No. B-2873 Bridge No. 256 is included in the NCDOT 1997-2003 Transportation Improvement Program. The location is shown in Figure 1. No substantial environmental impacts are anticipated. The project is classified as a Federal "Categorical Exclusion". I. SUMMARY OF ENVIRONMENTAL COMMITMENTS 1. All standard procedures and measures, including NCDOT's Best Management Practices for Protection of Surface Waters, will be implemented, as applicable, to avoid or minimize environmental impacts. 2. The location and installation of any required deck drains will be determined during final design stages. 3. The temporary, on-site detour bridge and approaches will be removed to pre-construction contour and revegetated with native tree species at 320 stems per acre. II. SUMMARY OF RECOMMENDATIONS Bridge No. 256 will be replaced in its existing location with a bridge. During construction traffic will be maintained with a temporary, on-site detour located west of the existing bridge. The estimated cost for the proposed improvement is $942,070. The estimated cost of the project, as shown in the NCDOT 1997-2003 Transportation Improvement Program, is $381,000 including $21,000 for right-of-way and $360,000 for construction. III. EXISTING CONDITIONS SR 1530/ SR 1948 is classified as a rural local route in the Statewide Functional Classification System. The proposed project occurs in a rural area along the Duplin County/Wayne County line approximately 12 kilometers (7.5 mi) east of the town of Mount Olive (Figure 1). Land use in the study area is primarily agricultural and silvicultural. Crop lands occupy uplands along the southern approach segment while woodlands are concentrated along steep upland slopes and within the inundated river floodplain. Near the bridge, SR 1530/ SR 1948 has a 6.1 meter (20 ft) pavement width with 2.4 meter (8 ft) shoulders. The roadway approaches slope down toward the bridge. The horizontal alignment is tangent on the bridge with a 1900 meter radius (1 degree) curve approximately 20 meters (65 ft) from the bridge to the south. The north approach is tangent. The roadway is situated approximately 4.3 meters (14 ft) above the creek bed. The traffic volumes were 900 vehicles per day (vpd) for 1995 and projected to be 2100 vpd for the design year 2020. The volumes include 1 % truck-tractor semi-trailer (TTST) and 2% dual-tired (DT) vehicles. The speed limit is not posted and assumed to be 88 kilometers per hour (55 mph). The existing bridge was built in 1955 (Figure 3). The superstructure consists of seven timber joist spans. Bridge deck construction is a creosote timber floor deck with an asphalt wearing surface. The substructure consists of creosote timber pile end bents and interior bents with timber caps. The overall length of the bridge is 36.9 meters (121 ft). Clear roadway width is 5.8 meters (19.2 ft). The posted weight limit is 7257.6 kilograms (8 tons) for single vehicles and 12,700.8 kilograms (14 tons) for tractor trailer trucks. Bridge No. 256 has a sufficiency rating of 9.5, compared to a rating of 100 for a new structure. Three accidents were reported in the vicinity of the bridge during the period from April 1, 1992 to March 31, 1995. There are no utilities located in the proposed project area. School buses do not use this bridge. IV. ALTERNATIVES No alternatives were considered for replacement of the bridge in its existing location. Utilizing the existing roadway provides the best alignment and the lowest cost. A relocated alignment would result in excessive cost and undesirable horizontal alignment. Based on a benefit-cost ratio of 2.7:1, an off- site detour is not reasonable (see Section VII). Temporary, on-site detours were considered west (Temporary Detour 1) and east (Temporary Detour 2) of the existing bridge. Traffic would be maintained with a temporary, on-site detour located west (Temporary Detour 1) of the existing bridge because this detour is less costly than Temporary Detour 2. The No-Build or "do-nothing" alternative was also considered but would eventually necessitate closure of the bridge. This is not desirable due to the traffic service provided by SR 1948/SR 1530. Investigation of the existing structure by the Bridge Maintenance Unit indicates that rehabilitation of the old bridge is not feasible due to its age and deteriorated condition. 2 V. ESTIMATED COST The estimated costs of the alternative studied, based on current prices, are as follow: Alternate A with on-site detour (Recommended) Alternate A with off-site detour Structure Removal $14,625.00 $14,625.00 Structure $263,900.00 $263,900.00 Roadway Approaches $163,282.50 $163,282.50 Miscellaneous and Mobilization $133,192.50 $133,192.50 Engineering and Contingencies $100,000.00 $100,000.00 Right-of-Way / Const. Easement / Util. $91950.00 $9,950.00 SUBTOTAL $684,950.00 $684,950.00 Temporary On-Site Detour No. 1 $257,120.00 NA TOTAL $942,070.00 $684,950.00 VI. RECOMMENDED IMPROVEMENTS Bridge No. 256 will be replaced in its existing location with a new structure approximately 41 meters (134 ft) in length having a clear roadway width of 9.2 meters (30 ft). Improvements to the existing approaches will be necessary on each end of the bridge. During construction traffic will be maintained with a temporary, on-site detour located west of the existing roadway (Temporary Detour 1). An off-site detour is not reasonable at this location due to its length of 12.6 kilometers (7.8 mi) of indirectional travel and the volume of traffic using SR 1530/SR 1948 (900 vpd in 1995 and 2100 vpd projected for 2020). The Division Office concurs with the recommended improvements. VII. TRAFFIC DETOUR A road user analysis was performed for detouring traffic on existing roads based on 900 vpd and an average of 12.6 kilometers (7.8 mi) of indirectional travel utilizing SR 1501, SR 1502, and SR 1754 (See Figure 1). The cost of additional travel would be approximately $760,000 during the twelye- month construction period. The estimated cost of providing an on-site detour is $277,120 resulting 3 in a benefit-cost ratio of 2.74:1. This ratio indicates justification to maintain traffic on-site during the construction period. VIII. NATURAL RESOURCES Materials and research data in support of this investigation have been derived from a number of sources including applicable U.S. Geological Survey (USGS) 7.5 minute quadrangle mapping (Williams, NC), U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory mapping, Natural Resources Conservation Service (formerly Soil Conservation Service) soils mapping (USDA 1959, USDA 1974), and 1993 aerial photography (scale: 1:1200) furnished by NCDOT. The principal investigator for natural resources was Kevin Markham with Environmental Services, Inc. Mr. Markham received his B.S. and M.S. degrees in Marine Biology from the University of North Carolina, Wilmington. He has eight years of experience in coastal ecosystems evaluations, wildlife surveys, wetland delineations, mitigation planning, and threatened and endangered species issues. The site was visited on March 14, 1996. Communities likely to be impacted by proposed improvements were walked and visually surveyed for important features. Surveys were conducted within a study corridor approximately 91.4 meters (300 ft) in width, symmetrical to the existing alignment. However, impact calculations are based on the approximate right-of-way and temporary construction easements. Special concerns evaluated in the field include potential habitat for protected species, wetlands, and water quality protection in upper reaches of the Northeast Cape Fear River. Plant community descriptions are based on a classification system utilized by the North Carolina Natural Heritage Program (NHP) (Schafale and Weakley 1990). When appropriate, community classifications were modified to better reflect field observations. Vascular plant names follow nomenclature found in Radford et al. (1968). Jurisdictional areas were identified using the three parameter approach (hydrophytic vegetation, hydric soils, wetland hydrology) following U.S. Army Corps of Engineers (COE) delineation guidelines (DOA 1987). Jurisdictional areas are characterized according to a classification scheme established by Cowardin et al. (1979). Habitats used by terrestrial wildlife and aquatic organisms, as well as expected population distributions, were determined through field observations, evaluation of available habitat, and supportive documentation (Martof et al. 1980; Webster et al. 1985; Menhinick 1991; Hamel 1992). Recreational fishing potential was obtained from Fish (1968). Water quality information for area streams and tributaries was derived from available sources (DEM 1989, DEM 1993). Quantitative sampling was not undertaken to support existing data. USFWS listings of federal protected species with ranges which extend into Duplin and Wayne Counties were obtained prior to initiation of the field investigation. In addition, NHP records documenting presence of federal or state listed species were consulted before commencing the field 4 investigation. r Physiography and Soils The bridge replacement project is located in the upper Coastal Plain physiographic province. This portion of the Coastal Plain is underlain by the Black Creek geologic formation, which is Cretaceous in age. The Black Creek formation is characterized by fine grained, micaceous sands containing intermittent glauconitic, fossiliferous clayey sand lenses (DNRCD 1985). Topography is characterized by broad, smooth flats and gently rolling interstream divides, periodically dissected by relatively slow-flowing streams and rivers. Elevations in the immediate project area range from 36 meters (118 ft) along the upland terrace to 30 meters (98 ft) within the river floodplain. The southern edge of the fowdplain, immediately adjacent to the river channel, supports a relatively steep rise onto the adjacent interstream divide while the northem floodplain area exhibits a broad gradual slope that constitutes an extensive riverine corridor. Soils in the study corridor include the Johnston series (Cumulic Humaquepts) and Pamlico series (Terric Medisaprists) in the river floodplain and the Ruston series (Typic Paleudults) in adjacent upland communities. The Johnston and Pamlico series are hydric, very poorly drained fluvial soils, with a seasonal high water table at or above the soil surface. These soils are flooded frequently and ' for long durations by overbank flood events from the adjacent river channel. The non-hydric, Ruston map unit supports well drained soils on a convex slope adjacent to the riverine floodplain. These upland soils exhibit moderate permeability, low shrink-swell potential, and have a seasonal high water table below 1.5 meters (5 ft) of the surface. WATER RESOURCES Waters Impacted The study corridor is located within the Northeast Cape Fear River Subbasin (USGS hydrologic unit 03030007) of the Cape Fear River Basin. Bridge No.256 crosses upper reaches of Northeast Cape Fear River near the town of Mount Olive approximately 12 kilometers (7.5 mi) downstream of the origin of this blackwater system. This below-headwater tributary flows southeast from the study corridor approximately 145 kilometers (90 mi) to the confluence with the Cape Fear River and Brunswick River near Wilmington, N.C. The Northeast Cape Fear River in the study corridor region has been assigned Stream Index Number 18-31-(23) by the N.C. Division of Environmental Management (DEM). tsest usage ijassmcatlons ana water wain Classifications are assigned to waters of the State of North Carolina based on the existing or contemplated best usage of various streams or segments of streams in the basin. The upper Northeast Cape Fear River segment has a best use classification of C Sw (DEM 1993). The designation C denotes that the appropriate uses include aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. Secondary recreation refers to human body contact on an infrequent or incidental basis. The Sw designation is used for swamp waters characterized by low velocities, low pH, low dissolved oxygen levels, and high organic content. The proposed project will not impact any High Quality Waters (HQW), Outstanding Resource Waters (ORW), or Water Supply (WS-I, WS-II) waters (DEM 1993). In addition, none of these classifications occur within 1.6 kilometers (1 mi) of the project area. The Northeast Cape Fear River is not designated as a North Carolina Natural and Scenic River, nor is it designated as a national Wild and Scenic River. There are no point source dischargers with a permitted flow over 0.5 mgd located in the project area (DEM 1989). The nearest permitted discharge comprises the Mount Olive Waste Water Treatment Plant, with a permitted discharge of 1.0 mgd, located approximately 12 kilometers (7.5 mi) upstream of the project bridge. Point source dischargers will not be affected by proposed improvements. The Benthic Macroinvertebrate Ambient Network (BMAN) addresses long-term trends in water quality at fixed monitoring sites by the sampling for selected benthic macroinvertebrates (DEM 1989). Species richness and overall biomass are considered to be reflections of water quality. Two BMAN special study sites are located in the project vicinity, as a result of a study of Mount Olive Pickle. DEM sampling site No.61 is located at NC 403 on the Northeast Cape Fear River, approximately 5.6 kilometers (3.5 mi) upstream from the study corridor. In addition, the Polly Run Creek sampling station (DEM Site No.60) is located on a tributary which confluences with the Northeast Cape Fear River approximately 2.4 kilometers (1.5 mi) upstream from the study corridor. Polly Run Creek exhibits a good/fair bioclassification rating while assessments at NC 403 indicate a poor bioclassification rating. Brine wastes appear to have resulted in poor water quality within the portion of the upper Northeast Cape Fear River which includes the study corridor (DEM 1989). Stream Characteristics This blackwater system supports a broad, meandering stream channel measuring approximately 7.6 meters (25 ft) in bank-full width in the bridge vicinity. Depth of stream water averages approximately 1.8 meters (6 ft) at bank-full discharge. Stream flow is slow to very slow with the substrate and stream banks composed primarily of sand and silt deposits. Submergent, aquatic vegetation and accumulations of organic debris are evident along the upper portions of subject stream banks. Anticipated Impacts to Water Resources Short-term impacts to water quality, such as sedimentation and turbidity, can be anticipated from construction-related activities. Adverse impacts will be minimized by implementing the NCDOT Bgq Management Practices for Protection of Surface Waters (BMPs), as applicable, during construction. No adverse long-term impacts to water resources are expected to result from proposed improvements. The proposed bridge replacement will allow for continuation of present flow rates thereby protecting stream integrity. 6 BIOTIC RESOURCES Four distinct communities were identified within the study corridor. Two communities, identified as mixed mesophytic hardwood forest and riverine swamp forest, are considered natural communities. The other two communities, identified as agricultural land and upland urban/disturbed land, result from some level of disturbance. The plant communities are described below. Riverine Swamp Forest The river floodplain supports a wetland, swamp forest community dominated by bald cypress (Taxodium distichum), swamp tupelo (Nyssa biflora), water tupelo (Nyssa aquatica), sweet gum (Liquidambar styracif lua), and river birch (Betula nigra). Understory/shrub development is sparse and includes regeneration of canopy species along with Carolina ash (Fraxinus caroliniana), sweet bay (Magnolia virginiana), red bay (Persea palustris), and dog hobble (Leucothoe axillaris). Groundcover is also sparse, usually concentrated upon hammocks, and includes arrowhead (Sagittaria sp.), lizard's tail (Saururus cernuus), sphagnum mosses (Sphagnum spp.), royal fern (Osmunda regalis), netted chain-fern (Woodwardia areolata), and Virginia chain-fern (Woodwardia virginiana). Mixed Mesophytic Hardwood Forest Relatively steep riparian slopes bordering the southern edge of the river floodplain support mesic hardwood forest cover. This upland community is dominated by sweet gum, red maple (Acer rubrum), willow oak (Qum w phellos), northern red oak (Quercus rubra), and white oak (Quercus alba). The understory/shrub layer is generally characterized by sapling growth of canopy species along with privet (Ligustrum sinense), red mulberry (Morus rubra), and black cherry (Prunus serotina). Characteristic vines include trumpet creeper (Campsis radicans), Japanese honeysuckle (Lonicera japonica), poison ivy (Toxicodendron radicans), and blackberry (Rubus sp.). Agricultural Land The upland terrace along the southern study corridor boundary supports agricultural land currently under crop rotation. This area typically supports crops such as corn and tobacco with disturbance- adapted, successional plant species inhabiting field edges and ditch banks. Upland Urban/Disturbed Land This community classification includes disturbed roadside margins and maintained grass right-of- ways. Along roadside fringes, maintained grasses and early successional herbs persist on eroded slopes and among scattered household debris. Anticipated impacts to plant communities are estimated based on the amount of each plant community present within the proposed right-of-way and temporary construction easements. A summary of plant 7 community impacts which could result from construction activities is presented below. Table 1. Estimated plant community impacts. PLANT COMMUNITY ESTIMATED IMPACT in hectares (acres in parentheses) Alternative A Temp. Detour .1 Temp. Detour 2 Riverine Swamp Forest Mesophytic Hardwood Forest Agricultural Land Urban/Disturbed Land 0.32 (0.79) 0.01 (0.02) 0.00 (0.00) 0.26 (0.65) 0.25 (0.61) 0.03 (0.07) 0.00 (0.00) 0.00 (0.00) 0.22 (0.54) 0.05 (0.12) 0.05 (0.12) 0.08 (0.21) TOTAL: 0.59(l.46) 0.28 (0.68) 0.40 (0.99) Impacts to plant communities as a result of Alternative A will total approximately 0.59 hectare (1.46 ac). These impacts are restricted to narrow strips immediately adjacent to the existing bridge and roadway approach segments. Nearly one-half of these potential impacts 0.26 hectare (0.65 ac) do not infringe upon natural communities, but affect agricultural and disturbed lands. The off site detour alternative is not expected to result in impacts to plant communities due to the utilization of existing roads. Temporary on-site detour alternatives exhibit a minor variation in impacts to natural communities. Temporary Detour 1 will impact approximately 0.28 hectare (0.68 ac) of natural communities while Temporary Detour 2 will impact approximately 0.27 hectare (0.66 ac) of natural communities. Impacts to plant communities as a result of either detour alternative are temporary. Upon completion of the bridge replacement project, fill associated with the temporary detour will be removed and the area will be restored. Construction of the proposed alternative and temporary detour is not expected to result in substantial adverse impacts to the plant communities in the study corridor. Temporary detour fill will be removed after construction allowing for restoration at these impacted areas. Wildlife Most of the study corridor outside the river floodplain consists of agricultural land. Clearing and conversion of large tracts of land has eliminated contiguous cover and limited travel opportunities for many traditional forms of wildlife. Even so, remaining contiguous natural communities concentrated within the Northeast Cape Fear River floodplain represent valuable habitat for resident species. Forested floodplains and adjacent mesophytic slopes provide the necessary components (food, water, protective covering) for mammals, raptors, and songbirds. I Sightings or evidence (tracks, scat, burrows, etc) were noted for several species of mammals including white-tailed deer (Odocoileus virginianus), raccoon (Procyon lotor), mink (Mustela vison), marsh rabbit (Sylvilagus palustris), and bobcat (Felix mfus). Tree cuttings and embankment burrows indicate the presence of beaver (Castor canadensis) and muskrat (Ondatra zibethicus). Raptors and owls expected in the river floodplain and adjacent areas include red-tailed hawk (Buteo jamaicensis), red-shouldered hawk (Buteo lineatus), barred owl (Strix varia), great homed owl (Bubo virginianus), and eastern screech owl (Otus asio). Raptors and owls may nest in the mature bottomland swamp forests and feed along adjacent agricultural fields. Waterbirds which frequent swamp bottomlands and can be expected in the study area include great blue heron (Ardea herodias), belted kingfisher (Ceryle alcyon), wood duck (Aix sponsa), mallard (Anas platyrhynchos), and green-backed heron (Butorides striatus). Aquatic L This section of the Northeast Cape Fear River may contain limited recreational fisheries for redfin pickerel (Esox americanus) and warmouth (Lepomis gulosus) (Fish 1968). Additional nongame fish populations expected to inhabit the stream/river system include pirate perch (Aphredoderus sayanus), eastern mud minnow (Umbra pygmaea), and mud sunfish (Acantharchus pomotis). However, documented pollution (brine) sources upstream of the project bridge may have limited habitat suitability for freshwater mussel species (Elliptio spp.). Stream bank surveys uncovered no shell fragments which could indicate mussel presence at the bridge site. Semi-permanently inundated back-water areas and ephemeral pools in the floodplain provide suitable habitat for a wide array of semi-aquatic organisms such as eastern newt (Notophthalmus viridescens), southern dusky salamander (Desmognathus auriculatus), several frog species (Rana spp.), painted turtle (Chrysemys picta), and banded water snake (Nerodia fasciata). Anticipated Impacts to Wildlife Due to the limited extent of infringement on natural communities, the proposed bridge replacement will not result in substantial loss or displacement of known terrestrial or aquatic animal populations. Maintenance of regular flow and stream integrity will minimise potential down-stream impacts to aquatic habitat by the proposed bridge replacement. In addition, permanent and temporary impacts to downstream aquatic habitat from increased sediment during construction will be minimized by the implementation of the NCDOT Best Management Practices for Protection of Surface Waters. SPECIAL TOPICS Waters of the United States Surface waters within the embankments of the Northeast Cape Fear River are subject to consideration 9 under Section 404 as "waters of the United States" (33 CFR 328.3). Due to the frequent and prolonged overflow of the river into the swamp system, this surface water area has been included within the riverine swamp forest plant community acreage. Wetlands subject to review under Section 404 of the Clean Water Act (33 U.S.C. 1344) are defined by the presence of three primary criteria: hydric soils, hydrophytic vegetation, and evidence of hydrology at or near the soil surface for a portion (12.5 percent) of the growing season (DOA 1987) Based on this three parameter approach, one jurisdictional wetland type occurs within the broad floodplain associated with the Northeast Cape Fear River. The riverine swamp forest plant community exhibits characteristics of palustrine forested, deciduous, semi-permanently flooded wetlands (PF06F). The following table summarizes potential wetland impacts which could result from the in-place bridge replacement and temporary detours. Table 2. Estimated wetland impacts. WETLAND TYPE ESTIMATED IMPACT in hectares (acres in parentheses) Alternative A Temp. Detour 1 Temp. Detour 2 PF06F 0.32 (0.79) 0.25 (0.61) 0.22 (0.54) Bridging of the Northeast Cape Fear River will minimise impacts to the open waters of the river. Impacts to wetlands as a result of Alternative A will total 0.32 hectare (0.79 ac). These impacts are restricted to narrow strips immediately adjacent to the existing bridge and roadway approach segments. Temporary detour alternatives would each impact nearly the same amount of wetlands, but Temporary Detour 1 will impact approximately 0.03 hectare (0.07 ac) more than Temporary Detour 2. Impacts to wetlands as a result of either detour alternative are temporary. Upon completion of the bridge replacement, fill associated with the temporary detour will be removed and the area will be restored. Impacts to jurisdictional wetlands are anticipated from project construction. In accordance with provisions of Section 404 of the CWA, a permit will be required from the COE for the discharge of dredge or fill material into "Waters of the United States." A Nationwide Permit 33 CFR 330.5 (A) (23) is likely to be applicable for all impacts to Waters of the United States from the proposed project. This permit authorizes activities undertaken, assisted, 10 L t r? IX. CULTURAL RESOURCES This project is subject to compliance with Section 106 of the National Historic Preservation Act of 1966, as amended, implemented by the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. Section 106 requires that for federally funded, licensed, or permitted projects, having an effect on properties listed in or eligible for the National Register of Historic Places, the Advisory Council on Historic Preservation be given an opportunity to comment. In a concurrence form dated May 9, 1996 the Federal Highway Administration, NCDOT, and the North Carolina State Historic Preservation Office (SHPO) concurred that there are no properties, including Bridge No.256, in the area of potential effect (APE) listed in or eligible for the National Register (see Appendix for Concurrence Form). In their April 22, 1996 letter, the SHPO stated there are no known archaeological sites in the proposed project area and it is unlikely that any archaeological resources which may be eligible for the National Register of Historic Places will be affected. They recommended no archaeological investigation be conducted in connection with this project (see Appendix for SHPO letter). Therefore, the NCDOT has not conducted nor will conduct any archaeological work in connection with this project. Since there are no properties either listed in or eligible for the National Register of Historic Places within the APE, no further compliance with Section 106 is required. X. ENVIRONMENTAL EFFECTS The project is expected to have an overall positive impact by replacing a potentially unsafe bridge. Inconvenience to motorists will be negligible since traffic will be maintained on site. The project is considered a Federal "Categorical Exclusion" due to its limited scope and insignificant environmental consequences. The bridge replacement will not have an adverse effect on the quality of the human or natural environment with the use of current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulations. No significant change in existing land use is expected to result from replacement of the bridge. No adverse impact on families or communities is anticipated. No relocatees are expected with implementation of the proposed alternative. No adverse effect on public facilities or services is anticipated. The project is not expected to adversely affect social, economic, or religious opportunities in the area. 13 There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. Since the project will consist of replacing an existing bridge in its existing location, the Farmland Protection Policy Act does not apply. This project is an air quality "neutral" project, so it is not required to be included in the regional emissions analysis and a project level CO analysis is not required. Noise levels could increase during demolition but will be temporary. If vegetation is disposed of by burning, all burning shall be done in accordance with applicable local laws and regulations of the North Carolina State Implementation Plan (SIP) for air quality in compliance with 15 NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic noise of Title 23, Code of Federal Regulations (CFR), Part 772 and for air quality (1990 Clean Air Act Amendments and the National Environmental Policy Act) and no additional reports are required. An examination of records at the North Carolina Department of Environment, Health and Natural Resources, Division of Environmental Management, Groundwater Section and the North Carolina Department of Human Resources, Solid Waste Management Section revealed no underground storage tanks or hazardous waste sites in the project area. Duplin and Wayne Counties are participants in the National Flood Insurance Regular Program. The bridge is located in a Detailed Study Area. The Flood Boundary and Floodway Map is included in the Appendix. This map indicates the limits of the 100-year and the 500-year floodplains as well as the 100-year floodway. Since the proposed bridge will be an in-kind replacement, it is not anticipated that this project will have a significant adverse impact on the existing floodplain and floodway nor on the associated flood hazard to the adjacent properties and buildings. On the basis of the above discussion, it is concluded that no significant adverse environmental effects will result from implementation of the project. 14 REFERENCES Cowardin, L.M., V. Carter, F.C.

Crow, Dire Thank you for your letter of March 13, 1996, concerning the above project. We are aware of no structures of historic or architectural importance within the general area of the project. We recommend that an architectural historian on your staff identify and evaluate any structures over fifty years of age within the project area, and report the findings to us. There are no known archaeological sites within the proposed project area. Based on our present knowledge of the area, it is unlikely that any archaeological resources which may be eligible for inclusion in the National Register of Historic Places will be affected by the project construction. We, therefore, recommend that no archaeological investigation be conducted in connection with this project. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800. Thank you for your cooperation and consideration. If you have questions concerning the above comment, please contact Renee Gledhill-Earley, environmental review coordinator, at 919/733-4763.

DEM requests that DOT strictly adhere to North Carolina regulations entitled, "Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) throughout design and construction for this project in the area that drains to streams having WS (water supply), ORW (outstanding resource water), HOW (high quality water), B (body contact), SA (shellfish water) or Tr (trout water) classifications to protect existing uses. B. DEM requests that bridges be replaced in existing location with road closure. If an on-site detour or road realignment is necessary, the approach fills should be removed to pre-construction contour and revegetated with native tree species at 320 stems per acre. C. DEM requests that weep holes not be installed in the replacement bridges in order to prevent sediment and other pollutants from entering the body of water. If this is not completely possible, weep holes should not be installed directly over water. D. Wetland impacts should be avoided (including sediment and erosion control structures/measures). If this is not possible, alternatives that minimize wetland impacts should be chosen. Mitigation for unavoidable impacts may be required. E. Borrow/waste areas should avoid wetlands. It is likely that compensatory mitigation will be required if wetlands are impacted by waste or borrow. Please be aware that 401 Certification may be denied if wetland or water impacts have not been avoided and minimized to the maximum extent practicable. cc: Monica Swihart Melba McGee bridges.sco P.O.

Oar `,\;; LNG & Reference your letter dated March 13, 1996, requesting comments regarding the potential environmental impacts associated with the North Carolina Department of Transportation (NCDOT) Group XI Bridge Replacement Project, Bridge No. 50 on NC Highway 903 over Little Contentnea Creek, at the Pitt County and Greene County line, near Scuffleton, North Carolina, TIP 3-1204. Section 404 of the Clean Water Act regulates excavation and/or discharge of excavated and/or fill material into waters of the United states, including wetlands. The Corps of Engineers must assess the impacts of such activities on the aquatic environment before a final permit decision can be made. ' Federal permit authorization of fill activities within waters of the United States pursuant to Section 404 requires that the project be water dependant and/or that no practicable alternatives are available. Our initial emphasis for review of NCDOT projects focuses on anticipated impacts to waters and/or wetlands. However, if degradation to other aspects of the natural environment (e.g., critical habitat of endangered species) is considered to be of greater concern, an alternative resulting in greater aquatic losses may be ' chosen as preferred. In all cases, and in accordance with the 1990 Mitigation Memorandum of Agreement between the U.S. Environmental Protection Agency and the Corps, unavoidable impacts to wetland resources must be addressed prior to the final permit decision. Based upon our review of the documentation you provided, much more information is needed for us to make a determination rrmarHinca rha Federal permit requirements. Specifically, you should provide project plans which describe the proposed work and indicate all impacts to waters of the United States, including wetlands, associated with this project. Wetland impacts should be described in terms of size, location, and type. This includes temporary and permanent approach fills, and any borrow/waste activity that may impact waters and/or wetlands. ' Once this information becomes available, please provide it to the Washington Regulatory Field office for our review. As your planning process continues, please be reminded that avoidance and minimization of impacts to ' waters and wetlands should be undertaken to the maximum extent practicable. In addition, a compensatory mitigation plan must be developed and approved prior to the issuance of a Department of the Army permit. -2- Thank you for your time and cooperation.

This report provides scoping information and is provided in accordance with provisions of the Fish and Wildlife Coordination Act (16 U.S.C. 661-667d) and Section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543). This report also serves as comments to federal and state resource agencies for use in their permitting and/or certification processes for this project. Preliminary planning by the North Carolina Department of Transportation (NCDOT) calls for the replacement of fourteen bridges in various Eastern North Carolina counties. The Service's mission is to provide the leadership to conserve, protect, and ' enhance fish and wildlife and their habitats for the continuing benefit of all people. Due to staffing limitations, we are unable to provide you with site- specific comments at this time. However, the following recommendations should help guide the planning process and facilitate our review of the project. Generally, the Service recommends that wetland impacts be avoided and minimized to the maximum extent practicaoie as outlined in the Clean water Act Section 404(b)(1) Guidelines. Bridge replacements should maintain natural water flows and circulation regimes without scouring or impeding fish and wildlife passage. Habitat fragmentation should be minimized by using the existing disturbed corridor instead of a new alignment. Impact areas should be stabilized by using appropriate erosion control devices and/or techniques. Wherever appropriate, construction in sensitive areas should occur outside of anadromous fish spawning and migratory bird nesting seasons. We reserve the right to review any required federal or state permits at the time of public notice issuance. Resource agency coordination should occur early in the planning process to resolve land use conflicts and minimize delays. In addition to the above guidance, we recommend that the environmental documentation for this project include the following (the level of detail should be commensurate with the degree of environmental impacts): 1. A clearly defined purpose and need for the proposed project including a discussion of the project's independent utility; 2. An analysis of the alternatives to the proposed project that were considered, including a no action alternative; 3. A description of the fishery and wildlife resources within the action area of the proposed project which may be affected directly or indirectly; 4. The extent and acreage of waters of the U.S., including wetlands, that are to be impacted by filling, dredging, clearing, ditching, and/or draining. Wetland impact acreages should be differentiated by habitat type based on the wetland classification scheme of the National Wetlands Inventory. Wetland boundaries should be determined by using the 1987 Corps of Engineers Wetlands Delineation Manual and verified by the U.S. Army Corps of Engineers; 5. The anticipated environmental impacts, both temporary and permanent, that would be likely to occur as a direct result of the proposed project. Also, an assessment should be included regarding the extent to which the proposed project would result in secondary impacts to natural resources and how this and similar projects contribute to cumulative adverse effects; 6. Techniques which would be employed to design and construct wetland crossings, relocate stream channels, and restore, enhance, or create wetlands for compensatory mitigation; 7. Mitigation measures which would be employed to avoid, minimize, rectify, reduce, or compensate for habitat value losses associated with the project. These measures should include a detailed compensatory mitigation plan for offsetting unavoidable wetland impacts. The attached page identifies the Federally-listed endangered, threatened, and candidate species that are known to occur in Bladen, Brunswick, Columbus, Cumberland, Duplin, Durham, Greene, Pender, Pitt, Robeson, Scotland, Wayne, and Wilson counties. Habitat requirements for the Federally-listed species in the project area should be compared with the available habitat at the project site. If suitable habitat is present within the action area of the project, field surveys for the species should be performed, and survey methodologies and results included in the environmental documentation for this project. In addition to this guidance, the following information should be included in the environmental document regarding protected species (the level of detail should be commensurate with the degree of environmental impacts): 1. A specific description of the proposed action to be considered; 2. A description and accompanvinq map of the specific area used in the analysis of direct, indirect, and cumulative impacts; 3. A description of the biology and status of the listed species and of the associated habitat that may be affected by the action, including the results of an onsite inspection; 4. An analysis of the "effects of the action" on the listed species and associated habitat: a. Direct and indirect impacts of the project on listed species. Indirect effects are those that are caused by the proposed action and are later in time but are still reasonably certain to occur; b. A discussion of the environmental baseline which includes interrelated, interdependent, past and present impacts of Federal, State, and private activities in the project and cumulative effects area; 1 c. Interrelated actions are those that are part of a larger action and depend on the larger action for their justification; d. Cumulative impacts of future State and private activities (not requiring Federal agency involvement, that will be considered as part of future Section 7 consultation); ' 5. Summary of evaluation criteria used as a measurement of potential effects; 6. A description of the manner in which the action may affect any listed species or associated habitat including project proposals to reduce/eliminate adverse effects; 7. Based on evaluation criteria, a determination of whether the project is not likely to adversely affect or may affect threatened and endangered species. Candidate species are those plant and animal species for which the Service has sufficient information on their biological status and threats to their survival to propose them as endangered or threatened under the Endangered Species Act (ESA). Although candidate species receive no statutory protection under the ESA, Federal agencies are required to informally confer with the Service on actions ' likely to jeopardize the continued existence of these species or that may destroy or modify proposed critical habitat. Species of concern include those species for which the Service does not have enough scientific information to support a listing proposal or species which do not warrant listing at the present time. Species of Concern receive no statutory protection under the ESA, but could ' become candidates in the future if additional scientific information becomes available indicating they are endangered or threatened. Formal listing places the species under the full protection of the ESA, and necessitates a new survey if its status in the project corridor is unknown. Therefore, it would be prudent for the project to avoid any adverse impact to candidate species or their habitat. The North Carolina Natural Heritage Program should be contacted for information on species under State protection. The Service appreciates the opportunity to comment on this project. Please continue to advise us of the progress made in the planning process, including your official determination of the impacts of this project. 1 Attachments ' cc: NCDEHNR-DEM NCWRC NMFS FHWA ' USACE EPA 1 FWS/R4/KDoak/KHD:3-26-96/919-856-4520 ext 19/wp:BMAR96.SCP US Department of Transportation UnftW Stc?s Coast Guard Commander Fifth Coast Guard Diatriot Federal Building 431 Crawford Street Portsmouth, VA 237 .5044 Staff Symbol: Owb ) Phone: (804) 198-622 16590 20 Aug 96 Mr. H.

Box 25201 Raleigh, North Carolina 27611-5201 Dear Mr. Vick: This responds to your letters of 5une 13, 1996, requesting our concurrence that Coast Guard Bridge Permits will not be required for the proposed replacements of Bridge No. 256 over the Northeast Cape Fear River, Bridge No. 1 over Sturgeon Creek, and Bridges No. 16 and 103 over the number River. Section 107 of the Coast Guard Authorization Act of 1982, Publio Law 97-322, exempts bridge projects from Coast Guard Bridge Permits when the bridge project crosses nontidal waters which are not used, susceptible to use in their natural condition, or susceptible to use by reasonable improvement as a means to transport interstate or foreign commerce. We have determined that each of these bridge projects will cross a section of waterway which meets these conditions. Accordingly, Coast Guard Bridge permits will not be required for any of these bridges. The fact that Coast Guard Bridge Permits will not he required for these projects does not receive you of the responsibility for compliance with the requirements of any other Federal, State or local agency who may have jurisdiction by law over any other aapect of the projects.
