NORRIS TOLSON SECRETARY Attention: Mr. Steve Lund NCDOT Coordinator Subject: Avery County, Replacement of Bridge No. 65 over North Toe River or. SR 1117; Federal Aid Project No. BRZ-1117(2), State Project No. 8.2720701, TIP No. B-2916. Dear Sir: Attached for your information are copies of the programmatic categorical exclusion (CE) action classification form and the natural resources technical report for the subject project. The Department of Transportation (DOT) plans to replace Bridge No. 65 over North Toe River in Avery County on existing location. Bridge approaches will also be improved. During bridge replacement, traffic will be maintained off-site along existing secondary roads, as depicted in the programmatic CE. Based on the natural resources technical report prepared for the DOT, the proposed bridge replacement will not impact jurisdictional wetlands. Currently, Bridge No. 65 over North Toe River has a let schedule of December 1999. NCDOT has already received permission to conduct survey activities under Section 404 Nationwide 6 from the Corps of Engineers (COE) on October 02, 1998 (Action ID. No. 199831112) and a 401 Water Quality Certification by the Division of Water Quality on September 1, 1997 (DWQ No. 980859) and written concurrence from NCWRC on August 24, 1998. The following environmental commitments have been implemented into the referenced programmatic categorical exclusion (CE) action classification form that is attached for your reference. Because the North Toe River is Hatchery Supported Designated Public Mountain Trout Water in addition to supporting some wild rainbow and brown trout, the following will be implemented during construction: • Construction will be accomplished so that wet concrete does not contact river water. This will lessen the chance of altering the river's water chemistry and causing fish kills. • Where possible, heavy equipment will be operated from the bank rather than in the river channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the river. Temporary or permanent herbaceous vegetation will be planted on all bare soil within 15 days of the completion of ground disturbing activities to provide long term erosion control. The project is being processed by the Federal Highway Administration as a programmatic "Categorical Exclusion" in accordance with 23 CFR 771.115(b). Therefore, the DOT does not anticipate requesting a Section 404 Individual Permit, but proposes to proceed under a Section 404 Nationwide Permit in accordance with 33 CFR 330-Appendix-A (B-23) issued on December 13, -1596-by the Corps of Engineers. The provisions of Section 330.4 and Appendix A (C) of these regulations will be followed in the construction of the project. It is anticipated that a 401 Water Quality Certification for a Categorical Exclusion will apply to this project. A copy of the CE and natural resources technical report are being provided to the CE document to the North Carolina Department of Environment, Health and Natural Resources, Division of Water Quality (DWQ), for their review. The DOT requests a Section 404 Nationwide Permit 23 for impacts to waters of the United States from the proposed bridge replacement. Application for 401 Water Quality Certification from the DWQ is also made. { If you have any questions or need any additional information, please contact Mr. Jared Gray at (919) 733-7844, extension 329.

Project Description : The purpose of this project is to replace Bridge No. 65 on SR 1117 over the North Toe River in Avery County. The new structure will be a bridge 34 meters (111 feet) long with a minimum clear deck width of 7.2 meters (28 feet) including two 3.3-meter (11-foot) lanes and 1.0-meter (3-foot) offsets. The new bridge will be at the same location and elevation. Traffic will be detoured on secondary roads during construction (see Figure 1). There will be 91 meters (300 feet) of approach work to the east and 61 meters (200 feet) to the west. The pavement'width will include two 3.3-meter (11- foot) lanes and 1.2-meter (4-foot) grass shoulders. An additional 3 feet of shoulder will be included where guardrail is required. Based on preliminary design, the design speed should be approximately 100 km/h (60 mph). The estimated cost of the project is $555,000 including $500,000 in construction costs, and $55,000 in right of way costs. The estimated cost shown in the 1998- 2004 TIP is $355,000 including $325,000 in construction costs, and $30,000 in right of way costs. B. Purpose and Need: Bridge No. 65 has a sufficiency rating of 46.8 out of 100. The bridge is posted at 21 tons for single vehicles and 24 tons for truck-tractor semi-trailers which is well below standards. For these reasons, Bridge No. 65 needs to be replaced. r C: Proposed Improvements: Circle one or more of the following improvements which apply to the project: Type II Improvements 1. Modernization of a highway by resurfacing, restoration, rehabilitation, reconstruction, adding shoulders, or adding auxiliary lanes (e.g., parking weaving, turning, climbing). a. Restoring, Resurfacing, Rehabilitating, and Reconstructing pavement (3R and 4R improvements) b. Widening roadway and shoulders without adding through lanes c. Modernizing gore treatments d. Constructing lane improvements (merge, auxiliary, and turn lanes) e. Adding shoulder drains f. Replacing and rehabilitating culverts, inlets, and drainage pipes, including safety treatments g.

Approvals for disposal of excess right-of-way or for joint or limited use of right-of-way, where the proposed use does not have significant adverse impacts. 7. Approvals for changes in access control. 8. Construction of new bus storage and maintenance facilities in areas used predominantly for industrial or transportation purposes where such construction is not inconsistent with existing zoning and located on or near a street with adequate capacity to handle anticipated bus and support vehicle traffic. 9. Rehabilitation or reconstruction of existing rail and bus buildings and ancillary facilities where only minor amounts of additional land are required and there is not a substantial increase in the number of users. 10. Construction of bus transfer facilities (an open area consisting of passenger shelters, boarding areas, kiosks and related street improvements ) when located in a commercial area or other high activity center in which there is adequate street capacity for projected bus traffic. 11. Construction of rail storage and maintenance facilities in areas used predominantly for industrial or transportation purposes where such construction is not inconsistent with existing zoning and where there is no significant noise impact on the surrounding community. 12. Acquisition of land for hardship or protective purposes, advance land acquisition loans under section 3 (b) of the UMT Act. Hardship and protective buying will be permitted only for a particular parcel or a limited number of parcels. These types of land acquisition will not limit the evaluation of alternatives, including shifts in alignment for planned 3 ?i construction projects, which may be required in the NEPA process. No project development on such land may proceed until the NEPA process has been completed. D. Special Project Information Environmental Commitments: All standard procedures and measures will be implemented to avoid or minimize environmental impacts. Strict adherence to Best Management Practices (BMP's) will be included in the design and properly implemented during project construction. In accordance with the provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344), a permit will be required from the Corps of Engineers for the discharge of dredged or fill material into "Waters of the United States." An Army Corps of engineers Nationwide Permit # 23 or General Regional Permit No. 31 will likely be applicable to this project. Prior to issue of the Army Corps of Engineers Nationwide Permit # 23 a North Carolina Division of Environmental Management (DEM) Section 401 Water Quality General Certification must be obtained. The North Toe River is Hatchery Supported Designated Public Mountain Trout Water in addition to supporting some wild rainbow and brown trout. The following will be implemented during construction: • Construction will be accomplished so that wet concrete does not contact river water. This will lessen the chance of altering the river's water chemistry and causing a fish kill. • Where possible, heavy equipment will be operated from the bank rather than in the river channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the river. • Temporary or permanent herbaceous vegetation will be planted on all bare soil within 15 days of the completion of ground disturbing activities to provide long term erosion control. Estimated Costs: Construction $ 500,000 Right of Way $ 55,000 Total $ 555,000 Estimated Traffic: Current - 500 vehicles per day (VPD), Year 2020 - 900 VPD Functional Classification: Rural Local Route Division Office Comments: The Division 11 Engineer concurs with the recommendation of this document. Design Exceptions: A design exception is anticipated due to vertical alignment. 4 4 ? E.

Region Coordinator Habitat Conservation Program DATE: August 6, 1996 SUBJECT: Review of scoping sheets for Bridge #65 on SR 1117 over the North Toe River, Avery County, TIP #B-2916. This correspondence responds to a request by you for our review and comments on the scoping sheets for the subject project. The North Toe River is Hatchery Supported Designated Public Mountain Trout Water at the project site and also supports some wild rainbow and brown trout. We have the following recommendations regarding this project: 1) We prefer that the existing bridge be replaced with another spanning structure. We do not believe that a timing restriction would be necessary while installing a new spanning structure. 2) If a multi-cell reinforced concrete box culvert is the proposed replacement structure, then the structure should be designed so that all water flows through one cell (or two if necessary) during low flows. This will ensure that water depth through the structure is deep enough to allow fish passage. -In addition, no instream work should take place between November 1 - April 15 to protect the spawning stages of trout. 3) Construction must be accomplished so that wet concrete does not contact river water. This will lessen the chance of altering the river's water chemistry and causing a fish kill. 4) If possible, heavy equipment should be operated from the bank rather than in the river channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the river. 5) Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 days of ground disturbing activities to provide long-term erosion control.

Crow, Director On July 17, 1996, Debbie Bevin 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. 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. 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. Having provided this information, we look forward to receipt of either a Categorical Exclusion or Environmental Assessment which indicates how NCDOT addressed our comments. The above comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966 and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. 109 East Jones Street • Raleigh, North Carolina 27601-2807 Q33 Thank you for your cooperation and consideration.

The purpose of this is to inventory and describe the natural resources which occur within the proposed right-of-way boundaries and which are likely to be impacted by the proposed action. Assessments of the nature and severity of probable impacts to these natural resources are provided, along with recommendations for measures which will minimize resource impacts. This report identifies areas of particular environmental concern which may affect the selection of a preferred alignment or may necessitate changes in design criteria. Such environmental concerns should be addressed during the preliminary planning stages of the proposed project in order to maintain environmental quality in the most efficient and effective manner. The analyses contained in this document are relevant only in the context of the existing preliminary project boundaries and design. If design parameters and criteria change, additional field investigations may be necessary. 1.1 Project Description The proposed project crosses the North Toe River 4.0 km (2.5 mi) west of the town of Newland (Figure 1). The project calls for the replacement of Bridge No. 65 on SR 1117 over the North Toe River in Avery County. The existing structure is 7.8 m (25.5 ft) wide and 32.3 m (106.0 ft) long. The current right-of-way for this project is ditchline to ditchline and the proposed right-of-way is 24 m (80 ft). Two alternatives are being considered for the project. • Alternative 1: Replace the existing bridge with a 4 @ 3.1 m by 3.1 m (10.0 ft by 10.0 ft) reinforced concrete box culvert (RCBC) on existing location. Traffic will be detoured along secondary roads during construction. Project length is approximately 76 m (250 ft). • Altemative 2: Replace the existing bridge with a 4 @ 3.1 m by 3.1 m (10.0 ft by 10.0 ft) reinforced concrete box culvert (RCBC) on new location to the south of the existing bridge. Traffic would be maintained on the existing bridge during construction. Project length is approximately 252 m (825 ft). 1.2 Methodology Research was conducted prior to field investigations. Published resource information pertaining to the project area was gathered and reviewed. Resources utilized in this preliminary investigation of the project area include: • Geological Survey (USGS) quadrangle maps (Newland). • NCDOT aerial photographs of the project area (1:1200). )U N Y tt Cranberry -Z HUMP 1301 TAIN 19E \ 1 166 194 12 1167 1161 to 1177. 1315 4^? i 2 1205 •? 1190- ? 1160 C,. 1344 + 1 32 v 1162 •?;' 1353 134; r . $ . v Min polls 1180 Q 115 1157 r 1.159 rn ?i 1200 t 1185 -?• I 1346 (D 1 (v 137 1~156 1 15 1 1 1' . t; ?V•°Iby 1163 1 136 Q ?.. t. 2 BIG HAW `i 4 ?. 9 2 MOUNTAIN 1132 • 6 ELEV. 4.Fc'" t 1 17 l t 135 1207 y t 1 °5 1 t a t {: ( 'al l .-- , 1372 N. ??? :?

Water resource information was obtained from publications of the Department of Environment, Health and Natural Resources (DEHNR, 1993). Information concerning the occurrence of federal and state protected species in the study area was obtained from the FWS list of protected and candidate species (02 May 1997) and from the N. C. Natural Heritage Program (NCNHP) database of rare species and unique habitats. NCNHP files were reviewed for documented occurrences of state or federally listed species and locations of significant natural areas. General field surveys were conducted along the proposed alignment by NCDOT Environmental Biologists Matt Smith, Marc Recktenwald, and Dale Suiter on 9 April 1997. Water resources were identified and their physical characteristics were recorded. Plant communities and their associated wildlife were also identified and described. Terrestrial community classifications generally follow Schafale and Weakley (1990) where possible, and plant taxonomy follows Radford, el al. (1968). Animal taxonomy follows Martof, et al. (1980), Menhenick (1991), Potter, et al. (1980), and Webster, et al. (1985). Vegetative communities were mapped utilizing aerial photography of the project site. Predictions regarding wildlife community composition involved general qualitative habitat assessment based on existing vegetative communities. Wildlife identification involved using a variety of observation techniques: qualitative habitat assessment based on vegetative communities, active searching, identifying characteristic signs of wildlife (sounds, scat, tracks and burrows). Cursory surveys of aquatic organisms were conducted and tactile searches for benthic organisms were administered as well. Organisms captured during these searches were identified and then released. Jurisdictional wetlands, if present, were identified and evaluated based on criteria established in the "Corps of Engineers Wetland Delineation Manual" (Environment Laboratory, 1987) and "Guidance for Rating the Values of Wetlands in North Carolina" (Division of Environmental Management, 1995). Wetlands were classified based on the classification scheme of Cowardin, et al. (1979). 1.3 Terminology and Definitions For the purposes of this document, the following terms are used concerning the limits of natural resources investigations. "Project area" denotes the area bounded by the proposed right-of-way limits along the full length of the project alignment. "Project vicinity" is defined as an area extending 1.0 km (0.6 mi) on all sides of the project area, and "Project region" denotes an area equivalent in size to the area represented by a 7.5 minute USGS quadrangle map, i.e. [163.3 sq. km (61.8 sq. mi)]. 3 1.4 Qualifications of Principal Investigator Investigator Matt K. Smith, Environmental Biologist Education: BS Marine Biology, University of North Carolina at Wilmington, 12/94. Certification: N.C. Certified Wastewater Treatment Plant Operator. Experience: Laboratory Technician, Takeda Chemical Products. Lepidoptera researcher, USDA Forest Service. Expertise: Native Lepidoptera collection, field biological inventories, water quality testing. 2.0 Physical Resources Soil and water resources which occur in the project area are discussed below with respect to possible environmental concerns. Soil properties and site topography significantly influence the potential for soil erosion and compaction, along with other possible construction limitations or management concerns. Water resources within the project area present important management limitations due to the need to regulate water movement and the increased potential for water quality degradation. Excessive soil disturbance resulting from construction activities can potentially alter both the flow and quality of water resources, limiting downstream uses. In addition, soil characteristics and the availability of water directly influence the composition and distribution of flora and fauna in biotic communities, thus affecting the characteristics of these resources. 2.1 Regional Characteristics Avery County lies in -the Grandfather Mountain Window of the Mountain Physiographic Province of North Carolina (Figure 2). Topography in the vicinity of the study area is composed of steep slopes and wide floodplains along streams. Project elevations average 1080 in (3540 ft) above mean sea level. Soils of uplands in the project region have developed in place from material weathered from biotite and granitic gneiss. Soils of stream bottoms and floodplains are formed from unconsolidated clay, silt, sand, and rock fragments. 2.2 Soils Soils located in the project area are of the Wedowee-Louisburg-Pacolet Association. An inventory of the specific soil types which occur in the project area can be found in Table 1. A brief description of each soil type is also provided. r'-_?/ - ??

Surface layers and subsoil is loam. Bedrock in these areas is within a depth of 12 cm (40 in). This soil has moderate permeability and low shrink-swell potential. The seasonal high water table is below 3.8 m (6.0 f3). No mapped soils that are listed as hydric soils or soils that are known to contain inclusions of hydric soils are found in the study area 2.3 Water Resources This section contains information concerning surface water resources likely to be impacted by the proposed project. Water resource assessments include the physical characteristics, best usage standards, and water quality aspects of the water resources, along with their relationship to major regional drainage systems. Probable impacts to surface water resources are also discussed, as are means to minimize impacts. 2.3.1 Best Usage Classification Water resources within the study area are located in the Nolichucky River Watershed (Subbasin # 04-03-06) of the French Broad River Drainage Basin.. SR 1117 crosses one perennial stream the North Toe River (Figure 2). Construction of alternate 2 will necessitate the construction of a crossing of the North Toe River on new location. Streams have been assigned a best usage classification by the Division of Water Quality (DWQ), formerly Division of Environmental Management (DEM), which reflects water quality conditions and potential resource usage. The North Toe River [DEM Index No. 7-2-(0.5), 8/3/92] is classified as "WS-III Tr". WS-III (Water Supplies III) refers to those waters protected as water supplies which are generally in low to moderately developed watersheds; suitable for all Class C uses. Class C refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation and agriculture. Tr (Trout water) is a supplemental water classification including waters suitable for natural trout propagation and maintenance of stocked trout. No waters classified as High Quality Waters (HQW), Water Supplies (WS-I or WS-II) or Outstanding Resource Waters (ORW) occur within 1.6 km (1.0 mi) of the project study area 5 2.3.2 Physical Characteristics of Surface Waters The North Toe River at SR 1117 is approximately 15 m (50 ft) wide and ranges in depth from 0.3-0.6 m (1.0-2.0 ft). The substrate in the study area is composed of sand, silt, gravel, and cobble. Large boulders and exposed bedrock are interspersed throughout the stream and create calm pools and swift runs. Downstream of the existing bridge stream terraces have been constructed in the stream channel. Terraces alter the natural flow of the stream by increasing depth, stabilizing flow, and eliminating microhabitats. Most of the streams natural riparian canopy has been removed and is currently maintained as a lawn. Remnants of the riparian canopy were observed immediately downstream of SR 1117. 23.3 Water Quality This section describes the quality of the water resources within the project area Potential sediment loads and toxin concentrations of these waters from both point sources and nonpoint sources are evaluated. Water quality assessments are made based on published resource information and existing general watershed characteristics. These data provide insight into the value of water resources within the project area to meet human needs and to provide habitat for aquatic organisms. 2.3.3.1 General Watershed Characteristics A single registered point source discharger (Newland WWTP) is located upstream of the town of Ingalls (the nearest industrialized area). Much of the remaining land in this watershed is undeveloped and nearly half lies within the Pisgah National Forest. Overall, the water quality in this watershed is extremely good. Potential sources of nonpoint source pollution include Christmas tree farming and abandoned mining operations. This has resulted in sedimentation problems in the upper North Toe River (DEM, 1994). To a lesser degree discharge from septic tanks may be a factor. 2.3.3.2 Benthic Macroinvertebrate Ambient Nehvork The Benthic Macroinvertebrate Ambient Network (BMAN), managed by the DWQ, is part of an ongoing ambient water quality monitoring program which addresses long term trends in water quality. The program monitors ambient water quality by sampling at fixed sites for selected benthic macroinvertebrates organisms, which are sensitive to water quality conditions. Samples are evaluated on the number of taxa present of intolerant groups [Ephemeroptera, Plecoptera, Trichoptera (EPT)] and a taxa richness value (EPT S) is calculated. A biotic index value is also calculated for the sample that summarizes tolerance data for all species in each collection. The two rankings are given equal weight in final site classification. The biotic index and taxa richness values primarily reflect the effects of chemical pollution and are a poor measure of the effects of such physical pollutants as sediment. Data collected from BMAN 6 sampling sites on the North Toe River in the vicinity of the proposed project can be found in Table 2. Table 2. BMAN data for the North Toe River and project vicini N.

Sources of point source and nonpoint source pollution are rare in the project vicinity. During years with high flow lower EPT values were recorded. This is likely due to moderate amounts of sedimentation that cause scour during high flow events (1994). The consistently good classifications show that water quality in the watershed is stable. 2.3.3.3 Point Source Dischargers Point source dischargers located throughout North Carolina are permitted through the National Pollutant Discharge Elimination System (NPDES) program administered by the DEM. All dischargers are required to register for a permit. The DWQ NPDES report lists one permitted discharger into the North Toe River within 8 km (5 mi) of SR 1117. The Town of Newland WWTP (Permit # NC0021857) is located 0.1 km (0.2 mi) upstream of the proposed project. This plant is permitted to discharge up to 2.16 MGD. 2.4 Summary of Anticipated Impacts Impacts to water resources in the project area are likely to result from activities associated with project construction. Activities likely to result in impacts are clearing and grubbing on streambanks, riparian canopy removal, instream construction, fertilizers and pesticides used in revegetation, and pavement installation. The following impacts to surface water resources are likely to result from the above mentioned construction activities. • Increased sedimentation and siltation downstream of the crossing and increased erosion in the project area. • Changes in light incidence and water clarity due to increased sedimentation and vegetation removal. 7 • Alteration of water levels and flows due to interruptions and/or additions to surface and ground water flow from construction. • Changes in and destabilization of water temperature due to vegetation removal. • Increased nutrient loading during construction via runoff from exposed areas. • Increased concentrations of toxic compounds in highway runoff. Increased potential for release of toxic compounds such as fuel and oil from construction equipment and other vehicles. Alteration of stream discharge due to silt loading and changes in surface and groundwater drainage patterns. In order to minimize potential impacts to water resources in the project area, NCDOT's Best Management Practices for the Protection of Surface Waters will be strictly enforced during the construction phase of the project. Impacts can be further reduced by limiting instream activities and revegetating stream banks immediately following the completion of grading. 3.0 Biotic Resources Biotic resources include terrestrial and aquatic communities. This section describes the biotic communities encountered in the project area, as well as the relationships between fauna and flora within these communities. The composition and distribution of biotic communities throughout the project area are reflective of topography, soils, hydrology, and past and present land uses. Descriptions of the terrestrial systems are presented in the context of plant community classifications. These classifications follow Schafale and Weakley (1990) where possible. Representative animal species which are likely to occur in these habitats (based on published range distributions) are also cited. Scientific nomenclature and common names (when applicable) are provided for each animal and plant species described. Subsequent references to the same organism refer to the common name only. Fauna observed during the site visit are denoted in the text with an asterisk M. 3.1 Biotic Communities Biotic communities include terrestrial and aquatic elements. Much of the flora and fauna described from biotic communities utilize resources from different communities, making boundaries between contiguous communities difficult to define. Three distinct communities were identified within the project area: Disturbed, High Elevation Red Oak Forest; and the North Toe River. Two separate components of the North Toe River are described: the riparian and aquatic components. 8 3.1.1 Disturbed The disturbed community includes residential lawns, roadside shoulders, bridge approaches, and a small Christmas tree farm. Diversity in this community is low compared to surrounding communities since much of it is maintained in a early successional state through mowing and herbicide application. Several species of native and non native species were observed in this community that had been planted .as part of an ornamental landscape. Common cultivated shrubs and trees are weeping willow (Salix babylonica), blue spruce (Picea pungens), great laurel (Rhododendron maximum), forsythia (Forsythia sp.), and dwarf Alberta spruce (). A cultivated stand. of frasier fir(Abies fraseri) with maintained ground cover of fescue (Festuca sp.) is also present in the study area. Residential lawns and roadside shoulders are dominated by grasses and perennial herbs that are low growing and hardy. Common species observed in these habitats are: dandelion (Taraxacum offrcinale), yarrow (Achillea millefolium), Carolina geranium (Geranium carolinianum), buttercup (Ranunculus sp.), crabgrass (Digitaria sp.), fescue (Festuca sp.), wild lettuce (Lactuca canadensis), and glecoma (Glecoma hederacea). 3.1.2 High elevation Red Oak Forest This community includes all forested areas of the study area. Portions of this community located within the proposed right-of-way, have experienced some form of disturbance, allowing for colonization by atypical species. The canopy in this community is composed of mature eastern hemlock (Tsuga canadensis), red oak (Quercus rubra), scarlet oak (Q. Coccinea), and red maple (Acer ruby un). An understory that includes saplings of canopy species, great laurel, American beech (Fagus grandifolia), ironwood (Carpirms caroliniana), and buckeye (Aesculus octandra) is also present. Ground cover in this community contains a variety of herbs and fems including: birdfoot violet (Yola pedata), yellow violet (Viola rotundifolia), windflower (Anemone sp.), Christmas fern (Polystichum acrostichoides), possum grape (Ytis vulpina), blue cohosh (Caulophyllum thalictroides), puttyroot (Aplectrum hyemale), beech drops (Epiphagus grandifolia), and golden alexander (Taenidia integerrima). 3.1.4 Wildlife The disturbed community provides foraging opportunities for many species, both herbivores and carnivores. The majority of those species that forage in disturbed communities utilize forested communities as shelter. Species that are commonly observed in disturbed communities in the high mountains of North Carolina are eastern garter snake (Thamnophis sirtalis), eastern cottontail (Sylvilagus floridanus), eastern mole (Scalopus aquasicus), eastern chipmunk (Tamias striasus), woodchuck (Marniota monax), woodland vole (Microns pinetor un), gray fox (Yulpes vulpes), raccoon (Procyon losor), striped skunk (Mephitis mephitis), American robin* (Turdus migrasorius), turkey vulture (Catharses aura), and northern cardinal* (Cardinalis cardinalis). Forested communities offer a greater diversity of habitats than do disturbed communities and also provide habitat for interior species. Interior species are those species that require a 9 minimum area of a particular habitat type to survive. Fauna typical found in high elevation red oak forests and less frequently the disturbed community that borders it are American toad (Bufo americanus), gray treefrog (Hyla chrysoscelis), spring peeper (Hyla crucifer), box turtle (Terapene carolina), broadhead skink (Eumeces laticeps), five lined skink (E. fasciatus), worm snake (Carphophis. amoenus), timber rattlesnake (Crotalus horridus), northern short-tailed shrew (Blarina brevicauda), red squirrel (Tamiasciurus hudsonicus), deer mouse (Peromyscus maniculatus), white-tailed deer (Odocoleus virginianus), song sparrow (Melospiza melodia), white-eyed vireo* (Vireo griseus), and northern junco (Junco hyenralis). 3.1.3 North Toe River The community that is defined by the North Toe River is composed of riparian and aquatic habitats. These two types of habitats are separated here for convenience of description. Boundaries between aquatic and riparian habitats are frequently ill-defined and many common species will exploit both habitat types at some point in their life history. 3.1.3.1 Riparian Habitats The riparian community is found along the banks and the narrow floodplain of the North Toe River. Much of the canopy in this community has been removed, thus many atypical species were observed along the stream banks. The remnant canopy is dominated by yellow birch (Betula alleghaniensis). Other areas that appear to be mowed frequently contain bee-balm (Monarda didyma), bittercress (Cardamine sp.), tag alder (Alnus serrulata), yellow root (Xanthorhiza simplicissima), jewel weed (Impatiens carpensis), birdfoot violet, curly dock (Rumex crispus), winter cress (Barbarea vulgaris), chickweed (Stellaria sp.), soft rush (Juncos effiisus), wood rush (Luzula multiflora), bluets (Houstonia sp.), golden ragwort (Senecio aoreus), cutleaf toothwort (Denlaria diphylla), 'knot weed (Polygonum cuspidatum), and elderberry (Sambucus canadensis). Habitats found in riparian communities provide shelter for species that are primarily terrestrial, but feed on aquatic organisms. Seal salamander (Desmognathus monticola) and mountain dusky salamander (D. ochrophaeus) can be found under rocks and logs near streams. Belted kingfisher (Megaceryle alcyon) is commonly observed perched in overhanging branches and mallards (Anas platyrhynchos)* nest in grassy streambanks. Queen snake (Regina septemvittata) and northern watersnake (Nerodia sipedon) can be seen sunning on rocky streambanks. Streambanks are often riddled with mammal runs, usually formed by muskrat (Ondatra zibethicus). Other small mammals can be observed in this community include smoky shrew (Sorex fumeus), white-footed mouse (Peromyscus leucopus), and hispid cottonrat (Sigmodon hispidus). 10 3.1.3.2 Aquatic Habitats Species described in this section are limited to those that spend their entire lives in the aquatic environment. Those species that return to water to reproduce are included with the community that they occupy as adults. Many aquatic species serve as a food source for species found in the riparian community and to a lesser extent in upland communities. Habitats found in the North Toe River are composed of deep rocky runs and deeper pools. Habitat diversity in the study area is low as a result of the placement of several dams immediately downstream of the study area. Blackbelly salamander (D. quadra?naculatus) and shovelnose salamander (Leurognathus marmoratus) can be found under rocks in shallow riffles zones. Piscine species potentially found in the study area are: rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutla), central stoneroller (Campostoma anomalum), river chub (Nocomis micropogon), whitetail shiner (Notropis galacturus), Tennessee shiner (Notropis leuciodus), longnose dace (Rhinichthys cataractae), redbreast sunfish (Lepomis aurutus), smallmouth bass (Microplerus dolomieui), greenside darter (Etheostoma blennioides), and mottled sculpin (Cottus bairdi). 3.2 Summary of Anticipated Impacts Construction of the proposed project will have various impacts on the biotic resources described. Any construction related activities in or near these resources have the potential to impact biological functions. This section quantifies and qualifies potential impacts to the natural communities within the project area in terms of the area impacted and the organisms affected. Temporary and permanent impacts are considered here as well, along with recommendations to minimize or eliminate impacts. 3.2.1 Terrestrial Impacts Impacts to terrestrial communities will result from project construction due to the clearing and paving of portions of the project area, and thus the loss of community area. Table 2 summarizes potential losses to these communities, resulting from project construction. Calculated impacts to terrestrial communities reflect the relative abundance of each community present in the study area. Estimated impacts are derived based on the project lengths described in section 1. 1, and the entire proposed right-of-way width of 24 m (80 ft). However, project construction often does not require the entire right-of-way; therefore, actual impacts may be considerably less. Table 2. Estimated area impacts to terrestrial communities. Disturbed 0.08 (0.20) 0.37 (0.92) High Elevation Red Oak Forest 0.06 (0.14) 0.16 (0.39) Riparian 0.01 (0.032) 0.02 (0.040) Total Impacts 0.15 (0.37) 0.55 (1.4) 11 From a natural resources standpoint Alternative 1 is preferable because it will result in fewer impacts. As the construciton of this alternate will minimize impacts to natural communities. The projected loss of habitat resulting from construction of alternate 1 will have a minimal impact on populations of native fauna and flora. Although the impacted natural communities are valuable as wildlife habitat, only a small area of the undisturbed community will be impacted. Construction will primarily impact the disturbed community which is already highly altered from its natural state. Plants and animals found in this community are generally common throughout North Carolina and are well adapted to persisting in disturbed areas. Animals temporarily displaced by construction activities should repopulate areas of suitable habitat following project completion. Narrow zones along the edge of the forested community will be impacted by project construction. By reducing the overall areas of forested tracts, the amount of suitable habitat for interier species is reduced. Thus increasing opportunities for edge species. Interier species are those that require .... If forested tracts become too small in area interior species will not repopulate. 3.22 Aquatic Impacts Impacts to the aquatic community of the North Toe River will result from the replacement of Bridge No. 65. Impacts are likely to result from the physical disturbance of aquatic habitats (i.e. substrate, water quality, stream banks). Disturbance of aquatic habitats has a detrimental effect on aquatic community composition by reducing species diversity and the overall quality of aquatic habitats. Physical alterations to aquatic habitats can result in the following impacts to aquatic communities. • Inhibition of plant growth. • Clogging of feeding structures of filter-feeding organisms, gills of fish, and the burial of benthic organisms. • Algal blooms resulting from increased nutrient concentrations. • Mortality among sensitive organisms resulting from introduction of toxic substances and decreases in dissolved oxygen. • Destabilization of water temperature resulting from riparian canopy removal. • Loss of benthic macroinvertibrates through scouring resulting from an increased sediment load. Impacts to aquatic communities can be minimized by minimizing riparian canopy removal, limiting instrea n construction, revegetation immediately following the completion of grading activities, and strict adherence to BMP's. 4.0 Jurisdictional Topics This section provides inventories and impact analyses pertinent to two significant regulatory issues: Waters of the United States and rare and protected species. These issues retain particular significance because of federal and state mandates which regulate their 12 protection. This section deals specifically with the impact analyses required to satisfy regulatory authority prior to project construction. 4.1 Waters of the United States Surface waters and wetlands fall under the broad category of "Waters of the United States," as defined in Section 33 of the Code of Federal Register (CRF) Part 328.3. Any action that proposes to dredge or place fill material into surface waters or wetlands falls. under the jurisdiction of the U.S. Army Corps of Engineers (COE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Surface waters include all standing or flowing waters which have commercial or recreational value to the public. Wetlands are identified based on the presence of hydric soils, hydrophytic vegetation, and saturated or flooded conditions during all or part of the growing season. 4.1.1 Characteristics of Wetlands and Surface Waters Criteria to delineate jurisdictional wetlands include evidence of hydric soils, hydrophytic vegetation and hydrology. No jurisdictional wetlands were identified in the study area. Impacts to jurisdictional surface waters are calculated based on the linear feet of the stream that is located within the proposed right-of-way. Physical aspects of surface waters are described in section 2.3.1. The North Toe River is the only jurisdictional surface water located in the study area. An area of approximately 1220 m2 (4000 f12) and a length of 24 linear m (80 linear f3) of the North Toe River will be impacted by the proposed project. In order to minimize impacts to jurisdictional surface waters Alternate 1 is the preferred alternative. 411.3 Permits Impacts to jurisdictional surface waters are anticipated from the proposed project. As a result, construction activities will require permits and certifications from various regulatory agencies in charge of protecting the water quality of public water resources A Nationwide Permit 33 CFR 330.5(a) (23) is likely to be applicable for all impacts to Waters of the United States resulting from the proposed project. This permit authorizes activities undertaken, assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency or department where that agency or department has determined the pursuant to the council on environmental quality regulation for implementing the procedural provisions of the National Environmental Policy Act: • (1) 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; 13 • (2) that the office of the Chief of Engineers has been furnished notice of the agency' or department's application for the categorical exclusion and concurs with that determination. This project will also require a 401 Water Quality Certification from the DWQ prior to the issuance of the Nationwide Permit. Section 401 of the Clean Water Act requires that the state issue or deny water certification for any federally permitted or licensed activity that may result in a discharge to Waters of the United States. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulation. The issuance of a 401 permit from the DWQ is a prerequisite to issuance of a Section 404 permit. Since, the proposed project crosses waters designated as Trout Waters, the authorization of a Section 404 Nationwide permit by the COE is conditioned upon concurrence of the WRC. 4.L4 Avoidance, Minimization, Mitigation The COE has adopted through the Council on Environmental Quality (CEQ) a wetland mitigation policy which embraces the concept of "no net loss of wetlands" and sequencing. The purpose of this policy is to restore and maintain the chemical, biological and physical integrity of Waters of he United States, specifically wetlands. Mitigation of wetland impacts has been defined by the CEQ to include: avoiding impacts (to wetlands), minimizing impacts, rectifying impacts, reducing impacts over time and compensating for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization and compensatory mitigation) must be considered sequentially. Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts to Waters of the United States. According to a 1990 Memorandum of Agreement (MOA) between the Environmental Protection Agency (EPA) and the COE, in determining "appropriate and practicable" measures to offset unavoidable impacts, such measures should be appropriate to the scope and degree of those impacts and practicable in terms of cost, existing technology and logistics in light of overall project purposes. Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts to Waters of the United States. Implementation of these steps will be required through project modifications and permit conditions. Minimization typically focuses on decreasing the footprint of the proposed project through the reduction to median widths, rirght-of- way widths, fill slopes and/or road shoulder widths. Compensatory mitigation in not normally considered until anticipated impacts to Waters of the United States have been avoided and minimized to the maximum extent possible. It is recognized that "no net loss of wetlands" functions and values may not be achieved in each and every permit action. Appropriate and practicable compensatory mitigation is required for unavoidable adverse impacts which remain after all appropriate and practicable minimization has been required. Compensatory actions often include restoration, creation and enhancement of Waters of the United States, specifically wetlands. Such actions should be undertaken in areas adjacent to or contiguous to the discharge site. 14 Compensatory mitigation is required for those projects authorized under Nationwide Permits that result in the fill or alteration of • More than 0.45 ha (1.0 ac) of wetlands will require compensatory mitigation; • And/or more than 45.7 in (150.0 linear ft) of streams will require compensatory mitigation. Written approval of the final mitigation plan is required from the DWQ prior to the issuance of a 401 Certification. Final permit/mitigation decisions rest with the COE. 4.2 Rare and Protected Species Some populations of fauna and flora have been in, or are in, the process of decline either due to natural forces or their inability to coexist with human development. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action, likely to adversely affect a species classified as federally-protected, be subject to review by the United States Fish and Wildlife Service (FWS). Other species may receive additional protection under separate state laws. 4.2.1 FederallkNotected Species Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under the provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of 02 May 1997, the FWS lists ten federally protected species for Avery County. A brief description of the characteristics and habitat requirements for these species along with a conclusion regarding potential project impacts follows Table 3. Table 3. Federally Protected bog turtle Virginia big-eared bat peregrine falcon Carolina northern flying squirrel ies for A Clemmys muhlenbergii Plecolus lownsendii virginiarats Falco peregrimts Glaucomys sabrinus coloratus Proposed T(S/A) Endangered Endangered Endangered spruce-fir moss spider Microhezura montivaga Endangered spreading avens Getan radialum Endangered Roan Mountain bluet Houstonia niontana Endangered Heller's blazing star Liatris helleri Threatened Blue Ridge goldenrod Solidago spithamaea Threatened rock enome lichen Gvmnodernta lineare Endangered Note: • "Endangered" denotes a species in danger of extinction throughout all or a significant portion of its range. 15 • "Threatened" denotes a species likely to become endangered within the foreseeable future throughout all or a significant portion of its range. • "Proposed T (S/A)" denotes a species that is proposed for official listing as threatened due to similarity of appearance to other rare species. Clemmys muhlenburgii (bog turtle) Proposed T (S/A) Family: Emydidae Federally Listed: 01 May 1997 The bog turtle is North Carolina's smallest turtle, measuring 7 to 10 cm (3 to 4 in) in length. It has a dark brown carapace and black plastron. The orange or yellow blotch on each side of the head and neck is a readily identifiable characteristic. It inhabits damp grassy fields, bogs and marshes in the mountains and western piedmont. The bog turtle is shy and secretive, and will burrow rapidly in mud or debris when disturbed. The bog turtle forages on insects, worms, snails, amphibians and seeds. In June or July three to five eggs are laid in a shallow nest in moss or loose soil. The eggs hatch in about fifty five days. (Bernard S. Martof, et. al., 1980). The bog turtle is listed as Proposed Threatened due to similarity of Appearance with other rare species that are listed for protection. Species listed as T (S/A) are not biologically endangered or threatened and are not subject to Section 7 consultation. Corynorhinus (=Plecotus) townsendii virginianus (Virginia big-eared bat) Endangered Family: Vespertilionidae Date Listed: 30 October 1979 Corynorhinus lowmsendii is widespread throughout the western United States and the eastern subspecies only exists in a few fragmented populations. These populations are found in caves near the Potomac River in eastern West Virginia, Tazwell County, Virginia, and Lee County, Kentucky. It was not observed in North Carolina until the early'80's, when small populations were discovered in Avery and Watauga counties. The Virginia big-eared bat is most easily identified by large ears (more than 2.5 cm) and large glandular masses on its muzzle. The ears are held erect when the bat is awake and are curled around the head when it is hibemating or at its summer roost. This bat has an overall length of 92- 112 mm and weighs from 9-12 grams. The Virginia big-eared bat has long, soft fur that is brown in color and darker on the dorsal side. The hair on the feet does not extend beyond the toes. Virginia big-eared bats are permanent residents of caves in oak-hickory forests and mines. Hibernating colonies are typically located in deep cave passage ways that have stable temperatures and air movement. Temperature in these hibemacula average (6-12 C), lower than that tolerated by most other bats. Maternity colonies are formed in warm caves in the spring. 16 This species is nocturnal and feeds on moths, beetles, and other insects. Bats mate in the fall and winter and a single young is bom in June. The young grow rapidly and reach adult within a single month, with females becoming reproductively active by the following fall. Biological Conclusion: No Effect Suitable habitat in the form of caves or abandoned mine shafts is not found in the study area. The potential existings for this species to utilize the riparian habitats in the study area for foraging, hoever, constuction of the proposed project will not limit foraging opportunities for this species. No records for this species were found in the NHP database of rare species and unique habitats. Therefore, the construction of the proposed project will not affect the Virginia big- eared bat. Falco peregrinus (Peregrine falcon) Endangered Family: Falconidae Date Listed: 20 March 1984 The peregrine falcon has a dark plumage along its back and its underside is lighter, barred and spotted. It is most easily recognized by a dark crown and a dark wedge that extends below the eye forming a distinct helmet. Immature peregrine falcons have dark-brownish backs and heavily streaked underparts. The peregrine falcon has pointed wings in flight, a common characteristic among falcons. The peregrine falcon is roughly the size of a crow, between 41-51 cm long and 91-112 cm wide. In this species the female is roughly 25% larger than the male. The American peregrine falcon is found throughout the United States in areas with high cliffs and open land for foraging. Nesting for the falcons is generally on high cliff ledges, but they may also nest in broken off tree tops in the eastern deciduous forest and on skyscrapers and bridges in urban areas. Nesting occurs from mid-March to May. Prey for the peregrine falcon consists of small mammals and birds, including mammals as large as a woodchuck, birds as large as a duck, and insects. The preferred prey is medium sized birds such as pigeons. Peregrine falcons are at the top of their food chain and are therefore extremely sensitive to chemical toxins such as DDT. Biological Conclusion: No Effect The landscape surrounding the proposed project does not include high cliffs, nor do the forested communities present contain large dead trees. Since, these features are not present in the study area,suitable nesting sites for the peregrine falcon are not present in the study area. The roadsides and open streambanks could potentially be utilized by the falcon for foraging; however, these communities are anticipated to be reestablished prior to project completion. The NHP database of rare species and unique habitats contains no recorded occurrences of this species in the project vicinity. Therefore, construction of the proposed project will not affect the peregrine falcon. Glaucomys sabrinus coloralrrs (northern flying squirrel) Endangered Family: Sciurdiae 17 Date Listed: 1 July 1985 Populations of the northern flying squirrel are stable throughout most of its range. After the Pleistocene Epoch glaciations this species underwent speciation in the southern part of its range resulting in the coloratus and fuscus subspecies. Populations of coloralus are considered to be isolated relicts and have a patchy distribution in the southern Appalachian Mountains. Known populations occur at Grandfather Mountain, Mt. Mitchell, the Great Balsam Mountains, the Plott Balsam Mountains, the Great Smokey Mountains (Jackson and Swain Counties), the Unicoi Mountains, and the Long Hope Valley area. The northern flying squirrel is a small gliding rodent, measuring from 26-31 cm in total length and weighing from 95-140 gm. This squirrel has a large well furred flap of skin along either side of its body, this flap of skin is connected at the wrist in the front and at the ankle in the rear. The skin flaps and broad flattened tail allow the northern flying squirrel to glide from tree to tree. It is a solely nocturnal animal with large dark eyes. Juvenile squirrels have a uniform dark gray back and an off-white underside. Adult squirrels are characteristically gray with a brownish, tan, or reddish wash on the back, and a grayish-white to buffy white underside. This squirrel is found in the vegetation transition zone between hardwood and coniferous forests, above 1517 meters (5000 ft). Foraging occurs in both communities with nesting only occuring in the Hardwood Community type. Northern flying squirrels feed on lichens, fungi, seeds, buds, fruit, staminate cones, insects, and animal flesh. Winter shelters are found in tree cavities, woodpecker holes. Leaf nests are most commonly occupied in the summer. The inside of their nests is lined with lichens, moss, or finely chewed bark. A West Virginia study has preliminary results that show the use of burrows by northern flying squirrels. Biological conclusion: No Effect Elevations in the study area [1080 in (3540 ft] are inadequate to support the transitional zone between hardwood and high elevation coniferous forests that this species requires. The NHP database of rare species and unique habitats contains no records of this species for the project vicinity. Therefore, no impacts to this species will result from project construction. Microhexura montivaga (spruce-fir moss spider) Endangered Family: Dipluridae Date Listed: 27 January 1994 The spruce-fir moss spider is the northern most representative of the family Dipluridae (Tarantulas). It is also one of the smallest spiders in this primitive group, 3.0-5.6 mm (0.25-0.45 in). Coloration ranges from light brown to dark reddish brown, with no abdominal markings. Field identification characteristics include a pair of very long posterior spinnerets and the presence of a second pair of book lungs, which appear as light patches postier to the genital furrow. Males of the species mature during September and October, and females are known to lay eggs in June. The egg sac usually contains between seven to nine eggs. The life span of these spiders is unknown although it has been estimated that maturity may take four years. 18 . The spruce-fir moss spider occurs in well-drained moss and liverwort mats growing on rocks or boulders. These mats are found in well-shaded areas of mature, high elevation (> 1524 m/5000 $) spruce-fir forests. This species is currently known from only four populations one in Tennessee, one in Avery/Caldwell County, and two in Swain County. Individuals are very sensitive to desiccation and require constant high humidity. Constant high humidity helps to maintain the necessary level of moisture in the moss mats, neither parched nor saturated. The spider constructs its tube-shaped webs in the interface between the moss mat and the rock surface. Some webs have been found to extend into the interior of the moss mat. No prey has been found in the webs, but the probable prey for the spruce-fir moss spider is the abundant springtails found in moss mats. The continued existence of the spruce-fir moss spider is related directly to habitat loss/alteration of the spruce-fir forest from air pollution and exotic insect pests, particularly the balsam wooly adelgid. The loss and reduction of the forest canopy results in localized changes in microclimate, including increased temperatures, increased light and decreased moisture on the forest floor. These alterations of the microclimate lead to desiccation of the moss mats on which the spider and, possibly its prey base, depend for survival. Biological conclusion: No Effect Elevations in the study area [1080 m (3540 $)] are to low to support suitable habitat for the spruce-fir moss spider. The NIP database of rare species and unique habitats contains no records of this species in the project vicinity. Therefore, the construction of the proposed project will not impact the spruce-fir moss spider. Geum radialum (spreading avens) Endangered Family: Rosaceae Federally Listed: 5 April 1990 Flowers Present: June - early July This species is found only in the North Carolina and Tennessee sections of the Southern Appalachian Mountains. Known populations in Burke County have been extirpated and populations in any other counties have shown a serious decline. Stems of this perennial herb grow from horizontal rhizomes and obtain a height of 2-5 decimeters. The stems are topped with an indefinite cyme of bright yellow radially symmetrical flowers. Basal leaves are odd-pinnately compound, terminal leaflets are kidney shaped and much larger than the lateral leaflets, which are reduced or absent. Leaflets have lobed or uneven margins and are serrate, with long petioles. Stem leaves are smaller than the basal, rounded to obovate, with irregularly cut margins. Fruits are hemispheric aggregates of hairy achenes that are 7-9 mm in diameter. Spreading avens occurs on scarps, bluffs, cliffs and escarpments on mountains, hills, and ridges. Known populations of this plant have been found to occur at elevations of 1535-1541 meters (5060-5080 feet), 1723-1747 meters (5680-5760 feet) and 1759 meters (5800 feet). Other habitat requirements for this species include full sunlight and shallow acidic soils. The 19 spreading avers is found in soils composed of sand, pebbles, humus, sandy loam, clay loam, and humus. Most populations are pioneers on rocky outcrops. Biological Conclusion: No Effect No suitable habitat in the form of high mountain rocky outcrops occur in the study area Also, project elevations [1080 m (3540 ft)] are to low to support the suitable habitat for this species. The NHP database of rare species and unique habitats contains no recorded occurrences of this species in the project vicinity. Hedyotis purpurea var. montana (Roan Mountain bluet) Endangered Family: Rubiaceae Federally Listed: 5 April 1990 Flowers Present: June - July (best time is mid June) Hedyotis purpurea var. montana is known historically from seven populations in the southern Appalachian mountains of North Carolina and Tennessee. These populations of Hedyotis purpurea- var. montana are threatened by land use as well as natural succession. This perennial species is shallow rooted and grows in low tufts 1 to 2 dm tall. The median cauline leaves are 1 to 3 centimeters long. It has several bright purple flowers arranged in a terminal cyme. The seed capsule quickly follows the flowers which form in July and early August. This plant can be found on high elevation cliffs, outcrops, steep slopes, and in the gravelly talus associated with cliffs. It grows best in areas where it is exposed to full sunlight and in shallow acidic soils composed of various igneous, metamorphic, and metasedimentary rocks. Biological Conclusion: No Effect Elevations in the study area [1080 m (3540 ft)] are too low to support suitable habitat for this species and no rocky cliffs occur in the study area The NHP database of rare species and unique habitats contains no records of this species in the project vicinity. Therefore, the construction of the proposed project will not impact the Roan Mountain bluet. Liatris helleri (Heller's blazing star) Threatened Plant Family: Asteraceae Federally Listed: 19 November 1987 Flowers Present: late June - August This plant is endemic to high elevation ledges of rock outcrops of the northern Blue Ridge Mountains in North Carolina. Of nine historic populations only seven remain in existence. Heller's blazing star is a short stocky plant that has one or more erect stems that arise from a tuft of narrow, pale green basal leaves. Leaves are accuminate and diminish in size and breadth upward on the stem. Stems are 4 dm tall and are topped with a raceme of small (7-20 cm) lavender flowers. Fruits are present from September to November. 20 This plant is a high altitude early pioneer species and can be found growing on high elevation ledges of rock outcrops in grassy areas where it is exposed to full sunlight. It prefers shallow acid soils associated with granite rocks. Biological Conclusion: No Effect Elevations in the study area [1080 in (3540 f3)] are too low to support suitable habitat for this species and no rocky outcrops are found in the study area. The NHP database of rare species and unique habitats contains no records of this species in the project vicinity. Therefore, the construction of the proposed project will not impact Heller's blazing star. Solidago spithamaea (Blue-Ridge goldenrod) Threatened Plant Family: Asteraceae Federally Listed: 28 March 1985 Flowers Present: mid July, - August The Blue-Ridge goldenrod is found only on high mountain peaks in North Carolina and Tennessee. This perennial herb has an erect 10 cm to 20 cm stem that grows from a short stout rhizome. The stem is terete and longitudinally striate, and greenish-brown proximally. It becomes more strongly ribbed and reddish distally, and is usually covered with whitish hairs. The stem is generally unbranched below the flower. The oblanceolate and spatulate leaves are acute with the offshoot and basal stem leaves being the largest and longest. The broad portions of the leaves are ascending-serrate and the bases are long-attenuate. Stem leaves are reduced and more sessile as they approach the top of the stem. The yellow flowers are bome in heads arranged in a corymbiform inflorescence. The Blue Ridge goldenrod inhabits rock outcrops, ledges, cliffs, and balds at elevations above 1400 meters. It grows in humus or clay loams on igneous and metasedimentary rock. Sites are usually exposed to full sun and have shallow acidic (pH 4) soils. Ideal sites are intermittently saturated but excessively to moderately poorly drained. Biological Conclusion: No Effect Elevations in the study area [1080 m (3540 f3)] are to low to support suitable habitat for this species and no habitats such as, balds, cliffs, ledges, or rocky outcrops are found in the study area. The NHP database of rare species and unique habitats contains no records of this species in the project vicinity. Therefore, the construction of the proposed project will not impact the Blue Ridge goldenrod. Gymnoderma lineare (Rock gnome lichen) Endangered Family: Cladoniaceae Federally Listed: 28 December 1994 Y 21 The rock gnome lichen is a squamulose lichen in the reindeer moss family. This lichen is a narrow endemic, restricted to areas of high humidity. These high humidity environments occur on high elevation (> 1220 m/ 4000 f3) mountaintops and cliff faces which are frequently bathed in fog or lower elevation (< 762 m/ 2500 f3) deep gorges in the Southern Appalachians. The rock gnome lichen primarily occurs on vertical rock faces where seepage water from forest soils above flows at (and only at) very wet times. The rock gnome lichen is almost always found growing with the moss Adreaea in these vertical intermittent seeps. The high elevation habitat occurs in the counties of Ashe, Avery, Buncombe, Graham, Haywood, Jackson, Mitchell, Rutherford, Swain, Transylvania, and Yancey. The lower elevation habitat of the rock gnome lichen can be found in the counties of Jackson, Rutherford and Transylvania. The terminal portions of the rock gnome lichen resemble strap-like lobes, having a blue- gray color on the upper surface and generally a shiny-white color on the lower surface. The color of the fungi near the base is black. The squamules are nearly parallel to the rock surface and are generally 1 to 2 centimeters in length. The fruiting bodies are born singly or in clusters, black in color, and are found at the tips of the squamules. The fruiting season of the rock gnome lichen occurs from July through September. The primary means of propagation appears to be asexual, with colonies spreading clonally. The major threat of extinction to the rock gnome lichen relates directly to habitat alteration/loss of high elevation coniferous forests. The thinning and death of these forest occurs from exotic insect pests, trampling of hikers and associated soil erosion and compaction from hikers. These coniferous forests usually lie adjacent to the habitat occupied by the rock gnome lichen. Drastic changes in microclimate (including increased temperatures and decreased moisture) result from the impacts to these forests. These alterations of the microclimate lead to the desiccation of the rock gnome lichen. Biological Conclusion: No Effect Elevations in the study area [1080 m (3540 ft)] are to low to support suitable habitat for this species and no habitats such as, balds or cliffs are found in the study area The NHP database of rare species and unique habitats contains no records of this species in the project vicinity. Therefore, the construction of the proposed project will not impact the rock gnome lichen. 4.2.2 Federal Species of Concern and State Listed Species There are twenty-three federal species of concern listed by the FWS for Avery County (Table 4). Federal species of concern are not afforded federal protection 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 or Endangered. However, the status of these species is subject to change, and so should be included for consideration. Federal Species of Concern (FSC) are defined as a species which is under consideration for listing for which there is insufficient information to support listing. In addition, organisms which are listed as Endangered (E), Threatened (T), or Special Concern (SC) by the North Carolina Natural Heritage Program 22 list of Rare Plant and Animal Species are afforded state protection under the NC State Endangered Species Act and the NC Plant Protection and Conservation Act of 1979. Table 4 lists federal species of concern, the state status of these species (if afforded state protection), and the potential for suitable habitat in the project area for each species. This species list is provided for information purposes as the protection status of these species may be upgraded in the future. 23 Table 4.

A review of the NBP data base of rare species and unique habitats shows an occurrence of Manhart's sedge in the study area Fraser fir was identified in the study area. Individuals observed are part of a stand that is being cultivated for Christmas trees. Fraser firs grown under these environmental conditions do not provide suitable habitat for the lichens Bazzania nuducaulis and Sphenolobopsis pearsoni. Surveys for FSC species were not conducted during the site visit. 24 5.0 REFERENCES American Ornithologists' Union. 1983. Check-List of North American Birds (6th ed.).
