Box 1890 Wilmington, North Carolina 28402-1890 ATTENTION: Mr. David Timpy NCDOT Coordinator Dear Sir: IT Le-- Subject: Robeson County, Replacement of Bridge No. 58 over Waft Swamp on NC 71, Federal Project No. BRSTP-71(2), State Project No. 8.1462701, T.I.P. No. B-3029. AID No. 199701747. Please find enclosed three copies of the project planning report for the above referenced project. Bridge No. 58 will be replaced on existing alignment with a new bridge approximately 37 meters (120 feet) in length and 9.6 meters (32 feet) wide. During construction traffic will be maintained on a temporary detour bridge located on the north side of the bridge. Jurisdictional wetland impacts described in the attached Categorical Exclusion document were based on the entire right-of-way width. We have recently delineated the wetlands at the site and the revised impacts are 0.38 acres of permanent impact consisting of 0.052 acres of fill in wetlands and 0.33 acres of mechanized clearing. In addition, there will be 0.88 acres of temporary impacts from the temporary detour. At the request of the North Carolina Wildlife Resources Commission (WRC), there will be a moratorium of instream work from April 1 and June 15 to avoid interfering with fish reproduction. DAVID MCCOY SECRETARY APR ?? 4 2000 ?a, M'EfI-ANDS71 ;. A QUnL11Y )N The project is being processed by the Federal Highway Administration as a "Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, we do not anticipate requesting an individual permit, but propose to proceed under Nationwide Permit 23 in accordance with the Federal Register of December 13, 1996, Part VII, Volume 61, Number 241. This project contains a bridge removal over Waters of the U.S. The superstructure consists of reinforced concrete deck and railings on timber joists. The substructure consists of timber caps on timber piles. The bridge rails and substructure will be removed without dropping them into Waters of the U.S. There is potential for components of the deck to be dropped into the Waters of the U.S. during construction. The resulting temporary fill associated with the concrete deck is approximately 44 cubic yards. We anticipate a 401 General Certification will apply to this project, and are providing one copy of the CE document to the North Carolina Department of Environment, and Natural Resources, Division of Water Quality, for their review.

No. B-3029 Bridge No. 58 is included in the North Carolina Department of Transportation (NCDOT) 1998- 2004 Transportation Improvement Program. The location is shown in Figure 1. No substantial impacts are anticipated as a result of this action. The project is classed as a Federal "Categorical Exclusion." 1. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures, including NCDOT's Best Management Practices for Protection of Surface Waters, and Stream Crossing Guidlines for Anadromous Fish Passage will be implemented, as applicable, to avoid or minimize environmental impacts. 2. Construction of the project will take place in such a manor as to avoid instream activities between April 1 and June 15 to avoid interfering with fish reproduction. 3. The approach fill for the on-site detour will be removed to pre-construction contour and revegetated with native vegetation. If undercutting is necessary for the on-site detour the material will be stockpiled to be used to restore the site. 4. Borrow / waste areas will not be located in wetlands. Compensatory mitigation will be required if wetlands are impacted by waste or borrow. II. SUMMARY OF RECOMMENDATIONS Bridge No. 58 will be replaced on existing alignment as shown in Figure 2. It will be replaced with a new bridge approximately 37 meters (120 ft) in length, with a clear roadway width of 9.6 meters (32 ft). The grade of the new structure will be approximately the same as the existing bridge grade at this location. The proposed approach roadway will have a 7.2 meter (24 ft) travelway with 2.4 meter (8 ft) shoulders including 1.2 meter (4 ft) paved. When guardrail is warrented, the shoulder width will be 3.4 meters (11 ft.) The approach work will extend approximately 143 meters (430 ft) northeast and southwest of the bridge. During construction, traffic will be maintained by a temporary detour bridge located on the north side of the existing bridge. The estimated cost, based on current prices, is $870,600 including $20,600 for right-of-way and $850,000 for construction. The estimated cost of the project, as shown in the NCDOT 1998- 2004 Transportation Improvement Program, is $430,000 including $30,000 for right-of-way and $400,000 for construction. III. EXISTING CONDITIONS NC 71 is classified as a rural major collector route in the Statewide Functional Classification System. Land use is primarily wooded areas and swamp in the immediate vicinity of the bridge. Big Raft Swamp dominates the area immediately adjacent to the roadway and extends approximately 152 meters (500 ft) to the southwest and approximately 305 meters (1000 ft) to the northeast of Bridge No. 58. The approach to the existing bridge is tangent on both sides. The roadway at the bridge is approximately 3.7 meters (12 ft) above the creek bed. The speed limit is posted as 90 km/h (55 mph) at the project site. The projected traffic volume for the bridge is 6,000 vehicles per day (vpd) for 1998 and 9,100 vpd for the design year 2018. The proposed bridge replacement project is based on design traffic volumes of eight percent truck-tractor semi-trailer (TTST), two percent dual-tired vehicles (DT), ten percent design hourly volume and sixty percent directional. The existing bridge was built in 1931 (Figure concrete deck with an asphalt wearing surface piles with cross bracing at interior bents. 3). The superstructure consists of reinforced The substructure consists of timber caps and The overall length of the bridge is 31.7 meters (104 ft). The clear roadway width is 8.6 meters (28.3 ft). The posted weight limit is 29,030 kilograms (32 tons) for single vehicles and truck- tractor semi-trailers. Bridge No. 58 has a sufficiency rating of 41.5, compared to a rating of 100 for a new structure. Five accidents were reported on NC 71 near Bridge No. 58 during the period from July 1, 1993 to June 30, 1996. Three accidents involved vehicles running off the road under normal road conditions. Two accidents involved vehicles colliding with stationary objects in the travelway. Two of the five accidents were double-vehicle accidents. Aerial phone lines and cable television lines exist along the south side of NC 71. Utility impacts are anticipated to be low. A total of 8 school buses cross this bridge twice daily. IV. ALTERNATIVES The bridge alternatives studied for replacing Bridge No. 58 included a new bridge approximately 37 meters (120 ft) in length that would accommodate a 7.2 meter (24 ft) travelway with 1.2 meter (4 ft) shoulders on each side. The approach roadway would consist of a 7.2 meter (24 ft) travelway with 2.4 meter (8 ft) shoulders, including 1.2 meters (4 ft) paved. Alternate A (Recommended): Replace Bridge No. 58 on existing alignment with a temporary on-site detour bridge on the north side. The roadway grade of the new structure will be approximately the same as the grade on the existing bridge. The approach work will extend approximately 143 meters (470 ft) northeast and southwest of the proposed bridge. The detour bridge will be approximately 29 meters (95 ft) in length. Alternate B: Replace Bridge No. 58 on new alignment north of the existing bridge. Traffic will be maintained on the existing bridge during construction. The approach work will extend approximately 182 meters (600 ft) southwest and northeast of the proposed bridge. Alternate C: Replace Bridge No. 58 with a new bridge at the existing location. Traffic will be detoured off-site along existing roads during construction. The roadway grade of the new structure will be approximately the same as the grade on the existing bridge. The approach work will extend approximately 96 meters (325 ft) northeast and southwest of the proposed bridge. Other Alternates: The "do-nothing" alternative would eventually necessitate closure of the bridge. This is not desirable due to the traffic service provided by NC 71. Investigation of the existing structure by the Bridge Maintenance Unit indicates the rehabilitation of the old bridge is not feasible due to its age and deteriorated condition. V. ESTIMATED COST The estimated costs of the alternates studied, based on current prices, are as follows: (Recommended) Alternate A Structure Removal (existing) $ 20,400 Structure (proposed) 228,000 Temp. Detour Structure and Approaches 225,000 Roadway Approaches 84,600 Miscellaneous and Mobilization 181,000 Engineering and Contingencies 111,000 Alternate B $ 20,400 228,000 N/A 467,600 241,000 143,000 27,000 Alternate C $ 20,400 228,000 N/A 84,600 102,000 65,000 18,950 ROW/Const. Easements/Utilities 20,600 TOTAL $ 870,600 VI. $1,127,000 $ 518,950 Bridge No. 58 will be replaced on the existing alignment at approximately the same elevation with a length of 37 meters (120 ft). Traffic will be maintained by an on-site detour upstream of the bridge (Alternate A) due to the following: The off-site detour route (See Fig. 1) is approximately 6.2 miles in length with a roaduser cost of approximately $2,700,000 for a nine month road closure period. The proposed route crosses Bridges No. 36 and 37 which have a weight limit of 22 tons and 20 tons. Bridge No. 58 has a weight limit of 32 tons. Therefore, the studied detour is not a suitable alternative. • The ADT of 6000 vpd and the truck traffic generated by the Campbell Soup Company. • Utilities are located downstream of the existing bridge. An on-site detour downstream will require utilities to be relocated and create additional impacts to the wetlands. • The on-site detour alternative has less permanent impact to the wetlands and the cypress gum swamp, than the new alignment altemative. A 9.6 meter (32 ft) clear roadway width is recommended on the replacement structure in accordance with the current NCDOT Bridge Policy. This will provide a 7.2 meter (24 ft) travelway with 1.2 meter (4 ft) shoulders across the structure. A 7.2 meter (24 ft) travelway with 2.4 meter (8 ft) shoulders, including 1.2 meters (4 ft) paved, will be provided on the proposed approaches. Where guardrail is warrented a 3.4 meter (11 ft.) shoulder will be used. The Division Engineer concurs in the recommendation that the structure be replaced on the existing alignment utilizing an on-site detour. Based on a preliminary hydraulic analysis utilizing the 25 year design storm, the new structure is recommended to have a length of approximately 37 meters (120 ft). The elevation of the new structure will be approximately the same as the existing bridge. The replacement structure will maintain a minimum 0.3% grade to facilitate deck drainage. The length and height may be increased or decreased as necessary to accommodate peak flows as determined by further hydrologic studies. VII. NATURAL RESOURCES The proposed project study area lies within the Coastal Plain Physiographic Province in rural Robeson County, approximately 5.5 kilometers (3.5 miles) northeast of Red Springs, North Carolina (Figure 1). Methodology Informational sources used to prepare this report include: U.S. Geological Survey (USGS) Red Springs quadrangle map (1974); Soil Conservation Service (SCS) Soil Survey of Robeson County (1978); United States Fish and Wildlife Service (USFWS) National Wetlands Inventory Map (Red Springs 1995); USFWS list of protected species and federal species of concern (1997); North Carolina Natural Heritage Program (NCNHP) database of rare species and unique habitats (1996); NCDOT aerial photography of the project area (1:1200); North Carolina Division of Environmental Management (NCDEM) water resource data; and North Carolina Wildlife Resources Commission (NCWRC) proposed critical habitat information. Research using these resources was conducted prior to the field investigation. A general field survey was conducted along the proposed project corridor on October 21, 1996. Plant communities and their associated wildlife were identified using a variety of observation techniques, including active searching, visual observations with binoculars, and identifying characteristic signs of wildlife (sounds, tracks, scat, and burrows). Quantitative impact calculations were based on.the worst case scenario using the full 30.4 meter (100.0 foot) wide right-of-way limits, the width of the stream for aquatic impacts, and the length of the project approaches. The actual construction impacts will be less, but without specific replacement structure design information (pier intrusions, etc.) the worst case was assumed for the impact calculations. Definitions for area descriptions used in this report are as follows: "project study area", "project area", and "project corridor" denote the speck area being directly impacted by each alternative. "Project vicinity" denotes the area within a 1.6 kilometer (1.0 mile) radius of the project area. Topography and Soils The topography of the project vicinity is characterized as rolling hills to flat. Project area elevation is approximately 53 meters (175 feet). According to the General Soil Map for Robeson County (SCS, 1978), the area within the riverbed and swamp consists of Johnston-Bibb soil association which is described as very poorly drained and poorly drained nearly level soils that have a loamy and sandy underlying material, on floodplains. Also within the project vicinity, adjacent to the swamp is mapped as Norfolk-Wagrum-McColl association which is described as well-drained, nearly level to sloping soils that have a loamy subsoil and poorly drained, nearly level soils that have a clayey and loamy subsoil on uplands. The specific map units consist of Johnston soils which are described as nearly level, very poorly drained soils that are loamy or sandy throughout, found on floodplains. Johnston soils are listed on the local hydric soils list for Robeson County. These soil types were confirmed in the field by taking soil borings with a hand auger. WATER RESOURCES This section describes each water resource and its relationship to major water systems. The proposed project lies within the Lumber River drainage basin. Water Resource Characteristics Big Raft Swamp flows under Bridge No.58 with a width of approximately 16 meters (51 feet). Big Raft Swamp has a classification of C Sw from the North Carolina Department of Environment Health and Natural Resources (NCDEHNR). Class C indicates freshwaters protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife. The class cation of Sw indicates Swamp waters which are waters which have low velocities and other natural characteristics which are different from adjacent streams. The classification index number for this portion of Big Raft Swamp is 14-10-(1). The Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps for Robeson County (1989) indicates the project area lies in Zone A, where no base flood elevations have been determined. The NCDEM has data from Big Raft Swamp at NC 211, which is located approximately 16.9 kilometers (10.5 miles) downstream from the project area; and from SR 1527, which is located approximately 22.5 kilometers (14 miles) downstream from the project area. Benthic macroinvertebrates, or benthos, are organisms that live in and on the bottom substrates of rivers and streams. The use of benthos data has proven to be a reliable tool as benthic macroin vertebrates are sensitive to subtle changes in water quality. Criteria have been developed to assign bioclassifications ranging from "Poor" to "Excellent" to each benthic sample based on the number of taxa present in the intolerant groups Ephemeroptera, Plecoptera and Trichoptera (EPT). Different criteria have been developed for different ecoregions (mountains, piedmont, coastal) within North Carolina. Data from the NC 211 sampling station taken in September 1991 as well as in December 1988 indicated a bioclassification of "good/fair". Data from the SR 1527 sampling station from December 1988 indicated a bioclassification of "good". The NCDEM also uses the North Carolina Index of Biotic Integrity (NCIBI) as another method to determine general water quality. The method was developed for assessing a stream's biological integrity by examining the structure and health of its fish community. The scores derived from the index are a measure of the ecological health of the waterbody and may not necessarily directly correlate to water quality. There is no NCIBI data available for Big Raft Swamp. The Public Water Supply Watershed Map for Robeson County indicates that the project area is not within a Critical Area. There are no water resources classed as High Quality Waters (HQW), water supplies (WS-1 or WS-11), or Outstanding Resource Waters (ORW) within 1.6 kilometers (1.0 miles) of the project area. A review of any point source dischargers that are located within the project vicinity was also conducted. Point source dischargers located throughout North Carolina are permitted through the National Pollution Discharge Elimination System (NPDES) program. Any discharger is required to register for a permit. There are no point source dischargers within the project vicinity. Non-point source refers to runoff that enters surface waters through stormwater flow or no defined point of discharge. In the project area, stormwater runoff from NC 71 appears to be the main source of water quality degradation as no residential, commercial, or agricultural areas are within the project area. Anticipated Impacts to Water Resources Impacts to the water resources will result due to the placement of support structures in the river channel. in the short term, removal of trees which provide shade in the adjacent cypress-gum swamp will likely result in an increase in water temperatures, and construction of the bridge and approach work will increase sediment loads. Although flow is very slow in these areas, additional sediment loading can reduce flow further and result in a decrease in oxygen levels. The NCDOT, in cooperation with NCDEM, has developed a sedimentation control program for highway projects which adopts formal Best Management Practices for the Protection of Surface Waters. The following are methods to reduce sedimentation and water quality impacts: strict adherence to NCDOT's Best Management Practices for the Protection of Surface Waters during the life of the project. reduction and elimination of direct and non-point discharge into the water bodies and minimization of activities conducted in streams placement of temporary ground cover or re-seeding of disturbed sites to reduce runoff and decrease sediment loadings. reduction of clearing and grubbing along streams. BIOTIC RESOURCES Living systems described in the following sections include communities of associated plants and animal. These descriptions refer to the dominant flora and fauna in each community and the relationship of these biotic components. Classification of plant communities is based on a system used by the NCNHP (Schafale and Weakley, 1990). Scientific nomenclature and common names (when applicable) are used for the plant and animal species described. Subsequent references to the same species include the common name only. Vascular plant names follow nomenclature found in Radford et al. (1968). Terrestrial and aquatic wildlife were determined through field observations, evaluation of habitat, and review of field guides and other documentation (Conant, 1958; Farrand, 1993; Robbins et al., 1966; and Whitaker, 1980). Terrestrial Communities The predominant terrestrial communities found in the project study area are man-dominated and cypress-gum swamp. Dominant faunal components associated with these terrestrial areas will be discussed in each community description. Many species are adapted to the entire range of habitats found along the project alignment, but may not be mentioned separately in each community description. Man-Dominated Community This highly disturbed community within the project area includes the road shoulders and the power line easement to the south of the bridge (Figure 2). Many plant species are adapted to these disturbed and regularly maintained areas. Regularly mowed and maintained areas along the road shoulders are dominated by fescue (Festuca spp.), ryegrass (Lolium spp.), white clover (Trifolium repens), dandelion (Taraxacum officinale), wild onion (Allium cemuum). Within the power line easement, which is less regularly maintained, are species such as dog fennel (Eupatorium capillffolium), blackberry (Rebus spp.), aster (Aster spp.), greenbrier (Smilax rotundifolia), muscadine grape (Vi6s rotundifolia), and common morning glory Qpomea purpurea). In the northeast quadrant adjacent to the road shoulders is an area dominated by a dense stand of Chinese privet (Ligustrum sinense). The animal species present in these disturbed habitats are opportunistic and capable of surviving on a variety of resources, ranging from vegetation (flowers, leaves, fruits, and seeds) to both living and dead faunal components. Although only an American crow (Corvus brachyrhynchos) was observed during the site visit, species such as raccoon (Procyon lotor), Virginia opossum (Didelphis virginiana), several species of mice (Peromyscus spp.), Eastern garter snake (Thamnophis sirtalis sirtalis), Eastern blue bird (Sialia sialis), American goldfinch (Cardeulis tristis), Northern mockingbird (Mimus polyglottos), and American robin (Turdus migratorius) are often attracted to these disturbed habitats. In addition, species such as the gray catbird (Dumetella carolinensis), brown thrasher (Toxostoma nrfum), and white eyed vireo (Vireo griseus) may utilize the dense stand of Chinese privet in the northeast quadrant. Cypress-Gum Swamp This forested community occurs in all quadrants of the bridge as well as along the swamp banks throughout the project area. The dominant canopy trees include bald cypress (Taxodium distichum), black gum (Nyssa sylvadca var. biflora), red maple (Ater ?ubrum), and willow oak (Quercus phellos). The understory consists of red maple, black titi (Cyrilla racemiflora), and loblolly bay (Gordonia iasianthus). The shrub layer includes blackberry, wax myrtle (Myrica cerifera), Chinese privet and Japanese honeysuckle (Lonicera japonica). The herbaceous layer includes giant cane (Arundinaria gigantea), common greenbrier, muscadine grape and plumegrass (Erianthus spp.), rush (Juncus spp.), switchgrass (Panicum spp.), bushy seedbox (Ludwigia altemifolia), and smartweed (Polygonum spp.). The soil within the swamp forest community is a black (10 YR 3/1) coarse silty sand which is saturated to the surface. Other hydrologic indicators throughout the site includes standing water, buttressing of tree trunks, and water marks and drift lines on trees. On the day of the site visit, a tufted titmouse (Parus bicolor), several rusty blackbirds (Euphagus carolinus), pileated woodpecker (Dryocopus pileatus), red-bellied woodpecker (Melanerpes carolinus), blue jay (Cyanocitta cristata), and American crows were observed in the field. Signs of raccoon were also observed. Other animals which may be present in this habitat include the great blue heron (Ardea herodias), common yellowthroat (Geothlypis trichas) Carolina wren (Thryothorus ludovicianus), parula warbler (Parula americana), Acadian flycatcher (Empidonax virescens), brown water snake (Natrix taxispilota), Southern leopard frog (Rana utricularia), muskrat (Odatra zibethica), and marsh rabbit (Sylvilagus palustris). Aquatic Communities The aquatic community in the project area exists within Big Raft Swamp. Within the area under Bridge NO. 58, the swamp is approximately 16 meters (51 feet) wide. The swamp widens on either side of the bridge and dominates the areas immediately adjacent to the road shoulders. On the day of the field investigation the water was slow moving and colored by tannins. The bottom was not visible. Vegetation within the swamp includes bald cypress, black gum, and red maple. Animals which may reside within the swamp and along the waters edge are listed in the man-dominated section; other species include the belted kingfisher (Megaceryle alcyon), red-bellied water snake (Natrix erythrogaster), Eastern cottonmouth (Agkistrodon piscivorus piscivorus), snapping turtle (Chelydra serpen6na) and bullfrog (Rana catesbeiana). On the day of the site visit, the water within the project area was very slow moving and contained no riffle areas, thus it was unlikely to find a diverse macroinvertebrate community. Due to the depth and siltation in this river, the macroinvertebrate community would be restricted to the shallow areas along the river banks. Although these shallow areas were sampled by dip netting, no macroinvertebrates were observed. According to Keith Ashley, District 4 Biologist for the North 'Carolina Wildlife Resources Commission (NCWRC), the following fish species are found within Big Raft Swamp: largemouth bass (Micropterus salmoides), sunfish (Lepomis spp.), bluegill (Lepomis macrochirus), warmouth (Lepomis gulosus), redbreast sunfish (Lepomis auritus), chain pickerel (Esox niger), and redfin pickerel (Esox americanus). North Carolina Wildlife Resources Commission request that there be no in-stream work between April 1 and June 15 to avoid interfering with fish reproduction. 8 Anticipated Impacts to Biotic Communities Biotic community impacts resulting from project construction are addressed separately as terrestrial impacts and aquatic impacts. However, impacts to terrestrial communities, particularly in wetland areas and in locations exhibiting gentle slopes, can result in the aquatic community receiving heavy sediment loads as a consequence of erosion. It is important to understand that construction impacts may not be restricted to the communities in which the construction activity occurs. Efforts should be made to ensure that no sediment leaves the construction site. Table 1 details the anticipated impacts to terrestrial and aquatic communities by habitat type. TABLE 1 ANTICIPATED IMPACTS TO TERRESTRIAL and AQUATIC COMMUNITIES HECTARES (ACRES). Bridge NO. 58 Man- Cypress- Gum Aquatic Combined Total Replacement Dominated Swamp Community Impacts Community Alternate A 0.36 (0.90) 0.30 (0.75) 0.05 (0.12) 0.71 (1.77) Temporary 0.33 (0.82) 0.33 (0.82) 0.06 (0.15) 0.72(l.79) Alternate B 0.48(l.19) 0.49(l.22) 0.06 (0.15) 1.03 (2.56) Alternate C 0.27 (0.67) 0.23 (0.58) 0.05 (0.12) 0.55(l.37) Terrestrial Communities The cypress-gum swamp and the man-dominated communities serve as nesting, foraging and shelter habitat for fauna. Removal of plants and other construction related activities will result in the displacement and mortality of faunal species in residence. Individual mortalities are likely to occur to terrestrial animals from construction machinery used during clearing activities. Calculated impacts to terrestrial resources reflect the relative abundance of each community present in the study area. Project construction will result in clearing and degradation of portions of these communities. Often, project construction does not require the entire right-of-way, therefore, actual impacts may be considerably less. Alternate A (Recommended) will result in an overall impact of 1.43 hectares (3.56 acres) including a permanent combined total of 0.71 hectare (1.77 acre), and temporary impact of 0.72 hectare (1.79 acre). Aquatic Communities The aquatic community in the study area exists within Big Raft Swamp. Altemate C will result in the least amount of disturbance of stream bottom (0.05 hectare/0.12 acre). Alternate A (which includes a temporary detour) will result in up to 0.11 hectare (0.27 acre) of stream bottom. 9 (This represents worst case conditions; actual disturbance area will be less). In addition, impacts to the adjacent cypress-gum swamp can have a direct impact on aquatic communities. Activities such as the removal of trees in the swamp, as well as the construction of the bridge and approach work will likely result in an increase in sediment loads and water temperatures and a decrease in dissolved oxygen in the short term. Potential adverse effects to surface waters will be minimized through the implementation of NCDOT's Best Management Practices for the Protection of Surface Waters. Since Big Raft Swamp potentially contains anadromous fish spawning habitat, the NCDOT's "Stream Crossing Guidelines for Anadromous Fish Passage" will be adhered to for this project. The purpose of these guidelines is to provide guidance to NCDOT to ensure that replacement of existing and new highway stream crossing structures will not impede the movement of anadromous fish. SPECIAL TOPICS Jurisdictional Issues Waters of the United States: Wetlands and surface waters fall under the broad category of "Waters of the United States" as defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344). Waters of the United States are regulated by the United States Army Corps of Engineers (USACOE). Wetlands will be impacted by the subject project as Big Raft Swamp is surrounded by cypress- gum swamp within the bridge replacement corridor. Investigation into wetland occurrence in the project impact area was conducted using methods of the 1987 Wetland Delineation Manual. Permanent wetland impacts due to the project will be up to 0.30 hectare (0.75 acres). Temporary wetland impacts due to the project will be up to 0.33 hectare (0.82 acres). Project construction cannot be accomplished without infringing on jurisdictional surface waters. Anticipated surface water impacts fall under the jurisdiction of the USACOE. Up to 0.11 hectare (0.27 acre) (including temporary impacts) of jurisdictional surface water impacts may occur due to the proposed replacement of Bridge NO. 58. Permits In accordance with provisions of Section 404 of the Clean Water Act (33 U.S.C.O.E. 1344), a permit will be required from the USACOE for the discharge of dredged or fill material into "Waters of the United States". Since the subject project is classed as a Categorical Exclusion, it is likely that this project will be subject to the Nationwide Permit Provisions of 33 CFR 33-.5 (A) 23. This permit authorizes any activities, work and discharges undertaken, assisted, authorized, regulated, funded or financed, in whole or in part, by another federal agency and that the activity is "categorically excluded" from environmental documentation because it is included within a category of actions 10 which neither individually or cumulatively have a significant effect on the environment. However, final permit decisions are left to the discretionary authority of the USACOE. A 401 Water Quality Certification, administered through the North Carolina Department of Environment, Health and Natural Resources (NCDEHNR), will also be required. This certificate is issued for any activity which may result in a discharge into waters for which a federal permit is required. Mitigation Mitigation for impacts to wetlands exceeding one acre will be required by both the USACOE and the North Carolina Division of Water Quality (NCDWQ). Wetlands will be delineated prior to submittal for permit application. Mitigation for impacts to surface waters may be required by the USACOE and NCDWQ. A final determination regarding mitigation to waters of the U.S. rest with USACOE and NCDWQ. All borrow and solid waste sites will be the responsibility of the Contractor. Solid waste will be disposed of in strict adherence to the NC Division of Highways "Standard Specifications for Roads and Structures". The Contractor will observe and comply with all laws, ordinances, regulations, orders, and decrees regarding the disposal of solid waste. Solid waste will not be placed into any existing land disposal sites that is in violation of state or local rules and regulations. Waste and debris will be disposed of in areas that are outside the right-of-way and provided by the Contractor. The Contractor will be responsible for obtaining borrow sites, delineating wetlands in borrow sites and obtaining written concurrence on delineated wetlands in borrow sites from the Corps of Engineers. Borrow material will not be stockpiled or disposed of adjacent to or in areas where they may runoff with stormwater into streams and impoundments. Where it is absolutely necessary to store materials adjacent to streams, they will be stored above the mean high-water mark in such a manner that they would not runoff with stormwater. Disposal of waste and debris will not be allowed in areas under the Corps of Engineers regulating jurisdiction. In the event that COE jurisdictional areas cannot be avoided, the Department will be responsible for mitigation. The Contractor will maintain the earth surface of all waste areas, both during the construction phase and until the completion of all seeding and mulching, or other erosion control measures specified, in a manner that will effectively control erosion and siltation into areas under the Corps of Engineers regulatory jurisdiction, streams and impoundments. Rare and Protected Species Some populations of plants and animals are in the process of decline due either to natural forces or their inability to coexist with humans. Rare and protected species listed for Robeson County, and any likely impacts to these species as a result of the proposed project construction, are discussed in the following sections. 11 Federally Protected Species Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. The United States Fish and Wildlife Service (USFWS) lists three federally protected species for Robeson County as of the May 2, 1997 listing. These species are listed in Table 2. TABLE 2 FEDERALLY-PROTECTED SPECIES FOR ROBESON COUNTY Scientific Name Status Common Name Alligator mississippiensis T (S/A) American alligator) Picoides borealis E Red-cockaded woodpecker) Rhus michauxii E Michaux's sumac NOTES: E Denotes Endangered (a species that is In danger of extinction throughout all or a significant portion of its range) T (S/A) Denotes Threatened based on similarity of appearance. The American alligator is a large (1.8 to 3.7 meters / 6 to 12 feet long) rough-backed reptile with a broad, rounded snout. Its fourth tooth on the lower jaw fits into a notch in the lower jaw. This characteristic distinguishes the American alligator from the American crocodile which has its fourth tooth exposed when the jaw is closed. American alligators are sexually mature at about 6 or 7 years of age. Nesting occurs in late spring or early summer when females produce approximately 35 to 40 eggs. American alligators inhabit fresh to slightly brackish river systems, canals, lakes, ponds, swamps, bayous, and coastal marshes. The American alligator is not federally protected and is not afforded legal protection under Section 7 of the Endangered Species Act. The Red-cockaded woodpecker is a small (18-20 cm long) bird with a black and white horizontal stripes on its back, a black cap and a large white cheek patch. The male has a small red spot or "cockade" behind the eye. The preferred nesting habitat of the Red-cockaded woodpecker is open stands of pines with a minimum age of 60 to 120 years. Longleaf pines (Pious palustris) are preferred for nesting; however, other mature pines such as loblolly (Pinus taeda) may be utilized. Typical nesting areas, or territories, are pine stands of approximately 81 hectares (200 acres), however, nesting has been reported in stands as small as 24 hectares (60 acres). Preferred foraging habitat is pine and pine-hardwood stands of 80 to 125 acres with a minimum age of 30 years and a 12 minimum diameter of 25 centimeters (10 inches). The Red-cockaded woodpecker utilizes these areas to forage for insects such as ants, beetles, wood-boring insects, caterpillars, as well as seasonal wild fruit. This habitat type does not exist in the project area; there are no stands of old growth pines within or adjacent to the study area. A search of the NCNHP database showed no recorded occurrences of this species within the project vicinity. it can be concluded that the construction of proposed project will not impact the Red-cockaded woodpecker. BIOLOGICAL CONCLUSION: NO EFFECT Michaux's sumac is a densely hairy shrub with erect stems which are 0.3 to 0.9 meters (1 to 3 feet) in height. The shrub's compound leaves are narrowly winged at their base, dull on their tops, and veiny and slightly hairy on their bottoms. Each leaflet is finely toothed on its edges. The flowers are greenish-yellow to white and are 4-5 parted. The plant flowers from April to June. Michaux's sumac is found in sandy or rocky open woods in association with basic soils. This plant survives best in areas where some form of disturbance has provided an open area. The project area includes cypress-gum swamp and regularly maintained road shoulders which are not suitable habitat for this species. The road shoulder / wooded area edge is too wet to provide suitable habitat A search of the NCNHP database showed no recorded occurrences of this species within the project vicinity. it can be concluded that construction of the proposed project will not impact Michaux's sumac. BIOLOGICAL CONCLUSION: NO EFFECT Federal Species of Concern Federal Species of Concern (FSC) are not legally protected under the Endangered Species Act and are not subject to any of its provisions, including Section 7, until they are formally proposed or listed as Threatened of Endangered. Species designated as FSC are defined as taxa which may or may not be listed in the future. These species were formerly Candidate 2 (C2) species or species under consideration for listing for which there is insufficient information to support listing. Some of these species are listed as Endangered, Threatened, or Special Concern by the NCNHP list of Rare Plant and Animal Species and are afforded state protection under the State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of 1979; however, the level of protection given to state listed species does not apply to NCDOT activities. Table 3 includes listed FSC species for Robeson County and their state class cations. 13 TABLE 3 FEDERAL SPECIES OF CONCERN ROBESON COUNTY Scientific Name North Carolina Habitat Present (Common Name) Status Aimophila aesdvalis SC No Bachman's sparrow) Corynorhinus rafinesquii SC No Rafines ue's big-eared bat Heterodon simus SR No Southern ho nose snake Rana capito capito SC No Carolina gopher fro Amorpha georgiana var. georgiana* E No (Georgia indigo-bush) Astragalus michauxii* C No Sandhills milkvetch Dionaea muscipula C-SC No Venus "rap) Echinodorus parvulus C Yes Dwarf burhead Lindera subcoriacea E No Bo s icebush Macbridea caroliniana C Yes Carolina bo mint Rhexia aristosa T No (awned meadowbeauty) NOTES: Indicates no specimens have been found in at least 20 years.

A review of the NCNHP database revealed no occurrences of any FSC or state protected species within the project vicinity. Summary of Anticipated Impacts Habitat is present in the project area for the American alligator; however, this species is listed as threatened due to similarity of appearance with other rare species and are not biologically endangered or threatened and are not subject to Section 7 consultation. Habitat also exists on the site for two Federal Species of Concern and for four additional state listed species. No individuals were observed at the time of the site visit. No impacts to federally protected species will result from any of the proposed project alternatives. 15 VIII. CULTURAL EFFECTS This project is subject to compliance with Section 106 of the National Historical Preservation Act of 1966, as amended and 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 the opportunity to comment. In a Concurrence Form, dated January 16, 1997 the State Historic Preservation Officer (SHPO) concurred that there are no historic architectural resources either listed in or eligible for listing in the National Register of Historic Places located in the project's area of potential effect. A copy of the SHPO letter is included in the Appendix. The SHPO, in a memorandum dated December 4, 1996, stated that there are no known archaeological sites within the proposed project area. Therefore, the SHPO recommended that no archaeological investigation be conducted in connection with this project. A copy of the SHPO memorandum is included in the Appendix. IX. ENVIRONMENTAL EFFECTS The project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. The bridge replacement will not have an adverse effect on the quality of the human or natural environment, provided that current NCDOT standards and specifications are used. The project is not in conflict with any plan, existing land use, or zoning regulation. No significant change in land use is expected to result from construction of the project. No adverse impact on families or communities is anticipated. No relocatees are expected with implementation of the proposed alternatives. 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. 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. No geodetic survey markers will be impacted. The Farmland Protection Policy Act requires all federal agencies or their representatives to consider the potential impacts to prime and important farmland soils by all land acquisition and construction projects. Prime and important farmland soils are defined by the U.S. Soil Conservation Service (SCS). Since the bridge will be replaced at the existing location, the Farmland Protection Policy Act does not apply. 16 This project is an air quality "neutral" project, so it is not required to be included the regional emission analysis (if applicable) and a project level CO analysis is not required. The project is located in Robeson County, which has been determined to be in compliance with the National Ambient Air Quality Standards. 40 CFR Part 51 is not applicable because the proposed project is located in an attainment area. This project is not anticipated to create any adverse effects on the air quality of this attainment area. This project will not increase or decrease the traffic volumes in the area. There are no receptors located in the immediate project area. The projects impact on noise and air quality will not be significant. Noise levels could increase during construction 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 SIP air quality in compliance with 15 NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic noise (23 CFR Part 772) and for air quality (1990 CAAA and NEPA) 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. Robeson County is a participant in the National Flood Insurance Program. The approximate 100 year floodplain in the project area is shown in Figure 4. The amount of floodplain area to be affected is not considered to be significant. On the basis of the above discussion, it is concluded that no significant adverse environmental effects will result from implementation of the project. The project is a Federal "Categorical Exclusion" due to its limited scope and lack of significant environmental consequences. 17 REFERENCES Burt, W.H. and R.P. Grossenheider. 1952.

Crow, Director Thank you for your letter of November 5, 1996, concerning the above project. We have conducted a search of our maps and files and have located the following structures of historical or architectural importance within the general area of the project: Bridge #58. This bridge was built in 1931. We recommend that Bridge #58 be evaluated for National Register of Historic Places eligibility. We look forward to meeting with an architectural historian from the North Carolina Department of Transportation to review the aerial and photographs of the project area so we can make our survey recommendation. 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.

Salisbury Street, Raleigh, North Carolina 27604-1188, 919-733-3391 Charles R. Fullwood, Executive Director MEMORANDUM TO: Mr. Joe Westbrook NCDOT Planning and Environmental Branch FROM: David Cox, Highway Project Coor Habitat Conservation Program DATE: January 6, 1997 SUBJECT: Replacement of Bridge No. 58 on NC 71 over Big Raft Swamp, Robeson County, North Carolina, TIP No. B-3029. Biologists with the N. C. Wildlife Resources Commission (NCWRC) have reviewed the information provided regarding potential impacts to wildlife and fisheries resources. Our comments are provided in accordance with provisions of the National Environmental Policy Act (42 U.S.C. 4332(2)(c)) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). We recommend replacement of the existing structure with a bridge, on-site with an off- site detour. If widening bridge approaches is necessary, this should be done accomplished to the downstream side, minimizing wetland impacts. We also request that there be no in-stream work between April 1 and June 15 to avoid interfering with fish reproduction. In addition to any specific comments above, the NCWRC requests NCDOT routinely minimize adverse impacts to fish and wildlife resources in the vicinity of bridge replacements. The NCDOT should install and maintain sedimentation control measures throughout the life of the project and prevent wet concrete from contacting water in or entering into these streams. Replacement of bridges with spanning structures of some type, as opposed to pipe or box culverts, is recommended in most cases. Spanning structures allow wildlife passage along streambanks, reducing habitat fragmentation and vehicle related mortality at highway crossings. Any channel relocations should be done using state-of-the-art stream relocation techniques and should be coordinated with the NCWRC. If you need further assistance or information on NCWRC concerns regarding bridge replacements, please contact me at (919) 528-9886. Thank you for the opportunity to review and comment on this project. State of North Carolina Department of Environment, Health and Natural Resources / • • Division of Water Quality Ja mesB. Hunt, Jr., Governor Jonathan B. Howes, Secretary A. Preston Howard, Jr., P.E., Director January 16, 1997 MEMORANDUM T, : Mr. Joe Westbrook, NCDOT, Planning & Environmental A _ From: Cyndi Bell, NC Division of Water Quality L E3 - Subject: Water Quality Checklist for Bridge Replacement Projects Reference your correspondence dated November 5, 1996, in which you requested comments concerning the scope of work to be performed by Wang Engineering Company, Inc. The Division of Water Quality requests that NCDOT and its consultant consider the following generic environmental commitments for design and construction of bridge replacements: A. DWQ 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), HQW (High Quality Water), B (Body Contact), SA (Shellfish Water) or Tr (Trout Water) classifications to protect existing uses. B. DWQ requests that bridges be replaced on existing location with road closure. If an on-site detour or bridge/approach road realignment is necessary, the approach fills should be removed to pre-construction contour and revegetated with native vegetation. Tree species should be planted at 320 stems per acre. C. DWQ requests that hazardous spill catch basins be installed at any bridge crossing a stream classified as WS (Water Supply). The number of catch basins installed should be determined by the design of the bridge, so that runoff would enter said basin(s) rather than directly flowing into the stream. D. To the maximum extent practicable, DOT should not install the bridge bents in the creek. E. 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 will be required by DWQ if impacts exceed one acre. Smaller impacts may soon require mitigation by the U.S. Army Corps of Engineers. F. Borrow/waste areas should not be located in wetlands. It is likely that compensatory mitigation will be required if wetlands are impacted by waste or borrow. The attached table has been prepared by DWQ for your assistance in studying the systems involved in these bridge replacements. This information includes the DWQ Index Number, DWQ Stream Classification, river basin, and preliminary comments for each crossing. P.O.

Accordingly, we offer the following comments and recommendations to be addressed in the planning report: a. The report should contain the amount of permanent and temporary impacts to waters and wetlands as well as a description of the type of habitat that will be affected. b. Off-site detours are always preferable to on-site (temporary) detours in wetlands. If an on-site detour is the recommended action, justification should be provided. c. Project commitments should include the removal of all temporary fills from waters and wetlands. In addition, if undercutting is necessary for temporary detours, the undercut material should be stockpiled to be used to restore the site. d. The report should address impacts to recreational navigation (if any) if a bridge span will be replaced with a box culvert. e. The report should address potential impacts to anadromous fish passage if a bridge span will be replaced with culverts. Thank you for the opportunity to comment during this phase of planning for these projects. Questions or comments may be addressed to me in the Wilmington Regulatory Field office at (910) 251-4725.

Franklin Vick, P.E., Manager Planning and Environmental Branch North Carolina Division of Highways Post Office Box 25201 Raleigh, North Carolina 27611-5201 Dear Mr. Vick: This is in response to your multiple memorandums of November 5, 1996, requesting our scoping comments on the replacements of three bridges in Robeson County and two bridges each in Sampson and Onslow Counties. Complete information on these projects was not received in our office until late January. Comments on these bridge replacements are to be used in Planning and Environmental Studies (Categorical Exclusions). Our comments involve impacts to flood plains and jurisdictional resources, which include waters, wetlands, and U.S. Army Corps of Engineers projects. The proposed projects would not cross any Corps-constructed flood control or navigation project. Enclosed are our comments on the other issues. We appreciate the opportunity to comment on these projects. If we can be of further assistance, please contact us. Sincerely, C. E. Shuford, Jr., P.E. Acting Chief, Engineering and Planning Division Enclosure March 3, 1997 Page 1 of 1 U.S. ARMY CORPS OF ENGINEERS, WILMINGTON DISTRICT, COMMENTS ON: Bridge Replacements in Robeson, Sampson, and Onslow Counties (Categorical Exclusions) 1. FLOOD PLAINS: POC - Mr. Bobby L. Willis, Special Studies and Flood Plain Services Section, at (910) 251-4728 The proposed projects are located in Robeson and Sampson Counties and within the jurisdiction of the city of Jacksonville in Onslow County, all of which participate in the National Flood Insurance Program. From a review of the various Flood Insurance Rate Maps (FIRMs) for Robeson and Sampson Counties, it appears that the affected streams are mapped approximately. From Panel 6 of the February 1985 Jacksonville Flood Boundary and Floodway Map, the SR 1406 crossing is on a detailed study portion of Northeast Creek, which has 100-year flood elevations determined and a foodway defined. A summary of flood plain information pertaining to these bridges is contained in the following table. The FIRMs are from the county flood insurance study except for the city of Jacksonville.

HUNT JR. GOVERNOR DAVID MCCOY SECRETARY September 29, 2000 US Army Corps of Engineers Wilmington Field Office P. O. Box 1890 Wilmington, North Carolina 28402-1890 ATTENTION: Mr. David Timpy NCDOT Coordinator Dear Sir: Subject: Robeson County, Replacement of Bridge No. 58 over Big Raft Swamp on NC 71, Federal Project No. BRSTP-71(2), State Project No. 8.146270 1, T.I.P. No. B-3029. AID No. 199701747. Bridge No. 58 will be replaced on existing alignment with a new bridge approximately 37 meters (120 feet) in length and 9.6 meters (32 feet) wide. On April 7, 2000 we submitted a request for a Nationwide 23 verification for the subject project. Since that time we have refined the design of the project. We have eliminated the on-site temporary detour. The traffic will be detoured on existing secondary roads thus decreasing the temporary jurisdictional impacts by 0.88 acres. As noted in our April 7, 2000 application there will be 0.38 acres of permanent impact consisting of 0.052 acres of fill in wetlands and 0.33 acres of mechanized clearing. At the request of the North Carolina Wildlife Resources Commission (WRC), there will be a moratorium of instream work from April 1 and June 15 to avoid interfering with fish reproduction. If you have any questions or need additional information please call Ms. Alice N. Gordon at 733-7844 extension 288. Sincerely, William D.
