No. B-2567 Bridge No. 55 is included in the current Transportation Program. The location is shown in Figure 1. No substantial impacts are anticipated. The project has been classified as exclusion." Improvement environmental a "categorical I. SUMMARY OF RECOMMENDATIONS Bridge No. 55 should be replaced at its existing location as shown by Recommended Alternate 1 in Figure 2. The recommended structure is a bridge 190 feet long and 28 feet wide. This alternate will provide a 22-foot travelway across the structure with three feet of lateral clearance on each side. Minor improvements to the existing approaches will be necessary for a distance of about 100 feet on each side of the bridge. The approach roadway should consist of a 22-foot travelway with 6-foot grassed shoulders. The roadway grade of the new structure will be approximately the same as the existing grade at this location. Traffic should be detoured along existing secondary roads during the construction period, as shown in Figure 1. Estimated cost, based on current prices, is $ 467,000. The estimated cost of construction and right of way of the project, as shown in the 1995-2001 Transportation Improvement Program, is $ 683,000. II. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures will be implemented to avoid and minimize environmental impacts. Approximately 0.09 acre of wetlands will be disrupted by implementation of this project. Best Management Practices for protection of surface waters will be strictly enforced to ensure the biological integrity of the water bodies impacted by this project. Measures will be taken to reduce the amount of probable increased concentrations of toxic compounds (gasoline, oil, etc.) in the stream coming from construction related machinery and road paving activities. Although there does not appear to be evidence of significant scour potential at this crossing, the erosive potential associated with the sharp curve in the river at this crossing warrants that careful design consideration be given to protecting the banks from erosion and scour. 2 In order to complete construction of the project during a single construction season, the project should be let to contract between November and March. This will enable the road closure time to be kept to a minimum (about seven months) such that the traveling public will be inconvenienced as little as possible. Additionally, road closure during the summer months when school is not in session will minimize inconvenience to school buses. A Section 404 permit and Division of Environmental Management (DEM) Section 401 Water Quality General Certification will be required prior to project construction. III. EXISTING CONDITIONS SR 1130 is classified as a rural minor collector in the Statewide Functional Classification System and is not a part of the Federal-Aid System. In the vicinity of the bridge, SR 1130 has an 18-foot pavement with 10-foot to 12-foot shoulders (see Figure 3). The existing bridge is on a tangent alignment with the south approach. The north approach to the bridge consists of a curve of about eight degrees. The current traffic volume of 750 VPD is expected to increase to 1400 VPD by the year 2017. The projected volume includes 1% truck-tractor semi-trailer (TTST) and 2% dual-tired vehicles (DTT). The existing bridge (see Figure 3) was constructed in 1964. The existing bridge consists of timber floor on steel I-beams with timber joists supported by timber piles and caps with timber bulkhead-type abutments. The overall length of this 8-span bridge is 160 feet and provides a clear roadway width of 19.2 feet. The posted weight limit is 11 tons for single vehicles and 15 tons for trucks with trailers. A narrow bridge sign is posted on the south approach of the bridge. Bridge No. 55 has a sufficiency rating of 7.9 compared to a rating of 100 for a new structure. The estimated remaining life of the existing bridge is 2 years. The speed limit is statutory 55 MPH. No accidents were reported in the vicinity of Bridge No. 55 during the period from January, 1990 to January, 1993. Four school buses travel across the studied bridge daily. IV. ALTERNATIVES Three methods of replacing Bridge No. 55 were studied. Each of the alternates studied involves a replacement structure 190 feet long and 28 feet wide. This structure width will accommodate a 22-foot travelway across the structure with three feet of lateral clearance on each side. The approach roadway will consist of 22 feet of pavement with 6-foot grassed shoulders. r 3 The alternates studied, shown in Figure 2, are as follows: Alternate 1 (Recommended) - replace the bridge at its present location. Approximately 100 feet of approach roadway work is required. The design speed is about 55 MPH. Traffic is to be detoured along existing roads, as shown in Figure 1. Alternate 2 - replace the bridge at its existing location. The approach roadway work in conjunction with this alternate extends about 500 feet north and 500 feet south of the new structure. The design speed would be about 55 MPH. Traffic would be maintained during construction by provision of a temporary 100-foot long bridge located immediately east (downstream) of the existing bridge. Alternate 3 - replace the structure on new location approximately 60 feet east of the existing bridge. This alternate would involve approximately 1500 feet of new approach roadway. Traffic would be maintained on the existing structure during the construction period. The design speed would be about 50 MPH. The "do-nothing" alternative would eventually necessitate closure of the bridge. This is not prudent due to the traffic service provided by SR 1130. 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. V. ESTIMATED COST Estimated costs of the alternatives studied are as follows: Recommended Alternate 1 Alternate 2 Alternate 3 Structure $ 319,000 $ 319,000 $ 319,000 Roadway Approaches 58,000 101,000 276,000 Detour Structure & -- 275,000 -- Approaches Structure Removal 19,000 19,000 19,000 Engineering & 54,000 111,000 86,000 Contingencies Right-of-Way, 17,000 27,000 23,000 Utilities Total $ 467,000 $ 852,000 $ 723,000 4 VI. TRAFFIC DETOUR The division engineer concurs that traffic can be detoured on existing roads during the construction period, as shown in Figure 1. The average vehicle will be required to travel an additional 4.4 miles. A seven-month road closure period is anticipated. Maintaining traffic on-site is estimated to cost an additional $ 256,000 , and is not justifiable due to the excessive cost of the on-site detour and the availability of a suitable detour route. The detour roadway and bridges are adequate to accommodate affected traffic during the construction period. A road user analysis (based on 800 VPD and an average of 4.4 miles of indirectional travel) indicates the cost of additional travel would be approximately $ 222,000 during the seven-month construction period. The estimated cost of maintaining traffic on-site during construction is $ 256,000, resulting in a benefit-cost ratio of 0.9. This ratio indicates that detouring traffic.along secondary roads is economically justifiable. The Harnett County School Bus Supervisor indicates road closure of SR 1130 is tolerable. However, road closure should occur during the summer months when school is not in session to minimize inconvenience to school buses. , VII. RECOMMENDED IMPROVEMENTS Bridge No. 55 should be replaced at its existing location with a new structure having a length of approximately 190 feet, as shown by Recommended Alternate 1 in Figure 2. Minor improvements to the existing approaches will be necessary for a distance of about 100 feet on each side of the bridge. A 22-foot travelway with 6-foot grassed shoulders will be provided on the approaches. A 28-foot clear roadway width is recommended on the replacement structure in accordance with current Bridge Policy. This will provide a 22-foot travelway across the structure with three feet of lateral clearance on each side. Based on preliminary studies, the Hydraulics Unit recommends the new structure should have a length of approximately 190 feet. The new bridge grade should be essentially the same as that of the existing bridge, except the north end of the new bridge and the north roadway approach grade should be raised slightly to accommodate a minimum gradient of 0.3% along the bridge to ensure positive drainage of the deck. The length and height may be increased or decreased as necessary to accommodate peak flows as determined by further hydrological analysis and hydraulic design. Traffic will be detoured on existing roads during the seven-month construction period, as shown in Figure 1. The division engineer concurs with the recommendation of Alternate 1. 5 VIII. ENVIRONMENTAL EFFECTS The project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. The project is considered to be a "categorical exclusion" due to its limited scope and insignificant environmental consequences. The bridge replacement will not have a substantial 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 regulation. No change in land use is expected to result from construction of the project. No adverse effect on families or communities is anticipated. Right-of-way acquisition will be limited. No adverse effect on public facilities or services is expected. 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. The 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 if a federally-funded, licensed, or permitted project has an effect on a property listed on or eligible for inclusion in the National Register of Historic Places, the Advisory Council on Historic Preservation be given the opportunity to comment. Photographs, maps, and information about the area of potential effect were provided by the North Carolina Department of Transportation and reviewed with the State Historic Preservation Office (SHPO). There are no historic structures within the area of potential effect, and the SHPO recommended that no historic architectural survey be conducted for this project. Correspondence from the SHPO is included as Attachment 1. An archaeological survey was conducted for this bridge replacement project to locate and assess any significant archaeological remains that could be damaged or destroyed. No historic or prehistoric cultural resources were discovered. The results of the archaeological survey indicate the project is unlikely to encounter any archaeological sites that are eligible for listing on the National Register of Historic Places. The SHPO concurs that no further archaeological investigation be conducted in connection with this project since the project will not involve significant archaeological resources. Correspondence from the SHPO regarding the archaeological aspects of the project is included as Attachment 2. 6 The structure is to be replaced at the existing location. Therefore, the project is exempt from the Farmland Protection Policy Act. The proposed project occurs in south-central Harnett County, approximately 3 miles south of Lillington. The project is located in a forest dominated rural setting. Elevation of the project area is 200 feet above mean sea level. Harnett County is in the Upper Coastal Plain Physiographic Province. The topography of the area is characterized as gently sloping, with broad nearly level floodplains. This region is a transition zone between the Piedmont and Coastal Plain. The soils of this area reflect this transition, with parent material formed from exposed felsic crystalline and slate belt rock, overlain with fluvial and marine sediments. The soils of the plains of the project area are well drained fine sandy loams of the Altavista series. The slopes leading to the stream have well drained soils of the Louisa fine sandy loam and Pacolet fine sandy loam Series, while the soils of the floodplain are generally poorly drained loams of the hydric Wehadkee Series. Upper Little River is in the Cape Fear River system, originating approximately 17 miles to the northwest in Lee County and flowing in a general eastward direction into the Cape Fear River near Erwin, 12 miles downstream of project crossing. Stream width is approximately 60 feet at the project crossing. Depth is highly variable, ranging from five feet just below the bridge, down to six inches over gravel beds just upstream of the bridge. The substrate is a mixture of coarse sand and gravel, occasionally overlain with cobble. The waters of the Upper Little River carry the Best Usage Classification of C as assigned by the North Carolina Department of Environment, Health and Natural Resources (DEHNR), 1993. Class C designates waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation and agriculture. No waters classified as High Quality Waters (HQW), Outstanding Resource Waters (ORW), WS-I, or WS-II, occur within one mile of the project area. r The Benthic Macroinvertebrate Ambient Network (BMAN) assesses water quality by sampling for selected benthic Macroinvertebrate organisms. The species richness and overall biomass are reflections of water quality. Two MAN survey stations are located on Upper Little River, approximately ten miles upstream and eight miles downstream of project crossing respectively. The upstream location was given an "Excellent" biodiversity rating in November 1991 and most recently a "Good-Fair" rating in August 1993. The downstream location has ranged from "Excellent" in July, 1991 to "Good" in August, 1993. The DEM National Pollutant Discharge Elimination System (NPDES) report lists two permitted discharge sources into Upper Little River four and six miles downstream of the project site. These discharges are not known to effect the water quality at the project site. No permitted discharges are listed upstream near the crossing. 7 Potential impacts to water resources include decreases of dissolved oxygen and changes in temperature. These impacts are frequently due to removal of the streamside canopy and removal/burial of aquatic vegetation. Sedimentation and substrate disturbance occurring during construction can significantly reduce water clarity. M If stream channel relocation is required and if the stream relocation is r greater than 100 feet in length or greater than 50 feet to one side, consultation with the U. S. Fish and Wildlife Service and the North Carolina Wildlife Resources Commission will be required, per the Fish and Wildlife Coordination Act, as amended (16 USC 661-6674). Relocated streams will be designed to have similar characteristics (depth, width, and substrate) as the original stream. This also includes re-establishment of streamside vegetation. Three distinct biotic community types were identified in the project impact zone: maintained, steep mesic hardwood slope, and bottomland hardwood communities. However, some degree of overlap exists between communities, particularly with the faunal components. Numerous terrestrial animals are highly adaptive and populate a variety of habitats; therefore, many of the species discussed below may occur in all of the community types described. Maintained communities are land parcels in which the vegetation is kept in a low-growing, non-successional state. These communities include the existing roadside and cleared powerline corridor east of the roadway. The narrow roadside shoulder has a limited amount of vegetative growth, which is primarily fescues Festuca spp.), along with dandelion (Taraxacum officinale), chickweed Stellaria media), and wild onion Allium canadense). The area extending from the maintained community into the forest and powerline corridor is less maintained, supporting rank vegetative growth, especially at the woodland border. Species present include sheep-sorrel Rumex acetosella), winged sumac Rhus copallina), tag alder Alnus serrulata), trumpet creeper (Cam psis radicans , nightshade Solanum spp.), pokeweed (Phytolacca americana), poison ivy, blackberry Rubus sp.), and Japanese honeysuckle Lonicera japonica). Saplings of "weedy hardwoods such as sweet gum (Liquidambar styraciflua), red maple Acer rubrum , and sourwood fOxydendrum arboreum are also present. The limited roadside area does not likely support much of a resident faunal assemblage. Small animals, such as house mouse Mus musculis and five-lined skink Eumeces fasciatus), are some of the more common species to inhabit this type of habitat; however, they are abundant in several other habitat types as well. Birds, such as rufous-sided towhee Pi ilo erythrophthalmus), white-throated sparrow (Zonotrichia albicollis) and grey catbird (Dumetella carolinensis), are some species which are found in dense cover, nesting close to the ground. The dense vegetative growth also offers foraging opportunity for several species residing in the adjacent forest. Roadways also become travel corridors for many animal species. Other species take advantage of this in a variety of ways. Predatory birds, such as loggerhead shrike Lanius ludovicianus), red-tailed hawk Buteo jamaciensis), and other similar birds, prey on a wide variety of small animals exposed during their migrations across the roadway. Scavengers and 8 opportunistic feeders, such as the common crow Corvus brachyrhynchos), turkey vulture (Cathartes aura), raccoon (Procyon lotor , and Virginia opossum Didel his virginiana), take advantage of the large amount of carrion associated with roadkills. Often these species become roadkills themselves. Occurring on a steep slope, grading towards Upper Little River, the steep mesic hardwood slope community has a very diverse vegetative component. No canopy species is particularly dominant on this slope, which contains species associated with mesic and dry habitats. White oak uercus alba , black oak (Q. velutina , water oak JL. ni ra , black walnut Ju lans ni ra , American beech Fa us grandiflolia), and sweet gum (Liquidambar styraciflua) comprise the fairly dense canopy. Mountain laurel Kalmia latifolia) is the most abundant shrub species, and heartleaf (Hexastylis sp.) and pipsissewa (Chimaphila maculata are the most common herbs. Prevalent vine species include grape Vitis spp.), green brier Smilax spp.), crossvine (Anisostichus capreolata), trumpet creeper (Cam psis radicans , and poison ivy (Toxicodendron radicans . The majority of this habitat type occurs west of the roadway, and will receive minimal impacts. Canopy dwelling species comprise the majority of the faunal assemblage of this community. Because of the steep terrain, ground dwelling species are expected to be few. Tufted titmouse Parus bicolor), Carolina chickadee (P. caroliniensis), red-bellied woodpecker (Melanerpes carolinus), blue jay (Cyanocitta cristata , and grey squirrel Sciurus carolinensis) were observed to be abundant in this community. Other species found in the bottomland forest may also occur in this habitat. Another community in the project area is bottomland hardwood forest. Although a large amount of the floodplain associated with the Upper Little River is in a relatively undisturbed forested state, most of the area to be impacted by this project retains little of the original community characteristics as a result of previous disturbances. The majority of the floodplain is located adjacent to the north bank of the river and is characterized as broad, relatively flat, containing several depressions (ephemeral pools). The canopy of this community is dominated by a number of bottomland oaks, including willow oak uercus hellos , water oak (Q. ni ra , chestnut oak (Q. michauxii), along with red maple, black walnut, sweetgum, and ironwood Car inus caroliniana). Ironwood, pawpaw Asimina triloba , American holly Ilex o aca , and possumhaw (I. decidua comprise the subcanopy. The herb layer is sparsely populated with partridge berry (Mitchella re ens , sedge Carex sp.), false nettle (Boehmeria cylindrica), and violet Viola sp.). Vines, including poison ivy, grape Vitis rotundifolia), and green brier Smilax rotundifolia) are prevalent. Birds are the most prominent and conspicuous group of vertebrates found in the forest. Wood boring and defoliating insects are abundant and are consumed by birds, such as downy woodpecker Picoides pubescens), yellow-bellied sapsucker (Sphyrapicus varius , pileated woodpecker (Dryocopus ileatus , blue-gray gnatcatcher (Polioptila caerulea , yellow-throated warbler (Dendrocia dominica , white-breasted nuthatch Sitta carolinensis), swamp sparrow (Melospiza georgiana), prothonotary warbler (Protonotaria citrea , northern parula Parula americana), and wood thrush (Hylocichla mustelina). The forest contains many large mast-producing trees. Other 9 fruits and seeds are also plentiful and are consumed by these species, as well as tufted titmouse Parus bicolor), solitary vireo Vireo solitarius), and northern cardinal (Cardinalis cardinalis). The predatory barred owl Strix varia inhabits wet bottomland forests, nesting in tree cavities and hunting from tree limbs. Small mammals, frogs, insects and birds are the primary prey items. Piscivorous birds, such as great blue heron Ardea herodias , green heron (Butorides striatus , and belted kingfisher (Megaceryle alc on , may be an important component of the forest and aquatic community. Frogs, crustaceans and small invertebrates also constitute a major portion of these species' diets. Forest edges near clearings, such as roadways and fields, are preferred nesting sites for the red-shouldered hawk Buteo lineatus and scarlet tanager Piran a olivacea . Ephemeral pools formed by floodplain depressions are utilized as breeding pools for species, such as spotted salamander (Ambystoma maculata , southern cricket frog Acris r llus , spring peeper H la crucifer), and many other amphibians. Marbled (Ambystoma opaca) and southern dusky salamanders (Desmognathus auriculatus) are also found in floodplain habitats; however, they lay their eggs in damp soil, or rotting logs rather than in pools. The slimy salamander (Plethodon glutinosus) occurs in the less frequently flooded areas of this community. This wide ranging species occurs in a variety of habitats. Populations of many amphibians are in decline, for a variety of reasons, including habitat loss and degradation, as well as hydrological and climatological changes. Mammals such as raccoon (Procyon lotor), golden mouse (Ochrotomys nuttalli , and southeastern shrew Sorex longirostris) occur in a wide variety of habitats but are most abundant in forested areas near water, as are the eastern ribbon snake (Thamnophis sauritus and ringneck snake (Diadophis punctatus), which were found under logs in the dry floodplain. The aquatic community is also present in the project area. Research has shown that a large amount of food chain energy of stream communities is derived from allochthonous (produced outside of stream ecosystem) sources in the form of terrestrial detritus. Rocks, fallen debris (logs, sticks etc), and low velocity areas in the stream trap or retain detritus within the stream. The detritus is then decomposed by heterotrophic microorganisms, such as bacteria, and consumed by macroinvertebrates, such as aquatic insects. Decomposers and primary consumers are, in turn, consumed by larger organisms. The amount of allochthonous energy input within a stream varies seasonally and is dependent on the extent of streamside vegetation. Autochthonous (produced within the stream ecosystem) energy sources include planktonic and benthic micro-and-macro algae, as well as aquatic vascular vegetation. Aquatic vegetation is present in some stretches of this stream. Species present include smartweed (Polygonum sp.), pond ]illy Nu har luteum , and quillwort Isoetes sp.). Aquatic invertebrates are a major component of stream ecosystems, as primary and secondary consumers and as prey items for organisms higher in the food chain. Two species of freshwater mussels (Unionidae) are common in the stream. These are Elliptio complanata and E. congara. Aquatic insects 10 observed include whirligig beetle G rinus limbatus and common backswimmer (Notonecta undulata . These, along with larval forms of other insects, including mayflies (Ephemeroptera), stoneflys (Plecoptera), and dragonflys Odonata , provide a significant food source for fish, amphibians and reptiles of this community. Four fish species, pirate perch (Aphredoderus sayanus), green sunfish Le omis cyanellus), tesselated darter (Etheostoma olmstedii), and shiner Notro is sp.), were captured during stream survey. Other species likely to be present in Upper Little River include yellow bullhead (Ictalurus natalis , largemouth bass (Micropterus salmoides), American eel (Anguilla rostrata , and pumpkinseed Le omis ibbosus . Various reptiles and amphibians are major components of the aquatic ecosystem, including pickeral frog Rana palustris), bullfrog catesbeiana), northern watersnake Nerodia si edon , snapping turtle Chel dra serpentina), and yellowbelly slider (Chr_ysemys scri to . Most of these species are largely aquatic but may venture out of the water to bask, feed, or travel to other habitats. Project construction will result in clearing and degradation of portions of the three terrestrial community types described. The estimated loss to these communities by construction of Recommended Alternate 1 is listed in the table below. It should be noted that estimated impacts were derived using the entire proposed right of way (80-foot impact width). Project construction often does not require the entire right of way and, therefore, actual impacts may be considerably less. TERRESTRIAL IMPACTS Biotic Community Steep Mesic Hardwood Slope Bottomland Hardwood Maintained TOTAL Approximate Impact 0.3 acre 0.4 acre 0.8 acre 1.5 acres The plant communities found along the project alignment serve as shelter, nesting and foraging habitat for numerous species of wildlife. Loss of habitat is likely to reduce the number of faunal organisms, and concentrate them into a smaller area, which causes some species to become more susceptible to disease, predation, and starvation. Individual mortalities during construction, are likely to occur to animals closely associated with the ground (snakes, small mammals, etc.). Mobile species will be displaced during construction activity. These animals may return to the area following construction; however, the amount of 11 forested habitat, will be reduced even further. Replacement of the bridge at is existing location will disrupt the least amount of terrestrial community of all of the alternates studied. Anticipated impacts to the Upper Little River stream community can be attributed to construction-related habitat disturbance and sedimentation. The aquatic environment serves as a major food source for many terrestrial organisms such as raccoons, various species of snakes, birds, turtles and amphibians. It also serves as a means of predator avoidance for amphibians (frogs and salamanders), reptiles (snakes and turtles), and mammals (muskrat and mink). Benthic non-mobile organisms, such as filter and deposit feeders, and macro-and-micro alga, are particularly sensitive to construction activities such as dredging, filling, pile driving operations, and slope stabilization. These construction activities physically disturb the substrate, resulting in loss of sessile benthic organisms. Many of these aquatic organisms are slow to recover, or repopulate an area because they require a stabilized substrate for attachment. Substrate stability may take a long time to develop; therefore, changes in community composition may occur. Populations of photosynthetic species, the primary producers in the food chain, can be greatly effected by siltation. The increased amount of suspended particles in the water column reduces the photosynthetic ability by absorbing available light. Clogging of feeding apparati of suspension feeders and burial of newly settled larvae of these organisms are other effects of siltation. These species are often primary consumers in the food chain and are a major step in the aquatic food web. Impacts to these organisms may directly effect organisms higher in the food chain, such as fish, amphibians, reptiles, birds, and mammals. Mobile aquatic organisms may escape some of the effects of siltation; however, gills of fish, crustaceans and larval amphibian and insect forms can become clogged and dysfunctional as a result of sedimentation. Spawning habitats for these mobile species may become filled with sediment, diminishing reproductive success and inevitably reducing populations. Habitat disturbance and sedimentation are extremely detrimental to aquatic ecosystems. Best Management Practices for protection of surface waters, will be strictly enforced to ensure the biological integrity of the water bodies impacted by this project. Measures will be taken to reduce the amount of probable increased concentrations of toxic compounds (gasoline, oil, etc.) in the stream coming from construction related machinery and road paving activities. Wetlands and surface waters fall under the broad category of "Waters of the United States" as defined in 33 CFR 328.3, in accordance with provisions of Section 404 of the Clean Water Act (33 U.S. C. 1344). Portions of the Bottomland Hardwood Forest qualify as jurisdictional wetlands. These are associated with the overflow floodplain of the Upper Little River. These wetlands are classified as Palustrine Forested, Broad-leaved Deciduous, Temporarily Flooded (PFOIA) as defined by Cowardin et al. (1979). Wetland impacts are estimated to be 0.09 acre for Recommended Alternate 1. The other alternates studied in conjunction with this project impact more wetlands than the recommended alternate. 12 Impacts to Waters of the United States fall under the jurisdiction of the U.S. Army Corps of Engineers (COE). A Nationwide permit 33 CFR 330.5 (A)23, for impacts to surface waters of Upper Little River,'is likely to be applicable. This permit authorizes activities undertaken, assisted, authorized, regulated, funded or financed in whole, or in part, by another Federal agency or department. That agency or department has determined that the activity is categorically excluded from environmental documentation, because it will neither individually or cumulatively have a significant d environmental effect. A North Carolina Division of Environmental Management (DEM) Section 401 (1665) Water Quality General Certification is also required, prior to issuance of the Nationwide permit. Projects authorized under Nationwide Permits usually do not require compensatory mitigation according to the 1989 Memorandum Agreement between the Environmental Protection Agency and the Department of the Army. Federal law requires that any action, which has the potential to jeopardize the continued existence of any species classified as federally protected, is subject to review by the U. S. Fish and Wildlife Service and/or the National Marine Fisheries Service under the provisions of the Endangered Species Act (ESA) of 1973, as amended. Rare species receive additional protection under separate state statutes. In North Carolina protection of plant species falls under N.C. General statutes (G.S.) 106-202.12 to 106-202.19 of 1979. Wildlife protection falls under G.S. 113-331 to 113-337. of 1987. Plants and Animals with federal classifications 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. As of March 30, 1994 the U. S. Fish and Wildlife Service lists two Endangered species, the red-cockaded woodpecker Picoides borealis and the Cape Fear shiner Notro is mekistocholas) for Harnett County. A brief description of these species characteristics and habitat requirements is provided, along with a biological conclusion which addresses the potential impacts to these species from the proposed project. The Cape Fear Shiner Notro is mekistocholas) was listed on September 26, 1987. The Cape Fear shiner has the most limited range of all Notropis species, and is restricted to the Cape Fear River basin, near the fall line. The Cape Fear shiner is a small, moderately stocky minnow that rarely exceeds 5 centimeters in length. Its body is pale silvery yellow, with a black band running along its sides. The fins are yellowish and . somewhat pointed. The upperlip is black and the lower lip has a black bar along its margin. It is easily distinguished from other similar species by having an elongated digestive tract to accommodate its diet of plant material. Cape Fear shiner habitat occurs in large streams and small to medium sized rivers. Preferred habitat is wide shallow sections of streams, with gravel, cobble, or boulder substrates. It is most often observed inhabiting slow pools, riffles, and slow runs associated with water willow beds. Juveniles can be found inhabiting slack-water, among large rock outcrops and in flooded side channels and pools. The Upper Little River does not offer suitable habitat for this species. Therefore, construction of this project will not adversely impact this species. 13 The red-cockaded woodpecker Picoides borealis was listed on October 13, 1970. The adult red cockaded woodpecker's (RCW) plumage is entirely black and white except for small red streaks on the sides of the nape in the male. The back is black and white with horizontal stripes and the breast and underside are white with streaked flanks. There is a large white cheek patch surrounded by the black cap, nape, and throat. RCW's use open old growth stands of southern pines, particularly longleaf pine for foraging and nesting habitat. A forested stand must contain at least 50% pine. These birds nest exclusively in trees that are > 60 years old and are contiguous with pine stands at least 30 years of age. The foraging area of the RCW can be as large as 500 acres, and this acreage must be contiguous with suitable nesting sites. These woodpeckers nest exclusively in living pine trees and usually in trees that are infected with the fungus that causes red-heart disease. Cavities are located in colonies from 12 to 100 feet above the ground and average 30 to 50 feet high. They can be identified by a large incrustation of running sap that surrounds the tree, which is referred to as "candle-sticking". This is arguably used as a defense against possible predators. A clan of woodpeckers usually consists of one breeding pair and the offspring from previous years. The eggs are laid in April, May, and June and hatch 38 days later. Clutch size is from 3-5 eggs. All members of the clan share in raising the young. RCWs feed mainly on insects but may feed on seasonal wild fruits. No pine dominated stands will be impacted by the proposed project. Therefore, construction of this project will have no effect on the red-cockaded woodpecker. There are a total of thirteen federal candidate (C2) species listed for Harnett County (see table below). Candidate 2 (C2) species are defined as taxa for which there is some evidence of vulnerability, but for which there are not enough data to warrant a listing of Endangered, Threatened, Proposed Endangered, or Proposed Threatened at this time. The North Carolina status of these Federal Candidate species is also listed in the table below. Plants or animals with state designations of Endangered (E), Threatened (T), or Special Concern (SC) are given protection by the State Endangered Species Act and the N. C. Plant Protection and Conservation Act of 1979, administered and enforced by the North Carolina Wildlife Resources Commission and the North Carolina Department of Agriculture respectively. Species with state designations of Candidate (C), Significantly Rare (SR) and Watch List (W) are not protected under state laws, but there is evidence of declining populations. These species are mentioned here for information purposes in the event ` that they become protected in the future. Specific surveys for these species were not conducted during site visits, nor were any of them observed during field reconnaissance. 14 Federal Candidate Species Harnett County NC Scientific Name Common Name Habitat Status Lampsilis cariosa Amorpha georgiana georgiana Astragalus michauxii Eupatorium resinosum Nestronia umbellula Oxypolis ternata Parnassia caroliniana Parthenium radfordii Pyxidanthera barbulata var. brevifolia Rudbeckia heliopsidis Solidago verna Stylisma pickeringii var. pickeringii Tofieldia lg abra yellow lampmussel N T Georgia leadplant N E sandhills milkvetch N C pine barrens boneset N C nestronia Y SR savanna cowbane N W Carolina grass-of- parnassus N E wavyleaf wild quinine N W Well's sandhill pixie moss N E sun-facing coneflower N E spring-flowering goldenrod N E Pickering's morning glory Y E smooth bog asphodel N C NC Status: . T and E denote Threatened and Endangered, respectively. C, SR, and W denote Candidate, Significantly Rare, and Watch, which are not Protected by state laws. A search of the NC-NHP data base of rare plants and animals resulted in no records of state or federally protected species in the project area. This project is located in the Sandhills Air Quality Region. The ambient air quality for Harnett County has been determined to be in compliance with the National Ambient Air Quality Standards. This project is not anticipated to create any adverse effect on air quality of this attainment area. This project will not substantially increase traffic volumes. Therefore, its impact on noise levels and air quality will be insignificant. 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 and laws and regulations of the North Carolina State Implementation Plans for air quality in compliance with 15 NCAC 2D.0520. Harnett County is a participant in the National Flood Insurance Regular Program. The approximate 100-year floodplain in the project area is shown in Figure 4. This location is beyond the limit of the detailed flood study; therefore, no regulatory floodway has been established in this area. The floodplain is rural and wooded in the vicinity of the project, and the proposed bridge replacement will not have a detrimental effect on the existing floodplain. f 15 Existing drainage patterns and groundwater will not be affected by the proposed bridge replacement. Although there does not appear to be evidence of significant scour potential with the sharp curve in the river at this crossing warrants that careful design consideration be given to protecting the banks from erosion scour. Aside from that, standard erosion and sedimentation control devices and measures should be adequate, provided they are properly installed and maintained. On the basis of the above discussion, it is concluded that no serious adverse environmental effects will result from implementation of the project.

On June 10, 1992, Robin Stancil of our staff met with North Carolina Department of Transportation (NCDOT) staff for a meeting of the minds concerning the above project. We reported our available information on historic architectural and archaeological surveys and resources along with our recommendations. NCDOT provided project area photographs and aerial photographs at the meeting and for our use afterwards. Based upon our review of the photographs and the information discussed at the meeting, we offer our preliminary comments regarding this project. In terms of historic architectural resources, we are aware of no historic structures located within the area of potential effect. We recommend that no historic architectural survey be conducted for this project. We are unable to assess the effects of the proposed bridge replacement upon archaeological resources until specific information concerning the location of the new bridge and detour structures is available. Please forward this information to us as soon as possible so we can complete our review. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which ind' addressed our concerns.

Glover of North Carolina Department of Transportation concerning the above project. During the course of the survey no prehistoric or historic archaeological sites were located within the project area. Due to the lack of cultural resources, Mr. Glover has recommended that no further archaeological investigation be conducted in connection with this project. We concur with this recommendation since this project will not involve significant archaeological resources.
