BOX 1890 WILMINGTON, NORTH CAROLINA 28402-1890 September 23, 1993 IN HhPLY HtlttH IU Regulatory Branch, Action ID. 199304486 and Nationwide Permit No. 23 (Approved Categorical Exclusions) Mr. L. J. Ward Planning & Environmental Branch N.C. t..afTransportation Post O ice Box 25201 Raleigh, North Carolina 27611 Dear Mr. Ward: Reference is made to your letter of August 30, 1993, regarding your plans to discharge dredged/fill material into the waters/wetlands of the South Fork New River, associated with the replacement o 6-_#6: ' 1 12y SR 1181, located north of Idlewild,-Mhe County, North Carolina,OTIP No. B-2107. Plans included with your letter showed that you propose to replace the aforementioned bridge with a new bridge to the west of the existing bridge, and that the existing bridge will be removed when the new route is completed. Reference is also made to Mr. Stephanie Goudreau's letter of March 5, 1993, in which the North Carolina Wildlife Resources Commission expressed no objections to the planned road improvements provided that: a. No heavy equipment is operated in the live streams in order to minimize sedimentation and prevent introduction of other pollutants, and b. Erosion control measures should be implemented where `soil is disturbed and maintained until project completion. c. Construction must be accomplished so that wet concrete does not contact stream water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill. d. Temporary ground cover (e.g. hardwood mulch, straw, etc.) must be placed on all bare soil during construction. Permanent vegetation in these- same areas must be established within 15 days of ground-disturbing activities to provide long term erosion control. For the purposes of the U.S. Army Corps of Engineers' Regulatory Program, Title 33, Code of Federal-Regulations (CFR), Part 330.6, published in the Federal Register on November 22, 1991, lists nationwide permits (NWP). Authorization, pursuant to Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act, was provided for activities -2- undertaken, assisted, authorized, regulated, funded or financed, in whole or in part, by another Federal agency or department where that agency,or department has determined, pursuant to the CEQ Regulation for the Implementing the Procedural Provisions of the National Environmental Policy Act, that the activity, work or discharge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and the office of the Chief of Engineers has been furnished notice of the agency's or department's application for the categorical exclusion and concurs with that determination. Your work is authorized by this NWP provided it is accomplished in strict accordance with the enclosed conditions-and provided you receive a Section 401 water quality certification from the North Carolina Division of Environmental Management (NCDEM) and, in the coastal area, a consistency determination from the North Carolina Division of Coastal Management (NCDCM). You should-contact Mr. John Dorney, telephone (919) 733-1786, regarding water quality certification, and Mr. Steve Benton, telephone (919) 733-2293, regarding consistency determination. This NWP does not relieve you of the responsibility to obtain other required State or local approval. Special regional conditions of this NWP state that before discharging dredged or fill material into waters of the United States occurring within the 25 mountain counties of North Carolina that contain trout waters, the applicant will obtain a letter of approval from the North Carolina Wildlife Resource Commission. Review of the information you have provided, and the comments submitted by the North Carolina Wildlife Resources Commission, reveals that your proposed work, is authorized by NWP provided it is accomplished in strict accordance with the enclosed conditions and the recommendations set forth by the Wildlife Resources Commission. This NWP does not relieve you of the responsibility to obtain any required State or local approval. This verification will be valid for 2 years from the date of this letter unless the nationwide authorization is modified, reissued or revoked. Also, this verification will remain valid for the 2 years if, during that period, the NWP authorization is reissued without modification or the activity complies with any subsequent modification of the NWP authorization. If during the 2 years, the NWP authorization expires or is suspended or revoked, or is modified, such that the activity would no longer comply with the terms and conditions of the NWP, activities which have commenced (i.e., are under -3- construction) or are under contract to commence in reliance upon the NWP will remain authorized provided the activity is completed within 12 months of the date of the NWP's expiration, modification or revocation, unless discretionary authority has been exercised on a case-by-case basis to modify, suspend or revoke the authorization. Thank you for your time and cooperation. If you have any questions, please contact Mr. John Thomas, Raleigh Regulatory Field Office, telephone (919) 876-8441. Sincerely, G.

SUMMARY OF PROJECT Bridge No. 12 crosses the South Fork New River in Ashe County. The 1993-1999 Transportation Improvement Program (TIP) includes Bridge No. 12 as a bridge replacement project. The project is classified as a Federal Categorical Exclusion. No substantial environmental impacts are expected. Bridge No. 12 will be replaced on new alignment to the north of the existing bridge, shown as Alternate lA in Figure 2a. The recommended replacement structure is a bridge approximately 230 feet long and 24 feet wide. The bridge will provide a 20-foot wide travelway plus a 2-foot wide offset on each side. Approximately 1,200 feet of new approach roadway will improve the horizontal alignment, providing a 30 mph design speed. The new roadway will have a 20-foot wide pavement plus 4-foot graded shoulders. It will be at approximately the same grade as the existing roadway. Traffic will be maintained on the existing bridge during construction. The estimated cost is $618,000. The estimated cost shown in the 1993-1999 TIP is $300,000. II. SUMMARY OF ENVIRONMENTAL COMMITMENTS All standard procedures and measures will be implemented to avoid or minimize environmental impacts. High Quality Water Zone design standards will be implemented for this project. Best management practices and Sedimentation Control guidelines will be implemented prior to construction and throughout the duration of the project. Non-point sediment sources will be identified and efforts will be made to control sediment runoff. The existing roadway will be removed, graded to surrounding conditions, and planted with native vegetation. The population of the federally endangered Virginia Spiraea will be marked by NCDOT environmental biologists. No grading, filling, or other earth-disturbing activities will be constructed within 50 feet of this population. III. EXISTING CONDITIONS The Statewide Functional Classification System classifies SR 1181 as a rural local route. Near Bridge No. 12, SR 1181 has a 12-foot wide travelway plus four-foot grass shoulders. Vertical alignment is poor. Horizontal alignment is also poor, because of a near 90-degree turn at the western end of the bridge and another sharp turn just east of the bridge.. The bridge deck is 20 feet above stream bottom. Traffic projections are 200 VPD for 1995 (the proposed construction year) and 400 VPD for 2015. Truck percentages are 11. truck-tractor semi=trailer (TTST) and 2% dual-tired. Constructed in 1958, the existing bridge has a timber deck on steel. girder floor beams, reinforced concrete (RC) abutments, and RC internal piers. Total length is 135 feet with a clear roadway width of 11 feet. Bridge No. 12 carries one lane of traffic and has a posted load limit of 9 tons. According to Bridge Maintenance Department records, the sufficiency rating is 17.2 of a possible 100.0. The estimated remaining life is less than five years. The Traffic Engineering Branch records no accidents at the bridge between 1 February 1989 and 31 January 1992. The Transportation Director for Ashe County Schools reported two school bus crossings daily. IV. ALTERNATIVES There are four alternatives for replacing Bridge No. 12. Alternate 1 would replace the existing bridge on a skewed crossing north of the existing alignment. The recommended structure is a bridge approximately 230 feet long, and 24 feet wide. The bridge will provide a 20-foot wide travelway with a 2-foot offset on each side. This alternate would require approximately 500 feet of new approach roadway and allow traffic to be maintained on the existing bridge during construction. When completed, this alternate would provide a 20 mph design speed. Alternate lA (Recommended) will replace the existing bridge as in Alternate 1, but will more extensively realign SR 1181 north of the bridge to provide a 30 MPH design speed. Approximately 1,200 feet of new approach roadway will be required. Alternate 2 would replace the existing bridge at the existing location. The recommended structure would be a bridge approximately 190 feet long and 24 feet wide. It would provide a 20-foot wide travelway with a 2-foot offset on each side. Traffic would be maintained on a temporary, 130-foot long on-site detour bridge south of the existing alignment. When completed, this alternate would provide a 20 mph design speed. Alternate 3 would replace the existing location. The recommended structure would be feet long and 24 feet wide. It would provide with a 2-foot offset on each side. Traffic existing secondary roads during construction. alternate would provide a 20 mph design speed. bridge at the existing a bridge approximately 190 a 20-foot wide travelway would be maintained on When completed, this w 2 The "do-nothing" alternate is not practical. It would require eventually closing the road or applying extremely high maintenance due to excessive deterioration and functional obsolescence of the bridge. V. COST ESTIMATES Table 1 is a list of construction and right of way costs for the studied alternates. Table 1.

RECOMMENDED IMPROVEMENTS Bridge No. 12 will be replaced north of the existing alignment as shown in Alternate 1A, Figure 2a. This alignment will provide a 30 MPH design speed. Traffic should be maintained on the existing bridge during construction. The recommended replacement structure is a bridge approximately 230 feet long and 24 feet wide. According to a preliminary hydraulics investigation, this should be adequate to handle flow from the South Fork New River. This size may be changed if required by further hydrologic studies. The roadway approaches will have a 20-foot wide travelway plus 4-foot graded shoulders. After construction of the new bridge and roadway approaches is completed and opened to traffic, the existing bridge will be removed. The existing roadbed of SR 1181 from just west of the existing bridge to point A of Figure 2a will be taken off the state system, but left in place to 3 provide access for the two driveways presently intersecting SR 1181.. From point A north to point B, the existing roadbed will be removed in accordance with the environmental commitments. The NCDOT is considering retaining the right of way and existing roadbed on the southeast side of the existing bridge. This will allow parking and access for a canoe and small boat launch that the North Carolina Wildlife Resources is interested in constructing and maintaining. Although none of the studied alternates provides a desirable design speed, the recommended alternate has the best alignment and highest design speed. Although the estimated cost is $38,000 higher than Alternate 1, the additional expense is justified by the higher design speed. In addition, the alignment of Alternate 1A is farther from the river bed. The alignment approaching Alternate 1 is very close to the river, resulting in more erosion potential and higher future maintenance costs. Alternate 2 was eliminated because it has the highest estimated cost, does not improve the design speed, and the alignment remains close to the river. Alternate 3 was eliminated because road closure would result, it does not improve the design speed, and the alignment remains close to the river. Road closure is not recommended due to a lack of paved detour routes and the high flood potential along available detour routes. The NCDOT Division 11 Engineer concurs with Alternate 1A noting the improved design speed and reduced maintenance. VII. ENVIRONMENTAL CHARACTERISTICS AND EFFECTS A. Background The project is in a rural setting southwest of Glendale Springs in Ashe County. It is in the Mountain Physiographic Province. Most of the study area is pasture. Topography in the area ranges from gently to strongly sloping. Elevation is approximately 2,800 feet above mean sea level. B. Plant Communities Three upland plant community types were identified in the study area: Disturbed, Mixed Hardwood, Riparian Fringe. One type of wetland plant community was identified in the study area: Disturbed Palustrine. Actively used pasture is above the Riparian fringe community along stretches east and west of the river. Canopy and shrub layers are absent. The herb layer includes species such as Queen Anne's lace, Joe-pye-weed, spiderwort, and red clover. A ground cover of poison ivy is present, but sparse. Mixed hardwoods dominate a narrow portion of the study area in the northwest and southwest quadrants of the existing bridge site. This area is strongly sloping and exposed bedrock is visible in spots. Dominant canopy vegetation includes red maple, black locust, and northern red oak. 4 Beneath the canopy is a dense shrub layer consisting of rosebay. Herbs are sparse and present primarily where the Mixed Hardwood community. borders the Disturbed community. Red oak seedlings are present. The Riparian Fringe community is along the banks of the South Fork New River. This community periodically floods. Elderberry, dogwood, and tag alder are dominant. Two locations of Disturbed Palustrine wetland plant community are in the study area. A small stream supports a small wetland in the northeast part of the project area. This community is adjacent to the Disturbed community described above and supports only a herbaceous layer. Rush, duck-potato, and knotweed are dominant. A second stream supports a small wetland west of SR 1181. Construction will impact the Disturbed, Mixed Hardwood, Riparian Fringe, and Disturbed Palustrine communities. Table 2 lists plant community impacts. These estimates are preliminary and may change with final design. Table 2.

Wildlife Communities Mammals anticipated in the study area include deer mouse, eastern chipmunk, woodchuck, and white-tailed deer. Birds likely to inhabit the study area are house finch, starling, red-tailed hawk, American kestrel, bobwhite, brown-headed cowbird, common crow, common grackle, Cooper's hawk, eastern meadowlark, field sparrow, mourning dove, and turkey vulture. Amphibians and reptiles common in the study area include American toad, Fowler's toad, slimy salamander, Jordon's salamander, eastern garter snake, eastern fence lizard, timber rattlesnake, rat snake, brown snake, redbelly snake, and eastern box turtle. . Fish common in the South Fork New River and possibly found in the study area include brook trout, central stoneroller, rosyside dace, blacknose dace, longnose dace, bigmouth chub, creek chub, northern hog sucker, smallmouth bass, several darters, various shiners, and mottle sculpin. According to the North Carolina Natural Heritage Program (NCNHP), near the project the New River supports a high diversity of aquatic organisms. Fish recorded in the project vicinity include Kanawha minnow Phenacobius teretulus) and sharpnose darter (Percina oxyrhychus). Neither of these species are federally protected (Candidate status and no federal status respectively) but both have a state status of Proposed Special Concern. Another aquatic organism found in the project area is the riffle beetle (Stenelmis ammoni), which is federally listed as a C2 or Candidate species and has state status of Significantly Rare. D. Soils Soil information comes from the Ashe County Soil Survey (Soil Conservation Service, 1985). One soil mapping unit is in the study area - Colvard fine sandy loam. This map unit is a soil unit with Hydric Inclusions. Colvard fine sandy loam formed in recent alluvium and is on nearly level floodplains of major streams. This map unit is well drained. E. Water Quality The project is in the New River Basin, and crosses the South Fork New River. The South Fork New River is approximately 120' wide and several feet deep. The bottom is sand, silt, and boulders with small amounts of cobble and gravel sized materials. The South Fork New River originates southwest of the study area and flows to the northeast. It joins the North Fork New River to become the New River. Best use classification of the South Fork New River is WS-IV HQW (DEM, 1993). WS-IV waters are protected as water supplies that are generally in moderately to highly developed watersheds - point source discharges of treated wastewater are permitted pursuant to several rules stated in subchapters .0104 and .0211, local programs to control non-point source and stormwater discharge of pollution are required, and WS-IV waters are suitable for all class C uses. Class C is defined as aquatic life propagation and survival, fishing, wildlife, secondary recreation, and agriculture. HQW (High Quality Waters) is a supplemental classification indicating a water rated as excellent based on biological and physical chemical characteristics through division monitoring or special studies. There are three stream crossings in the project area. These streams are unnamed and unclassified. The best use classification of these streams is the same as the river to which they are tributaries, the South Fork New River, which is WS-IV. Since the New River is a HQW, the proposed project is in a "High Quality Water Zone," which is defined as areas within one mile and draining into a HQW. Construction that impacts a "High Quality Water Zone" is required to follow Design Standards in Sensitive Watersheds in the Sedimentation Control Guidelines (Title 15A. 4B. 0024). The South Fork New River is currently proposed for reclassification to an Outstanding Resource Water (ORW). Efforts will be made to plan project under the assumption that the New River will be designated as an ORW. Proposed construction in a freshwater ORW follows the same 6 restrictions as a HQW for stormwater controls and follows management components as stated in the Administrative Code Section for the Classifications and Water Quality Standards Applicable to Surface Waters of North Carolina Rule 15A NCAC 2B .0216 (Environmental Management Commission, 1991) The Benthic Macroinvertebrate Ambient Network (BMAN) is part of an ongoing ambient water quality monitoring program. This network addresses long term trends in water quality by measuring the taxa richness and presence of organisms intolerable to changes in water quality. These organisms are sensitive to subtle changes in water quality. No BMAN surveys have been conducted in the South Fork New River near the project. High Quality Water Zone design standards will be followed. Sedimentation Control guidelines and Best Management Practices will be implemented prior to construction and maintained throughout the life of the project. Non-point sediment sources will be identified and efforts made to control sediment runoff. F. Waters of the U.S. The Corps of Engineers is responsible for regulating activities in "Waters of the U.S." based on the following laws: Section 10 of the Rivers and Harbors Act of 1899 (33 USC 403), Section 404 of the Clean Water Act (33 USC 1344) and Section 103 of the Marine Protection, Research and Sanctuaries Act of 1972, as amended (33 USC 1413). Any action that proposes to impact "Waters of the U.S." falls under the jurisdiction of the Corps of Engineers and a federal permit is required. Generally, "Waters of the U.S." are defined as navigable waters, their tributaries and associated wetlands and subdivided into "wetlands" and "surface waters." Jurisdictional wetlands, as defined by 33 CFR 328.3, are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted to life in saturated conditions. Criteria for wetland determinations are described in the "Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory, 1987). Any action that proposes to place fill into these areas falls under the jurisdiction of the US Army Corps of Engineers under the Provisions of the Clean Water Act (33 USC 1344). Surface waters and wetlands are two subsets of "Waters of the U.S." Impacts to "Waters of the U.S." are anticipated from proposed construction, including approximately 0.2 acres of jurisdictional wetlands. The proposed project will impact "surface waters" of the South Fork New River and a jurisdictional wetland plant community located in the study area. Observations of vegetation, soils, and hydrology determined Jurisdictional wetland boundaries. The vegetation is hydrophytic and the soil color is hydric. 7 G. Permits Because the project is classified as a Categorical Exclusion, a Nationwide Permit 33 CFR 330.5(a)(23) will be applicable for proposed construction. This permit authorizes any activities undertaken, assisted, authorized, regulated, funded, or financed, in whole or in part, by another federal agency or department as determined pursuant to the Council on Environmental Quality regulation for implementing the procedural provisions of the National Environmental Policy Act, that the activity, work, or discharge is Categorically Excluded from environmental documentation because it is included within a category of actions., which neither individually or cumulatively have a significant effect on the human environment and the Corps of Engineers' office of the Chief of Engineers has been furnished notice of the agency's or department's application for the CE and concurs with that determination. In addition, the project is in Ashe County, a designated "trout" county where NCDOT is required to obtain a letter of approval from the North Carolina Wildlife Resources Commission (NCWRC). The South Fork New River is not classified as a Designated. Public Mountain Trout Water, therefore the NCWRC has no objection to this project. The NCWRC is interested in increasing angler accessibility to the river. NCWRC requests that NCDOT examine the feasibility of retaining right-of-way to allow room for anglers to park vehicles off the side of the roadway near the project. If NCDOT provides this, the NCWRC can construct a canoe ramp in the river where anglers can launch car-top boats. The NCDOT Division 11 Engineer indicated the existing R/W and road bed on the southeast side of Bridge No. 12 would provide an excellent area for cars to park, and the NCWRC could build a canoe ramp on this side. Final consideration of this will be given during the design phase of the project. A Section 401 General Water Quality Certification is required for any activity that may result in a discharge and for which a federal permit is required. State permits are administered through the Department of Environment, Health, and Natural Resources (DEHNR). Construction will be authorized under a Nationwide Permit. Generally, no mitigation is required according to the MOA between the Corps of Engineers and the Environmental Protection Agency (1989). The final decision rests with the Corps of Engineers. H. Protected Species Four federally protected species are listed by the USFWS in Ashe County as of March 4, 1993. These species are in Table 3. Table 3. Federally Protected Species Listed for Ashe County COMMON NAME Spreading avens Roan Mountain bluet Heller's blazing star Virginia spiraea SCIENTIFIC NAME STATUS Geum radiatum E Hedyoutis ur urea var. montana E Liatris helleri T Spiraea virginiana T E - Endangered T - Threatened 8 Spreading avens occurs on scarps, bluffs, cliffs and escarpments on mountains, hills, and ridges. Habitat requirements for this species include full sunlight, high elevations, and shallow acidic soils. The spreading avens is found in soils composed of sand, pebbles, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. The study area does not support suitable habitat for spreading avens. No impacts to spreading avens will occur from proposed construction. Roan Mountain bluet can be found on high elevation cliffs, outcrops, steep slopes, and in the gravel talus associated with cliffs. It grows best in areas exposed to full sunlight and in shallow acidic soils composed of various igneous, metamorphic, and metasedimentary rocks. The study area does not support suitable habitat for Roan Mountain bluet. No impacts to Roan Mountain bluet will occur from proposed construction. Heller's blazing star is a high altitude early pioneer species and can be found growing on high elevation ledges of rock outcrops in grassy areas exposed to full sunlight. It prefers shallow acid soils associated with granite rocks. The study area does not support suitable habitat for Heller's blazing star. No impacts to Heller's blazing star will occur from proposed construction. Virginia spiraea is found in a very narrow range of habitats consisting of scoured banks of high gradient streams, on meander scrolls, point bars, natural levees, or braided features of lower reaches. The scour must be sufficient to prevent canopy closure, but not extreme enough to completely remove small woody species. This species occurs in the maximum floodplain, usually at the water's edge with various other disturbance-dependent species. It is most successful in areas with full sunlight, but can survive in shaded areas until it is released from competition. The study area supports suitable habitat for Virginia spiraea along the banks of the South Fork New River. The east and west banks of the river were surveyed by walking on land and in the water along the entire length of the project. A population of Virginia spiraea was found on the western bank of the river, approximately 0.1 mile north of the existing bridge. Removal of the existing pavement will be confined to the existing pavement width to protect the Virginia Spiraea population (see Figure 5). The environmental commitments specified on page 3 will prevent adverse effects to the Virginia Spiraea. The U.S. Fish and Wildlife Service has concurred with this finding. A copy of this concurrence is included in the appendix. I. Farmland The Farmland Protection Policy Act requires all federal agencies, or their representatives, to consider the impact of land acquisition and construction projects on prime and important farmland soils. These soils are determined by the US Soil Conservation Service (SCS) based on criteria evaluating crop yield and level of input of economic resources. NCDOT asked the SCS to review whether the proposed bridge replacement project will impact important farmland soils. Their review shows that approximately 1.3 acres of prime farmland soils will be affected. 9 The prime farmland affected by the project has the highest relative value of 100 points on the Land Evaluation Criterion scale of 0 to 100. According to the SCS, only two percent of the farmland in Ashe County has the same or higher relative value. The total site assessment score for the conversion of farmland was 173 of a possible 260 points. The Department of Agriculture has established a threshold of 160 points as the level at which alternatives or mitigation measures should be considered. After construction, portions of the existing roadway will be removed, and the resulting land can be used for farming. Therefore, the actual impacts to prime farmland soils are reduced, and no additional mitigation measures will be considered. J. Wild and Scenic Rivers The Wild and Scenic Rivers Act of 1978, as amended, declared it the policy of the United States to preserve certain selected rivers, "which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic cultural, or other similar values" (16 U.S.C. 1271 et seq.). The act established the Wild and Scenic River System. The segment of the South Fork New River including the project area is listed in the Nationwide Rivers Inventory, a register of rivers under consideration for designation to the Wild and Scenic River System. It was determined that the bridge project will not have an adverse effect on the South Fork New River, nor will it result in the foreclosure of options to classify it as a wild, scenic, or recreational river. K. Historic and Archaeological Resources In terms of historic architectural resources, there are no National Register-listed properties in the project area. The Jesse B. Miller House is in the project area. The house is not eligible for National Register listing because it is an altered example of a type prevalent throughout the state. Archaeological site number 31AH194 is near the bridge. A comprehensive archaeological survey was conducted to identify the presence and significance of archaeological remains in the project area. Site number 31AH194 is outside the project area and will not be affected by the project. No other archaeological sites will be affected by the project as presently proposed, and no further archaeological work will be required.

Sox 25201 Raleigh, North Carolina 27611-5201 Dear Mr_ Fedora: tt AMEPJCA "Nomm We received a copy of Ms. Susan Corda's memorandum of May 17, 1993, regarding potential effects to the federally threatened Virginia spiraea (Spiraea viroiniana) from the proposed replacement of Bridge Number 12 (Project B-2107) along S_R. 1181 over the South Fork New River in Ashe County, North CF-rolina. We nave reviewed the information provided in this memorandum and j r previous correspondence; the following coiranents are provided pursuant to Sect:on 7 of the Endangered Species Act CF 197-3, .as amended (16 U.S.C. 153--1543) (Act). Ms. Corda notified the U.S. Fish and Wildlife Service (Service) on August 17, 1992, about the discovery of a new population of Spiraea vir-giniana on the west. bank of the South Fork of the New River in Ashe County. This discovery was grade during routine field investigations for the proposed replacement. of Bridge Number 12. the S iraea viroiniana population reportedly is approximately 100 feet downstream of the proposed project. On April 15, 1993, the Service received information from you with regard to project alternatives and environmental commitments and was asked to provide comments on potential impacts, to the Spiraea virginiana population. Ms. Janice Nicholls of our staff contacted Ms. Cord-r, to explain that it would be more appropriate for the North Carolina Department of Transportation to make a determination of effect on the Sniraea virginiana population first and that the Service's comments would follow- Eased on the five environmental commitments outlined in Ms. Corda's May 17, 1993, memorandum and other information available to this office, the Service concurs.with the finding that the proposed bridge replacement activity is not likely to adv rsely affect Spiraea_ virginiana. in view of this, the Service believes the requirements of Section 7(c) of the Ar are fulfilled. However, obl i get t ons u=nder Section 7 of the AcZ imust be reconsiLdered if: (1) new infar iation reveals impacts of this identified action that may of l ecl -listed spec 1 es i r? a manner not prey I ously considered, (2) this acLi on is subsequently modified -in a mariner not. considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. We appreciate the Department of Transportation's continued commitment to protect federaTly listed endangered and threatened species. Please do not hesitate to contact ids. Nicholls at 704/665-1195, Ext. 227, if you have any further questions. In any future correspondence pertaining to this project, please reference our Log Number 4-2-93-073. Sincerely, -Brian P. Cole.

Fullwood, Executive Director MEMORANDUM TO: Wayne Fedora, Planning & Environmental Branch North Carolina Department of Transportation FROM: Stephanie Goudreau, Mt. Region oordinator? Habitat Conservation Program DATE: March 5, 1993 SUBJECT: Scoping comments for replacement of Bridge #12 on SR 1181 over South Fork New River, Ashe County (Federal Project'#BRZ-1181(3), State Project #8.2710501, TIP #B- 2107) This correspondence responds to a request by you for our scoping comments regarding the replacement of Bridge #12 on SR 1181 over the South Fork New River in Ashe County. The proposed replacement structure is a 230-foot long bridge with a 24-foot wide travelway to be constructed north of the existing bridge. The South Fork New River is not Designated Public Mountain Trout Water and does not support trout. Therefore, we have no objection to this project. The South Fork New River does support good populations of smallmouth bass and rock bass and is popular with anglers. The North Carolina Wildlife Resources Commission (NCWRC) is interested in increasing angler access to this river. We request that the NCDOT examine the feasibility of retaining right-of-way to allow room for anglers to park their vehicles off the side of the roadway near either the existing or new bridge. If the NCDOT can meet this need, the NCWRC could construct a canoe ramp in the river from which anglers could launch car-top boats. .Thank you for the opportunity to review and comment on this project. If you have any questions regarding these comments, please contact me at 704/652-4257. cc: Mr. Joe Mickey, District 7 Fisheries Biologist _ c. 5T_1TF `f r North Carolina Department of Cultural Resources James G.

Price, Jr., Director On April 15, 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. `r'+le 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 National Register-listed properties within the area of potential effect. For the two structures over fifty years of age within the area of potential effect, Site Nos. 1 and 2, we need additional information to determine National Register eligibility. Photographs which give more detail of Site No. 2 would be helpful. Also, does the land on the north side of the existing SR 1 181 (where the roadway will be realigned) belong to the owners of Site Nos. 1 and 2? Site number 31 AH 194 is (coated next to the bridge within the area of potential effect. We recommend that a comprehensive survey be conducted by an experienced archaeologist to identify the presence and significance of archaeological remains that may be damaged or destroyed by the proposed project. Potential effects on unknown resources should be assessed prior to the initiation of construction activities. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our concerns. 109 East Jones Street • Raleigh, North Carolina 27601-2807 .cholas L.

BOX 1890 WILMINGTON, NORTH CAROLINA 28402-1890 December 8, 1993 IN REPLY REFER TO Regulatory Branch Action ID No. 199304486 and Nationwide Permit No. 6 (Survey Activities) Mr. Frank Vick Planning & Environmental Branch N.C. Department of Transportation Post Office Box 25201 Raleigh, North Carolina 27611 Dear Mr. Vick: Reference is made to your letter of November 15, 1993, regarding your plans to discharge dredged/fill material into the waters/wetlands of South Fork New River, associated with foundation test borings included with the replacement of Bridge No. 12, SR 1181, located north of Idlewild, Ashe County, North Carolina, TIP No. B-2107. Reference is also made to Mr. Joe Mickey's letter of November 24, 1993, in which the North Carolina Wildlife Resources Commission expressed no objections to the aforementioned test borings. For the purposes of the U.S. Army Corps of Engineers' Regulatory Program, Title 33, Code of Federal Regulations (CFR), Part 330.6, published in the Federal Register on November 22, 1991, lists nationwide permits (NWP). Authorization, pursuant to Section 10 of the Rivers and Harbors Act of 1899 and Section 404 of the Clean Water Act, was provided for survey activities including core sampling, seismic exploratory operations and plugging of seismic shot holes and other exploratory-type bore holes. Special regional conditions of this NWP state that before discharging dredged or fill material into waters of the United States occurring within the twenty-five mountain counties of North Carolina that contain trout waters, the applicant will obtain a letter of approval from the North Carolina Wildlife Resource Commission (NCWRC). Review of the information you have provided, and the comments submitted by the NCWRC, reveals that your proposed work is authorized by NWP provided it is accomplished in strict accordance with the enclosed conditions and the recommendations set forth by the Wildlife Resources Commission. This NWP does not relieve you of the responsibility to obtain any required State or local approval. This verification will be valid for 2 years from the date of this letter unless the nationwide authorization is modified, reissued or revoked. Also, this verification will remain valid for the 2 years if, during that period, the NWP authorization is reissued without modification or the activity complies with any subsequent modification of the NWP authorization. If during -2- the 2 years, the NWP authorization expires or is suspended or revoked, or is modified, such that the activity would no longer comply with the terms and conditions of the NWP, activities which have commenced (i.e., are under construction) or are under contract to commence in reliance upon the NWP will remain authorized provided the activity is completed within 12 months of the date of the NWP's expiration, modification or revocation, unless discretionary authority has been exercised on a case-by-case basis to modify, suspend or revoke the authorization. Thank you for your time and cooperation. If you have any questions, please contact Mr. John Thomas, Raleigh Regulatory Field office, telephone (919) 876-8441. Sincerely, G.
