, Star Falls, and Twin Falls projects would include dams and reservoirs, while major structures at the Auger Falls project would consist of a concrete diversion dam, overflow weir, and power canal. All projects would feature run-of-river designs, and transmission facilities would be constructed in association with the generation facilities. This draft supplement to the draft environmental impact statement also addresses the potential modifications to the Milner Project, which would involve the addition of a bypass powerhouse at the dam. The Milner Project would have two generating units, a hydraulic maximum capacity of 4,000 cubic feet per second (cfs), a minimum capacity of 900 cfs, and an annual generation output of 177.0 GWh. The Star Falls Project would have one generating unit, a maximum hydraulic capacity of 5,500 cfs, a minimum capacity of 1,000 cfs, and an annual generation output of 112 GWh. The Twin Falls Project would have one generating unit, a maximum capacity of 4,960 cfs, a minimum capacity of 1,000 cfs, and an annual generation output of 189.0 GWh. The Auger Falls Project would have three generating units, a maximum capacity of 5,000 cfs, a minimum capacity of 200 cfs, and an annual generation output of 149.0 GWh. A fish ladder would be constructed in association with the Auger Falls Project. Other mitigation measures implemented in association with the projects would include the formation of river islands, erosion sedimentation controls, construction of surface drainage swales, development of wildlife ponds, creation of other wetland areas, construction of osprey nesting platforms and goose nesting structures, extension of cattle-guard fencing, use of transmission structure designs that would prevent electrocution of large raptors, and development of artificial burrows for owls. Provisions for recreational access to the river would be made at several locations. Project construction schedules range from 19 months to 3 years. The preferred action is the licensing of the Twin Falls and Auger Falls projects, with staff-recommended mitigation, denial of a license for the proposed Star Falls Project, and amending the Milner Project license to include a bypass powerhouse at the base of the dam and an expanded capacity at the main powerhouse. POSITIVE IMPACTS: Operation of the projects would improve the reliability of the power supply infrastructure in the region and provide a portion of the additional electrical energy requirements estimated for 1992 and beyond. Local and regional economies would be boosted, and fulfillment of federal power requirements would be supported. NEGATIVE IMPACTS: Implementation of the projects would have significant impacts on resident trout populations, wintering waterfowl, raptors, riparian-associated wildlife and vegetation, water quality, visual quality, and recreational and cultural resources.

AN - 80410302; 1368145 AB - The extensive use of phosphate-based detergents and agricultural fertilizers is one of the main causes of the world-wide eutrophication of rivers and lakes. To ameliorate such problems partial or total substitution of phosphates in laundry detergents by synthetic, non-phosphorus containing complexing agents is practiced in several countries. The physiological, biochemical and ecological aspects of the microbial degradation of the complexing agents most frequently used, such as polyphosphates, aminopolycarboxylates (especially of nitrilotriacetic acid), and phosphonates are reviewed.

AN - 80410210; 1368140 AB - A Gram-negative bacterium was isolated from river sediment which was able to grow with nitrilotriacetic acid as a combined carbon, nitrogen and energy source in the absence of molecular oxygen using nitrate as the terminal electron acceptor. Batch growth parameters and mass balances are reported for growth under both aerobic and denitrifying conditions. The strain was characterized with respect to its substrate spectrum and other physiological properties. This denitrifying isolate is serologically unrelated to the comprehensively described Gram-negative obligately aerobic NTA-degrading bacteria all of which belong to the alpha-subclass of Proteobacteria. Chemotaxonomic characterization, which revealed the presence of spermidine as the main polyamine and ubiquinone Q-8, excludes the new isolate from the phylogenetically redefined genus Pseudomonas and indicates a possible location within the gamma-subclass of Proteobacteria close to, but separate from the genus Xanthomonas.

AN - 80128156; 2244785 AB - A bacterium tentatively identified as a Pseudomonas sp. was isolated from a laboratory aquifer column in which toluene was degraded under denitrifying conditions. The organism mineralized toluene in pure culture in the absence of molecular oxygen. In carbon balance studies using [ring-UL-14C]toluene, more than 50% of the radioactivity was recovered as 14CO2. Nitrate and nitrous oxide served as electron acceptors for toluene mineralization. The organism was also able to degrade m-xylene, benzoate, benzaldehyde, p-cresol, p-hydroxy-benzaldehyde, p-hydroxybenzoate and cyclohexanecarboxylic acid in the absence of molecular oxygen.

In the case of the Los Angeles County Drainage Area (LACDA), California, urbanization impacts are further complicated by upstream regulation (debris basins, water supply dams, and flood control dams and channels) constructed during this period. The system operation requirements make it a virtual necessity to use a rainfall-runoff model to compute reservoir inflow and simultaneous runoff in downstream subareas. The rainfall-runoff model is linked to a reservoir routing model to determine reservoir releases and combine these with downstream runoff. Discrete event rainfall-runoff analysis provides estimates of a range of peak flood flows throughout the basin, and also makes available flood hydrographs at any location of interest. The basis of this approach--frequency rainfall and subarea runoff calibrated to observed flow--provides a sound basis for computation of frequency runoff. The dynamics of urbanization are quantified by establishing a 'current' discharge-frequency relationship for observed flow for urbanized locations. The rainfall-runoff model linked to a reservoir operation model was able to replicate these flood flow trends, especially in the downstream reaches. Since the upstream flows were calibrated to observed results, and since simulation agreed with the observed flows, it is reasonable to expect that the intermediate results are also representative of existing conditions. Furthermore, the modeling process provides these frequency discharges and hydrographs in a format which allows consistency and the ability to be manipulated while analyzing project alternatives.

Fundamental questions associated with the development of a flood-threat recognition system address what warning times can be achieved, and how reliable the warnings will be. Answers to these questions depend on watershed and storm characteristics, and the flood-threat recognition method being considered. The tradeoff between warning time (the time from the first indication of precipitation to the time flooding begins) and warning reliability can be illustrated by considering a simple threshold-stage method of warning, in which a threshold stage at an index gage is to be used to trigger an alarm that warns of the impending exceedance of flood stage at a damage center. Illustrative data from the Central Great Plains Experimental Watershed in Nebraska showed that, when a warning is issued using an index location when a threshold discharge is exceeded, the choice of appropriate threshold discharge and associated warning time and reliability are important. The inverse relationship between warning reliability and warning occurrence was readily apparent. Key variables upon which warning time depends include: spatial variability of precipitation, temporal variability of precipitation, rainfall-runoff response characteristics of the watershed, and antecedent soil moisture conditions. Warning time for a specific historical storm event can be estimated using a rainfall-runoff forecast model for a number of historical events to determine the median value and variability of warning.

Two-dimensional fluidization experiments were performed on fine and medium coarse quartz sands at depths of 25.4 and 42 cm. Four supply pipes were used with orifice diameters of 1.587 mm (1/16 in), 3.175 mm (1/8 in), 4.76 mm (3/16 in), and 6.35 mm (1/4 in) spaced 5.08 cm (2 in) on centers. Hydraulic head in the bed, pressure in the supply pipe, flow rate, and geometry of the fluidized region were measured for prefluidization, initial, and complete fluidization, and for slurry removal. It was found that the flow rate needed to initially fluidize and fully fluidize a sand bed is directly proportional to increases in orifice size. The larger the sand size, the greater the flow rate necessary to initiate fluidization and the greater the flow rate necessary to fully fluidize the bed. A significant increase in flow rate is necessary to transform a bed from an initially fluidized state to a fully fluidized state. Internal pipe pressure in the fluidization pipe is inversely proportional to increases in orifice size. A drop in internal fluidization pipe pressure is experienced at the moment of initiation of fluidization. Ultimate trench width is inversely proportional to increases in orifice size. Since the submerged angle of repose of fine to medium diameter sand is relatively constant regardless of sand size or orifice size and since equilibrium is reached when all particles achieve the angle of repose, burial depth is the most important factor in determining ultimate trench top width. It was concluded that orifice sizes 3.175 mm to 4.76 mm should be used for most applications.

Twenty-one precipitation gage stations were selected in the Scioto River Basin (Ohio) for the study of regionalization. The kriging method used for the regionalization study was based on the linear minimum unbiased estimation. Truncation levels were calculated and listed along with their monthly means and record lengths. It was seen that the truncated values decreased as their corresponding levels increased, which implied an increase of drought severity. Based on the 21 truncated values at each severity level of precipitation drought, the kriging method was applied to obtain a regional distribution to determine the degree of water availability in the region. Contour lines for each truncation level were constructed to show possible drought distributions in the region. It was seen that the upper region of the basin tended to have lower values of water availability. As the truncation level increased the distribution became more disperse, represented by the gradual decrease in the contour gradients, and indicating that the problem of water availability became more regional when the level of drought severity increased. The estimation errors associated with each contour map were reasonably small; thus, it was concluded that the kriging estimations of precipitation drought severity were reasonably acceptable.

For computing the basinwide annual yields and single event sediment production for ephemeral channels previous reports and publications, USDA reservoir sedimentation survey data analysis, sediment yield maps for the western US, average annual sediment yield estimated from computations of total event sediment volumes for single events, flow duration and sediment load curve integration, estimated basin-wide sediment yield for the entire watershed, and the Dendy and Bolton Regional Analysis Method for sediment yield were used. The morphology of the Caliente Creek drainage basin and the nature of the sediments delivered to the channels and the potential for sediment storage within the drainage basin are controlled by the basin geology. Sediment transport in the basin is episodic and is governed by the occurrence of large runoff events. The approximate annual sediment yield at the Sivert Reservoir is 0.75 AF/sq mile/year. Single event floods can produce significantly more sediment per event than the annual sediment yield would indicate.

The ultimate purpose of the hydrologic modeling program is to develop an operational model for the Caernarvon Freshwater Diversion Structure, which will discharge up to 280 cu m/s from the Mississippi River to the estuary to control saltwater intrusion. The microcomputer-based model will use a diversion discharge algorithm and a dynamic programming routine to optimally apply time series of past, present and predicted future values of hydrometeorologic data to salinity time series to determine the diversion rates and gate settings required to achieve target salinity levels in the historically productive oyster reef zone. If operated properly, the diversion structure should be able to reduce salinity to the desired target levels during the biologically important spring and summer months in nine of ten years on the average. A strategy has been developed that will result in a model that can be applied to weekly and daily time series of salinity and its predictor variables to reliably forecast horizon of up to five weeks with weekly updates. The diversion project is scheduled to be operational by December 1990. The four-year post-construction monitoring program will allow for continuing model refinement through the analysis of observed salinity levels in comparison to predicted salinity. The estuary and watershed is also being numerically modeled to simulate the hydrodynamic and constituent transport processes for time scales of one day to six months or more for pre-project and post-project conditions.

Today, over 90% of the wetlands have been lost, primarily due to drainage for agricultural purposes. With an increasing interest in the restoration of wetland habitats, a need has arisen for prioritizing candidate wetland restoration sites, which would ensure expenditure of funds on the best available sites. A hydrologic model has been developed as a tool to assist in screening candidate wetland sites for restoration in the Rainwater Basin. The Wetland Hydrologic Analysis Model (WHAM) was developed to perform daily analysis of the hydrologic budget of individual wetland basins. Inflows to the wetland, which are input data for the WHAM, were derived with the Streamflow Synthesis and Reservoir Regulation model, which was developed by the North Pacific Division of the US Army Corps of Engineers. Statistical analysis was performed on the simulated hydrologic parameters including surface area, water surface elevation, storage volume, and average depth to evaluate the hydrologic effectiveness of the proposed restoration for each site. Priorities for acquisition and restoration can be assigned to the individual wetlands based on the results of these analyses.

Not only do the problems of accuracy, nonlinearity, and numerical stability need to be overcome, but also the computing efficiency and cost-effectiveness need to be addressed. A new 3-D finite element free surface flow model has been developed which utilizes the body-fitted coordinate transformation to approximate a highly-irregular solution domain by a finite element grid, which is used only for obtaining the global nodal numbers, their coordinates and connectivities. The global finite element equations are obtained by the application of a least square procedure to the residual of each of the governing differential equations within the working element. Several hybrid convective and nonconvective shape functions were developed. The adoption of Fourier components or trigonometric functions to construct quadratic Lagrangian shape functions allows realistic approximation of the viscous diffusion, which has also enhanced the accuracy and stability. The improved methodology was applied to simulate 3-D turbulent free surface flows around hydraulic structures. It was found that a 3-D case of a 27-node working element requires 108 coefficients in each global equation (rather than 500 as required in the traditional model), representing a significant savings in computing time. Results demonstrated that the newly-developed method is capable of producing accurate and reasonable simulation, eliminating spurious and node-to-node oscillation, and enhancing numerical stability and computing efficiency.

A blockage in Castle Creek produced Castle Lake. The characteristics of mudflow events resulting from the hypothetical breaching of this debris blockage dam were evaluated using a variety of lake levels and impounded water volumes for the initial breach conditions. A one-dimensional (Petrov-Galerkin finite element) unsteady mudflow routing model was used to simulate the movement of the dam-break-induced mudflow events downvalley through a Corps of Engineers' sediment retention structure (SRS) in five different hypothetical events. For existing conditions in the SRS, the maximum (lake full) mudflow hydrograph was reduced by 90% and the SRS was not overtopped. If the SRS was half full of sediment deposits when the maximum (lake full) mudflow occurred, the peak mudflow hydrograph was reduced by 80% and the SRS was not overtopped; however, the peak stage came within 10 feet of the top of the dam. If the SRS was initially filled with sediment to the crest elevation of the spillway, the dam would be overtopped for mudflow events if the assumed initial Castle Lake water elevation were higher than 2547 feet above sea level. The SRS would reduce flows in the downstream reaches of the North Fork Toutle River, even for a maximum mudflow event of the magnitude estimated. For existing conditions, the peak discharge into the downstream reach was reduced to 196,000 cfs and, for half-full conditions, to 266,000 cfs.

The new 'Marsh Elements' version of computer program RMA-2 was used throughout the study. It was found that the numerical model closely reproduced the circulation and water surface characteristics of the Kawainui Marsh for the April 4-9, 1989 storm events. The magnitude and phase of computed water surface profiles matched measured stage recording data quite well. The maximum computed water surface elevation in the levee ditch during the storm was 7.25 ft and occurred in the upstream-most section of the ditch. This is in the vicinity of the January 1988 storm overtopping of the levee. The extremely thick growths of marsh plants created large head losses in the flows through the marsh due to friction and physical obstruction. The high resistance to flows resulted in long travel times through the marsh and greatly affected the storage and hydraulic characteristics of the marsh as a flood control reservoir. Traditional level pool routing methods failed to reproduce the hydraulic characteristics of the marsh due to the irregular combination of thick growths of plants and open-water areas. During the April storm, timing of the inflow and outflow peaks were separated by 8 to 16 hrs, depending on the antecedent conditions (volume) in the marsh and the timing and amount of runoff associated with subsequent events. Tidal influences (+/-1.5 ft) were not important throughout the majority of the Kawainui Marsh. Tides influenced only the lower 1500-2000 ft of the levee ditch and the first 1000 ft of the marsh upstream from the outlet.

Bed material gradations and shear stress analyses indicated that particle motion was initiated at a minimum dimensionless critical shear stress of 0.01. Large boulders derived from glacial outwash deposits were immobile at the design flood event of 18,500 cfs. The frequency of mobilization of grains where 84% have similar diameter (D84 size) of the active riffles was related to the geomorphic characteristics of field-identified subreaches. Where the D84 grain size was mobile for over 50% of the time, bars were absent; where the D84 was mobile for about 35% of the time, in-phase bank-attached point bars were present. Where the D84 was mobile less than 5% of the time, the channel contained out-of-phase bank-attached and mid-channel bars. The corroboration of the shear stress analyses by the geomorphic evidence suggests that sediment transport modeling in steep and coarse grained rivers may have to utilize a lower value (0.01) of critical shear stress for initiation of bed material transport than is generally used (0.47).

Sediment sources for the 86-mi reach of the California coast between the Mexican Border and Dana Point include 20 major streams and 12 small groups of coastal streams. A peak discharge and volume frequency analysis of streamflow data collected within the study region was performed using the appropriate period of record corresponding to the present regulation condition for each gage; multiple linear regression analyses were performed on the data from the unregulated watersheds. Six of the major streams within the study region were judged to be watershed supply-controlled, two major streams within the study region were judged to be of indeterminate classification, and the remaining twelve major streams were determined to be transport capacity-controlled; each of the small groups of coastal streams was considered to be watershed supply-controlled. Estimation of the sediment yield for each of the supply-controlled watersheds was accomplished using the balanced hydrographs and the Modified Universal Soil Loss Equation, or an average annual sediment yield approach. The HEC-2 water surface profile computer model was employed to establish hydraulic parameters necessary for the sediment transport analysis. The results showed that the 20 major rivers contribute 90% of the average annual yield of sands and larger sizes to the California coastline. The remaining 10% is yielded from the small groups of coastal streams. The streams within the lagoon and marsh-intensive area contribute approximately 1% of the total sediment yield.

A 4-foot wide by 60-foot long rectangular flume was equipped with model bridge piers which were varied in length (1, 2, 4, and 8 feet), width (0.5 and 1 inch), and number (3, 4, and 5) to produce several configurations similar to prototype bridges in the Los Angeles District in California. A series of 'generic' model tests were carried out specifically to develop design relationships that could be used to predict the location of critical depth within the piers. The invert slope was varied to create supercritical flow having ratios of normal depth to critical depth of 0.8 and 0.9. It was found that the ratio of the distance between the upstream end of the pier and the location of critical depth within the piers to the critical depth ranged from 1.29 to 3.39. This distance appeared to be random with respect to the one-dimensional-based correlations which were investigated. However, one parameter which appeared to have some influence on the distance was the invert slope. Errors in the predicted values compared to measured values ranged from 2 to 55%. In cases where the existing pier length was relatively long (e.g. if the pier length was greater than the channel base width), the flow downstream of the critical depth control became subcritical within the piers presumably due to the friction losses produced by the long piers. In general, the short piers always produced supercritical flow downstream of the critical depth control, while the longer piers had flow regimes varying from supercritical to subcritical. The parameters which most significantly influenced the flow regime through the piers were the invert slope and the length of the piers.

To develop a plan to overcome those data gaps, an interagency team was formed. The team prepared a Plan of Study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), and one of the first anywhere in the nation, to identify and quantify impacts associated with commercial and recreational traffic. At this time, the POS represents a proposed course of action and has not been fully reviewed or approved. The POS consists of a series of 15 work units comprised of both laboratory and field studies which will take up to 10 years to complete. These studies will identify and quantify impacts to the following biological resources: adult fish, larval fish, freshwater mussels, aquatic macrophytes, macroinvertebrates, waterfowl, algae, side channels and backwaters. However, these biological impacts can generally be determined only if the hydraulic forces producing them--water velocity, pressure, direction of flow, waves and suspended sediment (potentially leading to sedimentation of side channels and backwaters)--are also measured and better understood. An interagency coordinating committee has been proposed to oversee the study process and to monitor study results annually. The results of these studies should be directly usable in current and future planning activities within the UMR and, to some extent, could be used to identify vessel-related physical and biological impacts throughout the nation's entire inland waterway system.

Data were collected to: (1) document the water quality characteristics of streams and impoundments in the Coteau area; (2) predict the impact of proposed impoundments; (3) define the amount of dissolved and suspended material transported; and (4) determine the differences in water quality between the impoundment inflows and outflows. Streamflow and water quality data were collected at 12 stream and four impoundment sites. Continuous record gages, set to collected data at 15- minute intervals, and readings taken by local observers wee used to complete discharge records at 10 stream sites and stage records at three impoundment sites. Automatic samplers and local observers collected storm runoff, sediment, and nutrient samples at 10 stream sites. Water quality samples were collected at various time and stage intervals during high flow and periodically during low flow. Primary emphasis in the stream- sampling program was on analysis of samples for nutrients in 1980-82, and on analysis of suspended sediment and nutrients in 1983-84. Field measurements were made of pH, water temperature, dissolved oxygen, specific conductance, alkalinity, and bacteria. Secondary emphasis was on analysis of major dissolved substances. Primary emphasis in the impoundments was on analysis of samples for phosphorus and chlorophyll and on the measurement of transparency. Temperature and dissolved-oxygen concentrations were measured to determine the degree of stratification. All data collected during the study are given in this report. The tables list mean-daily stream discharge, results of water quality analyses, and bed material particle-size analyses at stream sites. The tables also list information on pool stage, water temperature, and transparency, on dissolved-oxygen, chlorophyll a, phytoplankton, and nutrient concentrations, and on chemical and particle-size analyses of bed material at impoundment sites.

The Interior Highlands consist of hilly to mountainous terrain underlain by sandstone, shale, limestone, and dolomite. Significant water-yielding units within the Arkansas River basin in Arkansas include subsurface Paleozoic rocks such as the Eminence and Potosi Dolomites, the Gasconade Dolomite and the Van Buren Formation, and Roubidoux Formation as well as outcrops of Paleozoic rocks, the Sparta Sand, and Quaternary deposits. Groundwater withdrawals in the 15- county area approximating the study area totaled 257 million gallons per day in 1985. More than 70 percent of this total was withdrawn from the Sparta Sand and the Quaternary deposits in the Coastal Plain. Less than 10 percent was withdrawn from the Paleozoic units that underlie the Interior Highlands. The quality of groundwater withdrawn from the various aquifers in the study area generally is suitable for most uses. With the exception of the Sparta Sand, the major aquifers yield water that is commonly very hard and highly mineralized. Yields from the different water-bearing units are highly variable. Several of the subsurface Paleozoic formations yield as much as 450 gallons per minute, whereas outcrops of Paleozoic rocks rarely yield more than 10 gallons per minute. In the Coastal Plain, the Sparta Sand and the Quaternary deposits yield as much as 2,000 and 2,500 gallons per minute, respectively. In the northern part of the study area, the extensive fracturing of formation outcrops makes them more susceptible to contamination from the surface. Several studies have identified localized bacterial contamination of water from both wells and springs in this part of the study area. Nitrate concentrations exceeding U S Environmental Protection Agency primary drinking water standards have occurred in some areas. No areas within the study area met the critical-use criteria established by the Arkansas Soil and Water Conservation Commission. Potential groundwater problems include potential contamination from one Resource Conservation and Recovery Act site, two Comprehensive Environmental Response, Compensation, and Liability Act sites, and numerous landfills and surface impoundments.

Flow ratios, which were obtained by dividing subbasin flows of different truncation levels by their corresponding outlet flows, are calculated. The flow ratios of 17 selected subbasins decreased significantly with increasing truncation levels, whereas their mean-flow ratios were approximately equal to their corresponding area ratios. Therefore, the estimation of irrigation water using the drainage area ratio, which has been practiced in the studied river basin (Scioto River, Ohio), is impractical in case of droughts. Furthermore, assuming the time-dependent Poissonian behavior of drought series, the drought intensity function was developed to investigate drought severity in the basin. Based on plots of drought intensity function, the drought intensity has been increasing significantly for the basin investigated.

An investigation into appropriate scaling laws resulted in the conclusion that at model-to-prototype scales greater than 1:100, physical model studies can be reasonably scaled to prototype phenomena. Therefore, results from the model studies can be used to provide an increased understanding of the physical processes that occur during the open-water placement of dredged material.

This review concludes that the routine flow discharge rates for each project lake are adequate for present needs. However, some institutional aspects need updating. This report contains proposed changes to the low flow plan including: (1) interagency coordination procedure with specific triggers for stepped responses as conditions worsen, including identification of low flow emergency conditions in the Minneapolis-St. Paul metropolitan area; (2) organization of the St. Paul district in-house drought management team and (3) preparation and use of a public information plan specific to droughts. The relative priority for use of Federal project waters at the Headwaters project is commercial navigation first. Treat Trust resources second, and general public good third. It is expected that emergency conditions that would justify releases in excess of the routine low flow plan to be rare. This report describes the decision-making and coordination process that would be followed by the St. Paul District, Corps of Engineers in the unlikely event that emergency supplemental flows might be needed from the Headwaters lakes project.

The study area is located on the right descending bankline at the north bridge abutment, in sec. 2, T. 72 N., R. 18 W., Guilford Township. A study was initiated on Apr 12, 1989, to provide assistance to Monroe County for protecting the north bridge abutment from further damages due to the eroding bankline. This Definite Project Report recommends that riprap be placed along approximately 350 linear feet of the bankline at the north bridge abutment. It also recommends that a farm drainage ditch on the upstream side of the abutment be straightened and riprapped to divert the drainage from the bridge abutment and piers.

The quality, extent, and diversity of this area's wetland habitat is rapidly decreasing. The migratory waterfowl and other wetland species which currently depend upon and utilize this habitat type for resting and feeding, as well as reproduction and brooding, are being adversely affected by its declining availability. Pool 22 and its environs currently lack sufficient wetland habitat to maintain the levels of waterfowl, shorebird, and furbearer use previously experienced in this area. Prior to establishment of the extensive system of agricultural drainage districts adjacent to this pool, prime forested wetlands were readily available throughout the area during annual migrations.

Flow diagrams of the pilot-scale unit for tertiary nitrification with optional pre-filtration and of the full-scale 2-stage RBC plant for BOD removal, nitrification, and intermediate filtration are included. The studies showed that nitrification in single-stage RBC systems could be considerably enhanced by introducing sedimentation and/or filtration at the point in the system where degradation of organic matter was substantially complete. In addition, reversal of flow provided a further increase in nitrification capacity. The advantages of tertiary RBC systems over tertiary biological filters for nitrification of effluents are indicated.

In the new technique, layers of fresh carbon were added to the top of existing layers when the determined level of a contaminant being removed was exceeded, until such time as the available bed depth was filled. The method lengthened the carbon life in terms of adsorption of volatile organics by reducing the time available to dissolved organics to occupy adsorption sites on the carbon. The experimental work described assessed alternative modes for the removal of the volatile organics trichloroethene and tetrachloroethene from a Swiss spring water which had been pre-treated by flocculation, filtration and ozonation. Different types of carbon were evaluated in parallel studies on upflow layered beds, with one fixed-bed filter being operated in upflow mode at the same velocity as the layered filters, and another fixed-bed filter being operated in downflow mode at two thirds this velocity. Data on the initial bed depth, and of the top-up layers, are given, before details of the time to breakthrough of the volatiles in the different filters, and of the proportion of each volatile in the effluents sampled at various bed depths within the initial and added layers. From these, estimates were made of the performance of each bed type for a given bed depth in terms of time to contaminant breakthrough. The layered upflow beds showed an improvement of approximately 50 per cent in terms of time of operation and throughput per unit volume of carbon used by comparison with the fixed-bed filter operator at the same hydraulic loading irrespective of the type of carbon used. The downflow fixed-bed filter, which was operated over a longer time than the others, gave greater throughput, due to the lower average influent concentrations found over the longer period. Modifications to the purely empirical depth of the layers added in the experimental rig would be incorporated in a full-scale carbon filter to be built into the treatment works for the Swiss city of Porrentruy, where operational experience would be world pioneering.

N1 - Last updated - 2011-12-12 ER - TY - JOUR T1 - Switzerland seeks small solutions to rural pollution AN - 13747541; 199003642 AB - A survey of the provision of small-scale, rural sewage treatment facilities in Switzerland is presented, with more detailed data for the canton of Grisons, which was used as a representative sample area to gain an insight into future national requirements for sanitation. Of the 900 Swiss sewage works, about a third served population equivalents of between 100 and 1000; sewage works serving less than 100 did not appear in the national archive. Their effluent volumes accounted for only 2 per cent of the national total. The Grisons investigation revealed that, of 168 sewage works, 127 served the 100-1000 population equivalent range, and that of the additional 82 deemed to be necessary 71 would serve that range. Nationally, activated sludge was the preferred treatment for the large-population sewage works, with biofilm methods (trickling filter or rotating biological contactor) dominating the smaller population picture. Future developments were likely to relate sewage works' performance more closely with the requirements of the receiving water. A more intense network of local treatments, rather than conveyance by sewer to distant large-scale sewage works, was envisaged, flows to such small sewage works being facilitated by the greater use of separate sewerage systems and flow-equalization techniques.

The plant operated with a shorter sludge age in winter than in summer, and was only partly nitrifying in winter. Up to 97 per cent of NTA was biodegraded in both seasons, but no removal of EDTA was observed. Following a shock load of NTA in winter, the daily average degradation of NTA increased 4-fold. The increased NTA concentration caused remobilization of zinc and lead from the activated sludge and an increase in the concentration of these metals in the effluent, but there was no increase in the effluent content of copper.

Survey methods used to obtain stream cross-sectional geometry were field surveys, aerial spot elevation surveys, and the use of topographic maps. These gave rise to different types of errors. Errors in estimating Manning hydraulic roughness values also affected the accuracy of steady-flow water surface profiles. A range of errors in computed steady flow profiles was derived, using a Monte Carlo simulation strategy. Regression equations relating survey methods and their associated accuracy levels and the reliability of hydraulic roughness values to estimated profile errors were developed.

AN - 36403645; 2453 AB - PURPOSE: Widening and realignment of 22 miles of U.S. Highway 189 between its junctions with Utah Route 52 and U.S. Highway 40 in Utah and Wasatch counties, Utah are proposed. This final supplement to the final environmental impact statement of September 1979 addresses some of the improvements to roads between the junction of Utah Route 52 with Interstate 15 (I-15) in Orem on the west and the intersection of U.S. 189 with U.S. Highway 40 approximately 0.5 mile south of Heber City on the east. A 5-mile section of the 25-mile overall route, from the western terminus to the Murdock Diversion in Provo Canyon, has been improved to a 4-lane facility. The preferred alternative would have two lanes in each direction, divided by a median, with minimum pavement and clear zone widths and a separate recreation path. POSITIVE IMPACTS: Proposed roadway improvements would enhance the capacity and safety of the highway while maintaining the recreational and aesthetic qualities of the canyon. Road realignment would correct substandard geometry to meet current design criteria. Access to developed recreation facilities in Provo Canyon and Heber Valley would be improved significantly, and turnouts would be provided for use by sightseers. NEGATIVE IMPACTS: Rights-of-way requirements would displace 227 acres of land, involving displacement of one housing unit. A total of 29 receptors would sustain noise impacts, and 227 acres of terrestrial habitat would be impacted. Although 21 acres of wetlands would be impacted by the project, all of this habitat would be replaced at other sites. A total of 183 acres of terrestrial habitat would also be replaced. Approximately 1,530 feet of Provo River would require relocation, and the river would be affected by five river crossings. One archaeological site, two historic sites, and two miles of historic railroad tracks that are eligible for inclusion in the National Register of Historic Places would be affected. Two public parks and one recreation area would also be affected by the project.

AN - 36406073; 2463 AB - PURPOSE: Alternatives to the operation and regulation of Lake Red Rock in Marion County, Iowa are being considered. The current operation plan requires that the lake be raised at intervals to compensate for sedimentation and to maintain the 50,000 acre-feet of water originally approved for the reservoir. This second draft supplement to the final environmental impact statement (EIS) of August 1976 addresses the impacts of raising the permanent conservation pool at Lake Red Rock from elevation 734 National Geodetic Vertical Datum (NGVD) to 742 feet NGVD. Elevation 742 NGVD represents the conservation pool necessary to store 100 years of sediment accumulation, as well as the volume of water required to provide reliable low-flow augmentation to downstream river reaches during severe drought conditions. The conservation pool was raised from elevation 728 NGVD to elevation 734 NGVD in November 1988 as a result of recommendations in the Lake Red Rock Water Control Plan issued in May 1988. Since that time, the state of Iowa has requested that the conservation pool at the lake be raised to the 100-year design level of 742 NGVD. This supplemental EIS describes the environmental, cultural, economic, and social impacts of a 742 pool raise and includes a Water Control Plan that addresses the water control aspects of a conservation pool raise to elevation 742 feet NGVD and a Supplemental Master Plan that describes the details of impacts to federal facilities and planned facility relocations. Based on the information, the Rock Island District recommends a permanent conservation pool elevation of 742 feet NGVD, with a yearly fall raise to elevation 744 NGVD for the benefit of migrating waterfowl. POSITIVE IMPACTS: The recreation experience at the lake would be enhanced by improving aesthetics, boating, fishing, and wildlife habitat, and part of the recreational needs of south-central Iowa would be fulfilled. Residential property values could increase slightly. The increased potential for recreation visitors to the lake could attract new businesses to the area and create new employment opportunities. NEGATIVE IMPACTS: Construction machinery would generate a temporary increase in noise during scheduled relocation of facilities, creating a minor, short-term disturbance to recreationists at the lake. Recreation at various facilities would be temporarily disrupted during the construction phase. The values of farm properties could be adversely impacted. An increased risk of flooding, resulting from any raise in pool elevation, is perceived by area farmers. LEGAL MANDATES: Water Resources Development Act of 1976 (42 U.S.C. 1962d et seq.).

AN - 36402137; 2460 AB - PURPOSE: Alternative methods for disposal of material dredged from the Long Island Sound region of New York are discussed. This draft supplement to the final environmental impact statement (EIS) of June 1982 provides additional court-ordered information. The final EIS, which proposed open-water disposal in the western portion of Long Island Sound, was declared deficient by the Eastern District Court of New York in ""Town of Huntington et al. versus Marsh.'' To correct the specific deficiencies cited by the court, the draft supplemental EIS includes discussions of the Ocean Dumping Act criteria and the types, quantities, and cumulative effects of dredged material disposal at the Western Long Island Sound (WLIS) dredged material disposal site. Approximately 990,000 cubic yards of dredged material has been disposed at the WLIS site. Most of the material is composed of silts and clays, with some sand. The material has been dredged from harbors in Connecticut and New York. The weighted average of contaminants in the material at the WLIS site is generally similar to the ambient sediments at the disposal site and reference stations. It is expected that dredged material of similar composition would be deposited at the site in the future. Data collected under the Disposal Area Monitoring System (DAMOS) has indicated that the benthic community returns to ambient conditions shortly after disposal of dredged material is completed. POSITIVE IMPACTS: Site designation would allow for dredging of new channels and maintenance of existing channels in the Long Island Sound and its vicinity. Hence, recreational, economic, and defense benefits provided by the waterways would be perpetuated. NEGATIVE IMPACTS: General impacts associated with disposal operations would include temporary turbidity in the immediate area of disposal and an associated, short-term reduction in dissolved oxygen levels and releases of contaminants into the water column. Mixing and dilution by water at the disposal site would reduce these impacts on water quality to a negligible level. The displacement of contaminated harbor sediments could increase the contaminant level of the sediments at the disposal site. Discharge of dredged material would bury a small number of benthic organisms, demersal fish, and lobsters within the immediate discharge area. Cumulative effects of disposal would include a change in the bottom topography at WLIS and a change in sediment composition.

Preparation date: December 21, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - JACKSON HOLE, WYOMING FLOOD PROTECTION PROJECT: SNAKE-GROS VENTRE RIVERS LEVEE MAINTENANCE. AN - 36399811; 2470 AB - PURPOSE: Operation and maintenance of the flood control levees protecting Jackson Hole, Wyoming are assessed. The study area includes both the federal and nonfederal levees on the banks of the Upper Snake River and lower reach of the Gros Ventre River. All levees on the Snake River from Grand Teton National Park to the South Park Bridge would be maintained, along with three nonfederal levees located on the lower reach of the Gros Ventre River. The scope of this document is limited to the continuation of historic operation and maintenance practices, with minor modifications in material (revetment) supply practices. Teton County and the state of Wyoming have provided some annual maintenance of the levee system from Grand Teton National Park to the South Park Bridge. Under the proposed Corps of Engineers plan, maintenance activities would include removal of snow from the tops of the levees in early April to allow access for patrolling and flood fighting, conducting emergency repairs when high flows damage the levees and threaten levee failure, rock quarrying and stockpiling operations to obtain levee materials, removing perennial vegetation from levees, removing and burning snags that might damage the levees, and maintaining culverts and roads providing access to the levees. Teton County would retain responsibility for patrolling the levees from the beginning of the high-flow period (10,000 to 12,000 cubic feet per second) until the flood peak subsides to that level. Due to the limited quantity of appropriate materials in the existing quarry, quarry sites in the vicinity of Curtis Canyon, Flat Creek, Teton Pass, and Phillips Ridge are being investigated. POSITIVE IMPACTS: Flooding in the two affected rivers, generally caused by spring snowmelt, would be controlled by the maintained system. Development within the floodplain would be protected and allowed to continue. Planned and scheduled maintenance on a nonemergency basis, accompanied by rehabilitation of the levee sections in need of repair, would presumably produce long-term savings through decreased emergency expenditures. It is expected that integrated management of the levees as a single project would result in greater long-term river channel stability and increased ability to investigate and respond to physical changes within the system. NEGATIVE IMPACTS: Continued maintenance of the levees would have direct and indirect influences on the river channel, aquatic habitat, riparian areas, wildlife habitat, and floodplain development.

Preparation date: December 11, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WASTEWATER TREATMENT FACILITIES FOR THE CITY OF NEW BEDFORD, MASSACHUSETTS. AN - 36404788; 2459 AB - PURPOSE: Construction and operation of a secondary wastewater treatment plant to serve the New Bedford area of Massachusetts are proposed. Existing wastewater collection facilities in New Bedford include more than 200 miles of sewers combining wastewater and stormwater (combined sewers) in the south and central parts of the city and in portions of the towns of Dartmouth and Acushnet. The primary wastewater treatment plant is no longer in compliance with federal treatment plant standards. Currently, effluent from the plant is discharged through an outfall into Buzzards Bay. Under the recommended plan, treatment facilities would include a catenary bar screen and aerated grit chamber for preliminary treatment, a rectangular clarifier for primary treatment, an air activated sludge system and an anaerobic selector and rectangular clarifier for secondary treatment, and disinfection via sodium hypochlorite followed by dechlorination. Two treatment plant sites, namely, Fort Rodman and Standard Times Field, continue to be under consideration. Chemically fixed sludge would be disposed at Crapo Hill Landfill; additional chemically fixed or lime-stabilized sludge would be disposed at a site adjacent to the New Bedford municipal golf course and/or an existing solid waste landfill and at a site near the Polaroid facility and Acushnet Cedar Swamp. In addition to chemical fixation, incineration and composting methods would be used to deal with solids. Installation of the outfall would involve the construction of a tunnel to a site identified as the ""301(h) site'' and the addition of a seabed diffuser at its terminus. The outfall site would be located 22,200 feet south of Clarks Point, south-southwest of Negro Ledge, at a depth of 45 feet at mean low water. POSITIVE IMPACTS: Operation of the new plant would bring the wastewater treatment facilities serving New Bedford into compliance with federal standards. Facilities that have had a history of problems and malfunctions would be replaced by modern, effective facilities. NEGATIVE IMPACTS: Construction activities would create fugitive dust and noise and increase traffic in the vicinity of the treatment plant site and landfills. Some wetlands would be filled at either of the candidate treatment plant sites, and development of the plant at either site would conflict somewhat with or displace existing and contiguous land uses. Siting of the plant at Fort Rodman would require protection against flood hazards affecting the site and would involve encroachment into the Fort Taber Historical District and several historic structures outside the district. Selection of the Fort Rodman site would also result in significant visual impacts; either site would affect current recreational uses in the area of the chosen site. Some air quality and odor problems would be associated with operation of the plant. Archaeological artifacts, artifacts from the War of 1812, and a Nineteenth Century candle factory could be affected by construction and operation activities at the Standard Times Field site, and significant archaeological resources could be affected at two of the landfill sites. Outfall construction would result in water quality degradation and disruption of benthic habitat; polychlorinated biphenyls (PCBs) and other contaminants would be dispersed into the water column during dredging. The presence of shipwrecks in the vicinity of the outfall tunnel would involve the potential for impacts to historically significant resources. Effluent discharge would increase levels of trace metals, PCBs, and organic carbons, affecting sediment and water quality; water quality standards would be exceeded for some chemicals, including chlorine.

Preparation date: December 8, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ISSUANCE OF A NEW SOURCE NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM PERMIT TO CF MINING CORPORATION, HARDEE PHOSPHATE COMPLEX II, HARDEE COUNTY, FLORIDA. AN - 36390982; 2419 AB - PURPOSE: Issuance of a new source national pollutant discharge elimination system permit for the development and operation of an open-pit phosphate mine and beneficiation plant on a 14,994-acre site in Hardee County, Florida is proposed. Mining activities would encompass 14,647 acres, all of which would have to be reclaimed, and would produce 94 million tons of phosphate products over a 27-year period. The mine operation would produce approximately 2.0 million tons per year of wet phosphate rock for the first 7 years of mining and 4.0 million tons per year during the following 20 years. During mining, all of the rock mined from the project would be shipped to fertilizer plants for conversion to finished fertilizer, with 100 percent of the tonnage going to existing fertilizer manufacturing facilities at Plant City and Bartow. To accomplish these operational objectives, a beneficiation plant and temporary rock storage facility would also be constructed on the site. The initial phase of the action would involve land clearing and open burning of cleared debris. The cleared acreage in front of the mining operation would average approximately 80 acres. The mining operation would use a single 55-cubic-yard dragline, supplemented with a second similar dragline, beginning in the eighth year of mining. The mined matrix would be slurried and transported via pipeline to the beneficiation plant for washing. An access railroad spur would be constructed to link the plant with the Seaboard Systems Railroad that presently bisects the property. Waste disposal would be via sand/clay mixing. Approximately 100 million gallons of water would be used per day to support mining and beneficiation; 93.5 million gallons per day would be supplied from a recirculation system and 7.85 million gallons per day would be removed from groundwater sources. The reclamation plan would be based on the use of waste sand and clay mix material as backfill over most of the mined area; the plan would return the mined land to uses compatible with surrounding area uses, which are primarily agricultural. POSITIVE IMPACTS: The new operation would allow the permit applicant to maintain a continuous supply of phosphate fertilizer for its cooperative member organization. The phosphate rock resulting from this initial expansion would be used to replace existing rock supply contracts. In addition to contributing to the nation's supply of fertilizer, the project would boost the local and regional economy. Reclamation activities would increase the acreage of improved pastureland, forested uplands, freshwater marsh, freshwater swamp, and lakes. NEGATIVE IMPACTS: Mining would reduce the acreage of palmetto prairie, field and row crops, and citrus orchards, even after reclamation. The geological and soil composition of the site would be altered significantly. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: December 4, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SITING OF WASTEWATER TREATMENT FACILITIES IN BOSTON HARBOR, MASSACHUSETTS: LONG-TERM RESIDUALS MANAGEMENT FOR METROPOLITAN BOSTON (FINAL SUPPLEMENT III TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1985). AN - 36383368; 2458 AB - PURPOSE: Upgrading of the Metropolitan District Commission (MDC) wastewater management systems, including sewer interceptors, wastewater treatment facilities, and sludge disposal facilities, in Boston, Massachusetts is proposed. The final environmental impact statement (EIS) of December 1985 recommended treatment of wastewaters from the entire Metropolitan Sewerage District service area at a centralized location at the Deer Island Plant. This final supplement to the final EIS on the upgrading project addresses the clean-up of Boston Harbor. More specifically, the document addresses the long-term (1995-2020) treatment, transport, and disposal of ""residuals'' from the new Massachusetts Water Resources Authority (MWRA) wastewater treatment system. Residuals include grit, defined as heavy particles settling from the wastewater stream; screenings, defined as large objects screened from the wastewater; scum, defined as floating material skimmed from the surface of the wastewater; and sludge, defined as solids settling from the wastewater during treatment. Six sites and six techniques of disposal are considered. The MWRA Board has chosen, as its recommended plan, a combination of dewatering and heat-drying of residual sludge at the Quincy Fore River Staging Area and placing results at the Walpole-MCI site. Quincy has a population of approximately 85,000 and lies approximately 10 miles south of Boston. The MWRA has also finalized its decision to use solid bowl centrifuges, rather than belt filter presses, as the primary dewatering device for the long-term residuals management period. Combined leachate and sanitary wastewater from the landfill facility would be discharged to the Walpole municipal sewer system via a 9,000-foot force main (two to four inches in diameter) from an on-site pump station along Winter Street and Route 1A north to an existing 10-inch-diameter sewer in the Walpole system; the average daily discharge would be approximately 15,000 gallons. POSITIVE IMPACTS: The Quincy site would offer an environmentally acceptable means for transfer, dewatering, and heat drying of residuals. Placement of dried residuals at the Walpole site would prevent odor, traffic, and land use problems associated with composting at the Quincy site; the latter composting site was proposed in the draft supplemental EIS, but all composting has been eliminated in the final EIS. NEGATIVE IMPACTS: Noise impacts would result from residuals processing and handling at the sites; these noise impacts would be minimal at the heat-drying and off-loading facilities due to the distance of the facilities from receptors. Truck traffic would increase in the Quincy and Walpole areas, and the traffic could overlap truck traffic generated by the Deer Island treatment plant. Developments at the Quincy site would result in damage to a district eligible for inclusion on the National Register of Historic Places.

Operational and procedural problems encountered in determining how a sediment- associated contaminant affects aquatic organisms cause additional complications. If sediment quality criteria (SQC) are to be used to regulate dredged material disposal, prediction of biological responses based on changes in sediment geochemistry, i.e., sediment physical and chemical properties, and sediment contaminant levels must be possible. Radioactive tracers can be used to evaluate the effects of changing concentrations of sediment contaminants on aquatic organisms if the assumption can be made that the contaminant does not degrade during the study. Spiking a sediment with contaminants has generally been accomplished by the addition of organic solvent carriers containing the contaminant to the soil or sediment.

J. roemerianus was found to be composed of genetically distinct populations using reciprocal transplant studies and common environment experiments. The soil water salinity of tidal marshes is the selective force at work. Adaptation is through natural selection for high salinity tolerance. Morphological adaptation has resulted in dwarf plants , with very short mature leaves (average 66 cm), occurring on hypersaline salt flats (35 to 65 ppt seasalts). Under a less saline regime (15 to 45 ppt seasalts), mature plant leaves were moderate in length (average 122 cm) and plants growing under a very low salinity regime (3 to 10 ppt seasalts) had the longest leaves (average 215 cm) reported for the species. Three populations of J. roemerianus were used in this study. Reciprocal transplant studies showed that plants from habitats of higher salinity could be successfully transplanted into habitats of lower soil water salinity, but not form lower to higher salinity areas, indicating that salt tolerance and adaptation is important to survival. Plants from the three populations were grown in a common environment experiment for 3 years with relatively high applications of nitrogen, phosphorus and potassium fertilizer. Although the leaves of dwarf plants doubled in length during the second year of the experiment, they did not increase further during the third year. Leaf length was significantly different among the three populations. Soil water salinity is the selective force causing genetic differentiation in J. roemerianus.

AN - 36399940; 2456 AB - PURPOSE: Construction of a 16.1- to 16.7-mile State Trunk Highway (STH) 29 bypass around the village of Bonduel and city of Shawano in Shawano County, Wisconsin is proposed. The 1989 traffic volume on the existing 15.4-mile route was 10,300 vehicles per day (vpd), and this figure is projected to increase to 11,900 vpd by 2014. Respective traffic figures for these years in Shawano are 13,900 to 16,800 vpd and 15,250 to 25,250 vpd. In addition to the option of improving the existing through route, two southern and one northern bypass alternatives are under consideration. Improvement of the existing through route would involve construction of a four-lane curb-and-gutter section. The bypass project would consist of a four-lane controlled-access facility, with two 12-foot driving lanes in each direction, 6-foot inside and 10-foot outside shoulders, ditch sections on either side, and a 60-foot grass median. The project would begin on STH 29 approximately 1.5 miles east of Bonduel and would rejoin existing STH 29 approximately 0.5 mile west of Thornton. All build alternatives would require a new crossing of the Wolf River. A bypass to the south of Bonduel would require a crossing of the Shioc River. The north bypass would also require a crossing of the Shawano Lake Outlet and could require interchanges at Highway 47/55 south of Bonduel, at the intersection of Highway 22/29 east of Shawano, and at Highway 47/55 north of Shawano. One southern bypass could require interchanges at Highway 47/55 south of Bonduel, near the intersection of Highway ""B'' and Highway ""T,'' at Pit Road, and at Highway ""MM.'' The far southern bypass would require interchanges at Highway 47/55, at Highway ""T,'' and at Highway 22. The estimated cost for improving the existing facility is $12.3 million, while costs of the bypass alternatives are estimated at $30.5 million to $40.4 million. Benefit-cost ratios for the bypass alternatives range from 2.7 to 3.3. POSITIVE IMPACTS: Bypass availability would separate through traffic, including numerous large trucks that make up 40 percent of STH 29 traffic, from local traffic within Shawano, easing local congestion and reducing long-distance travel times. Projected traffic capacity and safety problems would be forestalled. The bypass would route 80 percent of through traffic around Bonduel and 40 to 64 percent around Shawano in 2014. The bypass would constitute a portion of a multilane route along STH 29 that would ultimately cross the entire state. NEGATIVE IMPACTS: Improvement of the existing facility would require the acquisition of 138 acres, including 101 acres of farmland within 25 farms and 10 acres of wetland, and displace 14 residences and 18 businesses. Traffic noise on the improved through route would exceed federal standards at 93 residential receptors. Construction of a northern or southern bypass would require the acquisition of 488 to 506 acres, including 306 to 351 acres of farmland, impacting 37 to 44 farms; the conversion of 49 to 72 acres of wetland; and the displacement of 17 to 20 residences, 2 to 3 farms and, possibly, 1 business. Bypass alternatives would result in potential disturbance at 20 to 45 archaeological sites.

Preparation date: November 28, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OPERATIONS, MAINTENANCE, AND MINOR IMPROVEMENTS OF THE FEDERAL FACILITIES AT SAULT STE. MARIE, MICHIGAN (FINAL SUPPLEMENT II TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1977). AN - 36391089; 2466 AB - PURPOSE: Extension of operations of the locks at Sault Ste. Marie, Michigan to as late as January 31 (with a possible additional extension through February 14) is proposed to allow additional vessel transits in response to the reasonable demands of commerce. Currently, operations are terminated after January 8 (with a possible extension to January 15). This second final supplement to the final environmental impact statement (EIS) of July 1977 addresses a proposed change in the plan of operation of the federal facilities at Sault Ste. Marie. Specifically, it addresses potential environmental impacts due to the proposed extension of annual operations. The supplement also contains additional information not incorporated into the original final EIS or the first supplement addressing the extension of lock operations to January 8 (with a possible extension to January 15). Environmental studies were conducted to evaluate potential adverse impacts of the extension. These studies focused on the upper Great Lakes connecting channels, namely, the St. Marys River, the St. Clair River, Lake St. Clair, and the Detroit River. It had been determined from previous studies that it was in these channels that navigation under winter conditions would be most likely to have adverse impacts. Due to concerns about unforeseen, possibly cumulative adverse effects from vessel passage during periods of ice formation, considerable effort was put forth to obtain all necessary descriptive and analytic information to evaluate the potential effects. In addition to studies on current resources, a historical study of wetland resources was completed; a mathematical model was created for evaluating vessel effects under ice conditions; an oil and hazardous materials spill model was created for analysis of potential impacts; and risk analyses were conducted for oil and hazardous material spills. POSITIVE IMPACTS: Extension of lock operations would benefit industry and commercial navigation by allowing for greater use of low-cost waterborne transportation to and from Lake Superior ports and reducing winter stockpiling costs. Industrial and commercial shipping concerns could take advantage of up to a month of additional shipping time for vessel traffic passing through the Sault Locks. NEGATIVE IMPACTS: Deer on Neebish and Sugar islands could be adversely affected during years in which traffic levels through the locks were significantly increased over normal traffic levels. High traffic levels could result in blockage of deer attempting to cross the shipping channel to Neebish Island in early January. Some Neebish Island deer could be isolated from browse on St. Joseph Island. Benthic communities, water quality, and submerged aquatic plants could be affected within a short reach of the St. Marys River. Some shore structures located near the navigation channel could be subjected to increased winter damage.

AN - 36409249; 2465 AB - PURPOSE: Implementation of flood control measures for the 418-square-mile Aloha-Rigolette drainage basin located on the left descending bank of the Red River in Louisiana is proposed. The flood control area lies in Winn, Grant, and Rapides parishes. This final environmental impact statement provides a more detailed segregation and evaluation of the project drainage basin. Of the 22 initially considered plans, 3 were identified for final consideration. The tentatively selected plan would involve construction of three 10-foot by 10-foot culverts, with floodgates, placed at the mouth of Bayou Darrow to reconnect it to the Red River; clearing and snagging 7.6 miles of Bayou Darrow; construction of a closure on the existing Saline Bayou diversion canal; and construction of a closure and low-flow structure on Bayou Rigolette just below its junction with Bayou Darrow. The project would discharge water from the Du Grappe and Darrow reaches into the Red River at a point upstream of the existing discharge and at an increased rate, lowering flood stages in the more critical lower Rigolette reach. To offset the terrestrial habitat losses resulting from construction activities and flood control, the plan would include the purchase of 208 acres of agricultural lands; construction of a rock weir on Bayou Rigolette above U.S. Highway 71; and acquisition of a flowage easement on 100 acres of woodlands and 30 acres of agricultural fields. Lands to be purchased would be those that lie between the Iatt Lake weir and Highway 71; management of these lands would facilitate drawdown of Iatt Lake, enhance lake fishery resources, and allow flooding on the mitigation lands to benefit overwintering waterfowl. The estimated first cost of the project is $7.97 million, and annual charges are estimated at $859,000. The benefit-cost ratio is estimated at 1.17. POSITIVE IMPACTS: The project would reduce flooding in the agricultural area and create conditions favorable to intensified agricultural uses. The purchase of flowage easements would improve fishery resources. Annual benefits redounding from the plan would be valued at $1.0 million. NEGATIVE IMPACTS: Construction activities would alter 98 acres of open water habitat in Bayou Darrow and 194 acres of terrestrial riparian habitat along the bayou. In addition, 12 acres of bottomland hardwoods would be impacted due to floodgate construction and 18 acres of riparian habitat would be impacted due to the construction of two canal closures. The Bayou Darrow sport fishery would be reduced from 50 to 5 pounds per acre, and suitable overwintering waterfowl habitat would decline by 29,750 acre-days of flooding.

Preparation date: November 8, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOCAL FLOOD PROTECTION, PETERSBURG, GRANT COUNTY, WEST VIRGINIA. AN - 36402261; 2469 AB - PURPOSE: Implementation of a flood control plan for North Petersburg, South Petersburg, and the Grant County Airport Industrial Park, West Virginia is proposed. The entire study area lies within eastern Grant County. Petersburg covers approximately 0.7 square mile and straddles the South Branch Potomac River. The recommended plan would include 18,850 feet of earthen levee, 1,090 feet of floodwall, 35,430 cubic yards of channel excavation near the Main Street bridge, bridge replacement/modification, environmental mitigation, and appurtenant project features, such as ramps, closures, riprap, relocations, and ponding areas for local drainage. Environmental mitigation features associated with the plan would include off-project land acquisition and planting of high-quality vegetation; a total of 25 acres of fruiting trees and shrubs would be planted, providing 100 percent mitigation for impact to categories 3 and 4 habitat. To address the short flood warning time for this section of the South Branch, a flood warning system, built on the existing IFLOWS system, would be implemented. The estimated first cost of the plan, including future price escalation through project completion, is $18.0 million. Average annual costs are estimated at $1.7 million, and the benefit-cost ratio is estimated at 1.26. Significant cost savings could be realized for the recommended plan if detailed engineering analyses of the bridge reveal that replacement at the 100-year design flood level is not required. The preconstruction engineering and design phase would be implemented over 30 months. Construction of the project would require 24 to 30 months. POSITIVE IMPACTS: Project implementation would provide for protection against the 100-year flood, preventing losses to property and health and safety hazards within the flood control area. The project would provide annual flood control and other benefits worth $2.15 million, for a net annual benefit of $441,000. Provision of flood protection would probably attract additional business to the Petersburg area. NEGATIVE IMPACTS: A total of 47.5 habitat units of upland habitat would be destroyed by the project. Levee construction would permanently displace approximately 26 acres of land, consisting primarily of abandoned farmland, cultivated fields, pastures, and urban land. Project structures would block the view of the river from some locations. Houses and mobile homes along the new levee would be displaced, and two potentially significant prehistoric cultural sites could be affected by levee construction.

Preparation date: November 8, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OHIO RIVER MAINSTEM NAVIGATION STUDY: MCALPINE LOCK REPLACEMENT, LOUISVILLE, KENTUCKY. AN - 36407622; 2464 AB - PURPOSE: Improvement of the McAlpine Locks and Dam at Louisville, Kentucky is proposed. The area affected by operation of the system includes all of Jefferson County, Kentucky and Floyd County, Indiana and most of Clark County, Indiana. The existing structures include one 110-foot by 600-foot auxiliary chamber, one 56-foot by 360-foot lock (out of service), and one 110-foot by 1,200-foot main chamber near the Kentucky shore. The dam is formed by a portion of Shippingport Island, the Louisville Gas and Electric Company power plant, the lower tainter gates, a fixed weir, and upper tainter gates connecting to the Indiana shore. These structures extend between Ohio River Miles 608 and 604. Approach to the locks is through the Portland Canal at the Kentucky shore. Integral to the project is the recently established Falls of the Ohio National Wildlife Conservation Area. In 1986, commercial traffic at the locks and dam was 53.4 million tons; this figure is projected to increase to 72.0 million tons by the year 2000 and 141.6 million tons by the year 2050. The tentatively recommended improvement plan would involve construction of an additional 1,200-foot lock in place of the existing auxiliary chamber. This would place two 110-foot by 1,200-foot locks into service. The new structure would have an upper sill minimum clearance of 18 feet (sill elevation 402 feet above mean sea level (MSL)), a lower sill minimum clearance of 18 feet (sill elevation 365 MSL), a floor elevation of 365 feet above MSL, and a 16-foot-high wall culvert. The system would be operational at river levels up to 18 feet. The project would include an eight-turbine hydropower plant with a total discharge capacity of 32,000 cubic feet per second (cfs). The swing bridge over the existing 1,200-foot lock at 27th Street would be replaced by a new bascule bridge. The estimated cost of initial construction is $219.4 million, based on 1989 price levels, and annualized costs are estimated at $19.5 million. The benefit-cost ratio is estimated at 1.6. POSITIVE IMPACTS: By improving the operation of the dam and locks, the project would provide for annual net benefits worth $10.8 million. Substantial delays due to slow chamber filling and actual system failures due to high-water overtopping would be eliminated from the system. Operation of the new system would reduce turbidity levels associated with river navigation by reducing queuing of tows in the upstream and downstream approach areas. NEGATIVE IMPACTS: An additional 170 cfs of flow would be required for lockages by the year 2050; this would represent an increase in the 7-day, 1-in-10-year low flow from 14 percent to 15 percent, resulting in a relatively insignificant reduction in hydropower production. Approximately 19 acres on the downstream end of Shippingport Island would be required for disposal of spoil generated by the project; this would represent 9 percent of the island. Access to public use areas at the project, including the visitor center, picnic facilities, and sightseeing accommodations, would be limited during the six-year construction period.

Preparation date: October 30, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PATTON ISLAND BRIDGE AND APPROACHES CROSSING THE TENNESSEE RIVER AND CONNECTING THE CITIES OF FLORENCE AND MUSCLE SHOALS, COLBERT AND LAUDERDALE COUNTIES, ALABAMA. AN - 36399407; 2370 AB - PURPOSE: Construction of a multilane bridge and approaches across the Tennessee River to connect Colbert and Lauderdale counties, Alabama is proposed. The 3.5-mile project would begin in Florence, near the intersection of Hermitage Drive and Helton Drive (State Route (SR) 157), extend southward across the Tennessee River, and terminate in Muscle Shoals at the intersection of SR 133. Two alignments were considered within the preferred project corridor. The area transportation plan calls for future upgrading and additional lane provisions for SR 133; these improvements would be accomplished as a separate project. The estimated cost of the project is $63.14 million, and the benefit-cost ratio is estimated at 6.2. POSITIVE IMPACTS: Provision of the bridge would enhance the safety of vehicular transportation and improve access by emergency vehicles. Economic growth in the local area would be promoted. In general, transportation between the cities of Florence and Muscle Shoals would improve significantly. The project would employ 350 to 375 workers during the employment season. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of 24 businesses, 21 residential units, three public/community facilities, 10 acres of prime farmland, and 29 acres of upland habitat. Some slight effect on river habitat would be expected, and a moderate effect on archaeological resources would be anticipated.

AN - 36407953; 2345 AB - PURPOSE: Implementation of tests and collection of data in support of research, development, and operational missions, including missions associated with the Strategic Defense Initiative (SDI), are proposed on Kwajalein Atoll within the Republic of the Marshall Islands. Kwajalein Atoll is a crescent-shaped coral reef that encloses the world's largest lagoon. The land area of the atoll is 5.6 square miles. Test range facilities and support services for continuing research, development, operational missions, operational space track missions, and SDI activities would be provided. More specifically, the action would involve the installation and testing of SDI sensing/tracking equipment and interceptor missile systems and implementation of five construction projects in support of base operations at the atoll. The proposed SDI testing would include the launch of target and interceptor missiles from Meck, Omelek, and Roi-Namur islands. Other tests would involve the sensing and tracking of reentry vehicles through the use of existing radars and a major new radar facility (the ground-based radar), as well as other sensing and tracking instruments (both existing and new). Meck Island, previously used for other programs, would be rehabilitated for SDI launches. Omelek Island, now used primarily for meteorological rocket launches, would be the site of new launch facilities. Construction on Kwajalein would include a desalination plant, family housing, and unaccompanied personnel housing. On Roi-Namur, new facilities would include a sewage treatment plant and a document control facility. POSITIVE IMPACTS: Project facilities and operations would accomplish a critical step in the testing of SDI elements, following the schedule established to ensure the timely development of a Strategic Defense System. Other missions assigned to the Kwajalein Atoll would be supported. NEGATIVE IMPACTS: Demands on Kwajalein groundwater would increase, particularly during drought periods. Marine water quality and biological resources in the vicinity of the atoll would decline due to inadequate solid and hazardous waste management practices, sewage effluent, dredging, and quarrying. Solid waste burning and power plant operations would degrade air quality, and power plant operations would generate noise in excess of federal standards. Tree stands would be displaced on Omelek. Intensification of military operations would place stress on rare giant clams and seagrass beds, and subsurface archaeological resources on Omelek could be disturbed. Population increases would place some pressure on housing and social and infrastructural resources.

AN - 36404409; 2399 AB - PURPOSE: The implementation of a flood control project for the Bassett Creek watershed in Hennepin County, Minnesota, is proposed. The watershed lies west-southwest of the downtown section of Minneapolis in a highly disturbed and industrialized area. This final supplement to the final environmental impact statement of July 1978 addresses changes in the design plan after it was determined that the proposed ponding (impoundment) area would have been located above a hazardous waste site, which required that the alignment of the flood control channel, as originally proposed, be changed. Like the original plan, the revised plan would involve structural and nonstructural measures. More specifically, the original plan would have involved the construction of a 1.5-mile underground conduit and deep tunnel, temporary storage areas, a permanent impoundment, channel modifications, embankments, floodwalls, culverts, and weirs. The ponding area at the mouth of the tunnel, proposed in the original plan, would not be constructed due to hazards from the contaminated waste site. Ponding during high runoff was intended to minimize the size and cost of tunnel construction. As a result, the newly revised plan would involve extending the creek channel enlargement for a distance of 1,500 feet upstream of the lower end in order to increase its capacity. In addition, 600 feet of new channel would be required to connect the creek to the new conduit. Although it was originally planned that the tunnel through glacial till be developed using a boring machine, economic analysis has demonstrated that the tunnel could be constructed more economically by surface excavation and placement of precast conduits. Floodplain evacuation, floodproofing, and continuation of floodplain regulation and flood insurance programs would constitute the nonstructural measures. POSITIVE IMPACTS: Flood protection provided to families and businesses would reduce economic losses, community disruption, and potential threats to public health and safety. Damages resulting from floods of less than a 100-year occurrence rate would be eliminated in portions of the watershed. Floodplain regulation would reduce future flood damages, and flood insurance would compensate owners for damages incurred from floods. NEGATIVE IMPACTS: Some trees would be removed to accommodate channel excavation. Approximately 152,000 cubic yards of excavated material would be placed in the Irving Avenue Dump Site, which is a hazardous waste facility. Channel excavation would expose currently stable creek banks to soil erosion and the creek to sedimentation by contaminated soils.

AN - 36404488; 2361 AB - PURPOSE: The Kummer Development Corporation, operating as the Adam's Rib Recreation Area, has applied for a permit to discharge fill material into Brush Creek, East Brush Creek, and adjacent wetlands in association with the development of a year-round destination resort in Eagle County, Colorado. Adam's Rib Recreation Area would develop the four-season's complex in conjunction with the proposed Adam's Rib Ski Area. The resort would be located within the drainages of Brush Creek and East Brush Creek approximately 14 miles south of the town of Eagle. The resort would focus on two major activity centers, to be constructed in two phases, involving 1,623 acres of developable private land. A special use permit has been granted by the Forest Service to develop skiing facilities on Adam Mountain and Mount Eve to provide for 9,000 skiers on approximately 3,000 acres of public lands in the White River National Forest. The development proposed in this statement would consist of the Brush Creek and East Brush Creek activity centers, which would provide 1,340 hotel rooms, 3,091 condominiums and other multifamily residential units, 500 single-family units, a commercial mall, and 250,000 square feet of commercial space. Additional base facilities would include a conference center and retail space. Infrastructure facilities would include parking, roads, underground utility lines, water pumpback systems, water supply and wastewater pipelines, a mass transit system (in the Vassar Meadow complex), and a 1.7-million-gallon-per-day tertiary wastewater treatment plant. Resort facilities would include an alpine ski area, a midmountain restaurant, a performing arts center, two 18-hole golf courses, and a recreation complex. Resort construction would be phased over a 10- to 25-year period, depending on demand. POSITIVE IMPACTS: Skiing and all-season recreational opportunities would increase significantly for the entire region. The facilities would accommodate 598,400 skier days per year. Other developed recreational opportunities, as well as fishing and big game hunting opportunities, would increase significantly. Area employment rolls would be increased substantially. NEGATIVE IMPACTS: The project would involve the removal of approximately 600,000 cubic yards of material and the placement of approximately 800,000 cubic yards of imported fill material to establish satisfactory site conditions for resort development. Wetlands associated with East Brush Creek, Nolan Creek, and Brush Creek drainages would be affected by the discharge of fill material. Fill activities would impact a total of 69.9 acres of wetlands. Approximately 900 linear feet of East Brush Creek would be relocated and reconstructed in the commercial core area of Vassar Meadow. An additional 200 linear feet of stream channel would be disturbed during construction, but these stream stretches, affected due to bridge crossings, would be restored. Six cultural resource sites that are under consideration for inclusion in the National Register of Historic Places could be affected. Wood fuel and automobile use would reduce air quality in the area somewhat. The influx of new residents and visitors would place pressure on public service infrastructures. Significant constraints would be placed on visitors to wilderness areas in the vicinity of the resort, and the visual character of the area would change drastically. Post development concentrations of some pollutants would exceed water quality standards without implementation of runoff control and treatment measures. Vegetation disturbances would be inevitable. Wildlife habitat associated with wetlands and the affected vegetation would be altered or lost, and wildlife would be disturbed by the influx of visitors. Fishing pressure could affect populations of Colorado River cutthroat trout, an endangered species. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: October 25, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CONSTRUCTION OF STATE ROUTE 267 ON NEW ALIGNMENT BETWEEN I-80 AND THREE MILES EAST OF TRUCKEE IN NEVADA COUNTY, CALIFORNIA. AN - 36404626; 2374 AB - PURPOSE: Construction of a State Route (S.R.) 267 bypass of the downtown Truckee area in Nevada County, California is proposed. Of the eight alternatives originally considered, only two have been deemed feasible. Alternative E would begin just east of the existing Route I-80/89N/267 Interchange, cross the Southern Pacific Railroad and the Truckee River with a bridge, and connect to existing Route 267 near the Truckee Airport. The existing Route 80/89N/267 Interchange would be removed. Alternative F would begin at the Route 80 /Fibreboard Undercrossing, where a new interchange would be constructed, and follow approximately the same bypass alignment as Alternative E south of the river, connecting to existing Route 267 near the airport. If Alternative F is constructed, the existing Route 80/89N/267 Interchange would remain, but the existing structure would have to be raised (to provide standard vertical clearance) and rehabilitated. Initial construction of either alternative would involve development of a two-lane access-controlled expressway (Phase 1), with climbing lanes provided when increases in traffic warrant (Phase 2). Rights-of-way width would be acquired immediately to provide for the four-lane facility. Earthworks would also be created to provide for the requirements of a four-lane facility. Noise control features could be incorporated into the project design. Under Alternative E, the costs of the the two-lane expressway, the two-lane expressway with climbing lanes, and four-lane facilities are estimated at $25.8 million, $34.1 million, and $40.0 million, respectively. Under Alternative F, the costs of the two-lane expressway, the two-lane expressway with climbing lanes, and four-lane facilities are estimated at $20.1 million, $22.0 million, and $28.6 million, respectively. POSITIVE IMPACTS: The bypass would remove through traffic from the downtown area of Truckee, easing both long-distance and local traffic movements. Creation of a grade-separated railroad crossing would eliminate motor vehicle/train conflicts, easing movement of police, fire, and other emergency and public service vehicles. Traffic movement in general would be eased by the grade-separated crossing. The bypass would encourage commercial development in the vicinities of the existing I-80/Route 267 interchange and the proposed Route 267 connection to existing Route 267 near the airport. NEGATIVE IMPACTS: Rights-of-way requirements for alternatives E and F would amount to 126 acres and 162 acres, respectively. Alternative E would result in the elimination of an undercrossing that mitigates vehicle /wildlife conflicts, particularly those involving migrating deer. The 100-year floodplain of the Truckee River would be crossed, and drainage facilities would encroach somewhat on the floodplain. One hazardous waste site would lie within the project rights-of-way. Approximately 20 acres of commercial timber would lie within the Alternative E rights-of-way, while 35 acres of commercial timber would lie within the Alternative F rights-of-way. Some sagebrush scrub and Jeffrey pine habitat would be displaced, and rural agricultural and open space lands would be traversed. Traffic-generated noise levels would be significant in the vicinity of the Ponderosa Fairway subdivision and could be somewhat significant in the Olympic Heights subdivision.

Preparation date: October 20, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NORTH DOUGLAS HIGHWAY EXTENSION CORRIDOR IDENTIFICATION, CITY AND BOROUGH OF JUNEAU, ALASKA. AN - 36399260; 2371 AB - PURPOSE: Identification of a transportation corridor for selection of an alignment to extend the North Douglas Highway a distance of 8.4 miles from its current terminus at Outer Point to Point Hilda on Douglas Island in the city and borough of Juneau, Alaska is proposed. The current action is not a proposal to construct a road. The preferred plan would involve construction of a 34-foot-wide, gravel-topped, two-lane road. The road would have the same centerline as the two- and four-lane paved roadways that could be developed in the future. This would ensure that the geometrics of the road would conform to any future construction and also that the road material would be useable within a future paved-road prism. Approximately 3.5 miles of the facility would be constructed on rockfill. Other highway design features would include permanent and temporary settling ponds, armor rock bank protection, and run-off drainage diversions. The estimated cost of the initial two-lane gravel highway is $20.4 million. POSITIVE IMPACTS: The new facility would help the city of Juneau handle a population increase of 7,900 by 1997 by opening a new area for development of housing and related amenities. Construction of the new roadway facility would provide land access to a proposed vessel landing at Middle Point, expediting transport of workers to the developing mine at Greens Creek on Admiralty Island. NEGATIVE IMPACTS: Existence of the highway would encourage development of currently undeveloped natural lands associated with a heavily wooded shoreline. Water quality in the Peterson Creek watershed could be degraded somewhat. Traffic levels on the existing North Douglas Highway would be increased by as much as 5,300 additional vehicles per day. Hunting for Sitka blacktail deer, black bear, waterfowl, and small game would be affected by the construction and use of the highway. Noise from construction and use of the highway could impact the 22 bald eagles nesting in the vicinity. A total of 214.9 acres of rights-of-way, including approximately 81.3 acres of wetlands, would be lost to other uses or disturbed.

Preparation date: October 16, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SMALL BOAT HARBOR, CHIGNIK, ALASKA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JANUARY 1988). AN - 36391504; 2394 AB - PURPOSE: Harbor development at Chignik, Alaska, located on the Pacific side of the Alaska Peninsula at the head of Anchorage Bay, is proposed. Since Chignik is accessible only by air or sea, no boat launching facilities would be required. One structure would be needed to provide necessary protection for the inner harbor. A 1,460-foot rubblemound breakwater would be developed for a nonbreaking wave height of 8.5 feet. The side slope of 1 vertical to 1.5 horizontal would be stable; the design crest elevation would be 20.5 feet above mean lower low water. The mooring area would total 4.8 acres, using conventional double-berth mooring for 55 vessels from 31 to 60 feet long, and single- and double-berth mooring for 15 larger vessels up to 120 feet long or more. The entrance and access channel area would be approximately 3.6 acres; it would be cut through the nearshore zone and would be subject to the erosive effects of wave conditions. The length-to-width ratio of the basin would be 3.2. Circulation would be improved by several design characteristics. The entrance would be aligned so that the inflow direction is parallel to the long axis of the basin, designed to allow two-way traffic for the 85-foot design vessel. Initial dredging would remove 360,000 cubic yards, and maintenance activities, implemented at 10-year intervals, would require removal of 16,000 cubic yards. A staging area of 4.4 acres would be needed for minimal parking, gangway access, and some storage. The total area covered would be 26 acres. The project would require 75,900 cubic yards of armor rock, which was to be quarried from an undeveloped rock source located in the Castle Bay area. This draft supplement to the final environmental impact statement (EIS) of January 1988 proposes deletion of the Castle Bay source as the designated quarry. The new quarry site would be selected by the contractor. This supplemental draft EIS also evaluates the overall environmental impacts of existing operating quarry sites using a typical, generic quarry site scenario. Total final EIS project costs were estimated at $10.0 million to construct, with a benefit-to-cost ratio of 1.2. POSITIVE IMPACTS: Under the preferred alternative, the harbor would provide protection at all times for vessels 30 feet to more than 120 feet long. The breakwater and inner harbor facilities would be designed for a 50-year storm event. The harbor would allow the local fishing fleet year-round harborage in Chignik. Residents in the area would be less dependent on private docks for anchorage and storage. A harbor would benefit the economy of the region. NEGATIVE IMPACTS: Indirect wildlife effects would be caused by close proximity to the harbor, such as increased noise, littering, and human traffic. Intertidal/subtidal habitat would be lost by dredge and fill activities, amounting to approximately 26 acres. There would be a significant impact on locally used clam beds. Harbor-related pollutants could enter harbor waters. Passerines, waterfowl, shorebirds, and seabirds might be dislocated because of construction activities and harbor operation. Maintenance dredging would be necessary over the life of the project.

Preparation date: October 16, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 71 IMPROVEMENTS BETWEEN INTERSTATE 10 AND STATE ROUTE 91, LOS ANGELES, SAN BERNARDINO, AND RIVERSIDE COUNTIES, CALIFORNIA. AN - 36405913; 2373 AB - PURPOSE: Improvements to 15.6 miles of Route 71 from the Holt Avenue interchange near Route 10 in the city of Pomona, Los Angeles County, California to State Route (S.R.) 91 in Riverside County, California are proposed. The corridor traverses three counties, two cities, and the Prado Flood Control Basins. The preferred alternative would involve implementation of a full freeway design within a depressed alignment. More specifically, the project would involve widening the highway cross-section to accommodate six to eight lanes north of Route 60 and four to six lanes south of Route 60, construction of grade separations at selected sites, improvements to the Route 60/Route 71 and Route 91/Route 71 interchanges, and provision of full interchanges to control access along the corridor. The freeway would begin in Los Angeles County at the Valley Boulevard/Holt Avenue interchange in Pomona and extend southeasterly along the current Route 71 alignment, and across the Route 60 freeway into San Bernardino County. It would continue along the approximate alignment of Route 71 through San Bernardino County and portions of Chino and Riverside County, with a connection at the current terminus of Route 71 at the Route 91 freeway. The freeway would be on new alignment from a point south of Chino Avenue, where it would cross the Chino Creek flood control channel, to Edison Avenue. The freeway alignment would include elevated, at-grade, and depressed sections throughout its length. The depressed sections would be in the city of Pomona from just north of Mission Boulevard to just south of North Ranch Road. The freeway would be elevated over Riverside Drive, Chino Avenue, and Grand Avenue. The roadway would be at-grade at Pipeline Avenue, with Pipeline Avenue carried over the freeway, raising up and over Carbon Canyon Road and Ramona Avenue before returning to the existing roadway elevation. From Soquel Canyon Road southward, the profile would be dictated by the high-water elevation of the Prado Flood Basin. Estimated costs of rights-of-way acquisition and construction are $30.0 million and $152.0 million, respectively. POSITIVE IMPACTS: Improvement of the S.R. 71 facility to full freeway standards would provide an acceptable level of traffic service and would enhance planned development and growth in the S.R. 71 corridor. This major northwest-southeast link in the regional highway system would continue to provide adequate service to Pomona, Chino, and Corona, as well as to other rapidly developing regions. Existing capacity deficiencies at many locations would be ameliorated. Construction activities would employ significant numbers of persons. NEGATIVE IMPACTS: Rights-of-way requirements, totalling 345 acres, would result in the displacement of 26 residential buildings, containing 72 residents, as well as 10 businesses. Acquisition of land would result in a $300,000 decline in the annual property tax base. New freeway features would constitute a substantial visual encroachment. Habitat to be displaced would include four acres of riparian brush, two acres of riparian woodlands, 20 acres of coastal sage scrub, and 100 acres of grasslands. Noise levels would exceed federal standards at 26 residential locations. LEGAL MANDATES: Executive Orders 11988 and 11990, Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.), and Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (42 U.S.C. 4601).

Preparation date: October 6, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FINLEY-EAST LAKE BOULEVARD EXTENSION, 26TH STREET NORTH TO CARSON ROAD, CITY OF BIRMINGHAM AND JEFFERSON COUNTY, ALABAMA (PROJECTS M-7173(1) AND M-7173(2)). AN - 36403202; 2369 AB - PURPOSE: Construction of a four-lane divided arterial highway within the city of Birmingham and Jefferson County, Alabama is proposed. The study corridor extends nine miles on a generally southwest-northeast axis in the Birmingham Valley. The southwest terminus would be on Finley Boulevard at 26th Street in North Birmingham, while the northeast terminus would be on Carson Road near 14th Avenue, N.W. The southwest terminus would lie approximately 1.5 miles north of the Birmingham central business district, and the northeast terminus would lie in the Birmingham suburbs near Center Point. The project would run along the northern boundary of the Birmingham municipal airport. Two distinct projects would be combined to form the overall project, namely, the Finley Boulevard Extension and the East Lake Boulevard Extension. The Finley Boulevard section would run from the southwest terminus at 26th Street to existing East Lake Boulevard at 43rd Street in Inglenook north of the airport, and the East Lake Boulevard Extension section would cover the remaining distance between 43rd Street and Carson Road. The sections would extend 3.5 miles and 5.5 miles, respectively. Elevated bridge structures would carry the main roadway from 26th Street to 40th Street, passing over five railroad lines. This section would feature interchanges at Huntsville Road on the west side of the Collegeville neighborhood and at Tallapoosa Street-Vanderbilt Road. A pair of two-lane, one-way traffic service roads would provide surface access between 27th Avenue and Tallapoosa Street. In the East Lake section, the project would follow existing East Lake Boulevard to the vicinity of Henry Graham Armory north of the airport, turn northward to follow Airport Road to 90th Place in Airport Highlands, diverge from Airport Road and become superimposed on Sherman Drive to Tarrant-Huffman Road. North of that point, the project would traverse undeveloped areas, paralleling Tarrant Spring Branch for approximately the last two miles to Carson Road. Interchanges would be provided at Lawson Road and Valley Crest Drive. One option would divert from this overall scheme on a two-mile segment in the middle of the East Lake section of the corridor. POSITIVE IMPACTS: The new highway would play a significant role in improving traffic movements between the Birmingham downtown area and the suburbs to the northeast out to the Center Point area by providing an alternative continuous traffic route. Access between North Birmingham, Collegeville, East Birmingham, and Inglenook would be improved. Delays and accidents at railroad crossings would be reduced due to separation of the two modes of transport. NEGATIVE IMPACTS: Rights-of-way requirements, ranging from 243.6 acres to 260.5 acres, would result in the displacement of 72 to 82 households involving 194 to 228 individuals, the Layman Chapel Church, 5 National Guard facility buildings, and utility lines. Numerous minors, black persons, and elderly persons would be among the displacees. The highway would encroach on the floodplains of Village Creek, Fivemile Creek, and a branch along Lawson Road.

Preparation date: October 4, 1989 N1 - Last updated - 2011-12-16 ER - TY - JOUR T1 - Surface Treatments for Concrete AN - 19093654; 9003759 AB - Freezing and thawing, penetration of salts, weathering, chemical attack, and erosion cause concrete surfaces to deteriorate. Surface treatment of the concrete with a material more resistant to these forces than concrete can slow or even eliminate the rate of deterioration. Surface treatment materials were separated according to viscosity, total solids, manufacturers ' recommended use, and chemical composition. Those tested fell into eight generic types: (1) acrylic, (2) hydrocarbon, (3)linseed oil, (4) polyurethane, (5) silane, (6) silicone, (7) siloxane, and (8) stearate. Results of the study indicate: siloxanes perform well as a generic-type concrete sealer, except in resisting cycles of freezing and thawing; acrylic mastic coatings for treatment of cracked concrete tested well in the laboratory, but field application results are not available; polyester resin coatings tested can be used effectively as abrasion-resistant coatings if applied to dry concrete; only those polyurethanes recommended by manufacturers for sealing concrete surfaces subjected to vehicular traffic performed effectively in laboratory tests; the high-molecular-weight methacrylate (HMWM) monomer systems can be used to seal cracks by topical application; two cementitious coatings tested were found effective for waterproofing concrete, from both positive and negative sides, and may minimize concrete deterioration resulting from freezing and thawing. Others tested did not produce the desired results; the addition of latex admixtures improves the freeze-thaw durability of shotcrete; and polypropylene fibers appear to reduce cracking caused by drying and shrinkage in latex-modified shotcrete.

The objectives were to illustrate amd explain impacts of shoreline erosion in CE reservoirs; identify probable causes of erosion; demonstrate means of measuring and analyzing bank erosion and recession; review traditional means of protecting shorelines; and describe alternative methods of controlling erosion using vegetation or a combination of vegetative and structural solutions. With proper planning, site preparation, appropriate plant establishment methods used at the right time, and postplanting monitoring and maintenance, reservoir shorelines can be vegetated to satisfy several objectives including shoreline erosion control. Revegetating reservoir shorelines can help prevent and control erosion, reduce turbidity and improve water quality, establish fisheries and wildlife habitat, and enhance reservoir esthetic values. Workshops on reservoir erosion control and revegetation will continue to provide innovative techniques to field personnel and draw upon others ' experiences in controlling reservoir shoreline erosion.

Advances in drilling, grouting and material technologies have been made during the last decade to the extent that the reliable remediation of major high dams can be conducted. It is highly significant that such treatments, usually carried out under extremely adverse conditions, can be used not only to seal off leakages but to bond the structure together again. There are three basic elements in ensuring effective treatment: (1) one must first make every effort to understand the cause of the problem. This understanding involves a detailed review of all the geological, constructional, and behavioral data available. Often this research forms the basis for executing a new phase of exploration (by coring) and monitoring; (2) once the probable cause for the cracking has been determined, the repair material can be selected. The repair material must be a true Binghamian fluid, not a suspension of particles. It must harden as soon as practical after injection to deliberately limit and control flow distances. It must have a reasonably constant and controllable viscosity until hardening; this viscosity must reflect the anticipated crack width. It must have minimal shrinkage on hardening. It must be durable, and it is usually required to bond efficiently to wet surfaces, under high hydrostatic or dynamic heads, often in low temperatures and so must have high tensile and shear strengths. It is usually advantageous to have modulus of elasticity significantly less than that of the concrete. It must have low surface tension in order to ease penetration into fine fissures. It must be easily and safely handled, with minimal environmental problems; and, (3) the performance of the grouting and of the structure should be continuously monitored during the repair. In this way, the grouting parameters can be varied as needed to optimize the procedure.

The lock is 110 ft wide by 600 ft long with 32-ft high lock walls. The upper and lower guide walls are 500 ft long. During the summer of 1985, Geotechnical Branch personnel performed a concrete condition survey on the lock walls. This survey included reviewing all available reports (basically, periodic inspection reports), visually inspecting and photographing all exposed surfaces, mapping cracks, sounding the surface, and taking cores. The petrographic examination indicated that cycles of freezing and thawing were the predominant cause of damage to non-air-entrained concrete. The depth of deterioration was 7 to 8 inches. Approximately 1 to 2 inches of the lock wall surface had already been lost as a result of surface abrasion of the damaged concrete. Consequently, the total depth of damage was 9 to 10 inches after approximately 48 years. The compressive strength of the sound concrete was 5,500 to 6,500 pounds/sq in. (psi). Because the deterioration was so extensive, a decision was made to completely rehabilitate the lock walls. District personnel decided to use preplaced-aggregate concrete (PAC) for the repair work. Shrinkage for PAC is about one-half or less that of conventional concrete. A minimum of 12 inches of concrete was removed by explosive blasting. High-pressure water was used to clean wall surfaces, and then anchors and reinforcing steel were installed. Forms for the PAC were installed on individual monoliths. Typically the resurfaced areas were about 10 ft high and 40 ft wide. Some defects (vugs) occurred on the concrete surface. Some of the vugs are the result of the method used to vibrate the forms and changing the grout flow requirement from 18 sec to 26 sec. Additionally, in some areas where PAC was to be used, conventional concrete was used because of the extensive armor that was placed in the lock wall, the difficulty in forming the areas, and the need to reopen the lock on time. The PAC surface has been subjected to two winters with cycles of freezing and thawing and two years of abrasion from barge traffic. Up to now the surface has performed well.

AN - 36391032; 2377 AB - PURPOSE: Reconstruction of U.S. Route 1 (Belair Road) from Silver Spring Road in Baltimore County to Maryland Route 152 in Harford County, Maryland is proposed. Two basic build alternatives, a six-lane cross-section and a four-lane cross-section, were considered before the six-lane alternative was determined to be preferable for the nine-mile project. The project would generally follow the existing horizontal alignment with widening on one or both sides, depending on physical constraints and environmental considerations. Where possible, consideration was given to modifying the rolling nature and steep grades on the existing alignment. A minimum of six through lanes would be provided throughout the project length. The typical cross-section would vary from segment to segment. Frequent median crossovers would be provided in urbanized areas. In less developed areas, the median crossovers would be restricted to major crossroads. Through park areas, a narrow New Jersey type concrete median would be used to minimize rights-of-way requirements. A number of options were studied for the Kingsville Community in an attempt to minimize community impacts and avoid impacts to historic sites. Depending on the option chosen, estimated costs of the project range from $97.8 million to $105.7 million. POSITIVE IMPACTS: Project improvements would alleviate safety deficiencies and provide adequate capacity for vehicular traffic through the year 2015; a 100 percent increase in traffic volumes is expected over the next 20 years. Access to and from areas in the adjacent northeastern Baltimore area would be eased. Linkages to Kingsville, Fork, Benson, Fallston, Belair, Forest Hill, Hickory, and Churchville would be improved substantially. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 21 to 22 residential structures housing 21 to 22 families and 52 to 60 businesses. Approximately 19.4 acres of parkland, 11.4 acres of prime farmland, 1.4 to 1.5 acres of wetland, and 1.5 acres of floodplain would be displaced. Traffic noise along the corridor would exceed federal standards at six sites.

AN - 36403132; 2352 AB - PURPOSE: Control of Eurasian watermilfoil in the waterways of the state of Washington is proposed. This draft supplement to the final environmental impact statement (FEIS) of October 1979 reviews and updates both geographic and treatment-related program elements in light of 10 years of experience in the program, which was initiated in 1980, and associated research advancements in aquatic plant management. The base condition is determined by the conditions prevailing in the aquatic plant management program as described in the 1979 FEIS. Mechanical and physical treatment methods currently under consideration include mechanical harvesting, rotovation, suction dredge, bottom barriers, fragment barriers, and hand removal. Chemical herbicides under consideration include 2,4-D, endothall (dipotassium salt), dichlobenil, diquat, and fluridone (Sonar). The current program involves treatment of 91 acres in lakes Washington, Union, and Sammamish to clear navigation in intensively used areas. A concurrent program would prevent infestations in the Okanogan River and Osoyoos Lake from spreading to unaffected waters. Geographic changes to the limits of the program within the state would involve the addition of the Pend Oreille River between Box Canyon Dam and the Idaho border, which was added to the program in 1982; Swofford Pond on the Cowlitz River in Lewis County, which was treated with fluridone (Sonar) in 1988 and 1989; and the deletion of the Okanogan-Columbia rivers near Malott, Washington, which were treated with 2,4-D from 1981 through 1983, but are no longer proposed for treatment under the program. The tentatively selected program would involve continuation of the basic program with the addition of a stipulation allowing the use of the Sonar herbicide. POSITIVE IMPACTS: Management of the nuisance plant would remove obstructions to water-related recreation and prevent plants from spreading to uninfested areas. NEGATIVE IMPACTS: Mechanical harvesting, rotovation, and suction dredging would remove all bottom biota and cause temporary turbidity. Herbicides would kill target infestations rapidly, causing rapid decomposition of plants and, hence, resulting in the loss of dissolved oxygen from affected waters. This would result in fish mortality. Some public recreational activities would be temporarily restricted in chemically treated areas, and booms used for harvesting and rotovating would mar scenery and hinder navigation.

Preparation date: September 22, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED LAND ACQUISITION FOR YAKIMA FIRING CENTER, KITTITAS, YAKIMA, GRANT, AND BENTON COUNTIES, WASHINGTON (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1987). AN - 36399064; 2347 AB - PURPOSE: Expansion of the Yakima Firing Center (YFC) by acquiring approximately 63,000 acres of land adjacent to the present YFC boundaries and two sites along the east shore of the Columbia River is proposed. The YFC military training center is a subinstallation of Fort Lewis, located in Yakima, Kittitas, Grant, and Benton counties, Washington, approximately seven miles north of the city of Yakima. The YFC is used for military field training, primarily by the 9th Infantry Division (motorized) (MTZ), U.S. Army Reserve, and National Guard to improve their military readiness. The YFC also serves the Air Force, Navy, Marines, Coast Guard, some foreign military forces, and others in carrying out various military training activities. The lands to be acquired include a northern expansion area extending from the northern YFC boundary to Interstate 90, an eastern expansion area consisting of the old Chicago, Milwaukee, St. Paul, and Pacific Railroad rights-of-way between the existing YFC and the Columbia River, and a crossing site on the east bank of the Columbia River between the river and State Highway 243, north of the Priest Rapids Wildlife Recreation Area. Military use of the proposed expansion lands would include maneuvers by both wheeled and tracked vehicles, foot traffic (maneuvers), overland flights by helicopters and high-performance aircraft, bivouac and staging activities, weapons firing, and river crossing on a year-round basis. No permanent population occupies the present expansion areas, although a number of single-family residences and low-density rural settlements occur adjacent to the areas, the largest of which is the Desert Aire Retirement Community located on the eastern bank of the Columbia River. This draft supplement to the draft environmental impact statement of June 1987 addresses possible changes in the force structure of the 9th Infantry Division. It evaluates the environmental effects of using a mechanized force on any acquired lands, as well as other effects associated with training on such lands. POSITIVE IMPACTS: Expansion of the YFC would increase its area by 63,000 acres, adding 62,000 acres of rangeland to the north of the existing YFC, rights-of-way along the eastern boundary, and two river crossing sites on the east bank of the Columbia River, opposite the existing YFC. In the interest of national defense, the Army would acquire this land to accommodate the growing operational demands of the YFC and to properly support its combat readiness mission. Expansion of the YFC would also allow the 9th Infantry Division (MTZ), other 1 Corps components, reserve components, and the National Guard additional flexibility in conducting large-scale military training activities and river crossing exercises. The latter are an integral part of land warfare, and the exercises must be practiced regularly. Acquisition of the eastern expansion area would provide the installation with river access and would facilitate security, fire control, and movement/access along the eastern boundary of the YFC. Acquisition of the Milwaukee Road corridor would provide a relatively level north-south access route on the east border of the YFC and eliminate occasional accidental trespassing on private lands. It would also eliminate the need to acquire ""as required'' training permits, which limit the Army's flexibility in planning and conducting realistic training exercises. NEGATIVE IMPACTS: Adverse environmental effects would affect cultural resources, recreational opportunities, wildlife habitat, and quality of life for area residents. Mitigation measures for these impacts are proposed. The Army would control future oil, gas, and mineral exploration in the expansion areas. Increased erosion would result from military maneuvers and vehicular activity. River crossing activities would impact fish migration and rearing and could interfere with future commercial navigation on the mid-Columbia River. Increased troop, vehicular, and air support activities would disturb resident and migratory birds and animals. Weapons firing and aircraft operations would increase noise levels.

AN - 36404965; 2395 AB - PURPOSE: The construction of a sand transfer system to support the Canaveral Harbor shoreline restoration and nourishment project in Brevard County, Florida, is proposed. This document is a draft supplement to the final EIS of May 1972 on the overall beach erosion control project for the Cape Canaveral area of Brevard County. The improvements proposed in this statement would provide for the southward movement of sand to bypass the Canaveral Harbor entrance, thereby reducing erosion of the shoreline channel. The transfer system would include five jet pumps, a pipe catwalk, an operations building, booster stations, and connecting pipeline and valves as required. The jet pumps would be located approximately 150 feet north of the north jetty and would be spaced at intervals of 60 feet between mean high water and 6 feet below mean high water in a line parallel to the north jetty. The project would also involve extending the south jetty for a distance of 500 feet, with sand tightening of the entire structure to reduce erosion and requirements for channel maintenance dredging by intercepting northward movement of materials. A program to prevent smothering of sea turtle hatchlings would be implemented. The estimated first cost of the project is $4.6 million, while annual maintenance costs are $200,000. The estimated benefit-cost ratio is 4.0. POSITIVE IMPACTS: In general, the project would contribute to the replacement of erosional losses to the city of Cape Canaveral beachfront and the reduction of excessive shoaling in the Canaveral Harbor entrance channel. Sea turtle nesting habitat would be preserved. NEGATIVE IMPACTS: Public use of the beach would be disrupted during nourishment operations, and free-swimming marine organisms near the shoreline would suffer from periodic turbidity. Benthos in the offshore dredging area would be destroyed, as would benthos covered by nourishment materials.

AN - 36391069; 2403 AB - PURPOSE: Designation of eight permanent ocean dumping sites in the vicinity of Long Island, New York and New Jersey is proposed for material dredged to maintain area waterways. The sites, all of which are currently interim sites, would receive materials dredged from the inlets of Rockaway, East Rockaway, and Jones and Fire islands, New York, and Shark River, Manasquan, Absecon, and Cold Spring Harbor, New Jersey. Each site lies near the area from which material would be dredged. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means for disposal of material dredged from the canal, ensuring the continued usefulness of the inlets for navigational purposes. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, localized burial of benthic organisms, and temporary mounding of substrate. Although each site is located close to the shore, environmental analyses indicate that use of the sites would have a negligible impact on the surrounding environment due to the inert nature of the dredged material combined with the relatively small site of each area.

The bypass would begin at a point 0.5 mile south of the May Creek bridge, follow the north side of May Creek drainage, and skirt the eastern edge of the state park to intersect with existing U.S. 101 approximately 0.5 mile north of the Humboldt /Del Norte county line.

From its high point on the east side of the state park, the road would begin a descent at a grade of 4 to 6 percent for approximately 1.5 miles, followed by a slight upgrade for approximately 1.0 mile. The downgrade on the final 4.6 miles would be approximately 6 percent. Large embankments and long cut areas would be required. This draft supplement to the final environmental impact statement of February 1984 on the highway construction project proposes three possible new sources of gravel for the manufacture of aggregate needed to complete the third stage of the bypass project, which would begin in the spring of 1990 and involve placing the base and paving, and installing a drainage system. Extraction and processing of approximately 500,000 cubic yards of gravel would be required to produce material for the subbase, base, and asphaltic-treated base, and the asphalt concrete needed to complete the bypass project. Gravel processing would include crushing, sorting, washing, and manufacturing of the final product. Available gravel source sites include the Blake Bar property located on the Klamath River just south of Klamath Glen, an active two-mile reach of Turwar Creek just north of Klamath Glen, and the Tracy property located adjacent to the downstream end of the Blake Bar property. Alternatives under consideration could involve the use of one or various combinations of these sites. POSITIVE IMPACTS: The bypass would remove through traffic from the existing portion of U.S. 101 within the park and improve commercial and long-distance travel on the only north-south highway in the north coast region of the state. Congestion caused by slow-moving tourists passing along the segment of highway that traverses the park would be eliminated by separating through traffic from tourist traffic. Extraction would enlarge channel capacity, thereby reducing flood risk. NEGATIVE IMPACTS: The project would require 1,128 acres of rights-of-way, including 631 acres of land belonging to Simpson Timber Company, and would necessitate clearance of nearly 400 acres of second-growth redwood forest, an acre of wetland, and 4.5 acres of old-growth redwoods. Lands within the Redwood National Park and Prairie Creek Redwoods State Park would be displaced. Approximately 882 acres of land would be severed from the remainder of the holdings of the Simpson Timber Company. Required earthwork for cuts and fills would be extensive. A temporary decrease in air quality due to dust from extracting and processing operations is expected. Odors may result from asphalt processing. Some disturbance of wildlife habitat may occur.

AN - 36403274; 2402 AB - PURPOSE: Continued use of the Massachusetts Bay Disposal Site, formerly the Foul Area Disposal Site, in Massachusetts for dredged material disposal is proposed. The site is located in Massachusetts Bay in approximately 90 meters of water and is two nautical miles in diameter. The center of the site is at 42 degrees, 25 minutes, 7 seconds west longitude and 70 degrees, 34 minutes north latitude, approximately 22 nautical miles east of Boston. The site is currently operating as an Environmental Protection Agency-approved interim dredged material disposal site. The U.S. Army Corps of Engineers (COE) has disposed or permitted disposal of 2.8 million cubic yards of dredged material at the site over the past 12 years. Final site designation would not constitute approval for actual disposal of dredged material; it would only serve to identify an ocean disposal alternative for individual dredging project reviews. All dredged material proposed for ocean disposal would continue to be evaluated on a project-by-project basis by the COE. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means for disposal of material dredged from the region, which includes areas extending from Gloucester to Plymouth, Massachusetts, for navigational purposes. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, as well as short-term changes in the grain size of surficial sediments, localized burial of benthic organisms, and temporary mounding of substrate.

Preparation date: September 18, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SOUTHEASTERN EXPRESSWAY, FROM I-464/I-64 TO ROUTE 44, CITIES OF CHESAPEAKE AND VIRGINIA BEACH, VIRGINIA. AN - 36391000; 2382 AB - PURPOSE: Construction of the Southeastern Expressway is proposed to provide for east-west travel through the cities of Chesapeake and Virginia Beach, Virginia. The expressway would be located in the extreme southeastern section of Virginia known geographically as the Hampton Roads region. Project study limits extend from Interstate 64 (I-64) between Bainbridge Road and Indian River Road in Chesapeake to the Norfolk-Virginia Beach Expressway (Route 44) between Laskin Road and Birdneck Road, a length of approximately 21 miles and a width averaging approximately 3.5 miles. The expressway would be a multilane, grade-separated, access-controlled, divided highway. Interchanges would be constructed at major existing and proposed crossroads. The design would incorporate eight lanes and would have a design speed of 70 miles per hour. Initial corridors under consideration have been reduced to eight alternative groups providing for a total of 39 possible alignments. Alignments extend from 17.9 to 21.6 miles. The estimated project costs range from $354.6 million to $545.2 million, depending on the alignment selected and specific design considerations. POSITIVE IMPACTS: Traffic congestion on existing routes would be relieved through redistribution of traffic patterns. Safety, efficiency, and convenience within the corridor would be improved. The number of accidents on area arterial roads would decline significantly. NEGATIVE IMPACTS: Rights-of-way acquisitions totalling 982 to 1,334 acres would result in the displacement of 87 to 660 families; displacements could be exacerbated due to the shortage of low- to moderate-income housing in the area. As a result, minority group residents could be inconvenienced. Nine to 68 businesses would be displaced, along with 6 to 12 nonprofit organizations, 1 school and 4 churches, and 34 to 109 public institutional facilities. Parkland, farmland, wetlands, forestland, and archaeologically, historically, and architecturally significant sites also could be impacted, as well as associated wildlife habitat, and two locally important scenic waterways. Five to 15 neighborhoods would be disrupted, including minority neighborhoods. Noise levels would exceed federal standards in the vicinity of some sensitive receptors. The endangered Dismal Swamp southeastern shrew would be impacted.

AN - 36405869; 2379 AB - PURPOSE: Widening of Interstate 84 (I-84) between the 181st Avenue interchange and the Troutdale interchange from four to six lanes in Multnomah County, Oregon is proposed. The project would extend 4.7 miles within the city limits of Fairview, Wood Village, Gresham, and Troutdale. All interchanges within the project termini would be modified. The partial interchange connecting I-84 with Sandy Boulevard west of NE 223rd Avenue would be replaced by a full interchange at NE 207th Avenue, with access to Sandy Boulevard. A new roadway would be constructed from the interchange ramps to Sandy Boulevard. The interchange at NE 238th Avenue would be rebuilt as a standard diamond interchange. The Troutdale interchange would be modified to provide adequate vertical clearance and improve ramp terminal intersections. A bicycle path would be constructed within the highway rights-of-way, and grade separations would be provided at major cross streets. Graham Road would be realigned slightly, and the two bridges carrying I-84 over Graham Road would be replaced. The intersections between the ramps and Marine Drive and Graham Road would be changed to include traffic signals and channelization. In order to mitigate wetlands impacts, 1.5 acres of palustrine wetlands would be created from existing uplands; these wetlands would constitute an extension of an existing marsh. Special features would be added to the project design to contain hazardous waste spills due to the existence of a public water well field northwest of the project corridor. The estimated cost of the project is $53.7 million for construction and $9.3 million for rights-of-way acquisition. POSITIVE IMPACTS: Expansion of the freeway's capacity would improve traffic flow and decrease accident potential and operating costs. Federal Interstate and Defense Highway standards would be met. The NE 207th Avenue interchange would serve traffic from all directions, unlike the existing interchange that only serves traffic to and from the east. An at-grade railroad crossing on NE 238th Avenue would be replaced by a grade separation. Significant noise impacts would be reduced for numerous residences and one motel. NEGATIVE IMPACTS: Rights-of-way development would result in the filling of 1.5 acres of wetlands and displacement of 27 residences and 7 businesses. A total of 48 residences would be affected by noise. There would be a potential for hazardous waste material spills from vehicles using the freeway.

Preparation date: September 8, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MIAMI HARBOR CHANNEL, FLORIDA: IMPROVEMENTS FOR NAVIGATION (REVISED FINAL ENVIRONMENTAL IMPACT STATEMENT). AN - 36383584; 2396 AB - PURPOSE: Improvement of Miami Harbor in Biscayne Bay, Florida is proposed to provide increased depths in the existing federal and other, locally created, channels. Biscayne Bay is a shallow saltwater sound on the Atlantic coast near the southern end of the Florida peninsula. The immediate tributary area for Miami Harbor is Dade County, which depends on the port for some basic commodities. This revised final environmental impact statement (FEIS) covers modifications in the plan recommended in the FEIS. The plan recommended in the FEIS would involve modification of the harbor to provide a channel 41 feet deep and 500 feet wide from the open ocean to the existing beach line, tapering to 39 feet deep and 400 feet wide at the beach line, and remaining at those dimensions to the Fisher Island turning basin. Under the FEIS plan, the South Lummus Island channel would have terminated at a turning basin centered around the existing Lummus Island turning basin; the new turning basin would be dredged to a depth of 39 feet and a diameter of 1,600 feet. Under the revised plan proposed in this revised FEIS, the South Lummus Island channel would be extended 9,200 feet westward of the Fisher Island turning basin. The South Lummus Channel would have a depth of 44 feet and a width of 500 feet from the open ocean to the existing beach line, a depth of 42 feet and a width of 500 feet from the beach line to Cut 3 station 33+00 (near the Fisher Island turning basin), and a depth of 42 feet and a width of 400 feet from the Fisher Island turning basin to the west end of the container berths located on Lummus/Dodge Island. The channel would terminate in a turning basin with a depth of 42 feet and a diameter of 1,600 feet. All dredged material would be dumped in the Miami Ocean Dredged Material Disposal Site, which is presently undergoing final designation for use by the Environmental Protection Agency. The first cost of the recommended plan is now estimated at $65.6 million. POSITIVE IMPACTS: Planned improvements would allow vessels with increased draft and tonnage to call at the harbor, resulting in transportation savings to shippers. NEGATIVE IMPACTS: Because most of the dredging would be done within the existing channel, where periodic disruptions from maintenance dredging and ship movements have not permitted the establishment of a diversified fauna, adverse environmental impacts would be restricted to seagrasses at the turning basin and impacts associated with blasting. The loss of marine seagrasses would be restricted to newly dredged areas. Although the seagrasses in the area are sometimes fed upon by manatees, it is unlikely that this endangered species would be seriously affected. Offshore disposal would result in cumulative impacts in the disposal area in that it would retard development of biota.

Stem segments of plants were first immersed in suspensions of fungal propagules for 24 h and then washed to remove all but the tightly attached component of the population. Inoculation was followed by two growth cycles of 3 days each. At the start of each cycle, washed plants were transferred to a mineral salts medium to provide an opportunity for the attached fungal populations to grow. After each growth period, plants were again washed, and fungal populations in the medium (nonattached), loosely attached and tightly attached to the plant, and within the plant (endophytic) were assayed by dilution plating. The fungi differed in the extent to which they attached to water milfoil and in their ability to grow in association with it. There were relatively few significant differences among the tightly attached fungal populations after 24 h, but growth of the better colonizers led to a greater number of significant differences after 4 and 7 days. In addition, the better colonizers showed sustained regrowth of loosely and nonattached fungal propagules in the face of intermittent removal by washing. A milfoil pathogen, C. gloeosporioides, was the only endophytic colonizer; it was also among the best epiphytic colonizers but was not demonstrably better than A. curvulum, a fungus commonly found as an epiphyte on water milfoil. The yeastlike hyphomycete A. pullulans was the only fungus that consistently failed to establish an increasing population on the plant.

Clear Fork stream flows through agricultural and forested areas, whereas Rocky Fork stream flows through industrialized Mansfield, Ohio, where it receives industrial and municipal effluents. Four sites on each stream were sampled monthly for fishes during July 1982 through August 1983. Incidence of fin erosion was significantly greater (P0.05). Incidence of fin erosion in fish from polluted sites was inversely correlated with water temperature (P0.05). Nevertheless, total incidence of deformed fishes at polluted sites (0.53%) seemed to be elevated compared to total incidence of deformed fishes at unpolluted sites (0.28%). Comparative studies between fish from streams suspected of being polluted and fish from nearby unpolluted, reference streams should be used to define effects of chronic pollution.

AN - 36404661; 2308 AB - PURPOSE: Widening of 8.5 miles of Glenn Highway in the extreme northern portion of Anchorage and the southern portion of the Matanuska-Susitna Borough, Alaska is proposed. More specifically, the project would proceed from a point near the village of Ekluta to a point approximately 0.33 mile east of the Glenn Highway/Parks Highway intersection and, on the Parks Highway, to a point approximately two miles northwest of Glenn Highway. The project would involve widening the last two-lane segment of the Glenn Highway between Anchorage and the Parks Highway to a six-lane divided highway. Project design would provide for full control of access, with interchanges at the Old Glenn Highway, Knik River Access Site, Parks Highway, and the New Trunk Road. Three new driving lanes would be provided on the southbound side of the highway and an additional driving lane would be added to the northbound side of the highway over most of the length of the project. The existing bridge across the northern channel of the Knik River would be reconstructed to accommodate northbound traffic, and a new bridge would be constructed to accommodate southbound traffic crossing the river. The bridge over the middle channel of the Knik River would be eliminated as recommended by the project's hydrological study. The southern channel of the Knik River would be crossed via new bridges constructed for both northbound and southbound traffic. North of Rabbit Slough, the highway would be realigned to the east for the proposed Glenn Highway/Parks Highway interchange. New access roads connecting local roads to the proposed New Trunk Road interchange would be provided north of the Parks Highway/Glenn Highway interchange by extending Trunk Road to Nelson Road. No access would be provided to the property east of the Glenn Highway between Rabbit Slough and the Parks Highway. POSITIVE IMPACTS: Expansion of the capacity of the highway would meet the needs of the increasing number of residential and business establishments in the Matanuska-Susitna Borough and Anchorage areas that have been growing steadily since 1970. Commuters working in Anchorage and travelling to and from residential areas in the borough would benefit from reduced congestion. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of three to seven residences and businesses, a loss of 254 acres of wetlands, a loss of fish and wildlife habitat, and encroachment on floodplains. Noise generated by traffic on the facility would affect residential areas. Implementation of full control of access would alter access and travel patterns in the area.

Preparation date: August 18, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CORE CREEK BRIDGE REPLACEMENT, ATLANTIC INTRACOASTAL WATERWAY BRIDGE, CARTERET COUNTY, NORTH CAROLINA. AN - 36408803; 2320 AB - PURPOSE: Replacement of the Core Creek Atlantic Intracoastal Waterway (AIWW) bridge in Carteret County, North Carolina is proposed. The bridge crosses the AIWW at mile 195.8 and is located in the coastal plain of Carteret County. It is part of North Carolina Highway (NC) 101, which runs from Beaufort to Havelock, North Carolina. The proposed replacement bridge would be a two-lane, high-level, fixed-span structure with a 65-foot vertical clearance over the AIWW. The crossing, which would lie approximately 900 feet south of the existing bridge, would involve construction of 4,500 feet of new roadway and a 3,000-foot bridge. Borrow sites for necessary fill would be located on either side of the AIWW; each of the two sites would cover approximately 25 acres. The approach for the bridge would leave NC 101 at a point approximately 4,100 feet west of the AIWW. The alignment would reconnect with NC 101 on the other side of the bridge, approximately 3,000 feet east of the waterway. The total length of the project is 7,500 feet, with 2,700 feet of approach on the west and 1,800 feet of approach on the east. Bridge approaches on each side of the waterway would require placement of approximately 300,000 cubic yards of fill. Fill height at the bridge abutments would be approximately 30 feet on the west and 40 feet on the east, with widths of 220 feet and 280 feet, respectively. Fill width would taper as the alignment approaches NC 101. Rights-of-way widths vary from 360 feet at the highest point of the approach fills to 140 feet at the connections with NC 101. Additional rights-of-way would be required for two-lane connector roads at each end of the alignment. POSITIVE IMPACTS: Unsafe operating conditions characterizing the bridge, associated with structural deterioration, blind curves, and inadequate roadway width, would be remedied. The connector roads would facilitate access to the new road and access within the community. NEGATIVE IMPACTS: Rights-of-way development would result in relocation of 5 permanent residences and 3 secondary residences (mobile homes) and displacement of 13 acres of pine forest, 11 acres of mixed pine /hardwood, and 50 acres of pine plantation. Approximately 9.5 acres of palustrine forested wetlands would be filled; wetland losses would include 6.0 acres of deciduous pine wetlands and 3.5 acres of pine-dominated wetlands. Approximately 1,200 square feet of estuarine bottom would be affected by the construction of pier footings. Removal of the existing bridge would result in the loss of a structure that may be eligible for the National Register of Historic Places. The new bridge would constitute a visual obstruction, affecting area aesthetics.

AN - 36405943; 2317 AB - PURPOSE: Completion of the final five-mile section of Maryland Route (M.R.) 100 between U.S. 29 and Interstate 95 (I-95) in eastern Howard County, Maryland is proposed. The study area is bordered on the west by U.S. 29, on the east by I-95, on the north by M.R. 103, and on the south by M.R. 108. The facility would extend southeast from the proposed U.S. 29/M.R. 100/M.R. 103 interchange, cross M.R. 104 approximately 600 feet north of the existing M.R. 108/M.R. 104 intersection, and swing northeast to connect to the existing I-95 /M.R. 100 interchange. The freeway would have six lanes and a 34-foot median; some sections of the freeway would be built in stages, so that the six-lane section would be deferred. Two options are under consideration regarding the intersection of M.R. 100 and M.R. 104. Connections would be considered at the proposed Long Gate Parkway, Executive Park Drive, Center Park Drive, M.R. 104, the proposed extension of Snowden River Parkway, and Meadowridge Road (M.R. 103). The estimated costs of engineering, rights-of-way acquisition, and construction/design for the project are $2.9 million, $4.5 million, and $42.7 million, respectively. POSITIVE IMPACTS: Provision of a controlled-access, high-speed highway within the corridor would improve east-west traffic movements, relieve congestion on the existing street network, and provide a safe and efficient highway link to move people, goods, and services more quickly and directly. The facility would form part of the regional transportation network that has been conceptually approved since the late 1950s. The outer suburbs of the Baltimore metropolitan area would be connected via a network for which this project would constitute a vital component. NEGATIVE IMPACTS: Rights-of-way development would result in displacement of three residences, 5.67 acres of Brampton Hills Community Park, 16 acres of wetlands, 4.87 acres of floodplains, and 56.5 acres of woodlands. Approximately 1,800 feet of stream relocation would be required. Noise generated by highway traffic would exceed federal standards at 16 locations, and one archaeological site would be affected during construction.

AN - 36408117; 2314 AB - PURPOSE: The widening of a 17-mile segment of Colorado State Highway (SH) 82 between a point east of Basalt and Aspen in Pitkin County, Colorado, is proposed. The two-lane facility would be widened to a four-lane highway. Specific termini are a point 0.75 miles east of Basalt and the intersection of 7th and Main streets on the west side of Aspen. Seven alternatives, including a No-Build Alternative (Alternative 1), which would include minor, short-term safety and maintenance improvements, are considered in this draft EIS. Alternative 2A would provide for widening along existing SH 82, with some realignment northeast of the Aspen/Pitkin County Airport. Alternative 2B would provide for widening along the existing alignment, with some realignment southwest of the airport. Alternative 3, Alternative 4, Alternative 5, and Alternative 6 would all provide for widening along existing SH 82 between Basalt and Old Snowmass. From that point, Alternative 3 would cross the Roaring Fork River and parallel the Denver & Rio Grande Western Railroad tracks through Snowmass Canyon, widen along the existing highway between Snowmass Canyon and Shale Bluffs, proceed on a new alignment to northeast of the airport, and create a new highway connection to Main Street in Aspen. Alternative 4 would cross the Roaring Fork River, follow the northeast side of the valley floor through Snowmass Canyon, widen along the existing alignment between Snowmass Canyon and Shale Bluffs, realign the highway to southwest of the airport, and widen along the existing highway between the airport and Aspen. Alternative 5 would create a one-way couplet through Snowmass Canyon, with eastbound lanes on the existing alignment and westbound lanes parallel to the railroad rights-of-way, widen along the existing alignment between Snowmass Canyon and Shale Bluffs, realign the highway to northeast of the airport, and create a new highway connection to Main Street in Aspen. Alternative 6 would duplicate Alternative 3, except that the airport realignment would bypass the southwest side of the airport. POSITIVE IMPACTS: Safety and capacity of SH 82 would be enhanced, and traffic congestion on the facility would be relieved. The facility would provide infrastructural support for the economy of Pitkin County. Provisions for realignment in the vicinity of the airport would provide needed space for expansion of the airport. NEGATIVE IMPACTS: The development of the highway would require the relocation of residences and businesses and encroach on the property of residences and businesses that are not relocated. Rights-of-way development would also encroach on sites eligible for the National Register of Historic Places and on recreational and open space and wetlands. Construction activities would result in sedimentation of the Roaring Fork River. Wildlife habitat would be displaced, and potential for animal/vehicle collisions would be increased. The visual quality of the Roaring Fork Valley would be degraded.

AN - 36402996; 2341 AB - PURPOSE: Implementation of flood control measures along Swan Creek in the Heatherdale area of the city of Toledo, Lucas County, Ohio is proposed. The recommended plan would involve construction of approximately 3,100 feet of combined levee and floodwall sections along the left bank of Swan Creek, channel relocation along 540 feet of the right bank, and internal drainage features, including three outfalls and a small ponding area. The levee section would extend approximately 2,900 feet, while the floodwall would extend approximately 200 feet. The levee crest elevation would gradually increase from 597.0 National Geodetic Vertical Datum (NGVD) at the downstream end of the project to 598.0 NGVD at the upstream end. The floodwall, consisting of concrete-faced steel sheet pile, would be located adjacent to the Bethel Lutheran Church. Riprap erosion protection would be placed along approximately 1,300 feet of creek bank. Approximately 540 feet of channel relocation would be required in the vicinity of the intersection of Glencove and Heatherdale drives; the channel would be relocated approximately 75 feet to the southwest. The ponding, which would cover 1.6 acres and have a capacity of 9 acre-feet, would be located immediately east of Lomond Drive. Other internal drainage features would include three outfalls, a drainage ditch, and an inlet pipe for the ponding area. A simple flood warning system would be incorporated into the project. Land requirements would include acquisition of permanent easements on 6.0 acres and temporary easements on 4.4 acres, and fee simple acquisition of 3.3 acres. The Hoffman Road Landfill would be used for borrow material and disposal of project debris. The cost of the project is estimated at $1.47 million, and the benefit-cost ratio is estimated at 1.11. POSITIVE IMPACTS: Project features would provide protection from a flood event occurring once every 100 years. With existing average annual damages of $172,630 and residual average annual damages of $10,230, the recommended 100-year levee plan would eliminate approximately 94 percent of the average annual damages in the Heatherdale area. Benefits include flood reduction, elimination of flood insurance costs, and generally increased affluence in the protected area. Riprap bank protection would diversify benthic habitat along the creek. Nonpoint source water pollution of Swan Creek would decline. NEGATIVE IMPACTS: Six acres of floodplain habitat, 2,500 linear feet of streambank vegetation, and one acre of privately managed upland habitat would be cleared prior to construction. Construction activities would disturb benthic communities and reduce air and water quality in the vicinity of project activities. Access to the Swan Creek streambank would be impeded by the levee and floodwall, and 2.6 acres of open space would be lost to public use.

AN - 36399353; 2398 AB - PURPOSE: Flood protection through renovation and construction of five miles of levees along the banks of the Raccoon River and Walnut and Jordan creeks near their confluence in Des Moines and West Des Moines, Polk County, Iowa is proposed. The recommended plan would involve raising an existing levee and constructing new levees along the north bank of the Raccoon River, with a tie-off along the north bank of Jordan Creek and along the west bank of Walnut Creek. Ponding areas to provide internal drainage and two borrow areas would be included in the proposed plan. This final supplement to the final environmental impact statement of June 1977 is based on a general reevaluation of the project design undertaken in 1988. The reevaluation resulted in: (1) reaffirmation of the economic feasibility for flood control and recreation development along the Raccoon River and Walnut Creek; (2) modification of the flood control alignment to incorporate new floodplain delineation limits and developments completed since 1975; (3) implementation of policy changes regarding recommended levels of protection and project cost-sharing; (4) renewal of statements of local sponsor support; and (5) provisions to avoid adverse environmental effects. As a result of the reevaluation, the level of protection afforded by the project design has been decreased from protection against the 200-year frequency flood to protection against the 100-year frequency event. Specifically, the project as currently proposed would consist of four miles of earthen levee, 900 feet of concrete floodwall, six mechanical closure structures, two sandbag closures, two pump stations, four ponding areas, three road ramps for access, three road ramps for maintenance, and two new access roads. Recreational facilities to be developed in association with the project would include 2.8 miles of bicycle paths, five bicycle ramps, two railroad crossings, two road crossings, one scenic overview, one parking lot, and one single-lane boat ramp to provide access to the Raccoon River. The estimated cost of the project is $17.8 million, with an annualized cost of $1.8 million. Flood control and recreational benefit-cost ratios are 1.8 and 1.3, respectively. POSITIVE IMPACTS: The levees would provide 100-year flood protection for approximately 900 acres within the cities of Des Moines and West Des Moines. The protected land areas include 904 residential, 227 commercial, and 11 public structures. Average annual flood control and recreational benefits would be worth $3.2 million and $1.4 million, respectively. NEGATIVE IMPACTS: A portion of the levee would be superimposed over Hoak Drive and would border an adjacent wooded area for approximately 1,500 feet between the roadway and Walnut Creek; disturbance to woody vegetation in this area would be likely. Approximately six acres in the vicinity of Denman Woods would be displaced. Ponding areas would be inundated during flood flows. Borrow areas would include agricultural land. One residence and two businesses would be displaced by the project.

Preparation date: July 10, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TOPSHAM-BRUNSWICK BYPASS, FROM ROUTE I-95 IN TOPSHAM TO ROUTE 1 IN BRUNSWICK, MAINE (PROJECT DE-0091(801)). AN - 36391111; 2316 AB - PURPOSE: Construction of a two- to four-lane bypass of Topsham, Maine for Routes 196 and 201 is proposed. Two alignments, extending approximately 2.8 and 2.9 miles, are under consideration. Either alignment would extend from the Interstate 95 (I-95)/Route 196 interchange southeast to Route 1. In addition, four alternative treatments of the bypass/Route 201 intersection are under consideration. Bypass Alternative 1 would involve widening of Route 196 to four lanes between I-95 and a point west of Route 201 in Topsham. This alternative would proceed eastward as a two-lane roadway through largely undeveloped forestland and continue south to cross the Maine Central railroad and Elm Street. A connector between the bypass and Foreside Road would be provided just south of the railroad crossing. The bypass would cross the Androscoggin River on a bridge wide enough to accommodate future expansion to four travel lanes. Alternative alignment 1 would terminate at a three-level interchange with Route 1, just east of the railroad bridge. Alternative 2 would have the same alignment as Alternative 1, except in the area east of Route 201, where it would pass north close to the Maine Central Powerline, rejoining Alternative 1 east of the railroad. Options for the bypass/Route 201 intersection would include at-grade and grade-separated designs. Depending on the combination of alternatives chosen, project cost estimates range from $31.1 million to $38.6 million. POSITIVE IMPACTS: The bypass would improve routes that provide critical access between Interstate 95 and Route 1 in Topsham and Brunswick. The local, through-town route, which is heavily congested, would be relieved of through traffic. Approximately half of the traffic currently using the Frank J. Wood bridge would be diverted to the bypass crossing, providing significantly greater total river crossing capacity. Access to downtown areas and businesses would be improved by the reduction in nonlocal traffic and the easing of Main Street congestion. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of 3 to 10 residences and 4 to 8 businesses, depending on the intersection alternative selected. An historic house and associated outbuildings would have to be relocated, as would archaeological resources. Approximately 3.57 to 4.12 acres of wetlands would be taken, depending on the intersection alternative selected, and 1.79 acres of floodway would be displaced.

During the October 1986 flood of the Mississippi River, it became apparent that it would be necessary to relocate a portion of the existing levee on Chouteau Island. The new section of levee required a gravity drainage structure with a concrete gate-well and a relatively short gravity drainage pipe. The levee relocation project allowed the District to gain experience with new procedures and products. The products included high-density polyethylene (HDPE) pipe and fiber-reinforced plastic (FRP). HDPE is corrosion resistant and allows more effective joint connections than the corrugated metal pipe (CMP). The FRP products are highly resistant to corrosion and eliminate the need for periodic maintenance, such as the painting required even for galvanized metal. A sluice gate made from a synthetic material was also selected for use in the structure. The original design of the Chouteau Island gate-well called for a cast-in-place structure; however, the contractor submitted for approval a precast, two-section gate-well with the same dimensions and reinforcement as the original structure. The precast plan was approved. Both a cast iron gate and alternative synthetic gate were specified for this project. The contractor chose to furnish a synthetic gate with a steel matrix encapsulated in a high-density polymer. Usually, metal attachments are used for gate-well structures. Because of their exposure to the outside environment, and to provide a structure as maintenance free as possible, attachments chosen for the Chouteau Island gate-well are FRP products.

AN - 36408638; 2286 AB - PURPOSE: Disposal of chemical warfare agents by the Johnston Atoll Chemical Agent Disposal System (JACADS) on Johnston Atoll in the southern Pacific Ocean is proposed. This final supplement to the final environmental impact statement (FEIS) of November 1983 covers the disposal of liquid and solid process wastes associated with nerve agents GB and VX and blistering agent HD. Johnston Atoll is located at 16 degrees, 44 minutes north latitude and 169 degrees, 31 minutes west longtiude, making it one of the most isolated atolls in the Pacific Ocean. Johnston Island, the largest island of the atoll, has increased from 60 acres to 625 acres due to dredge and fill operations. The disposal system for the chemical agents proposed in the FEIS would involve construction and operation of an incineration facility on the western peninsula of the island and the disposal of incinerator wastes via drying, drumming, and storage on the island. A liquid incinerator would be used to destory GB and VX agents, while disposal of HD would be via a process involving neutralization and incineration. Waste materials would be reduced to solid salts and then compacted and packaged in 55-gallon drums. Alternatives for disposal of solid wastes produced as byproducts of the incineration and packaging process include: (1) disposal by ships in a deep-water site approximately 13 to 19 miles south of the atoll; (2) drying of liquids into inorganic salts and shipping both the salts and other solid process wastes to an authorized landfill or storage site in the United States; (3) discharging of liquid wastes into the ocean via an outfall pipeline from Johnston Island; and (4) drying of liquid brine into salts and storage, along with all unrecyclable solid wastes, on Johnston Island for an indefinite period. Recyclable scrap metal produced by JACADS operations would be sold or disposed of via ocean dumping or placement in a landfill in the United States. The preferred method of disposal would involve a combination of ocean disposal of liquid waste (now prohibited by the Ocean Dumping Ban Act); the sale of the scrap metal; and the shipment of the nonsaleable solid waste to an appropriate U.S. landfill. POSITIVE IMPACTS: By providing a permanent means to dispose of unserviceable or obsolete chemical agents and the byproducts of the destruction process, JACADS would enhance safeguards protecting the biosphere against releases of toxic agents. Ocean disposal of solid wastes would create hard substrate for benthic organisms. Encapsulation of wastes on the atoll would provide habitat for seabirds and protection of shore areas from erosion. NEGATIVE IMPACTS: Construction of ocean disposal sites for wastes would stress and destroy reef organisms, and ocean disposal of solid wastes would bury resident benthos. Use of a U.S. landfill could result in the contamination of water resources due to disaster.

Preparation date: June 29, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - AN EXPRESSWAY ON NEW ALIGNMENT BETWEEN I-5 AND FRONTIER DRIVE IN THE CITY OF OCEANSIDE, COUNTY OF SAN DIEGO, CALIFORNIA. AN - 36390510; 2237 AB - PURPOSE: Construction of an expressway along the San Luis Rey Valley from Interstate 5 (I-5) to Mission Avenue near Frontier Drive in the city of Oceanside, San Diego County, California is proposed. A narrow width expressway would be built up and into the hillside that lies along the corridor. Major project features would include acquisition of rights-of-way and grading for an ultimate six-lane expressway; construction of two 12-foot lanes in each direction; provision of a 30-foot median that would include two 5-foot shoulders; provision of 10-foot outside shoulders and 12-foot wide recovery area outside shoulders; placement of a 10-foot strip of riprap bench outside and below the north side recovery area for use as a future bicycle path that would be built by other interests; and construction of a bridge structure from southbound I-5 to eastbound State Route (SR) 76. Additional features include mitigation of wetlands and destruction of least Bell's vireo habitat in an area near the west end of Oceanside Municipal Airport; placement of a 6-foot-high, 2,600-foot long combination earthen and concrete jersey barrier to protect the wetland mitigation area; realignment of Nevada Street/Riverside Drive near I-5; and rehabilitation of freshwater/brackish marsh west of I-5. Connections to the expressway would be provided at the northbound I-5 exit ramp to eastbound SR 76, southbound I-5 exit ramp to eastbound SR 76, westbound SR 76 left-turn pocket to the northbound I-5 entrance loop ramp, and signalized at-grade intersections at Loretta Street, Benet Road, Airport Road, Foussant Road, and Mission Avenue. POSITIVE IMPACTS: By providing a bypass for a section of Mission Avenue, the expressway would relieve heavy traffic congestion on that facility and separate long-distance and local traffic flows. Traffic-generated noise along Mission Avenue would decline significantly. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 80 acres of land within the city of Oceanside and relocation of up to 14 homes and 23 families, 7 commercial establishments, and 40 aircraft hanger units. A total of 60 jobs would be lost due to displacements. Noise levels would increase by three decibels or more on the A-weighted scale for 17 homes; federal noise standards would be exceeded at 7 homes. Three least Bell's vireo territories, containing a total of 5.1 acres of wetland habitat, would be impacted, and up to 2,000 Dudleya viscida would be removed. Cut-and-fill slopes, with heights up to 190 feet, would result in scars that would remain for as many as 10 years before mature plantings would blend them into the native hillside.

F-123-1(1)). AN - 36403940; 2250 AB - PURPOSE: Construction of the Northern Wake Expressway in Wake and Durham counties, North Carolina is proposed. The expressway would extend from N.C. 55 near Morrisville to U.S. 64 near Knightdale, bypassing the northern portion of the city of Raleigh. The four- to six-lane controlled-access facility would extend 28.5 to 33.3 miles along a new alignment. Three alternative alignments were evaluated for the portion of the alignment northwest of Raleigh International Airport between Interstate 40 (I-40) and U.S. 70. Four alternative alignments were considered east of Creedmoor Road through the Shannon Woods subdivision. Two alternative alignments were investigated between Litchford Road and Fox Road. Three alternative alignments were considered east of the Neuse River. Noise abatement measures could be implemented at 266 sites. POSITIVE IMPACTS: Traffic congestion within the Raleigh central business district would be lessened significantly by the removal of through traffic from local streets. Travel times for through travelers would decline significantly, and emergency response time would decrease. Objectives of numerous local and regional transportation plans would be achieved. Access to the Raleigh International Airport would be eased significantly. NEGATIVE IMPACTS: Rights-of-way requirements could result in impacts to 5 cemeteries and displacement of 75 to 131 businesses, nonprofit organizations, and households. Possible passage of the expressway through the Shannon Woods and Thorpshire Farms subdivisions could affect community cohesion in those neighborhoods. The corridor to be affected contains 128 cultural resource sites, including 18 standing structures, 59 historic archaeological sites, and 51 prehistoric archaeological sites; 11 of the prehistoric sites are not eligible for inclusion in the National Register of Historic Places. Five historic properties that could be affected are listed or are eligible for listing on the National Register. One alignment alternative would directly impact the northwest corner of the Knightdale Quarry, and a portion of the Rowland Sanitary Landfill would lie within the construction limits of another alternative. A total of 736 noise-sensitive receptors would lie within the corridor. Approximately 7.6 percent (186 acre-feet) of storage capacity would be lost from the Stirrup Iron Creek flood control lake due to placement of fill. From 22 acre-feet to 55 acre-feet would be lost from the Brier Creek flood control lake. Stormwater runoff would increase by 2.6 percent within the study area. From 86.3 to 104.5 acres of floodplains and 111.9 to 142.2 acres of wetlands would be impacted by the project.

Preparation date: June 16, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SAUGUS RIVER AND TRIBUTARIES FLOOD DAMAGE REDUCTION, LYNN, MALDEN, REVERE, AND SAUGUS, MASSACHUSETTS. AN - 36391418; 2269 AB - PURPOSE: Implementation of a plan to control coastal flooding problems along the coastal floodplain of the Saugus River and its tributaries in Massachusetts is proposed. Lying approximately five to ten miles north of Boston, the 4,000-acre study area includes portions of the cities of Lynn, Malden, and Revere and the town of Saugus; the area has a resident population of 20,000. The study area frequently suffers from coastal flooding. The recommended regional plan would combine three miles of existing flood damage reduction measures with 3.5 miles of new measures to create a linked defense line that would provide protection against the Standard Project Northeaster to nearly the entire study area and prevent flooding up to 10 feet deep. The principal component of the plan would involve construction of tidal floodgates at the mouth of the Saugus River that would prevent tidal surges from entering the river and flooding land throughout the study area. The floodgates would span 1,275 feet at the mouth of the river and include 600 feet of gated openings so as to maintain both safe passage for navigation and natural tide levels and flushing patterns in the estuary. The gates would be closed only when projected tide levels were expected to cause significant damages. Closure would generally occur two to three times each year, with an average closure lasting one to two hours during the peak of each tide. During very severe coastal storms, such as a recurrence of the blizzard of 1978, the gates would be closed for longer periods and possibly for more than one high tide. If the sea level should rise, generally, the frequency of closures would increase. A combination of dikes, walls, stone revetments, beaches, and sand dunes would be developed at Lynn and Point of Pines. Preservation of three miles of existing seawalls at Revere Beach, as well as construction of a wall and a park dike behind that beach would also be needed. The $78.9 million plan would have an average annual cost of $8.9 million, including $325,000 per year for operational costs, maintenance, and major replacements. The estimated benefit-cost ratio is 1.2. POSITIVE IMPACTS: Flood damage prevented by the project would result in average annual benefits worth $10.8 million, for an average annual net benefit of $1.9 million. Flood damage would be reduced for 5,000 buildings and the associated infrastructure, including 20 miles of floodprone public transportation arteries. The need for and cost of emergency public services would decline significantly. The project would provide public parkland along the 3,400-foot dike. A safe port of refuge during coastal storms would be provided for the 400-vessel fleet moored in the estuary. NEGATIVE IMPACTS: Project activities would result in the loss of approximately 10 acres of mostly intertidal habitat at the location of project features along the coast; this loss would be mitigated through the creation of 10 acres of clam flats at the Interstate 95 embankment.

AN - 36402695; 2255 AB - PURPOSE: Improvement of the Route 31 crossing of the James River in Charles City, James City, and Surry counties, Virginia is proposed. The existing crossing is served by the Jamestown-Scotland Wharf Ferry System. Alternatives under consideration include improvement of ferry service, construction of bridge or tunnel crossings of the river, and construction of new or improved approach roadways. These alternatives would involve the construction of two-lane facilities to modern design standards and the use of portions of existing rights-of-way, as well as acquisition and development of new rights-of-way. Alternatives range in length from 6.7 to 9.2 miles. The improved ferry alternative would involve the addition of boats and scheduled trips. The current four-boat fleet would be expanded to six, and operations would be increased for the peak period from a two-boat to four-boat schedule at 15 minute intervals; a fifth boat would be added during future peak seasonal periods. Depending on the alternative chosen, project cost estimates range from $29.5 million for the improved ferry alternative to $352.0 million for the most expensive tunnel alternative. POSITIVE IMPACTS: Current and future traffic service within the corridor served by Route 31 would be improved significantly. Permanent river crossing alternatives would increase access to commercial, cultural, educational, and employment centers in the Jamestown corridor. NEGATIVE IMPACTS: Construction of a tunnel or a bridge would result in the displacement of up to one household. Land losses could include 34 to 46 acres of farmlands, including 22 to 36 acres of prime farmlands, 31 to 74 acres of forests, and 71 to 120 acres of terrestrial habitat. As many as six prehistoric sites and 12 historic sites could be affected by structural crossings of the river. Carbon monoxide levels would rise slightly should a structural crossing be chosen.

Preparation date: June 13, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TYPHOON AND STORM SURGE PROTECTION, AGANA BAYFRONT AREA, TERRITORY OF GUAM. AN - 36391609; 2266 AB - PURPOSE: Implementation of a typhoon and storm surge protection project is proposed to provide coastal flood control for the Agana Bayfront area of the Territory of Guam. The Agana Bay shoreline stretches 3.5 miles from Adelup Point on the west to Dungca's Beach and Alupat Island on the northeast. The shoreline is bordered by a wide, fringing coral reef flat, varying in width from 1,200 to 2,700 feet. The project would include construction of a concrete-rubble-masonry (CRM) wall along the seaward shoulder of Marine Drive fronting the urban center of Agana, a concrete floodwall extension to the Agana River flood control project, a concrete floodwall (New Jersey barrier) down the middle of Marine Drive in Apurguan, three pumping stations to enhance interior drainage, and upland diversions to divert surface runoff. A five-foot-high CRM wall would extend 4,800 feet on the seaward side of Marine Drive fronting downtown Agana. A seven-foot-high section of CRM wall would extend 1,500 feet through Paseo de Susana Park. The left bank of the Agana River Flood Control Project would be improved. A five-foot-high section of concrete floodwall would extend 2,600 feet down the middle of Marine Drive in Apurgan. Nine road closures would be provided. The average annual cost of the project is estimated at $417,000; the benefit-cost ratio is estimated at 1.55. POSITIVE IMPACTS: Commercial and recreational uses along the bay shoreline would be protected from flooding due to storm surges and typhoons. The project design would provide protection against the 500-year event. The aesthetic character of the area would be maintained, as would access to the beaches. Average annual benefits resulting from the project would be valued at $231,000. NEGATIVE IMPACTS: Approximately one acre would be committed for the construction of floodwalls. Although the walls would not affect the aesthetic value of the bayfront area or impede public access to the beaches, the New Jersey Barrier segment in Apurguan could adversely affect business by limiting accessibility. A few trees would have to be relocated. Construction activities would result in temporary degradation of air quality and could uncover unknown cultural deposits.

ROUTE 58 TO ROUTE 29 (NORTH OF BLAIRS), PITTSYLVANIA COUNTY, DANVILLE, VIRGINIA (STATE PROJECT 6265-071-102, PE 102, FEDERAL PROJECT F-045-1(111)). AN - 36382693; 2256 AB - PURPOSE: Completion of the final section of the Route 265 Danville Expressway, located primarily in Pittsylvania County, Virginia is proposed. A short southern section of the highway, as well as part of the Franklin Turnpike Extension, would be located in the city of Danville. The 8.9-mile project would extend from Route 58 approximately one mile east of the Danville city limits to Route 29 north of Blairs. The section of the Route 265 expressway extending from Route 58 (east of Danville) to Route 29 (south of Danville) is already open to traffic. The typical cross-section for the facility would feature two 12-foot travel lanes in each direction, separated by a 60-foot and variable median. The project would proceed in a northerly direction, passing just east of the intersection of Routes 360 and 732, where the alignment would proceed nearly due north to Route 695 then turn in a northeastward direction crossing Route 721 just west of its intersection with Route 695. The alignment would then continue to cross Route 719 west of its intersection with Route 695, cross Route 719 just west of its intersection with Route 29, and cross Route 726 just west of its intersection with Route 29. Three short extensions or relocations, involving Route 360, the Franklin Turnpike Extension, and the Fall Creek Spur, would be implemented. Interchanges along Route 265 would be provided at Route 29, Route 726, and the Franklin Turnpike Extension. At-grade crossings would be located at the Franklin Turnpike Extension and Route 360. POSITIVE IMPACTS: The facility would provide a needed through route for traffic in the vicinity of Danville, improve access to Danville Municipal Airport, and ease the movement of emergency vehicles and rescue equipment. The new highway would adhere to the Danville Area Transportation Study Year 2000 Transportation Plan, Danville Comprehensive Plan, Pittsylvania Comprehensive Plan, and Fiscal year 1986-1988 Transportation Improvement Program for the Danville Urbanized Area. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 23 families and 5 businesses, the loss of approximately 101 acres of prime and unique farmlands, and the loss of approximately 438 acres of medium- to low- quality wildlife habitat. Ambient noise levels along the corridor would increase significantly.

Preparation date: June 12, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED PERMIT APPLICATION, BLACK MESA-KAYENTA MINE, NAVAJO AND HOPI INDIAN RESERVATIONS, ARIZONA. AN - 36390350; 2205 AB - PURPOSE: Issuance of permits to consolidate all Peabody Coal Company-owned and -operated mining and mining-related activities within the Black Mesa-Kayenta mine in Arizona is proposed. The permits would allow for surface coal mining and reclamation activities during the life of the mine. Currently, the Black Mesa-Kayenta mine, located approximately 125 miles northeast of Flagstaff, and 10 miles southwest of Kayenta, Arizona, consists of two separate but adjacent mining operations. The two units are the Black Mesa mine, which produces approximately 5 million tons of coal per year, and the Kayenta mine, which produces approximately 7 million tons per year. The proposed life-of-operations permit area would cover 62,753.34 acres of Hopi and Navajo tribal lands. The applicant would produce 292 million tons of coal from the new disturbance area between 1986 and 2011. Mining and reclamation activities would continue through 2023 (the proposed life of the mine). The applicant has previously been awarded two permits to mine coal at the complex. Between 1970 and the end of 1985, mining activities disturbed 4,480 acres within these two permit areas. The proposed federal permit would encompass the previously issued permits under one permit, authorize the applicant to disturb an additional 13,618 acres throughout the remaining life of the mine, and to upgrade 114 of the existing mine-related facilities to meet current federal performance standards. Coal would continue to be extracted via the dragline and truck-and-shovel open-pit methods and would be processed using existing in-place facilities owned and operated by the applicant. Processed coal would be transported from the Black Mesa Mine to the Mohave Generating Station via an existing slurry pipeline and from the Kayenta Mine to the Navajo Generating Station via the existing Black Mesa and Lake Powell Railroad. POSITIVE IMPACTS: New activities, authorized under the permit, would result in the production of 292 million tons of coal between 1986 and 2011. The applicant, which employs 1,000 persons at the mine, would continue to provide employment to local residents; 90 percent of the current employees are Native Americans. Regional power needs would continue to be met. NEGATIVE IMPACTS: Vegetative diversity would be impacted severely due to the conversion of 9,046 acres of pinyon-juniper woodlands and 4,485 acres of shrubland to grassland. Major socioeconomic impacts would occur to the Hopi Tribe's fiscal status and ability to provide human services over the long term. Mining activities would create fugitive dust, displace grazing land, and damage cultural resources. Outcrop and other topographic features characterizing the mine sites would be leveled, and sacred ceremonial sites could be degraded. Cropland within the area would be displaced, and formation of acid and other toxins would degrade soil quality and reduce the vegetative carrying capacity of the affected lands. Surface and groundwater levels could decline due to pumping of the N-aquifer. Wildlife habitat, including that of certain threatened or endangered species, could be affected. The population base of the Hopi and Navajo reservations could be changed. Regional transport and recreation facilities could be stressed.

Preparation date: June 8, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - THIRD HARBOR TUNNEL, INTERSTATE 90/CENTRAL ARTERY, INTERSTATE 93 (SOUTH BOSTON HAUL ROAD), BOSTON, MASSACHUSETTS (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1985). AN - 36407324; 2245 AB - PURPOSE: Extension of Interstate 90 (I-90) (Massachusetts Turnpike) from its terminus at the Central Artery in Boston across Boston Harbor to a new terminus in East Boston, Massachusetts is proposed. The project, which would be known as the Third Harbor Tunnel, would be located entirely in the city of Boston in Suffolk County. The one-way tunnel in Fort Point Channel would carry all northbound traffic to a widened and depressed Central Artery. This draft supplement to the final environmental impact statement of August 1985 addresses construction of the South Boston Haul Road, an early construction traffic mitigation measure for the Central Artery /Third Harbor Tunnel I-93/I-90 project. The Haul Road would be a two-lane, limited-access truck route for construction-related vehicles, for commercial truck traffic, and for buses destined to and from Logan Airport via the proposed cross harbor ferry, a separate construction period mitigation measure. The Haul Road would be built substantially within an existing depressed railroad rights-of-way. The alignment would connect Dorchester Avenue and Congress Street with access to the Massport Haul Road via Congress and B streets. Beginning on the west side of Dorchester Avenue, the Haul Road would traverse the existing Massachusetts Bay Area Transit Authority (MBTA) Cabot Yard parking lot to gain access to the existing depressed freight railroad rights-of-way of the Consolidate Rail Corporation (Conrail). The roadway would follow the west side of the tracks for its full length, approximately 1.1 miles, to a terminus at existing Congress Street. The project would also include installation of new drainage and railroad facilities. The drainage facilities would direct stormwater through a new 16-inch flow force main and a new 24-inch high flow force main under Dorchester Avenue. Both would run to a new 42-inch gravity storm drain to be located west of Dorchester Avenue and south of West Fourth Street to a new outlet structure at the southern end of Upper Fort Point Channel. Other project actions would include the replacement of railroad tracks, relocation of a freight loading dock, and construction of other railroad facilities. POSITIVE IMPACTS: Construction of the Haul Road would maintain surface street traffic patterns during the extended construction period of the Artery /Tunnel project. Completion of the Haul Road at the earliest possible date would be important to the success of the Artery /Tunnel project and the improvement of existing traffic circulation conditions. Truck traffic on South Boston streets would decline substantially, significantly improving circulation within this area of the city. NEGATIVE IMPACTS: The Haul Road would displace 228 surface parking spaces on two public properties and one private property. Approximately 18 acres of land presently owned by four parties would be permanently acquired. An additional eight acres would be acquired via easements for construction period and drainage easements. Rail track and utility relocations would be necessary, and one Conrail loading dock and an MBTA office trailer would be relocated. Truck traffic on the Haul Road during peak hours in 1993 would result in noise levels above existing levels on surface streets in the corridor. Truck-generated noise levels within 150 feet of the Conrail cut would exceed federal standards for some land uses. Approximately 51,000 cubic yards of material, including some hazardous materials, would be excavated during the project. The Boston Crown Glassworks archaeological site could be affected.

Preparation date: June 7, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RELOCATED MARYLAND ROUTE 32 FROM MARYLAND ROUTE 108 TO PINDELL SCHOOL ROAD, HOWARD COUNTY, MARYLAND (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1977). AN - 36401629; 2243 AB - PURPOSE: Improvement of Maryland (MD) Route 32 from Pindell School Road to MD Route 108 in central Howard County, Maryland is proposed. MD Route 32 extends from Westminster in Carroll County to proposed Interstate Route 97 near Annapolis in Anne Arundel County, a distance of approximately 59 miles. The relocated highway segment under consideration would begin at the existing northbound lanes of MD Route 32 just west of MD Route 108 and pass through the Trotter Road area approximately 2,360 feet north of existing MD Route 32. In the vicinity of the W. R. Grace Property and Stretmater Pond, it would shift north to avoid impacts to the pond and residences along the south side of old MD Route 32. The alignment would then proceed easterly to meet the existing MD Route 32 construction east of Pindell School Road. Within this segment, full diamond interchanges would be constructed at existing MD Route 108 and Pindell School Road. A cul-de-sac would be constructed at Trotter Road on both the north and south sides of relocated MD Route 32. The project would also include construction of two service roads, one connecting existing MD Route 32 to relocated Sanner Road/Pindell School Road on the south and the other on the north, connecting Cedar Lane to the W. R. Grace and Riverhill Game Farm property entrances. Relocation of MD Route 32 and the construction of service roads, together with MD Route 108 improvements, would be built to current state and federal highway standards. Improvements to Trotter Road and Pindell School Road would meet county standards. The typical roadway section for MD Route 32 would consist of two 24-foot roadway surfaces with a 46-foot median, and 4-foot inside and 10-foot outside shoulders within a minimum rights-of-way of 300 feet. A box culvert would be constructed where relocated MD Route 32 would cross over Cricket Creek, and a bridge structure would carry relocated Pindell School Road/Cedar Lane over the Middle Patuxent River. The estimated cost of the project, in 1988 dollars, ranges from $41.0 million to $45.0 million, depending on the service road option chosen. POSITIVE IMPACTS: Additional highway capacity would be available in central Howard County, a rapidly developing area within the Baltimore-Washington corridor. The existing two-lane segment would be replaced by a controlled access, high-speed, east-west facility, relieving much of the congestion on the existing roadway network by redirecting truck and commuter traffic. Traffic using relocated MD Route 32 would no longer be diverted through Clarksville. The completion of the project would create a continuous link between Interstate Route 70 near Cooksville in Howard County and the city of Annapolis in Anne Arundel County. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of one resident, 1 acre of public land, 29 acres of natural woodland habitat, 2.35 acres of wetlands, 3.52 acres of floodplains, and 28.5 acres of prime farmlands. Eight streams would be crossed. Two archaeological sites would be affected by construction activities. Three noise sensitive areas would be exposed to traffic noise in violation of federal standards.

AN - 36405427; 2257 AB - PURPOSE: Improvement of U.S. Highway 18/151 in the vicinity of the city of Verona in Dane County, Wisconsin is proposed. The study section extends four miles from County Trunk Highway (CTH) G west of Verona to CTH PD east of Verona. Average daily traffic (ADT) on U.S. 18 /151 within central Verona was approximately 13,000 to 14,000 vehicles per day in 1987. By the design year of 2012, the ADT is expected to increase to more than 20,000 vehicles, a 40 percent increase. Three build alternatives are under consideration: widening the existing highway from two to four lanes, with a median, through Verona; constructing a 2.2- to 4.0-mile bypass north of Verona; and (3) constructing a 1.3- to 3.4-mile bypass south of Verona. Two northern bypass routes and four southern bypass routes are under consideration. Regardless of the route selected, if a bypass option is selected, the highway would be a four-lane divided facility consisting of two 12-foot lanes in each direction, separated by a 50-foot-wide grassed median and flanked by 10-foot outside shoulders. Bypass construction would require a minimum rights-of-way of 228 feet. If selected, a bypass alternative would have interchanges at either end of the highway. A northern bypass would also provide access, via an interchange, at CTH M, while a southern bypass would provide additional interchanges at State Trunk Highway 69 and CTH PB. All local roads crossing a bypass route would be maintained via grade separations. Alternative 1 would begin west of Verona and west of Nine Mound Road and would extend approximately 1.3 miles east to meet the existing four-lane section east of Verona. This alternative, which would pass through Verona, would consist of two 12-foot-wide travel lanes in each direction, separated by either a raised median (with turning lanes) or a 14-foot-wide two-way left-turn lane. The minimum required rights-of-way width would vary from 84 to 88 feet. On-street parking would be prohibited. The estimated cost of Alternative 1 is $3.8 million. Depending on the exact alignment chosen, the estimated costs of alternatives 2 and 3 range from $10.1 million to $13.3 million and $5.6 million to $12.4 million, respectively. POSITIVE IMPACTS: Upgrading this principal arterial would improve transport for long-distance travelers crossing the state. Access to and from Wisconsin would be enhanced, and economic development within the region surrounding the corridor would be promoted. Bypass construction would reduce the accident rate along this section of the highway by 12 percent, and relieve congestion within Verona that is caused by mixing through and local traffic. NEGATIVE IMPACTS: Rights-of-way requirements for bypass alternatives would result in the displacement of 29 to 96 acres of farmlands, severance of 3 to 5 farms, and possible encroachment into Badger Prairie Park and Military Ridge Trail. Upland forestlands, wetlands, and floodplains would be lost due to bypass construction, but acreages for any particular alternative would be low. Terrestrial and aquatic wildlife habitat associated with these land uses would be displaced according to the amount of land displaced. All bypass alternatives but one would result in moderate to severe noise impacts for some receptors, although Alternative 1 would result in moderate and severe impacts to far more receptors. Implementation of a bypass alternative could result in one residential and one commercial displacement, while implementation of Alternative 1 would result in the displacement of five commercial displacements and one institutional displacement. A north bypass would reduce access to Verona Industrial Park. Alternative 1 would result in an increase in the accident rate for the facility, as well as in impacts to the Matts House historic site.

Preparation date: June 1, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STATE ROUTE 17, BYPASS EXTENSION, FAUQUIER COUNTY, TOWN OF WARRENTON, VIRGINIA: STATE PROJECT 6017-030-108, P101, R201, C501; FEDERAL PROJECT F-117-1(103). AN - 36405390; 2254 AB - PURPOSE: Implementation of highway improvements in central Fauquier County, Virginia, north of Warrenton and within the town limits is proposed. The highway improvements would begin east of Warrenton at the intersection of Route 15/29 and Route 15/29 Business and end northwest of Warrenton at Route 17. Several alternatives have been considered. These alternatives include three dual-lane designs on new alignment and an alternative that would involve widening of the existing roadway to six lanes with new intersections, as well as mass transit, rail, truck restrictions, minor improvements to the existing alignment, and implementation of a transportation management system. The dual-lane options extend 2.6 to 4.3 miles, while the option of widening the existing highway would involve 1.5 miles of road improvements. The 2.6-mile option could include depression of a portion of the highway. Noise walls could be included in the project design. Depending on the alternative considered, project cost estimates range from $18.5 million to $30.4 million. POSITIVE IMPACTS: Project improvements would dovetail with improvements of other roadways in the Warrenton area during the past five years. Both Route 17 north of Warrenton and Route 15/29 east of Warrenton were dual-laned, with the intention of connecting them to a road such as the one proposed. Truck and other through traffic, which currently must pass through the congested Warrenton commercial area, would be able to bypass the city entirely. The new road network would accommodate the ever increasing traffic in the Route 29 and Route 17 corridors. Long-term planning at the state, county, and township level would be supported. NEGATIVE IMPACTS: Depending on the alternative chosen, the project could displace up to 2 families and 10 businesses and 0.34 to 9.96 acres of wetlands. An additional crossing of the tributaries to a local reservoir project would be created, and the highway would be moved closer to the reservoir. Noise levels at various locations would increase significantly, with levels increasing by more than 10 decibels on the A-weighted scale at up to 182 locations and exceeding federal standards at up to 31 locations. Two historic properties eligible for inclusion in the National Register of Historic Places could be affected.

Preparation date: May 26, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LAKE CATAMOUNT RESORT, ROUTT COUNTY, COLORADO. AN - 36382619; 2220 AB - PURPOSE: Construction of a year-round resort associated with Lake Catamount near Steamboat Springs in Routt County, Colorado is proposed. The resort would be located in the Yampa River Valley, approximately seven miles south of Steamboat Springs. The area is accessed by County Road 18 and Colorado Highway 131, both of which are linked to U.S. Highway 40, north of Lake Catamount. Lake Catamount Joint Venture has applied for a Special Use Permit that would allow development and use of 6,600 acres of National Forest System lands located in portions of the Harrison and Green Creek drainages. Development is proposed on both public lands within the Routt National Forest and adjacent private lands. When completed, more than 2,800 acres of ski runs would be provided for a total capacity of 12,000 skiers at one time (SAOT). The project would also include construction of 16 lifts and 1 gondola through four or five development stages. Five or six lifts would be constructed during the initial stage, providing capacity for 5,000 to 6,000 SAOT. Subsequent development would be undertaken as skiing demand warranted. Integral to the project to develop National Forest System land would be a plan to develop adjacent private land located around Lake Catamount, a 495-acre artificial lake centered within the private property. This private development would include: the Founder's Lodge and a number of single-family lots and associated recreational amenities, located on the western side of the lake; Lake Village, located on the northwestern side of Lake Catamount, to include a mixture of residential and commercial uses and recreational amenities oriented to take advantage of the lake; and Mountain Village, located on the southeastern shore of the lake, to include single-family and medium-density, multifamily residential uses. Mountain Village would include 10,000 square feet of commercial development and a ski lodge containing 20,000 square feet. POSITIVE IMPACTS: Recreational development in the area would be consistent with the Routt National Forest management plan and would generally aid in providing recreational opportunities for regional residents. Local employment rolls and other positive socioeconomic indicators would increase significantly. NEGATIVE IMPACTS: Landslide hazards would affect portions of the lower slopes of the mountain where ski lifts and runs would be developed. Ski trail and lift terminal grading and road construction would expose soils to erosion and reduce the vegetative cover. Water yield for all major drainages in the area, except the Yampa Tributary, would increase. Changes in runoff could modify channel hydraulic conditions and impact channel stability at certain locations within the area proposed for development. The Danvers Creek drainage could be significantly affected. Sediment loading to Lake Catamount could increase from on-site watershed disturbance or project-created channel instability. Water quality could decline due to urban development, wastewater treatment system effluent, dredging and filling activities, and slope development. Up to 135 acres of wetlands and associated wildlife habitat could be lost. Approximately 1,950 acres of elk habitat would be lost or otherwise affected, leading to a substantial reduction in the Catamount elk herd, and the local black bear population would decline. Burning of wood in fireplaces and woodstoves would result in violation of air quality standards under certain conditions. The increase in population would reduce the quality of life for some residents and place stress on social services and the transportation system.

AN - 36398519; 2207 AB - PURPOSE: Drilling of an exploratory oil/gas well on the Custer National Forest near Red Lodge, Montana is proposed by Phillips Petroleum Company. The project would involve directional drilling of a 12,520-foot exploratory well on the Beartooth Ranger District in Carbon County. The drilling site would lie in the Ruby Creek drainage, a tributary to Clarks Fork of the Yellowstone River. More specifically, the drill site is located in the NW1/4 NW1/4 Sec 15, T9S, R20E. Access to the proposed site would involve 4.3 miles of Montana State Highway 72 south from Belfry, Montana to Grove Creek Road, an existing county road. From this point, access would head west towards the drill site, using five miles of Grove Creek Road and approximately eight miles of existing unimproved ""two-track'' roads to the Custer National Forest boundary. Access to the forest boundary would traverse lands administered by the Bureau of Land Management and land under private ownership. From the forest boundary, access would be via unimproved two-track road. To reach the drill site from this point, 0.3 miles of new road would be constructed. Phillips proposes to construct a 1.7-acre drill pad. POSITIVE IMPACTS: The well would provide information on the potential of the area for economical extraction of oil and gas from subsurface reserves located within the area. Drilling and roading activities would increase the local employment pool slightly. NEGATIVE IMPACTS: Disturbance associated with this alternative would affect 21.3 acres for road reconstruction, 1.5 acres for new road construction, 1.7 acres for the drill pad, and 0.8 acres of cut and fill slopes and topsoil stockpiles associated with the drill site. Total area disturbed would be 25.3 acres. Road construction and reconstruction could increase erosion and sedimentation of Ruby and Gold creeks and would result in disturbances of vegetation, timber, and range resources, as well as associated wildlife habitat and visual and recreation resources. Recreation-related industries could be adversely affected.

Preparation date: May 19, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - I-5 WIDENING AND INTERCHANGE IMPROVEMENTS IN SAN DIEGO, CALIFORNIA (BETWEEN I-5 AT GENESEE AVENUE, I-805 AT MIRA MESA BOULEVARD, AND I-5 AT DEL MAR HEIGHTS ROAD). AN - 15225800; 2236 AB - PURPOSE: Widening of Interstate 5 (I-5) and improvements to interchange access along that freeway in the city of San Diego, San Diego County, California are proposed. The project would involve seven miles of interstate highway between I-5 at Genesee Avenue, I-805 at Mira Mesa Boulevard, and I-5 at Del Mar Heights Road. The existing I-5 freeway, an eight-lane facility, had an average daily traffic volume of approximately 200,000 vehicles. Traffic demand forecasts predict continued increases in traffic volumes. The project would involve construction of additional traffic lanes and improved interchanges along I-5. Two design alternatives are under consideration. The dual freeway design variation would involve widening the existing 8-lane freeway to 10 lanes between Carmel Mountain Road and Carmel Valley Road; constructing 6 new freeway lanes outside of and separated by a media barrier from existing I-5 between the I-5/I-805 junction and Carmel Valley Road; widening the existing 8-lane I-5 freeway to 12 lanes between Carmel Valley Road and Del Mar Heights Road; constructing I-5 direct connectors northbound to eastbound, and westbound to southbound, at Carmel Valley Road (future Route 56); constructing direct connectors at the I-5/I-805 junction between the new separated freeway lanes and existing lanes; constructing a partial interchange on Carmel Valley Road at El Camino Real; and widening ramps, adding auxiliary lanes, and other improvements on I-5 and I-805. The main lane widening design variation would involve widening the existing 8-lane I-5 freeway to 14 lanes between I-5/I-805 and Carmel Valley Road and to 12 lanes between Carmel Valley Road and Del Mar Heights Road; constructing I-5 direct connectors northbound to eastbound, and westbound to southbound, at Carmel Valley Road; constructing direct connectors at the I-5/I-805 junction; constructing a partial interchange on Carmel Valley Road at El Camino Real; and modifying ramps, adding auxiliary lanes, and other improvements. The estimated costs of the dual freeway and main line widening variations are $128.0 million to $139.2 million and $76.5 million, respectively. POSITIVE IMPACTS: Implementation of the project would alleviate traffic congestion along the corridor, meet regional transportation needs, and support economic development within the city and county. The project would address undesirable weaving conditions at I-5/I-805 as traffic merges, slow moving truck traffic on the northbound I-5 grade between Carmel Valley Road and Del Mar Heights Road, narrow shoulders on I-5 bridges over the Atchinson Topeka and Santa Fe Railroad, an embankment failure on a portion of I-5, and a major drainage problem caused by accumulated sediment in culverts under I-5 at Carmel Valley Creek. NEGATIVE IMPACTS: The dual freeway design would displace 71 to 82 acres of land for rights-of-way acquisition, while the main line alternative would displace 47 acres of land. Land displaced would include wetlands associated with Los Penasquitos Creek and Carmel Valley Creek. Up to 2.2 acres would be removed from Los Penasquitos Canyon Reserve. Placement of 7,000 to 15,000 feet of retaining walls would mar area aesthetics, and significant cut and fill slope development would alter topography along the corridor. The main line design may not provide an acceptable level of service for peak period travel. Existing noise levels, which exceed federal standards, would be increased for numerous receptors.

AN - 36409572; 2263 AB - PURPOSE: Upgrading of the Metropolitan District Commission (MDC) wastewater management systems, including sewer interceptors, wastewater treatment facilities, and sludge disposal facilities, in Boston, Massachusetts is proposed. The final environmental impact statement (EIS) of December 1985 recommended treatment of wastewaters from the entire Metropolitan Sewerage District service area at a centralized location at the Deer Island Plant. This supplement to the final EIS on the upgrading project addresses the clean-up of Boston Harbor. More specifically, the document addresses the long-term (1995-2020) treatment, transport, and disposal of ""residuals'' from the new Massachusetts Water Resources Authority (MWRA) wastewater treatment system. Residuals include grit, defined as heavy particles settling from the wastewater stream; screenings, defined as large objects screened from the wastewater; scum, defined as floating material skimmed from the surface of the wastewater; and sludge, defined as solids settling from the wastewater during treatment. Six sites and six techniques of disposal are considered. The MWRA Board has chosen, as its recommended plan, a combination of heat drying and composting of sludge at the Quincy Fore River Staging Area. Quincy has a population of approximately 85,000 and lies approximately 10 miles south of Boston. The staging area is located in the southern portion of Quincy along the Weymouth Fore River, which abuts the site on the east. POSITIVE IMPACTS: The Quincy site would offer an environmentally acceptable means for transfer, dewatering, heat drying, and composting of residuals. NEGATIVE IMPACTS: Significant odor impacts could result from the composting operation, particularly due to the proximity to potential receptors. Noise impacts would result from residuals processing and handling at the site; these noise impacts would be minimal at the heat-drying and off-loading facilities due to the distance of the facilities from receptors. Operating noise at the compost facility can generally be mitigated by designing low-noise generating mechanical systems and by minimizing building openings. Materials handling activities, particularly at the compost facility, could also generate noise. Truck traffic would increase in the Quincy area, and the traffic could overlap truck traffic generated by the Deer Island treatment plant. Developments at the Quincy site would result in damage to a district eligible for inclusion on the National Register of Historic Places.

AN - 36382664; 2248 AB - PURPOSE: Construction of a 12-mile roadway in the cities of Independence, Kansas City, and Sugar Creek, and unincorporated Jackson County, Missouri is proposed. The expressway would begin at the Front Street interchange on Interstate 435 (I-435) in Kansas City and extend easterly along the south side of the Missouri River. The corridor would pass through the vicinity of Amoco's Sugar Creek Refinery and continue to a major interchange with Missouri 291 (M-291). The alignment would then continue east of M-291 to the vicinity of the Missouri Pacific Railroad and turn south to an interchange/intersection with U.S. 24 in Independence. Of the three alternatives under consideration, the preferred alternative would pass farthest to the south of the KCP&L and Mobay industrial sites on the west end of the project corridor. It would remain in the Missouri River floodplain until a point east of M-291. The alignment would climb the river bluff in the vicinity of the Santa Fe Railroad tracks and River Bluff Park, would parallel Union School Road to a point near the Missouri-Pacific Railroad tracks where the alignment would turn southerly, and generally parallel the railroad to an intersection with U.S. 24. The project would feature four 12-foot-wide lanes, with 10-foot outside and 4- to 6-foot inside shoulders. The median width would be 10 to 60 feet, and a 30-foot lateral clearance zone would be provided. Design speed would be 60 miles per hour. The estimated cost of the project is $60.6 million. POSITIVE IMPACTS: The facility would serve the area immediately south of the Missouri River in the eastern portion of the Kansas City metropolitan area. Access to heavy industrial sites, which dominate the area, would be improved significantly. Reliance on rail transport by the affected industries would decline. Access for residential development in the area would also be improved. NEGATIVE IMPACTS: Approximatley 317.4 acres of rights-of-way would be developed, including 156.2 acres of prime farmland. One farm and two businesses would be displaced. Vehicular traffic on the new facility would increase noise levels within the corridor. The project would take 8.14 acres of River Bluff Park and a portion of the historic Lewis and Clark Trail. An important wintering area for wildlife, including eagles, would be impacted. Sixteen archaeological sites lie within the broad project corridor; nine would be impacted by the proposed expressway. The highway would pass through an area containing numerous hazardous waste disposal sites.

Preparation date: May 12, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GRAYS HARBOR, WASHINGTON NAVIGATION IMPROVEMENT PROJECT (FINAL SUPPLEMENT I TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF SEPTEMBER 1982). AN - 15225832; 2271 AB - PURPOSE: Widening and deepening of the existing federal deep-draft navigation channel at Grays harbor on the Washington coast is proposed. This final supplement to the final environmental impact statement (EIS) of September 1982 updates the description of impacts that are expected to result from the project. The existing channel extends from the Pacific Ocean through Grays Harbor up the Chehalis River to Cosmopolis. The recommended plan would involve widening and deepening 23.5 miles of existing channel from the ocean bar to Cosmopolis; expanding the Cow Point and Elliott Slough turning basins; deepening local ship berthing; modifying the Union Pacific Railroad bridge at Aberdeen by replacing the existing swing-span with a lift-span bridge; modifying fendering around the north pier of the Highway 101 bridge in Aberdeen; designation of two ocean-dredged material disposal sites; removing two old highway bridge piers on the north bank at a point 1,500 feet upstream of the Highway 101 bridge; and relocating utility lines under the channel in the Aberdeen area. The portion of the channel from South Reach to Cosmopolis is presently maintained annually; the entrance reach and bar are self-maintaining as a result of jetty systems. The channel would be dredged to the following dimensions: the ocean bar, 46 feet deep and 1,000 feet wide; the harbor entrance, 46 to 36 feet deep and 600 to 1,000 feet wide; the outer harbor, 36 feet deep and 350 feet wide; and the inner harbor, 36 feet deep and 250 to 350 feet wide. During the first year following channel widening and deepening, new maintenance dredging of 1.17 million cubic yards (c.y.) would be required over and above the 1.68 million c.y. of material now being removed annually. Over the following four years, additional dredging would decrease to 770,000 cubic yards. Construction dredging would be accomplished by hopper, clamshell, and cutterhead-suction/pipeline dredges, with disposal of dredged material at two ocean, two harbor open-water, and two confined disposal sites. Maintenance dredging would be performed by hopper and clamshell dredges, with disposal at one ocean and two harbor open-water sites. The project would include components to mitigate damage to Dungeness crab fishery losses and losses of salmon habitat. The estimated cost of the project is $70.0 million, and the benefit-cost ratio is estimated at 1.7. POSITIVE IMPACTS: Dredging to enlarge the navigation channel would improve safety within the harbor and reduce the potential for vessel-bridge collisions, reduce transportation costs for goods accommodated by the harbor, and reduce the existing potential for undermining the South Jetty. NEGATIVE IMPACTS: Dredging and disposal activities would result in a loss of 77,600 harvestable crabs during construction and 204,300 harvestable crabs during 50 years of incremental future operations and maintenance. The project would also adversely affect approximately two acres of subtidal habitat used by salmonids. Dredging and disposal operations would result in temporary turbidity and destruction of benthos.

AN - 36405647; 2247 AB - PURPOSE: The construction of a limited-access freeway to connect Interstate Route 70 (I-70) and Missouri Route 94 through Saint Charles County, Missouri, is proposed. The 7.75-mile facility would provide a 36-foot-wide pavement in each direction, separated by a 22-foot-wide median and a concrete median barrier. Four access points are proposed. More specifically, access to the freeway would be provided via interchanges at Route 94 in Saint Charles, Elm Street, Harry S. Truman Road, and I-70. Service roads and outer roadways would also be provided. The project would begin at Route 94, continue northwest across Boschertown Road, curve west between Elm Point Road and Mueller Road as it enters the Mississippi River floodplain, continue west within the floodplain and south of the Union Electric substation and an associated overhead powerline, turn southwest near Hayford Road (now abandoned) to cross the Norfolk Southern Railroad, and reenter the uplands north of the I-70 weighing stations. The estimated cost of the preferred alternative, including rights-of-way acquisition, construction, incidentals, and inflation, is estimated at approximately $101.4 million. POSITIVE IMPACTS: The freeway would reduce congestion on existing highway facilities in the area, reducing travel times and costs as well as pollution. The economic bases of Saint Charles County and the cities within the highway corridor would be improved substantially. Adverse travel conditions on local highway connectors would improve, and public safety would be enhanced. NEGATIVE IMPACTS: The rights-of-way requirements would result in the displacement of 249.7 acres of prime and unique farmlands and 5.6 acres of farmlands of statewide or local importance; the proportion of farmlands to be impacted in the county would be 0.182 percent. Three households, housing nine persons, would be displaced; these households would include two farmsteads near the weighing station at the western end of the project. The project would traverse 100-year floodplain land and associated wetlands. The freeway would result in the development of natural land, exacerbating the effects of the project on natural resources directly affected by construction. Two archaeological sites and two sites of historic architectural significance would lie within the highway corridor. Additional sites could be identified.

Techniques (including equipment design , construction, and installation) for assessing wetland soil attributes have been developed that allow direct field measurements of soil O2 content, oxidation-reduction potential, water-table depth, and presence of ferrous iron. Soil O2 content is measured from diffusion chambers with a specially fitted polarographic probe. Redox potential is measured with permanently installed platinum electrodes and a voltmeter. Determination of water-table depth may require piezometers in addition to unlined observation wells. The presence of ferrous iron can be detected with alpha,alpha,-dipyridyl and indicates anaerobic conditions, although interpretation and extrapolation of results must be carefully made. These parameters are particularly diagnostic and results of field studies reveal their dynamic nature and utility in wetland delineation efforts.

AN - 36404761; 2272 AB - PURPOSE: Construction of a dam and reservoir on Savery Creek in south-central Wyoming is proposed to provide for the municipal, agricultural, and industrial water supply needs of the Little Snake River basin. Savery Creek is a tributary of the Little Snake River. This draft supplement to the draft environmental impact statement of January 1988 contains a revision of the purpose and need statement of the project and a mitigation plan developed jointly by the Wyoming Water Development Commission, the Wyoming Game and Fish Department, and the U.S. Fish and Wildlife Service. The dam, which would be located approximately 8.5 road miles north of the town of Savery on a constricted portion of a narrow canyon just below the mouth of Little Sandstone Creek, would impound a reservoir of approximately 52,000 acre-feet and have a surface area of 960 acres. The dam would be approximately 200 feet high and 3,100 feet long and would create a reservoir extending 7.7 miles upstream on Savery Creek, 1.9 miles upstream on Big Sandstone Creek, 2.3 miles upstream on Little Sandstone Creek, and 0.1 mile upstream on Hell Canyon Creek. The zoned earthfill dam would have a crest width of 30 feet, a crest elevation of 6,985 feet above mean sea level (msl), and a fill volume of 6.125 million cubic yards (mcy), including 1.43 mcy of impervious material, 1.19 mcy of granular material, 3.38 mcy of random fill, and 125,000 cubic yards of riprap. Borrow material for the dam would be taken from alluvial and colluvial deposits on the right side of the reservoir below high water level and the Savery and Little Sandstone creek valley bottoms. The long ridge that narrows the canyon would form the left abutment of the dam; the right abutment would be a steep slope varying from 40 degrees to 70 degrees. The project's hydraulic works would consist of an ungated chute-type spillway on the left abutment and a regulated low-level tunnel outlet in the left abutment. The upstream slope of the dam would be protected from wave erosion by riprap. The pool elevation would be 6,932 feet above msl. The normal minimum water level would be 6,800 feet above msl, while the normal high water level would be 6,932 feet above msl. Dead storage would be 100 acre-feet; live storage would be 52,000 acre feet; and surcharge storage would be 21,000 acre-feet. Agricultural releases from the reservoir would be limited to providing a supplemental supply equal to 0.5 cubic feet per second (cfs) per 70 acres per year. Flows in Savery Creek below the dam would be maintained at not less than 24 cfs. The overall project would cover 4,350 acres of federal and private lands. Environmental mitigation measures would include the purchase of a riparian rehabilitation easement along Savery Creek, assurance of minimum releases for Savery Creek, construction of barriers to prevent upstream movement of fish species that would impact Colorado River cutthroat trout, and maintenance of a minimum reservoir pool of 10,400 acre-feet. The dam and reservoir would lie, for the most part, on private land. Three construction seasons would be anticipated. POSITIVE IMPACTS: Reservoir waters would supply the Little Snake River basin with a firm annual yield of 20,000 acre-feet of water for industry, an average annual yield of 12,000 acre-feet of water for agriculture, and an average annual yield of 200 acre-feet of water for municipal use. Wyoming requirements of the Upper Colorado River Basin Compact would be met. Environmental mitigation measures would enhance fishery and other riparian resources within the basin. NEGATIVE IMPACTS: The impoundment would inundate 960 acres of wildlife habitat, including 397 acres of riparian cottonwood woodlands, 42 acres of willow shrublands, 37 acres of alder shrublands, 339 acres of wet meadows, and 145 acres of upland vegetation. In addition, the reservoir would inundate 12 miles of flowing streams. Land used for cattle grazing and other agricultural purposes would be lost. Archaeological and historical remains not protected or recovered would be subject to inundation, erosion, and vandalism. Seasonal water level fluctuations would result in exposure of mudflats during the summer and other dry periods. The visual aspect of the remote stream area would be altered. Discharge of sediment-free water would result in scouring effects downstream of the reservoir outlet. The total stream flow would be depleted by 13,394 acre-feet per year or approximately 4.0 to 9.2 percent. Natural material obtained from borrow sites would be lost, and mineral exploration would be precluded in the area of the dam and related facilities and would be rendered more difficult in the reservoir area.

AN - 36409593; 2264 AB - PURPOSE: Maintenance dredging and clearing by removing sediment and riparian vegetation from the San Joaquin River from Friant Dam near Fresno to Stockton, California, a distance of approximately 225 miles, are proposed. The purpose of this revised draft environmental impact statement is to document that the project's environmental impacts have been analyzed and mitigation measures considered in relation to negative impacts of the proposed actions. Approximately 135 acres of riparian vegetation, a seven-mile section of false bamboo (50 acres), and 1.23 million cubic yards of sand would be removed from the floodplain and river channel and deposited on the landside of the levees or hauled to local disposal sites. Approximately 30,000 tons (8,900 linear feet) of riprap would be placed on portions of the Middle River where unstable banks are revealed by the removal of false bamboo and sediments. The project would include the removal of false bamboo that is interspersed with elderberry shrubs adjacent to Middle River. Worksites have been selected to provide the greatest hydraulic flood control benefit while incurring the least environmental damage. Disposal of gravels, sands, and debris would be performed away from sensitive natural areas to avoid or reduce natural resource impacts. These disposal sites have been coordinated with landowners to avoid structures such as pumps and concrete drains and with resource agencies to avoid significant resources. Mitigation measures would include 133 acres of revegetation, 300 acres of wildlife habitat enhancement, and seven acres of wetland development. Easements would be acquired on 485 acres. The estimated total first cost of the project is $15.6 million. POSITIVE IMPACTS: Channel clearing would reduce flood levels within the levees in the vicinity of the selected sites and nearby seepage problems on the land side of the levees. Agricultural efficiency would be increased significantly. In the long run, habitat for the valley elderberry longhorn beetle, a threatened species, would be enhanced. NEGATIVE IMPACTS: Removal of riparian vegetation would result in the loss of associated habitat. Increased water turbidity would disrupt fisheries habitat. Work in the Middle River reach would result in the loss of some habitat of the valley elderberry longhorn beetle. Certain other endangered species could be affected; studies will be made concerning these species.

Preparation date: April 26, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DIAMOND FORK POWER SYSTEM, BONNEVILLE UNIT, CENTRAL UTAH PROJECT (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1984). AN - 36382819; 2208 AB - PURPOSE: Development of a power system, to be known as the Diamond Fork Power System, is proposed as a component of interrelated systems in the Central Utah Project's Bonneville Unit. The Diamond Fork System, in north-central Utah, would effect a transbasin diversion of water from the Uinta Basin of the Upper Colorado River Basin to the Bonneville Basin of the Great Basin. Most of the system facilities would lie within Utah County, but a small portion at the upper end of the project's structures would be in Wasatch County. The system would be constructed in the Diamond Fork and Sixth Water drainages in the Uinta National Forest of the Wasatch Mountain range. Sixth Water is a tributary of Diamond Fork, which is a tributary of the Spanish Fork River. The transbasin diversion would provide water for the Municipal and Industrial System of the Bonneville Unit and for supplemental irrigation service in the Spanish Fork area of south Utah County. Water would also be provided for the Irrigation and Drainage System of the Bonneville Unit. The transbasin diversion would descend from the enlarged Strawberry Reservoir in the Uinta Basin to the confluence of Diamond Fork and the Spanish Fork River in the Bonneville Basin through a system of tunnels, pipelines, and a powerplant. The system would facilitate an annual average transbasin diversion of between 101,600 acre-feet and 142,500 acre-feet of Bonneville Unit water and 56,700 acre-feet of Strawberry Valley Project water from the Uinta Basin to the Bonneville Basin. This supplement to the final environmental impact statement (FEIS) of October 1984 discusses the proposed reduction in the size of the power system design. Changes in the market situation make the plan submitted in the FEIS no longer practical. Three alternatives presented in this supplement would provide from 68.5 to 70.0 megawatts (MW) of installed generating capacity compared to the 166.2-MW system described in the FEIS. From 3.0 to 18.0 MW would be needed to meet the requirements of the Bonneville Unit, depending on the alternative selected. Facilities added to the FEIS plan under the new plan would result in the development of the Syar Powerplant and Dam, Corona Aqueduct, Sixth Water Powerplant and Dam, and Dyne Aqueduct and Powerplant. POSITIVE IMPACTS: Development of water and energy sources through the plan would fulfill the project objectives of supplying immediate and projected needs for the rapidly growing population along the Wasatch Front. Some project energy would be used to pump water for the Central Utah Project, while the remainder would be marketed for commercial use throughout the Colorado River Storage Project marketing area. In addition to providing water and power, the system would open up recreational and fishing opportunities in the area. NEGATIVE IMPACTS: Project development would destroy 98 to 447 acres of vegetation permanently and 23 to 169 acres of vegetation temporarily. Maximum stream flows in Sixth Water Creek and Diamond Fork between Last Chance Powerplant and Monks Hollow Reservoir would be moderately to significantly less than under the 1984 FEIS plan. Water temperature stratification within the Strawberry Reservoir would be altered. Habitat, including that of endangered species, would be displaced, and grazing capacity in the area would decline; the cost to grazing permittees would increase.

AN - 36407988; 2188 AB - PURPOSE: Restoration and enhancement of Batiquitos Lagoon as a biological and physical system is proposed. The lagoon lies in the city of Carlsbad in northern San Diego County, California. More specifically, the lagoon is situated 90 miles south of Los Angeles and 35 miles north of San Diego. The enhancement project would involve dredging to produce shallow subtidal and intertidal habitats and maintaining an open ocean inlet with sufficient tidal prism to ensure flushing and good water quality throughout the lagoon. Key construction components of the project would include: (1) physical reconfiguration of the lagoon through dredging /excavating and contouring to restore tidal inflows; (2) development of a tidal inlet structure; (3) construction of a freshwater marsh; (4) creation of new shallow subtidal and intertidal habitats; (5) construction of nesting sites for the California least tern; and (6) nourishment of ocean beaches at Batiquitos Lagoon and Encinas Creek with sands mined from the Central basin of the lagoon as part of the overall dredging and disposal plan. Beach nourishment would involve 114,000 cubic yards of sand at the Batiquitos beach (Ponto Beach) and 2.1 million to 3.1 million cubic yards of material at the Encinas Creek site. POSITIVE IMPACTS: Important existing biological values within the lagoon would be protected and certain biological values would be created or enhanced. Tidal influence would be restored to the lagoon. The project would mitigate damage caused by landfills in San Pedro Bay associated with the Port of Los Angeles 2020 Plan. Fish, waterfowl, and other wildlife habitat values gained from the enhancement project would be used to offset the habitat values lost as a result of landfill projects within the Los Angeles Harbor District. Salt marsh habitats, flood control, and health and safety within the area would be enhanced as well. Beach nourishment would increase the area's recreational value. A net contribution to the littoral drift of 55,000 cubic yards would increase sand flow nourishment to beaches south of Carlsbad. NEGATIVE IMPACTS: Dredging and placement of beach nourishment would result in temporary turbidity within the lagoon and at the beach sites, respectively, and dredging could result in damage to archaeological and paleontological sites. Construction of the tidal inlet structure would also result in short-term disruption of bottom sediments, reducing water quality.

AN - 36406721; 2176 AB - PURPOSE: Construction of a Northern Outer Bypass in Horry County, South Carolina is proposed. The new 30-mile highway would extend eastward from U.S. Route 501 between the town of Aynor and the city of Conway, proceed around the north side of Conway and end on U.S. Route 17 in the vicinity of the city of North Myrtle Beach. Design features would include four lanes from U.S. Route 501 to S.C. Route 95 and six lanes from S.C. Route 905 to U.S. Route 17, 12-foot-wide travel lanes, 10- to 12-foot safety shoulders, and an 80- to 104-foot graded median within a general rights-of-way width of approximately 260 feet. The rights-of-way would be able to accommodate expansion of the facility to six and eight lanes in the future if necessary. Rights-of-way requirements would be greater at interchanges. A high-level bridge would be provided over the Intracoastal Waterway. Bridges would also be provided over major stream crossings, at major crossroads and railroads, and at other locations where necessary to accommodate soil and hydraulic conditions. Interchanges would be provided at U.S. Route 501, S.C. Route 319, U.S. Route 701, S.C. Route 905, S.C. Route 90, and U.S. Route 17. The diamond interchange configuration would be used at the less heavily travelled interchanges, while directional ramps and loops would be used at the more heavily travelled interchanges. Eight alternative alignment combinations are under consideration. The estimated costs of the projects range from $28.6 million to $31.7 million, depending on the alternative combination chosen. POSITIVE IMPACTS: Access to beach resort areas in the vicinity of the Grand Strand would be improved. Additional regional traffic volumes expected in Horry County would be accommodated. Internal circulation conditions in Conway and along the Grand Strand would be eased. An additional emergency evacuation route from the coast would be provided for hurricane relief. The highway design would preserve the rural freeway appearance, eliminate the need for costly median barriers, eliminate the need to acquire additional rights-of-way in the future when it would be more difficult and costly, and preclude additional impacts associated with expanding rights-of-way limits. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 5 to 13 homes, 2 to 14 businesses, 215 to 300 acres of wetlands, and 169 to 438 acres of farmlands. Noise levels would exceed federal standards at 8 to 28 sites. Highway development would affect three to five archaeological sites potentially eligible for inclusion in the National Register of Historic Places and four to nine additional archaeological sites, the status of which are as yet undetermined.

AN - 36382896; 2192 AB - PURPOSE: Implementation of commercial light draft navigational improvements at Kahului, Maui, Hawaii is proposed. The project study area is located within the Kahului Deep Draft Harbor on the north coast of the island of Maui. The project would involve development of a 130-foot breakwater with a crest elevation of nine feet above mean lower low water; a 100-foot-long by 100-foot-wide by 8.5-foot-deep turning basin; a 1,030-foot-long entrance channel with a width of 50 feet and a depth of 9.5 feet; and a two-lane boat launch ramp. Channel and turning basin development would require dredging of 13,200 cubic yards of material. The estimated cost of the project is $2.047 million, and the benefit-cost ratio is estimated at 1.8. POSITIVE IMPACTS: Harbor facilities would provide for safe navigation and launch /recovery of vessels and could promote the growth of related public facilities and services. Recreational activities, including fishing, would be supported and promoted. Commercial fishing would also be enhanced. Employment and other economic indicators would be enhanced. The breakwater would provide habitat for fish and invertebrates. NEGATIVE IMPACTS: Commitment of 5,500 tons of quarried stone would be required for breakwater development. Approximately 0.1 acre of terrestrial habitat would be modified due to ramp construction. Dredging and possible blasting would kill some invertebrates and fish. Harbor improvements would constitute visual intrusions upon the landscape.

Preparation date: April 17, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GARY MARINA, LAKE COUNTY, INDIANA. AN - 36382578; 2163 AB - PURPOSE: Development of a marina on Lake Michigan in the city of Gary, Lake County, Indiana is proposed. The project, to be sponsored by the city of Gary, would be located between the USX (formerly U.S. Steel) breakwater to the west and Marquette Park to the east. The preferred 220-acre site would lie near lands administered by the Indiana Dunes National Lakeshore, which encompasses 14,000 noncontiguous acres. The 1,100-slip marina would be accessed via a new road constructed on the existing roadbed of the Indiana Harbor Belt Railroad. Supporting marine services would include diesel and gas fuel facilities, retail sales serving boating activities, boat /motor maintenance and service facilities, dry storage provisions, and public use areas. Marina design would also support nonboating recreational activities; both boating and nonboating activities would be supported by parking facilities, rest rooms, bathhouses, and other services. In addition, the site would support development of associated residential and commercial uses. Development of offshore facilities would involve dredging and filling to create a small boat harbor and sites for land-based facilities and construction of a steel-sheet breakwater. The harbor would have an interior depth of 8 to 10 feet, while the marina entrance would have a depth of 12 feet. The moorage system would be either a fixed-pier or floating dock arrangement. A launching ramp and a service island would also be provided. Construction would be phased between 1992 and 2004. POSITIVE IMPACTS: Marina development would meet the regional demand for recreational boating and lakefront facilities for public use in the city of Gary. One site would support the development of additional housing and business uses. A new opening to be made in the USX breakwater would enhance water circulation and provide access to a sheltered sedimentary environment for fish. NEGATIVE IMPACTS: Dredging would result in temporary turbidity and alteration of bottom topography. Some trace metals could be released during construction, but the metals would not be highly soluble.

Preparation date: April 17, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GEORGIA PROJECT MLP-813(1): RELOCATION OF EXISTING U.S. 27 ON NEW LOCATION NEAR COUNTY ROAD 144 AND S.R. 2, WALKER AND CATOOSA COUNTIES, GEORGIA. AN - 36402336; 2170 AB - PURPOSE: Relocation of U.S. 27 to a corridor outside the western boundary of the Chickamauga-Chattanooga National Military Park in Walker and Catoosa counties, Georgia is proposed. The new facility would extend northward 5.1 miles from a point on U.S. 27 near County Road 144 to the intersection of State Route (S.R.) 27 and U.S. 27. The typical cross-section would feature four 12-foot travel lanes, separated by a 44-foot-wide grassed median within an overall rights-of-way width of 200 to 400 feet. S.R. 2 would be intersected via a trumpet interchange. Three alternative alignments are under consideration. All alternatives would follow a common alignment from existing U.S. 27 to a point approximately 150 feet north of the proposed crossing of Long Hollow Road. All alternatives would intersect most local streets at-grade. Overpasses would be provided at two crossings of the Central of Georgia Railroad and at the crossing of Old S.R. 2 (McFarland Gap Road). Access would be provided to and from McFarland Gap Road via a short access road. Regardless of the alternative chosen, a short relocation of Long Hollow Road would be required to provide a more efficient intersection with the proposed highway. Little Road/County Route 297 would be relocated to pass under the bypass highway to avoid the need to redirect current neighborhood traffic patterns. The estimated cost of the project is $30.0 million. POSITIVE IMPACTS: Removal of the facility from the park would reduce travel time and improve vehicle efficiency for commuters and local users. Access for emergency vehicles would improve significantly along the project corridor. Economic activity along the new corridor could be boosted, depending on local zoning regulations. NEGATIVE IMPACTS: One wetland site would be impacted, and approximately 60 acres of farmlands would be displaced. Some build alternatives would require the use of land from the Chickamauga-Chattanooga National Military Park. Rights-of-way requirements would result in displacement of 36 to 80 owner-occupied residential units and 2 to 3 tenant-occupied units. Depending on the alternative chosen, noise levels would exceed federal standards at 17 to 20 residences, and 74 to 88 sites would be affected by substantial increases in noise levels. The facility would bypass the business area of Fort Oglethorpe, resulting in the loss of commerce. LEGAL MANDATES: Department of Transportation Act of 1966 (49 U.S.C. 1651 et seq).

AN - 36398089; 2154 AB - PURPOSE: Multiple mining operations in the Wrangell-St. Elias National Park and Preserve of Alaska are assessed. The assessment is required by the U.S. District Court's (District of Alaska) final judgment and injunction of March 3, 1988 (Civil Case J85-009). Currently, 457 unpatented and 466 patented mining claims are recorded within the park/preserve. Under the proposed action, mining proposals would be reviewed using a quantitative evaluation of cumulative impacts and resource protection goals. More specifically, the evaluations would be directed at mining activities in the Kantishna Hills study area of the park and preserve. This action coincides with the need to evaluate the minerals management programs in the Yukon-Charley Rivers and Denali National Park System (NPS) units to provide for adequate resource management and protection. Issues identified during the scoping analysis include hydrologic changes, fisheries habitat, fishes, water quality, impacts on wetlands, aquatic ecosystem integrity, long- and short-term impacts, nonmining usage of patented claims, reclamation, wildlife habitat (grizzly bear, moose, Dall sheep, caribou, and wolves), threatened and endangered species, criteria for cumulative effects analyses, impact thresholds, magnitude of impacts, economic impacts, access, impacts of access, subsistence activities, heavy metals contamination, abandoned mine lands, impacts on scenic values, administrative costs for mining claims, acquisition costs of mining properties, and wilderness values. For purposes of analysis, a probable mineral development scenario was developed and applied for each alternative scheme to project environmental impacts. The scenario predicts where and to what extent future mining activity might reasonably occur in the park over the next 10 years. The scenario does not represent an NPS proposal, nor does it suggest levels of mining activity acceptable to NPS. Under the proposed scheme, NPS would review plans of operations on a comprehensive basis and prepare environmental documents. Target resources would be identified and used as the focal points for evaluating the effects of proposed mining activity. Determinations of site-specific and cumulative mining impacts would be made quantitatively where adequate resource information was available, using resource protection goals as one evaluative tool. Resource protection goals would be established for aquatic resources, grizzly bear habitat, moose habitat, Dall sheep habitat, and caribou habitat. If the resource protection goal for any target resource could not be met because of the potential effects of a proposed mining operation, that proposal could be denied unless mitigation could reduce the magnitude of the effects within the resource protection goal or otherwise protect resource values, or unless other circumstances would justify approval. Resource protection goals would not be established initially for wetlands, wolves, visual quality, subsistence activities, recreation, wilderness values, the local economy, and cultural resources. POSITIVE IMPACTS: Mining activities would contribute to local, regional, and national economies and help the nation maintain its self-sufficiency in mineral resource availability. Environmental requirements associated with analyses would prevent extensive damage to target resources. NEGATIVE IMPACTS: Some impacts would be expected from surface mining activities. Claims taken to patent would not be protected from disruptive, and potentially damaging, nonmining uses.

Preparation date: April 5, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 199 FROM ROUTE 5 IN JAMES CITY COUNTY TO INTERSTATE 64 IN YORK COUNTY, VIRGINIA. AN - 36407404; 2177 AB - PURPOSE: Construction of a four-lane, divided, controlled-access highway within the counties of James City and York, Virginia is proposed. The southern project terminus would lie within the vicinity of the intersection of completed Route 199 and Route 5 in James City County. The northeastern project terminus would lie in the vicinity of the existing Interstate 64 (I-64) interchange with Route 646. Forestland currently predominates the land to be traversed, although land uses include residential and commercial development as well. Each alignment alternative would provide access at Routes 5, 615, 612, 60, 646, and I-64. The highway would provide interchanges at Route 60 and I-64. The remainder of the access points would initially be at-grade; however, sufficient rights-of-way would be acquired to accommodate the construction of interchanges at these locations when traffic volumes demand such improvements. Initially, an interchange at I-64 and an interchange at Route 60 would be provided; ultimately interchanges would be provided at Routes 615, 612, 646, and 658. A minimum rights-of-way width of 200 feet would be acquired. Construction of this 7.5-mile project would occur primarily on new alignment. The facility would be designed to accommodate from 12,000 to 21,000 vehicles per day in the year 2010. The estimated cost of the project is $27.0 million. POSITIVE IMPACTS: Construction of the highway would increase the traffic carrying capacity of the existing highway system, tie together the existing road system to make it more functional, facilitate the movement of emergency and rescue equipment, and improve access to several schools. The project would help implement the transportation planning goals of James City County, York County, the Metropolitan Planning Organization, and the Peninsula Planning District Commission. Congestion caused by the passage of nonlocal traffic through Williamsburg would be reduced. Traffic volumes on Route 60 would decline, and access to the Warhill Tract and tourist support facilities along Route 60 and to the growing residential area of James City County west of Williamsburg would be improved. NEGATIVE IMPACTS: Development of highway rights-of-way would result in the displacement of 13 families, 146.8 acres of forestland, 28 acres of farmland, and 12.2 acres of wetlands. Wetlands would be lost within the drainages of Mill Creek, Chisel Run, Long Hill Swamp, and Powhatan Creek. One historic site and five prehistoric sites could be affected. Highway alignment would have to be revised to prevent damage to a colony of small-whorled pogonias, a federally listed endangered plant species.

This value is summarized by the net present value of all present and future production. Change in asset value, depreciation or appreciation, results from both changes in the economic value of each unit of production and the asset's physical productivity. A theory of depreciation expressing this approach is derived from first principles of engineering economics. The theory is illustrated fro the case of water resource reservoirs.

The test design used a factorial screening matrix with two concentrations of metals (As-Cr-Pb, 50 and 10 microgm/L; Cd, 10 and 2 microgm/L), pH (5.8 and 7.7), and total organic carbon (natural and natural plus 5 mg/L humic acid) as variables. Samples containing well casings and controls without pipe sections were run as duplicates. Aliquots were removed from all of the solutions after 0.5, 4, 8, 24 and 72 hours. Aqueous metal concentrations were determined by graphite furnace atomic absorption spectroscopy. The results showed PTFE to have no significant influence on the metals monitored under any of the groundwater conditions. Metal concentrations in groundwater exposed to SS316 and SS304 had large random variances believed to be caused by surface oxidation of the stainless steel, PVC had a more active surface than PTFE in terms of both sorption of Pb and release of Cd.

In addition, it is necessary for the work to be coordinated around scheduled lock openings, and all ancillary lock equipment must be maintained in an operational condition. During this study, operational and design criteria were developed to serve as the basis for design. A number of repair concepts were identified that satisfied the criteria. Schedule and cost estimates were prepared for the various concepts that served as the basis for selection of a preferred concept. An installation procedure using a cofferdam was selected as the preferred repair method. The design included the preparation of drawings and specifications for the repair of a generic lock to demonstrate the various aspects of the repair procedure. Cost and schedule assessments were part of this work. The results of this developmental effort suggest that it is feasible to repair deteriorated navigation lock walls in an operational lock with only minor impact on costs. For the generic 600-ft-long by 110-ft-wide lock, repair costs were estimated at $140/sq ft and would require 16 weeks for completion, assuming 5-day work weeks with 12-hr days. Although the concepts described were developed specifically for installation of stay-in-place forms in an operational navigation lock, they are potentially applicable to other concrete walls requiring repair under water. Potential applications include tailrace wingwalls, floodwalls, and stilling basin walls. (Lantz-PTT) JF - Available from the National Technical Information Service, Springfield VA. 22161.

AN - 36408011; 2194 AB - PURPOSE: Flood protection through renovation and construction of five miles of levees along the banks of the Raccoon River and Walnut and Jordan creeks near their confluence in Des Moines and West Des Moines, Polk County, Iowa is proposed. The recommended plan would involve raising an existing levee and constructing new levees along the north bank of the Raccoon River, with a tie-off along the north bank of Jordan Creek and along the west bank of Walnut Creek. Ponding areas to provide internal drainage and two borrow areas would be included in the proposed plan. This draft supplement to the final environmental impact statement of June 1977 is based on a general reevaluation of the project design undertaken in 1988. The reevaluation resulted in: (1) reaffirmation of the economic feasibility for flood control and recreation development along the Raccoon River and Walnut Creek; (2) modification of the flood control alignment to incorporate new floodplain delineation limits and developments completed since 1975; (3) implementation of policy changes regarding recommended levels of protection and project cost sharing; (4) renewal of statements of local sponsor support; and (5) provisions to avoid adverse environmental effects. As a result of the reevaluation, the level of protection afforded by the project design has been decreased from protection against the 200-year frequency flood to protection against the 100-year frequency event. Specifically, the project as currently proposed would consist of four miles of earthen levee, 900 feet of concrete floodwall, six mechanical closure structures, two sandbag closures, two pump stations, four ponding areas, three road ramps for access, three road ramps for maintenance, and two new access roads. Recreational facilities to be developed in association with the project would include 2.8 miles of bicycle paths, five bicycle ramps, two railroad crossings, two road crossings, one scenic overview, one parking lot, and one single-lane boat ramp to provide access to the Raccoon River. The estimated cost of the project is $17.7 million, with an annualized cost of $1.8 million. Flood control and recreational benefit-cost ratios are 1.8 and 1.3, respectively. POSITIVE IMPACTS: The levees would provide 100-year flood protection for approximately 900 acres within the cities of Des Moines and West Des Moines. The protected land areas include 904 residential, 227 commercial, and 11 public structures. Average annual flood control and recreational benefits would be worth $3.2 million and $1.4 million, respectively. NEGATIVE IMPACTS: A portion of the levee would be superimposed over Hoak Drive and would border an adjacent wooded area for approximately 1,500 feet between the roadway and Walnut Creek; disturbance to woody vegetation in this area would be likely. Approximately six acres in the vicinity of Denman Woods would be displaced. Ponding areas would be inundated during flood flows. Borrow areas would include agricultural land. One residence and two businesses would be displaced by the project.

AN - 36399131; 2197 AB - PURPOSE: Designation of an ocean dumping site for material dredged from the Barataria Bay Waterway (BBWW) in Jefferson Parish, Louisiana is proposed. The preferred site lies at the gulfward end of the BBWW and has been used for disposal of dredged material since 1960. It received interim designation as a disposal site by the Environmental Protection Agency in 1977. Approximately 500,000 cubic yards of dredged material are disposed in this site during each disposal operation, which generally occurs once every two to three years. Specific site coordinates are 29 degrees, 16 minutes, 10 seconds north latitude (N); 89 degrees, 56 minutes, 30 seconds west longitude (W); 29 degrees, 14 minutes, 19 seconds N; 89 degrees, 53 minutes, 16 seconds W; 29 degrees, 14 minutes N; 89 degrees, 53 minutes, 36 seconds W; 29 degrees, 16 minutes, 29 seconds N; 89 degrees, 55 minutes, 59 seconds W. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means for disposal of material dredged from the BBWW, ensuring the continued usefulness of the BBWW for navigational purposes. The BBWW would continue to serve the ports of Barataria and Lafitte and the Gulf Intracoastal Waterway. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, as well as localized burial of benthic organisms and temporary mounding of substrate.

Preparation date: March 28, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MIAMI HARBOR CHANNEL, FLORIDA: IMPROVEMENTS FOR NAVIGATION. AN - 36403042; 2191 AB - PURPOSE: Improvement of Miami Harbor in Biscayne Bay, Florida is proposed to provide increased depths in the existing federal and other locally created channels. Biscayne Bay is a shallow saltwater sound on the Atlantic coast near the southern end of the Florida peninsula. The immediate tributary area for Miami Harbor is Dade County, which depends on the port for some basic commodities. The recommended project would involve modification of the harbor to provide a channel 41 feet deep and 500 feet wide from the open ocean to the existing beach line. The channel would reduce to 39 feet deep and 400 feet wide at the beach line and remain at those dimensions to the Fisher Island turning basin. The project would also include deepening the South Lummus Island channel to 39 feet over a bottom width of 400 feet from the Fisher Island turning basin to the west end of the four container berths at Lummus Island; this channel would terminate at a turning basin centered around the existing Lummus Island turning basin. The turning basin would be dredged to a depth of 39 feet and would have a diameter of 1,600 feet. All dredged material would be dumped in the Miami Ocean Dredged Material Disposal Site, which is presently undergoing final designation for use by the Environmental Protection Agency. The first cost of the project is estimated at $34.39 million; increases in annual maintenance costs are estimated at $5,000. Annualized values of benefits and costs are estimated at $4.7 million and $3.6 million, respectively, and the benefit-cost ratio is estimated at 1.3. POSITIVE IMPACTS: Planned improvements would allow vessels to call at the harbor with increased draft and tonnage, resulting in transportation savings to shippers. NEGATIVE IMPACTS: Because most of the dredging would be done within the existing channel, where periodic disruptions from maintenance dredging and ship movements have not permitted the establishment of a diversified fauna, adverse environmental impacts would be restricted to seagrasses at the turning basin and impacts associated with blasting. The loss of marine seagrasses would be restricted to newly dredged areas of the Dodge/Lummus turning basin; the affected area would extend over 35 acres. Although seagrasses in the area are sometimes fed upon by manatees, it is unlikely that this endangered species would be seriously affected. Offshore disposal would result in cumulative impacts in the disposal area in that disposal would retard development of biota.

AN - 36390773; 2196 AB - PURPOSE: Implementation of flood control measures for the 418-square-mile Aloha-Rigolette drainage basin located on the left descending bank of the Red River in Louisiana is proposed. The flood control area lies in Grant and Rapides parishes. This draft supplement to the draft environmental impact statement of June 1985 provides a more detailed segregation and evaluation of the project drainage basin. Of the 22 initially considered plans, two were identified for final consideration. The tentatively selected plan would involve reconnecting Bayou Darrow to the Red River via floodgates and clearing and snagging 7.6 miles of Bayou Darrow. To offset the terrestrial habitat losses resulting from construction activities and flood control, the plan would include the purchase of 315 acres of agricultural lands; of those acres, approximately 20 would be converted to stream channel by reestablishing approximately 3.3 miles of relic stream channels. The remaining 295 acres would be reforested with woody plant species that provide valuable wildlife habitat. The loss of fishery habitat in Bayou Darrow would be offset by increasing the fishery resource of Iatt Lake. This latter goal would be accomplished by facilitating the drawdown of the lake to control its prevalent aquatic weed problem. Agricultural lands flooded by the drawdown would be those purchased and reforested to compensate for terrestrial losses. Seasonal flowage easements would be purchased on the 100 acres of woodlands flooded during the drawdown process. The flooding of this land would also partially compensate for the project-induced reduction of flooding during the overwintering waterfowl season. The annualized cost of the plan is estimated at $829,220, and the benefit-cost ratio is estimated at 1.25. POSITIVE IMPACTS: The project would reduce flooding in the agricultural area and create conditions favorable to intensified agricultural uses. The purchase of flowage easements would improve fishery resources. Annual benefits redounding from the plan would be valued at $1.0 million. NEGATIVE IMPACTS: Construction activities would alter 98 acres of open water habitat in Bayou Darrow and 302 acres of terrestrial riparian habitat along the bayou. In addition, 26 acres of bottomland hardwoods would be impacted due to floodgate construction and 18 acres of riparian habitat would be impacted due to the construction of two canal closures. The Bayou Darrow sport fishery would be reduced from 50 to 5 pounds per acre, and suitable overwintering waterfowl habitat would decline by 29,750 acre-days of flooding.

AN - 36390197; 2201 AB - PURPOSE: Designation of unconfined, open-water dredged material disposal sites within north and south Puget Sound waters of Washington State is proposed. Materials to be disposed at the site would consist of those dredged to improve and maintain navigation waterways of the Puget Sound. Over the period 1970-1985, an estimated 24.8 million cubic yards of sediments were removed from Puget Sound harbors and waterways by various dredgers. During the 1985-2000 Phase II operations considered here, 7.2 million cubic yards of bottom sediments could be dredged under the federal program; this compares with 7.9 million cubic yards removed between 1970 and 1985 under the auspices of the federal program. The Phase II management plan addresses the needs of unconfined, open-water disposal, including disposal site locations, dredged material evaluation procedures, disposal site management, disposal site environmental response monitoring, and dredged material data management. More extensive dredged material sampling and testing would be required than in the past, as well as improved disposal site management, including increased permit compliance inspections and environmental monitoring of site impacts. Five public multiuser unconfined open-water disposal sites would be identified as preferred. Preferred Phase II sites for nondispersive disposal have been identified in the south sound in the Nisqually reach between Anderson and Ketron islands and in the north sound in Bellingham Bay. Preferred dispersive sites have been identified in Rosario Strait, near Port Angeles, and near Port Townsend. POSITIVE IMPACTS: Dredging activities supported by the disposal sites would ensure the availability of Puget Sound waterways to the 34 port districts serving the region. Disposal of material dredged from some 50 miles of navigation channels, 50 miles of port terminal ship berths, and more than 200 small boat harbors would be allowed to continue. More dredged materials would likely be found acceptable for unconfined disposal than experienced under the interim open-water disposal regime. NEGATIVE IMPACTS: Overall dredged material disposal activities are expected to be more costly than in prior years. Use of disposal sites, particularly the nondispersive sites, would result in the smothering of benthos and alteration of bottom topography. Disposal activities would cause temporary, localized turbidity. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: March 17, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED RECONSTRUCTION OF M-59 FROM MOUND ROAD TO I-94, MACOMB COUNTY, MICHIGAN. AN - 36408361; 2171 AB - PURPOSE: Reconstruction of a 10.8-mile section of Michigan 59 (M-59), also known as Hall Road, in Macomb County, Michigan is proposed. The study corridor extends from Mound Road easterly to Interstate 94 (I-94). The project would involve construction of a depressed freeway from Mound Road to Utica Road and a boulevard from Utica Road to I-94; the project would lie along the existing M-59 alignment. More specifically, the facility would be a six-lane freeway from Mound Road to Utica Road, a seven-lane boulevard from the Clinton River to Van Dyke Road, an eight-lane boulevard from Van Dyke Road to Garfield Road, and a six-lane boulevard from Garfield Road to I-94. The boulevard sections would have median widths ranging from 26 to 124 feet. Mound Road would overpass M-59. An urban diamond interchange would provide access to M-59 from Mound Road. U-turn structures, both east and west of the interchange, would be provided. One-way service roads between Mound and Utica roads would be constructed; the service roads would be 24 feet wide with curb-and-gutter sections and an internal drainage system. Service drives would also be extended west of Mound Road for approximately 0.5 mile. At this point, a structure would be constructed over M-59 to route westbound traffic onto Doby Road. Doby Road would be a two-way facility from Ryan Road easterly to the bridge, where it would be converted to a one-way facility to Mound Road. A bridge at Merrill Street would be constructed to provide a more direct connection for north- and southbound commercial traffic to M-59. A three-lane bridge would be constructed north of the existing Clinton River Bridge to carry westbound traffic. An overpass would separate the boulevard from M-53. A new bridge would be constructed at the Middle Branch of the Clinton River to carry westbound traffic; the existing bridge would be widened. A partial cloverleaf interchange would be constructed at Rosso Highway and I-94. The estimated cost of the project is $81.1 million in 1988 dollars. POSITIVE IMPACTS: Reconstruction of this section of M-59 as a freeway would increase safety by relieving congestion and reducing traffic flow conflicts, accommodate both present and future traffic volumes, improve accessibility to properties adjacent to M-59 and beyond the immediate area, result in fuel conservation, improve profitability of businesses in the corridor, increase the value of taxable property, and complete a vital section of a regional transportation system. The project would be compatible with land uses in the downtown area of Utica. NEGATIVE IMPACTS: Rights-of-way requirements would displace 120 residential units, including 98 single-family units, 60 commercial establishments, and 3 farm units. Approximately 234 parcels would be directly affected. Acquisition of land and displacement of these structures would reduce the local tax base in the short term. Construction activities would result in the removal of some natural and ornamental vegetation in the rights-of-way, and expansion of the area under pavement would increase surface runoff of stormwater. In addition, the facility would modify 10 to 12 drainages and cross the Main, Middle, and North branches of the Clinton River, taking significant portions of the 100-year floodplain from these waterways. Encroachment on the floodplain could affect flooding characteristics in the Clinton River drainage basin, particularly within the watersheds of the North and Middle branches of the river. The freeway would traverse a nonattainment area for photochemical oxidants, and ambient noise levels would increase within the corridor.

AN - 36402377; 2174 AB - PURPOSE: Widening and realignment of the Coos Bay-Roseburg Highway (Highway 42) through the city of Coquille in Coos County, Oregon is proposed. The facility would feature four travel lanes, paved shoulders, and a paved median, with provisions for left-turn storage. Bicycle traffic would be accommodated on the shoulder, except in the downtown area, where bicycle lanes would be provided on both sides of the street. The design would include sidewalks and on-street parking along Main Street. The project would establish a new, shorter route, extending approximately 1.5 miles, across the Coquille River/Cunninghan Creek floodplain. Beginning at a point approximately 1,100 feet east of Cedar Point Road, the alignment would veer southeast to parallel the railroad tracks to a junction with Main Street at the north approach to the new Coquille River Bridge. From that point, the alignment would follow Main Street east to Adams Street and merge with the existing Coos Bay-Roseburg Highway. The highway would be built across portions of two log ponds and the Cunningham Creek/Coquille River floodplain on an earth and rock fill approximately 15 feet high and 1 mile long. An earth berm would be constructed to protect Sanford Heights from excessive noise. POSITIVE IMPACTS: Rerouting of the highway segment would reduce traffic congestion currently affecting the highway and improve traffic safety along the route. A more direct route would be provided through the downtown area to replace the narrow roadway, characterized by right-angle turns, that currently serves the corridor. NEGATIVE IMPACTS: Rights-of-way development would require displacement of eight businesses and two residences and placement of fill within 17 acres of floodplain and wetland areas characterized by weak underlying soils. The project would require 300,000 cubic yards of fill and 90,000 tons of rock and paving mix. Significant noise impacts would affect 36 receptors along the highway.

AN - 36408503; 2114 AB - PURPOSE: Implementation of a new master plan for the Mt. Hood Meadows Ski Area in Hood River County and the Mt. Hood National Forest, Oregon is proposed. Mt. Hood Ski Area lies on the southeast side of Mt. Hood and occupies 3,136 acres of scattered subalpine meadows, forested slopes, and above-timberline slopes. The site lies 70 miles east of Portland via U.S. 26. The area extends from elevation 4,000 feet at the east boundary near State Highway 35 to elevation 8,100 feet at the west boundary. The preferred alternative would provide for use of the ski area by 15,000 persons at one time. Facilities would include 13 lifts, five bases covering a total of 133.03 acres, 500 to 1,000 overnight units at each of one to three locations, a day lodge at Stringer Meadows, a restaurant, nordic center, handicapped skiers building, a picnic area and campground, and parking facilities for 6,752 vehicles. The permit for facility development and use would expand the Hood River Meadows permit area by 96 acres and extend 1,000 acres into the White River drainage. The total permit area would expand to 4,232 acres. Base facilities would include a 3.57-acre expansion of the Main Lodge Base, a 4.0-acre expansion at Hood River Meadows, a 64-acre Eastside Base, a 37-acre Westside Base, and a 5.6-acre Hotel Base. Overnight accommodations could include 500 units at the Westside Base, 500 units at the Hotel Base, and 1,000 units at the Eastside Base. Overnight accommodations would be built in phases, with a maximum of 250 units per phase. A summer use plan would be developed to ensure intensive management of all summer uses within designated areas to reduce and mitigate impacts. Summer uses would include hiking, horseback riding, tennis, swimming, and organized mountain biking. POSITIVE IMPACTS: Master plan implementation would prevent deterioration of the present quality of recreational opportunities due to overcrowding, provide high-quality downhill skiing and terrain balance for all levels of skiing proficiency, increase midweek and year-round use of the area in order to optimize operating economics, provide for sound land use and mountain resort design principles, maximize implementation of technological innovation, mitigate weekend traffic congestion problems on Highways 26 and 35, and maintain a reasonable and affordable recreational pricing structure for a broad base of the populace. NEGATIVE IMPACTS: Increased visitation would raise the risk of fire and traffic congestion. Alpine and critical soils would be particularly affected by construction activities. Summer use would result in soil compaction. Soil disturbances and increased impervious surface areas would increase runoff significantly in the long-term. Facility development would displace wetland and riparian habitat, degrade groundwater quality somewhat, and result in the permanent loss of vegetation and associated wildlife habitat. Some facilities would be visible from Gnarl Ridge and the Mt. Hood Wilderness, and these and other areas would be affected by increased visitation. Noise levels within the permit area would increase, and the commercial forest land base would decline. Other recreational activities would be displaced by alpine skiing. The demand for affordable employee housing and other human resources would rise in the area, while the availability of these resources is likely to decline.

AN - 36404046; 2139 AB - PURPOSE: Implementation of a flood control project for the Bassett Creek watershed in Hennepin County, Minnesota is proposed. The watershed lies west-southwest of the downtown section of Minneapolis in a highly disturbed and industrialized area. This draft supplement to the final environmental impact statement of July 1978 addresses changes in the design plan after it was determined that the proposed ponding (impoundment) area would have been located above a hazardous waste site, which required that the alignment of the flood control channel, as originally proposed, be changed. Like the original plan, the revised plan would involve structural and nonstructural measures. More specifically, the original plan would have involved the construction of a 1.5-mile underground conduit and deep tunnel, temporary storage areas, a permanent impoundment, channel modifications, embankments, floodwalls, culverts, and weirs. The ponding area at the mouth of the tunnel, proposed in the original plan, would not be constructed due to hazards from the contaminated waste site. Ponding during high runoff was intended to minimize the size and cost of tunnel construction. As a result, the newly revised plan would involve extending the creek channel enlargement for a distance of 1,500 feet upstream of the lower end in order to increase its capacity. In addition, 600 feet of new channel would be required to connect the creek to the new conduit. Although it was originally planned that the tunnel through glacial till be developed using a boring machine, economic analysis has demonstrated that the tunnel could be constructed more economically by surface excavation and placement of precast conduits. Floodplain evacuation, floodproofing, and continuation of floodplain regulation and flood insurance programs would constitute the nonstructural measures. POSITIVE IMPACTS: Flood protection provided to families and businesses would reduce economic losses, community disruption, and potential threats to public health and safety. Damages resulting from floods of less than a 100-year occurrence rate would be eliminated in portions of the watershed. Floodplain regulation would reduce future flood damages, and flood insurance would compensate owners for damages incurred from floods. NEGATIVE IMPACTS: Some trees would be removed to accommodate channel excavation. Approximately 152,000 cubic yards of excavated material would be placed in the Irving Avenue Dump Site, which is a hazardous waste facility. Channel excavation would expose currently stable creek banks to soil erosion and the creek to sedimentation by contaminated soils.

AN - 36407248; 2123 AB - PURPOSE: Reconstruction and realignment of 3.34 miles of Puerto Rico (PR) 26, known as the Baldorioty de Castro Freeway, in San Juan and Carolina, Puerto Rico are proposed. The project has been divided into two sections. The first section, extending from San Jorge to the San Jose Lagoon, would run along a viaduct structure, providing six travel lanes and frontage roads. The second section, extending from the San Jose Lagoon to the airport access road intersection, would provide a six-lane roadway on an embankment. Four construction alternatives are under consideration. Two of the alternatives would diverge from the existing alignment in front of the Llorens Torres Complex, close to the northwestern part of the lagoon. The other two alternatives would diverge from the existing alignment after traversing the Mundo Feliz Apartments. POSITIVE IMPACTS: The improved highway section would provide for expected average daily traffic volumes of 81,000 to 130,000 vehicles by the year 2010. The project would conform to the Land Use and Transportation Plan of San Juan Metropolitan Area and constitutes an integral part of the proposed transportation network. Improved travel times and safety would benefit both local and through travel highway users, and users would be provided with an improved view of the surroundings. NEGATIVE IMPACTS: Approximately 50 acres of mangroves would be converted to highway rights-of-way should an alternative involving divergence from the existing alignment in front of the Llorens Torres Complex be chosen. Area residents would be adversely affected due to the visual barrier created by the highway. A total of 12 structures would be displaced. Water quality within the San Jose Lagoon would be degraded temporarily under two of the alternatives. Increased traffic along the corridors would reduce air quality in the area. Projected noise levels would exceed federal standards in some areas; noise barriers would be ineffectual.

AN - 36398630; 2117 AB - PURPOSE: Upgrading to freeway standards of 6.3 miles of State Route (SR) 237 from Mathilda Avenue in Sunnyvale to Route 880 in the city of Milpitas, Santa Clara County, California is proposed. The existing highway between the Mathilda Avenue and Fair Oaks Avenue interchange consists of two lanes in each direction, separated by a landscaped median varying in width from 22 to 46 feet, with 8-foot outside shoulders. Moffett Park Drive on the north and Persian Drive on the south constitute the facility's frontage roads. The project would involve widening the roadway to eight lanes with auxiliary and high-occupancy-vehicle lanes, constructing three new interchanges at existing intersections, and reconstructing three interchanges and a railroad grade separation. The new cross-section would consist of an eight-lane facility with a 30-foot median. To accommodate the eight lane design, the project would involve realignment of the roadway north of the existing alignment, construction of two new through lanes in the eastbound direction and four lanes in the westbound direction, construction of noise walls along the south side of the alignment or along Persian Drive, construction of a median barrier, reconstruction of Moffett Park Drive, widening existing bridges over the Sunnyvale East Channel, and construction of 10-foot inside and outside shoulders. Interchanges providing access to and from Fair Oaks Avenue and the Lawrence Expressway would be reconstructed, and a new interchange would be constructed at the Great America Parkway. Grade separations would be provided at the railroad tracks and Lafayette Street. Signalized intersections would be provided at several locations. All bridges across Calabazas Creek, San Tomas Aquino Creek, and the Guadalupe River would be replaced. New interchange and roadway construction would be implemented near the points at which SR 237 crosses North First Street and Zanker Road, and the Coyote Creek bridges would be reconstructed. The estimated costs of rights-of-way acquisition, utility relocation, and construction are $81.7 million, $34.4 million, and $186.7 million, respectively. POSITIVE IMPACTS: The expanded facility would replace a facility that has been deemed inadequate to meet future demands. As a result, a major east-west thoroughfare between major north-south thoroughfares, such as SRs 101, 880, and 680, would be improved significantly. The socioeconomic status of lands served by the highway would improve significantly due to improved access and decreased travel times. NEGATIVE IMPACTS: Construction activities would result in the loss of agricultural land, displacement of residences and commercial establishments, loss of riparian land and other wetlands, loss of parkland, and relocation of utilities. The expanded capacity of SR 237 would induce socioeconomic growth, resulting in the further loss of nonurban land uses. Traffic patterns in the areas flanking the SR 237 corridor would change significantly. Approximately 3.8 acres of parkland would be displaced, and a frontage road providing access to a partly developed park would be removed.

AN - 36408669; 2138 AB - PURPOSE: Implementation of a plan to provide hurricane protection and beach erosion control for Topsail Island, North Carolina is proposed. Topsail Island is a barrier island located on the central North Carolina coast; it includes the communities of Topsail Beach, Surf City, and West Onslow Beach. The preferred plan would involve placement of a berm and dune extending along approximately three miles of the oceanfront at Topsail Beach, which is located at the southern end of the island near New Topsail Inlet. This portion of the island coast represents the only section of the 21.7-mile-long shoreline of the island where federal improvements would be justified. More specifically, the recommended plan would involve the development of an artificial sand dune constructed to an elevation of 13 feet above mean sea level (MSL), fronted by a storm berm constructed to an elevation of 9 feet above MSL. The berm and dune project would extend along a reach of 17,400 feet; this length would include 10,250 feet for the main fill and 7,150 feet for a transition at the northern end of the project. At the southern end of the fill, near New Topsail Inlet, a terminal groin would be constructed to control sediment losses from the fill. The terminal groin would involve construction of a horizontal section, at an elevation of 7 feet above MSL, extending from a landward anchorage point 260 feet seaward to approximately the intersection with the 7-foot-MSL contour of the beach fill. From this point, the groin would slope 1 vertical to 12 horizontal down to an elevation of MSL for a distance of 666 feet. The terminal groin would be constructed with prestressed concrete sheetpiles and scour protection would be provided by a rubble toe. The total length of the groin would be 1,010 feet. Approximately 3.2 million cubic yards of coarse to medium sand would be removed during initial dredging of Banks Channel, located behind the southern end of Topsail Island, and discharged along the ocean shoreline to Topsail Beach to construct the berm and dune. Maintenance or annual nourishment of the project would require 126,000 cubic yards of material. Renourishment of the project would occur at four-year intervals, requiring approximately 504,000 cubic yards of material per maintenance event. The pipeline route would be carefully selected to minimize impacts. The pipeline would be burlapped and welded with straps to provide maximum protection against leakage. In the event dune vegetation is lost, affected areas would be restored and replanted to reestablish preproject conditions. The estimated cost of the project is $12.5 million, and annualized costs are estimated at $1.6 million. The benefit-cost ratio is estimated at 1.4. POSITIVE IMPACTS: The principal project accomplishment would be the reduction of hurricane and storm damages to property and lands on the island. The project would also enhance the quality and quantity of the beach strand available for recreational uses. The possibility of an erosive breakthrough in the vicinity of the finger canals and long feeder channel north of the inlet could be avoided by nourishment of the unvegetated beach area and ocean shoreline. The value of average annual benefits would be $2.4 million. NEGATIVE IMPACTS: Topsail Island is known to be a nesting area for the threatened loggerhead sea turtle, which could be affected by project implementation and maintenance activities. Construction and maintenance activities would be timed, to the extent practicable, to avoid the turtle nesting season. The groin could cause some reshaping on the inlet side of the groin due to modifications in tidal currents and wave conditions.

AN - 36390486; 2137 AB - PURPOSE: Implementation of a flood control project to protect portions of the floodplain of the Ontonagon River within the corporate limits of the village of Ontonagon, Michigan is proposed. The village is located at the mouth of the Ontonagon River in north-central Ontonagon County. Major flooding occurred in the village of Ontonagon in 1912, 1922, 1942, and 1963 and, although an emergency levee was constructed by the local authorities after the 1963 flood, it provides only limited protection. Flooding results from high river discharges, heavy ice jams, and a combination of the two conditions. The selected flood control plan would involve upgrading and expanding the emergency earthen levee sections to provide the village with flood protection against the 500-year event. The completed levee system and its appurtenances would include 4,330 feet of upgraded or new clay fill levee, 950 feet of flashboard floodwall, 400 feet of concrete floodwall, interior drainage outlet structures, and a railroad closure structure. In addition, nonstructural flood damage reduction for five separate structures located on the west side of the river would be included in the project. The nonstructural measures would include floodproofing of a pumping station at a papermill, elevating damageable contents of the paper mill's storage building and lighthouse above the 500-year flood level, and construction of two separate levee sections to protect the paper mill and associated wastewater treatment facilities. The total project investment cost is estimated at $1.6 million, with an average annual cost of $153,000. The benefit-cost ratio is estimated at 2.3. POSITIVE IMPACTS: Flood protection would be provided for three sections within Ontonagon. Several long-term effects to the local fishery would result from levee construction, including reopening a slough to fish passage. Average annualized benefits would be valued at $345,630. NEGATIVE IMPACTS: Construction of the levees and appurtenant structures would permanently cover any vegetation existing in the path of the levee and the structures. In the southern reaches of the slough area, a small portion of wetlands would be affected by construction of outlet structures. Approximately .07 acre of palustrine wetland and adjacent forested shrub would be lost due to construction activities. Benthic organisms that have colonized shoreline areas where construction would occur would be smothered or removed. Some excavation work could affect cultural resource sites. Area aesthetics would be affected by increasing the height of the existing levee.

Preparation date: January 26, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CALVERT ROAD, U.S. ROUTE 1 TO MD ROUTE 201, PRINCE GEORGE'S COUNTY, MARYLAND. AN - 36404919; 2121 AB - PURPOSE: Replacement of the Calvert Road at-grade crossing of the Baltimore and Ohio (B&O) Railroad in Prince Georges County, Maryland is proposed. The Calvert Road study area is located in the northwestern portion of the county, northeast of Washington, D.C. It is bounded by MD Route 193 to the north, MD Route 201 to the east, MD Route 410 to the south, and U.S. Route 1 to the west. The project would provide a means of vehicular access between U.S. Route 1 and MD Route 201 and to the College Park Metro Station following the closing of the existing Calvert Road at-grade crossing of the B&O Railroad. The at-grade crossing must be closed due to the future placement of a Washington Metrorail track along this portion of the B&O railway; Metro's use of ""third rail'' electrification would prevent the possibility of an at-grade crossing. The existing average daily traffic at the crossing is 16,400 vehicles. The preferred alternative would involve construction of a four- to five-lane roadway on the south side of Paint Branch from the U.S. Route 1 /Campus Drive intersection to existing Calvert Road just west of the Northwest Branch of the Anacostia River, widening the existing Calvert Road from just west of the Northeast Branch to MD Route 201, and improvements to the MD Route 201/Calvert Road intersection. The existing Calvert Road crossing of the B&O Railroad would be closed. The estimated cost of the project is $24.1 million. POSITIVE IMPACTS: The new crossing would allow traffic to move efficiently through the study area at increased speeds, thereby reducing the amount of air pollutants per vehicle. The proposal would make the study area more attractive for economic development, thereby increasing employment opportunities and producing an increase in the tax base. NEGATIVE IMPACTS: Residential displacements could be required during implementation of the project. In addition, 14 to 16 commercial developments would result. Traffic noise impacts would affect residences between Rhode Island Avenue and the railway, where six residences would be within 200 feet of the road; noise impacts would be mitigated via provision of a berm and/or barrier. Approximately 1.2 acres of wetland would be lost, and sites listed on or eligible for the National Register of Historic Places would be impacted. Portions of the Anacostia River Park, Paint Branch Stream Valley Park, College Park Airport, and College Park City Park could or would be lost to rights-of-way development.

Preparation date: January 19, 1989 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COMMERCIAL DREDGING ACTIVITIES ON THE KANSAS RIVER, KANSAS. AN - 36398751; 2134 AB - PURPOSE: A Regulatory Plan for commercial sand and gravel dredging operations on the Kansas River in Kansas is proposed. The Kansas River is an alluvial stream that flows in an easterly direction for 170 miles across the state of Kansas between Junction City and the Kansas-Missouri state line. The Restricted Dredging alternative has been selected as the approach to be used in the Regulatory Plan. This alternative would restrict the level of allowable bed degradation; establish minimum allowable distances from structures, banklines, and similar features; and restrict the quantity of material to be extracted. Whether or not dredging would be allowed to continue along a certain reach of the Kansas River would be determined under this alternative, by the extent of degradation observed. Two feet have been established as the maximum acceptable level of bed degradation. The amount of degradation would, in turn, be measured by a monitoring program. The selected alternative would also retain and/or modify the existing minimum distance restrictions between dredges and the land and structures located in or adjacent to the river channel. New restrictions would also establish minimum distances between adjacent dredging operations. Since some aspects of this measure have been used successfully in the past to prevent and/or reduce degradation on a local basis, it would be retained for further analysis, recognizing that its effects would extend only to local situations. In addition, this alternative would limit the amount of material that could be removed from the Kansas River; the limit would apply to both individual dredgers and to specific reaches of the river. The production of the dredgers would be monitored. The exact relationship between the amount of material dredged and the amount of degradation that results is not known precisely. Results from a monitoring program would be needed to better define this relationship. This feature has been retained for further consideration because the quantity of sand and gravel extracted from the river is an important factor affecting the stability of the river channel. POSITIVE IMPACTS: Implementation of a restricted dredging plan would limit the environmental and economic impacts associated with commercial dredging on the river while avoiding extreme burdens on the overall dredging industry or its customers. Limiting the quantity of material allowed to be extracted would provide some control over the magnitude of localized impacts in the vicinity of a dredge and also overall impacts within a given reach of the river. Slight decreases in flood frequency in the De Soto area would result. Boating opportunities would increase somewhat in the De Soto area as well. Habitat for the blue sucker, a state-listed threatened species, would improve during the short-term. NEGATIVE IMPACTS: Some dredging operations would move upstream, while others could move to land mining or Missouri River dredging; the newly affected lands and waters could suffer from the effects of dredging. The costs of dredged materials would rise. River degradation in the Topeka area and along the lower river reaches would continue and worsen. Some structural damage would continue to result from dredging too close to the riverbanks. Groundwater resources would continue to be degraded somewhat in areas of river bed degradation. The quality of habitat along the extreme lower section of the river would decline somewhat, and habitat for the blue sucker would decline in the long-run. Requirements for new dredge support areas could expose unknown cultural resource sites. LEGAL MANDATES: River and Harbor Act of 1899 (33 U.S.C. 401 et seq.).

AN - 36407749; 2136 AB - PURPOSE: Designation of the Mississippi River Gulf Outlet (MRGO) Ocean Dredged Material Disposal Site, located off the Deltaic Plain of southeast Louisiana, is proposed. The MRGO has a shoaling rate of 0.15 foot per month. Approximately 3.0 million cubic yards of dredged material are removed from the MRGO and require disposal each year. The existing site, which has been used since 1958, lies at the gulfward end of the outlet. It received interim designation by the Environmental Protection Agency in 1977, and the preferred alternative recommends the MRGO as the permanent ocean material disposal site. Disposal operations would be regulated to prevent unacceptable environmental degradation outside site boundaries. POSITIVE IMPACTS: Final designation of the site would ensure an area for disposal of material dredged during maintenance of the MRGO, which is vital to the economy of the region. The MRGO is an important entrance to the Port of New Orleans, the largest port on the Gulf of Mexico. Access to the port would be assured for commercial barge traffic carrying shell and lumber; vessels involved in shrimp, crab, and menhaden fisheries; and support vessels for offshore oil and gas activities. NEGATIVE IMPACTS: Dumping of material at the proposed site would result in the temporary alteration of site topography via mounding, smothering of benthos at the site, and temporary disturbance of the water column due to turbidity and chemical releases, as well as in the reduction of dissolved oxygen levels. Habitat at the site could be altered. LEGAL MANDATES: Marine Protection, Research, and Sanctuaries Act of 1972 (16 U.S.C. 1431 et seq.).

The equipment evaluation included newly developed four- and six-wheeled low-ground-pressure vehicles. This equipment is typically used to tow a rotary ditching device to create surface trenches to enhance drainage and dewatering of confined dredged material disposal sites. Studies were conducted during the Dredged Material Research Program (DMRP) (1973-1977) to identify and evaluate various pieces of low-ground-pressure construction equipment for use in dredged material containment areas. Procedures were developed (by modification of the existing NATO Reference Mobility Model (NRMM) and subsequent Army Mobility Model (AMM)) to predict the performance of this equipment for conducting various work functions (Green 1977, Willoughby 1977, 1978). Since completion of the DMRP, new equipment which can be used to trench the surface of dredged material containment areas has become available. The newly developed low-ground-pressure equipment is being used or is being considered for use by several Corps of Engineer (CE) Districts to conduct trenching operations in confined dredged material disposal areas. A number of questions have been raised regarding performance of this equipment and comparison of its performance to other available equipment. These recent studies were conducted to evaluate the performance of this newly developed low-ground-pressure equipment on soft soils in dredged material containment areas.

Geochemically, contaminant releases are usually limited to nutrients, with negligible releases of toxic metals and hydrocarbons. Biochemical interactions are infrequent with no clear trends, and elevated uptake of toxic metals and hydrocarbons is usually negligible. Land-based disposal alternatives appear to offer limited protection in relation to human impact as compared to aquatic discharge and, moreover, are often excessively costly. Land-based alternatives often drastically change the geochemistry of the dredged material with a subsequent enhanced release potential of chemical constituents. Land sites are usually located in or near highly productive nearshore areas or adjacent to, or in contact with, groundwater aquifers. Even highly contaminated dredged material can be disposed of in open water if sufficient care is exercised to ensure that the material is isolated from the biotic zone of the marine system. This approach involves disposal site management using capping techniques or locating disposal in abiotic areas. Dredged material should be regarded as a highly manageable material for disposal in the marine environment. Regulatory modification measures should include: (I) ocean dumping criteria compatible and consistent with inland disposal regulations, (2) mandatory ocean dumping protocol revised to a tiered or sequential hazard assessment approach, (3) primary ocean site designation authority for dredged material delegated to the U.S. Army Corps of Engineers, and (4) clarification of monitoring requirements.

Geologic, hydrogeologic, and water quality investigations and monitoring have identified the lateral and vertical extent of the chloride intrusion in the complex multi-aquifer system. Federal and state laws and Department of the Army regulations required containment of the saline intrusion to prevent off-post environmental and water quality damage. Successful containment also provides the possibility of using the remaining 10 million cubic yard capacity of the site. A combination of standard slurry trench and deep-well dewatering systems was selected as the method for controlling the chloride movement in the multi-aquifer system. A three-well dewatering array in the Castle Hayne limestone aquifer and 9000 linear feet of bentonite slurry trench wall in the two upper sand aquifers was constructed during late 1986 and early 1987. Monitoring of wells around the site has begun to show positive results of containment in the form of decreasing chloride concentrations.

The points on the streams include outlets of subbasins of about 5 sq mi sewage treatment plant outlets, and U.S. Geological Survey gaging stations in the basin. 7-1/2 minute-series topographic maps were used as base maps to obtain the data recorded; the drainage area boundaries and stream channels were recorded using a geographic information system (GIS). Database functions and other capabilities of the GIS were used to aggregate the data, determine drainage area of the subbasins, and determine stream channel lengths, lake area, and storage area. The subbasins were delineated on the basis of topographic features and human activities recorded on topographic maps. Data from field inspection and recent drainage ditch maps were transferred to the topographic maps. Drainage basins do not have fixed boundaries. Human activities along basin divides and within the basin, such as the installation of storm sewers, the drainage of wetlands, and the diversion of streams may alter the stream's drainage area. Selected basin characteristics for each of the subbasins in the Redwood River basin include stream rank, indicating the drainage pattern of the stream. The first-ranked river is the Redwood River.

Sediment transported from the upper basin of the Rio Grande de Loiza is eventually deposited in the bottom of Lago Loiza, a water reservoir. Suspended sediment data were collected from 1983 to 1986 from a 208 sq mi area extending from the headwaters of Rio Grande de Loiza to the Lago Loiza. The drainage areas range from 0.82 sq mi to 89.8 sq mi. Results are based on three years of data from a network of five daily- record stations and five partial-record stations. A total of 2 ,114 sediment samples were collected and analyzed during the investigation. Instantaneous concentrations of suspended sediment varied from 0 to 56, 100 mg/L. Instantaneous suspended sediment loads ranged from 0 tons/day to 817,000 tons/day. A total of 152 suspended sediment samples were analyzed for particle size distribution. Suspended sediment in the streams is composed mostly of silt and clay. Sand content ranged from 6 to 80% during high flows.

However, more and more of the water professionals ' analytical work depends on people-oriented techniques either to relate their activities to outside interests or to build better internal team relationships. Frequently, the major problems that engineers and scientists face are not technical. They are problems of reaching agreement on facts, alternatives, or solutions. Public involvement and conflict management techniques are keys to servicing such needs. After briefly describing public involvement and conflict management techniques, seven observations on why incorporating social and environmental objectives into water resources planning and management require these process techniques are presented; public planning and conflict management help to define the relationship between environmental quality and other social values, clarify the relationships between social values and structures, help to deal constructively with competing values, and are keys to defining the main dimensions of social acceptability.

AN - 15592846; 2245618 AB - A programmatic Environmental Impact Statement (EIS) was prepared to assess the environmental impacts to the Upper Mississippi River System (UMRS) from the major rehabilitation effort. The majority of the rehabilitation work has consisted of repair and replacement items. However, certain measures were identified as having the potential to increase navigation traffic and possibly cause cumulative impacts to the UMRS. A traffic analysis was conducted to determine whether operation of the measures would be likely to increase commercial navigation on the UMRS. The traffic analysis concluded that during the navigation season a very small increase in system traffic may occur with the proposed measures in place. This small increase is within the normal variability of any navigation season and would not result in system wide (cumulative) impacts to the UMRS that are measurable over the existing condition.

AN - 15592461; 2245591 AB - The report presents the results of an investigation of the flooding problems along the Illinois and Michigan Canal within La Salle and Grundy Counties, Illinois. The canal is owned and managed by the Illinois Department of Conservation (IDOC). In a letter dated August 19, 1983, the IDOC requested that the Section 205 study authority be enacted to examine the flooding problem. An initial appraisal was completed in 1988 and a reconnaissance study was initiated in February 1988. The purpose of the reconnaissance study is to define the flooding problem, identify potential solutions, and determine whether there is a Federal interest in a flood damage reduction plan, based on a preliminary appraisal of costs, benefits, and environmental impacts. The reconnaissance study phase is also the appropriate time to assess the level of interest and support in the potential solution by non-Federal interests.

A 3.8 billion yd3 debris avalanche deposited in the river valley had been continually eroding since the eruption. The sediment retention structure (SRS) would collect the sediment but allow for the migration of salmon and steelhead to the Cowlitz and Columbia rivers. The structure included an embankment dam, spillway, outlet works and a fish migration facility comprising a fish barrier across the river, fish ladder, collection pool and lock. Structural design of the SRS is discussed including mudflow and earthquake analysis. Completion was scheduled for February 1990.

A map of the area showing sampling locations is included, and data on the chemical composition and physical characteristics of the sediments and the dissolved oxygen content of rivers flowing into the harbour are tabulated. There was a high degree of pollution of sediments in the inner channels and this, together with seasonal oxygen deficits, caused benthic organisms to react with episodes of tolerance and depletion.

The importance of these mechanisms in the transformation and biogeochemical cycling of iron is highlighted. In all cases, the chemistry of the surface co-ordination controlled the reactivity of the iron oxide and, hence, the rate and pathway of dissolution. Examples given for the reductive dissolution with ascorbate indicate that reductive dissolution with complex-forming reductants occurred according to an inner-sphere electron transfer. In light-induced reductive dissolution of iron(III)(hydr)oxides, as well as in thermal reductive dissolution, the inner-sphere surface co-ordination of the electron donor to the oxide surface was essential for efficient photochemical (or thermal) redox reaction.

N1 - Last updated - 2011-12-12 ER - TY - RPRT T1 - LUMMI BAY MARINA, WHATCOM COUNTY, WASHINGTON. AN - 36398147; 2096 AB - PURPOSE: Development of a small-boat marina on Lummi Bay in Whatcom County, Washington is proposed. Lummi Bay is located on the Lummi Indian Reservation in western Whatcom County and adjacent to the Strait of Georgia and regional fishing grounds. The proposed plan would include (1) the development of a moorage basin for 438 commercial fishing boats; (2) a federal navigation channel, 7,300 feet long by 100 feet wide by 12 feet deep at mean lower low water, with timberpile breakwater protection at the marina entrance and a turning basin and access channel; (3) disposal of 1.5 million cubic yards of material from dredging behind containment dikes to provide 65 acres of fill for development related to the marina and commercial fishing by the Lummi Tribe; (4) mitigation of environmental damages via reintroduction of 65 acres of poorly flushed shallow-water habitat to increased tidal action, eelgrass plantings, installation of peregrine falcon perch poles, and environmental monitoring; and (5) maintenance dredging, with disposal at an open water site. Maintenance dredging would occur after 2, 6, and 10 years and, thereafter, at 5-year intervals; maintenance dredging would result in the removal of 40,000 cubic yards of material. The cost of construction in October 1987 dollars is $6.3 million, including $2.5 million allocated by the Federal Government and $3.7 million provided by the Lummi Indian Tribe. POSITIVE IMPACTS: Marina facilities would help alleviate the shortage of commercial fishing boat wet moorages in the county, and provide additional moorages for Indian and other fishing interests. Provision of additional moorages would reduce congestion at existing facilities, which have been impacted by congestion-related safety hazards. The employment base of the area, which is characterized by a high level of unemployment, would be enlarged significantly. Deep water resulting from channel construction could increase crab habitat in Lummi Bay, and construction of a fish passage at the marina entrance would allow juvenile salmon passage and minimize exposure to predation in open water. NEGATIVE IMPACTS: Dredging and other construction activities would eliminate 8.8 acres of valuable eelgrass habitat. Filling within the sea pond for upland construction would permanently remove productive benthos and 65 acres of shallow water habitat. Physical alteration of the area would decrease the value of avian habitat, and introduction of marina-related contaminants into the bay could affect fish and avian populations. Dredging and disposal would damage benthic habitat. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.) and River and Harbor Act of 1960, as amended (P.L. 86-645).

Preparation date: December 30, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SOUTHWEST LOCKPORT BYPASS (FROM ROBINSON ROAD TO NY 31), NIAGARA COUNTY, NEW YORK: P.I.N. 5568.08.101. AN - 36389935; 2070 AB - PURPOSE: Construction of a new two-lane road and reconstruction of Robinson Road to provide a four-lane highway within the town of Lockport, Niagara County, New York is proposed. The two-lane road would begin at the intersection of West Avenue (State Route 31) and Upper Mountain Road (Route 93) and proceed for a distance of 2.5 miles south and southeast to the intersection of Robinson Road. The remainder of the project would involve the improvement of existing local roads to form at-grade intersections with the new roadway and the widening of Robinson Road from two lanes (24-foot pavement width) to four lanes (48-foot pavement width) from the terminus of the new roadway to the intersection of Robinson Road and Transit Road (Route 78), a distance of 0.8 mile. Intersection improvements, including signalization where required, and construction of new at-grade railroad crossings, are also part of this project. New intersections would be constructed at Routes 31/93 and at Robinson Road, and the Robinson Road/Transit Road intersection would be reconstructed. A new bridge would be constructed over the Barge Canal and two new at-grade railroad crossings would be provided. Relocated at-grade intersections would be provided at Ohio Street and Summit Street with its connection to State Street. The estimated cost of the project is $9.27 million. POSITIVE IMPACTS: The project is expected to reduce traffic volume and travel times along Transit Road between Robinson Road and Route 31. A modern two-lane highway would be provided that would divert a significant amount of truck traffic destined for the Southwest Lockport Industrial Area and through traffic with destinations north and west of the city from the congested shopping corridor along Transit Road and the central areas of the city north of Robinson Road. The project could aid in reducing the number of accident occurrences and congestion in these areas. Industrial, commercial, and residential development in the area would provide an increase in the local tax base. Project-induced development in the area could result in a long-term increase in employment, which would further strengthen the area's economic base. NEGATIVE IMPACTS: The project would involve the placement of highway fill within regulated wetlands, and mitigation measures for the disturbed wetlands would be required. Agricultural impacts include the acquisition of active farmland and prime and important soils and the division of active farmland, cutting off access to portions of fields. Increased development pressures as a result of the construction could increase the potential for induced development and may result in additional conversion of farmland. Temporary (construction) and long-term (traffic) increases in noise levels are an unavoidable impact. Twenty-one residences and one apartment complex could experience noise levels in excess of the federal noise abatement criteria.

Preparation date: December 22, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SPACE SHUTTLE ADVANCED SOLID ROCKET MOTOR PROGRAM, HANCOCK AND TISHOMINGO COUNTIES, MISSISSIPPI AND BREVARD COUNTY, FLORIDA. AN - 36397782; 2056 AB - PURPOSE: Design, development, testing, and evaluation of Advanced Solid Rocket Motors (ASRM) to replace the motors currently used to launch the Space Shuttle are proposed. The proposed action would include the design, construction, and operation of new government-owned, contractor-operated facilities for manufacturing and testing the ASRMs. In addition, the action would involve the development and implementation of a scheme for transporting propellant-filled rocket motor segments from the manufacturing facility to the test and launch sites and return of the used and/or refurbished segments to the manufacturing site. Sites under consideration for the new facilities would include the John C. Stennis Space Center, Hancock County, Mississippi; the Yellow Creek site in Tishomingo County, Mississippi, which is currently in the custody and control of the Tennessee Valley Authority (TVA); and the John F. Kennedy Space Center in Brevard County, Florida. TVA would transfer its site to the custody and control of the National Aeronautics and Space Administration (NASA) if the Yellow Creek site is chosen. All facilities would have to be located at the same site. Existing facilities that could provide support for the program would include the Michoud Assembly Facility in New Orleans Parish, Louisiana and Slidell Computer Center in St. Tammany Parish, Louisiana. NASA's preferred test location is the Yellow Creek site, and its preferred test location is the Stennis Space Center. The ASRM would be 150 inches in diameter. Each motor would be produced and shipped in segments, which would then be joined at the test or launch site. Final design would specify two to four segments per motor. Each ASRM would carry 1.2 million pounds of propellant, with each segment containing 300,000 to 600,000 pounds of propellant. The estimate of waste propellant resulting from normal operations of off-specification batches would equal approximately 1.0 million pounds per year. Waste propellant disposal would be disposed of via open burning, incineration, recycling, reuse, and/or treatment. The ASRM production rate would be up to 30 motors per year, with 28 to be used for launching the Space Shuttle (14 space flight sets of 2 motors each), and 2 available for static testing. During the latter part of the developmental period, the ASRM would be tested on a horizontal test stand an average of four times per year. Thereafter, it would be tested twice a year. POSITIVE IMPACTS: Development and use of the ASRMs would enhance shuttle system reliability, safety, and performance. Federal expenditures on the Space Shuttle would be reduced, and privatization of the program would be encouraged. Employment associated with the development and operation of ASRM facilities would provide a boost to local economies. Full-time employment for the routine production of ASRMs would be 1,500, with an additional 150 employees needed for testing and 200 for ancillary production facilities. NEGATIVE IMPACTS: Facilities and explosive safety zones would occupy 1,100 to 2,500 acres, depending on whether manufacturing and testing facilities are located at the same site. Depending on the site chosen, small amounts of wetlands could be filled and wildlife habitat displaced. Test firing the motors and disposing of waste propellant by burning would release pollutants into the ambient atmosphere; surface water, vegetation, and wildlife in the safety clear zone would be minimally affected by these localized air pollutants. Areas adjacent to the test sites would be exposed to high noise levels during test periods, which would occur two to four times per year. The Yellow Creek site contains 227 archaeological sites of some significance, a situation that has led to its nomination by the TVA as an historic district; development of the site would infringe on the normal uses of a site so designated. Site surveys of the John F. Kennedy Space Center have not yet been completed. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: December 16,1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED BOBBY JONES EXPRESSWAY EXTENSION, PROJECT F-117-1(11), RICHMOND COUNTY, GEORGIA AND AIKEN COUNTY, SOUTH CAROLINA. AN - 36398207; 2062 AB - PURPOSE: Extension of the Bobby Jones Expressway from Old Savannah Road in Augusta, Georgia to U.S. Route 1 in Aiken County, South Carolina is proposed. The four-lane, controlled-access facility would extend easterly from Old Savannah Road for a short distance to a point on the existing Bobby Jones Expressway located in the vicinity of New Savannah Road. Curving slightly north of the existing intersection with New Savannah Road, the alignment would then extend northeasterly on new location for an overall distance of 8.1 miles to its terminus on U.S. 1. Some modifications of the already completed expressway in the vicinity of New Savannah Road would be required. The alignment would include construction of a bridge structure over a partial cloverleaf interchange at New Savannah Road, a split-diamond interchange at Laney Walker Boulevard and San Bar Ferry Road, and a partial cloverleaf interchange at the project terminus on U.S. 1. Bridges with wildlife passage would be provided at Phinizy Ditch and Beaverdam Ditch within the Georgia section. The estimated costs of rights-of-way acquisition and construction for the Georgia portion of the project are $1.7 million and $46.6 million, respectively. The construction cost for the South Carolina portion of the project is estimated at $20.6 million; the cost of rights-of-way acquisition for the South Carolina portion of the project is unknown. POSITIVE IMPACTS: The proposed facility would provide a link from the central business district of Augusta to Interstate 20 (I-20) in South Carolina; I-20 provides a bypass of Augusta. Traffic accidents and congestion on local arterial streets would decline, and fuel efficiency and air quality within the central business district would improve. NEGATIVE IMPACTS: One partial commercial displacement would be required due to rights-of-way development. Construction activities would impact 12 archaeological sites, 5 of which would require mitigation measures. The project would displace significant amounts of wetlands and forest habitat.

AN - 36382385; 2058 AB - PURPOSE: Construction of a 4.4-mile-long bypass of the city of Cloverdale in northern Sonoma County, California is proposed. The project would involve construction of a four-lane freeway bypass of the developed portions of Cloverdale from a point 0.6 mile north of Hiatt Road to Preston Overhead. South of First Street/Crocker Road, the alignment would traverse nearly flat to gently rolling terrain on alluvial terraces. North of First Street, the alignment would pass through a low ridge and then back on to nearly flat alluvial terraces at the confluence of the Russian River with Oat Valley and Big Sulphur creeks. Interchanges would be provided at the projected termini and at a point approximately midway along the alignment at the extension of Cloverdale Boulevard. An undercrossing would be constructed at North First Street and a railroad underpass at Cloverdale Boulevard extension. The existing truck weighing station at the south end of the project would be relocated; this latter element of the plan would be cleared for implementation as a separate project when preliminary plans are drawn up. A Pacific Gas and Electric Company substation would also be relocated to a site adjacent to the Cloverdale Sewage treatment plant. Relocation of track owned and operated by the Northwestern Pacific Railroad would be required to prevent numerous crossings of the rail line by the bypass. In addition, the freeway would feature a frontage road along its east side between the south end of the alignment and North First Street/Crocker Road; the frontage road would provide local access to severed lands between the facility and the Russian River. The cost of construction is estimated at $33.0 million in 1986 dollars; this figure excludes rights-of-way costs and certain mitigation costs. The estimated rights-of-way costs for the acquisition of 35 acres and relocation of the substation amount to $2.2 million in 1986 dollars. POSITIVE IMPACTS: The freeway would provide a bypass for Route 101 which, within the project limits, constitutes one of the last highway segments through a city as large as Cloverdale that has not been improved to freeway or expressway standards. The freeway would relieve traffic congestion in the business district of Cloverdale. Local east-west circulation would be improved substantially, and community disruption caused by the passage of long-distance travelers through the local area would be eliminated. NEGATIVE IMPACTS: Rights-of-way development would displace approximately 200 acres, approximately 80 percent of which are now under state ownership, and would affect the Northwestern Pacific Railroad Depot, a property included on the National Register of Historic Places. Riparian and other wetland vegetation would be lost. Noise levels along portions of the freeway would increase.

Preparation date: December 13, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD CONTROL PLAN FOR THE MAIN STEM PASSAIC RIVER BASIN, NEW JERSEY AND NEW YORK. AN - 36403968; 2091 AB - PURPOSE: Implementation of a flood control plan for the Passaic River Basin in all or parts of Passaic, Bergen, Morris, Essex, Sussex, Hudson, Union, and Somerset counties in New Jersey and Rockland and Orange counties in New York is proposed. The recommended flood management plan for the basin, referred to as the Dual Inlet Tunnel Plan, is designed to protect against flooding, ranging from 100- to 500-year events intermittently, depending on locations. This plan would require a 13.5-mile-long, 39-foot-diameter tunnel between Wayne and Clifton, New Jersey and a 1.2-mile-long, 22-foot-diameter tunnel spur with an inlet at Two Bridges to convey floodwaters from an inlet just below the Passaic River-Pompton River confluence to an underground connection with the main diversion tunnel. Some 5.9 miles of channel modifications would be required to direct the flows into the inlet intake structures, and the diversion tunnels would be augmented by 23.7 miles of levees and 14.0 miles of floodwalls. The tunnels would be entirely underground, ranging from 125 to 450 feet under the surface. Structural flood control measures would be required to direct flood flows into the inlet. A major nonstructural component, preservation of 5,350 acres of natural storage, including 5,200 acres of wetlands, is also included. POSITIVE IMPACTS: All sites within the 100- to 500-year floodplains would be protected. Transportation delays as a result of flooding would be eliminated, property values would increase, and the habitat of endangered species would be protected. The shoreline would be cleaned, but access for recreation would be present only at selected points. Examination of the area might result in the possible discovery of new prehistoric sites. NEGATIVE IMPACTS: Two acres of riverine flats at the tunnel outfalls and a total of 10 acres of wetlands in the Little Falls area would be lost, with a total wetlands loss of 150 acres. Construction and maintenance would affect fisheries. Temporary increases of noise and traffic delays would also be experienced during construction.

AN - 36398349; 2098 AB - PURPOSE: Implementation of a plan to control the chronic seepage problem that threatens the safety of the Mill Creek Dam in Walla Walla County, Washington is proposed. This document supplements the final environmental impact statement of June 1975 on the operation and maintenance of the dam. The Mill Creek Project, which is located three miles east of Walla Walla on Mill Creek at Rooks Park, is an off-stream storage dam and reservoir with return channels to Mill and Russell creeks. The project was initially authorized to provide flood control protection for the city of Walla Walla. Since 1953, a lake has been maintained at the project site for recreational use. The diversion dam associated with the project is a concrete structure 23 feet high and 2,200 feet long. The storage dam is a cobble-covered silt structure 125 feet high and 3,200 feet long. The reservoir created by the dam is capable of storing a maximum of 8,300 acre-feet of water during a flood event. Previous attempts to control seepage from the dam have not been completely successful, and additional corrective measures are necessary to restore safe water storage capabilities. Under the preferred alternative, an impermeable high-density polyethylene membrane, 8 millimeters thick, would be placed along the lake bottom to an elevation of 1,215 feet above mean sea level (MSL); the liner would seal the lake bottom and prevent water from flowing into the dam conglomerate. Once the liner was in place and sealed, it would be covered with one foot of silt excavated from existing borrow areas. The silt would anchor the liner, protect it from animals and vandals, and provide substrate for aquatic organisms. The lake would then be filled, during the following spring, to an elevation of 1,214 feet above MSL. The liner would have a useful life of 50 years. The estimated cost of the project is $5.2 million. POSITIVE IMPACTS: The liner would make the reservoir safe, preventing possible dam breakages due to seepage erosion and would provide a larger, more naturally functioning lake system. Wetlands and littoral zone vegetation would be established, and lake water quality would be maintained under the liner alternative. Significantly less water would be required from Mill Creek to maintain the conservation pool, and the recreational opportunities associated with the lake system would be maintained. NEGATIVE IMPACTS: Installation of the liner would require drying the lake in the spring following the flood season, removing vegetation up to 1,217 feet above MSL, and recontouring the lake bottom. Approximately 25 acres of riparian habitat would be lost. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.) and Flood Control Act of 1938 (P.L. 75-761).

Preparation date: December 2, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - Water resources assessment of Guyana AN - 51803281; 2004-069306 AB - Guyana, meaning "land of many waters", is rich in hydrologic resources. Most of the population and economic base of the country is concentrated in the low-lying coastal plains, much of which is below sea level. This area, subject to inundation, is protected by a series of sea walls, which compose a coastal sea defense system. Since repairs and maintenance of the sea defenses are very expensive, the system is in a state of disrepair, and the coastal areas are sometimes "flooded" by the sea. Throughout the populated coastal plain and part of the interior highlands, there is a system of drainage and irrigation canals that feeds shallow reservoirs, known as "conservancies", that are designed to provide primarily irrigation water and secondarily other water needs. These drainage and irrigation systems, once adequate, have deteriorated because of lack of maintenance and can no longer sufficiently provide crop irrigation, much less other water needs. The lack of storage capacity has hindered agricultural production, which is one of the most important sectors of the economy. As a result of surface water supply shortages, ground water is being used to supplement the domestic water requirements. Ground water from the coastal aquifer system, which consists of three distinct aquifers, provides about 90 percent of the domestic water for the country. Presently these aquifers, particularly the "A Sand" aquifer which is the middle aquifer, provide ample water for the country's coastal population. However, from approximately 1913 to 1993, dewatering of the "A Sand" aquifer caused the head to fall almost 20 meters. Long-term studies on this aquifer system are needed to determine its capability to sustain increased withdrawals, as ground water will be more heavily relied upon to provide more of the water supply in the future. Hydrologic data are lacking throughout the country, particularly since the late 1960's when data collection decreased dramatically. Although no hydropower power exists, the water resources of the country offer significant potential, but development is prohibited by difficult access due to lack of roads. Wastewater treatment is minimal nationwide. As a result, surface water is laden with sewage, particularly in the heavily populated coastal areas.

AN - 36406515; 2051 AB - PURPOSE: Implementation of a plan for management of water levels in Reelfoot Lake, located in Obion and Lake counties, Tennessee and Fulton County, Kentucky, is proposed. The lake, Tennessee's only natural lake, was formed during the New Madrid earthquakes of 1811 and 1812 and lies three miles east of the Mississippi River within the Mississippi River Alluvial Plain. Approximately 29,506 acres in the vicinity of the lake are publicly owned. The environmental problems of Reelfoot Lake stem from sedimentaton and hypereutrophic conditions. Although various structural measures and soil conservation practices have been implemented in the lake's watershed, erosion and sediment deposition are still the major problems. The accumulation of undecomposed organic material and high nutrient inflow, combined with limited water level fluctuation, contribute to the hypereutrophic condition. The preferred alternative would involve an integrated water level management program that would combine dynamic water fluctuation and major drawdown components. The dynamic water fluctuation component would involve management of the surface elevation of Reelfoot Lake for a dynamic, natural fluctuation, depending on the natural moisture regime in particular years. Water levels would be managed for at least a two-foot seasonal fluctuation between elevations 284 feet above mean sea level (MSL) and 280 feet above MSL each year. The major drawdown alternative would involve periodically lowering lake levels by four feet with the present water control structure or up to eight feet with a new water control structure; the drawdown would occur every 5 to 10 years and would begin on June 1 and be completed by July 15 or, in the case of the new water structure, earlier than July 15. A minimum of 120 days would be permitted for drying and refilling; startup of this period would be between November 1 and November 15. Following the drawdown, the lake would gradually refill and be held at 283.2 feet above MSL until June 1 of the following year. POSITIVE IMPACTS: Water management under the preferred alternative would permit the widest range of options to enhance and preserve the major habitats at Reelfoot Lake. Sport fish populations would increase almost immediately, and lake longevity would be extended. Semiaquatic furbearers and game mammals would benefit from the greater variety of habitats created by water level fluctuations. Winter waterfowl and wood duck breeding habitat would increase and improve. Other bird use would be enhanced by fluctuations. Most listed threatened and endangered species would benefit. NEGATIVE IMPACTS: Extreme fluctuations during some years would result in fish kills and losses of furbearers, waterfowl, marsh birds, and wadding birds, but these effects would be short-term. Some potential would exist for outbreaks of botulism in waterfowl during the drawdown periods, and drawdowns would impact certain threatened and endangered species.

AN - 36398268; 2067 AB - PURPOSE: Reconstruction of U.S. Route 1 (Belair Road) from Silver Spring Road in Baltimore County to Maryland Route 152 in Harford County, Maryland is proposed. Two basic build alternatives, a six-lane cross-section and a four-lane cross-section, were considered before the six-lane alternative was determined to be preferable. The project would generally follow the existing horizontal alignment with widening on one or both sides, depending on physical constraints and environmental considerations. Where possible, consideration was given to modifying the rolling nature and steep grades on the existing alignment. A minimum of six through lanes would be provided throughout the project length. The typical cross-section would vary from segment to segment. Frequent median crossovers would be provided in urbanized areas. In less developed areas, the median crossovers would be restricted to major crossroads. Through park areas, a narrow New Jersey type concrete median would be used to minimize rights-of-way requirements. A number of options were studied for the Kingsville Community in an attempt to minimize community impacts and to avoid impacts to historic sites. Depending on the option chosen, estimated costs of the project range from $73 million to $79 million. POSITIVE IMPACTS: Project improvements would alleviate safety deficiencies and provide adequate capacity for vehicular traffic through the year 2015; a 100 percent increase in traffic volumes is expected over the next 20 years. Access to and from areas in the adjacent northeastern Baltimore area would be eased. Linkages to Kingsville, Fork, Benson, Fallston, Belair, Forest Hill, Hickory, and Churchville would be improved substantially. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 24 to 25 residential structures housing 44 to 45 families and 63 to 68 commercial structures containing 50 to 68 businesses. Approximately 5.9 acres of parkland, 17.3 acres of prime farmland, 1.5 to 1.6 acres of wetlands, and 1.5 acres of floodplain would be displaced. Traffic noise along the corridor would exceed federal standards at four to seven sites.

AN - 36390303; 2097 AB - PURPOSE: Modification or replacement of the existing holding and loading facilities for the downstream passage of juvenile fish at McNary Dam on the Columbia River near Umatilla, Oregon is proposed in a supplement to the final environmental impact statement of September 1976 on construction of the McNary Lock and Dam. The McNary site is located in Umatilla County at River Mile 292 on the Columbia River. The reservoir formed by the dam, known as Lake Wallula, extends 64 miles upstream of the dam. The new facility would consist of modification of the fish collection channel, replacement of the barge-loading facility, enlargement or replacement of the raceways for holding fish, construction of laboratory and office buildings, and installation of conveyance lines between the various components of the system. Four of the six plans under consideration would involve construction of completely new facilities for conveyance, handling, and laboratory work at one of three sites on the Oregon shore or one on the Washington shore. The other two plans would involve replacement of some of the existing fish collection and transport facilities, construction of additional holding raceways, and construction of a new loading facility. POSITIVE IMPACTS: Improvement of the fishery enhancement facilities would provide increased capacity and reduce mortality in the collection and bypass system. This would accommodate the increased numbers of migrating juvenile fish at McNary Dam that would otherwise exceed the capacity of the fishery enhancement facilities. Capacity requirements have increased from 4.0 million juvenile fish per year when the facility was first installed to 11.2 million fish in 1988 and are expected to increase by 20 million fish annually by 1995. NEGATIVE IMPACTS: Facilities could hamper barge-tow operations, and two plans would result in spillway spray affecting workers loading barges. Approximately one acre of wildlife habitat would be disturbed, and some excavation could be necessary. Minimal river disruption or displacement would result from dock construction or installation of a fish bypass pipe. Some shore area and, possibly, shore area and water restrictions could result.

AN - 36400814; 2072 AB - PURPOSE: Construction of a new north-south route in the West Memphis Area of Shelby County, Tennessee is proposed. The project would proceed from Split Oak Drive northward to Stage Road, a distance of approximately 10.0 miles. Sycamore Road would be extended by approximately 1.3 miles from Mullins Station Road to Kirby Parkway. The project would consist of improving some existing roads and some construction on new alignment to form a continuous route, to be designated as Kirby Parkway. The sections between Split Oak Drive and Stout Road and between Mullins Station Road and Reese Road would be widened. Construction on new alignment would be required between Stout Road and Messick Road, as well as between Humphreys Boulevard and Mullins Station Road, including the Sycamore View Road extension. One of the alternatives would require construction on new alignment at the north end of the project. While not proposed at this time, the section between Quail Hollow Road and Humphreys Boulevard would need to be widened to create the ultimate six-lane facility. The facility would provide three traffic lanes in each direction and either a continuous center lane or a raised median with turning lanes. The roadways would be flanked by curb-and-gutter sections and sidewalks. The design speed would be 50 miles per hour (mph) with a posted speed of 45 mph. Major structures would be constructed to carry the highway over the Wolf River, Interstate 40, Fletcher Creek, and Nonconnah Creek. Cost estimates of the project range from $39.8 million to $63.1 million, depending on the alternative alignment chosen. POSITIVE IMPACTS: Project implementation would improve local and regional accessibility and traffic service, improve route continuity, reduce traffic congestion on existing highways within the corridor, improve safety and operating conditions, and enhance future planned growth and development. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of up to 44 residences and 23 businesses and a reduction of wildlife habitat. A total of 95 to 145 acres of additional rights-of-way would be acquired and developed. Existence of the new highway would increase traffic volumes in some adjacent residential areas. The highway would traverse the Wolf River, Fletcher Creek, and Nonconnah Creek floodplains; however, none of the crossings would constitute a significant encroachment. Crossing of the Wolf River could result in the loss of wetland habitat. Whitten Park, hiking trails in the Shelby Forest Area, and the Shelby Farms Forest Natural Area could be impacted by rights-of-way development.

AN - 36397910; 2085 AB - PURPOSE: Implementation of an extensive flood control program, including channel work, dam construction and modification, land acquisition, and construction of recreational facilities, in Orange, Riverside, and San Bernardino counties, California is proposed. The recommended plan would consist of: construction of the Seven Oaks Dam in the upper Santa Ana Canyon to provide protection against the 350-year-frequency flood to the primary floodprone areas downstream of the dam; delineation of the 100-year floodway for the 35-mile reach between the Seven Oaks Dam and Prado Dam, with local authorities managing this area in accordance with guidelines established by the Federal Emergency Management Agency; modifications to the existing federal flood control levees at Mill Creek to restore their original level of protection; construction of a channel to contain the 100-year-frequency flood on the Oak Street Drain in the city of Corona; modification of the existing Prado Dam; channel improvements to provide 100-year-frequency protection along Santiago Creek in Orange County; construction of the Lower Santa Ana River Channel to provide 190-year-frequency protection; and enhancement of 84 acres of marshland at the mouth of the Santa Ana River to provide habitat for endangered species and restoration of 8 acres of marshland for additional habitat mitigation. A resource-use master plan, defining opportunities for recreational developments, has been prepared in lieu of specific recreation plans for Seven Oaks Dam and Prado Reservoir. Along the Lower Santa Ana River Channel, the recreation plan would provide for bicycle-hiking trails. On Santiago Creek, the recommended recreation plan would consist of a bicycle trail along the upper channel and around the perimeter of the gravel pits, in addition to a rest stop at the pits. The estimated cost of the project is $935 million, and the benefit-cost ratios for the Santiago Creek and Lower Santa Ana River portions of the project are 4.7 and 3.4, respectively. This final supplemental environmental impact statement addresses minor alternative measures under the project design, refines baseline studies and mitigation plans, reassesses mitigation for impacts due to construction of the Seven Oaks Dam, meets added study commitments made in prior environmental documents on the project, addresses the situation with three newly listed endangered species, and modifies or confirms previous environmental features relative to changes that have occurred in the existing and future environments. POSITIVE IMPACTS: Plan implementation would provide flood protection to urban areas in the three-county area, with emphasis on the heavily urbanized Lower Santa Ana River Basin in Orange County. Habitat for endangered species in the Santa Ana Wash and elsewhere would be protected. Other mitigation measures would protect or enhance 133 acres of vireo habitat, 1,100 acres within the Santa Ana Canyon, 84 acres of Santa Ana salt marsh, and 5 acres of pond. Up to 3.0 million cubic yards of beach sand for beach replenishment would be available due to project excavation. Numerous recreational opportunities would be created. NEGATIVE IMPACTS: Construction and expansion of the reservoirs would require relocation of homes and businesses and elimination of farmland. In addition, the project would result in significant losses of wetlands and other wildlife habitat and destruction of cultural resource sites; the historical integrity of the Southern California Edison hydroelectric system would be degraded .

The five projects would constitute a single carbon dioxide supply source (the Fontenelle Project) and carbon dioxide floods in four existing Wyoming oil fields. Once approved by the Federal Government, Amoco could decide to implement any combination of the five projects. The four fields that would be targeted for carbon dioxide flooding have been producing oil and gas for many years. To pursue carbon dioxide flooding in these fields, Amoco could be required to replace or upgrade the existing injection and production systems in the fields. The corrosive nature of carbon dioxide when mixed with water, combined with the higher operating pressures projected during the carbon dioxide floods, could make some of the waterflood equipment presently used in these fields inadequate. Precise plans and locations for wellfield-related activities are not available at this time. Therefore, specific impacts associated with individual wellfield-related activities are not analyzed on a case-by-case basis in this environmental impact statement. Potential worst-case impacts associated with development within each of the fields are summarized for each project. POSITIVE IMPACTS: The projects would represent Amoco's second step in an overall strategy to improve ultimate oil recovery from existing fields throughout Wyoming. Enhanced oil recovery in each of the fields would extend the economic limit of its productive life, increasing the ultimate oil recovery potential for the field. In addition to the economic benefits that would result from the production of oil, the projects would maintain local economies due to employment and other socioeconomic inputs. NEGATIVE IMPACTS: Project construction and operations could result in degradation of 50 acres of critical deer and antelope winter range, 59 acres of critical moose winter range, 60 acres of sage grouse breeding /nesting habitat, and seven acres of raptor nests and winter concentration areas. Some fugitive dust emissions would be expected in the area of construction and operations. Mineral and paleontological resources, visual qualities, recreation resources, and transportation services would be affected as well. Operation of sour gas wells and pipelines would result in some potential health hazards.

AN - 36397976; 2069 AB - PURPOSE: Improvement of Route 96 from Meadow Street in the city of Ithaca to Duboise Road in the town of Ithaca, Tompkins County, New York is proposed. The project would constitute localized improvement and would not be part of any long-range plan for Route 96 improvements. Three construction alternatives are under consideration. The project would consist of a one-way pair utilizing Meadow and Fulton streets within the city of Ithaca regardless of the alternative chosen. Alternative A would constitute a low-scale facility that would provide improvements only within the city. Route 96 traffic would be directed via an improved Buffalo Street, extending west from the intersection at Meadow Street, across the Old Cayuga Inlet and the Flood Control Channel, and connecting into Cliff Street (existing Route 96) at a point approximately 600 feet north of the existing Route 89 (Park Road) intersection with Cliff Street. A four-lane bridge would replace the existing crossing of the Old Cayuga Inlet, and a three-lane bridge would be built across the Flood Control Channel. Alternative B would consist of a two-lane facility with a truck climbing lane on new location. This alternative would resemble Alternative A except that Route 96 would be on new location from the Buffalo Street extension, across the Flood Control Channel in the city, to the vicinity of the Tompkins Community Hospital in the town of Ithaca. A new two-lane bridge would be constructed over new Route 96 near the south end of Cass Park to provide access to Cass Park from the West Hill area. Alternative C would be a four-lane divided facility on new location. The four-lane divided section would split into one-way directional pairs near the southern end of Cass Park. The new southbound Route 96 would connect into Buffalo Street and the new northbound Route 96 would connect into Meadow Street. Regardless of the alternative chosen, routes 96 and 89 would be separated from the "Octopus" intersection. The estimated costs of alternatives A, B, and C are $10.7 to $12.6 million, $27.9 million, and $39.8 to $40.4 million, respectively. The cost differential ranges for alternatives A and C are associated with alignment options. POSITIVE IMPACTS: Traffic congestion and dangerous movements at the intersection of routes 13A, 79, 89, and 96 (locally known as the "Octopus") would be eliminated. Travel time between the city and town would decline significantly. NEGATIVE IMPACTS: Rights-of-way requirements would result in up to 10 residential and 10 commercial displacements. Alternative B would result in displacement of the Paleontological Research Institution, and one structure eligible for inclusion on the National Register of Historic Places could be displaced. The project would require some relocation of the existing Cayuga Inlet Trail that runs along the west bank of the Flood Control Channel and displacement of some land at Cass Park. The project would encroach visually on Cass Park and the island area. The property tax base would be reduced slightly. Two to six sites would be impacted by traffic noise once the roadway facility was in operation; one site would be affected by noise levels in excess of federal standards.

AN - 36390076; 2088 AB - PURPOSE: Expansion of the capacity of the Gulfport Harbor deep draft navigation project in Harrison County, Mississippi is proposed. This environmental impact statement (EIS) constitutes a revision of the draft EIS of June 1976 and subsequent revisions. The preferred plan under the revised draft EIS involves widening and deepening the existing Gulfport Harbor navigation channel from its current 30- by 220-foot dimensions in the turning basin, anchorage area, and Mississippi Sound and 32- by 300-foot dimensions in the Gulf of Mexico up to the authorized dimensions of 36 feet deep by 300 feet wide and 30 feet deep by 400 feet wide, respectively. More specifically, the project would involve: deepening the entrance and southern portion of the anchorage basin to 36 feet; deepening the northern portion of the anchorage basin to 32 feet; deepening the Mississippi Sound channel to 36 feet; deepening the Ship Island Pass and Gulf channels to 38 feet; realigning the channel across the bar in Ship Island Pass approximately 1,500 feet to the west; and providing bend widening at various stations. Five alignments for the channel segment through Ship Island are under consideration. In addition, the expansion of existing port facilities through fill of 29 acres of shallow bottoms adjacent to the western side of the port would be considered. The expansion project would be accomplished by the Port of Gulfport and is currently under review through the Corps of Engineers regulatory program (Department of the Army Permit Application Number 88-00954-L). Material from initial and maintenance dredging would be disposed of in the designated ocean dredged material disposal areas on either side of the Gulfport Channel south of Ship Island pass. Mitigation for filling 29 acres of shallow bottoms would be accomplished by the Port of Gulfport under the auspices of the Corps regulatory program. The estimated cost of the project is $12.1 million, with additional annual operations and maintenance costs amounting to $607,840. POSITIVE IMPACTS: Increased capacity at Gulfport Harbor would decrease waterborne transportation costs and increase commerce in Harrison County, which is heavily dependent on the economic benefits offered by the harbor. Safety within the harbor would also be enhanced due to wider waterway turning capacity. NEGATIVE IMPACTS: Dredging and disposal of dredged material would result in temporary localized turbidity and alteration of bottom topography at the disposal site.

Corps projects are operated in a wide range of physica environments with numerous operational constraints. The Corps' Hydrologic Engineering Center (HEC) has developed a generalized simulation model capable of analyzing complex river-reservoir systems. The development of the model "HEC-5, Simulation of Flood Control and Conservation Systems" (Eichert, 1974,1975) has been paced by the changing mission of the Corps as well as the evolution of computer system. HEC-5 development and management, including code development, testing, documentation, training and field application experience, will be discussed. JF - Technical Papers.

When water is released to the downstream environment, reaeration occurs. Eventually, the water quality recovers to a more natural stream condition. The recovery distance, which depends on physical and biogeochemical factors, is often on the order of miles. To address this need, a study was conducted on poor water quality associated with deep, anoxic releases at four sites: (1) the tailwater of Lake Greeson, Little Missouri River, Arkansas; (2) tailwater of Nimrod Reservoir (Fourche La Fave River, Arkansas; (3) tailwater of Rough River Reservoir, Kentucky; and (4) Buford Dam tailwater on the Chattahoochee River, Georgia. The objectives were: to develop an improved understanding of chemical transformation in tailwaters; to provide guidance on sampling and analysis of tailwater quality; and to develop an easy-to-use PC model to predict impacts of reservoir releases on tailwater quality. Preliminary results are reported for the Greeson tailwater study only. The major process affecting DO concentrations was stream reaeration. Flow rate was shown to affect oxidation rates (e.g. for iron and manganese) so that a generalized formulation for reduced iron and manganese oxidation kinetics may need to account for the local temperature, DO concentration, pH, possible a flow-related variable, and the type of substrate in the stream. Results from the remaining field studies will be used to improve the kinetic formulations of the model.(Lantz-PTT) JF - Army Corps of Engineers Waterways Experiment Station, Vicksburg, MS.

AN - 36403607; 2033 AB - PURPOSE: The construction and operation by U.S. Borax and Chemical Corporation of a nominal 80,000 ton-per-day (tpd) molybdenum mine and processing facility at the Quartz Hill site, 45 miles east of Ketchikan, Alaska, in the Misty Fiord National Monument of the Tongass National Forest, is proposed. The Tongass National Forest is the last substantially intact temperate rainforest on Earth. This EIS addresses the impacts of the construction, operation, and post-mining abandonment of a mine, mill, and associated facilities at the Quartz Hill site. Significant issues include the effects of project water supply on area watercourses, the effects of tailings disposal, fisheries habitat protection, worker housing and possible impacts to Ketchikan, water quality protection, the effects of project activities on wildlife and habitats, and the protection of adjacent wilderness area values. The mine development project would consist of an open-pit mine, waste rock disposal areas, ore crushing and transport, a concentrator, tailings transport and disposal, employee housing, and support facilities such as roads, water supply, wastewater treatment, and power supply. The proposed action would include a mill at Tunnel Creek, marine tailings disposal in Wilson Arm, and workers living at single status housing at the project site and commuting during days off to Ketchikan. The Forest Service's (FS's) preferred alternative for mine development would locate the ore processing facilities in Tunnel Creek valley, generate electric power for the mine on-site, disallow creation of a townsite, access the mine along the route of the existing bulk sample access road, and obtain processing water from an impoundment on Tunnel Creek. When the mine production is increased from the initial 40,000 tpd capacity to 80,000 tpd, the water supply could be supplemented from a location near the mouth of the Blossom River. If necessary, a weir could be built to prevent saltwater intrusion into this supply. Anadromous fish passage would be assured in the design of this structure. Water withdrawals from the Blossom River would be managed so that an instream flow would be maintained sufficient for present and continued productivity of fish habitat. The FS's preferred alternative for tailings disposal would be marine disposal in the Wilson Arm. The Environmental Protection Agency (EPA) concurs with the FS preferred alternative with one exception. The EPA has concluded that the middle basin of Boca de Quadra is the environmentally preferred location for mill tailings disposal. POSITIVE IMPACTS: The Quartz Hill project would employ approximately 1,800 persons at the peak construction level and approximately 2,000 persons during project operations. The economies of the Ketchikan Gateway Borough and the region would receive significant benefits. NEGATIVE IMPACTS: Dust emissions from the mine and sulfur dioxide emissions from a power plant could exceed state air quality standards. The hydrologic regime of virtually all of White Creek, and substantial portions of Hill and Beaver creeks, would be essentially eliminated by development of the waste rock dumps and the open-pit mine. Water quality would be adversely affected by increased sediment loads, particularly during construction. Blasting noises in the wilderness area of Misty Fiords National Monument could disturb mountain goat populations. Avalanche danger in the project area would be high. Adverse impacts on freshwater fisheries would be relatively minor. Marine tailings disposal could adversely affect herring. Vegetation would be cleared from approximately 2,900 acres for project construction. Construction of the proposed wharf would eliminate one bald eagle nest. Some public services and facilities would be overloaded. Visual changes would result from the introduction of an industrial facility into a natural area.

AN - 36397876; 2082 AB - PURPOSE: Implementation of a flood control plan for the Dry Creek basin, located in Placer, Sacramento, and Sutter counties, California, is proposed. The 143-square-mile basin lies in the vicinity of the city of Roseville and the commmunity of Rio Linda in the southeast portion of the Sacramento Valley. Dry Creek extends 15 miles from its headwaters in the foothills of the Sierra Nevada near Newcastle into the Sacramento Valley to its discharge point at the Natomas East Main Drainage Canal. The study area includes Dry, Cirby, and Linda creeks in Placer County near Roseville. The flood control plan would include approximately 24,900 feet of channel improvements on Dry, Cirby, and Linda creeks, acquisition of some adjacent lands that are necessary to convey the design flow, and replacement of two roadway bridges and two pedestrian bridges. The plan would also provide additional recreational opportunities in the area, including a 19,000-foot-long multipurpose trail along Cirby and Linda creeks. A one-sided channel design would be used to reduce impacts to environmental resources in the area. In addition, a low-flow channel and riparian plantings on 61 acres of public land would be included as habitat mitigation measures. An additional 10 acres of mitigation land would be located out of the project area on the east bank of Dry Creek. The estimated first cost of the plan is $6.9 million, and annual costs are estimated at $659,000. The benefit-cost ratio is estimated at 1.2. POSITIVE IMPACTS: Plan implementation would substantially decrease flood damages in the study area. Flood damage for all floods up to and including the 25-year-frequency flood event would be eliminated, and damage from greater floods would be substantially reduced. Flood damages from the 100-year flood would decline by 90 percent. Areas adjacent to Dry Creek from the Southern Pacific Railroad crossing to Darling Way Bridge, Cirby Creek from Dry Creek to the confluence with Linda Creek, and Linda Creek to Old Auburn Road would benefit from flood control measures. Average annual benefits resulting from the plan include $606,000 in reduced flood damages, $50,000 in reduced local operation and maintenance costs, $47,000 in early bridge replacement savings, $16,000 in reduced flood insurance operating costs, and $87,000 in recreational benefits. NEGATIVE IMPACTS: Construction activities would temporarily impact 17.5 acres of stream channel and aquatic habitat, and plan implementation would result in the loss of 27.2 acres of high-quality riparian vegetation.

Preparation date: October 27, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOWER GRANITE PROJECT, SNAKE RIVER, ASOTIN, GARFIELD, AND WHITMA COUNTIES, WASHINGTON AND NEZ PERCE COUNTY, IDAHO (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1975 ON INTERIM NAVIGATION AND FLOOD PROTECTION DREDGING). AN - 36402264; 2095 AB - PURPOSE: Implementation of a navigation and flood control project is proposed in the confluence area of the Snake and Clearwater rivers of Nez Perce County, Idaho and Asotin, Garfield, and Whitman counties, Washington. Accumulation of sediment in the confluence area has been occurring as a result of the completion of Lower Granite Dam in 1975. Sedimentation reduces the level of flood protection provided to the city of Lewiston, Idaho and represents a potential threat to life and property. Sediment deposition also reduces water depths for navigation to the Ports of Whitman, Clarkston, and Lewiston. This statement, which supplements the final environmental impact statement (FEIS) of July 1975 on the dam project, evaluates an interim action to satisfy navigation and flood protection requirements within the Lower Granite Reservoir until a long-term solution can be selected and implemented. The supplement also discusses an in-water disposal test with monitoring in an adaptive process to obtain information in support of the evaluation of long-term in-water disposal. The project would involve annual dredging operations, commencing not earlier than December 15 and continuing until achievement of the sediment removal objective or March 31, whichever occurred sooner. Dredging would occur primarily in the Snake River at or near the confluence of the Clearwater River downstream of the Port of Whitman. Navigation dredging within the Clearwater River arm could include the access channel, berthing area, and turning basin for the Port of Lewiston. Approximately 400,000 cubic yards of sediment would be removed every three years to maintain navigation. Snake River flood protection dredging would require the removal of at least 800,000 cubic yards of material and as much as 1.2 million cubic yards of sediment annually from selected river reaches. In-water disposal would occur in mid-depth (20 to 60 feet deep) and deep water (deeper than 60 feet) sites below Snake River Mile 120. An integral part of this proposal would be a test of in-water disposal of dredged material to determine the effects of such disposal on the aquatic habitat and fishery resources in the reservoir. The upland disposal option would involve disposal in containment ponds presently on the Wilma Habitat Management Unit. This site would be capable of containing one upland disposal episode; additional upland sites would have to be located if more than one upland disposal episode occurred during the interim project. POSITIVE IMPACTS: Dredging would provide flood protection for the levee system associated with the reservoir and would clear navigation channels within the area. The in-water disposal monitoring program would assure that environmental damage due to disposal of dredged material would be minimized. NEGATIVE IMPACTS: Several physical-chemical effects related to dredging and disposal would occur in the rivers. Dredging and disposal operations would elevate turbidity and levels of suspended solids in the rivers. Contaminants would be released from sediment. Dissolved oxygen and temperature changes due to dredging and disposal would be slight. Benthic organisms would be destroyed. Use of the Wilma disposal site would destroy wildlife habitat and displace wildlife to habitat outside the affected area. A potential for conflict with a local sport fishery would exist at the mouth of the Clearwater River and in the reservoir near the in-water disposal activity.

AN - 36382146; 1997 AB - PURPOSE: Development of a 70,000-seat capacity football stadium, parking, and associated facilities in Los Angeles County, California is proposed by the Los Angeles Raiders and the city of Irwindale, California. The facilities would be maintained by the Raiders in Irwindale. This action is related to actions proposed by the Corps of Engineers and Irwindale. Administrative action is required that would change existing federal land uses from recreation, wildlife management, and natural uses to general patron parking and recreation of a different nature. Approval of the project would result in implementation of one of three options, including: (1) amendment of the existing Santa Fe Dam Master Plan and allowance of the Los Angeles County Department of Parks and Recreation to sublet lands to the city of Irwindale; (2) modification of the existing master lease agreement and direct leasing of lands to the city of Irwindale; or (3) declaration of the land as excess property via a special congressional authorization and selling the land at fair market value. The project would also require an amendment of the city of Irwindale General Plan and approval of the development of the stadium site and ancillary facilities, including proposed employee parking and a practice field/hall of fame complex that would be under the sole jurisdiction of the city. The stadium would be developed in an inactive sand and gravel quarry adjacent to the San Gabriel River. The facility would include a full range of amenities such as luxury boxes, club seating, and a stadium club, as well as nearby full capacity parking. POSITIVE IMPACTS: The new facility would replace a 65-year-old stadium near downtown Los Angeles designed for use as a track-and-field arena. The existing facility has a seating capacity of 92,500, which far exceeds the desirable level of seating for National Football League teams. This excessive seating capacity makes it difficult to sell out the stadium and deprives the Raiders of additional revenue associated with local televising of home games. The location of the proposed stadium would also be more amenable to its uses. NEGATIVE IMPACTS: Parking facilities would displace up to 178 acres currently used for open space, public recreation, preservation of natural lands, and wildlife management. The stadium would lie in a seismically active area. Construction and operation of the site would generate a significant amount of vehicular traffic. There would be a potential for significant flooding of the site during heavy rains. Dust from transfer and haulage of fill material for the stadium could cause health problems, particularly for the immunosuppressed population of the City of Hope Hospital. Fog and air quality could result in glaring conditions along the adjacent freeway due to stadium lighting, and parking area lighting could affect local residences. Alluvial scrub habitat would be displaced by parking lots.

AN - 36397827; 2007 AB - PURPOSE: Implementation of a major rehabilitation of Upper Mississippi River System (UMRS) Locks and Dams 2 to 22 between La Grange to Lockport is proposed. Waterways to be affected would include the Mississippi River and the Illinois Waterway. Sections of the affected waterways pass through Minnesota, Iowa, Illinois, and Wisconsin. The majority of the rehabilitation work would consist of repair and replacement efforts; however, certain measures would have the potential to cause cumulative impacts to the UMRS. These latter measures would include actions involving the following: (1) a submersible trainer gate at the Peoria and LaGrange locks and dams of the Illinois Waterway; (2) a guard wall at Lock and Dam 22 at Saverton, Missouri; (3) a vertical lift gate at Lock and Dam 20, Canton, Missouri; (4) high-volume bubbler systems at locks and dams 2 through 22 on the Mississippi River; (5) modification of the chamber outlet structure at Lock and Dam 15 at Rock Island, Illinois; and (6) extension of the upper guide walls at locks and dams 12 through 22 and of lower guide walls at locks and dams 21 and 22 on the Mississippi River. A traffic analysis was conducted to ascertain whether operation of the system following the proposed measures would be likely to increase commercial navigation and, hence, lead to systemwide impacts on the UMRS. The analysis concluded that, during the navigation season and by the year 2040, a 1.3 percent increase in system traffic, amounting to 2.1 million tons, would occur as a result of the proposed measures. This traffic increase would represent an average increase of approximately one tow per week on the Illinois Waterway and approximately two tows per week on the Mississippi River. POSITIVE IMPACTS: The coordinated development and enhancement of the UMRS would be ensured, while the associated ecosystem would be protected from significant damage. Regional economies would continue to receive support from commerce generated by inexpensive water transport of raw materials and goods. Bubbler systems would improve end-season navigation by expediting the withdrawal of tows from the UMRS. NEGATIVE IMPACTS: Although projected traffic increases would be minor, concern has been expressed that increases could be concentrated at the end of the navigation season due to the installation of high-volume bubbler systems that prevent the formation of ice. The traffic analysis identified the potential for an additional 10 to 20 lockages at the end of the navigation season due to the bubbler systems. End-season traffic would be highly variable and unpredictable. It appears, however, that end-season tows would be downbound, resulting from a desire to avoid ice entrapment. For this and other reasons, it does not appear that the bubbler systems would significantly affect traffic volumes. Incidental takes of an endangered mussel species could be increased by operation of the improved system.

The locks are located at the outlet to Lake Washington within the city of Seattle principally to pass commercial and recreational vessels between the lake and Puget Sound. Water to operate the locks is provided through local runoff and limited storage in Lake Washington. These sources of supply are subject to considerable stress from M&I users, urbanization, and diverse hydrometeorologic factors. Competition for the available water resource has become increasingly acute between USACE and city of Seattle which obtains nearly 70 percent of its M&I supply from the Cedar River, the main tributary to Lake Washington. Therefore, it is considered important that use of a continuous daily runoff model be investigated for forecasting the runoff available from sources other than the Cedar River to operate the locks and evaluate water conservation measures during low flow periods. To accomplish this task North Pacific Division's "Streamflow Synthesis and Reservoir Regulation Model - Version 8" (SSARR8) was selected to ensure that a large number of variables could be analyzed independently. Results of the calibration work would determine the value of such a model for reconstituting and forecasting daily streamflows and lake elevations, particularly during low flow sequences.

These changes have caused an upward trend in the magnitude of annual peak discharges at the Robinson's Branch gage, located about 1.2 miles upstream from the mouth. This upward trend required that an adjustment for historic urbanization be made to the sample of peak discharges, before a peak discharge vs. frequency relation could be determined by accepted statistical procedures.

Also, we wanted a model which would reflect the effects of any proposed flood control structures, such as dry bed reservoirs in any combination. Some of the key issues regarding the calibration of this model was the time of travel though the watershed, what type of unit hydrograph parameters to use, the time duration of the computation interval, and how good were the computed 1-through 500-year peak discharges under 1979 land uses. Results of the calibration and application of this model yielded very reasonable results when compared to observed and regional flow data. The effects of dry bed reservoirs in any combinations yielded reasonable answers.

The downstream third of the watershed is almost totally developed. It is estimated that by the year 2020 the entire watershed will be fully urbanized. Land use planning and flood control planning for this watershed have been given a high priority since the mid 1960s. Floodplain regulation mapping and land use development regulations have been in effect since the early 1970s.

This model was required to simulate the impacts of projected urbanization on the basin and to design and evaluate flood control alternatives which combined off-channel detention storage and channel improvements. The model was verified by reproducing available historical flood information. Peak discharge-frequency relationships were developed using TP-40 precipitation estimates and compared with U.S.G.S. regional regression methods. The design of the detention site components (storage requirements, control structures and weir configurations) was optimized using an in-house routing program specifically developed for this project. The resulting detention designs were incorporated in the HEC-1 model utilizing the diversion data option. The recommended plan is currently under construction and represents one of the first local cost-sharing agreements developed and signed under the criteria outlined in PL 99-662.

Lying 1000 miles southeast of Miami, Florida at 18 degrees north latitude, the main island is about 96 miles long east to west and 35 miles north to south with interior elevations reaching 4,400 feet above sea level. Puerto Rico offers a full range of challenges to the Hydraulic Engineer. Mountain watersheds with steep slopes, super-critical flow regimes and relatively high annual rainfall rates that flow into flat (usually two-dimensional) coastal floodplains with low annual rainfall rates and tidal outlets. Some of the topics we will discuss will be topography, areal rainfall distribution, temporal rainfall distribution, times of concentration, model selection and, as the title suggests, "calibration" with or without historical data. The thought processes of the Hydraulic Engineer, in a natural order of progression, will be followed.

As shown in Figure 1, the City of Roanoke is part of a larger metropolitan region known as the Roanoke Valley which also includes the City of Salem, the Town of Vinton and surrounding Roanoke County. The area is a thriving, progressive industrial and commercial area which is served by an excellent transportation system including major railroad lines and interstate highways. This valley area is surrounded by the Appalachian Mountains on the north and west and the Blue Ridge Mountains on the south and east. The Roanoke River with its headwaters in the mountains to the west flows through the valley, and the metropolitan area providing a natural resource which has been a valuable asset to the growth of the area. Due to the topography and, in some cases, the need to have a water source, the flat areas of the Roanoke River floodplain have become extensively developed. Some of the development is residential, but the majority of the properties are commercial and industrial oriented and suffer severe losses during flood events.

First, new regional incentives for management of the salmon fishery resulted in a request to the Corps of Engineers to evaluate whether modification of flood control criteria might improve the fishery migration. Second, there was need to evaluate and improve in-house operating plans in light of current operating objectives. These factors pointed toward the development of a hydrologic model capable of simulating various combinations of snow and rain scenarios, as well as being able to model the operation of the reservoir system in the basin.

AN - 36389627; 2004 AB - PURPOSE: Dredging of the upper St. Marys River, Michigan and the Duluth-Superior Harbor, Minnesota and Wisconsin is proposed. The Great Lakes-St. Lawrence Seaway commercial navigation system, which this project would affect, serves the heartland of the United States and Canada, providing a maximum safe vessel draft of 25.5 feet at low water datum (LWD). It is anticipated that, unless modifications are made to the existing system, some amount of waterborne commerce would not be able to be serviced in the most economically efficient manner. Under the recommended project plan, the following actions would be implemented: (1) deepening of portions of the upper St. Marys River and Duluth-Superior Harbor to a maximum safe vessel draft of 26.5 feet at LWD; (2) in-water disposal of the estimated 267,600 cubic yards of dredged material from the upper St. Marys River in an environmentally acceptable manner to create an island in Izaak Walton Bay, which would provide habitat enhancement for the Piping Plover, a federally listed endangered species; and (3) upland disposal of dredged material from the Duluth-Superior Harbor in the least costly environmentally acceptable manner. Material dredged from the harbor would be disposed as follows: (1) disposal of an estimated 286,500 cubic yards of dredged material from the Cross and South Channel, West Gate Basin, East Gate Basin, Duluth Harbor Basin Northern and Southern Sections, and Duluth Ship Channel by placing the material in the Lakehead upland site; and (2) disposal of an estimated 129,200 cubic yards of material dredged from the Superior Harbor Basin and Entry Channel by placement of the material in the Itasca upland site. The estimated first cost of the project is $8.1 million at June 1987 price levels. Annual operations and maintenance costs are estimated at $16,000. The estimated federal share of the cost of construction is $5.4 million. The benefit-cost ratio is estimated at 27.5. POSITIVE IMPACTS: Commercial shipping through the Great Lakes and their connecting waterways would be improved substantially due to the ability of vessels to take greater advantage of naturally occurring high-water levels. NEGATIVE IMPACTS: Dredging would increase turbidity of ambient waters and disturb benthic habitat. An increase in vessel draft capacity would result in increased ship-induced bow and stern waves, drawdowns and surges, and propeller-induced sediment disturbances.

AN - 36389544; 2011 AB - PURPOSE: Designation of an ocean dumping site for material dredged from the Houma Navigation Canal of Terrebonne Parish, Louisiana is proposed. The preferred site lies at the gulfward end of the Houma Navigation Canal and has been used for disposal of dredged material by the Army Corps of Engineers since 1964. More specifically, the site is a 1,600-acre underwater tract, running five miles seaward from Cat Island Pass. Approximately 400,000 cubic yards of dredged material have been disposed in the site annually. The site received designation for three years of interim use in 1977. POSITIVE IMPACTS: Site designation would provide an environmentally acceptable means of disposing of material dredged from the canal, ensuring the continued usefulness of the canal for navigational purposes. NEGATIVE IMPACTS: Use of the designated site would result in periodic, temporary increases in turbidity, as well as short-term changes in the grain size of surficial sediments, localized burial of benthic organisms, and temporary mounding of substrate.

AN - 36389675; 2006 AB - PURPOSE: Construction of a levee to protect the village of Liverpool, Illinois from flooding of the Illinois River is proposed. Liverpool is located in Fulton County on the river side of an agricultural levee. The new levee, which would tie into the existing agricultural levee, would be built to allow containment of a 50-year frequency flood; the agricultural levee provides 50-year protection. The plan would include a gravity outlet and a pump station for interior drainage, three road ramps, elevation of a parking area, and approximately 4,395 feet of levee, ranging in height from 3.5 to 17.5 feet. The levee would have side slopes of 3 feet horizontal to 1 foot vertical and would have a top width of 10 feet. The levee would be seeded, and riprap would be placed along the full length of the slope to prevent erosion. The gravity outlet would consist of a 24-inch discharge pipe and a two-acre pond. Since foundation conditions that exist beneath the levee would allow seepage to occur during flood flows, a pump station, consisting of two 4,000 gallons-per-minute submersible centrifugal pumps would be provided to prevent ponding. Gas lines and telephone lines would be relocated as part of the project. Ramps would carry traffic over Exchange, Laurel, and Main streets. The cost of the project is estimated at $1.5 million, including $1.1 million in federal costs and $387,550 in nonfederal costs. The average annual economic costs, including operation and maintenance costs, are estimated at $134,600, assuming an 8.7-percent annual interest rate. The corresponding value of average annual benefits resulting from the plan is estimated at $236,700, for a benefit-cost ratio of 1.8. POSITIVE IMPACTS: Implementation of 50-year flood protection would substantially reduce damages due to flooding from the Illinois River. Frequent severe flooding experienced by the village would be eliminated. The project would allow for revitalization of the community. NEGATIVE IMPACTS: Access to some homes and a public boat ramp would be interrupted temporarily. Approximately 13.5 acres of farmland would be displaced. Floodplain habitat totalling 4.9 acres would be affected by levee construction. Six properties would be displaced due to levee construction. One significant archaeological site would lie within the levee rights-of-way.

AN - 36398084; 2012 AB - PURPOSE: Implementation of plans to mitigate fish and wildlife losses resulting from certain features of the Flood Control Plan for the Mississippi River and Tributaries is proposed for portions of the plan affecting the Yazoo River Basin of Mississippi. Specific projects being addressed in this effort would include the Upper Yazoo Project, Ascalmore Creek-Tippo Bayou Project, Big Sand Creek Projects, and the Panola-Quitman Floodway East Bank Levee. The status of these projects varies from planning stage studies to virtual completion. The study area comprises approximately 1,775 square miles of land and encompasses all or part of some 12 counties in north-central and northwestern Mississippi. Significant environmental problems exist in the area due to the increasing loss of bottomland hardwood forest and the continued decline in wetlands and waterfowl habitat. Tentatively selected mitigation measures include operation of selected project drainage structures to provide for winter flooding for waterfowl, acquisition of land use easements to preserve bottomland hardwood habitat, and installation of waterfowl measures on national wildlife refuges. Land use easements on woodland would require the purchase of 48,800 acres of private woodlands via easements for the right to preserve and then to place 244 small water control structures on purchased land for seasonal flooding. Project drainage structure efforts would consist of operating 35 of the large drainage structures that are located within one of the area's levee systems to provide for seasonal flooding of 17,300 acres of cleared and wooded land; easements would be acquired on 40,800 acres of land to allow for flooding. Waterfowl measures on the national wildlife refuges would provide additional water on cleared and wooded land within the Panther Swamp, Hillside, and Morgan Brake refuges. Measures on Panther Swamp would require additional easements on 4,500 acres of private open land. The total first cost of the tentatively selected mitigation plan is estimated at $41.4 million. Average annual costs are estimated at $1.5 million, based on the authorized discount rate of 2.5 percent and a 50-year economic life for the projects. POSITIVE IMPACTS: Plan implementation would mitigate 146 percent of the terrestrial losses and 100 percent of the waterfowl losses. Fishery losses would be reduced by approximately 1 percent. Bald eagles in the area would benefit from prevention of woodland clearance in some areas due to easement requirements. Approximately 19 other species considered rare by the state of Mississippi would benefit from protective measures. NEGATIVE IMPACTS: The marsh hawk and American kestrel, both of which are considered rare, would suffer somewhat from degradation of habitat.

Preparation date: September 2, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - The Estimation of Rainfall for Flood Forecasting Using Radar and Rain Gage Data AN - 19448426; 7392411 AB - An inadequate knowledge of the magnitude and spatial distribution of precipitation is often a major limitation in developing accurate river-flow forecasts for use in reservoir operations. Digitized weather radar data can provide useful information regarding the spatial distribution of rainfall, although radar-based estimates of rainfall may be in error due to several factors. The use of radar-rainfall data in combination with rain gage measurements may improve rainfall estimate over those based on either form of measurement alone. This improvement is accomplished by adjusting, or "calibrating", radar-rainfall data with data from rain gages situated within the radar "boundary". A set of rainfall analysis software that incorporates this methodology has been developed by the U.S. Army Corps of Engineers hydrologic Engineering Center to aid hydrologists in making real-time water control decisions. The rainfall-analysis software retrieves real-time radar-rainfall data from a National Weather Service RADAP II (Radar Data Processing), and rain gage measurements from data collection platforms via the Geostationary Operational Environmental Satellite (GOES). The radar data from the RADAP II is "calibrated" with the rain gage data using a simple Kriging technique. Subbasin-average rainfall is then computed from the calibrated data and stored in a database file for subsequent use by a river-flow forecast model. Graphics programs aide in the evaluation of the data. This software system has been implemented for a few pilot watersheds in Oklahoma. JF - Technical Papers.

AN - 36408118; 2008 AB - PURPOSE: A flood control plan for Fort Wayne and vicinity, in Allen County, Indiana is proposed. The selected plan provides for upgrading approximately 35,000 feet of levee, floodwall, and steel sheet pile crib along the Maumee, St. Marys, and St. Josephs rivers and Spy Run Creek with new levees and floodwalls, to be constructed only where necessary to tie the system into high ground. The structures would be constructed to the 100-year flood event protection level. The levees would be constructed of local material, with seepage protection on the slopes of the levees. A slurry trench would be constructed under all levee and floodwall lengths to prevent or reduce seepage. The top width would be widened to 10 feet, trees would be removed, and the river side slope would be improved to a minimum of 2 horizontal to 1 vertical. Any slopes steeper than 2.5 to 1 would require slope protection. Construction of the selected plan would raise the 100-year water surface elevation by 0.1 foot at the confluence of the three rivers. A 15,000 gallon per minute pumping station and approximately 6,000 linear feet of storm sewer would need to be installed to allow for interior drainage. Construction would require removal of existing dike and riverbank vegetation, including some large trees. The dikes would be planted with shrubs and grasses following project completion. The estimated first cost of the selected plan is $12.9 million. Estimated average annual benefits resulting from the plan would be $4.2 million, with an average estimated annual cost of $1.3 million. The resulting benefit-cost ratio would be 3.2. POSITIVE IMPACTS: A flood control project at Fort Wayne would have a beneficial impact on community cohesion by eliminating the flood threat that jeopardizes public health and safety and results in excessive property damages. Some property values may be increased but would not appreciably affect tax revenues. Employment opportunities would be generated during construction. NEGATIVE IMPACTS: Because vegetation would be removed from the banks for levee work, fish habitat would be adversely affected, since tree roots, fallen trees, and fallen branches and leaves form excellent fish foraging and escape cover areas. Also, since shade regulates temperatures of nearshore areas, the removal of vegetation would adversely affect temperatures of fish habitat. Riparian habitat would also be lost, as would associated wildlife use, due to levee construction. Major impacts to cultural resources would occur, particularly in downstream sections of the Maumee River. There would be temporary inconveniences due to road closures and other construction-related impacts during work periods. The increased dike height may be aesthetically displeasing to some community members. Construction noise would be especially disturbing to wildlife, and construction activity would increase travel by trucks in the area.

Preparation date: August 30, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GEORGE P. COLEMAN BRIDGE YORK RIVER CROSSING STUDY, YORK AND GLOUCESTER COUNTIES, VIRGINIA. AN - 36400606; 1994 AB - PURPOSE: Construction of a bridge or tunnel and associated approaches to replace the George P. Coleman Bridge across the York River in Virginia is proposed to improve the connection between York and Gloucester counties. The study area for the project includes portions of Gloucester, York, and James City counties and a 20-mile section of the York River. The existing bridge is a two-lane, 0.71-mile facility, with double-swing spans, crossing the York River in southeastern Virginia at Yorktown. It is the only York River crossing south of West Point, a community 30 miles upriver. The project would consist of a limited-access, four-lane facility, with interchanges at major intersecting roads and a design speed of 60 miles per hour (mph) for bridge alteratives and 50 mph for tunnel alternatives. The northern terminus of the project would be Route 17 in Gloucester County and the southern terminus, depending on the alterative chosen, would be either Interstate 64 (I-64) or Route 17 in York County. The relative impacts of implementing seven build alternatives are under consideration, based on traffic, engineering, and environmental factors within the project study area. The facility, either a bridge or a tunnel, would provide for minimum lane widths of 12 feet and require a typical rights-of-way width of 250 feet. Interchanges would be constructed at the project termini. The estimated costs of the seven construction alternatives range from $67 million for reconstruction of the existing bridge to $376 million for tunnel construction. POSITIVE IMPACTS: Bridge construction would expand the vehicular capacity for crossing the York River in the vicinity of the existing George P. Coleman Bridge. The project would thereby alleviate current traffic congestion at the crossing, accommodate projected river crossing traffic to the year 2010, and ease travel between the Tidewater peninsulas; travel between the peninsulas is critical to the continued social and economic health of the region, which includes the rural outlying counties of King and Queen, Middlesex, and Mathews, and the urbanized areas of James City, Hampton, Newport News, and Norfolk. NEGATIVE IMPACTS: Rights-of-way requirements would displace as many as 33 families, 172 individuals, and 9 businesses. A portion of the local property tax bases would be lost, and residential, commercial, agricultural, industrial and other lands, possibly including parklands, would be lost. The number of residences affected by traffic noise could increase along the Route 17 corridor. Wetlands would be impacted, and hazardous waste sites could be affected. Numerous historical and archaeological sites could be damaged.

AN - 36398166; 2005 AB - PURPOSE: Provision of navigation improvements in Kaulana Bay east of South Point on the island of Hawaii is proposed. This supplement to the final environmental impact statement of September 1981 has been filed because of delays in initiating the project, based on litigation against the Corps of Engineers, which acted as the federal administering agency, and the Hawaii Department of Transportation, the local sponsor. The litigation was filed in October 1983 and settled in March 1988. Subsequently, the Corps was requested by the local sponsor to restart the project and reinitiate the process for awarding construction of the approved navigation improvements. Although there have been no changes in the selected project design and previously documented, expected impacts, it has been determined that a supplemental statement should be submitted to provide a record of the measures to be taken. The preferred design would consist of a 135-foot-long, 8.5-foot-deep entrance channel with a width tapering from 80 feet to 60 feet, a 200-foot-by-100-foot turning basin, and a 155-foot-long breakwater with a crest elevation of 11.5 at the head and 8.5 feet at the trunk. The turning basin would have a depth of 6.5 feet. Approximately 5,200 cubic yards of dredged material would be disposed via spreading on a 6.4-acre site adjacent to a launch ramp associated with the breakwater. The only navigational aids to be installed would consist of a day marker. The state of Hawaii would be responsible for the installation of all shoreside facilities, including 40 to 50 parking spaces and toilet and freshwater facilities. POSITIVE IMPACTS: The project would improve the usability and safety of the boating facilities in the bay that are used by South Point commercial fishing interests. The breakwater would offer protection to a launch ramp that would otherwise be subject to wave action generated by deep water swells and trade winds. The total catch by commercial fishing interests would increase substantially. NEGATIVE IMPACTS: The breakwater could damage surface archaeological sites on the east side of the bay, and actions related to the construction of the breakwater could destroy other sites and cultural materials in the area. Construction activities would disturb 0.91 acre of bay habitat.

Preparation date: August 20, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GALVESTON BAY AREA NAVIGATION STUDY AND FEASIBILITY REPORT, GALVESTON, TEXAS. AN - 36406648; 2093 AB - PURPOSE: Implementation of a plan to improve navigational efficiency on the Houston Ship Channel, its ancillary channels, and the Galveston Channel in Harris and Galveston counties, Texas is proposed. This study, along with a similar study of the Texas City Channel already completed, is being accomplished under the Comprehensive Galveston Bay Area Navigation Study. The authorized enlargement of the Texas City Channel to 50 feet by 600 feet is assumed to be in place for this study. The Houston Ship Channel is presently 40 feet deep by 400 feet wide. The preferred plan would involve: (1) a 50- by 600-foot channel from Bolivar Roads (confluence with the Texas City Channel) to Boggy Bayou (Shell) in Houston; (2) a 40- by 400-foot intermittent channel from Boggy Bayou to Clinton Island; (3) a 25- by 200-foot channel along both sides of the Galveston Channel juncture to the 25-foot contour offshore; (4) an easing of the bend at the Bolivar Peninsula side of the Gulf Intracoastal Waterway-Houston Ship Channel junction; (5) a 50- by 450-foot channel at Galveston extending from Bolivar Roads for 3.6 miles to the existing grain elevators; (6) improvements to navigation aids, including larger range markers, an improved system of marking turns, and, possibly, the installation of an electronic position location system; and (7) development of two confined dredged material disposal areas in the northern part of Galveston Bay and seven unconfined disposal areas in the lower bay. In addition, the selected plan would include federal assumption of maintenance dredging on Carpenters Bayou, an ancillary channel for the Houston Ship Channel. Project mitigation measures would include development of 859 acres of artificial oyster reefs. The first cost of plan implementation is estimated at $352.6 million in 1987 dollars. Operation and maintenance costs are estimated at $1.55 million per year. The benefit-cost ratio is estimated at 2.4. POSITIVE IMPACTS: Enlargement of the channel would allow for use of larger, more efficient vessels. Greater width and bend easings would allow the use of larger ships without depth increases. Vessel safety would be improved as well, since the use of larger vessels would reduce the number of vessel trips required and, hence, the number of opportunities for accidents. The number and duration of vessel delays would also decline. Annual benefits redounding from the project would be worth $47.9 million. NEGATIVE IMPACTS: Bay salinity during certain inflow conditions could be increased by 1.2 parts per thousand. Hurricane surge and oil spill changes could result in small and generally insignificant effects. Cultural resources along the channels could be disturbed. Dredging would increase turbidity temporarily in localized areas. Channel widening and construction of the dredged disposal areas would displace habitat. Shrimp and fin fish production would decline periodically due to dredging and disposal operations.

Preparation date: August 19, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MIAMI HARBOR CHANNEL, FLORIDA: IMPROVEMENTS FOR NAVIGATION. AN - 36404763; 2002 AB - PURPOSE: Improvement of Miami Harbor in Biscayne Bay, Florida is proposed to provide increased depths in the existing federal and locally created channels. Biscayne Bay is a shallow salt water sound on the Atlantic coast near the southern end of the Florida peninsula. The immediate tributary area for Miami Harbor is Dade County, which depends on the port for some basic commodities. The recommended project would involve modification of the harbor to provide a channel 41 feet deep and 500 feet wide from the open ocean to the existing beach line. The channel would reduce to 39 feet deep and 400 feet wide at the beach line and remain at those dimensions to the Fisher Island turning basin. The project would also include deepening the South Lummus Island channel to 39 feet over a bottom width of 400 feet from the Fisher Island turning basin to the west end of the four container berths at Lummus Island; this channel would terminate at a turning basin centered around the existing Lummus Island turning basin. The turning basin would be dredged to a depth of 39 feet and would have a diameter of 1,600 feet. All dredged material would be dumped in the Miami Ocean Dredged Material Disposal Site, which is presently undergoing final designation for use by the Environmental Protection Agency. The first cost of the project is estimated at $35.74 million; increases in annual maintenance costs are estimated at $5,000. Annualized values of benefits and costs are estimated at $4.5 million and $3.1 million, respectively, and the benefit-cost ratio is estimated at 1.4. POSITIVE IMPACTS: Planned improvements would allow vessels to call at the harbor with increased draft and tonnage, resulting in transportation savings to shippers. NEGATIVE IMPACTS: Because most of the dredging would be done within the existing channel, where periodic disruptions from maintenance dredging and ship movements have not permitted the establishment of a diversified fauna, adverse environmental impacts would be restricted to seagrasses at the turning basin and impacts associated with blasting. The loss of marine seagrasses would be restricted to newly dredged areas of the Dodge-Lummus turning basin; the affected area would extend over 35 acres. Although seagrasses in the area are sometimes fed upon by manatees, it is unlikely that this endangered species would be seriously affected. Offshore disposal would result in cumulative impacts in the disposal area in that disposal would retard development of biota in the area.

Preparation date: August 19, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WIDENING AND EXTENSION OF BEAVER DAM ROAD FROM BEAVER COURT TO PADONIA ROAD, BALTIMORE COUNTY, MARYLAND. AN - 36404312; 1904 AB - PURPOSE: Widening and extension of Beaver Dam Road to create a four-lane facility from Beaver Court to Padonia Road in Baltimore County, Maryland is proposed. The existing two-lane section of Beaver Dam Road would be widened to four lanes from the southern limit of Hunt Valley Industrial Park at Beaver Court to just north of Church Lane, and a new four-lane roadway would be constructed from Church Lane to Padonia Road. The project would also involve provision of an intersection with the proposed Warren Road extension; provision of a connection between Industry Lane and Beaver Dam Road; improvement of the intersection with Church Lane or closure of Church Lane; and creation of an intersection with Padonia Road. Under the preferred alternative, the intersection of Padonia Road would be opposite the intersection of Deereco Drive. CONRAIL maintains a 56-foot-wide right-of-way and a single track through the corridor. Acquisition and development of a public transportation facility along the CONRAIL rights-of-way is still under consideration. Under the preferred alternative, the existing CONRAIL lines would be relocated east of their present location, outside the existing rights-of-way. The estimated cost of the project, including construction, relocation, and rights-of-way costs, is estimated at $8.7 million. POSITIVE IMPACTS: The widening and extension of Beaver Dam Road would permit improved movement of traffic along the corridor and would provide additional access for traffic from the Hunt Valley complex to Interstate 83 (I-83) via Padonia Road. The project would provide a connection with Industry Lane, allowing additional traffic movement away from York Road. Beaver Dam Road would help alleviate the traffic congestion along York Road and would provide an upgraded intersection with the proposed extension of Warren Road from York Road to I-83. Access to industrial and commercial properties within the corridor would be improved, allowing for commercial expansion. This would provide increased employment and additions to the tax base. NEGATIVE IMPACTS: The preferred alternative would affect a proposed historic district. Five historic residential structures would be displaced. One major stream crossing would be required, involving the construction of a bridge or two 12-by-16-foot box culverts and relocation of 325 feet of Goodwin Run, a degraded class III stream. Approximately 0.06 acre of wetland and 1.6 acres of floodplain would be affected, and approximately 0.5 acre of prime farmland would be displaced. A total of five residences housing 12 persons and 1 business would be displaced. Federal Highway Administration Noise Abatement Criteria would be violated at two receptors.

Preparation date: August 17, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ROCK CREEK/MUDDY CREEK RESERVOIR, ROUTT AND GRAND COUNTIES, COLORADO (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1987). AN - 36400180; 1926 AB - PURPOSE: Construction of a water storage reservoir, located in Grand County in western Colorado, is proposed. During review of the draft environmental impact statement, two projects were considered, namely, the Rock Creek Reservoir in the Routt National Forest and Muddy Creek Reservoir in the Kremmling Resource Area. This supplement to the draft environmental impact statement of August 1987 provides additional analysis of the potential reservoir development at the two sites and proposes the Muddy Creek site for project development. The Muddy Creek project site would be located just west of Wolford Mountain (five miles north of Kremmling, Colorado). The Muddy Creek Dam would be a zoned earthfill dam, with a dam crest located 120 feet above the present streambed. The dam would contain approximately 997,200 cubic yards of fill; the majority of this material would be obtained from borrow areas immediately upstream and downstream of the damsite, resulting in a haul distance of less than one mile. Approximately 42,800 cubic yards of riprap material would have to be hauled 40 miles from a quarry to the east of the project site. An additional 76,700 cubic yards of materials for filters, drains, and concrete aggregate could be supplied by a firm in Kremmling. It would create a 60,000-acre-foot capacity reservoir, which would include 4,000 acre-feet of conservation storage and 6,000 acre-feet of sediment storage. Annual water yield would amount to 23,000 acre-feet. The reservoir would have a surface area of 1,447 acres and extend 5.5 miles up Muddy Creek. The dam would feature a multiple outlet. During construction, Muddy Creek would be diverted through a conduit located on the right side of the streambed. Relocation of a portion of U.S. Highway 40 and two electric transmission lines would be required. A campground and picnic area would be developed in association with the reservoir. The estimated cost of the project is $25.8 million. POSITIVE IMPACTS: The Muddy Creek Reservoir would primarily be a source of augmentation water. Reservoir operations would fulfill primary demands under the Metro Denver Lease, including provision of water for the Middle Park Water Conservancy District. Releases would be made in exchange for water stored in the Green Mountain Reservoir. Beneficial impacts would include increased recreational use of the reservoirs and associated campgrounds, reservoir fish habitat, and the economic benefits of the recreational use. Releases from the reservoir could also enhance the cold water trout fishery in the tailwater of the dam. Construction activities would result in significant increases in area employment rolls. NEGATIVE IMPACTS: The dam and reservoir would displace 822 acres of farmlands. The potential for fogging in the vicinity of the project site would increase. Endangered fish species would be impacted. The area would undergo a long-term social change due to the reservoir and associated development, and would impact wetlands, a candidate federal rare plant, big game habitat (elk and deer), and visual resources.

AN - 36402837; 1872 AB - PURPOSE: Construction and operation of a new regional medical training hospital and outpatient clinic, with appropriate support facilities and services, at Fort Sam Houston, Bexar County, Texas are proposed to replace the existing Brooke Army Medical Center (BAMC). The second largest U.S. Army medical center and one of the five major tenants of Fort Sam Houston, BAMC presently includes a 649-bed hospital facility and provides for approximately 835,000 outpatient visits annually, as well as some 296,000 visits for inhalation /respiratory, occupational, and physical therapy and rehabilitation. The center is composed of 52 structures, with some of the buildings dating from the early twentieth century. The preferred alternative for replacement of the center would involve construction and operation of a new 450-bed facility by the Joint Military Medical Command-San Antonio. Inpatient services would include 10 intensive care unit beds; 10 coronary care unit beds; 20 surgical intensive care unit beds; 24 coronary care stepdown unit beds; 22 thoracic surgery stepdown beds; 262 beds for medical, other surgical, and obstetric/gynecological care; 30 psychiatric care beds; 32 pediatric care beds (including beds assigned to the pediatric intensive care unit); 40 beds assigned to the Institute of Surgical Research; and 18 obstetrical care beds. Center staff would include 1,600 civilian personnel and 1,628 military personnel. The center's facilities would encompass 1.3 million gross square feet. The project would be a component of an overall 1,200 Bed Joint Venture Military Medical Community in the San Antonio area. The estimated cost of the 450-bed center is $282.0 million. POSITIVE IMPACTS: Centralization of the facilities, now spread out in numerous, and often outdated structures, would vastly improve the delivery of services rendered by the medical center. Cost savings would be realized in the areas of personnel time and energy expenditure. Construction expenditures would add significantly to the local economy. Overall health care in the catchment area of the center would benefit significantly as transit time for patients decreases and modern facilities become available. The scenic and visual environment of the fort grounds would be improved significantly due to replacement of dilapidated buildings. NEGATIVE IMPACTS: During construction, traffic patterns, air and water quality, soils, and the solid waste collection/disposal services would be impacted. Construction activities would also increase ambient noise levels.

AN - 36402789; 1920 AB - PURPOSE: Upgrading of the Metropolitan District Commission (MDC) wastewater management systems, including sewer interceptors, wastewater treatment facilities, and sludge disposal facilities, in Boston, Massachusetts is proposed. This supplement to the final environmental impact statement (EIS) of December 1985 on the upgrading project addresses the impacts of the wastewater conveyance system for the Greater Boston wastewater treatment facility. The final EIS recommended treatment of wastewaters from the entire Metropolitan Sewerage District service area at a centralized location at the Deer Island Plant. The plant would be expanded and upgraded to provide secondary treatment for an average daily flow of 586 million gallons. The final EIS on siting a secondary treatment facility for the harbor designated an area east of Deer Island for the discharge of effluent. The area had to be more precisely defined for evaluation in this final supplemental EIS. This was done by establishing a limited area in Massachusetts Bay suitable for discharge of effluent from the secondary treatment plant on Deer Island. A landward or western boundary was established beyond which shoreline impacts could be avoided by minimizing transport of effluent to the shoreline, and water quality criteria goals could be achieved by providing a minimum initial dilution. The eastern or seaward edge of the area could not easily be established by application of a single criterion. The impacts from factors of concern, such as sediment, water quality, and marine ecosystems, generally decrease along the gradient in an offshore direction. Costs increase along the same gradient. Therefore, a screening level analysis was performed comparing a secondary discharge at the nearshore and offshore regions. Three sites were identified for detailed evaluation. For approximately five years, while the secondary treatment plant is under construction, primary effluent would be discharged. The discharge location of interim primary effluent was also addressed in the screening analysis. The discharge conveyance system, proposed in this final supplement, would consist of deep rock tunnels for the interisland and outfall conduits and a diffuser located at least seven miles east of Deer Island. In addition, a conduit would be constructed to deliver South System flows from Nut Island to the Deer Island Plant to effect consolidation of wastewater treatment for the entire service area. The estimated cost of the conveyance and outfall structures ranges from $276 million to $468 million. POSITIVE IMPACTS: Offshore release of primary and secondary effluent from the Deer Island facility would be, environmentally and economically, the most acceptable means of dealing with effluent from the treatment plant. NEGATIVE IMPACTS: Some effluent from the outfall would be transported back to the shoreline by currents, impacting recreational and other shoreline activities. Dredging associated with construction of the tunnel would result in disturbances of bay benthos and temporary turbidity. Some polychlorinated biphenyls would be released into the water column of the bay during outfall operation. Water quality standards for aquatic life and public health would be exceeded on occasion, and sediment enrichment would occur.

AN - 36381986; 1877 AB - PURPOSE: Implementation of the Hercules Project to develop oil and natural gas resources in state tidelands in the Santa Barbara Channel off Santa Barbara County, California is proposed. Project facilities would include an offshore platform, onshore processing facilities at Canada de la Huerta, and offshore and onshore pipelines between the platform and the onshore facilities. All facilities would be sited along the coast, just east of Gaviota and almost 30 miles west of Santa Barbara. More specifically, the major components of the project as proposed by the applicant (Shell Western E&P Inc.) would include the Hercules Platform located 2.5 miles offshore and approximately 4.0 miles southeast of Gaviota in 238 feet of water; modification of the Molino sweet gas processing facility in Canada de la Huerta to allow it to process as much as 100 million cubic feet per day; construction of new oil and sour gas processing facilities immediately to the north of the existing Molino facility; installation of six new pipelines (bundled together) to connect the platform with onshore processing facilities; construction of a 7.4-megawatt cogeneration facility in Canada de la Huerta with a power cable extending to the platform; construction of a new electrical substation and power lines to supply supplemental electricity from Southern California Edison; and the addition of water treatment facilities and an associated ocean outfall, fresh water wells and treatment facilities, three oil storage tanks (60,000-barrel total capacity), and new propane gas liquids and sulfur storage and loading facilities, all at Canada de la Huerta. The platform would consist of three decks and 64 well slots. The six new pipelines would include three lines to carry oil produced water, sour gas, and sweet gas from the platform to the onshore facilities and three pipelines to carry brine, glycol, and fresh water to the platform. The pipelines would extend from the platform to the landfall at Arroyo Hondo, then eastward approximately 0.6 mile to the Canada de la Huerta site. Project construction would begin in early 1990, and project completion would be scheduled for mid-1991. Drilling operations would begin in 1991, and production would commence shortly thereafter. Drilling and production would extend over four to six years, and production would continue over 14 to 16 years beyond the end of the drilling and production period. POSITIVE IMPACTS: Project implementation would result in the production of as much as 15 and 85 million cubic feet of sour and sweet natural gas, respectively, and 30,000 barrels of oil per day. As a result, the local and regional economy would be boosted significantly, and the national economy as a whole would be less dependent on foreign sources of oil. Employment during the operation phase would be 86 persons during the drilling and production period and 36 persons thereafter. NEGATIVE IMPACTS: Development and operation activities would result in topographic modifications to land and seafloor areas; violation of air quality standards; potential oil spills into surface waters and salt marshes; potential releases of toxic gases in riparian and woodland areas; possible fires in riparian and woodland areas; and potential spills of natural gas liquid or liquid petroleum gas during transport. Additional facilities at Canada de la Huerta would displace three acres of land.

Relating contaminant uptake and mobility by the index plant grown on dredged material to that of an existing agricultural data base may show that levels of contaminant uptake by plants and subsequent mobility into the food web from dredged material may be compared to what is normally acceptable in agricultural products. Therefore, contaminant uptake and mobility may not be as harmful to the environment as often projected (i.e., absence of unacceptable adverse effect).

The last significant change in the water resources planning process and program occurred in the 1970s, as a result of the increased focus on the environment. We are now in the midst of yet another major change. With enactment of the Water Resources Development Act of 1986 (WRDA '86) certain changes were mandated, others were permitted, and others are deemed necessary as a result of various other provisions within the Act. The Act required more cost sharing by non-Federal interests and placed statutory time limits and cost sharing requirements on Corps planning. To respond to the challenges of the Act, improvements in the budgetary process have been made to allow continuous funding through the planning and design efforts. This effort with other management inprovements will facilitate a reduction in the Corps project development and implementation process. In response to WRDA '86 changes in the planning process and program have been instituted, which have and will continue to impact significantly on the development of water resources projects. This paper provides an overview of the current planning process and program, and highlight changes that have occurred since enactment of WRDA '86.

When study initiation, funding levels and scheduling are developed without sufficient coordination among the planning and technical elements, inefficiencies are introduced. The result is an unproductive use of time and effort in redefining the previously uncoordinated tasks, schedules and funding after the study has been initiated.

The time and funds available to conduct reconnaissance phase studies are limited. Policy concerning the scope, reliability, confidence, and management of the technical analysis, which serves as the foundation for scoping and estimating the cost of the feasibility report, should be clearly established. The management of studies using a "study team" concept has been promoted within the Corps for several years. Experience shows the success of this concept depends greatly on the personality of the study manager. This year the Corps is implementing the "project management" concept for Civil Works studies utilizing independent life cycle and team project managers. Thought must be given to how this new concept will change the way the Corps does business. Other areas of interest in the management of reconnaissance studies concern the functional responsibilities and interaction between organizational elements. They are apparently not consistent between Districts or even within a District. Experiences and opinions concerning the involvement of hydrologic engineering staffs in reconnaissance studies are discussed in this paper including forces at play today which require an even greater involvement of the hydrologic engineers earlier in the reconnaissance phase. Recent experience in seven reconnaissance studies in the Omaha District is discussed as well as the results of a survey of hydrologie engineers throughout the Corps.

AN - 36401222; 1934 AB - PURPOSE: Implementation of flood control and major drainage works on Gills Creek in Richland County, South Carolina is proposed. Gills Creek basin, which lies in the eastern portion of the Columbia metropolitan area, has a long history of flooding, including several dam failures. Four floods occurred over the past 10 years. The average annual damage resulting from flooding within the basin is estimated at $1.7 million. The selected flood control plan would involve construction of a dry reservoir on Gills Creek, to be located near Boyden Arbor reserve center in the Fort Jackson Military Reservation. An earth embankment detention structure would be constructed across Gills Creek at Boyden Arbor Pond on Fort Jackson property. The spillway would be cut out of the right abutment. Boyden Arbor Dam Spillway would be removed to an elevation of 192 feet above the National Geodetic Vertical Datum so that excavation of a downstream channel would not be necessary for required tailwater depths on the new dam. The low-level outlet structure would consist of a six-foot-diameter pipe equipped with a valve. The valve would be set to nondamaging flows for daily use and could be opened to drain the reservoir after high flood events had passed. The low-level outlet would discharge into a preformed stilling basin. The Gills Creek site would be cleared in the vicinity of the dam and spillway for construction access. Boyden Arbor Road, located on Fort Jackson above the proposed dam, would be flooded as a result of the construction of the dam; the road would be relocated across the crest of the dam in lieu of being raised. The estimated first cost of the plan is $6.7 million, of which $3.8 million would be funded by the Federal Government. Annual charges are estimated at $691,000, while annual benefits are estimated at $848,600, resulting in a benefit-cost ratio of 1.2. POSITIVE IMPACTS: The dam and related structures would protect downstream areas against the 100-year-frequency storm. The dam would allow for control of sediment as well as flood flows. As a result, downstream water quality would improve somewhat. Property values and growth rates along downstream reaches would increase due to flood protection. NEGATIVE IMPACTS: Approximately 20 acres of pine and hardwood forest would be cleared for spillway and dam construction. The recommended plan has not been accepted by all local interests.

Preparation date: July 22, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DIAMOND CHUITNA COAL PROJECT, SOUTHCENTRAL ALASKA. AN - 36402881; 1874 AB - PURPOSE: Issuance of a permit to the Diamond Alaska Coal Company is proposed for development of the Diamond Chuitna Coal Project, to be located on the west side of Cook Inlet in southcentral Alaska. The project would consist of a surface coal mine, haul road, a means of transporting coal to a port facility on Cook Inlet, dock facilities, and other ancillary facilities. The preferred alternative would involve construction of a port site at Ladd, development of an eastern transportation corridor, development of a housing facility at Lone Creek, and installation of a conveyor system that would parallel the haul road and transport coal to the port site. Full development of the Diamond Chuitna coal project would involve a 10.9-million-metric-ton (12.0 million short tons) per year surface coal mine in the Beluga area, approximately 72 kilometers (45 miles) west of Anchorage. Coal to be mined would be subbituminous, low-sulphur, low-ash, high-moisture steam coal with an average of 4,250 kilocalories per kilogram (7,650 British thermal units per pound). The actual area to be mined during the projected 34-year life of the project would cover approximately 2,029 hectares (5,014 acres), with a maximum of 182 hectares (450 acres) of pit being open at any one time. Mining methods would involve the use of shovels, draglines, hydraulic backhoes, front-end loaders, and haul trucks. Coal would be crushed at the mine and carried to a 22-hectare (55 acres) mine service area by conveyor for further crushing and weighing. The coal would then be transported approximately 11 miles by a single-span, 48-inch-wide conventional conveyor to a port site on Cook Inlet, located either at Granite Point south of the mine or at Ladd east of the mine. The conveyor would be paralleled by a light-duty maintenance road and an all-weather gravel access/haul road. The onshore port facilities would occupy approximately 121 hectares (300 acres) on the bluff above Cook Inlet at either Granite Point or Ladd. As much as 1.1 million metric tons (1.2 million short tons) of coal would be stockpiled at the port for shipment. At full production, the offshore port facility would consist of an elevated trestle up to 3,810 meters (12,500 feet) long, and would support twin conveyors for loading coal ships. The work force would be housed in permanent single-status housing and community facilities on an 8 hectare (20 acres) site north of the Chuitna River. The project would include a reclamation plan. Although placement of the onshore port facilities at the Ladd site is the primary preferred alternative, a site at Granite Point could be chosen, due to potential conflicts resulting from a transport corridor crossing of Tyonek Native Corporation land if the Ladd alternative is chosen. POSITIVE IMPACTS: Coal produced by the project would assist in providing for the energy needs of the local area and the region. Increases in employment and other socioeconomic enhancements would benefit the local economy. NEGATIVE IMPACTS: Project components would disturb approximately 2,029 hectares (5,014 acres) of vegetated terrain. Due to ongoing reclamation of mined areas, the actual unvegetated surface at any one time would be substantially less. Approximately 24 percent of the area that would be disturbed is classified as wetlands. Wildlife impacts would include the loss of habitat during the life of the mine and for a period following termination of mining activities. Moose, brown bear, and black bear would be affected, as well as small mammals and birds. The loss of moose winter range at the proposed port site and a portion of a rutting area in the vicinity of the mine would also occur. Movement of large animals would be impeded by the conveyor system. Loss of fish productivity, including productivity of such key species as chinook and coho salmon, would occur during the mining operation. The return of mined-out streams to their original condition would be problematic. Some disruption of subsistence activities would be likely.

Preparation date: July 18, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SECOND LOCK AT LOCKS AND DAM NUMBER 26 (REPLACEMENT), MISSISSIPPI RIVER, ALTON, ILLINOIS AND MISSOURI. AN - 36397122; 1927 AB - PURPOSE: Construction of a 600-foot second lock at Locks and Dam No. 26 (Replacement) on the Mississippi River near Alton, Illinois is proposed. Under the preferred alternative, the second lock (600 feet by 110 feet) would be constructed between the authorized lock and the Illinois bank. The concrete-and-steel lock would be placed on foundation piling. The staging area would be on the Illinois bank adjacent to the construction site and riverside of the levee. A portion of the area was built to an elevation of 434 feet National Geodetic Vertical Datum (NGVD) during construction of the first lock and is approximately 18 acres in size. If additional area is required for staging, the contractor could either use areas in Missouri remaining from construction of the first lock that would not be inundated by the new pool or work from barges in the river. A cofferdam would be created to allow for construction of the second lock. Following completion of the second lock, the cofferdam would be removed and sand from the cells would be dumped on the Missouri side of the river. Some material would be needed to build up the Illinois bank to create an esplanade. Due to the depth of the channel on the Illinois side of the river, foundation restoration would be required prior to construction of the lock. POSITIVE IMPACTS: Operation of the lock would increase commercial river traffic significantly. Traffic levels would reach 174 million tons by 2020, representing a 25 percent increase over current levels. Average annual national economic development benefits would amount to $152 million. The additional lock would function as a backup for the existing lock, reducing the possibility of delays due to lock failure. NEGATIVE IMPACTS: The rise in river traffic would result in increased erosion, suspended sediment, and backwater sediment. Backwater recreational opportunities would be decreased due to sedimentation, and bank erosion and impoundment drawdowns would damage cultural resource sites. National wildlife refuges and other wildlife habitat would be damaged in some areas, degrading commercial and sport fishing, waterfowl hunting, and furbearer trapping.

Preparation date: July 15, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SOURIS RIVER BASIN PROJECT, SOURIS RIVER, RENVILLE, WARD, McHENRY, AND BOTTINEAU COUNTIES, NORTH DAKOTA. AN - 36404037; 1933 AB - PURPOSE: Implementation of a flood control project for urban and rural reaches of the Souris River in North Dakota and Saskatchewan, Canada is proposed. The project would be developed and operated jointly by the United States and Canada and would involve the purchase of flood storage capacity in Alameda and Rafferty reservoirs in Saskatchewan, operation of a diversion channel from the Boundary Reservoir to the Rafferty Reservoir to minimize peak flood flows on the Souris River below Long Creek, and modification of the gated outlet at the Lake Darling Dam. The Rafferty Dam, which would lie six kilometers northwest of Estevan on the Souris River, would be a homogeneous earthfill structure with an elevation of 550.5 meters that would inundate 12,050 acres. The maximum flood pool would have an elevation of 554 meters, a volume of 513,000 acre-feet, a surface area of 15,400 acres, and a length of 41 miles. The primary purpose of the Rafferty Reservoir would be to provide cooling water for the Shand Thermal Station. In addition to its function as a cooling reservoir and flood storage impoundment, the Rafferty Reservoir would provide municipal water for Weyburn and Estevan and irrigation water for agricultural lands. Construction of the Rafferty Dam would commence in the spring of 1988 and end in the fall of 1989. The Alameda Dam, which would lie 15 kilometers upstream of the confluence of Moose Mountain Creek with the Souris River, would be an earthfill structure creating a reservoir with a maximum flood pool elevation of 579 meters, a flood pool volume of 111,600 acre-feet, and a flood pool surface-area of 5,470 acres. The maximum flood pool would extend 15 miles. In addition to flood control storage, the Alameda Reservoir would provide recreational opportunities, municipal water supply, and irrigation for agricultural lands. The Alameda Dam would be constructed over two construction seasons beginning in 1989. The existing Boundary Dam and Reservoir, which is used to cool a thermal electric plant and to provide municipal water to Estevan, would be relieved via a diversion channel leading to Rafferty Reservoir when peak spring flood flows are anticipated. Modifications at the Lake Darling Dam would consist of replacing the existing low-flow outlet works with a new conduit to allow for operation of the dam for flood control purposes. Minor structural components to be implemented in association with operation of the project would include urban levee improvements; relocation; ring levee protection or elevation of rural residences affected by flooding; and purchase of flowage easements. Mitigation of wildlife habitat impacts due to project structures and operations would consist of improvements to refuge water control structures, spillways, and dams. Evaporation-sharing arrangements between Saskatechewan and North Dakota would be included in the project plan. The estimated cost of the project is $73.7 million, and the benefit-cost ratio is 1.8. POSITIVE IMPACTS: Operation of the project, which would be completed in 1991, would provide water supply and flood control benefits to Saskatchewan, provide 100-year flood protection benefits to the city of Minot, North Dakota, and significantly reduce flood damages along the main stem of the Souris River in North Dakota. Average annual benefits would be worth $7.3 million. NEGATIVE IMPACTS: During nonflood years, the project would increase agricultural and livestock encroachment and encroachment of upland plant species on low-lying wetlands, floodplain forests, and grasslands. The potential for water shortages and avian disease problems within national wildlife refuges would increase somewhat. During flood years, the project could result in some conflicts related to regional water supply. Inundation of new land areas due to storage of flood waters could reduce water quality in some surface flows. Preflood drawdown of reservoir waters could increase winter-kill of aquatic resources in Lake Darling and the Souris River. Prolonged flooding during flood years would result in losses of grasslands, wetlands, floodplain forests, farmlands, and associated wildlife habitat, including refuge habitat.

AN - 36389000; 1922 AB - PURPOSE: Improvement of the Bayou La Batre navigation channel in southern Mobile County, Alabama is proposed. The preferred plan would provide a 14- by 75-foot channel from the turning basin to the Highway 188 bridge, a 12- by 75-foot channel for a distance of 1,500 feet above the bridge, a 14- by 50-foot channel in Snake Bayou from its junction with Bayou La Batre for a distance of 500 feet then 12 by 50 feet for a distance of 800 feet, an 18- by 100-foot channel south from the turning basin to the mouth of the bayou, and an 18- by 120-foot channel from the mouth of the bayou into Mississippi Sound to the Gulf Intracoastal Waterway (GIWW). Dredged material disposal would be accomplished via establishment and use of a 107-acre upland disposal area and use of the existing 70-acre disposal area, establishment of an emergent berm along the northeastern shore of Isle aux Herbes, direct placement in water more than 12 feet deep in Mississippi Sound, and placement of material in an area 5,000 feet south of the GIWW channel. The annualized cost of the project is estimated at $2.1 million, and the benefit-cost ratio is estimated at 2.19. POSITIVE IMPACTS: Enlargement of the channel system would improve the historical status of the Bayou La Batre area as a major fishing port on the Gulf coast. Recent development of the boat-building industry within the area would be supported. More specifically, the project would promote increased diversity of the fishing fleet using the harbor, economic efficiency of the interactive system of vesels and facilities, improved navigational safety, and acceptable disposal of dredged materials. The environmental quality of the bayou and the Mississippi River would be maintained or enhanced. Placement of dredged materials as proposed would promote habitat development and erosion control. NEGATIVE IMPACTS: Dredging and disposal would result in turbidity, temporarily lowering the water quality and destroying benthos. Development induced by the enlarged channel capacity would result in the destruction of wetlands.

AN - 36403295; 1915 AB - PURPOSE: Widening and realignment of 22 miles of U.S. Highway 189 between its junctions with Utah Route 52 and U.S. 40 in Utah and Wasatch counties, Utah are proposed. This draft environmental impact statement supplements the final environmental impact statement of September 1979 on improvement of roads between the junction of Utah Route 52 with Interstate 15 (I-15) in Orem on the west and the intersection of U.S. 189 with U.S. 40 approximately 0.5 mile south of Heber City on the east. A five-mile section of the 25-mile overall route, from the western terminus to Murdock Diversion in Provo Canyon, has been improved to a four-lane facility. Alternatives under consideration for the present project include: (1) addition of shoulders and left-turn lanes; (2) construction of a full four-lane divided highway section; and (3) construction of a four-lane divided section with a median and minimum pavement and clear zone widths. POSITIVE IMPACTS: Proposed roadway improvements would enhance the capacity and safety of the highway while maintaining the recreational and aesthetic qualities of the canyon. Road realignment would correct substandard geometry to meet current design criteria. Access to developed recreation facilities in Provo Canyon and Heber Valley would be improved significantly, and turnouts would be provided for use by sightseers. NEGATIVE IMPACTS: Rights-of-way requirements would displace 70 to 358 acres of land and could result in displacement of one housing unit and three or four businesses. From 44 to 73 receptors would sustain noise impacts, and 65 to 306 acres of terrestrial habitat would be impacted. Although 6 to 12 acres of wetlands would be impacted by the project, all of this habitat would be replaced at other sites. Approximately 1,530 feet of Provo River would require relocation, and the river would be affected by one to seven river crossings. One archaeological site eligible for inclusion in the National Register of Historic Places, one to three public parks, and one recreation area could be affected by the project. As little as 1.0 acre and as much as 162.22 acres of public parkland would be required for rights-of-way. Fisheries could be damaged by construction of earthworks, retaining walls, and bridge structures along 900 to 8,700 linear feet of riverbank.

AN - 36406682; 1936 AB - PURPOSE: Designation of ocean dumping sites for disposal of material dredged from the Phase I study area of the Puget Sound Dredged Disposal Analysis of Washington State is proposed. The Phase I area consists of the central portion of Puget Sound. Historically, material dredged from the sound's waterways was often used as fill for associated harbor and terminal development. Although this practice has continued, public concern about the filling of wetlands, tidal areas, and marshes has resulted in a curtailment of such activity. Since 1970, unconfined, open-water dumping has been the preferred means of disposal. The currently proposed plan would involve the use of three public multiuser unconfined, open-water disposal sites that would partially satisfy the future dredged material disposal needs of the Phase I area. Because the Phase I area contains the major urban and industrialized centers of development, where significant waste discharges have occurred, only approximately 60 percent of this area's future dredged material would be acceptable for unconfined, open-water disposal. An unconfined, open-water disposal site would be designated in each of the Tacoma, Seattle, and Everett urban embayments of Commencement Bay, Elliott Bay, and Port Gardner, respectively. The sites, while varying in size due to bathymetry, average approximately 350 acres in potential bottom impact area. Each site has a 900-foot radius, 58-acre surface disposal zone within which all suitable dredged materials would be released. The preferred sites would be located in areas relatively free of important biological resources and human use activities. The center of the Commencement Bay disposal zone would lie approximately one mile west of Browns Point in water approximately 530 feet deep. In Elliott Bay, the center of the disposal zone would lie approximately 0.75 mile north of Harbor Island in water approximately 265 feet deep. The center of the Port Gardner zone would lie approximately 2.25 miles southeast of Gedney Island in water approximately 420 feet deep. Site management plans and material evaluation procedures, related to the potential for long-term chemical effects that could be allowed on biological resources due to disposal, would be implemented. During the year 1985 to 2000 period, the Commencement Bay, Elliott Bay, and Port Gardner disposal facilities would receive 1.3 to 3.8 million cubic yards (MCYs), 3.1 to 6.2 MCYs, and 2.2 to 4.9 MCYs, respectively. Material designated for confined disposal during the same period would amount to 4,516 MCYs to 12,724 MCYs. Depending on the amounts of material designated for confined and unconfined disposal, the estimated costs of testing, dredging and disposal, and monitoring range from $150.1 million to $267.7 million. POSITIVE IMPACTS: Provision of a permanent disposal program for materials dredged from the Puget Sound waterways would support commerce on the waterways, which provide access to the Port of Seattle and Port of Tacoma. The ports' activities support 70,000 jobs and generate an annual business volume of nearly $4.0 billion. Site management plans and material evaluation procedures would prevent the release of toxic materials into the sound. NEGATIVE IMPACTS: Localized reductions in air quality could occur in the vicinity of the preferred open-water disposal sites due to exhaust emissions from disposal equipment. Temporary reductions in water quality at the sites would result from the release of sediments into the water column. Benthic habitat at the disposal sites would be smothered periodically. Use of the disposal sites would result in periodic disruption of navigation.

Preparation date: July 5, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RECOMMENDED PLANS FOR FLOOD CONTROL, COYOTE AND BERRYESSA CREEKS, SANTA CLARA COUNTY, CALIFORNIA. AN - 36381953; 1924 AB - PURPOSE: Plans for flood control on Coyote and Berryessa creeks in Santa Clara County, California are proposed. The lower Coyote Creek study area is located in the cities of San Jose and Milpitas in Santa Clara County, south of San Francisco Bay. Of the 12 preliminary structural and nonstructural plans considered, the Alternate Sides Overflow Channel and Offset Levees Plan for Coyote Creek is the preferred alternative. The plan would feature an overflow channel and offset levees set approximately 400 to 900 feet apart. The levees would vary between 4 and 9 feet in height, with a top width of 18 feet, and a side slope of 3 feet horizontal to 1 foot vertical (3H to 1V) on the inboard side and 2H to 1V on the outboard side. The width of the overflow channel would vary with geological and hydrological conditions. The plan would include hiking and bicycling trails and other recreational amenities to provide aesthetic quality and other recreational values on the east levee along Coyote Creek. It would mitigate for adverse environmental impacts, including fish and wildlife impacts, as well as other social effects. The plan has a benefit/cost ratio of 1.6; the first cost is presently estimated at $29.9 million. The Berryessa Creek study area is located in the cities of San Jose and Milpitas, California. The Trapezoidal Concrete Channel and Levee Plan has been tentatively selected as the recommended plan. Starting at the upstream project limit, approximately 600 feet upstream of Old Piedmont Road, the plan would feature a 500-foot by 160-foot (outside measurements) reinforced concrete-walled sedimentation basin with earth bottom that would undergo transition to a box culvert under Old Piedmont Road. A trapezoidal reinforced concrete-lined channel would lead out of the culvert and continue for almost 800 feet to the existing 400-foot-long box culvert under the intersection of Piedmont Road and Cropley Avenue. The bottom width would be eight feet, with side slopes of 1V to 2H. The trapezoidal channel would be constructed with a single service road on the east side of the creek to save the riparian vegetation that grows above the west bank. The plan would fully mitigate for adverse impacts to fish and wildlife and for other social effects; it has a benefit/cost ratio of 1.4 and a first cost presently estimated at $9.2 million. POSITIVE IMPACTS: The major beneficial impacts of the Coyote Creek plan include a reduction in future flood damages to existing public and private property and to business activities, the enhancement of future land use, the incorporation of hiking and bicycling trails and related amenities, and a gain in floodway habitat considered to be more valuable to wildlife than the existing upland or agricultural land within the setback levee system. The major beneficial effects of the Berryessa Creek plan include a reduction in future flood damages to existing public and private property and to business activities and the enhancement of the Berryessa Creek Park and greenbelt. NEGATIVE IMPACTS: The major adverse effects of the Coyote Creek plan, for which mitigation measure are intended to compensate, are that it would cause the loss of 13.6 acres of riparian habitat along Coyote Creek, with the associated adverse impacts to fish and wildlife, degradation of aesthetic quality, the relocation of the Camp Coyote facilities at Agnews State Hospital, and the removal of three historic buildings. The major adverse impact of the Berryessa Creek plan is the removal of riparian vegetation, for which mitigation measures are intended to compensate.

AN - 36381920; 1923 AB - PURPOSE: Flood control measures combining a flood levee and relocation plans are proposed for Clifton, Greenlee County, Arizona. Clifton is the county seat of Greenlee County, which is located in southeastern Arizona and borders Graham County, Arizona to the west and Grant and Catron counties, New Mexico to the east. The study area encompasses the San Francisco River floodplain within the urbanized areas of Clifton. The plan would include relocation of the Riverside Addition, East Clifton, North Clifton, and the Patterson Addition areas of Clifton. Approximately 108 residents would be relocated. A new subdivision would be constructed on Tabletop Mesa, some three miles south of the existing downtown area. The town of Clifton has purchased 120 acres of land from the Bureau of Land Management to allow for development of the site atop Tabletop Mesa. The evacuated portion of the floodplain would be redeveloped for recreational uses. The structural portion of the plan would consist of a 125-year levee for south Clifton, structural modification of a railroad bridge, and installation of flood control flap gates. The levee, which would be set back approximately 100 feet from the channel, would be 3,000 feet long and would have an average height of 8.5 feet. Final levee alignment would be determined during detailed design studies. In addition, the plan would include floodproofing of significant historic structures and businesses. The estimated cost of the plan is $11.6 million, of which the federal and nonfederal shares would be $8.5 million and $3.1 million, respectively. The benefit-cost ratio for the project is 1.4. POSITIVE IMPACTS: Levee construction would protect 212 homes and businesses in South Clifton. The full plan would provide developed urban residential areas of Clifton with complete protection against the 125-year-frequency flood and would greatly reduce flood damages to commercial establishments. Removal of septic systems, along with houses, from the floodplain would result in some increase in groundwater and river water quality. Housing relocations would also create additional open space and recreational areas in the vicinity of the river. NEGATIVE IMPACTS: Of the structures to be relocated from the floodplain, 39 appear eligible, or may be eligible, for inclusion on the National Register of Historic Places. Levee construction could impact two historic structures that also appear to be eligible for inclusion on the register. Mine tailings in the area of excavation could contain toxic materials, requiring use of special disposal methods. The levee would displace five acres of land.

Examples from artificial radionuclide studies in freshwater (Experimental Lakes Area in Northern Ontario, ELA) and coastal marine ecosystem enclosures (MERL tanks at Narragansett Bay, Rhode Island) show the cycling of selected trace elements across the sediment-water interface as these are influenced by various biogeochemical factors. The approach to meaningful studies using radiotracers should include the separate characterization of the physical transport processes, and preferably a comparison of the fate of radiotracers to those of stable elements in the same system, to allow for kinetic studies of chemical forms. The kinetics of transformation of different chemical species of Co, Hg, Ag, Se, and Cr ions, under variable pH (ELA) or redox (MERL) conditions appeared to be indirectly linked to the kinetics of organic carbon cycling. A better knowledge of the predominant chemical species of trace elements present in these systems will be important in understanding bioavailability, biomagnification, and toxicity of trace elements in aquatic ecosystems.

AN - 36404010; 1931 AB - PURPOSE: Implementation of a protective beach nourishment project along the 11.8 miles of shoreline between Sea Bright and Ocean Township in Monmouth County, New Jersey is proposed. The preferred alternative (beach restoration) consists of the construction of a sand berm and a sloping beach along the entire length of the project. The project would also include a component to ensure periodic renourishment of the beach and the notching of 15 existing groins. The design beach, which has a 100-foot-wide berm at an elevation of 10 feet above mean low water (MLW) and a berm cap extending to an elevation of 12 feet above MLW, would provide protection to upland property from erosion that would accompany a storm with a recurrence interval of 120 years. Material for construction and periodic nourishment of the beach would be obtained from borrow areas offshore of Sandy Hook and Belmar, New Jersey. Approximately 17.9 million cubic yards of material would be required for creation of the initial beach. Each periodic renourishment, which would occur at six-year intervals, would require placement of 3.5 million cubic yards. The initial cost of the recommended plan is $192.9 million, and the benefit-cost ratio is estimated at 1.71; the annualized cost of the project is estimated at $21.5 million. POSITIVE IMPACTS: Flood damage reduction, erosion control, reduced maintenance at Sandy Hook Park, recreational advantages, and intensification of development resulting from the project would result in annual economic benefits valued at $16.7 million, $2.1 million, $1.7 million, $7.8 million, and $8.3 million, respectively. Terrestrial species suited to beach habitat would benefit from enlargement of their habitat along the shoreline. NEGATIVE IMPACTS: Dredging from borrow areas and deposition of dredged material at the beach sites would result in temporary turbidity in the water column and would smother benthos. Bottom sediment and benthic communities in the borrow areas could change significantly, and the borrow areas could suffer from oxygen depletion. Nearshore areas currently characterized as tidal would be buried and transformed into beach.

Preparation date: June 30, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PLACER MINING ON THE MINTO FLATS WATERSHED, ALASKA. AN - 36396916; 1884 AB - PURPOSE: Continued management of placer mining claims on federal lands within the 2.2-million-acre Minto Flats watershed in Alaska is proposed. The Minto Flats drainage consists of the rivers and creeks that flow out of the Tanana Hills and into the marshy lowlands west of Fairbanks. The major streams of Minto Flats are the Chatanika and Tolovana rivers and Goldstream Creek. On May 14, 1987, the United States District Court for the District of Alaska instructed the Bureau of Land Management (BLM) to cease approving plans of operations for federal placer mines after October 1, 1987 in the Birch Creek watershed, pending completion of an adequate assessment of the cumulative effects of mining via an environmental impact statement. Additional injunctions followed, covering the watersheds of Beaver Creek, the Fortymile River, and Minto Flats. On July 22, 1987, the Court issued an amendment to the May 14 and May 28 orders, extending the date of cessation to November 15, 1987. Mining activities, under the preferred management plan, would be similar to those that occurred during the 1987 mining season. BLM would manage placer mining in the Minto Flats drainage according to Alaska state water quality standards, with federal variances. Reclamation activities would be required to reshape tailings to approximate the surrounding physiography and spread the overburden and available topsoil over the reshaped tailings. Settling ponds would be similarly reclaimed. The stream bypass would be stabilized or reinforced to make it the permanent channel. The reclaimed site would be allowed to revegetate naturally. Water quality performance standards would be 0.2 milliliters per liter of settleable solids and 5 Nephelometric Turbidity Units (NTU) above natural conditions when natural turbidity is 50 NTU or less, with not more than a 10 percent increase in the turbidity when the natural turbidity is 50 NTU, not to exceed a maximum increase of 25 NTU at the mine effluent discharge point. Under the proposed alternative, a total of 37 mines (12 federal and 25 state and private) would be operating continuously over the next 10 years in the watershed. Annual costs for all federal mining operations are estimated at $62,400 for water treatment and $24,000 for reclamation. POSITIVE IMPACTS: Minerals made available due to mining activities would include tin, tungsten, gold, tantalum, silver, uranium, and rare-earth elements. Motorized recreational access would be enhanced due to construction of roads associated with mining. It is likely that mining employment, total employment, mining income, and total income in the area would increase significantly over the next 10 years. NEGATIVE IMPACTS: Approximately 136 acres would regrow as riparian tall shrub within 30 years of reclamation, and an additional 64 acres would regrow within 50 years on mining disturbance in creek bottoms. Approximately 651 acres of mined land would remain barren or sparsely vegetated; approximately 5,240 acres of wildlife habitat would be physically altered due to mining in the watershed. Periodic disturbance to wildlife due to human activities and operation of vehicles and machinery would affect as much as 56,670 acres. Approximately 761 acres of upland riparian habitat would be lost for 30 to 50 years in the upper Chatanika, upper Goldstream /Cleary Summit, and upper Tolovana/Livengood areas. A minimal reduction in the moose herd would result. Physical alteration of streams and increases in suspended sediment from mining in the basin would result in unknown cumulative effects on the aquatic resources of the area. Ongoing sediment redeposition could affect subsistence activities downstream of mining areas.

AN - 36390111; 1928 AB - PURPOSE: Alternatives to the operation and regulation of Lake Red Rock in Marion County, Iowa, are being considered. The current operation plan requires that the lake be raised at intervals to compensate for sedimentation and to maintain the 50,000 acre-feet of water originally approved for the reservoir. Other alternatives would provide for raising the lake to predetermined levels at predetermined intervals. Alternatives that have been considered involve revised release rates and include: maintaining present operations; a dry pool; a one-step raise from 728 to 742 feet National Geodetic Vertical Datum (NGVD); a two-step raise from 728 to 736 to 742 feet NGVD; a three-step raise from 728 to 732 to 736 to 742 feet NGVD; and dredging of accumulated sediments. The recommended plan involves a one-step raise to elevation 734 feet NGVD. The conservation pool would be raised two feet in the fall for the benefit of migrating waterfowl in coordination with the Iowa Department of Natural Resources. Since filing of the final environmental impact statement in August 1976, no substantial changes have taken place in planned activities. Periodic structure repair and landscaping and maintenance of launching ramps, swimming beaches, signs, and trails have been required on a more frequent basis than originally anticipated, due to damage from near-record precipitation and flood events in the Des Moines River Basin. First costs are estimated at $1.9 million, with a benefit-to-cost ratio of 2.0. POSITIVE IMPACTS: The recreation experience at the lake would be enhanced by improving aesthetics, boating, fishing, and wildlife habitat, and part of the recreational needs of south-central Iowa would be fulfilled. Residential property values could increase slightly. The increased potential for recreation visitors to the lake could attract new businesses to the area and create new employment opportunities. NEGATIVE IMPACTS: Construction machinery would generate a temporary increase in noise during scheduled relocation of facilities, creating a minor, short-term disturbance to recreationists at the lake. Recreation at various facilities would be temporarily disrupted during the construction phase. The values of farm properties could be adversely impacted. An increased risk of flooding, resulting from any raise in pool elevation, is perceived by area farmers. LEGAL MANDATES: Water Resources Development Act of 1976 (42 U.S.C. 1962d et seq.).

AN - 36406171; 1875 AB - PURPOSE: Construction of a Trans-Alaska Gas System (TAGS) as a 796.5-mile buried, chilled, high-pressure, 36-inch-diameter natural gas pipeline between Prudhoe Bay and a tidewater terminal and liquefied natural gas (LNG) plant at Anderson Bay, Alaska is proposed. TAGS would parallel the existing Trans-Alaska oil pipeline system in its entirety and a portion of the authorized but as yet unconstructed Alaska Natural Gas Transportation System. TAGS would include 10 compressor stations constructed at regular intervals along the pipeline to provide pressures ranging from 1,100 to 2,220 pounds per square inch, an LNG plant that would include four LNG processing units to liquefy gas at minus 259 degrees Fahrenheit, four LNG tanks, and marine terminal facilities. The operations and control center for the TAGS projects would be located in Valdez, headquarters and administration offices would be located in Anchorage, and maintenance facilities in Fairbanks. TAGS would have a throughput of 2.3 billion cubic feet of conditioned natural gas. Gas pumped and processed by TAGS would be liquefied and exported by tanker to Japan, Taiwan, and Korea. POSITIVE IMPACTS: Exports of LNG allowed by the TAGS system at full operating potential would reduce the U.S. balance of trade deficit by $2.5 billion annually. Construction and maintenance of TAGS would provide substantial support to the area employment base. NEGATIVE IMPACTS: An employment boom during construction of TAGS would result in high levels of unemployment following the completion of the project, placing some burden on state and local social services. Approximately 23,000 acres of vegetated land would be cleared during construction, and moderate but long-term land use impacts would affect approximately 8,000 acres within the pipeline rights-of-way and areas occupied by related facilities. Operation of the terminal, compressor stations, and LNG plant would cause ongoing disruptions to ambient environments. Some surface and groundwater would be consumed during construction, and streams would be affected by turbidity. The marine terminal would displace 100 acres of benthic habitat, and an undetermined loss of seabird and waterfowl habitat would occur at Anderson Bay. Disturbance of 3,200 acres of wetlands would occur, and Dall sheep winter range would be disturbed. Riparian moose habitat and swan and loon habitat would be displaced, and large game mortalities would occur in the Delta Junction area. Disturbance of endangered Arctic peregrine falcons and their prey could result from construction activities. Wilderness and other recreational values would be reduced in the area, and subsistence resources would be disturbed during construction.

Preparation date: June 27, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DISPOSAL OF DREDGED MATERIAL FROM THE PORT OF NEW YORK AND NEW JERSEY (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1983). AN - 36404014; 1853 AB - PURPOSE: Use of subaqueous borrow pits for disposal of material dredged from the Port of New York and New Jersey is evaluated. This draft document supplements the final environmental impact statement (FEIS) of March 1983 on designation of the Mud Dump Site in the New York Bight as the chief receiver of material dredged from the port. Major findings of the FEIS are reviewed, with specific attention to alternatives identified as feasible for handling potentially contaminated dredged material. The FEIS conclusion indicating the use of subaqueous borrow pits for the disposal of material designated as unsuitable for unrestricted ocean disposal constitutes the main focus of the supplemental statement. The supplement incorporates results of recent physical and biological studies designed to update the alternatives that the FEIS considered for disposal of large volumes (350,000 cubic yards per year) of potentially contaminated sediments. In addition to subaqueous borrow pits, this supplement concludes that shallow ocean disposal with capping, containment facilities, and upland disposal would constitute feasible alternatives for the disposal of contaminated dredged materials. Subaqueous borrow pits would continue to be forwarded as the environmentally preferred alternative. Other alternatives considered in the supplemental statement include use of an existing pit site or excavation of a new pit site. After comparing the use of new and existing pits, the supplement concludes that digging new pits for use might represent a delay in implementation of several years. Consequently, if pit disposal were chosen, disposal would involve use of an existing pit for immediate containment of potentially contaminated dredge material and construction of a new pit for future use. Finally, the supplement considers a number of operational and management procedures for site use. POSITIVE IMPACTS: Use of subaqueous borrow pits would ensure the project's long-term ability to isolate contaminants from the water column, minimal impacts to aquatic resources and human health, and immediate availability of such sites and the high probability of success. Designation of disposal sites would allow for continued maintenance and improvement of waterways within the Port of New York and New Jersey, the nation's leading seaport and a major contributor to the national and regional economy. NEGATIVE IMPACTS: Disposal of dredged material at the shallow water site would result in burial of benthos, destruction of benthic habitat, alteration of the sediment structure, short-term degradation of the local water quality due to turbidity, and possible long-term contamination of site sediment.

Preparation date: June 24, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ISSUANCE OF A NEW SOURCE NATIONAL POLLUTION DISCHARGE ELIMINATION SYSTEM PERMIT TO CF MINING CORPORATION, HARDEE PHOSPHATE COMPLEX II, HARDEE COUNTY, FLORIDA. AN - 36402412; 1812 AB - PURPOSE: Issuance of a new source national pollutant discharge elimination system permit for development and operation of an open-pit phosphate mine and beneficiation plant on a 14,994-acre site in Hardee County, Florida is proposed. Mining activities would encompass 14,647 acres, all of which would have to be reclaimed and would produce 94 million tons of phosphate products over a 27-year period. The mine operation would produce approximately 2.0 million tons per year of wet phosphate rock for the first seven years of mining and 4.0 million tons per year during the following 20 years. During mining, all of the rock mined from the project would be shipped to fertilizer plants for conversion to finished fertilizer, with 100 percent of the tonnage going to existing fertilizer manufacturing facilities at Plant City and Bartow. To accomplish these operational objectives, a beneficiation plant and temporary rock storage facility would also be constructed on the site. The initial phase of the action would involve land clearing and open burning of cleared debris. The cleared acreage in front of the mining operation would average approximately 80 acres. The mining operation would utilize a single 55-cubic-yard dragline, beginning in the eighth year of mining, supplemented with a second similar dragline. The mined matrix would be slurried and transported via pipeline to the beneficiation plant for washing. An access railroad spur would be constructed to link the plant with the Seaboard Systems Railroad that presently bisects the property. Waste disposal would be via sand/clay mining. Approximately 100 million gallons of water would be used per day to support mining and beneficiation; 93.5 million gallons per day would be supplied from a recirculation system and 7.85 million gallons per day would be removed from groundwater sources. The reclamation plan would be based on the use of waste sand and clay mix material as backfill over most of the mined area; the plan would return the mined land to uses compatible with surrounding area uses, which are primarily agricultural. POSITIVE IMPACTS: The new operation would allow the permit applicant to maintain a continuous supply of phosphate fertilizer for its cooperative member organization. The phosphate rock resulting from this initial expansion would be used to replace existing rock supply contracts. In addition to contributing to the nation's supply of fertilizer, the project would boost the local and regional economy. Reclamation activities would increase the acreage of improved pastureland, forested uplands, freshwater marsh, freshwater swamp, and lakes. NEGATIVE IMPACTS: Mining would reduce the acreage of palmetto prairie, field and row crops, and citrus orchards, even after reclamation. The geological and soil composition of the site would be altered significantly. LEGAL MANDATES: Federal Water Pollution Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: June 17, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOWER GRANITE PROJECT, SNAKE RIVER, WASHINGTON (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1975 ON INTERIM NAVIGATION AND FLOOD PROTECTION DREDGING). AN - 36397154; 1869 AB - PURPOSE: Implementation of a navigation and flood control project is proposed in the confluence area of the Snake and Clearwater rivers of Nez Perce County, Idaho and Asotin, Garfield, and Whitman counties, Washington. Accumulation of sediment in the confluence area has been occurring as a result of the completion of Lower Granite Dam in 1975. Sedimentation reduces the level of flood protection provided to the city of Lewiston, Idaho, and represents a potential threat to life and property. Sediment deposition also reduces water depths for navigation to the Ports of Whitman, Clarkston, and Lewiston. This statement, which supplements the final environmental impact statement (FEIS) of July 1975 on the dam project, evaluates an interim action to satisfy navigation and flood protection requirements within the Lower Granite Reservoir until a long-term solution can be selected and implemented. The supplement also discusses an in-water disposal test with monitoring in an adaptive process to obtain information in support of the evaluation of long-term in-water disposal. The project would involve annual dredging operations, commencing not earlier than December 15 and continuing until achievement of the sediment removal objective or March 21, whichever occurred sooner. Dredging would occur primarily in the Snake River at or near the confluence of the Clearwater River downstream of the Port of Whitman. Navigation dredging within the Clearwater River arm could include the access channel, berthing area, and turning basin for the Port of Lewiston. Approximately 400,000 cubic yards of sediment would be removed every three years to maintain navigation. Snake River flood protection dredging would require removal of at least 800,000 cubic yards of material and as much as 1.2 million cubic yards of sediment annually from selected river reaches. In-water disposal would occur in mid-depth (20 to 60 feet deep) and deep water (deeper than 60 feet) sites below Snake River Mile 120. An integral part of this proposal would be a test of in-water disposal of dredge material to determine the effects of such disposal on the aquatic habitat and fishery resources in the reservoir. The upland disposal option would involve disposal in containment ponds presently on the Wilma Habitat Management Unit. This site would be capable of containing one upland disposal episode; additional upland sites would have to be located if more than one upland disposal episode occurred during the interim project. POSITIVE IMPACTS: Dredging would provide flood protection for the levee system associated with the reservoir and clear navigation channels within the area. The in-water disposal monitoring program would assure that environmental damage due to disposal of dredged material would be minimized. NEGATIVE IMPACTS: Several physical-chemical effects related to dredging and disposal would occur in the rivers. Dredging and disposal operations would elevate turbidity and levels of suspended solids in the rivers. Contaminants would be released from sediment. Dissolved oxygen and temperature changes due to dredging and disposal would be slight. Benthic organisms would be destroyed. Use of the Wilma disposal site would destroy wildlife habitat and displace wildlife to habitat outside the affected area. A potential for conflict with a local sport fishery would exist at the mouth of the Clearwater River and in the reservoir near the in-water disposal activity.

AN - 36396867; 1838 AB - PURPOSE: Widening and new construction of Maryland (MD) Route 28 in Montgomery County, Maryland, beginning west of MD Route 124 and extending easterly to Interstate 270 (I-270), a distance of 5.6 miles, are proposed. The project would also include improvements to MD Route 124 from approximately 1,000 feet south of MD Route 28 to 4,000 feet north of MD Route 28, tying into the existing improved section constructed by Montgomery County. The project would involve widening and reconstruction of MD Route 28 to a curbed section minor arterial highway. The improvements would be constructed within a 120-foot right-of-way established by Montgomery County through development setbacks over the years. Beginning at approximately west of MD Route 124, the existing roadway would be widened to provide a six-lane roadway with a 20-foot median to provide storage for left-turning vehicles. The design speed of this urban highway would be 50 miles per hour. The second segment of the project would involve designation of Key West Avenue at MD Route 28 for through traffic, leaving existing MD Route 28 for local traffic. Relocated MD Route 28 via Key West Avenue would provide a six-lane partial controlled-access roadway with a 30-foot median contained within a 150-foot right-of-way. Two lanes of Key West Avenue have been constructed from the intersection of MD Route 28 to Shady Grove Road. Montgomery County is constructing Key West Avenue from Shady Grove Road to Gude Drive extended, along the Master Plan Alignment for MD Route 28. From Gude Drive, the proposed alignment continues in a southeasterly direction to tie into existing MD Route 28, 800 feet west of Research Boulevard. It would continue to the limit of the project at approximately station 434+00 to tie into the proposed improvements of the interchange at I-270 and MD Route 28. The estimated costs of rights-of-way acquisitions and construction are $3.2 million and $43.0 million, respectively. POSITIVE IMPACTS: The proposed improvement would relieve congestion on the existing facility and improve traffic operations throughout the study area, providing improved access to an area planned for residential, institutional, and high-tech development, based on established zoning. NEGATIVE IMPACTS: Rights-of-way development would result in displacement of two residential units housing minority persons, 0.4 acre of parkland, 3.4 acres of farmland, 3.3 acres of wetland, 2.2 acres of floodplain, 12.1 acres of woodland, and 1.7 acres of old field. One historic site would be affected. Noise levels would be excessive at four sites.

Preparation date: June 8, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PLACER MINING ON THE FORTYMILE RIVER WATERSHED, ALASKA. AN - 36399805; 1809 AB - PURPOSE: Continued management of placer mining claims on federal lands within the 3.1-million-acre Fortymile River watershed in the upper Yukon-Canada subregion of Alaska is proposed. The Fortymile River is formed at the junction of its North and South forks and flows northeast approximately 60 miles to its mouth at the Yukon River, approximately 30 miles southeast of Eagle, Alaska. The majority of lands within the Fortymile River watershed below the intersection of the North Fork and the Main Stem have been tentatively approved for conveyance to the state of Alaska. On May 14, 1987, the United States District Court for the District of Alaska instructed the Bureau of Land Management (BLM) to cease approving plans of operations for federal placer mines after October 1, 1987 in the Birch Creek watershed, pending completion of an adequate assessment of cumulative effects of mining via an Environmental Impact Statement. Additional injunctions followed, covering the watersheds of Beaver Creek, the Fortymile River, and Minto Flats. On July 22, 1987, the court issued an amendment to the May 14 and May 28 orders, extending the date of cessation to November 15, 1987. Mining activities, under the preferred management plan, would be similar to those that occurred during the 1987 mining season. BLM would manage placer mining according to Alaska state water quality standards, with federal variances. Reclamation activities would be required to reshape tailings to approximate the surrounding physiography and spread the overburden and available topsoil over the reshaped tailings. Settling ponds would be similarly reclaimed. The stream bypass would be stabilized or reinforced to make it the permanent channel. The reclaimed site would be allowed to revegetate naturally. Water quality performance standards would be 0.2 milliliters per liter of settleable solids and five Nephelometric Turbidity Units (NTU) above natural conditions when natural turbidity is 50 NTU or less and not more than a 10 percent increase in the turbidity when the natural turbidity is 50 NTU, not to exceed a maximum increase of 25 NTU at the mine effluent discharge point. Under the proposed alternative, a total of 37 mines (20 federal and 17 state and private) would be operating continuously over the next 10 years in the watershed; most of the mines would operate in the Mosquito-South Fork, Wade, and Canyon Creek drainages. POSITIVE IMPACTS: Minerals made available due to mining activities would include tin, tungsten, gold, tantalum, silver, uranium, and rare-earth elements. Motorized recreational access would be enhanced due to construction of roads associated with mining. It is likely that mining employment, total employment, mining income, and total income in the area would increase significantly over the next 10 years. NEGATIVE IMPACTS: Soil profiles would be completely altered and vegetation destroyed by mining operations on approximately 851 acres of land. Water quality would be affected by short- to long-term increases in suspended sediments and turbidity and accelerated local erosion, resulting in a possible increase in sedimentation introduced into the stream bypass in the vicinity of the disturbed area. The impact of sedimentation on water quality from nonpoint sources is uncertain. Approximately 155 acres would regrow as riparian tall shrub within 30 years of reclamation, and an additional 222 acres would regrow within 50 years on mining disturbance in creek bottoms. Approximately 632 acres of mined land would remain barren or sparsely vegetated. Some 3,209 acres of wildlife habitat would be physically altered due to mining in the watershed. Periodic disturbance to wildlife due to operation of vehicles and machinery and human activities would affect as much as 220,343 acres. Approximately 851 acres of upland riparian habitat would be lost in the Wade Creek and Walker Fork drainages, the vicinity of Chicken, and other areas for 30 to 50 years. A minimal reduction in the moose herd would result. Mining activities could affect three candidate threatened or endangered species and three endemic species. Physical alteration of streams and increases in suspended sediment from mining in the basin would result in unknown cumulative effects on the aquatic resources of the area.

Preparation date: June 3, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DESIGNATION OF A NEW OCEAN DREDGED MATERIAL DISPOSAL SITE, PENSACOLA, FLORIDA. AN - 36398010; 1859 AB - PURPOSE: Designation of an ocean-dredged material disposal site in the Gulf of Mexico south of Pensacola, Florida is proposed. The purpose of the action is to provide environmentally acceptable alternatives for disposal of dredged material from the Naval harbor facilities at Pensacola which, due to expansion of the harbor, would require disposal facilities for an additional 4.1 million cubic yards of fine-grained material during construction of a turning basin and expansion of the Pensacola Bay channel. The preferred disposal site is located within a site centered at approximately 30 degrees, 8 minutes north latitude (N) and 87 degrees, 18 minutes, 35 seconds west longitude (W). The site would be large and deep enough that material disposed therein would remain within designated site boundaries during normal circumstances. More specifically, the site would cover 17 square miles as defined by the following coordinates: 30 degrees, 9 minutes, 35 seconds N; 30 degrees, 6 minutes, 36 seconds N; 87 degrees, 21 minutes, 5 seconds W; 87 degrees, 15 minutes, 43 seconds W. The northern side of the site would lie approximately 11 miles south of Pensacola Pass. Depths at the site range from 60 to 95 feet, and the bottom is generally classified as hard, sand shell. Studies are currently underway, utilizing a numerical model that simulates transport of disposed material as it descends through the water column and spreads over the ocean bottom under varying hydrodynamic conditions, to determine the effects of disposal at the site. POSITIVE IMPACTS: Enlargement of the harbor allowed by designation of the ocean dumping site would provide for a better mix of ships at Pensacola. The Navy would be able to homeport the U.S.S. Kitty Hawk and a naval reserve patrol craft. The disposal needs resulting from dredging of a civil works navigation channel from the Gulf of Mexico to the port, as well as a number of channels maintained in the area by local entities and private citizens, would also be met by designation of the ocean dumping site. The designated ocean site would lie within an economically transportable distance yet would be sufficiently removed from amenities such as beaches, fish havens, reefs, and hard bottom areas so that these areas would not be damaged. NEGATIVE IMPACTS: Use of the proposed site would result in temporary degradation of water quality during dumping operations, alteration of site bathymetry and sediment composition, and smothering of benthic organisms. Water quality impacts would include increased turbidity, potential release of chemical constituents, and lowering of dissolved oxygen levels. Changes in site bathymetry could be minimized by controlling the discharge point. LEGAL MANDATES: Marine Protection, Research, and Sanctuaries Act of 1972 (16 U.S.C. 1431 et seq.).

Many of the reservoirs are multiple purpose, with flood control as a primary purpose. Day-to-day operational decisions are generally made in water control centers located in the Corps' district offices. Some of these offices utilize a water-control software system developed by the Hydrologic Engineering center, which facilitates the decision-making process with capabilities for processing meteorologic and hydrologic data, forecasting runoff and simulating reservoir system performance. A component of the software system is computer program HEC1F, which performs runoff forecasting. The focus of this paper is on application of HEC1F in making short-term (three to five day) forecasts for the 11,733 square mile (30,440 sq. km.) Allegheny River Basin, which contains nine flood control reservoirs operated by the Pittsburgh District, Corps of Engineers. Following a brief overview of the nature and scope of the water control software system, the intended application of HEC1F is provided. The characteristics of the Allegheny Basin, data collection networks, and forecast needs are described, as well as the approach used for model calibration and initial results. Finally, comments are made regarding the present status of model development and usage, and plans for the future. JF - Technical Papers.

AN - 36401450; 1868 AB - PURPOSE: Implementation of a flood control plan for the Chehalis River at South Aberdeen and Cosmopolis, Grays Harbor County, Washington is proposed. This supplement to the final environmental impact statement (FEIS) of January 1977 addresses changes in the initial design of the authorized flood control project and compares the initial design with the current project design, which is based on studies made since 1984. The supplement also provides additional design information requested by resource agencies commenting on the 1977 FEIS. The initial design of the project would have involved construction of a 24,700-foot-long levee system. Of this length, 22,500 feet would have been earth embankment levee and 2,200 feet would have been concrete floodwall. Riprap would have been placed on levee side slopes along 5,900 feet of the levee. Pumping stations and gated drainage culverts were to be constructed at Devonshire, Shannon, and Miller sloughs and Alder and Mill creeks. Riprap would also have been required on some 8,480 feet of drainage channel banks upstream and downstream of the drainage structure. Areas adjacent to the levee were to be overbuilt to provide landscaping opportunities. As currently proposed, the project would include 11,550 feet of earth embankment levee, 6,010 feet of high ground, and 4,740 feet of sheetpile floodwall. Approximately 470 lineal feet of riprap would be required at the drainage structures. No pumping stations would be installed. A combination of flap and sluice gates would be used on drainage culverts to provide improved fish passage on Miller, Shannon, and Devonshire sloughs and Alder Creek, all of which currently have flap gates. A new sluice gate would be installed at Mill Creek, which is presently ungated. Landscaping measures would be implemented to restore 2.2 acres of estuarine wetlands and 0.6 acres of shrub/forest wetland to mitigate for project damages to wetlands. Estimated project construction costs amount to $9.9 million at 1987 price levels, while annual operation and maintenance costs are estimated at $35,000 over the 100-year project life. POSITIVE IMPACTS: Compared to the initial design, the current design would impact 13 fewer acres of habitat and 7.7 fewer acres of wetlands. Existing and future residential development and commercial properties would be protected from flooding. Average annual inundation reduction benefits under future growth conditions would amount to more than $1.5 million, reflecting an approximate reduction of 99 percent in the current level of average annual flood damages of $1.6 million. Expenditure of project funds would stimulate the economy of the Hoquiam-Aberdeen-Cosmopolis area of Grays Harbor County. NEGATIVE IMPACTS: Construction activities would destroy 7.9 acres of habitat, of which 4.3 acres would be wetlands (0.9 acres of estuary and 3.4 acres of shrub/forest). Three roads, three houses, and one shed would require relocation, as would numerous utility lines. Rights-of-way requirements would total 49.82 acres, of which 2.16 acres would be used only during construction. Affected acreage would include 39.52 acres within the city of Aberdeen, 7.5 acres in Cosmopolis, and 2.8 acres in Grays Harbor County.

Preparation date: May 27, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DES MOINES RECREATIONAL RIVER AND GREENBELT, DES MOINES RIVER, IOWA. AN - 36396660; 1829 AB - PURPOSE: Development, operation, and maintenance of a recreation and greenbelt area on and along the Des Moines River in Des Moines, Iowa, between the point at which the river is intersected by U.S. Highway 20 at Fort Dodge to the point downstream at which relocated State Highway 92 intersects the Des Moines River below the Red Rock Dam, are proposed. The project would include, but not be limited to: (1) the construction, operation, and maintenance of recreational facilities and streambank stabilization structures; (2) the operation and maintenance of this project (other than any such structure operated and maintained by any person under a permit or agreement with the Secretary of the Army) within the area; (3) such tree plantings, trails, vegetation, and wildlife protection and development and other activities as would enhance the natural environment for recreational purposes; and (4) the prohibition or limitation of the killing, wounding, or capturing at any time of any wild bird or animal. Nineteen of the originally proposed 121 projects were eliminated from further study. Of the remaining 102 projects, 4 involve development of trails or scenic routes, 21 propose land acquisition and/or environmental enhancement measures, 7 involve streambank stabilization, and 70 involve development or improvement of various aquatic or terrestrial recreation facilities. Site plans, preliminary cost estimates, and general evaluation of potential environmental and social impacts have been developed for each of these projects. The General Design Memorandum (GDM) does not contain site plans developed in sufficient detail to permit a detailed analysis of environmental, social, or economic impacts. Prior to construction of any greenbelt projects, a site-specific environmental assessment would be prepared for public and agency review. Formulation of site and design alternatives for projects involving development or modification of terrestrial and aquatic areas would attempt to maximize this potential while minimizing the potential for adverse effects from construction, operation, and maintenance of facilities. POSITIVE IMPACTS: Several of the identified projects located in the city of Des Moines could result in a noticeable improvement in scenic or other aesthetic values within the downtown area and in parts of recreation areas. Recreation projects located in or near urban areas could have some minor effect on actual or potential community growth. Several of the identified projects could indirectly increase property values in surrounding areas by providing recreational opportunities that could add to the economic potential of the area or enhance its attractiveness to prospective buyers. Completed recreation projects would enhance local, and in some cases regional, recreational opportunities while alleviating some of the demands on existing facilities. Construction could cause a short-term increase in employment and business activity. Several projects would be beneficial for protection, interpretation, or enhancement of historic properties. Projects that increase vegetative cover or stabilize streambanks could result in some improvement in water quality by reducing soil erosion. NEGATIVE IMPACTS: Some acquisition of farmland may be required for environmental enhancement projects or as rights-of-way for trails and other recreation projects. Several projects could result in the loss of bottomland forest habitat or alter the existing water quality and habitat value of portions of the Des Moines River. Several construction projects would result in adverse effects to significant historic properties. Loss of tax revenues could result from implementation of projects involving public acquisition of private lands.

Preparation date: May 25, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OX MOUNTAIN SANITARY LANDFILL, APANOLIO CANYON EXPANSION SITE, SAN MATEO COUNTY, CALIFORNIA. AN - 36389280; 1852 AB - PURPOSE: Expansion of the existing Ox Mountain Sanitary Landfill in San Mateo County, California is proposed. The facility is a Class III (nonhazardous waste) facility. In 1965, the county began plans for development of the Corinda Los Trancos Canyon phase of the Ox Mountain Sanitary Landfill; that phase became operational in 1976 and the Corinda Los Trancos Canyon facility of the Ox Mountain Landfill subsequently became the major recipient of county-generated solid waste. At that time, expansion into the adjacent Apanolio Canyon on completion of fill in the Corinda Los Trancos Canyon site was anticipated, and planning for the expansion was initiated. Applications for a use permit were submitted in 1982 and 1984. At its current size, the Ox Mountain facility would reach design capacity in 1989. Under the preferred alternative, the facility would be expanded by constructing a large-capacity landfill in Apanolio Canyon, which lies approximately three miles northeast of the city of Half Moon Bay and is just west of the existing Corinda Los Trancos Canyon Landfill. Apanolio Canyon is steep-walled, with side slopes ranging from 20 to 200 percent and elevations ranging from 500 to 1,500 feet within the proposed landfill expansion area. The landfill would occupy the northern portion of the canyon from an elevation of approximately 500 feet to an ultimate perimeter elevation of 1,200 feet. The 285-acre site would have a refuse capacity of 123.7 million cubic yards and would have an estimated lifespan of approximately 93 years. Site access would be via Highway 92 and an existing two-lane paved access road through the existing Corinda Los Trancos Canyon Landfill. The access road would be extended from the existing landfill into Apanolio Canyon. Landfill construction would involve a cut/fill operation, similar to that used at the Corinda Los Trancos Canyon site. Fill would begin at the lowest portion of the landfill and progress from the back of the canyon forward and then upward. The working face of the landfill would be limited to a small area and would have a three-on-one (horizontal to vertical) final slope. Daily and interim cover would require an estimated 200,000 cubic yards of material per year, which would be taken from on-site sources. The cost of construction of the landfill is estimated at $129.4 million, resulting in a cost of $1.05 per cubic yard of compacted refuse dumped within the landfill. POSITIVE IMPACTS: Landfill expansion would provide space for disposal of solid waste within the county, where the number of disposal sites has steadily decreased over the past 25 years as old, relatively small facilities have reached their capacities. Increasing the capacity of the Ox Mountain Landfill would provide for an additional solid waste disposal area at the only appropriate facility that receives waste materials collected by scavenger companies and that currently handles 91 percent of the solid waste generated by the county. NEGATIVE IMPACTS: Project activities would fill the northern portion of Apanolio Canyon, modifying the topography of the site. Site preparation and landfill operations would increase the potential for erosion and sedimentation in Apanolio Creek downstream of the project area. Clearing and excavation operations along the canyon walls during site preparation would increase the potential for landslides. The site would lie within an area that has been affected by seismic activity, lying approximately three miles west of the San Andreas fault zone. Ground shaking could cause landslides along the canyon walls and structural damage to the landfill underdrain, liner, or leachate collection systems; such damage could result in movement of leachate into ground- and/or surface-water systems. Landfill construction would ultimately fill approximately 20 percent of the canyon watershed and eliminate 285 acres of vegetation and wildlife habitat. Approximately 3.4 acres of wetlands would be filled or disturbed. Drainage control on approximately 5,600 feet of Apanolio Creek would eliminate 3,676 feet of resident rainbow trout and potential steelhead trout habitat. The landfill could attract rodents, insects, and other vectors capable of transporting disease and would permanently degrade the visual quality of the canyon.

Preparation date: May 24, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HYDROELECTRIC DEVELOPMENT IN THE UPPER OHIO RIVER BASIN, OHIO, PENNSYLVANIA, AND WEST VIRGINIA (FERC DOCKET NO. EL85-19-114). AN - 36405831; 1806 AB - PURPOSE: Twenty-four hydroelectric projects, capable of producing a total of 1,912 gigawatt-hours of electric power per year and scheduled for construction in Ohio, Pennsylvania, and West Virginia, are under consideration. The projects would be sited at 19 existing dams in the Ohio River basin; 18 of the sites are at navigation lock-and-dam (L&D) complexes. Rivers on which the projects would be sited include the Allegheny, Tygart, Monongahela, Muskingum, and Ohio. More specifically, the candidate projects would be situated at Allegheny River L&D Nos. 2, 3, 4, and 7; the Tygart Dam; Opekiska L� Hildebrand L� Point Marion L� Maxwell L� Monongahela L&D No. 4; Emsworth L� Sahields L� Montgomery; New Cumberland L� Pike Island; Willow Island L� Belleville; Gallipolis L� and Muskingum River L&D No. 3. The alternative possibilities include four different means of developing hydroelectric power in the upper basin. The preferred plan would involve implementation of projects at 15 of the 19 sites, allowing for generation of 78 percent of the power proposed by the project applicants. POSITIVE IMPACTS: Projects allowed under the proposed action would produce 1,494 gigawatt-hours of energy per year for the three-state region. The alternative allows for generation of this additional energy, while preventing projects from causing dissolved oxygen concentrations in receiving waters that would be low enough to affect aquatic life. Significant impacts to wetlands, fisheries, and recreational use of the river basin would be avoided. NEGATIVE IMPACTS: Hydropower generation at the proposed project sites would result in some loss of dissolved oxygen in the receiving waters. Generation would reduce the amount of volatile pollutants that are assumed to leave the water at dams. Sediments would be disturbed by project construction and operation. Fish would be entrained in turbines, and some mortality would result from direct or latent injuries, primarily affecting immature gizzard shad and freshwater drum but also affecting game fish on occasion. Tailwater habitats would undergo changes, altering habitat for aquatic life requiring high water velocities. During certain site-specific ranges of flows, the largest percentage of river flow would be through turbines at one end of the dams rather than through gates or over fixed crests across the width of the dam. Water velocities would be decreased in much of the present tailwater seasonally. Head reduction at fixed-crest dams would cause an increase in water velocity in the upstream pool and dewatering of shoreline fish habitat. Dredging for the powerhouses and turbine intake and discharge areas would cause an unavoidable loss of a small amount of river bottom habitat. Riparian and wetland vegetation would be destroyed due to construction activities and displaced by project facilities. Hydroprojects at fixed-crest dams would cause drops in the pool elevation that could only be mitigated by the addition of flashboards, which may not be permitted by regulatory authorities. Recreational fishing activities would be disrupted during a construction period that would span three years.

AN - 36402853; 1798 AB - PURPOSE: Establishment of an acoustic measurement facility at Behm Canal in the Ketchikan Gateway Borough of southeastern Alaska is proposed to measure and define the acoustic signature of quiet operating submarines and to predict their vulnerability to detection. The facility would consist of an underway measurement site, located in the central portion of the canal; a static measurement site, located northwest of Back Island; and shore facilities, located on Back Island. The 500-yard-wide, 10,000-yard-long underway measurement site would be equipped with tracking arrays that would monitor submarines acoustically as they pass through the site and transmit sounds to the shore facilities. The static measurement site would consist of bottom-moored acoustic measurement arrays similar to those at the underway measurement site. The shore facilities would include an operations area on the northwestern side of the island and a dock area on the western side. A danger area and restricted zones would be established in association with the facility. Construction of the facility would begin in 1989, and operations would be initiated early in 1991. POSITIVE IMPACTS: By providing a facility to measure and qualify the acoustic signature of U.S. Navy submarines, the project would contribute to the maintenance of the nation's defense system. The facility would replace facilities at Carr Inlet, Washington and Santa Cruz Island, California, where man-made noise interferes with operations. NEGATIVE IMPACTS: Shore facilities at Back Island would displace approximately 12 acres of faunal habitat. Site activities would place some pressure on area fauna, and aesthetic values of the island would be depleted slightly. Benthic fauna in the vicinity of the pier would be displaced.

Preparation date: May 13, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PLACER MINING ON THE BIRCH CREEK WATERSHED, ALASKA. AN - 36402374; 1808 AB - PURPOSE: Continued management of placer mining claims on federal lands in the 1.4-million-acre Birch Creek watershed, located approximately 70 miles northeast of Fairbanks, Alaska, under conditions provided for during the summer of 1987 is proposed. The majority of the watershed lies within the Steese National Conservation Area of the Yukon-Tanana Upland physiographic province, an area of Interior Alaska that consists of rounded hills around a high central area of rugged mountains. The province is bounded on the north by the Yukon River and on the south by the Tanana River. Birch Creek is formed at the confluence of Bates and Ptarmigan creeks near Porcupine and Mastodon domes. Other major tributaries include Crooked, Porcupine, Deadwood, and Harrison creeks and Harrison Fork. Birch Creek runs approximately 344 miles from its headwaters to its mouth at the Yukon River west of Fort Yukon. On May 14, 1987, the U.S District Court for the District of Alaska instructed the Bureau of Land Management (BLM) to cease approving plans of operations for federal placer mines after October 1, 1987 in the Birch Creek watershed, pending completion of an adequate assessment of the cumulative effects of mining via an Environmental Impact Statement. Mining activities, under the preferred management plan, would be similar to those that occurred during the 1987 mining season. BLM would manage placer mining in the Birch Creek drainage according to Alaska state water quality standards, with federal variances. Reclamation activities would be required to reshape tailings to approximate the surrounding physiography and spread the overburden and available topsoil over the reshaped tailings. Settling ponds would be similarly reclaimed. The stream bypass would be stabilized or reinforced to make it the permanent channel. The reclaimed site would be allowed to revegetate naturally. Water quality performance standards would be 0.2 milliliters per liter of settleable solids and five Nephelometric Turbidity Units (NTU) above natural conditions when natural turbidity is 50 NTU or less, and not more than a 10 percent increase in the turbidity when the natural turbidity is 50 NTU, not to exceed a maximum increase of 25 NTU at the mine effluent discharge point. As many as 80 mines (48 federal and 32 state and private) would operate continuously over the next 10 years. POSITIVE IMPACTS: Minerals made available due to mining activities would include tin, tungsten, gold, tantalum, silver, uranium, and rare-earth elements. Motorized recreational access would be enhanced due to construction of roads associated with mining. It is likely that mining employment, total employment, mining income, and total income would increase by approximately 23 percent over the next 10 years in the area. NEGATIVE IMPACTS: Soil profiles would be completely altered and vegetation destroyed by mining operations on approximately 1,840 acres of land. Water quality would be affected by short- to long-term increases in suspended sediments and turbidity, as well as accelerated local erosion, resulting in a possible increase in sediment (1,852 tons per day) introduced into the stream bypass in the vicinity of the disturbed area. The impact on chemical water quality is not known. Approximately 347 acres would regrow as riparian tall shrub within 30 years of reclamation, and an additional 600 acres would regrow within 50 years on mining disturbance in creek bottoms. Approximately 1,354 acres of new mined land would remain barren or sparsely vegetated. Approximately 6,258 acres of wildlife habitat would be physically altered due to mining in the watershed. Periodic disturbance to wildlife due to the operation of vehicles and machinery and human activities would affect as much as 223,000 acres. Approximately 947 acres of moose habitat would be lost, and 20 miles of stream would be altered. Some subsistence activities would be affected, and visual quality in the area would decline.

AN - 36407057; 1864 AB - PURPOSE: Implementation of a flood control project in the Devils Lake basin of North Dakota is proposed. The basin lies in the northeastern portion of the state and in the northwest corner of the Red River of the North basin. It is bounded on the south by the Sheyenne River, on the north by the Pembina River basin, and on the east by the Park, Forest, and Turtle river basins. Although historically Devils Lake has been considered a part of the Red River basin, at present it is a closed drainage system. Flooding in the vicinity is caused by rising levels of Devils Lake that appear to result primarily from climate variations. The preferred plan would involve excavation of an outlet channel from Devils Lake to the Sheyenne River and a connecting channel from East Devils Lake to the Stump Lakes, elevation of East Stump Lake by 10 to 15 feet, excavation of a water quality outlet channel from the Stump Lakes to the Sheyenne River, voluntary evacuation around the low-lying areas of the Devils Lake chain, implementation of upstream drainage controls, and floodplain zoning around the main Devils Lake chain. The Devils Lake outlet channel would extend 17.5 miles; four segments would be distinguishable: (1) the approach channel segment, (2) the Round and Long lakes pool segment, (3) the Stony Lake pool segment, and (4) the gravity flow exit channel segment. Two pumping stations would serve the channel. The connecting channel from East Devils Lake to the Stump Lakes would consist of a gravity flow trapezoidal channel approximately 10 miles in length. Residential evacuations would constitute a part of the floodplain regulation plan. The outlet from East Stump Lake, which would be a buried pipeline served by a pumping plant, would extend to Tolna Creek. The cost of the project is estimated at $28.8 million, and the benefit-cost ratio is estimated at 1.3. POSITIVE IMPACTS: Plan implementation would represent a comprehensive approach to reducing flood damages associated with rising levels of Devils Lake. Environmental, economic, social, water quality, and hydrologic requirements of the basin would be met. Tangible accomplishment of the plan would include reduction of high lake levels and associated flood damages, as well as improvement of water quality, waterfowl habitat, and fishery resources. Recreational facilities and transportation routes would be protected from inundation, and access to the lake would be maintained. Portions of the plan would be complementary to plans designed to bring water into the basin to help stabilize the lake during extended dry periods. NEGATIVE IMPACTS: In addition to the relocation of more than 40 residences due to floodplain zoning requirements, the project would result in the loss of woodland, grassland, and wetland habitat.

AN - 36402663; 1844 AB - PURPOSE: Improvement and relocation of approximately six miles of existing Hoadly Road (Route 642) in Prince William County, Virginia are proposed. Hoadly Road acts as a collector route for subdivision traffic going to and from Route 234. The project would upgrade the facility to provide a four-lane divided highway with both raised and flush medians. More specifically, the new roadway would extend along Hoadly Road from Route 234 to Davis Ford Road, then run south along Davis Ford Road to Route 641. Both Hoadly and Davis Ford roads are currently two-lane facilities. Both roadways would be widened to four lanes, and Hoadly Road would be realigned. Several intersections along the route would be altered; these intersections would include Route 641, Route 543, and Dumfries Road. The completed roadway, which would follow both existing and new alignment, would consist of four 12-foot lanes, two in each direction, separated by a 16-foot median. Access would not be limited. The estimated cost of construction is $18.76 million. POSITIVE IMPACTS: Project implementation would replace a poorly aligned cross-country road, connecting Route 234 and Davis Ford Road, with a modern, safe highway facility. Recent and anticipated residential development along the western portion of Hoadly Road would be supported. Realignment of several intersections would improve the visual quality of the route. Traffic volumes anticipated for the corridor for the year 2010 would be accommodated. NEGATIVE IMPACTS: Rights-of-way requirements would displace terrestrial habitat and farmland and 12 to 16 families, and 2,000 square feet of emergent wetlands could be impacted. Noise levels associated with traffic using the facility would impact 49 to 63 residences. Because of its closer location to new homes and subdivisions than the current highway, the facility would result in some aesthetic impacts.

There were significant sublethal effects associated with exposure of the test organisms to fractions of sediments taken from certain stations in the Port of Hampton Roads. The respiration rates of the grass shrimp populations were depressed dramatically upon exposure to the liquid and suspended solid fractions of sediments from the most highly industrialized region of the Southern Branch of the Elizabeth River. Likewise, he hyporegulation capacity of grass shrimp exposed to high salinities declined following exposure to the elutriates from the same stations. The low levels of mortalities was apparently due to the removal of the most highly contaminated sediments by maintenance dredging operations 4-6 months prior to the tests. Lethal effects of the sediments were observed to return during tests 18 months following dredging. The sublethal effects of the sediments appear to be negligible in a region of the Southern Branch where the River makes a right angle turn and the sediments are somewhat sandy. The stations further upstream produced moderate sublethal effects, but only low levels of mortalities. The relative quality of the sediments which would be dredged during any future harbor deepening operations appears to be quite good. The sublethal effects of sediments composited to a depth of 3m did not produce significant sublethal effects. The toxic agent(s) producing respiratory depression and diminishment of osmoregulation capacity is unknown, but previous investigations indicate that this type of sublethal response is not uncommon and may be produced by different types of pollutants.

During the 1982-1984 seaward migrations of juvenile fall and spring chinook salmon Oncorhynchus tshawytscha, an array of physiological measurements (plasma cortisol and glucose , white blood cell counts) and challenge tests (saltwater challenge, secondary stress, and swimming endurance) were used to identify the stressful elements in these activities. Sequential increases in plasma cortisol titers of fish sampled at the physically separable points in the collection led to the conclusion that the elements of the system stressed fish cumulatively. Furthermore, there were decreases in numbers of white blood cells, in osmoregulatory ability, and in swimming endurance during the first 24 h after fish were collected. Increasing the water flow rate in the system after the 1982 season seemed to reduce total stress. The most stressful event in transportation appeared to be the loading of fish into a tank or truck barge. Fish recovered from the stress of loading while en route, and thus recovered more fully during the 16-h trip by barge than during the 3-h trip by truck. Physiological responses did not differ in fish transported in trucks at densities of 0.02-0.36 kg/L. Although there were no significant differences between the responses of fish collected at various times during the migrations, apparent differences between the responses of fall and spring chinook salmon suggested that the latter were more sensitive to the stresses of collection.

In the model, the transport of the surface oil slick is simulated by a Lagrangian discrete-parcel algorithm. The model simulates either continuous or instantaneous oil spills and can be used for both open water and ice-covered conditions. Oil slick transformation processes considered in the model include advection, mechanical spreading, horizontal turbulent diffusion, evaporation, dissolution, and shoreline deposition. The model can be used to develop cleanup measures in the case of an actual spill and to assess likely environmental impacts of possible spills.

AN - 36401016; 1865 AB - PURPOSE: Implementation of a flood control plan to address flooding problems along Coal Creek and its tributary, Dutch Creek, in Henryetta, Oklahoma is proposed. The watershed under consideration lies in the east-central portion of the state and the southern part of Okmulgee County. The total drainage area of Coal Creek is 74 square miles. Flooding along Coal and Dutch creeks occurs on an average of approximately once every five years. Most of the floods result from intense rainfall from thunderstorms that occur between April and September. The selected flood control plan would involve excavating a 1.3-mile trapezoidal channel generally between Main Street and Interstate 40 (I-40). The channel would have a bottom width ranging from 30 to 70 feet and one (vertical) on three (horizontal) side slopes. The top width of the channel would average 130 feet. The side slopes of the channel would be planted with grass, except for two 100-foot sections on each side of I-40; the two sections would be riprapped. The channel would generally follow the existing streambed of Coal Creek, except for a 500-foot cutoff located midway between F Street and Lake Road. The cutoff would reduce the length of Coal Creek by approximately 2,000 feet. An embankment would be constructed across the ends of the oxbow formed by the cut-off channel. A 24-inch-diameter conduit would be placed under the embankment at each end of the oxbow to provide for low flows through the oxbow, and an easement would be acquired on the oxbow to preserve fish and wildlife habitat. A total of 28 acres of perpetual easements would be established in association with the project. Material excavated from the channel would be dumped in an abandoned strip mine located approximately one mile east of Henryetta. The cost of plan implementation is estimated at $1.36 million, of which $922,000 would be borne by the Federal Government. The estimated benefit-cost ratio for the project is 1.4. POSITIVE IMPACTS: Annual flood damage along Coal Creek would decline from $740,000 to $551,000, based on March 1987 price levels. A minimum of 10-year in-bank flood protection would be provided between Main Street and the Missouri-Pacific Railroad. Residential, commercial, and public structures within Henryetta would be protected. Expected increases in flooding along Coal Creek, due to acceleration of development within the watershed, would be forestalled. NEGATIVE IMPACTS: Loss or reduction of riparian and bottomland hardwood forest and associated wildlife habitat as a result of channelization would decrease the productivity and diversity of terrestrial species. Approximately 10 acres of woody riparian vegetation would be displaced. Additional reductions in habitat and populations would result if flood protection were to promote significant land use changes. Aquatic habitat productivity would decline as well, due to replacement of pools and riffles and protective bank cover by a relatively sterile, straight channel, which would lack sufficient water depth to provide good aquatic habitat. Water temperatures within the channel would increase over those in the natural stream. Clearing of trees would exacerbate the discontinuity of the already poor quality riparian habitat zone along Dutch Creek. Telephone, water, sewer, gas, and electric power lines would have to be relocated.

A resource-use master plan, defining opportunities for recreational developments, has been prepared in lieu of specific recreation plans for Seven Oaks Dam and Prado Reservoir. Along the Lower Santa Ana River Channel, the recreation plan would provide for bicycle-hiking trails. On Santiago Creek, the recommended recreation plan would consist of a bicycle trail along the upper channel and around the perimeter of the gravel pits, in addition to a rest stop at the pits. The estimated cost of the project is $936.8 million, and the benefit-cost ratios for the Santiago Creek and Lower Santa Ana River portions of the project are 8.0 and 3.0, respectively. This supplemental draft environmental impact statement addresses minor alternative measures under the project design, refines baseline studies and mitigation plans, reassesses mitigation for impacts due to construction of the Seven Oaks Dam, meets added study commitments made in prior environmental documents on the project, addresses the situation with three newly listed endangered species, and modifies or confirms previous environmental features relative to changes that have occurred in the existing and future environments. POSITIVE IMPACTS: Plan implementation would provide flood protection to urban areas in the three-county area, with emphasis on the heavily urbanized Lower Santa Ana River Basin in Orange County. Habitat for endangered species in the Santa Ana Wash and elsewhere would be protected. Other mitigation measures would protect or enhance 133 acres of vireo habitat, 1,100 acres within the Santa Ana Canyon, 84 acres of Santa Ana salt marsh, and 5 acres of pond. Up to 3.0 million cubic yards of beach sand for beach replenishment would be available due to project excavation. Numerous recreational opportunities would be created. NEGATIVE IMPACTS: Construction and expansion of the reservoirs would require relocation of homes and businesses and elimination of farmland. In addition, the project would result in significant losses of wetland and other wildlife habitat and destruction of cultural resource sites, and would degrade the historical integrity of the Southern California Edison hydroelectric system.

Preparation date: April 22, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GRAYS HARBOR, WASHINGTON NAVIGATION IMPROVEMENT PROJECT: CHEHALIS AND HOQUIAM RIVERS. (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF SEPTEMBER 1982). AN - 36388776; 1794 AB - PURPOSE: Widening and deepening of the existing federal deep-draft navigation channel at Grays harbor on the Washington coast is proposed. This draft supplement to the final environmental impact statement (EIS) of September 1982 updates the description of impacts that are expected to result from the project. The existing channel extends from the Pacific Ocean through Grays Harbor up the Chehalis River to Cosmopolis. The recommended plan would involve: widening and deepening 23.5 miles of existing channel from the ocean bar to Cosmopolis; expanding the Cow Point and Elliott Slough turning basins; deepening local ship berthing; modifying the Union Pacific Railroad bridge at Aberdeen by replacing the existing swing-span with a lift-span bridge; modifying fendering around the north pier of the Highway 101 bridge in Aberdeen; removing two old highway bridge piers on the north bank at a point 1,500 feet upstream of the Highway 101 bridge; and relocating utility lines under the channel in the Aberdeen area. The portion of the channel from South reach to Cosmopolis is presently maintained annually; the entrance reach and bar are self-maintaining as a result of jetty systems. The channel would be dredged to the following dimensions: the ocean bar, 46 feet deep and 1,000 feet wide; the harbor entrance, 46 to 36 feet deep and 600 to 1,000 feet wide; the outer harbor, 36 feet deep and 350 feet wide; and the inner harbor, 36 feet deep and 250 to 350 feet wide. During the first year following channel widening and deepening, new maintenance dredging of 1.17 million cubic yards (c.y.) would be required over and above the 1.68 million c.y. of material now being removed annually. Over the following four years, additional dredging would decrease to 770,000 cubic yards. Construction dredging would be accomplished by hopper, clamshell, and cutterhead-suction/pipeline dredges, with disposal of dredged material at two ocean, two harbor open-water, and two confined disposal sites. Maintenance dredging would be performed by hopper and clamshell dredges, with disposal at one ocean and two harbor open-water sites. The project would include components to mitigate damage to Dungeness crab fishery losses and losses of salmon habitat. The estimated cost of the project is $59.1 million, and the benefit-cost ratio is estimated at 1.7. POSITIVE IMPACTS: Dredging to enlarge the navigation channel would improve safety within the harbor and reduce the potential for vessel-bridge collisions, reduce transportation costs for goods accommodated by the harbor, and reduce the existing potential for undermining the South Jetty. NEGATIVE IMPACTS: Dredging and disposal activities would result in a loss of 77,600 harvestable crabs during construction and 204,300 harvestable crabs during 50 years of incremental future operations and maintenance. The project would also adversely affect approximately two acres of subtidal habitat. Dredging and disposal operations would result in temporary turbidity and destruction of benthos.

Preparation date: April 19, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SMALL BOAT HARBOR, CHIGNIK, ALASKA. AN - 36404236; 1775 AB - PURPOSE: Harbor development at Chignik, Alaska, located on the Pacific side of the Alaska Peninsula at the head of Anchorage Bay, is proposed. Since Chignik is accessible only by air or sea, no boat launching facilities would be required. One structure would be needed to provide necessary protection for the inner harbor. A 1,460-foot rubblemound breakwater would be developed for a nonbreaking wave height of 8.5 feet. The side slope of 1 vertical to 1.5 horizontal would be stable; the design crest elevation would be 20.5 feet above mean lower low water. The mooring area would total 4.8 acres, using conventional double-berth mooring for 55 vessels from 31 to 60 feet long, and single- and double-berth mooring for 15 larger vessels up to 120 feet long or more. The entrance and access channel area would be approximately 3.6 acres; it would be cut through the nearshore zone and would be subject to the erosive effects of wave conditions. The length-to-width ratio of the basin would be 3.2. Circulation would be improved by several design characteristics. The entrance would be aligned so that the inflow direction is parallel to the long axis of the basin, designed to allow two-way traffic for the 85-foot design vessel. A staging area of 4.4 acres would be needed for minimal parking, gangway access, and some storage. The total area covered would be 26 acres. Total project costs are estimated at $10.0 million to construct, with a benefit-to-cost ratio of 1.2. POSITIVE IMPACTS: Under the preferred alternative, the harbor would provide protection at all times for vessels 30 feet to more than 120 feet long. The breakwater and inner harbor facilities would be designed for a 50-year storm event. The harbor would allow the local fishing fleet year-round harborage in Chignik. Residents in the area would be less dependent on private docks for anchorage and storage. A harbor would benefit the economy of the region. NEGATIVE IMPACTS: Indirect wildlife effects would be caused by close proximity to the harbor, such as increased noise, littering, and human traffic. Intertidal/subtidal habitat would be lost by dredge and fill activities, amounting to approximately 26 acres. There would be a significant impact on locally used clam beds. Harbor-related pollutants could enter harbor waters. Passerines, waterfowl, shorebirds, and seabirds might be dislocated because of construction activities and harbor operation. Maintenance dredging would be necessary over the life of the project.

Preparation date: April 18, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PORT JERSEY CHANNEL, BAYONNE, NEW JERSEY. AN - 36396961; 1786 AB - PURPOSE: A plan of improvement is proposed to realign, widen, extend, and deepen the existing Port Jersey channel to 41 feet mean low water (MLW) within the Upper New York Bay at Bayonne and Jersey City, New Jersey. The Port Jersey access channel is presently at an average depth of 35 feet MLW. The proposed plan recommends dredging to the optimal depth of 41 feet; 2 feet of overdepth dredging would also be included within the channel. The interior channel would be widened to 300 feet to provide access to all potential users (Global Terminal & Container Services (GT&CS), Military Ocean Terminal (MOT), and the Port Authority of New York and New Jersey). The northern limit of the proposed channel would be 110 feet from and parallel to the GT&CS bulkhead, providing a 110 foot berthing area. The southern limit would be 200 feet from the MOT bulkhead. At the eastern end of the inner channel, the channel bends 12.5 degrees; at the apex of the bend, the width of the channel is 400 feet. The outer channel is 300 feet wide from the main bend to a point 1,000 feet from the end of the channel, where it begins to widen to a width of 1,140 feet perpendicular to the east end of the channel. The turning basin at the west end of Port Jersey Channel would be 1,200 feet in diameter. Ocean disposal of dredged materials is also proposed. Results from bioassay tests indicate no problems with the disposal of dredged material from the channel to dump sites at sea. It is estimated that approximately 1.32 million cubic yards would be dredged from the proposed 43-foot deep (41 feet, plus 2 feet overdepth) channel. Total first costs are estimated at $13.36 million, for a benefit-to-cost ratio of 10.4. POSITIVE IMPACTS: By deepening the Port Jersey Channel, the ocean transportation costs associated with the movement of imports to and exports from the GT&CS marine terminal would be reduced. Waiting times required for tides, to ensure adequate clearance of vessels using the channel, would be reduced. These waiting times have an effect on costs, which would be reduced by deepening the channel. NEGATIVE IMPACTS: Benthic organisms would be harmed by turbidity, sedimentation, and bottom removal during dredging operations. Possible oil discharges from vessels would be harmful to all types of marine life, particularly in the intertidal zone. Dredging activities, as well as ocean disposal, are expected to result in short-term effects on water quality.

Preparation date: April 18, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PLACER MINING ON THE BEAVER CREEK WATERSHED, ALASKA. AN - 36388971; 1731 AB - PURPOSE: Implementation of a plan is proposed to continue management of mining claims on federal land within the placer mining area of the Beaver Creek watershed located approximately 50 air miles north of Fairbanks, Alaska and encompassing nearly 1.2 million acres of land. Most of the upper portion of the drainage lies within the White Mountains National Recreation Area. Under the preferred plan, mining claims on federal lands would continue to be managed as they were during the summer of the 1987 mining season. Placer mining in the Beaver Creek drainage would be managed according to federal and state water quality standards, with variances for the operation. The performance standards are 0.2 milliliters per liter of settleable solids and five Nephelometric Turbidity Units (NTUs) above natural conditions when natural turbidity is 50 NTUs or less, and not more than a 10-percent increase in the turbidity when the natural turbidity is 50 NTUs, not to exceed a maximum increase of 25 NTUs at the mine effluent discharge point. Reclamation activities would reshape tailings to approximate the surrounding physiography and spread the overburden and available topsoil over the reshaped tailings. Settling ponds would be similarly reclaimed. The stream bypass would be stabilized or reinforced to make it the permanent channel. The reclaimed site would be allowed to revegetate naturally. Under the proposed action, it is estimated that a total of five mines would be operating continuously over the next 10 years. The annual cost for each of the five operations would be $26,000 for water treatment and $10,000 for reclamation. Administration and enforcement of the surface mining plan would cost the Federal Government approximately $9,000. All estimates are in 1987 dollars. POSITIVE IMPACTS: Mining in the area would result in the recovery of $500,000 in gold from the Beaver Creek Drainage. If the number of mines increases from one to five, direct employment would increase by 38 work months per year and annual wages would increase by an estimated $45,000. NEGATIVE IMPACTS: Soil profiles would be completely altered by mining operations on approximately 115 acres of ground. There would be short- and long-term increases in suspended sediment and turbidity, and accelerated local erosion would result in a possible increase in sediment, introduced into the stream bypass in the vicinity of the disturbed area. Vegetation cover in mined and roaded areas would be destroyed. Twenty-eight acres of riparian tall shrubs would be affected for up to 30 years, and an additional 8.6 acres would be affected for up to 50 years. Ten years after plan implementation begins, 78 acres of land disturbance from mining operations would still be sparsely vegetated. Approximately 676 acres of wildlife habitat would be altered, resulting in a loss of 115 acres of moose winter range for a period of 50 years. The visual quality of the area would decline slightly.

Preparation date: April 14, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD DAMAGE REDUCTION ALONG SWAN CREEK, TOLEDO, LUCAS COUNTY, OHIO. AN - 36407519; 1793 AB - PURPOSE: Implementation of flood control measures along Swan Creek in the Heatherdale area of the city of Toledo, Lucas County, Ohio is proposed. The recommended plan would involve construction of approximately 3,100 feet of flood protection consisting of a combination of levee and floodwall sections along the left bank of Swan Creek, channel relocation along 500 feet of the right bank, and internal drainage features, including three outfalls and a small ponding area. The levee section would extend approximately 2,900 feet, while the floodwall would extend approximately 200 feet. The levee crest elevation would gradually increase from 597.0 National Geodetic Vertical Datum (NGVD) at the downstream end of the project to 598.0 NGVD at the upstream end. The floodwall, consisting of concrete-faced steel sheet pile, would be located adjacent to the Bethel Lutheran Church. Riprap erosion protection would be placed along approximately 1,300 feet of creek bank. Approximately 500 feet of channel relocation would be required in the vicinity of the intersection of Glencove and Heatherdale drives. The ponding, which would cover 1.6 acres and have a capacity of 9 acre-feet, would be located immediately east of Lomond Drive. Land requirements would include acquisition of permanent easements on 6.0 acres and temporary easements on 4.4 acres, and fee simple acquisition of 3.3 acres. The Hoffman Road Landfill would be used for borrow material and disposal of project debris. The cost of the project is estimated at $1.47 million, and the benefit-cost ratio is estimated at 1.14 at an interest rate of approximately 8.6 percent and at 1.11 at an interest rate of approximately 8.8 percent. POSITIVE IMPACTS: Project features would provide protection from a flood event occurring once every 100 years. With existing average annual damages of $172,630 and residual average annual damages of $10,230, the recommended 100-year levee plan would eliminate approximately 94 percent of the average annual damages in the Heatherdale area. Benefits include flood reduction, elimination of flood insurance costs, and generally increased affluence in the protected area. Riprap bank protection would diversify benthic habitat along the creek. Nonpoint source water pollution of Swan Creek would decline. NEGATIVE IMPACTS: Six acres of floodplain habitat, 2,500 linear feet of streambank vegetation, and one acre of privately managed upland habitat would be cleared prior to construction. Construction activities would disturb benthic communities and reduce air and water quality in the vicinity of project activities. Access to the Swan Creek streambank would be impeded by the levee and floodwall, and 2.6 acres of open space would be lost to public use.

AN - 36400127; 1725 AB - PURPOSE: Expansion of the capacity of the Pacific Northwest-Pacific Southwest Intertie and development of a Long Term Intertie Access Policy (IAP) are proposed by the Bonneville Power Administration (BPA). The Long Term IAP would apply only to those portions of the Intertie owned by BPA. These proposals would enable short- and long-term contractual sales and transfers of surplus federal power and management of other interregional transfers of power over the Pacific Northwest-Pacific Southwest Intertie. Intertie capacity, presently 5,200 megawatts (MW), would be increased to 7,900 MW, and a formula allocation and firm sales provision would be adopted. BPA would participate in upgrading Intertie facilities to the capacity required. Power from new resources would be allowed on the Intertie only on an hourly basis or to sustain assured delivery contracts previously established on the basis of currently existing firm surpluses. To ensure protection of fish and wildlife resources in the Columbia River Basin, the allocation of any utility constructing a new hydroelectric project in an area designated as protected would be decreased by the generating capacity of that project. Average annual sales from the Pacific Northwest (PNW) to California would be approximately 123 to 135 percent of the current level; these figures are based on forecasted sales for study years 1993, 1998, and 2003. BPA-funded measures would be taken to mitigate IAP effects on resident fish and Hungry Horse Reservoir. POSITIVE IMPACTS: A consistent policy for administering the Intertie would be implemented. The increased capacity of the Intertie would result in gains of approximately $2.0 billion in benefits relative to the existing capacity. Intertie system flexibility and reliability would be enhanced. Capacity increases would decrease air pollution associated with electric generation in southern and north-central California. Management activities would reduce impacts to cultural resource sites due to vandalism. Development of new power resources in the PNW would increase somewhat. Fish and wildlife protection features of the IAP would discourage construction of new and expansion of existing nonfederal hydroelectric facilities that could interfere with the goals of the Columbia River Basin Fish and Wildlife Program and undermine BPA investments. NEGATIVE IMPACTS: Changes in hydroelectric operations would have minor adverse effects on some anadromous and resident fish stocks in the PNW. Wave erosion would damage some cultural resource sites. Development of new power resources in California and the Inland Southwest would be somewhat retarded. LEGAL MANDATES: Bonneville Project Act of 1937 (16 U.S.C. 832a(a) et seq.).

Preparation date: April 8, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OPERATION AND MAINTENANCE OF FEDERAL NAVIGATION FACILITIES AT SAULT STE. MARIE, MICHIGAN (DRAFT SUPPLEMENT II TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1977). AN - 36405663; 1784 AB - PURPOSE: Extension of operations of the locks at Sault Ste. Marie, Michigan to as late as January 31 (with a possible additional extension through February 14) is proposed to allow additional vessel transits in response to the reasonable demands of commerce. Currently, operations are terminated after January 8 (with a possible extension to January 15). This second draft supplement to the final environmental impact statement (EIS) of July 1977 addresses a proposed change in the plan of operation of the federal facilities at Sault Ste. Marie. Specifically, it addresses potential environmental impacts due to the proposed extension of annual operations. The supplement also contains additional information not incorporated into the original final EIS or the first supplement addressing the extension of lock operation to January 8 (with a possible extension to January 15). Environmental studies were conducted to evaluate potential adverse impacts of the extension. These studies focused on the upper Great Lakes connecting channels, namely, the St. Marys River, St. Clair River, Lake St. Clair, and the Detroit River. It had been determined from previous studies that it was in these channels that navigation under winter conditions would be most likely to have adverse impacts. Due to concerns about unforeseen, possibly cumulative adverse effects from vessel passage during periods of ice formation, considerable effort was put forth to obtain all necessary descriptive and analytic information to evaluate the potential effects. In addition to studies on current resources, a historical study of wetland resources was completed. A mathematical model was created for evaluating vessel effects under ice conditions. An oil and hazardous materials spill model was created for analysis of potential impacts, and risk analyses were conducted for oil and hazardous material spills. POSITIVE IMPACTS: Extension of lock operations would benefit industry and commercial navigation by allowing for greater use of low-cost waterborne transportation to and from Lake Superior ports and reduction of winter stockpiling costs. Industrial and commercial shipping concerns could take advantage of up to a month of additional shipping time for vessel traffic passing through the Sault Locks. NEGATIVE IMPACTS: Deer on Neebish and Sugar islands could be adversely affected during years in which traffic levels through the locks were significantly increased over normal traffic levels. High traffic levels could result in blockage of deer attempting to cross the shipping channel to Neebish Island in early January. Some Neebish Island deer could be isolated from browse on St. Joseph Island. Benthic communities, water quality, and submerged aquatic plants could be affected within a short reach of the St. Marys River. Some shore structures located near the navigation channel could be subjected to increased winter damage.

Preparation date: April 7, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LONG-TERM MAINTENANCE OF WILMINGTON HARBOR, NEW HANOVER AND BRUNSWICK COUNTIES, NORTH CAROLINA. AN - 36381778; 1791 AB - PURPOSE: Implementation of a plan to maintain the Wilmington Harbor via dredging and disposal operations in the waters of New Hanover and Brunswick counties, North Carolina is proposed. Approximately 2.3 million cubic yards of sediment are dredged from the navigation project annually in order to maintain its authorized dimensions. The depth and width of the navigation channel have been increased several times and now can handle ships with drafts of up to 38 feet. The 30.8-mile-long project consists of a channel, 40 feet deep and 500 feet wide, through the ocean bar, thence up the Cape Fear River at a depth of 38 feet and a width of 400 feet, with increased widths at bends, to the upstream end of the anchorage basin at the foot of Castle Street. The anchorage basin at Wilmington is 38 feet deep, 2,000 feet long, and 900 feet wide at the upstream end and 1,200 feet wide at the downstream end. The approaches to the anchorage basin are 1,500 feet long at the upstream end and 4,500 feet long at the downstream end. In the reach from Castle Street upstream to the Hilton Bridge, the authorized channel is 32 feet deep and 400 feet wide, with increased widths at bends. In this reach, there is a turning basin opposite the principal terminals at Wilmington, authorized at 32 feet deep, 1,000 feet long, and 800 feet wide, with suitable approaches at each end. From the Hilton Bridge to the upstream end of the project (1.67 miles above the Hilton Bridge), the channel is 25 feet deep and 200 feet wide. A turning basin, 25 feet deep, 700 feet long, and 500 feet wide, is located 1.25 miles above the Hilton Bridge. Two feet of overdepth is generally authorized throughout the project, except in areas of rock and at the ocean bar, where three feet of overdepth is authorized. The Anchorage Basin and Between Channel are dredged annually, while maintenance dredging of individual channels in the 38-foot project has usually been performed every two years. The 50-year dredging and disposal plan would involve the use of hopper, hydraulic pipeline, and bucket dredges. Dredged material would be dumped in a designated ocean disposal site or in diked upland sites. All disposal sites have previously been used for disposal of dredged material. Some material could be used for beach replenishment. POSITIVE IMPACTS: Revenue derived from harbor operations, which in 1982 amounted to $900 million in salaries and benefits and $117 million in local and state taxes, would continue to redound to local and regional interests. NEGATIVE IMPACTS: Potential adverse impacts associated with continued maintenance dredging would be largely related to disposal of 2.3 million cubic yards of dredged material each year.

Preparation date: April 5, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 228 FROM ROUTE 360 TO INTERSTATE 64, CITY OF RICHMOND AND CHESTERFIELD, HENRICO, GOOCHLAND, AND POWHATAN COUNTIES, VIRGINIA. AN - 36402971; 1767 AB - PURPOSE: Construction of Route 288 in the city of Richmond and Chesterfield, Henrico, Goochland, and Powhatan counties, Virginia is proposed to provide for north-south travel between Route 360 and Interstate 64 (I-64). The study corridor extends approximately 17.5 miles, 60 percent of which lies to the south of the James River and 40 percent to the north. Route 288 would provide full-control-access features, including interchanges at major crossroads. The freeway would have four to eight lanes and meet all interstate freeway standards for line, grade, and geometric features to provide for a design speed of 70 miles per hour. Four alternatives are under consideration. Noise barriers could be included in the design of the project. Estimated costs of the project range from $171.2 million to $246.8 million, depending on the alternative chosen. POSITIVE IMPACTS: Forming the southwest link of the Route 288/I-295 freeway network in the Richmond metropolitan area, the highway would meet existing and projected traffic volume demands for the study area. Congestion on existing routes would be relieved by redistribution of traffic patterns, and safety and efficiency of the area's transportation system would be improved. Intraregional access across the James River west of the Parham/Chippenham Connector would be enhanced significantly. One alternative alignment would serve as a bypass route between I-64 and the proposed Ridgefield Parkway. The annual accident rate in the corridor would decline by 165 incidents per year, and travel costs would drop by $6.5 million. NEGATIVE IMPACTS: Rights-of-way development would result in displacement of 4 to 14 businesses, employing 10 to 28 workers, and 18 to 39 households. Three of the alternatives under consideration would result in relocation of the Swift Creek Athletic Association Soccer Complex. Tax revenue losses due to rights-of-way acquisition would range from $127,000 to $194,000 per year. A total of 851 to 932 acres of land would be acquired. Land displaced would include forest, old field habitat, prime farmland, pastureland, and cultivated fields. Numerous streams and wetlands would be crossed, impacting 12.1 to 24.2 acres of wetland. One minority community would be impacted, and up to three communities could be severed. Presence of the freeway could result in acceleration of local development and related indirect environmental impacts. School bus routes would suffer minor disruptions due to the barriers to local traffic movement created by the freeway. Up to 620 residential receptors could be subject to noise levels in excess of federal standards. The facility would encroach on land currently used for rural and suburban living. One alternative could have significant impacts on the Swift Creek Reservoir. Up to 3 significant architectural structures and 19 archaeological sites could be damaged.

The study looked at background water quality, the effects of ship passage, and sedimentation rates. Background water quality in the study area has been continually improving since 1967. There is significant seasonal variation in temperature and dissolved oxygen not related to shipping activity. The background variation in all characteristics studied during this project as reported to the Environmental Protection Agency 's STORET system was greater than any observed variation due to ship passages. Although seasonal variation is clearly evident for temperature and dissolved oxygen, no seasonal variation was evident for turbidity, suspended or volatile solids, or pH. It is concluded that natural background variation is greater than and independent of ship-induced variation.

AN - 36399837; 1789 AB - PURPOSE: Development of Davids Island, located in the western section of Long Island Sound in the city of New Rochelle, Westchester County, New York, is proposed. The Davids Island Urban Renewal Area consists of Davids Island and a 2.3-acre portion of the Fort Slocum Dock area. Davids Island encompasses 77.8 acres of land above mean high water (MHW), of which 42 acres are above the 100-year flood elevation. With the exception of 5.2 acres owned in fee simple by Consolidated Edison, Davids Island is owned by the city of New Rochelle. The proposed development plan would include construction of a bridge from the mainland to the island and associated bridge access roadways on the mainland, construction of 2,000 residential units and supporting nonresidential activities, construction of a marina and beach, provision of utilities, construction of a helipad, and improvements to the South Channel. The fixed-span bridge would be 3,465 feet long, commencing at the Fort Slocum Dock area and proceeding in an easterly direction along a route that brings the structure adjacent to the most northern area of Glen Island and over a 0.48 acre area of parkland that is normally covered with water at MHW and exposed at mean low water. Two bridge pile foundations would be placed within this area. The mainland approach to the Davids Island Bridge would be designed to provide two-way circulation. The residential units would include supporting retail, recreation, and open space uses. Population on the island is projected to be 3,700 persons. The western and southern shoreline of the island would be developed as a marina accommodating 800 slips for use by island residents.This draft supplement to the draft environmental impact statement of December 1986 addresses impacts of the project, including development of Davids Island and a marina, construction of a bridge between the New Rochelle mainland and Davids Island, development of a mainland roadway system, other improvements associated with the project, and modifications to the original design discussed in the draft statement. This supplement also includes a Section 4(f) evaluation describing the impact of the proposal on several parks in the vicinity of the project. POSITIVE IMPACTS: The city of New Rochelle would derive substantial economic benefit from the development of Davids Island. The long-term consequences of placing the island into development represents a conversion from its current status as undeveloped, underutilized, and blighted lands. Access to and from Westchester County's Glen Island Park would improve, and traffic backup on local streets would be reduced. New jobs, income, and housing would be produced. There would be a substantial increase in public tax revenues over and above public costs for the project, and New Rochelle's image would improve as a waterfront community in proximity to New York City. NEGATIVE IMPACTS: The primary negative impacts resulting from the development would include navigational and boating constraints associated with the clearance restrictions of the Davids Island Bridge; increased project-related traffic volumes on the mainland roadway system, with consequent increases in vehicular exhaust emissions and vehicular noise; the need for additional sewage treatment capacity at the New Rochelle plant; and impacts to the marine environment from dredging and rock blasting.

Preparation date: March 31, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RELOCATED MARYLAND ROUTE 32 FROM MARYLAND ROUTE 108 TO PINDELL SCHOOL ROAD, HOWARD COUNTY, MARYLAND (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1977). AN - 36403141; 1761 AB - PURPOSE: Improvement of Maryland Route 32 from Pindell School Road to Maryland 108 in central Howard County, Maryland is proposed. Maryland 32 extends from Westminster in Carroll County to proposed Interstate 97 near Annapolis in Anne Arundel County, a distance of approximately 59 miles. The relocated highway segment under consideration would begin at the existing northbound lanes of Maryland 32 just west of Maryland 108 and pass through the Trotter Road area approximately 2,360 feet north of existing Maryland 32. The alignment would proceed east through the vicinity of the W. R. Grace Property and Stretmater Pond, shifting north to avoid impacts to the pond and residences along the south side of old Maryland 32. The alignment would then proceed easterly to meet existing Maryland Route 32 construction east of Pindell School Road. Within this segment, full diamond interchanges would be constructed at existing Maryland 108 and Pindell School Road. The project would also include construction of two service roads, one connecting existing Maryland 32 to relocated Sanner Road/Pindell School Road on the south and the other on the north connecting Cedar Lane to the entrances to the W. R. Grace and Riverhill Game Farm properties. Relocation of Maryland 32 and the construction of service roads, together with Maryland 108 improvements, would be built to current state and federal highway standards. Improvements to Trotter Road and Pindell School Road would meet county standards. The typical roadway section for Maryland 32 would consist of two 24-foot roadway surfaces with a 46-foot median, and 4-foot inside and 10-foot outside shoulders within a minimum right-of-way of 300 feet. A box culvert would be constructed where relocated Maryland 32 would cross over Cricket Creek, and a bridge structure would carry relocated Pindell School Road/Cedar Lane over the Middle Patuxent River. The estimated cost of the project, in 1988 dollars, is $40.1 million; if service roads are included in the construction costs, the total project cost estimate would rise to $44.8 million. POSITIVE IMPACTS: Additional highway capacity would be available in central Howard County, a rapidly developing area within the Baltimore-Washington corridor. The existing two-lane segment would be replaced by a controlled access, high-speed, east-west facility, relieving much of the congestion on the existing roadway network by redirecting truck and commuter traffic. Traffic using relocated Maryland 32 would no longer be diverted through Clarksville. The completion of the project would create a continuous link between Interstate 70 near Cooksville in Howard County and the city of Annapolis in Anne Arundel County. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of one resident, 1 acre of public land, 29 acres of natural woodland habitat, 2.35 acres of wetlands, 8.01 acres of floodplains, and 2.32 acres of prime farmland. Eight streams would be crossed. Two archaeological sties would be affected by construction activities. Three noise sensitive areas would be exposed to traffic noise in violation of federal standards.

Preparation date: March 28, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BOSTON HARBOR, MASSACHUSETTS WASTEWATER CONVEYANCE SYSTEM (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1985). AN - 36397377; 1773 AB - PURPOSE: Upgrading of the Metropolitan District Commission (MDC) wastewater management systems, including sewer interceptors, wastewater treatment facilities, and sludge disposal facilities, in Boston, Massachusetts is proposed. This supplement to the final environmental impact statement (EIS) of December 1985 on the upgrading project addresses impacts of the wastewater conveyance system for the Greater Boston wastewater treatment facility. The final EIS recommended treatment of wastewaters from the entire Metropolitan Sewerage District service area at a centralized location at the Deer Island Plant. The plant would be expanded and upgraded to provide secondary treatment for an average daily flow of 586 million gallons. The final EIS on siting a secondary treatment facility for the harbor designated an area east of Deer Island for the discharge of effluent. The area had to be more precisely defined for evaluation in this draft supplemental EIS. This was done by establishing a limited area in Massachusetts Bay suitable for discharge of effluent from the secondary treatment plant on Deer Island. A landward or western boundary was established beyond which shoreline impacts could be avoided by minimizing transport of effluent to the shoreline, and water quality criteria goals could be achieved by providing a minimum initial dilution. The eastern or seaward edge of the area could not easily be established by application of a single criterion. The impacts from factors of concern, such as sediment and water quality and marine ecosystems, generally decrease along the gradient in an offshore direction. Costs increase along the same gradient. Therefore, a screening level analysis was performed comparing a secondary discharge at the nearshore and offshore regions. Three sites were identified for detailed evaluation. For approximately five years, while the secondary treatment plant is under construction, primary effluent would be discharged. The discharge location of interim primary effluent was also addressed in the screening analysis. The discharge conveyance system, proposed in this draft supplement, would consist of deep rock tunnels for the interisland and outfall conduits and a diffuser located at least seven miles east of Deer Island. In addition, a conduit would be constructed to deliver South System flows from Nut Island to the Deer Island Plant to effect consolidation of wastewater treatment for the entire service area. The estimated cost of the conveyance and outfall structures ranges from $276 million to $468 million. POSITIVE IMPACTS: Offshore release of primary and secondary effluent from the Deer Island facility would be, environmentally and economically, the most acceptable means of dealing with effluent from the treatment plant. NEGATIVE IMPACTS: Some effluent from the outfall would be transported back to the shoreline by currents, impacting recreational and other shoreline activities. Dredging associated with construction of the tunnel would result in disturbances of bay benthos and temporary turbidity. Some polychlorinated biphenyls would be released into the water column of the bay during outfall operation. Water quality standards for aquatic life and public health would be exceeded on occasion, and sediment enrichment would occur.

Preparation date: March 25, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CUCHILLO DAM, RIO GRANDE FLOODWAY, TRUTH OR CONSEQUENCES UNIT, SIERRA COUNTY, NEW MEXICO. AN - 36397016; 1787 AB - PURPOSE: Implementation of a plan to provide increased flood protection to the Truth or Consequences and Williamsburg areas of Sierra County, New Mexico is proposed. The preferred flood control alternative would involve construction of the Cuchillo Dam, to be located approximately three miles downstream of the village of Cuchillo in a canyon known locally as "the box." The dam would control approximately 90 percent (325 square miles) of the 360 square miles within the Cuchillo Negro watershed. The structure would consist of an earthfill embankment nonoverflow section with an off-channel emergency spillway. The dam would form a reservoir approximately 2.3 miles in length when the water level reaches the spillway crest. Of the total capacity of 13,500 acre-feet, 7,500 acre-feet would be used for flood control and the remaining 6,000 acre-feet would be allocated for sediment storage. The spillway crest would be at elevation 4,721.4 NGVD (National Geodetic Vertical Datum). At the maximum water surface elevation, the reservoir would have a capacity of 20,500 acre-feet and a total flood pool surface area of 520 acres. The nonoverflow section would consist of a roller-compacted concrete portion located in the mainstem canyon and rising 119 feet above the existing streambed. The downstream face would have a slope of 0.8 foot horizontal to 1.0 foot vertical. The earthfill embankment would be a zoned section having one 12-foot-wide crest and 3.0 foot horizontal to 1.0 foot vertical sideslope. An ungated outlet would be incorporated into the structure to pass flood flows through the reservoir without exceeding safe channel capacities downstream. The 73-foot-high reinforced concrete intake tower of the outlet works would have a trash rack to prevent large debris from entering the conduit. The outlet conduit would be 111 feet long, with a stilling basin for a terminal energy dissipator located at the downstream end. The estimated first cost of the Cuchillo Dam Reservoir is $14.6 million, and the annual charges are estimated at $1.46 million. POSITIVE IMPACTS: The recommended plan would alleviate most of the hazards related to the flood problem. It would improve the quality of water entering the Mim's Lake area and the Rio Grande by removing large percentages of silt borne by flood waters. The increase in riparian habitat would benefit wildlife. A detention dam on the Cuchillo Negro would reduce the amount of silt entering the Mim's wetland during floods, thereby extending the live of the wetland. The flood control measures would double the life of the marsh to approximately 200 years. A reduction of silt and sediment into the Rio Grande, resulting from the detention dam on the Cuchillo Negro, would benefit the fishery and lengthen the life of the Caballo Reservoir down river. Deposition of sediment could enhance vegetation growing in the flood pool area which, in turn, would benefit wildlife habitat. If wildlife numbers were to increase, the potential for more or better quality hunting would increase. Mitigation of damage to archaeological sites would produce important data for a relatively unknown portion of New Mexico. Significant geological and paleontological resources discovered within the project site would be excavated and documented. NEGATIVE IMPACTS: Windmills and other structures would have to be removed from the flood pool area to prevent possible obstruction of the dam's drain conduit. Nine residences in the Cuchillo Negro arroyo would have to be relocated; land required for the project would have to be acquired by the local sponsors. Agricultural and residential land uses within the project area would be curtailed.

Preparation date: March 25, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LAKE PONTCHARTRAIN, LOUISIANA AND VICINITY HURRICANE PROTECTION PROJECT: MITIGATION STUDY (DRAFT SUPPLEMENT II TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JANUARY 1975). AN - 36399719; 1782 AB - PURPOSE: Implementation of habitat mitigation measures in association with the Hurricane Protection Project for Lake Pontchartrain, Louisiana is proposed. This second draft supplement to the final environmental impact statement (EIS) of January 1975 on implementation of the hurricane protection project addresses the mitigation plan. The originally authorized hurricane protection plan consisted of placement of barrier structures in the Rigolets and Chef Menteur tidal passes and the Inner Harbor Navigation Canal. In addition, levees were to be built along the entire lakefront from Bonnet Carre Spillway to South Point, with a connection to the Mississippi River levees along the Inner Harbor Navigation Canal. Ring levees were to be built around the New Orleans East and Chalmette areas. The barrier complexes were challenged in court, and an injunction was placed against their construction. Upon reevaluation of the plan, the barrier complexes were abandoned permanently, and the project was confined to the raising of levees. The levee alignment in St. Charles Parish was moved from the lakefront to just north of Airline Highway (U.S. 61). Annualized losses due to measures under the project include 854 acres of brackish/saline marsh, 108 acres of fresh/intermediate marsh, 233 acres of marsh pond, and 134 acres of forested wetlands, for a total of 1,329 acres. Annual losses of habitat would amount to 2,610 average annual habitat units for seven wildlife species. The tentatively selected plan for mitigation of these losses would involve protection of approximately five miles of the Manchac Wildlife Management Area (WMA) from shoreline erosion, thus preserving 1,100 acres of wetlands annually. The shoreline lies along Lake Pontchartrain from First Canal to a point 2,000 feet south of the southernmost boundary of the WMA. A combination of rock dike and marsh grass plantings would provide protection to the shoreline. More specifically, shoreline protection would be provided via a series of rock dikes, each of which would be 2 feet high, 16 feet wide, and 200 feet long; 50-foot gaps would separate the dikes, which would be located approximately 180 feet offshore. Shoreline protection would be supplemented by planting of marsh vegetation in the area between the shoreline and the dike. Dredged material would be temporarily deposited along the edge of the flotation channel until dike construction was completed in order to allow rock-carrying barges to enter and leave the site. The dredge would then be used to backfill the channel following construction. The estimated cost of the mitigation measures is $6.9 million. POSITIVE IMPACTS: Provisions under the plan would mitigate nearly 100 percent of the damage resulting from the hurricane protection project. The plan would be responsive to all project planning constraints; effective and economically efficient; supported by state and federal interests; and located on public land. The plantings and bank protection would preserve wildlife and fishery habitat on 300 acres of marsh, 200 acres of cypress, and 600 acres of marsh ponds each year. The mitigation land would be accessible to residents of all affected parishes. A net gain of 12,500 person-days of sport fishing, 286,800 pounds of commercial fin and shellfish harvest, and 1,300 person-days of hunting and wildlife-oriented recreation would result. NEGATIVE IMPACTS: Construction of the flotation channel would result in significant, long-term violations of Louisiana State Water Quality Standards. Dike construction would disturb and displace lake bottom habitat.

Preparation date: March 21, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OAKLAND OUTER AND INNER HARBORS DEEP-DRAFT NAVIGATION IMPROVEMENTS, ALAMEDA COUNTY, CALIFORNIA (FINAL SUPPLEMENT I TO THE FINAL ENVIRONMENTAL IMPACT STATEMENTS OF SEPTEMBER 1979 AND NOVEMBER 1984). AN - 36402734; 1776 AB - PURPOSE: Deepening and widening of the existing Oakland Harbor channels in the Port of Oakland, California are proposed. The port lies on the east side of San Francisco Bay, near the western terminus of major rail and highway networks. This final supplement to the final environmental impact statements of September 1979 and November 1984 recommends a plan that would involve deepening navigation channels from 35 to 42 feet below mean lower low water between the entrance to the harbor via Bay Channel and Clay Street Piers and widening certain reaches of the channels to permit optimum use of restricted channel dimensions. Project dredging would occur over a 3.4-mile outer harbor channel and an associated turning basin and over 4.0 miles of inner harbor channel between the Entrance Channel reach and the Clay Street Pier. The channel would be widened at the Inner harbor entrance, at project mile 3.0 and at the upper end of the project, and an associated turning basin would be provided. The project would involve dredging approximately 7.0 million cubic yards of material via clamshell, hopper, and cutterhead dredges and transportation of the material to an ocean disposal site. The estimated cost of the project is $54.0 million. POSITIVE IMPACTS: Enlargement of the channels would eliminate tidal delays for 75 percent of all container vessels projected to be in service by 1996. As a result, waterborne transportation costs associated with the port would decline significantly. Widening of the channel would reduce the risk of navigational accidents. Commercial shipping through the harbor would increase. Estimated annual savings resulting from the project would amount to $26.5 million. NEGATIVE IMPACTS: Deeper channels would trap more sediment, increasing the cost of maintenance. Widening of the channels would subject undisturbed benthic habitat to periodic disturbance. Dredging activities would create turbidity, temporarily lowering ambient water quality and possibly disturbing slightly the foraging habits of a nearby colony of the California least tern, an endangered species. Ocean disposal of dredged material would result in bathymetric changes over 5.4 square nautical miles, possibly degrading habitat of the Dungeness crab and demersal fish.

AN - 36396921; 1780 AB - PURPOSE: Designation of the Brunswick, Georgia Ocean Dredged Material Disposal Site is proposed. Each year the entrance channel to Brunswick Harbor must be dredged due to natural processes that cause shoaling. Approximately 0.6 million cubic yards of sediment are dredged annually from the entrance channel and dumped at the Brunswick ocean disposal site. Material is dredged, transported, and discharged from underwater ports via hopper dredge within the boundaries of the disposal site. The existing site has been used since 1964. The site approved by the Environmental Protection Agency for interim use would be designated as the permanent ocean material disposal site. The rectangular site, lying in 30 feet of water, is located approximately six nautical miles southeast of Brunswick, Georgia. It is believed that net sediment transport from the site is to the south. Disposal operations would be regulated to prevent unacceptable environmental degradation outside site boundaries. POSITIVE IMPACTS: Final designation of the site would ensure an area for disposal of material dredged during maintenance of the Brunswick Harbor, which is one of Georgia's two major ports and vital to the economy of the South Atlantic region. NEGATIVE IMPACTS: Dumping of material at the proposed site would result in alteration of site topography via mounding, smothering of benthos at the site, and temporary disturbance of the water column due to turbidity and chemical releases as well as reduction of dissolved oxygen levels. Habitat at the site could be altered.

Preparation date: March 17, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - METROPOLITAN DENVER WATER SUPPLY SYSTEM, COLORADO. AN - 36403680; 1779 AB - PURPOSE: Permit applications have been filed by the Denver Board of Water Commissioners (Board) on behalf of the Denver Water Department (DWD) for the 1.1 million acre-foot Two Forks Reservoir and for an extension of its Williams Fork Gravity Collection System. These are considered to be two separate and distinct applications. The Metropolitan Water Providers, composed of more than 40 cities, water and sanitation districts, and 1 county in the Denver metropolitan area, are co-sponsors of the Two Forks project. The area includes all or parts of Denver, Adams, Arapahoe, Douglas, Jefferson, Boulder, and Weld counties in Colorado. The Two Forks damsite is located on the South Platte River approximately one mile downstream from the confluence of the North Fork of the South Platte River with the South Platte River. The Two Forks Reservoir would provide long-term storage of natural flows from the North Fork of the South Platte River and the South Platte River and would also store flows from existing west slope collection systems that deliver water to the North Fork of the South Platte River via Roberts Tunnel. Waters regulated by Two Forks would be diverted at Strontia Springs Dam to the Foothills Water Treatment Plant, to the Marston Treatment Plant, and at specified delivery points for suburban participants that are raw water users. Operation of the reservoir would increase the firm annual yield to the DWD system by 98,000 acre-feet per year. The Two Forks Dam would be a multicurvature, thin-arch concrete dam designed to be constructed in either one or two stages. Principal project features would be the concrete arch dam; a free overflow spillway in the center of the dam crest; a spillway plunge pool; a multilevel intake structure on the upstream face of the dam; valving systems for selective withdrawals from the reservoir, including an emergency reservoir drain system; a diversion tunnel and cofferdams for river diversion during construction; electrical transmission lines; and project access roads. The construction cost would be approximately $520 million. The Williams Fork gravity project would be an extension of the existing system. The project would be divided into the South and North sectors. Both sectors would be extensions of the existing gravity-flow system and would deliver water to the Gumlick Tunnel. The extended system would collect water from Darling Creek and the South Fork, Middle Fork, and main stem of the Williams Fork drainage. Extension of the Williams Fork Collection System, using the gravity scheme, would increase the safe yield of the DWD system by 12,000 acre-feet per year. The total construction cost of the project is estimated to be approximately $110 million. Mitigation would be required for wildlife transportation, aquatic habitat, and recreational and visual resources. POSITIVE IMPACTS: The Two Forks dam and reservoir would provide a 12-year supply of water for the Denver metropolitan area. This would be the most cost-effective alternative. The Williams Fork gravity project would provide metropolitan Denver water supply needs for one additional year. This alternative would benefit aquatic life. It would not cause significant impacts to physiography, topography, geology, channel stability, transportation, water quality, threatened and endangered species, or socioeconomic resources. NEGATIVE IMPACTS: Without considering mitigation, the Two Forks alternative would be the most damaging to recreation; threatened and endangered species; vegetation; wildlife; aquatic life; and visual, cultural, and water quality resources. This alternative would eliminate a number of recreational cabins, inundate miles of gold medal trout stream, cause the loss of suitable habitat for the pawnee Montane skipper butterfly, and eliminate acres of vegetation. It would also eliminate deer and elk winter range and bighorn sheep range.

AN - 36399630; 1750 AB - PURPOSE: Construction and operation of a destination resort on private land within the Toiyabe National Forest and Washoe County, Nevada is proposed. Application for a special use permit for a long-term lease of 633 acres of national forestland adjacent to the development site would also be made. The resort would be located in the upper Galena Creek basin, approximately 17 miles from Reno. At ultimate development, the resort would consist of three villages containing 2,310 hotel/residential units and commercial space, including conference facilities, casinos, restaurants, entertainment areas, and retail space, along with the associated infrastructure. Hotel/residential units would include 820 hotel rooms, 1,420 multifamily residential units, 70 single-family units, and 225,000 square feet of commercial space. Approximately 125 units of employee housing would also be provided. Recreation amenities would include a 15-lift downhill ski area, Nordic skiing provisions, ice skating facilities, an 18-hole golf course, tennis courts, and other sports/recreational provisions. Restaurant, casino gaming, and entertainment areas would also be included in the complex. Infrastructural requirements would include water and sewer pipelines, roads, and underground utility cables. Construction would be phased over 10 to 12 years. The first phase of the development, which would extend through the fifth year of development, would include the initial components of one village, approximately one-half of the ski area, and the golf course. The opening ski area would have a capacity of 5,560 skiers utilizing 257 acres of trails and six ski lifts. Average annual construction thereafter would consist of approximately 200 unit equivalents and 25,000 square feet of commercial space. Depending on future conditions, the number of units and density could vary somewhat in accordance with the previously approved Washoe County special use permit. The ultimate three-village complex would be linked by roadways and recreation systems to create a cohesive destination recreational resort community. Of the three communities, one would serve as the hub and the other two as support lodging communities. POSITIVE IMPACTS: A profitable destination resort would be developed, based on existing market research. The facility would further the goals of the Nevada State Comprehensive Outdoor Recreation Plan. The economic base of the state and the county would be diversified. NEGATIVE IMPACTS: Development of the site would disturb up to 1,274 acres of wildlife habitat and destroy 43 acres of wetlands. Habitat continuity along 1.3 miles of Galena Creek canyon would be disrupted temporarily, and 600 linear feet of the streambed and 800 linear feet of adjacent vegetation would be disturbed. The view of the area from Mt. Rose and the Mt. Rose Trail would be altered. The level of total suspended particulates would increase by 0.3 tons per day due to the use of woodburning fireplaces. During operation of the resort, carbon monoxide standards would be exceeded during worst-case peak hours. Erosion would increase by 73,300 tons of gross sediment loss and 10.08 acre-feet of net sediment loss per year. Approximately 475 acre feet would be removed from groundwater resources and 200 acre-feet from Galena Creek annually, and the quality of water in Galena Creek would decline due to urban runoff. Traffic volumes in Tahoe Basin would increase, particularly during winter weekend peaks. Construction activities would exceed local federal standards for carbon monoxide and particulates.

AN - 36401032; 1755 AB - PURPOSE: Extension of the North Douglas Highway a distance of 8.4 miles from its current terminus at Outer Point to Point Hilda on Douglas Island in the city and borough of Juneau, Alaska is proposed. The preferred plan would involve construction of a 34-foot-wide, gravel-topped, two-lane road. The road would have the same centerline as a paved road that could be constructed in the future. This would ensure that the geometrics of the road would conform to any future construction and also that the road material would be useable within a future paved-road prism. Approximately 3.5 miles of the facility would be constructed on rockfill. Other highway design features would include permanent and temporary settling ponds, armor rock bank protection, and run-off drainage diversions. The estimated cost of the project is $20.4 million. POSITIVE IMPACTS: The new facility would help the city of Juneau handle a population increase of 7,900 by 1997 by opening a new area for development of housing and related amenities. Construction of the new roadway facility would provide land access to a proposed vessel landing at Middle Point, expediting transport of workers to the developing mine at Greens Creek on Admiralty Island. NEGATIVE IMPACTS: Existence of the highway would encourage development of currently undeveloped natural lands associated with a heavily wooded shoreline. Water quality in the Peterson Creek watershed could be degraded somewhat. Traffic levels on the existing North Douglas Highway would be increased by as much as 5,300 additional vehicles per day. Hunting for Sitka blacktail deer, black bear, waterfowl, and small game would be affected by the construction and use of the highway. Noise from construction and use of the highway could impact the 22 bald eagles nesting in the vicinity. Approximately 81.3 acres of wetlands would be lost or disturbed.

Preparation date: March 9, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WILMINGTON HARBOR - NORTHEAST CAPE FEAR RIVER, WILMINGTON, NEW HANOVER AND BRUNSWICK COUNTIES, NORTH CAROLINA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1979). AN - 36396815; 1792 AB - PURPOSE: Widening and deepening portions of the Wilmington Harbor waterway system between the Fourth East Jetty Channel in the Cape Fear River to a point 750 feet above the Hilton railroad bridge on the Northeast Cape Fear River in New Hanover and Brunswick counties, North Carolina are proposed. This draft supplement to the final environmental impact statement (FEIS) of January 1980 addresses changes in the project design since the issuance of the FEIS. These changes would involve widening the harbor turning basin on the west rather than the east side, extending the 35-foot channel an additional 3,350 feet further upstream, and cancelling the plan to use federal funds to purchase in fee simple or via a conservation easement 2,800 acres of wetlands, bluffs, and buffer strips along the Northeast Cape Fear River above Wilmington for conservation purposes. The full harbor plan as currently proposed would involve widening of the Fourth East Jetty Channel by 100 feet at the existing depth of 38 feet for a distance of approximately 8,000 feet; deepening of the navigation channel from 32 feet to 35 feet over a width of 400 feet between Castle Street and the N.C. 133 Bridge; widening of the turning basin just upstream of the mouth of the Northeast Cape Fear River by 100 feet on the west side at a depth of 35 feet; and deepening of the navigation channel from 32 feet to 35 feet over a width of 300 feet from the N.C. 133 Bridge to the Hilton Railroad Bridge, located 2,600 feet upstream, and over a width of 200 feet from the Hilton Railroad Bridge to a point approximately 750 feet upstream. A total of 1.2 million cubic yards of material would be removed to create the desired waterway depths. Average annual maintenance dredging would result in the removal of 104,125 cubic yards of material. Material would be excavated via pipeline dredge. Dredged material would be dumped in upland diked disposal facilities. POSITIVE IMPACTS: Waterway improvements would result in transportation savings, expanded port activity, and increased economic diversity, employment, and property values. NEGATIVE IMPACTS: Some utility line relocations would be required. Blasting rock from the river bottom during excavation of the turning basin could place river bottom material into suspension. The new channel dimensions could have a slight impact on saltwater intrusion into the Cape Fear River system, resulting in some habitat losses. Benthic organisms would be destroyed during dredging. Approximately 0.85 acre of mixed brackish marsh fringe, located opposite the State Port, would be converted to open water as a result of the widening of the Fourth East Jetty Channel. Upland diked disposal facilities would result in damage to wildlife habitat. Historic vessels could be encountered during project implementation.

Preparation date: March 8, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SHEPARD/WARNER ROAD (RAMSEY CSAH 37/36) FROM RANDOLPH AVENUE TO EAST CBD BYPASS AND EAST CBD BYPASS FROM WARNER ROAD TO I-35E, CITY OF SAINT PAUL, RAMSEY COUNTY, MINNESOTA. AN - 36400277; 1762 AB - PURPOSE: The reconstruction and possible realignment of Shepard/Warner Road along the northern side of the Mississippi River and the construction of a new roadway (East Central Business District (CBD) Bypass) along the eastern side of downtown Saint Paul, Minnesota, are proposed. The Shepard/Warner Road improvements would extend from a point 900 feet west of Randolph Avenue to a point 500 feet east of Sibley Street, while the CBD Bypass would extend from a point 800 feet west of the Lafayette Bridge to a point 700 feet north of Pennsylvania Avenue. The project would involve some combination of the following: improvement of an existing roadway, roadway realignment, and new roadway construction. The project has been divided into six segments, including three Shepard Road segments, and three CBD Bypass segments. Shepard Road alternatives could involve the use of existing versus new alignments and at-grade versus grade separated connections to Chestnut Street. CBD Bypass alternatives could involve the use of at-grade versus grade separated connections with Warner Road, possible provision of access to the bypass from local streets, and possible connection of the bypass to I-35E. The desirable typical roadway section would feature one 12-foot and one 14-foot travel lane in each direction, with 10-foot outside shoulders, a variable width median, a ten-foot bikeway, and an eight-foot walkway. The reduced width section would feature one 16-foot and one 12-foot travel lane in each direction, with variable width shoulders, a median barrier, and an eight-foot to ten-foot combination bicycle/pedestrian path. POSITIVE IMPACTS: The reconstruction of the Shepard/Warner Road segment would replace an unsafe transportation facility, characterized by a high accident rate, with a modern safe facility. Along with the reconstructed Shepard/Warner Road, the CBD Bypass would provide regional access to the Saint Paul metro center, divert through traffic from local streets, support redevelopment of the Saint Paul Riverfront, provide better access to downtown Saint Paul, ease pedestrian and bicycle access along the river, and generally improve area aesthetics. NEGATIVE IMPACTS: The rights-of-way development for the project could result in impacts on the historic Harvest States facility and a railroad lift bridge of historic significance, relocation of railroad yards, and some filling and dewatering and floodplain encroachment.

Preparation date: March 7, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SAW MILL RIVER FLOOD CONTROL PROJECT, NEPERA PARK, YONKERS, WESTCHESTER COUNTY, NEW YORK. AN - 36396780; 1790 AB - PURPOSE: Implementation of a flood control project for the Saw Mill River basin at Nepera Park in the city of Yonkers, Westchester County, New York is proposed. Channel modifications would occur from a point approximately 1,000 feet north of the old Nepperhan Avenue bridge and continue upstream 8,400 feet to a point near the former Tompkins Avenue bridge. The trapezoidally shaped channel would have a 10-foot bottom width and 1.0 to 2.5 side slopes. In almost all reaches, channel excavations would occur within the existing channel, eliminating overbank excavation. The downstream section would tie into the existing flood control project at Yonkers. The project would also involve placement of a crushed-stone blanket in all areas not covered by riprap, replacement of the present water works weir, capping of existing Yonkers project flume walls from an average of one-half foot to two feet in height for a total distance of 1,000 feet, and the addition of 10 automatic drainage gates throughout the Yonkers project limits on presently ungated drop inlets. The total first cost of the project is estimated at $1.2 million, and the benefit-cost ratio is estimated at 3.21. POSITIVE IMPACTS: The project would reduce economic, social, and environmental losses from flooding along the Saw Mill River in the city of Yonkers and would help preserve the river's fish and wildlife habitats. NEGATIVE IMPACTS: Construction activities would temporarily degrade air, water, and visual qualities. Fisheries, benthos, and wildlife habitats would be disturbed. Flooding problems downstream of the project could be exacerbated.

Preparation date: March 4, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MORGAN COUNTY PORT ACCESS CHANNEL, MORGAN COUNTY, ALABAMA (FINAL SUPPLEMENT I TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1986 ON THE PROPOSED DEVELOPMENT AND USE OF THE MALLARD-FOX CREEK AREA IN NORTH ALABAMA). AN - 36389451; 1774 AB - PURPOSE: Excavation of a navigation channel approximately 9,100 feet in length and filling of an embayment with dredged materials in the Mallard-Fox Creek Area of North Alabama are proposed. This statement supplements the final environmental impact statement of June 1986 on development of the Mallard-Fox Creek Area. The access channel would feature a gently curving entrance and exit to accommodate 15 barge tows. The channel width would be 350 feet: 110 feet for berthing and 240 feet for navigation. Some factors affecting the channel width required for safe navigation would include alignment, velocity of currents, and definition of channel limits. Approximately 1.3 million cubic yards of material would be removed to create the channel. Borings indicate that no rock excavation would be required. Dredged material would be disposed of in a 95-acre site that includes a 20-acre embayment adjacent to the access channel and within the boundaries of the Mallard-Fox Creek Industrial Park. By enclosing this area within a dike with a top elevation of 582 feet above mean sea level (msl), this site would be able to contain all disposed materials. The embayment has a bottom elevation of 552.5 feet above msl. The project cost is estimated at $5.7 million, and the estimated benefit-cost ratio is 1.7. POSITIVE IMPACTS: Future navigation needs of Morgan County would be met by building port facilities at the proposed Mallard-Fox Creek Industrial Park. The region surrounding the new port would benefit from increased economic development and the accessibility of low-cost water transportation. The industrial park adjacent to the port would provide employment opportunities and expand the industrial base of the area. Given the scarcity of developable waterfront sites, large water-oriented industries would be drawn to the Mallard-Fox Creek Industrial Park. Benefits of $735,000 would accrue from the project during the base year. Discounted future benefits of $155,000 would provide for total average annual benefits of $890,000. NEGATIVE IMPACTS: Filling of the embayment would result in the loss of wetlands. Fish and wildlife resources would be diminished due to the loss of this habitat.

In addition, guidance is given for using SBIs to monitor potential sediment transport pathways at existing dredged material placement sites. Some of the information provided is based on results from DUCK 85 and SUPERDUCK, two large coastal processes experiments conducted during the fall of 1985 and 1986, respectively, on the outer banks of North Carolina. Seabed drifter Investigations during SUPERDUCK were directed specifically toward offshore dredged material placement applications. Other guidance is based on monitoring associated with past and ongoing projects of Corps Districts.

AN - 36388519; 1783 AB - PURPOSE: Deepening of the existing channels and approaches to Baltimore Harbor within the jurisdiction of Maryland and Virginia is proposed to allow the waterways to meet existing and prospective needs of navigation. This third supplemental information report to the final environmental impact statement (EIS) of September 1981, presents information regarding possible modifications to disposal of dredged material from the Cape Henry Channel and, possibly, the southern portion of the York Spit Channel, within the Virginia portion of the project. In addition, the supplement covers elimination of the seasonal restriction of dredging activities from project waters; the restrictions were originally enforced to protect blue crab populations, but monitoring data indicate that the restrictions were unnecessary for this purpose. The overall project, as proposed in the final EIS, would involve deepening the Cape Henry, York Spit, Rappahannock Shoal, Main Ship, and Curtis Bay channels from 42 feet to 50 and extending each of these channels to the 50-foot-deep curve; widening the Rappahannock Shoal Channel from 800 to 1,000 feet; deepening the Northwest Branch-East Channel to 49 feet over a width of 600 feet; deepening the Northwest Branch-West Channel to 40 feet over a width of 600 feet; and dredging of the turning basins at the head of the last two channels. The final EIS indicated that the material dredged from the Main Ship Channel, the Curtis Bay Channel, and the East and West channels of the Northwest Branch, all of which are located in the Maryland portion of the Bay, would be placed into the Hart-Miller Island containment facility located in the upper Chesapeake Bay. It proposed open-water disposal from the York Spit, Rappahannock Shoal, and Cape Henry channels, all of which are located in the Virginia portion of the Bay; material dredged from the Virginia channels would total 20.9 million cubic yards (mcy), 8.2 mcy, and 3.2 mcy, respectively. Under the currently proposed scheme for the Virginia Channels, material from the Cape Henry Channel and the southern portion of the York Spit Channel would be used for beach nourishment at Virginia Beach and East Ocean View. Material would most likely be dredged via hopper dredges, transported to an offshore mooring area, and pumped from the hopper dredge to the beach sites. Alternatively, the material could be pumped directly from the channel to the beach or transported via scow to the mooring area and then pumped to the beach. POSITIVE IMPACTS: Placement of up to 2.0 mcy of dredged material along the Virginia Beach shoreline between 49th Street and Rudee Inlet would increase the recreational value of Virginia Beach and reduce the threat of damage to property due to erosion. Placement of up to 600,000 cubic yards of dredged material along East Ocean View would provide similar benefits to this Norfolk recreational area. NEGATIVE IMPACTS: Dredging and disposal would destroy benthic communities temporarily and result in temporary turbidity at the dredging and disposal sites.

Preparation date: February 29, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SANDSTONE DAM AND RESERVOIR, MUNICIPAL, AGRICULTURAL, AND INDUSTRIAL WATER SUPPLY PROJECT, CARBON COUNTY, WYOMING. AN - 36402520; 1795 AB - PURPOSE: Construction of a dam and reservoir on Savery Creek in south-central Wyoming is proposed to provide for the municipal, agricultural, and industrial water supply needs of the Little Snake River basin. Savery Creek is a tributary of the Little Snake River. The dam, which would be located approximately 8.5 road miles north of the town of Savery on a constricted portion of a narrow canyon just below the mouth of Little Sandstone Creek, would impound a reservoir of approximately 52,000 acre-feet and have a surface area of 960 acres. The dam would be approximately 200 feet high and 3,100 feet long and would create a reservoir extending 7.7 miles upstream on Savery Creek, 1.9 miles upstream on Big Sandstone Creek, 2.3 miles upstream on Little Sandstone Creek, and 0.1 mile upstream on Hell Canyon Creek. The zoned earthfill dam would have a crest width of 30 feet, a crest elevation of 6,985 feet above mean sea level (msl), and a fill volume of 6.125 million cubic yards (mcy), including 1.43 mcy of impervious material, 1.19 mcy of granular material, 3.38 mcy of random fill, and 125,000 cubic yards of riprap. Borrow material for the dam would be taken from alluvial and colluvial deposits on the right side of the reservoir below high water level and the Savery and Little Sandstone creek valley bottoms. The long ridge that narrows the canyon would form the left abutment of the dam; the right abutment would be a steep slope varying from 40 degrees to 70 degrees. The project's hydraulic works would consist of an ungated chute-type spillway on the left abutment and a regulated low-level tunnel outlet in the left abutment. The upstream slope of the dam would be protected from wave erosion by riprap. The pool elevation would be 6,932 feet above msl. Normal minimum water level would be 6,800 feet above msl, while normal high water level would be 6,932 feet above msl. Dead storage would be 100 acre-feet and live storage would be 52,000 acre feet. Surcharge storage would be 21,000 acre-feet. Agricultural releases from the reservoir would be limited to providing a supplemental supply equal to 0.5 cubic feet per second (cfs) per 70 acres per year. Flows in Savery Creek below the dam would be maintained at not less than 24 cfs. The overall project would cover 4,350 acres of federal and private lands. Environmental mitigation measures would include purchase of a riparian rehabilitation easement along Savery Creek, assurance of minimum releases for Savery Creek, construction of barriers to prevent upstream movement of fish species that would impact Colorado River cutthroat trout, and maintenance of a minimum reservoir pool of 10,400 acre-feet. The dam and reservoir would lie, for the most part, on private land. Three construction seasons would be anticipated. POSITIVE IMPACTS: Reservoir waters would supply the Little Snake River basin with a firm annual yield of 20,000 acre-feet of water for industry, an average annual yield of 12,000 acre-feet of water for agriculture, and an average annual yield of 200 acre-feet of water for municipal use. Wyoming requirements of the Upper Colorado River Basin Compact would be met. Environmental mitigation measures would enhance fishery and other riparian resources within the basin. NEGATIVE IMPACTS: The impoundment would inundate 960 acres of wildlife habitat, including 397 acres of riparian cottonwood woodland, 42 acres of willow shrubland, 37 acres of alder shrubland, 339 acres of wet meadow, and 145 acres of upland vegetation. In addition, the reservoir would inundate 12 miles of flowing stream. Land used for cattle grazing and other agricultural purposes would be lost. Archaeological and historical remains not protected or recovered would be subject to inundation, erosion, and vandalism. Seasonal water level fluctuations would result in exposure of mudflats during the summer and at other dry periods. The visual aspect of the remote stream area would be altered. Discharge of sediment-free water would result in scouring effects downstream of the reservoir outlet. Total stream flow would be depleted by 13,394 acre-feet per year or approximately 4.0 to 9.2 percent.

AN - 36388359; 1689 AB - PURPOSE: Replacement of the Twin Bridges located on South Bay Boulevard in the city of Morro Bay, San Luis Obispo County, California is proposed. The Twin Bridges would be removed and replaced by one bridge, and the intersection of South Bay Boulevard and State Park Road and the approaches to the bridge would be reconstructed. The proposed replacement bridge would be constructed on new fill material located approximately 100 feet to the east of the existing bridges. The new bridge, which would be constructed of reinforced concrete, would have a minimum width of 40 feet 8 inches and a length of between 260 and 460 feet. The ultimate length of the bridge would depend on the means by which a combination of environmental, hydraulic, and cost concerns are addressed. Preliminary hydraulic calculations indicate that the bridge would most likely have to be at least 420 feet in length. Pile bents would be installed to support the new bridge, which would be designed to clear a 50-year flood and withstand a 100-year flood. Fill material would total no more than 23,500 cubic yards for a 460-foot bridge and 45,000 cubic yards for a 260-foot bridge. On completion of the new bridge, the existing structures, foundations, and roadbeds would be removed, and the habitat previously displaced would be restored as fully as possible to natural conditions. In order to achieve an anticipated mitigation requirement of two acres of land restored for each acre lost, the restored area would extend a total of 1.8 to 3.0 acres. In addition, degraded habitat adjacent to the project would be treated to restore native vegetation and wildlife habitat. The estimated cost of the project ranges between $2.5 million and $3.1 million. POSITIVE IMPACTS: Construction of new bridges would alleviate flooding and resultant road closures that presently occur when the water level of Chorro Creek rises above the existing bridges. Safe, reliable access to Los Osos and Baywood Park would be ensured. The project would also improve circulation at the intersection of South Bay Boulevard and State Park Road and allow safe pedestrian and bicycle movement across Chorro Creek. NEGATIVE IMPACTS: Rights-of-way requirements would displace 2.1 to 2.5 acres in the State Park. Approximately 0.94 to 1.49 acres of floodplain wetlands would be filled and 0.24 to 0.42 acre would be shaded.

AN - 36403375; 1687 AB - PURPOSE: Widening of 8.5 miles of Glenn Highway in the extreme northern portion of Anchorage and the southern portion of the Matanuska-Susitna Borough, Alaska is proposed. More specifically, the project would proceed from a point near the village of Ekluta to a point approximately 0.33 mile east of the Glenn Highway/Parks Highway intersection and, on the Parks Highway, to a point approximately two miles northwest of Glenn Highway. The project would involve widening the last two-lane segment of the Glenn Highway between Anchorage and the Parks Highway to a six-lane divided highway. Project design would provide for full control of access, with interchanges at the Old Glenn Highway, Knik River Access Site, Parks Highway, and the New Trunk Road. Three new driving lanes would be provided on the southbound side of the highway and an additional driving lane would be added to the northbound side of the highway over most of the length of the project. The existing bridge across the northern channel of the Knik River would be reconstructed to accommodate northbound traffic, and a new bridge would be constructed to accommodate southbound traffic crossing the river. The bridge over the middle channel of the Knik River would be eliminated as recommended by the project's hydrological study. The southern channel of the Knik River would be crossed via new bridges constructed for both northbound and southbound traffic. North of Rabbit Slough, the highway would be realigned to the east for the proposed Glenn Highway/Parks Highway interchange. New access roads connecting local roads to the proposed New Trunk Road interchange would be provided north of the Parks Highway/Glenn Highway interchange by extending Trunk Road to Nelson Road. No access would be provided to the property east of the Glenn Highway between Rabbit Slough and the Parks Highway. Cost estimates for the project range from $139.0 million to $228.0 million. POSITIVE IMPACTS: Expansion of the capacity of the highway would meet the needs of the increasing number of residential and business establishments in the Matanuska-Susitna Borough and Anchorage, areas that have been growing steadily since 1970. Commuters working in Anchorage and travelling to and from residential areas in the borough would benefit from reduced congestion. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of three to seven residences and businesses, a loss of 254 acres of wetlands, a loss of fish and wildlife habitat, and encroachment on floodplains. Noise generated by traffic on the facility would affect residential areas. Implementation of full control of access would alter access and travel patterns in the area.

Preparation date: February 16, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NEW LONDON BYPASS, USH 45, OUTAGAMIE COUNTY, WISCONSIN (PROJECT I.D. 1146-4-00). AN - 36407956; 1704 AB - PURPOSE: Construction of an 8.6 mile bypass around the city of New London in Outagamie County, Wisconsin is proposed. The bypass would begin at a point on USH 45 two miles north of New London, pass around the eastern side of New London, and rejoin USH 45 at a point three miles south of New London. Ultimately, the facility would have two 12-foot driving lanes in each direction, with 10-foot outside shoulders, 6-foot inside shoulders, a 60-foot grassed median, and flanking ditch sections. A right-of-way width of 250 feet would be required to contain this cross-section. Initially the project would be a two-lane roadway with 12-foot outside shoulders, although the earth grade for the four-lane cross-section could be developed in wetland areas and areas adjacent to river channels. Two bypass alternatives are under consideration. Following the project from its terminus south of New London, either alternative would follow existing USH 45 to within approximately 0.5 mile of the city's corporate limits before turning northeast to cross over the Fox River Valley Railroad tracks and proceed toward the New London Industrial Park. After skirting the edge of Mud Lake, the route would continue north, cross over River Road to enter the New London Industrial Park on its eastern side, and cross the Wolf River and County Trunk Highway S. At this point, the bypass would follow one of the two alternatives. Alternative (1) would continue directly north to State Trunk Highway (STH) 54 and cross over the Embarrass River to meet existing USH 45 north of New London. Alternative (2) would proceed in a northwestern direction along the edge of the Wolf River floodplain to the Embarrass River at STH 54. Interchanges and grade separation structures would be constructed to control access for either alternative. The estimated costs of construction for alternatives (1) and (2) are $7.2 million and $8.1 million, respectively. POSITIVE IMPACTS: Bypass construction would provide a connecting link for through traffic around the city of New London, eliminating the passage of regional traffic through the downtown area of the city. By the year 2013, the project, in combination with the downtown route, would handle an average daily traffic load of 18,600, a significant percentage of which would be truck traffic; approximately 50 percent of the truck traffic would be expected to use the bypass. Accident rates on the existing facility, which have been above the state average over the past five years, would decline significantly. Noise levels along the existing route would be significantly less. NEGATIVE IMPACTS: Depending on the alternative chosen, rights-of-way requirements of 219 to 222 acres of land would affect 10 to 11 farm operations, 7 to 9 residences, and 1 to 2 businesses. A mobile home located on one alternative would be acquired. The project would impact 20 to 32 acres of wetlands, and require placement of bridge support structures in the Embarrass and Wolf rivers and placement of fill in the rivers and associated marshes; as a result, habitat for sturgeon and numerous other fish species would be lost. High-value wildlife areas along the shorelines and upland areas associated with the Wolf and Embarrass rivers would be impacted. Minor, moderate, and severe noise impacts would affect eight to nine, six, and six receptors, respectively, but no violations of federal standards would occur at residential or business locations along the facility.

AN - 36405673; 1697 AB - PURPOSE: Reconstruction of 13.5 miles of MS 301 from MS 304 in Eudora, DeSoto County, Mississippi, northward to the Tennessee state line is proposed. The reconstructed road would provide two 12-foot lanes with 8-foot shoulders from Eudora to Star Landing Road, two 12-foot travel lanes with 10-foot shoulders from Star Landing Road and Church Road, four 12-foot travel lanes with 10-foot shoulders from Church Road to Goodman Road, and four 12-foot travel lanes with a 12-foot continuous left-turn lane and 5-foot shoulders, with curbs and gutters, from Goodman Road to the Tennessee state line. Short sections of the roadway would be realigned to correct severe curvature problems. More specifically, the preferred alternative would generally follow the existing road alignment to a point approximately 2.5 miles north of Eudora, provide a realignnment at that point to ease sharp horizontal curves, and continue to follow the present alignment to the state line. Rights-of-way requirements between Eudora and Goodman Road would have a minimum width of 150 feet, while the rights-of-way width between Goodman Road and the Tennessee state line would be 120 feet. Design speed for the facility would be 55 miles per hour. POSITIVE IMPACTS: Reconstruction of the facility would improve the functioning of the transportation network for local and through traffic. The facility would also provide fast and efficient transportation and a more efficient system for emergency vehicles and would generally improve safety conditions for the transportation system. New land areas would be open for commercial development, subdivisions, and industrial development. The visual aspect of the road and the view from the road would be enhanced by the use of modern design features. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 17 families and 1 farm operation and the loss of 109.6 acres of prime farmland. Noise levels along the route would increase by two decibels on the A-weighted scale for residents along the reconstructed highway.

AN - 78158546; 3355134 AB - Toluene and m-xylene were rapidly mineralized in an anaerobic laboratory aquifer column operated under continuous-flow conditions with nitrate as an electron acceptor. The oxidation of toluene and m-xylene was coupled with the reduction of nitrate, and mineralization was confirmed by trapping 14CO2 evolved from 14C-ring-labeled substrates. Substrate degradation also took place when nitrous oxide replaced nitrate as an electron acceptor, but decomposition was inhibited in the presence of molecular oxygen or after the substitution of nitrate by nitrite. The m-xylene-adapted microorganisms in the aquifer column degraded toluene, benzaldehyde, benzoate, m-toluylaldehyde, m-toluate, m-cresol, p-cresol, and p-hydroxybenzoate but were unable to metabolize benzene, naphthalene, methylcyclohexane, and 1,3-dimethylcyclohexane. Isotope-dilution experiments suggested benzoate as an intermediate formed during anaerobic toluene metabolism.

This data can be found on a variety of computer storage devices such as tapes, disks, and floppies. Analysis of this data is challenging because the concentration of chemical constituents in water may vary both spatially and temporally. A variety of techniques, including analytical and statistical, is necessary for analysis. As a result, to be useful for water quality analysis, computer software must be powerful, flexible, and capable of producing high quality graphics. Within the Corps of Engineers, water quality data has been analyzed by a variety of people with different hardware (micros to mainframes) and software (LOTUS, D-Base, SAS, SPSS, etc.). As a result, many of the programs written are incompatible with other users' programs, and there is a great deal of duplication of effort. In this paper, I have reviewed the capabilities of the statistical Analysis System (SAS) for water quality analysis and its potential application as a standard system for the Corps of Engineers.

The test was designed to determine if, through the use of a hydraulic dredge, dredging fine-grained estuarine sediments with discharge into dump scows, it would be possible to increase the sediment content of the scows by continued dredging and discharge past the point of scow overflow. Additionally, the test design also provided for an analysis of the environmental impacts associated with such overflow. The continued use or establishment of new open water sites in estuarine waters for the disposal of dredged material is undergoing increased opposition. In many cases there are no suitable alternative sites available within feasible hydraulic pipeline distances. In those cases where open water disposal is excluded from use and there are no suitable upland sites available, the transport of dredged material via scows to more remote sites is a likely alternative. This type of dredged material transport is expensive and the costs increase substantially with the distance from the dredging site to the disposal area. The increasing number of approved ocean disposal sites in recent years reflects the scarcity of suitable upland areas and the trend to abandon the traditional open water disposal.

George Dam AN - 20258629; 7362304 AB - The Walter F. George (WFG) Lake is formed along the Chattahoochee River by the WFG Lock and Dam (L&D), which is located near Fort Gaines, Georgia. The impounding structure consists of a concrete dam, a fourteen-gated spillway and single lift lock. The WFG Lock is the second highest lift east of the Mississippi River. The WFG Powerhouse with four generating units is located on the opposite bank from the lock. The lake is 121 km (75 mi) from the mouth of the river, has a surface area of 18 292 ha (45 181 ac), and is 28.3 m (93.0 ft) at the deepest point. Normal pool elevation is 57.9 m (190.0 ft) National Geodetic Vertical Datum (NGVD). Authorized primarily for navigation and hydroelectric power generation, associated purposes include flood control, streamflow regulation to provide a nine-foot navigation channel, outdoor recreation and fish and wildlife conservation. The WFG Powerhouse is operated as a peaking facility. Characteristically, hydroelectric power is generated 3 to 6 hours (hr) daily, Monday through Friday. The turbine intake gates are located on the bottom of the lake and are approximately 7.5 m (24.8 ft) high. Approximately 47 river km (29 river mi) downstream of WFG L&D is the George W. Andrews (GWA) L&D. This structure consists of a concrete dam with a fixed spillway and a single lift lock. The GWA L&D is a single purpose navigation project intended only to provide sufficient depth for authorized navigation. The lake created by GWA L&D has a surface area of 623 ha (1 540 ac).

Sediment quality issues must be adequately addressed in order for the Corps to receive water quality certifications from State environmental quality agencies and disposal site approvals from the U.S. Environmental Protection Agency (EPA). Evaluations are conducted for a wide range of sediment types and dredging quantities with potential impacts ranging from minimal to severe. An evaluation can range from an available information review to physical characterizations, chemical analyses, or comprehensive bioassay/bioaccumulation tests. A total of 15 - 20 million cubic yards of sediments are dredged annually from 32 authorized projects in the Portland District navigation program (Figure 1). Most materials are clean sands with little toxicity potential. However, several projects contain some slightly to moderately contaminated silt/clay sediments. Also, high levels of public environmental awareness in the Pacific Northwest have resulted in concern with contamination levels that would be considered low to moderate by national perspectives. In response to these concerns, we have developed a tiered sediment quality evaluation framework that allows for more consistent design of project-specific testing programs. Its main objective is to provide a method for more efficiently maintaining statutory compliance while conducting Portland District's dredging program. The framework minimizes tendencies for excessive testing of low-risk projects while justifying more attention to higher-risk actions. This has resulted in more efficiently completing required evaluations, has reduced costs, and is making data available to Corps managers and resource agencies in a more timely manner.

Hurricane Gloria passed directly over the Central Long Island Sound disposal site with sustained winds of 130-140 km/h (80-90 mph). Bottom currents measured at a station at the New London disposal site, approximately 65 km east of the storm track, increased approximately 10 cm/sec over the ambient maximum of 35 cm/sec, and bottom wave pressures were significantly perturbed during the height of the storm. Near-bottom suspended sediment loads at the New London station were 2 mg/1 before the storm and increased to 16 mg/1 in response to the effects of wind-induced waves during the storm. Bathymetry and REM0TS surveys of the disposal mounds at Western and Central Long Island Sound disposal sites were conducted in late October 1985, and the results were compared to surveys from earlier in the year. In addition, the New London disposal site was surveyed in July 1986. At the Central Long Island Sound disposal site, only the mound designated CS-1 (with a silt cap) had a detectable volume change. The volume change observed at this mound may have occurred because of both erosion and consolidation. At the Western Long Island Sound and New London disposal sites, no differences in volume or minimum depth were observed at the sites' mounds. Results of this study provide increased confidence in the stability of dredged material disposal mounds at similar and greater depths and the caps used to isolate more contaminated material.

AN - 36403861; 2119 AB - PURPOSE: Relocation of 7.6 miles of U.S. 411 to a fully access-controlled highway in Bartow County, Georgia is proposed. The newly located four-lane facility would begin at the State Route (S.R.) 20 interchange with U.S. 411 on the west and extend to Interstate 75 (I-75) at a point approximately one mile south of the existing U.S. 411 interchange with I-75 on the east. More specifically, the new highway would proceed in a northeasterly direction from U.S. 41, bridging over Mac Johnson Road, Rudy York Road, and Peeples Valley Road. It then would continue in an easterly direction north of Keith Road, bridging over Old Grassdale Road, which would be realigned, continue in a southeasterly direction across the Georgia Power Transmission Lines, turning to the east to bridge over the CSX (Seaboard) railroad and rail yard and U.S. 411/S.R. 61, and tying into I-75 one mile south of the existing I-75/U.S. 411 interchange. Kellogg Circle would be partially displaced and either closed on the south end or provided with a new connection to U.S. 411/S.R. 61 just north of the proposed project. Keith Road would be relocated to have a new connection with Peeples Valley Road just to the south of its existing connection. The typical highway section would consist of two lanes in each direction, separated by a 30-foot grass median with a double-faced guardrail, and 12-foot outside shoulders, within a minimum rights-of-way of 400 feet. Local access would be maintained primarily through highway separation structures. The project would include reconstruction of the existing U.S. 411/S.R. 20 interchange and a new full directional interchange at I-75. The full directional interchange at I-75 would include a collector distributor with existing S.R. 61. The interchange improvements at U.S. 41 and I-75 are designed to be compatible with the ultimate future design that is proposed in the event the outer perimeter transportation plan is effected. The estimated costs of rights-of-way acquisition and construction of the project are $10.5 million and $33.8 million, respectively. POSITIVE IMPACTS: Reconstruction of U.S. 411 on new alignment would remove much of the through traffic congesting local streets between Rome and I-75 along the heavily travelled U.S. 41 and S.R. 20 corridors. Travel times would be decreased and fuel efficiency enhanced for motorists using the new facility to travel to and from points within the U.S. 411 corridor. Air quality would improve due to decreases in traffic congestion. Access to the facility via S.R. 20 and the I-75 interchange would be improved. NEGATIVE IMPACTS: Rights-of-way requirements would result in the displacement of 19 residential units and 20 mobile homes. Noise impacts would affect 11 sensitive receptors. The proposed alignment would cross the headwaters of Nancy Creek and Pettit Creek. Some local road closures and relocations would be necessary to maintain full access control for the facility.

AN - 36389341; 1703 AB - PURPOSE: Construction of a new 4.7-mile controlled-access urban arterial and a Chippewa River crossing in the northern part of the city of Eau Claire, Eau Claire County, Wisconsin is proposed. The four-lane arterial, to be known as the North Corridor Arterial, would extend from US 12 to US 53. Between US 12 and the Chippewa River, the connector would consist of a typical urban arterial section. West of the river, where land uses are rural, a modified urban section would be provided. The modified urban section would consist of two 12-foot lanes in each direction, a grass median, 10-foot outside shoulders, and a ditch section on each side; typical rights-of-way would be 180 feet wide. The project would include an at-grade intersection at Jeffers Road and Gessner Road; a T-type intersection on the north side of the roadway at one location between the Chippewa River and Riverview Drive and at a new connector to Marquette Street just south of North High School; cul-de-sacs at the existing Welsh Drive and Claire Street crossings and on Marquette Street just west of the high school track and just west of the probable US 53 interchange; and grade separations at Starr Avenue, Western Avenue, and the Chicago and Northwestern Railroad tracks. The estimated cost of the project is $24.3 million, including $14.3 million for roadway construction, $6.0 million for bridge construction, $1.8 million for acquisition of rights-of-way, and $2.2 million for related activities and contingencies. POSITIVE IMPACTS: Indirect traffic routes through the downtown area would be replaced by a direct route linking the northeast and northwest parts of the city. The accident rate along the existing, indirect route would decrease significantly as traffic is diverted to the connector. A new river crossing would be provided for the Chippewa River, and access to the Eau Claire County Airport would be improved. A more direct link would be provided connecting DeLong Junior High School and North High School. All areas recommended for future development would be served, and travel times and distances and vehicle fuel consumption would decline. NEGATIVE IMPACTS: Rights-of-way development would result in conversion of 103 acres of land and displacement of 3 businesses, 43 residential units, and 35 residential properties. The project would result in the loss of 16.5 acres of woodland and encroach on 5.2 acres of floodplain.

AN - 36405516; 1696 AB - PURPOSE: Extension of Warren Road a distance of 1.3 miles from its present terminus at Maryland Route 45 (York Road) to Interstate 83 (I-83) (the Harrisburg Expressway) in Cockeysville, Baltimore County, Maryland is proposed. Projected phased construction of the highway would extend from 1988 to 1992. Under the preferred alternative, Warren Road would be widened for a distance of 800 feet from York Road to York Avenue. Between the intersections at York and Beaver Dam roads, the new Warren Road would be designed for a vehicle speed of 50 miles per hour (mph) and would consist of a curb-and-gutter, five-lane highway. West of Beaver Dam Road, the facility would transition to an open cross-section four-lane divided highway with a 34-foot-wide median and graded shoulders; design speed for the open section would be 50 mph to 60 mph. A partial interchange would provide access to Warren Road from I-83. Access to I-83 from Warren Road would be provided via the existing Shawan Road access ramp; a sign would direct motorists to the ramp from the intersection of Warren Road and Beaver Dam Road. Estimated costs of construction and rights-of-way acquisition are $14.9 million and $5.5 million, respectively. POSITIVE IMPACTS: Extension of Warren Road and the I-83 interchange would relieve traffic congestion along York Road and on Padonia and Shawan roads. The extended road would draw traffic off York Road, relieving congestion on that arterial. The extension would also provide an alternative route to I-83 and would relieve rush hour congestion on I-83 in the vicinity of Warren Road. NEGATIVE IMPACTS: Properties affected by the highway would include up to 1 farm, 5 residences, 20 commercial establishments, and 1 public facility. The project would displace 51.3 to 78.2 acres for rights-of-way purposes; displacements would include 0.06 acres of agricultural land, 44.0 to 70.3 acres of commercial land, 7.5 acres of public administrative land, 0.1 acre of residential land, 7.9 acres of permitted mining land, 3.5 to 4.2 acres of wetland, 5.3 to 7.0 acres of public 100-year floodplain, and 21.5 to 45.8 acres of woodland. Noise generated by traffic along the facility would exceed federal standards at two locations. The facility would traverse five to eight streams.

Preparation date: January 22, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LAKE WICHITA, HOLLIDAY CREEK, WICHITA FALLS, TEXAS: McGRATH CREEK FLOOD CONTROL REPORT (DRAFT SUPPLEMENT II TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1981). AN - 36401658; 1712 AB - PURPOSE: Implementation of flood control measures for the McGrath Creek watershed in Wichita Falls, Texas is proposed. This statement supplements the final environmental impact statement on flood control measures for areas affected by Lake Wichita and Holliday Creek. The 5.6-square-mile McGrath Creek watershed lies in a highly urbanized area within the city limits of Wichita Falls. McGrath Creek is a tributary of Holliday Creek which, in turn, flows into the Wichita River. The preferred alternative would involve construction of a 110-foot-wide spillway at Sikes Lake and a 3,600-foot-long rectangular, concrete-lined channel with a 35-foot bottom width from the new spillway to a drop structure at the mouth of McGrath Creek. The new spillway, which would be placed 700 feet north of the existing spillway, would have a crest at elevation 960 feet, a crest width of 110 feet, and a length of 187.5 feet. The spillway would drop from elevation 960 feet to the channel invert at elevation 946.1 feet. The existing spillway would be removed and the area filled with material excavated from McGrath Creek to conform with the embankment. The 3,600-foot concrete-lined channel would generally follow the existing creek alignment. The estimated cost of the selected plan is $8.5 million in April 1985 dollars. The benefit-cost ratio is estimated at 1.7 to 1.0. POSITIVE IMPACTS: Plan implementation would provide protection against a 100-year-frequency flood to properties along McGrath Creek between Sikes Lake and the confluence of the creek with Holliday Creek. Flood damages to properties immediately upstream of Sikes Lake would also be reduced. Creation of a concrete channel would reduce bank erosion and sedimentation. NEGATIVE IMPACTS: Approximately 3,900 feet of aquatic habitat along the creek would be destroyed by channelization and 3.9 acres of associated terrestrial habitat would also be lost. Removal of riparian vegetation would reduce stream bank shading and increase water temperatures. Habitat diversity within the creek would be limited to communities capable of colonizing the monotypic habitat of the cement channel. The velocity of flood discharges to the Wichita River would be increased.

AN - 36406598; 1709 AB - PURPOSE: Protection of the banks of the Sacramento River between river mile (RM) 176L/184R and RM 194 in Glenn and Butte counties, California is proposed. A total of 835,000 linear feet of bank protection has been authorized. This third supplement to the final environmental impact statement (FEIS) on the Sacramento River Bank Protection Project (SRBPP) describes the impacts of bank protection along 13,700 linear feet of the Sacramento River, responds to questions and concerns raised in response to Draft Supplement III, and describes mitigation measures to be implemented to reduce impacts to a level of insignificance. The preferred alternative would involve construction of rock revetment (riprap) at five sites. Construction at two of the sites would be deferred for consideration of palisades as agreed upon during consultation with the Fish and Wildlife Service's Endangered Species Office. The sites planned for protection would include an 1,800-foot site consisting of an upstream extension of an existing site at RM 188.5R; a 5,500-foot site at RM 190.7L; a 4,500-foot site at RM 191.6R; a 1,200-foot site at RM 192.4L, consisting of a downstream extension of an existing site; and a 670-foot site at RM 187.2L. At each site, a strip of land approximately 50 feet in width would be cleared. Approximately 30 feet of the width would provide an area for temporary construction and maintenance access easements. The remainder of the area would be excavated to create the desired slope. The palisade system would probably consist of a series of parallel jetties constructed perpendicular to the bank. At an existing palisade site at Woodson Bridge, the jetties consist of 40- to 45-foot 10-inch-diameter steel piles driven to a minimum penetration of 18 feet and spaced at 40-foot centers. High-strength nylon was strung between the piles in manufactured panels 15.5 feet wide and 12.5 feet high. Fence jetties generally extend out into the river a minimum of 32 feet and a maximum of 96 feet. Mitigation measures related to losses of terrestrial and fishery habitat would be investigated under a research and development plan designed to quantify impacts and means of dealing with them. POSITIVE IMPACTS: Implementation of this phase of the SRBPP would assist in ensuring the integrity of the Sacramento River Flood Control Project levee system. The required flow split between the river and the Butte Basin overflow area would be maintained, and flows in excess of project design capacity would be prevented from entering the leveed reach of the river. Sufficient flood flows would be diverted into the Butte Basin overflow area. NEGATIVE IMPACTS: Approximately 12 acres of riparian vegetation would be removed during construction, and structures would prevent formation of approximately 81 acres of riparian vegetation over a 50-year period. The continued existence of the endangered valley elderberry longhorn beetle could be jeopardized, and other species on federal and state endangered species lists could be affected. Available juvenile salmon rearing habitat would be reduced through conversion of naturally eroding banks to rock riprap areas. Habitat for swallow nesting would be lost. The visual intrusion of project structures would impair the eligibility of the river for designation as wild and scenic. One cultural resource site of no great significance, located near the Monroeville Bend, would be affected.

Preparation date: January 12, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SACRAMENTO RIVER BANK PROTECTION PROJECT (BUTTE BASIN REACH), CALIFORNIA (FINAL ENVIRONMENTAL IMPACT REPORT AND FINAL SUPPLEMENT IV TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1973). AN - 36403138; 1708 AB - PURPOSE: Protection of the Sacramento River Bank Protection Project (SRBPP) levees from erosion along the Sacramento River between river miles (RM) 0 and 194, including the Delta sloughs of the Sacramento River, the Yolo Bypass, the Colusa Basin Drainage Canal, and the lower Feather River, in Solano, Sacramento, Yolo, Sutter, Solusa, Glenn, and Butte counties, California is proposed. A total of 835,000 linear feet of bank protection has been authorized. This final fourth supplement to the final environmental impact statement (FEIS) describes the impacts of the remaining congressionally authorized bank protection of up to 132,000 linear feet along the Sacramento River system as far north as Chico Landing. A method to implement the programmatic analysis at future work sites is described, and outstanding impact mitigation requirements are established. Bank protection work may occur at more than 100 tentatively identified sites during the the 1988-1991 period, although actual construction sites would not be finalized until the winter prior to construction. Selection of an appropriate bank protection method for an erosion site would be site-specific, with final decisions depending on various considerations. Bank protection methods would fall into one of the following general categories: (1) armoring with riprap to enable banks to withstand erosive forces of flows or waves, and (2) flow modification to direct erosive forces away from the bank. Several riprap configurations would be used. Flow modification methods would be studied in upstream areas. The preferred alternative would result in the use of various configurations and heights of riprap. Estimated costs of the project range from $20 million to $25 million; annual maintenance costs are estimated at $40,000 to $50,000. POSITIVE IMPACTS: Under all scenarios, the proposed program would increase the proportion of the Sacramento River bank protected under the SRBPP from 35 percent to 41 percent, although bank protection would be implemented at sites with widely differing levels of bank protection. Reliability would be optimized by using methods requiring the least maintenance. NEGATIVE IMPACTS: Project activities could result in a loss of 72 percent of woody riparian habitat, 11 miles of shaded aquatic habitat, and any special-status plant, bird, and insect communities found at work sites. Chinook salmon rearing habitat would also be displaced at most work sites.

Preparation date: January 7, 1988 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED UNCONFINED, OPEN-WATER DISPOSAL SITES FOR DREDGED MATERIAL, PHASE I AREA, CENTRAL PUGET SOUND, WASHINGTON. AN - 36389270; 1713 AB - PURPOSE: Designation of ocean dumping sites for disposal of material dredged from the Phase I study area of the Puget Sound Dredged Disposal Analysis of Washington State is proposed. The Phase I area consists of the central portion of Puget Sound. Historically, material dredged from the sound's waterways was often used as fill for associated harbor and terminal development. Although this practice has continued, public concern about the filling of wetlands, tidal areas, and marshes has resulted in a curtailment of such activity. Since 1970, unconfined, open-water dumping has been the preferred means of disposal. The currently proposed plan would involve the use of three public multiuser unconfined, open-water disposal sites that would partially satisfy the future dredged material disposal needs of the Phase I area. Because the Phase I area contains the major urban and industrialized centers of development, where significant waste discharges have occurred, only approximately 60 percent of this area's future dredged material would be acceptable for unconfined, open-water disposal. An unconfined, open-water disposal site would be designated in each of the Tacoma, Seattle, and Everett urban embayments of Commencement Bay, Elliott Bay, and Port Gardner, respectively. The sites, while varying in size due to bathymetry, average approximately 350 acres in potential bottom impact area. Each site has a 900-foot radius, 58-acre surface disposal zone within which all suitable dredged materials would be released. The preferred sites would be located in areas relatively free of important biological resources and human use activities. The center of the Commencement Bay disposal zone would lie approximately one mile west of Browns Point in water approximately 530 feet deep. In Elliott Bay, the center of the disposal zone would lie approximately 0.75 mile north of Harbor Island in water approximately 265 feet deep. The center of the Port Gardner zone would lie approximately 2.25 miles southeast of Gedney Island in water approximately 420 feet deep. Site management plans and material evaluation procedures, related to the potential for long-term chemical effects that could be allowed on biological resources due to disposal, would be implemented. During the 1985-2000 period, the Commencement Bay, Elliott Bay, and Port Gardner disposal facilities would receive 1.3 to 3.8 million cubic yards (MCYs), 3.1 to 6.2 MCYs, and 2.2 to 4.9 MCYs, respectively. Material designated for confined disposal during the same period would amount to 4,516 to 12,724 MCYs. Depending on the amounts of material designated for confined and unconfined disposal, estimated costs of testing, dredging and disposal, and monitoring range from $150.1 million to $267.7 million. POSITIVE IMPACTS: Provision of a permanent disposal program for materials dredged from the Puget Sound waterways would support commerce on the waterways, which provide access to the Port of Seattle and Port of Tacoma. The ports' activities support 70,000 jobs and generate an annual business volume of nearly $4.0 billion. Site management plans and material evaluation procedures would prevent release of toxic materials into the sound. NEGATIVE IMPACTS: Localized reductions in air quality could occur in the vicinity of the preferred open-water disposal sites due to exhaust emissions from disposal equipment. Temporary reductions in water quality at the sites would result from release of sediments into the water column. Benthic habitat at the disposal sites would be smothered periodically. Use of the disposal sites would result in periodic disruption of navigation.

It was assumed that the reader has knowledge of the basic input requirements. The computer procedure for delineating a floodway includes: (a) the development of water surface profiles under natural conditions (i.e., prior to encroachment), and (b) the delineation of a designated floodway that meets certain requirements. The procedure in the HEC-2 encroachment routines allows a program user to make the preliminary estimate of a designated floodway in one operation of the program. Additional computer runs may be made to improve the acceptability of the floodway. The computerized procedure was discussed and illustrated in an example problem. Appendices contain a hand calculation example to illustrate the procedure, and first and second trials of a simple problem using the HEC-2 program. The User's Manual, available from the Hydrologic Engineering Center, provides the input specifications. JF - Training Documents.

Bone development of fish from two contaminated sites in Rocky Fork and from four reference sites was examined to evaluate variability among reference sites, and to determine if the clean-water headwater site on Rocky Fork was a suitable reference site for the two downstream contaminated sites. Collagen composition, density, strength, and energy-absorbing capacity of bone were significantly higher in fish from the headwater site on Clear Fork (upstream from an impoundment) than in fish at the other three reference sites. In bones of creek chub from sites in Rocky Fork where the water contained high total concentrations of chromium, copper, iron, nickel and zinc, the collagen content of bone was lower but density and strength were higher than in bone of fish from the reference site. Some fish also had deformed vertebrae in the caudal peduncle region of the spinal column, which is a condition characteristic of neuromuscular overload of vertebrae. The high concentrations of chromium and zinc in fish from the contaminated sites probably interfered with collagen metabolism and altered the density and mechanical properties of bone. Creek chub at the contaminated sites seem to be tolerant of heavy metal contamination and may be adapting physiologically to the chronic metal stress in their environment.

Conflicts among environmentalists, developers, and government agencies are well known; they involve planning, constructing, operating, and regulating water resources projects. Two Section 404 permit cases are compared. One in 1980, involves issuing a general permit (GP) for wetland fill on Sanibel Island, Florida. The other, in 1987, involves issuing a GP for hydrocarbon exploration drilling throughout Louisiana and Mississippi. Generally, permits are granted on a case-by-case basis, but Corps district engineers may also issue GPs for activities that produce no negative cumulative impacts. In these cases the Corps adopted a revolutionary approach to GPs. Rather than writing the permit in house, the Corps suggested that the parties who conflict over permit applications get together and write the technical specifications for a GP. The Corps told environmentalists, citizens, contractors, industrialists, developers, and representatives of government agencies if they agree to the specifications of a permit within the broad legal constraints of the 404 law, the Corps would confirm the agreement and call it a GP. The price of such an agreement is consensus among the parties normally in conflict over permit applications. In this way the Corps becomes the facilitator of consensus among interested parties by using its authority. The Sanibel permit operated unchallenged for five years, the legal life of such a permit. The Mississippi/Louisiana permit was just issued. These cases both confirm and question some propositions emanating from the fields of negotiating and bargaining.

A 30-foot-diameter cell will be constructed of steel sheet piling with sand fill and a concrete cap. Approximately 1,780 cubic yards of rock berm will be deposited on the river bottom around the cell to stabilize the structure. Short-term adverse impacts due to construction and placement of the rock berm are expected to be offset by long-term benefits resulting from the introduction of a biologically productive rockpile at the construction site. No adverse impacts to endangered species or other environmental concerns are anticipated. The study was initiated in the fall of 1985, and an environmental assessment was prepared and released for public review in March 1986. New information received during the review period concerning the possible presence of mussel beds and the endangered species Lampsilis higginsi caused the Fish and Wildlife Service to request that the Rock Island District conduct a biological assessment. Results of the biological assessment and updated project design information are incorporated in this revised environmental assessment.

AN - 15266542; 2027943 AB - Construction of the Lake Pontchartrain, Louisiana, and vicinity hurricane protection project caused habitat loss in the Pontchartrain Basin. There would be an annualized loss of 854 acres of brackish/saline marsh, 108 acres of fresh/intermediate marsh, 233 acres of marsh pond, and 134 acres of forested wetlands (a total of 1,329 acres). There would also be a loss of 2,610 Average Annual Habitat Units (AAHU's) for seven wildlife species. Sixteen mitigation plans were considered. Two plans were selected for detailed study. Both plans mitigated over 80% of the wildlife acreage loss and over 95% of the AAHU's lost. Plan M protects the 6.25-mile shoreline of the Manchac Wildlife Management Area (WMA) with a non-continuous two-foot high rock dike. The 20-foot per year loss of shoreline would be eliminated and 1,200 average annual acres of wetlands would be preserved, compared to the without-project condition. Plan O would protect approximately 5 miles of the Manchac WMA from shoreline erosion, thus preserving 1,100 average annual acres of wetlands.

The dredged material normally settled as a slurry by zone settling, forming a clarified supernatant in the disposal area. Settling tests were conducted on sediments from Mobile harbour, Black Rock harbour and Yellow creek using the modified column test. The effect of initial supernatant SS concentration, depth of averaging on concentration remaining and initial slurry concentration on sediment settling are summarized. The settling behaviour of fine particles initially remaining in the supernatant was determined. Procedures were developed to predict the effluent concentration as a function of retention time and other relevant operating conditions. Based on comparisons of column predictions and measured field data, settling efficiency factors ranging from 1.5 to 2.5 conservatively predicted effluent SS concentration.

Prediction of effluent quality based on total contaminant concentrations was based on both modified elutriate test results and estimates of total suspended solids concentrations in the effluent determined by settling column tests and an estimated resuspension factor.

Tides, winds and river discharge were all important factors controlling transport and circulation. North winds, dominant during winter frontal passages, caused a net export of water. In April, during high river flow, southeasterly winds created an opposing hydraulic pressure gradient diverting river flow into Fourleague bay and inundating adjacent marshes. Tidal-dominated circulation occurred during calm periods prevalent in the summer.

Significant amounts of lipophilic detergent residues accumulated in the sludge including linear benzene sulphonates and nonylphenol (formed by decomposition of ethoxylate detergent ingredients). The concentrations of these and related metabolites were monitored throughout the sewage and sludge treatment process. The formation of breakdown products at various stages of activated sludge treatment and subsequent anaerobic sludge digestion is discussed. Results demonstrated the accumulation of significant amounts (several mg per kg of sludge solids) of lipophilic detergent residues, although the amounts of nonylphenol had diminished since 1986 following the introduction of a ban on the use of nonylphenol ethoxylates in household detergents. Estimated soil loads of these compounds following the agricultural disposal of sludge were calculated. JF - Sewage Sludge Treatment and Use: New Developments.

AN - 36388887; 1659 AB - PURPOSE: Construction of 21,460 feet of levees is planned on the north and east boundaries of Halstead, Harvey County, Kansas, along with clearing, snagging, and widening 3.5 miles of the channel of the Little Arkansas River to a 60-foot bottom width. This supplement to the final environmental impact statement of October 1978 updates the final statement to include findings of additional studies regarding mitigation of fish and wildlife losses caused by the project and addressing the need for additional access points to the Little Arkansas River. The project would consist of a levee on the north and east sides of Halstead. The river channel would be enlarged to a bottom width of 60 feet for a length of four miles. Approximately 500 feet of channel would be realigned in the vicinity of the Warkentin Homestead. Three interior ponding areas, with an overall surface area of 19 acres, would be created. Easements would be purchased on 298.5 acres of land, including 62.1 acres dedicated to wildlife habitat. Mitigation features would include 11 rock-lined pool-riffle areas, a pilot channel connecting the pool areas, planting of vegetation to create wildlife habitat, management of project lands for enhancement of fish and wildlife habitat, preservation of selected timber areas along the stream banks, revegetation of levee slopes and other disturbed areas, planting of water-tolerant trees around interior ponding areas and between the levee and the streambed, designation and management of interior ponding areas for wildlife habitat management, purchase of restrictive easements on project lands between the interior rights-of-way and the streambed, and provision of walk-in access for fishing. POSITIVE IMPACTS: Land-use potential would be enhanced in lands protected by the levee and the improved drainage system. The productivity of the whole area would benefit from increased agricultural production, increased wholesale and retail trade, and an increased tax base. Flood control would lessen the threat of flood disasters, eliminate epidemics and other aftereffects of flooding, prevent interruption of highway and rail traffic, and provide opportunities for park development. NEGATIVE IMPACTS: Levee construction would disrupt the ecosystem. Channel realignment and excess siltation during construction could destroy aquatic habitat and cause fish to leave the area. The changed plan would require 298.5 acres of land, of which 75 percent is farmland, 7 percent is floodplain forest, 5 percent is native grasslands, and 2 percent is upland forest. A ballpark and recreation park would be encroached upon, and one family would be relocated.

Preparation date: December 31, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COQUILLE REROUTE SECTION, COOS BAY-ROSEBURG HIGHWAY (HIGHWAY 42), COOS COUNTY, OREGON. AN - 36406976; 1651 AB - PURPOSE: Widening and realignment of the Coos Bay-Roseburg Highway (Oregon Route 42) through the city of Coquille in Coos County, Oregon is proposed. Two alternatives are under consideration. Regardless of the alternative chosen, the facility would feature four travel lanes, paved shoulders, and a paved median, with facilities for left-turn storage. Alternative A primarily follows the existing route of Highway 42 for 2.4 miles through Coquille, although a seven-block section would undergo realignment. More specifically, Alternative A would follow the existing Alignment from Cedar Point Road to 10th Street then shift one block to the east to use Adams Street (rather than Central Boulevard and other downtown streets) as the through route. Adams Street would be developed into a four-lane thoroughfare from 10th Street to the project terminus at a point just south of Main Street. Under Alternative A, the roadway would be widened on one side at a time to prevent extensive disruption of traffic. Alternative B would establish a new, shorter route, extending approximately 1.5 miles, across the Coquille River /Cunninghan Creek floodplain. Beginning at a point approximately 1,100 feet east of Cedar Point Road, Alternative B would veer southeast to parallel the railroad tracks to a junction with Main Street at the north approach to the new Coquille River Bridge. From that point, the alignment of Alternative B would follow Main Street east to Adams Street and merge with the existing Coos Bay-Roseburg Highhway. Alternative B would be built across portions of two log ponds and the Cunningham Creek/Coquille River floodplain on an earth and rock fill approximately 15 feet high and 1 mile long. Alternative B Also would call for a design option for connecting the Sanford Heights neighborhood to the new highway by way of Myrtle Street. Estimated construction and rights-of-way costs for Alternative A are $4.9 million and $2.6 million, respectively. Respective construction and rights-of-way costs for Alternative B are $6.1 million to $6.2 million and $1.2 million to $1.3 million, respectively. POSITIVE IMPACTS: Rerouting of the highway segment would reduce traffic congestion currently affecting the highway and improve traffic safety along the route. A more direct route would be provided through the downtown area to replace the narrow roadway, characterized by right-angle turns, that currently serves the corridor. NEGATIVE IMPACTS: Rights-of-way requirements for alternative A would involve acquisition of 13 acres of additional land, displacing 20 homes and 17 businesses, and removing 0.1 acre from a two-acre public recreational field at Coquille Valley Middle School. Construction of Alternative B would require displacement of 10 businesses and one to three homes and placement of fill within 17 acres of floodplain and wetland areas characterized by weak underlying soils. Alternative A would require 100,000 cubic yards of fill and 100,000 tons of rock and paving mix, while Alternative B would require 300,000 cubic yards of fill and 90,000 tons of rock and paving mix. Significant noise impacts would affect 57 receptors under Alternative A and 36 receptors under Alternative B.

Two new and significant tools are the widespread availability of spaceborne multi-spectral remote sensing systems, and the development of more sophisticated and less expensive microcomputer workstations for both image processing and spatial data (GIS) analyses. This paper describes an evaluation of emerging remote sensing and spatial data capabilities and applications performed for the Corps of Engineers Hydrologic Engineering Center at Davis, California It first surveys recent and planned spaceborne remote sensing systems providing data relevant to the hydrologic community. Next, integrated digital microcomputers for applied hydrologic analyses are reviewed. Finally, the interaction of these capabilities is examined in the context of specific hydrologic engineering and planning tasks, ranging from real-time flood forecasting, to urban watershed modeling, to snow cover, evaporation, and soil moisture estimation.

The sturgeon aggregate in the river channel during daylight hours, especially in the area between Trenton and Florence, N.J. (river km 211.8 to 198.8). Occurrence in the river downstream of Florence appears to be restricted by poor water quality during summer months. Sturgeon were present in the study area throughout the year, but largest numbers were collected from May through November. No spawning was observed during this study, but presence of males with milt suggests that spawning possibly occurs in the Trenton area. Preliminary population estimates indicate an adult population of approximately 6,000-14,000 shortnose sturgeon occupying the upper tidal Delaware River.

AN - 36405310; 1654 AB - PURPOSE: Designation of three ocean dumping sites for material dredged from the Calcasieu Channel System of Louisiana is proposed. The preferred alternative would involve designation of three existing interim sites as final disposal sites. The sites are located along the entrance to the Calcasieu River in the Gulf of Mexico, from 0.5 to 18.0 nautical miles offshore, in water depths ranging from 2 to 14 meters. Annual disposal of dredged material exceeding 14 million cubic yards would be evaluated to ensure that disposal volumes were within the capacities of the disposal sites. POSITIVE IMPACTS: Designation of the interim sites as permanent sites would provide environmentally and economically acceptable locations for disposal of dredged material. The sites are in a high-energy inshore area where waves, currents, wind, and tidal actions mix and redistribute the sediments, causing disposed material to be dispersed gradually over the bottom. NEGATIVE IMPACTS: Dredged material disposal would result in temporary localized turbidity that could be visible from the shore. Benthic organisms would be smothered by material deposition.

AN - 36381555; 1660 AB - PURPOSE: Enlargement of the Mississippi River and Tributaries (MR&T) levee to hurricane grade from City Price to Venice in Plaquemines Parish, Louisiana is proposed. This supplement to the final environmental impact statement (FEIS) of 1975 proposes a project design that differs significantly from that previously proposed. The 1975 FEIS considered construction of a barrier levee from Bohemia to a point 10 miles above the Head of Passes on the east bank of the Mississippi River and from Fort Jackson to Venice on the west bank. The currently proposed plan would involve raising the MR&T west bank levee to an elevation of 17.0 National Geodetic Vertical Datum (NGVD) from river mile 44.0 at Price to river mile 20.0 at Fort Jackson and to 16.0 NGVD from Fort Jackson to river mile 10.0 at Venice. This would represent an increase of grade ranging from approximately six inches in the upper sections to three feet in the lower sections. A 0 to 120-foot uncompacted fill stability berm would be constructed landside of the levee, where required, and a 45- to 55-foot uncompacted fill wave berm would be constructed throughout the entire project reach on the river side of the levee. The wave berm would be armored with 100,000 cubic yards of shell and 500,000 tons of riprap. Where possible, the landside toe of the new levee would coincide with the existing MR&T levee toe. In sections where stability conditions do not permit the use of the existing MR&T alignment, levee setbacks or floodwalls would be provided. The levee and associated berms would require 6.2 million cubic yards of fill, requiring removal of 19 million cubic yards of material from an 800-acre batture area on the east side of the river. The borrow area would be dredged to a depth of 15 to 25 feet. In areas where the west-side batture exceeded 200 feet, a 60-foot-wide flotation channel would be constructed adjacent to and riverside of the levee to allow the placement of fill material. Material removed from the channel would be placed in the berm or levee. Fish and wildlife mitigation measures associated with the project would include construction of delta splays on the Delta National Wildlife Refuge, various structural measures to retard saltwater intrusion, creation of marshes by breaching levees, purchase of nondevelopment easements on tracts of secondary levee forest, and planting of bottomland hardwood trees on low-quality habitat lands. Estimated first cost of the project is $84.0 million, and annual operation and maintenance costs are estimated at $240,000. Depending on the amortization rate, the benefit-cost ratio of the project would range from 0.64 to 1.7. POSITIVE IMPACTS: Enlargement of the levee system would provide protection from hurricane surges, reducing hazards to life and property, and enhancing the usefulness of protected lands. Annual flood protection benefits would be valued at $9.2 million to $9.6 million. Fish and wildlife mitigation measures would provide $12,000 to $13,000 worth of annual benefits. NEGATIVE IMPACTS: Implementation of the project would displace 13 acres of enclosed levee forest, more than 800 acres of batture woodlands, 34 acres of farmland, 15 houses, and 25 trailers. Approximately 614 acres of river bottom would be affected by levee placement, borrow material removal, and dredging of flotation. Batture spawning areas adjacent to the river would be lost. Three cultural resource sites would be destroyed, and project structures would have visual and could have physical impacts on outbuildings of Fort Jackson, an historic site. Approximately 210 person-days of recreational use along the river would be lost. Noise in excess of 84 decibels on the A-weighted scale would be experienced by persons residing in 650 structures during construction. The raised levee would represent an increase in its visual intrusion on the river.

AN - 36388410; 1662 AB - PURPOSE: Implementation of a flood control project for urban and rural reaches of the Souris River in North Dakota and Saskatchewan, Canada is proposed. The project would be developed and operated jointly by the United States and Canada and would involve purchase of flood storage capacity in Alameda and Rafferty reservoirs in Saskatchewan, operation of a diversion channel from the Boundary Reservoir to the Rafferty Reservoir to minimize peak flood flows on the Souris River below Long Creek, and modification of the gated outlet at the Lake Darling Dam. The Rafferty Dam, which would lie six kilometers northwest of Estevan on the Souris River, would be a homogeneous earth fill structure with an elevation of 550.5 meters and would inundate 12,050 acres. The maximum flood pool would have an elevation of 554 meters, a volume of 513,000 acre-feet, a surface area of 15,400 acres, and a length of 41 miles. The primary purpose of the Rafferty Reservoir would be to provide cooling water for the Shand Thermal Station. In addition to its function as a cooling reservoir and flood storage impoundment, the Rafferty Reservoir would provide municipal water for Weyburn and Estevan and irrigation water for agricultural lands. Construction of the Rafferty Dam would commence in the spring of 1988 and end in the fall of 1989. The Alameda Dam, which would lie 15 kilometers upstream of the confluence of Moose Mountain Creek with the Souris River, would be an earth fill structure creating a reservoir with a maximum flood pool elevation of 579 meters, a flood pool volume of 111,600 acre-feet, and a flood pool surface-area of 5,470 acres. The maximum flood pool would extend 15 miles. In addition to flood control storage, the Alameda Reservoir would provide recreational opportunities, municipal water supply, and irrigation for agricultural lands. The Alameda Dam would be constructed over two construction seasons beginning in 1989. The existing Boundary Dam and Reservoir, which is used to cool a thermal electric plant and to provide municipal water to Estevan, would be relieved via a diversion channel leading to Rafferty Reservoir when peak spring flood flows were anticipated. Modifications at the Lake Darling Dam would consist of the replacement of existing low-flow outlet works with a new conduit to allow operation of the dam for flood control purposes. Minor structural components to be implemented in association with operation of the project would include urban levee improvements; relocation; ring levee protection, or elevation of rural residences affected by flooding; and purchase of flowage easements. Mitigation of wildlife habitat impacts due to project structures and operations would consist of improvements to refuge water control structures, spillways, and dams. Evaporation sharing arrangements between Saskatechewan and North Dakota would be included in the project plan. The estimated cost of the project is $73.7 million, and the benefit-cost ratio is 1.8. POSITIVE IMPACTS: Operation of the project, which would be completed in 1991, would provide water supply and flood control benefits to Saskatchewan, provide 100-year flood protection benefits to the city of Minot, North Dakota, and significantly reduce flood damages along the main stem of the Souris River in North Dakota. Average annual benefits would be worth $7.3 million. NEGATIVE IMPACTS: During nonflood years, the project would increase agricultural and livestock encroachment and encroachment of upland plant species on low-lying wetlands, floodplain forests, and grasslands. The potential for water shortages and avian disease problems within national wildlife refuge lands would increase somewhat. During flood years, the project could result in some conflicts related to regional water supply. Inundation of new land areas due to storage of flood waters could reduce water quality in some surface flows. Preflood drawdown of reservoir waters could increase winter-kill of aquatic resources in Lake Darling and the Souris River. Prolonged flooding during flood years would result in losses of grassland, wetland, floodplain forest, farmland, and associated wildlife habitat, including refuge habitat.

AN - 36407267; 1663 AB - PURPOSE: Implementation of two water resource projects along the Hocking River at Logan in Hocking County and at Nelsonville in Athens County, Ohio is proposed. This information report, which supplements the final environmental impact statement on the project, addresses design modifications to the components of the project to be implemented at Logan; the modifications result from detailed planning and engineering studies. According to the original plan, the Hocking project would have involved modification of 2.7 miles of channel, construction of 3,500 feet of levee along Oldtown Creek, development of associated recreational facilities, and implementation of wildlife mitigation measures. Mitigation measures would have included four riffles and pools, planting of shade trees on the floodway at the edge of the river, and other wildlife plantings. Major modifications proposed in this report would include shifting the floodway widening direction from the right to the left bank between the railway bridge and the U.S. 33 bridge, eliminating 1,600 feet of widening along the right bank and 300 feet of widening along the left bank between the U.S. 33 bridge and the Mulberry Street bridge, widening of an additional 600 feet of floodway along the left bank downstream of the U.S. 33 bridge and an additional 400 feet along the right bank upstream of the Mulberry Street bridge, widening along 3,700 feet of left bank and 3,000 feet of right bank downstream of the Mulberry Street bridge, and excavating a high-flow channel to divert flows through an existing borrow pit at the downstream terminus of the project. Stone projections would be placed as appropriate to ensure bank stability. Excavated materials would be placed at three sites along the left side of the river in the upper project area and along the left side of the river below Mulberry Street, completely filling two borrow pit ponds. The modified plan would also include changes in selective bank clearing, instream habitat improvement measures, and planting of shade trees. POSITIVE IMPACTS: Partial flood protection would be provided for residents of Logan, enhancing the security and general welfare of the population. Needed recreational development would be provided, future access to the river ensured, and open space preserved along the riverfront and in areas that otherwise would be developed. NEGATIVE IMPACTS: Modification of the channel would damage aquatic habitat, reducing the productivity of fish and other aquatic organisms. Woodland and other terrestrial habitat would be displaced.

AN - 36388443; 1664 AB - PURPOSE: Replacement of Lock and Dam 7 (L&D 7) on the Monogahela River at Greensboro in Greene and Fayette counties, Pennsylvania is proposed. The existing L&D 7 is located at river mile 85.0. The new lock and dam would be built 2.8 miles downstream of the existing structure at a site near the community of Grays Landing. A February 1986 information report, supplementing the final environmental impact statement (FEIS) of January 1984 (revised April 1984), addressed impacts associated with moving the location of the new L&D 7 site at river mile 82.0, approximately 1,000 feet downstream of the previously proposed site. This 1987 information report, which also supplements the FEIS on replacement of L&D 7 and L&D 8, addresses changes in previously reported real estate acquisition policies and updates the historical and archaeological resources management activities associated with the L&D 7 project at Grays Landing. The impacts resulting from real estate acquisition and a discussion of cultural resources management activities were presented in the FEIS; changes in the magnitude of these impacts are not considered significant. This information report is based on the maximum number of structures that could be affected by the project's easement acquisition policies, the actual number of which would most likely be less than indicated in this report. Due to changes in area hydraulics that would be caused by the operation of L&D 7, standard and modified flowage easements would be purchased from individual property owners. Standard easements, which remove property owners' rights to retain or place standing structures on their land, would be purchased in the following areas: (1) all land between river mile 82.0 and river mile 85.0 from elevation 763 National Geodetic Vertical Datum (NGVD) to elevation 791 NGVD; and (2) all land affected by the 11-year flood (796 NVGD to 800 NVGD) that would lie upstream of the new L&D 7 to the Point Marion L&D at river mile 90.8. Modified easements, which allow owners to place nonresidential buildings and floodproofed residential buildings on their land, would be purchased along the three-mile reach of the river immediately upstream of the new L&D 7 site, a reach that would be subject to a 15-foot pool raise during operation of the lock and dam. All costs for floodproofing would be the responsibility of the government. Residences that could not be floodproofed would be removed. POSITIVE IMPACTS: Above the elevations of the 11-year flood, L&D 7 would reduce the level of flood flows in areas upstream of the dam. NEGATIVE IMPACTS: Construction of the water control structure would create new hydraulic conditions in the project area, increasing flood stages. A 15-foot-deep, three-mile-long pool rise would occur between the new L&D 7 location and existing L&D 7. Flood stages would be increased up to the elevation of the 11-year flood upstream of L&D 7 to river mile 90.8. Two residential structures would be purchased and removed from standard easement area (1). Two residences, one mobile home, 10 commercial/public buildings, and four garages/sheds would be purchased and removed from standard easement area (2). Purchase of modified easements would affect 72 residences. The project would adversely affect two sites potentially eligible for inclusion in the National Register of Historic Places.

AN - 36405159; 1609 AB - PURPOSE: Construction of flood control measures for Corte Madera Creek in Marin County, California is proposed. The preferred alternative as presented in this supplement to the February 1979 draft environmental impact statement is the 1985 Floodwall Plan. The plan would require construction of 2,450 feet of floodwalls (1,080 feet on the right bank and 1,370 feet on the left bank) between Corte Madera Creek and the residences on Sylvan Lane and Sir Francis Drake Boulevard. The Lagunitas Road Bridge would be replaced. A 270-foot reach of reinforced concrete channel would be constructed from the terminus of the existing flood control channel to the proposed sediment trap. A three-foot-wide, low-flow notch would be constructed along the channel centerline to facilitate fish passage. Four pools would be spaced at 60-foot intervals to provide resting areas for fish during migration. A 270-foot-long sediment trap, designed to accommodate 3,200 cubic yards of material, would be provided as well. Rehabilitation of fish rearing areas above the Lagunitas Road Bridge would be included in the project design. Biotechnical bank stabilization measures would be provided along portions of the bank. POSITIVE IMPACTS: Residences along and downstream of the project would be provided full standard project flood (SPF) protection, and existing flood control features of the downstream units would become fully functional. The project would significantly reduce erosion and sedimentation in the study area. Functioning of downstream flood control facilities would be enhanced, and downstream damages from the SPF would be eliminated. Within the study area, the floodwalls would protect private homes, public buildings, and public facilities. The project would provide substantial long-term benefits to automotive transportation in the area due to elimination of roadway flooding. Costs due to flood damage repairs would decrease significantly. NEGATIVE IMPACTS: The natural channel of the creek would be replaced by concrete walls and associated facilities. Access to the creek would be restricted, and riparian woodland would be lost. The Lagunitas Road Bridge, a site listed on the National Register of Historic Places, would be replaced. Vegetation diversity and abundance would decline, and water quality would be reduced as a result. Wildlife habitat associated with the natural channel and associated vegetation would also be reduced. Travel corridors currently open to mammals would be disrupted, and loss of trees would affect arboreal wildlife. Fish-spawning and -rearing habitat would be lost.

AN - 36395925; 1610 AB - PURPOSE: Construction of a 600-foot second lock at Locks and Dam No. 26 (Replacement) on the Mississippi River near Alton, Illinois is proposed. Under the preferred alternative, the second lock (600 feet by 110 feet) would be constructed between the authorized lock and the Illinois bank. The concrete-and-steel lock would be placed on foundation piling. The staging area would be on the Illinois bank adjacent to the construction site and riverside of the levee. A portion of the area was built up to an elevation of 434 feet NGVD during construction of the first lock and is approximately 18 acres in extent. If additional area is required for staging, the contractor could either use areas in Missouri remaining from the construction of the first lock that would not be inundated by the new pool or work from barges in the river. A cofferdam would be created to allow for construction of the second lock. Following completion of the second lock, the cofferdam would be removed and sand from the cells would be dumped on the Missouri side of the river. Some material would be needed to build up the Illinois bank to create an esplanade. Due to the depth of the channel on the Illinois side of the river, foundation restoration would be required prior to construction of the lock. This supplement to the draft environmental impact statement of September 1986 responds to comments on the draft statement concerning fish and wildlife mitigation and low probability/high impact events and cumulative impacts of the project. POSITIVE IMPACTS: Operation of the lock would increase commercial river traffic significantly. Traffic levels would reach 174 million tons by 2020, representing a 25 percent increase over current levels. Average annual national economic development benefits would amount to $152 million. The additional lock would function as a backup for the existing lock, reducing the possibility of delays due to lock failure. NEGATIVE IMPACTS: An increase in river traffic would result in increased erosion, suspended sediment, and backwater sediment. Backwater recreational opportunities would be decreased due to sedimentation, and bank erosion and impoundment drawdowns would damage cultural resource sites. National wildlife refuges and other wildlife habitat would be damaged in some areas, degrading commercial and sport fishing, waterfowl hunting, and furbearer trapping.

Preparation date: November 13, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HARDROCK MINERAL LEASING ON THE MARK TWAIN NATIONAL FOREST, CARTER, OREGON, AND SHANNON COUNTIES, MISSOURI. AN - 36396209; 1579 AB - PURPOSE: Issuance of two hard rock mineral preference leases, encompassing a total of 3,700 acres within the Mark Twain National Forest in Carter, Oregon, and Shannon counties, Missouri, is proposed. The 119,000-acre study area is bordered on the south by the Eleven Point National Scenic River, on the west by the Ozark National Scenic Riverways, and on the southeast by the Irish Wilderness. Characterized by well-developed karst terrain and rolling hills, the area is dissected by numerous streams with major drainages provided by the Eleven Point and Current rivers. Lease developments would focus on lead, zinc, and copper. The preferred leasing alternative would change visual quality standards to permit mineral activities over a larger percentage of the area than is currently allowed. Stipulations to protect sensitive visual qualities in the area would include prohibition of tailings impoundments within areas visible from Highways 19, 99, J, and K; Forest Roads 3152, 3174, and 3190; the Eleven Point River; and the Ozark and Blue Ridge trails. In addition, power lines would not be permitted within the foreground of Highway K or Forest Roads 3169, 3173, or 3174, and mill sites and haul roads would be restricted from sensitive areas. The restriction against tailings impoundments would affect 60 percent of the study area; the power line restriction would affect 52 percent; the mill site restriction would affect 50 percent; and the haul road restriction would affect 39 percent. POSITIVE IMPACTS: Implementation of the preferred alternative would increase the land available for mineral development and production activities, particularly those associated with lead mining, while maintaining existing water quality objectives, protecting areas of national significance, and protecting threatened and endangered species and their habitat. The cost of implementing mineral enterprises in the area would decrease significantly. NEGATIVE IMPACTS: Topography and other visual and recreational characteristics would be altered by mineral developments within the study area, and habitat characteristics would be altered. Some soil erosion would occur at sites cleared of vegetation for facility construction or other uses, and mining activities could alter water flows in some areas. The risk of release of tailings or mill wastes would be presented by the preferred leasing alternative, and fugitive dust could enter wetland areas. Impoundments located in floodplains would cause a long-term loss of floodplain values. LEGAL MANDATES: Mining and Minerals Policy Act of 1970 (30 U.S.C. 21a).

Preparation date: November 12, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MARYLAND ROUTE 100 EXTENDED FROM INTERSTATE 95 IN HOWARD COUNTY TO MARYLAND ROUTE 3/INTERSTATE 97 IN ANNE ARUNDEL COUNTY, MARYLAND. AN - 36402213; 1603 AB - PURPOSE: Extension of Maryland Route (MD) 100 from Interstate 95 (I-95) in Howard County to MD 3/I-97 in Anne Arundel County, Maryland is proposed. The 7.5-mile extension would be a four-lane freeway with full control of access and interchanges at U.S. 1, Race Road, MD 295, MD 713, MD 170, and MD 3/I-97. More specifically, the freeway would extend from I-95 along the alignment of existing MD 100, cross beneath U.S. 1 at a point 950 feet north of MD 176, continue southeasterly between the MD 100 Business Park on the north and Dorsey Business Center on the south, cross over the Chessie System Railroad and O'Conner Road, continue easterly to an interchange with MD 295, parallel Maryland Route 176 on the south, shift onto the existing Dorsey Road right-of-way at MD 713, cross over the Amtrack railway and MD 170, continue on an alignment north of MD 176, and enter Friendship Park and tie into MD 100 and I-97. Numerous highway and road relocations would take place along the traversed roads, and some roads would be terminated. Noise abatement measures could be implemented at one noise sensitive site where noise levels would otherwise exceed federal standards. Estimated costs of construction, rights-of-way acquisition, and relocation assistance for the project are $133.2 million, $22.8 million, and $1.0 million, respectively. POSITIVE IMPACTS: Construction of the highway segment would improve traffic operations through and within the study area by providing a new east-west highway facility for Anne Arundel and Howard counties, areas planned for extensive commercial and industrial growth. Congestion along other major routes in the study area would be relieved, and the general development plans for the two counties would be supported. Accessibility to community facilities, parks, and public recreation areas in the project would be improved by separating local and through traffic and maintaining the existing road network via highway separation structures. Congestion along MD 176 would decline significantly. NEGATIVE IMPACTS: Rights-of-way development would result in acquisition of 22 residential units, 10 of which house minority families, and 7 businesses. Several roads would be terminated or rerouted in the Race Road and Wright Road areas, resulting in more circuitous routes for drivers attempting to reach MD 176. Removal of traffic from MD 176 would reduce income for businesses along that through highway. One or more streams and the 28.5 acres of associated floodplains would be traversed, and 56.9 acres of wetlands, 56.0 acres of woodlands, and 69.7 acres of old field habitat would be impacted. Ten areas sensitive to noise would be exposed to significant noise levels due to traffic along the proposed highway segment, and federal noise standards would be violated under some traffic conditions. Smith Farm, a site eligible for inclusion on the National Register of Historic Places, would lose some of its land to highway rights-of-way, although no buildings would be affected. Four archaeologic sites would be impacted, and 14.2 acres of parkland would be displaced. The project would encroach on four significant geological sites.

AN - 36400516; 1602 AB - PURPOSE: Construction of approximately four miles of two-lane highway from a point 0.5 mile south of Seldom Seen Road to Buskirk Hollow Road within the Maryland Route (MD) 36 corridor in the Georges Creek Valley area of Allegany County, Maryland is proposed. The alignment of the highway would begin at the southern end of Lonaconing, at a point on the existing MD 36 pavement approximately 0.3 mile south of Georges Creek crossing, diverge from existing MD 36 to follow along the east side of Georges Creek, and climb the wooded mountainside through an undeveloped area to intersect Jackson Mountain Road near its connection with Allegany Street in the vicinity of the eastern limits of Lonaconing. From that point, the highway section would proceed northward across the Jackson Run Valley on a curved high-level bridge to a point on the mountainside at the rear of the residential development on the east side of Big Vein Hill Street. The highway would then follow the old railroad bed at the base of Dan's Mountain to the Hill Run Valley, cross the valley and Water Station Run Road on a curved high-level bridge, follow the curved face of the mountainside northward along the east side of Georges Creek, pass behind Georges Creek Elementary School, and intersect with Quinn Street near its eastern terminus. The highway would then cross Warnick Road, pass over Elklick Run via a bridge structure, and proceed to its terminus. The relocated section of MD 36 would consist of a 24-foot roadway with 12-foot shoulders and would provide for a design speed of 50 miles per hour. The pavement of existing MD 36 south of Georges Creek bridge would be used as part of the channelized intersection connecting relocated MD 36 and Main Street in Lonaconing. Road relocations, channelized intersections, and other minor changes to connecting roads would accompany the project. The estimated cost of the facility is $26.5 million. POSITIVE IMPACTS: The new facility would separate local and through traffic within the transportation corridor and remove a significant number of trucks from Lonaconing. Overall traffic flow on this major north-south arterial, which connects Westernport and the Frostburg-Cumberland area and serves all the development in the Georges Creek Valley, would be improved. Substandard highway sections through Lonaconing would be upgraded to provide adequate levels of service. NEGATIVE IMPACTS: Rights-of-way development would displace 22 families and 1 business, 90.1 acres of woodland, and 14.9 acres of wetlands. Approximately five acres of floodplains would be affected, and six streams would be traversed.

AN - 36400477; 1574 AB - PURPOSE: Implementation of a plan to remedy ordnance contamination on 1,897 acres of open space in the Tierrasanta Community, formerly a part of Camp Elliott in San Diego, California, is proposed. The ordnance items and debris consist of a wide range of World War II and Korean War weaponry from 0.22-caliber small arms to 155-millimeter howitzer rounds. Based on an analysis of existing records, reports of previous clearance operations, and a statistical survey of randomly selected sites within the project area, ordnance contamination ranges from 0.28 to 29.3 items per acre on the surface and 3.0 to 90.7 items per acre beneath the surface. Approximately 87 percent of the ordnance contamination lies within six inches of the surface and 94 percent lies within 12 inches of the surface. Approximately one percent of the ordnance contamination constitutes a potentially explosive hazard. The following remedial actions would be undertaken: (1) reacquisition of a 167-acre tract north of Naval Air Station Miramar; (2) installation of fencing along the southern rights-of-way for the proposed State Route 52 through the project area; (3) clearance of ordnance after identification via electromagnetic locators on 358 acres of the Tierrasanta Norte residential development and on 56 acres along the eastern boundary of the project area proposed for inclusion in the Mission Trails Park; (4) clearance of ordnance after identification via electromagnetic locators on 146 acres along the eastern border that would be cleared of vegetation via manual methods and controlled burning; (5) implementation of no action within the 58-acre Regency Hill residential development on the southern tip of the project area and within a 43-acre tract on the back side of a hill along the eastern boundary of the project area; and (6) clearance of ordnance after identification via electromagnetic locators on the remaining 774 acres of open space that would be cleared of vegetation via manual methods. POSITIVE IMPACTS: Removal of ordnance from the area would be essential to maintenance of public safety within the developing area under consideration. Clearance of the area would allow implementation of the following projects in the affected area: (1) construction of a portion of State Route 52 connecting Interstate 15 to Santee; (2) development of the Tierrasanta Norte residential community; (3) construction of the Regency Hill development; and (4) development of Mission Trails Park to the east. NEGATIVE IMPACTS: Pruning or burning of sensitive southern oak woodland, sycamore, scrub oak, and willow woodland could be necessary. Burning would temporarily mar visual quality and degrade ambient air quality. Cutting and burning of vegetation could result in erosion.

Preparation date: November 6, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - US 220 FROM STEED IN MONTGOMERY COUNTY TO ULAH IN RANDOLPH COUNTY, NORTH CAROLINA. AN - 36388479; 1605 AB - PURPOSE: Construction of a 13-mile section of four-lane highway to connect existing four-lane sections of U.S. 220 in Montgomery and Randolph counties, North Carolina is proposed. The project would extend southward from the existing four-lane section near the intersection of U.S. 220 and NC 134 south of Asheboro, run along the west side of existing U.S. 220, and end at the intersection of U.S. 220 and U.S. 220A near Steed. A typical highway cross-section would feature two 24-foot pavements separated by a 46-foot grass median and flanked by 10-foot shoulders. Rights-of-way, which would provide full control of access, would be 350 feet at the widest. Interchanges would be constructed at State Route (S.R.) 1121, S.R. 1110, S.R. 1354, and U.S. 220A. Grade separation structures would be provided at S.R. 1127 and S.R. 1356. S.R. 1132, S.R. 1124, S.R. 1125, and S.R. 1348 would be terminated. The highway would have a design speed of 70 miles per hour (mph), although the posted speed limit would be 55 mph. Average annual daily traffic along the new segment of highway would range from 3,500 to 7,800 vehicles per day in 1987 and from 6,500 to 13,300 vehicles per day in 2007. The estimated cost of the project is $45.1 million, including $5.4 million for the purchase of rights-of-way. POSITIVE IMPACTS: Connection of the two existing segments of four-lane U.S. 220 would improve a major route linking the Greensboro, North Carolina area and South Carolina. Direct road user cost savings would result from more efficient and safer vehicle operation and reduced travel time between points served by the existing section of highway. Residents living along the existing highway would benefit from the removal of through traffic from their proximity. NEGATIVE IMPACTS: Rights-of-way acquisition and highway construction would result in displacement of 25 homes and 472 acres of woodland and cleared land. Some prime farmland would be lost. Traffic-generated noise would increase significantly along the new alignment. Construction activities would result in erosion and siltation of streams, and wildlife habitat would be removed or destroyed.

AN - 36400382; 1611 AB - PURPOSE: Continuation of dredging to harvest clam shells in lakes Pontchartrain and Maurepas, Louisiana, as allowed under 5-year permits issued in 1982, is proposed. The current permits will expire in December 1987. Applicants for permits, which could extend the current limit for up to 10 years, include Dravo Basic Materials Company, Inc. (formerly Radcliff Materials, Inc.), Pontchartrain Materials Corporation, and Louisiana Materials Company, Inc. Clam shells have been harvested from the lakes area since 1933 by means of hydraulic dredges. Seven dredges are currently licensed to operate in the Lake Pontchartrain area. Dredges are either self-propelled or propelled by tugboat and move in a circular pattern at an average speed of roughly two miles per hour. Each dredge is equipped with a suction device that is either pushed or pulled through the upper 20 to 30 inches of bottom sediment. A typical trench cut by the suction device is approximately four to six feet wide and two to three feet deep. Separated sediment and water are discharged into the lake. POSITIVE IMPACTS: Continued harvesting of clam shells in the lakes would support a local industry and provide material, characterized by strength, low weight and bulk, and interlocking properties, for the production of cement and the construction of roadways, parking lots, drill pads, and levees. The shells would also be used for lime manufacture, acid neutralization, water purification, petrochemical production, filter media to remove sulfur dioxide from powerplant smoke stack emissions, pharmaceutical production, and poultry feed. The shells could be used to provide cultch material to provide suitable substrate for oyster production. The shell industry provides direct and indirect employment and generates royalties and taxes for the state. NEGATIVE IMPACTS: Dredging activities would cause temporary, localized turbidity and could result in long-term increases in suspended solids in the two lakes. Shell dredging could continue the decline in large clams and in other degradations of the benthic community. Kemp's (Atlantic) ridley sea turtle and the loggerhead sea turtle, which are, respectively, endangered and threatened species, could be affected by continued dredging, although biologic assessments have concluded that impacts to these species would be negligible.

Preparation date: October 28, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TRINITY RIVER AND TRIBUTARIES, DALLAS, DENTON, AND TARRANT COUNTIES, TEXAS. AN - 36401782; 1616 AB - PURPOSE: Cumulative impacts of numerous unrelated development projects under consideration within the floodplains of the West Fork and Elm Fork of the Trinity River in the Dallas/Fort Worth metroplex of Texas are identified. Criteria for the issuance of federal permits for the development projects are also considered. For hydraulic purposes, the upstream boundary along the West Fork is designated as Riverside Drive in Forth Worth, while the upstream boundary along the Elm Fork is designated as the Lewisville Dam. The downstream end of the study area is designated as Interstate 635 in Dallas. Throughout the impact consideration process, local governments and federal authorities have continued to permit floodplain development projects under interim criteria. A master list of 102 projects known to be under development in or near the floodplain was compiled. As a result of an elimination process, removing duplicate project names, unfiled projects, and other projects that would not affect the floodplain, the baseline situation has been revised since the publication of the draft environmental impact statement. In addition to the baseline situation, revised as indicated above, three plans are under consideration. These plans include: (1) development that would be allowed by local governments in the absence of a major change in regulatory posture; (2) a floodway-based scenario; and (3) a maximum environmental quality scenario prohibiting any additional development activities that would affect the floodplain significantly and requiring screening of various environmental enhancements. Plan (3) would include control of nonpoint source pollution via wet detention basins, tertiary treatment of secondarily treated wastewater, use of sewage sludge for reclamation of barren land, wildlife enhancement measures, provision of additional recreation opportunities, and reintroduction of bottomland forest in selected disturbed areas and selected management measures for wildlife. POSITIVE IMPACTS: Implementation of a regional perspective for development of the floodplain would allow proper evaluation of impacts regarding individual permit decisions. NEGATIVE IMPACTS: Extensive modification of the river channel and/or the floodplain would impact water quality within surface flows of the floodplain.

Preparation date: October 26, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STATE ROUTE 664 - BOWERS HILL/BELLEVILLE CONNECTOR FROM THE ROUTE 58 INTERCHANGE AT BOWERS HILL, CHESAPEAKE, VIRGINIA TO ROUTE 17, SUFFOLK, VIRGINIA. AN - 36381221; 1607 AB - PURPOSE: Construction of 5.99 miles of four-lane, limited-access freeway, to be known as the Bowers Hill/Belleville Connector (State Route (S.R.) 664), is proposed in the northwestern portion of the city of Chesapeake and the northeastern portion of the city of Suffolk, Virginia. The facility would extend northward from an interchange with Route 58 (Routes 64 and 264) at Bowers Hill in Chesapeake to Route 17 in Suffolk. The freeway would feature a 64-foot-wide median and a minimum rights-of-way width of 250 feet. The median and rights-of-way widths from a point just south of Pughsville Road to the northern end of the facility would be designed to accommodate the future relocation of the Norfolk Southern Railway into the median. The interchange with Route 58 at Bowers Hill would be completed, and interchanges would be constructed at relocated Dock Landing Road (Route 663), Portsmouth Boulevard (Route 337), and relocated Pughsville Road (Route 659). Ramps would be constructed on the south side of Route 17 as part of the interchange of Route 664 with Route 17 and Route 164. Grade separation structures would be provided at Jolliff Road (Route 191) and relocated Gum Road (Route 656). A connection would be provided between relocated Dock Landing Road and Woodland Drive on the east side of Route 664. The estimated cost of the project is $78.2 million. POSITIVE IMPACTS: Construction of the connector would link an existing road network that ties into Interstate 64 (I-64) and I-264 on the south and a previously approved section of S.R. 664 at its interchange with Route 17 and Route 164 on the north. The project would constitute the last link in a circumferential interstate highway bypassing the metropolitan areas of Newport News, Hampton, Norfolk, Suffolk, Portsmouth, and Chesapeake. Access to existing and developing residential, commercial, and industrial areas along the freeway corridor would be eased, and the Southeastern Virginia Region Year 2000 Transportation Plan would be forwarded. NEGATIVE IMPACTS: Rights-of-way development would result in the displacement of 22 families, 2 farms, 334 acres of woodland and open land, 49.3 acres of tidal wetlands, 253 acres of prime farmland, and 3 churches.

AN - 36396332; 1566 AB - PURPOSE: Dredging and disposal of polluted sediments from the Ashtabula River in the vicinity of Ashtabula Harbor, Ashtabula County, Ohio is proposed. The Ashtabula Harbor is located along the Lake Erie shoreline in the northeastern corner of Ohio, approximately 55 miles east of Cleveland. Approximately 200,000 cubic yards of toxic sediments and 300,000 cubic yards of heavily polluted sediments would be removed. A clamshell dredge would be used to remove all materials, which would be transported by scow to a staging area in the Ashtabula Lakefront Harbor for dewatering and transportation by truck to the final site. The staging area, near Routes 20 and 11, would include a temporary dredged material storage area surrounded by an earthen dike, two settling basins with standby sand filters, a decontamination area, loading and unloading areas, ditches to control runoff, and an equipment storage area. All material dredged from the river would be placed at a privately owned waste disposal facility between LaBounty Road and the company's existing nonhazardous supernatant ponds. Entrance to the facility would be on Middle Road, and the exit would lead to LaBounty Road. The disposal site would encompass 15 acres for disposal proper, 3.5 acres for support facilities, and 15 acres east of LaBounty Road for stockpiling of materials excavated during preparation of the facility. After the disposal operation, the site would be capped with compacted clay, mulched, and seeded to prevent erosion. Groundwater monitoring would be achieved via drilling of wells at the site. The benefit-cost ratio for the project is estimated at 3.57. POSITIVE IMPACTS: Dredging would prevent the random spread of polluted sediments. Long-term improvement of water quality would occur. Navigation facilities in the harbor would be maintained or improved. Businesses relying on Ashtabula River navigation could continue to operate. NEGATIVE IMPACTS: Dredging would cause temporary turbidity and damage benthic communities at dredging sites. Operation of the clamshell dredge would increase noise levels in the vicinity of dredging activities. Some wildlife habitat could be destroyed at the contractor-furnished disposal site.

AN - 36388434; 1570 AB - PURPOSE: The city of Alma and Bacon County, Georgia have applied for a permit from the Department of the Army pursuant to Section 404 of the Federal Water Pollution Control Act of 1972 to discharge fill material into U.S. waters during construction of 14 impoundments and an emergency access road around the northern portion of the land acquired on Hurricane Creek upstream of the proposed Lake Alma Project in Alma. This final supplement to the final environmental impact statement would enable the regulatory authority to evaluate what impacts the mitigation plan associated with the Lake Alma Project would have on the environment of the Alma/Bacon County area. The mitigation plan would consist of dams, roads, and other measures; the plan has already received a Section 404 permit. The current application would require the discharge of approximately 101,030 cubic yards of fill material obtained from on-site high-ground borrow areas. The dams would create 14 greentree reservoirs and lakes with a combined surface area of 194 acres. The greentree reservoirs would be filled beginning November 1 in order to attract migratory waterfowl. Several other measures would be included in the mitigation plan, including construction of a 30-foot-wide emergency vehicle access road, placement of wood duck boxes at 100-foot intervals along the stream bank, and annual planting of roadbed and rights-of-way with a mixture of grain crops to provide food for wildlife. The greentree reservoirs would be drawn down by February 15 when vernal greening begins. While drained, certain areas would be planted with millet or corn. Oak trees would be planted to provide mast production. Appropriate erosion control measures would be used to minimize erosion and sloughing of slopes. Approximately 17 culverts and four bridges would be constructed in association with the access road. POSITIVE IMPACTS: During periods when vegetation is dormant, the greentree reservoirs would provide habitat for waterfowl. Management of the reservoirs would enhance 137 acres of existing wetland and create 23 additional acres of wetland. Implementation of the mitigation plan would increase the recreational potential of the region in association with the construction of Lake Alma. Waterfowl hunting capacity of the area would be increased. NEGATIVE IMPACTS: Formation of permanent pools would result in filling or flooding of approximately 35 acres of existing wetlands. The access road would require 13,000 cubic yards of fill material, of which approximately 2,000 cubic yards would be discharged into wetlands, filling approximately 0.5 acre.

Preparation date: October 22, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 238 FROM NEAR INDUSTRIAL PARKWAY TO THE ROUTE 238/I-580 INTERCHANGE IN THE CITY OF HAYWARD, ALAMEDA COUNTY, CALIFORNIA. AN - 36381192; 1601 AB - PURPOSE: Construction of a 5.4-mile section of Route 238 on new alignment to bypass downtown Hayward, Alameda County, California is proposed. The limits of the project would be a point just south of Interstate 580 (I-580) at the north and a point near the city limits of Hayward and the Industrial Parkway on the south. Two alternatives are under consideration. The expressway alternate would be a 6-lane facility with a 30-foot median and 10-foot outside shoulders, providing for a minimum 50-miles-per-hour (mph) design speed. The expressway would include signalized intersections at A, B, and D streets and grade separations at Grove Way, North Third Street, and Mission Boulevard. Crescent Avenue, C Street, and Highland Boulevard would be terminated without intersecting the expressway. Ten or 11 structures would be constructed to provide controlled access for portions of the expressway. The freeway alternate would be a six-lane facility with full control of access provided via 13 grade separation structures and interchanges and a design speed of 60 mph. Preliminary locations for interchanges would include A and D streets, Carlos Bee Boulevard, Harder Road, Tennyson Road, and Mission Boulevard. Construction of either alternate could be staged, involving initial construction of a four-lane facility and subsequent construction of two lanes within the median. Either alternate would bridge four creeks and Hayward Memorial Park. Regardless of the alternate chosen, the project would involve relinquishment of a part of the existing route from Industrial Parkway to Jackson Street and Foothill Boulevard in downtown Hayward and continuation of Route 92 on Mission Boulevard as a joint route with State Route 185. Either project would also require construction of noise barriers. Cost estimates for construction of the expressway and the freeway as six-lane facilities are $89.0 million and $137.0 million, respectively. POSITIVE IMPACTS: Either alternative would reduce congestion in downtown Hayward and the Foothill-Mission Boulevard corridor. Safety within the affected area would be enhanced, and traffic would be diverted from the heavily congested Nimitz Freeway (I-880). NEGATIVE IMPACTS: Relocation of 15 to 24 business units, 0 to 2 nonprofit organizations, and 0 to 2 community service organizations would be required due to rights-of-way development, and 7 to 9 businesses would be declared as excess. The transportation facility would lie within a seismically active area along coastal California. Project alignment would traverse nine drainage crossings. Expressway traffic would result in violations of air quality standards for carbon monoxide between A and D streets. Noise levels at the playing field associated with Markham School and at Hayward High School would increase somewhat, and the Little Theatre would be exposed to noise levels exceeding state standards. Several historically and architecturally significant structures would be affected by the project. Five acres of dense bay trees and oaks on the upper slopes of stream channels would also be affected, and two acres of riparian wetland would be shaded or filled. Hayward Memorial Park would lose 0.8 to 1.47 acres of land, and Hayward High School would lose 6.5 to 6.7 acres.

NEAR S.R. 3180, APPROXIMATELY 20 MILES, TO I-85 NEAR THE U.S. 29 CONNECTOR IN MECKLENBURG COUNTY, NORTH CAROLINA. AN - 36407065; 1561 AB - PURPOSE: Construction of the East Charlotte Outer Loop within a 20-mile-long corridor between Independence Boulevard (U.S. 74) and Interstate 85 (I-85) within the eastern portion of Mecklenburg County, North Carolina is proposed. Primary alignments under consideration include routes lying in the western, central, and eastern portions of the corridor. A total of 29 alignment segments have been considered. The western corridor would extend, in a generally northerly and northeasterly direction, from Independence Boulevard, parallel Idlewild Road on the west, intersect with Margaret Wallace Road, parallel McAlpine Creek to Pence Road, run along the western edge of the Harrisburg Landfill to Robinson Church Road, parallel Hood Road and Back Creek Church Road on the west, cross N.C. 49, and join the U.S. 29/I-85 Connector. The eastern corridor would extend west from Independence Boulevard, parallel the Mecklenburg /Union County line to Lawyers Road, continue northwesterly to the Plaza Extension, parallel the Mecklenburg/Cabarrus County line to N.C. 49, and continue northwesterly to tie into the U.S. 29/I-85 corridor. The central corridor would extend in a northeasterly direction from Independence Boulevard to Lawyers Road, where it would branch east and west to tie into the eastern and western corridor alignments near Albemarle Road. Typical roadway sections would include four- and six-lane mainline sections, interchanges above and below grade, and standard overpass and bridge structures. Rights-of-way would vary between 300 and 350 feet. Cost estimates for the alternatives range from $213.2 million to $227.3 million. POSITIVE IMPACTS: Access to commercial, industrial, and residential land uses in Charlotte and the towns of Mint Hill and Matthews, as well as unincorporated portions of Mecklenburg County, would be improved significantly, and through traffic would be separated from local traffic. Congestion on existing thoroughfares would decline significantly. The circumferential route would serve the second most rapidly growing area of the county. Air quality in the county, which currently has a nonattainment status for carbon monoxide and hydrocarbons, would be improved due to more efficient traffic movements. The western alignment would provide the highest degree of transportation service, while the eastern alignment would entail the least extensive environmental impacts. NEGATIVE IMPACTS: Rights-of-way development would require displacement of 38 to 273 commercial and residential units, and some of the 13 possibly significant archaeological sites that lie within the alternative corridors could be disturbed or displaced. Biotic communities, including wetland communities, and associated wildlife habitat would be destroyed. Noise would reach significantly negative levels at 88 to 465 structures, and the highway facility would degrade the visual quality of the immediate corridor.

M-5948(1); STATE PROJECT NO. 8.2620601. AN - 36407102; 1562 AB - PURPOSE: Completion of the Silas Creek Parkway in Winston-Salem, North Carolina is proposed. The existing portion of the parkway was built in the early 1960s as an inner ring road for the metropolitan area. The two-mile project would extend from North Point Boulevard to a new intersection on Silas Creek Parkway. The project would consist of full parkway completion from the existing terminus of the parkway at Hope Valley Road to the Bethabara Road/North Point Boulevard intersection and construction of a connector road between Reynolds Road at Fairlawn Drive and the new section of parkway. The new section of parkway would be a four-lane divided facility within a 250-foot right-of-way to allow for construction of two additional lanes in the future. The parkway would be depressed to pass under Reynolds and Polo roads, both of which would be carried over the parkway on structures. The connector would be a four-lane divided facility within a 200-foot right-of-way, with arrangements for possible construction of two additional lanes extending to North Point Boulevard in the future. The estimated cost of implementation of the preferred design is $20.0 million. POSITIVE IMPACTS: Connection of the existing terminus of the Silas Creek Parkway with North Point Boulevard would eliminate an interruption in the existing inner ring road. Large volumes of traffic currently using local streets for through-travel purposes would be able to use the ring road. Disruption of neighborhood activities by excessive traffic on local roadways would be relieved. NEGATIVE IMPACTS: Rights-of-way development would displace 13 homes, 1 business, and 39 acres of upland wildlife habitat and alter the character of the local neighborhood in the Owen Street/Henning Drive area. Construction of a new at-grade intersection with the existing portion of the parkway could require relocation of a stream and displacement of floodplain; water quality could be affected during construction. Land associated with Davis House, an historically significant structure, would be traversed. Noise levels along the corridor would increase significantly.

AN - 36405289; 1556 AB - PURPOSE: Construction of a new marine dry cargo terminal with both rail and highway access on Sears Island, located in Searsport, Waldo County, Maine, is proposed. The terminal would be built on approximately 50 acres of land along the western shore of the new undeveloped 940-acre island. Fully developed, the facility would include a 35-acre marginal wharf with up to six ship berths. Shoreside facilities would include an administration building, storage areas, on-site sanitary waste treatment facilities, and parking areas. The terminal would handle both biobulk (e.g., wood chips, lumber, wood pulp, and potatoes) and containerized cargoes. Development of the facility would require construction of a new 2.3-mile, two-lane secondary highway and a 1.5-mile railroad spur. Access from the mainland would be provided by a 1,200-foot-long solid fill causeway. POSITIVE IMPACTS: The project would provide transportation cost savings to Maine-based industries, especially the forest industry, through reduction in overland travel distances between industrial facilities and port facilities. The terminal would generate jobs directly and indirectly and generally boost the Maine economy, particularly sectors associated with import-export activities. State investments in port facilities would be targeted where new jobs and economic activity are most needed. The primary socioeconomic impacts of the project would include creation of 1,761 person-years of employment during full construction of the pier, creation of 355 permanent jobs, addition of $10.5 million in personal income to the regional economy, expansion of municipal and state revenues by $50,000 and $1.8 million per year, respectively, and transportation cost savings of $2.7 million per year. Secondary impacts would include 1,040 person-years in construction employment, creation of 2,750 new jobs, and generation of $56.0 million in wages and salaries, $3.0 million in state revenues, and $2.9 million to $3.1 million in local revenues. NEGATIVE IMPACTS: The project would permanently displace marine and upland wildlife habitat and disrupt benthic habitat during dredging and dredge spoil disposal activities. The marginal wharf would displace 33 acres of intertidal and subtidal marine habitat. An additional 58 acres would be disturbed due to dredging required to connect the existing channel to the planned ship berths. Site preparation and construction of the terminal would virtually eliminate the 40 acres of upland habitat at the site. Construction of the highway and rail access would result in the loss of an additional 12 acres of wildlife habitat, and the causeway would require filling approximately 3.7 acres of intertidal marine habitat. Secondary impacts would include an additional loss of up to 12 percent of the island's upland wildlife habitat, a 28 percent increase in traffic on Route 1, and some reduction in the visual quality of the island.

AN - 36403403; 1559 AB - PURPOSE: The construction of Forest Highway 11 along a continuous alignment between Hoyt Lakes in Saint Louis County and Silver Bay in Lake County, Minnesota is proposed. The project, which would lie within the Arrowhead region, would include an intermediate terminus at Lake County State Aid Highway (CSAH) 2. The study area's western terminus consists of the junction of Saint Louis CSAH 110 and Saint Louis County Route 346 within the community of Hoyt Lakes. Trunk Highway 61, near Silver Bay and Beaver Bay at Lake Superior's north shore, serves as the study area's eastern terminus. The highway would feature two 12-foot traffic lanes and six-foot shoulders, 4:1 slopes, and a 25-foot recovery area. The design speeds would range from 40 to 60 miles per hour, and the highway would be designed for 10-ton vehicles. The estimated cost of the project is $20.6 million. POSITIVE IMPACTS: The construction of the highway would increase regional accessibility, contribute to continuity in the roadway system, and generally reduce transportation costs. Timber harvest operations would be enhanced by improved access to major wood-processing plants and by reduced travel time and mileage for operators. Access to recreation resources would also be improved. Regional socioeconomics would be improved via enhancement of trade and reduced commuting times between major Iron Range and North Shore industrial locations. Safety of road transport within the corridor would be improved significantly due to highway design improvements. NEGATIVE IMPACTS: The rights-of-way development would affect 43 acres of wetland, and the alignment would cross three trout streams in addition to the four that are already crossed by the existing alignment. A total of 18 other streams would be traversed. Four statutorily defined shoreland areas would be affected, although no direct impacts would occur to protected waters. Ambient noise levels within the corridor would increase by 5 to 14 decibels on the A-weighted scale under worst-case conditions. The visual quality of borrow sites and scenery at stream and river crossings, including a crossing of the Cloquet River, which is listed on the Nationwide River Inventory, would be degraded somewhat. Some wolf mortality could result due to increased traffic in the corridor.

Preparation date: October 14, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GREAT BEND, KANSAS LOCAL FLOOD PROTECTION PROJECT, ARKANSAS RIVER, BARTON COUNTY (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF APRIL 1987) AN - 36406805; 1571 AB - PURPOSE: Implementation of a flood control project for the city of Great Bend, Kansas, is proposed. Great Bend lies near river mile 874 on the left bank of the Arkansas River in Barton County. Walnut Creek meanders approximately three miles north of the city and bends southeastward, passing within one mile of the eastern limits of the city as it flows into the Arkansas River. Little Walnut Creek joins Walnut Creek one mile east of the northeastern corner of existing urban development. This supplemental information report to the final environmental impact statement of April 1987 discusses project design changes and resulting mitigation changes. Salient changes in project design would involve deletion of plans for channelization of the Arkansas River upstream of U.S. Highway 281 at Great Bend and the development of nine borrow areas with a combined surface area of 180 acres. The borrow areas, which would provide levee construction material previously planned to be provided from material removed during channelization, would be developed east of the U.S. 281 bridge between the inside base of the proposed levee system and the Arkansas River. Mitigation measures would include planting of at least 28.5 acres of trees, purchasing of a conservation easement on at least 85 acres of riparian woodland located within the levee, and planting of vegetation for wildlife habitat. POSITIVE IMPACTS: The project would enhance the long-term productivity and well-being of the residents of Great Bend. Mitigation measures would enhance wildlife values in some areas. Elimination of channelization of the Arkansas River would nearly eliminate aquatic and terrestrial losses and significantly reduce woodland losses. NEGATIVE IMPACTS: Project actions would eliminate 27 acres of woodland and 2.2 acres of riparian habitat. The primary loss of woodlands would occur at the mouth of the Little Walnut and Walnut creeks diversion channel. Small, isolated impacts to woodland also would occur as levees are constructed along the Arkansas River. Borrow areas would displace 180 acres of prime farmland.

Preparation date: October 6, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - JOHNSTON ATOLL CHEMICAL AGENT DISPOSAL SYSTEM (JACADS) (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF NOVEMBER 1983). AN - 36380999; 1541 AB - PURPOSE: Disposal of chemical warfare agents by the Johnston Atoll Chemical Agent Disposal System (JACADS) on Johnston Atoll in the southern Pacific Ocean is proposed. This draft supplement to the final environmental impact statement (FEIS) of November 1983 covers disposal of liquid and solid wastes associated with disposal of nerve agents GB and VX and blistering agent HD. Johnston Atoll is located at 16 degrees, 44 minutes north latitude and 169 degrees, 31 minutes west longtiude, making it one of the most isolated atolls in the Pacific Ocean. Johnston Island, the largest island of the Atoll, has increased from 60 acres to 625 acres due to dredge and fill operations. The disposal system for the chemical agents proposed in the FEIS would involve construction and operation of an incineration facility on the western peninsula of the island and disposal of incinerator wastes via drying, drumming, and storage on the island. A liquid incinerator would be used to destory GB and VX agents, while disposal of HD would be via a process involving neutralization and incineration. Waste materials would be reduced to solid salts and, then, compacted and packaged in 55-gallon drums. Alternatives for disposal of solid wastes produced as byproducts of the incineration and packaging process include: (1) disposal by ships in a deep-water site approximately 13 to 19 miles south of the atoll; (2) drying of liquids into inorganic salts and shipping both the salts and other solid process wastes to an authorized landfill or storage site in the United States; (3) discharging of liquid wastes into the ocean via an outfall pipeline from Johnston Island; and (4) drying of liquid brine into salts and storage, along with all unrecyclable solid wastes, on Johnston Island for an indefinite period. Recyclable scrap metal produced by JACADS operations would be sold or disposed of via ocean dumping or placement in a landfill in the United States. Depending on the alternative chosen, costs of disposal of the liquid wastes, salable solid wastes, and nonsalable solid wastes are estimated at $3.3 million to $7.7 million, $34,000 to $82,000, and $3.4 million to $4.2 million, respectively. POSITIVE IMPACTS: By providing a permanent facility to destoy unserviceable or obsolete chemical agents and the byproducts of the destruction process, JACADS would enhance safeguards protecting the biosphere against releases of toxic agents. Ocean disposal of solid wastes would create hard substrate for benthic organisms. Encapsulation of wastes on the atoll would provide habitat for seabirds and protection of shore areas from erosion. NEGATIVE IMPACTS: Construction of ocean disposal sites for wastes would stress and destroy reef organisms, and ocean disposal of solid wastes would bury resident benthos. Use of a U.S. landfill could result in contamination of water resources due to disaster. LEGAL MANDATES: Public Law 91-672 and Public Law 99-145.

Nitrate is converted to ammonia by alkaline reduction with TiCl3 in gas tight reaction vials. Ammonia is determined before and after reduction using a gas-sensing probe and nitrate is calculated by difference. The procedure is simple, inexpensive, and suitable for routine analysis of samples as small as 5 ml. There are no significant interferences and results are comparable to those obtained using automated cadmium reduction.

Water quality in Rocky Fork was significantly worse than the control stream with respect to heavy metals (Cr, Cu, Fe , Ni, and Zn) and ammonia concentrations. Fish species richness and diversity increased downstream in Clear Fork but decreased downstream in Rocky Fork. Pollution-intolerant species (lampreys , darters, sculpins) were present in the headwaters of Rocky Fork and at all sites of Clear Fork. Fish community similarity at midriver sites was significantly greater in Rocky Fork than in Clear Fork. Likewise, similarity of fish communities between corresponding headwater sites was significantly greater than similarity of corresponding downstream reaches, using polluted and unpolluted sites for comparison. Total species richness of fish feeding on generalized invertebrates, benthic insects, and insects-fishes decreased downstream at polluted sites but remained stable in Clear Fork sites. Both headwater sites were dominated numerically by generalized invertebrate-feeding fish. At downstream sites in Clear Fork benthic insectivores became dominant (37-68% of all fishes per season); in Rocky Fork, generalized invertebrate-feeding fish (54-94% of all fishes per season) were present. Fish communities at polluted sites had comparatively lower variability of both trophic structure rank and relative abundance. The smaller populations of fish in these sites were dominated by a few pollution-tolerant species.

In this model the transformation of an oil slick due to advection, spreading, evaporation, and dissolution is considered. For open water conditions, the movement of the oil slick by water current and wind is considered using the drifting factor formulation. For ice-covered conditions, the drift velocity is determined according to the ice roughness and current velocity. The current distribution in the lake is determined by a rigid lid circulation model. In the spreading process the mechanical spreading of the oil slick due to the balance of inertia, gravity, viscous, and surface tension forces is considered, in addition to the dispersion of the surface oil layer. Boundary conditions along the shore are formulated according to the storage capacity of the shoreline. The model can be used for simulating either instantaneous or continuous oil spills. Sample simulations for oil spills in Lake St. Clair are presented. (Author 's abstract) JF - Water Resources Research WRERAO Vol. 23, No. 10, p 1949-1957, October 1987. 5 fig, 2 tab, 38 ref.

AN - 36408791; 1522 AB - PURPOSE: Channel improvements along the Alabama and Coosa rivers in Alabama and Georgia are proposed. Three separate segments would undergo improvements to open a 300-mile navigation channel from the mouth of the Alabama River upstream to Montgomery, Alabama: (1) the Alabama River from its mouth to the vicinity of Montgomery, Alabama; (2) the Alabama and Coosa rivers between Montgomery and Gadsen, Alabama; and (3) the Coosa River between Gadsen, Alabama and Rome, Georgia. Specific activities would include maintenance dredging of approximately 1 million cubic yards annually, predominant use of within-bank disposal areas, maintenance of training dikes on the river below Claiborne lock and dam, maintenance of hydropower facilities, maintenance of lock facilities, and maintenance of project lands, including a number of recreation facilities. Since initial dredging of the project in 1968 and 1969, annual maintenance dredging quantities have increased significantly in the Claiborne lock and dam area. This final supplement to the final environmental impact statement of January 1976 reevaluates operation and maintenance activities in the Alabama River segment. Channel stabilization structures and site-specific disposal areas are proposed. The measures would include construction or modification of training dikes at several locations below Claiborne lock and dam, lowering the dredge reference profile based on reducing the channel design flow from 8,450 to 7,500 cubic feet per second, and expanding the dredging reaches. The number of within-bank disposal areas would be expanded. These areas would consist of unforested lands along the riverbank below the ordinary high-water line and extending riverward. The number of above-bank disposal areas would also be increased. In order to mitigate for the significant wildlife resource losses that would occur due to construction and utilization of the above-bank disposal sites, intensive wildlife management on 645 acres of bottomland hardwood habitat on Bob Woodruff Lake lands is proposed. POSITIVE IMPACTS: Continued maintenance of the system would permit economic development based on river transportation. Small-boat channel maintenance would improve access for waterborne recreational craft and for commercial fishermen along the Alabama River. NEGATIVE IMPACTS: Use of above-bank disposal sites would result in the loss of 183 acres of bottomland habitat, with potential long-term losses of up to 3,300 acres for the remaining 40 years of the project life. Approximately 28 acres of wetlands would also be lost. Streambed degradation below Claiborne lock and dam would affect the stability of the lock and dam.

Preparation date: September 29, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DEER CREEK DAM AND RESERVOIR MUNICIPAL WATER SUPPLY PROJECT, CONVERSE AND NATRONA COUNTIES, WYOMING. AN - 36396375; 1533 AB - PURPOSE: Implementation of a plan for the construction of a dam and reservoir on Deer Creek, a tributary of the North Platte River in southeastern Wyoming, to provide a reliable municipal water supply for the city of Casper, Converse County, Wyoming is proposed. The dam would impound a reservoir of approximately 66,000 acre-feet over 1,050 acres of land. Two alternative scenarios are proposed. Scenario 1 assumes that the U.S. Bureau of Reclamation's (USBR) North Platte project would operate as it has historically, with no changes, including deliveries to the Inland Lakes. The Deer Creek project would be allowed to store water only after all senior water rights have been satisfied and after the Inland Lakes have been filled. The Deer Creek project would realize a firm annual yield of 64,000 acre-feet under this scenario. Scenario 2 assumes that the Inland Lakes would have a current-day Wyoming water right and would be allowed to fill from surplus natural flow after all senior water rights, including the Deer Creek project, have been satisfied. Under this scenario, it is assumed that the Inland Lakes would accrue the natural flow of the North Platte River in Wyoming when surplus was available, then from North Platte project storage, if needed. The Inland Lakes would receive the same amount of water at the same times as they have in the past under this assumption. A firm annual yield of 9,600 acre-feet would be provided by the Deer Creek project under this scenario. The Deer Creek project would involve 1,850 acres of land. Rangelands and free-flowing streams would be converted to a reservoir with adjacent recreation and wildlife management lands. Seven miles of stream fishery would be replaced by a reservoir fishery. A public fishing easement would be provided throughout the six-mile Deer Creek Canyon below the dam. A boat ramp, parking lot, and access roads would be constructed. POSITIVE IMPACTS: The project would provide year-round minimum release flows. This would improve the stream habitat downstream from the dam. An estimated 40 acres of wetlands would be created by the presence of the reservoir. A 490-acre tract of land adjacent to the reservoir would be managed for recreation and wildlife. Recreation benefits of $359,000 per year would be realized by the Deer Creek project in the year 2000. NEGATIVE IMPACTS: Projected releases and release temperatures may adversely affect trout spawning and survival. More than 1,000 acres of various habitat types would be inundated by the Deer Creek Reservoir. Approximately 120 acres of willow-wet meadow habitats would be flooded. Under Scenario 2, critical habitat of the federally endangered whooping crane, the interior least tern, and threatened piping plover may be affected. Eleven recently discovered cultural resource properties that are potentially eligible for the National Register of Historic Places would be impacted. There would be an average annual depletion to the North Platte River of 8,760 acre-feet under Scenario 1 and 11,940 acre-feet under Scenario 2.

AN - 36412175; 1519 AB - PURPOSE: Construction of a new limited access four-lane divided highway, to be known as the Trotwood Connector, and extension of Turner Road on the northwestern side of Dayton in Montgomery County, Ohio are proposed. The 5.29-mile facility would extend southward from State Route (S.R.) 49, at a point north of its intersection with Shiloh Springs Road, to a point on Third Street, approximately 1,000 feet east of Olive Road, where it would connect to the realignment of U.S. 35. More specifically, the alignment would diverge from S.R. 49 to the south between Shiloh Springs Road and Olive Road, curve to the southeast to avoid a residential subdivision and most of the Dry Run Stream corridor south of Shiloh Springs Road, continue directly south to pass between Devonshire and Norfolk avenues, and intersect with U.S. 35. A structure would carry the roadway over the Penn Central Railroad, and intersections would be created at Free Pike, Wolf Creek Pike, Little Richmond Road, Hoover Avenue, and U.S. 35. The facility would be at grade, except for the structure over the railroad. The project would also include construction of a 1.7-mile extension of Turner Road from the existing Turner Road/Wolf Road intersection, across Salem Avenue and Denlinger Road, to an intersection with the Trotwood Connector. Estimated costs of the Trotwood Connector and the extension of Turner Road are $20.3 million and $3.18 million, respectively. POSITIVE IMPACTS: Construction of the new roadways would correct deficiencies in the existing regional transportation system. Congestion at peak hours on U.S. 35 and S.R. 49 would be relieved. An additional north-south link between the most rapidly growing part of Trotwood and U.S. 35 /West Third Street would be provided. Extension of Turner Road to S.R. 49 and to the proposed Trotwood Connector would extend an area beltway into the west Dayton area, greatly facilitating crosstown traffic flow. NEGATIVE IMPACTS: Traffic on the new roadways would increase noise levels in residential areas, and federal noise standards would be violated at some receptors. Construction of the facilities would displace prime farmland, encroach upon several small streams and the shorelines of two small lakes, and require displacement of commercial and residential structures. Segments of riverine woodland, as well as shrubland and old field habitat, would be displaced. Approximately 1.4 acres of land contiguous to a baseball field would also be displaced, and the Turner Road extension would pass adjacent to John Wolfe Park east of Denlinger Road.

AN - 36387564; 1495 AB - PURPOSE: Establishment of an acoustic measurement facility at Behm Canal in the Ketchikan Gateway Borough of southeastern Alaska is proposed to measure and define the acoustic signature of quiet operating submarines and to predict their vulnerability to detection. The facility would consist of an underway measurement site, located in the central portion of the canal; a static measurement site, located northwest of Back Island; and shore facilities, located on Back Island. The 500-yard-wide, 10,000-yard-long underway measurement site would be equipped with tracking arrays that would monitor submarines acoustically as they pass through the site and transmit sounds to the shore facilities. The static measurement site would consist of bottom-moored acoustic measurement arrays similar to those at the underway measurement site. The shore facilites would include an operations area on the northwestern side of the island and the dock area on the western side. A danger area and restricted zones would be established in association with the facility. Construction of the facility would begin in 1989, and operations would be initiated early in 1991. POSITIVE IMPACTS: By providing a facility to measure and qualify the acoustic signature of U.S. Navy submarines, the project would contribute to the maintenance of the nation's defense system. The facility would replace facilities at Carr Inlet, Washington and Santa Cruz Island, California, where man-made noise interferes with operations. NEGATIVE IMPACTS: Shore facilities at Back Island would displace approximately 12 acres of faunal habitat. Site activities would place some pressure on area fauna, and aesthetic values of the island would be depleted slightly. Benthic fauna in the vicinity of the pier would be displaced.

Preparation date: September 18, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NEW SAN CLEMENTE PROJECT, MONTEREY COUNTY, CALIFORNIA. AN - 36411014; 1523 AB - PURPOSE: Construction of a dam on the Carmel River to create a 16,000-, 20,000-, or 29,000-acre-foot reservoir approximately 16 miles southeast of Monterey, Monterey County, California is proposed. Regardless of the alternative storage capacity chosen, the project would involve construction of a 244- to 300-foot roller-compacted concrete dam, with a crest length of 750 to 900 feet, that could be raised to impound as much as 45,000 acre-feet if authorized at some future date. The surface area of the reservoir would range from 240 to 345 acres. The project would also include inlet and outlet structures, fish facilities, wells in Carmel Valley and Seaside, a water treatment plant in Begonia, a management plan for allocation and phasing of yield, and development of passive recreational facilities. Estimated capital cost ranges and annual operation costs for the two-year project are $31.4 million to $43.8 million and $520,000, respectively. POSITIVE IMPACTS: Implementation of the project would provide municipal water supply to meet both short- and long-term needs of the Monterey Peninsula Water Management District, afford drought protection, and restore high-level water quality in the Carmel River. Water supply demands through the year 2020 would be met. Approximately 180 jobs would be created during the construction period. Fish spawning activity would increase significantly. Destruction of riparian vegetation in the area would decrease due to increased groundwater flows. Cooler river waters during the summer would benefit steelhead trout. NEGATIVE IMPACTS: Depending on the alternative chosen, 240 to 345 acres of undeveloped land would be inundated, including 21.5 to 31.0 acres of riparian forest, and a permanent change in the visual quality of the immediate area would result. Approximately 1,450 acres of private lands would be affected by the project, some of which would be purchased and transferred to public ownership. The trihalomethane-generation potential of waters from the new reservoir could be increased during the years immediately following creation of the reservoir. The river channel below the dam would narrow to 40 feet from 80 to 100 feet, increasing flood levels. A section of the river, including some steelhead trout habitat, would be inundated. Residential, commercial, and industrial growth induced by the water supply provided by the reservoir would cause an additional loss of natural areas. Average residential water rates would increase by $3.03 to $4.08 per month, and average commercial water rates would increase by $33.71 to $45.41 per month.

Preparation date: September 17, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - KANAWHA RIVER NAVIGATION STUDY, PUTNAM COUNTY, WEST VIRGINIA: WINFIELD LOCK REPLACEMENT, INTERIM FEASIBILITY REPORT. AN - 36402414; 1532 AB - PURPOSE: Construction of a lock replacement at Winfield Locks and Dam, Kanawha River near Eleanor, Putnam County, West Virginia is proposed. The Winfield Locks and Dam Facility is located at Kanawha River Mile 31.1, approximately 27 miles downstream of Charleston. The preferred alternative would add an additional lock at the existing project site, continue to use the riverward lock, and deactivate the present landward lock. The lock would be 800 feet by 110 feet. Channel widening downstream from the existing Winfield project also is recommended as part of the improvement plan. Mitigation measures include on-site, in-kind replacement of a stream, 21 acres of wetland habitat, and 60 acres of high quality farmland. The plan would require acquisition of approximately 36 acres of land for construction of the lock and approaches and another 145 acres for the disposal of excavated material. Facilities to safely accommodate the public are also included in the plan. The estimated construction cost of the preferred alternative would be $152 million. Annual economic costs for a 50-year project life are $17.5 million. The annual economic benefits would be $70 million, yielding a benefit-to-cost ratio of 4:1. POSITIVE IMPACTS: The key effect of the new lock would be the virtual elimination of waiting tows outside the project approach areas. This beneficial impact would effectively end the recurring disturbance of nearshore habitat by moored tows waiting for passage through the facility. Safety would be improved due to efficient movement of traffic and minimization of congestion. The site would be managed as a wildlife area by the West Virginia Department of Natural Resources. NEGATIVE IMPACTS: Losses of 0.6 mile of stream, wildlife habitat, wetlands, a small pond, and prime farmland due to disposal of excavated material would be mitigated. Construction of the lock would foreclose the urbanization of approximately 180 acres. Four recorded archaeological sites would be impacted. Twenty-eight families occupying 33 mobile or modular homes would be displaced. The lock would result in some minor adverse impacts to small streams and the Kanawha River.

AN - 36399511; 1528 AB - PURPOSE: Implementation of a plan for navigation improvements to the Claremont Terminal Channel, Jersey City, New Jersey is proposed. The selected plan calls for dredging a 1.6-mile-long, 34-foot-deep, 300-foot-wide centrally aligned channel that narrows and adjoins the land at its western end and flares at its eastern end to join the main navigation channel through New York Harbor. The material to be removed (1.7 million cubic yards) would be disposed at a shallow ocean disposal site currently utilized for such material (mud dump). Costs to strengthen an old retaining dike along the northwestern edge of the waterway have been included in the project costs. Silt screens should be used in front of the mudflat not protected by the dike to minimize sedimentation. Dredging in this area would be avoided during the summer to prevent creation of an anoxic environment. Cost of the project is estimated at $12.97 million. POSITIVE IMPACTS: The plan is environmentally acceptable in that the deeper channel would increase tidal flushing and improve long-term water quality in the channel, as well as reduce vessel emissions and chances for spills and accidents. NEGATIVE IMPACTS: Dredging impacts would be minimal and short-term and confined to previously disturbed areas; shoal habitat would essentially remain the same except for the loss of a small, 1.5 acre, isolated shoal in the backwater portion of the channel.

TAGS would parallel the existing Trans-Alaska oil pipeline system in its entirety and a portion of the authorized but as yet unconstructed Alaska Natural Gas Transportation System. TAGS would include 10 compressor stations constructed at regular intervals along the pipeline to provide pressures ranging from 1,100 to 2,220 pounds per square inch, an LNG plant that would include four LNG processing units to liquefy gas at minus 259 degrees Fahrenheit and four LNG tanks, and marine terminal facilities. The operations and control center for the TAGS projects would be located in Valdez, headquarters and administration offices in Anchorage, and maintenance facilities in Fairbanks. TAGS would have a throughput of 2.3 billion cubic feet of conditioned natural gas. Gas pumped and processed by TAGS would be liquefied and exported by tanker to Japan, Taiwan, and Korea. POSITIVE IMPACTS: Exports of LNG allowed by the TAGS system at full operating potential would reduce the U.S. balance of trade deficit by $2.5 billion annually. Construction and maintenance of TAGS would provide substantial support to the area employment base. NEGATIVE IMPACTS: An employment boom during construction of TAGS would result in high levels of unemployment following the completion of the project, placing some burden on state and local social services. Approximately 23,000 acres of vegetated land would be cleared during construction, and moderate but long-term land use impacts would affect approximately 8,000 acres within the pipeline rights-of-way and areas occupied by related facilities. Operation of the terminal, compressor stations, and LNG plant would cause ongoing disruptions to ambient environments. Some surface and groundwater would be consumed during construction, and streams would be affected by turbidity. The marine terminal would displace 100 acres of benthic habitat, and an undetermined loss of seabird and waterfowl habitat would occur at Anderson Bay. Disturbance of 3,200 acres of wetland would occur, and Dall sheep winter range would be disturbed. Riparian moose habitat and swan and loon habitat would be displaced, and large game mortalities would occur in the Delta Junction area. Disturbance of endangered Arctic peregrine falcons and their prey could result from construction activities. Wilderness and other recreational values would be reduced in the area, and subsistence resources would be disturbed during construction.

AN - 36381433; 1529 AB - PURPOSE: Implementation of a comprehensive flood control plan for the 662,000-acre Buffalo Bayou watershed, which includes most of the Houston metropolitan complex of Texas, is proposed. The basin, which has an average width of 25 miles, extends 50 miles from its western headwaters in Waller and Fort Bend counties to its mouth at the San Jacinto River in eastern Harris County. Separate flood protection plans would be implemented for Carpenters, Greens, Halls, Hunting, Little White Oak, Brays, and Willow Waterhole bayous, and each plan could function independently. Recreation plans also would be developed independently for each area. Overall, the plans include stream enlargement and clearance, development of detention basins, acquisition of flood-prone property, construction of diversion dams, creation of diversion channels, and development of trails and other recreational facilities. Cost of the combined project is estimated at $541.2 million. Annual operation and maintenance costs are estimated at $1.8 million. POSITIVE IMPACTS: Implementation of the plan would provide flood control protection to the 1,034-square-mile area of southeastern Texas drained by Buffalo Bayou, providing protection to the 2.0 million residents of the Houston Metropolitan Area. Nearly 96,000 acres and more than 97,000 improvements, currently subject to flooding by the 100-year storm, would receive some or total protection from flooding. Average annual losses of $192.0 million due to flooding would be reduced substantially. NEGATIVE IMPACTS: Fish and wildlife habitat, particularly upland and riparian habitat, would be destroyed and disturbed by stream clearance. Acquisition of flood-prone property would be required.

Preparation date: September 14, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - U.S. ARMY MUNITIONS PRODUCTION BASE MODERNIZATION ACTIVITY'S RDX EXPANSION PROGRAM, LOUISIANA ARMY AMMUNITION PLANT, BOSSIER AND WEBSTER PARISHES, LOUISIANA. AN - 36405210; 1496 AB - PURPOSE: Construction and operation of a chemical/industrial complex at the Louisiana Army Ammunition Plant (LAAP) in Bossier and Webster parishes, Louisiana are proposed to manufacture Research Department Explosive/High Melt Explosive (RDX/HMX) and finished products. RDX, HMX, and other explosives used in many munitions are currently produced at the Holston Army Ammunition Plant near Kingsport, Tennessee. The Holston facilities, currently planned for modernization, are more than 40 years old and will not meet mobilization requirements. The Army initially screened 71 facilities for capability to support RDX and/or HMX production. Five sites across the nation were selected for sequential construction of production facilities, with LAAP selected as the lead plant. LAAP is a 15,000-acre plant in northwestern Louisiana that currently manufactures metal parts and assembles various munitions. The proposed production facility would have a capacity of 2.5 million pounds of RDX per month and other related finished products. The facility would require various manufacturing, processing, and storage buildings. Facilities requiring either modification or new construction would be used for administrative and support buildings, utilities, transportation systems, water supply, and wastewater treatment. POSITIVE IMPACTS: The primary beneficial impact of the proposed project would be economic, due to increased employment. Currently, the area has high unemployment. The three-year construction period would have an employment peak of approximately 600 jobs per year, while operation would require approximately 300 employees. According to most economic indicators, temporary influxes of money and associated employment would provide an economic stimulant of three to six percent to the Shreveport Standard Metropolitan Statistical Area. NEGATIVE IMPACTS: Potential environmentally adverse impacts identified include changes in air quality, additional water resource requirements during operation, water quality changes due to discharge of treated industrial wastewater, land use commitment of approximately 400 acres, and environmental hazards incidental to the manufacture, transport, use, storage, and disposal of toxic and/or hazardous materials and wastes.

Preparation date: September 11, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SAVANNAH HARBOR DEEPENING, CHATHAM COUNTY, GEORGIA. AN - 36412209; 1526 AB - PURPOSE: A plan for deepening Savannah Harbor in Chatham County, Georgia is proposed. Savannah Harbor is located along the first 21.3 miles of the Savannah River and has a current project inner harbor depth of 38 feet mean low water from its mouth to Kings Island Turning Basin. Under the preferred alternative, the channel would be deepened to an authorized depth of 40 feet between station 0.000 (river mile 0) and 103+000 (river mile 19.5). The bar channel would be deepened to an authorized depth of 40 feet between stations 0+000 and the end of the jetties (station 14+000B), then to 42 feet between 14+000B (2.65 miles oceanward of river mile 0) and 60+000B (11.4 miles oceanward of river mile 0). All new work dredged material from the interior channel would be placed in existing disposal areas. The new work is assumed to be sand and could be used to improve and increase the heights of the dike systems of the existing disposal areas, except for the Argyle/Hutchinson disposal area, where a road has been built to the disposal area so that the dredged maintenance material can be removed for use as road and general construction fill. New work material from the bar channel would be dredged and carried by hopper dredge to the ocean disposal site, a 4.26 square mile area centered at 31 degrees 56 minutes 54 seconds north, 80 degrees 45 minutes 34 seconds west. The plan assumes that all maintenance dredging for the present 38-foot channel would be completed prior to the new work dredging, including advance maintenance dredging where applicable. Total initial costs are estimated to be approximately $14.1 million. Annual costs would be $1.3 million, and annual benefits would be $1.6 million. Net annual benefits would be $296,700, with the overall benefit/cost ratio being 1.22 to 1.0. POSITIVE IMPACTS: Channel deepening would allow passage of larger vessels through the harbor at all tides, thus reducing shipping delays. The harbor modification would make Savannah Harbor more attractive for shipping interests and others, thus bringing in more business for Savannah, Chatham County, and Georgia. The deposition of new work in existing disposal areas would extend their lifetime capacities. NEGATIVE IMPACTS: Disposal of dredged material as proposed would not cause any new adverse environmental impacts, since existing disposal areas and dredging techniques currently being utilized in the harbor would continue to be used. Although dredging might affect the historic wreck of the CSS Georgia, impacts could be mitigated by mapping, recovery, and conservation of the wreckage on the channel bottom and the 100-foot stand-off restrictions to dredging in this area. Benthic communities in the area of channel deepening would be disturbed, especially where the channel has to be widened; most of the benthic population would be lost from the dredging. Minor salinity increases would occur, and new impacts to significant cultural resources could occur from the deepening.

AN - 36413298; 1524 AB - PURPOSE: Deepening and widening of the existing Oakland Harbor channels in the Port of Oakland, California is proposed. The port lies on the east side of San Francisco Bay, near the western terminus of major rail and highway networks. This supplement to the final environmental impact statements of September 1979 and November 1984 recommends a plan that would involve deepening navigation channels from 35 to 42 feet below mean lower low water between the entrance to the harbor via Bay Channel and Clay Street Piers and widening certain reaches of the channels to permit optimum use of restricted channel dimensions. Project dredging would occur over a 3.4 mile channel and an associated turning basin. Widening would take place in the shoal area on the north side of the inner harbor entrance reach and in other areas. The project would involve dredging approximately 2.8 million cubic yards (mcy) of material from the Oakland Outer Harbor Federal Channel and 3.7 mcy of material from the Oakland Inner Harbor via clamshell, hopper, and cutterhead dredges and transportation to the Alcatraz disposal site. Estimated cost of the project is $28.1 million, and the benefit-cost ratio is estimated at 7.0. POSITIVE IMPACTS: Enlargement of the channels would eliminate tidal delays for 75 percent of all container vessels projected to be in service by 1996. As a result, waterborne transportation costs associated with the port would decline significantly. Widening of the channel would reduce the risk of navigational accidents. Commercial shipping through the harbor would increase. Estimated annual savings resulting from the project would amount to $26.5 million. NEGATIVE IMPACTS: Deeper channels would trap more sediment, increasing the cost of maintenance. Widening of the channels would subject undisturbed benthic habitat to periodic disturbance. Dredging activities would create turbidity, temporarily lowering ambient water quality and possibly disturbing slightly the foraging habits of a nearby colony of the California least tern, an endangered species.

AN - 36412253; 1516 AB - PURPOSE: Construction of a transportation facility in the unconstructed Route 85 transportation corridor between Route 101 in south San Jose and Stevens Creek Boulevard/Route 280 in Cupertino, California, a distance of approximately 18 miles, is proposed by the California Department of Transportation (Caltrans). Additionally, the Guadalupe Corridor Project would be revised to provide a freeway facility, instead of the presently proposed expressway on Route 85 on the overlap section between the Route 87/85 interchange and Miyuki Drive. All interchanges, separations, bridge structures, retaining walls, sound walls, grading, and other design features would be designed as appropriate to accommodate future transportation options in the corridor. The proposed project would provide a freeway with six total lanes, consisting of four mixed-flow lanes and two commuter lanes for buses and high-occupancy vehicles (HOVs) occupied by two or more people. Commuter lanes would be used as such during peak hours only and would be used for mixed-flow through traffic at other times of the day. The median would be of sufficient width for future mass transportation. Seventeen interchanges would be provided. Rights-of-way acquisition and the construction of portions of the freeway to freeway interchanges (Routes 85/101, 85/87, 85/17, and 85/280) and all other interchanges would be provided as necessary to permit staged development based on available funding at the time of construction. All mitigation measures, such as noise attenuation, landscaping, and sequence of construction work, would be consistently applied throughout the corridor to minimize adverse impacts of the project. A bicycle plan would be developed for the corridor jurisdictions, and pedestrian facilities and on-site park-and-ride facilities would be considered. Ramp metering, with a county-wide traffic control center and bus and carpool bypass lanes, would be provided at all on-ramps. The cost of the project, including rights-of-way acquisition and construction, is projected to be $495 million. POSITIVE IMPACTS: The proposed plan would improve the existing transportation network. Emergency services would benefit by the creation of a new route by which emergency vehicles could travel in the corridor. The decrease in travel time between the residential portions of the valley and the commercial and industrial areas would encourage growth. NEGATIVE IMPACTS: Adverse impacts include floodplain encroachment, loss of wetlands and riparian habitat, noise increases, visual changes, impacts to historical structures, loss of parklands, relocation and/or displacement of residents and businesses, changes in traffic movements, relocation of existing utilities, and construction impacts such as noise, dust, and traffic congestion. Most of these impacts would be reduced through mitigation measures.

Preparation date: August 27, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED FLOOD REDUCTION PLAN FOR CATTARAUGUS CREEK, NEW YORK. AN - 36401827; 1490 AB - PURPOSE: A flood reduction plan for the Cattaraugus Creek Watershed located in Sunset Bay, New York at the mouth of Cattaraugus Creek is proposed. The preferred alternative consists of a 270-foot long ice-retention structure, a 200-foot wide adjacent floodway for passage of flood flows (overflow channel), a fish ladder with a fish-holding facility, and recreational fishing facilities just upstream of the town of Versailles (creek mile 11). The ice-retention structure would also have three gated, low-flow openings incorporated into its design to accommodate summertime flows. Further, a debris boom would be installed upstream of the ice-retention structure to trap debris before it becomes lodged against the structure. Operation of the plan would include closing the gated low-flow openings during the late fall and early winter ice-forming period for the purpose of forming a stable ice cover. The pool and stable ice cover would be maintained during the winter, until the end of June, in order to prevent ice from flowing down the creek and jamming at the creek mouth. In conjunction with the sea lamprey control barrier, it would severely hinder lamprey migration into the upper reaches of the creek during their spring spawning period. While the pool is being maintained, salmonids and other fish species would be able to continue upstream and downstream via the fish ladder. The bedload material trapped behind the ice-retention structure, estimated to be approximately 36,000 cubic yards per year, would be removed. Fisherman access features were also incorporated into the basic flood control plan. These features include a 15-car gravel parking lot, portable restroom facilities, and several gravel paths down to the creek. The construction cost of the project is presently estimated to be $1.5 million, with a benefit-to-cost ratio of 1.51. Environmental considerations include a summer and fall construction period, appropriate disposal methods, erosion and siltation protection measures, assorted revegetation, continual minimum stream flow, and health and safety measures. POSITIVE IMPACTS: Hazardous situations in the lower reaches of Cattaraugus Creek related to ice-jam flooding would be greatly reduced. Reduced flooding and associated damages could slightly increase property values. A substantial reduction in flooding would encourage stability and desirable growth in protected areas. Minor to moderate short- and long-term beneficial impacts would occur to community and regional growth, facilities and services, health and safety, and community cohesion. In the absence of a project to reduce flood damages in the project area, farmland may continue to be lost through erosion. Construction may provide employment to a small number of workers, and some increase in local businesses may occur. NEGATIVE IMPACTS: Minor to moderate short-term adverse impacts could occur to water quality, air quality, benthos, soils, public facilities and services, health and safety, property values and tax revenues, community cohesion, noise, and aesthetics. These are generally related to construction activities. Moderate long-term adverse impacts would occur to vegetation, wildlife, and fisheries.

Preparation date: August 19, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NORTH CAROLINA ROUTE 90 FROM TAYLORSVILLE TO I-40, ALEXANDER AND IREDELL COUNTIES, NORTH CAROLINA. AN - 36401369; 1480 AB - PURPOSE: Staged construction of a four-lane highway on new location in Alexander and Iredell counties, North Carolina is proposed. Two alternates are being considered. These alternates begin just north of the intersection of NC 90 and I-40 in Iredell County and terminate where the alternates intersect existing NC 90 just west of Taylorsville in Alexander County. Both alternates are located south of the present NC 90 for the entire length of the project. Alternate A is 18.43 miles long and Alternate B is 18.45 miles long. The two alternates are common for approximately 3.26 miles of the project length. The average annual daily traffic along the alternates is expected to range from 1,700 vehicles per day (vpd) to 5,500 vpd in 1987 and from 3,200 vpd to 9,300 vpd in 2007. A design speed of 70 miles per hour (mph) is proposed, which reflects the geometric design of the highway and provides for a margin of safety for vehicle operation. The posted speed limit, however, would be 55 mph. Although the proposed highway is a two-lane facility, rights-of-way would be required for an ultimate four-lane divided facility. Rights-of-way width is expected to be 300 feet, or as needed to contain construction. The proposed cross-section would consist of a 24-foot two-lane roadway with 12-foot shoulders. The shoulder width would include 2-foot paved shoulders. The future four-lane divided cross-section would consist of two 24-foot pavements separated by a 60-foot grass median. This median width would allow earthwork to be minimized during the design phase of the projects. The shoulder width on the four-lane cross-section also would be 12 feet, including 2-foot paved shoulders. It is not known when the additional lanes would be built. In addition, existing NC 90 from the I-40 interchange ramps to the proposed relocation would be widened to a 64-foot face-to-face five-lane curb-and-gutter section. The length of this five-lane section would be approximately .30 mile. Partial control of access is proposed, with access only at designated intersections. All intersections would be at-grade and stop sign controlled. No bridge structures would be required, as all drainage would be handled by pipes or culverts. Since staged construction is planned, the contract for the Taylorsville bypass portion of the project would probably be let at an earlier date than the remainder of the two projects. Cost estimates range from $34.7 million to $39.6 million. POSITIVE IMPACTS: The proposed action would provide improved traffic service between Statesville and Taylorsville and would serve to relieve congestion in Taylorsville by providing a bypass south of the town. The primary benefits would be increased safety, due to better alignment and partial control of access, and economic gains resulting from the improvement in highway transportation. The improved highway would result in fewer accidents and reductions in travel time, fuel consumption, and vehicle operating costs. NEGATIVE IMPACTS: Depending on the alternate selected, 33 to 42 homes and 3 businesses would be displaced. There would be an increase in the noise level in areas adjoining the project. An estimated 431 acres of prime and locally important farmland would be taken for rights-of-way. Some erosion, siltation, construction noise, and public inconvenience would result during construction. Some natural wildlife habitat would be removed and/or disturbed; an irretrievable commitment of approximately 140 acres of wildlife habitat would be made. Construction of the highway would also commit the state to provide operating, maintenance, and repair costs throughout the life of the facility.

Preparation date: August 19, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SOHARE CREEK UNIT EXPLORATORY OIL WELL NO. 1-35, PROPOSED OIL AND GAS DRILLING NEAR JACKSON, TETON COUNTY, WYOMING. AN - 36396023; 1458 AB - PURPOSE: The Amoco Production Company of Riverton, Wyoming proposes to drill and produce from an 11,050-foot exploratory oil well on the Jackson Ranger District, Bridger-Teton National Forest, in northwestern Wyoming, 45 miles northeast of Jackson. The drilling and production proposal, known as the Sohare Creek Unit Exploratory Oil Well No. 1-35, is located in the Sohare Creek drainage, a tributary to the Gros Ventre River in Teton County, Wyoming, in the SW 11/4 of Section 35, T43N, R112W. Access to the proposed site would use 18.6 miles of the existing Flagstaff and Leidy Creek roads south from U.S. Highway 26-287. An additional 3.3 miles of new road construction would be required in the Kettle Creek and upper Sohare Creek drainages. A worker campsite to house drilling-related personnel on location is planned. The camp would be designed to hold a maximum of 30 people and would be located adjacent to the drill site, in order to centralize the drilling operation, to reduce the total amount of site disturbance involved with construction, and to use the drilling rigs' electrical power source for the worker campsite service needs. Total area of disturbance, including the drill site, production facilities, campsite, and access road, would be approximately 26 acres. POSITIVE IMPACTS: The Bureau of Land Management's oil and gas leasing program is needed to encourage development of domestic oil and gas reserves to reduce the United States' dependence on foreign energy supplies. The proposed drilling action would result in major new road construction and reconstruction of existing roads. NEGATIVE IMPACTS: Drilling of the exploratory oil well would cause short-term and long-term disturbance to and displacement of the human and natural environments. Earthquakes could potentially affect access roads by triggering landslides and possible road subsidence. All roading alternatives under consideration would have segments of steep slopes that would be difficult to reclaim. Construction and operation of access roads within 500 feet of a stream could increase erosion and subsequent sedimentation in streams. Access roads crossing streams would also increase sedimentation through channel bed disruption and readjustment, thus degrading water quality. Contamination of surface water by spilled fuel or drilling fluid and contamination of freshwater aquifers by drilling fluids or mixing of groundwater could occur. Increased sediment loading in streams could in turn result in a reduction in fish populations or available habitat. Impacts to vegetation and range resources directly relate to the clearing and disturbance of vegetation due to drill site and access road construction. Forested stands would be disturbed, and timber resources would be lost. Unavoidable adverse impacts would occur to wildlife throughout the life of the proposed project. Visual impacts associated with drill site and access would be significant if the well is productive. The proposed action would require changes in current recreation classifications in portions of the project area. If fully implemented, proposed mitigation measures would avoid or reduce all impacts to water, fisheries, vegetation, and wildlife resources to insignificant levels.

Preparation date: August 11, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED FREEWAY CONNECTION FROM THE END OF ROUTE 23 AT NEW LOS ANGELES AVENUE TO THE END OF ROUTE 118, 0.3 MILE EAST OF COLLEGE VIEW AVENUE IN THE CITY OF MOORPARK, COUNTY OF VENTURA, CALIFORNIA. AN - 36401728; 1476 AB - PURPOSE: A freeway connection from the northern end of the Route 23 freeway to the west end of the Route 118 freeway in the city of Moorpark, county of Ventura, California is proposed. This connection between the two freeways would close an existing 2.2 mile gap in the freeway system. Three build alternatives are evaluated. Alternative 1(A): A single freeway roadway with ramps at Princeton Avenue. This alternative consists of a four-lane freeway connecting the existing freeways with interchanges at New Los Angeles Avenue, Princeton Avenue, and Collins Drive; an undercrossing at Los Angeles Avenue; a bridge over the Arroyo Simi; and an overhead over the Southern Pacific Railroad tracks. The cost is estimated at $31.3 million. Alternative 1(B): A single freeway roadway with ramps at Condor Drive. The geometrics for this alternative are the same as the previous alternative, except an interchange would be constructed at North Condor Drive Extension instead of at Princeton Avenue. The cost is estimated at $41.0 million. Alternative 1(C): A split freeway roadway with ramps at Princeton Avenue. This alternative would provide for a split roadway through the large curve connecting the two freeways. Local ramp service is proposed at Princeton Avenue. The cost is estimated at $34.8 million. POSITIVE IMPACTS: Closure of the gap between the two freeways would better serve the local and regional transportation needs by providing a high speed facility, relieving congestion on local streets, reducing the currently high accident rate, and providing a facility for existing and future transportation needs in the Route 118 and Route 23 corridors. Traffic volumes on the existing two-lane section of Los Angeles Avenue between Moorpark Road and Princeton Avenue would decrease by at least 80 percent. Most truck traffic currently using the section of local roadway would stay on the freeway. Air quality would improve. NEGATIVE IMPACTS: Approximately six acres of wetlands would be impacted by this project. The wetlands consist of freshwater marsh and riparian woodland and have been classified as habitat of high value for evaluation species. Noise levels would range between 59 and 63 dBA with the project, including the proposed soundwall mitigation. The bridges across the Southern Pacific Railroad, the Arroyo Simi, and Los Angeles Avenue would introduce a bold artificial element to the existing seminatural area. Depending on the alternative, between 60 and 150 oak trees would be removed, and the visual unity of the area would be affected.

Preparation date: August 10, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - JONESPORT HARBOR, MAINE NAVIGATION IMPROVEMENT PROJECT (ADOPTION OF THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1973 PREPARED BY THE ARMY CORPS OF ENGINEERS). AN - 36401061; 1489 AB - PURPOSE: The town of Jonesport, Maine has requested financial assistance from the Farmers Home Administration (FmHA) to fund a portion of the Jonesport Harbor Navigation Project, for which a final environmental impact statement was filed by the Army Corps of Engineers in August 1973. FmHA would monitor the construction, inspections, and expenditures. Jonesport Harbor is located on the north side of Moosabec Reach, approximately 190 miles northeast of Portland, Maine. Fishing is the only industry supporting the local population, although peat moss is harvested from local bogs for shipment throughout the country. The project would consist of dredging an entrance channel 100 feet wide and 8 feet deep, leading from deep water in Moosabec Reach into Sawyer Cove, and two anchorage areas, one composed of 9 acres, 6 feet deep, and the other composed of 6 acres, 8 feet deep. It would also require construction of a 1,500 foot combination rubble mound and steel cellular breakwater. Approximately 90,000 cubic yards (cy) of soft material would have to be removed for the breakwater foundation, and dredging for the entrance channel and anchorage areas would require removal of an additional 57,000 cy of this material. Dredged material would be disposed in a deep water offshore area, provided it is not too polluted for offshore spoil disposal. POSITIVE IMPACTS: Jonesport's economy is restricted by the lack of protected anchorage and the scattering of support shore facilities. These factors would be eliminated by taking advantage of the favorable topography of Sawyer Cove and establishing it as the center for Jonesport's fishing activities. The breakwater would afford protection to the local fishing fleet from all storm waves approaching through Moosabec Reach from the east and southeast, with the exception of hurricanes. It would reduce damage to boats, moorings, and lobster cars by centering activities of the fishing fleet in Sawyer Cove. The construction of a public landing would eliminate the need for individual owners to maintain wharves along the open shore of the reach. The public wharf would enhance the harbor, since greater effort could be expended on maintaining a single general-purpose wharf rather than on maintaining minimal fish-handling facilities on the exposed piers scattered along the main waterfront. NEGATIVE IMPACTS: No major adverse effects are anticipated. The breakwater would occupy a small area of bottom habitat and would create minor changes in circulation patterns within the cove. There would be some temporary increase in turbidity during construction operations. Aesthetics would be impaired by the sheet steel pile breakwater set against the rocky forested coastline. The channel and anchorages would increase boat activity in the cove, causing spilling and leakage of gasoline and oil and discarding of unwanted species or bait from lobster boats and other vessels.

AN - 36387990; 1488 AB - PURPOSE: This supplemental environmental impact statement (SEIS) examines the environmental impacts associated with the barrier features of the New Orleans to Venice, Louisiana Hurricane Protection project. It evaluates an environmentally preferable and less costly alternative to the barrier plan presented in the original final environmental impact statement. Of the three plans evaluated, the West-bank River Levee (WBRL) alternative is the Tentatively Selected Plan. It involves an enlargement of the existing Mississippi River and Tributaries (MR&T) levee to hurricane grade from City Price to Venice, Louisiana. This represents an increase of grade of approximately six inches in the upper sections to a three-foot increase in the lower portions. A O- to 120-foot uncompacted fill stability berm would be constructed landside of the levee, where required, and a 45- to 55-foot uncompacted fill wave berm would be constructed throughout the project on the river side of the levee. This wave berm would be armored with approximately 100,000 cubic yards (cy) of shell and 500,000 tons of riprap. In reaches where stability conditions do not permit an enlarged levee, a levee setback or floodwall is proposed. The levee and associated berms would be constructed with approximately 6.2 million cy of fill. To obtain the necessary fill, approximately 19 million cy of material would have to be removed from some 800 acres of batture area on the east side of the river. In areas where the west-side batture exceeds 200 feet, a 60-foot-wide flotation channel would be constructed adjacent to and riverside of the levee to allow the placement of fill material. Material removed from the channel would be placed in the berm or levee. Operation and maintenance would consist of grass mowing; levee road repair; and rock, shell, and other armor replacement. The first cost of this plan would be about $84 million. The total project cost is estimated at approximately $255 million, with a benefit-to-cost ratio of 1.7. POSITIVE IMPACTS: The project would provide protection from hurricanes and flooding, reduce hazards to life and property, protect existing lands from further loss, and enhance their current use. NEGATIVE IMPACTS: The proposed plan would result in the loss of 772 acres of batture woodlands and 13 acres of remnant, enclosed levee forest. It would temporarily disrupt 237 acres of clear, developed land, 453 acres of existing levee, and 581 acres of Mississippi River bottoms. Because of the extensive wetlands in the project area, there would be no practicable alternatives to locating some project features of the recommended plan in these areas. Most of the sensitive levee forest sites within the proposed borrow sites were deleted during the planning process. Most of the batture woodlands are pure willow stands. Significant environmental impacts would be mitigated.

Preparation date: August 7, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SAN JACINTO RIVER AND TRIBUTARIES, TEXAS FLOOD DAMAGE PREVENTION: INTERIM REPORT ON CYPRESS CREEK AND SUPPLEMENTAL REPORT DATED AUGUST 1986. AN - 36406364; 1493 AB - PURPOSE: A flood control project for the Cypress Creek watershed, located in southeastern Texas approximately 10 miles northwest of Houston is proposed. The creek is 54 miles long and drains a 320-square-mile area in northern Harris and eastern Waller counties. It is a major drainage area in the San Jacinto River basin. The recommended plan consists of channel modification, recreation facilities, and fish and wildlife mitigation measures. A 29.4-mile-long channel would be constructed from the mouth of Cypress Creek upstream to U.S. 290. Work would involve widening, deepening, and straightening the existing channel and construction of a trapezoidal channel. The channel would vary in bottom width from 200 feet in downstream reaches to 30 feet near U.S. 290, the depth would be approximately 20 feet, and the top of its banks would be 2 to 3 feet above existing ground. Top widths would vary from 150 to 300 feet. The channel would have an earth bottom, with grass erosion protection on side slopes above the normal water surface, except for a 0.3-mile reach near the Interstate Highway 45 bridge, where it would have riprap-lined bottom and side slopes. Native trees, grasses, and shrubs would be planted in the project rights-of-way. Six highway bridges would be replaced, one highway bridge would be extended, 28 pipelines would be relocated, and 25 single-family residences would be purchased and removed. Recreation facilities would include 11.5 miles of lighted hiking and biking trails, with six foot bridges, at seven existing Harris County parks; seven parking and public access areas with restrooms; and two canoe launching ramps. Fish and wildlife mitigation measures include habitat improvements on 70 acres of project lands, 844 acres of Harris County parklands, and 329 acres of private lands located along Cypress Creek. Based on October 1986 price levels, the estimated first cost of the recommended plan is $111.5 million, and the benefit-cost ratio is 1.2. Average annual benefits for flood damages prevented and recreation are estimated at $15.1 million, and the benefit-cost ratio is 1.5. POSITIVE IMPACTS: The recommended channel would prevent flooding on approximately 4,200 acres of land within the existing 100-year floodplain, protecting more than 1,300 structures, most of which are residential. The recreational plan would partially fulfill the needs for additional recreational facilities for outdoor leisure activities. Trails and canoe launching ramps would enhance recreation opportunities and improve the general well-being of people in the area. The recommended plan would reduce financial losses, health hazards, and the risk to human life and safety associated with existing and future flood problems. NEGATIVE IMPACTS: Channelization would result in a loss of many cypress ponds and meanders and a shortening of the channel length by approximately 3.8 miles. Significant habitat losses would include 303 acres of mixed woods, 47 acres of riparian woods, and 54 acres of aquatic habitat. Due to anticipated future development in the watershed, although the plan would initially provide flood protection against a 40-year-frequency flood, the protection would decrease to a 10-year-frequency level. Fish and aquatic invertebrate populations would suffer severe reductions; however, these would be offset by proposed mitigation measures. Wooded habitat would be destroyed and separated from the stream, resulting in loss of habitat for numerous species. Construction activities would cause temporary, but significant, turbidity.

Preparation date: August 3, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SACRAMENTO RIVER BANK PROTECTION PROJECT (BUTTE BASIN REACH), CALIFORNIA (DRAFT SUPPLEMENT IV TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1973). AN - 36395509; 1484 AB - PURPOSE: Protection of levees of the Sacramento River Bank Protection Project (SRBPP) from erosion along the Sacramento River between river miles (RM) 0 and 194, including the Delta sloughs of the Sacramento River, the Yolo Bypass, the Colusa Basin Drainage Canal, and the lower Feather River in Solano, Sacramento, Yolo, Sutter, Colusa, Glenn, and Butte counties, California is proposed. This fourth supplement to the final environmental impact statement (FEIS) describes the impacts of the remaining congressionally authorized bank protection of up to 132,000 lineal feet along the Sacramento River system as far north as Chico Landing. A method to implement the programmatic analysis at future work sites is provided, the cumulative impact of all previous SRBPP work is described, and outstanding impact mitigation requirements are established. Bank protection work may occur at more than 100 tentatively identified sites during the period 1988 to 1991, although actual construction sites will not be finalized until the winter before construction. Selection of an appropriate bank protection method for an erosion site must be site-specific, depending on several considerations. Bank protection methods for possible future use in the SRBPP fall into two general categories: (1) armoring with riprap, which enables the bank to withstand the erosive forces of flows or waves; and (2) flow modification, which directs the erosive forces away from the bank. Several riprap configurations have been utilized, and others may be feasible. Flow modification methods are being studied experimentally upstream on the Sacramento River. The preferred alternative would result in the use of various configurations and heights of riprap. The preferred bank protection method for any given site would be the feasible riprap configuration and height that is environmentally superior. Currently, experimental methods such as flow modification and vegetation in revetment will not be considered feasible until efficacy is proved, and they are not included in the preferred alternative. Feasibility will be determined on a site-specific basis, based on relevant site considerations, including consideration of assured provisions for long-term maintenance. Avoidance of significant resources, or mitigation where impacts are unavoidable, will be used to assure no net loss of woody riparian and shaded aquatic habitat value. Where more than one method /mitigation combination is available, preference would be given to maintaining or restoring the linear continuity of riparian habitat along the waterways. The total estimated cost is $20 million to $25 million; annual maintenance costs are estimated at $40,000 to $50,000. POSITIVE IMPACTS: Under all scenarios, the proposed project would increase the proportion of the Sacramento River bank protected under the SRBPP from approximately 35 percent to 41 percent, although bank protection would occur at sites with widely differing amounts of bank protection in the vicinity. Reliability would be optimized by using methods requiring the least maintenance. The effect in the sloughs was not estimated, but is probably similar. NEGATIVE IMPACTS: Negative impacts can only be estimated, but might include the loss of 72 percent of woody riparian habitat, 11 miles of shaded aquatic habitat, and any special-status plant, bird, and insect communities found at work sites. Chinoock salmon rearing habitat also would be lost at most work sites. Continuing use of mitigation recommendations would reduce the cumulative impacts to less-than-significant levels.

Preparation date: August 3, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ROCK CREEK/MUDDY CREEK RESERVOIR, ROUTT AND GRAND COUNTIES, COLORADO. AN - 36395499; 1525 AB - PURPOSE: Construction of two water storage reservoirs in Routt and Grand counties in western Colorado are proposed. The alternatives are Rock Creek Reservoir in the Routt National Forest and Muddy Creek Reservoir in the Kremmling Resource Area. The proposed interim operation of the project involves the lease of a major portion of the reservoir yield to the Denver Water Board for 25 years. The Rock Creek site is the applicant's proposed action and is located just south of State Highway 134 west of Gore Pass, where Rock Creek enters a narrow valley. The Rock Creek Dam is proposed to be a roller compacted concrete (RCC) gravity dam, that would rise 172 feet above the existing streambed and impound 50,700 acre-feet of water. The Muddy Creek alternative was sized to be functionally equivalent to the Rock Creek project, with the site located just west of Wolford Mountain (five miles north of Kremmling, Colorado). The Muddy Creek Dam would be a zoned earthfill dam with a dam crest located 110 feet above the present streambed. It would create a 46,800 acre-foot capacity reservoir. The alternatives considered are similar in terms of costs, operations, and yields. The differences between the alternatives relate to socioeconomic effects, environmental impacts, and the projected effectiveness of mitigating these impacts. Total project cost of Rock Creek is estimated at $17.9 million; total project cost of Muddy Creek is estimated at $19.5 million. Due to the lease with Denver, the cost /benefit value is 2.5 for the reservoir. POSITIVE IMPACTS: Beneficial impacts of both alternatives include increased recreational use of the reservoirs and associated campgrounds, reservoir fish habitat, and the economic benefits of the recreational use. Muddy Creek would also create a potential benefit in a cold water trout fishery in the tailwater of the dam. Hired labor would consist of 487 man-months in the first year and 485 man-months in the second year. NEGATIVE IMPACTS: The Rock Creek alternative would cause significant adverse impacts to wetlands, stream fish habitat, big game habitat (elk and deer), visual resources, and stream recreation, and could cause social conflict between different user groups. Mitigation would alleviate most of the impacts to wetlands and some of the impacts to fish and wildlife habitat. The Muddy Creek alternative would also impact wetlands, a candidate federal rare plant, big game habitat (elk and deer), and visual resources. Mitigation would alleviate the wetland and wildlife impacts and most of the rare plant and visual impacts.

The increased speed, memory and storage capacity of the latest PCs make the use of these large FORTRAM programs highly practical in the PC environment. Typical tasks that are required when using these batch oriented programs include creating, checking and editing input data; executing the program; and summarizing and displaying the results. HEC has developed a menu driven user interface or shell program to integrate several application programs, and editor and other utility programs to assist the user in accomplishing these tasks. The interface takes advantage of the unique capabilities and user friendliness found in the PC environment. In addition to the HEC-1 and HEC-2 programs, the integrated package includes a program (SUMPO) for creating summary tables of HEC-2 results, a program (PLOT2) that plots cross section and water surface profiles, and a PC version of the Corps of Engineers Editor (COED), which features full screen editing and on-line help screens and documentation. The application of these programs is described and demonstrated using the menu driven interface. JF - Technical Papers.

AN - 36400849; 1485 AB - PURPOSE: Permanent designation of a Charlotte Harbor, Florida ocean-dredged material disposal site (ODMDS) is proposed. The preferred site overlies the existing interim site located approximately four nautical miles (7.4 kilometers) west of Cayo Costa and six nautical miles (11.1 kilometers) southwest of Boca Grande Pass. The purpose of the action is to recommend an environmentally acceptable location for the ocean disposal of dredged materials. The current site has been in use on an interim basis since 1978. Recent site surveys detected no significant adverse effects to the water or sediment quality or cumulative changes in the biota that would be attributed to previous dumping. Sediment texture and sediment concentrations of trace metals and organics were characteristic of uncontaminated nearshore sediments. POSITIVE IMPACTS: The site would provide an environmentally acceptable location for the ocean disposal of dredged materials from Charlotte Harbor channel systems. NEGATIVE IMPACTS: Temporary, short-term environmental impacts would include smothering of benthos and increases above the ambient turbidity and sedimentation levels within the proposed site during disposal operations.

Preparation date: July 30, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CLAYTON (SARDIS) LAKE PROJECT, DAISY TO SARDIS LAKE ACCESS ROAD, JACKFORK CREEK, OKLAHOMA (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF FEBRUARY 1974). AN - 36402273; 1481 AB - PURPOSE: This final supplement evaluates the effects of constructing an access road, which would proceed easterly from the Indian Nations Turnpike at Daisy, in Atoka County, through Pittsburgh County to connect with State Highway 2 near the Sardis Dam (formerly named the Clayton Dam) and the town of Clayton, in Pushmataha County, Oklahoma. The travel distance between the two points would be 23.6 miles, shortening the old road some 4.0 miles on completion of all segments of the new highway. The new road would follow the alignment laid out by the state in 1963. New construction would begin near Daisy, approximately one mile east of the Indian Nations Turnpike and Oklahoma Highway 43 interchange. From this point, proposed relocation of Highway 43 would consist of approximately 16.6 miles of grading, drainage, and surfacing. The Stage I P-6 segment of construction, already completed, consists of minor reshaping of an existing roadbed to obtain a 32-foot-wide compacted subgrade. An 8-inch-thick aggregate base course, 24-feet wide, was placed and surfaced with 2-inch-thick asphaltic concrete 22-feet wide. Construction was completed with the addition of two 4-foot-wide turfed shoulders. The remainder of Stage I construction consisted of light grading along an old roadway connecting segments P-6 and P-3 to obtain a 32-foot-wide subgrade, replacing two minor drainage structures, and surfacing to match the P-6 segment. Stage II construction would begin on existing Oklahoma Highway 43 near the town of Daisy and run easterly to connect with the Stage I construction. A short segment of new roadway, designated P-3 extension, is also included in this stage. Proper signing, striping, connecting ramps, fencing, detours, and erosion control would also be part of the Stage II construction. Mitigation features to offset fish and wildlife losses include: (1) creation of bottomland forest on 14 acres of floodplain soils; (2) intensified management of 281 acres of upland forest on Sardis project lands; (3) planting the rights-of-way with a native grass-legume-wildflower seed mixture; (4) reclaiming borrow areas; and (5) an environmental monitoring plan to ensure that mitigation measures are successfully implemented. Enabling legislation requires that the state accept ownership and operate and maintain the completed facility. The estimated construction cost is $10 million. POSITIVE IMPACTS: The new road would greatly reduce the time needed for trips from the Indian Nations Turnpike and areas from the west to reach Sardis Lake. Construction of the road would most likely enhance growth and development in the project area in the form of residential and highway service businesses. NEGATIVE IMPACTS: Construction of the project would require displacement of people and removal of lands from private ownership. An additional 240 acres of rights-of-way would be needed to construct the proposed project. The most significant impacts would be the direct loss of 20 acres of stream bank vegetation, primarily bottomland forest. Cut and fill operations would create an unvegetated strip across the drainages, removing an additional 137 acres of upland forest and 80 acres of grassland. Until the newly constructed areas are revegetated, exposure to natural elements would create erosion, resulting in a major source of water pollution. The aquatic ecosystem of the streams crossed by the road would be subjected to direct, short-term impacts of construction. Wetlands impacted by the new road would include six ponds and three streams of the temporarily flooded palustrine broadleaved forest type and one stream of the seasonally flooded type. The long-term impacts would be loss of high quality habitat, resulting in a displacement of the wildlife communities. The highway would also act as a barrier to wildlife trying to move from one side of the road to the other.

Preparation date: July 28, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SACRAMENTO RIVER BANK PROTECTION PROJECT (BUTTE BASIN REACH), CALIFORNIA (DRAFT SUPPLEMENT III TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1973). AN - 36401700; 1483 AB - PURPOSE: Bank protection in the Butte Reach of the Sacramento River, from Collinsville to the vicinity of Chico, California, is proposed. The preferred alternative includes the construction of 13,700 feet of additional bank protection, a 50-percent reduction in the amount of rock bank protection formerly planned in this reach. The work involves the construction of two new bank protection sites and extensions to three existing sites, using the palisades construction method. Construction includes clearing, stripping, excavation, slope preparation, and placement of stone. At each site, a strip of land approximately 50 feet wide adjacent to, and parallel with, the existing bank is to be cleared for construction. Approximately 30 feet of this strip consists of temporary construction and maintenance access easements. Clearing would remove all vegetation, debris, and other material from the ground surface, including underwater areas. Combustible debris from cleared areas would be burned, and noncombustible materials would be disposed of offsite. Dust would be controlled through sprinkling. Following removal of vegetation, each site would be excavated or filled to the desired slope, and a 5-foot-wide toe trench would be excavated below the lowest part of the riverbed at the bottom of the slope. Excavated materials would be placed along the top of the bank or used as fill material. Excess material excavated from the river and bank slopes would be placed in designated upland disposal areas. A layer of quarry rock would be placed in the toe trench and on the bank slope. A 30-foot-wide easement area would be located adjacent to the rock bank protection and would be used primarily for four operation and maintenance activities: periodic inspections, damage repair, flood fighting, and appropriate vegetation removal. To facilitate continuing inspection of these areas, permanent access roads leading to the sites would be maintained. It is estimated that minor repairs will be needed following floodflows occurring on a 10-year interval and major repairs following floodflows occurring once in 50 years. Vegetation would be removed only as necessary to allow access by repair equipment. POSITIVE IMPACTS: The project would preserve desirable flood control conditions by preventing flows in excess of design capacity from entering the leveed reach of the river and ensuring the diversion of sufficient floodflows into the Butte Basin overflow area. NEGATIVE IMPACTS: Approximately 12 acres of riparian vegetation would be removed during project construction, and the formation of approximately 79 acres of riparian vegetation would be prevented over the 50-year period of analysis. This significant impact, however, would be mitigated to a desired level. The project could potentially jeopardize the continued existence of the threatened valley elderberry longhorn beetle and adversely impact other federally protected species, but mitigation would reduce these impacts to insignificance. Juvenile salmon rearing habitat would be reduced by converting naturally eroding banks to rock riprap areas. The visual aesthetics and the wild and scenic river potential of this reach of the river would be modified and/or adversely impacted.

Preparation date: July 27, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MINGO CREEK FLOOD PROTECTION PLAN, TULSA, OKLAHOMA (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1980). AN - 36387531; 1492 AB - PURPOSE: This report reviews the reevaluation of the Mingo Creek project, discusses alternatives, and incorporates modifications into the selected plan. Since the final environmental impact statement was filed, many segments of Mingo Creek and its tributaries have been channelized by the city of Tulsa. The city has also constructed detention sites, riprapped banks, and cleared several areas in residential neighborhoods. The Mingo Creek watershed is a portion of the Verdigris River basin. Mingo Creek flows from south to north through the eastern part of Tulsa, Oklahoma. The watershed occupies 61 square miles, and the designated project area contains approximately 22,000 acres. The study area is primarily urbanized, with approximately 17,546 acres of developed residential and commercial lands, 394 acres of woodlands, 4,013 acres of grasslands, and 74 acres of permanent water. The lower portion of the floodplain is mostly undeveloped, but the city of Tulsa is continually expanding throughout the watershed. Extensive pollution and siltation have degraded the quality of all the aquatic habitat, and further reduction is expected with or without the project. A total of 110 interacting sites were considered for the Mingo Creek project. All plans involve the use of detention sites and channel improvements and all require the disposal of excess excavated material. Previously disturbed grassland areas around the watershed would be used as disposal sites. The proposed plan would consist of a system of 23 floodwater detention sites and approximately 7.5 miles of improved channel on the main stem and tributaries of Mingo Creek. The detention sites would consist of 1 embankment site and 22 excavated sites. The embankment site would have a permanent pool of approximately 100 acre-feet and a maximum depth of 7 feet. The excavated detention sites range in size from 4 to 82 acres and would average 10.5 feet in depth. The sites would be dry most of the time. Floodwaters would enter the sites on the average of once every 5 to 7 years and would be retained from 24 to 48 hours. The sites would then completely drain and could be used for recreation and open space. Two portions of the main stem would be channelized with the plan. A 6,200-foot-long grass-lined channel would be built from Tulsa's completed channel at 11th Street upstream through Skelly Drive (I-44 bridge). The 21st Street North bridge would be replaced with a longer bridge. Some 4,800 feet of unlined channel would be constructed through the limestone restriction near 36th Street North and extend from 1,600 feet south of the bridge to approximately where 40th Street North would be. This bridge would be raised and extended for the new channel. Four tributaries would be channelized, generally following the existing channel alignments. Highway bridges would have to be modified or replaced. Approximately 6.8 million cubic yards (mcy) of earth and rock would be excavated for the detention sites and improved channels, of which approximately 1 mcy would be disposed of around the detention sites. The estimated first cost of the plan is $131.2 million, with an annual cost of $13.5 million. Average annual benefits are estimated at $30.3 million; the benefit-to-cost ratio would be 2.2. POSITIVE IMPACTS: The detention structures and channel work would protect 2,200 acres of urban land from a 100-year flood. The plan would preserve 591 acres of open space and greenbelt areas and establish or preserve 90 acres of bottomland timber. NEGATIVE IMPACTS: Over the life of the project, riparian woodlands in the project area would decrease from 1,432 acres to 88 acres. Grassland acreage would decrease from 8,771 acres to 705 acres, and developed acreage would increase from 11,775 acres to 21,239 acres. The 161 acres of aquatic habitat would decrease to 43 acres without the project and to 57 acres with the project. Loss and degradation of existing fish and wildlife habitat would result.

Preparation date: July 24, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MISSISSIPPI RIVER, BATON ROUGE TO THE GULF, PLAQUEMINES PARISH, LOUISIANA (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1974). AN - 36402317; 1487 AB - PURPOSE: Maintenance dredging of navigation channels to specified dimensions in the Mississippi River and in various passes from Baton Rouge, Louisiana to deep water in the Gulf of Mexico is proposed. The project would begin at the port of Baton Rouge, approximately 128.6 miles above the port of New Orleans, and would continue downstream to a point approximately 94.5 miles below New Orleans in the Head of Passes. Below Head of Passes (BHP), two channels, 22 miles and 14.5 miles in length, would connect the river channel to the Gulf of Mexico. These distances would include the bar channels for each pass. The project would provide maintenance dredging at eight crossings in the Mississippi River, New Orleans Harbor, South and Southwest passes, and bar channels; maintenance of regulating and contracting works at the Head of Passes and in South and Southwest passes, including 262 permeable pile dikes, maintenance of regulating and contracting works and of controlling outlets below New Orleans; and maintenance of jetty systems at the seaward ends of the South and Southwest passes. Channel dimensions would vary from 30 to 40 feet in depth and from 500 to 1,500 feet in width. This supplemental information report has been prepared to provide engineering and environmental information about the maintenance of two flow-regulating structures in the Mississippi River below Venice, Louisiana that are proposed for construction. The first of these structures concerns the W-2 controlled outlet dikes, the width of which would be maintained at Mile 9.8 BHP within Southwest Pass. The proposed maintenance work consists of the placement of 10,500 cubic yards of shell, 60,000 tons of graded stone, and 5,000 tons of filter stone along the existing alignment, with the upstream end connecting with an existing dike and the downstream end connecting with the river bank. All work would be performed within the river. A flotation channel, adjacent to the work sites, would be required for construction of the upstream and downstream connections. Excavated material (9,000 cubic yards) would be deposited a minimum of 20 feet riverward of the flotation channel. A total of approximately eight acres of river bottom would be covered or excavated as part of this maintenance work. The second structure, the East Headland Dike, protects the land between Pass a Loutre and South Pass and also controls the distribution of flow between these two passes. All maintenance work would be performed within the river, and no excavation would be necessary. The proposed work consists of placing 66,000 tons of graded stone along the existing dike alignment and along the South Pass and Pass a Loutre banks of the headland. A total of 530 creosoted timber piles (90 feet long) would be driven to reconstruct the deflection dike in Pass a Loutre. A total of approximately two acres of river bottom would be covered as part of headland dike maintenance. POSITIVE IMPACTS: Maintenance of the channels would allow access to the ports of New Orleans and Baton Rouge by oceangoing ships. With the recommended project features in place, annual dredging quantities would be reduced. The project would facilitate the continued growth of New Orleans, Baton Rouge, and the river region as a whole. Preservation of freshwater outlets would benefit the Delta National Wildlife Refuge, and creation of marsh areas would increase food supplies for endangered and threatened species. NEGATIVE IMPACTS: Dredging would increase turbidity, displace benthic fauna, and require placement of excavated materials on land along the South and Southwest passes, destroying vegetation that serves as wildlife cover. Construction activities would temporarily increase noise and air pollution levels.

Preparation date: July 23, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DES MOINES RECREATIONAL RIVER AND GREENBELT, DES MOINES RIVER, IOWA. AN - 36395345; 1473 AB - PURPOSE: Development, operation, and maintenance of a recreation and greenbelt area on and along the Des Moines River in Des Moines, Iowa, between the point at which the river is intersected by U.S. Highway 20 at Fort Dodge to the point downstream at which relocated State Highway 92 intersects the Des Moines River below the Red Rock Dam, are proposed. The project would include, but not be limited to: (1) the construction, operation, and maintenance of recreational facilities and streambank stabilization structures; (2) the operation and maintenance of this project (other than any such structure operated and maintained by any person under a permit or agreement with the Secretary of the Army) within the area; (3) such tree plantings, trails, vegetation, and wildlife protection and development and other activities as would enhance the natural environment for recreational purposes; and (4) the prohibition or limitation of the killing, wounding, or capturing at any time of any wild bird or animal. Nineteen of the originally proposed 121 projects were eliminated from further study. Of the remaining 102 projects, 4 involve development of trails or scenic routes, 21 propose land acquisition and/or environmental enhancement measures, 7 involve streambank stabilization, and 70 involve development or improvement of various aquatic or terrestrial recreation facilities. Site plans, preliminary cost estimates, and general evaluation of potential environmental and social impacts have been developed for each of these projects. The General Design Memorandum (GDM) does not contain site plans developed in sufficient detail to permit a detailed analysis of environmental, social, or economic impacts. Prior to construction of any greenbelt projects, a site-specific environmental assessment would be prepared for public and agency review. Formulation of site and design alternatives for projects involving development or modification of terrestrial and aquatic areas would attempt to maximize this potential while minimizing the potential for adverse effects from construction, operation, and maintenance of facilities. POSITIVE IMPACTS: Several of the identified projects located in the city of Des Moines could result in a noticeable improvement in scenic or other aesthetic values within the downtown area and in parts of recreation areas. Recreation projects located in or near urban areas could have some minor effect on actual or potential community growth. Several of the identified projects could indirectly increase property values in surrounding areas by providing recreational opportunities that could add to the economic potential of the area or enhance its attractiveness to prospective buyers. Completed recreation projects would enhance local, and in some cases regional, recreational opportunities while alleviating some of the demands on existing facilities. Construction could cause a short-term increase in employment and business activity. Several projects would be beneficial for protection, interpretation, or enhancement of historic properties. Projects that increase vegetative cover or stabilize streambanks could result in some improvement in water quality by reducing soil erosion. NEGATIVE IMPACTS: Some acquisition of farmland may be required for environmental enhancement projects or as rights-of-way for trails and other recreation projects. Several projects could result in the loss of bottomland forest habitat or alter the existing water quality and habitat value of portions of the Des Moines River. Several construction projects would result in adverse effects to significant historic properties. Loss of tax revenues could result from implementation of projects involving public acquisition of private lands.

Preparation date: July 23, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - APOLLO HICKORY CORRIDOR, FROM APOLLO 11 BOULEVARD AT U.S. 1 TO AURORA ROAD AT U.S. 1, BREVARD COUNTY, FLORIDA. AN - 36404175; 1432 AB - PURPOSE: Construction of a multilane arterial roadway from the intersection of U.S. 1 and Apollo 11 Boulevard in the city of Palm Bay, north to the intersection of U.S. 1 and Aurora Road in the city of Melbourne, Brevard County, Florida, a total corridor length of approximately 8.0 miles, is proposed. The proposed route uses portions of existing rights-of-way and requires some new rights-of-way. In addition, two new major bridge structures would be required, one crossing Crane Creek and the other crossing the Eau Gallie River. The build alternative considered within the Apollo Hickory corridor involves two alternate alignments south of Florida Avenue and two alternate alignments along South Hickory Street. Alternate B1-C would use some existing road rights-of-way, while alternate segment B-C would be built entirely on new rights-of-way. Along South Hickory Street, alternate segment D1-E1 would displace homes along the east side, while alternate segment D-E would displace an existing canal. The recommended design speed is 45 miles per hour. Major signalized intersections would occur at 12 locations. POSITIVE IMPACTS: The proposed project would improve regional access and alleviate growing vehicular congestion. Road users would benefit from the improved levels of service and safety. Air quality would improve as vehicles achieve more efficient operating speeds. NEGATIVE IMPACTS: The proposed highway facility would increase noise levels adjacent to its alignment. Of the 10 noise sensitive sites analyzed, noise levels at 6 sites would be increased above the accepted noise levels. Air pollutant concentrations would increase slightly along the proposed alignment; however, levels would be less than state and federal standards. Current design standards for highways of this type would remove or disturb some natural vegetation and would impact some wetlands, mainly around the bridge crossings. The roadway would require relocation of residences and businesses throughout the entire corridor, with residential displacements totalling 26 to 33 and business displacements totalling 11 to 12. Alternate segment B-C would not require any displacements; alternate segment B1-C would displace one business; alternate segment D1-E1, while avoiding the impact on 1.61 acres of wetlands associated with an existing canal, would cause seven more relocations than alternate segment D-E, including the Greater Faith Temple of God in Christ Church. Some land presently in natural cover would be modified by the placement of embankment material, pavement of roadway, and the construction of bridges, involving the clearing of vegetation. The construction of roadway surfaces would reduce the amount of permeable area available for the percolation of water to the aquifers.

Preparation date: July 10, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CALIENTE CREEK STREAM GROUP INVESTIGATION, KERN COUNTY, CALIFORNIA. AN - 36404431; 1442 AB - PURPOSE: Water resource-related problems in the Caliente Creek Stream Group in Kern County, California were investigated, and a plan for flood control was proposed. The preferred alternative would feature a 16,000-acre-foot flood detention basin. Major features of the plan include an earthfill embankment, a combination diversion/spillway channel, and an ungated cut-and-cover outlet works. The dam and combination diversion/spillway channel would be designed so that all flows from Caliente Creek would enter into the reservoir. As the reservoir fills, flows would back up into the diversion /spillway channel and spill over the downslope bank of the channel. The dam would have a maximum height of 78 feet. The upstream slope would be 1 vertical (V) on 4 horizontal (H), and the downstream slope would be 1 V on 2.5 H. The upstream bank of the embankment would be protected from wavewash by a 12-inch layer of riprap over a 9-inch filter layer. At gross pool elevation (701.0 feet), the reservoir would have a surface area of approximately 515 acres, a length of approximately 1 mile, and a maximum depth of 61 feet. The proposed dam would be an earthfill structure approximately 1.8 miles long, with a maximum height of approximately 80 feet. The zoned embankment would include an impervious core with stone protection on the upstream slope and a clay blanket on the downstream slope. The emergency spillway would be located just east of the dam embankment. As the reservoir fills, flows would back up into the spillway approach channel and spill over the ungated control sill into the spillway return channel. The control sill would be 2,600 feet long. The outlet works located at Station 31+50 of the dam would consist of an ungated inlet structure with a trash rack, a 4.5-foot diameter conduit 387 feet long, and an impact stilling basin at the downstream toe of the dam. The outlet would have a maximum capacity of 500 cubic feet per second (cfs) at gross pool. The impact basin would connect with a diversion structure that would divide flows equally into the two downstream channel improvements. The two channels would each be approximately 17.5 miles long and have a capacity of 250 cfs. The channels would be trapezoidal unlined earth or grass without levees. The excess excavation material would be a reinforced concrete conduit under Panama Road. At the downstream terminus, the remaining flood water would be diverted into the Kern Lake Bed area by existing channels. The open channels would vary in width from approximately 20 feet to 150 feet; depths of flow would vary from approximately 1.5 feet to 4.5 feet; and minimum freeboard would be one-half foot. The total estimated first cost for the west and south channels is $15.4 million, with estimated total annual costs of $1.6 million. The total estimated first cost for the Caliente Creek dam, reservoir, and the channels is $58.7 million, with total annual costs of $5.7 million. POSITIVE IMPACTS: The project would benefit the agricultural lands and economies of the project area. The reduction of flood event occurrence and duration would prevent crop losses and allow the cultivation of higher value crops in once floodprone areas. NEGATIVE IMPACTS: Construction of the dam, spillway, and spillway approach would destroy or affect approximately 170 acres of saltbush scrub habitat and 447 acres of agricultural land. The proposed project would result in habitat losses and equivalent declines in wildlife populations. Approximately 144 acres of alkali sink habitat, with a high potential for use by the San Joaquin kit fox, would be impacted; approximately 124 acres of wash habitat that could be used by the blunt-nosed leopard lizard would be lost to reservoir and channel construction; approximately 50 percent of the current population of Bakersfield cactus, a candidate species, would be destroyed; and 175 acres of habitat for the San Joaquin kangaroo rat would be lost. The project would adversely impact the Sand Ridge.

Preparation date: July 9, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED MARATHON INDUSTRIAL/COMMERCIAL BUSINESS CENTER, TRACT 5167, HAYWARD, CALIFORNIA (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1985). AN - 36398940; 1440 AB - PURPOSE: An industrial/commercial development of 134 acres in the city of Hayward, California and the enhancement of two nearby wetland parcels, totaling 90 acres, to mitigate wetland losses on the 134-acre site are proposed. The project sponsor and permit applicant is Marathon U.S. Realties, Inc. The applicant's purpose is to receive requested permits to subdivide the 134 acres into 65 lots, to build the necessary infrastructure, and to sell the parcels to industrial builders for profit. The proposed industrial /commercial business center site is located mostly in the city of Hayward, bordered on the north by the existing Bockman Canal, on the east by the Southern Pacific Railroad embankment, on the south by the Sulphur Creek levee, and on the west by lands of the East Bay Regional Park District and Oro Loma Sanitary District. Five alternatives are discussed in detail. Alternative 1 is the project as proposed by the applicant. To provide flood protection onsite, approximately 34,000 cubic yards of fill would be placed along the western site border to create a levee connecting to the Bockman Canal and Sulphur Creek levees. The site would be subdivided into 65 lots ranging in size from 1.1 to 5.4 acres. The development would provide sites for builders at $5.00 to $6.50 per square foot. The city of Hayward would provide sewer, water, police, and fire protection services for the site. The proposed mitigation parcels are included as part of the proposal. Ten-foot-wide channels would be dug to drain the interior of the parcel. A 30-foot wide ditch would route stormwater from the northeastern corner of the site to the south end and then to the outlet at the northwestern corner of parcel A. Three islands would be built and covered with sand and fine gravel. An inlet structure at the northeast corner of parcel A, opening into Sulphur Creek, would be controlled by a screwgate and flashboards. Parcel B would be maintained as an open-water area throughout the summer. One island of approximately 0.4 acre would be built in the ponded area. A 48-inch culvert with a slide flapgate would be located at the upper end of the ditch that connects parcels A and B. This culvert would remain open most of the time, but could be used to control drainage in either parcel without affecting the other. Alternative 2 would be the project as proposed by the applicant with alternative mitigation. No enhancement actions would be undertaken on parcels A and B; instead, approximately 90 acres of wetlands would be provided for mitigation, through purchase and dedication to a public agency of existing wetlands under private ownership or through active enhancement of nonwetland or low value wetland areas. Alternative 3 would develop east of the proposed loop roadway, with approximately 30 to 60 acres west of the western part of the loop road remaining as undeveloped wetland and approximately 104 or 74 acres, depending on the alternative, being developed as an industrial business park. Each of these alternatives, however, involves development on portions of the on-site wetlands. Alternatives that would not affect the on-site wetlands are Alternative 4, acquisition of the site by a public agency, and Alternative 5, no action. POSITIVE IMPACTS: Approval and ultimate development of the proposed project would change the 134-acre tract from undeveloped partially grazed land to a combined light industrial/commercial business center. Under Alternative 1, enhanced shorebird habitat would result. Wildlife habitats, including deep water, shallow water, islands, and vegetated slopes, would increase. Water circulation and dilution of summertime seepage from the adjacent landfill would increase. Old refuse presently exposed on the surface around the margins of the parcels would be removed or buried. NEGATIVE IMPACTS: Alternatives 1 and 2 would result in the loss of 90 acres of seasonal wetland habitat. Alternative 3 would eliminate approximately 60 acres of seasonal wetland habitat.

Preparation date: July 9, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED SWINOMISH MARINA, LA CONNER, SKAGIT COUNTY, WASHINGTON. AN - 36401102; 1453 AB - PURPOSE: Development of an 800-slip marina and associated facilities by the Swinomish Indian Tribal Community, located on a 132-acre site on the west shore of the Swinomish Channel immediately north of State Route 20 near La Conner, Skagit County, Washington, is proposed. The project's waterborne development includes 2,290 linear feet of rubblemound breakwater, 1,600 linear feet of channel revetment, 3,100 linear feet of riprap along the slopes of the marina basin, 114,640 square feet of floating docks for 450 slips with capacity for an additional 350 slips at a later date, a fuel dock, a four-lane boat lanuch, and a boat repair basin. A float plane facility is also being considered at this time. Onshore marina-related development includes a harbormaster office and space for Coast Guard offices, chandlery, retail shops, restaurants, motels, condominiums, and associated parking. The proposed plan also includes the dredging of approximately 942,400 cubic yards of intertidal and subtidal land to create the marina and boat repair basins. Disposal of the dredge material is planned for fill areas at various locations on the site. Approximately 30.8 acres of intertidal and subtidal land would be filled. POSITIVE IMPACTS: The proposed pleasure craft marina would serve two primary purposes: to meet the moorage needs of the recreational boating public, and to provide economic development opportunities for the Swinomish Indian Tribal Community. It is anticipated that construction of the proposed project would generate a minimum of 100 construction jobs. Full development is anticipated to create up to 230 permanent jobs for members of the Swinomish Indian Tribal Community. These potential job opportunities would serve to provide the economic stimulus that the tribal community desires. The site would be altered from a commercial bingo parlor and vacant uplands to a marina with upland support facilities. A maximum of 29,850 annual boat trips, with a maximum of 8,000 peak month trips, 640 peak day trips, and 96 peak hour trips are estimated. NEGATIVE IMPACTS: Dredging and filling would alter on-site elevations. The proposed action would result in the potential for accidental spills of oil or sewage into open water. The project would eliminate 7.1 acres of dune vegetation and 26.4 acres of upland meadows on the site. Dredge and fill operations would result in the combined net loss of 10.8 acres of wetland (saltmarsh) and 46.8 acres of intertidal mudflat at the project site. Approximately 2.7 acres of benthic habitat in the lagoon would be eliminated due to fill operations. There would be a reduction in the salmon rearing capacity of the project site, and bird populations could be reduced by an estimated one-third. Increases in noise and human activity in the site vicinity might affect harbor seals, river otters, birds, and wildlife. A float plane facility would create potential conflicts with boat traffic in the Swinomish Channel. An additional 40.9 acres of impervious surfaces at the project site would increase stormwater run-off.

With life spans typically less than 200 years, subdeltas, or bay-fill deposits, are scaled-down versions of major delta lobes, yet provide, through pulses of sediment, nearly all the subaerial land in an active delta. Using maps, charts, and aerial photographs, curves were constructed for rates of change in land area, sediment volume, and linear progradation in the four subdeltas that have formed on the modern Mississippi River Delta since the first accurate survey in 1838. Results indicate that each subdelta (1) lasted for approximately 115-175 years, (2) included periods of both growth and deterioration, (3) was initiated by a crevasse or break in the natural levee system, (4) showed linear advancement and volumetric growth during subaerial deterioration , and (5) displayed a new pulse of subaerial growth during the high-discharge decade of the 1970s. Contrary to popular accounts , demise of the Mississippi River Delta through deterioration of its subdeltas is not a result of the construction of artificial levees upstream or discharge of sediment off the continental shelf edge. Rather, it is attributable to a substantial decrease and fining of sediments being transported downstream to depositional sites within a delta that has developed, through natural processes, a complex and inefficient channel network for delivering these sediments.

AN - 36405396; 1444 AB - PURPOSE: Improvement of the existing deep-draft terminal channel at Port Sutton, Florida for commercial navigation is proposed. Port Sutton is located on the northeast side of Hillsborough Bay in Tampa Bay on the west coast of central Florida. The Port Sutton Terminal Channel is an east-west waterway connecting with the west side of the Port Sutton turning basin, enabling access to terminal facilities of the port. The preferred alternative provides for a channel 3,700 feet long, with a bottom width of 200 feet at a depth of 43 feet. The selected plan would involve the removal of approximately 280,000 cubic yards from 15 acres on the bottom of the terminal channel. Future maintenance material is estimated at 20,000 cubic yards annually. Disposal of initial construction material would be into an upland area near the port; maintenance materials would be placed on the nearest disposal island for the Tampa Harbor project in Hillsborough Bay. The excavating equipment would likely be a pipeline dredge, with disposal in a diked area of approximately 25 acres. The excavation quantities include 1 foot of overdepth allowance for dredging inaccuracies, with a 2-foot required overdepth in rock. The material to be removed is a varying mixture of rock, sand, silt, and clay, with an overall high percentage of fines making it unsuitable for landfill. The average side slope resulting from the excavation is estimated at 1 foot vertical to 3 feet horizontal. The Tampa Port Authority would be responsible for the construction of the disposal area dikes and land acquisition. The dikes would include discharge weirs to control turbidity, and would be approximately 14 feet high, with a crown width of 6 feet and 1 on 3 side slopes. Material for dike construction would come from within the proposed disposal area. The estimated cost to construct the preferred alternative is $2.7 million, based on an estimated time of 4.5 months to complete the work. The average annual benefits and costs are an estimated $997,000 and $273,000, respectively. The benefit-to-cost ratio would be 3.6 to 1. POSITIVE IMPACTS: Navigation improvements within Port Sutton would encourage development of cargo and handling facilities. The depth of the channel would accommodate the majority of the economically loaded bulk carrier vessels seeking entrance into Port Sutton at present and in the future. NEGATIVE IMPACTS: The proposed plan would have the potential of injuring manatees by boat collisions and propeller lacerations during project construction activities.

Preparation date: June 26, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CALIFORNIA-OREGON TRANSMISSION PROJECT AND THE LOS BANOS-GATES TRANSMISSION PROJECT, CALIFORNIA, OREGON, AND WASHINGTON (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF NOVEMBER 1986). AN - 36402683; 1417 AB - PURPOSE: Expansion and reinforcement of the Pacific Northwest-Pacific Southwest (PNW-PSW) Intertie by electrical transmission projects of public and privately owned utilities are proposed in California, Oregon, and Washington. The projects have multiple purposes and would essentially provide a third 500-kilovolt (kV) alternating current (AC) transmission path between southern Oregon and central California (California-Oregon Transmission Project (COTP)); complete a third 500-kV AC transmission path in the San Joaquin Valley of California (Los Banos-Gates Transmission Project); and reinforce the existing 500-kV AC transmission system facilities in Oregon and southern Washington (Pacific Northwest (PNW) Reinforcement Project). The Transmission Agency of Northern California, Western Area Power Administration (WAPA), and privately owned utilities and additional public entities propose to build an approximately 340-mile-long 500-kV AC transmission line from southern Oregon to the Tesla Substation in central California for the COTP. The project would include a new substation near either Malin, Pinehurst, or Keno, Oregon; approximately 140 miles of new 500-kV transmission line from southern Oregon to a new substation near Redding, California; approximately 170 miles of reconstructed 230-kV to 500-kV transmission line owned by WAPA from the new Redding area substation to the Sacramento River; approximately 20 miles of new 500-kV transmission line from the Sacramento River to the existing Tracy substation; a new series compensation station near Maxwell, California; expansion of the Tracy substation; and approximately six miles of new 500-kV transmission line between the Tracy substation and the existing Tesla substation. For the Los Banos-Gates Transmission Project, the Pacific Gas and Electric Company proposes to build an approximately 84-mile-long 500-kV transmission line in the foothills of western San Joaquin Valley between the existing Los Banos and Gates substations. The Los Banos-Gates Transmission Project includes approximately 84 miles of new 500-kV transmission line; realignment of the existing Los Banos-Midway No. 2 500-kV transmission line into Gates substation; modification of the Los Banos and Gates substations to accommodate new equipment and line connections; installation of shunt capacitors at various existing substations; possible installation of series capacitors at Gates and/or Midway substations; and restructuring portions of the Gates-Arco-Midway 230-kV transmission line. For the PNW Reinforcement Project, the Bonneville Power Administration, Pacific Power and Light Company, and Portland General Electric Company propose to build new and to modify existing transmission lines and supporting facilities in southern Washington and Oregon. Approximately eight miles of new 500-kV transmission line are proposed. Modifications may be made to 13 or more existing substations. One new substation may be constructed between the existing Marion and Alvey substations. This supplement describes new route options that would be 1,500 feet wide, and an additional potential site for the Southern Oregon Switching Station. Several routes and modifications are proposed in the vicinity of Grizzly Peak and in the preferred routes south of the Sacramento River and between the Tracy and Tesla substations. The new routing options in the northern section study area for the COTP include routes near Malin in Klamath County, Oregon; near Newell in Modoc County, California; near Black Mountain and Bear Mountain in Siskiyou County, California; and near Grizzly Peak and Round Mountain in Shasta County, California. In the southern section study area for the COTP, new options include routes on Veale Tract, Palm Tract, Orwood Tract, and Byron Tract in Contra Costa County, California; Victoria Island in San Tesla Substation in Alameda County and San Joaquin County, California. The third alternative site for the Southern Oregon Switching Station is located near Malin, Oregon. POSITIVE IMPACTS: The proposed actions would expand the bidirectional capability of the PNW-PSW Intertie transmission system and would help serve California's need for economical power, the PNW's desire to sell surplus power, and the need for maintaining and increasing the reliability of the existing transmission system. The COTP would add approximately 1,600 megawatts (MW) of additional transfer capability between the PNW and California. The projects would also add to and strengthen the existing high voltage transmission links between California and the PNW, provide for greater access to northwest power surpluses, facilitate more efficient use of regional power resources, provide greater resource diversity, and enhance transmission system reliability. NEGATIVE IMPACTS: For the COTP, potential adverse effects include excessive wind and water erosion. Wildlife effects include the possibility of collision of special-status and sensitive bird species or waterfowl with conductors and shield wires. Land use impacts include crossing prime timberland, prime farmland, and agricultural preserves. Visual effects would be reduced, but would remain significant following application of mitigation measures. Potential socioeconomic effects include inadequate temporary housing facilities for construction workers, reduced agricultural production, construction of new access roads, and location of transmission lines within areas close to residential communities. The Los Banos-Gates Project would result in only minimal impacts to earth resources, air and water quality, and public health and safety. The primary short-term impact includes disturbance of approximately 260 acres of land due to construction activities. Long-term operational impacts include a maximum loss of approximately 150 acres of land to access roads and tower foundations and a change in aesthetic quality due to the presence of towers in certain viewsheds. For the PNW Reinforcement Project, additional land would be required to accommodate some of the new equipment. New rights-of-way would have to be acquired for approximately eight miles of new transmission line.

Preparation date: June 26, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CONFINED DISPOSAL FACILITY FOR MAINTENANCE DREDGING OF THE FEDERAL NAVIGATION CHANNEL IN THE CLINTON RIVER, MACOMB COUNTY, MICHIGAN (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1976). AN - 36395786; 1446 AB - PURPOSE: Construction of a 30-acre confined disposal facility (CDF) on state property adjacent to the Selfridge Air National Guard Base (ANGB), located on the north side of the Clinton River approximately three miles upstream from the river mouth in Macomb County, Michigan, is proposed. This clay-lined facility would be used to contain the material to be dredged from the Clinton River Federal Navigation Channel, where shoaling has occurred. Total capacity of the 30-acre facility for 10 years is approximately 370,000 cubic yards. In the past, maintenance dredging activities were performed by both mechanical and dredge types. The currently proposed dredging operations would remove the shoaled sediment by mechanical dredge, place the material in a barge, and transport the sediment to an offloading area, where the material would be placed in trucks and hauled to the disposal facility. An offloading/transfer facility would be constructed on approximately 2.5 acres of property leased from the Selfridge ANGB. A steel sheet piling wall and a steel-supported concrete platform would be constructed along the river edge, enabling a dredge scow to be unloaded directly into trucks for transfer to the disposal facility. Upon completion of the filling, the clay-lined facility would be filled, then capped with clay, topsoiled, seeded, and revegetated, which would take approximately 10 years. The facility would then be turned over to the Michigan Department of Natural Resources for possible recreational use. A haul road would be constructed to form a loop to the platform for truck entry and exit. The road would remain intact when the property is turned back to the ANGB. The proposed action may also involve construction of one or more temporary structures. The temporary placement of clean fill or construction materials on upland or aquatic areas outside of wetlands may also be necessary. Estimated costs would be $2.2 million. POSITIVE IMPACTS: Construction of a clay-lined disposal facility would effectively seal the polluted dredged material from the environment. Because of the clay liner, groundwater would be effectively sealed off and prevented from contact with dredged material. The dredged channel would allow the continued safe movement of recreational craft, and local benefits would be derived from providing for the various marinas to remain functional. NEGATIVE IMPACTS: Thirty acres of shrub/scrub land would be changed as an upland habitat. The upland habitat that would replace the existing area might be less attractive to the existing flora and fauna. Construction activities may be aesthetically displeasing to residents. Trucking activities would cause some disturbance in the area from traffic, noise, and dust.

AN - 36402067; 1445 AB - PURPOSE: Alternatives to the operation and regulation of Lake Red Rock, in Marion County, Iowa, are being considered. The current operation plan requires raising the lake at intervals to compensate for sedimentation and to maintain the 50,000 acre-feet of water originally approved for the reservoir. This is the No Action alternative. Other alternatives would provide for raising the lake to predetermined levels at predetermined intervals. Alternatives that have been considered involve revised release rates and include: maintaining present operations; dry reservoir; a one-step raise from 728 to 742 feet National Geodetic Vertical Datum (NGVD); a two-step raise from 728 to 736 to 742 feet NGVD; a three-step raise from 728 to 732 to 736 to 742 feet NGVD; and dredging of accumulated sediments. The recommended plan involves an immediate raise to elevation 736 feet NGVD and a final raise to 742 feet NGVD. The intermediate step to elevation 736 feet NGVD could be physically accomplished in 1988 with no structural modifications. The conservation pool would be raised two feet in the fall for the benefit of migrating waterfowl in coordination with the Iowa Department of Natural Resources. Since filing of the final environmental impact statement in August 1976, no substantial changes in planned activities have taken place. Periodic structure repair and landscaping and maintenance of launching ramps, swimming beaches, signs, and trails have been required on a more frequent basis than originally anticipated due to damage from near-record precipitation and flood events in the Des Moines River Basin. First costs are estimated at $1.5 million, with a benefit-to-cost ratio of 1.8. POSITIVE IMPACTS: The recreation experience at the lake would be enhanced by improving aesthetics, boating, fishing, and wildlife habit, and part of the recreational needs of south-central Iowa would be fulfilled. Residential property values could increase slightly. The increased potential for recreation visitors to the lake could attract new businesses to the area and create new employment opportunities. NEGATIVE IMPACTS: Construction machinery would generate a temporary increase in noise during scheduled relocation of facilities, creating a minor, short-term disturbance to recreationists at the lake. Recreation at various facilities would be temporarily disrupted during the construction phase. The values of farm properties could be adversely impacted. An increased risk of flooding, resulting from any raise in pool elevation, is perceived by area farmers. LEGAL MANDATES: Water Resources Development Act of 1976 (42 U.S.C. 1962d et seq.).

Preparation date: June 23, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - THIRD PORT PROJECT (PERMIT APPLICATION NUMBER 84B-4488), LIMETREE BAY, SAINT CROIX, UNITED STATES VIRGIN ISLANDS. AN - 36398802; 1452 AB - PURPOSE: The Virgin Island Port Authority has applied for a Department of the Army permit for dredging material from Limetree Bay, located on the south shore of Saint Croix, U.S. Virgin Islands, and for discharging material and placing structures into wetland areas. The purpose of this work is to expand the Third Port project at Limetree Bay to create a navigable deepwater port and related facilities. Alternatives that were considered included alternate locations and site plans for the proposed development. No alternative location was found in the St. Croix area that would meet the need for future port development. Numerous maritime organizations require port facilities capable of serving large deepdraft ships. An objective of this port development is to serve as a transshipping center for waterborne commerce in the region. The proposal includes improvement of the present channels and waterways to permit navigation of large ships and the construction of a 2,300-foot general cargo wharf, extending from the existing ro-ro ramp at the container port to the jetty bordering the Martin Marietta Channel. The project would be developed in three stages. Approximately 4.1 million cubic yards of material would be dredged. In Stage I, all of the dredging required for development of waterways would be completed, including a turning basin to a depth of 35 feet below mean low water (MLW). One of the berths would be constructed at the marginal wharf, and all of the uplands adjacent to the new port would be developed using dredged material. In Stage II, the second new berth would be constructed at the marginal wharf, realizing the full potential of the site. Stage III planning provides for deepening the waterways and basin in the long-term future to 39 feet below MLW and widening the access channel. Total operating and maintenance costs are estimated at $33.3 million. Estimated annual revenues from marine use fees of the harbor and terminal are estimated at $2.9 million, and from property leasing and rental at $1.03 million. POSITIVE IMPACTS: Economic benefits would be realized in reduced transportation costs and expectations of increases in waterborne commerce for Saint Croix and also for the Caribbean region. The plan would improve the channels and waterways to permit the navigation of large ships. Expansion of the present container port to a deepwater port for the handling of bulk cargoes, containers, break-bulk cargo, and construction materials and equipment would make a positive contribution to the social and economic well-being of the citizens of the U.S. Virgin Islands. It would also allow for direct shipment of goods to the port, eliminating the loading and off-loading of cargo at other ports. This would result in a significant reduction in the cost of living. Disposal of dredged material in the uplands north of the Limetree Bay shoreline would have no adverse impacts on the flora and fauna in this area. NEGATIVE IMPACTS: Dredging and filling at the proposed site would eliminate approximately 152 acres of seagrass meadows and 16 acres of mangrove wetlands. Water quality would be temporarily degraded by increased turbidity as a result of suspended sedimentation.

Preparation date: June 22, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - EL PASO LOCAL PROTECTION PROJECT, SOUTHEAST AREA, EL PASO, TEXAS. AN - 36395737; 1410 AB - PURPOSE: Flood protection for residents in the southeast area of El Paso, Texas is proposed. The recommended plan would use a combination of existing and new flood detention basins and channels to collect, detain, regulate, and discharge floodflows into a segment of the existing agricultural drainage system, that is, the Mesa Drain. All detention basins would have gated outlets, and detained floodwaters would be released at such times and rates that would be safely accommodated in the receiving Mesa Drain. This water would in turn flow into Feather Lake, the Mesa Drain Interceptor, and finally into the Playa Lateral Detention Basin. Infrequent excess storage from this basin would be pumped into the Rio Grande above the Riverside Diversion Heading. Maximum regulated discharge through the gated outlet conduits of the basin would be 70 cubic feet per second. Each basin would evacuate detained floodwater in one to three days. Sequential evacuation of the basins, based on downstream conditions at Mesa Drain, would result in a maximum retention period of 11 days for the system. Earth required for basin embankments would be obtained from the basin area. All channels would be concrete-lined to protect the lower sides and bottom from scouring. Any needed rock protection would be obtained from commercial sources in the El Paso area. All structures would be constructed on alluvial deposits of sands, silty sands, sandy clays, and clays derived from the Franklin Mountains and the Rio Grande. Borrow materials would also consist of these soil types. The silty sands would provide an adequate material for soil cement. Basins would be fenced for public safety and to discourage vandalism. The Chevron Dam and Basin is the uppermost element of a system of two detention basins and a connecting channel that would collectively protect the western portion of the Southeast Area. The two remaining features are Phelps Dodge Channel and Phelps Dodge Dam and Basin, both existing flood control features. Additional new features would be the Lomaland Diversion Channel, Dam, and Basin; the Bluff Channel; and the Americas Basin. Recreational, fish, and wildlife facilities could be developed in conjunction with flood control features. The estimated cost of the total project is $67.5 million, with total annual costs of $6.4 million and a benefit-cost ratio of 1. POSITIVE IMPACTS: This comprehensive flood control system would provide 100-year protection to the community. Economic losses from large-magnitude storms would be prevented or reduced. The plan would protect the function and integrity of the drainage system by retaining sediment and debris as well as preventing sloughing of drain sideslopes. Sediment accumulation in Feather Lake would be reduced significantly. The project would result in an enhanced protection to community health and safety from the adverse effects of major flooding. NEGATIVE IMPACTS: Approximately 193 acres of land reserved or planned for industrial, commercial, or residential use would be withdrawn for flood control purposes. There would be a small loss of terrestrial habitat and a small wetland. Three city parks would be affected, one significantly. There would be minor and local degradation of air quality during construction.

AN - 36406115; 1400 AB - PURPOSE: A relief route for U.S. Route 13, Route 7 to U.S. Route 113, in central Delaware is proposed. The study area includes the areas approximately two to three miles to the east and west of present U.S. Route 13. The limits of the proposed project extend to Tybouts Corner on the north, where new Delaware Route 7 improvements are to terminate, to the Frederica and Felton areas south of Dover (including U.S. Route 113 and U.S. Route 13). The proposed project consists of a 46-mile fully controlled access highway facility in central Delaware to provide sufficient traffic capacity to address problems existing in this corridor and traffic volumes anticipated in the next 20 years. The project has been divided into the Odessa, Smyrna, and Dover segments. The Odessa segment extends from the northern terminus of the project area at Tybouts Corner, where a new interchange between U.S. Route 13 and Route 7 is being designed, to Pine Tree Corner Road. This area is primarily rural /agricultural. The Upgrade Alternative in general calls for the reconstruction of the existing highway from Tybouts Corner to Pine Tree Corner into a four-lane divided, fully controlled-access facility, with the development of service roads where necessary for local traffic. Included in this concept is a new crossing of the Chesapeake and Delaware Canal west of the existing St. Georges Bridge and a westerly bypass of Odessa. The Relief Route would be moved off the existing rights-of-way to the west, beginning at the intersection of existing U.S. Route 13 and Route 7 to just south of the Chesapeake and Delaware Canal. The new canal bridge would be located west of the existing St. Georges Bridge in such a way as to avoid historic resources and a public school and playground. The Smyrna segment begins at the termination of the Odessa segment at Pine Tree Corner Road and continues south to the Leipsic River. The preferred alternative for this segment, near East/near West, parallels the existing highway within one-quarter of a mile except at Smyrna, where the Relief Route diverges farther to the east. The existing highway would remain in service in its current configuration. The location and design of the route have been refined in the vicinity of Union Church Road, Black Diamond Road, Duck Creek Road, and U.S. Route 13 north of Smyrna. The Dover segment begins at the termination of the Smyrna segment at the Leipsic River and continues to just south of the Dover Air Force Base on U.S. Route 113 and to Road 30 on U.S. Route 13. The segment has two major southern connections, one to U.S. Route 13 and the other to U.S. Route 113. The selected alternative, near East, parallels existing U.S. Route 13, approximately 3,000 feet to the east. South of Dover it rejoins both U.S. 113 and U.S. Route 13. It continues south on upgraded sections of each road to the project termini. Again, the exact location and design of this segment and its interchanges have been refined in an effort to reduce impacts on critical resources. The total project cost is estimated to be $474 million. POSITIVE IMPACTS: The project would achieve traffic service at the level of service B in rural sections and service C in the Dover sections on a year-round average traffic basis for the design year of 2004. Construction employment would amount to 5,255 person-years; the macroeconomic employment gains would amount to 1,480 jobs for the entire corridor. NEGATIVE IMPACTS: The preferred alternative would result in the relocation of 97 houses, 15 mobile homes, and 30 apartment units, as well as 72 businesses, 2 churches, and 2 government offices. Net direct and indirect jobs lost to rights-of-way acquisition would number 134. It is estimated that 110 farms would be affected, with 610 acres of prime soil and 271 acres of soils of statewide importance being taken. The annual agricultural economic loss is estimated at $674,900. Approximately 450 acres of high-quality habitat would also be taken. In addition, 207 acres of wetlands would be eliminated and 118 acres would be directly impacted. In 27 locations, 101 noise receptors would be adversely affected. Although no historic structures would be directly affected, 22 structures would suffer indirect impacts. It is estimated that 13 prehistoric and 6 historic archaeological sites would suffer some impact.

AN - 36405316; 1411 AB - PURPOSE: Implementation of a land and water resources management plan is proposed for the Grays Harbor estuary on the southern coast of Washington state. The 91-square-mile estuary is 13 miles across at its widest point and narrows to less than 100 yards in its upper reach nearly 32 miles from the mouth. The three corners of the estuary are defined by the mouth of the Chehalis River flowing into the eastern portion of the harbor; the North Bay, which receives the waters of the Humptulips River; and the South Bay, into which the Elk and Johns rivers flow. The focus of the management plan would be to define areas in which future activities and growth would be acceptable and to minimize adverse impacts. Developed by an intergovernmental agency task force, the multiple-use plan would divide the estuary into 8 planning areas and 43 management units for zoning purposes. Management unit designations would provide for land uses ranging from maintenance of natural conditions through development of agricultural and urban uses. Approximately 82.5 miles of waterfront land would be managed for conservation purposes, while the remaining 39.8 miles of shoreline would be managed for development. Plan policies would regulate placement of structures in the estuary, modification in shorelines and development of bankline erosion control features and landfills, channel excavation and maintenance, log rafting, and mitigation of damage done to the estuary due to construction activities. Plan concepts would specifically address the urban waterfront, shallow intertidal and subtidal fish passage areas, the Bowerman Industrial Area, airport development, and public access and waterfront rehabilitation. POSITIVE IMPACTS: Beneficial impacts include greater protection and enhancement of large areas of the shoreline and estuarine environment, protection of the regional economic base and the potential for future economic development, improved transportation systems, and others associated with orderly land development. NEGATIVE IMPACTS: Development allowed by the plan could result in the filling of up to 700 acres of aquatic habitat, and would result in modification of the shoreline due to construction of urban structures. Dredged material disposal and filling would alter the topographical features of the estuary, and the tidal prism would be reduced one percent. Portions of salt marsh and eelgrass beds and other vegetation would be removed. The plan would limit development options along the shoreline.

Preparation date: June 3, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MANSELL ROAD EXTENSION AND INTERCHANGE WITH GA 400, FULTON COUNTY, GEORGIA: PROJECT FR-056-1(45). AN - 36405034; 1401 AB - PURPOSE: Extension of existing Mansell Road from its intersection with Old Roswell Road in Alpharetta, Fulton County, Georgia is proposed. The road would run easterly on new location to a point on Old Alabama Road in the vicinity of its intersection with Turner Road, located in Roswell, Georgia. A full diamond interchange would be added, connecting the Mansell Road extension with GA 400/U.S. 19 midway between the Holcomb Bridge Road and the Haynes Bridge Road interchanges. The extension would bridge over GA 400/U.S. 19 at the proposed interchange. Total length of the proposed project is approximately 3.0 miles. The Mansell Road extension would be constructed on a minimum of 150 feet of rights-of-way width and would consist of two 12-foot wide lanes in each direction of travel, separated by a 20-foot wide raised median. Construction cost of the locally funded extension is estimated at $16.2 million, and the cost of the federal- and state-funded interchange is estimated at $4.9 million. POSITIVE IMPACTS: The proposed extension of Mansell Road and the interchange with GA 400 would provide needed access to an area experiencing new development. By providing new access to the area, the heaviest peak hour congestion on Holcomb Bridge Road and its interchange with GA 400 could be minimized. There should be a decrease in accidents on Holcomb Bridge Road as a result of project implementation and an improvement in fuel efficiency for motorists using the new facility to travel to and from points within the project study area. Air quality would improve. NEGATIVE IMPACTS: Two residences would experience noise impacts; one residence would be displaced. Approximately 1.7 acre of wetlands would be impacted by the proposed project. All phases of construction operations would temporarily contribute to air pollution.

Preparation date: June 3, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED LAND ACQUISITION FOR YAKIMA FIRING CENTER, KITTITAS, YAKIMA, GRANT, AND BENTON COUNTIES, WASHINGTON. AN - 36402106; 1375 AB - PURPOSE: Expansion of the Yakima Firing Center (YFC) by acquiring approximately 63,000 acres of land adjacent to the present YFC boundaries and two sites along the east shore of the Columbia River is proposed. The YFC military training center is a subinstallation of Fort Lewis, located in Yakima, Kittitas, Grant, and Benton counties, Washington, approximately seven miles north of the city of Yakima. The YFC is used for military field training, primarily by the 9th Infantry Division (motorized (MTZ)), U.S. Army Reserve, and National Guard to improve their military readiness. The YFC also serves the Air Force, Navy, Marines, Coast Guard, some foreign military forces, and others in carrying out various military training activities. The lands to be acquired include a northern expansion area, an eastern expansion area, and two crossing sites on the east bank of the Columbia River. Military use of the proposed expansion lands would include maneuvers by both wheeled and tracked vehicles, foot traffic (maneuvers), overland flights by helicopters and high-performance aircraft, bivouac and staging activities, weapons firing, and river crossing on a year-round basis. No permanent population occupies the present expansion areas, although a number of single-family residences and low-density rural settlements occur adjacent to the areas, the largest of which is the Desert Aire Retirement Community located on the eastern bank of the Columbia River. POSITIVE IMPACTS: Expansion of the YFC would increase its area by 63,000 acres, adding 62,000 acres of rangeland to the north of the existing YFC, a right-of-way along the eastern boundary, and two river crossing sites on the east bank of the Columbia River, opposite the existing YFC. In the interest of national defense, the Army would acquire this land to accommodate the growing operational demands of the YFC and to properly support its combat readiness mission. Expansion of the YFC would also allow the 9th Infantry Division (MTZ), other 1 Corps components, reserve components, and the National Guard additional flexibility in conducting large-scale military training activities and river crossing exercises. The latter are an integral part of land warfare, and the exercises must be practiced regularly. Acquisition of the eastern expansion area would provide the installation with river access and would facilitate security, fire control, and movement/access along the eastern boundary of the YFC. Acquisition of the Milwaukee Road corridor would provide a relatively level north-south access route on the east border of the YFC and eliminate occasional accidental trespassing on private lands. It would also eliminate the need to acquire "as required" training permits, which limit the Army's flexibility in planning and conducting realistic training exercises. NEGATIVE IMPACTS: Adverse environmental effects would occur on cultural resources, recreational opportunities, wildlife habitat, and quality of life for area residents. Mitigation measures for these impacts are proposed. The Army would control future oil, gas, and mineral exploration in the expansion areas. Increased erosion would result from military maneuvers and vehicular activity. River crossing activities would impact fish migration and rearing and could interfere with future commercial navigation on the mid-Columbia River. Increased troop, vehicular, and air support activities would disturb resident and migratory birds and animals. Weapons firing and aircraft operations would increase noise levels.

AN - 36398594; 1399 AB - PURPOSE: Widening State Route (SR) 118 (a conventional highway) to four lanes from SR 126 (the Santa Paula Freeway) to SR 232 (Vineyard Avenue) in Ventura County, California is proposed. The Santa Clara River bridge would be replaced and the State Route 118/126 bridge would be widened. Two build alternatives are being considered. Both alignments would follow existing Route 118 (Wells Road and Los Angeles Avenue), and both propose a four-lane conventional highway, including replacement of the Santa Clara River bridge. The jogs in the existing alignment at Violeta Street and Los Angeles Avenue and Violeta Street and Wells Road would be eliminated. Modification of the Route 118/126 interchange would consist of widening the existing overcrossing structure and modifying two ramps. The highway would be at grade, except in the vicinity of the Santa Clara River bridge. Approaches to the bridge would be on fill, as they are now. A No Project Alternative, which would leave Route 118 as it is today, is also under consideration. If the No Project Alternative is selected, bridge replacement alternatives would have to be developed. Due to the deteriorating condition of the Santa Clara River bridge, it would have to be replaced. Alternative B has an estimated total cost of $17.3 million and Alternative B-C, $18.7 million. POSITIVE IMPACTS: Energy consumption would decrease slightly. Realigning and widening Route 118 would relieve congestion and lead to higher speeds and shorter travel time, which would reduce the pollutant levels from traffic. NEGATIVE IMPACTS: Traffic noise levels would exceed federal noise standards. Alternative B would affect 14 businesses with 28 to 44 employees; Alternative B-C would affect 23 businesses with 41 to 91 employees. Alternative B would bisect a residential section of Saticoy and remove five housing units; an estimated 32 persons would be displaced. Under this alternative, most businesses on the north side of Los Angeles Avenue would be removed. Alternative B-C would remove five homes on Wells Road, displacing an estimated 18 persons. Alternative B would directly take 6.5 acres of prime farmland east of Wells Road and south of Rosal Lane. The long-term effect of reconstructing the Santa Clara River bridge would be a permanent loss of 0.2 acre of wetland vegetation. Construction activities would alter slope angles, and clearing of wetland and upland vegetation would increase erosion and the amounts of sediments going downstream. This would adversely affect aquatic organisms, anadromous species, and wetland vegetation.

AN - 36387203; 1402 AB - PURPOSE: Construction of a multilane divided highway, designated as FAP 426, from the intersection of U.S. Route 20 (Lake Street) and Lovell Road east of Elgin, easterly to the intersection of Illinois Route 19 (Irving Park Road) and U.S. Route 12/45 (Mannheim Road), in Cook and Du Page counties, Illinois, is proposed. The highway is 21.3 miles long. Alternatives considered were no action with normal use of mass transit; no action (transit intensive); upgrading existing roads in the area; and the build alternative, which involved three different traffic design concepts: (1) hightype arterial, (2) freeway design for the entire length of the project, and (3) the combination of a freeway design coupled with improvements to existing roads. Alternate B (Modified) with Options A and C, the build alternate selected, represents a combined freeway and arterial road design. The western terminus is at the intersection of U.S. Route 20 and Lovell Road in Elgin. The highway alignment follows U.S. Route 20 southeastward. At East Bartlett Road (North Avenue), FAP 426 swings south on new alignment through the southern portion of Hanover Park. East of Hanover Park, the alignment continues in a northeasterly direction. The proposed alignment extends easterly through Schaumburg and Roselle. At Rohlwing Road, the new alignment segment of the highway ends as FAP 426 and joins Thorndale Avenue. Itasca and Elk Grove border this segment of the FAP 426 alignment. Continuing east, the highway alignment follows Thorndale Avenue to York Road, passing through Wood Dale and into Bensenville. At this point, the highway turns southeasterly on a new alignment to intersect with Illinois Route 19. The FAP 426 alignment follows Illinois Route 19 to the eastern terminus at U.S. Route 12/45 in Schiller Park. Chicago-O'Hare International Airport borders this segment of the highway to the north. Option A is being considered from York Road to U.S. Route 12/45. As a distinctly separate alignment, the road would be shifted to a location north of alternate B (Modified) and approximately parallel to the Chicago & North Western Railway tracks between York Road and Illinois Route 19. This option includes a full interchange at U.S. Route 12/45 and Illinois Route 19. Option C applies to a segment of the highway in the vicinity of Gary Avenue, Illinois Route 19, and Rodenburg Road. This option has the same horizontal alignment as Alternate B (Modified), but has a different set of interchanges. The alternate and options may be combined to provide four separate build design alternates. POSITIVE IMPACTS: The proposed highway improvement would provide needed traffic capacity in the corridor between Elgin and Chicago-O'Hare International Airport, relieving local arterial traffic congestion. Long-term employment would be generated by construction of FAP 426. Property values would increase due to increasing population and economic growth, and improved accessibility would stimulate more efficient use of existing business, commercial, industrial, and manufacturing land uses. NEGATIVE IMPACTS: The project would require approximately 47 single-family home and 8 business, commercial, and industrial relocations. Six streams would be crossed by the proposed alignment, resulting in erosion of soil and subsoil into the streams. The loss of wetland acreage ranges from 43 to 50 acres, depending on the alternate selected. It is predicted that 36 residential receptors would experience traffic noise equal to or greater than the federal noise abatement criteria for residences. Four structures would experience significant increases in traffic noise. Spillage of oils, grease, and fuel during construction could adversely affect surface water quality.

Preparation date: May 21, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD CONTROL STUDY, FORT WAYNE, INDIANA AND VICINITY. AN - 36401180; 1408 AB - PURPOSE: A flood control plan for Fort Wayne and vicinity, in Allen County, Indiana is proposed. The selected plan provides for upgrading approximately 35,000 feet of levee, floodwall, and steel sheet pile crib along the Maumee, St. Marys, and St. Josephs rivers and Spy Run Creek with new levees and floodwalls, to be constructed only where necessary to tie the system into high ground. The structures would be constructed to the 200-year flood event protection level. The levees would be constructed of local material, with seepage protection on the slopes of the levees. A slurry trench would be constructed under all levee and floodwall lengths to prevent or reduce seepage. The top width would be widened to 10 feet, trees would be removed, and the river side slope would be improved to a minimum of 2 horizontal to 1 vertical. Any slopes steeper than 2.5 to 1 would require slope protection. Construction of the selected plan would raise the 100-year water surface elevation by 0.1 foot at the confluence of the three rivers. A 15,000 gallon per minute pumping station and approximately 6,000 linear feet of storm sewer would need to be installed to allow for interior drainage. Construction would require removal of existing dike and riverbank vegetation, including some large trees. The dikes would be planted with shrubs and grasses following project completion. The estimated first cost of the selected plan is $15 million. Estimated average annual benefits resulting from the plan would be $4.2 million, with an average estimated annual cost of $1.5 million. The resulting benefit/cost ratio would be 2.8. POSITIVE IMPACTS: A flood control project at Fort Wayne would have a beneficial impact on community cohesion by eliminating the flood threat that jeopardizes public health and safety and results in excessive property damages. Some property values may be increased but would not appreciably affect tax revenues. Employment opportunities would be generated during construction. NEGATIVE IMPACTS: Because vegetation would be removed from the banks for levee work, fish habitat would be adversely affected, since tree roots, fallen trees, and fallen branches and leaves form excellent fish foraging and escape cover areas. Also, since shade regulates temperatures of nearshore areas, the removal of vegetation would adversely affect temperatures of fish habitat. Riparian habitat would also be lost, as would associated wildlife use, due to levee construction. Major impacts to cultural resources would occur, particularly in downstream sections of the Maumee River. There would be temporary inconveniences due to road closures and other construction-related impacts during work periods. The increased dike height may be aesthetically displeasing to some community members. Construction noise would be especially disturbing to wildlife, and construction activity would increase travel by trucks in the area.

AN - 36401177; 1360 AB - PURPOSE: Channel improvements along the Alabama and Coosa rivers in Alabama and Georgia are proposed. Three separate segments would undergo improvements to open a 300-mile navigation channel from the mouth of the Alabama River upstream to Montgomery, Alabama: (1) the Alabama River from its mouth to the vicinity of Montgomery, Alabama; (2) the Alabama and Coosa rivers between Montgomery and Gadsen, Alabama; and (3) the Coosa River between Gadsen, Alabama and Rome, Georgia. Specific activities would include maintenance dredging of approximately 1 million cubic yards annually, predominant use of within-bank disposal areas, maintenance of training dikes on the river below Claiborne lock and dam, maintenance of hydropower facilities, maintenance of lock facilities, and maintenance of project lands, including a number of recreation facilities. Since initial dredging of the project in 1968 and 1969, annual maintenance dredging quantities have increased significantly in the Claiborne lock and dam area. This revised draft supplement to the final environmental impact statement of January 1976 reevaluates operation and maintenance activities in the Alabama River segment. Channel stabilization structures and site-specific disposal areas are proposed. The measures would include construction or modification of training dikes at 12 locations below Claiborne lock and dam, lowering the dredge reference profile based on reducing the channel design flow from 8,450 to 7,500 cubic feet per second, and expanding the dredging reaches. The number of within-bank disposal areas would be expanded. These areas would consist of unforested lands along the riverbank below the ordinary high water line and extending riverward. The number of above-bank disposal areas would also be increased. In order to mitigate for the significant wildlife resource losses that would occur due to construction and utilization of the above-bank disposal sites, intensive wildlife management on 645 acres of bottomland hardwood habitat on Bob Woodruff Lake lands is proposed. Annual benefits range from $13 million to $30 million. Costs are estimated at $8.1 million, with a benefit-to-cost ratio ranging from 1.6 to 3.7. POSITIVE IMPACTS: Continued maintenance of the system would permit economic development based on river transportation. Small-boat channel maintenance would improve access for waterborne recreational craft and for commercial fishermen along the Alabama River. NEGATIVE IMPACTS: Use of above-bank disposal sites would result in the loss of 183 acres of bottomland habitat, with potential long-term losses of up to 3,300 acres for the remaining 40 years of the project life. Approximately 28 acres of wetlands would also be lost. Streambed degradation below Claiborne lock and dam would affect the stability of the lock and dam. Sedimentation at the mouths of Limestone, Bailey, and Walters creeks would change the flow regimes, water quality, and fisheries of these creeks significantly.

Preparation date: May 12, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MINNESOTA TRUNK HIGHWAY 33 FROM JUNCTION OF INTERSTATE 35 TO JUNCTION OF U.S. TRUNK HIGHWAY 53, CARLTON AND SAINT LOUIS COUNTIES, MINNESOTA. (DRAFT SUPPLEMENT TO tHE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1985). AN - 36395253; 1348 AB - PURPOSE: The improvement of 19.7 miles of Trunk Highway (TH) 33 from the junction with Interstate Highway 35 (I-35) to the junction with TH 53 in Carlton and Saint Louis counties, Minnesota is proposed. In October 1985, a final EIS (FEIS) was approved for this corridor. This FEIS identified a preferred alternative for the northern rural section and a temporary no-build alternative for the southern urban section. This was done to allow more time to study the urban section. This supplement complies with the statement of the FEIS that a supplement would be prepared for the urban section. Including the No-Build alternative, four major alternatives were considered: West Cloquet Bypass: a bypass west of Cloquet; East Cloquet Bypass: a bypass east of Cloquet; and a Through Town Corridor: a route along existing TH 33. A typical cross-section of the urban design would consist of two 12-foot lanes, two 14-foot lanes, a 12-foot continuous left-turn lane, and sidewalks. Construction of the preferred alternative would result in a four-lane expressway. Interchanges with TH 53, TH 2, and I-35 are proposed. A one-mile section of TH 2 would be reconstructed to four lanes through the interchange with TH 33. The preferred alternative was analyzed by placing approximate alignments within corridors. The corridors were approximately 500 feet wide, except where potential constraints were found. In these areas, the corridor was expanded to a maximum width of 2,000 feet. POSITIVE IMPACTS: The project would provide four-lane continuity between the Twin Cities metropolitan area and the Iron Range cities, and it would improve accessibility to tourism areas in northern Minnesota. Highway accidents would decrease, primarily along the portion of TH 33 between I-35 and TH 2, and traffic flow through Cloquet would improve. The project also would stimulate business expansion and long-term economic growth in the area. Deficient bridge structures would be replaced or improved. NEGATIVE IMPACTS: The project would displace up to 23 residences and two small businesses. Approximately 25 to 54 acres of wetlands would be impacted. A portion of the abandoned Scanlon landfill would be relocated by the East Cloquet Bypass, and the Fond Du Lac Indian Reservation would be impacted by the West Cloquet Bypass. One historic site on the Through Town or East Cloquet Bypass alternative would be adversely affected and two parks, one significant and one undeveloped, would be adversely affected by the West Cloquet Bypass.

AN - 36400507; 1344 AB - PURPOSE: Additions to existing Route I-20 in Fulton/DeKalb counties, Georgia are proposed. The preferred alternative would include lane additions with safety recovery areas, a median barrier, and retaining walls, extending for 8.7 miles from Hill Street in Atlanta, Fulton County, to Columbia Drive in DeKalb County, Georgia. The proposed project would add two 12-foot concrete travel lanes and a safety recovery area or paved shoulder in each direction, plus a median barrier for the entire length of the project. The construction would be done primarily within the existing rights-of-way where possible, with the use of retaining walls where required. Acquisition of additional rights-of-way would be mainly in the interchange areas. All existing overpass and interchange bridges would be replaced. Rights-of-way requirements would vary from 110 feet to 200 feet. The estimated cost for the build alternative would be $80 million. POSITIVE IMPACTS: Air quality would be in compliance with state and federal Ambient Air Quality Standards; the project is part of an overall plan to improve air quality in the region. Traffic would be reduced on several local streets and would be greatly reduced on streets that are closed at one end. The project would help to reduce accidents on I-20. Improved vehicle efficency for commuters and for some local users would result as well. NEGATIVE IMPACTS: A small, imperceptible two decibel increase would occur over existing noise levels; a total of 94 sites would be above noise abatement criteria. The preferred alternative would use land from a historic district included in the National Register of Historic Places and from one district eligible for inclusion in the National Register. Approximately 18 residences and 5 businesses would be displaced.

AN - 36380727; 1363 AB - PURPOSE: The Port Everglades Port Authority has applied for a permit from the U.S. Army Corps of Engineers to place fill in U.S. waters and their contiguous wetlands. The Port Authority's purpose is to expand port facilities in Port Everglades in Broward County, Florida to accommodate an expected increase in the containerized cargo business, a portion of which would be carried out by the new Non-Panamax container ships. The Port Authority proposes to construct a containerized cargo-handling facility that would consist of an 18-acre turning notch off the Atlantic Intracoastal Waterway that would be located in the southeast corner of an existing 70-acre stand of mangroves, building an additional 800 feet of bulkheading on the same alignment as a 2,000-foot bulkhead now under construction, and dredging an additional 800 feet of the intracoastal waterway to a depth of 44 feet mean low water (mlw). As mitigation for the proposed action, the Port Authority proposes to construct 23 acres of new wetlands and to plant 160,000 mangroves, place 7,300 feet of limerock riprap on the east bank of the intracoastal waterway, create a 3-1/2 acre manatee refuge, create an endangered species/nature education facility, and grant a conservation easement to the state of Florida on approximately 50 acres of mangroves. POSITIVE IMPACTS: The Port Authority is proposing to expand its facility so that it would be able to conduct safer and more efficient waterborne commerce and to handle the projected cargo volumes. NEGATIVE IMPACTS: Since part of the port expansion has been permitted and is either built or under construction, there would be environmental consequences even if all pending permits were denied. Some use would be made of the existing facilities, which would result in additional traffic in the intracoastal waterway and increased turbidity. Of the endangered species that can be found in the vicinity of the proposed project, only the manatee may be impacted, since it would be subjected to slightly increased risk during construction. The degree of wetland/mangrove loss would be mitigated, although there would be a time lag of several years between the loss of mature mangroves and the maturation of planted mitigative mangroves. Some fauna would be unable to relocate and/or compete and would be lost.

AN - 36401949; 1364 AB - PURPOSE: Implementation of a flood control project is proposed for the city of Great Bend, Kansas. Great Bend lies on a flat plain between the Arkansas River on the south and Walnut and Little Walnut creeks on the north and west. The preferred alternative would divert the Walnut and Little Walnut creeks to the Arkansas River before they reach Great Bend by means of a seven-mile leveed diversion channel. Another leveed channel would divert Little Walnut Creek into the main diversion channel. The Arkansas River would be channelized with levees on either side, from the intersection with the main diversion channel to near its confluence with Little Walnut Creek. A ring levee would encompass the Great Bend Municipal Airport and Industrial Park. Appurtenant works would include an interior drainage system, structures to permit passage of water diverted from the river and Little Walnut Creek to Cheyenne Bottoms, construction of bridges and approaches for highways and railroads, and minor relocations of county roads. The average annual project cost is estimated at $3.9 million, and the benefit-to-cost ratio is 3.4. POSITIVE IMPACTS: The project would enhance the long-term productivity and well-being of the residents of Great Bend. Average annual flood control benefits would be $13.5 million. Mitigation measures would include replacement of 21 acres of riparian habitat, conservation of 56 acres of woodlands, revegetation of streambeds and banks, and construction of a pilot channel. NEGATIVE IMPACTS: Channelization of the Arkansas River would reduce fish habitat and populations and fishing opportunities. Levee construction would require terrestrial wildlife habitat and croplands. LEGAL MANDATES: River and Harbor and Flood Control Act of 1965 (33 U.S.C. 610).

AN - 36387816; 1369 AB - PURPOSE: This supplement to the final environmental impact statement of September 1975 deals with the reevaluation of advanced studies completed in August 1964 for a feature of the Yazoo Headwater Project: the Yalobusha River levees. The original recommendation was to construct levees along the east bank of the Yalobusha River below the south bank Teoc Creek levee to connect with the Big Sand Creek Diversion Channel levee. On the west bank of the stream, the plan included 6.7 miles of road-levee from Money to Whaley, Mississippi, continuing downstream 7.3 miles on the west bank of the Yalobusha River to connect with the Illinois Central Gulf Railroad embankment northeast of Greenwood, Mississippi. This original recommendation is no longer feasible; however, the reevaluation has revealed that enlarging a portion of the Yalobusha River would be feasible. Plan 8, the tentatively selected plan resulting from the reevaluation studies, consists of enlarging that portion of the river between river miles 11.6 and 21.4. The enlarged channel would have an 80-foot bottom width. Excavated material would be placed in confined disposal areas over top bank. Detailed analyses of fish and wildlife mitigation requirements would be made a part of the ongoing Upper Yazoo Basin Fish and Wildlife Mitigation Study. Proposed land acquisition for fish and wildlife purposes would be detailed in that separate mitigation report for congressional authorization. For purposes of these reevaluation studies, conceptual measures to compensate for terrestrial losses were developed. These measures include the purchase and management of 1,000 acres of bottomland hardwoods within the Yazoo Headwater Area. Maintenance activities would be a federal responsibility and would consist of maintaining the channel by means of a hydraulic dredge and would be done at project years 20 and 40. First costs of the plan would total $8.9 million, with annual costs of $475,000 and annual benefits of $2.1 million. The benefit-to-cost ratio would be 4.6. POSITIVE IMPACTS: The proposed plan would provide flood damage reduction benefits to lands generally adjoining the Yalobusha River between river miles 11.6 and 21.4. Flood stages and durations of overbank flows, and consequently agricultural damages, would be reduced. Average annual flood control benefits are estimated at $782,000. The construction plan would provide 51 skilled, 45 semiskilled, and 19 supervisory and administrative jobs for an extended period of time. Operation and maintenance would provide 87 jobs. The proposed plan would provide incentive for additional economic growth, with a positive impact on income. The increased agricultural output resulting from the flood protection would provide greater farm and agriculture business incomes throughout the project area. Other business and industrial activity in the surrounding areas would also increase. NEGATIVE IMPACTS: Approximately 607 acres of bottomland hardwoods would be lost over the life of the project, adversely affecting associated recreational values and wildlife species. Implementation of the plan would affect hydrologic conditions and approximately 64 acres of woodlands. Two known cultural resource sites would be significantly impacted by construction and maintenance. Noise would periodically be a nuisance, and ambient air quality would be degraded somewhat at times. Implementation of the plan would require relocation of several pipelines and powerlines.

An application is presented in which optimal reservoir flood control plans for a three reservoir system are selected. Computer program HEC-5 is used to simulate the reservoir system to determine the modified condition flow-frequency curves, EAD is used to evaluate expected annual damage reductions and the HEC-DSS Program was used to manage the large amounts of data required for the computations. The branch and bound enumeration algorithm provides a systematic evaluation of plans with the HEC programs and expedites identification of the optimal plan by elimination the need to evaluate all alternative plans.

AN - 36398265; 1343 AB - PURPOSE: Construction of a new location four-lane divided roadway, 25.35 miles in length, extending from State Route (S.R.) 316 and U.S. 29 northeast of Lawrenceville to S.R. 10/U.S. 78 west of Athens, Georgia is proposed. This arterial would be a partial limited-access facility, providing at-grade intersections with median crossovers at major crossroads. Other crossroads and driveways would be terminated or connected to frontage roads, where required for access into properties. It would be on a minimum of 300 feet of rights-of-way and would carry a design speed of 60 mph, 3-degree maximum curvature, and 3-percent maximum gradient. The extension would travel in an easterly direction on new location, would parallel the Colonial Gas Pipeline, and would then cross Dacula and Kilcrease roads south of Dacula. The roadway would cross Patrick Mill Road, S.R. 324, S.R. 81, S.R. 11, and S.R. 53 as it passes south of Fort Yargo State Park and north of the city of Bethlehem. This alignment would also pass through the southern portion of Statham and would cross S.R. 324 and Barber Creek Road before connecting with U.S. 78/S.R. 10 south of Bogart to its terminus. All major roads would be crossed at-grade. The estimated cost of the build alternative is $60.9 million. POSITIVE IMPACTS: Air quality would be in compliance with state and federal Ambient Air Quality Standards. Traffic would be reduced on parallel federal and state routes. The project would help reduce accidents on S.R. 8 /U.S. 29 and would improve vehicle efficiency for commuters and local users. NEGATIVE IMPACTS: Ten residences would experience noise levels in excess of noise abatement criteria. Traffic would increase on intersecting routes. Thirteen residences would be displaced, and six wetlands and some farmland would be impacted.

Preparation date: April 30, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RECOMMENDED PLANS FOR FLOOD CONTROL, COYOTE AND BERRYESSA CREEKS, SANTA CLARA COUNTY, CALIFORNIA. AN - 36387694; 1361 AB - PURPOSE: Plans for flood control on Coyote and Berryessa creeks in Santa Clara County, California are proposed. The lower Coyote Creek study area is located in the cities of San Jose and Milpitas in Santa Clara County, south of San Francisco Bay. Of the 12 preliminary structural and nonstructural plans considered, the Alternate Sides Overflow Channel and Offset Levees Plan for Coyote Creek is the preferred alternative. The plan would feature an overflow channel and offset levees set approximately 400 to 900 feet apart. The levees would vary between 4 and 9 feet in height, with a top width of 18 feet, and a side slope of 3 feet horizontal to 1 foot vertical (3H to 1V) on the inboard side and 2H to 1V on the outboard side. The width of the overflow channel would vary with geological and hydrological conditions. The plan would include hiking and bicycling trails and other recreational amenities to provide aesthetic quality and other recreational values on the east levee along Coyote Creek. It would mitigate for adverse environmental impacts, including fish and wildlife impacts, as well as other social effects. The plan has a benefit/cost ratio of 2.2; the first cost is presently estimated at $22.9 million. The Berryessa Creek study area is located in the cities of San Jose and Milpitas, California. The Trapezoidal Concrete Channel and Levee Plan has been tentatively selected as the recommended plan. Starting at the upstream project limit, approximately 600 feet upstream of Old Piedmont Road, the plan would feature a 500-foot by 160-foot (outside measurements) reinforced concrete-walled sedimentation basin with earth bottom that would undergo transition to a box culvert under Old Piedmont Road. A trapezoidal reinforced concrete-lined channel would lead out of the culvert and continue for almost 800 feet to the existing 400-foot-long box culvert under the intersection of Piedmont Road and Cropley Avenue. The bottom width would be eight feet, with side slopes of 1V to 2H. The trapezoidal channel would be constructed with a single service road on the east side of the creek to save the riparian vegetation that grows above the west bank. The plan would fully mitigate for adverse impacts to fish and wildlife and for other social effects; it has a benefit/cost ratio of 1.6 and a first cost presently estimated at $7.6 million. POSITIVE IMPACTS: The major beneficial impacts of the Coyote Creek plan are a reduction in future flood damages to existing public and private property and to business activities, enhancement of future land use, the incorporation of hiking and bicycling trails and related amenities, and a gain in floodway habitat considered to be more valuable to wildlife than the existing upland or agricultural land within the setback levee system. The major beneficial effects of the Berryessa Creek plan are a reduction in future flood damages to existing public and private property and to business activities and the enhancement of the Berryessa Creek Park and greenbelt. NEGATIVE IMPACTS: The major adverse effects of the Coyote Creek plan, for which mitigation measure are intended to compensate, are that it would cause the loss of 13.6 acres of riparian habitat along Coyote Creek, with the associated adverse impacts to fish and wildlife, degradation of aesthetic quality, the relocation of the Camp Coyote facilities at Agnews State Hospital, and the removal of three historic buildings. The major adverse impacts of the Berryessa Creek plan are removal of the riparian vegetation, for which mitigation measures are intended to compensate.

Preparation date: April 30, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BEACH EROSION CONTROL AND HURRICANE PROTECTION STUDY FOR DADE COUNTY, FLORIDA, NORTH OF HAULOVER BEACH PARK (SUPPLEMENTAL REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1975). AN - 36401917; 1362 AB - PURPOSE: Extension of a beach-erosion control and hurricane protection project in the vicinity of Miami Beach, Dade County, Florida is proposed. The originally proposed project involved placement of 14 million cubic yards of material to form a recreational beach and protective dune along 9.3 miles of shoreline between Government Cut and Bakers Haulover Inlet; the shoreline area would encompass Miami Beach, Surfside, and Bal Harbor Village. Periodic nourishment of the beach and dune also was planned. A subsequent study has indicated that modification of the existing project to provide for extension of the dune and beach by 2.5 miles north of Haulover Beach Park and for extension of federal participation in the cost of nourishment from 10 years to the entire life of the project is warranted. Material for beachfill and periodic nourishment would be obtained from borrow areas located 6,000 to 12,000 feet offshore. The cross-sectional configuration of the beachfill would consist of a 20-foot-wide berm at an elevation of nine feet above mean low water (mlw) with a seaward slope of 1 vertical to 10 horizontal to mlw, thence 1 vertical to 25 horizontal to the existing ocean bottom. Initial fill for the 2.5-mile extension would involve 1.5 million cubic yards of material, and periodic maintenance nourishment would require 715,000 cubic yards of material. This Supplemental Information Report documents the impacts of using aragonite (Oolitic sand) for initial fill and periodic renourishment for the 2.5 mile section of Dade County beach north of the north boundary of Haulover Beach Park. Local interests would construct 1,060 parking spaces and seven beach access points in association with the new beach. Initial cost of expansion of the beach and dune system is estimated at $7.9 million. Annual cost of the project is estimated at $961,000. The benefit-cost ratio of the expansion is estimated at 2.2. Annual cost of providing nourishment to the existing Dade County project is estimated at $555,000, while the benefit-cost ratio of continuing the existing project is estimated at 5.4. POSITIVE IMPACTS: The 2.5-mile extension would accommodate 25,300 beach visitors per day and provide protection from hurricane tides to commercial structures behind the dune system. Use of aragonite for initial fill and periodic nourishment would eliminate many of the adverse impacts on the offshore reef system. NEGATIVE IMPACTS: Benthic organisms at the offshore borrow sites and beach disposal sites would be destroyed, and the overall habitat of these areas would be altered. Suspended sediment would resettle on soft corals, damaging them to some extent. Material used to create and nourish the beach and dune system would be coarser than the existing beach material. Placement of sand could bury sea turtle nests, and crew boats could injure sea manatees navigating along the Atlantic Intracoastal Waterway; both of these species are listed as endangered.

MD Route 5 extends south from Washington, D.C. to Point Lookout at the southern tip of Maryland. The existing highway is a major north /south arterial for Prince George's, Charles, and St. Mary's counties and is used extensively for commuting to the Washington, D.C. area. The study portion of MD Route 5 begins just south of Washington, D.C. at the intersection of Beach and Oxford roads, continues under I-95 (Capital Beltway), and terminates at the existing interchange with U.S. Route 301. The existing six- and four-lane divided highway, with partial control of access, has numerous at-grade intersections. The study for the reconstruction of the highway includes the investigation of up to six new interchanges (excluding the MD Route 223 diamond interchange), the reconstruction of two existing interchanges (I-95 and U.S. Route 301), two upgraded intersections north of I-95, and up to four partial interchanges (right off-exit ramp and right on-entrance ramp). The interchange at MD Route 223 is presently in final design. The Build Alternative proposes (1) the reconstruction of MD Route 5 as a multilane facility, with the addition of one lane in each direction on the median side, to provide a total of six lanes and (2) the construction of up to six new interchanges to replace major at-grade intersections. Options are also under study for local access points north and south of the Capital Beltway/I-95 interchange, as well as at Allentown Road (MD Route 337), Surratts Road, and Burch Hill Road/Earnshaw Drive. In order to provide local access, right turns on and off Route 5 are proposed at several locations. The estimated cost of the project is $103.6 million. POSITIVE IMPACTS: The Build Alternative would result in improved traffic flow, controlled access, increased traffic capacity, and safety in the project area. The long-term effect on local businesses would be beneficial. NEGATIVE IMPACTS: The proposed plan would affect 142 properties, and would require that a total of 118 acres of land and four residences be relocated. Seven businesses would be displaced. Long-term environmental effects include the loss of 100 acres of woodlands and 52 acres of agricultural land and would encroach on 5.4 acres of floodplain and 8.5 acres of wetlands. Noise levels would increase marginally. Construction impacts include dust and noise associated with highway construction and potential erosion and siltation.

AN - 36403840; 1350 AB - PURPOSE: This draft supplement evaluates the effects of constructing an access road, which would begin on existing Oklahoma Highway 43 near the town of Daisy, in Atoka County, and would proceed easterly through Pittsburgh County to connect with State Highway 2 near the Sardis Dam (formerly named the Clayton Dam) and the town of Clayton, in Pushmataha County, Oklahoma. The travel distance between the two points would be 23.6 miles, shortening the old road some 4.0 miles on completion of all segments of the new highway. The new road would follow the alignment laid out by the state in 1963. New construction would begin near Daisy, approximately one mile east of the Indian Nations Turnpike and Oklahoma Highway 43 interchange. From this point, proposed relocation of Highway 43 would consist of approximately 16.6 miles of grading, drainage, and surfacing. The Stage I P-6 segment of construction, already completed, consists of minor reshaping of an existing roadbed to obtain a 32-foot-wide compacted subgrade. An 8-inch-thick aggregate base course, 24-feet wide, was placed and surfaced with 2-inch-thick asphaltic concrete 22-feet wide. Construction was completed with the addition of two 4-foot-wide turfed shoulders. The remainder of Stage I construction consisted of light grading along an old roadway connecting segments P-6 and P-3 to obtain a 32-foot-wide subgrade, replacing two minor drainage structures, and surfacing to match the P-6 segment. Stage II construction would begin on existing Oklahoma Highway 43 near the town of Daisy and run easterly to connect with the Stage I construction. A short segment of new roadway, designated P-3 extension, is also included in this stage. Proper signing, striping, connecting ramps, fencing, detours, and erosion control would also be part of the Stage II construction. Enabling legislation requires that the state accept ownership and operate and maintain the completed facility. The estimated construction cost is $10 million. POSITIVE IMPACTS: The new road would greatly reduce the time needed for trips from the Indian Nations Turnpike and areas from the west to reach Sardis Lake. Construction of the road would most likely enhance growth and development in the project area in the form of residential and highway service businesses. NEGATIVE IMPACTS: Construction of the project would require displacement of people and removal of lands from private ownership. An additional 240 acres of rights-of-way would be needed to construct the proposed project. The most significant impacts would be the direct loss of 20 acres of stream bank vegetation, primarily bottomland forest. Cut and fill operations would create an unvegetated strip across the drainages, removing an additional 137 acres of upland forest and 80 acres of grassland. Until the newly constructed areas are revegetated, exposure to natural elements would create erosion, resulting in a major source of water pollution. The aquatic ecosystem of the streams crossed by the road would be subjected to direct, short-term impacts of construction. Wetlands impacted by the new road would include six ponds and three streams of the temporarily flooded palustrine broadleaved forest type and one stream of the seasonally flooded type. The long-term impacts would be loss of high quality habitat resulting in a displacement of the wildlife communities. The highway would also act as a barrier to wildlife trying to move from one side of the road to the other. LEGAL MANDATES: Executive Order 11990.

Preparation date: April 24, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - OYSTER SHELL DREDGING IN ATCHAFALAYA BAY AND ADJACENT WATERS, LOUISIANA. AN - 36394999; 1367 AB - PURPOSE: Impacts of oyster shell dredging in East Cote Blanche Bay, Atchafalaya Bay, and Four League Bay, Louisiana, as permitted under 5-year permits issued in 1982 and expiring in December 1987, are assessed. The impacts of applications for 10-year time extensions that would allow the continuation of dredging under the same conditions are also accessed. Oyster shells have been removed by means of hydraulic cutter-head dredges from the waters of coastal Louisiana since 1917. The shells have been harvested primarily for use in construction activities, although a variety of other uses is common. Five alternatives are presented: (1) renew permits with existing conditions; (2) deny permits (no action); (3) renew permits with existing conditions, but close the bottom half of Four League Bay to dredging activities; (4) renew permits with existing conditions but reduce the width of the zone restricting dredging near the shore in the upper half of Four League Bay from 0.5 mile to 1,500 feet; and (5) renew permits with existing conditions, but reduce the dredging intensity to allow a maximum of two dredges in western East Cote Blanche Bay. POSITIVE IMPACTS: The holes and troughs that result from the removal of buried oyster reefs may provide a place for refuge for fish during the passage of cold fronts. The major economic impacts extend throughout the coastal area. Shells provide the most economical source of aggregate for roads in coastal Louisiana. Shell dredging also provides jobs and income, and royalty and severance taxes collected by state agencies are used to provide public services. The most beneficial social impacts of shell dredging are those related to community cohesion and community growth. NEGATIVE IMPACTS: The primary effect of shell dredging on water quality is a temporary increase in turbidity and suspended solids levels. At the current rate of dredging, there are only 2.1 years of shell dredging activity in the area of East Cote Blanche Bay and 2.0 years in Atchafalaya Bay. Each working dredge would directly disturb approximately 1.2 acre of shallow waterbottom per day. Dredging of buried shells has the most dramatic impact on the benthic animals whose existence is dependent on the sediments. Two negative social impacts are increased noise and turbidity found around the dredge.

Preparation date: April 24, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE LOCATION ADOPTION AND CONSTRUCTION OF STATE ROUTE 52 BETWEEN SANTO ROAD IN THE CITY OF SAN DIEGO AND STATE ROUTE 67 IN THE CITY OF SANTEE, SAN DIEGO COUNTY, CALIFORNIA. AN - 36386889; 1341 AB - PURPOSE: Adoption of a route location and construction of a freeway from the east end of the previously adopted portion of State Route (SR) 52 near Santo Road in the city of San Diego to SR 67 in the city of Santee, San Diego County, California are proposed. From Santo Road to the intersection with future SR 125, the Fortuna Alternative route would include a six-lane freeway (four lanes of initial construction), full interchanges at Santo Road and Mast Boulevard, a half-diamond interchange at Mission Gorge Road, provisions for future interchanges at Jackson Drive and Spring Canyon, and bridge structures at Oak Canyon, Spring Canyon, and the San Diego River. The first usable portion of the Fortuna Alternative would be from Santo Road to Mast Boulevard (4.9 miles). This initial four-lane facility could be constructed for $65 million. The total six-lane alternative cost from Santo Road to SR 125 would be $119 million. East of SR 125, two alternatives would cross the city of Santee and end at SR 67; they are the River and Prospect alternatives. The Prospect Alternative would traverse through the southern part of Santee and, in general, would be 500 feet north of the parallel to Prospect Avenue. This alternative approximates one of the freeway alignments shown in the Circulation Element of the Santee General Plan. The segment would 2.5 miles long; the estimated cost is $89 million. The River Alternative would traverse through the central part of Santee and, in general, would follow the southern edge of the San Diego River floodway and intersect SR 67 at the existing Woodside interchanges. This alignment would impact Santee's proposed Town Center, and is opposed by the City Council. The estimated cost for this 2.8-mile segment is $121 million. Total costs for the combined alternatives are Fortuna/Prospect $208 million and Fortuna/River $240 million. POSITIVE IMPACTS: The proposed project would provide direct access between east county communities and job centers in the city of San Diego's north/west section. It would relieve traffic on Interstate (I) 8 and on local streets, and would improve the transportation network flow by connecting north/south routes of I-5, I-15, I-805, and SR 67. NEGATIVE IMPACTS: Five environmental effects are unavoidable and cannot be mitigated below the significant level. These include visual, land use, open space, residential displacement, and noise impacts. The Fortuna /Prospect alternative would impact a total of 13 visual aspects, 1 of which could not be mitigated below significance; 450 acres of land, 415 of which could not be mitigated below significance; 310 acres of open space, 235 acres of which could not be mitigated below significance; and 535 dwellings, including 275 mobile homes. The Fortuna/River alternative would impact a total of 15 visual impacts, 2 of which could not be mitigated below significance; 456 acres of land, 420 of which could not be mitigated below significance; 340 acres of open space, 265 acres of which could not be mitigated below significance; and 415 dwellings, including 230 mobile homes. More than half of the relocatees in either alternative are estimated to be seniors. Relocation effects, therefore, are not considered to be mitigated below significance. Many of the noise receptors could have a potentially significant increase. Most can be mitigated below significance; however, up to 60 receptors on either Fortuna/Prospect or Fortuna/River would not be mitigated below significance from a cumulative perspective, but not on an individual basis. Adverse impacts subject to mitigation include impacts on vernal pool habitat, least Bell's vireo habitat, and riparian and animal habitat.

Preparation date: April 24, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD PROTECTION FOR THE UPPER JORDAN RIVER BASIN, SALT LAKE COUNTY, UTAH. AN - 36380835; 1370 AB - PURPOSE: A plan for flood control for the Upper Jordan River, Utah is proposed. The Upper Jordan River reach under study extends from Jordan Narrows to 2100 South Street in Salt Lake County, Utah. Mill Creek, Big Cottonwood Creek, and Little Cottonwood Creek are major tributaries of the Jordan River within this reach, each with headwaters in the Wasatch Mountain Range. Each creek passes through different portions of the expanding urban and residential development of suburban Salt Lake City. Floods have been a recurring problem along each of these creeks and the Jordan River. The purpose of this environmental impact statement is to describe the impacts of the proposed flood control plan on Mill Creek. The plan selected for potential implementation includes flood control features on upper Mill Creek that would complement existing and planned local flood control improvements. The major features include a diversion dam, located approximately 200 feet above Highland Drive, and a 7,440-foot-long, 90-inch-diameter conduit and a 74-acre-foot enlargement to the Hillview Detention Basin. The diversion dam is designed to bypass Mill Creek flows up to 200 cubic feet per second (cfs) to the existing stream channel and to divert up to 750 cfs into the conduit for conveyance to the Hillview Detention Basin. The diversion dam would be a gated concrete structure having a width of approximately 55 feet and an overall length of 155 feet including transition sections. A side channel flume would direct the diverted flows into the conduit. Diversions would be regulated by a manually operated slide gate. The conduit extending from the diversion structure to the Hillview Detention Basin would be reinforced concrete and would be placed under public streets. The conduit would outlet into the Hillview Detention Basin. The Hillview Detention Basin would initially be constructed by local interests to a capacity of approximately 26 acre-feet to regulate floodflows collected and conveyed by a local storm drain system. As a part of the project plan, the detention basin would be enlarged by 74 acre-feet to provide a total storage area of 200 acre-feet. Controlled release from the basin would be made through a storm drainage system into Big Cottonwood Creek. To reestablish wildlife populations that may become dislocated during construction, the detention basin would be revegetated. The estimated first cost of the project is $7.4 million, with a benefit-to-cost ratio of 1.3. POSITIVE IMPACTS: The selected plan would provide reduced flood hazards, with 100-year flood protection provided to most of the Mill Creek floodplain. NEGATIVE IMPACTS: The plan would result in a loss of 0.3 acre of vegetation at the diversion site and loss of upland vegetation at the detention basin. There would be minor short-term disturbance of fish habitat during construction, with little or no change to other wildlife. Temporary increases in noise, traffic congestion volumes, and local concentrations of air pollution contaminants would occur as a result of construction activities.

Preparation date: April 24, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TACONIC STATE PARKWAY, HAWTHORNE INTERCHANGE TO CAMPFIRE ROAD, WESTCHESTER COUNTY, NEW YORK (P.I.N. 8003.20). AN - 36405975; 1349 AB - PURPOSE: Reconstruction of 4.9 miles of Taconic State Parkway between Hawthorne Interchange and Campfire Road within the towns of Mount Pleasant and New Castle in Westchester County, New York is proposed. The parkway would be reconstructed to a six-lane divided roadway, with the proposed southbound lane using the existing parkway alignment. The present at-grade connections of Washburn, Old Chappaqua, and Campfire roads would be eliminated. A partial interchange would be provided between Route 117, Routes 9A/100, and the parkway, and a full interchange is proposed at Pleasantville Road. East of the parkway, Chappaqua Road would be relocated between Pleasantville and Washburn roads, and Washburn Road, west of the parkway, would be dead ended. A grade separation would carry the parkway over Old Chappaqua Road. Route 117, between the Route 448 intersection on the west and the Manville Road intersection on the east, would be rebuilt under the proposed action, known as "Route 117, Alternate 1 Modified." Directly east of the parkway ramps, Route 117 would consist of two 12-foot lanes eastbound up to Pace University entrance drive. Westbound from the entrance drive, one 12-foot lane widens to two 12-foot lanes plus an auxiliary 12-foot left-turn lane at the parkway ramp. East of Pace University, to the Choate Avenue intersection, Route 117 gradually tapers to one eastbound and one westbound 11-foot through lane, a 10-foot turn lane, and 1-foot curb offsets, for a total width of 34 feet. This lane configuration would continue to the Manville Road intersection. Bedford Road would be treated as a through road. West of the parkway, Route 117 would be reconstructed as four 12-foot lanes. The proposed action would extend Campfire Road to Route 100 on the east side of the parkway on a new alignment, which would be generally parallel to the parkway. A significant portion of the proposed extension would use the abandoned railroad rights-of-way in the area. POSITIVE IMPACTS: Provision of access control via interchanges and separation structures and widening of the facility from four to six lanes would improve efficiency and enhance safety on a major regional highway. Access to communities in northern Westchester and Putnam counties would be improved, and commuting time between these communities and New York City would decrease. Improvement of the segment would complete conversion of the parkway into a six-lane freeway. There would be a net increase of 1.2 acres of enhanced wetlands. NEGATIVE IMPACTS: Rights-of-way requirements would displace 54 acres, including 27 acres of park and recreational land and up to 18.2 acres of wetland. Two residences would be displaced. Gas, water, sanitary sewer, electric, and telephone utilities would require relocation during the construction phase. Traffic increases along the route would result in increased levels of noise and air pollutants. Noise levels affecting some receptors would exceed Federal Highway Administration standards.

Preparation date: April 22, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CLAM SHELL DREDGING IN LAKES PONTCHARTRAIN AND MAUREPAS, LOUISIANA. AN - 36394954; 1366 AB - PURPOSE: The impacts of clam shell dredging in Lakes Pontchartrain and Maurepas, Louisiana, as permitted under 5-year permits issued in 1982 that will expire in December 1987, are assessed. The impacts of applications for 10-year permit extensions that would allow shell dredging to continue under the same conditions are also assessed. Applicants for the permits and extensions are Dravo Basic Materials Company, Inc., Pontchartrain Materials Corporation, and Louisiana Materials Company, Inc. Clam shells (Rangia) have been harvested from the lakes area since 1933 by means of hydraulic dredges. The shells are used primarily in construction and maintenance activities, but have a variety of other uses as well, such as in the construction of roadways, parking lots, drill pads, and levees and in the production of cement. The alternatives considered include (1) permit denial; (2) permit renewal with existing conditions (applicant's proposal); (3) permit renewal with additional restrictions on areas available for dredging, dredging intensity, and dredge discharge; and (4) permit renewal with reduced restrictions on areas available for dredging, dreging intensity, and dredge discharge. Based on a thorough analysis of the alternatives, it was determined that alternatives (1) and (2) should be investigated in detail. Permit denial would require all shell dredging activities to cease. As part of the analysis under this alternative, other materials that could be used instead of shells are being investigated. Alternative 2, the proposed alternative, assumes that shell dredging activities would continue as currently permitted and regulated. POSITIVE IMPACTS: Recent estimates indicate that the gross value of shells harvested from the lakes area is approximately $34 million annually. The shell-producing companies provide local employment and income, which is particularly significant due to the area's recent economic downturn. Royalties and severance taxes collected by the state are used to provide public facilities and services. Shell dredging as currently authorized would help sustain the current community structure. NEGATIVE IMPACTS: It is well documented that shell dredging causes a temporary localized increase in turbidity and levels of total suspended solids in the immediate vicinity of the operating dredge. These turbidity impacts are significant in Lake Maurepas, and it is suggested that the dredging may be responsible for the apparent long-term increase in turbidity in Lake Pontchartrain. Shell dredging has played a major role in the decline of large Rangia and in other changes in the benthic community.

Preparation date: April 22, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - U.S. BORAX MOLYBDENUM CLAIMS AT QUARTZ HILL, TONGASS NATIONAL FOREST, ALASKA (REVISED DRAFT ENVIRONMENTAL IMPACT STATEMENT). AN - 36399355; 1334 AB - PURPOSE: The construction and operation by U.S. Borax and Chemical Corporation of a nominal 80,000 ton-per-day (tpd) molybdenum mine and processing facility at the Quartz Hill site, 45 miles east of Ketchikan, Alaska, in the Misty Fiord National Monument of the Tongass National Forest, is proposed. The Tongass National Forest is the last substantially intact temperate rainforest on Earth. This revised draft EIS addresses the environmental impacts of the construction, operation, and post-mining abandonment of a mine, mill, and associated facilities at the Quartz Hill site, as specified in the draft EIS. Significant issues include impacts of project water supply on area watercourses, tailings disposal impacts, fisheries habitat protection, worker housing and possible impacts to Ketchikan, water quality protection, impacts of project activities on wildlife and habitats, and protection of adjacent wilderness area values. The mine development project would consist of an open-pit mine, waste rock disposal areas, ore crushing and transport, a concentrator, tailings transport and disposal, employee housing, and support facilities such as roads, water supply, wastewater treatment, and power supply. Nine alternatives, including a No Action Alternative (Alternative 1), are considered in this revised draft EIS. The proposed action would include a mill at Tunnel Creek, marine tailings disposal in Wilson Arm, and workers living at single-status housing at the project site and commuting during days off to Ketchikan. Alternative 2 would include Tunnel Creek Mill with Boca de Quadra tailings disposal and either a commute option or a townsite at Bakewell Arm or at one of two sites near the mouth of the Wilson River. Alternative 3 would include Tunnel Creek Mill with Wilson Arm tailings disposal and a townsite. Alternative 4 would include Beaver Creek Mill with Boca de Quadra tailings disposal and either a townsite or commute. Alternative 5 would include Beaver Creek Mill with Wilson Arm tailings disposal and either a townsite or commute. Alternative 6 would include Beaver Creek Mill with on-land tailings disposal and either a townsite or commute. Alternative 7 would include North Meadow Mill with Boca de Quadra tailings disposal and either a townsite, including the possibility of a site near the mouth of the Keta River, or commute. Alternative 8 would include North Meadow Mill with on-land tailings disposal and either a townsite or commute. Several subalternatives also are under consideration. The Forest Service's (FS's) preferred alternative for mine development would locate the ore processing facilities in Tunnel Creek valley, generate electric power for the mine on-site, disallow creation of a townsite, access the mine along the route of the existing bulk sample access road, and obtain processing water from an impoundment on Tunnel Creek. When the mine production was increased from the initial 40,000 tpd capacity to 80,000 tpd, the water supply could be supplemented from a location near the mouth of the Blossom River. If necessary, a weir could be built to prevent saltwater intrusion into this supply. Anadromous fish passage would be assured in the design of this structure. Water withdrawals from the Blossom River would be managed so that an instream flow would be maintained sufficient for present and continued productivity of fish habitat. The FS's preferred alternative for tailings disposal would be marine disposal in the Wilson Arm. The Environmental Protection Agency (EPA) concurs with the FS preferred alternative with one exception. The EPA has concluded that the middle basin of Boca de Quadra is the environmentally preferred location for mill tailings disposal. POSITIVE IMPACTS: The Quartz Hill project would supply molybdenum to U.S. and free world markets, with a positive impact on the nation's international trade. New employment, both direct and indirect, for approximately 1,800 persons at the peak construction level and approximately 2,000 persons during project operations would be required. The economies of the Ketchikan Gateway Borough and the region would receive benefits from the approximately $54 million in annual wages generated by the project. NEGATIVE IMPACTS: Dust emissions from the mine and sulfur dioxide emissions from a power plant could exceed state air quality standards. The hydrologic regime of virtually all of White Creek, and substantial portions of Hill and Beaver creeks, would be essentially eliminated by development of the waste rock dumps and the open-pit mine. Water quality would be adversely affected by increased sediment loads, particularly during construction. Blasting noises in the wilderness area of Misty Fiords National Monument could disturb mountain goat populations. Avalanche danger in the project area would be high. Adverse impacts on freshwater fisheries would be relatively minor. Marine tailings disposal could adversely affect herring. Vegetation would be cleared from approximately 2,900 acres for project construction. Construction of the proposed wharf would eliminate one bald eagle nest. Some public services and facilities would be overloaded. Visual changes would result from the introduction of an industrial facility into a natural area.

Preparation date: April 20, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD DAMAGE REDUCTION MEASURES, UPPER CUMBERLAND RIVER BASIN, HARLAN, BAXTER, LOYALL, AND RIO VISTA, KENTUCKY. AN - 36380761; 1365 AB - PURPOSE: Flood control measures are proposed to reduce flood damage in the Upper Cumberland River Basin, located in Harlan, Baxter, Loyall, and Rio Vista, Kentucky. These measures should be sufficient to prevent any future losses resulting from floods equivalent to that which occurred in 1977. Six alternative plans, including that of no action, were analyzed. The recommended plan includes diversion channels at Harlan and Loyall requiring the excavation and subsequent disposal of 9.3 million cubic yards (mcy) of material; floodwalls and levees totalling approximately 14,000 feet in length; forced relocation of approximately 140 residences and 5 nonresidences; floodproofing 158 residences and 31 nonresidential structures; and evacuation and resettlement of 80 residences, 42 nonresidential structures, and 35 mobile homes. The plan would specifically utilize two major diversion channels in combination with floodwalls and levees to provide Standard Project Flood (SPF) protection levels to the communities of Loyall and Rio Vista and the Harlan central business district. Areas outside the levee /floodwall systems would receive April 1977 flood levels of protection through applications of nonstructural measures. The Harlan diversion channel would divert the Clover Fork flows around the city of Harlan. This channel would be approximately 3,000 feet in length, reach a maximum depth of 430 feet, and require removal of 5.8 mcy of material. The Loyall diversion channel would divert the Cumberland River flows around the city of Loyall. The channel would be 3,800 feet long, reach a depth of 300 feet, and require removal of 3.5 mcy of material. The diversion channels alone would not provide the required flood protection, therefore, approximately 4,000 linear feet of floodwall would be required along highway 421 at Harlan, as well as levee/floodwalls at the entrances to each diversion. A levee would also be required around the perimeter of Rio Vista. The total estimated project costs are approximately $120 million. POSITIVE IMPACTS: The recommended plan would greatly reduce or virtually eliminate flood losses such as those that occurred in 1977. Beneficial impacts to water quality would occur from the removal of point source discharges in conjunction with the nonstructural evacuations and forced evacuation from structural components. Long-term adverse impacts to aquatic resources would be minimized by including instream structures, riparian zone replacement, and other environmentally designed features. The future socioeconomic outlook of the involved communities would be enhanced, and excavated material could be judiciously used to develop flood-free parcels for urbanization. NEGATIVE IMPACTS: Adverse impacts would occur from diverting and filling 27 acres of river; siltation from erosion of disturbed areas until stabilized; possible leaching of such metals as iron, aluminum, and magnesium from disposal areas and cut slopes; and runoff from the road to be constructed within the Loyall diversion channel. The recommended plan would have the most adverse geological impact, since 9.3 mcy of soil and rock would be excavated to create the diversion channels, and would require the second largest amount of compacted fill for levee/floodwall construction. Approximately 289 acres of terrestrial resources would incur long-term adverse impacts or destruction, including prime farmland, upland and cove forest, scrub, and riparian zones. Wildlife would be disturbed by construction activity, change in habitat type, and loss of land. There would be some short-term impacts from dust and emissions. Backfilling old channels would cause temporary high concentrations of particulate matter in densely populated areas. Hunting and fishing would be affected due to diversion/filling and disposal activities. The structural element would relocate 140 households and would evacuate 5 nonresidential structures. In the nonstructural component, 273 structures would be involved. Approximately 400 people would have to be moved.

Preparation date: April 17, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MAINTENANCE OF BLACK WARRIOR AND TOMBIGBEE RIVERS, ALABAMA (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF APRIL 1976). AN - 36400613; 1359 AB - PURPOSE: Implementation of a maintenance plan for the Black Warrior and Tombigbee (BWT) rivers, Alabama is proposed. The BWT Waterway provides for a channel 9 feet deep and 200 feet wide, extending from the mouth of the Tombigbee River 45 miles above Mobile to the vicinity of Birmingham, a total waterway distance of approximately 463 miles. This final supplement to the final environmental impact statement describes the planned operation and maintenance of this system through the year 2005. The proposed plan was formulated to include practices that may be necessary to maintain the waterway during the next 20 years. Each individual component of the plan might not necessarily be implemented, depending on the dynamic nature of the river system. The proposed plan includes the following: (1) construction of training dikes at Coffeeville Lock and Dam and in the Buena Vista dredging reach; (2) expansion of the dredging reaches from the 52 miles presently approved to a total of 87 miles; (3) increasing the within-banks disposal areas from the 69 miles presently approved to a total of 122 miles; (4) provision of additional diked upland disposal areas of approximately 926 acres in addition to the 1,161 acres presently being used, with mitigation measures via effective management practices on government lands directed toward offsetting bottomland hardwood losses; (5) increasing the number of small-boat access channels that could be maintained; and (6) alleviation of the navigational hazard at the Southern Railroad Bridge at Jackson, Alabama and reduction of annual dredging quantities by maintaining the flow through this reach of the river. POSITIVE IMPACTS: The general operation and maintenance plan would provide for the continued use of the project and would enhance recreation, fish, and wildlife resources wherever possible. It is projected that dike fields on the BWT would produce habitat enhancement for both macroinvertebrates and fish. The 3,000-foot longitudinal dike on the left-descending bank would provide increased surface area for organism attachment and increased fish food organisms. The dikes would have the additional benefit of maintaining boat access to the severed bendway. Creation of sandbars would provide additional recreation sites. NEGATIVE IMPACTS: The seven training dikes and the area in between each dike would cover an area of 14.9 acres of existing river bottom, thus destroying the benthic communities presently colonizing this area. The most significant impacts of diked upland disposal practices would be the loss of 314 acres of bottomland hardwood habitat. An estimated 482 acres of productive pasture- or cropland would be lost and, unless the sand is removed, would remain nonproductive for agricultural uses. The construction of the training dikes would result in temporary increases in noise and air pollution levels, turbidity, and a temporary reduction in the photosynthetic rate. Benthic communities would be destroyed in the areas dredged for small boat channel maintenance and on aquatic disposal sites, and fish habitat would be disrupted on a short-term basis. Since all proposed upland disposal areas are within the floodplain of the river, there is a potential for erosion of the dikes surrounding the area; during flood conditions, the water flowing out of the river banks could cause dike erosion resulting in the deposition of material within the disposal area onto terrestrial habitat or back into the river.

Preparation date: April 15, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GARAPAN FLOOD CONTROL PROJECT, SAIPAN, NORTHERN MARIANA ISLANDS. AN - 36406074; 1368 AB - PURPOSE: Flood control measures are proposed for the village of Garapan, on the island of Saipan, in the Commonwealth of the Northern Mariana Islands. The total length of channel improvements for the preferred alternative would be 5,960 feet. The interceptor channel would have a 15- to 20-foot base width, and the outlet channel base would be 20 feet wide. The plan provides for ditches and spillway inlets to convey upland flows to the interceptor channel. The invert elevation for the outlet channel at the shoreline would be 4 to 6 feet. The project would be designated so that flows would be one directional from a southwesterly to a northwesterly direction. The diversion channel would start from between 3rd and 4th streets at the south end, extend northeasterly on the east side of West Coast Highway, and go around the American Memorial Park wetlands to the ocean. Culverts would have to be constructed along the channel alignment at six road crossings, and utilities would have to be relocated at these structures. The six crossings include the Beach Road, Micro Beach Road, new Hospital roads 1 and 2, Paganville Road, and Island Power Road. Flows from the interceptor channel would pass through culverts to be located at the Micro Beach Road and the West Coast Highway intersection. The channel receiving flows from the culvert would extend through the wetlands between the ocean and the Micro Beach Road and West Coast Highway intersection and would be trapezoidal, with a base width of 20 feet and side slopes of 3 horizontal on 1 vertical. The plan would allow a portion of the stormwater conveyed by the flood control channel to flow into the wetlands. The total project first cost is estimated at $6.8 million, with a benefit-to-cost ratio of 1.04. POSITIVE IMPACTS: The recommended plan has the largest net economic benefits of all the plans considered. The project would reduce ponding conditions and sheet-flow flooding in lower Garapan. This may decrease health hazards associated with overflowing cesspools, failure of sewer pump stations that sometimes occur during flooding, and the presence of pest insects. Land use and property values in the protected floodplain should rise, and the plan would permit current open spaces to be developed for additional housing or commercial purposes. NEGATIVE IMPACTS: The project would have temporary and long-term effects on coastal water quality. The outlet channel would intercept and divert sheet-flow runoff from elevated areas east of the American Memorial Park wetland that would normally flow into the wetland during high rainfall conditions. Increased sediment discharges and salinity regimes in the vicinity of the outlet channel might encourage expansion of mangrove trees along the lagoon shoreline. The proposed plan would remove a limited amount of habitat for the Nightingale Reed Warbler. The project would pass directly through a proposed sports field complex.

AN - 36400565; 1324 AB - PURPOSE: Implementation of a flood control plan for the Passaic River Basin in all or parts of Passaic, Bergen, Morris, Essex, Sussex, Hudson, Union, and Somerset counties in New Jersey and Rockland and Orange counties in New York is proposed. The recommended flood management plan for the basin, referred to as the Dual Inlet Tunnel Plan, is designed to protect against flooding, ranging from 100- to 500-year events intermittently, depending on locations. This plan would require a 13.5-mile-long, 39-foot-diameter tunnel between Wayne and Clifton, New Jersey and a 1.2-mile-long, 22-foot-diameter tunnel spur with an inlet at Two Bridges to convey floodwaters from an inlet just below the Passaic River-Pompton River confluence to an underground connection with the main diversion tunnel. Some 5.9 miles of channel modifications would be required to direct the flows into the inlet intake structures, and the diversion tunnels would be augmented by 23.6 miles of levees and 13.7 miles of floodwalls. The tunnels would be entirely underground, ranging from 125 to 450 feet under the surface. Structural flood control measures would be required to direct flood flows into the inlet. A major nonstructural component, preservation of 5,350 acres of natural storage, including 5,200 acres of wetlands, is also included. POSITIVE IMPACTS: All sites within the 100- to 500-year floodplains would be protected. Transportation delays as a result of flooding would be eliminated, property values would increase, and the habitat of endangered species would be protected. The shoreline would be cleaned, but access for recreation would be present only at selected points. Examination of the area might result in possible discovery of new prehistoric sites. NEGATIVE IMPACTS: Two acres of riverine flats at the tunnel outfalls and a total of 10 acres of wetlands in the Little Falls area would be lost, with a total wetlands loss of 150 acres. Construction and maintenance would affect fisheries. Temporary increases of noise and traffic delays would also be experienced during construction.

AN - 36398427; 1308 AB - PURPOSE: Reconstruction and improvement of a 12-mile segment of U.S. 50 from just east of Cimarron to Windy Point in Montrose and Gunnison counties, Colorado are proposed. The project improvement involves upgrading the existing alignment along its current location, with minor shifts in location on the curvature, or provide better alignment. The new roadway would consist of two 12-foot driving lanes, 8-foot paved shoulders, and a climbing lane where necessary. Blue Creek Canyon on the east end of the project would require some heavy construction and crossing of and minor encroachments into the Blue Creek floodplain, as well as some sidehill rock cuts. Encroachments into Blue Creek itself would be minimized by the extensive use of retaining walls and cantilevered bridge structures. POSITIVE IMPACTS: The improved roadway would replace a deteriorating roadway characterized by narrow lanes, a low allowable driving speed, and poor sight distances. The new roadway would be able to handle the expected future increases in traffic volumes on the route, which would cause severe congestion problems if the current highway is left as is. The project would decrease the cost of maintaining this segment of the highway. NEGATIVE IMPACTS: Rights-of-way requirements would result in the loss of 118 acres of habitat and irrigated rangeland. Acquisition of rights-of-way would decrease county tax bases. Enlargement of the highway through Blue Canyon would degrade the visual quality of the canyon. Nine of the 13 archaeological sites identified in the corridor as eligible for inclusion on the National Register of Historic Places could be damaged.

AN - 15227013; 1307 AB - PURPOSE: Reconstruction of 11.3 miles of Colorado Forest Highway 26 (State Highway (S.H.) 7) from the northern end of the community of Meeker Park to the junction of the highway and U.S. 36 in the town of Estes Park, Colorado is proposed. The project would traverse Boulder and Larimer counties. The existing two-lane facility, which has 11-foot lanes, would be improved and, in urbanized areas of Estes Park, expanded to four lanes. Specifically, the project would involve construction of two 12-foot lanes with 8-foot shoulders from Meeker Park to Wind River Pass (Tahosa Valley), a distance of 4.5 miles; construction of two 12-foot lanes with 6-foot shoulders and one or two 2,500-foot climbing lanes from Wind River Pass to Bottom of the Switchbacks, a distance of 3.3 miles; construction of two 12-foot lanes with 8-foot shoulders from Switchback to Estes Park, a distance of 1.5 miles; construction of two 12-foot lanes with 8-foot shoulders, a continuous 14-foot center lane, and a 6-foot bike path from the Estes Park town limit to Lexington Lane; and construction of four 11-foot lanes with a continuous 14-foot center turn lane and a 6-foot bike path from Lexington Lane to U.S. 36, a distance of 0.9 mile. Parking pulloffs would be provided at scenic view points, and parking areas would be provided at the Twin Sisters, Storm Pass, and Lilly Mount trailheads. Four horse underpasses would be installed at high-use horse trail crossings, if design studies indicated that these were warranted. POSITIVE IMPACTS: Reconstruction of the highway would improve an integral part of the state and forest highway systems, ease travel along this scenic route through the Roosevelt National Forest and Rocky Mountain National Park, and complete improvement of S.H. 26. Access between the towns of Lyons and Estes Park would be improved significantly. NEGATIVE IMPACTS: Development of additional rights-of-way for the project would displace 1.3 acres of wetland, encroach laterally on 15 to 30 feet of floodplains of several minor creeks along the corridor, convert 70 acres of mountain forest and other vegetation to road use, and result in the loss of 0.14 acre of Meeker Park Camground. Thirty-one noise sensitive sites would be exposed to traffic-generated noise; noise barriers at 14 of these sites would not significantly reduce ambient noise levels.

Preparation date: April 3, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RESTUDY OF THE EXISTING DENISON DAM, LAKE TEXOMA PROJECT, OKLAHOMA AND TEXAS. AN - 36395175; 1292 AB - PURPOSE: Restudy of the Denison Dam-Lake Texoma project was accomplished to determine whether the existing project should be modified to satisfy present and projected water resource problems and needs. The Denison Dam is located approximately five miles northwest of Denison, Texas. Lake Texoma, an 88,000-acre impoundment on the Red River, lies in both Texas and Oklahoma. Specific attention was directed toward flood control, hydropower, water supply, irrigation, recreation, fish and wildlife resources, cultural resources, navigation, regulation of the Red River flow, sedimentation, and construction of a highway bridge over the Big Mineral Arm of the lake. Study results indicated a need for additional hydroelectric generating units. In addition, there is a need to retain the existing flood control capability, provide additional recreation facilities, improve existing fish and wildlife habitat, and recover valuable endangered cultural resources. The addition of up to three generating units at the unused power penstocks would provide the best opportunity to increase the project's power output. If the addition of new generating units is undertaken, the upgrading of the two existing units could be incorporated with a plan to add new units so as to further enhance the total plant output. Plans were developed to change the upper or lower limits of the conservation pool. These plans could help to meet the need for more electric power generation and the need perceived by local recreation interests for higher and more stable pool levels for recreation. Periodic sediment surveys indicate that methods currently being used, such as better farming methods and the construction of small lakes and ponds in the upper basin for soil conservation purposes, are working and are expected to further decrease sediment deposits in Lake Texoma. Preliminary designs and cost estimates for plans to add one, two, or three generating units are included in the report to document the preliminary designs used as a basis for cost estimates. Estimated first costs for these plans at October 1986 price levels are $28.2 million, $52.3 million, and $76.2 million, respectively. The analysis of the plans indicated that none were economically feasible based on benefits and costs; however, there is significant nonfederal interest in financing the addition of up to three hydroelectric generating units at the project. For this reason, the potential environmental impacts of a plan to add up to three generating units were documented. POSITIVE IMPACTS: The benefits to be derived were evaluated by computer modeling the operation of the added unit(s), together with the two existing units in three alternative powerplant configurations (3, 4, or 5 units). Hydropower operations were modeled with 150,000 acre-feet from the conservation pool reserved for water supply. Total annual benefit values range from $2.8 million to $6.4 million, with benefit-to-cost ratios ranging from 0.9 to 0.8, respectively. NEGATIVE IMPACTS: Adverse environmental impacts that could not be avoided are the temporary increases in noise and disturbance levels associated with construction at the dam. Aquatic effects would include lake impacts, downstream impacts, and tailwater fishery impacts. If changes were made to pool operation, cultural resources would be affected. A permanent or seasonal pool raise of up to three feet would affect 77 known archaeological sites around the lake shore, only 6 of which have been evaluated and determined not eligible for the National Register of Historic Places. Trailwater fishing losses would be mitigated by improvement of lake management features.

A procedure was developed for estimating the numbers of steelhead Salmo gairdneri and yearling chinook salmon Oncorhynchus tshawytscha smolts passing McNary Dam each day in 1982-1983. The method utilized the fingerling collection and. bypass system contained within the powerhouse. Freeze-branded groups of smolts released upstream from the dam were used to calibrate the efficiency with which migrants were collected over a range of powerhouse discharge levels. Application of collection efficiency calibration curves enabled researchers and fisheries managers to generate daily estimates of smolt passage as a function of the amount of water discharged through the powerhouse and the number of fish collected in the bypass system.

Phase III Report. Volume 1 - Summary AN - 19074823; 8902953 AB - This report represents the culmination of a two-year, three-phase effort to determine the relative impact of DoD activities on the water quality and living resources of the Chesapeake Bay. Phase III applied the tested methodology to the remaining 31 installations identified in Phase I as needing more detailed assessment, and summarizes impacts and program recommendations from an installation, regional, and Bay-wide perspective. With the exception of the Naval Surface Weapons Center at Dahlgren, Harry Diamond Labsa - Blossom Point, and Aberdeen Proving Ground, the military activities appear to play a minor role in the regional or far-field water quality conditions of Chesapeake Bay. Areas that represent ongoing problems at the military installations relate primarily to nonpoint or intermittent pollutant sources that are difficult to control. The discharge of toxics from poorly defined point and nonpoint sources (including abandoned waste disposal sites) is potentially the most important issue related to the preservation of water quality on or near the military installations. Certain toxic constituents (e.g., hydrophobic organic compounds such as pesticides, polynuclear aromatic hydrocarbons, and halogenated hydrocarbons and inorganic compounds such as heavy metals) are of special concern due to the tendency to adsorb to sediments and to accumulate in the estuarine sediment bed, where benthic organisms are exposed over long periods of time.

Most of the area along the river in Henry County is predominately rural with the only city being Napoleon. Knowledge of potential floods and flood hazards is important in land use planning. This report includes a history of flooding along the Maumee River and identifies those areas that are subject to possible future floods. Special emphasis is given to those floods through the use of maps and water surface profiles. While the report does not provide solutions to flood problems, it does furnish a suitable basis for the adoption of land use controls to guide flood plain development and thereby and reduce flood damages which might be embodied in an overall Flood Plain Management program. Other types of studies, such as those of environmental attributes and the current and future land use role of the flood plain as part of its surroundings, would also profit from this information.

Economic analyses to date have overlooked the value of increased mean productivity which result from lock rehabilitation. Productivity increases are measured in terms of decreases in the mean time it takes a tow to transit a lock. The analysis develops a dynamic model for estimating these values. The quantity of public infrastructure capital, i.e., lock capital, cannot be estimated by any of the commonly accepted price or quantity methods due to lack of data. Lock capital is estimated with price data and estimates of asset functions. A recursive system of equations with exogenous demand for lockages at the lock to be rehabilitated is estimated to show the effect of lock capital on transit time. An increase in lock capital is shown to decrease mean values of: (1) the time it takes to service a tow; (2) queue length; and (3) the total transit time required to pass through a lock. The model is solved for Lock and Dam 13 on the Mississippi River. The value of the improved productivity is minimal and relatively insensitive to variations in model assumptions or the estimation of the quantity of capital. Results indicate a need for data on the physical characteristics of public infrastructure capital so its quantity can be estimated. The value of improvements in infrastructure 's mean productivity appear to be insignificant when compared to the value of preventing economic losses which could result from failure or loss of the infrastructure. The importance of an empirical basis for estimating the probability of infrastructure failure is pointed out as is the current lack of data to do this.

AN - 36398305; 1322 AB - PURPOSE: Dredging to deepen the Cape Henry Channel, York Spit Channel, Rappahannock Shoal Channel, Curtis Bay Channel, and the East and West channels of the Northwest Branch of the Patapsco River within the Maryland and Virginia portions of the Baltimore Harbor was proposed in the final environmental impact statement (EIS) of September 1981. The purpose of this second Supplemental Information Report is to present information regarding modifications to dredging and placement of dredged material from the Rappahannock Shoal and York Spit channels in the Virginia portion of the project. The project as discussed in the EIS had 1,000-foot-wide channels in Rappahannock Shoal and York Spit. These channel widths have been reduced to 800 feet therefrom. Stemming from the monitoring program initiated in 1983, potentially better alternate disposal sites have been identified. While baseline monitoring was occurring in the identified (primary) disposal sites, the Army Corps of Engineers extended the monitoring effort to include the alternate disposal sites. Initial screening of candidate sites resulted in a single alternate for the York Spit Channel and a single site for the Rappahannock Shoal Channel. In addition to the environmental monitoring effort, a cultural reconnaissance was performed on the alernate sites. Based on data obtained from these investigations, the alternate sites became the preferred disposal sites and have been identified for use in lieu of the primary sites. In addition, the EIS stated that dredging could not occur in the York Spit or Cape Henry channels between November 15 and March 15, due to the presence of overwintering blue crabs. A study effort was undertaken to document the presence or absence of blue crabs in the channel area. Based on data obtained, the restricted dredging period has been reduced to December 1 through February 28, and has been eliminated completely from the Cape Henry Channel. POSITIVE IMPACTS: The proposed action would result in a reduction of material to be dredged and a corresponding reduction of impacts to the water column and benthos in dredging and disposal areas. The results of the monitoring will provide a basis for assessing impacts and better management techniques for future disposal activities. The choice of alternative disposal sites could be environmentally more suitable for disposal at the same or lower costs. NEGATIVE IMPACTS: Based on the data presented and continued coordination with state and federal resource agencies, no significant adverse environmental impacts are expected to occur from the proposed changes.

AN - 36387086; 1317 AB - PURPOSE: The Shorelands Corporation has applied to the city of Hayward, Almeda County, California for a General Plan Amendment and rezoning to Planned Development, as well as land use permits to construct a horse racing facility, theme park, and other commercial development at the Baumberg Tract in the city of Hayward, adjacent to San Francisco Bay. The overall project would involve approximately 1,256 acres of land, of which 690 acres would be developed for commercial and light industrial uses and roads and 566 acres would be used for public parks and wildlife habitat. The application requests a permit to place 7 million cubic yards of fill material on the project site. The preferred alternative is on a location of the former Baumberg crude salt plant owned and operated by the Leslie Salt Company. The proposed project would develop 687 acres of the 736-acre site and offer 500 acres as wildlife habitat mitigation land. The developed areas would include 300 acres containing a racetrack and ancillary facilities; 203 acres containing an industrial research and development complex; 18 acres for a hotel and visitor uses; 22.5 acres for commercial uses, including restaurants, a bank, and other related uses; 39 acres for an office park; and 20 acres for a recreational vehicle park, 10 acres of which could be converted to industrial research and development uses after the first 10 years of operation. An entertainment park is proposed for 23 acres, which would provide rides, waterways, shows, picnic areas, and an educational and historical component. Within the 736-acre project site, 23 acres are propsed for retention ponds distributed throughout the site; 21.2 acres for ball fields; 31.6 acres for landscaped main track infield; 8.3 acres for landscaped training track infield; and 45.1 acres for new marshland environment, of which 15 acres would be pathways and landscaping. The applicant has proposed a mitigation plan that includes acquisition of 500 acres of existing wetlands consisting of salt water marsh, levees, and salt ponds. This land would be used for wildlife habitat enhancement, marsh restoration, and public access to Bay-related areas. Key to this mitigation plan would be an 80-acre brine shrimp feeding pond, which would continue in the Leslie Salt Company's salt production process. An additional 88 acres would be devoted to wildlife habitat enhancement, which would include 17.2 acres of plover nesting and feeding islands and 69.9 acres of saltwater marsh areas for the encouragement of salt marsh harvest mouse habitat. POSITIVE IMPACTS: Development of the site could provide the impetus for developing surrounding lands and could encourage development of some of the remaining privately owned parcels along the Hayward shoreline. Local businesses would benefit from the infusion of spending by project patrons. Property taxes on project land and improvements would be more than $6.2 million per year. Sales tax revenue generated by the project would be $7.2 million per year. Parimutuel tax revenue would be between $1.5 and $1.8 million annually. The proposed project would result in direct employment of between 12,400 and 16,100 full-time persons at project buildout. Further study of historical sites would contribute to the understanding of the region's history. The preferred alternative would create a wide variety of on-site recreational opportunities. NEGATIVE IMPACTS: Development of the project would permanently commit all or portions of the site to long-term urban uses. The project would cover more than 11 of 17 historical sites identified. The potential exists for damage to structures if the maximum earthquake event should occur on the Hayward fault. There would be a direct, irreversible long-term loss of 697 acres of wetlands and interrelated habitat, as well as direct and indirect impacts to water bird nesting in the project impact area, including the candidate rare and endangered snowy plover and sensitive species such as the great blue heron. Potentially significant traffic impacts could result from the project. Racing activities and construction would result in increased noise levels. Development of the project would require increased development of municipal services.

Preparation date: March 25, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CENTRAL UTAH PROJECT, BONNEVILLE UNIT, MUNICIPAL AND INDUSTRIAL SYSTEM, SUMMIT, WASATCH, UTAH, AND SALT LAKE COUNTIES, UTAH (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1979). AN - 36404926; 1327 AB - PURPOSE: Construction of the Municipal and Industrial (M&I) System of the Bonneville Unit in Salt Lake, Utah, Summit, and Wasatch counties, Utah is proposed. The project would include construction of the Jordanelle Reservoir and associated recreational facilities on the Provo River 38 miles upstream of Utah Lake; completion of the 14-mile Alpine Aqueduct, of which 1 mile is under construction; completion of the remaining 23 miles of the 38-mile Jordan Aqueduct; and modification of 15 upper Provo River reservoirs. Design features of the Jordanelle Dam would include a height of 296 feet, a crest length of 3,110 feet and width of 30 feet, and an outlet works with a multilevel intake structure. Power plant construction will be deferred, awaiting nonfederal participation. The outlet works will be designed to accommodate the convenient addition of a power plant at some future date. The potential to produce 10.4 megawatts will remain. At its total capacity of 320,300 acre-feet, the reservoir would have a surface area of 3,068 acres. The Alpine Aqueduct would consist of 5.0- to 7.5-foot concrete pipe buried at a minimum depth of 3 feet and would transport water treated at the Utah Valley Water Purification Plant. A number of feeder pipelines would connect with existing distribution systems. The Jordan Aqueduct would consist of 4.0- to 6.5-foot concrete pipe and would receive water from the Alpine Aqueduct upstream of the Utah Valley Water Purification Plant for treatment at the Jordan Water Purification Plant. As of January 1986, the Jordan and Alpine aqueducts were approximately 65 percent complete. The purpose of this supplement is to report and evaluate two types of elements: the environmental impacts of proposed modifications to the M&I System plan and impacts or consultations not previously covered. Proposed actions for which analyses or consultations have been conducted include: (1) relocating U.S. Highway 189 along an alignment different from that described in the final environmental impact statement (FEIS), (2) adding a new Wasatch County road; (3) relocating the outlet works of Jordanelle Dam from the right to the left abutment; (4) adjusting the reservoir management boundary and land for project features; (5) modifying the fishery mitigation/recreation plan between the proposed Jordanelle Reservoir and the existing Deer Creek Reservoir by refining Provo River access requirements and eliminating boating and tubing on the river; (6) modifying the wildlife mitigation plan; (7) evaluating impacts to area wetlands; and (8) consultations with the Fish and Wildlife Service regarding the June sucker, a recently listed endangered species. This supplement also provides a brief update of the status of the M&I System. Since filing of the FEIS, some circumstances have changed, some features have been constructed, and progress has been made relative to commitments made in the FEIS. In addition, this supplement provides compliance for the Army Corps of Engineers 404 permit process. POSITIVE IMPACTS: Potential safety hazards would be reduced by the road relocations. Mitigation would be provided for wildlife habitat losses stemming from road location realignments, changes in the reservoir management boundary, and wetland and riparian impacts not previously covered. The project would provide 90,000 acre-feet of water annually for municipal and industrial use in Salt Lake County and northern Utah County. Delivery of 14,100 acre-feet of supplemental irrigation water annually to 22,740 acres of agricultural lands in the Heber and Francis areas would eliminate current late-season water shortages and would reduce excessive early-season applications to these lands, increasing crop production. Stabilization of 12 of the 15 upper Provo River reservoirs would enhance recreational and fishery values in the Wasatch National Forest. Recreational provisions of the reservoir would accommodate 5,160 visitors simultaneously. NEGATIVE IMPACTS: The reservoir project would result in the displacement of 38 residences, 3 businesses, 3 farms, and a small cemetery, and the impoundment would inundate 3,500 acres of wildlife habitat, including 630 acres of scarce, high-value streamside riparian habitat. Closure of the existing Olmsted power plant would result in a net loss of energy production and the elimination of 14 jobs.

AN - 36403711; 1326 AB - PURPOSE: Information is provided in this supplemental information report pertaining to the addition of an upland dredge material disposal site for performing routine maintenance dredging in the vicinity of ranges T and U of the Adams Creek-Core Creek Section of the Atlantic Intracoastal Waterway (AIWW) at the Virginia state line and a section of Gallants Channel, which is part of the Beaufort Harbor, North Carolina project, from its intersection with range T to a point 500 feet northwest of day marker "2" just off Gallant Point. Maintenance dreding would be performed during the fall and winter of any given year and would consist of removal of isolated shoals lying above the plane of 14 feet below mean low water (MLW). Material consisting of predominantly sand, with some shell and mud, would be dredged and disposed of in the upland diked disposal site located on Radio Island, just north of Highway 70 and east of tangent U. Maintenance frequency for these areas would be once every three to five years. The site, which is approximately 25 acres, has been previously used for dredged material disposal. The island is void of vegetation except for the surrounding marsh fringe. Remnant dikes would be reworked to a height of approximately six to eight feet. The effluent outlet pipe is located on the west side of the island. POSITIVE IMPACTS: The maintenance program would allow the continued commercial and recreational use of the waterway. NEGATIVE IMPACTS: The disposal of dredged material would seriously disrupt the underlying aquatic habitat, and dredging operations would destroy the existing benthic environment.

Preparation date: March 10, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SOUTH LAWRENCE TRAFFICWAY FROM KANSAS TURNPIKE TO K-10 HIGHWAY, DOUGLAS COUNTY, KANSAS: PROJECT 23C-2567-01; 23U-1121-01. AN - 36398468; 1310 AB - PURPOSE: Construction of approximately 15 miles of roadway from the vicinity of the Kansas Turnpike (I-70) northwest of Lawrence to a connection with Kansas State Highway (K-10) at Noria Road along the western and southern sides of the city of Lawrence in Douglas County, Kansas is proposed. The recommended action includes widening of existing roads; acquisition of rights-of-way (with a typical width of 250 feet); construction of a four-lane divided roadway with access limited to at-grade intersections with major arterial roadways; construction of grade-separated interchanges at K-10 and I-70; and on- and off-site mitigation of irreversible impacts on construction. The preferred alignment would be divided into four sections. Section 1 would extend from the north project limits to the intersection of County Route 13 and the Clinton Parkway. Section 2 would extend from the County Route 13/Clinton Parkway intersection to a divergence of alignments at a point one mile south and three-quarters of a mile west of the existing Clinton Parkway/Kasold Lane intersection. Section 3 would extend from the end of Section 2 to a divergence of alignments at a point one-quarter mile west and one-quarter mile north of the intersection of Noria Road and 31st Street extended. Section 4 would extend from the end of Section 3 to interchange sites along K-10 in the vicinity of Noria Road. The total cost for the ultimate four-lane trafficway is estimated at $37.7 million. POSITIVE IMPACTS: The proposed action is necessary to relieve congestion on existing 23rd and Iowa streets. The proposed roadway would divert through and local traffic from these two streets and Clinton Parkway, thereby achieving an improved level of traffic on the local street network. Traffic safety benefits would be experienced due to reduced congestion. Contractors within the Lawrence area would receive a portion of the cost of construction. Experience with other highway construction suggests that approximately 25 percent of the construction cost goes to salaries, and most of this money would be injected into the area economy. Money for expressway maintenance would be injected into the local economy for the life of the project. Douglas County would have a new circumferential transportation system in place that could make the county an attractive location for private investments. NEGATIVE IMPACTS: Adverse socioeconomic impacts include taking of prime agricultural land and displacement of five residences. Construction would cause localized disruptions in traffic flow through detours and construction activities and temporary increases in noise and air pollution. Impacts on the natural environment include the taking of ecologically sensitive areas, such as state designated critical habitat and federally designated, but as yet unprotected, species of plants.

AN - 36401928; 1280 AB - PURPOSE: A plan of improvement is proposed to realign, widen, extend, and deepen the existing channel in Port Jersey to 41 feet mean low water (MLW) within the Upper New York Bay at Bayonne and Jersey City, New Jersey. Port Jersey access channel is presently at an average depth of 35 feet MLW. The proposed plan recommends dredging to the optimal depth of 41 feet; 2 feet of overdepth dredging would also be included within the channel. The interior channel would be widened to between 440 feet and 570 feet to provide access to all potential users (Global Terminal & Container Services (GT&CS), Military Ocean Terminal (MOT), and the Port Authority of New York and New Jersey). The northern limit of the proposed channel would be 110 feet from and parallel to the GT&CS bulkhead, providing a 110 foot berthing area. The southern limit would be 200 feet from the MOT bulkhead. At the eastern end of the inner channel, the channel bends 12.5 degrees; at the apex of the bend, the width of the channel is 400 feet. The outer channel is 300 feet wide from the main bend to a point 1,000 feet from the end of the channel, where it begins to widen to a width of 1,140 feet perpendicular to the east end of the channel. The turning basin at the west end of Port Jersey Channel would be 1,200 feet in diameter. Ocean disposal of dredged materials is also proposed. Results from bioassay tests indicate no problems with the disposal of dredged material from the channel to dump sites at sea. It is estimated that approximately 1.6 million cubic yards would be dredged from the proposed 43-foot deep (41 feet, plus 2 feet overdepth) channel. Total first costs are estimated at $11.7 million for channel construction and $2.4 million for berthing areas and bulkheads, with a benefit-to-cost ratio of 8.6. POSITIVE IMPACTS: By deepening the Port Jersey Channel, the ocean transportation costs associated with the movement of imports to and exports from the GT&CS marine terminal would be reduced. Waiting times required for tides, to ensure adequate clearance of vessels using the channel, would be reduced. These waiting times have an effect on costs, which deepening the channel would reduce. NEGATIVE IMPACTS: Benthic organisms would be harmed by turbidity, sedimentation, and bottom removal during dredging operations. Possible oil discharges from any vessels would be harmful to all types of marine life, particularly in the intertidal zone. Dredging activities, as well as ocean disposal, are expected to result in short-term effects on water quality.

Preparation date: March 4, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - APPLEWHITE DAM AND RESERVOIR AND LEON CREEK DIVERSION DAM AND LAKE, SAN ANTONIO RIVER BASIN, BEXAR COUNTY, TEXAS. AN - 36400312; 1283 AB - PURPOSE: A permit application has been filed by the San Antonio City Water Board for construction of the Applewhite Dam and Reservoir, which would be located on river mile 11.6 of the Medina River in Bexar County, Texas. Construction of a diversion dam on Leon Creek and a diversion canal connecting the Leon Creek impoundment and Applewhite Reservoir is also proposed. The project includes an earth-filled dam approximately 12,100 feet long across the Medina River, 2.4 miles upstream of its confluence with Leon Creek. The embankment would create an impoundment of 2,500 surface acres. At the expected maximum high water level elevation of 547.3 feet mean sea level (msl), the reservoir would inundate 4,804 acres. The diversion dam on Leon Creek would divert flood flows from that creek into Applewhite Reservoir. Up to 544 acre-feet of water would be impounded within Leon Creek at elevation 536 msl. A 6,300 foot long diversion canal would connect the Leon Creek impoundment with the reservoir. Other features of the project include a pump station located approximately 200 feet from the upstream side of the dam on the north shore of the reservoir, a 70 million gallons per day (mgd) water treatment plant covering 60 acres, and a 5,400 foot raw water pipeline connecting the two. POSITIVE IMPACTS: The proposal would provide approximately 53,000 acre-feet of water per year for municipal and industrial purposes. Since impoundment of this water would result in increased springflow from the Edwards aquifer, the regional net water gain would be approximately 30,000 acre-feet per year. The reservoir would provide 2,500 acres of lake surface and 45,251 acre-feet of aquatic habitat at the conservation pool level of 536 feet msl. By reducing demand on the Edwards aquifer, the integrity of springs such as San Marcos and Comal Springs and their dependent threatened and endangered species would be enhanced. Future expansion of San Antonio's surface water supply system to include additional reservoirs could be accommodated by doubling the capacity of the treatment plant to 140 mgd. The initial site purchase would be sufficient for the ultimate development of the plant. NEGATIVE IMPACTS: Relocation of approximately 95 residences, between 3 and 5 cemeteries, and several transportation arteries and utilities would be required. The proposed project would destroy 18 miles of riparian habitat and inundate some 6,500 acres of prime farmland. Approximately eight acres of wetland would be flooded.

Preparation date: March 4, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED NONCONNAH PARKWAY FROM I-240 TO STATE ROUTE 57, SHELBY COUNTY, TENNESSEE. AN - 36397939; 1271 AB - PURPOSE: Construction of a new road in the Nonconnah Parkway corridor from I-240 east of Mt. Moriah Road to State Route (SR) 57 in Colliersville, Shelby County, Tennessee is proposed. The Nonconnah Parkway Project would begin with improvements along existing I-240, beginning from the west at the Perkins interchange, proceed eastward through the Mt. Moriah and proposed Nonconnah Parkway interchanges to the Poplar interchange. The project would proceed approximately 10.2 miles eastward to its terminus just east of the junction with SR 57. The preferred alignment stays just to the north of the proposed revised floodway beginning at I-240 and proceeds in an easterly direction to Kirby Parkway. East of Kirby Parkway, it enters the floodway and crosses Nonconnah Creek and stays out of the floodway on the south side of the creek, then shifts back to the north side of the creek just east of Riverdale, and primarily follows existing Winchester Road before merging with SR 57 and terminating. The proposed parkway would be an access-controlled, grade-separated facility with a minimum 200 foot right-of-way. Interchanges would be constructed at I-240, Ridgeway, Kirby Parkway, Riverdale, Germantown-Winchester, Hacks Cross Road, Forest Hill-Irene, Houston Levee, and SR 57 (Poplar). Structures other than those at the interchanges include two bridges over I-240, two bridges over Nonconnah Creek, one bridge over Knight Arnold Road, and one bridge over Bailey Station. Extensive bridging would also be required for the parkway east of Kirby Parkway through the floodway, approximately 2,600 feet. Frontage roads would be built where required to provide access to landlocked parcels. Construction would consist of six 12-foot traffic lanes with a 22-foot median and two 12-foot (10-foot paved) outside shoulders. An additional 12-foot auxiliary lane would be added for both east- and westbound traffic between the I-240 and Ridgeway interchanges to provide more needed capacity in this congested area. Auxiliary lanes would also be added for westbound traffic between the Riverdale and Germantown-Winchester interchanges and between and within the Germantown-Winchester and Hacks Cross Road interchanges to develop two-lane entrances and exits, to better facilitate merging and diverging traffic, and to increase the level of service along the mainline. POSITIVE IMPACTS: The primary beneficial impacts of the proposed project include improved local and regional accessibility and traffic service, reduction of traffic congestion on existing highways and streets, improved safety and operating conditions in the transportation corridor, and enhancement of future planned growth and development as proposed by local land use and major thoroughfare plans. Driving times, accident rates, road user costs, and accident costs would be substantially reduced. Rail lines serving the area are expected to expand service as industrial development increases. NEGATIVE IMPACTS: The primary adverse impacts of the preferred alternative include displacement of 18 residences and businesses, a reduction of wildlife habitat, possible impacts on archaeological and historic sites, introduction of air and noise pollution in new areas, visual impacts on isolated and residential areas, the loss or substantial modification of wetlands acreage, and temporary construction impacts such as fugitive dust, equipment noise, inconvenience to motorists, and temporary siltation of streams. The project would encroach the Nonconnah Creek floodplain.

Concentrations of lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), barium (Ba), and calcium (Ca) were measured in two skinless, boneless samples of axial muscle from individual fish prepared in a clean room. One sample (normally processed) was removed from each fish with a knife in a manner typically used by investigators to process fish for elemental analysis and presumably representative of methods employed by anglers when preparing fish for home consumption. A second sample (clean-processed) was then prepared from each normally-processed sample by cutting away all surface material with acid-cleaned instruments under ultraclean conditions. The samples were analyzed by atomic absorption spectrophotometry. Only Pb regularly exceeded current guidelines for elemental contaminants in food. Concentrations were high in black redhorse from contaminated sites, regardless of preparation method; for the other fishes, Pb levels depended upon preparation technique. Except for Mn and Ca, concentrations of all elements measured were significantly lower in clean than in normally precessed tissue samples. Concentrations of Pb, Ca, Mn and Ba in individual fish were closely correlated regardless of sample size, while correlations between Zn, Fe, and Cd occurred only in normally-processed samples (suggesting that these correlations resulted from high concentrations on the surfaces of some samples). Reported concentrations of certain elements should be regarded only as estimates and regardless of the care exercised during the collection, preparation, and analysis of samples, results should be interpreted with the awareness that contamination from external sources may have occurred.

AN - 36394928; 1246 AB - PURPOSE: Construction of three new barracks projects is proposed within the Main Post area of the Presidio of San Francisco, California. Facilities would be provided for housing approximately 600 bachelor enlisted personnel and for dining, supply, and operations facilities required to support these soldiers. The 098 barracks project would contain 10 barracks modules for 313 persons, a dining facility, and two administrative buildings. In a central location, between the barracks clusters and the dining facility, a level outdoor area would be constructed for troop formation and lawn areas for recreation. On the east side of the proposed dining facility, an outdoor dining area would be built. The remainder of the site would be landscaped with lawn, shrub, and tree plantings in the formal foundation pattern used in the surrounding Letterman Army Medical Complex (LAMC) and Main Parade Ground areas. Paved pedestrian walks would be constructed between the structures and other barracks on the site. These walks would also serve as service and emergency vehicle access routes. Construction of the 098 barracks project would begin in late 1987. The 119 project would consist of two three-story barracks buildings (8 modules) totalling 62,540 square feet, for 167 persons; these would be medical staff who would dine at the LAMC. The 119 barracks would be located in the middle of the 15.5-acre project site, immediately north of the proposed number 98 barracks complex. This area is open, and no building demolition would be required. The area between the proposed barracks and Gorgas Avenue would be replanned to provide 100 parking spaces, with tree planting islands and planted buffer strips separating the parking area from the streets and buildings. In the central area between the two proposed barracks would be a paved plaza for troop formation and recreation space. The plaza would connect to adjoining streets, adjacent barracks, and parking areas by pedestrian walkways, which would function as service and emergency vehicle access to the buildings. The remainder of the site would be planted with lawn, shrubs, and trees in the foundation planting pattern used in adjacent areas. Construction of the 119 barracks project is proposed to begin in late 1987. The 124 barracks would be a three-story building of approximately 41,800 square feet. This project is still in the design stage; although the site has been selected, the details of the building have yet to be determined. The proposed location is on the northeast corner of the 15.5-acre site, adjacent to Gorgas Avenue. It would require demolition of two existing temporary nonhistoric structures. Parking for approximately 80 cars would be accommodated within the overall site. The proposed barracks would house approximately 120 bachelor enlisted garrison personnel, the majority of whom are currently housed in the Fort Scott barracks. The contract for the project 124 barracks is programmed to be awarded for construction in fiscal year 1989. POSITIVE IMPACTS: The new barracks would replace present older barracks facilities that are inadequate, contain life-safety hazards, do not meet current seismic standards, and are difficult and expensive to operate and maintain, with safe, modern housing for enlisted personnel that would appreciably improve living conditions and troop morale. Availability of good housing for medical personnel would support the treatment, research, and training missions inherent in the LAMC facilities, with beneficial effects for users of these facilities. The proposed site would allow all enlisted barracks to be conveniently located, thereby reducing transportation between residences and work, support facilities, and Army community facilities, especially for those enlisted personnel now living off the base. Construction would provide opportunities for employment and procurement in the primary building and supply trades and industries, with economic and social benefits in the immediate city area. NEGATIVE IMPACTS: Much of the rough grass and lawn areas would be converted to buildings, parking areas, and hard surface walkways, especially for the 119 project. Increased short-term noise would occur during demolition and construction operations. The use of the 15.5-acre site would require removal of Thompson Hall, a historic structure, and a small area of young trees at the edge of Thompson Hall. The loss of Thompson Hall as a guest house for LAMC patients and families would require provisions for a new guest home.

AN - 36403434; 1268 AB - PURPOSE: Widening and new construction of Route 28 in Montgomery County, Maryland, beginning at Jones Lane and extending easterly to Interstate 270 (I-270), a distance of 6.25 miles, are proposed. The project would also include improvements to Maryland Route 124 from approximately 1,000 feet south of Route 28 to 4,000 feet north of Route 28, tying into the existing improved section constructed by Montgomery County. The project alternatives under consideration include two build alternatives in Segment 1 (alternates 2 and 3), which runs from Jones Lane to Key West Avenue. Alternate 1-2 proposes widening and reconstruction of Route 28 to a curbed section minor arterial highway. The improvements would be constructed within a 120-foot right-of-way established by Montgomery County through development setbacks over the years. Beginning at approximately Ancient Oak Drive, the existing roadway would be widened to provide a six-lane roadway with a 20-foot median to provide storage for left-turning vehicles. For Segment 1, Alternate 2 would follow the existing alignment through Segment 1 to the intersection of Route 28 and Key West Avenue. Alternate 3 proposes widening and reconstruction of Route 28 to a curbed section minor urban arterial highway. The existing roadway would be widened to provide a six-lane roadway with a 30-foot median and would be contained within a proposed 142-foot right-of-way. The alignment of this alternate is the same as that for Alternate 2. For Segment 2, the preferred alternative begins at Station 285+00, approximately 600 feet west of the intersection of Key West Avenue and Route 28. This alternative proposes that Key West Avenue be designated as Route 28 for through traffic, leaving existing Route 28 for local traffic. Relocated Route 28 via Key West Avenue would provide a six-lane partial controlled-access roadway with a 30-foot median contained within a 150-foot right-of-way. Two lanes of Key West Avenue have been constructed from the intersection of Route 28 to Shady Grove Road. Montgomery County is constructing Key West Avenue from Shady Grove Road to Gude Drive extended, along the Master Plan Alignment for Route 28. From Gude Drive, the proposed alignment continues in a southeasterly direction to tie into existing Route 28, 800 feet west of Research Boulevard. It would continue to the limit of the project at approximately station 434+00 to tie into the proposed improvements of the interchange of I-270 and Route 28. POSITIVE IMPACTS: The proposed improvement would relieve congestion on the existing facility and improve traffic operations through the study area, providing improved access to an area planned for residential, institutional, and high-tech development, based on established zoning. NEGATIVE IMPACTS: The number of residential relocations varies from 2 to 20. Muddy Branch Park and proposed high school facilities would be impacted by build alternates 2 and 3. Alternate 2 would require the acquisition of 2.8 acres from the Tschiffley-Kent historical site and 1.6 acres from the Belward Farm historical site. The build alternates in Segment 1 would cross Muddy Branch and its 100-year floodplain, and the preferred alternate in Segment 2 would cross Watts Branch and its 100-year floodplain. All of the alternates would impact some wetlands. The build alternatives in Segment 1 would result in two sites experiencing noise levels in excess of noise abatement criteria.

AN - 36386721; 1263 AB - PURPOSE: Extension of Eagle River Loop (Route No. U-551) approximately 2.5 miles to the Glenn Highway/Hiland Drive Interchange is proposed. The project is located in the municipality of Anchorage, Alaska, near the community of Eagle River. A new four-lane urban arterial would be constructed from the Hiland Drive Interchange to a bridge crossing at the south end of Eagle River Loop Road, and Eagle River Loop Road would be reconstructed to a five-lane urban arterial from the bridge crossing to Eagle River Road. This would be a partial-control-of-access facility, meaning that access to the facility would be provided at only preselected intersections or interchange locations. The preferred alignment departs Hiland Drive one-quarter of a mile east of the interchange. It closely follows a four-wheel drive road for approximately two miles before crossing the river 100 feet from the south end of Eagle River Loop Road. It then connects to Eagle River Loop Road adjacent to Mills Bay Drive. This alignment would require a 585-foot bridge. The estimated cost of the preferred alternative is $55 million. POSITIVE IMPACTS: The proposed action would provide an additional access to the Glen Highway for Eagle River Valley residents, which would improve traffic flow to, from, and within Eagle River. There would be better distribution of traffic in the Eagle River area. A temporary positive impact associated with all alternatives would be the large percentage of construction funds remaining in the Anchorage area as wages or for purchase of goods and services. NEGATIVE IMPACTS: Negative impacts associated with the proposed action include business (2) and residential (21) relocations, wetlands fill (4.0 acres), floodplains involvement, increased noise, and construction activity.

AN - 36404444; 1275 AB - PURPOSE: Construction of flood control facilities on Coyote Creek in the southern San Francisco Bay region, California is proposed. The project would be constructed in the cities of San Jose and Milpitas, extending along Coyote Creek for a distance of approximately 6.5 miles. The project area is divided into three reaches: Reach 1 begins at the Southern Pacific Transportation Company railroad bridge near Drawbridge and ends at the Milpitas Pumping Station; Reach 2 extends from the Milpitas Pumping Station to Highway 237; and Reach 3 starts at Highway 237 and terminates at Montague Expressway. A bypass channel is planned for Reach 1, which would require limited excavation near its upstream terminus. The channel would follow the existing Coyote Slough around the southern side of Newby Island. Earthen levees would be constructed on both sides of the bypass channel, and a retaining wall would be installed close to the end of the reach. An excavated, earthen overflow channel would be constructed in Reach 2 and Reach 3. The overflow channel would be situated on the floodplain adjacent to the existing Coyote Creek channel and would cross the stream in several locations. These crossover locations would be lined with riprap. Concrete- and rock-lined sections would be necessary under the Highway 237 and Montague Expressway bridges, respectively. Earthen levees and a relatively short section of floodwall are proposed to help contain flood-flows in the overflow channel. A mitigation program developed to compensate for adverse environmental effects would include establishment of wetland and upland habitat, planting of 42 acres with riparian species, and protection and long-term management of endangered species habitat. Project costs are estimated at $32 million. POSITIVE IMPACTS: The proposed project would provide communities with protection from serious flooding. Implementation would result in far less maintenance-related clearing of vegetation in the Coyote Creek streambed. Over the long term, this would permit natural succession to occur without interruption, thereby benefitting the quality of instream riparian habitat. NEGATIVE IMPACTS: The following impacts would be partially offset through a mitigation program. Approximately 16.5 acres of a salt evaporation pond, used by numerous bird species for foraging and resting, would be eliminated. Approximately 1,850 riparian trees (nearly 15 percent of existing trees along Coyote Creek) would be removed at various locations, resulting in 18 permanent breaks in the continuity of the riparian corridor. These breaks would reduce wildlife diversity by eliminating species unable to maintain their populations due to migration barriers. In addition, small animals, reptiles, amphibians, and nesting birds would be lost due to construction operations. The visual quality of the creek would be adversely impacted. Implementation of the preferred alternative would require a commitment of 345 acres for rights-of-way. At least one occupied house, a packing-shed facility, and an undetermined number of structures, some historically significant, would be relocated.

BR-014-1(28). AN - 36380505; 1266 AB - PURPOSE: Rehabilitation or replacement of the existing "Million Dollar Bridge," carrying State Route 77 over the Fore River between Portland and South Portland, Cumberland County, Maine is proposed. The project limits extend from Broadway in South Portland to York Street in Portland, a distance of approximately 1.2 miles. The existing four-lane movable bridge is structurally deficient and functionally obsolete. Seven alternatives are under active consideration: (1) No Action; (2) Rehabilitate the Existing Facility; (3) Construct a Low-Level Movable Bridge on Alignment DS/B; (4) Construct a Mid-level Movable Bridge on Alignment DS/B; (5) Construct a Low-level Movable Bridge on Alignment DS/W; (6) Construct a Mid-level Movable Bridge on Alignment DS/W; and (7) Construct a Low-level Movable Bridge on Alignment DS/WO. The DS/B, DS/W, and the DS/WO alternatives would provide four-lane divided roadways (12-foot lanes) with combined shoulder/bikeways on the outside and a four-foot inside shoulder. A two-foot concrete median barrier would separate opposing traffic. A six-foot separated and barrier-protected sidewalk would be located on the upstream side of the bridge. Approach spans would be of steel or concrete construction. The main span would be a double-leaf bascule bridge, providing a minimum of 220 feet of horizontal clearance and unlimited vertical clearance for shipping. The movable span design would accommodate channel widening and deepening by others to a maximum of 45 feet in depth and 220 feet in width. The existing northerly channel line would be retained, with all widening to occur to the south. The Rehabilitation Alternative retains the same vertical and horizontal geometry as the existing bridge, but replaces the near 90-degree turn on the Portland Approach with a flatter curve. A new bascule span providing 220 feet of horizontal clearance is included. The existing superstructure would be removed, the pier caps would be widened, and a new deck would be constructed on the modified substructure. The life-cycle costs are estimated at $33.7 million to $94.7 million, with benefit/cost ratios of from 3.26 to 3.73, depending on the alternative chosen. POSITIVE IMPACTS: Traffic circulation would be improved in South Portland by the DS/B or DS/W alternatives. Accidents would be reduced. The mid-level bridges would reduce delays due to bridge openings. Substantial savings in shipping costs would occur to harbor users, and navigation hazards would be reduced. The DS/B and DS/W alternatives would contribute to lower noise levels in South Portland. NEGATIVE IMPACTS: All build alternatives would displace at least five commercial activities in Portland and from one to three, depending on the alternative chosen, in South Portland. All of the build alternatives would impact wetlands to some degree. Properties that may be subject to Section 4(f) procedures include Gateway Park and Legere Park in South Portland. Construction activities would impact visual resources, and erosion, turbidity, and resuspension of heavy metals from sediments.

Preparation date: February 9, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CROSS RANGE EXPRESSWAY: US TRUNK HIGHWAY 169 FROM US TRUNK HIGHWAY 2 IN GRAND RAPIDS TO MINNESOTA TRUNK HIGHWAY 65 IN PENGILLY, ITASCA COUNTY, MINNESOTA. AN - 36401500; 1269 AB - PURPOSE: Improvement of an 18-mile segment of Trunk Highway (TH) 169 from a basic two-lane highway to a four-lane divided expressway in Itasca County, Minnesota is proposed. The limits of the proposed project extend from the junction of TH 2 in Grand Rapids to the junction of TH 65 in Pengilly. Construction activities would consist of grading, surfacing, replacing highway and railroad bridges, and reconstructing several major intersections. Other considerations in the design process include drainage, existing utilities, bicycle and pedestrian facilities, and application of traffic control devices. It has been determined that additional rights-of-way would have to be acquired to accommodate the improved roadway, regardless of the alternative alignment decision. The project has been divided into five segments; for each segment there are from 1 to 3 different alignment alternatives, for a total of 12 alternative alignments. The total estimated cost of the project is between $38 million and $40 million, and construction is anticipated to begin in 1989. POSITIVE IMPACTS: This project would result in the completion of the Cross Range Expressway between Grand Rapids and Virginia and would result in a continuous 60 mile four-lane divided, limited-access roadway connecting the principal cities along the Iron Range. The major beneficial impact would be the improvement of traffic flow and safety. Short- and long-term economic impacts would accrue to the study area as a result of improved access to business and industrial sites. Community development would be assisted by long-term economic gains. The proposed drainage system for the project includes the creation of up to 20 new ponding areas and wetlands, which would minimize the impacts associated with increases in runoff, provide replacement of wet areas lost, and provide new wildlife habitat. The bicycle rating would improve from unsatisfactory to good, and the project would present opportunities for the development of roadside parks and rest areas. NEGATIVE IMPACTS: Between 14 and 47 residences and up to 5 businesses would have to be relocated, depending on the combination of alternatives chosen. Alternative 1B would result in the loss of approximately 140 acre-feet of storage in the Prairie River floodplain. Construction would result in violation of State Nighttime Noise Standards at up to 41 residences. Major wildlife impacts would be associated with Alternative 4A, more specifically, the possible encroachment into the north end of Mud Lake, which would likely result in adverse impacts to double-crested cormorants and great blue herons.

Preparation date: February 6, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DEVELOPMENT OF THE PROPOSED EAST FORK SKI AREA AND FOUR SEASON RESORT ON THE PAGOSA DISTRICT, SAN JUAN NATIONAL FOREST, MINERAL COUNTY, COLORADO. AN - 36401433; 1257 AB - PURPOSE: A Special Use Permit has been applied for by the East Fork Joint Venture to develop a downhill ski area on National Forest System land, located approximately 17 miles northeast of Pagosa Spring, Colorado in the valley of the East Fork of the San Juan River. The ski area, which would be part of a proposed four season resort, would be capable of accommodating 13,500 skiers at one time. Four alternatives were considered. Approximately 2,780 acres of private land and 7,070 acres of adjacent Forest System Land are involved. Development would include approximately 1,374 acres of groomed ski trails served by 18 ski lifts and a gondola. The proposed ski area would offer approximately 3,400 vertical feet of skiing. A major cross-country ski component is also proposed. In addition to the obvious cross-country opportunity in the valley, many miles of trails are possible in the western portion of the proposed permit area, known as the Sand Creek Drainage, and in the High Quartz Meadow on the eastern edge of the area. Nordic skiers would be able to take a lift to the upper portions of the area and ski the ridges or descend gradually to Sand Creek or Quartz Meadows and return to the base area through the East Fork Valley. The mountain development is proposed to be constructed in phases. Each phase would attempt to keep the mountain in balance with respect to the mix of terrain suited to each skier ability. Phase I would include development of Lifts 1, 2, 10, 12, 8B, 9, and the gondola to the top of Quartz Ridge, which would give East Fork the full 3,400 vertical feet of skiing, 374 acres of trails, and a capacity of 4,500 skiers at one time. One maintenance building and the Clamshell Restaurant would also be included in this phase. In addition, the existing access road from Highway 160 to and through the site, which now is a single-lane gravel road, would be improved to a two- and three-lane asphalt roadway. A key component of the base area plan is the proposed river restoration. Based on detailed natural hydrologic principles, the existing broad, braided river would be confined to a natural meandering pattern. The resulting configuration would give the river a natural appearance as well as improved sedimentation, flood control, wetlands, and fisheries habitat. POSITIVE IMPACTS: Improved access could aid exploration. Increased water yields would result from mountain development. The major impact to water resources would be the proposed river renovation that would reduce sediment significantly, generally improve water quality, and protect high-quality wetlands even after the impacts of development; the quality of fishing would positively benefit. The proposed project would generate economic activity during the winter when the area is least active, which would increase the public revenue base. NEGATIVE IMPACTS: Nine archaeological sites, as well as a road corridor, would be affected and would require mitigation. Development would impact as many as 2,270 acres of vegetation on both public and private land. Significant impacts could result from base area development on private land infringing upon calving and fawning areas, migration routes, critical range, and hunting areas for threatened and endangered species.

Preparation date: February 6, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NEWARK BAY/KILL VAN KULL NAVIGATION PROJECT, NEW YORK AND NEW JERSEY (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JULY 1981). AN - 36388174; 1281 AB - PURPOSE: Widening and deepening of the federal navigation channels in Kill Van Kull and Newark Bay, New Jersey and New York are proposed. Deepening would be from 35 feet to 44 feet Mean Low Water (MLW) in sediment and 47 MLW in rock. Channels would be widened at selected sites to permit safer turns and to eliminate sharp bends. Pipeline and utility cables on or under the existing bottom would be lowered or removed, and berthing and local access areas at port facilities would be dredged to commensurate channel depths. Approximately 25 million cubic yards of dredged materials would be disposed of at the mud dump in the New York Bight. The results of a detailed study to evaluate disposal methods indicate the New York Bight to be the only viable option. This final supplemental environmental impact statement (EIS) indicates that detailed fishery and benthic sampling occurred during 1984 and 1985. The results show that the area is an equivalent habitat to surrounding portions of the Hudson estuary regarding fish populations. The benthic community appears more restricted, and the project area also appears very homogeneous with regard to shallow and deeper areas. This supplement also provides additional information on the project area's aquatic population and sediment quality, details related hydraulic impacts, and updates the disposal alternative discussed in the final EIS. It also contains an evaluation for potential barge overflow during the dredging operation. Estimated cost of the project is $166.3 million, and the benefit-cost ratio is estimated at 9.0. POSITIVE IMPACTS: Improvements in navigation and reduction in marine traffic would reduce loss of life, oil spills, and costs associated with marine accidents. Increased navigational safety and the reduced likelihood of oil spills also would benefit recreational resources. Deeper channels would permit ships to arrive at the docks fully loaded, which would reduce transportation costs and help to maintain the commercial viability of the port. Maintenance of oceanborne commerce also would be beneficial to local rail service and the interstate highway system. Removal of polluted bottom material would be a long-term direct benefit to the project area. NEGATIVE IMPACTS: Enlarging the channel would result in a moderate decrease in the flushing capability of the bay, an increase in the rate of shoaling, and an upstream shift in the location of major shoaling areas. Maximum and average current velocities probably would be reduced by the channel enlargements. If the changes result in a significant upstream predominance of bottom flow, sediments would be carried into and trapped in the enlarged channels. Some shallow water areas would be lost, and deepening could result in a change in the benthic inhabitants. Bottom vegetation would decline because of decreased light penetration. Disposal of dredged material would further degrade the ecosystem in the New York Bight.

Preparation date: February 5, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STACY RESERVOIR, DAM, AND PUMP STATION, CONCHO, COLEMAN, AND RUNNELS COUNTIES, TEXAS. AN - 36386763; 1242 AB - PURPOSE: A permit application by the Colorado River Municipal Water District (CRMWD) is being considered for the proposed Stacy Dam, Reservoir, and Pump Station in the Upper Colorado River Basin of Texas. The project area is located within Coleman, Concho, and Runnels counties in Texas. A dam would be created at river mile 615.1. The area to be inundated at elevation 1,551.5 feet above mean sea level (19,200 acres) consists of farm- and rangelands (including 5,000 acres of prime farmland) and encompasses the hamlet of Leaday, Texas. The reservoir is designed to allocate 103,000-acre-feet of water per annum (WPA) for municipal and domestic purposes and 10,000-acre-feet of WPA for industrial purposes, with an 'adopted yield' of 90,700 acre-feet. Corps of Engineers alternatives are to issue a permit, issue the permit with conditions, or deny the permit. The Fish and Wildlife Service has recommended specific mitigation measures to compensate for lost habitat, suggesting acquisition of 197 acres of in-kind habitat and an additional 8,226 acres of rangeland habitat. Mitigation measures are also suggested for archaeological sites, directing research, publication, and protection of excavated materials. POSITIVE IMPACTS: Issuance of the required permits would allow the CRMWD to develop the available water resources at the Stacy Reservoir project site and thereby supply municipal and industrial water to customers in the water district's market area. The influx of construction personnel would have a mixed beneficial and adverse socioeconomic impact on the study area. NEGATIVE IMPACTS: Controversial issues include impact on a proposed threatened species, loss of current use of lands that would be inundated, terrestrial habitat losses, cultural resource losses, and disruption of community cohesion of project area residents. Cultural resources in the project area would require protection or salvaging. One person in Leaday would be displaced from his home. Approximately 5,000 acres of designated prime farmlands would be inundated. Stream segments with potential for designation as wild or scenic streams also would be inundated. Downstream riverine habitat would be variously impacted, depending on timing and volume of water releases from the dam. Based on available information, the project could jeopardize the continued existence of the Concho watersnake and adversely modify its proposed critical habitat.

Preparation date: February 4, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ARCO COAL OIL POINT PROJECT, SANTA BARBARA CHANNEL, CALIFORNIA. AN - 36394347; 1205 AB - PURPOSE: Development of oil and gas leases PRC 208, 308, 309, 3120, and 3242 in state waters offshore of the Goleta area in Santa Barbara County, California by Atlantic Richfield Company and its subsidiaries, ARCO Oil and Gas Company (ARCO) and Four Corners Pipeline Company, is proposed. The project would consist of several major components required to produce oil and gas from the leases. They include (1) three offshore platform complexes for drilling and production of oil and gas; (2) an oil processing facility to remove the water and other impurities occurring with the crude oil, which would be built on the site of the existing Ellwood oil and gas treating facility; (3) a new gas treatment facility to remove water, hydrogen sulfide, and other impurities found in the produced natural gas, which would be constructed at Las Flores Canyon; (4) onshore and offshore pipelines for transport of oil and gas; and (5) storage tanks for processed crude oil, which would be constructed at Dos Pueblos South. Although the five leases are located adjacent to one another and are under the control of the same operator, each lease was issued separately and has its own lease terms and royalty formula. POSITIVE IMPACTS: Production from these five leases would generate royalties to the state of California. Also, the county of Santa Barbara would receive one percent of the royalty paid to the state. The reserves proposed to be developed by this project constitute an economically significant domestic fossil fuel resource within the continental United States. It is estimated that between 200 million and 300 million barrels of oil and 200 million to 500 billion standard cubic feet of natural gas can be recovered from the leases. Additional beneficial impacts would occur in the area of recreation and tourism, with provision of coastal trails and coastal access and creation of artificial marine habitats. NEGATIVE IMPACTS: Adverse impacts include but are not limited to: (1) facility damage due to seismic shaking; (2) increased sediment loads in streams from erosion; (3) damage to or disturbance of marine habitat due to construction of offshore platforms and pipelines; (4) loss of woodlands, riparian areas, and possibly endangered species due to facility and pipeline construction; (5) disturbance to Native American cultural sites during construction; (6) conversion of agricultural lands to industrial use; (7) visual degradation; (8) disruption of commercial and sport fishing; and (9) disruption of research activities.

Some of these models can even make operational decisions regarding proper gate regulations to obtain a desirable water quality condition at a dam site for a given set of flow conditions. HEC-5Q, Simulation of Flood Control and Conservation Systems (Including Water Quality Analysis) computer, model has the unique capabilities to accept user-specified water quantity and quality needs system-wide and to decide how to regulate the network of reservoirs. The decision criteria are programmed to consider flood control, hydropower, instream flow (municipal, industrial, irrigation, water supply, fish habitat) and water quality requirements. The model uses a linear programming algorithm to evaluate the "best" operation of multilevel intakes at each reservoir in the system. The user may select to operate the system for a balanced reservoir pool operation and its associated water quality or to allow for a modified flow distribution between reservoirs to improve the water quality operation. HEC-5Q has been applied to the 10,000 square mile drainage area of the Sacramento River System. The Sacramento system includes two tandem reservoirs, three parallel reservoirs and 400 miles of stream channel network. An application of the Kanawha River System in West Virginia includes using the model for five-day real-time forecasting of reservoir operations every morning during the low-flow season. The Monongahela River System application in West Virginia includes using the model to determine the best reservoir operation for a project nearing completion. JF - Technical Papers.

AN - 36405657; 1241 AB - PURPOSE: Implementation of a plan to address identified flood and water supply problems in the West Branch of Brandywine Creek Watershed, located in Chester and Lancaster counties, Pennsylvania, is proposed. The watershed encompasses approximately 135 square miles. The proposed plan includes the installation of a single-purpose dam (PA-428) for flood control on Sucker Run and two multipurpose dams (PA-430 and PA-436F) for flood control and water supply on Rock Run and Birch Run. It would also include continuation of the ongoing land treatment program. The three sites in the proposed project would control approximately 22 percent of the total drainage area above the Coatesville damage center and 19 percent of the drainage above the Modena damage center. Together, the dams would reduce average annual damages by 67 percent. The estimated installation cost is approximately $9.6 million. Total average annual equivalent water supply and flood reduction benefits of $593,000 would be provided at an annual cost of $450,000. The economic benefits of the proposed project action exceed the costs by a ratio of 1.32 to 1.0. POSITIVE IMPACTS: While only 13 residences and 4 businesses would receive complete protection up to the 100-year storm event, the remaining 100 homes and 14 businesses would benefit from lower damages in all floods, especially the more frequent events. Health and safety hazards would be totally eliminated for 37 residents and reduced for 288 residents and 2,500 people employed by businesses located on the floodplain. The two multipurpose dams would also provide an additional safe yield of 2.57 million gallons per day (mgd) to the Coatesville municipal water supply system. This would eliminate the current 1.45 mgd safe yield deficit and would provide an adequate water supply to meet projected demands beyond the year 2000. Approximately 55 percent of the terrestrial habitat losses would be mitigated by improving the wildlife food and cover on 28 acres. Wetland and aquatic habitat would also increase. Employment resulting from project construction would total 64 person-years. NEGATIVE IMPACTS: As a result of project construction, an 80-acre impoundment would be created on Birch Run and a 54-acre impoundment on Rock Run. On the Birch Run and Rock Run sites, terrestrial habitat would be lost due to construction, and there would be a temporary increase in erosion and sedimentation.

AN - 36380536; 1244 AB - PURPOSE: Implementation of a plan to solve flooding and other water-related resource problems in the Howard Creek watershed, located in Greenbrier County, West Virginia, is proposed. The preferred alternative would consist of land treatment measures, channel work, and a floodwater retarding dam. The primary purpose would be to provide watershed protection and flood prevention. The recommended plan consists of 2,910 feet of channel work on Howard Creek, to be 55-feet wide from Garden Street to the Big Draft Road bridge and then 85-feet wide from Big Draft Road bridge to the Greenbrier Avenue bridge. It would include 1,615 acres of conservation land treatment for watershed protection. The cost of installing the recommended plan is estimated at $8.3 million. Annual benefits are estimated at $961,600. POSITIVE IMPACTS: The recommended plan would provide an opportunity for employment and recreation, would improve the health and welfare of watershed residents, and would result in watershed protection and flood prevention. The total acreage benefitting would be 1,753. Approximately 138 acres of primarily urban land, along with 79 houses and 5 businesses, would be protected from the 100-year flood. Construction activities would create 163 man-years of employment. Land treatment measures would reduce upland erosion and sedimentation in Howard Creek. Accessibility to emergency services would be improved. NEGATIVE IMPACTS: Installation of this alternative would require approximately 147 acres of land, 3 houses, several outbuildings, and relocation of a road and utilities for the dam on Dry Creek. The channel work on Howard Creek would take an average width of 15 feet of backyards. Approximately 3,950 feet of Dry Creek and 147 acres of wildlife habitat would be altered by the dam. Stream erosion, turbidity, noise, and air pollution would temporarily increase during project construction.

AN - 36403559; 1231 AB - PURPOSE: Harbor development at Chignik, Alaska, located on the Pacific side of the Alaska Peninsula at the head of Anchorage Bay, is proposed. Since Chignik is accessible only by air or sea, no boat launching facilities would be required. One structure would be needed to provide necessary protection for the inner harbor. A 1,460-foot rubblemound breakwater would be developed for a nonbreaking wave height of 8.5 feet. The side slope of 1 vertical to 1.5 horizontal would be stable; design crest elevation would be 20.5 feet Mean Lower Low Water. The mooring area would total 4.8 acres, using conventional double-berth mooring for 55 vessels from 31 to 60 feet long, and single- and double-berth mooring for 15 larger vessels up to 120 feet long or more. The entrance and access channel area would be approximately 3.6 acres; it would be cut through the nearshore zone and would be subject to the erosive effects of wave conditions. The length-to-width ratio of the basin would be 2.3. Circulation would be improved by several design characteristics. The entrance would be aligned so that the inflow direction is parallel to the long axis of the basin, designed to allow two-way traffic for the 85-foot design vessel. A staging area of 4.4 acres would be needed for minimal parking, gangway access, and some storage. The total area covered would be 26 acres. Total project costs are estimated at $9.7 million to construct, with a benefit-to-cost ratio of 1.2. POSITIVE IMPACTS: Under the preferred alternative, the harbor would provide protection at all times for vessels 30 feet to more than 120 feet long. The breakwater and inner harbor facilities would be designed for a 50-year storm event. The harbor would allow the local fishing fleet year-round harborage in Chignik. Residents in the area would be less dependent on private docks for anchorage and storage. A harbor would benefit the economy of the region. NEGATIVE IMPACTS: Indirect wildlife effects would be caused by close proximity to the harbor, such as increased noise, littering, and human traffic. Intertidal/subtidal habitat would be lost by dredge and fill activities, amounting to approximately 26 acres. There would be a significant impact on locally used clam beds. Harbor related pollutants could enter harbor waters. Passerines, waterfowl, shorebirds, and seabirds might be dislocated because of construction activities and harbor operation. Maintenance dredging would be necessary over the life of the project.

AN - 36400295; 1233 AB - PURPOSE: Implementation of a plan for supplementing the existing dry-year and emergency water supply capacity to the San Diego Aqueduct System is proposed. The preferred alternative would involve construction of a dam along the Santa Ysabel Creek and inundation of Pamo Valley for emergency and dry-year water storage. The reservoir would have a capacity of 130,000 acre feet of water. Major components of this plan include construction of a 264-foot high roller-compacted concrete dam with a built-in spillway; installation of a 54-inch, 19-mile pipeline from the reservoir west to the Second Aqueduct; installation of a 36-inch pipeline intertie to Lake Sutherland with a hydroelectric facility; establishment of a fishing concession and limited day-use picnic area by the city of San Diego; mitigation for project-associated impacts to environmental resources, including compensation for impacts to biological resources; minimization of water and air quality effects during construction; water releases and water reclamation to improve water quality and to maintain water supplies; and reduction of impacts to cultural resources through a multiphased mitigation program. The estimated costs would be $84.7 million, plus $16,000 for a water reclamation project. POSITIVE IMPACTS: The project would guarantee the reliability of San Diego's regional water supply during emergencies and drought situations. Hydroelectric energy would be developed to reduce the demand for other energy resources. The project would create new recreational opportunities. NEGATIVE IMPACTS: Construction of pipelines would involve trenching that would temporarily alter the physiography and potentially increase sedimentation of downstream areas. There would be a short-term decline in water quality during construction. A direct and permanent loss of all vegetation would result within the inundation area, with significant adverse impacts on wildlife and wildlife habitat. The project would displace 30 residents.

Preparation date: January 23, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED DAVIDS ISLAND PROJECT, LONG ISLAND SOUND, NEW ROCHELLE, WESTCHESTER COUNTY, NEW YORK. AN - 36401729; 1237 AB - PURPOSE: Development of Davids Island, located in the western section of Long Island Sound in the city of New Rochelle, Westchester County, New York, is proposed. The proposed development plan would include construction of a bridge from the mainland to the island and associated bridge access roadways on the mainland, construction of 2,000 residential units and supporting nonresidential activities, construction of a marina and beach, provision of utilities, construction of a helipad, and improvements to the South Channel. The fixed-span bridge would be 3,465 feet long, commencing at the Fort Slocum Dock area and proceeding in an easterly direction along a route that brings the structure adjacent to the most northern area of Glen Island and over a 0.48 acre area of parkland that is normally covered with water at mean high water and exposed at mean low water. Two bridge pile foundations would be placed within this area. The mainland approach to the Davids Island Bridge would be designed to provide two-way circulation. The residential units would include supporting retail, recreation, and open space uses. Population on the island is projected to be 3,701 persons. The western and southern shoreline of the island would be developed as a marina accommodating 800 slips for use by island residents. POSITIVE IMPACTS: The city of New Rochelle would derive substantial economic benefit from the development of Davids Island. The long-term consequences of placing the island into development represents a conversion from its current status as undeveloped, underutilized, and blighted lands. Access to and from Westchester County's Glen Island park would improve, and traffic backup on local streets would be reduced. New jobs, income, and housing would be produced. There would be a substantial increase in public tax revenues over and above public costs for the project, and New Rochelle's image would improve as a waterfront community in proximity to New York City. NEGATIVE IMPACTS: The primary negative impacts resulting from the development would include navigational and boating constraints associated with the clearance restrictions of the Davids Island Bridge, increased project-related traffic volumes on the mainland roadway system with consequent increases in vehicular exhaust emissions and vehicular noise; the need for additional sewage treatment capacity at the New Rochelle plant, and impacts to the marine environment from dredging and rock blasting.

Preparation date: January 21, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HUDSON RIVER PCB RECLAMATION DEMONSTRATION PROJECT, NEW YORK (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1982). AN - 36394688; 1238 AB - PURPOSE: Implementation of a project to reclaim sediments that are contaminated with polychlorinated biphenyl (PCB) from the Hudson River in New York is proposed by the New York State Department of Environmental Conservation (NYSDEC). The final environmental impact statement (EIS) recommended the dredging and long-term encapsulation of the PCB-contaminated elements. The project was not implemented, however, when use of the encapsulation site was prohibited because construction of the contamination cell would violate local zoning ordinances. A 1984 sediment sampling project conducted by NYSDEC confirmed the continued presence of significant quantities of PCBs in the Thompson Island Pool. A new disposal site was recommended in an area zoned for industrial use, adjacent to the town of Fort Edward's sanitary landfill. It is estimated that approximately 51,000 pounds of PCBs remain in the top meter of the river bottom sediments. Water column sampling indicates that, during the water years 1981 to 1984, approximately 55 percent of the PCBs reaching Waterford originated in the river between Schuylerville and the upper end of the Thompson Island Pool at Fort Edward. Fish sampling data confirm that the Thompson Island Pool is the major source of PCBs entering the water column. The proposed action, outlined in this supplement, entails the hydraulic dreging of PCB-contaminated sediments, containing an estimated 24,000 pounds of PCBs from the Thompson Island Pool section of the Hudson River, and then transporting the dredged material to a specially designed upland containment facility located in the town of Fort Edward in Washington County. The containment cell would have a capacity of 400,000 cubic yards (cy), and approximately 360,000 cy of hydraulically dredged sediments would be pumped to the site as a slurry. The additional capacity would be used for the disposal of the roughing pond and water treatment structures and for contingency purposes. POSITIVE IMPACTS: The net removal of 22,840 pounds of PCBs would significantly reduce a major source of water-column PCBs. Removal of the sediments contaminated with PCB, which have been experimentally shown to have a wide range of toxic effects, would relieve the area of a potential health hazard. NEGATIVE IMPACTS: During the dredging operation, increases in ambient water-column PCB levels are expected. Some short-term increases in larval and juvenile fish PCB body burdens can be expected. During hydraulic dredging operations, the ambient water-column PCB levels immediately downstream of the operation could increase. The proposed action is likely to result in short-term, construction-related impacts to air quality and ambient noise levels. Long-term impacts to wildlife would be limited to displacement of birds, small mammals, reptiles, and amphibians presently occupying the site.

Preparation date: January 20, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BLANCHARD RIVER FLOOD PROTECTION PROJECT, OTTAWA, PUTNAM COUNTY, OHIO. AN - 36387469; 1239 AB - PURPOSE: A program of flood protection for the village of Ottawa on the Blanchard River in Putnam County, Ohio is proposed. Of the nine alternative plans developed, Plans B, C, and E (a combination of B and C) were selected for detailed study; Plan E has been tentatively selected for construction. Plan B includes channel clearing and snagging, embankment and power line removal, use of excavated material to fill low areas along the proposed floodway, and provision of a floodway. Plan C, a nonstructural alternative, would involve installation of an automated early-warning gauge on the Blanchard River at the Oak Street Bridge and modification of the existing gauge at Findlay, Ohio; operation and maintenance of flood-warning sirens, activated by the automated gauges; distribution of plastic floodproofing crates to property owners as needed and requested; enhancement and modification of local equipment and programs as necessary, with the use of tone-alert radios, intercoms, and emergency coordinators, preflood seminars, data processors, and preparedness brochures; and designation of a public employee as a Flood Emergency Director. Total project costs are estimated at $1.2 million, with a benefit-to-cost ratio of 1.1. POSITIVE IMPACTS: Flood damages would be reduced, increasing health and safety. Commercial activities and related employment would experience less frequent flooding, as would residential areas. Flood damages would be reduced by an estimated $17,000 annually by Plan C and by $116,000 annually by Plan B. There would also be fewer interruptions to public facilities and services. NEGATIVE IMPACTS: The proposed plan would result in selective clearing of two miles of wood streambank habitat; disturbance of 115 acres of upland habitat; degradation of aquatic habitat; increased turbidity; and decreased instream feeding and shelter sites. Embankment removal would subject wetlands to river flood and siltation, with eventual loss of the wetland area. There would be possible disturbance of summer nursery roost habitat for the Indiana bat, a threatened and endangered species. Water quality would be affected by increased summer water temperatures and decreased dissolved oxygen content. Destruction of potentially significant archaeological sites along haul roads and access routes would be possible. Long-term adverse effects on aesthetic qualities of the area would result from riparian corridor modification.

AN - 36400965; 1217 AB - PURPOSE: Construction of a new location connector from S.R. 371 in Forsyth County to I-84 in Gwinnett County, Georgia is proposed. The project consists of two sections. The first section would be a two-lane highway on four lanes of rights-of-way, beginning at S.R. 371 between Kelly Mill Road and Bentley Road and extending to S.R. 400 in Forsyth County. The second section would consist of a four-lane divided highway with a 92-foot-wide grass median, beginning at S.R. 400 in Forsyth County between Pendley Road and Old Atlanta Road and extending southeasterly to I-85 in Gwinnett County. The total length of the project would be approximately 18.3 miles. Each section would be a fully controlled-access facility on a minimum of 400 feet of rights-of-way. This arterial would carry a design speed of 70 mph, a 3 degree maximum curvature, and 3 percent maximum gradient. The estimated cost of the project is $124 million, approximately $15 million for section one and approximately $109 million for section two. POSITIVE IMPACTS: The project would reduce travel time and improve vehicle efficiency for commuters and local users. Access for emergency vehicles would also improve along the project corridor. The project would interconnect and establish energy efficient and time-saving links between resources, industries, and markets, which would encourage a positive and stable base for future economic growth. NEGATIVE IMPACTS: Six wetland areas would be impacted. Approximately 561 acres of farmland would be displaced, as would 36 owner-occupied residential units, 3 owner-occupied summer residential units, 1 tenant-occupied residential unit, 57 tenant-occupied mobile homes, 1 tenant-occupied business and residence combined unit, 4 owner-occupied business units, and 3 tenant-occupied businesses. Noise abatement criteria would be exceeded at 26 residences in locations that are presently quiet and undeveloped. All phases of construction would contribute to air pollution from dust and exhaust emissions. Implementation of the proposed project would require additional rights-of-way, which would slightly decrease the existing tax bases in the affected counties. There would be some unavoidable inconveniences to motorists due to construction activities.

AN - 36400980; 1240 AB - PURPOSE: The Portland General Electric Company (PGE) has applied to the Army Corps of Engineers for a permit to dredge in navigable waters of the United States and to fill in wetland areas. Material, primarily sand, would be dredged from the Columbia River and used to fill a 496-acre site on West Hayden Island above the 100-year flood elevation, making it suitable for development as marine industrial sites. Approximately 2.0 million cubic yards (mcy) of the required fill material would come from dredging in the Columbia River; the remaining 6.5 mcy would come from the project site by excavating a 64-acre area to a depth of up to -45 feet Columbia River Datum (CRD), creating an aquatic basin adjacent to the Oregon Slough. Basin excavation would occur out to the existing channel in the Oregon Slough. The proposed development would also include construction of a bridge over the Oregon Slough, an extension of utilities to the site, and construction of on-site land transportation facilities. Six alternative site development plans were considered, but three were rejected because they were neither economically feasible nor environmentally acceptable. Therefore, only three development alternatives are considered in detail in this final environmental impact statement, as well as the No Action Alternative. Alternative A, the Basin Plan, is the applicant's preferred alternative, which would provide the maximum waterfront development, with flexibility to respond to a wide variety of marine uses. Alternative B, the Modified Basin Plan, is a variation of Alternative A, the difference being that 132.3 acres of land around the basin would be left in a natural state; this would also eliminate approximately 4,820 feet of waterfront for marine uses. Alternative C, the North Shore Plan, would involve development only on the north shore and provide only large marine sites; approximately 50 percent of the waterfront would not be developed. POSITIVE IMPACTS: Benefits to the local and regional economies would include an estimated 658 to 1,469 jobs and an increased local tax base. The bridge and road improvements would connect West Hayden Island to the interstate freeway system and major local arterials. Filling of the site would provide flood protection. NEGATIVE IMPACTS: Dredging would affect approximately 35.5 acres of shallow water habitat adjacent to the basin and 3.1 acres in the authorized channel of the Oregon Slough. Benthic habitat and organisms would be destroyed by the dredging; up to 77 acres of wetlands would be filled, requiring off-site mitigation; other terrestrial habitat such as cottonwood-ash riparian habitat would also be filled; the natural appearance of West Hayden Island would be replaced by man-made features and industrial development; and traffic would increase on local streets and highways in the vicinity.

OLIVE BYPASS TO I-40 NEAR FAISON, WAYNE, DUPLIN, AND SAMPSON COUNTIES, NORTH CAROLINA: STATE PROJECT NO. 8.1240601, R-606; FEDERAL-AID PROJECT NO. F-83-2(20). AN - 36394707; 1223 AB - PURPOSE: Construction is proposed of a US 117 connector from the Mt. Olive Bypass to the proposed I-40 highway near Faison in Wayne, Duplin, and Samson counties in North Carolina. The proposed action consists of two parts. The first part would widen 3.5 miles of the existing two-lane US 117 to a four-lane divided facility from the intersection of NC 55 at Mt. Olive to the north end of the existing four-lane divided section at Calypso. The second part would construct a four-lane divided facility on new loation from Calypso to I-40, using one of the four alternates being considered, namely, 1, 2D, 2E, and 3B. Three of the four alternates begin just north of the intersection of US 117 and SR 1006 near Calypso. Alternate 1 runs southwest for a short distance and turns west to intersect I-40 in the vicinity of Giddensville in Sampson County. Alternate 2D roughly parallels Alternate 1 until near its intersection with SR 1302; it then turns southwest to intersect I-40 at the I-40/NC 403 interchange. Alternate 2E runs southwest until its intersection with NC 50 north of Faison and then turns west to intersect I-40 at the interchange of I-40 and NC 403. Alternate 3B begins just south of the bridges over the Seaboard Coast Line Railroad, runs southward to its intersection with SF 1332, and then turns southwest to cross existing US 117 and intersect I-40 between SF 1904 and SR 1905 in Sampson County. The project length ranges from 9.3 to 10.4 miles, depending on the alternate. Estimated average annual daily traffic on the proposed project is expected to range from 2,900 to 5,800 vehicles per day in 1986 and from 5,500 to 10,400 vehicles per day in 2006. The design speed is proposed to be 70 miles per hour. The proposed cross section for widening the existing two lanes would be two 24-foot width pavements separated by a 30-foot grass median. This cross section would allow construction to be contained within the existing rights-of-way. The new location section would have two 24-foot pavements separated by a 46-foot median, which is in compliance with current design policy. The proposed shoulder width is 10 feet usable (2 feet paved). Partial access control, defined as full control of access at abutting properties with access points at designated intersecting roads only, is proposed for the entire project. Each of the four alternates would require drainage structures; two would require new interchange structures and the other two would require modifications to existing interchange structures. Improvements to the two existing bridges on US 117 over the Seaboard Coast Line Railroad would be a part of this project regardless of the alternate chosen. The bridge on the northbound lane would be replaced, and the bridge on the southbound land would be rehabilitated. Staged construction is not recommended for this project; however, since additional rights-of-way will not be required for widening of the 3.5 miles of the existing two-lane facility, it may be possible to let the contract for it at an earlier date than the new location section. Costs are estimated at $14.9 million to $21.0 million, depending on the alternate selected. POSITIVE IMPACTS: The primary benefits would be economic gains resulting from the improvement in highway transportation. Safety benefits would also be realized due to the construction of the four-lane connector to I-40. This would reduce the amount of traffic currently traveling through the town of Faison and result in reductions in travel time, fuel consumption, and vehicle operating costs. NEGATIVE IMPACTS: Adverse impacts would include the displacement of three to four homes and possibly one business, depending on the alternate chosen. There would most likely be an increase in the noise level due to widening of the highway. An estimated 19.54 to 48.48 acres of wetlands would be impacted, and an estimated 117.1 to 206.8 acres of prime and locally important farmland would be taken for rights-of-way, depending on the alternate. Temporary adverse impacts would result from some erosion and siltation, construction noise, and public inconvenience during construction.

Preparation date: January 12, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COUNTY STATE AID HIGHWAY (CSAH) 18 FROM INTERSTATE 494 IN HENNEPIN COUNTY TO TRUNK HIGHWAYS 13 AND 101 (COUNTY PROJECT NUMBER 6816), SCOTT COUNTY, MINNESOTA. AN - 36386580; 1221 AB - PURPOSE: Completion of the six-mile segment of County State Aid Highway (CSAH) 18 from Interstate 494 (I-494) in Hennepin County south to Trunk Highways (T.H.) 13 and 101 in Scott County, Minnesota is proposed. The proposed action would replace the existing CSAH 18 roadway and the existing Bloomington Ferry Bridge, scheduled for removal by December 31, 1989. The replacement roadway (arterial or freeway) would be four lanes wide. Six build alternatives and a no-build alternative are being considered. All of the alternatives, including the no-build alternative, include the removal of the Bloomington Ferry Bridge; all have a common alignment from I-494 south to 108th Street South (Old Shakopee Road), a distance of approximately four miles. From this common point, the alternatives diverge. Three corridors contain all of the six build alternatives. The west corridor proceeds predominantly south from the common point to a junction with T.H. 101 and provides an arterial, freeway, or one of the crossings of the dual crossing alternative. The central corridor proceeds southeast from the common point to the junction of T.H. 13 and T.H. 101, which provides an arterial and freeway configuration. The third build corridor, the Normandale corridor, is an extension south of Normandale Boulevard in Bloomington to T.H. 13, and would provide an arterial alternative and the other leg of the dual crossing alternative. Build Alternative 5, an arterial roadway in the western corridor, was selected as the preferred alternative. It would provide an arterial roadway from I-494 to T.H. 101 in the west corridor alignment south of CSAH 18, passing between Fisher Lake and Rice Lake, joining T.H. 101 in Shakopee. Construction costs are estimated at $56 million for bridges and $38 million for roadways. POSITIVE IMPACTS: In addition to replacing a superannuated, substandard structure crossing the Minnesota River, the project generally would support local and regional transportation systems. Commuter trips between the city of Minneapolis and northern Scott County would be shortened. The temporary replacement bridge, which carries traffic formerly carried by the Bloomington Ferry Bridge and which constitutes an encroachment on the navigational channel of the river, would be removed. NEGATIVE IMPACTS: Rights-of-way development would displace 5 houses, 4 businesses, and 42 employees. An estimated $29,800 in property taxes would be lost. Historic properties affected by construction would include the Barden Station Site, the Samuel McClay House, and the Bush Lake School. Destruction of the Bloomington Ferry Bridge would be required; historic values associated with this site would be lost or degraded. State noise standards could be exceeded at some noise-sensitive sites. The project would cross the floodplain of the Minnesota River and displace 37 acres of wetlands. Numerous recreational and park areas would be traversed by the highway.

Preparation date: January 12, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - METROPOLITAN DENVER WATER SUPPLY SYSTEM, COLORADO. AN - 36404623; 1235 AB - PURPOSE: Application for permits has been made by the Denver Board of Water Commissioners (DWB) for the 1.1 million acre-foot Two Forks Reservoir and for an extension of its Williams Fork Gravity Collection System. These are considered to be two separate and distinct applications. The Metropolitan Water Providers (Providers), composed of more than 40 cities, water and sanitation districts, and one county in the Denver metropolitan area, are cosponsors of the Two Forks project. The area includes all or parts of Denver, Adams, Arapahoe, Douglas, Jefferson, Boulder, and Weld counties in Colorado. The Two Forks damsite is located on the South Platte River approximately one mile downstream from the confluence of the North Fork of the South Platte River with the South Platte River. The Two Forks Reservoir would provide long-term storage of natural flows from the North Fork of the South Platte River and the South Platte River and would also store flows from existing west slope collection systems that deliver water to the North Fork of the South Platte River via Roberts Tunnel. Waters regulated by Two Forks would be diverted at Strontia Springs Dam to the Foothills Water Treatment Plant, to the Marston Treatment Plant, and at specified delivery points for suburban participants that are raw water users. Operation of the reservoir would increase the firm annual yield to the DWB system by 98,000 acre-feet per year. The Two Forks Dam would be a multicurvature, thin-arch concrete dam designed to be constructed in either one or two stages. Principal project features would be the concrete arch dam; a free overflow spillway in the center of the dam crest; a spillway plunge pool; a multilevel intake structure on the upstream face of the dam; valving systems for selective withdrawals from the reservoir, including an emergency reservoir drain system; a diversion tunnel and cofferdams for river diversion during construction; electrical transmission lines; and project access roads. The construction cost would be approximately $370 million. The Williams Fork gravity project would be an extension of the existing system. The project would be divided into the South and North sectors. Both sectors would be extensions of the existing gravity-flow system and would deliver water to the Gumlick Tunnel. The extended system would collect water from Darling Creek and the South Fork, Middle Fork, and main stem of the Williams Fork drainage. Extension of the Williams Fork Collection System using the gravity scheme would increase the safe yield of the DWB system by 12,000 acre-feet per year. The total construction cost of the project is estimated to be $87 million. The Two Forks project could be mitigated for costs ranging from $17 million to $109 million. Resources that would require mitigation would be wildlife transportation, recreation, and aquatics. The Williams Fork gravity alternative could be mitigated for costs ranging from $1 million to $22 million. Resources that would require major mitigation expenditures are recreation and visual resources. POSITIVE IMPACTS: The Two Forks dam and reservoir would provide a 12-year supply of water for the Denver metropolitan area. This would be the most cost-effective alternative, with costs ranging from $390 to $465 per acre-foot. The Williams Fork gravity project would provide metropolitan Denver water supply needs for one additional year, at a cost in excess of $600 per acre-foot. This alternative would benefit aquatic life. It would not cause significant impacts to physiography, topography, geology, channel stability, transportation, water quality, threatened and endangered species, or socioeconomic resources. NEGATIVE IMPACTS: Without considering mitigation, the Two Forks alternative would be the most damaging to recreation; threatened and endangered species; vegetation; wildlife; aquatic life; and visual, cultural, and water quality resources. The alternative would eliminate a number of recreational cabins, inundate miles of gold medal trout stream, cause loss of suitable habitat for the pawnee montane skipper butterfly, and eliminate acres of vegetation. It would also eliminate deer and elk winter range and bighorn sheep range.

AN - 36400935; 1234 AB - PURPOSE: Maintenance dredging and clearing by the removal of sediment and riparian vegetation from the San Joaquin River from Friant Dam near Fresno to Stockton, California, a distance of approximately 225 miles, are proposed. The purpose of this revised draft environmental impact statement is to document that the project's environmental impacts have been analyzed and considered for the proposed actions. The revised project consists of channel clearing at selected sites along approximately 35 miles of the river. On the Middle River, the proposed work would consist of selective clearing of false bamboo from the west levee for approximately seven miles downstream from Old River, and the removal of 95,000 cubic yards of sediment from the channel in an approximately three-mile reach downstream from Old River. Elderberry plants would be identified and flagged to ensure avoidance. Proposed mitigation is the acquisition of a seven-acre site along Middle River. In Mendota Pool, the proposed project consists of removal of approximately 150,000 cubic yards of sediment from an area of approximately 15 acres. Work would consist of excavating a channel approximately 200 feet wide from the dam, extending 1,500 feet into the main body of the pool. Proposed mitigation is the acquisition of a seven-acre parcel of agricultural land adjacent to the pool and its conversion to shallow water fish habitat. On the San Joaquin River (Gravelly Ford to Friant Dam), the proposed work consists of removal of approximately 135 acres of flow-restrictive riparian vegetation in and adjacent to the river channel. Proposed mitigation would be the acquisition of a 70-acre site at River Mile 225, a 31-acre site at River Mile 231, a 14-acre site at River Mile 231.5, and a 60-acre site at River Mile 236. Dredging and removal would be accomplished by floating draglines, suction dredges, bulldozers, and front-end loaders. Dredged material would be placed along existing levees, in selected dike disposal areas, or in sanitary landfills. Estimated total first cost of the project is $5.6 million. POSITIVE IMPACTS: Channel clearing would reduce flood levels within the levees in the vicinity of the selected sites and would reduce nearby seepage problems on the land side of the levees. Agricultural efficiency would be increased significantly. NEGATIVE IMPACTS: Approximately 135 acres of riparian vegetation would be removed from the river channel. Increased water turbidity would disrupt fisheries habitat. Work in the Middle River reach would result in the loss of some habitat of the valley elderberry longhorn beetle.

AN - 36400331; 1243 AB - PURPOSE: The Elliott Bay Marina Group has submitted a revised Army Corps of Engineers permit application to develop a small craft harbor and marina on the north side of Elliott Bay at the base of Magnolia Bluff in Seattle, Washington. The site would include 78 acres and approximately 2,800 feet of shoreline. It would provide moorage for 1,200 boats. The project also would include commercial facilities to serve the marina, public-use areas, and accessory parking for approximately 888 automobiles. The moorage basin would be protected from wave action by breakwaters totaling 4,500 feet in length. The marine-activity building would comprise 25,000 square feet and would be located in the center of the development. Two marina storage buildings would be built, two buildings would house security offices and restrooms, and a marina supply building would be located at the public dock. A pedestrian pathway would be constructed along the entire length of the shoreline, with observation points, rest areas, and picnic spots. On-site and off-site marine habitat enhancement areas totaling 19.3 acres would be provided. Under this revised application, the timber pile breakwaters, rubblemound breakwaters, and floats would be shifted eastward toward the Terminal 91 facility. The permit applicant would exchange intertidal areas and shoreline located on the western portion of its property for city-owned intertidal area and shoreline located to the west of Smith Cove Park. Construction is expected to take 12 months. POSITIVE IMPACTS: The project would significantly expand recreational opportunities for residents of the metropolitan Seattle area and would require between 190 and 200 employees to manage the marina and associated facilities. Tax revenues would increase substantially. NEGATIVE IMPACTS: Dredging and deep-water disposal would increase water turbidity. Approximately 9.75 acres of intertidal area and 1.75 acres of upland shoreline would be converted to impervious surfaces. Waterfowl, sea mammals, and upland mammals would be disturbed or displaced entirely. Boat traffic could interfere with Native American fishing. Fugitive dust, as well as a significant increase in noise level, could occur during construction.

Preparation date: January 6, 1987 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - JAMESTOWN BRIDGE REPLACEMENT PROJECT, JAMESTOWN, NEWPORT COUNTY, RHODE ISLAND: STATE ROUTE 138 (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1981). AN - 36406697; 1699 AB - PURPOSE: Replacement of the Jamestown Bridge and its approaches in Jamestown, Newport County, Rhode Island is proposed. The bridge replacement is part of a project involving construction of 40 miles of Interstate 895 (I-895) from I-195 in Richmond, Rhode Island to I-95 in Swansea, Massachusetts. The proposed project would involve construction of two additional lanes on State Route (S.R.) 138 between S.R. 1A and the bridge. On the Jamestown side of the bridge, the four-lane highway would transition into the existing two-lane roadway west of Helm Street. The preferred alternative would be a controlled-access four-lane roadway along Eldred Avenue, with interchanges at Helm Street and North Road, and a new four-lane roadway west of East Shore Road, consisting of four 12-foot travel lanes, a 30-foot median (of which 24 feet would be grassed), 9-foot shoulders, and 30-foot landscaped clear areas. The length of the bridge and its approaches would be approximately 11,000 linear feet. POSITIVE IMPACTS: The bridge would constitute a major transportation link in southeastern Rhode Island for North Kingstown, Jamestown, and Newport. The structure would replace a substandard, two-lane crossing with a modern, four-lane facility that would provide an improved highway for through traffic, local access within existing neighborhoods, and community-wide access. Traffic safety would be enhanced due to provisions allowing buses to avoid crossing the west half of S.R. 138. NEGATIVE IMPACTS: Bridge construction would encroach on the Plum Point Beach area in North Kingstown, and the bridge approaches would lie within a floodprone area. Rights-of-way requirements would result in displacement of one residence each in Jamestown and North Kingstown. The limited-access roadway would tend to make future development along the roadway less attractive owing to the lack of direct access to the roadway. Wetlands would be impacted due to substantial quantities of fill required for the project; as a result, 6.4 acres of wetland habitat would be lost. Approximately 30.4 acres of prime farmland would be impacted.

AN - 36405577; 1236 AB - PURPOSE: Construction of a 30-acre confined disposal facility (CDF) on state property adjacent to the Selfridge Air National Guard Base (ANGB), located on the north side of the Clinton River approximately three miles upstream from the river mouth in Macomb County, Michigan, is proposed. This clay-lined facility would be used to contain the material to be dredged from the Clinton River Federal Navigation Channel, where shoaling has occurred. Total capacity of the 30-acre facility for 10 years is approximately 370,000 cubic yards. In the past, maintenance dredging activities were performed by both mechanical and dredge types. The currently proposed dredging operations would remove the shoaled sediment by mechanical dredge, place the material in a barge, and transport the sediment to an offloading area, where the material would be placed in trucks and hauled to the disposal facility. An offloading/transfer facility would be constructed on approximately 2.5 acres of property leased from Selfridge ANGB. A steel sheet piling wall and a steel-supported concrete platform would be constructed along the river edge, enabling a dredge scow to be unloaded directly into trucks for transfer to the disposal facility. Upon completion of the filling, the clay-lined facility would be filled, then capped with clay, topsoiled, seeded, and revegetated, which would take approximately 10 years. The facility would then be turned over to the Michigan Department of Natural Resources for possible recreational use. A haul road would be constructed to form a loop to the platform for truck entry and exit. The road would remain intact when the property is turned back to the ANGB. The proposed action may also involve construction of one or more temporary structures. The temporary placement of clean fill or construction materials on upland or aquatic areas outside of wetlands may also be necessary. Estimated costs would be $2.2 million. POSITIVE IMPACTS: Construction of a clay-lined disposal facility would effectively seal the polluted dredged material from the environment. Because of the clay liner, groundwater would be effectively sealed off and prevented from contact with dredged material. The dredged channel would allow the continued safe movement of recreational craft, and local benefits would be derived from providing for the various marinas to remain functional. NEGATIVE IMPACTS: Thirty acres of shrub/scrub land would be changed as an upland habitat. The upland habitat that would replace the existing area might be less attractive to the existing flora and fauna. Construction activities may be aesthetically displeasing to residents. Trucking activities would cause some disturbance in the area from traffic, noise, and dust.

Most of the dissolution reactions are critically dependent on the coordinative interactions taking place on these surfaces, above all on the interaction of hydrous oxide surfaces with H(+), OH(-)(surface protonation), and suitable ligands (anions and weak acids). Surface processes rather than transport processes are typically the rate-controlling steps in the dissolution of most hydrous oxides and aluminum silicates; thus, the reaction rates simply depend on the concentration of surface species. Linear dissolution kinetics are observed if the surface protonation and surface ligand concentration remain constant. This indicates that the detachment of the surface metal species is rate-determining. Surface chelates, especially those present as five-membered and six-membered rings, for example, with oxalate or salicylate, are most efficient in enhancing the dissolution reaction.

The method was designed to model the judgement of experienced stage forecasters that have used gage relations successfully in the New Orleans District of the Corps of Engineers for many years. Stages observed at the stations of interest since 1973 were computerized and from this data bank, the River Stage Forecasting System selected the best match for the stages observed at the first upstream station for the prediction period. The selected stages were then routed downstream through the station of interest; the effects of operating a control structure and emergency spillways were factored into the system. The system provided the flexibility to change the initial station and the lag times between stations, and to adjust stages at selected locations. However, there were some factors that an experienced forecaster could introduce into the prediction that would be impractical to incorporate into a computer program. For example, prior knowledge of a floodwave traveling toward the main stream through an upstream tributary can only be introduced into the prediction as a subjectively estimated correction factor. The program developed for this project makes provisions for the manual introduction of correction factors to the predicted stages.

Land use changes (1850-1870) cause aggradation and then degradation, but the channel was in equilibrium by 1900. Gravel mining in Dry Creek and Russian River (1900-1950's) reduced base level of Dry Creek by 3 m. The channel degraded by an average of 3.2 m, and by 1984 mean channel width and depth, at bankfull stage, had increased from 9.8 to 101.8 m and from 1.4 to 5.8 m, respectively. Channel longitudinal profiles were not significantly different; therefore, the major response of Dry Creek to the imposed changes was an increase of width. Dam closure (1983) did not cause the expected further degradation of Dry Creek because of channel armoring, tributary contribution of sediment, emplacement of three grade-control sills, and the presence of bedrock outcrops in the channel.

Correlations of trace element concentrations with the various main components of the settling particles (biological material, calcium carbonate, manganese and iron oxides, silicate minerals) and examination of seasonal variations both of these concentrations in particles and of particle fluxes to the sediments show that biological material is an important carrier phase (especially for Cu and Zn). Iron and manganese oxides also contribute to trace element transport; calcium carbonate is inefficient as a carrier material.

The highest TOC load was found in the bottom ash (2-3 g kg super(-1) MSW), followed by the filter dust (0.1-1.0 g kg super(-1) MSW) and the flue gas (0.05-0.3 g kg super(-1) MSW). The composition and behaviour of the bulk of TOC in these products is not yet known. In order to minimize the risk of leaching organic substances as well as metals due to biological, chemical and physical reactions of the products of incineration in a landfill, it is suggested the incineration process be optimized towards complete combustion.

Water and element balances for the non-metals carbon, nitrogen, fluorine, phosphorus, sulfur and chlorine and the metals iron, copper, zinc, cadmium, mercury and lead were investigated in four municipal solid waste landfills of various ages. Data from these mass balances were then used to develop a method that permits elucidation of the behaviour of landfill in its most active phase, i.e. that in which relatively high gas generation occurs.

AN - 15271002; 2029214 AB - The cataclysmic eruption of Mount St. Helens, Washington, on 18 May 1980, filled nearby Spirit Lake with timber and volcanic debris and completely blocked the lake's natural outlet. The lake, which the outlet had previously kept in hydrological balance, was henceforth impounded in a closed, hydrologically unstable basin by a debris dam 150-180 m thick. This event greatly altered the limnology of Spirit Lake and resulted in extremely poor water quality. Some post-eruption water quality characteristics included whole-lake anoxia, which persisted for months; and extraordinarily high concentrations of sulfides, methane, reduced iron and manganese, phosphorus, and dissolved organic matter. Concentrations of total bacteria were thought to be unprecedented for natural lakes. AU - Larson, D W AU - Glass, M W Y1 - 1987 PY - 1987 DA - 1987 KW - USA, Washington, Spirit L.

However, it required only the type of information normally available in the planning stages of a piping system rehabilitation study. The method was applied to examples of galvanic and impressed current systems. Verification of the procedure using costs of 17 actual projects showed an average 25 per cent difference between the estimated and actual costs.

Quantitation was achieved by reversed-phase HPLC with UV-fluorescence detection. The performances of the different octadecylsilica cartridges, containing equal amounts of packing materials, were comparable with recoveries of LAS and APEO from secondary sewage effluent greater than 80 per cent in all cases. LAS and APEO were determined at concentrations as low as 20 and 4 ug per litre, respectively.

The release of phosphorus from anoxic sediments did not necessarily arise from abiotic reduction of phosphorus-containing iron compounds, net phosphorus retention by sediments did not show a simple linear relationship to the phosphorus content of a lake, and the phosphorus retention capacity of lake sediments was not permanently increased by artificial oxygenation of a previously anoxic hypolimnion. Artificial oxygenation as such was not able to produce a reduction of trophic state.

Prepacked bonded-phase octylsilica and octadecylsilica columns were used to determine homologue and isomer distributions, respectively. Compared with commercial detergent products, influents had a higher abundance of shorter homologues and inner isomers whereas the digested sludges had more longer homologues. Two different homologue-isomer distributions were found among the effluents. In treatment works where LAS elimination was 99 per cent, the distributions were similar to those of digested sludges.

AN - 36394486; 1179 AB - PURPOSE: Improved highway access to the Quonset Point/Davisville (QP/D) industrial complex in North Kingstown (Washington County) from the existing Route 4 freeway in East Greenwich (Kent County), Rhode Island is proposed. The need for this improved access centers around the projected growth of the QP/D as one of the largest industrial parks in that region of the country. General build alternatives considered in the study are the Freeway Alternative and the Upgrade Alternative. Three Freeway Alternatives, as well as a No Build Alternative, have been suggested; all three build alternatives follow the same general concept of connecting Route 4 in the vicinity of the existing Route 4/Frenchtown Road/Davisville Road interchange with Roger Williams Way at QP/D. They all contain three interchanges located at Route 4, at the proposed West Davisville Access Road, and at Post Road (Route 1). From the point where the three alternatives cross AMTRAK to the southerly terminus at Roger Williams Way, they are identical. The Upgrade Alternative is defined as the upgrading of Davisville Road and Devils Foot Road, calling for widening from the present two lanes to a four-lane facility. The widened roadway would contain 10-foot shoulders, as well as curbs and sidewalks, on both sides. The widening would take place essentially on the existing alignment. Estimated costs range from $16.1 million for the Upgrade Alternative to $27.1 million for Freeway Alternative 2. POSITIVE IMPACTS: Any of the Freeway Alternatives would divert through traffic from Davisville and Devils Foot roads, leaving only local traffic on the existing roadway. The result would be good traffic operations on both the new freeway and the existing roadways. The Upgrade Alternative would increase capacity, but some marginal traffic operations would still exist. The Freeway Alternatives would enhance the residential environment by removing significant traffic volumes from Davisville and Devils Foot roads. NEGATIVE IMPACTS: All four build alternatives would require rights-of-way acquisition and the use of various amounts of federally owned land. From 8 to 10 residential units and 4 or 5 businesses would have to be relocated, depending on the alternative selected. Relocation may not be possible for three of the businesses affected. The Upgrade Alternative would have major negative effects on residential neighborhoods along the Davisville Road/Devils Foot Road corridor. All build alternatives would result in immediate job losses due to business displacements. All build alternatives would require some filling within the 100-year floodplain; in all cases, however, replacement of lost floodplain could be achieved. Freeway Alternative 4, crossing the Hunt River, would fill approximately 5.8 acres of the Fry Brook wetlands. These impacts would be mitigated by bridges or by wetlands replacement. The Upgrade Alternative would impact the Old Davisville Historic District.

Preparation date: December 23, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SHINNECOCK INLET NAVIGATION PROJECT AT SOUTHAMPTON, LONG ISLAND, SUFFOLK COUNTY, NEW YORK. AN - 15225499; 1196 AB - PURPOSE: The implementation of a project designed for improved navigation, beach erosion control, and water quality improvement are proposed for Shinnecock Inlet and vicinity, Long Island, Suffolk County, New York. The recommended plan consists of a 200-foot wide navigation channel with a design depth of -10 mean low water (MLW), which would be enveloped by a deposition basin 800 feet wide, dredged to -20 MLW for advanced maintenance. The oceanward 200-foot section of the west jetty and the jetty section (approximately 200 feet long) at the northern end of the east jetty, where there has been partial or complete washout, would be repaired. In addition to the work recommended on the jetties, 260 feet of revetment northeast of and adjacent to the east jetty would replace a washed out section of revetment. The recommended plan would also include 3,700 cubic yards of initial construction dredging at the fishing facility dock area to assure necessary depths for navigability at currently shoaled areas. This dredging would be accomplished by clamshell dredge and disposed to the east of the inlet as part of jetty rehabilitation construction. In addition, the plan includes pumping dredged material equivalent to 61,000 cubic yards annually for each dredging operation on the beachfront within 3,000 feet west of the inlet and pumping the remaining dredged material offshore, approximately 5,000 feet west of the inlet. Periodic dredging of the deposition basin would be required for advanced maintenance of the channel. In order to estimate future channel maintenance requirements and also to document the results of the construction, it is proposed that the project be monitored for 10 years after construction. Based on the detailed design, the annual cost of this plan would be $3.4 million and the annual benefits would be $6.5 million, resulting in a benefit-to-cost ratio of 1.8. POSITIVE IMPACTS: Repair of the jetties should have a positive effect on finfish resources. The proposed project would provide a safe navigation channel through Shinnecock Inlet for recreational deep sea fishing. NEGATIVE IMPACTS: Dredging would cause unavoidable temporary turbidity and sedimentation. Benthic habitat would be disrupted by the proposed dredging and disposal. Some habitat areas would be converted to other habitat types and would develop a different community of species than was present prior to the work.

AN - 15226059; 1188 AB - PURPOSE: The final supplement to the final environmental impact statement of July 1980 updates the description of the impacts that are expected to result from widening and deepening the Sacramento River Deep Water Ship Channel from New York Slough to the Port of Sacramento. The selected plan consists of deepening the channel from 30 to 35 feet from New York Slough to the Port of Sacramento; widening the channel from 300 to 350 feet between New York Slough and Junction Point (channel mile 15.0) (the existing 300 foot width between Junction Point and channel mile 18.6 would remain the same), and from 200 to 250 feet from channel mile 18.6 to the Port of Sacramento; and disposing of dredged material on 15 disposal sites located on both sides of the entire channel and totaling 4,464 acres. Approximately 21.5 million cubic yards of dredged material would be excavated using hydraulic suction dredges. Included also would be fish and wildlife mitigation and recreation development plans, but no recreation component due to lack of a local sponsor. The fish and wildlife navigation plans involve the creation of 63 acres of wetland (open water mudflat or beach bar, emergent marsh, and riparian) habitat to compensate for habitat lost in channel widening and any temporary loss of habitat at disposal sites. The project would also include implementation of a water quality monitoring program and construction of a submerged sill or alternative features if a significant and measurable increase in salinity is identified. POSITIVE IMPACTS: Implementation of the selected plan would result in transportation cost savings by allowing movement of cargo via larger ocean-going vessels with their inherent economies of scale, through elimination of excessive tidal delays, by reducing present light-loading and topping-off practices, and through movement of project-induced tonnage. Wetlands would be created for enhancement of the fish and wildlife resources of the project area. NEGATIVE IMPACTS: Significant adverse impacts include the temporary loss of 52 acres of marsh and riparian habitat adjacent to the ship channel. There are no other significant or long-term impacts associated with the project.

Preparation date: December 22, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - US 311 BYPASS, HIGH POINT EAST BELT FROM US 311 NORTH OF HIGH POINT TO US 311 SOUTH OF ARCHDALE, GUILFORD AND RANDOLPH COUNTIES, NORTH CAROLINA: FEDERAL PROJECT NO. F-119-1(1); STATE PROJECT NO. 8.1570601 (R-609). AN - 15227764; 1176 AB - PURPOSE: Construction of a US 311 bypass of the cities of High Point and Archdale, in Guilford and Randolph counties, North Carolina is proposed. The proposed bypass would be a multilane freeway on new location and would begin at the existing US 311 freeway north of High Point and end at a point on existing US 311 south of Archdale. The total length of the project varies from 13.3 to 14.3 miles, depending on which alternative is selected. The northern section (Section I) of the proposed action extends from the existing US 311 freeway north of High Point, traverses in an easterly direction to Johnson Street, southeasterly to Eastchester Drive and Greensboro Road, and then southerly to US 29 and US 70, which are south and east of High Point's central business district. Section I has a total length of 7.6 miles and approximately 40 percent of the rights-of-way have been acquired. In the southern section (Section II), four alternate corridor alignments have been determined to be feasible. These alternates vary in length from 5.7 to 6.7 miles and are located east of Archdale, extending from US 29 and US 70 to existing US 311 south of Archdale. Total costs range from $104.8 million to $108.5 million. POSITIVE IMPACTS: The plan would provide a needed bypass for the cities of High Point and Archdale in the north-south corridor and would complete a freeway connection between I-40 and I-85 in the western Triad area. The proposed action would slightly improve air quality in the project area. Some wildlife and wildlife habitat may be positively affected by mitigation measures. NEGATIVE IMPACTS: Noise levels would increase along the proposed corridor. There could be potential adverse impacts on the public water supply, which would occur if silt and pollutants associated with heavy equipment and building materials are allowed to enter the streams and reservoirs during construction. Long-term adverse impact would occur if traffic-generated pollutants and hazardous materials are allowed to enter the water supply from highway runoff. The bypass would have unavoidable impacts on the floodplain in the project area. The alignment encroaches on the flood fringes and floodways of several water courses and would require some channel relocation and a causeway across Oak Hollow Lake. The plan would remove 500 to 600 acres of woodland. Construction of a causeway and/or bridges would create a barrier between the western portion of the arm and the remainder of Oak Hollow Lake. From 12.5 to 14.0 acres of wetlands may be involved. Section I would require relocation of 129 dwelling units. The total number of residential relocatees varies from 169 to 201, depending on the alternative selected. Thirteen to 16 businesses and 2 or 3 churches would also be relocated by the proposed action.

AN - 36400214; 1197 AB - PURPOSE: Information pertaining to maintenance of the Atlantic Intracoastal Waterway (AIWW) from the Cape Fear River to the South Carolina state line, tangents 1 through 28, in Brunswick County, North Carolina is provided in this supplemental information report. Maintenance dredging by hydraulic pipeline dredge would be used to remove isolated shoals lying above the plan of 14 feet below mean low water in the AIWW from the Cape Fear River to the South Carolina state line. Material consisting of silt, clay, sand, and some shell would be dredged and disposed of in the various tangents. Previous maintenance of the above areas of the AIWW was performed by hydraulic pipeline dredge, and the dredged material was discharged into upland diked disposal sites and/or beach disposal sites. The frequency of dredging in this section of the AIWW ranges from annual to once every 8 to 10 years. Maintenance of this section of the AIWW would be performed as part of the overall maintenance of the AIWW from Morehead City, North Carolina to the South Carolina state line, which requires approximately seven to nine months to complete each year. Beach disposal of dredged material would be timed for completion prior to the sea turtle nesting season, May 1 through November 31. If beach disposal during the nesting season cannot be avoided, monitoring will be performed. POSITIVE IMPACTS: The proposed project will assist in maintaining the AIWW. No impacts are expected to archaeological or historical resources. NEGATIVE IMPACTS: Effluent from some disposal areas would be discharged into areas open to shellfishing.

AN - 36397726; 1199 AB - PURPOSE: The flooding problems in the Rio La Plata Basin at Toa Alta, Toa Baja, and Dorado, Puerto Rico are addressed. The preferred alternative proposes a combination of levees and channel improvements to be constructed to protect against the Standard Project Flood (SPF) occurrence. Under this plan, the existing channel would be realigned and improved to provide a bottom width of 50 meters (164 feet) and side slopes of 1 on 4. The bottom elevation would vary from 6 meters (19.7 feet) below sea level to 5.5 meters (18 feet) above mean sea level. The town of Toa Alta and San Jose community would be protected by ring levees. An additional levee adjacent to Highway 693 is proposed at the west, connecting the ring levees at Mameyal and Dorado and extending to the south to high lands near Highway No. 2. POSITIVE IMPACTS: The proposed plan would improve the flooding situation of the Santa Elena archaeological site for high-frequency floods by providing a more efficient channel. The levees would provide more than 5,000 acres of enhanced floodplains. LEGAL MANDATES: Potential archaeological sites would be affected due to the channelization proposed. Excavation for the proposed channel would affect mostly sites within the levees, while the levees may cover some of the other sites. Adverse impacts to the vegetation at the river edge, typically water hyacinth, "pampano," and cana brava may occur. The proposed plan would cause temporary adverse impacts on water quality due to turbidity generated by construction activity.

Preparation date: December 15, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED PLAN FOR FLOOD CONTROL AND RELATED PURPOSES, COLDWATER CREEK, SAINT LOUIS COUNTY, MISSOURI. AN - 36394815; 1194 AB - PURPOSE: Flood damage reduction and related improvements in the Coldwater Creek watershed, located in Saint Louis County, Missouri, is proposed. The primary focus of the study is flooding problems. The recommended plan also addresses streambank erosion problems, outdoor recreation opportunities, and environmental quality concerns as they relate to potential flood damage reduction improvements. The tentatively preferred alternative is a combination of channel widening and tunnels, small levees, and recreation components, together with a flood forecasting and warning plan. The plan was designed to result in essentially no induced flood damage. Ten miles of channel widening, enlarging the opening through a downstream railroad embankment, and two small levees would be included in the plan. Other features would include 8.10 miles of hiking and biking trails, 16 picnic tables, two picnic shelters, and a four-foot-high chain link fence in a selected location. The total first cost of the plan is estimated at $19.4 million. Annual benefits are estimated at $2.9 million, and the annual costs are estimated at $1.7 million, with a benefit-to-cost ratio of 1.71. POSITIVE IMPACTS: Property values would increase where the flooding problem is reduced in the upper two thirds of the stream. With the preferred alternative in place, 452 units would no longer be flooded by the 10-year flood and 880 units would no longer be flooded by the 100-year flood. The flood forecasting and warning system would allow people more time to move property from areas that would be flooded. After completion, the new channel would decrease the amount of erosion presently occurring in the project area. Approximately 69.6 acres of undeveloped open land are likely to be developed because of decreased flooding. Planting of vegetation adjacent to the hiking trail would reduce adverse aesthetic impacts. NEGATIVE IMPACTS: In the lower part of the creek, some property values would decline because of induced flooding. The new channels would be approximately 46.5 acres larger than the old channel, with an additional 24.3 acres cleared for rights-of-way. Disposal areas would cover 57.6 acres of crops, 81.4 acres of open land, and 9.8 acres of forest and brush. Approximately 10.0 miles of streams would be adversely impacted by the channelization. The most significant impact on the terrestrial ecosystems would be the loss of 10.0 miles (70.8 acres) of riparian vegetation.

Preparation date: December 10, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED WOLF CREEK VALLEY SKI AREA, SAN JUAN NATIONAL FOREST, MINERAL COUNTY, COLORADO. AN - 36387217; 1161 AB - PURPOSE: Development of a downhill ski area, located approximately 12 miles north of Pagosa Springs, Colorado on U.S. Highway 160 in the area commonly known as Windy Pass in the Pagosa District, San Juan National Forest, Mineral County, Colorado, has been proposed by Westfork Investment, Ltd. Under the preferred alternative, development would be phased, with the first phase having a capacity of 4,050 skiers at one time, four lifts, and 253 acres of trails. Future phases would be completed as the market may justify. At project completion, the ski area would have a capacity of 11,750 skiers at one time, 14 chairlifts, a gondola, and 904 acres of trails. Approximately 2,700 acres of National Forest System land would be under permit. An area included in the proposal and of particular importance to the proponent is that referred to as "the back bowls." Four lift systems are proposed to service this terrain, which is in an open bowl configuration with natural parks and openings and glades of aspen intermixed with spruce fir. Ability levels serviced by the proposed lifts range from low intermediate to expert. The four back bowl lifts would operate at a relatively low hourly capacity in order to maintain a low-trail density of five skiers per acre. A capacity of 1,750 skiers at one time is proposed in an effort to assure a quality skiing experience. The ski base area would be located on private land immediately adjacent to the base lift terminals and ski runs. The ski base would contain skiing-oriented services, a base lodge, transit facilities, and skier parking in a combination of surface parking lots and parking structures. To accommodate this base, approximately one mile of U.S. Highway 160 would be relocated 550 feet west of the current alignment. The proposed relocation would be designed to meet the requirements of a Type B roadway with a design speed of 65 mph, with two 12-foot lanes and 8-foot paved shoulders on each side. Where auxiliary climbing lanes are necessary, they would be 12 feet wide and the shoulder would be reduced to 4 feet. The estimated cost of the proposed road realignment would be $2.8 million and would be borne wholly by the proponent. A full range of housing units and services would be developed in the ski base area and ultimately would include 20 single-family residences, 78 townhouses, 476 condominiums, and 220 condominium-hotel units. In addition, approximately 65,000 square feet of ski-related commercial retail space would be built at the ski base. Two 18-hole golf courses, an equestrian center, a trail system, and water-oriented recreation uses would be included in the program. Development of "the back bowls" area would be postponed until an operations and mitigation plan is developed. POSITIVE IMPACTS: Within the total area proposed for development, significant cultural resources would be preserved. Because of the high value of vegetation to the development, the danger of wildfire spreading on-site would be reduced. In some cases, there would be an opportunity for improving certain wildlife habitats. Development would enhance and help diversify the economic base of the area, would increase employment opportunities, would help meet projected demand trends for downhill skiing, and would increase the use of the San Juan National Forest. Water quantities are anticipated to increase due to tree cutting for ski trails and the nature of snowfall as affected by wind circulation, which would result in earlier snowmelt runoff. NEGATIVE IMPACTS: Development of the ski area would be phased, and the first steep trails cleared would have a relatively high risk of natural and construction-induced slope failures, with increased debris flows from landslides and ski trail construction. There would be less visual diversity and character, especially in the fall, because of the removal of some aspen trees. An estimated 28 percent of the total timber/vegetation types on public land would be impacted. Vegetation disturbance would affect wildlife habitat over the entire proposed permit area. The realignment of U.S. Highway 160 would have a short-term impact due to land disturbance resulting from construction. A proposed lift could affect one archaeological site on National Forest System land. Noise levels would increase as a result of increased traffic and operation of the ski area (lifts, slope maintenance vehicles, snowmaking, etc.).

This is the largest metropolitan area in Alabama with a population of approximately 400,000. Flooding within the basin has been a problem for many years, but changes within the drainage area and modifications to the channel have tended to intensify the problem. The two largest floods of record for Village Creek occurred in March 1970 and December 1983. The 1970 flood is considered to be about the 100-year flood event, while the 1983 flood is about a 30-year flood event.

In the Baltimore District, flood damage reduction surveys are conducted for businesses and industries to provide advice on self-help actions to reduce flood losses. Surveys are conducted by an interagency team of representatives from various federal, state, and regional agencies. Collectively, the team possesses expertise in a full range of flood damage reduction measures including structural and nonstructural improvements, floodproofing, emergency preparedness, evacuation, flood warning, and flood insurance. Since 1979, thirty-one surveys have been conducted for various types of facilities including metal and textile product manufacturers, a food processing plant, aircraft manufacturing and repair facilities, industrial parks, a multi-tenant shopping center, and wastewater treatment plants. In every case, the team recommended some form of action relating to flood warning and emergency response. To varying degrees, these recommendations have been implemented and proven to be successful. This paper will examine some of the typical flood warning-response actions recommended and will review the results of several follow-up activities to determine the degree of implementation and effectiveness of these actions. The author will also comment as to the conditions which have influenced the degree of implementation and success of such actions.

This effort has created a need for cooperation and coordination between the various federal agencies concerned with the action. In response to this need a LFW&RS work group was established as a way to further communications among participates. The work group has meet periodically and is a gathering of representatives from federal agencies plus other invited non-federal individuals. The get togethers serve common agency interests and has provided a forum for discussion, shared work efforts and agreements. The work group has caused a synergism of shared effort that produced a well received publication and other initiatives not achievable within a single agency or individual. At present the group is actively engaged in "getting the word out" to interested individuals or communities. So far I have given you a brief overview of why the group was formed, who the members are, what it has accomplished, and where it is going. In my remaining time I will provide a broader depth of why, who, what, and where but organise the presentation into three topic areas of background, history and present direction of the LFW&RS work group.

Many communities are beginning to rely on flood warning and preparedness as the major remedy for their flood hazard problems. It is an adjustment that is inexpensive, innocuous, and does not preclude other damage alleviation measures. Gilbert White recognized this back in 1939, as seen in the following statement, "Flood-forecasting is essential to the successful operation of most storage-reservoirs and a few protective works such as the fuse-plug levees in the Lower Mississippi flood-protection plan. It is basic in any plan for emergency-evacuation. It is highly desireable in conjunction with programs for readjustment of structures or land use. Flood-loss insurance demands effective forecasting. Complete evacuation alone among the lines of action does not include it." This paper focuses on the relatively recent events that have broadened the Corps of Engineers role in flood warning and preparedness. It is fairly recently that the Corps has taken a leading role in the planning and design of community flood warning and preparedness systems. This paper describes 1) the extent of this new capacity, 2) the reasons for the new scope of responsibility, 3) the impediments that limit the extent of the Corps' involvement, and finally, 4) a framework is proposed for institutionalizing and enhancing these functions.

AN - 36399522; 1154 AB - PURPOSE: Expansion and reinforcement of the Pacific Northwest-Pacific Southwest (PNW-PSW) Intertie by electrical transmission projects of public and privately owned utilities are proposed in California, Oregon, and Washington. The projects have multiple purposes and would essentially provide a third 500 kilovolt (kV) alternating current (AC) transmission path between southern Oregon and central California (California-Oregon Transmission Project (COTP)); complete a third 500 kV AC transmission path in the San Joaquin Valley of California (Los Banos-Gates Transmission Project); and reinforce the existing 500 kV AC transmission system facilities in Oregon and southern Washington (Pacific Northwest (PNW) Reinforcement Project). The Transmission Agency of Northern California, Western Area Power Administration, and privately owned utilities and additional public entities propose to build an approximately 340-mile-long 500 kV AC transmission line from southern Oregon to the Tesla Substation in central California for the COTP. The project would include a new substation near either Malin, Pinehurst, or Keno, Oregon; approximately 140 miles of new 500 kV transmission line from southern Oregon to a new substation near Redding, California; approximately 170 miles of reconstructed 230 kV to 500 kV transmission line owned by the Western Area Power Administration from the new Redding area substation to the Sacramento River; approximately 20 miles of new 500 kV transmission line from the Sacramento River to the existing Tracy substation; a new series compensation station near Maxwell, California; expansion of the Tracy substation; and approximately six miles of new 500 kV transmission line between the Tracy substation and the existing Tesla substation. For the Los Banos-Gates Transmission Project, the Pacific Gas and Electric Company proposes to build an approximately 84-mile-long 500 kV transmission line in the foothills of western San Joaquin Valley between the existing Los Banos and Gates substations. The Los Banos-Gates Transmission Project includes approximately 84 miles of new 500 kV transmission line; realignment of the existing Los Banos-Midway No. 2 500 kV transmission line into Gates substation; modification of the Los Banos and Gates substations to accommodate new equipment and line connections; installation of shunt capacitors at various existing substations; possible installation of series capacitors at Gates and/or Midway substations; and restructuring portions of the Gates-Arco-Midway 230 kV transmission line. For the PNW Reinforcement Project, the Bonneville Power Administration, Pacific Power and Light Company, and Portland General Electric Company propose to build new and to modify existing transmission lines and supporting facilities in southern Washington and Oregon. Approximately eight miles of new 500 kV transmission line are proposed. Modifications may be made to 13 or more existing substations. One new substation may be constructed between the existing Marion and Alvey substations. POSITIVE IMPACTS: The proposed actions would expand the bidirectional capability of the PNW-PSW Intertie transmission system and would help serve California's need for economical power, the PNW's desire to sell surplus power, and the need for maintaining and increasing the reliability of the existing transmission system. The COTP would add approximately 1,600 megawatts (MW) of additional transfer capability between the PNW and California. The projects would also add to and strengthen the existing high voltage transmission links between California and the PNW, would provide for greater access to northwest power surpluses, would facilitate more efficient use of regional power resources, would provide greater resource diversity, and would enhance transmission system reliability. NEGATIVE IMPACTS: For the COTP, potential effects include excessive wind and water erosion. Wildlife effects include the possibility of collision of special-status and sensitive bird species or waterfowl with conductors and shield wires. Land use impacts include crossing prime timberland, prime farmland, and agricultural preserves. Visual effects would be reduced, but would remain significant following application of mitigation measures. Potential socioeconomic effects include inadequate temporary housing facilities for construction workers, reduced agricultural production, construction of new access roads, and location of transmission lines within areas close to residential communities. The Los Banos-Gates Project would result in only minimal impacts to earth resources, air and water quality, and public health and safety. The primary short-term impacts include disturbance of approximately 260 acres of land due to construction activities. Long-term operational impacts include a maximum loss of approximately 150 acres of land to access roads and tower foundations and a change in aesthetic quality due to the presence of towers in certain viewsheds. For the PNW Reinforcement Project, additional land would be required to accommodate some of the new equipment. New rights-of-way would have to be acquired for approximately eight miles of new transmission line.

AN - 36397986; 1190 AB - PURPOSE: Flood protection measures were proposed for the city of Salmon and nearby rural areas along the Salmon River in Lemhi County, Idaho. These areas periodically experience flooding related to spring runoff and formation of ice jams in the Salmon River. Several alternatives were investigated to reduce ice jam floods and resulting damage to private, commercial, and public property. Of the many alternatives, including options, initially considered, four were studied in detail. These were the Dump Creek/Deadwater Channelization, which involves Salmon River channel alterations in the wild and scenic river approximately 26 miles downstream of the city of Salmon; the Lemhi River Levee, which involves extension and improvement of the existing Lemhi River levee at the city of Salmon; the permanent evacuation of the Lemhi River floodplain, which would remove the most susceptible structures from floodprone areas; and a combination of levees and permanent evacuation of the Lemhi River in Salmon. Although any of the four alternatives are feasible from an engineering and economic standpoint, none meets all of the criteria for a federal flood control project. Therefore, "no action" has been recommended. POSITIVE IMPACTS: Emphasis has been placed on maintaining existing conditions, particularly as related to the Salmon River. Most concerns focused on fish, wildlife, wetlands, and wild and scenic designation of the river. NEGATIVE IMPACTS: Flooding from both ice jams and spring runoff would continue, as would flood fighting and temporary evacuation during these floods.

AN - 36405072; 1102 AB - PURPOSE: Enlargement of the existing 40-foot-deep channel approaches in the Mississippi River and the Southwest Pass that provide access to the ports of New Orleans and Baton Rouge, Louisiana is proposed. The project would involve enlargement of the 40-foot channel in Southwest Pass from Head of Passes to the 55-foot contour in the Gulf of Mexico and the 40-foot channel in the Mississippi River between the Head of Passes (river mile 0) and the Port of Baton Rouge (river mile 233) to a depth of 55 feet, and enlargement of the 35-foot channel along the left descending bank of the Mississippi River in New Orleans Harbor between river miles 86.7 and 104.5 to a depth of 40 feet. This Supplemental Information Report relates to the proposed construction of a test sill as part of the advanced planning work for the Mississippi River Ship Channel-Gulf to Baton Rouge (Deep-Draft) project. This test sill or underwater barrier would be constructed across the bottom of the Mississippi River navigational channel at mile 47.4. Material dredged from a borrow area, approximately four miles upstream, would be used to construct the sill. The crown of the sill would be at an elevation of approximately -55 feet National Geodetic Vertical Datum. The sill would not be maintained but would be monitored for three to four months to determine how effectively it halts the advance of the saltwater wedge during low-river flows. POSITIVE IMPACTS: Enlargement of the channel would constitute the most efficient means of opening the river ports to oceangoing commerce. Annual benefits in excess of costs would amount to $1.2 billion. Valuable wetland and upland habitat would be created by overbank disposal of dredged material. In the proposed Deep-Draft project, the sill is a mitigation measure. The test sill has been designed to inhibit the upriver movement of the salt wedge. As such it will minimize the impacts caused by saltwater intrusion on the municipal intakes upstream of the sill. Eddying currents may create a favorable feeding habitat for fish and other aquatic organisms. NEGATIVE IMPACTS: Fisheries and several sea bird nesting colonies would be damaged by overbank disposal of dredged material and by disposal of dredged material in estuarine water bodies and Gulf waters. Deepening of the 40-foot channel in Southwest Pass and the Mississippi River would cause an increase in the frequency of saltwater intrusion up the Mississippi River, rendering water in the lower reaches unsuitable for municipal use during periods of low flows. Dredging activities could damage historic shipwrecks, degrade water quality in localized areas periodically, and interfere with recreational activities on the river and on associated land. The elevation and bottom contours of the Mississippi River channel at mile 47.4 would be significantly altered by construction of the sill. Very minor changes to substrate composition might be expected to result from the disposal of dredged material for sill construction. Significant movement of a portion of the dredged material is expected immediately following disposal. Benthic populations inhabiting the main river channel within approximately 2,000 feet downstream of the discharge points would be killed by direct burial.

This Supplemental Information Report relates to the proposed dredging of a test crossing at mile 116 of the Mississippi River, as part of advanced planning work for the Mississippi River Enlargement (Deep-Draft) project. This test crossing would be dredged so that the rate of shoaling could be monitored. Recent hydrographic surveys have revealed that the test crossing must be dredged two feet deeper than previously planned. These additional two feet of dredging are required in order to create a better defined channel that would enhance the monitoring of shoaling rates. POSITIVE IMPACTS: Enlargement of the channel would constitute the most efficient means of opening the river ports to oceangoing commerce. Annual benefits in excess of costs would amount to $1.2 billion. Valuable wetland and upland habitat would be created by overbank disposal of dredged material.

Dredging activities could damage historic shipwrecks, degrade water quality in localized areas periodically, and interfere with recreational activities on the river and on associated land. Thousands of cubic yards of dredged sediment would be expected to remain in suspension following disposal and would be transported downstream with the spring suspended solids load out to the Gulf. A reduction in water clarity downstream of the disposal areas is expected.

This Supplemental Information Report addresses project features between Venice, Louisiana and the Gulf of Mexico. The existing channel would be enlarged to a 55- by 750-foot channel from Venice, mile 10.5 Above Head of Passes to mile 17.8 Below Head of Passes (BHP) in Southwest Pass. From miles 17.8 to 22.1 BHP, the existing channel would be enlarged to 55 by 600 feet. Most material excavated for construction and maintenance of the channel between Venice and mile 18.8 BHP would be deposited along either side of the river. All material between mile 18.8 BHP and the Gulf would be removed by hopper dredge, with 70 percent of the material being deposited into a designated ocean dumping site west of the channel and 30 percent of the material being agitated into suspension by the hopper dredge.

AN - 36397477; 1103 AB - PURPOSE: Enlargement of the existing 40-foot-deep channel approaches in the Mississippi River and the Southwest Pass that provide access to the ports of New Orleans and Baton Rouge, Louisiana is proposed. The project would involve enlargement of the 40-foot channel in Southwest Pass from Head of Passes to the 55-foot contour in the Gulf of Mexico and the 40-foot channel in the Mississippi River between the Head of Passes (river mile 0) and the Port of Baton Rouge (river mile 233) to a depth of 55 feet, and enlargement of the 35-foot channel along the left descending bank of the Mississippi River in New Orleans Harbor between river miles 86.7 and 104.5 to a depth of 40 feet. This Supplemental Information Report involves construction of a submarine barrier or sill across the bottom of the Mississippi River at mile 64.1 Above Head of Passes to mitigate the effects of increased saltwater intrusion on municipal and industrial river water supplies. The proposed measure involves the construction of a submarine barrier or sill across the bottom of the river using sediment dredged from nearby upstream borrow areas in the river. POSITIVE IMPACTS: Enlargement of the channel would constitute the most efficient means of opening the river ports to oceangoing commerce. Valuable wetland and upland habitat would be created by overbank disposal of dredged material. Saltwater intrusion would be significantly affected by sill construction. The sill would slow the upstream movement of the saltwater wedge to a point that durations of intrusion would be less than under current conditions. Eddying currents might create a favorable feeding habitat for fish and other aquatic organisms where none existed before. NEGATIVE IMPACTS: Fisheries and several sea bird nesting colonies would be damaged by overbank disposal of dredged material and by disposal of dredged material in estuarine water bodies and Gulf waters. Dredging activities could damage historic shipwrecks, degrade water quality in localized areas periodically, and interfere with recreational activities on the river and on associated land. Since the sill would erode completely during winter flow levels, it would require rebuilding each year when unusually low water is threatened. Based on historical data and elaborate model analyses, it is estimated that construction would be required once every five years, on the average, to halt saltwater intrusion at existing frequencies. Benthic populations, mainly Asiatic clams, inhabiting the main river channel within approximately 2,000 feet downstream of the discharge points would be killed by direct burial.

AN - 36401089; 1088 AB - PURPOSE: Extending Warren Road from its present terminus at Maryland Route 45 (York Road) to I-83 (the Harrisburg Expressway) in Cockeysville, Baltimore County, Maryland is proposed. Projected phased construction of the road would be from 1988 to 1992. Five specific alignments and five interchange configurations have been studied along the general corridor. Two general approaches are being considered. The first would extend Warren Road due west to I-83 with a new interchange constructed just south of Beaver Dam Run. Between York Road and Beaver Dam Road, the new road would consist of a closed-section (curbed), 5-lane roadway that would cross two properties: the Baltimore Gas and Electric Company's Cockeysville Service Center and Baltimore County's Texas Landfill, which is filled and closed. Between Beaver Dam Road and I-83, the roadway would be an open-section (graded shoulders without curbs), 4-lane road with a 34-foot median. This section crosses the northern end of Genstar Stone Product Company's Texas Quarry. The interchange ramps would be constructed on undeveloped wooded property and farmland, as well as on Genstar property. The second general approach involves extending Warren Road only as far as Beaver Dam Road and constructing an interchange where that road now crosses I-83. The existing Beaver Dam Road is wide enough for four lanes and would connect Warren Road Extended to the new interchange. The only improvements necessary along Beaver Dam Road would be additional lanes at the intersection with McCormick Road. The interchange would include ramps to and from the south only, because of the proximity of this interchange to Shawan Road; northern traffic movements would use Shawan Road. Total costs range from $12 million to $42 million, depending on the alignment and configuration chosen. POSITIVE IMPACTS: The extension of Warren Road and a new interchange at I-83 are needed to relieve traffic congestion along York Road and on Padonia and Shawan roads. The extension of Warren Road is expected to draw traffic off York Road and to relieve the present congestion. The extension would also provide an alternative route to I-83 and would relieve rush hour congestion on I-83 in the area of Warren Road. NEGATIVE IMPACTS: The number of properties affected ranges from 19 to 28, with the total required rights-of-way ranging from 24.0 to 116.6 acres. Depending on the alignment and the interchange options selected, 3.4 to 21.7 acres of floodplain and 1.7 to 9.2 acres of wetlands would be affected. As many as eight historical sites could be involved.

AN - 36397631; 1097 AB - PURPOSE: Designation of the Brunswick, Georgia Ocean Dredged Material Disposal Site is proposed. Each year the entrance channel to Brunswick Harbor must be dredged because natural processes cause it to shoal. Approximately 0.6 million yards of sediment are dredged annually from the entrance channel and dumped in the Brunswick ocean disposal site. Material is dredged, transported by hopper dredge, and discharged from underwater ports while the hopper dredge is underway and within the boundaries of the disposed site. The existing site has been used since 1964. The EPA interim-approved site at Brunswick is rectangular in shape and is approximately six nautical miles southeast of Brunswick, Georgia in 30 feet of water. The site is proposed to receive final designation for the disposal of dredged material. The disposal operations would be regulated to prevent unacceptable environmental degradation outside of site boundaries. POSITIVE IMPACTS: Brunswick is one of two major ports of Georgia and, consequently, maintenance of this port for navigation is vital to the economy of the South Atlantic United States. NEGATIVE IMPACTS: Adverse environmental effects of the proposed action include mounding, smothering of the benthos, and possible habitat alteration.

AN - 36400026; 1070 AB - PURPOSE: Potential hydropower development in the Lehigh River Basin, Pennsylvania was evaluated in response to congressional authorization. It was concluded that the optimum hydropower development at the modified Francis E. Walter Reservoir would be a 17.3 megawatt conventional peaking project utilizing up to four inches of reservoir storage for daily pondage. A reregulating reservoir, with 463 acre-feet of storage, would be added immediately downstream of the Walter Dam to minimize downstream aquatic impacts. The peaking plant would consist of a single, horizontal shaft Francis-type turbine. While this plant would operate on the flows that would normally pass through the reservoir daily, the daily flow would be compressed into a 1,400 cubic feet per second turbine discharge. During nongenerating periods, water would be stored behind the main reservoir. Flows would be stored overnight for release during a four-hour period the next day. This release would then be held behind a new smaller dam downstream for gradual release. This plan would have a first cost of $28.7 million, average annual benefits of $3.98 million, and a benefit to cost ratio of 1.3. POSITIVE IMPACTS: The hydroelectric power generated would reduce the consumption of fossil fuels. Additional recreational facilities are planned as part of the dam modification, to include picnic areas, trails, boat launch sites, fishing, nature areas, and sports fields, among others. NEGATIVE IMPACTS: The sole area of specific concern that has been expressed involves the effect of the project on downstream fishery resources. The varying releases from the plant would stress the stream ecosystem and would reduce the aquatic resources both in numbers and species diversity. While the reregulation reservoir would eliminate the fluctuating releases, it would replace a 5,000-foot portion of the free-flowing Lehigh River with an impoundment that fluctuates 30 feet daily. Approximately 5 acres of disturbed area and some 20 acres of forested, generally steep shoreline, would be inundated by the reregulation reservoir. Approximately 20 acres of aquatic and 25 acres of terrestrial habitat would be effectively eliminated as productive ecosystems.

AN - 36400275; 1091 AB - PURPOSE: Widening of Marine Drive and realigning the roadway connection between Interstate 5 (I-5) and the Rivergate Industrial District (RID) in Multnomah County, Portland, Oregon are proposed. The Northern Build Alternative would provide a 1.3-mile connection between I-5 and the RID. It would consist of two separate design sections, the first from I-5 to the railroad structure (cross-levee) and the second from the structure to a connection with Marine Drive in Rivergate. Each design would provide four travel lanes, a bicycle facility, and some level of pedestrian facilities. The first, or eastern segment, would include a center turn lane, a sidewalk on the south side of the roadway, and a separated bicycle facility. The western segment would not include the median lane and would be modified to include 6-foot bicycle lanes and 5-foot sidewalks on both sides of the roadway. The existing underpass through the railroad structure would accommodate the two westbound traffic lanes and the 10-foot bicycle path. A new underpass would be constructed south of the existing trestle, to accommodate the eastbound travel lanes and a sidewalk. The intersection of Marine Drive and North Portland Road would be redesigned and signalized. The North Force Avenue intersection may require signalization as traffic volumes increase. The Southern Build Alternative would begin with a modified I-5 interchange, south of its present location. The design would consist of four travel lanes, a median turn lane, 6-foot bicycle lanes adjacent to the outside travel lanes, 5-foot sidewalks, and a 4-foot landscaped area next to the sidewalks. Structures would be required to cross under the three sets of railroad tracks intersected by the alignment. The intersection with North Portland Road would be signalized, and the feasibility of signalizing North Force Avenue would be studied. Preliminary estimates of costs are $20.9 million for the Northern Alternative and $19.5 million to $23.5 million for the Southern Alternative. POSITIVE IMPACTS: The Marine Drive project would improve the connection between I-5 and the RID and would provide an acceptable level of traffic service for the planned development and growth expected in the project area. This development may generate increased employment and tax revenues. The Northern Alternative would provide access to view the Oregon slough area. NEGATIVE IMPACTS: The Northern Alternative would result in the displacement of several existing businesses. Two residential (houseboat) moorages would be impacted by the proximity of the roadway. The development of water-based activities could be restricted by the alignment. The Southern Alternative would have direct and secondary impacts to wetlands. Its proximity would potentially disturb an active Great Blue Heron rookery. The alignment would be directly adjacent to an active recreational area. Noise levels would exceed criteria at several locations. LEGAL MANDATES: Executive Order 11990 and Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (42 U.S.C. 4601).

Preparation date: November 17, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MODERNIZATION AND EXPANSION OF LOGISTIC SUPPORT SYSTEMS, NAVAL WEAPONS STATION EARLE, COLTS NECK, NEW JERSEY (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF FEBRUARY 1980 AND THE COMPANION TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1986 FILED BY THE DEPARTMENT OF THE ARMY, CORPS OF ENGINEERS). AN - 36386145; 1061 AB - PURPOSE: This report represents the final supplement to the final environmental impact statement (EIS) issued in 1980 by the Department of the Navy and adopted in 1986 by the Army Corps of Engineers for the Modernization and Expansion of the Logistic Support System (MELSS) at Naval Weapons Station (NWS) Earle in Colts Neck, Monmouth County, New Jersey. This would involve relocation of two Auxiliary Oil and Explosive ships (AOEs) from Naval Station Norfolk, Virginia to NWS Earle in New Jersey. Since the draft supplemental EIS was released in June 1986, several notable decisions have been made and actions taken, including the following: (1) The fuel storage facility portion of the Ship Fuel Replenishment System (SFRS) has been given a no-action status. The selection of a land-based site has been deferred while the Navy conducts a thorough alternatives analysis. In the meantime, the AOEs will be refueled while underway or at Craney Island in Norfolk, Virginia. (2) Because of concern over the safety of residents living in close proximity to the SFRS facilities, a risk analysis was conducted for the oil-water separation system, which showed that a catastrophic event resulting in residential impact was not reasonably foreseeable for the life of the facility. A similar study will be conducted when the site has been selected. (3) There is currently no preferred disposal alternative for the dredged sands, and three alternatives are being considered: beach nourishment on Sandy Hook, as originally proposed; beach nourishment along the seawall in Sea Bright and Monmouth Beach; and final capping of the northwest sector of the Mud Dump. In order to mitigate the loss of bay-bottom habitat during dredging operations, the Navigational Prohibited Zone was opened to clammers during September 1986. This practice will not be repeated when the AOEs are homeported because there will always be one ship at dock requiring security of the surrounding area. Materials will be dredged by clamshell or hydraulic dredge. Dredging will be in the area of the new pier and turning basin, which contains the siltiest materials. The sandier materials from the terminal channel will be dredged last to provide cover or a "cap" on the silty materials when placed at the Mud Dump. POSITIVE IMPACTS: The proposed action would provide an efficient homeport facility with a high degree of military readiness. Explosive and navigation safety would improve, reducing the risk of accidents and oil spills. In the long term, an increase in recreational benefits is expected. Habitat for beach nesters, including the piping plover and least tern, would be increased. The increase in hard substrate resulting from the new pilings would have long-term beneficial impacts for sessile organisms and for fish as a result of increased intra-pier habitat. Compton's Creek navigation channel would not be encumbered by the Explosive Safety Quality Distance arc. NEGATIVE IMPACTS: Pier construction would result in the destruction of the benthic habitat and organisms located at each piling site. Short-term impacts include the degradation of local air quality and an increase in noise levels during construction. An increased navigation restricted area around the pier would have a minor impact on water-related recreational uses. The increased navigation restricted area would reduce the general anchorage area of Sandy Hook Bay by 1.5 percent.

Preparation date: November 14, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CARRIER BATTLE GROUP (CVBG) HOMEPORTING IN THE PUGET SOUND AREA, WASHINGTON (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1986). AN - 36397856; 1062 AB - PURPOSE: This supplement was prepared because the Corps of Engineers determined that additional information was necessary before a decision could be made on the Department of the Navy's permit application to construct homeport facilities for a carrier battle group (CVBG) at the Norton Avenue Terminal in Everett, Washington. In order to supplement the Navy's final environmental impact statement (EIS), it was necessary that the Corps of Engineers officially adopt that EIS, which was accomplished (see 86-0267F). The purpose of this final supplement is to provide information on the homeport project and on dredge disposal sites and methods. Approximately 3.3 million cubic yards of sediment would have to be removed. Contaminated surface sediments would be removed by a clamshell dredge; clean sediment would be removed with a hydraulic dredge or clamshell dredge and deposited using either a pipeline with diffuser or pumpout barge. Based on Dungeness crab data provided by the University of Washington, a new preferred dredge spoil disposal alternative has been developed. The preferred disposal site, a deepwater confined aquatic disposal (CAD) site, is located at a depth to minimize impact to these resources. The contaminated sediments would be "capped" with clean sediments. POSITIVE IMPACTS: Development of a new homeport facility would be in keeping with the Navy's plan to expand to 600-ship service and with the policy of decentralizing future naval forces. The Puget Sound area would provide an established naval support complex with protected deep waterways, plus existing industrial, commercial, and transportation networks. During the project construction period (1987 to 1990), a maximum of 1,000 jobs would be available. Actual operation of the homeport would generate approximately 16,000 direct and indirect jobs in the Everett/Snohomish County area. NEGATIVE IMPACTS: Approximately 2.5 million cubic yards of bottom materials would be removed from the site. The associated dredging activities could affect water quality, damage marine habitats, and result in temporary loss of sessile and motile organisms. Significant population growth in Snohomish County would require the construction of 8,600 new housing units and would place demands on county services. Since the major commissary and exchange, as well as some other facilities, would be located at the Sand Point Station near Seattle, population growth impacts would be distributed toward Seattle.

AN - 36397685; 1100 AB - PURPOSE: Levee and channel improvements with pumping facilities for localized drainage near the Saylor Street crossing on the Agana River in Guam are proposed. This final supplement to the final environmental impact statement was prepared to address proposed changes in plans for flood control improvements at the Agana River, Guam. The preferred alternative would include a 1,700-foot floodwall and an 850-foot levee on the left side of the Agana River; 1,300 feet of concrete channel improvements between Agana Bay and upstream of Saylor Street; and 410 feet of riprap and unlined outlet channel to the ocean. The Marine Drive Bridge invert would be excavated to -4 feet mean sea level (msl), and the Saylor Street Bridge would be replaced. Interior damage requirements include an 850-foot-long storm drain on the left bank and various interior drainage culverts. The project would provide 100-year flood protection for Agana. The estimated first cost of the preferred alternative would be $4.9 million, of which $3.7 million would be borne by the Federal Government. Based on estimated annual benefits of $639,000 and estimated average annual costs of $454,000, including annual operation, maintenance, and replacement costs, the benefit-to-cost ratio would be 1.4. POSITIVE IMPACTS: The preferred alternative would encourage community growth and business activity in protected portions of the 100-year floodplain. The project would stabilize the basin and promote orderly future development. With flood protection, Agana Central Park would have the potential of becoming a major recreation-sports complex. Project control would decrease the potential for discharge of toxic materials from urban and commercial developments adjacent to the stream and marsh. NEGATIVE IMPACTS: Construction noise, dust, and air pollution may temporarily disturb residents and visitors to the Agana area. Approximately 0.4 acres of wetland habitat would be lost by construction of the floodwall. Approximately 0.5 acre of estuarine habitat would be displaced by the riprap-lined channel, and the concrete flood control channel would displace 1,300 linear feet of riverine and estuarine habitat.

AN - 36394213; 1093 AB - PURPOSE: Construction of the fully access-controlled Woonsocket Industrial Highway/Route 99, located in the towns of Lincoln, North Smithfield, Woonsocket, and Cumberland, Rhode Island, beginning near the interchange of I-295 and proceeding north to the Route 146 /Route 146A merge and connecting to Route 122 (Mendon Road) is proposed. The final supplement evaluates the impacts and addresses wetlands and water quality concerns associated with three alternative alignments. The alternatives considered include construction of a four-lane limited-access roadway along three alternative alignments. All of the alternatives involve a transportation network linking the Route 146/I-295 interchange to Route 122 (Mendon Road) in the vicinity of the Woonsocket /Cumberland town line. The three limited-access alignments are Alignments 2, 3, and 4B; they are 4.2, 3.6, and 3.3 miles long, respectively. Alignments 2 and 3 originate at the Route 146/I-295 interchange and proceed north along existing Route 146. Alternative 4B originates from Route 146 immediately north of the I-295 interchange and parallels Crookfall Brook. All alignments provide for a four-lane divided roadway facility with variations, due to frontage road design and median widths. All alignments have been designed to operate at acceptable levels of service. Roadway construction costs (excluding rights-of-way) have been calculated to be $40.9 million, $42.4 million, and $36.0 million, respectively. POSITIVE IMPACTS: Implementation of the project would result in significant improvements to the transportation network and would stimulate economic growth in this area of the state. NEGATIVE IMPACTS: The following displacements associated with the three alignments would result. Alignment 2: 33 residential and 17 commercial; Alignment 3: 27 residential and 17 commercial; and Alignment 4B: no displacements. The proposed projects would affect 12.3 acres of wetlands for Alignment 2, 4.1 acres for Alignment 3, and 7.2 acres for Alignment 4B. Implementation of Alignments 2 and 3 would create adverse impacts to the North Smithfield commercial areas along Route 146. Alignment 2 would have an adverse effect on the Blackstone Canal Historic District; Alignment 3 would have an adverse effect on the Smithfield Road Historic District and the Blackstone Canal Historic District; and Alignment 4B would have an indirect adverse visual effect on the Blackstone Canal Historic District.

Preparation date: October 31, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PARKER LAKE, MUDDY BOGGY CREEK, OKLAHOMA (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF APRIL 1981). AN - 36386980; 1105 AB - PURPOSE: The construction of an earth embankment, a gated conduit for flood releases, a limited service spillway, access roads, and project buildings at the Parker Lake Damsite, Muddy Boggy Creek, located in Oklahoma, is proposed. The project would provide for flood control water supply and recreation activities. The embankment would be 2,100 feet long and have a maximum height above the streambed of approximately 100 feet. It would have a base width of 425 feet and crest width of 30 feet. The 100-foot-wide limited-service spillway would be located on the right abutment. This spillway would be needed for floods greater than the standard project flood and would be protected by one foot of topsoil and vegetation. The outlet works would consist of a gated intake tower, a 12-foot-diameter cut-and-cover conduit, a stilling basin, a 54-inch low-flow pipe, and a 54-inch water supply conduit. Approximately 1,050 acres of land, in addition to the 13,800 acres of land associated with the dam and reservoir, would be purchased and managed for mitigation of wildlife losses, and 3,200 acres of land above the conservation pool would be managed for the same purpose. An additional 500 acres of land would be purchased for future cost-sharing of recreational development. Estimated cost of the project is $12.1 million, and the benefit-cost ratio is estimated at 1.1. This supplemental report updates the final environmental impact statement (FEIS) of April 1981 by evaluating the effects of dredged and fill material. Construction of the embankment would result in the loss of approximately 20 acres of aquatic and terrestrial substrate. Replacing this substrate would be a structure composed of up to 3.4 million cubic yards of impervious and random materials, one side of which would be covered by limestone riprap (size yet undetermined) and the other by vegetation. Upstream substrate would be significantly affected by the establishment of 61 borrow pits for the excavation of construction materials. All borrow sites would be inundated following completion of the project. POSITIVE IMPACTS: The lake would reduce annual flood damages, provide a dependable water supply of 42 million gallons per day, and initially satisfy the needs of 90,000 recreationists. Completion of the project would result in the regulation and control of streamflow extremes. Downstream flooding would be essentially eliminated, and water-level fluctuations would become less variable and more predictable. Home development, industrial development, and retail sales should increase. NEGATIVE IMPACTS: Approximately 6,110 acres of land would be inundated for the conservation pool and an additional 3,510 acres would be flooded for the flood control pool. Inundation would destroy terrestrial wildlife habitat, reduce agricultural productivity, and limit development of mineral resources. Seven residences would be relocated. Water impoundment would result in a net water evaporation of 7,000 acre-feet annually. The water loss would cause the concentration of inorganic salts and nutrients in the lake, with a net concentrating effect of up to 10 percent annually. Creation of the lake would eliminate lowland pasture, forest, and stream-oriented recreation in the project area. Eight of 24 archaeological sites in the project area would be permanently inundated, and 4 others would be subject to shoreline erosion from wave action, flood pool operations, and land-use changes. Power and telephone lines in the area would be relocated or removed; several roads would be relocated or abandoned; and three cemeteries would be relocated. A major impact on water circulation would be the potential for thermal stratification of impounded waters. Increases in stream turbidity would occur during construction. Secondary aquatic ecosystem effects include water-level fluctuation effects and the influence of changes in downstream land-use patterns. Fluctuating lake levels characteristic of reservoirs could affect the establishment and success of littoral aquatic vegetation and influence the spawning success of fish species.

Preparation date: October 29, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HIGHWAY IMPROVEMENT PROJECT FOR STATE ROUTE NUMBER 1, NEAR CARMEL, FROM 0.3 MILE SOUTH OF THE CARMEL RIVER TO THE PACIFIC GROVE INTERCHANGE (ROUTE 68), POST MILE 72.0 TO 75.1, MONTEREY COUNTY, CALIFORNIA. AN - 36385937; 1037 AB - PURPOSE: Alternatives to improve Highway 1 from the Carmel River Bridge to the existing Route 68 (west)/Highway 1 interchange near Carmel in Monterey County, California are evaluated. Alternative 1 would place Highway 1 on a new alignment through Hatton Canyon, east of the existing Highway 1 alignment. New roadway features would include construction of approximately 2.2 miles of four-lane controlled access scenic roadway and 0.9 mile of two-lane conventional highway. Alternative 3 would widen the existing Highway 1 to three lanes from Carmel Valley Road to Morse Drive and would improve the existing three-lane section from Morse Drive to Ocean Avenue. New roadway features would include an additional northbound lane from Carmel Valley Road to Morse Drive. Alternative 4 would widen the existing Highway 1 to four 12-foot lanes with 8-foot paved shoulders from Rio Road to Ocean Avenue. Left-turn channelization would be provided for all public road connections between Carmel Valley Road and Ocean Avenue. Alternative 6 would widen the existing Highway 1 to four lanes from Rio Road to Carmel Valley Road. From Carmel Valley Road to Carpenter Street, Highway 1 would be widened to six lanes, with a two-way left-turn lane. The existing 32-foot Carmel River Bridge would be widened to a 44-foot, two-lane section. South of the bridge, the 44-foot section would conform to the existing section. Alternative 7 would place Highway 1 on a new alignment through Hatton Canyon and would widen the existing Highway 1 northbound roadway to three lanes from Carmel Valley Road to Ocean Avenue. The Carmel River Bridge would be replaced and the Hatton Canyon Sewer Line would be relocated. There were no proposals for Alternatives 2 and 5. Project costs would vary from $25.6 million to $2.7 million depending on the alternative selected. POSITIVE IMPACTS: The improvements would provide additional capacity on Highway 1 and would reduce crossing and turning conflicts associated with the existing highway and several local streets and private driveways. NEGATIVE IMPACTS: Negative impacts include the loss of 26 acres of pine forest, 160 acres of wildlife habitat, and 5 acres of riparian woodland (Alternative 1); significant noise impacts and adverse aesthetic impacts (Alternative 3); loss of riparian vegetation (Alternative 4); impacts to Hickman's Onion, a candidate endangered species, and traffic delays (Alternative 6); and loss of 5.7 acres of prime agricultural land (Alternative 7).

Preparation date: October 29, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FEDERAL AID PRIMARY ROUTE 412, U.S. ROUTE 51, FROM NORMAL TO OGLESBY, ILLINOIS. AN - 36404192; 1085 AB - PURPOSE: Construction of a four-lane, divided highway, designated as Federal Aid Primary Route 412 (F.A.P. 412) from Interstate Route 55 (I-55) at Bloomington-Normal to north of Illinois Route 71 near Oglesby is proposed. The highway would be located in McLean, Woodford, Marshall, and LaSalle counties along or near existing U.S. 51. The length of the project, which extends in a north-south direction, would be approximately 51 miles. The preferred alternative, a fully access-controlled freeway, is a combination of the F-85 freeway alternative that makes optional use of U.S. Route 51 rights-of-way, as well as using portions of the F-76 freeway alternative where possible. Traffic would be separated by a 54-foot wide median. The integrity of the local road system would be preserved by carrying important local roads over or under the new highway by means of grade separations and by retaining portions of the existing U.S. 51 pavement as a frontage road for the new four-lane facility. Existing access to single-family residences and farms would be provided directly to the highway or by frontage roads and service drives. Median crossings would be spaced approximately one-half mile apart. POSITIVE IMPACTS: The proposed highway would provide a safer and more efficient transportation system by relieving the problems of traffic congestion and conflicts between farm equipment and high-speed traffic, and by reducing accident rates along existing U.S. 51. NEGATIVE IMPACTS: As a result of the proposed plan, 10 residences would be displaced. Seven businesses would also be displaced. Approximately 1,876 acres of farmland would be converted to highway rights-of-way. For all construction alternatives, the noise abatement criteria are exceeded at the trailer court situated in the southwest quadrant of the F.A.P. 412/I-55 interchange. Other sites, primarily farm residences along the route, would also be affected. The plan would create 12 landlocked parcels and would cause adverse travel for farmers along the route. The recommended plan would remove approximately 10 acres of wetlands. LEGAL MANDATES: Executive Orders 11988 and 11990, and Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

AN - 36400736; 1016 AB - PURPOSE: The Bonneville Power Administration (BPA) proposes to increase the capacity of the Pacific Northwest-Pacific Southwest Intertie and to develop a Long Term Intertie Access Policy (Intertie Access Policy or IAP) for the BPA-owned parts of the Intertie. These proposals would enable short- and long-term contractual sales and transfers of surplus federal power and management of other interregional transfers of power over the Pacific Northwest-Pacific Southwest Intertie. Intertie capacity, presently 5,200 megawatts (MW), is being increased to 6,300 MW and may be increased further to approximately 7,900 MW. Access for regional and extraregional entities to BPA's portions of the Intertie is now governed by the Near Term IAP. Intertie access could be regulated by returning to a first-come, first-served approach or by a combination of options. These options include different ways to allocate capacity for transfers of nonfirm power; ways to provide assured access to the Intertie for long-term firm power sales; ways to consider appropriate access for power from new resources; ways to permit or restrict access for hydroelectric resources that may adversely affect BPA's efforts to protect fish and wildlife; and ways to consider allocation of Intertie access for entities outside the Pacific Northwest (PNW) region. POSITIVE IMPACTS: Capacity increases would create decreases in air pollution from reduced gas and oil generation in California and the Inland Southwest. Forced spills at dams would be reduced with mixed effects on fish survival. The option granting BPA first access would slightly decrease PNW air pollution. NEGATIVE IMPACTS: Capacity increases would create small increases in air pollution from coal generation in the PNW. The option granting BPA first access would slightly increase air pollution in California compared to other nonfirm allocation options. It would also reduce some fish stock survival rates. Long-term firm contracts would allow some new resource construction to be deferred in both the PNW and California.

AN - 36404895; 1040 AB - PURPOSE: Implementation of a plan for improvements to Iowa Highway 415 at Saylorville Lake in Polk County, Iowa is proposed. The project would modify Iowa Highway 415 and connecting roads in the vicinity of Ankeny, Crocker Township, Polk County, Iowa. The preferred alternative would extend for approximately 5.4 miles from the junction of existing Highway 415 and Northwest 78th Street, westerly, generally parallel with Northwest 78th Street for one mile, then would turn northward and extend north along the east side of Saylorville Lake until it intersects the Barrier Dam roadway just east of the Big Creek Barrier Dam. The estimated cost of the project is $11.4 million, which includes all rights-of-way acquisition, engineering design, supervision and administration, and construction costs. POSITIVE IMPACTS: The major impact of this highway project would be improved capacity, safety, and convenience for road users. The selected plan would coincide with land-use plans of Ankeny and Polk counties. The plan would provide highway access to areas of planned subdivisions. The improved highway would promote a slight increase in population. Property values, particularly those in the Rock Creek area, could be expected to increase. Tax revenues may also be expected to increase slightly. Accessibility to recreational facilities would improve, as would police, ambulance, firefighter, and other emergency services. The proposed plan would promote regional growth, and employment should increase during construction and perhaps permanently. Fourteen residences should have lower levels of highway traffic noise. Mitigation plans include creating 24 acres of wetland habitat, planting 153 acres of hardwood, and planting 114 acres of native grasses. NEGATIVE IMPACTS: One building may have to be relocated. There would be a noticeable loss of scenery and other aesthetic values in the Rock Creek area. Approximately 86 acres of farmland would be required for rights-of-way. A temporary elevation of emissions would occur from construction machinery; approximately eight residences would suffer from increased highway traffic noise. The plan would cause significant impacts to wildlife habitat from destruction of upland forest.

AN - 36393866; 1039 AB - PURPOSE: Construction of a new location four-lane divided roadway from Abercorn Street/S.R. 204 northeast to S.R. 21/I-516/Lynes Parkway in Savannah, Chatham County, Georgia is proposed. The partially controlled access primary facility would be approximately 5.7 miles in length and consist of four lanes, two in each direction, separated by a 20-foot wide raised median. Rights-of-way requirements would be 200 feet. The project would begin with an at-grade intersection at Abercorn Street/S.R. 204 at a point approximately one mile west of the Abercorn Street/S.R. 204 crossing of Little Ogeechee River. The alignment would follow a north direction to the approach to the Seaboard Coast Line Railroad. The alignment would then shift to the northeast, bridging the railroad and the Little Ogeechee River, and continue in a northeast direction generally paralleling the railroad and crossing local streets at-grade. The project would terminate with a full-service interchange with S.R. 21/I-516/Lynes Parkway at a point where S.R. 21 extends from a north/south direction to an east /west direction. POSITIVE IMPACTS: The project would reduce traffic and improve safety on Abercorn Street /S.R. 204. NEGATIVE IMPACTS: All phases of construction would temporarily contribute to air pollution, and construction equipment would produce slight amounts of exhaust emissions. The project would result in substantial noise increases of 19 to 20 decibels over existing levels. A total of five residential sites would be above noise abatement criteria. The project would permanently displace approximately seven residences and two businesses and approximately 24.2 acres of wetlands.

AN - 36393915; 1041 AB - PURPOSE: Implementation of a plan to relocate U.S. Route 44 from State Route 58 in Carver to State Route 3 in Plymouth, through the towns of Carver, Kingston, Plympton, and Plymouth, all in Plymouth County, Massachusetts, a distance of 7.48 miles, is proposed. Two lanes would be constructed in each direction, with four interchanges. The project also includes improvement of Route 3 between the existing Cherry and Samoset street interchanges, as well as improvement of the Samoset Street interchange. The entire length of the new highway would have a closed drainage system to avoid adverse effects on the underlying Plymouth Aquifer and on the wetlands through which it must pass. The acres of wetlands to be removed, other than cranberry bogs, will be replaced by 29.6 acres of created wetlands. The 1984 estimated cost is $48.5 million. POSITIVE IMPACTS: The proposed project would divert traffic now using local neighborhood streets to reach a plant with large employment. East-west movement of traffic would be facilitated for the considerable tourist attractions in the area, thereby alleviating conditions on local roads and improving the economic development of the region. Through and local traffic would be separated, thereby lowering the accident rate and relieving congestion. A closed drainage system would be provided throughout the length of the route, thereby shielding the Plymouth Aquifer. NEGATIVE IMPACTS: The preferred alternative would require the relocation of 28 properties, of which 22 are residential, 5 are commercial and 1 is residential/commercial. Approximately 28.7 acres of wetlands would be removed, of which 5.16 acres are cranberry bogs. Approximately 26 acres of the Kingston State Forest and 9.4 acres of Camp Nekon, which is owned by the town of Kingston, would be acquired. The rights-of-way would cross the Annasnappet Archaeological District. Relocation of Route 44 would result in a major new source of noise in what is now a very quiet environment.

Preparation date: October 17, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED LAKE ALMA PROJECT, ALMA, BACON COUNTY, GEORGIA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1986). AN - 36399504; 1049 AB - PURPOSE: The city of Alma and Bacon County, Georgia have applied for a Department of the Army permit pursuant to Section 404 of the Federal Water Pollution Control Act of 1972 to discharge fill material into U.S. waters during construction of 14 impoundments and an emergency access road around the northern portion of the land acquired on Hurricane Creek upstream of the proposed Lake Alma project in Alma, Georgia. This draft supplement to the final environmental impact statement would enable the regulatory authority to evaluate what impacts the Mitigation Plan would have on the environment of the Alma/Bacon County area. The dams, roads, and other measures constitute the Mitigation Plan for the Lake Alma project, which has already received a Department of the Army permit. The current application would require the discharge of approximately 101,030 cubic yards of fill material that would be obtained from on-site high-ground borrow areas. The dams would create 14 greentree reservoirs and lakes containing a total of approximately 194 acres. The greentree reservoirs would be allowed to fill beginning November 1 and should attract migratory waterfowl. Several other measures were included in the Mitigation Plan, including the construction of a 30-foot-wide emergency vehicle access road and rights-of-way; placement of wood duck boxes every 100 feet along the stream bank and rights-of-way; and annual planting of roadbed and rights-of-way with a mixture of grain crops for wildlife food. The greentree reservoirs would be drawn down by February 15th when the vernal greening begins. While drained, certain areas would be planted with millet or corn, and additional planting of oak trees for mast production would occur. Appropriate erosion control measures would be used to minimize erosion and sloughing of slopes. Approximately 17 culverts, adequate to maintain expected flows, would be used in the road, and four bridges would be constructed. POSITIVE IMPACTS: During the periods of the year when much of the vegetation is dormant, most of the impoundments would act as greentree reservoirs to provide habitat for waterfowl. The greentree management would result in the enhancement of approximately 137 acres of existing wetlands for waterfowl and the construction of approximately 23 acres of new wetlands. Construction of the Mitigation Plan is expected to increase the recreation potential of the region by allowing construction of Lake Alma and by increasing waterfowl hunting at specific times during the year. NEGATIVE IMPACTS: The construction of permanent pools for production would result in filling or flooding of approximately 35 acres of existing wetlands. The emergency access road would require approximately 13,000 cubic yards of fill material, of which approximately 2,000 cubic yards would be discharged in wetlands, filling approximately 0.5 acre.

AN - 36380690; 1048 AB - PURPOSE: Construction of Lake Alma on Hurricane Creek to provide water-oriented recreation opportunities in Alma, Bacon County, Georgia, is proposed. Alma is located in southeastern Georgia within the Lower Atlantic Coastal Plain, 75 miles west of the Atlantic coastline. The project would provide a reservoir 37,000 feet in length with an average width of 1,900 feet, encompassing 1,300 to 1,500 surface acres. An earthen dam with a concrete spillway would be constructed 4,000 feet downstream from the bridge on State Highway 32. The spillway would accommodate a 3-foot rise in the water level to contain a flood reaching the 100-year maximum level. The reservoir would have an 800-acre area for water-oriented uses, a 400-acre area for less active water-oriented uses, and 200 acres would be maintained in a natural condition. This final environmental impact statement (FEIS) adopts the FEIS filed by the Department of Housing and Urban Development in December 1976 for the purpose of filing a permit application under Section 404 of the Clean Water Act. POSITIVE IMPACTS: Initially, Lake Alma would attract 78,000 persons annually and 164,000 annual visitors by the year 2000. The project would increase employment and income in the county. Water quality in ecosystems downstream from the damsite would improve due to the entrapment of pollutants in the lake. The reservoir would stimulate residential and commercial development, increase economic and social development, and provide additional water-oriented recreation opportunities. Creation of the lake would increase the diversity of habitats in the area. NEGATIVE IMPACTS: The project would destroy terrestrial fauna through the inundation of 1,400 acres of land. Construction of the reservoir and related facilities would generate siltation and turbidity downstream from the project.

AN - 36397268; 1038 AB - PURPOSE: Construction of a new multilane roadway with a transit element in the median between I-85 and I-285 in Fulton County, Georgia is proposed. The project includes new connector routes in Buckhead and near I-285 to provide interchanges with the mainline and is approximately six miles in length. The preferred alternative entails six 12-foot lanes from I-85 on the south, approximately 2,000 feet southwest of Lenox Road, to I-285 on the north at the present terminus of GA 400. Six 12-foot lanes, with a minimum 35-foot wide mass transit median separated by barriers, are proposed. The estimated cost of rights-of-way acquisition and construction is $268 million, exclusive of any work within the transit median other than grading and drainage. POSITIVE IMPACTS: Air quality in the region would improve and would be in compliance with state and federal Ambient Air Quality Standards. Noise levels would decrease in streets with reduced traffic. Traffic would be reduced on many neighborhood collector and arterial streets. The extension would be a safer facility than surface streets in the area, and the total number of accidents in the study area would be reduced. North/south travel times through the corridor would generally decrease. The closure of certain roads could tend to strengthen community cohesion. Access for emergency vehicles would generally improve. The project would increase commercial property values in areas near interchanges. The project offers significant opportunities for increased economic activity. NEGATIVE IMPACTS: Where neighborhoods would be divided by the GA 400 extension and associated connector roads, cohesion between the separated units would be reduced. The project would increase traffic on I-85 south of GA 400 and on some streets north of I-285. Where traffic volumes on surface streets would increase, there could be a corresponding increase in accidents. In some cases, where roads would be closed, east/west travel times may be slightly longer. Noise levels would increase for some locations close to the new facility. The project would displace approximately 116 residences and businesses on private property and an additional 31 residences located on land owned publicly, many of which are tenant occupied, for future rights-of-way. Two areas of wetlands would be impacted, with a total displacement of 6.6 acres. Approximately 200 acres of natural area remnants would be cleared, with a resulting loss in wildlife habitat.

AN - 36395111; 1045 AB - PURPOSE: Implementation of a flood control project on the Guadalupe River between Highway 17 and Highway 280 in downtown San Jose, California is proposed. The recommended plan consists of approximately two miles of channel improvements between highways S-17 and I-280, including covered channels necessary to incorporate the locally constructed underground concrete conduit bypass. The project is designed to convey the estimated 100-year-frequency flood event without damage. Downstream of the locally constructed conduit section, approximately 130 linear feet of similar conduit construction would tie the bypass into the existing Guadalupe Channel. The covered conduit section was found to be more costly than a fenced, open, rectangular concrete channel of similar length. Since no extraordinary safety concerns could be identified in this reach, the cover has been included as a local betterment. The first cost of this betterment is estimated at $207,000. Upstream of the locally constructed conduit section, approximately 600 linear feet of similar covered conduit construction would tie the bypass into the existing Guadalupe Channel immediately downstream of the project entrance structure in the vicinity of I-280. The use of a covered concrete section in this location is required for public safety. Fish and wildlife mitigation measures would include the planting of native riparian vegetation on 5.3 acres of project lands. Improvement of nine acres of existing wildlife habitat on both sides of the previously improved channel downstream of S-17 to Brokaw Road would also be included in the mitigation plan. The first cost of the proposed plan is $32.6 million, including $17.7 million to the U.S. government and $14.9 million to nonfederal interests. Average annual benefits would be $4.5 million, with a benefit to cost ratio of 1.4. POSITIVE IMPACTS: Flood control measures would reduce future flood damages to public and private property and to business activities in the 100-year floodplain, with the associated cost savings related to reconstruction costs, emergency aid, and flood insurance costs. The local urban redevelopment potential would be enhanced, and the commercial development of a small parcel of land within the floodplain would occur more rapidly. NEGATIVE IMPACTS: The project would involve the loss of riparian, fish, and wildlife habitat, and would reduce the aesthetic quality of the river. Homes and businesses would be displaced, disrupting the existing community cohesion. Some utilities and public services would be disrupted temporarily, and some access routes would require relocation. Archaeological resources and some historic residences and bridges would be damaged.

AN - 36405804; 1042 AB - PURPOSE: Implementation of a plan to upgrade 10 miles of the Hayesville Interchange to the Battle Creek Interchange section of Interstate 5 through Salem, Oregon is proposed. The preferred alternative proposes to widen 10 miles of the existing freeway from four lanes to six lanes and to modify three interchanges. The interchanges are the Hayesville Interchange at I-5 and Portland Road, the Market Street Interchange at I-5 and Market Street, and the Santiam Interchange at I-5 and Santiam Highway. Three options (modified diamond, split diamond, and partial cloverleaf) are considered for the Hayesville Interchange, three options (modified diamond, simple diamond, and urban diamond) are considered for the Market Street Interchange, and two options (partial cloverleaf with directional ramps and partial cloverleaf with diamond ramps) are considered for the Santiam Interchange. The mainline cross section would consist of six lanes with a 50-foot-wide divided median to provide for a future fourth lane of travel in each direction. The vertical alignment of the alternative would be the existing profile, with the exception of a portion near Mill Creek where the grade would be raised to keep the pavement base above the 100-year flood elevation. Existing freeway overpasses and underpasses would be replaced with structures that allow for the planned street improvements. Two railroad overpasses would be raised. POSITIVE IMPACTS: The preferred alternative would result in a stable traffic flow with improved safety and the capability to accommodate projected I-5 traffic growth beyond the year 2012. Air quality would be improved due to the reduction in traffic congestion. The acoustical environment would also be improved as a result of the construction of acoustical barriers. NEGATIVE IMPACTS: Depending on the build alternative interchange options selected, from 67 to 81 acres of rights-of-way would be required. Associated with this acquisition would be the displacement of 12 to 35 housing units and from 17 to 34 businesses. From 221 to 380 jobs would be displaced. Upland habitat within the rights-of-way totaling 177 acres would be lost, together with 4 acres of wetland habitat. The wetland habitat would be replaced with construction of roadside and interchange stormwater detention basins. The build alternative would impact several archaeological sites in the Santiam Interchange area.

AN - 36387671; 1047 AB - PURPOSE: Implementation of a plan for supplementing the existing dry-year and emergency water supply capacity to the San Diego Aqueduct System is proposed. The preferred alternative would involve construction of a dam along the Santa Ysabel Creek and inundation of Pamo Valley for emergency and dry-year water storage. The reservoir would have a capacity of 130,000 acre feet of water. Major components of this plan include construction of a 264-foot high roller-compacted concrete dam with a built-in spillway; installation of a 54-inch, 19-mile pipeline from the reservoir west to the Second Aqueduct; installation of a 36-inch pipeline intertie to Lake Sutherland with a hydroelectric facility; establishment of a fishing concession and limited day-use picnic area by the city of San Diego; mitigation for project-associated impacts to environmental resources, including compensation for impacts to biological resources; minimization of water and air quality effects during construction; water releases and water reclamation to improve water quality and to maintain water supplies; and reduction of impacts to cultural resources through a multiphased mitigation program. The estimated costs would be $84.7 million, plus $20,000 for a water reclamation project. POSITIVE IMPACTS: The project would guarantee the reliability of San Diego's regional water supply during emergencies and drought situations. Hydroelectric energy would be developed to reduce the demand for other energy resources. The project would create new recreational opportunities. NEGATIVE IMPACTS: Construction of pipelines would involve trenching that would temporarily alter the physiography and potentially increase sedimentation of downstream areas. There would be a short-term decline in water quality during construction. A direct and permanent loss of all vegetation would result within the inundation area, with significant adverse impacts on wildlife and wildlife habitat. The project would displace 30 residents.

AN - 36400114; 1053 AB - PURPOSE: Construction of a navigation channel and associated port facilities on the Mississippi River in the Cape Girardeau/Scott City area, Cape Girardeau and Scott counties, Missouri is proposed. The project would involve construction of a slackwater channel, 1,800 feet long, 230 feet wide, and 9 feet deep, along the west bank of the river at approximately river mile 48.0 near Grays' Point. Excavated material would be used to create an 8-acre landfill riverside of the harbor channel and a 27-acre landfill on the landward side. This land and adjacent upland areas would be used by local interests for industrial development. Estimated total first cost of the project is $4.1 million, and the benefit-cost ratio is 1.18. POSITIVE IMPACTS: The availability of waterway transportation on a public use basis could stimulate desirable commercial and industrial growth, with associated increases in employment, tax revenues, and property values. NEGATIVE IMPACTS: The project would involve the loss of 21 acres of upland forest, 19.8 acres of bottomland forest, 4.9 acres of wooded swamp (20.7 acres of wetlands), 50.3 acres of agricultural land, 6.0 acres of quarry disposal land, and 84.0 acres of floodplain.

Preparation date: October 8, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SECOND LOCK AT LOCKS AND DAM NUMBER 26 (REPLACEMENT), MISSISSIPPI RIVER, ALTON, ILLINOIS AND MISSOURI. AN - 36398337; 1050 AB - PURPOSE: Construction of a 600-foot second lock at Locks and Dam No. 26 (Replacement), located on the Mississippi River near Alton, Illinois, is proposed. Under the preferred alternative, the second lock, 600 by 110 feet, would be built between the authorized lock and the Illinois bank and would be constructed of concrete and steel on foundation piling. The most probable staging area for this lock would be on the Illinois bank adjacent to the construction site, riverside of the levee. A portion of this area was built up during the construction of the single lock and is approximately 18 acres in size. If additional area is needed, the contractor could either use areas in Missouri left from the single-lock construction that would not be inundated by the new pool or work from barges in the river. A cofferdam would be constructed to build the second lock. The downstream cofferdam arm would be constructed approximately 500 feet downstream of the one required for construction of the closure structure with no second lock and would use cells from the second-stage cofferdam. Since the same number of cells would be constructed in the third stage for either the single replacement lock or the second lock plan, the same amount of sand would be required to fill the new cells. More stability berm would be required inside the cofferdam for the second lock plan. Following completion of the second lock, the cofferdam would be removed. In addition to the second lock, the third stage would consist of construction of 1-1/2 gatebays of the dam. The duration of third-stage construction would be approximately three years. POSITIVE IMPACTS: The major positive impact would be on commercial transportation, with a 27 percent increase in the traffic level over that attained without construction. Traffic levels project that annual navigational tonnage would reach 174.4 million tons by the year 2040. A slight increase in bottomland forest would occur, with a positive impact on big and small game hunting. NEGATIVE IMPACTS: Increased traffic would result in erosion, suspended sediment and turbidity, and backwater sediment. Backwater recreational opportunities would decrease due to sedimentation effects. Increased impacts would be expected on cultural resources due to induced bank erosion and drawdowns. Site burial would occur in certain areas due to sedimentation.

AN - 36386901; 1036 AB - PURPOSE: Construction of a modern multilane highway, to be located in Jefferson County, Alabama, is proposed. The project would begin near the Walker/Jefferson County Line and extend eastward until it intersects U.S. Highway 31 in the Birmingham metropolitan area, a distance of approximately 16 miles. This would be a freeway type facility with access limited to grade separation interchanges. Projected 20-year traffic volumes range from 24,150 vehicles per day to 60,794 vehicles per day. The minimum rights-of-way width would be 300 feet. Three alternative locations are under consideration: (1) Alternate 1 would begin near the Walker /Jefferson County Line north of the community of West Jefferson and would end at its intersection with U.S. Highway 31 near the communities of Greenlea Heights and North Birmingham. The approximate length of the alternate would be 16.11 miles, with an estimated cost of $80.4 million. (2) Alternate 2 also would begin near the county line and would terminate at the intersection of U.S. Highway 31 in the Fultondale area, involving the cities /communities of Snowtown, Alden, Blossburg, Republic, Upper Coalburg, Birmingham, and Fultondale for approximately 16.87 miles. The estimated cost would be $76.8 million. (3) The length of Alternate 2-1 Revised would be approximately 16.53 miles, the first 11 miles of which would be the same as Alternate 2, at an estimated cost of $94.3 million. POSITIVE IMPACTS: The primary positive effect would be improved transportation and economic growth. The project would enhance safety. Time and energy would be saved as a result of the free-flowing traffic facility. The local economy would be stimulated by the proposed project, and the economy of this Appalachian region should improve with the completion of Corridor "X." NEGATIVE IMPACTS: Alternate 1 would require the relocation of 130 residences, 7 businesses, and 4 nonprofit organizations. Alternate 2 would require the relocation of 51 residences and 7 businesses. Alternate 2-1 would require the relocation of 100 residences, 7 businesses, and 4 nonprofit organizations. Other negative effects would include the conversion of land to highway and rights-of-way and the loss of wildlife habitat. Some businesses in the cities and towns along the project corridor may experience a small decrease in business from any through traffic that may have stopped in the downtown area. There would be some erosion and water pollution during construction, plus some air and noise pollution.

Preparation date: October 2, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TUG FORK VALLEY FLOOD DAMAGE REDUCTION PLAN, BIG SANDY RIVER BASIN, WEST VIRGINIA, KENTUCKY, VIRGINIA: WEST WILLIAMSON, WEST VIRGINIA STRUCTURAL PROJECT (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF DECEMBER 1982). AN - 36394019; 1058 AB - PURPOSE: Implementation of a flood control and management plan for communities within the 1,555-square-mile valley of the Tug Fork of the Big Sandy River in West Virginia, Kentucky, and Virginia is proposed. The tentatively selected plan would include floodwall/levee projects for nine of the valley's major community centers; voluntary relocation of existing structures below the 100-year flood level or the April 1977 flood level, whichever is greater; creation of flood-safe developable land to accommodate anticipated future residential growth; and provisions for physically relocating or floodproofing structures located below the 100-year flood level or the April 1977 flood level, whichever is greater. New housing for displaced residents would be located at the Matewan Big Bend Cutoff fill project as well as at other new housing and community development sites throughout the valley. The plan would include measures for floodplain zoning, flood insurance, and emergency flood warning and evacuation. The nine communities for which structural protection would be implemented would be the Williamson Central Business District, Matewan, Stepptown, West Williamson, Kermit, and Crum in West Virginia and South Williamson, Warfield, and Lovely in Kentucky. Pedestrian facilities, such as trails, overlooks, and facilities to ease access to the river for recreational purposes, would be provided. The Matewan Big Bend Cutoff fill project, which would constitute a component of the tentatively selected plan, would consist of excavation of 7.0 million cubic yards of material to create an open cut, with a length of 1,300 feet and a depth of 300 feet, through the neck of the 4.5-mile loop of Tug Fork just downstream of Matewan, West Virginia and Buskirk, Kentucky. Tug Fork would be relocated through the cut, excavated material would be placed in the existing channel to create developable land, and West Virginia State Route 49 (S.R. 49) would be relocated through the cut. Estimated cost of the project is $289.4 million. This Supplemental Information Report addresses modifications and refinements to the West Williamson Structural Project. The modifications and refinements include (1) selection and development of a borrow and spoil site (Oil Well Hollow); (2) construction of a haul road from the project site to the borrow/spoil site; (3) a temporary construction bridge across the Tug Fork River; (4) additional floodwall foundation excavation; (5) channel modifications; (6) an increase in floodwall height; (7) a wall alignment change at railroad tunnels; and (8) modifications and changes to closure gates. In addition, the landscaping /mitigation plan presented for proposed floodwalls has been refined. POSITIVE IMPACTS: The project would provide flood protection for the nine communities, create a large amount of developable land in the cutoff area, and shorten travel time on West Virginia S.R. 49 within the project area. An estimated 4,545 residential units located on 553.8 acres of land and 2,539 nonresidential structures on 4,798 acres of land would be protected from flooding. Flood flows along a 10-mile reach of the waterway would be reduced, and a major housing and community development site would be created within the area bypassed by the cutoff. NEGATIVE IMPACTS: Excavation for the cutoff would result in pronounced short-term increases in turbidity downstream of the excavation site and destruction of 125 acres of riparian bottomland and upland hardwoods. Disposal of material from the cutoff would result in the loss of some vegetative communities. Other land development under the plan would require clearance of 444 acres of vegetation. Approximately 4.5 miles of riparian habitat and 209 acres of associated terrestrial habitat and recreational land would be lost when the river is rechanneled. The cutoff would increase stream velocity, increasing levels of suspended solids and scouring tendencies downstream. A total of 936 acres of land within Tug Fork Basin, including agricultural, commercial, residential, riparian, and upland areas, would be disturbed by the project. Numerous residential and business structures would be displaced.

AN - 36398535; 1012 AB - PURPOSE: The expansion of Stapleton International Airport (SIA) in the city and county of Denver, Colorado is proposed. The preferred expansion alternatives involve an east-west runway located on Sections 11 and 12, T3S, R67W, and affecting Section 7, T3S, R66W, and a short north-south runway located partially on Section 9 in Adams County on the Rocky Mountain Arsenal, a Department of Defense installation. The short north-south runway is also located partially on Section 16 of the SIA. The direct costs for the East-West Alternative and the short North-South Runway Alternative are estimated to be $78 million. POSITIVE IMPACTS: While neither runway is dependent on the other, in combination they would minimize delay to the extent practicable at the SIA. Airline operating costs would decrease. The shorter delays of aircraft on the ground would provide less surface water runoff pollution and improve water quality in the drainage basins. Shortening delays will reduce fuel usage. NEGATIVE IMPACTS: The proposed plan would result in an increase in the amount of land area affected by airport-related noise. Increased aircraft traffic in the future will cause greater pollutant emissions. The pollutant loading to the runway during dry weather will be rinsed off during rain events and will result in increased contaminant levels in surface water and groundwater. The preferred alternative would remove approximately 590 of the 2,560 acres on the southern tier from public use. The short north-south runway would eliminate approximately 210 of the 640 acres on Section 9 currently used for dog trials. Construction of the runway would affect the biotic communities. The preferred alternative would result in the loss of 25 acres of wetlands. Since the runways, taxiways, and surrounding surface would decrease surface permeability, they would add to flooding problems.

Preparation date: September 30, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DEER CREEK DAM AND RESERVOIR MUNICIPAL WATER SUPPLY PROJECT, CONVERSE AND NATRONA COUNTIES, WYOMING. AN - 36386106; 1059 AB - PURPOSE: Implementation of a plan for the construction of a dam and reservoir on Deer Creek, a tributary of the North Platte River in southeastern Wyoming, to provide a reliable municipal water supply for the city of Casper, Converse County, Wyoming is proposed. The dam would impound a reservoir of approximately 66,000 acre-feet over 1,050 acres of land. Two alternative scenarios are proposed: Scenario 1 assumes that the U.S. Bureau of Reclamation's (USBR) North Platte Project would operate as it has historically, with no changes, including deliveries to the Inland Lakes. The Deer Creek project would be allowed to store water only after all senior water rights have been satisfied and after the Inland Lakes have been filled. The Deer Creek project would realize a firm annual yield of 64,000 acre-feet under this scenario. Scenario 2 assumes that the Inland Lakes would have a current-day Wyoming water right and would be allowed to fill from surplus natural flow after all senior water rights, including the Deer Creek project, have been satisfied. Under this scenario, it is assumed that the Inland Lakes would accrue the natural flow of the North Platte River in Wyoming when surplus was available, then from North Platte Project storage, if needed. The Inland Lakes would receive the same amount of water at the same times as they have in the past under this assumption. A firm annual yield of 9,600 acre-feet would be provided by the Deer Creek project under this scenario. The Deer Creek project would involve 1,850 acres of land. Rangelands and free-flowing streams would be converted to a reservoir with adjacent recreation and wildlife management lands. Seven miles of stream fishery would be replaced by a reservoir fishery. A public fishing easement would be provided throughout the six-mile Deer Creek Canyon below the dam. A boat ramp, parking lot, and access roads would be constructed. POSITIVE IMPACTS: An estimated 4,100 visitors and $66,000 in benefits would be drawn from other reservoirs. The project would provide year-round minimum release flows. This would improve the stream habitat downstream from the dam. An estimated 40 acres of wetlands would be created by the presence of the reservoir. A 490-acre tract of land adjacent to the reservoir would be managed for recreation and wildlife. Recreation benefits of $359,000 per year would be realized by the Deer Creek project in the year 2000. NEGATIVE IMPACTS: Projected releases and release temperatures may adversely affect trout spawning and survival. More than 1,000 acres of various habitat types would be inundated by the Deer Creek Reservoir. Approximately 120 acres of willow-wet meadow habitats would be flooded. Under Scenario 2, critical habitat of the federally endangered whooping crane, the interior least tern, and threatened piping plover may be affected. Eleven recently discovered cultural resource properties that are potentially eligible for the National Register of Historic Places would be impacted. There would be an average annual depletion to the North Platte River of 8,760 acre-feet under Scenario 1 and 11,940 acre-feet under Scenario 2.

AN - 36400176; 1055 AB - PURPOSE: Implementation of a flood damage reduction plan for Malheur Lake in Harney County, Oregon is proposed. Malheur Lake, a terminal lake in a closed drainage basin in southeastern Oregon, has experienced extensive surface elevation increases due to high inflows in recent years. Approximately 100,000 acres have been flooded above the typical historic lake surface area of 40,000 to 60,000 acres. The continued high lake elevation has caused severe economic damage in the region. One structural and two nonstructural alternatives to reduce damages in the current and future flooding cycles have been examined. These alternatives are diversion of water from the lake to the Malheur River, purchase of flooded lands, and relocation of a flooded railroad line. A single preferred plan or course of action is not identified. Rather, the best structural and the best nonstructural plans are identified. The structural plan consists of diversion of water from Malheur Lake to the Malheur River via a 500 cubic feet per second (cfs) canal operated from October through April, with lake target elevation of 4,095 mean sea level (msl), and the purchase of flooded private land below elevation 4,095 msl. The plan incorporates measures to mitigate adverse environmental effects. The nonstructural plan consists of relocation of the flooded portion of the Eastern Oregon Branch of the Union Pacific Railroad and purchase of flooded private land below elevation 4,095 msl. Estimated first costs for the structural and nonstructural plans are $20.9 and $4.6 million, respectively. POSITIVE IMPACTS: Implementation of the structural plan would prevent approximately 58 percent of flood damages expected in the future without project activity and would provide power benefits from energy generated at existing hydropower facilities at dams on the Snake and Columbia rivers. A key positive aspect is that some benefit would be provided to all damage categories. Because the railroad represents a significant damage category, the nonstructural alternative would prevent approximately 52 percent of future damages expected in the without project condition. NEGATIVE IMPACTS: The major disadvantages of the structural plan are related to adverse environmental effects such as erosion of archaeological sites and expected losses to the Malheur River trout fishery. A significant disadvantage is that other damage categories such as roads and highways, utilities, and agricultural lands above 4,095 msl would not be provided protection from current or future flooding.

Preparation date: September 26, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ZIMMER CONVERSION PROJECT, OHIO RIVER BASIN, CLERMONT COUNTY, OHIO. AN - 36379916; 970 AB - PURPOSE: Conversion of the uncompleted Wm. H. Zimmer Nuclear Power Plant into a 1,300 megawatt (MW) coal-fired electrical generation plant is proposed. The site is located near Moscow in Clermont County, Ohio and consists of approximately 269 acres along the floodplain of the Ohio River west of U.S. Highway 52. The proposed new structures and facilities would include a turbine room; a boiler room; a bottom ash and pyrites handling system; a precipitator; a fly ash removal system; a flue gas desulfurization system; a stack; barge unloading, material handling, and storage facilities; wastewater and clear water ponds; and a metal-cleaning waste collection and treatment facility. The proposed solid waste disposal area, located approximately three miles east of the plant, would be designed to contain bottom ash, pyrites, and fly ash-fixated waste products for the life of the plant. Barge unloading facilities would be located on the river front to unload coal, fuel oil, and lime. On completion of construction activities, final landscaping would consist of plantings along the entrance road, guard house, and service building. It is estimated that conversion of the Zimmer plant to coal would require an additional project cost of $1.8 billion by 1991, bringing the total Zimmer project cost to $3.6 billion. POSITIVE IMPACTS: Construction and operation of the conversion project would have a positive effect on employment and income. It is estimated that it could result in an addition of 165 workers and dependents to the local area. Taxes payable to various governmental authorities would increase, especially on the local level. NEGATIVE IMPACTS: Construction would affect air quality in the immediate vicinity of the site. The plant would withdraw 3.1 million gallons per day of groundwater for several uses. Water quality would be affected by an increase in turbidity at the plant site during construction and afterwards. Aquatic habitat modifications would occur in the lower reach of Little Indian Creek and along the banks of the Ohio River. The conversion project would involve the consumption of 3.5 million tons of Ohio coal annually.

AN - 36404776; 966 AB - PURPOSE: A program is proposed for testing and evaluating the potential propagation of a ground-based free electron laser beam through the atmosphere to desired diagnostic targets without significant reductions in the beam's quality and energy levels. The project would be located at one of three potential sites at the White Sands Missile Range, New Mexico. It would be conducted in two phases, a low-power phase and a high-power phase. Construction of the low-power laser facility would begin in early 1987 and be completed within two to three years. Modification of this facility would commence in the early 1990s, depending on results of the low-power tests. It is expected that approximately 280 tests would be conducted in a typical year; although more tests may be required, approximately 850 tests per year would be the maximum number that could be conducted. The tests would be conducted at various times during the day and night and would use various ground, air, and space targets. Duration of each test would be a maximum of 60 seconds. Automatic safety mechanisms would abort test firings of the laser if any object greater than 1.0 square centimeter is detected near the laser beam. Ancillary facilities that may be required to support the test and evaluation program include industrial and domestic wastewater treatment systems; stand-by power generation; power, gas, and/or water transmission lines; roads; and railroads. Approximately 500 to 2,500 personnel would be required during the low-power construction phase; 250 to 500 workers would be employed during the operational phase. The No Action alternative would preclude all adverse and beneficial environmental and economic impacts and is still considered as a viable alternative. POSITIVE IMPACTS: The major beneficial effects would be increases in employment and income in the region. Implementation of the proposed project may induce economic development, including higher land values, construction/renovation of schools and recreational facilities, as well as residential and commercial development. NEGATIVE IMPACTS: Direct adverse impacts would include fugitive dust and noise during construction activities; elimination of 2,600 to 3,000 acres of various types of habitat; and total reduction of available habitats for large mammals of 16,000 to 18,600 acres. Significant effects of archaeological/cultural resources could occur. Depletion rates of certain aquifers could be accelerated, depending on the site and alternative water supply selected. Indirect adverse socioeconomic effects would relate to increased demands on schools, law enforcement, recreational facilities, and the emigration of workers from the region after completion of the construction activities.

Preparation date: September 23, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GALVESTON BAY AREA NAVIGATION STUDY AND FEASIBILITY REPORT, GALVESTON AND HARRIS COUNTIES, TEXAS. AN - 36399955; 1010 AB - PURPOSE: Implementation of a plan to improve navigational efficiency on the Houston Ship Channel in Harris and Galveston counties, Texas is proposed. Five comprehensive plans and two combination plans were considered in detail for the final review. All plans studied were developed assuming that Texas City Channel improvements (50 by 600 foot channel from the Gulf to Texas City) are in place. The preferred alternative (Plan HG50) proposes to deepen portions of both the Houston Ship Channel (HSC) and the Galveston Channel to 50 feet, using a combination of existing upland disposal areas and unconfined bay disposal areas. The HSC would be widened from 400 feet to 600 feet as far as Boggy Bayou and from 300 feet to 400 feet at selected reaches between Boggy Bayou and Clinton Island. The Galveston Channel would be deepened across only 450 feet of the width of the existing 1,125 foot channel. The plan also includes buoyed shallow draft auxiliary channels (200 feet wide with no dredging required) on both sides of the Galveston Entrance Channel; bend easing at the intersection of the HSC and the Gulf Intracoastal Waterway (GIWW); improvements to the overall system of aids to navigation; and future maintenance of the improved channels. Dredged material for the landlocked reach of the HSC and the Galveston Bay reach of channel between Five Mile Cut and Morgan's Point would be placed in fully confined upland disposal areas beginning in the vicinity of Atkinson Island. Dredged material from the bay reach south of Five Mile Cut would be placed in seven unconfined open bay disposal areas across Galveston Bay. Material from the Galveston Channel would be placed in the Pelican Island confined upland disposal area. The total first cost of the plan is estimated to be $355 million; annual maintenance costs are estimated at $3.2 million. POSITIVE IMPACTS: Reduced vessel traffic would produce a slight improvement in air quality and a slight decrease in noise. Erosion of existing disposal island area habitat would be halted. The probability of vessel casualties also would be reduced. The improved channel could stimulate growth for oil community growth plans. Increased efficiency of waterborne transport could encourage business to expand and property values along the improved channels would increase. NEGATIVE IMPACTS: There would be a slight potential for impacts to cultural resources along the channel. Unavoidable adverse effects would include loss or disturbance of bay bottom and oyster reefs and increased saltwater intrusion during certain infrequent inflow conditions. Increased turbidity during dredging operations would also occur.

Preparation date: September 19, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED ARCO COAL OIL POINT PROJECT, SANTA BARBARA CHANNEL, CALIFORNIA. AN - 36393750; 967 AB - PURPOSE: Development of oil and gas leases PRC 208, 308, 309, 3120, and 3242 in state waters offshore of the Goleta area in Santa Barbara County, California by Atlantic Richfield Company and its subsidiaries, ARCO Oil and Gas Company (ARCO) and Four Corners Pipeline Company, is proposed. The project would consist of several major components required to produce oil and gas from the leases. They include (1) three offshore platform complexes for drilling and production of oil and gas; (2) an oil processing facility to remove the water and other impurities occurring with the crude oil to be built on the site of the existing Ellwood oil and gas treating facility; (3) a new gas treatment facility to remove water, hydrogen sulfide, and other impurities found in the produced natural gas, which would be constructed at Las Flores Canyon; (4) onshore and offshore pipelines for transport of oil and gas; and (5) storage tanks for processed crude oil, to be constructed at Dos Pueblos South. Although the five leases are located adjacent to one another and are under the control of the same operator, each lease was issued separately and has its own lease terms and royalty formula. POSITIVE IMPACTS: Production from these five leases would generate royalties to the state of California. Also the county of Santa Barbara would receive one percent of the royalty paid to the state. The reserves proposed to be developed by this project constitute an economically significant domestic fossil fuel resource within the continental United States. Additional beneficial impacts would occur in the area of recreation and tourism, with provision of coastal trails and coastal access and creation of artificial marine habitats. NEGATIVE IMPACTS: Adverse impacts include but are not limited to: (1) facility damage due to seismic shaking; (2) increased sediment loads in streams from erosion; (3) damage to or disturbance of marine habitat due to construction of offshore platforms and pipelines; (4) loss of woodlands, riparian areas, and possibly endangered species due to facility and pipeline construction; (5) disturbance to Native American cultural sites during construction; (6) conversion of agricultural lands to industrial use; (7) visual degradation; (8) disruption of commercial and sport fishing; and (9) disruption of research activities.

AN - 36393913; 1007 AB - PURPOSE: Improvement of the channels and turning basin and excavation of a new basin within Fort Pierce Harbor on the Fort Pierce Inlet on the Atlantic coast of Florida are proposed. Fort Pierce Inlet is a man-made opening from the Atlantic Ocean into the Indian River east of the city of Fort Pierce. Under the preferred alternative, the existing entrance channel would be enlarged to a depth of 30 feet and a width of 400 feet. The interior channel would be deepened to 28 feet and widened to 250 feet. The existing turning basin area would be enlarged to 1,100 feet square and 28 feet deep, and an access channel 1,250 feet long, 250 feet wide, and 28 feet deep would be provided immediately north of the existing terminal area. Ocean disposal was selected as the most suitable method for disposing of dredged material unsuitable for placement on beaches. The site selected is approximately 1 nautical mile square, located 5.5 miles east-southeast of the inlet in approximately 50 feet of water. This is the logical choice because it is an historical dumping site for dredged materials and has interim approval from the EPA for this purpose. Beach disposal would be used for dredged material that is suitable in grain size for placement on the beach south of the inlet. All sand would be hydraulically pumped through a pipeline onto the beach and spread with bulldozers. Good quality dredged material from the inner channel would be disposed of by hydraulically pumping it into a deep borrow area south of Causeway Island. This would allow approximately 12 acres of seagrass beds to be created. Most of the excavation would be carried out with a hydraulic suction wedge. Turbidity barriers would be utilized to protect sensitive areas from suspended sediment generated by dredging. The total construction cost is estimated at $6.4 million, with $55,000 annually for maintenance, in addition to amounts now required. Net benefits of the recommended plan would amount to $486,000 annually, with a benefit-to-cost ratio of 1.8. POSITIVE IMPACTS: Enlargement of the channels and turning basin and addition of the new turning basin would enable shippers of current and projected commodities to use deeper draft vessels for transport to the Fort Pierce Harbor tributary area. Navigation improvements would also allow the port to be more competitive with other Florida ports, thereby attracting new business and providing employment opportunities for residents within the area. Fresh citrus, citrus pulp, and aragonite shippers would benefit particularly from the improved harbor facilities. Beach erosion control would benefit sea turtles, and the use of dredged material to develop shallow water habitat would increase wetland acreage in the area. NEGATIVE IMPACTS: Dredging would result in the loss of a portion of worm reef. Shipping within the harbor would continue to pose some hazards to the sea manatee, an endangered species.

AN - 36402619; 993 AB - PURPOSE: Construction of 4.5 miles of highway from the intersection of North Carolina (NC) 280 and NC 191 to Interstate 26 (I-26) in Henderson and Buncombe counties, North Carolina is proposed. The preferred alignment would begin just north of the intersection of NC 280 and NC 191 at Mills River and follow the existing alignments across the floodplain to State Route (SR) 1345. Just north of SR 1345, the road would shift to new alignment and would intersect SR 1351, SR 1354, and SR 3526. The road then would connect with I-26, with a new interchange. The new interchange would retain the existing rest area(s) at I-26. The section of the new facility utilizing the existing alignment would be widened from 64 feet, face to face, curb and gutter section northward from the NC 191 intersection, to include the proposed Mills River bridge. Then the existing 22-foot pavement would be widened to 60 feet with 8-foot usable shoulder widths. This would provide for a five-lane cross-section, with the center lane used for turning traffic. The remainder of the highway would consist of a 24-foot pavement with 8-foot shoulders on adequate rights-of-way reserved for a future four-lane divided highway with a 30-foot grass median. New bridges would be built over the Mills River and the French Broad River. Highway construction costs are estimated at $9.9 million and rights-of-way acquisition costs at $3.4 million. POSITIVE IMPACTS: The new highway segment would reduce travel distance and time to reach I-26, improving access to the Asheville Airport and other sites reached via I-26. Traffic conditions on existing NC 280 and NC 191 would be improved. NEGATIVE IMPACTS: The project would require the taking of 7.3 acres of prime farmland and the relocation of two residences and one seasonally operated fruit stand. Noise levels would exceed federal standards at two residences and one business.

AN - 36399848; 1001 AB - PURPOSE: Homeporting of 27 vessels at eight locations on the U.S. Gulf Coast is proposed. Implementation would be executed in the late 1980s and early 1990s. The proposed strategic homeporting action is composed of three parts: (1) Homeport vessels comprising an aircraft carrier battle group in Pensacola, Florida, Mobile, Alabama, and Pascagoula, Mississippi. These three cities would be assigned 11 ships altogether, including an aircraft carrier, destroyers, cruisers, minesweepers, and frigates. (2) Homeport vessels comprising a battleship surface action group at Corpus Christi /Ingleside and Galveston, Texas. A total of 10 ships would be assigned to these two cities, including the battleship group at Corpus Christi/Ingleside and the Naval Reserve Forces (NRF) ships at Galveston, Texas. (3) Homeport a total of six support vessels at Lake Charles, Louisiana, Gulfport, Mississippi, and Key West, Florida. A total of 27 ships and approximately 10,750 Navy personnel would be located at these eight sites. Dredging of navigation channels or turning basins would occur at six sites. Approximately 31 million cubic yards (MCY) of new work material and 48 MCY of maintenance material would be dredged and disposed of at specified locations over the next 50 years. Waterfront and shore facilities would be constructed to support the homeported vessels. The homeports would be permanent naval facilities. POSITIVE IMPACTS: Existing channel alignments from the Gulf of Mexico into Pensacola Bay and Corpus Christi Bay would be enlarged. Turning basins and berthing areas would be dredged at Corpus Christi, Galveston, Lake Charles, Pascagoula, Mobile, and Pensacola. During construction, a maximum of 5,200 new jobs would be created, resulting in annual income reaching $113 million in 1990. By 1991, when all eight proposed installations become fully operational, more than 20,000 new jobs would be created, 12,000 of which would include the direct assignment of military and civilian personnel to the installations and their homeported ships. These new jobs would bring in approximately $370 million per year in new wage and salary income. NEGATIVE IMPACTS: Topography and bathymetry would be altered during construction, dredging, and dredged material disposal activities. Noise levels would increase adjacent to construction zones. Short-term impacts to water quality would occur due to dredging and dredged material disposal. Turbidity levels would increase in areas adjacent to dredging. Extant vegetation on portions of most of the proposed sites would be eliminated. Wildlife habitat would be adversely impacted. Some wetland areas would be affected by dredged material disposal. Some currently undeveloped areas would be developed for residential and commercial use. In the Ingleside area in particular, a significant increase in new residential units would be needed to house a new population.

Preparation date: August 29, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CENTRAL UTAH PROJECT, BONNEVILLE UNIT, MUNICIPAL AND INDUSTRIAL SYSTEM (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF OCTOBER 1979). AN - 36404955; 1011 AB - PURPOSE: Construction of the Municipal and Industrial (M&I) System of the Bonneville Unit in Salt Lake, Utah, Summit, and Wasatch counties, Utah is proposed. The project would include construction of the Jordanelle Reservoir and associated recreational facilities on the Provo River 38 miles upstream of Utah Lake; completion of the 14-mile Alpine Aqueduct, of which 1 mile is under construction; completion of the remaining 23 miles of the 38-mile Jordan Aqueduct; and modification of 15 upper Provo River reservoirs. Design features of the Jordanelle Dam would include a height of 296 feet, a crest length of 3,110 feet and width of 30 feet, and an outlet works with a multilevel intake structure. Power plant construction will be deferred, awaiting nonfederal participation. The outlet works will be designed to accommodate the convenient addition of a power plant at some future date. The potential to produce 10.4 megawatts will remain. At its total capacity of 320,300 acre-feet, the reservoir would have a surface area of 3,068 acres. The Alpine Aqueduct would consist of 5.0- to 7.5-foot concrete pipe buried at a minimum depth of 3 feet and would transport water treated at the Utah Valley Water Purification Plant. A number of feeder pipelines would connect with existing distribution systems. The Jordan Aqueduct would consist of 4.0- to 6.5-foot concrete pipe and would receive water from the Alpine Aqueduct upstream of the Utah Valley Water Purification Plant for treatment at the Jordan Water Purification Plant. As of January 1986, the Jordan and Alpine Aqueducts were approximately 65 percent complete. The purpose of this supplement is to report and evaluate two types of elements: the environmental impacts of proposed modifications to the M&I System plan and impacts or consultations not previously covered. Proposed actions for which analyses or consultations have been conducted include: (1) relocating U.S. Highway 189 along an alignment different from that described in the final environmental impact statement (FEIS), (2) adding a new Wasatch County road; (3) relocating the outlet works of Jordanelle Dam from the right to the left abutment; (4) adjusting the reservoir management boundary and land for project features; (5) modifying the fishery mitigation/recreation plan between the proposed Jordanelle Reservoir and the existing Deer Creek Reservoir by refining Provo River access requirements and eliminating boating and tubing on the river; (6) modifying the wildlife mitigation plan; (7) evaluating impacts to area wetlands; and (8) consultations with the Fish and Wildlife Service regarding the June sucker, a recently listed endangered species. This supplement also provides a brief update of the status of the M&I System. Since filing of the FEIS, some circumstances have changed, some features have been constructed, and progress has been made relative to commitments made in the FEIS. In addition, this supplement provides compliance for the Army Corps of Engineers 404 permit process. POSITIVE IMPACTS: Potential safety hazards would be reduced by the road relocations. Mitigation would be provided for wildlife habitat losses stemming from road location realignments, changes in the reservoir management boundary, and wetland and riparian impacts not previously covered. The project would provide 90,000 acre-feet of water annually for municipal and industrial use in Salt Lake County and northern Utah County. Delivery of 14,100 acre-feet of supplemental irrigation water annually to 22,740 acres of agricultural lands in the Heber and Francis areas would eliminate current late-season water shortages and would reduce excessive early-season applications to these lands, increasing crop production. Stabilization of 12 of the 15 upper Provo River reservoirs would enhance recreational and fishery values in the Wasatch National Forest. Recreational provisions of the reservoir would accommodate 5,160 visitors simultaneously. NEGATIVE IMPACTS: The reservoir project would result in the displacement of 38 residences, 3 businesses, 3 farms, and a small cemetery, and the impoundment would inundate 3,500 acres of wildlife habitat, including 630 acres of scarce, high-value streamside riparian habitat. Closure of the existing Olmsted power plant would result in a net loss of energy production and the elimination of 14 jobs.

Preparation date: August 28, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GREAT LAKES CONNECTING CHANNELS AND HARBORS: NAVIGATION IMPROVEMENTS, SABIN AND DAVIS LOCKS, SAINT MARY'S FALLS CANAL AT SAULTE SAINTE MARIE, MICHIGAN. AN - 36399926; 1009 AB - PURPOSE: The construction of a new lock on the Saint Mary's River at Saulte Sainte Marie, Michigan, is proposed. The lock would be located in the North Canal of the Soo Locks complex, between the sites of the Sabin and Davis locks, which would be demolished. The lock would measure 115 feet in width by 1,294 feet in length. Depth over sills would be 32 feet. Excavation from the approach channels would be accomplished using clamshell-type dredges, and dredged material would be disposed of at either Northwest or Northeast piers. Water intake for the new lock would consist of eight openings similar to the intake manifold on the Poe Lock. The ports would be located in the wall immediately downstream from the upper dewatering bulkhead recesses. Outlet culverts would discharge the water through five ports on each side of the wall face immediately upstream of the lower dewatering guard gate. A traffic-monitoring system using a 25-foot parabolic antenna would be installed. Sanitary facilities and a coal-fired steam plant would also be constructed. Estimated cost of the project is $226.6 million, and the benefit-cost ratio is 1.41. POSITIVE IMPACTS: The new lock could accommodate the largest vessels currently operating in the U.S. Great Lakes fleet, and would make it possible to space vessels along the river to avoid congestion and vessel encounters in constricted reaches. The new lock system also would allow vessel speeds to be monitored throughout the river, would relieve capacity restraints, and would reduce risks to the shipping industry and national security. Construction activities would generate 100 to 425 jobs. NEGATIVE IMPACTS: The construction of a new lock could result in the use of more 1,000-foot vessels. This could cause additional development at Great Lakes ports to accommodate the larger vessels and put pressure on the Welland Canal and the Saint Lawrence Seaway to also expand to accommodate the larger ships. The Sabin and Davis locks would be demolished, and the surface of the Northeast and Northwest piers would be altered permanently by disposal of dredged material. These areas are part of the Saint Mary's Falls Canal, which is listed as a National Historic Landmark.

Preparation date: August 27, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TOMBIGBEE RIVER AND TRIBUTARIES, LUXAPALILA CREEK SEGMENT, ALABAMA AND MISSISSIPPI (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT, DESIGN MEMORANDUM NO. 2). AN - 36380007; 1002 AB - PURPOSE: The Tombigbee River and Tributaries Project provided for flood reduction measures along 22 streams tributary to the Tombigbee River in northeast Mississippi and northwest Alabama. These measures were to include channel clearing, snagging, enlargement, realignment, erosion protection, and other alternatives that would reduce flood damages and result in land enhancement. This supplemental environmental impact statement (SEIS) is only for the proposed Luxapalila Creek segment of the project, which would result in the reduction of flood damages in Lowndes County, Mississippi and Lamar County, Alabama. The nonstructural component of the selected plan would consist of a flood warning system for the Luxapalila Creek basin, including (1) channel modifications from the upstream limit of the existing channel works at mile 2.1 to Waterworks Road (Highway 50) at mile 6.2, which includes a fabric dam control structure for stream bed stabilization and fish passage and five notched sills and pools for stream fish resource mitigation; (2) selective clearing and snagging of the Luxapalila Creek from mile 6.2 to mile 28.4 near Millport, Alabama, which includes timber management on 550 acres of easement lands between Steens, Mississippi and Millport for partial mitigation of wildlife resource losses; (3) excavation of a diversion channel from the previously modified channel at mile 28.4 to the old stream meander on the right (north) floodplain; (4) excavation of five small lateral channels in the reach between mile 24.6 and 28.4 to aid in alleviating the year-round flooding on the left (south) floodplain; (5) a beaver trapping and dam removal program in the area between Steens and Millport, which would allow trapped water to flow to the old natural stream meanders and lateral channels; (6) construction of a sediment trap immediately downstream (west) of the Alabama Highway 17 bridge near Millport at mile 31.6; (7) acquisition of approximately 700 acres of land in fee and easement for management of wildlife and timber resources; (8) a flood warning system; and (9) acquisition of 150 acres of separable lands near Amory, Mississippi, consisting primarily of bottomland hardwoods, for partial mitigation of wildlife resource losses. Excavated materials would be placed on approximately 32 acres adjacent to these areas. Logs and other debris would be placed on an adjacent bank within the 650 acres of permanent easement land. All work and excavation areas would be seeded immediately after construction is completed to prevent soil erosion. A fabric dam control structure with a capacity to be inflated to elevation 150 feet National Geodetic Vertical Datum (NGVD) would be constructed downstream from Waterworks Road, near the upstream limits of the enlarged channel to ensure stability of the channel upstream of the structure. This dam would be operated only during flood periods; it would be deflated and on the creek bottom during nonflood periods. A grade control structure would be placed at the mouth of Magby Creek to reduce potential head-cutting and degradation of that stream. Riprap would be placed at four highway bridges and two railroad bridges to reduce potential erosion at these bridges. For the reach between mile 2.1 and mile 6.2, a system of low dikes, swales, and overbank drainage structures would be provided along the disturbed bank to protect it from erosion caused by overbank flows. The total project first cost for the selected plan is $12.6 million. The total average annual costs are $1.4 million, and the average annual benefits are $1.9 million, for a total benefit-to-cost ratio of 1.4. POSITIVE IMPACTS: Construction of the project would reduce flood damages in both Mississippi and Alabama. In Mississippi, reduced flooding would improve the quality of life for many residents of the city of Columbus, alleviating the fears and uncertainties associated with frequent floods. Also, property values might increase with reduction in the frequency of flooding. In Alabama, land would return to a productive state. A recurring mosquito problem would be greatly reduced with the removal of the shallow, stagnant water areas, thereby reducing the incidence of malaria that has occurred in the area in the past. Recreational opportunities would also improve as habitat for wildlife improves and as areas become more accessible. NEGATIVE IMPACTS: Approximately 4.1 miles of Luxapalila Creek would be modified as a result of channel enlargement, as well as approximately 0.5 miles of creek by construction of the diversion channel and sediment trap. Approximately 22.2 miles of natural channel would be modified by selective clearing and snagging operations. A maximum of 19.0 acres could be adversely affected by access routes for construction equipment. Collectively, these actions would adversely affect fish, benthic, macroinvertebrate, and aquatic organisms in the construction areas and in the areas from which the year-round flooding is alleviated. Approximately 8.17 acres of creek habitat would be destroyed, disturbed, or otherwise affected, and approximately 334 acres of wildlife habitat would be disturbed. Some 34.4 acres of wetlands would be filled, and 12 acres of prime farmland would be lost.

AN - 36394222; 955 AB - PURPOSE: Construction of the 642-acre West Beach resort complex, which includes housing, boating, and recreational features, in Honouliuli of the Ewa District on the island of Oahu, Hawaii is proposed. The final supplement to the final environmental impact statement of September 1980 has been refocused to define and address those actions that fall within the scope of Corps of Engineers permit authority, namely construction of the marina and the bathing beach lagoons. If the project is fully realized as planned, the development would include 4,000 hotel-condominium units on 86.3 acres, 5,200 residential units on 186.2 acres, 17.8 acres of commercial development, a 33.9-acre marina with 500 berths and supporting facilities, an elementary school on 6.9 acres, a 171.3-acre golf course, a 1.9-acre beach club, 46.8 acres of parks, a 21.8-acre cultural center, a 13.1-acre lagoon system, four bathing beach lagoons, and 47.9 acres for a circulation system and transit stations. Power would be transmitted to the development via two 46-kilovolt transmission lines. Estimated cost of the project in 1980 dollars is $1.1 billion. This informational supplement includes: (1) The fully executed Memorandum of Agreement (MOA) on the cultural/archaeological aspects of the project. (2) Comments from reviewers. (3) The Public Notice informing the public that a water quality certification or waiver of certification is required from the Hawaii Department of Health prior to issuance of a Department of the Army permit under Section 404 of the Clean Water Act. POSITIVE IMPACTS: The project would provide living accommodations, recreational benefits, and employment for numerous persons. Development features would include creation of 47 acres of aquatic habitat. NEGATIVE IMPACTS: Approximately 75 acres of terrestrial wildlife habitat would be inundated, and 266 acres of prime farmland and 133 acres of other important agricultural lands would be converted to urban uses. The development would require 4.5 million gallons per day (MGD) of water and would generate 2.5 MGD of sewage effluent. Dredging along the shoreline and within the entrance channel would destroy coral resources in limited areas. All residents would be exposed to aircraft noise, and some residents living in the vicinity of Farrington Highway would be exposed to highway noise levels in excess of Department of Housing and Urban Development standards. Marina and lagoon development would influence local water quality along the coast, and infiltration would introduce brackish water and nutrient-laden water into the aquifer, possibly violating federal water quality standards. Archaeological sites would be disturbed and destroyed, and a colony of rare plants would be destroyed by marina and golf course development.

Preparation date: August 19, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED NORTH CORRIDOR ARTERIAL, US 12 TO US 53, EAU CLAIRE COUNTY, WISCONSIN (FEDERAL NUMBER M-2800( ), PROJECT I.D. 7995-00-99). AN - 36387297; 952 AB - PURPOSE: Construction of a new controlled-access urban arterial and a Chippewa River crossing in the northern part of the city of Eau Claire, Eau Claire County, Wisconsin is proposed. The project would begin near the intersection of USH 12 (Clairmont Avenue) and USH Business 12 (Truax Boulevard) and would extend easterly approximately 4.7 miles to connect with USH 53 (Hastings Way). The specific design configuration for the connection to USH 12 has not as yet been selected. In addition to the No Build Alternative, three alternatives were considered: (1) The LaSalle Alternative, which would begin near the intersection of USH 12 and USH Business 12 and would follow an easterly direction to CTH T. A probable new interchange would ultimately be constructed in the area located between CTH T and Jeffers Road, generally bounded by the Chicago and NorthWestern Railroad tracks on the north and the Northern State Power transmission lines on the south. A number of interchange configurations could be considered. (2) The Marquette /Hiawatha Alternative would be identical to the LaSalle Alternative from USH 12 to Gessner Road; just east of Gessner Road, it would be directed northeast across the Chippewa River to Riverview Drive, where it would curve slightly to the southeast to intersect with Hiawatha Street at Starr Avenue and proceed east on Hiawatha Street to a new interchange with USH 53. (3) The LaSalle/Hiawatha Alternative is a combination of the LaSalle and Marquette/Hiawatha alternatives. It would be identical to the LaSalle alignment from USH 12 to Wander Court and would be identical to the Marquette /Hiawatha alignment from Starr Avenue to USH 53. The alignment between these sections would be directed in a northeast direction from Wander Court to Starr Avenue. All three build alternatives would include a new Chippewa River crossing; all would also have similar typical street sections. A modified urban section, based on Design Class A-3 standards, would be used west of the river. This segment would have an average 180-foot right-of-way, two 12-foot driving lanes in each direction, a grass median, 10-foot wide outside shoulders, and a ditch section on both sides. Roadway constructed east of the Chippewa River would have an urban type section, based on Design Class U-4 standards. This segment would have an average 120-foot right-of-way, two 12-foot driving lanes in each direction, a grass median, and sidewalks on both sides. The LaSalle Alternative would cost approximately $25.4 million; the Marquette/Hiawatha Alternative would cost approximately $25.2 million; and the LaSalle/Hiawatha Alternative would cost approximately $24.3 million. POSITIVE IMPACTS: The project would serve an identified need for a new river crossing and a connecting link between the northwest and northeast quadrants of the city. All of the build alternatives would improve access to the Eau Claire County Airport and between DeLong Junior High School and North High School. All areas recommended for future development would be served, and travel distances, travel times, and vehicle fuel consumption would be reduced. NEGATIVE IMPACTS: Adverse impacts would include the acquisition of 43 to 49 residences and 2 to 4 businesses. Noise levels would increase in residential areas. All build alternatives would encroach on 5.2 to 6.2 acres of floodplains, and 16.5 to 17.2 acres of trees or woodlands would be lost. Aesthetic qualities would be affected by the roadway and new river crossing. Approximately 0.3 acres of wetlands would be affected by the Marquette/Hiawatha Alternative; no wetlands would be directly affected by either of the other alternatives. All the build alternatives would result in short-term construction impacts to air quality, noise, traffic flow, and water quality.

Preparation date: August 18, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED US 24 LOGANSPORT BYPASS, CASS AND MIAMI COUNTIES, INDIANA: PROJECT F-144-3(1), F-144-5(1), and F-144-6(1). AN - 36385669; 943 AB - PURPOSE: Relocation of 14.7 miles of U.S. 24 in Cass and Miami counties, Indiana is proposed. The newly aligned, dual-lane facility would extend from U.S. 35 at Logansport on the west to the interchange between U.S. 24 and U.S. 31 northeast of Peru. The proposed facility would consist of a four-lane divided roadway with a 60-foot median and a rights-of-way width of 290 feet. Partial access control at existing county and state road intersections would be provided. Total estimated costs for the project are $50.7 million. POSITIVE IMPACTS: Relocation of U.S. 24 would reduce the accident rate, noise levels, and air pollution within the city of Logansport. Jobs would be created during the construction period. Access to recreational areas and to Grissom Air Force Base, as well as access of fire and police vehicles to rural areas, would improve. NEGATIVE IMPACTS: Rights-of-way land requirements would be 393 to 582 acres of primarily rural farmland. Twelve residences and one business would be relocated. Travel-oriented businesses along present U.S. 24 probably would suffer losses in trade. Noise levels would increase and air quality would diminish in the area of the relocation. Wildlife habitat also would be disturbed.

Preparation date: August 15, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED WEST DESERT PUMPING PROJECT, GREAT SALT LAKE, UTAH. AN - 36398407; 962 AB - PURPOSE: Construction of a pumping plant and associated canals and dikes to create evaporation ponds in the west desert to the west of the Great Salt Lake (GSL) in Box Elder and Tooele counties, Utah is proposed. The primary purpose of the West Desert Pumping Project would be to lower the level of the GSL, reducing or controlling flooding of the lake. The proposed action involves construction of several structures in the area west of the GSL. This final environmental impact statement discusses the modified, "Bare Bones," version of the project, some portions of which are still being designed. A pumping station would be located adjacent to, and on the south side of, the Southern Pacific Railroad grade on Hogup Ridge. Water would be pumped directly from the north arm of the lake, although canals may need to be dredged as the lake recedes. A trestle would be constructed so the water could flow under the railroad grade from north to south to the pumping station. The pumping station would utilize three pumps, designed to pump up to 3,500 cubic feet of water per second up approximately 23 feet to a discharge channel. Although originally planned to be diesel powered, present plans call for the pumps to be powered by natural gas. The discharge channel would transport the water to the north side of the railroad grade near the northern end of the Newfoundland Mountains. The water would then spread out and move south under the railroad grade and along the west side of the Newfoundland Mountains. The Bonneville and Newfoundland dikes would contain the pond. The Bonneville Dike would keep the pond, called the West Pond, from covering I-80 and from flooding the Bonneville Salt Flats. The Newfoundland Dike would extend from the southern end of the Newfoundland Mountains southeasterly to high ground across the mud flats. A control weir in the Newfoundland Dike would maintain the maximum level of the West Pond at elevation of approximately 4,217, and at a size of approximately 320,000 acres. Water would flow over the weir in the Newfoundland Dike and then by the lay-of-the-land back to the north arm of the lake, resulting in scattered ponding in low areas between the Newfoundland Mountains and the North Arm. The water would flow under the Southern Pacific Railroad grade via a trestle to be built for the project near Lakeside. The project would cost approximately $55 million to build, and construction would take approximately one year. The work force would not exceed 200 persons. POSITIVE IMPACTS: Kaiser Chemical might be benefited by increased brine flow caused by groundwater recharge from the West Pond. The lake would essentially not rise from present levels, creating significant flood control benefits to shoreline areas. All sectors would be benefited, especially the transportation sector. The wetlands, farmlands, and cultural resources would be protected. A major benefit would be the drying out of areas presently flooded. NEGATIVE IMPACTS: During winter months, there would be an increase in winter fog around the GSL and an increase in precipitation along the Wasatch Front. This would impact the Air Force operations on the Utah Test and Training Range. Also, the West Pond would restrict flight operations, because Air Force regulations do not allow low-level flights over open water.

Preparation date: August 13, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LEE CREEK WATER POWER PROJECT, FERC PROJECT NO. 5251, CRAWFORD AND SEBASTIAN COUNTIES, ARKANSAS AND LEFLORE AND SEQUOYAH COUNTIES, OKLAHOMA. AN - 36403655; 923 AB - PURPOSE: The city of Fort Smith, Arkansas is proposing to construct and operate a hydroelectric project, with an installed capacity of 1.5 megawatts (MW), to be located approximately 2.5 miles north of Fort Smith on Lee Creek at river mile (RM) 3.2. The power project would consist of: (1) an ogee dam, approximately 1,000 feet long and 34 feet high; (2) a 634-acre impoundment; (3) a powerhouse with an installed capacity of 1.5 MW; (4) a 12.5 kilovolt (kV) primary transmission line extending approximately two miles to connect with the local power system; and (5) other appurtenant facilities. An existing, nonproject 161-kV transmission line would be rerouted 2.5 miles around the impoundment. In addition to generation of electricity, the proposed project would supply water to the city of Fort Smith. Water supply features would include: (1) the impoundment, (2) a 3-stranded barbed wire fence enclosing a 300-foot buffer zone around the impoundment, (3) raw water intake, (4) a water treatment plant with a hydraulic capacity of 139 cubic feet per second, and (5) a five-mile-long water transmission line to Fort Smith. POSITIVE IMPACTS: The project would provide a short-term (approximately 10 years) solution to anticipated water shortage problems and would boost the growth potential of cities and towns that now depend on or are attempting to use the Fort Smith water systems. NEGATIVE IMPACTS: Water use rates would more than double for every user category by 1987. The proposed action would have a substantial impact on significant cultural resources in the Lee Creek area. Adverse effects to archaeological and historic sites include inundation, erosion, and vandalism. At least 11 sites would be subject to direct or indirect impacts. There is potential for the mass movement of soils in the vicinity of the dam site as a consequence of project construction activities. Land use changes related to construction of the proposed reservoir would entail inundation of approximately 292 acres of forestland, 233 acres of pastureland, and 5 acres of an existing transmission line right-of-way. Impoundment of Lee Creek and the establishment of a 300-foot buffer zone around the reservoir would result in the loss of potential use of 750 acres of prime farmland. During the construction period, noise would affect 5 to 18 residences. The most important impact of the proposed project on terrestrial communities would be the loss of 530 acres of wildlife habitat by inundation. Existing populations of semiaquatic animals would probably be eliminated or greatly reduced as a result of fluctuations in water levels. Longnose darters would be adversely affected as a result of direct habitat loss and some indirect effects.

Preparation date: August 8, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COYOTE CREEK FLOOD CONTROL PROPOSAL, SANTA CLARA COUNTY, CALIFORNIA. AN - 36400473; 957 AB - PURPOSE: Construction of flood control facilities on Coyote Creek in the southern San Francisco Bay region, California is proposed. The project would be constructed in the cities of San Jose and Milpitas, extending along Coyote Creek for a distance of approximately 6.5 miles. The project area is divided into three reaches: Reach 1 begins at the Southern Pacific Transportation Company railroad bridge near Drawbridge and ends at the Milpitas Pumping Station; Reach 2 extends from the Milpitas Pumping Station to Highway 237; Reach 3 starts at Highway 237 and terminates at Montague Expressway. A bypass channel is planned for Reach 1, which would require limited excavation near its upstream terminus. The channel would follow the existing Coyote Slough around the southern side of Newby Island. Earthen levees would be constructed on both sides of the bypass channel, and a retaining wall would be installed close to the end of the reach. An excavated, earthen overflow channel would be constructed in Reach 2 and Reach 3. The overflow channel would be situated on the floodplain adjacent to the existing Coyote Creek channel and would cross the stream in several locations. These crossover locations would be lined with riprap. Concrete- and rock-lined sections would be necessary under the Highway 237 and Montague Expressway bridges, respectively. Earthen levees and a relatively short section of floodwall are proposed to help contain flood-flows in the overflow channel. POSITIVE IMPACTS: The proposed project conforms with the established goal of providing communities with protection from serious flooding. Implementation would result in far less maintenance-related clearing of vegetation in the Coyote Creek streambed. Over the long term, this would permit natural succession to occur without interruption, thereby benefiting the quality of instream riparian habitat. NEGATIVE IMPACTS: The following impacts would be partially offset through a mitigation program. Approximately 21 acres of a salt evaporation pond, used by numerous bird species for foraging and resting, would be eliminated. Approximately 1,850 riparian trees (nearly 15 percent of existing trees along Coyote Creek) would be removed at various locations, resulting in 18 permanent breaks in the continuity of the riparian corridor. These breaks would reduce wildlife diversity by eliminating species unable to maintain their populations due to migration barriers. In addition, small animals, reptiles, amphibians, and nesting birds would be lost due to construction operations. The visual quality of the creek would be adversely impacted. Implementation of the preferred alternative would require a commitment of 345 acres for rights-of-way. At least one occupied house, a packing-shed facility, and an undetermined number of structures, some historically significant, would be relocated.

Preparation date: August 8, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RECONSTRUCTION OF I-680/SR 24 INTERCHANGE AND FREEWAY IMPROVEMENTS BETWEEN RUDGEAR ROAD IN WALNUT CREEK AND WILLOW PASS ROAD IN PLEASANT HILL/CONCORD IN CENTRAL CONTRA COSTA COUNTY, CALIFORNIA. AN - 36400690; 941 AB - PURPOSE: Reconstruction of the I-680/SR 24 interchange and freeway improvements between Rudgear Road in Walnut Creek and Willow Pass Road in Pleasant Hill/Concord in central Contra Costa County, California are proposed. The purpose of the project is to eliminate the worst bottleneck in the entire 71-mile length of the I-680 bypass of the Metropolitan Bay Area by upgrading its substandard interchange with SR 24 in Walnut Creek and correcting a number of interrelated operational problems that also contribute to congestion in the project area. The I-680/SR 24 interchange would be reconstructed to provide three through lanes on all freeway-to-freeway connectors, widen I-680 from six to eight through lanes within the project limits, and add auxiliary lanes where needed. In order for the improved interchange to be functional, the following improvements would also be required: (1) modify the South Main Street interchange; (2) remove the Newell Avenue ramps and construct a full (loop or diamond) interchange at Olympic Boulevard to service I-680 only; (3) reconstruct the ramps at Ygnacio Valley Road with a direct on-ramp connection to southbound I-680 and westbound SR 24; (4) relocate North Main Street between Oak Park and Contra Costa boulevards; (5) add a southbound off-ramp to Monument Boulevard; (6) add on-ramps to southbound I-680 from Gregory Lane and Monument Boulevard; and (7) add a collector road for the Gregory Lane off-ramp and the new off-ramp to Monument Boulevard in Pleasant Hill. The proposed action would cost approximately $214 million in 1985 dollars ($170 million for construction, plus $44 million for rights-of-way acquisition). POSITIVE IMPACTS: Primary beneficial impacts would be improved freeway operations and accident reduction. The project is considered growth inducing, to the extent that the proposed I-680 improvements would facilitate new development. Air quality would improve as a result of the increased efficiency of combustible fuel consumption. Noise levels would also be generally reduced if all the recommended noise barriers are constructed. NEGATIVE IMPACTS: The proposed project would require displacement of 80 to 103 single-family residences, 69 to 73 multiple-family units, and approximately 25 nonresidential establishments. The maximum parking displacement is estimated at approximately 340 spaces in Walnut Creek and 525 spaces in Pleasant Hill, all of which would be mitigated. If the noise barriers were constructed, the visual quality of the road would be substantially reduced. The major construction impacts would be temporary controllable noise, loss of parking spaces, and occasional lane and ramp closures during nonpeak hour traffic.

Preparation date: August 6, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CUCHILLO DAM, RIO GRANDE FLOODWAY, TRUTH OR CONSEQUENCES UNIT, SIERRA COUNTY, NEW MEXICO. AN - 36398779; 960 AB - PURPOSE: Implementation of a plan to provide increased flood protection to the Truth or Consequences and Williamsburg areas in Sierra County, New Mexico is proposed. The preferred flood control alternative is the Cuchillo Dam (Dam Site Number 2), located approximately three miles downstream from the village of Cuchillo in a canyon locally known as "the box." The dam would control approximately 90 percent (325 square miles) of the 360 square mile Cuchillo Negro watershed. It was determined that a structure consisting of an earthfill embankment nonoverflow section with an off-channel emergency spillway would be the most cost beneficial to build. The dam would form a reservoir approximately 2.3 miles long with water at the spillway crest. Of the total capacity of 13,500 acre-feet (ac-ft), 7,500 ac-ft would be for flood control and the remaining 6,000 ac-ft would be allocated for sediment storage. The spillway crest is at elevation 4,721.4 feet NGVD (National Geodetic Vertical Distance). At the maximum water surface elevation, the reservoir would have a capacity of 20,500 ac-ft and a total flood pool surface area of 520 acres. The nonoverflow section would consist of a roller-compacted concrete portion located in the main canyon and rising 119 feet above the existing streambed. The downstream face would have a slope of 0.8 foot horizontal to 1.0 foot vertical. The earthfill embankment would be a zoned section having a 12-foot wide crest and 3.0 foot horizontal to 1.0 foot vertical sideslopes. An ungated outlet would be incorporated into the structure to pass flood flows through the reservoir without exceeding safe channel capacities downstream. The 73-foot high reinforced concrete intake tower of the outlet works would have a trash rack to prevent large debris from entering the conduit and restricting flows or damaging the structure. The outlet conduit would be 111 feet long, with a stilling basin for a terminal energy dissipator located at the downstream end. The estimated first cost of the Cuchillo Dam Reservoir is $14.6 million, and the annual charges are estimated at $1.5 million. The benefit-to-cost ratio is 1.7. POSITIVE IMPACTS: The recommended plan would alleviate most of the hazards related to the flood problem. It would improve the quality of the water entering the Mim's Lake area and the Rio Grande by removing large percentages of the silt borne by flood waters. The increase in riparian habitat would benefit wildlife. A detention dam on the Cuchillo Negro would reduce the amount of silt entering the Mim's wetland during floods, thereby extending the life of the wetland. The flood control measures would double the life of the marsh to approximately 200 years. A reduction of silt and sediment into the Rio Grande, resulting from the detention dam on the Cuchillo Negro, would benefit the fishery and lengthen the life of the Caballo Reservoir down river. Deposition of sediment may enhance vegetation growing in the flood pool area, which in turn would benefit wildlife habitat. If wildlife numbers were to increase, then the potential for more or better quality hunting also would increase. Mitigation of archaeological sites would produce important data for a relatively unknown portion of New Mexico. Significant geological and paleontological resources discovered within the project site would be excavated and documented. NEGATIVE IMPACTS: Windmills and other structures would have to be removed from the flood pool area because of possible obstruction of the dam's drain conduit. Nine residences in the Cuchillo Negro arroyo would have to be relocated; land required for the project area would have to be acquired by the local sponsors. Agricultural and residential land uses within the project area would be curtailed.

AN - 36399798; 961 AB - PURPOSE: Modification of the Guadalupe River-Channel through Calhoun and Victoria counties, Texas is proposed to improve the navigability of the waterway. The river flows through the Golden Crescent region. The channel would be deepened from 9 to 12 feet and widened from 100 to 125 feet. The dredging project would extend from the channel's origin at the Gulf Intracoastal Waterway to a turning basin at channel mile 34.6. The channel alignment would remain as is in the reach extending through Guadalupe Bay, with symmetrical widening to be performed on either side. Channel widening along landlocked reaches would be done primarily on the southwestern side of the channel. Dredged materials would be disposed of in a combination of bay and upland areas. The project, however, would include construction of a 60-acre diked disposal area in San Antonio Bay for disposal of contaminated spoil; the disposal area would include features to allow for creation of a bird rookery and wetland. Estimated cost of the project is $23.3 million, and the benefit-cost ratio is estimated at 1.2 POSITIVE IMPACTS: Enlargement of the capacity of the channel would create a safer, more efficient means of transporting goods through the area. Environmental features of the plan would preserve 400 acres of bay bottom and create wetland and waterfowl habitat. Transportation savings resulting from the project would amount to $2.9 million per year. NEGATIVE IMPACTS: Disposal of dredged materials would impact 605 acres of upland and 127 acres of bay bottom. Dredging would cause temporary turbidity within the river and bay.

The evolution has been toward packaged programs that perform a variety of computation options, often with a choice of methods. Two examples are the flood runoff computation options of the HEC-1 Flood Hydrograph Package (HEC, 1981) and the variety of capabilities in the HEC-2 Water Surface Profile Program (HEC, 1982). The increased speed and memory available on the microcomputer makes these programs practical to use in this environment. Now that these batch programs have been converted for use on micros, what new developments are underway and what might be the next direction for new computer programs? The Center's current program development for flood control, with an emphasis on water surface profile computation, is presented. JF - Technical Papers.

AN - 36393710; 963 AB - PURPOSE: Implementation of a plan to control ice jam flooding problems on the Missisquoi River in the village of Richford, Vermont, located approximately 47 miles above the mouth of Lake Champlain, is proposed. The preferred alternative would provide for an ice retention structure, consisting of a concrete gravity, low-overflow dam located 750 feet upstream of the Main Street Bridge, and limited channel improvements and modifications in the vicinity of the pilot channel. The dam would be an agee weir, 15 to 17 feet high, with a crest elevation at 442.2 and length of 215 feet. The base width would be 30 feet. At the heel, there would be a 5-foot cutoff to control seepage under the dam that would provide resistance to sliding and overturning. At the toe, there would be a key extending three feet below the base of the dam, which would also control seepage and prevent undermining of the dam. Downstream of the dam, for a distance of 40 feet, there would be a concrete apron with a stepped endsill. The abutment walls would be centilevered concrete retaining walls that would extend to the 100-year flood stage adjacent to and upstream of the dam. The upstream abutment walls would be flared to provide converging flow over the spillway. Draining the dam would be accomplished by a 10-foot-wide stoplogged drain gate. A fish ladder would be added to the project as a mitigation measure. The channel modification would consist of raising the weir into the pilot channel to elevation 430.0 and filling in the left bank to narrow the main channel, as well as raising the pilot channel weir, which would involve the placement of 11,000 cubic yards of common fill, 765 cubic yards of 18-inch riprap, 255 cubic yards of gravel riprap filter, and 4,500 square yards of seeding, fertilizing, and mulching to establish a vegetative cover over the fill. A 700-foot long access road would be constructed from the north along the right side of the river. Provisions for a proposed powerhouse would be adjacent to the dam at the right abutment and would be constructed concurrently with the right abutment wall. The estimated first cost of the dam with minor channel modifications would be approximately $1.7 million. POSITIVE IMPACTS: Approximately 14 acres of land within the 100-year floodplain would be acquired as flowage easement. Erosion impacts downstream would be reduced. Flood protection would have a positive impact for the downtown Richford historical district. Estimated annual benefits for the flood control project are estimated at $165,000. NEGATIVE IMPACTS: Project construction would cause unavoidable increases in turbidity and sedimentation and would temporarily disturb wildlife in the area. Long-term impacts to water quality may occur as a result of changes in river flow and bottom substrate. Short-term impacts to indigenous aquatic organisms would include injuries or mortalities from blasting, excavation, and turbidity. Physical changes in the nature of the river would adversely affect aquatic organisms in the river. The physical barrier presented by the dam would include disruptions in migration patterns of fish for spawning, feeding, age class distributions, and temperature regulation.

AN - 36396636; 896 AB - PURPOSE: Construction of the fully access-controlled Woonsocket Industrial Highway/Route 99, located in the towns of Lincoln, North Smithfield, Woonsocket, and Cumberland, Rhode Island, beginning near the interchange of I-295 and proceeding north to the Route 146 /Route 146A merge and connecting to Route 122 (Mendon Road) Road is proposed. The draft supplement evaluates the impacts associated with three alternative alignments. The alternatives considered include construction of a four-lane limited access roadway along three alternative alignments. All the alternatives involve a transportation network linking the Route 146/I-295 interchange to Route 122 (Mendon Road) in the vicinity of the Woonsocket /Cumberland town line. The three limited-access alignments are Alignments 2, 3, and 4B; they are 4.2, 3.6, and 3.3 miles long, respectively. Alignments 2 and 3 originate at the Route 146/I-295 interchange and proceed north along existing Route 146. Alternative 4B originates from Route 146 immediately north of the I-295 interchange and parallels Crookfall Brook. All alignments provide for a four-lane divided roadway facility with variations, due to frontage road design and median widths. All alignments have been designed to operate at acceptable levels of service. Roadway construction costs (excluding rights-of-way) have been calculated to be $39.9, $41.4, and $36.0 million, respectively. POSITIVE IMPACTS: Implementation of the project would result in significant improvements to the transportation network and would stimulate economic growth in this area of the state. NEGATIVE IMPACTS: The following displacements associated with the three alignments would result. Alignment 2: 33 residential and 17 commercial; Alignment 3: 27 residential and 17 commercial; and Alignment 4B: no displacements. The proposed projects would affect 16.2 acres of wetlands for Alignment 2, 5.3 acres for Alignment 3, and 7.2 acres for Alignment 4B. Implementation of Alignments 2 and 3 would create adverse impacts to the North Smithfield commercial areas along Route 146. Alignment 2 would have an adverse effect on the Blackstone Canal Historic District; Alignment 3 would have an adverse effect on the Smithfield Road Historic District and the Blackstone Canal Historic District; and Alignment 4B would have an indirect adverse visual effect on the Blackstone Canal Historic District.

Preparation date: July 25, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SEARS ISLAND DRY CARGO TERMINAL AND ACCESS ROAD, SEARSPORT, WALDO COUNTY, MAINE: PROJECT RS-0252(3). AN - 36403553; 894 AB - PURPOSE: Construction of a new marine dry cargo terminal with both rail and highway access on Sears Island, located in Searsport, Waldo County, Maine, is proposed. The terminal would be built on approximately 50 acres along the western shore of the new undeveloped 940-acre island. Fully developed, the preferred design would include a 35-acre marginal wharf with up to six ship berths. Shoreside facilities would include an administration building, storage areas, on-site sanitary waste treatment, and parking. The terminal would handle both biobulk (e.g., wood chips, lumber, wood pulp, and potatoes) and containerized cargoes. Development of the facility would require the completion of a new 2.3-mile two-lane secondary highway and a 1.5-mile railroad spur. In the preferred design, access from the mainland would be provided by a 1,200-foot solid fill causeway. POSITIVE IMPACTS: The project would provide transportation cost savings to Maine-based industries, especially the forest product industry, through reduced overland travel distances to a port. It would generate both direct and indirect jobs and other economic activities within Maine that are related to import-export traffic and Maine-based industries. State investments in port facilities would be targeted where new jobs and economic activity is most needed. The primary socioeconomic impacts of the project include 1,970 person-years of employment during full construction of the pier, creation of 219 permanent jobs, an additional $7.4 million in personal income, increased municipal revenues of approximately $51,000 annually and state revenues of $636,000 annually, and transportation cost savings of $1.3 million per year. Secondary impacts would include 1,400 person-years in construction employment, up to 2,750 new jobs, an additional $56 million in annual wages and salaries, up to 560 new residents in Searsport, and approximately $3 million in new state revenues and $2.3 million to $2.5 million in local revenues. NEGATIVE IMPACTS: The project would create permanent losses of marine and upland wildlife habitat and local disruption of the marine bottom (benthic) environment during the large-scale dredging and spoil disposal that would be required. When fully developed, the marginal wharf would cover approximately 33 acres of intertidal and subtidal marine habitat. An additional 58 acres would have to be disturbed for the dredging required to connect the existing channel to the ship berths planned. Site preparation and construction of the terminal would virtually eliminate the 40 acres of upland habitat now existing on the site. Construction of the highway and rail access would result in the direct loss of an additional 12 acres of wildlife habitat, and the causeway would require the filling of approximately 3.7 acres of intertidal marine habitat. Secondary impacts would include an additional loss of up to 12 percent of the island's upland wildlife habitat, a 28 percent increase in traffic on Route 1, and some loss of the visual quality of the island.

Preparation date: July 14, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FEASIBILITY REPORT FOR THE WEST BANK OF THE MISSISSIPPI RIVER IN THE VICINITY OF NEW ORLEANS, LOUISIANA. AN - 36402415; 911 AB - PURPOSE: The feasibility of providing hurricane surge protection to that portion of the west bank of the Mississippi River in Jefferson Parish between the Harvey Canal and Westwego and down to Crown Point, Louisiana is presented. The study includes the parishes of St. Charles, Jefferson, Orleans, and Plaquemines. The preferred alternative would provide for a combination of improving existing levees and constructing floodwalls and new levees along an alignment that includes the West Jefferson Levee District 404 permitted alignment, from the Westwego area in the vicinity of Bayou Segnette to the V-levee in the vicinity of Highway 45 north of Crown Point. The alignment in that reach generally follows existing levees or the wetland-upland interface in areas where no levees currently exist. From Highway 45, the proposed levee would follow the existing V-levee alignment to the vicinity of the Estelle Pumping Station. Because of economic considerations and geotechnical engineering requirements, it would be necessary to enlarge the existing V-levee along a strip of land approximately 155 feet wide where the required levee height is elevation 9.5 feet National Geodetic Vertical Datum (NGVD), and approximately 190 feet wide where the required levee height is elevation 12.0 feet NGVD. From the Estelle Pumping Station, the levee would follow the Harvey Canal-Bayou Barataria Levee to the Harvey Pumping Station. From that point, a floodwall is proposed to tie back into the Harvey Lock. The first cost of the preferred alternative is estimated at $61.5 million, and average annual costs are estimated at $10.5 million, including $50,000 for operation and maintenance and $354,000 for fish and wildlife. Average annual benefits are estimated at $31.8 million. The benefit to cost ratio is 3.04. POSITIVE IMPACTS: Implementation of the proposed plan would provide protection to the West Bank between Westwego and the Harvey Canal north of Crown Point. Mitigation of significant environmental losses is recommended through measures designed primarily to improve the conditions of fish and wildlife habitat in the Jean Lafitte National Park, adjacent to the area that is to be provided hurricane protection. NEGATIVE IMPACTS: The proposed plan would result in the conversion of 841 acres of wildlife habitat to levee and borrow areas. Approximately 33 acres of National Park lands and 59 acres of the EPA-designated Bough aux Corpes 404c area would be directly impacted and converted to levees.

Preparation date: July 14, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ROUTE 265, DANVILLE EXPRESSWAY FROM 0.082 MI. N. ROUTE 58 TO ROUTE 29 (NORTH OF BLAIRS), PITTSYLVANIA COUNTY, DANVILLE, VIRGINIA (STATE PROJECT 6265-071-102, PE100, FEDERAL PROJECT F-045-1(111)). AN - 36399357; 898 AB - PURPOSE: Completion of the final section of the Route 265 Danville Expressway, located primarily in Pittsylvania County with a short section located in the city of Danville, from Route 58 approximately one mile east of the Danville city limits to Route 29 north of Blairs is proposed. Two alternatives are under consideration for the proposed project. Each alternative would include a typical section of two 12-foot travel lanes in each direction, separated by a 60-foot and a variable median and constructed on a minimum 180-foot right-of-way. Varying in length from 8.7 (A) to 8.9 (B) miles, both alternatives have common beginning points and termini. Both alternatives begin 0.082 miles north of Route 58 and traverse in a northerly direction passing just east of the intersection of routes 360 and 732. Here, the alternatives proceed nearly due north, then separate at a point just north of the proposed Fall Creek Spur. Alternative A proceeds across Route 695 before turning in a northeast direction crossing Route 721 just west of its intersection with Route 695, crossing Route 719 west of its intersection with Route 29, and crossing Route 726 just west of its intersection with Route 29. Alternative B turns in a northeast direction, staying to the east of Routes 695 and 719, and crossing Route 1004 just east of its intersection with Route 719. Alternatives A and B become common again from just south of Route 726 to Route 29 near the Faith Home for Children. In connection with the proposed expressway, the department is proposing three short extensions or relocations: the relocation of Route 360, Franklin Turnpike Extension, and Fall Creek Spur. Interchanges along Route 265 are proposed at Route 29, Route 726, Franklin Turnpike Extension, Fall Creek Spur, and Relocated Route 360. Additionally, an interchange is proposed at Fall Creek Spur and Route 29, and an at-grade intersection is proposed at Franklin Turnpike Extension and North Main Street. Estimated costs would be $84 million (A) and $83 million (B). POSITIVE IMPACTS: This project will be the final link in the Route 265 Danville Expressway that is currently under construction. Traffic volumes on major downtown thoroughfares in the city of Danville in design year 2005 would approach acceptable levels of service. The proposed facility would provide a through route for persons wishing to decrease travel time on the north-south Danville corridor and would improve access to the Danville Municipal Airport. Additionally, movement of emergency and rescue equipment in the area would be facilitated by the reduction of congestion and through traffic on existing roadways. NEGATIVE IMPACTS: The proposed alternative would require the relocation of 70 (B) to 72 families (A) and 9 businesses. Approximately 60 (B) to 101 acres (A) of prime and unique farmland would be converted to highway rights-of-way. Ambient noise levels would increase at various locations along the corridor, and structure construction, erosion, and siltation would have both short- and long-term impacts on local streams.

AN - 36394284; 909 AB - PURPOSE: Levee and channel improvements with pumping facilities for localized drainage near the Saylor Street crossing on the Agana River in Guam are proposed. This supplement to the final environmental impact statement was prepared to address proposed changes in plans for flood control improvement at the Agana River, Guam. The preferred alternative would include a 1,700-foot floodwall and an 850-foot levee on the left side of the Agana River; 1,300 feet of concrete channel improvements between Agana Bay and upstream of Saylor Street; and 410 feet of riprap and unlined outlet channel to the ocean. The Marine Drive Bridge invert would be excavated to -4 feet mean sea level (msl), and the Saylor Street Bridge would be replaced. Interior damage requirements include an 850-foot-long storm drain on the left bank and various interior drainage culverts. The project would provide 100-year flood protection for Agana. The estimated first cost of the preferred alternative would be $4.9 million. Based on estimated annual benefits of $639,000 and estimated average annual costs of $454,000, including annual operation, maintenance, and replacement costs, the benefit-to-cost ratio would be 1.4. POSITIVE IMPACTS: The preferred alternative would encourage community growth and business activity in protected portions of the 100-year floodplain. The project would stabilize the basin and promote orderly future development. With flood protection, Agana Central Park would have the potential of becoming a major recreation-sports complex. Project control would decrease the potential for discharge of toxic materials from urban and commercial developments adjacent to the stream and marsh. NEGATIVE IMPACTS: Construction noise, dust, and air pollution may temporarily disturb residents and visitors to the Agana area. Approximately 0.4 acres of wetland habitat would be lost by construction of the floodwall. Approximately 0.5 acres of estuarine habitat would be displaced by the riprap lined channel, and the concrete flood control channel would displace 1,300 linear feet of riverine and estuarine habitat.

Preparation date: July 14, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - ICE-RELATED FLOOD CONTROL STUDY FOR THE DELAWARE RIVER, PORT JERVIS, NEW YORK AND THE BOROUGH OF MATAMORAS AND WESTFALL TOWNSHIP, PENNSYLVANIA. AN - 36386644; 917 AB - PURPOSE: A solution to the ice-related flooding problem in the area of the city of Port Jervis, New York and the borough of Matamoras and Westfall Township, Pennsylvania is proposed. The area is located on the upper mainstem of the Delaware River in the vicinity of the confluence of the Delaware and Neversink rivers near the New York, Pennsylvania, and New Jersey boundary. The selected plan consists of a clear-cut of trees within a 200-foot channel width following the alignment of the existing natural channel on the southeast side of the Mashipacong Island in Montague Township, Sussex County, New Jersey. Approximately 57 acres and some 2,300 trees would be cleared. Clearing would involve removal by chainsaw of all woody vegetation and surrounding brush. Cut lumber and debris would be taken offsite. An access road would be constructed for initial construction and subsequent maintenance of the project by upgrading an existing farm road paralleling the diversion channel on the north side of Mashipacong Island. Permanent land easements for 175 acres, of which 72 acres are owned by the National Park Service, would be acquired by the sponsors as part of the project. Maintenance would entail cutting of tree saplings by chainsaw and removal of any downed timber or debris from the channel. In order to facilitate access and minimize environmental impact, maintenance would be performed in late autumn after most plant dieback has occurred. Maintenance would be the responsibility of the local sponsor(s), but the project will be inspected annually by the Corps of Engineers. The selected plan maximizes net benefits and has a benefit-cost ratio of 1.31. The estimated first cost of construction is $1.0 million, with annual operation and maintenance costs of $13,000. POSITIVE IMPACTS: The performance of the project is such that stages for ice-related floods equal to or less than the magnitude of the 81-foot event would be essentially reduced to zero damage stage. In addition, a lesser degree of protection would be provided for ice-related floods of a higher magnitude. Average annual damage reduction would be $1.2 million. Short-term benefits would result from temporary employment during construction. NEGATIVE IMPACTS: Short-term detrimental impacts would result primarily from construction activities: the resulting dust, noise, and truck traffic will cause disruption proportionate to their relative distance and duration. Long-term detrimental impacts involve habitat modification, affecting wetland viability by reducing tree numbers. Although a certain degree of recovery could be expected, maintenance activities would generally prevent development into a mature forest for the life of the project.

AN - 36404258; 873 AB - PURPOSE: The project would involve demolition of virtually all existing buildings currently on site, except for the chill facility, and construction of new buildings. Facilities to be constructed would include berthing for 15 ships plus yard craft, waterfront support facilities, administrative buildings, unaccompanied enlisted personnel housing, recreational facilities, and a Shore Intermediate Maintenance Activity. The large L-shaped pier at the southern end of the existing facility would be reconstructed, and three smaller piers would be removed. A new pier and a 1,500-foot breakwater could also be constructed. The proposed carrier battle group (CVBG) deployment cycle would consist of a one-month predeployment sea trial, a six-month cruise period, and a 12-month assignment to the homeport. Personnel assignments at the Everett site would consist of approximately 8,300 military personnel, 7,800 dependents, 700 civilian personnel, and 906 civilian dependents. Approximately 50 percent of the military population would reside aboard their ships; an additional 465 would live onsite; and the remainder of the military and civilian personnel would reside in Everett, Snohomish, and King counties. In order to act on the Department of the Navy's environmental impact statement (EIS) to construct homeport facilities for a CVBG at the Norton Avenue Terminal in Everett, Washington, it was necessary for the Army Corps of Engineers to officially adopt the EIS. This is notification that the Corps of Engineers has adopted that EIS (see 86-0268D in this issue). POSITIVE IMPACTS: Development of a new homeport facility would be in keeping with the Navy's plan to expand to a 600-ship service and with the policy of decentralizing future naval forces. The Puget Sound area would provide an established naval support complex with protected deep waterways, plus existing industrial, commercial, and transportation networks. During the project construction period (1987 to 1990), a maximum of 1,000 jobs would be available. Actual operation of the homeport would generate approximately 16,000 direct and indirect jobs in the Everett/Snohomish county area. NEGATIVE IMPACTS: Approximately 2.5 million cubic yards of bottom materials would be removed from the site. The associated dredging activities could affect water quality, damage marine habitats, and result in temporary loss of sessile and motile organisms. Significant population growth in Snohomish County would require the construction of 8,600 new housing units and would place demands on county services. Since the major commissary and exchange, as well as some other facilities, would be located at the Sand Point Station near Seattle, population growth impacts would be distributed toward Seattle.

AN - 36405322; 905 AB - PURPOSE: Excavation of a navigation channel approximately 9,100 feet in length and the filling of an embayment with dredged materials in the Mallard-Fox Creek Area in North Alabama are proposed. The Morgan County Port Authority (MCPA) would develop a public port, including an overhead crane and mooring cells, within the study area. The primary goal in designing the project would be to allow a typical Tennessee River barge tow (15 barges) to traverse the port without having to be broken down. Current plans call for a gently curving channel 350 feet wide. Each end of the channel would intersect the navigation channel, with the midsection curving enough to be immediately adjacent to the existing bank. The proposed project was designed to provide direct port access to the Morgan County industrial site. It is estimated that excavation of the channel would produce 1 million cubic yards (mcy) of sandy clay fill material. The preferred disposal alternative proposed a 95-acre site, including 20 acres of embayment, lying directly adjacent to the proposed channel and within the boundaries of the Morgan County industrial site. This bay is completely exposed during the normal winter pool. During the summer pool, most of the bay is a shallow open water area surrounded by a narrow band of shrubs growing in less than two feet of water. With the construction of a short dike across its mouth, this embayment would be capable of holding approximately 1.2 mcy of fill material if filled to the elevation of adjoining properties. The estimated cost of the recommended plan is $5.2 million, with a benefit-cost ratio of 1.97. POSITIVE IMPACTS: Future navigation needs of the Morgan County area can best be met by building port facilities at the proposed Mallard-Fox Creek Industrial Park. Benefits of $599,500 were identified for base year traffic; chemical movements, which would begin in the year 2000, bring the average annual benefits to $707,000. The region surrounding the new port would benefit from increased economic development and the accessibility of low-cost water transportation. The industrial park adjacent to the port would provide employment opportunities and expand the industrial base. Given the scarcity of developable waterfront sites, large water-oriented industries would be drawn to the Mallard-Fox Creek Industrial Park. NEGATIVE IMPACTS: Filling of the embayment would result in the loss of eight acres of wetlands. Fish and wildlife resources would be diminished due to loss of habitat.

AN - 36404294; 874 AB - PURPOSE: This supplement was prepared because the Corps of Engineers determined that additional information was necessary before a decision could be made on the Department of the Navy's permit application to construct homeport facilities for a carrier battle group (CVBG) at the Norton Avenue Terminal in Everett, Washington. In order to supplement the Navy's final environmental impact statement (EIS), it was necessary that the Corps of Engineers officially adopt that EIS, which was accomplished (see 86-0267F in this issue). The purpose of this draft supplement is to provide information on the homeport project and on dredge disposal sites and methods. Approximately 3.3 million cubic yards of sediment would have to be removed. Contaminated surface sediments would be removed by a clamshell dredge; clean sediment would be removed with a hydraulic dredge. The preferred disposal site is a deep-water site for the contaminated sediments, which would be "capped" with the clean sediments. POSITIVE IMPACTS: Development of a new homeport facility would be in keeping with the Navy's plan to expand to a 600-ship service and with the policy of decentralizing future naval forces. The Puget Sound area would provide an established naval support complex with protected deep waterways, plus existing industrial, commercial, and transportation networks. During the project construction period (1987 to 1990), a maximum of 1,000 jobs would be available.

Preparation date: July 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - STACY RESERVOIR, DAM, AND PUMP STATION, CONCHO, COLEMAN, AND RUNNELS COUNTIES, TEXAS. AN - 36393396; 918 AB - PURPOSE: A permit application by the Colorado River Municipal Water District (CRMWD) is being considered for the proposed Stacy Dam, Reservoir, and Pump Station in the Upper Colorado River Basin of Texas. The project area is located within Coleman, Concho, and Runnels counties in Texas. The area to be inundated at elevation 1,551.5 feet above mean sea level (19,200 acres) consists of farm- and rangelands (including 5,000 acres of prime farmland) and encompasses the hamlet of Leaday, Texas. The reservoir is designed to allocate 103,000-acre-feet of water per annum for municipal and domestic purposes and 10,000-acre-feet of water per annum for industrial purposes, with an "adopted yield" of 90,700 acre-feet. Corps of Engineers alternatives are to issue a permit, issue the permit with conditions, or deny the permit. The Fish and Wildlife Service has recommended denial of the permit, based on an opinion that the project would jeopardize the continued existence of a proposed threatened species and the apparent availability of reasonable and prudent water supply alternatives. POSITIVE IMPACTS: Issuance of the required permits would allow the CRMWD to develop the available water resources at the Stacy Reservoir project site and thereby supply municipal and industrial water to customers in the water district's market area. The influx of construction personnel would have a mixed beneficial and adverse socioeconomic impact on the study area. NEGATIVE IMPACTS: Controversial issues include impact on a proposed threatened species, loss of current use of lands that would be inundated, terrestrial habitat losses, cultural resource losses, and disruption of community cohesion of project area residents. Cultural resources in the project area would require protection or salvaging. Some 34 people would be displaced from their homes. Approximately 5,000 acres of designated prime farmlands would be inundated. Stream segments with potential for designation as wild or scenic streams also would be inundated. Downstream riverine habitat would be variously impacted, depending on timing and volume of water releases from the dam. Based on available information, the project could jeopardize the continued existence of the Concho watersnake and adversely modify its proposed critical habitat.

Preparation date: July 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED DEVELOPMENT AND USE OF THE MALLARD-FOX CREEK AREA IN NORTH ALABAMA. AN - 36393340; 879 AB - PURPOSE: A land-use plan is presented for the 1,950-acre Mallard-Fox Creek Wildlife Management Area on the south shore of Wheeler Reservoir in Lawrence and Morgan counties, Alabama. In an attempt to balance conflicting needs for future land use, the Tennessee Valley Authority (TVA), under its preferred alternative, would commit 450 acres of land to industrial development by Amoco Chemicals Corporation and a number of smaller river-oriented industries, and would reserve the remaining 1,500 acres for long-term wildlife management. The change in development of the site, when Borg-Warner Chemicals withdrew its request for land in the area, from two large industries to a number of smaller river-oriented industries, dictated a change in river access from two terminals to a separate access channel the length of the area. In order to supplement the TVA's final environmental impact statement (EIS) with information relating to the construction of new port facilities at the proposed industrial park, the Department of the Army, Corps of Engineers has officially adopted that EIS. POSITIVE IMPACTS: Industrial development on a portion of the site would expand existing employment opportunities by creating 225 to 250 new jobs. Increases in secondary employment and retail service opportunities also would benefit the local economy. Commitment to wildlife management on the remainder of the site would preserve a wildlife habitat area and maintain an area for hunting and other recreational activities. NEGATIVE IMPACTS: The withdrawal of approximately 450 acres of land from an area now being managed for wildlife would have an adverse effect on the wildlife and present associated public use as the proposed industrial area is developed. Reduced numbers of several of the wildlife species would be able to continue inhabiting the area, but most mobile organisms would vacate the area. Most displaced organisms would be lost, and public use of the site would be displaced to other areas. Any water use-oriented industries within the proposed industry area would unavoidably disturb shoreline wetlands. Further, industrial development would preclude agricultural use. The commitment of the remaining 1,500 acres to wildlife management and other recreational uses would result in a reduction of the local area's ability to create new jobs or raise the standard of living for area residents and would forego realization of maximum agricultural production.

Preparation date: July 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - BALTIMORE HARBOR AND CHANNELS, MARYLAND AND VIRGINIA: 42-FOOT PROJECT (SUPPLEMENT TO GENERAL DESIGN MEMORANDUM NO. 1 OF MARCH 1961). AN - 36393368; 912 AB - PURPOSE: Dredging of the Brewerton Channel Eastern Extension (Connecting Channel to the Chesapeake and Delaware Canal) to its authorized depth is proposed. The purpose of this supplement to the March 1961 General Design Memorandum is to address the dredging of the uncompleted portion of the modifications authorized by the River and Harbor Act of July 3, 1958. All of the improvements authorized by the 1958 act have been constructed, with the exception of the Brewerton Channel Eastern Extension. The state desires that the Brewerton Channel Eastern Extension be dredged to its authorized depth of 35 feet so that vessels will no longer encounter a 1-1/4 hour delay by having to transit an additional distance of 12.2 nautical miles to and from Baltimore Harbor. The authorized dimensions of the Brewerton Channel Eastern Extension are 35 feet deep by 600 feet wide. The state of Maryland designated the Hart-Miller Island disposal area to contain the estimated 6.7 million cubic yards (mcy) of material requiring dredging to enlarge the channel to this depth and width. The estimated capacity of Hart-Miller Island is 53 mcy. Approximately 9.0 mcy have been deposited in Hart-Miller Island to date, with an additional 29.0 mcy of dredged material presently scheduled to be deposited in the facility. Adequate capacity, therefore, exists to contain the 6.7 mcy of material to be dredged from the Connecting Channel. The maintenance plan for the Connecting Channel consists of performing annual hydrographic surveys and periodic maintenance dredging approximately every five years. The annual costs of operation and maintenance are estimated at $1.1 million. POSITIVE IMPACTS: Project benefits were based on transportation savings resulting from reduced operating, pilotage, and labor cost savings to vessels with drafts in excess of 27 feet that would be able to use the Brewerton Channel Eastern Extension as a result of the project deepening. Additionally, vessels currently operating in an unsafe manner, with an underkeel clearance of less than three feet, would be able to operate safely. The proposed plan meets federal requirements for maximizing national economic development. NEGATIVE IMPACTS: Increased channel depths would alter salinity levels in the Chesapeake Bay and the James, York, and Patapsco rivers. Dredging and disposal operations would destroy benthic organisms and result in temporary turbidity in the immediate areas of such operations. Sediments dredged from Maryland waters would contain toxic materials, and disturbance of these sediments would release the materials into the water column.

Preparation date: July 3, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED WOLF CREEK VALLEY SKI AREA, SAN JUAN NATIONAL FOREST, MINERAL COUNTY, COLORADO (REVISED DRAFT ENVIRONMENTAL IMPACT STATEMENT). AN - 36399485; 884 AB - PURPOSE: Development of a downhill ski area, located approximately 12 miles north of Pagosa Springs, Colorado on U.S. Highway 160 in the area commonly known as Windy Pass in the Pagosa District, San Juan National Forest in Mineral County, Colorado, has been proposed by Westfork Investment, Ltd. This revised draft environmental impact statement discloses projected environmental consequences of developing the new ski area. Under the preferred alternative, development would be phased, with the first phase having a capacity of 4,050 skiers at one time, four lifts, and 253 acres of trails. Future phases would be completed as the market may justify. At project completion, the ski area would have a capacity of 11,750 skiers at one time, 14 chairlifts, a gondola, and 904 acres of trails. Approximately 2,700 acres of National Forest System land would be under permit. An area included in the proposal and of particular importance to the proponent is that referred to as the back bowls. Four lift systems are proposed to service this terrain, which is in an open bowl configuration with natural parks and openings and glades of aspen intermixed with spruce fir. Ability levels serviced by the proposed lifts range from low intermediate to expert. The four back bowl lifts would operate at a relatively low hourly capacity in order to maintain a low-trail density of five skiers per acre. A capacity of 1,750 skiers at one time is proposed in an effort to assure a quality skiing experience. The ski base area would be located on private land immediately adjacent to the base lift terminals and ski runs. The ski base would contain skiing oriented services, a base lodge, transit facilities, and skier parking in a combination of surface parking lots and parking structures. To accommodate this base, approximately one mile of U.S. Highway 160 would be relocated 550 feet west of the current alignment. The proposed relocation would be designed to meet the requirements of a Type B roadway with a design speed of 65 mph, with two 12-foot lanes and 8-foot paved shoulders on each side. Where auxiliary climbing lanes are necessary, they would be 12 feet wide and the shoulder would be reduced to 4 feet. The estimated cost of the proposed road realignment would be $2.8 million and would be borne wholly by the proponent. A full range of housing units and services would be developed in the ski base area and ultimately would include 20 single-family residences, 78 townhouses, 476 condominiums, and 220 condominium-hotel units. In addition, approximately 65,000 square feet of ski-related commercial retail space would be built at the ski base. Two 18-hole golf courses, an equestrian center, a trail system, and water-oriented recreation uses would be included in the program. POSITIVE IMPACTS: Within the total area proposed for development, significant cultural resources would be preserved. Because of the high value of the vegetation to the development, the danger of wildfire spreading onsite would be reduced. In some cases, there would be an opportunity for improving certain wildlife habitats. Development will enhance and help diversify the economic base of the area and would increase employment opportunities. The development would help meet projected demand trends for downhill skiing and increased use of the San Juan National Forest. Water quantities are anticipated to increase due to tree cutting for ski trails and the nature of snowfall as affected by wind circulation, which will result in earlier snowmelt runoff. NEGATIVE IMPACTS: Development of the ski area would be phased, and the first steep trails cleared would have a relatively high risk of natural and construction-induced slope failures, with increased debris flows from landslides and ski trail construction. There would be less visual diversity and character, especially in the fall, because of the removal of some aspen trees. An estimated 28 percent of the total timber/vegetation types on public land would be impacted. Vegetation disturbance would affect wildlife habitat over the entire proposed permit area. The realignment of U.S. Highway 160 would have a short-term impact due to land disturbance resulting from construction. A proposed lift could affect one archaeological site on National Forest System land. Noise levels will increase as a result of increased traffic and operation of the ski area (lifts, slope maintenance vehicles, snowmaking, etc.).

Samples of oysters, clams, and surface sediments were collected. Tissue sample were processed either by the procedure of Rogerson and Galloway or by the procedure of Martin and Knauer and EPA. The former were analyzed by graphite furnace atomic absorption spectrophotometry (GFAAS) and the latter by gas hydride atomic absorption sepctrophotometry (GHAAS). Sediment samples were processed by the method of Eisler and subsequently analyzed by FAAS/GFAAS. For the determination of arsenic, mercury, and selenium, the sediment samples were processed as follows. A 50% solution of nitric acid was added to the sample and 5 ml of 5% potassium permanganate was further added. The solution was heated and hydrogen peroxide was added. The solution was filtered and sodium chloride-hyroxylamine hydrochloride solution was added. This sample was analyzed by GHAAS. The final sample solutions were analyzed by flame or flameless graphite furnace AAS on an atomic absorption spectorphotometer. Of the 12 metals tested, only thallium was not observed in tissue samples. Oysters collected at the IHNC contained extremely high concentrations of zinc, whereas the clams from the other two passes contained higher concentrations of copper. Oysters from IHNC possesed higher concentations of lead, cadmium, and mercury than the clams. Comparison of the levels of heavy metals in the biota and surface sediment of other Gulf Coast estuaries revealed similar concentrations.

AN - 36393300; 859 AB - PURPOSE: Construction of a diked disposal facility within the Crow Island State Game Area is proposed for backlog and maintenance materials dredged from the Saginaw River navigation project, Saginaw and Bay counties, Michigan. Changes in the preferred alternative are outlined in this draft supplement to the environmental impact statement. The revised plan proposes construction of a confined facility on the 66-acre island within the Northwest Unit of the Crow Island State Game Area. On the island, an irregularly shaped area encompassing approximately 52 acres would be built. The confinement area would consist of a combination dike and excavated area. Beginning inside the perimeter, at a distance of approximately 150 feet, a pit would be excavated. An eight-foot wide clay seal would be placed from grade to the underlying clay, thus sealing the area to prevent any loss of contaminants into the environment. The excavated clay material not used in the perimeter dike would be disposed of in the most economical way that would provide a beneficial use. Three fill areas would be placed on the soft bottomland area west of the dike/pit area. This would be 330 feet wide and 1,200 to 1,400 feet long. Along these fill areas, a number of small Common Tern nesting areas would be constructed. At the northeast corner of the dike/pit area, a 150-foot wide dike approximately 1,000 feet long would be built. At the point where the dike crosses the open water and ties to the existing dike, two 4-foot square box culverts with slide gates would be added to provide water control for the 47-acre body of water between the island and existing dikes. In order to provide complete water control for the 47-acre area, a pumping facility would be provided. The remaining project features for mitigation include a 35- to 100-foot-wide channel cut to elevation 0.0 along the north side of the dike/pit and water control dike. The site would be graded to provide an 11-acre pond at the north end of the site and a 9-acre pond at the sound end. Between the ponds, a hill would be formed. Three thousand trees and shrubs would be planted along the east side of the original pit area for wildlife food, habitat, and cover. Construction cost for the revised plan is $13.3 million. POSITIVE IMPACTS: The project would convert a relatively unproductive, mostly open-water area to a diked area with diverse habitat types, which will be managed for wildlife and fish use. Dredging would ensure continued navigational use of the Saginaw River. NEGATIVE IMPACTS: Open-water habitat acreage would decrease by approximately 59 acres as a result of island construction and by 9 acres as a result of perimeter diking.

AN - 36387183; 868 AB - PURPOSE: Implementation of a plan for navigation improvements to the Claremont Terminal Channel, Jersey City, New Jersey is proposed. The selected plan calls for dredging a 34-foot deep, 300-foot wide centrally aligned channel that narrows and adjoins the land at its western end and flares at its eastern end to join the main navigation channel through New York Harbor. The material to be removed (1.7 million cubic yards) would be disposed at a shallow ocean disposal site currently utilized for such material (mud dump). Costs to strengthen an old retaining dike along the northwestern edge of the waterway have been included in the project costs. Silt screens should be used in front of the mudflat not protected by the dike to minimize sedimentation. Dredging in this area would be avoided during the summer to avoid creation of an anoxic environment. In order to implement the requirements of Section 404 of the Federal Water Pollution Control Act, an exemption is being sought. POSITIVE IMPACTS: The plan is environmentally acceptable in that the deeper channel would increase tidal flushing and improve long-term water quality in the channel, as well as reduce vessel emissions and chances for spills and accidents. NEGATIVE IMPACTS: Dredging impacts would be minimal and short-term and confined to previously disturbed areas; shoal habitat would essentially remain the same except for the loss of a small, 1.5 acre, isolated shoal in the backwater portion of the channel.

AN - 36400327; 866 AB - PURPOSE: Information on proposed fish and wildlife mitigation measures to offset project-induced losses and results of water quality studies are presented in a supplement to the final environmental impact statement of October 1977 on the Twin Valley Lake-Wild Rice River Flood Control Project in Norman County, Minnesota. The project would involve construction of an earthfill dam, 1,200 feet long and 85 feet high, across the Wild Rice River at a point approximately 1.5 miles upstream from Twin Valley, to create a 52,200-acre-foot impoundment for recreation and flood control uses. This supplement to the final environmental impact statement provides additional information on proposed fish and wildlife compensation measures to offset project-induced losses, the results of water quality studies conducted by the Army Corps of Engineers, and a Section 404(b)(1) evaluation. The recommended fish and wildlife compensation plan consists of mitigation measures that would provide a level of compensation as close as possible to full compensation in the least costly manner by minimizing land acquisition and maximizing management. The plan includes management of the reservoir fishery; management of project lands that would offset terrestrial losses by approximately 30 percent; and acquisition and management of approximately 1,600 acres adjacent to the existing Faith Wildlife Management Area. This feature would offset terrestrial losses by approximately 70 percent. The proposed compensation plan would have an estimated cost of $1.4 million. POSITIVE IMPACTS: The reservoir would provide flood control for downstream areas, control siltation in downstream flows, and provide recreational opportunities for area residents. Wildlife and fish mitigation measures would preserve acquired habitat areas from encroachment by exploitative land users. NEGATIVE IMPACTS: The impoundment would inundate 540 acres of riparian habitat permanently, and the flood pool would convert an additional 1,100 acres of riparian and upland habitat to an open grassland, due to periodic inundation. Water quality studies indicate that water quality impacts of reservoir construction and operation would be minimal and limited to the addition of a yellowish color and soluble organic forms of carbon, nitrogen, and phosphorus to the water. More severe water quality impacts would result if the reservoir stratified for more than 8 to 10 days.

AN - 36401121; 869 AB - PURPOSE: Construction of Candy Lake and a dam on Candy Creek, located approximately 1.9 miles above its confluence with Bird Creek, in Osage County, Oklahoma, is proposed. Candy Lake is a multipurpose project for flood control, water supply, recreation, and fish and wildlife. Construction of the lake began in September 1976 and is approximately 15 percent complete. In 1981, construction was halted and was indefinitely delayed by a Department of Justice decision to withdraw condemnation proceedings to acquire mineral rights from the Osage Indian Nation. Interim management of the federal lands without the authorized project in place is proposed in this supplemental information report. Under the preferred alternative, the Army Corps of Engineers would prepare a General Plan Document for Candy Lake and then issue a license to the Oklahoma Department of Wildlife Conservation (ODWC) permitting that agency to manage the 3,658 acres of land for wildlife. The license would be terminated in the event that the project is deauthorized or construction is resumed. The ODWC has indicated that if it was issued a license, it would be willing to invest in permanent capital improvements at the project. Boundary marking and fencing are proposed in ODWC's management plan as part of its license request. Under the preferred alternative, ODWC would provide improved public access for wildlife-oriented recreation; would fence and sign the boundary, which would aid the public in identification of public land; would construct parking lots; would close existing unneeded trails to prevent off-road use; and would control unsightly overgrazing activities. POSITIVE IMPACTS: Intensive management would help discourage illegal uses of Candy Lake lands. Boundary marking and fencing would assist in controlling possible public trespassing on private lands adjoining the project and would discourage trespass grazing and timber cutting. With controlled grazing, vegetation quality and diversity would be improved. There would be some minor improvement in water quality in Candy Creek. The preferred alternative would result in improved habitat conditions and subsequent increased wildlife populations.

AN - 36402176; 833 AB - PURPOSE: Relocation of two Auxiliary Oil and Explosive Ships (AOEs) from Naval Station Norfolk, Virginia to Naval Weapons Station (NWS) Earle, Monmouth County, New Jersey is proposed. This report supplements the final environmental impact statement issued in 1980 by the Navy and adopted in 1986 by the Army Corps of Engineers. In general, the scope of the project has been downgraded as a result of the reduction in pier and trestle size and dredging requirements. Under the preferred alternative, a new pier (No. 4) would be constructed adjacent and parallel to Pier 3. The pier would be 900 feet long and would be connected to the existing pier structure by a 1,500-foot-long trestle. The pier would be constructed of 42-inch steel pipe piles with concrete slab decking. The existing navigation channels and turning basin in the vicinity of the pier would be dredged to an operating depth of -45 feet mean low water (mlw) with 2-foot overdraft, resulting in 8.2 million cubic yards (mcy) of dredged material. The sand/silt/clay material would be deposited at the Ocean Disposal Dump site (the Mud Dump) approximately six miles offshore of Sandy Hook. A ship fuel replenishment system consisting of fuel storage facilities and an oil-water separation system would be constructed. Six smokeless powder and projectile magazines would be located at the Main Station Area to be used for the storage of ammunition. POSITIVE IMPACTS: The proposed action would provide an efficient homeport facility with a high degree of military readiness. Explosive and navigation safety would improve, reducing the risk of accidents and oil spills. In the long term, an increase in recreational benefits is expected. Habitat for beach nesters, including the piping plover and least tern, would be increased. The increase in hard substrate resulting from the new pilings would have long-term beneficial impacts for sessile organisms and for fish as a result of increased intra-pier habitat. Compton's Creek navigation channel would not be encumbered by the Explosive Safety Quality Distance arc. NEGATIVE IMPACTS: Pier construction would result in the destruction of the benthic habitat and organisms located at each piling site. Short-term impacts include the degradation of local air quality and an increase in noise levels during construction. An increased navigation restricted area around the pier would have a minor impact on water-related recreational uses. The increased navigation restricted area would reduce the general anchorage area of Sandy Hook Bay by 1.5 percent.

AN - 36393242; 871 AB - PURPOSE: Construction of a multipurpose dam on Palo Duro Creek in Hansford County, Texas is proposed to provide water supply and recreational opportunities, reduce looting, and preserve natural and cultural resources in the area. The rolled earth dam, which would be located 34.7 miles above the creek's confluence with the North Canadian River, would extend 4,900 feet across the creek and rise 170 feet above the creek's bed. A 200-foot-wide, limited-service spillway and a 6.5-foot-diameter gated conduit would be situated in the right abutment. The dam would create a lake with a surface area of 2,122 acres at the top of the conservation pool and 7,574 acres at the top of the flood control pool. Total capacity of the impoundment at full flood pool would be 350,540 acre-feet, including 40,000 acre-feet within the conservation pool. The impoundment would have a maximum dependable yield of approximately 7.8 million gallons per day; water-treatment and conveyance facilities would be constructed in association with the impoundment. Ancillary facilities would include fish and wildlife and recreation resource management measures; road, railroad, and bridge construction; pumping stations and pipelines; and project buildings and utilities. Cost of the project is estimated at $138 million, and the benefit-cost ratio is estimated at 1.2. POSITIVE IMPACTS: Water from the impoundment would provide for the needs of users in the towns of Dumas, Gruver, Perryton, Spearman, Stinnett, and Sunray. Flood control from storage of flood flows behind the dam would prevent an average annual loss of $102,500 in property damage. The impoundment and associated facilities would also provide for expansion of recreational, wildlife, and fishery resources associated with Palo Duro Creek. NEGATIVE IMPACTS: Creation of the conservation pool would inundate 2,101 acres of land permanently, and use of the flood control pool would inundate an additional 5,430 acres periodically. Vegetation around the perimeter of the permanent pool would undergo transition to species characteristic of mesic conditions, and a corresponding shift in wildlife populations would occur. Losses due to creation of the conservation pool would include 1,387 acres of floodplain prairie, 362 acres of riparian land, and 165 acres of canyon breaks. Approximately 21 acres of stream and pond habitat would be inundated permanently, and an additional 22 acres of such habitat would be inundated periodically. Approximately 46 archaeological and 9 historic sites would be subject to periodic or permanent inundation. Approximately 224 acres and 1,253 acres of prime farmland would be inundated by the conservation pool and flood control pool, respectively.

AN - 36397596; 864 AB - PURPOSE: A flood control study project is proposed for the Lake Susupe-Chalan Kanoa area of Saipan, Commonwealth of the Northern Mariana Islands. The principal features of the recommended plan consist of a 3,833-foot levee, a 1,300-foot road raise, a 500-foot road lowering, a 2,200-foot concrete-lined outlet channel, one interior drainage culvert, and four culverts under As Lito Road. The drainage channel enters Saipan Lagoon near Hopwood Jr. High School. The plan would involve creating open-water habitat sites for endangered water birds and migratory waterfowl. The proposed habitat would involve dredged open-water areas adjacent to the eastern edge of the levee and between As Perdido Road and the proposed outlet channel. Approximately four acres of open-water ponds would comprise the habitat. Associated measures, including the introduction of suitable food plants and loafing sites, would be implemented. The non-federal share of the project total first costs is approximately $1.2 million. POSITIVE IMPACTS: The proposed measures would reduce flood hazards to existing development areas or protect 140 to 300 acres of land against flooding. The completed project would protect or reduce flooding for up to 656 homes, 44 commercial structures, and 52 public facilities in the study area, amounting to a reduction of an estimated $114,000 in direct flood damages annually. Public utilities would be protected, and development potential would be enhanced. NEGATIVE IMPACTS: The project would displace agricultural operations on 2.5 acres; disturb forest bird habitat, marsh soils, and wetland vegetation; and destroy fish life and water bird habitat, including habitat of the endangered Marianas mallard, Nightingale Reed warbler, and gallinule. Some nearshore sand flats would be disturbed, and potential archaeological artifacts could be destroyed.

Preparation date: June 9, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CONSTRUCTION OF A DREDGED MATERIAL CONFINED DISPOSAL FACILITY AT TOLEDO HARBOR, OHIO. AN - 36398326; 825 AB - PURPOSE: Construction of a confined disposal facility (CDF) for polluted sediments dredged from the Maumee River federal navigation channel at Toledo, Ohio is proposed. Toledo Harbor is dredged annually, using normal operation and maintenance authorities of the Corps of Engineers. Objectives of the plan include maintaining adequate water depths for commercial and recreational navigation; providing safe handling and transportation of heavily polluted sediments to a permanent, confined disposal site (or sites); minimizing adverse impacts to aesthetics and fish and wildlife values; protecting water quality; and preserving significant cultural resources. A new dike wall, approximately 4,265 feet in length and 29.5 feet in height, would have to be constructed to enclose 162 acres of water adjacent to the federal channel and the existing federal CDF. In addition, the dikes of the existing federal CDF and the Toledo Edison Disposal Area would be reconstructed and elevated to a height of 29.5 feet for a distance of 3,412 feet. This would provide sufficient capacity (8.8 cubic yards) for 21.9 years of consolidated dredged material from Toledo Harbor. The first cost of the plan is $11.7 million, with net benefits of $4.9 million, for a benefit/cost ratio of 2.05. POSITIVE IMPACTS: The full commercial and recreational navigation potential of Toledo Harbor would be assured for 25 to 28 years. Businesses and industries that rely on Toledo Harbor navigation would continue and /or expand, and the project would facilitate area growth. Minor increases in employment would be seen during CDF construction, and harbor-related employment would be maintained. The proposed plan would allow for continual dredging of polluted sediments and confined disposal for the next 25 to 28 years. Construction of the dike would tend to deflect more polluted Toledo River water further into Maumee Bay, increasing dilutional effects. NEGATIVE IMPACTS: The proposed alternative would result in the loss of approximately 162 acres of muddy bottom habitat and sandy shoal habitat, as well as some riprapped shoreland and aquatic emergent vegetation.

Preparation date: June 4, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - GREAT I IMPLEMENTATION, 9-FOOT CHANNEL PROJECT, UPPER MISSISSIPPI RIVER: FINAL SUPPLEMENT FOR LOWER POOL 5 CHANNEL MAINTENANCE/WEAVER BOTTOMS REHABILITATION PLAN, MINNESOTA AND IOWA. AN - 36393684; 823 AB - PURPOSE: Operation and maintenance of 13 locks and dams in a 9-foot channel, 242.5 miles long, in the Mississippi River from Minneapolis, Minnesota to Guttenberg, Iowa are proposed. The project consists of necessary channel dredging to maintain a 9-foot depth for navigation on the Mississippi River and 14.7 miles on the Minnesota River, 24.5 miles on the St. Croix River, and 1.4 miles on the Black River in Iowa, Minnesota, and Wisconsin. This supplement describes the general channel maintenance plan for lower pool 5 on the Upper Mississippi River, including rehabilitation of the 4,000 acre backwater lake, Weaver Bottoms. The primary objectives of the project are to develop a 40-year channel maintenance plan for lower pool 5, to reduce maintenance dredging requirements in lower pool 5, and to restore the habitat quality of the Weaver Bottoms area by modifying side channels and constructing islands with maintenance-dredged material. POSITIVE IMPACTS: Modifying the side channels would increase the efficiency of the channel, thereby enhancing recreation, commercial navigation, and hunting. The local economy would also be enhanced by the employment of local workers and the use of the local quarries. The preferred alternative would substantially reduce the existing sedimentation problems in Half Moon Lake and near the side channel openings into Weaver Bottoms. It would preserve the area for fish and wildlife. The project would reduce dredging volumes by 260,000 cubic yards of sediments every 40 years (6,500 cubic yards annually). Overall, the project is expected to have a very positive environmental benefit on the Weaver Bottoms backwater by improving abundance and diversity of aquatic vegetation; improving furbearer and waterfowl feeding, resting, and nesting habitats; and increasing recreational opportunities. NEGATIVE IMPACTS: The reduced number and modification of the remaining access points may somewhat impede fish movement into and out of the Weaver Bottoms area. Approximately 100 to 108 acres of aquatic habitat would be directly modified, of which approximately 13 to 18 acres of side channel habitat would be modified to partial rock closing structures that could become valuable areas for fish and other aquatic organisms. The remaining side channel areas would be modified to terrestrial habitat. Project construction would have short-term negative effects on land transportation, noise, and area aesthetics.

Preparation date: June 4, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - FLOOD PROTECTION IN THE ECORSE CREEK DRAINAGE BASIN, WAYNE COUNTY, MICHIGAN. AN - 36380163; 865 AB - PURPOSE: A flood protection project is proposed for the Ecorse Creek Drainage Basin, Wayne County, Michigan. The project would include the construction of four retention basins that would function as temporary detention sites for floodwaters in excess of the bank-full capacities. Two in-stream box culverts would be built to provide functional support for the retention basin inlet pipes. A total of approximately 130 acres of existing grassland, shrub /scrub, and tree-covered land would be used for retention basin sites. The retention basins would be protected from recreational and urban development for the life of the project (100 years). They would be seeded with selected grasses, and perimeter levees would be planted with fruit-bearing shrubs and tree species selected to maximize wildlife habitat for small mammals and song birds. Sanitary system backup and associated sewage contamination related to surface water flood events would be eliminated. The estimated first costs are $18.5 million; annual costs are $1.9 million. POSITIVE IMPACTS: The implemented flood protection project would meet the major needs of the public and private sectors of the basin. Flood damage would be reduced while maintaining aesthetic features. The creation of additional wetland areas and the protection of approximately 130 acres of land as wildlife habitat for the 100-year life of the project are benefits that would result from the project. Habitat preservation and sewage contamination abatement are positive long-term environmental impacts. NEGATIVE IMPACTS: Negative environmental impacts would be primarily temporary in nature. These would include (1) temporary displacement of resident small mammals, rodents, song birds, and some ring-necked pheasants; (2) temporary increases in near stream, stream bank, and in-stream erosion rates for approximately a two-year post-construction period; (3) temporary degradation of water quality during the two-year post-construction period; and (4) temporary adverse impacts in noise and aesthetic quality during construction operations.

AN - 36399421; 882 AB - PURPOSE: Implementation of a plan by which the Pacific Coast Molybdenum Company, a subsidiary of U.S. Borax, would consolidate three operations on one site located in the city of Hoquiam, Washington is proposed. The three components are: (1) constructing and operating a molybdenum refinery; (2) dredging a barge slip, constructing a wharf, and developing a marshalling yard for shipping supplies to the Quartz Hill mine near Ketchikan, Alaska; and (3) constructing facilities for prefabricating modular facilities and preassemblies that would be shipped to Quartz Hill. The proposed site, owned by the Port of Grays Harbor, is on the north shore of Grays Harbor immediately west of the mouth of the Hoquiam River. The plan is to concentrate the ore at the mine in southeastern Alaska, place bagged concentrate in sea containers, and barge the material to the Grays Harbor facility for refinement into molybdenum trioxide. A portion of the molybdenum trioxide would be further processed to other molybdenum-based chemicals. Finished products would be transported by truck, rail, and ship. The other part of the proposal is to use a portion of the refinery site for the construction of prefabricated "modules" that would be barged to Alaska for use in mine development. The site would also be used during mine operations to collect and ship operational supplies such as reagents and grinding balls. The refinery and transhipment facility would cover approximately 26 acres and have a pier extending into Grays Harbor for barge loading and offloading. The remaining 17 acres would be used for the support of Quartz Hill construction and would include a barge basin excavated into the fill at a right angle from the harbor. POSITIVE IMPACTS: the proposal could create substantial economic benefits to Grays Harbor County through additional jobs and tax revenues. The annual cost for the supplies and material needed to operate the proposed facility is estimated to be approximately $7.75 million, a portion of which would be spent in the county. Estimated annual property tax revenues of $1.3 million would accrue to the county and the city of Hoquiam. The applicant expects to export 60 percent of the processed molybdenite to Asia and Europe, which would benefit the balance of trade accounts of the United States. NEGATIVE IMPACTS: The western half of the site would either be paved with an impermeable material or covered with the concrete foundations of the process buildings. Site preparation, barge basin excavation, and installation of the wharf, effluent outfall, and storm drains would increase the potential of erosion from the site. Hoquiam River outflow would be affected by the proposed transhipment wharf. Construction could cause runoff that would be high in suspended solids. Accidental spills could happen during all phases of the project. The direct impacts on the aquatic environment would consist of: (1) physical destruction of intertidal and subtidal habitat; (2) alteration of water quality and possible adverse effects on biological communities; and (3) increased turbidity. Increased traffic could cause considerable congestion. Since workers would most likely be brought in from other areas, there would be an adverse effect on the existing housing supply. Barge traffic associated with the proposal would interfere with the fishing areas of the Quinalt Indian Tribes. Construction of the refinery would eliminate a 27-acre wetland.

Preparation date: June 1, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - KANAWHA RIVER NAVIGATION STUDY: WINFIELD LOCK REPLACEMENT, INTERIM FEASIBILITY REPORT, PUTNAM COUNTY, WEST VIRGINIA. AN - 36385425; 872 AB - PURPOSE: Construction of a lock replacement at Winfield Locks and Dam, Kanawha River near Eleanor, Putnam County, West Virginia is proposed. The Winfield Locks and Dam Facility is located at Kanawha River Mile 31.1, approximately 27 miles downstream of Charleston. The preferred alternative would add an additional lock at the existing project site, continue to use the riverward lock, and deactivate the present landward lock. The lock would be 800 feet by 110 feet. Channel widening downstream from the existing Winfield project also is recommended as part of the improvement plan. Mitigation measures include on-site, in-kind replacement of a stream, 21 acres of wetland habitat, and 60 acres of high quality farmland. The plan would require acquisition of approximately 36 acres of land for construction of the lock and approaches and another 145 acres for the disposal of excavated material. Facilities to safely accommodate the public are also included in the plan. The estimated construction cost of the preferred alternative would be $152 million. Annual economic costs for a 50-year project life are $17.5 million. The annual economic benefits would be $70 million, yielding a benefit to cost ratio of 4:1. POSITIVE IMPACTS: The key effect of the new lock would be the virtual elimination of waiting tows outside the project approach areas. This beneficial impact would effectively end the recurring disturbance of nearshore habitat by moored tows waiting for passage through the facility. Safety would be improved due to efficient movement of traffic and minimization of congestion. The site would be managed as a wildlife area by the West Virginia Department of Natural Resources. NEGATIVE IMPACTS: Losses of 0.6 mile of stream, wildlife habitat, wetlands, a small pond, and prime farmland due to disposal of excavated material would be mitigated. Construction of the lock would foreclose the urbanization of approximately 180 acres. Four recorded archaeological sites would be impacted. Twenty-eight families occupying 28 mobile or modular homes would be displaced. The lock would result in some minor adverse impacts to small streams and the Kanawha River.

AN - 36402500; 821 AB - PURPOSE: Construction of hurricane protection measures along Bayou Lafourche from Larose to Golden Meadow, Louisiana is proposed. The project would consist of a 36-mile loop levee along both banks of Bayou Lafourche. First lifts on most levee sections on the western side of the bayou have been completed. This supplemental information report complements the final environmental impact statement of October 1973 and addresses the refurbishing of an existing access channel and shell "lock." This work is necessary to provide borrow area access for the second lift of the Section A-West levee. Access to the borrow area would be gained by using an existing previously used canal adjacent to the levee, removing and replacing two shell closures, and upgrading protection dikes between the closures. Recently accumulated bottom sediments from the 75-foot wide by 2,000-foot long flotation channel would be bucket dredged with a barge-mounted dragline to a depth not to exceed -10 feet. The material removed would be placed in adjacent 100-foot wide disposal areas. One temporary and one permanent shell closure, located approximately 200 feet apart, would be degraded and replaced to allow the barge and equipment to "lock-through." Two interim protection dikes between the shell closures would be upgraded if necessary. POSITIVE IMPACTS: Equipment would have access to a borrow area on the protected side of the hurricane protection levee. NEGATIVE IMPACTS: Dredging the access channel would impact approximately 5 acres of man-made canal, and placement of material removed would affect some 10 acres of previously used disposal areas. Upgrading the interim protection dike would impact approximately one-half acre. The impact on the environment would be negligible; on termination of work, the area would return to preexisting conditions.

AN - 36399717; 824 AB - PURPOSE: Implementation of a flood protection plan for Newark, in Licking County, Ohio from the North Fork of the Licking River is proposed. The selected plan calls for a 90-foot channel from the mouth of the North Fork to Manning Street and correction of an existing slip in the project area. The length of the project is 8,400 feet. The channel work would consist of widening the stream to a consistent 90-foot width. Sandbars would be removed in several locations. The existing low-flow channel would be maintained in 6,793 linear feet or 77 percent of the project. A trapezoidal channel would be constructed in two reaches for a total of 2,050 linear feet. Most of the widening would occur on the east bank. The new banks would be stabilized with 2-foot thick stone riprap with a slope of 1 to 2.5. Rock structures would be placed on the stream bottom in seven areas as mitigation for possible damages to aquatic life. Slush-grouted concrete paths and level streamside platforms would be built into the riprapped channel bank to maintain existing public access to the stream. A paved road would extend along the top of the left descending bank between Manning Street and Everett Avenue to provide access for project operation and maintenance. Annual benefits are estimated at $1.8 million, with annual costs of $690,000. The total estimated cost would be $6.8 million with a benefit/cost ratio of 2.6. POSITIVE IMPACTS: The plan would reduce flooding to the 80-year frequency. The riprap on the banks would prevent bank erosion and possible damage to land on the upper banks. The reduced frequency of flooding would also reduce private expenses for residential and industrial repairs, flood insurance premiums, and expenses for the Federal Insurance program. Property values in the floodplain would increase. Social well-being in Newark would be enhanced by safety and financial security of residents and business establishments. NEGATIVE IMPACTS: Approximately 18 acres of bank area would be disturbed for channel modification and nearly all habitat of trees, shrubs, and grasses would be removed. Both aquatic habitats and stream biota would be adversely affected. The natural diversity of plant and animal life and stream character would be changed adversely by the uniformity of the riprapped stream banks and lack of vegetative cover. Additionally, an area of approximately six acres would be disturbed in the correction of a landslide located between Buena Vista Drive and the North Fork. Approximately 10 acres of open ground northeast of Buena Vista Drive would be used as an upland disposal area.

Preparation date: May 29, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MAINTENANCE OF BLACK WARRIOR AND TOMBIGBEE RIVERS, ALABAMA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF APRIL 1976). AN - 36398675; 817 AB - PURPOSE: Implementation of a maintenance plan for the Black Warrior and Tombigbee (BWT) rivers, Alabama is proposed. The BWT Waterway provides for a channel 9 feet deep and 200 feet wide, extending from the mouth of the Tombigbee River 45 miles above Mobile to the vicinity of Birmingham, a total waterway distance of approximately 463 miles. This supplement to the final environmental impact statement describes the planned operation and maintenance of this system through the year 2005. The proposed plan includes (1) constructing training dikes at two sites below Coffeeville Lock and Dam; (2) expanding the dredging reaches from the 53 miles presently approved to a total of 87 miles; (3) performing up to eight feet of advanced maintenance dredging at identified heavy shoaling locations; (4) increasing the within-banks disposal areas from the 69 miles presently approved to a total of 122 miles; (5) providing additional diked upland disposal areas of approximately 1,090 acres in addition to the 1,161 acres presently being utilized; (6) increasing the number of small-boat access channels that could be maintained; and (7) alleviating the navigational hazard at the Southern Railroad Bridge at Jackson, Alabama and reducing annual dredging quantities by maintaining the flow through this section. POSITIVE IMPACTS: The general operation and maintenance plan would provide for the continued use of the project and would enhance recreation, fish, and wildlife resources wherever possible. It is projected that dike fields on the BWT would produce habitat enhancement for both macroinvertebrates and fish. The 3,000-foot longitudinal dike on the left-descending bank would provide increased surface area for organism attachment and increased fish food organisms. The dikes would have the additional benefit of maintaining boat access to the severed bendway. NEGATIVE IMPACTS: The seven training dikes and the area in between each dike will cover an area of 14.9 acres of existing river bottom, thus destroying the benthic communities presently colonizing this area. The most significant impacts of diked upland disposal practices would be the loss of bottomland hardwood habitat. An estimated 482 acres of productive pasture- or cropland would be lost and, unless the sand is removed, would remain nonproductive for agricultural uses. The construction of the training dikes would result in temporary increases in noise and air pollution levels, turbidity, and a temporary reduction in the photosynthetic rate. Benthic communities would be destroyed in the areas dredged for small boat channel maintenance and on aquatic disposal sites, and fish habitat would be disrupted on a short-term basis. Since all proposed upland disposal areas are within the floodplain of the river, there is a potential for erosion of the dikes surrounding the area; during flood conditions, the water flowing out of the river banks could cause dike erosion resulting in the deposition of material within the disposal area onto terrestrial habitat or back into the river.

AN - 36405113; 806 AB - PURPOSE: Improvements to State Route 71 from the Holt Avenue interchange near Route 10 in the city of Pomona, Los Angeles County, California to Route 91 in Riverside County, California are proposed. Alternatives considered include No Build, an Expressway Alternative, and a Freeway Alternative. The Expressway Alternative would upgrade Route 71 to a multilane highway, primarily at-grade, with access at a limited number of major signalized intersections and interchanges. Proposed improvements include a new high-capacity eight-lane segment from the northern project limit at Holt Avenue to Route 60, a four-to-eight lane expressway segment from Route 60 to Route 91, selected grade separations and interchanges, and upgrading of the Route 60/Route 71 and Route 91/Route 71 interchanges. The Freeway Alternative would upgrade Route 71 to a multilane divided highway with full access control, that is, ingress and egress at interchanges only. Proposed improvements include roadway widening to accommodate six to eight lanes north of Route 60 and four to six lanes south of Route 60, selected grade separations, upgrading of the Route 60/Route 71 and Route 91/Route 71 interchanges, and provision for full interchanges to provide access along the corridor. In contrast to the No Build Alternative, the Expressway and Freeway alternatives would be consistent with and would support applicable transportation and land use plans. Both the Expressway and Freeway alternatives would be designed to provide for an acceptable level of traffic service; however, the expressway level of service is much lower than the freeway level of service in terms of operating speeds, capacity, access control, safety, and overall quality of flow. Total costs for the improvement of Route 71 are estimated to range from $100 million for the Expressway Alternative to $170 million for the Freeway Alternative. POSITIVE IMPACTS: Improvement of the Route 71 facility to full expressway and freeway standards would provide an acceptable level of traffic service and would serve planned development and growth in the Route 71 corridor area. NEGATIVE IMPACTS: Under the Expressway Alternative, from 36 to 37 residential buildings would be impacted by traffic noise in excess of federal guideline levels after the construction of sound attenuation barriers. Under the Freeway Alternative, noise levels exceeding federal guidelines would affect 117 residential buildings. Roadway widening and alignment adjustments would require the displacement of from 48 to 82 single-family homes, depending on the alternative, and the Freeway Alternative would displace an additional five retail stores, two medical offices, and additional commercial establishments. Both build alternatives would introduce new visual elements. Both the Expressway and Freeway alternatives would result in removal of approximately 140 acres of habitat area along the southern portion of the Route 71 corridor. A small portion of the federally proposed critical habitat for the rare least Bell's vireo would be impacted. Both alternatives would affect the Prado Flood Control Basin. Three archaeological sites would be directly impacted.

Preparation date: May 28, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COOPERATIVE AQUATIC PLANT CONTROL PROGRAM, CHARLESTON, SOUTH CAROLINA (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF NOVEMBER 1980). AN - 36399872; 794 AB - PURPOSE: Implementation of a cooperative program to control noxious aquatic plants within the state waters of South Carolina, in the interest of navigation, flood control, agriculture, fish and wildlife, public health, and related purposes, is proposed. Target species would include alligator weed, Brazilian elodea, water primrose, and any other species that significantly interfere with the use of public waters. Alligator weed would be controlled by an integrated program involving insects and herbicides, and Brazilian elodea and water primrose would be controlled by herbicides alone. Research for developing new methods of aquatic plant control would constitute part of the primary mission of the program. The purpose of this Supplemental Information Report is to provide for the control of additional aquatic plants and for the use of additional herbicides that may be certified for use on aquatic plants by the Environmental Protection Agency. POSITIVE IMPACTS: The reduction in dense growths of aquatic plants would improve drainage and navigation, reduce potential public health problems by shrinking mosquito breeding areas, improve recreational boating of infested waterways, and remove excessive cover and lessen vegetative consumption of dissolved oxygen to improve fishery habitat. Greater surface areas of water would be available for use by waterfowl. NEGATIVE IMPACTS: The large amount of decaying plant life resulting from each control operation could result in excessive organic buildup in bottom sediment, recycling of excessive amounts of nutrients into the water, and a temporary reduction in the amount of dissolved oxygen. Certain fish species would avoid areas treated chemically, resulting in a short-term curtailment of sport fishing in these areas. Some nontarget vegetation could be destroyed as a result of the treatments. LEGAL MANDATES: River and Harbor and Flood Control Act of 1965 (33 U.S.C. 610).

Preparation date: May 23, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MARYLAND ROUTE 100 EXTENDED, FROM INTERSTATE ROUTE 95 IN HOWARD COUNTY TO MARYLAND ROUTE 3/INTERSTATE 97 IN ANNE ARUNDEL COUNTY, MARYLAND. AN - 36402877; 810 AB - PURPOSE: Construction of Maryland Route 100 from Interstate 95 (I-95) in Howard County, Maryland to Maryland Route 3/I-97 in Anne Arundel County, Maryland is proposed. The project also includes improvements to sections of Maryland Route 176 from U.S. Route 1 to Maryland Route 295. The new east/west facility would provide adequate access to an area that Anne Arundel and Howard counties have designated for planned growth and would relieve existing congestion along major routes in the study area. Alternate 2, the Urban Arterial Alternative, proposes the construction of a curbed section urban arterial highway on or close to the alignment of existing Maryland Route 176 (Dorsey Road). From I-95, this alternate proceeds southeasterly, interchanges with U.S. Route 1, intersects with Race Road, and continues onto an interchange with Maryland Route 295. East of Route 295, it would follow existing Route 176, intersect with Maryland Route 713 (Ridge Road), and interchange with Maryland Route 170. East of Route 170, it would shift north of Dorsey Road to east of Maryland Route 652, where Option A would curve southeasterly, intersect with W.B.&A. Road, and then continue to the existing Maryland Route 100/Maryland Route 3 interchange; Option B would continue easterly from Route 652, remain north of Route 176 until just east of McPherson, where it would curve southerly through the western portion of Friendship Park, and then onto the Route 100/I-97 interchange. Alternate 3, one of the freeway alternatives, proposes the construction of Maryland Route 100 as a multilane freeway with full, controlled access from I-95 to I-97. From I-95 to Maryland Route 295, Alternate 3 would follow the same alignment as Alternate 2, with interchanges with U.S. Route 1, Race Road, and Route 295. East of Route 295, this alternative would curve southeasterly away from Dorsey Road, interchange with Maryland Route 713, and interchange with Maryland Route 170, just north of Munson Heights. East of Route 170, Option A would continue easterly, cross under Queenstown Road south of Jones Road, and interchange with I-97; Option B would curve northeasterly from the Route 170 interchange, cross under Queenstown Road, curve north of Burleytown and Alberta Heights, continue east across Friendship Park, and then curve southeasterly around Queenstown to the Route 100/I-97 interchange. Alternate 4, the second Freeway Alternative, proposes the construction of Maryland Route 100 as a multilane freeway with fully controlled access from I-95 to I-97 and the same alignment as Alternates 2 and 3 from I-95 through the U.S. Route 1 interchange. Before the alignment crosses the B&O Railroad, it curves northeasterly around the Parkway Valley Industrial Center I, curves southeasterly through the Patapsco State Park, and interchanges with Maryland Route 295. Alternate 4 then would continue southeasterly, interchange with an extension of New Ridge Road north of the Baltimore Commons Business Park, bridge over AMTRAK and Maryland Route 170, and cross through the southwest corner of BWI airport. After interchanging with Dorsey Road, Alternate 4 would follow the same alignment as does Alternate 2, Option A, to the Route 100/I-97 interchange. The Crossover Option (Alternate 3 to Alternate 4) proposes the construction of Maryland Route 100 as a multilane freeway with fully controlled access as proposed for alternates 3 and 4. It would utilize Alternate 3 from I-95 to Maryland Route 295 and then cross northeasterly to the Alternate 4 interchange with the New Ridge Road extension. The Crossover Option would then utilize Alternate 4 to the Route 100/I-97 interchange. POSITIVE IMPACTS: The proposed build alternatives would relieve congestion and improve accessibility to community facilities, parks, and public recreation areas by separating local and through traffic and by keeping the existing road network intact through the use of bridges. Planned growth would be accommodated by providing greater traffic capacity and improving access to and from the study area. There would be a positive effect on the tax bases of Howard and Anne Arundel counties. The accident rate within the study area would decrease even though higher transportation capacities would be attained. NEGATIVE IMPACTS: The proposed project would require between 29 and 42 residential relocations, of which 11 to 21 would be minority families, and from 7 to 12 business relocations. Some of the proposed routes would pass through existing developments, causing disruptions to the social interactions within these communities. All of the alternatives would adversely impact some wetlands. The use of stringent sediment control measures would minimize these impacts, and wetland reconstruction would be undertaken where practical. Noise impacts would occur due to increased traffic. As many as three archaeological sites might be impacted.

Preparation date: May 15, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - JAMESTOWN BRIDGE REPLACEMENT PROJECT, JAMESTOWN, NEWPORT COUNTY, RHODE ISLAND: STATE ROUTE 138 (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1981). AN - 36387489; 812 AB - PURPOSE: Replacement of the Jamestown Bridge and its approaches in Jamestown, Rhode Island is proposed. The bridge replacement is part of a project involving construction of 40 miles of Interstate 895 (I-895) from I-195 in Richmond, Rhode Island to I-95 in Swansea, Massachusetts. The proposed project would involve construction of two additional lanes on State Route (S.R.) 138 between S.R. 1A and the bridge. On the Jamestown side of the bridge, the four-lane highway would transition into the existing two-lane roadway west of Helm Street. The preferred alternative would be a controlled-access four-lane roadway along Eldred Avenue with interchanges at Helm Street and North Road and a new four-lane roadway west of East Shore Road, consisting of four 12-foot travel lanes, a 30-foot median (of which 24 feet would be grassed), 9-foot shoulders, and 30-foot landscaped clear areas. The length of the bridge and its approaches would be approximately 11,000 linear feet. POSITIVE IMPACTS: The bridge would constitute a major transportation link in southeastern Rhode Island for North Kingstown, Jamestown, and Newport. The structure would replace a substandard, two-lane crossing with a modern, four-lane facility that would provide an improved highway for through traffic, local access within existing neighborhoods, and community-wide access. Traffic safety would increase because buses would not have to cross the west half of S.R. 138. NEGATIVE IMPACTS: Bridge construction would encroach on the Plum Point Beach area in North Kingstown, and the bridge approaches would lie within a floodprone area. Rights-of-way requirements would result in displacement of one residence each in Jamestown and North Kingstown. The limited-access roadway would tend to make future development along the roadway less attractive owing to the lack of direct access to the roadway. Wetlands would be impacted because substantial quantities of fill would be required, resulting in the removal of 6.4 acres of wetland habitat, and because of new alignment locations and other roadway improvements. Some of the prime farmland (30.4 acres) would be adversely impacted.

Preparation date: May 14, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NORFOLK HARBOR AND CHANNELS, VIRGINIA: DEEPENING AND DISPOSAL (DAM NECK OCEAN DISPOSAL SITE) (SUPPLEMENTAL INFORMATION REPORT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1981). AN - 36399111; 828 AB - PURPOSE: Improvement of deep-water channels and anchorages in Hampton Roads, provision of additional improved anchorage areas in and adjacent to Norfolk Harbor, and disposal of dredged material taken from Hampton Roads are proposed as part of the developmental scheme for the Hamptom Roads port complex in Virginia. Channel improvements would include deepening of portions of the 45-foot channel to 55 feet, deepening of a portion of the 40-foot channel to 45 feet, and deepening of a portion of the 35-foot channel to 40 feet. A new Atlantic Ocean channel with a depth of 57 feet and a width of 1,000 feet would be dredged offshore of Virginia Beach. The final supplement to the final environmental impact statement would replace the originally proposed three sets of fixed mooring anchorages with a single circular anchorage, 55-feet deep with a 1,400-foot radius, in naturally deep water near Hampton. One anchorage at Sewell's Point would be improved by increasing its radius from 1,200 feet to 1,400 feet while maintaining its depth of 45 feet. The supplement specifically addresses the use of Dam Neck as a disposal site for dredged material to replace the disputed Suffolk disposal site. Under the new plan, dredged material from Thimble Shoal, Cape Henry, and the new Atlantic Ocean channels would be disposed of in the open ocean Dam Neck site, located 3.5 miles offshore of Virginia Beach. This supplemental information report (SIR) summarizes the results of field studies accomplished during the time period 1981-1985 by Federal Government agencies, state and university research laboratories, and private contractors. The main emphasis of the effort was to document the resources of the area and to reasonably assess the impacts associated with the proposed project. POSITIVE IMPACTS: The project would enhance the navigational quality of the port complex. Use of the Dam Neck disposal site would eliminate the extremely adverse consequences associated with use of the Suffolk site. The new site would allow disposal of up to 70 million cubic yards of uncontaminated sediments from the proposed channel dredgings. NEGATIVE IMPACTS: Dredging and disposal would cause temporary turbidity and destroy benthos, and the deepened channels could alter estuarine circulation in the lower Chesapeake Bay and Hampton Roads and increase salinity in the lower James River, allowing predators to invade oyster seed beds. Effective use of the Dam Neck disposal site would require enlargement from its current dimensions of 5,000 feet by 22,000 feet to 6,000 feet by 30,000 feet.

Preparation date: May 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TRINITY RIVER AND TRIBUTARIES, DALLAS, DENTON, AND TARRANT COUNTIES, TEXAS. AN - 36404721; 827 AB - PURPOSE: Cumulative impacts of development projects within the floodplains of the West Fork and Elm Fork of the Trinity River in the Dallas/Fort Worth metroplex are identified, and criteria for the issuance of future permits in this area are considered. For hydraulic purposes, the upstream boundary along the West Fork was determined to be Riverside Drive in Fort Worth and the upstream boundary on the Elm Fork is the Lewisville Dam. The downstream end of the study area is Interstate 635 (I-635) in Dallas. Five development scenarios are being assessed to determine criteria that would guide permit decisions. Under existing conditions, watershed and floodplain development as on the ground or permitted by February 1985 would provide the baseline and serve to calibrate hydraulic and hydrologic models. The Future Without Any Action would result in no changes in existing conditions, except that development of the urban watershed(s) is assumed to be complete. Changes in flood elevation due to increased runoff resulting from urbanization are identified, providing a basis for comparing the proposed scenarios. Maximum Development No. 1 represents a condition wherein all conveyance of floodwaters occurs between two levees set as closely together as possible. This condition would require a deep channel and minimum overbank areas inside the levees. All floodway fringe would be filled and developed. Along the West Fork, this levee system varies in width according to the slope of the river channel. A narrow levee system was also hypothesized for the Elm Fork in the area upstream of Sandy Lake Road. The area between Sandy Lake Road and I-635 was considered to be already under a maximum development condition. Maximum Development No. 2 also represents a condition in which all floodwaters are contained within a levee system; however, the overbank area would be much larger. The West Fork levee system was assumed to have an approximate width of 1,300 feet from inside toe to inside toe, as would the Elm Fork system upstream of Sandy Lake Road. The river segment between Sandy Lake Road and I-635 would be the same as in Maximum Development No. 1; only the width varies between the two scenarios. Under the 404 Permitting in Floodway Fringe Only scenario, the delineated floodway would not be allowed to change through the construction of levees or channel improvements; that is, there would be no construction within the floodway limits. All of the floodway fringe would be filled, and the valley storage provided by the floodway fringe would be lost. Five options, floodway extension, no floodway extention, existing, and a 100-foot or 200-foot bottom width pilot channel in the existing floodway were examined for this scenario. The No Further 404 Permitting scenario defines the most restrictive posture, in that the no floodplain development activities, either with the floodway or the floodway fringe, would be permitted by the Corps of Engineers (COE). Eighty percent of the floodway fringe not subject to COE regulations would still be susceptible to development, and the valley storage would be lost to the region. The Maximum Environmental Quality scenario was formulated to define the range of reasonably foreseeable futures. The hydraulic modeling was considered to be the same as the Future Without Any Action scenario. No permits would be issued by the COE in either the floodway or the floodway fringe, and local governments or the regional authority would prohibit any development in that portion of the floodplain outside COE jurisdiction. The Trinity floodplain and tributary system would be used for an urban greenway type project whose purposes could include flood control, water quality, recreation, open space, and fish and wildlife habitat. The floodplain could be used for flood conveyance, tertiary treatment of municipal wastewater, contouring and landscaping of disturbed areas, habitat preservation and enhancement, a trail network from Benbrook Lake to I-635, other flood compatible public recreation facilities, and groundwater recharge. POSITIVE IMPACTS: Development of a regional perspective would allow proper evaluation of the impacts of individual permit decisions. NEGATIVE IMPACTS: Under certain conditions, the Standard Project Flood would overtop the existing levee system in Dallas. Extensive modification of the river channel would impact water quality, in that minimum levels of dissolved oxygen would be shifted in both location and magnitude. Differential impacts on fish and wildlife resources, recreation, transportation planning, and solid waste disposal would also result.

AN - 36402384; 818 AB - PURPOSE: Implementation of a plan for clean-up of the Kesterson Reservoir, located in Merced and Fresno counties, California, is proposed. The Kesterson Reservoir is part of the 5,900-acre Kesterson National Wildlife Refuge. Studies have indicated that fish, waterfowl, sediments, and vegetation have been contaminated by selenium, most of which originated from irrigated agricultural drainwater carried via the 85-mile San Luis Drain (SLD). The general purpose of the Kesterson Program is to identify alternatives for the Kesterson Reservoir clean-up and land use, SLD clean-up and disposition, and wetlands mitigation. Under the Flexible Response Plan, vegetation would be harvested and incinerated on-site or hauled to a suitable disposal site. The preferred management option would be to supply Center Valley Project water conveyed via the north SLD, supplemented by local well water, to keep the ponds wet year-round. Levels of selenium and other contaminants in vegetation, invertebrates, soil, and groundwater would be monitored, and waterfowl hazing would continue. If water quality or biological monitoring indicates that this plan would not be successful, the Immobilization Plan would be implemented. Under the latter plan, air would be prevented from reaching the sediments by maintaining permanent ponds throughout the Kesterson Reservoir using clean water. New wetland habitat would be developed on adjacent land to offset the loss of historic wetland habitat at the Kesterson Reservoir. If monitoring indicated that the Immobilization Plan was also unsuccessful, the Wetland Restoration/Onsite Disposal Plan would be implemented, with concurrent monitoring. Under the Immobilization Plan, contaminated soils, sediments, and vegetation would be removed from Kesterson Reservoir and the entire SLD would be deposited in a 64-acre, double-lined and soil-capped landfill on-site. Following clean-up, soil would be imported and wetland habitat restored on the remainder of the Kesterson Reservoir. POSITIVE IMPACTS: Selenium leaching to groundwater would be reduced. Selenium volatilization would be reduced. All plans reduce the risks of off-site groundwater contamination. The Flexible Response and Immobilization plans reduce the risks of vegetation and wildlife contamination; the Wetland Restoration/Onsite Disposal Plan leaves little risk of contamination at the Kesterson Reservoir because contaminated soils, sediments, and vegetation would be removed. All plans would result in reduced long-term exposure to public health risks. NEGATIVE IMPACTS: The Flexible Response and the Immobilization plans carry significant risks of continued vegetation and wildlife contamination, since providing substitute habitat would not necessarily prevent wildlife species from using the Kesterson Reservoir and becoming contaminated. The alternatives would create short-term increases in public health risks during construction. Under the Flexible Response and Immobilization plans, hazing noise would continue. Both alternatives would cause visual impacts from hauling of either vegetation or sediments.

AN - 36393153; 761 AB - PURPOSE: Construction of an extension of State Route 386 from Interstate 65 (I-65), approximately 1.1 miles south of the Two Mile Pike interchange to the Hendersonville Bypass east of Center Point Road in Davidson and Sumner counties, Tennessee is proposed. The new highway would be a four-lane divided, access-controlled facility with grade-separated interchanges at access points. The proposed design would consist of four 12-foot traffic lanes, with a 14-foot median on a 200-foot minimum right-of-way. Major structures would be required over I-65 and Two Mile Pike. The approximate length of the project is 4.2 miles. POSITIVE IMPACTS: By connecting I-65 and the Hendersonville Bypass, the new highway would enhance route continuity and would improve local and regional accessibility. Traffic congestion on existing highways would be reduced, and safety and operating conditions in the transportation corridor would be improved. The project would also complement future planned growth and development in the area. NEGATIVE IMPACTS: The new highway would displace seven residences and six businesses and would reduce the amount of wildlife habitat. It also would introduce air and noise pollution to the area and would create a visual intrusion on isolated and residential areas. There would be temporary construction impacts such as fugitive dust, open burning, equipment noise, inconvenience to motorists, and temporary siltation to streams. One historic site and one archaeological site could be affected.

AN - 36384957; 756 AB - PURPOSE: Construction of a transportation facility in the Route 85 transportation corridor between Route 101 in south San Jose and Stevens Creek Boulevard in Cupertino, California, a distance of approximately 18 miles, is proposed by the California Department of Transportation (Caltrans). Nine alternatives are presented. (1) No project. (2) Transportation System Management (TSM): Low-cost projects to improve and upgrade the existing transportation facilities, both roadway and transit. (3) Light Rail Transit (LRT): A grade-separated light rail facility that would extend northerly from the State Route 85/87 (Guadalupe Corridor) interchange to a terminus in the vicinity of Stevens Creek Boulevard in Cupertino in the northwest. This alternative would also extend the Route 85 highway element of the Guadalupe Corridor Project from Miyuki Drive to Route 101 in south San Jose. (However, the transit plan extends from Miyuki Drive in south San Jose to the CalTrain station in Mountain View.) (4) A four-lane freeway with LRT: A grade-separated, access- controlled four-lane freeway with LRT in the median. (5) A four-lane freeway with LRT and HOV: A grade-separated, access-controlled four-lane freeway with LRT in the median and a High Occupancy Vehicle (HOV) lane between the LRT and first mixed-flow traffic lane. (6) A four-lane freeway with bus /HOV transitway: A grade-separated, access-controlled four-lane freeway with a bus/HOV transitway in the median. (7) A six-lane freeway with bus/HOV transitway: A grade-separated, access-controlled six-lane freeway with a bus/HOV transitway in the median. (8) An eight-lane freeway: A grade-separated, access-controlled eight-lane freeway with a median wide enough for an LRT system or future freeway widening for mixed-flow of bus/HOV lanes. (9) An eight-lane freeway with LRT: A grade-separated, access-controlled eight-lane freeway with LRT in the median. The base profile total cost ranges from $70 million for the TSM to $530 million for the four-lane freeway with HOV and LRT or the eight-lane freeway with LRT. POSITIVE IMPACTS: All of the alternatives would improve the existing transportation network, with the major transportation alternatives impacting it to a much greater degree than either the TSM or LRT. NEGATIVE IMPACTS: The No Project alternative would worsen existing conditions by further congesting the already overcrowded facilities. The proposed construction alternatives would encroach on floodplains in the Route 85 corridor. There would be a loss of approximately 9.6 acres of wildlife habitat with any of the highway alternatives. The LRT-only alternative would result in a loss of approximately 4.8 acres of wildlife habitat. All of the alternatives would result in an increase in the current noise levels along the Route 85 transportation corridor. Three structures that are eligible for the National Register of Historic Places would be removed. There would be impacts to five parks, one recreational area, one wildlife refuge, and three historical properties.

Preparation date: April 22, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DEVIL'S SLIDE IMPROVEMENTS, ROUTE 1 FROM HALF MOON BAY AIRPORT TO LINDA MAR BOULEVARD, SAN MATEO COUNTY, CALIFORNIA. AN - 36403172; 755 AB - PURPOSE: Improvement and/or relocation of a segment of Route 1 in the vicinity of Devil's Slide in San Mateo County, California are proposed to prevent future closure of the road due to landslides and ocean wave action. The preferred Martini Creek Alignment Alternative, would be a two-lane facility with slow vehicle lanes in the uphill direction where grades are six percent or greater, with additional mitigation measures including a vehicle recovery area and vehicle retention facilities (escape ramps) in the downhill direction. The California Department of Transportation (Caltrans) concluded that the two-lane option with slow vehicle lanes in the uphill direction only would not provide the needed safety features in the downhill direction. Caltrans therefore proposed the additional mitigation measures to provide an adequately safe solution to the Devil's Slide problem, while offering a shorter and less expensive bypass alignment. Measures to provide optimum highway safety and to minimize adverse environmental impacts include a bridge over Martini Creek; a bridge at Green Valley to reduce the amount of fill; shifting the section of alignment north of the summit (within the rights-of-way) southwesterly to reduce the amount of fill; a series of detention basins to regulate peak downstream flows in the Sanchez Creek watershed; grading a small pond to retain natural runoff for wildlife on the west side of the highway, south of Shamrock Ranch; a retaining wall and a structure at the Shamrock Ranch to reduce impacts to the ranch; constructing an undercrossing at San Pedro Terrace Avenue/San Pedro Road instead of closing both roads at Route 1; a frontage road from San Pedro Road to Linda Mar Boulevard on the west side of Route 1 for better access to the San Pedro Point subdivision; and a bridge at San Pedro Creek. Construction costs are estimated at $37 million for 4.5 miles of improvements. POSITIVE IMPACTS: The preferred alternative would provide the lowest projected accident rate north of Martini Creek. This alternative provides an efficient and safe highway bypass of the geologically active area of Devil's Slide, and it is consistent with the state coastal management program and San Mateo County's Local Coastal Program. It offers the least impact on the natural environment of all the bypass alternatives. NEGATIVE IMPACTS: The preferred alternative would produce large cuts and fills on San Pedro and Montara mountains. Approximately eight acres of prime farmland would be taken directly and two acres indirectly; approximately three and one-half acres of riparian land would be taken, as well as a substantial portion of one unique plant community and several candidate species. A total of 330 acres would be needed for rights-of-way, of which the state owns 200 acres, leaving 130 acres to be acquired. Traffic would increase on existing Route 1, with adverse effects on Montara and Moss Beach. There would be more fog at higher elevations from June to September, reducing visibility on the existing roadway. Home range for large mammals would also be reduced and a barrier to migration would result, although mitigation measures would reduce these impacts. LEGAL MANDATES: Coastal Zone Management Act of 1973, as amended (16 U.S.C. 1451 et seq.), Department of Transportation Act of 1966 (49 U.S.C. 1651 et seq.), Executive Order 11988, and Federal Aid Highway Act of 1968 (23 U.S.C. 128(a)).

AN - 36400301; 757 AB - PURPOSE: Construction of a new four-lane divided roadway, 25.35 miles in length, extending from State Route (S.R.) 316 northeast of Lawrenceville to S.R. 10/U.S. 78 west of Athens, Georgia is proposed. This arterial would be a partially controlled access facility on a minimum of 300 feet of rights-of-way and would carry a design speed of 60 mph, 3 degree maximum curvature, and 3-percent maximum gradient. The extension would travel in an easterly direction on new location, would parallel the Colonial Gas Pipeline, and would then cross Dacula and Kilcrease roads south of Dacula. The roadway would cross Patrick Mill Road, S.R. 324, S.R. 81, S.R. 11, and S.R. 53 as it passes south of Fort Yargo State Park and north of the city of Bethlehem. This alignment would also pass through the southern portion of Statham and would cross S.R. 324 and Barber Creek Road before connecting with U.S. 78/S.R. 10 south of Bogart to its terminus. All major roads would be crossed at-grade. The estimated cost of the build alternative is $60.2 million. POSITIVE IMPACTS: Air quality would be in compliance with state and federal Ambient Air Quality Standards. The project is part of an overall plan to improve air quality in the region. Traffic would be reduced on parallel federal and state routes. The project would help reduce accidents on S.R. 8/U.S. 29 and would improve vehicle efficiency for commuters and local users. NEGATIVE IMPACTS: Ten residences would experience noise levels in excess of noise abatement criteria. Traffic would increase on intersecting routes. Six potential properties eligible for the National Register of Historic Places might be affected, and 13 residences would be displaced. Five wetlands and some farmland would be impacted.

Preparation date: April 16, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MIDDLE GRAVE CREEK WATERSHED PLAN, MARSHALL COUNTY, WEST VIRGINIA. AN - 36396380; 783 AB - PURPOSE: A watershed protection plan is proposed for the 18,900-acre Middle Grave Creek Watershed, Marshall County, West Virginia. The preferred plan would incorporate channel work and land treatment measures. Channel work would occur along 4,820 feet of the Middle Grave Creek and would consist of enlarging the channel to a bottom width of 70 feet while maintaining the present depth of 6 feet. The capacity of the 12th Street bridge would be enlarged to accommodate the improved channel flow and to improve outlet conditions. Land treatment would consist of conservation practices on 100 acres of cropland, 120 acres of hayland, 1,000 acres of pastureland, 10 acres of urban developed land, and 10 acres of miscellaneous land. Conservation practices would include conservation cropping systems, crop residue management, conservation tillage, pastureland and hayland management, pastureland and hayland planting, critical area plantings, spring developments, and land use conversion or change. The total project cost is estimated at $2.0 million, and the average annual cost is estimated at $173,000. POSITIVE IMPACTS: Flood damages would be reduced for 407 residences, 14 businesses, and 2.3 miles of streets. Agricultural productivity would be enhanced and water quality would be improved. Accessibility to emergency services also would be improved, and driving hazards would be reduced. The project would provide 86.7 man-years of employment. NEGATIVE IMPACTS: The project would require approximately 10.5 acres of land for installation, including an average width of 20 feet of backyards at 15 residences in Maxwell Acres. In addition, 13.4 acres would be required for temporary construction easements and maintenance rights-of-way. Approximately 4,820 feet of Middle Grave Creek and associated aquatic and riparian habitat would be altered. The loss of large shade trees and decorative shrubs along the creek would decrease the visual quality of the landscape. Stream erosion, turbidity, noise, and air pollution would increase temporarily during project construction. Flood damages would not be eliminated entirely.

Preparation date: April 15, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NATIONAL FREEWAY--U.S. ROUTE 48, SECTION I, WOLFE MILL TO M.V. SMITH ROAD, ALLEGANY COUNTY, MARYLAND (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF AUGUST 1980). AN - 36403220; 759 AB - PURPOSE: Construction of the final 19-mile gap of the National Freeway from Wolfe Mill Road to M.V. Smith Road in Allegany County, Maryland is proposed. The preferred alternative generally follows existing U.S. Route 40 and consists of major reconstruction to provide a four-lane divided highway with full control of access and a minimum median width of 34 feet. Where the existing pavement and cross-section are satisfactory, existing U.S. Route 40 would be retained as part of the freeway. In three areas, however, upgrading of U.S. Route 40 to current design standards within its existing corridor would cause substantial impacts on residences and businesses and would be extremely expensive. Therefore, the preferred alternative deviated from the existing U.S. Route 40 in these areas, as follows: (a) between Wolfe Mill and Hinkle roads, (b) the summit of Martin Mountain, and (c) between Flintstone and the summit of Polish Mountain. In order to provide continuity of local traffic circulation after construction of the freeway, a continuous two-way frontage road would be provided between Wolfe Mill and Fifteen Mile Creek roads, consisting of portions of existing U.S. Route 40, Old National Pike, Wilson Road, and Murley Branch Road, as well as a new roadway. Interchanges would be provided at Wolfe Mill Road, Rocky Gap State Park, Martin Mountain, Flintstone, Fifteen Mile Creek Road, and M.V. Smith Road. POSITIVE IMPACTS: Completion of the National Freeway would provide a controlled-access highway between Morgantown, West Virginia and Hancock, Maryland and would improve economic conditions for western Maryland and the Appalachian Region. The level of service would improve, and accident rates would decline. NEGATIVE IMPACTS: Under the preferred alternative, 37 residences would be acquired and five businesses would be displaced. Three farms would be affected, with one being displaced. The preferred alternative would require 15 acres of Rocky Gap State Park, 53 acres of Greenridge State Forest, and land from three historic sites. Eight archaeological sites would be affected. Noise levels would exceed Federal Noise Abatement Criteria at 19 sites.

AN - 36399028; 780 AB - PURPOSE: The final environmental impact statement (FEIS) proposed a recommended plan to replace Lock and Dam 7 (L&D 7) on the Monongahela River at Greensboro, Greene and Fayette counties, Pennsylvania with a new lock and dam to be built 2.8 miles downstream, near the community of Grays Landing. The FEIS was prepared as part of a feasibility study that also included the addition of a lock landward of the existing lock at Lock and Dam 8 located at Point Marion, Pennsylvania. These two projects have since been separated to facilitate subsequent detailed study and reporting requirements. The present L&D 7 is located at river mile 85.0. The structure consists of a single 56-foot by 360-foot lock that was completed and put into service in 1925. With its fixed crest, L&D 7 establishes a 15-foot lift between pools. The existing Maxwell Pool at elevation 763 feet above the National Geodetic Vertical Datum (NGVD) would be shortened by 2.8 miles, and the existing Pool 7 at elevation 778 feet above NGVD would be extended downstream the same distance to the new dam. There would be no change in the pool elevation upstream of existing L&D 7, which would then be removed. The new L&D 7 would be an 84-foot by 720-foot lock chamber and a fixed-crest dam. This supplemental information report addresses potential modifications to the Grays Landing Lock and Dam project, which would consist of moving the project site 1,000 feet downstream and increasing the amount of right bank excavation upstream of the site. POSITIVE IMPACTS: Replacement and rehabilitation of the navigation structure would preclude the need to partially close the Monongahela River navigation system. Preservation of the system in its existing condition would help support local industries and the general economic base of the region. NEGATIVE IMPACTS: The proposed modifications would increase the land requirements at the project site, extending the project area both upstream and downstream. The increased bank excavation would require the use of an off-site disposal area. Raising the pool between river miles 82.2 and 85.0 would damage five archaeological sites. Thirteen residences and one business would be displaced.

Preparation date: April 4, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - KINGFISHER AND UNCLE JOHN CREEKS LOCAL FLOOD PROTECTION PROJECT, KINGFISHER, OKLAHOMA. AN - 36396337; 778 AB - PURPOSE: Implementation of a plan to alleviate flooding problems along the Kingfisher and Uncle John creeks at Kingfisher, Oklahoma is proposed. The city of Kingfisher is located 40 miles northwest of Oklahoma City. Kingfisher Creek originates southwest of the city of Kingfisher and flows in a northeasterly direction into the Cimarron River. Uncle John Creek, a principal tributary of Kingfisher Creek, originates south of the city of Kingfisher and joins Kingfisher Creek immediately north of the city. The recommended plan of improvement would consist of a U-shaped, earthen levee, in combination with an 850-foot concrete floodwall. The levee and floodwall would total 14,975 feet in length. Three ponding areas, totalling 28 acres, would be inside the levee and floodwall to catch interior drainage from the 25-year storm event over the city. A total of five roads or highways, accessing the city from the north, east, and west, would need to be modified to accommodate the levee and floodwall plan. The tracks of the Oklahoma, Kansas and Texas Railroad, which serves the city, would also need to be modified. Kingfisher and Uncle John creeks would be cleared and snagged of all trees and debris for a total of 2.54 miles, and flowage easement would be acquired on 360 acres of land. The project first costs are estimated at $7.5 million. The total average annual costs are estimated at $700,000; the average annual benefits are $914,780, producing a benefit to cost ratio of 1.3. POSITIVE IMPACTS: The proposed plan would increase property values, provide standard project flood protection, and reduce human suffering and anxiety caused by flooding. NEGATIVE IMPACTS: Removal of approximately 50 acres of riparian woodland would be required along Kingfisher and Uncle John creeks. To mitigate this effect, 30 acres of trees and shrubs would be planted in designated areas along the levee and interior ponding areas. The construction of the levee and ponding areas and the planting of trees and shrubs would require the acquisition of approximately 43 acres of prime farmland. One commercial and 14 residential structures would require relocation. Wildlife would be affected both upstream and downstream from the project. In addition to the loss of terrestrial wildlife habitat in the project area from project construction, flood protection provided by the project would accelerate development and result in additional reduction of available habitat.

Preparation date: April 4, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - CORTE MADERA CREEK FLOOD CONTROL PROJECT, UNIT 4, TOWN OF ROSS, MARIN COUNTY, CALIFORNIA (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF FEBRUARY 1979). AN - 36386294; 772 AB - PURPOSE: Construction of flood control measures for Corte Madera Creek in Marin County, California is proposed. The preferred alternative as presented in this supplement is the 1985 Floodwall Plan. This plan would require construction of 2,450 feet of floodwalls (1,080 feet on the right bank and 1,370 feet on the left bank) between Corte Madera Creek and the residences on Sylvan Lane and Sir Francis Drake Boulevard. The Lagunitas Road Bridge would have to be replaced. A 270-foot reach of reinforced concrete channel would be constructed from the terminus of the existing flood control channel to the proposed sediment trap. A 3-foot-wide low-flow notch would be constructed along the channel centerline to facilitate fish passage. Four pools would be spaced at 60-foot intervals to provide resting areas for fish during migrations. A 270-foot-long sediment trap, designed to accommodate 3,200 cubic yards of material would be constructed. Rehabilitation of fish rearing areas above the Lagunitas Road Bridge would be performed within the affected reach. Additionally, biotechnical bank stabilization measures would be utilized along portions of the bank. Under this alternative, residences in and downstream of Unit No. 4 would be provided full Standard Project Flood (SPF) protection, and existing flood control features of the downstream units would become fully functional. POSITIVE IMPACTS: The completed project is expected to significantly reduce erosion and subsequent sedimentation in the study area. It is also anticipated that the sedimentation rate below the bridge and into Units 1, 2, and 3 would be significantly reduced. As a result, the functioning of the downstream flood control features would be enhanced. In the area downstream of the study area, no future damages are expected from the SPF. Within the study area, the flood control walls would protect a number of private homes, public buildings, and public facilities. The preferred alternative would have substantial long-term positive benefits on traffic since the roadway would no longer be subjected to periodic flooding. The level of flood protection afforded properties under this alternative would significantly reduce the costs of repairing flood damage and providing clean-up. NEGATIVE IMPACTS: Two homes not protected by the floodwalls would be removed. The principal long-term impacts on aesthetic quality would be the substitution of the natural channel with concrete in the downstream reach and the substitution of portions of the natural bankline above the bridge with riprap. Homeowners along the creek would be impacted by restriction of access and views caused by construction of concrete floodwalls in their backyards. A net loss of riparian woodland would occur below the bridge. The Lagunitas Road Bridge, which is a National Register of Historic Places property, would be replaced with a new bridge. The project would produce a net loss in abundance, diversity, and density of tree and shrub species. The degradation of water quality caused by the removal of vegetative cover and shade trees near the stream would have a slightly adverse impact on the benthos in the concrete channel section. Long-term impacts to amphibians and reptiles would include a net loss in available habitat. Mammals would be impacted by the disruption of travel corridors caused by the concrete channels and stabilized banks. Arboreal mammals would be impacted by the loss of 333 trees. Long-term impacts of the project would also include a net loss of fish spawning and rearing habitat resulting from the construction of 630 feet of concrete-lined channel below the Lagunitas Road Bridge and extensive revetments above the bridge.

Preparation date: April 4, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - UNOCAL (UNION OIL COMPANY OF CALIFORNIA) PARACHUTE CREEK, PHASE II, SHALE OIL PROGRAM, GARFIELD COUNTY, COLORADO. AN - 36392762; 742 AB - PURPOSE: Union Oil Company of California (UNOCAL) is pursuing phased development (Phase II) of its oil shale holdings in the Parachute Creek area, to the north of the town of Parachute, in Garfield County, Colorado. Construction of the approximately 10,000 barrels per day (BPD) Phase I operation was completed in late 1983. Phase II would add 80,000 BPD to raw shale oil production. UNOCAL has submitted an application for a Section 404 Permit to place fill material in the mainstem of Parachute Creek to construct a reservoir for Phase II operations. Major Phase II project components would include: (1) a new room-and-pillar underground mine and crushing facility at Old Mountain and expansion of the permitted Phase I mine at Long Ridge; (2) new shale handling and surface retorting facilities with the capacity to produce 80,000 BPD of raw shale oil on Old Mountain; (3) expansion of the permitted Phase I upgrading plant in four steps; (4) a water supply system; (5) an expanded common pipeline corridor from the Colorado River through Parachute Creek Valley to the top of Old Mountain; (6) a retorted shale disposal system; (7) a connecting pipeline to transport syncrude from the upgrading plant to an existing crude oil pipeline or to any future joint-industry pipeline; (8) a natural gas supply system to the upgrading plant; (9) an extension of UNOCAL's 230 kV power transmission line to Old Mountain and to the intake and settling basin sites; and (10) associated road development or improvement. The Unishale C process is the proposed retorting method for Phase II. Two general locations for retorted shale disposal were selected in the screening analysis: East Fork Canyon and Old Mountain. All product pipeline alternatives would begin at the upgrading plant. The end points of each alternative route are as follows: (a) LaSal pipeline origin; (b) Shale Oil Pipeline Study origin; (c) Lisbon, Utah; (d) Lisbon, Utah; (e) Rangeley, Colorado; and (f) Casper, Wyoming. UNOCAL may consider construction of a loop to its existing 230 kV power transmission line, and three alternate routes have been considered for this loop. POSITIVE IMPACTS: Material outputs would be approximately 84,000 BPD of syncrude, 250 tons per day (TPD) of sulfur, and 300 TPD of ammonia. Each barrel of shale-derived syncrude, because of its higher yield of distillate products, would offset the importation of approximately 1.2 barrels of foreign crude oil. Hiring of the operational work force would begin in 1988 and would reach its maximum of 2,600 workers in 1996. A 61 percent increase in total personal income in Garfield County is projected, due directly to the Phase II expansion. Projected revenues from the Phase II expansion should generate sizable fiscal surpluses for Garfield County and School District No. 16 after 1988. NEGATIVE IMPACTS: A total of approximately 600 million tons of retorted shale would be produced over the life of the project. Major hazardous wastes produced by Phase I and Phase II would be 10,000 to 15,000 tons /year of spent arsenic catalyst and a total of 1.2 million tons of deasher sludge. Under normal operating conditions, emissions from the upgrading plant could be at odoriferous concentrations in the town of Parachute under highly infrequent worst case meteorological conditions. Vegetation clearing during site preparation would result in a significant, short-term increase in soil erosion rates. Assuming that the proposed Parachute Creek dam and reservoir would be left in place at project termination, approximately 127 acres of topsoil would be permanently inundated. It is estimated that approximately 50,000 tons per year of sediment would be trapped in the proposed reservoir, given the current reservoir outlet design. Significant impacts from vegetation clearing would include the loss of 51 acres of riparian woodland in the East Fork Canyon and 46 acres of riparian woodland in Parachute Creek Valley, resulting from construction of the retort/mine access road and Parachute Creek dam and reservoir, respectively, as well as the loss of 331 acres of aspen forest resulting from placement of retorted shale on Old Mountain. Leachate would have a significant impact on biota. Garfield County would experience a significant negative impact in one year (1986), in which a major capital outlay would be required for expanded prison facilities.

Preparation date: April 3, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - QUILLAYUTE RIVER, WASHINGTON NAVIGATION PROJECT, OPERATIONS AND MAINTENANCE. AN - 36392959; 782 AB - PURPOSE: Maintenance dredging is proposed for the Quillayute River Navigation Project at La Push, Washington. The project consists of a small boat basin with a timber training wall, a rubblemound jetty, a rubblemound dike, a navigation channel, and maintenance of Quillayute Spit. Under the preferred alternative, the structural portions of the project would be maintained as in the past, while dredging would be performed by a combination of hydraulic pipeline dredges and mechanical means, such as clamshell dredges, agitation dredges, or land-based backhoes. Material dredged by hydraulic means would be deposited on the ocean side of the upper spit or in a designated Quileute tribal upland site. Material dredged mechanically would be mixed into the water column and carried downstream by the river until it settled back to the bottom in deeper water or it would be loaded onto barges or trucks and disposed of at an upland disposal site. Backhoe dredging to remove material from the basin entrance, would be performed at low tide from the river bar on the east side of the training wall in conjunction with hydraulic or clamshell dredging. Agitation dredging would occur only in the navigation channel. Generally, hydraulic dredging would be performed between February 1 and March 31 of any year, while mechanical dredging could occur between June 1 and March 31. POSITIVE IMPACTS: The preferred alternative would meet the principal objective of protecting and maintaining the navigation project while minimizing disruptions to salmon fisheries resources. A monitoring program would guarantee that fish entrainment did not exceed levels set by the Quileute tribe. NEGATIVE IMPACTS: Because the preferred plan would involve upland disposal in some situations, double or triple handling of the dredged material would be necessary, increasing the overall annual cost of maintenance and dredging operations. Removal of benthic organisms from the river channel and boat basin would occur. Maintenance operations temporarily would increase noise levels and water turbidity.

Sampling was conducted to describe water quality and fish and benthic macroinvertebrate populations associated with dike, revetment, and abandoned channel habitats. Water quality measurements were rather uniform, except for some small occurrences between some measurements made in the abandoned channels and those in the main river, indicating a well-mixed system. Thirty-nine fish species comprised the juvenile and adult catch. The revetted bank samples were dominated by larger species, such as the blue sucker and flathead catfish. The dike field had a similar assemblage of larger species with blue sucker, channel catfish, flathead catfish, and goldeye predominating. The dike fields also provided habitat for a wide variety of minnows. The abandoned channels yielded the greatest species richness and overall greatest numbers of fish. The overall abundance of fish larvae in the abandoned channels was much higher than in the main channel and the catch was dominated by sunfishes and gizzard shad. The main channel habitats were found to be of importance for freshwater drum, carp suckers, and common carp. Peak times of larval fish abundance occurred between early June and mid-August. There were differences in the densities and taxonomic composition of the benthic invertebrate communities in the different habitats. The abandoned channel habitats were characterized by fine sediment particles, high benthos densities, and lower number of taxa than found on the rock substrate of the dikes and revetments. The dike pool habitats were characterized by high current velocities, a diversity of sediment types, and low benthic diversity. The dikes and revetments were similar in having large rock substrates and high current velocities. Attached forms such as Hydra were important as were other invertebrates commonly associated with coarse substrates (caddisflies, stoneflies, and clinging mayflies).

A model study of the original channel control structure was conducted to develop a satisfactory design for discharges up to 10,000 cfs. Since the construction of the original control structure, the channel has degraded 11 ft and flows exceeding 10,000 cfs have occurred regularly. Flows exceeding the berm height scoured the side slopes causing the riprap to fail, and convergence of the concentrated flows from the right and left bank berm sections caused the development of a severe scour hole downstream of the stilling basin. High flows during the spring of 1983 caused the structure to fail so another model investigation was necessary to develop a design for the replacement structure and to determine methods to stabilize the area downstream of the structure and the channel side slopes. Tests on a 1:25-scale hydraulic model of the replacement structure were conducted to develop the design. The model reproduced about 650 ft of topography upstream from the structure, the control structure, and 1,150 ft of topography downstream from the structure. Modifications to the original design were made to produce a structure that provided an acceptable headwater rating curve, and one with adequate energy dissipation in the stilling basin. A notched weir was developed that provided a desired range of headwater elevations for the expected discharges. The weir also produced velocities upstream and downstream from the low-flow notch for discharges less than 1,000 cfs that were considered appropriate for upstream fish migration. Stable riprap designs were determined for the channel bottom downstream from the stilling basin and the channel side slopes.

This is particularly true for monolith joints in hydraulic structures such as concrete dams and navigation locks. Embedded waterstops are generally used to prevent water passage through the monolith joints of such structures. A waterstop failure can result in various problems ranging from minor leakage with cosmetic concern to significant hydraulic forces and structural overloading which could threaten the stability of a structure. The primary objective of this study was to identify materials and techniques which have been used in repair of waterstop failures. Also, based on review and evaluation of current practices, a secondary objective was to identify those areas where research is needed to supplement existing technology. Leakage through monolith joints ranged from minor flows to more than 600 gal/min. In general, leakage was the result of waterstop defects including (a) excessive movement of the joint which ruptures the waterstop, (b) honeycomb areas adjacent to the waterstop resulting from poorly consolidated concrete, (c) contamination of the waterstop surface which prevents bond to the concrete, (d) puncture of the waterstop or complete omission during construction, and (e) breaks in the waterstop due to poor or no splices. More than 80 different materials and techniques have been used, individually and in various combinations, to repair the waterstop failures reported here. Some appear to have been successful, while many have failed. Because of a lack of appropriate test methods and equipment, most materials have been used in prototype repairs with limited or no laboratory evaluation of their effectiveness in the particular application. A definite need exists for development of testing procedures and equipment to allow systematic laboratory evaluation of waterstop repair techniques prior to application in prototype structures.

Each review covers one of the following four broad wetlands functions and values: (1) water quality, (2) fish and wildlife habitat, (3) socioeconomics, and (4) hydraulics. The four reports, along with other information, were used to develop a multiyear wetlands functions and values research study plan implemented by the US Army Engineer Waterways Experiment Station. This report examines the literature on water quality functions of wetlands. Study results indicated considerable diversity in the quantity and quality of wetlands water quality literature between and within each geographic region of the coterminous United States and Alaska. In general, wetlands water quality has been studied most intensely in the estuarine marshes of the Gulf and North Atlantic coasts. Water quality in freshwater wetlands has not received attention commmensurate with the wide distribution of these wetland types. Most previous wetlands water quality research has been fragmented into site-specific or function-specific studies. Very few mass balance studies have been conducted. Two complementary approaches to addressing wetlands water quality research data gaps are recommended. The first approach is to develop mass balances or budgets of carbon, nutrients, heavy metals, and other possible pollutants. The mass balance studies should be determined at carefully selected field sites over several annual cycles. The second approach would focus on the design, construction, and use of experimental wetland microcosms. The microcosms would permit assessment of the fates and effects of various materials under highly controlled conditions.

Major water quality differences among habitats were related to the presence or absence of current. Continual flow and high turbulence in lotic habitats such as the main channel and permanent secondary channel resulted in high suspended solids concentrations, high turbidities, low water transparencies, and low light penetration. Such physical characteristics resulted in low algal biomass, more stable pH and dissolved oxygen levels, and the constant availability of algal nutrients. In contrast, lentic areas, such as the abandoned channel at most river stages, and the dike fields at low flows, had relatively lower suspended solids and increased water clarity. This resulted in high algal biomass, higher pH readings, frequent dissolved oxygen supersaturation in surface waters, and nutrient depletion in slack-water areas. The distribution of macroinvertebrates in the lower Mississippi River is a function of the physical characteristics of the system, notably current velocity and substrate composition. Three principal factors determine ichthyoplankton composition and distribution: larval phenology, habitat characteristics, and river stage. These studies have shown that the abandoned channel and dike field pool habitats are of special concern and importance. The placement of dikes and revetments along the river has prevented channel meandering by ' locking ' the river into a permanent alignment. Consequently, abandoned channels are rarely created now. Existing abandoned channels should therefore be protected from filling in or being dewatered. The formation of lake-like pools in the dike fields during low flow is precluded by the filling in of these areas. Engineering practices which would prevent or delay the'terrestrialization ' of dike fields should be encouraged in the lower Mississippi River.

Thus, the environmental factors controlling the size distributions of planktonic autotrophy (algal photosynthesis) and microheterotrophy (bacterial heterotrophic activity) are of considerable ecological interest. To examine hypotheses regarding their environmental control, the author compared the size distributions of planktonic autotrophy and microheterotrophy within and between oligotrophic DeGray Reservoir (Arkansas) and eutrophic West Point Reservoir (Alabama-Georgia). Naturally occurring assemblages of reservoir phytoplankton and bacterioplankton and radiolabeled with sodium 14-C-bicarbonate and sodium 3-H-acetate and were size-fractionated by filtration through polycarbonate membrane filters. Planktonic autotrophy in both reservoirs was dominated by microalgae, with usually >60% of the total photosynthetic carbon uptake associated with organisms in the 80% of the planktonic microheterotrophy. Relative to marked uplake-to-downlake gradients in physical and chemical conditions , size distributions of autotrophy and microheterotrophy were remarkably uniform in both reservoirs. The results suggest that additional ecological factors (e.g., size-selective losses of cells by grazing and/or sinking, autograph-microheterotrophy interactions) must be considered, in addition to the availability of nutrients and suspended particles, as potential environmental controls on the size distributions of planktonic autotrophy and microheterotrophy.

This report provides a literature review of reservoir internal mixing processes, in which general transport processes, reservoir mixing processes and their effect on water quality, and one-dimensional predictive techniques and computer algorithms are presented and analyzed. The historical development of the recommended predictive techniques, including the assumptions, limitations and advantages of the techniques used in the development, is also documented. The recommended one-dimensional mixing algorithm is generalized with respect to CE reservoirs and is not constrained by extensive data requirements nor limited in the mixing processes considered. The algorithm includes all major mixing processes in order to predict changes in the reservoir 's mixing regime resulting from changes in hydrometeorological conditions and project operation. The recommended algorithm was used to simulate the thermal structure of over 15 reservoirs and lakes of varying geographical locations, size, hydrometeorological regime, and operational configurations. The recommendations for the mixing algorithm are the opinions of the authors, and all phases of it are not necessarily incorporated in the current one-dimensional CE reservoir model (CE-QUAL-R1).

Data were collected on the Lower Mississippi River between river miles 440 and 448. Some gear types were used to test diel variations in the macroinvertebrate communities while others were used to obtain information on community structure and seasonal variation at dike, revetment, and sandbar habitats. All gears evaluated, with the exception of the electroshocker, were successful to some degree in sampling the macroinvertebrate fauna which colonized the dike and revetment structures in the areas investigated. The diaphragm pump is effective in sampling the macroinvertebrate fauna that colonized the dike structures and is effective in detecting diel and location (upstream versus downstream) differences in macroinvertebrate community composition. Both circular basket implants and rocks used to sample the dike and revetment structures are efficient techniques for sampling these habitats. Rock sampling can detect location differences (upstream versus downstream); however, it is a totally river stage-dependent technique whereas circular basket implants have the advantage of being retrieved regardless of river stage. The push sled is an effective technique for sampling shallow-water sandbar habitats; both diel and seasonal differences in macroinvertebrate drift can be detected. While the data collected using the revetment implants were not analyzed because all of the samplers were covered with sand and contained only a few organisms, this technique does show promise as it can serve two functions: sampling the revetment material, while at the same time sampling the substrate that is covered by the revetment. The articulated concrete mattress slabs and blocks and the modified Hess sampler were all effective in sampling the revetment structures. Removal of entire ACM slabs is very labor intensive, whereas sampling with the ACM blocks and the Hess sampler can be accomplished with relative ease.

Of particular concern are elevated concentrations of sulfide and reduced metals, such as iron and manganese. Field investigations at Narrows Dam (Lake Greeson), located on the Little Missouri River in southwest Arkansas, document temporal and spatial patterns in the distribution of sulfide and reduced metals within and below a hydropower reservoir. Laboratory experiments involving reaeration of anoxic hypolimnetic waters were conducted to evaluate factors influencing the oxidation of various reduced metals. These results are compared with field observations. (Author 's abstract) JF - Available from the National Technical Information Service, Springfield VA. 22161.

The numerical model was calibrated to simulate measured degradation and aggradation that occurred during a major flood event in 1982. With the existing channel geometry, scour preceding the 50-year or greater flood will be insufficient to allow the flood peak to pass through the project without hitting low chords at existing bridges. The 50-year flood profile exceeded the average low-chord elevation at Riverside Avenue and Laurel Street. The 100-year and SPF profiles also exceeded the average low-chord elevation at Soquel Avenue. Calculated water-surface elevations for the 100-year flood and the SPF were greater than top-of-levee elevations at some locations. Even if the channel is dredged to its design invert, the SPF will not match the design water-surface profile due to bed scour and aggradation preceding the peak, and will hit low chords at Riverside Avenue and Laurel Street. The flood could still be contained within channel freeboard depending on the backwater effect of the two bridge decks. With the channel annually being maintained at design invert grade, the average annual dredging would be about 62,000 cu yd. Deposition quantities will vary significantly depending on the annual hydrograph and the sediment inflow concentration. If the existing channel were allowed to continue to aggrade, and a series of annual flow-duration floods occurred , the average annual deposition would reach a ' stead-state rate of approximately 1,200 cu yd in about 10 years. During these first 10 years, the deposition rate would be higher and a total of about 65,000 cu yd would be deposited. These rates would vary significantly depending on the annual hydrograph and sediment inflow concentration. It can be concluded that any proposed design would require some dredging for channel maintenance. (Lantz-PTT) JF - Available from the National Technical Information Service, Springfield VA. 22161.

However, understanding of the nature and behavior of PCBs as environmental contaminants has progressed rapidly within the scientific community with advances in analytical technology. Evaluations of PCBs in environmental samples by quantitation as Aroclors or as total PCBs are of limited value because of degradation and differential affinities of congeners for various environmental compartments. PCBs that entered the environment as identifiable Aroclor mixtures are altered by these physical, chemical, and biological processes and cannot properly be identified by comparison with Aroclor analytical standards. Comparisons of PCB-contaminated Hudson River sediments, along with water and organism tissue samples exposed to those sediments, with Aroclor standards demonstrate the frequent lack of correspondence in PCB components between Aroclors and environmental samples. Evaluation of PCBs in environmental samples can be accomplished by quantitation as totals in the isomer groups di- through decachlorobiphenyl (two to ten chlorines per molecule). This has the advantage of indicating the relative concentrations of the groups potentially containing the most toxic and bioaccumulating congeners. Recent advances in analytical techniques are making the analysis of individual congeners more feasible. Attention can be focused specifically on the PCB components that are important on the basis of toxicity, persistence, and prevalence, allowing a more accurate assessment of the environmental effects of various dredged material disposal options than is available.

AN - 36396294; 776 AB - PURPOSE: Flood control measures are proposed for Papillion Creek and its tributaries in the Omaha metropolitan area of Douglas and Washington counties, Nebraska. This final supplement to the final environmental impact statement of November 1971 concerning the proposed construction of 21 dams and reservoirs in the Papillion Creek drainage system addresses the selected comprehensive flood control plan. The locally preferred and recommended plan is a combination of structural and nonstructural measures directed mainly toward reducing the basinwide flood damage potential, although some recreational measures have been included. The major structural measures consist of modifying the Union Pacific Railroad (UPRR) bridge and improving the channel on the Big Papillion Creek between West Center Road and L Street to carry the 50-year flood event. A recreation trail for biking and jogging would be constructed within the channel improvement rights-of-way. The rights-of-way would be revegetated to minimize adverse impacts to urban wildlife and also to blend the channel improvement into the surrounding environment. The nonstructural measures consist of channel maintenance, bridge replacement, land management, floodplain management, relocation of buildings, floodproofing of buildings, acquisition and recreational development of floodplain lands from Fort Street to Dodge Street, and a flood emergency plan including an electronic flood warning system. The 50-year channel on the Big Papillion Creek, the UPRR bridge improvement, the recreation trail, and the basinwide flood warning system are the only measures of the selected plan for which there is a well-defined federal interest. The project will cost approximately $5.8 million; the benefit cost ratio is 1.4. POSITIVE IMPACTS: Implementation of flood control measures would permit easing of land use zoning restrictions on up to 630 acres of the current floodway, freeing these lands for future community growth. Property values would increase. Public facilities and services and local businesses would benefit from reduced flood damage. Construction activities stimulate the local labor force. The recommended plan would reduce the average annual equivalent of the damage potential along the Big Papillion Creek by $529,200 annually. NEGATIVE IMPACTS: The proposed plan would remove land from the tax rolls, decreasing tax revenues for Douglas and Washington counties. Increased recreational opportunities generated by the project would increase the need for police, fire, rescue, and medical services. Residual flood-related costs include flood damage to existing and future development, flood insurance administration costs, and site development costs in the Big Papillion Creek floodplain.

Preparation date: March 31, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LIGHTHOUSE MARINA, BRODERICK, YOLO COUNTY, CALIFORNIA. AN - 36398386; 727 AB - PURPOSE: Construction and operation of the Lighthouse Marina in Broderick, Yolo County, California are proposed. The proposed project site is located on the west bank of the Sacramento River, adjacent to the confluence of the American and Sacramento rivers. The 279.5 acre proposed project site currently contains the 82-acre Riverbend Golf Course and Country Club, 76 low-income apartments, 3 small marinas with boat repair facilities, 2 marina-related restaurants, a water treatment plant, and 188.3 acres of undeveloped land including a riparian woods area. A 20- to 25-foot-high levee extends through the site, generally parallel to the river along the east and north edges. The proposed mixed-use project would utilize the entire site; completion is expected to be over a 7- to 11-year period. A total of 85.4 acres would be used for residential purposes, with single-family detached dwellings; two- to three-story townhouses; a section of sale or rental units, portions of which would provide opportunities for low- and moderate-income families; and three mid-rise apartment and condominium structures of 8 to 10 stories. A five-star destination hotel and convention center complex is proposed for an 8.1 acre site adjacent to the proposed marina. Approximately 180,000 square feet of hotel-related commercial space, including shops and restaurants, is proposed along with parking for 1,000 vehicles. A professional office complex is proposed for an 8.0 acre site adjacent to the golf course. A retail commercial center of 200,000 square feet is proposed for a 9.2-acre site adjacent to the existing residential neighborhood and senior citizen complexes at the entrance to the project area. A 14,000 square foot service commercial area is proposed on a 1.5-acre site at the southern end of the marina. A 3.9-acre complex housing a yacht club, the Harbor Master's facilities, and a sheriff's substation is also proposed. The marina would occupy 25.9 acres and provide opportunities for 800 secured-access boat slips, available to residents and the public, accommodating boats up to 60 feet in length. The existing golf course would be modified to accommodate the proposed residential and office uses that would occupy areas in and around the course itself. A combination of open space areas totaling 27.9 acres is proposed throughout the development. Recreation amenities, both in-structure and within each separate area of the project, are proposed to complement the scheduled development at each location. POSITIVE IMPACTS: Additional recreational facilities would be provided for the East Yolo community as well as for low-income residents. The proposed project would be a positive step toward solving the crime and transient problems long associated with the site. Illegal trash dumping would be reduced. Replacing the existing underdeveloped uses in the area with high-quality activity could conceivably achieve the goals established by the county regarding an improvement in the quality of life reflected in the area. Another benefit that could be realized as a result of the proposed action is that increased opportunities for local employment could occur in the form of job training. NEGATIVE IMPACTS: Unavoidable adverse impacts of the proposed project on the site hydrology and water quality include the following: (1) alteration of existing drainage courses; (2) an unquantifiable decrease in groundwater recharge over the study area; and (3) long-term water quality impacts as a result of runoff from urbanized surfaces to the Sacramento River. There would be an unavoidable increase in the emissions of carbon monoxide, hydrocarbons, and nitrogen oxides, primarily associated with mobile sources. Unavoidable adverse impacts on botanical resources include: (1) loss of established vegetation and associated wildlife habitat; (2) introduction of ornamental plants; and (3) short-term loss of confirmed riparian woodland areas that provide habitat for several threatened and/or endangered species. Adverse impacts on wildlife resources include loss or displacement of wildlife, including threatened and endangered species. Adverse impacts on historic resources include disturbance of an identified historic site and possibly others. Land use would be converted to highly urbanized uses. All views and vistas of the proposed project area from adjacent residential areas, access roads, and lands across the Sacramento River would be altered from that of open space to that of a mixed-use development.

Preparation date: March 27, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LOWER OHIO RIVER NAVIGATION STUDY (MOUTH TO CUMBERLAND RIVER), ILLINOIS--KENTUCKY. AN - 36396058; 731 AB - PURPOSE: Improvement of navigation facilities on the lower Ohio River between river mile (RM) 920.5, the mouth of the Cumberland River, and RM 981.5, the Mississippi River, in Illinois and Kentucky is proposed. Navigation on this section of the Ohio River is presently being maintained by Lock and Dam Nos. 52 and 53 at RM 938.9 and RM 962.6, respectively. The preferred alternative would consist of a single replacement structure located approximately 1.8 miles downstream from Lock and Dam No. 53 near the community of Olmstead, Illinois. The project would consist of two 110- by 1,200-foot locks and a dam composed of five 100-foot-wide tainter gates, an 1,120-foot navigable pass provided by drum gates, and 880 feet of fixed weir. The drum gates would be automatically operated by remote control, with hydrostatic pressure being used to raise the gates. The 1,120-foot navigable pass would allow tows to pass over the dam and would not require any lockage for approximately 58 percent of the time. Construction costs are estimated at $550 million. Annual costs are estimated at $68.4 million, and net annual benefits are estimated at $1.7 billion, yielding a benefit/cost ratio of 25. POSITIVE IMPACTS: The preferred alternative would reduce lock congestion and transportation costs and would provide a modernized facility for safe and dependable navigation through the study area. Construction activities would relieve unemployment in the area. NEGATIVE IMPACTS: The project would require approximately 60 acres of wooded wildlife habitat and would inundate 188 acres of herbaceous cover. Another 108 acres would be inundated occasionally. Ten acres would be required for a dredged material disposal area. Construction would occur near a mussel bed that contains endangered species. One prehistoric and one historic site would be affected. One commercial fleeting area would be removed, and a public boat ramp would be relocated.

Preparation date: March 27, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - SURFACE ACTION GROUP HOMEPORTING, STAPLETON-FORT WADSWORTH COMPLEX, STATEN ISLAND, NEW YORK (FINAL SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF FEBRUARY 1985). AN - 36401697; 736 AB - PURPOSE: Location of a Surface Action Group Homeport on Staten Island, New York is proposed. The analysis contained in this supplement addresses the environmental, social, and economic impacts of certain potential changes in the facilities at Stapleton and Fort Wadsworth, and the impacts of constructing approximately 1,820 units of family housing at a number of sites in Brooklyn and Staten Island. This supplement to the final environmental impact statement describes proposed modifications to the facilities at Stapleton and Fort Wadsworth. At Stapleton these include: (1) land acquisition west from Front Street to the Staten Island Rapid Transit (SIRT) and changes in northern and southern site boundaries, resulting in a site of 40 upland acres; (2) relocation of front street adjacent to the SIRT rights-of-way; (3) changes in pier location and berthing arrangements, including deferment of the second pier and berthing of fast frigates along the bulkhead wall; (4) deletion of a portion of fill, resulting in the placement of a total of 3.6 acres of fill inboard of the Bulkhead Line; (5) construction of 1,500 feet of new sheetpile bulkhead adjacent to the pier; (6) deferment of the remaining 2,700 feet of sheetpile bulkhead from the total site waterfront length of 4,200 feet, and the interim placement of stone slope protection; (7) minor changes in the dredging plan; (8) deletion of the artificial reef; (9) deferment or deletion of the parking structure; (10) increased steam plant capacity; and (11) changes in the layout of onshore facilities and increased building space totaling 341,000 gross square feet. At Fort Wadsworth modifications include: (1) changes in facilities and land use, yielding building space of 552,000 gross square feet; (2) transfer of 30 acres of land to Gateway National Recreation Area; and (3) demolition of up to five historic batteries and the Command Post. The preferred alternative to achieve 1,820 new units of military family housing for Homeport personnel would be accomplished by constructing approximately 550 new family housing units at Fort Wadsworth, approximately 1,150 new family housing units at the South Beach housing site, and approximately 200 housing units under 801 funding on a developer-owned, as yet unidentified site, depending on developer-initiated proposals. POSITIVE IMPACTS: National policy calling for expansion of the country's naval forces to 600 ships would be implemented by providing the Navy with additional facilities near areas of industrial-maritime concentration. Commercial redevelopment would occur in the older, decaying waterfront community, and the historic building at Fort Wadsworth would be rehabilitated. Construction activities would generate 6,200 jobs. NEGATIVE IMPACTS: Concentrations of military families within any particular community would place added burdens on schools, fire and police services, housing, recreation, and other services not balanced by increased tax revenues. Significant peakhour traffic would stress local thoroughfares and increase air and noise pollution. The facility would use 860 billion British thermal units per year of oil, gas, and electric power. Approximately 3.6 acres of aquatic habitat would be replaced by 8 acres of under-pier and 47 acres of inter-pier habitat.

Preparation date: March 21, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - WILDCAT AND SAN PABLO CREEKS, CONTRA COSTA COUNTY, CALIFORNIA (FINAL SUPPLEMENT II TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF JUNE 1976). AN - 36398736; 730 AB - PURPOSE: Channel improvements are proposed for Wildcat and San Pablo creeks to provide flood protection for the cities of San Pablo and Richmond, Contra Costa County, California. The total project consists of approximately 18,000 feet of channel and flow-control improvements on Wildcat Creek and 12,400 feet on San Pablo Creek. In this final supplement II to the final environmental impact statement of June 1976, modifications to be added to the preferred alternative to provide environmental enhancement are described. Any costs in excess of the lowest cost plan selected as a result of incorporating these features would be borne 100 percent by the local sponsor, the Contra Costa County Flood Control and Water Conservation District. The added environmental features would include provision of mitigation and enhancement plantings of riparian vegetation on-site within the stream corridor; on Wildcat Creek Marsh Alignment 2, the flood overflow portion of the channel into the marsh remnant would be widened. Marsh Alignment 2 is now preferred. The transition zone on Wildcat Creek should be graded to act as a sediment trap as well as a marsh enhancement area. On both Wildcat and San Pablo creeks, the downstream earth channel would be modified so that the low flow channel is contained within a wider terraced floodplain; the service road would be lowered to increase the creek cross-section during high flows; and, where possible, the levees on both sides of the creek would be replaced with floodwalls. On Wildcat Creek, at approximately station 11+000, the flow line slopes would be modified to clear the existing sewer line. Vegetation will be placed on the south bank from the rights-of-way line to the top of the low flow channel. The concrete box culvert in the vicinity of Verde School and the open concrete channel on Wildcat Creek will be replaced by a gabion-lined channel. The feasibility of saving trees on the north bank of Wildcat Creek at Verde School and the installation of gabions between the two sets of railroad tracks on San Pablo Creek, which would act as a transition zone, would be investigated. The south bank of San Pablo Creek from Garden Tract Road westerly would be preserved "as-is" in order to avoid disturbing monitoring equipment placed in this location by the EPA and to preserve the existing riparian growth in this reach. POSITIVE IMPACTS: The alternative channel modifications would be responsive to differing conditions in each area of the project and would provide local citizens with protection from flooding while minimizing adverse environmental impacts. NEGATIVE IMPACTS: Improvements to Wildcat Creek would eliminate 15.4 acres of riparian habitat. Removal of the streamside tree canopy would reduce the amount of detritus and small organisms that serve as food for fish. Improvements to San Pablo Creek would eliminate 10.2 acres of riparian habitat. Loss of 2.5 acres of salt marsh habitat would affect several species of endangered plants and animals.

AN - 36397624; 735 AB - PURPOSE: A flood control project on the Saw Mill River in the village of Elmsford and town of Greenburgh, Westchester County, New York is proposed. The preferred alternative would be the 20-foot wide Elmsford channel modification plan. The downstream limit of the channel improvement is at station -35 + 47. Two bridges located below this station will be removed. Above station -35 + 47, the Saw Mill River flows underneath the New York State Thruway, the Saw Mill River Parkway, and two Conrail Railroad bridges that would also be removed. In addition to the removal of the bridges, the plan provides for the construction of a 10-foot wide diversion channel, south of the Saw Mill River Parkway. The channel would be approximately 1,788 feet in length with 1 on 3 side slopes. The main channel of the Saw Mill River, on the north side of the Saw Mill River Parkway, would be 20 feet wide, with 1 on 3 side slopes. From station -4 + 00, where the diversion channel joins with the main channel of the Saw Mill River, to station +13 + 20, the Saw Mill River would have a 20-foot channel with 1 on 3 side slopes. The objective of this post-authorization report is to bridge the gap between the time when the survey report was completed and the detailed engineering and design are initiated. The study was undertaken to identify, assess, and evaluate any changes in the study area since the feasibility study was completed. The project area has been changed by the inclusion of the village of Elmsford from the southernmost Elmsford-Greenburgh boundary upstream to the Cross Westchester Expressway and areas upstream and downstream of the authorized project location within the town of Greenburgh. The project has an estimated total first cost of $5.6 million. The total annual cost is $499,600. The Elmsford project would induce damages downstream, and the total damages due to the downstream effects are estimated at $100,700. The average annual equivalent benefits are estimated at $760,100, with a benefit/cost ratio of 1.27 to 1. POSITIVE IMPACTS: Economic, social, and environmental losses from flooding would be reduced and the river and its existing fish and wildlife habitats would be preserved. The integrity of the local economy would be maintained, and recreational and aesthetic features of the region would be enhanced. NEGATIVE IMPACTS: Project construction would eliminate or disturb terrestrial and aquatic resources, including a two-acre wetland area south of station 0 + 00.

AN - 36379320; 738 AB - PURPOSE: Establishment of a 15.6-acre small boat harbor is proposed at Geneva-on-the-Lake, a land area within the 725-acre Geneva State Park that lies on the south shore of Lake Erie in Ashtabula County, approximately 17 miles east of Fairport Harbor, Ohio. This final supplement to the final environmental impact statement of August 1981 presents construction revisions that will be required after geophysical surveys indicated that top-of-rock elevations were higher than previously estimated. Plan revisions would involve redesigning the harbor layout and utilizing a concrete inverted T-wall design for construction of the inner seawall, rather than the diaphragm cell wall originally proposed; lengthening both breakwater head sections; and increasing the crest elevation, based on the results of model studies performed at the Corps Waterways Experiment Station. The west breakwater would be 800 feet long, while the east breakwater would be approximately 550 feet long. Crest elevations of both breakwaters would be 8.0 feet above LWD. Berms, composed of stone revetment tying the shoreward ends of the breakwaters to higher ground, would be constructed at an elevation of 12.0 feet above LWD to prevent waves from flanking the breakwaters. Due to the close proximity of bedrock to surface elevations, excavation of lake sand would be required under the area for the proposed breakwaters to facilitate their construction directly on a rock foundation. The entrance channel design depth would be deepened to nine feet below LWD. The impervious dike, wetland water control structure, and wetland construction at Pond A would be implemented, but the dike configuration would be modified to conform to the redesigned harbor. The proposed dike plantings and littoral zone nourishment also would be included. Excess excavated material would be placed in an undeveloped camping area to the west of Wheeler Creek Road rather than to the east of this road, as originally planned. The launching ramps, mooring area, public wharf, service dock, and boat house additions still would be included. Two new wetlands, totaling 8.6 acres, would be constructed in the southeastern corner of the park. POSITIVE IMPACTS: The revised plan would provide essentially the same benefits to recreational fishing and boating as did the original plan, but with reduced rock excavation and project costs. The overall savings are estimated at $2.1 million. NEGATIVE IMPACTS: Construction of the harbor would destroy 3.3 acres of shrub, tree, and old field habitat; 2.3 acres of forest; 4.7 acres of mowed grassland; and 4.2 acres of wetlands. The project also would enclose 800 feet of shoreline by breakwaters, eliminate most or all wood duck roosting, and limit waterfowl use on major portions of the most ecologically valuable areas of the remaining wetlands.

Preparation date: March 19, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NAVIGATION DEVELOPMENT, BONNEVILLE LOCK AND DAM, OREGON AND WASHINGTON (FINAL SUPPLEMENT I TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 1981). AN - 36392982; 740 AB - PURPOSE: Construction and operation of a new navigation lock at Bonneville Dam on the Columbia River, south of the existing lock and powerhouse on the Oregon shore, are proposed. The horizontal dimensions (86 feet by 675 feet) of the new lock chamber would match those of the seven other locks on the Columbia-Snake River Navigation System. The new lock would have a depth of at least 15 feet over the lower lock sill. Both upstream and downstream approach channels with sloped walls would be constructed. Lock water would be discharged into the downstream approach channel. Submerged groins and spur dikes would be constructed upstream of the new lock, and portions of Bradford Island and Eagle Point would be excavated. A power substation would be relocated on project grounds, and six sites would be made available for disposal of 4.7 million cubic yards of material excavated during construction. The six potential disposal sites are Ross Island, the Port of Portland, the gravel pit at Cascade Locks, the Franz and Arthur Lakes area, the Port of Hood River, and the Port of The Dalles. The estimated construction cost of the new lock and approach channel is $113.2 million, with a benefit-cost ratio of 1.6; operation would cost an estimated $228,000 per year. POSITIVE IMPACTS: Operation of the proposed lock would result in faster, more efficient movement of tows and barges through Bonneville Lock. The improved lock alignment would increased safety for watercraft approaching the lock. The annual tonnage capacity of the inland waterway system would increase from 12.9 million tons to more than 30.0 million tons. NEGATIVE IMPACTS: Adverse environmental effects during the construction period would include removal of a large portion of the northern Bonny Rock Pinnacle; commitment of specific nearby natural resources (stone fill material, sand, and gravel) to construction purposes; loss of a portion of the Bonneville Park grounds; loss of the natural stand of Douglas fir on Bonny Rock, along with natural vegetation on Ives and Pierce islands; and wind and water erosion or burning associated with vegetation disposal. The action would involve the relocation of one building and 0.25 mile of the Union Pacific Railroad's main line and siding. The project also would remove wildlife habitat on the Bonneville site. Deposition of soil and organic materials could increase biochemical oxygen demand and concentration of coliform bacteria in the Columbia River. The operation of heavy construction equipment would degrade air quality, and construction activities temporarily would remove a portion of the riverbank from use for recreational fishing. The influx of construction workers would strain housing supplies in surrounding communities. Adverse impacts associated with the operational period would include increased noise due to the increase in river traffic; detrimental effects on aquatic, emergent, and riparian plant life because of possible increased wave action and potential foreign substance spills; degradation in air quality, especially in port areas from expansion of barge traffic; and a possible decrease in the growth rate of rail transportation.

AN - 36397582; 723 AB - PURPOSE: The Illinois State Toll Highway Authority has applied to the Army Corps of Engineers for a permit, pursuant to Section 404 of the Federal Water Pollution Control Act of 1972, in connection with the proposed North-South Tollway in DuPage and Will counties, Illinois. The permit is required for the discharge of fill material into Lily Cache Creek, tributaries to the East Branch of the DuPage River, and wetlands along the tollway corridor. Four alternatives are being considered: (1) deny the permit, (2) issue a Section 404 permit for the construction of the North-South Tollway with mitigation for significant environmental impacts, (3) upgrade existing Illinois Route 53 to a four-lane highway without the North-South Tollway, and (4) upgrade existing Illinois Route 53 to a four-lane highway with the North-South Tollway. The North-South Tollway alternative consists of constructing 17.4 miles of tollway with mitigation measures. The Route 53 upgrades would include roadway widenings, turning lane additions, and general upgrading of existing drainage facilities. POSITIVE IMPACTS: The primary benefit of the tollway would be reduction of congestion on arterial roads, primarily through the diversion of trucks and through traffic from arterial routes. Travel times for persons commuting between locations in the northern and southern parts of the county would be substantially reduced. Reduced congestion on arterial roads would produce a safety advantage and allow quicker responses from police, fire, and ambulance services. The tollway would create industrial and commercial growth along its corridor. NEGATIVE IMPACTS: Construction of the tollway would displace 120 residences, 12 businesses, and 1 church, and would divide several residential neighborhoods. The aesthetic character of open space in the rights-of-way would be replaced by the highway and its supporting structures. Tollway traffic would slightly increase carbon monoxide, salt dispersion, and noise levels in adjacent areas. Approximately 13 miles of noise barriers would be installed to reduce noise levels in residential areas. The tollway directly affects 74.1 acres of wetlands, which would be mitigated by the creation/enhancement of 113.4 acres of wetlands at four locations. There would also be a loss of 238.2 acres of old field and 140.0 acres of forested habitats. Approximately 4.6 acres of the Churchill Prairie would be directly lost. Construction activities related to the Route 53 upgrade would cause temporary inconveniences to motorists and residents. Changes in traffic flow volumes would also slightly increase noise levels in the surrounding areas.

AN - 36392723; 728 AB - PURPOSE: Construction of the 642-acre West Beach resort complex, which includes housing, boating, and recreational features, in Honouliuli of the Ewa District on the island of Oahu, Hawaii is proposed. This final supplement to the final environmental impact statement of September 1980 has been refocused to define and address those actions that fall within the scope of Corps of Engineers permit authority, namely construction of the marina and the bathing beach lagoons. If the project is fully realized as planned, the development would include 4,000 hotel-condominium units on 86.3 acres, 5,200 residential units on 186.2 acres, 17.8 acres of commercial development, a 33.9-acre marina with 500 berths and supporting facilities, an elementary school on 6.9 acres, a 171.3-acre golf course, a 1.9-acre beach club, 46.8 acres of parks, a 21.8-acre cultural center, a 13.1-acre lagoon system, four bathing beach lagoons, and 47.9 acres for a circulation system and transit stations. Power would be transmitted to the development via two 46-kilovolt transmission lines. Estimated cost of the project in 1980 dollars is $1.1 billion. POSITIVE IMPACTS: The project would provide living accommodations, recreational benefits, and employment for numerous persons. Development features would include creation of 47 acres of aquatic habitat. NEGATIVE IMPACTS: Approximately 75 acres of terrestrial wildlife habitat would be inundated, and 266 acres of prime farmland and 133 acres of other important agricultural lands would be converted to urban uses. The development would require 4.5 million gallons per day (MGD) of water and would generate 2.5 MGD of sewage effluent. Dredging along the shoreline and within the entrance channel would destroy coral resources in limited areas. All residents would be exposed to aircraft noise, and some residents living in the vicinity of Farrington Highway would be exposed to highway noise levels in excess of Department of Housing and Urban Development standards. Marina and lagoon development would influence local water quality along the coast, and infiltration would introduce brackish water and nutrient-laden water into the aquifer, possibly violating federal water quality standards. Archaeological sites would be disturbed and destroyed, and a colony of rare plants would be destroyed by marina and golf course development.

The widening alternative consists of reconstructing existing Route 82 from Route 11 to Route 85 at Salem Four Corners and Route 85 from Salem Four Corners south to I-395 in Waterford, completing the Frontage Road system along I-95 in Waterford and New London, and reconstructing I-95 from west of Route 85 in Waterford to approximately the Waterford/New London town line. The I-95/Route 85 interchange would be revised. The expressway relocation alternatives considered in this statement consist of two alignments. Alternative C would extend Route 11 from Route 82 in Salem to I-95 in Waterford to a point west of the Route 85/I-95 interchange. Improvements to I-95 and the Frontage Road System would take place from that point east to approximately the Waterford/New London town line. Alternative D would extend on an alignment west of Alternative C from Route 82 in Salem to the I-95 /I-395 interchange in Waterford. Improvements to I-95 and the Frontage Road System would be made from that point east to approximately the Waterford/New London town line. The widening alternative would be approximately 10.3 miles long and would have an estimated construction, preliminary engineering, and contingency cost of $55 million. Alternative C is approximately 10.7 miles long, with a cost for the same items of $176.7 million. Alternative D is approximately 10.2 miles long, with a cost for the same items of $123.5 million. POSITIVE IMPACTS: The widening alternative would provide additional capacity on Routes 82 and 85 but would continue to rely on a system that mixes very heavy through traffic volumes with local access traffic. Alternative C would provide for diversion of through traffic from Routes 82 and 85, resulting in generally acceptable operations without widening. Alternative D provides for diversion of through traffic from Routes 82 and 85. This alternative results in the greatest improvements to I-95, providing acceptable operations into New London, and results in the lowest traffic volumes along Route 161. Alternative D would provide for excellent access to and from the region and its major population and activity centers while also providing for the greatest increase in local service benefits along all of the corridor arterials. A decrease in traffic noise levels along Route 85 would result from Alternatives C and D. NEGATIVE IMPACTS: With the widening alternative, the number of residences along Routes 82 and 85 that experience noise levels greater than 70 dBA would increase from 30 to 62. I-95 improvements associated with the widening would result in an increase in existing noise levels along I-95. With Alternatives C and D, a new noise source would be introduced into the areas north of I-95. With the integral noise abatement barriers proposed, noise level increases of 4 to 12 decibels are projected. The widening alternative would involve an estimated 36 residential property displacements and 6 commercial or other displacements. Alternative C would involve 24 residential displacements and 3 commercial or other displacements. Alternative D would involve 29 residential displacements and 2 commercial or other displacements. Some reduction of tax revenue due to property acquisition by the state would be experienced from all alternatives. The widening alternative would result in acquisition of two potentially significant historic structures and would require land from two other potentially significant historic structures. Alternative C would necessitate acquisition of land associated with two potentially significant historic structures, and Alternative D would take one potentially significant historic structure. The widening alternative would remove approximately 46 acres of wildlife habitat, Alternative C would remove approximately 481 acres, and Alternative D, 378 acres. There would be short-term impacts to area fisheries resources with construction of any alternative. All of the alternatives would remove some prime farmland and would involve some measure of floodplain encroachment.

Preparation date: March 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - HARRY S. TRUMAN DAM AND RESERVOIR, OSAGE RIVER, MISSOURI: A REPORT ON THE FUTURE DIRECTION OF HYDROPOWER (SUPPLEMENTAL INFORMATION REPORT). AN - 36403849; 686 AB - PURPOSE: Revised information is offered on the construction of a 2.6-mile levee downstream of the Harry S. Truman (HST) Dam outlet channel and across the Osage River from Warsaw, Missouri. This supplemental information report amends previous environmental impact statements and provides additional information on the operation of the HST Dam and Reservoir. The majority of the alternatives evaluated for operation of the HST power facility have been eliminated for the foreseeable future. Alternatives retained for further evaluation and consideration include operating the existing project with four, five, and six slant-axis Kaplan type reversible pump-turbines capable of pumping water back into the HST Reservoir, but without pumpback. Normal hydropower operation at the project would consist of operation with four units from two feet of hydropower storage in the design power pool without pumping. The pumping feature of the project would not be used until means become available to prevent unacceptable losses to the fish population from the use of pumping. Monitoring of the area downstream of the dam would continue as part of the project operation in order to identify any long-term cumulative or unforseen effects of the hydropower operation that might result in an unacceptable adverse impact. The Corps of Engineers would continue to work gradually toward five- and six-unit power operations, with careful evaluation of impacts as efforts progress. Conventional generation with up to six units, supplemented with spillway releases as necessary, would continue for flood control operations. Five and six-unit generation from the two feet of design power storage in the project would not be used except as a last resort to avert a power shortage that would endanger life and property. POSITIVE IMPACTS: Power production with four units would produce $12.3 million in power benefits annually. Power production with five and six units would increase power benefits by about $400,000 per unit annually over the four-unit power benefit. Going from four to five units would increase power benefits by $50,000 annually, and going from five to six units would increase power benefits by $18,000 annually. NEGATIVE IMPACTS: Elimination of pumpback and operation of the HST Dam and Reservoir with less than six units may adversely affect the power utilities and their customers, since dependable capacity and average annual energy production would be reduced. Possible effects of this decision include an increase in rates to power customers and the construction of a fossil fuel plant to offset the reduction of hydropower capacity, assuming such capacity is not available from other existing sources. In general, adverse impacts to the downstream area would be increased with five- or six-unit operation.

Preparation date: February 28, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - TUSCUMBIA RIVER WATERSHED, ALCORN AND PRENTISS COUNTIES, MISSISSIPPI AND MCNAIRY COUNTY, TENNESSEE. AN - 36401590; 685 AB - PURPOSE: The Tuscumbia River Watershed environmental impact statement (EIS) prepared by the Department of Agriculture, Soil Conservation Service (SCS) in May 1984, presents a plan for construction of a system of dams and channels in Alcorn and Prentiss counties in Mississippi and McNairy County in Tennessee to solve agricultural and urban flooding problems within the Tuscumbia River watershed. The recommended plan consists of nine floodwater retarding structures, 13.6 miles of channel work, 10.9 miles of floodways, 9.1 miles of channel clearing and snagging, and 65 miles of selective snagging. A conservation easement consisting of 2,328 wooded acres along Tuscumbia River between its junction with Tarebreeches Creek and Cypress Creek will also be included in this plan. The Army Corps of Engineers was requested by the Tuscumbia River Water Management District of Alcorn and Prentiss counties, Mississippi to provide assistance in alleviating flooding problems along the lower reaches of the Tuscumbia River. This detailed project report was prepared in response to that request. The work recommended in the Corps' report was part of the overall project recommended by the SCS. The Corps' project covers a 7.4-mile reach on the lower Tuscumbia River from just below Tarebreeches Creek to the confluence of Cypress Creek and consists of major cleanout in this area. Since the Corps' recommended plan is essentially that which is recommended by the SCS final EIS, the preparation of a revised EIS was deemed unnecessary and the SCS final EIS has been adopted in its entirety by the Corps of Engineers. POSITIVE IMPACTS: Implementation of the proposed plan would result in a reduction in flooding and flood damages, a reduction in sediment leaving the watershed, an increase in prime farmland and in riparian woodland, and would reduce the total expected annual damages to area crops by 5 percent. NEGATIVE IMPACTS: Project activities would result in the loss of Type I wetlands and a temporary loss of minimal intermittent streams.

Preparation date: February 27, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MANASQUAN RESERVOIR SYSTEM, MONMOUTH COUNTY, NEW JERSEY. AN - 36398331; 687 AB - PURPOSE: Construction of a river-skimming intake facility on the Manasquan River, in conjunction with the Oak Glen reservoir, as a means of providing an additional water supply within Monmouth and northern Ocean counties, New Jersey, is proposed. The Oak Glen reservoir would have a storage capacity of approximately four billion gallons and a surface area of approximately 760 acres. River skimming would involve placement of a water diversion structure along the Manasquan River. Water would be diverted from the river, and a pumping station located at the intake would distribute water either directly to local purveyors or to the reservoir for storage. Reservoir water would be used during periods of low flow on the Manasquan River. There would be no storage capacity at the intake. POSITIVE IMPACTS: This reservoir system would provide an estimated safe dependable yield of 30 million gallons of water per day (mgd), with an eight mgd minimum passing flow to the Manasquan River downstream of the water intake facility. The overall impact of operating a river-skimming intake facility on estuarine species in the Manasquan River is expected to be positive, due to an increase in estuarine habitat that would occur through salinity increases. NEGATIVE IMPACTS: Construction of the Oak Glen reservoir would impact 359.6 acres of palustrine forested wetlands, 10.6 acres of palustrine scrub shrub wetlands, 2.8 acres of palustrine unconsolidated bottom wetlands, 12.8 acres of agricultural and herbaceous rangeland, 66.4 acres of shrub and brush rangeland, 27.6 acres of mixed rangeland, 239.2 acres of deciduous forest, and 46.7 acres of mixed forest. These acres provide habitat of high to medium value for wildlife species. In addition, approximately 3.8 miles of Timber Swamp Brook and its tributaries would be impacted. All of these areas would be lost through construction of a dam and necessary dikes and flooding for reservoir creation. Construction of a river-skimming intake facility on the Manasquan River would impact 19.7 acres of agricultural land, 0.2 acres of mixed rangeland, 1.1 acres of palustrine forested wetlands, and 0.2 acres of palustrine scrub shrub wetlands. These areas would be developed for the intake structure, sedimentation pool, and water-treatment plant. Diversion of water from the Manasquan River would impact river habitat downstream of the intake. Conversion of most, if not all, of the existing freshwater tidal portion of the Manasquan River to brackish water habitat would result. Between Orchid Path and Allenwood Road, cattail and common reed would expand into areas currently dominated by mixed aquatic emergent vegetation such as wild rice, water-hemp, water-smartweed, arrow-leaved tearthumb, and impatiens. Reduced river flow downstream of the intake facility would degrade habitat for freshwater fishery resources. It is expected that trout would probably not survive the summer low-flow period.

Preparation date: February 27, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COUNTY STATE AID HIGHWAY 52, HENNEPIN AVENUE, N. SECOND STREET TO MAIN STREET, SOUTHEAST HENNEPIN AVENUE BRIDGE OVER THE MISSISSIPPI RIVER, MINNEAPOLIS, MINNESOTA. AN - 36403803; 670 AB - PURPOSE: Replacement of the bridge and approaches carrying County State Aid Highway (CSAH) 52 (Hennepin Avenue) over the main channel of the Mississippi River in Minneapolis, Minnesota is proposed. The bridge and its approaches would extend 2,700 feet from North Second Street to Main Street Southeast. The bridge would be approximately 950 feet long, crossing the river, adjacent park trails and roads, and the railroad flats. The improved roadway would carry three traffic lanes in each direction, separated by a median. The new six-lane roadway would have a design speed of 40 mph. The preferred alternative follows the existing alignment and is made up of the following: (1) West Segment, Railroad Flats Bridge Replacement; (2) Central Segment, River Bridge Replacement; and (3) East Segment, East Channel (Merriam Street) Bridge. The total estimated cost of the project would be $27.7 million. POSITIVE IMPACTS: The new bridge would replace the two structurally deficient structures that currently carry CSAH 52 traffic across the river, easing travel between the Minneapolis central business district and Nicollet Island. Replacement of the existing bridges with the proposed new bridge would increase the number of travel lanes crossing the river at this point from four to six. Improvement of access and expansion of capacity would provide access to areas planned for development on either side of the river. NEGATIVE IMPACTS: Development of new rights-of-way could encroach on De La Salle High School and affect access to and from the school, encroach on the floodplain of the Mississippi River, and traverse the St. Anthony Falls Historic District, damaging historic values therein, principally, the removal of the historic 1888 steel arch river bridge (Bridge 90589).

Preparation date: February 26, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED FLOOD DAMAGE REDUCTION PLAN, CAZENOVIA CREEK, WEST SENECA, ERIE COUNTY, NEW YORK. AN - 36379301; 688 AB - PURPOSE: Construction of an ice control structure on Cazenovia Creek in West Seneca, Erie County, New York is proposed. The project would include a low reinforced concrete dam, a stilling pool, and a high-flow overflow area. The dam, comprised of a multistage weir, would extend across Cazenovia Creek and the floodplain at a site approximately 2,300 feet upstream of the Mill Road Bridge. It would be approximately 900 feet long, and its low stage weir would extend approximately 250 feet from the high south bank of the creek channel, across the channel, and into the present floodplain. The dam would incorporate a four-foot high, six-foot wide gated culvert opening to permit normal flows and draining of the stilling pool for that period of the year that the ice retention function is not needed. The high-stage weir would extend from the low-stage weir the remaining distance across the creek side of the floodplain. This part of the dam would stand approximately four feet above the surface of the floodplain near the creek. Two small areas (several acres) would be excavated both upstream and downstream of the ice retention structure to accommodate increased spillway and ponding areas. A high-flow overflow channel would be constructed just north of and around the ice retention structure to accommodate extreme flow conditions. The cost of the ice retention structure would be $2 million, with a benefit/cost ratio of 1.4. POSITIVE IMPACTS: The ice retention facility would relieve the lower Cazenovia Creek basin from flooding due to ice formation and ice jams, protecting approximately 64 businesses and 697 residences. The need for ice-jam related flood emergency services along the lower reaches of Cazenovia Creek would be eliminated. Lower basin benefits would be realized in several locations in terms of reduced property damage and health and safety. A total of approximately 2.5 acres of new, temporary, benthic habitat would be created in the area of the stilling pond. NEGATIVE IMPACTS: Construction of the proposed project would result in some temporary deterioration in water quality, as well as in air quality. A total of 4,400 square feet of channel-bed material would be removed for the construction of the ice retention structure. Invertebrate organisms within the immediate construction site would experience low survivability. Resettlement of temporarily suspended silt and sediments created by construction activity could smother some benthic organisms downstream. Approximately 19 acres of existing terrestrial vegetation could be destroyed. The vegetative habitat for wildlife on disturbed soils would change from naturally established tall woody vegetation to planted lower ground herbaceous grasses and legumes. Construction of the ice retention structure would pose an impact to the existing fish population within the area. The dam would impede the upstream movement of fish and would act as a temporary impassable barrier throughout the ice retention season when the sluice gate is closed to form the stilling pond.

AN - 36395955; 683 AB - PURPOSE: Operation and maintenance of 13 locks and dams in a 9-foot channel, 242.5 miles long, in the Mississippi River from Minneapolis, Minnesota to Guttenberg, Iowa are proposed. The project consists of necessary channel dredging to maintain a 9-foot depth for navigation on the Mississippi River and 14.7 miles on the Minnesota River, 24.5 miles on the St. Croix River, and 1.4 miles on the Black River in Iowa, Minnesota, and Wisconsin. This supplement describes the general channel maintenance plan for lower pool 5 on the Upper Mississippi River, including rehabilitation of the 4,000-acre backwater lake, Weaver Bottoms. The primary objectives of the project are to develop a 40-year channel maintenance plan for lower pool 5, to reduce maintenance dredging requirements in lower pool 5, and to restore the habitat quality of the Weaver Bottoms area by modifying side channels and constructing islands with maintenance-dredged material. POSITIVE IMPACTS: Modifying the side channels would increase the efficiency of the channel, thereby enhancing recreation, commercial navigation, and hunting. The local economy would also be enhanced by the employment of local workers and the use of the local quarries. The preferred alternative would substantially reduce the existing sedimentation problems in Half Moon Lake and near the side channel openings into Weaver Bottoms. It would preserve the area for fish and wildlife. The project would reduce dredging volumes by 260,000 cubic yards of sediments every 40 years (6,500 cubic yards annually). Overall, the project is expected to have a very positive environmental benefit on the Weaver Bottoms backwater by improving abundance and diversity of aquatic vegetation; improving furbearer and waterfowl feeding, resting, and nesting habitats; and increasing recreational opportunities. NEGATIVE IMPACTS: The reduced number and modification of the remaining access points may somewhat impede fish movement into and out of the Weaver Bottoms area. Approximately 100 to 118 acres of aquatic habitat would be directly modified, of which approximately 13 to 18 acres of side channel habitat would be modified to partial rock closing structures that could become valuable areas for fish and other aquatic organisms. The remaining side channel areas would be modified to terrestrial habitat. Project construction would have short-term negative effects on land transportation, noise, and area aesthetics.

Preparation date: February 24, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED PLAN FOR FLOOD CONTROL IN SAUQUOIT CREEK, VILLAGES OF WHITESBORO, YORKVILLE, AND NEW YORK MILLS, ONEIDA COUNTY, NEW YORK. AN - 36392953; 689 AB - PURPOSE: A plan for reducing or preventing flooding along Sauquoit Creek in the village of Whitesboro, Oneida County, New York is proposed. The overall study area encompasses the lower three miles of Sauquoit Creek in the villages of Whitesboro, Yorkville, and New York Mills in the town of Whitestown. The area extends from the Route 5A bridge in New York Mills downstream to the confluence of Sauquoit Creek with the Mohawk River. The preferred alternative would provide an approximate 10-year level of flood protection to the lower reaches in the damage area. It would also provide for channelization of an approximate one-mile length of Sauquoit Creek and construction of a high-flow diversion channel, 3,200 feet long, across the floodplain below the Conrail bridge. The plan would include widening and straightening the Sauquoit Creek channel with side slopes of 1 on 2-1/2. The diversion channel would carry high flows from Sauquoit Creek just below the Conrail bridge to the Mohawk River approximately 240 feet downstream of the Sauquoit Creek confluence. The proposed bottom width for the modified Sauquoit Creek channel would be 60 feet. The diversion channel would have a 60-foot bottom width and 1 on 4 side slopes. The top width of the diversion channel would vary from 115 feet to 140 feet; the bottom elevation would descend from 404 feet above mean sea level (MSL) at its entrance to 394 feet above MSL where it empties into the Mohawk River. A weir section would separate the Sauquoit Creek channel from the diversion channel and have a height of 406 feet above MSL. The weir section would ensure that normal flows are maintained within the natural Sauquoit Creek channel. Consideration of alternatives for disposal of excavated material would depend on the nature of the material. The annual costs would range from $22,200 to $272,000, with a benefit/cost ratio ranging from 1.0 to 1.9. POSITIVE IMPACTS: The proposed project would protect development within the damage area from floodwaters up to the level of the 10-year event. This protection would be afforded to approximately 500 residences and commercial, industrial, and institutional structures upstream to the Parkway School above Route 69. NEGATIVE IMPACTS: Construction activities would cause short-term effects of erosion of soil material and organic debris into the waterway. Construction activities would also disturb sensitive terrestrial species in the project area and displace all organisms within the project rights-of-way. Project maintenance activities would have impacts similar to initial construction. Removing accumulated sediments from the project channel would disturb aquatic resources and maintenance of the banks and overflow channel, including removal of woody vegetation, and would disturb terrestrial resources. Twenty-five acres of fish and wildlife habitat would be directly impacted (13 acres of wetland, and 12 acres of upland). Up to 15 wetland acres might have secondary impacts. Some 1,450 acres of natural stream would be channelized and 19 acres of floodplains would be directly modified. Up to 15 acres of floodplains might have secondary impact. LEGAL MANDATES: Executive Orders 11988 and 11990, and Flood Control Act of 1948, as amended (33 U.S.C. 701s).

Preparation date: February 21, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED FLOOD CONTROL PROJECT FOR THE LOWER MISSION CREEK, SANTA BARBARA COUNTY STREAMS, CALIFORNIA. AN - 36392673; 679 AB - PURPOSE: A comprehensive flood control plan for the Santa Barbara County Streams and Mission Creek, Santa Barbara County, California is proposed. The plan includes the construction of debris structures in Mission and Rattlesnake canyons at the existing dam sites; construction of a debris basin at Rocky Nook Park; and channel modifications from State Street to the coastal outlet, except through Oak Park. Mitigation measures for the plan include the creation of riparian and estuarine habitat and the planting of oak and sycamore trees. The Lower Mission Creek (Carrillo Inlet) Alternative is the recommended plan; it would provide flood protection to the area downstream of Carrillo Street by constructing a concrete channel from Carrillo Street to Cabrillo Boulevard and constructing a coastal outlet. The flood control project consists of the following elements: (1) construction of a grouted stone apron between the freeway ramp and the channel at Carrillo Street; (2) construction of 100-foot-long parapet walls along each curb line of Carrillo Street, ranging in height from 2 feet to 0.5 feet; (3) concrete channelization of the existing channel from Carrillo Street to the ocean outlet; and (4) construction of a coastal outlet with grouted stone side walls. The estimated total first cost would be $9.1 million with a benefit /cost ratio of 1.2. POSITIVE IMPACTS: The plan would provide 100-year flood protection to the area downstream of Carrillo Street. Mitigation for this plan includes the creation of an acre of estuarine habitat and 1.6 acres of oak woodland habitat. NEGATIVE IMPACTS: Approximately 3.2 acres of low-quality riparian, oak-woodland habitat and 1.0 acre of estuarine soft bottom habitat would be impacted. The Twin Palms archaeological site and the Potter Hotel Foot Bridge and Southern Pacific Railroad Bridge, potentially significant historic properties, would be impacted. Open space corridor from Carrillo Street to the ocean would be lost. Construction activities at the mouth of Mission Creek would result in a permanent loss of one acre of soft substrate habitat, but would also increase the amount of hard substrate estuarine habitat. Water quality in the lower reaches of the creek, particularly the outlet, would decrease due to construction generated sediment and creation of temporary impoundments. Some species occupying habitats within the study area may be intolerant of the increased turbidity.

AN - 36388764; 673 AB - PURPOSE: Approximately 4.3 miles of roadway improvements to the Columbia South Shore area, Multnomah County, Oregon are proposed. The No Build Alternative proposes no improvements to the existing two-lane configuration of Airport Way between I-205 and N.E. 138th Avenue and none to address existing deficiencies or future traffic demand. The Build Alternative, with its two options, proposes to widen the existing section of Airport Way, to construct an extension from the present terminus at N.E. 138th Avenue to Sandy Boulevard at N.E. 181st Avenue, and to widen N.E. 181st Avenue south of Sandy Boulevard to the terminus of Oregon's I-84 interchange project. The Airport Way improvement includes a 72-foot roadway section consisting of four travel lanes, a center left-turn lane, bikeways, and 10-foot border areas on both sides for sidewalks, landscaping, and illumination. Intersections with N.E. 122nd, 138th, 148th, 158th, and Sandy/181st avenues would be fully signalized and provided with left-turn refuges. Bus turnouts to accommodate Tri-County Metropolitan Transportation District (Tri-Met) service would be provided at a number of locations along Airport Way at approximately one-half mile intervals. The total project length is 4.2 to 4.3 miles, depending on the location option selected. Construction costs are estimated to range from $15.1 million to $15.5 million, depending on the option selected. The cost estimate could increase, based on the extent of mitigation required, that is, rights-of-way compensation and wetlands replacement. POSITIVE IMPACTS: Construction of Airport Way would result in improved east-west traffic movement; would provide traffic circulation, improved access to existing businesses and industries within the study area, and associated urban services to parcels currently lacking such services; would facilitate industrial development by providing improved access to industrially zoned land; and should reduce the response time of emergency service vehicles to this area. Land values are expected to increase with the construction. Employment associated with the anticipated industrial development is estimated at 16,890 new jobs. NEGATIVE IMPACTS: Construction activities would temporarily increase carbon monoxide levels and noise levels. The Build Alternative would require 30.9 to 31.9 acres of land and would disrupt three existing business operations. There would be a direct impact to 2.0 to 4.0 acres of wetlands, and 11.7 to 12.2 acres of natural vegetation would be removed. Direct and indirect impacts would result in conversion of 559 acres of agricultural land. Some loss of habitat would occur as a direct result of roadway construction, and certain species with low tolerance for human intrusion would decline. LEGAL MANDATES: Executive Order 11990.

AN - 36384622; 680 AB - PURPOSE: Construction of the Stagecoach Reservoir Project, located in Routt County in northwest Colorado along the Yampa River in the Upper Yampa River valley, is proposed. The project would provide water for agricultural, industrial, municipal, and recreational uses; for fish and wildlife; and for hydroelectric power generation. Stagecoach Dam would be constructed of roller-compacted concrete, a method that saves on material and material-handling costs. The dam would be 145 feet high, its crest would be 450 feet long and 24 feet wide, and its volume would be 114,000 cubic yards. The reservoir would have a capacity of 33,720 acre-feet and would be 2.9 miles long. Material for the dam would be obtained from the reservoir basin. The outlet and diversion works would be designed to pass 450 cubic feet per second (cfs). Minimum releases would be the lesser of 40 cfs or the natural inflow. A multilevel outlet would regulate the releases to obtain optimum downstream temperatures for fish. An 800-kilowatt hydroelectric generating plant would be located at the foot of the dam. Recreation facilities would include a 100-unit campground, 50 picnic units, 2 marinas, a swimming area, and trails. Mitigation for wildlife losses would consist of the acquisition and dedication of approximately 1,288 acres of private land for elk, the development of 125 acres of prime waterfowl habitat, and the creation of 150 acres of wetlands that would result from project irrigation. POSITIVE IMPACTS: Recreational possibilities in the area would be greatly enhanced, and Routt County and Colorado would benefit economically, especially during the spring, summer, and fall. Potential for flooding would be reduced, because flows in the streams would be controlled. The recommended plan would result in considerable enhancement of the fishery below Stagecoach Dam because of clearer water, increased minimum flows, improved water temperatures, cleaning of the cobble substrate, decreased streambank erosion and sediment deposition, and reduced maximum flows. The recommended plan would result in a net gain of approximately 450 acres of agricultural land. Recreational use in the project area would increase by approximately 73,000 recreation-days annually. The project would create some 200 jobs. The anticipated recreational use should help to balance the economy of the county and the local communities. NEGATIVE IMPACTS: Both permanent and temporary losses of vegetation would occur, primarily to agricultural and mountain brush communities. Permanent losses of vegetation, mostly from reservoir inundation, would total approximately 753 acres. Approximately 120 acres of willow and 160 acres of riparian habitats would be lost. Revegetation of native grasses, brush, and riparian communities would require some 25 years to return to conditions visually comparable to those existing. Approximately 170 critical winter habitat units for elk and 93 willow habitat units would be lost. Some minor big game migration routes would also be lost. The loss of wetlands and riparian willow thickets would create a loss of breeding habitat for nongame shorebirds and songbirds and many small nongame mammals, furbearers, and amphibians. Local traffic would increase.

AN - 36384763; 682 AB - PURPOSE: Maintenance dredging and construction of a confined disposal facility for backlog and maintenance dredged material from the federal deep-draft navigation channel in Indiana Harbor and Canal in Lake County, Indiana are proposed. The proposed plan provides for dredging shoaling sediments in the Indiana Harbor and Canal, as well as constructing, operating, and maintaining a confined disposal facility in Lake Michigan, east of Jeorse Park in East Chicago, for the disposal of sediments classified as moderately and heavily polluted. The proposed facility would not be acceptable for the disposal of sediments classified as toxic. Indiana Harbor and Canal sediments classified as toxic would not be part of the proposed project, but would be addressed when acceptable disposal alternatives are developed. POSITIVE IMPACTS: The project would preserve the navigational use of Indiana Harbor and Canal, preserve the potential for future industrial and commercial development, and benefit the local economy. The project would also provide for the removal and confinement of polluted sediments, which would limit existing resuspension of contaminants and potential exposure to aquatic organisms. The maintenance of the navigation channel to authorized depths would promote the settling of contaminated sediments discharged into the waterway and reduce substantially the net yield of contaminated sediments to Lake Michigan. NEGATIVE IMPACTS: The proposed plan would temporarily impact water quality, dislocate fish, and reduce benthic invertebrate populations during dredging activities. Confined disposal facility construction activities would also create short-term changes in water quality and dislocate fish from the construction site.

AN - 36400099; 690 AB - PURPOSE: Widening and deepening of the federal navigation channels in Kill Van Kull and Newark Bay, New Jersey and New York are proposed. Deepening from 35 to 44 feet mean low water (mlw) in sediment and 46 mlw in rock would start at the entrance to Kill Van Kull and proceed north along Newark Bay to 0.8 mile south of the New Jersey Turnpike bridge and would include Port Elizabeth and Port Newark channels and associated pierhead channels. Channels would be widened at selected sites to permit safer turns and to eliminate sharp bends. Pipeline and utility cables on or under the existing bottom would be lowered or removed, and berthing and local access areas at port facilities would be dredged to commensurate channel depths. Approximately 27 million cubic yards of dredged materials would be disposed of at the mud dump in the New York Bight. The results of a detailed study to evaluate disposal methods indicate the New York Bight to be the only viable option. This supplemental draft environmental impact statement indicates that detailed fishery and benthic sampling occurred during 1984 and 1985. The results show that the area is an equivalent habitat to surrounding portions of the Hudson estuary regarding fish populations. The benthic community appears more restricted, and the project area also appears very homogeneous with regard to shallow and deeper areas. This supplement also provides additional information on sediment quality and details related hydraulic impacts. Estimated cost of the project is $166.3 million, and the benefit-cost ratio is estimated at 9.0. POSITIVE IMPACTS: Improvements in navigation and reduction in marine traffic would reduce loss of life, oil spills, and costs associated with marine accidents. Increased navigational safety and the reduced likelihood of oil spills also would benefit recreational resources. Deeper channels would permit ships to arrive at the docks fully loaded, which would reduce transportation costs and help to maintain the commercial viability of the port. Maintenance of the oceanborne commerce also would be beneficial to local rail service and the interstate highway system. Removal of polluted bottom material would be a long-term direct benefit to the project area. NEGATIVE IMPACTS: Enlarging the channel would result in a moderate decrease in the flushing capability of the bay, an increase in the rate of shoaling, and an upstream shift in the location of major shoaling areas. Maximum and average current velocities probably would be reduced by the channel enlargements. If the changes result in a significant upstream predominance of bottom flow, sediments would be carried into and trapped in the enlarged channels. Some shallow water areas would be lost, and deepening could result in a change in the benthic inhabitants. Bottom vegetation would decline because of decreased light penetration. Disposal of dredged material would further degrade the ecosystem in the New York Bight.

Preparation date: February 7, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MARYLAND ROUTE 36 FROM 0.5 MILE SOUTH OF SELDOM SEEN ROAD TO RUSKIRK HOLLOW ROAD, ALLEGANY COUNTY, MARYLAND. AN - 36385944; 669 AB - PURPOSE: Construction of a two-lane highway on new location bypassing the town of Lonaconing from 0.5 mile south of Seldom Seen Road to Buskirk Hollow Road in Allegany County, Maryland is proposed. This is the last segment of Maryland Route 36 between Westernport and Frostburg that has not been improved. Four Build Alternatives in addition to the No Build Alternative are considered. The Build Alternatives propose to relocate Maryland Route 36 away from the center of Lonaconing. The proposed typical section consists of a two-lane, 24-foot roadway with 10-foot shoulders and 16 feet of safety grading. The 10-foot shoulders would be widened to 12 feet to serve as climbing lanes where needed. All Build Alternatives were developed using minimum 50 mph design speed criteria or better. Access to any of the bypass alternatives is proposed only at those locations where existing or relocated roads would be crossed at-grade. In all cases, access would be provided at existing Maryland Route 36 at each end of the project and at Buskirk Hollow Road. Alternates 1 and 5 bypass Lonaconing to the east. Alternates 2 and 2A bypass Lonaconing to the west. Each pair of alternates shares a common point at which each is divided into two segments. The segments of each pair of alternates can be recombined to form two additional alternates. The No Build Alternative would provide no improvements to the existing two-lane highway. Normal maintenance would continue for both the roadway and bridges. The existing roadway width varies from 20 to 30 feet and there are no turning lanes. The No Build Alternative would be incompatible with the recently constructed segment of Maryland Route 36 to the south and the segment to the north, which is currently in final design. Estimated costs for Alternatives 1, 2, 2A, and 5 would be $36.2, $28.7, $27.9, and $38.1 million, respectively. POSITIVE IMPACTS: The proposed improvements would alleviate the impacts of through traffic, especially trucks, in Lonaconing. The project would allow traffic to move efficiently through the area and should ease traffic congestion and allow increased speeds, reducing the amount of air pollutants contributed per vehicle. Highway safety would also be improved. NEGATIVE IMPACTS: Alternates 1 and 5 would require the relocation of 23 and 19 families, respectively. Alternates 2 and 2A would result in the relocation of 43 and 42 families, respectively. Alternates 1, 2, 2A, and 5 would require the acquisition of 70.1, 35.0, 44.5, and 95.1 acres of woodlands; 0.27, 0.30, 0.13, and 0.04 acres of wetlands; and 9.1, 8.8, 5.0, and 0.7 acres of 100-year floodplains, respectively. Alternates 1 and 5 would each require five stream crossings, while Alternate 2 would require six stream crossings and Alternate 2A would require seven stream crossings. Alternates 2 and 2A would each require approximately nine acres of rights-of-way from the Lonaconing Historic District.

AN - 36400067; 681 AB - PURPOSE: Operation and maintenance of a nine-foot channel involving pool regulation, dredging, revetment, and bank line and dike maintenance on the Illinois and Mississippi rivers in Illinois and Missouri are proposed. The existing channel, extending from the mouth of the Missouri River to Minneapolis, would be dredged to a depth of 9 feet and a width of at least 300 feet. This draft supplement to the final environmental impact statement of June 1975 presents a plan designed to minimize conflicting resource uses associated with Pool 26. Navigation Pool 26 extends from the dam at Alton, Illinois for 38.5 miles up the Mississippi River to Lock and Dam 25 at Winfield, Missouri, and from the mouth of the Illinois River at Grafton, Illinois for 80 miles to the LaGrange Lock and Dam, approximately 19 miles north of St. Louis, Missouri. The specific area investigated by the shoreline management study for fleeting includes the 38.5 miles along the Mississippi River and the lower 5 miles along the Illinois River. The preferred plan would recommend 7.85 additional deep-water miles as potentially acceptable for fleeting. The sites would be located at Alton, Dresser Island, North Power Plant, Grafton, Mason Island, Gilbert Lake, Iowa Island, Golden Eagle Ferry, Two Branch Island, Sweden Island, Cuivre Island, and Sunset. Special conditions would be applied to each site to minimize adverse environmental impacts. POSITIVE IMPACTS: The preferred alternative would provide adequate space requirements for fleeting while minimizing adverse effects to nonnavigational resources. The plan also would serve as a guideline for making resource decisions on future fleeting permit applications. Endangered eagles and herons would be protected completely. NEGATIVE IMPACTS: Meeting fleeting requirements would produce moderate and minor adverse impacts to historic sites, visual qualities, and recreation areas.

AN - 36385311; 693 AB - PURPOSE: Flood control measures for Holliday Creek in Wichita Falls, Texas are proposed. The proposed action involves channelization of 7.9 miles of Holliday Creek from Lake Wichita dam to the Wichita River confluence. This supplemental information report presents an evaluation of the Clean Water Act, Section 404(b)(1) guidelines. Activities subject to these requirements include placement of soil-cement on the face of the existing dam and filling sections of realigned channel. The fill materials would consist of concrete, riprap, and the soil excavated from the channel. Approximately 5,000 cubic yards of concrete and 70,000 cubic yards of riprap would be used to line portions of the channel requiring stabilization. The face of the Lake Wichita dam would be reinforced with about 6,500 cubic yards of soil-cement, covering some 9,300 square yards of the lake below elevation 976.0 (normal pool). Nine oxbows, totalling 14,000 feet of existing stream channel, would be filled. The remaining oxbows would be plugged at the upper end and fitted with drop structures at the lower end to allow drainage. POSITIVE IMPACTS: Suspended particulates and turbidity would decrease on project completion due to erosion prevention. Placement of the fill in the oxbows would minimize the potential for sediment resuspension. The proposed action would not release contaminants into the water column. Erosion control practices used in the channel should decrease turbidity. The loss of riparian vegetation would reduce streambank shading and subsequently increase water temperature. NEGATIVE IMPACTS: The proposed action would alter all of the aquatic habitat in the section of Holliday Creek extending from Lake Wichita dam to the Big Wichita River confluence. The proposed action would reduce habitat diversity, and permanent biological communities would be limited to those capable of colonizing the monotypic habitat of the proposed channel. The project would increase the velocity of flood discharges entering the Wichita River. LEGAL MANDATES: Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Because of engineering expediencies and day-to-day accountability, the effectiveness of reservoir operations is typically measured by more easily monitored and dramatically responsive indicator parameters such as water temperature, iron and manganese concentrations, the presence or absence of dead fish, etc. Most scientists working in this field, however, are aware of or suspect that there are probably numerous additional, longer-term, direct, and sometimes subtly indirect consequences of streamflow regulation. In this perspective, the following paper examines some interrelationships that have become apparent to the Pittsburgh District among water quality, reservoir regulation, and a single species of aquatic plant (Justicia americana). Included in the discussion are secondary impacts associated with this plant that influence the physical form and substrate of stream channels and aquatic invertebrates, fishes, and other species of aquatic plants. While much of the specific information in this discussion may be esoteric to streams of upper Ohio River drainage, it provides some general insights pertinent to planning and evaluating environmental features of flood control channel modification projects, as well as demonstrating long-term indirect impacts that can result from water quality-quantity management activities.

Use of selective withdrawal outlet works, a relatively new water resources application, has helped to reduce the negative environmental impacts of dams on the Rogue River system. The Rogue River Basin Project of southwestern Oregon consists of Lost Creek Lake (completed in 1977), Applegate Lake (completed in 1981), and Elk Creek Lake (currently under construction). They are a system of multiple purpose dam projects that have reservoirs authorized for flood control, irrigation, hydropower, fish and wildlife enhancement, water supply, and water quality. Lost Creek Dam has single wet well outlet works while the Applegate Dam has a double wet well structure. The Elk Creek selective withdrawal structure is currently being physically modeled with a single wet well.

In each case the skimming weir was not included in the initial design, but was added in response to water quality problems that surfaced during the final phases of construction. This paper describes the events that led to the construction of skimming weirs at two lakes with hydropower installations. Field data show the weirs to be effective in limiting the release of cold deoxygenated water from the hypolimnion over a significant range of pool elevations and discharge rates.

Some of these models can even make operational decisions regarding proper gate regulations to obtain a desirable water quality condition at a dam site for a given set of flow conditions. HEC-5Q, Simulation of Flood Control and Conservation Systems (Including Water Quality Analysis) computer model, has the unique capabilities to accept user-specified water quantity and quality needs system-wide and to decide how to regulate the network of reservoirs. The decision criteria are programmed to consider flood control, hydropower, instream flow (municipal, industrial, irrigation, water supply, fish habitat) and water quality requirements. The HEC-5Q program was first applied to the Sacramento River system in California and a report was published in July 1985. Two other applications are in progress, the Kanawha and Monongahela River systems, and are expected to be completed by September 1986. A brief description of the HEC-5Q concepts and these three applications will be discussed below.

Indiana Harbor is the fourth busiest port on the Great Lakes, having a deep draft navigation channel maintained by the USAGE. The Grand Calumet River, which is tributary to Lake Michigan via the Indiana Harbor and Canal, has a relatively small watershed which is entirely urban/industrial. The major industries along the canal are steel, petrochemical, lead, and gypsum. The Brand Calumet River/Indiana Harbor Canal has a long history of water quality problems and has been identified by the International Joint Commission of the Great Lakes (IJC) as a major area of concern.

AN - 36401333; 625 AB - PURPOSE: Construction of an interchange at the intersection of Yerba Buena Road and U.S. Highway 101, construction of a bridge to carry Yerba Buena Road over Coyote Creek, and widening of a short section of Sylvandale Avenue are proposed to complete Yerba Buena Road /Sylvandale Avenue as an arterial connection in the Evergreen area of San Jose, California. The first component of the project would involve widening Sylvandale Avenue from two to three lanes between Senter Road and Yerba Buena Road in the vicinity of Sylvandale Junior High School. The second component would involve construction of a two-lane bridge with a width of 50 feet to accommodate the two lanes and two eight-foot shoulders and two five-foot sidewalks. The third component of the project would involve construction of an undercrossing and full interchange at the intersection of Yerba Buena Road and U.S. 101. The undercrossing would have four through lanes, a left-turn lane, bicycle lanes, and sidewalks. Due to the proximity of the interchange to the existing Capitol Expressway /U.S. 101 interchange, the project would incorporate a system of ramps and collector/distributor frontage roads to minimize the number of entrances to and exits from the freeway. Cost of the project is estimated at $20.9 million. POSITIVE IMPACTS: Completion of the Yerba Buena Road/Sylvandale Avenue arterial connection from Senter Road to San Felipe Road would improve traffic circulation, delivery of trucks, and police service; reduce pollutant levels in the immediate area; and further the San Jose General Plan and California Urban Strategy Plan. Reserve roadway capacity would be available to accommodate traffic if peak-hour trip reductions were not achieved or more trips are generated in the Evergreen area as a result of delay in industrial development. NEGATIVE IMPACTS: Excavation in association with the project could result in the loss of archaeological artifacts located in the area, particularly in the vicinity of Coyote Creek. The removal of trees and vegetation would degrade area aesthetics, and grading for the Coyote Creek bridge could increase erosion. The interchange and bridge structure would be subject to strong ground shaking and potential liquefaction during an earthquake on one of the regional faults. Substantial increases in noise levels along Yerba Buena Road and Sylvandale Avenue would occur as a result of higher traffic volumes. The project would remove land from the Sylvandale Junior High School recreational field, and a portion of Ramblewood Park would be displaced by an off-ramp from southbound U.S. 101. The bridge would be constructed over the Coyote Creek Parkway Chain, an open-space area.

Preparation date: January 31, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - COOS BAY, OREGON DREDGED MATERIAL DISPOSAL SITE DESIGNATION. AN - 36386370; 637 AB - PURPOSE: Designation of two interim designated Ocean Dredged Material Disposal Sites (ODMDS) and the designation of a new ODMDS off Coos Bay, Oregon are proposed. The two designated existing ODMDSs would be used for the disposal of large-grained sediments (dredged material), while the new site further offshore would be used for the disposal of finer sediments with higher volatile solids content. The purpose of the action is to provide environmentally acceptable areas for the disposal of dredged material, in compliance with the Environmental Protection Agency (EPA) Ocean Dumping Regulations and Criteria. The preferred alternative would designate three sites off Coos Bay, Oregon for the disposal of dredged material: interim disposal sites E and F, and site H, with a centroid at approximately 31 fathoms. Sites E and F are located approximately 1.5 statute miles offshore of the entrance to Coos Bay at depths of 10 and 12 fathoms, respectively. Site H is located approximately 3.7 miles offshore at a depth of 30 fathoms. Type 1 sediments are predominantly clean sand of marine origin. Type 2 sediments are finer-grained sand and silt containing some volatile solids. Type 3 sediments are highly organic fine material containing 6 to 20 percent volatile solids. The recommended use of these sites would be disposal of type 1 material at sites E and F and disposal of types 2 and 3 material at the site H location. POSITIVE IMPACTS: Environmentally acceptable ocean areas would be provided for the disposal of dredged material. Planning for dredged material disposal would be enhanced since permanently designated ocean disposal sites are available for comparison with other dredged material disposal alternatives. Ocean disposal is important to the present channel maintenance program. NEGATIVE IMPACTS: Some bottom organisms would be buried and lost within the sites. Mounding, changes in sediment texture, and disturbance of demersal fish would be temporary, minor, and restricted to the sites. Volatile solids and chemical contaminants found in upper bay sediments would temporarily impact water quality in the vicinity of the disposal sites. Loss of benthic organisms would at least temporarily remove a food source for organisms higher in the food chain. Permanent designation of the proposed sites for disposal of dredged material would commit the sites and their resources primarily to that use. Other uses such as oil and gas exploration, and to a certain extent, mining, fishing, and use by certain aquatic species, would be precluded.

Preparation date: January 31, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - PROPOSED PLAN FOR FLOOD DAMAGE REDUCTION ON MAYFIELD CREEK, GRAVES, MCCRACKEN, BALLARD, AND CARLISLE COUNTIES, KENTUCKY. AN - 36398494; 642 AB - PURPOSE: Implementation of a plan for flood damage reduction on Mayfield Creek is proposed. The Mayfield Creek Basin is located in the Purchase Area of western Kentucky and encompasses all or portions of Graves, McCracken, Ballard, and Carlisle counties. Three alternatives are proposed. Plan A consists of vegetative clearing and snagging from stream mile (SM) 0.0 to SM 25.6. Vegetation between existing top banks that presently, or would likely in the future, obstruct stream flow would be removed to increase the stream carrying capacity of the channel. Over-bank clearing would be from one side only to provide access for channel modification and for disposal of material removed from the channel. Vegetative matter removed from the channel would be burned on-site. Plan B consists of selective clearing and snagging of vegetation and debris from the mouth to mile 25.6 as required. Sediment would also be removed from the main channel from SM 11 to SM 13.5. In addition, a low-water weir would be constructed and placed in the main channel at SM 13.8 (approximately 1,500 feet downstream of Wilson Creek) to divert low flows to the old channel meander in order to maintain the existing fishery habitat. The removed material and sediment would be deposited along one bank of the stream and would be used to create an embankment at the site of excavation. The removed woody material would be burned. Plan C consists of channel enlargement of the main channel from SM 8.16 to SM 25.6. Vegetation would be removed from within and very near the top banks of the channel. The improved channel would have a bottom width ranging from 60 to 90 feet. The excavated sediment would be deposited in even lifts along the top banks of Mayfield Creek. With this plan, a low-water weir would be constructed at SM 13.52 and placed in the main channel just downstream of the confluence of Wilson Creek. The stream bottom configuration of the main channel would be changed as a result of channel deepening and widening. The estimated average annual equivalent cost would range from $192,300 to $933,900 for channel enlargement, with benefit/cost ratios of 4.0 for vegetative clearing and snagging, 4.4 for channel restoration, and 0.98 for channel enlargement. Plan B is tentatively recommended as a basis for preparation of plans and specifications and subsequent project construction. POSITIVE IMPACTS: The reduction of flood levels and flood duration would decrease disruption of public services and facilities. A potential hindrance to community and regional growth would be removed by reducing the frequency and duration of flooding and indirectly by increasing agricultural production within the area. Additional employment opportunities would be generated by construction and increased agricultural activity. Approximately 960 acres of dead and dying timber would be converted to bottomland hardwoods or agriculture. The conversion of dead and dying timber and shrub swamp areas to bottomland hardwood would generate a net increase in recreational activity. There would be a net gain in agricultural land due to land conversion and clearing, and a slight increase in property tax revenue from higher assessments and taxes on properties. NEGATIVE IMPACTS: Removal of instream bank vegetation and physical activities associated with snagging would result in short-term increases in stream turbidity, stream sediment loads, lowered dissolved oxygen levels, increased nutrients, and increased pesticides and heavy metal levels. One-sided channel enlargement would have significant long-term impacts on all water quality parameters. Drainage and loss of swamp nursery areas would occur. There would be a species composition change due to the drier nature of the basin. Rights-of-way acquisition and use of heavy equipment would affect archaeological sites. The aesthetic quality of the basin would be reduced by conversion of bottomland hardwoods and wetlands for agricultural expansion. Air quality would deteriorate throughout the area as a direct result of construction, land clearing, and increased agricultural activities.

AN - 36403594; 643 AB - PURPOSE: Construction activities on approximately 230 miles of channels, accelerated land treatment practices on approximately 16,000 acres of cropland, and accelerated technical assistance in the Riverside-Black Bayou Watershed in Bolivar and Washington counties, Mississippi are proposed. The plan consists of accelerated technical assistance for land treatment on 13,810 acres of cropland; increasing the capacity of 1,312 miles of channels by enlargement, realignment, or removal of sediment and vegetation together with stabilization practices; and installing stabilization practices on an additional 99 miles that are otherwise adequate and water level control structures where channels could adversely affect wetlands. The land treatment program consists of accelerated technical and financial assistance to watershed land users during the installation period. Approximately 6.2 person years of effort would be provided to land users to assist in the installation of these land treatment measures. Technical and financial assistance would be provided to install approximately 510 grade stabilization structures on some 85 miles of existing on-farm channels (mains and laterals) throughout the watershed. Technical assistance would provide for the treatment of approximately 16,000 acres of continuous crops in the drainage areas of the project channels. Channel practices would consist of approximately 33 miles of channel enlargement, 41 miles of clearing and shaping, 53 miles of channel clearing, 4 miles of new channel, and 99 miles of existing channel to be stabilized with side inlet grade stabilization structures (overfall pipes). Where channels intercept wetlands, water level control structures would be installed through levees to prevent the draining of wetlands below the normal low summer level. Eighty acres of permanent trees and shrubs would be established on channel berms and spoil areas. The total estimated cost would be $10.9 million. POSITIVE IMPACTS: Installation of the preferred alternative would reduce flooding and poor drainage on 81,000 acres of cropland. Erosion rates would be reduced an average of 3.2 tons per acre on approximately 16,000 acres of cropland. Sediment entering channels and wetlands would be reduced by 43,000 tons per year (22 percent). To reduce the impact on waterfowl habitat, 16 water level control structures would be installed. These structures would allow the flooding of croplands during winter months and create waterfowl resting and feeding areas. Improved drainage would allow an additional 14,800 acres to be classed as prime farmland. Quality of life would be improved due to an increase in net income and an increase in the number of jobs created by construction of the project. Average annual benefits of $2.4 million would accrue from reduced flooding and improved drainage. Net benefits would be $1.2 million annually. Damages from over-bank flow would be reduced from $951,000 to $281,000. NEGATIVE IMPACTS: Of the 17,400 acres of wetlands in the watershed, 90 acres would be lost to construction. Some wildlife habitat would be affected. LEGAL MANDATES: Executive Order 11990, Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.), and Fish and Wildlife Coordination Act of 1958, as amended (16 U.S.C. 661 et seq.).

AN - 36392261; 647 AB - PURPOSE: Land treatment and water management measures are proposed for the 994,800-acre Wolf and Loosahatchie river basins in Fayette, Hardeman, Haywood, Shelby, and Tipton counties, Tennessee and in Benton, Marshall, and Tippah counties, Mississippi. The preferred alternative for land treatment would increase erosion control practices on 130,690 acres of cropland, 2,320 acres of gullies and degrading ditches, and 840 acres of roadbanks. Practices for cropland would include rotations, no till, strip cropping, terrace systems, and conversions to hay production and trees. Installation cost for land treatment practices on cropland is estimated at $11.2 million. Land treatment measures for stabilization of gullies and degrading ditches would include sediment basins, shaping, and vegetative planting. The installation cost for gully and ditch treatment is estimated at $927,600. Practices for control of eroding roadbanks would involve shaping and vegetative planting, with an installation cost of $822,320. The average annual benefits and costs are estimated to be $5.8 million and $1.1 million, respectively, resulting in a benefit/cost ratio of 5.28. The water management plan is a program for flood damage reduction, water quality improvement, additional recreational opportunities, and environmental enhancement in the Wolf and Loosahatchie river basins. The plan would include project measures for hand clearing and debris removal on the main stems of the two rivers and selected tributaries. It would also provide for the establishment of four access points with basic facilities to enhance canoeing opportunities on 45 miles of the Wolf River. The average annual cost is estimated at $179,910. Annual benefits are estimated at $245,970, resulting in a benefit/cost ratio of 1.37. The total estimated cost for flood prevention and recreation is estimated at $1.4 million. POSITIVE IMPACTS: The land treatment plan would provide adequate protection for 133,850 upland acres and would reduce annual gross erosion by 9.9 million tons. Approximately 31,000 acres of cropland would be converted to grass and trees, reducing topsoil losses. Farming efficiency and profits would be enhanced. Water quality would be improved, and wildlife food and cover sources would be increased. The water management plan would have a beneficial impact on 27 acres of flood-sensitive species and 700 acres of wetlands. Stream habitats would be increased by 97 aquatic habitat units by restoring surface flow on 380 acres of streambed. Wildlife habitat would be enhanced by 18 habitat units of bottomland hardwood habitat on 504 acres. Opportunities for canoeing on the Wolf River would be enhanced. NEGATIVE IMPACTS: There are no adverse effects to the environment due to the proposed land treatment and water management measures. LEGAL MANDATES: Public Law 87-639.

AN - 36396452; 638 AB - PURPOSE: Final designation of the existing ocean dredged material disposal site for Georgetown Harbor, South Carolina is proposed. The one-square-mile site lies three miles offshore from the mouth of Winyah Bay on the south side of the channel in 20 to 36 feet of water. Annual dredging of the Georgetown Harbor Entrance Channel removes an average of 450,000 cubic yards of material. No changes in current disposal practices are anticipated. POSITIVE IMPACTS: The existing ocean dredged material disposal site has not undergone mounding, degradation of water quality, or significant alteration of benthic communities during 30 years of entrance channel materials deposits. Relocation of the site might adversely affect loggerhead turtle nesting and shellfishing areas and would increase costs. NEGATIVE IMPACTS: Consequences of the existing site designation would be limited mainly to smothering of aquatic organisms by burial and temporary increases in turbidity.

Preparation date: January 17, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - DISCHARGE OF DREDGED AND FILL MATERIAL FOR THE KWAJALEIN ATOLL CAUSEWAY PROJECT, KWAJALEIN ATOLL, MARSHALL ISLANDS. AN - 36400451; 636 AB - PURPOSE: Authorization to discharge dredged and fill material in conjunction with the Kwajalein Atoll Causeway Project, Kwajalein Atoll, Republic of the Marshall Islands is proposed. The proposed action would involve the discharge of coralline fill during the construction of a revetted, coralline fill causeway that would connect the six islands north of Ebeye. Unconsolidated sand, coral, and rubble fill material would be dredged from 19 sites in the lagoon. The quarries would be compartmentalized to prevent along-shore currents and would be situated a minimum of 200 feet from the reef edge and the islands or causeway centerline to reduce any erosional effects caused by the quarry depressions. To access the quarries, a temporary spur road would be constructed at right angles to the main causeway, which would provide a haul road for construction equipment. On the ocean side, hydraulic excavators working directly on the reef during favorable tide levels would mine armor stone from the drilled and blasted hard coral. Spoils from this operation would be used to construct the initial spur road. Larger spoils and material to be used for underlayer stone would be used for erosion protection. As one area is mined out, the spur would be transferred up the causeway 60 to 70 feet by the excavator and the next section would be quarried. Core and bedding material would be obtained from lagoon side deposits of loose, unconsolidated rock and coral fragments. A floating clamshell and /or dragline would be used to excavate this material, with the material loaded onto a barge for transport from the dredge site to one of the islands, where it would be offloaded using a conveyor belt and transferred to dump trucks for transport to the causeway. Box culverts through the causeway would allow water to pass over the reef flat from the ocean to the lagoon. Utility systems to support the development plans would be extended from Ebeye along the causeway. Estimated first cost of the project would be $12.1 million. Estimated annual costs would be $345,000. POSITIVE IMPACTS: The proposed action would make available 144 acres of land for population dispersion and for subsistence agriculture and economic development. Deeper areas left on the reef flat as a result of quarry operations would increase species diversity and abundance and fishing activity and potential. NEGATIVE IMPACTS: The causeway would modify 27 acres of seaward reef flat and 17 acres of lagoon slopes. Fourteen acres of existing fast land would be modified by road construction. Armor stone would be quarried from 20 sites on the seaward reef flat. The planned land development would destroy some Japanese ruins. Nesting and roosting by sea birds would be discouraged. Native vegetation would be replaced by exotic or agriculturally preferred vegetation, and the mangrove area on Ninge could be filled. Any alternative involving fill material would result in a modification of the reef environment. Work on the reef flat would result in the loss of some organisms and temporary water turbidity. The project could result in an increase in automotive traffic in the project area.

Preparation date: January 15, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - RELOCATION OF U.S. ROUTE 422 FROM THE CITY OF SOLON, CUYAHOGA COUNTY, THROUGH BAINBRIDGE AND AUBURN TOWNSHIPS, GEAUGA COUNTY, OHIO: CUY-GEA-422-18.40-0.00 AND 3.19. AN - 36402676; 627 AB - PURPOSE: Construction of an 11.5 mile, east-west section of U.S. Route 422 on new alignment in Cuyahoga and Geauga counties, Ohio is proposed. Approximately 2.4 miles of the facility would be located in the city of Solon in Cuyahoga County, 4.9 miles in Bainbridge Township, and 4.2 miles in Auburn Township in Geauga County. The proposed project would begin just east of an existing interchange at State Route (S.R.) 91 (S.O.M. Center Road) in Solon, Ohio and extend to just east of S.R. 44 in Auburn Township to connect with the LaDue Reservoir causeway. The new facility would consist of a 4-lane limited-access freeway with a 60-foot grass median. Each lane would be 12 feet wide. Paved shoulders would be provided for emergency parking. The entire length of the facility would be fenced. Rights-of-way would average 300 feet wide, depending on the terrain and whether the highway section is in cut or fill. Interchanges would be provided at Chillicothe Road (S.R. 306) and at Ravenna Road (S.R. 44) allowing access and egress for both east- and westbound traffic. Approximately 30 percent of the facility would be at grade, 32 percent in cut, and 38 percent above grade. Fourteen bridges would be constructed as part of the proposed action. Service roads would be provided from Liberty Road north of and paralleling the proposed alignment for one mile east and at Snyder Road south of and paralleling the proposed alignment for 0.6 mile east. Service roads would be constructed to connect with Chagrin Road to maintain access for residents on West View Drive north of the alignment and for residents on Millbrook Drive south of the alignment to connect with Bainbridge Road. Estimated construction cost of the entire proposed project is $54.6 million. POSITIVE IMPACTS: The project would result in improved access and traffic circulation and increased motorist safety on adjacent routes now used for access to U.S. Route 422. Improved access would be provided for emergency vehicles and to LaDue Reservoir, Sea World, and Geauga Lake parks. The project might enhance development, resulting in increased tax revenues for the area. Noise levels would be reduced on existing roads. New edge habitat would be created. NEGATIVE IMPACTS: A freeway facility would be introduced into a relatively undeveloped portion of Geauga County. The facility would be expected to accelerate the already occurring land use changes from rural to low-density single housing. Noise levels would increase along the project corridor. Approximately 2,800 feet of channel modification of year-round flowing streams would be required. The permanent loss of 312 acres of prime farmland, of which 218 acres are wooded, would result from the project. Wildlife would be displaced, and 251 acres of woodlands, 127 acres of agricultural land, vacant land, and old field habitat would be lost. The project would take 6.5 acres of wetlands. Rights-of-way have been purchased, and 40 persons, one business, and a township maintenance facility have been successfully relocated. The proposed project may require the discharge of dredged or fill material into streams, wetlands, or other waters.

AN - 36393005; 635 AB - PURPOSE: Disposal of dredged materials resulting from maintenance dredging of navigation channels within Mobile Bay, Mobile County, Alabama is proposed in this supplement to the final environmental impact statement of July 1974. Currently, the three existing disposal sites of North and South Blakeley islands and North Pinto Island receive approximately 2.8 million cubic yards of dredged material on a biennial dredging cycle basis, a rate that interferes with dewatering and compaction of the dredged material. Five alternatives are under consideration. Alternative A involves retaining the existing sites and raising the height of the diked areas. Unit cost per cubic yard of dredged material would be $2.50. Under Alternative B, the existing 238-acre Alcoa bauxite disposal facility on Blakeley Island would receive 664,600 cubic yards of dredged material annually and the remainder would continue to go to the existing disposal sites. Unit cost for disposal would be $1.86 per cubic yard. Alternative C would involve establishment of a new 1,000-acre unconfined open-water site on bay bottom in the northern bay near Hermit Island (Battery McIntosh). An annual average amount of 664,000 cubic yards of dredged material would be delivered by floating pipeline, and the remaining 765,400 cubic yards would be placed in the existing disposal sites. Unit cost of this alternative would be $1.93 per cubic yard of dredged material. Under Alternative D, the existing diked disposal areas would receive some dredged material from the Upper Mobile Harbor, while the rest of the material would be placed in an unconfined open-water disposal area currently used for disposal of dredged material from the adjacent Mobile Ship Channel. Disposal of material from this ship channel would be stepped down to disposal areas further south. Unit cost of this alternative would be $2.57 per cubic yard of dredged material. Alternative E would involve disposal of all dredged material at two open-water sites, designated Mobile-north and Mobile-south, in the Gulf of Mexico, at a unit cost of $2.57 per cubic yard of dredged material. POSITIVE IMPACTS: Alternatives B through E would create disposal sites providing 40 years of disposal capacity. NEGATIVE IMPACTS: Alternative A would offer only 10 years of disposal capacity, and Alternative E would be cost-effective for Upper Mobile Harbor sediments only if the channel-deepening project were implemented. Alternative B would involve the loss of 238 acres of previously altered marginal wetlands habitat. Alternative C would alter 1,000 to 1,400 acres of bay bottom habitat, and Alternative D would increase the frequency of disturbances at mid-bay disposal sites.

AN - 36398842; 696 AB - PURPOSE: This final supplement to the final environmental impact statement of September 1981 addresses modifications to the original flood control plan. The channel alignment at Hagen Road would be straightened for a distance of 400 feet to improve hydraulic flow, and the sharpness of the channel curve upstream of Ward Avenue would be reduced to improve hydraulic flow and to reduce costs. The trapezoidal channel in the vicinity of Broadway Place would be replaced with a concrete U-shaped channel. The terminus structure would be realigned to avoid major impacts on an archaeological site, would be tipped slightly to the east, and would include a flared outlet. The permanent sedimentation pond feature would be eliminated, but during construction the terminus structure would be operated temporarily as a sedimentation pond. Portions of lower Pammel Creek would be riprapped, and approximately two acres of floodplain forest would be cleared for an overflow area to provide adequate slope for drainage. Following removal of the earth obstruction, the overflow area would be revegetated. Estimated cost of the entire project is $3.1 million, and the benefit-cost ratio is 1.16. POSITIVE IMPACTS: The channelization project would permit residential and commercial use of the floodplain, which would have been used for agricultural purposes or remained vacant without the project. Project modifications would improve hydraulic flow, reduce costs, and protect a recently identified significant archaeological site. NEGATIVE IMPACTS: Approximately three acres of floodplain vegetation would be removed, and the composition of riparian species within the channel would be altered. The configuration of the channel as it passes through adjacent wetlands would be changed. The turbidity and associated sediment load of coulee water as it discharges into the Mississippi River would increase during the construction period.

Preparation date: January 3, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - LAKE DARLING DAM FLOOD CONTROL PROJECT, SOURIS RIVER, RENVILLE, WARD, MCHENRY, AND BOTTINEAU COUNTIES, NORTH DAKOTA. AN - 36393236; 691 AB - PURPOSE: Implementation of a flood control project for the Souris River, located in Renville, Ward, McHenry, and Bottineau counties, North Dakota, is proposed. The Souris River headwaters are located in the Canadian province of Saskatchewan. The river crosses the international border near Sherwood, North Dakota and makes a 358-mile loop before entering the province of Manitoba near Westhope. The proposed flood control plan would raise the Lake Darling design pool by approximately four feet and add flood control measures upstream and downstream of the dam. Other features would include flood control measures at Velva, Sawyer, and six subdivisions between Burlington and Minot; flood protection measures for McKinney Cemetery and Renville County Park; flood proofing or acquisition of rural residences; acquisition of flowage easements downstream of the dam; modification of the U.S. Fish and Wildlife Service structure in the Upper Souris National Wildlife Refuge and the J. Clark Sayler Refuge; fish and wildlife features; monetary compensation to Canada for altered return flows; and a flood warning system for Gassman Coulee. For a maximum reservoir pool of elevation 1,605, the crest of the raised dam would be at elevation 1,614. The spillway would be located on the left abutment. The low-level outlet works would consist of four gate-controlled conduits located in the spillway piers. A public bridge would cross the spillway, and approach roads would be raised. The McKinney Cemetery would be protected by a levee around the riverward edge. Renville County Park would be provided 100-year flood protection with a channel cutoff and left bank levee with tiebacks into high ground upstream and downstream of the park area. A 3,000-gallon per minute pumping station would be provided, and the interior channel would provide pond storage capacity. Eckert Ranch would be protected with a levee instead of acquisition of the building. Downstream measures would include upgrading existing temporary levees and providing interior drainage facilities for residential areas at Velva, Sawyer, and six subdivisions between Burlington and Minot. An automated flood warning system on Gassman Coulee would consist of two precipitation gauges and two stream gauges, with data encoders and radio transmitters in the upper and lower portions of the Gassman Coulee watershed, plus a receiving station located in Minot. Structures in the Upper Souris and J. Clark Sayler National Wildlife refuges, including service roads, ponds, fishing areas, boat launching facilities, and a carp control structure, would be modified. Total cost of the project would be $63.7 million, with a benefit-cost ratio of 1.77. POSITIVE IMPACTS: The Lake Darling project would reduce flood damages in Minot, Velva, Sawyer, other urban areas, and rural lands along the Souris River. No land acquisition would be required for mitigation of the Lake Darling project. NEGATIVE IMPACTS: The Highway 5 bridge would be unusable for up to 146 days for heavy military vehicles and up to 22 days for passenger vehicles. Grano Crossing, Highway 28, and the Soo Line Railroad crossing would also be affected. Movement of farm products, commercial activities, school children, and normal social activities would be subject to time-consuming and costly detours. Minot Air Force Base would experience curtailment of its ability to maintain and protect its nuclear missile sites for up to 146 days. Water level fluctuations in Lake Darling could adversely affect floodplain forests and agricultural lands. Approximately 11,000 acres of downstream lands could be flooded for two weeks longer than in the present condition.

Preparation date: January 3, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - NAVIGATION STUDY AND FEASIBILITY REPORT FOR PORT SUTTON CHANNEL, FLORIDA. AN - 36392225; 641 AB - PURPOSE: Improvement of the existing deep-draft terminal channel at Port Sutton, Florida for commercial navigation is proposed. Port Sutton is on the northeast side of Hillsborough Bay in Tampa Bay on the west coast of central Florida. The Port Sutton Terminal Channel is an east-west waterway connecting with the west side of the Port Sutton turning basin, enabling access to terminal facilities of the port. The preferred alternative provides for a channel 3,300 feet long with a bottom width of 200 feet at a depth of 43 feet. The selected plan would involve the removal of approximately 305,000 cubic yards from 15 acres on the bottom of the terminal channel. The excavating equipment would likely be a pipeline dredge, with disposal in a diked area of about 25 acres. The excavation quantities include one foot of overdepth allowance for dredging inaccuracies, with a 2-foot required overdepth in rock. The material to be removed is a varying mixture of rock, sand, silt, and clay with an overall high percentage of fines making it unsuitable for landfill. The average side slope resulting from the excavation is estimated at 1 foot vertical to 3 feet horizontal. The Tampa Port Authority will be responsible for the construction of the disposal area dikes and land acquisition. The dikes will include discharge weirs to control turbidity. Dike heights will be approximately 14 feet high with a crown width of 6 feet and 1 on 3 side slopes. Material for dike construction will come from within the proposed disposal area. The estimated cost to construct the preferred alternative is $2.4 million, based on an estimated time of 4.5 months to complete the work. The benefits of the selected plan exceed the cost by $748,000 annually. The benefit-to-cost ratio of 4.1 to 1 is equal to the total average annual benefit of $992,000 divided by the total average cost of $244,000. POSITIVE IMPACTS: Navigation improvements within Port Sutton would encourage development of cargo and handling facilities. The depth of the channel would accommodate the majority of the economically loaded bulk carrier vessels seeking entrance into Port Sutton at present and in the future. NEGATIVE IMPACTS: The proposed plan would have the potential of injuring manatees by boat collisions and propeller lacerations during project construction activities. Upland bird, rodent, and snake habitat would be lost. LEGAL MANDATES: Executive Order 11990 and Federal Water Pollution Control Act of 1972 (33 U.S.C. 1251 et seq.).

Preparation date: January 3, 1986 N1 - Last updated - 2011-12-16 ER - TY - RPRT T1 - MILL CREEK INTERIM FEASIBILITY REPORT, METRO REGION OF NASHVILLE, TENNESSEE. AN - 36386401; 692 AB - PURPOSE: Construction of two dry dams on Mill and Sevenmile creeks and channel widening on Sevenmile Creek for flood control in the metro region of Nashville, Davidson, and Williamson counties, Tennessee are proposed. The dry dam on Mill Creek would be constructed below Old Hickory Boulevard at Mile 16.81; would have a bottom elevation of 512 feet, a top elevation at 550 feet, and a length of 1,000 feet; and would have a base width of 49 feet, with a 10 by 10 foot box culvert at streambed. The maximum area of inundation would be approximately 680 acres. The maximum retention time for the 100-year flood event is less than three days. The ponding area would extend from Mile 16.81 to approximately Mile 21.0. The dry dam on Sevenmile Creek would be constructed at Mile 3.70 and would innundate approximately 113 acres at full pool. Maximum retention time for a 100-year flood event is estimated to be two days. The top of the dam would be at elevation 547 and would extend 28 feet from the bottom streambed elevation of 519. The pool, if full, would extend from Mile 3.7 to Mile 4.4. The base of the dam would be 39 feet wide with a 6 by 6 foot box culvert at streambed. The dam would be 900 feet long and would rest on 0.53 acre. The existing channel would be widened from Sevenmile Creek Mile 0.70 to Mile 1.51. The channel excavation would be approximately two feet above the present streambed and would be conducted primarily along the right bank, providing a minimum channel width of 75 feet at the lowest cut elevation. Approximately 3.9 surface acres would be removed to obtain a minimum 75-foot channel width. A disposal site would be required for the material excavated from the two dam sites and the channel widening. The proposed disposal area is in a previously cleared site that could be as large as 1.9 acres. Periodic maintenance of the Mill and Sevenmile creeks dam structures and temporary ponding areas and the widened section of Sevenmile Creek would be required. POSITIVE IMPACTS: Beneficial impacts would result from relief from flooding, reduced erosion, and scouring of floodplains. The potential for impacts from future floodplain encroachment would be reduced. Downstream flooding impacts would be reduced, with a positive impact for businesses, industries, and residences in the downstream locations. NEGATIVE IMPACTS: Adverse impacts would result from loss of vegetation and a slight increase in water temperature. There would be temporary loss of cover, food, and travel corridor by elimination of riparian habitat along a 0.75 mile streambank length, as well as a loss of 49 and 39 foot lengths of natural stream substrate due to the box culverts. Habitat within the ponding area would be temporarily lost during flood events. Dam construction would eliminate 0.8 and 0.5 acres from urban development. Up to 14 families would be relocated. Natural areas would be replaced by dam sites. A total of 3.9 surface acres along the stream would be removed and dedicated to flood prevention use.

The applications and the properties of the three methods are discussed and it is concluded that (1) the particular question of waste management determines the selection of the appropriate method of analysis; and (2) the direct waste analysis is useful to determine the contents of some materials in MSW, the waste product analysis is well suited to analyse elemental concentration in MSW, and the market product analysis is the most inexpensive and efficient method to give material and elemental concentrations of MSW if production figures are available.

This results in a need for Corps of Engineers districts to be able to predict the contamination of animals that may be associated with potential disposal alternatives: open-water disposal, upland disposal, and wetland creation. The following is a summary of the results of bioassay procedures using the earthworm Eisenia foetida to evaluate the potential contaminant mobility into soil-dwelling animals. These tests were derived from proposed Organization for European Common Development (OECD) and European Economics Commission (EEC) test procedures (evaluating the effects of new chemicals) and modified to consider accumulation and sublethal effects rather than toxicity.

Some of these models can even make operational decisions regarding proper gate regulations to obtain a desirable water quality condition at a dam site for a given set of flow conditions. HEC-5Q, Simulation of Flood control and Conservation Systems (Including Water Quality Analysis) computer model, has the unique capabilities to accept user-specified water quantity and quality needs system-wide and to decide how to regulate the network of reservoirs. The decision criteria are programmed to consider flood control, hydropower, instream flow (municipal, industrial, irrigation, water supply, fish habitat) and water quality requirements. The HEC-5Q program was first applied to the Sacramento River system in California and a report was published in July 1985. Two other applications are in progress, the Kanawha and Monongahela River systems, and are expected to be completed by September 1986. A brief description of the HEC-5Q concepts and these three applications are discussed. JF - Technical Papers.

If the input of an element into the furnace M is taken as 100%, the following partitioning was observed: carbon, slag 1.6%, ESP-dust 0.4%, flue gas 98%; sulphur 34, 26, 40; fluorine 34, 39, 27; chlorine 13, 20, 67; iron 99, 1, 0.02 ; copper 89, 10, 1; zinc 51, 45, 4; lead 58, 37, 5; cadmium 12, 76, 12; mercury 4, 24, 72. The comparison of incinerators M, B and others indicates that the fate of metals during combustion, gas cooling and gas cleaning is determined by the composition of the municipal waste, the properties of the individual metals, and the operating conditions of the incinerator. In order to improve waste incineration, it is necessary to understand better the physical-chemical processes taking place in an incinerator, and to apply this knowledge to the construction and operating of such a plant.

The great River Environmental Action Team (GREAT) I study was organized in 1973 to identify and assess the problems associated with multipurpose use of the Mississippi River. One of the main products of the GREAT I study was 40-year channel maintenance plan for the river. The project discussed in this supplement would implement the general channel maintenance paln for lower pool 5 on the Upper Mississippi River, including the rehabilitation of the 4,000-acre backwater lake, Weaver Bottoms. The primary objectives of the project are to develop a 40-year channel maintenance plan for lower pool 5, reduce maintenance dredging requirements in lower pool 5, and restore the habitat quality to the Weaver Bottoms area, by modifying side channels and constructing islands with maintenance-dredged material.

The plan formulation and evaluation were guided by the problems that were identified and summarized in the Problem Appraisal Report dated February 1985. This report supports a number of recommendations that center on a recommendation to test a modified operation plan. The recommended operation plan would improved project contributions to the authorized purposes of flood control and pollution abatement, although the pollution abatement requirements in the basin have significantly reduced in scope since the project was authorized. Present needs for fish and wildlife, instream flow, shoreline stabilization, cultural resources, and recreation would be addressed by the recommended operation plan and supporting structural features.

The quantities were then multiplied by the appropriate unit prices, summed and corrected for variations in local labour and materials costs and inflation to obtain the cost of the project. A worksheet for calculating costs using this procedure is explained. Predicted costs of 51 projects were within an average of 16 per cent of actual costs.

Reliability in achieving long-term safe yield and in preventing floods was generally achieved but reliability in the sense of frequency of achieving target flows had not been well studied as an objective in the design of reservoirs or in the determination of operating rules. Reservoir performance was studied in terms of the maximal shortfall from the target (system vulnerability) and the maximal number of consecutive periods of deficit during a record (system resilience). A model was developed using multiobjective mixed-integer linear programming. Tradeoffs between reliability, vulnerability and resilience were examined. As reliability was increased or as resilience increased, the vulnerability of the water system to larger deficits increased.

A geographic information system was used to store data on the river and riparian area and site-attractiveness mapping was used to identify potential new sites. The least costly combination of these sites and the best sequence for acquisition was identified with a branch-and-bound enumeration procedure. This procedure permitted direct use of a network-flow programming model for cost evaluation. The role of the models in plan formulation is considered.
