GANNETT FLEMING AVOIDANCE, MIMIZATION, AND MITIGATION The re -pavement and drainage maintenance project would be located within the existing roadway and culvert limits of the BRP. No upgrades to roadway or upgrade extension to culverts are included in this project. The project repairs and maintains existing roadway and culverts resulting in an improvement for water quality to JD waters within the project study area (PSA). The project construction will be conducted in compliance with regional special conditions of Sec 401 and Sec 404 permits including construction staging on high ground, no construction equipment will be allowed in JD waters, appropriate erosion control devices will be constructed and maintained, culvert repair and maintenance will be constructed in "dry" with appropriate dewatering devices being constructed and maintained during construction, safety fencing will be used to delineate environmentally sensitive areas, etc. Onsite traffic control plan detours will be maintained during construction. Project does not result in any permanent loss of JD waters. All impacts are temporary JD impacts to both stream channels and wetlands. The net result would be an enhancement to water quality for JD waters within the project study area. No Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State are proposed for this project. FEDERALLY PROTECTED SPECIES Federal Highway Administration (FHWA), Eastern Federal Lands Highway Division NEPA Categorical Exclusion (CE) Form, Project No. BLR12B13-2H17, dated 8/24/202 1 included formal consultations with the Fish and Wildlife Service (FWS) that resulted in FHWA commitments to conservation measures to mitigate potential impacts associated with this project to Sec. 7 Threaten and Endangered species. Copy of the CE document and attachments are included in this application. INDIRECT CUMULATIVE IMPACT ANALYSIS The project is limited to the existing BRP without any upgrades and maintains current public use. The project does not include design or upgrades that would attract any new or additional development to area then what already exists. 14 GANNETT FLEMING CULTURAL RESOURCES NPS is the lead federal agency for Section 106 compliance. On July 13, 2021, NPS sent a consultation letter to the North Carolina State Historic Preservation Office (SHPO) containing the following assessment: The area of potential effects (APE) for this project includes the area that would be directly impacted by road maintenance (Sections 2A,2B, 2C, 2D, 2E, 2F, 2G, and 2H), as well as the area from which the maintenance activities would be visible and audible. Historic properties within the APE include the National Register of Historic Places (NRHP) eligible Blue Ridge Parkway Historic District (BN0905), and its contributing features of bridges, culverts, and landscaping, that are located within the Sections listed above. Several sections of the parkway and its contributing features of bridges, culverts, and landscaping will all be included as elements of this proposed project. The park has been working closely with the NCSHPO office, and through that consultation notes that the proposed work will not rise to the level of causing an adverse effect to the parkway. An NPS archeologist evaluated the project APE and does not anticipate any effects to unidentified cultural resources. Blue Ridge Parkway and NPS Southeast Regional Office subject matter experts have reviewed this project and determined it would have no adverse effect on the Blue Ridge Parkway Historic District. The SHPO concurred with the NPS determination in a letter dated August 20, 2021 (SHPO file ER-21-1921). FEMA COMPLIANCE None of the 14 PSA sites occur in FEMA-designated 100-year floodplain.

Project Description The project involves rehabilitation of sections 2B, 2C, 2D, 2E, 2F, 2G, and 2H of the Parkway. The following activities are proposed: • Heavy 3R (resurfacing, restoration, and rehabilitation). • Light 3R (edge erosion rehabilitation, pavement marking, crack sealing, light pavement patching). • Signage and pavement markings improvements for sight and distance aimed at enhancing safety (MUTCD standard). • Shoulder stabilization with aggregate topsoil and turf establishment or geogrid pavers. • Stone curb removal and resetting. • Asphalt sidewalk reconstruction at overlook parking areas. • Guardrail and stone guardwall repair and reconstruction. • Drainage improvements including cleaning, reconditioning, and repairing more than 300 culverts, headwalls, inlets, and outfalls. Ditch reconditioning, outlet protection and other improvements will also occur. • Minor repairs of 26 Bridges: cleaning and repointing stone masonry; cleaning and resealing deck joint and vertical joints; installing object markers and clearance signs; cleaning and sealing concrete decks; minor concrete repairs; mill and overlay; waterproofing membranes; structural concrete crack injection; removal of graffiti; repair broken utilities; clean and paint structural steel; bridge rail repairs; and miscellaneous grading and erosion repairs.

Deck replacement will be in -kind. The stone masonry guardwalls will be reconstructed to match the existing. Guardrail replacement will also occur. • Repair grade failures at Milepost 234, 235, and 263 with deep patches, Mechanically Stabilized Earth (MSE) walls, or other suitable methods. These activities will mostly be confined to the existing roadway and shoulder to rehabilitate the Parkway essentially in -kind. Limited ground disturbance, wetland impacts, stream impacts, and vegetation removal will occur, particularly related to drainage and slope repairs. FHWA and NPS will implement strict erosion control, best management practices, and minimize disturbances to natural and historic resources. Environmental Commitments and Mitigation Measures The following conservation measures are proposed to avoid and minimize potential effects to the Carolina Northern Flying Squirrel: • Conservation measures will be implemented in the Grandfather Mountain Corridor, MP 300-305 • Night work will not be permitted to avoid interference with nocturnal activities • All trees proposed for cutting or trimming will be marked by the construction contractor in the field and inspected by qualified contractor biologists, in coordination with FHWA/NPS prior to removal. The biologists will make the following determinations: o Biologists will inspect the trees to determine if they may contain CNFS nests. If suitable den trees must be cut, inspect accessible cavities visually and with peeper scope. Look for evidence of use such as finely shredded birch bark. Any trees containing confirmed nests will not be removed. o Biologists will direct contractor to avoid trees with cavities (e.g., old gnarly trees, snags, trees with woodpecker holes or rotted knotholes) and dreys (nests). In addition to yellow birch, den trees can be in other species including American beech, maple, buckeye, and spruce. Dreys are most often in conifers. o Given its importance as a den tree and source of nest material, avoid cutting yellow birch greater than 8 inches in diameter at breast height when possible, especially in mixed stands where yellow birch is limited. o Spruce and hemlock trees will not be removed unless they are posing a threat to the stability of the roadway or associated drainage features. • Contractor staff will be informed of the potential presence of CNFS. If flying squirrels of any type are observed by the contractor, they shall halt all work in the area and inform NPS/FHWA and USFWS immediately for further guidance. Page 2 of 10 EFLHD NEPA Categorical Exclusion Form EFL-TM-ENV-03(04) BLRI 2B 13-2H 17 Ob Eastern Federal Lands Highway Division U.S.Department g y of Transportation NEPA Categorical Exclusion Form Federal Highway Administration • Conduct tree removal work outside of the March 15 — August 30 time period when squirrels could have pups. • Avoid creating large canopy gaps along the road, which will limit squirrel movement. This is especially important in areas without many large trees. When creating gaps >40 feet wide, leave a tree for a launch point. The following conservation measures will be implemented to avoid and minimize impacts to bats: • Conservation measures will be implemented throughout the entire project corridor • No tree removal will occur between March 15 - November 15 • If bridge, culvert, or guardwall (structure) work needs to occur between March 15 and November 15 when bats could be present on the landscape, a qualified wildlife biologist with expertise in bats contracted by FHWA/NPS will check structures for evidence of bats. • The inspections shall occur as close to the beginning of work as possible but always within two weeks of construction activities beginning. • A bridge/structure assessment form approved by NPS in consultation with FWS will be used to document the survey. A copy of the most recent draft assessment form is included as Appendix G., When the form is finalized by NPS and approved by FWS, a copy of the most recent form will be provided to the contractor by NPS prior to the survey. • All bridges should be checked. • All culverts over 2-feet in diameter, regardless of material, should be checked. If culverts are big enough to walk through, someone should walk through to check for bats. • Guardwalls or retaining walls with cracks and crevices large enough to provide habitat for bats should be checked. • Checks should follow the Indiana State University Manual for Determining Bat Presence (see Appendix H). The manual will be provided to the contractor. • If evidence of bats is seen: • Contact the FWS immediately to discuss appropriate avoidance measures. No construction work shall begin at the structure location until discussions with FWS have concluded. • If evidence of bats is not found during the inspection of a structure, but evidence or bat sightings are unexpectedly made during construction, the contractor shall halt work. NPS/FHWA shall notify FWS immediately. Work will not resume at the structure until FWS/NPS/FHWA agree how to proceed. • The preferred avoidance measure is waiting for bats to leave for the season and conduct work between Nov 16 and March 14. If this cannot occur, FHWA and NPS will reinitiate consultation with the USFWS to assess impacts of the proposed activity and determine Page 3 of 10 EFLHD NEPA Categorical Exclusion Form EFL-TM-ENV-03(04) BLRI 2B 13-2H 17 Ob Eastern Federal Lands Highway Division U.S.Department g y of Transportation NEPA Categorical Exclusion Form Federal Highway Administration additional conservation measures. A more detailed survey and implementation plan may be required. This could include potential night work after bats leave for the evening, excluding bats, hand removal of bats, or other techniques as appropriate. • Regardless of when work is done, if bats are found, ensure habitat remains after bridge is repaired so bats can return the following season. • Reporting to FWS - forms documenting pre -construction checks should be sent to the FHWA/NPS by the contractor monthly or within one business day of encountering evidence of bats. NPS will provide a compilation of the reports to USFWS every 90 days, or whenever bats are documented, whichever is sooner. The following conservation measures will be implemented to avoid and minimize impacts to Swamp Pink: • Best management practices will be used to prevent indirect impacts by sedimentation. This will include the use of fiber roll or filter berm. An erosion and sediment control plan will be prepared and submitted to the North Carolina Department of Environmental Quality for review and approval • The contractor, NPS, and FHWA staff will not stage materials, equipment, or vehicles along the roadway shoulders between Milepost 248.0-249.0. • NPS staff will monitor hydroseeding and turf establishment activities within 100 meters of the known population to ensure that fescue or other seeds are not applied outside of the roadway shoulders. The following conservation measures will be implemented to avoid and minimize impacts to Rock Gnome Lichen: • The design will be carefully specified to avoid direct impacts. • Contactors and equipment will not enter the stream channel beneath Stack Rock Creek Bridge (Milepost 304) and construction debris will be contained/secured on the bridge deck until removal. Debris will be removed at the end of each workday. • The contractor, NPS, and FHWA staff will not stage materials, equipment, or vehicles along the roadway shoulders within 100 meters of Stack Rock Creek Bridge. • Best management practices will be used to prevent indirect impacts by sedimentation. An erosion and sediment control plan will be prepared and submitted to the North Carolina Department of Environmental Quality for review and approval. The following conservation measures for the Bog turtle were recommended but are not subject to Section 7 consultation: Page 4 of 10 EFLHD NEPA Categorical Exclusion Form EFL-TM-ENV-03(04) BLRI 2B 13-2H 17 0 Eastern Federal Lands Highway Division U.S.Department g y of Transportation NEPA Categorical Exclusion Form Federal Highway Administration • Avoid soil disturbance, excavation, or other activities that could impact wetland hydrology adjacent to and within bog turtle wetlands. • If possible, conduct work adjacent to/within bog turtle wetlands during the bog turtle hibernation period which is November 1 to February 28/29. • Use best management practices (BMPs) to avoid the spread of invasive plants into wetlands. • Where road work bisects known bog turtle habitat, attempt to include bog turtle passageways or retrofit existing culverts in a manner that will allow for bog turtle passage to connect habitat and reduce road mortality. All bridges, culverts and other roadside features will be repaired or replaced in kind to match the historic character of the roadway. Summary of Section 7 of the Endangered Species Act Compliance FHWA obtained an official species list using the USFWS Information for Planning and Consultation (IPaC) website in March 2021. The query resulted in the identification of fourteen species (See Appendix A). FHWA initiated consultation with the USFWS in May 2021. The initial contact included a project description, GIS data, and preliminary conclusions. FHWA and NPS also requested any additional conservation measures, recommendations, or other feedback. On June 7, 2021 USFWS submitted a response that included numerous recommendations for the project and requested the preparation of a Biological Evaluation. A draft version of the Biological Assessment was submitted to USFWS on July 9, 2021. FHWA received comments from USFWS and provided a final revision on July 29, 2021. The Biological Assessment contains numerous conservation measures as described in the Environmental Commitment section above. The BE contains the following conclusion: • Based on the results of this evaluation, FHWA and NPS have determined the project would have no effect on the following seven federally regulated species: Spruce -fir Moss Spider (Microhexura montivaga); Blue Ridge Goldenrod (Solidago spithamaea); Dwarf -flowered Heartleaf (Hexastylis naniflora); Heller's Blazingstar (Liatris helleri); Roan Mountain Bluet (Hedyotis purpurea vor. montana); Spreading Avens (Geum radiatum); and, Virginia Spiraea (Spiraea virginiana). The project would also have no effect on the at -risk Golden Winged Warbler (Vermivora chrysoptera). A may affect, not likely to adversely affect determination has been reached for six federally regulated species including the Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus), Gray Bat (Myotis grisescens), Northern Long-eared Bat (Myotis septentrionalis), Virginia Big -eared Bat (Corynorhinus/Plecotus townsendii virginianus), Swamp Pink (Helonias bullata), and Rock Gnome Lichen (Gymnoderma lineare). The project may affect Page 5 of 10 EFLHD NEPA Categorical Exclusion Form EFL-TM-ENV-03(04) BLRI 2B 13-2H 17 0 Eastern Federal Lands Highway Division U.S.Department g y of Transportation NEPA Categorical Exclusion Form Federal Highway Administration but is not likely to adversely affect three at -risk species including the Carolina Hemlock (Tsugo caroliniana), Tricolored bat (Perimyotis subflavus), and Little Brown Bat (Myotis lucifugus). On August 10, 2021, USFWS concurred with the FHWA conclusions. The concurrence is contingent upon numerous conditions specified in the Biological Assessment. Summary of Section 106 of the National Historic Preservation Act Compliance NPS is the lead federal agency for Section 106 compliance. On July 13, 2021, NPS sent a consultation letter to the North Carolina State Historic Preservation Office (SHPO) containing the following assessment: The area of potential effects (APE) for this project includes the area that would be directly impacted by road maintenance (Sections 2B, 2C, 2D, 2E, 2F, 2G, and 2H), as well as the area from which the maintenance activities would be visible and audible. Historic properties within the APE include the National Register of Historic Places (NRHP) eligible Blue Ridge Parkway Historic District (BN0905), and its contributing features of bridges, culverts, and landscaping, that are located within the Sections listed above. Several sections of the parkway and its contributing features of bridges, culverts, and landscaping will all be included as elements of this proposed project. The park has been working closely with the NCSHPO office, and through that consultation notes that the proposed work will not rise to the level of causing an adverse effect to the parkway. An NPS archeologist evaluated the project APE and does not anticipate any effects to unidentified cultural resources. Blue Ridge Parkway and NPS Southeast Regional Office subject matter experts have reviewed this project and determined it would have no adverse effect on the Blue Ridge Parkway Historic District. The SHPO concurred with the NPS determination in a letter dated August 20, 2021 (SHPO file ER-21-1921). Additional Agency Coordination and Compliance NPS and FHWA are preparing concurrent NEPA documentation. The NPS environmental/PEPC review file PIN 102368 contains additional documentation and analysis. A wetland and Waters of the US survey is currently being conducted. Any work that would result in wetland/stream impacts will require Clean Water Act, Section 404 and 401 permits Erosion and Sediment Control plan review is required. This may require a Trout Buffer Waiver, and other state permitting. An NPDES permit will be required.

Dear Mr. Kimberley: On July 16, 2021, we received (via email) your information requesting our comments on the subject project. Comments in response to a scoping request were provided on June 7, 2021. We have reviewed the information that you presented and the following comments are provided in accordance with the provisions of the National Environmental Policy Act (42 U.S.C.§ 4321 et seq.); the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661 - 667e); the Migratory Bird Treaty Act, as amended (16 U.S.C. 703); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 - 1543) (Act). Proiect Description According to the information provided, the National Park Service, Blue Ridge Parkway (BLRI) and Federal Highway Administration (FHWA) have received funding through the Great American Outdoors Act to rehabilitate approximately 76 miles of the BLRI motor road in Alleghany, Ashe, Avery, Caldwell, Watauga, and Wilkes Counties (Sections 213-21-1, Milepost 229.6 — 305.1). The primary objective of the project is to improve the condition and extend the pavement life of the motor road in North Carolina Sections 213-21-1. The proposed project involves pavement and drainage improvements including culvert repair, culvert replacement, scour repair, and other rehabilitation activities. Ground disturbance, stream and wetland impacts, and vegetation removal will occur. Your information did not include specific information or details regarding construction plans, permitting, or construction timelines; however, additional information was provided during email correspondence from May 14 — 20, 2021. A culvert assessment identified 302 culverts needing repair due to poor (119), critical (47), or unknown (118) condition and/or performance problems (18). Additionally, 28 bridges were identified as needing repair (26) and/or full deck replacement (2). The following additional project details were provided: Mr. Kimberley — FHWA 2 The proposed project will include repairs to the roadway, bridges, culverts, and access to structures for repairs. In some places, rehabilitation activities could extend beyond the motor road. The full scope of work includes: o Heavy 3R (resurfacing, restoration, and rehabilitation). o Light 3R (edge erosion rehabilitation, pavement marking, crack sealing, light pavement patching). o Signage and pavement markings improvements for sight and distance aimed at enhancing safety. o Shoulder stabilization with aggregate topsoil and turf establishment or geogrid pavers. o Stone curb removal and resetting. o Asphalt sidewalk reconstruction at overlook parking areas. o Guardrail and stone guardwall repair and reconstruction. o Drainage work includes inspecting and evaluating culverts, headwalls, inlets, ditches, and outfalls for needed cleaning, reconditioning and replacement. This activity may include vegetation removal for access and maintenance of structures. o Minor bridge repairs including the following types of repairs: ■ cleaning and repointing stone masonry; ■ cleaning and resealing deck joints and vertical joints; ■ installing object markers and clearance signs; ■ cleaning and sealing concrete decks; ■ repairing minor damage to concrete; ■ milling and overlaying; ■ waterproofing membranes; ■ structural concrete crack injection; ■ removing graffiti; ■ repairing broken utilities; ■ cleaning and painting structural steel; ■ repairing bridge rails; and ■ miscellaneous grading and erosion repairs. Federally Listed Species An assessment of suitable habitat and potential impact to 18 species was conducted by environmental specialist with the BLRI and FHWA in June of 2021. The findings were compiled and included in the "FHWA Project BLRI 2B13-2H17, Blue Ridge Parkway Rehabilitation, Biological Evaluation, Revision #l" (biological evaluation) submitted to our office on July 16, 2021. The following species and their associated habitats were evaluated: Mr. Kimberley — FHWA 3 Species Protection Status'> Status of Occurence' Blue Ridge goldenrod Solidago spithamaea T C P C Bog turtle Glyptemys muhlenbergii T(S/A) C C C C C C Carolina Hemlock Tsuga caroliniana ARS C C Carolina northern flying squirrel Glaucomys sabrinus coloratus E C C C C Dwarf -flowered heartleaf Hexastylis naniflora T C Golden -winged warbler Vermivora chrysoptera ARS C C C C Gray bat Myotis grisescens E P C C P P P Heller's blazing star Liatris helleri T C C C C Little brown bat Myotis lucifugus ARS P C C P C C Northern long-eared bat Myotis septentrionalis T C C C C C C Roan mountain bluet Hedyotis purpurea var. montana E C C C C Rock gnome lichen Gymnoderma lineare E C C Spreading avens Geum radiatum E C C P C Spruce -fir moss spider Microhexura montivaga E Ccx CcH Ccx Swamp pink Helonias bullata T C Tricolored bat Perimyotis subflavus ARS P P C C C C Virginia big -eared bat V Corynorhinus townsendii vir inianus E C C C Virginia spiraea Spiraea virginiana T C ' E = endangered, T = threatened, T(S/A) = threatened due to similarity of appearance, ARS = at -risk species, and CAN = candidate species. 2 C = current, P = potential, and CCH = current and county includes critical habitat. The biological evaluation states that no suitable habitat is present in the proposed project area and will therefore have no effect on the following species: Blue Ridge goldenrod, dwarf - flowered heartleaf, golden -winged warbler, Heller's blazing star, Roan Mountain bluet, spreading avens, spruce -fir moss spider, and Virginia spiraea. Based on the information provided, we agree with this assessment. Bog turtle is federally listed as threatened (due to similarity of appearance) and is not subject to section 7 consultation; however, it is a species of concern for our office. If bog turtles or suitable habitat is identified within the proposed project area or proposed activities will impact hydrology of suitable habitat (i.e. changing drainage patterns to/from wetlands), the BLRI and FHWA have agreed to coordinate the project with the U.S. Fish and Wildlife Service (Service) and the NC Wildlife Resources Commission and implement the following general recommendations to the extent practicable: • Avoid soil disturbance, excavation, or other activities that could impact wetland hydrology adjacent to and within bog turtle wetlands. Mr. Kimberley — FHWA 4 • If possible, conduct work adjacent to/within bog turtle wetlands during the bog turtle hibernation period which is November 1 to February 28/29. • Use best management practices (BMPs) to avoid the spread of invasive plants into wetlands. • Where road work bisects known bog turtle habitat, attempt to include bog turtle passageways or retrofit existing culverts in a manner that will allow for bog turtle passage to connect habitat and reduce road mortality. The Service can provide BMPs for turtle passageways. Suitable habitat for Carolina northern flying squirrel (CNFS) may exist along the BLRI motor road between Milepost 300-305 (Grandfather Mountain corridor). The following conservation measures will be implemented within the Grandfather Mountain corridor to avoid and minimize potential impacts to the species: • No night work will occur. • In coordination with the BLRI and FHWA, all trees proposed for cutting or trimming will be marked by the contractor and inspected by a qualified biologist. The biologist will: o Inspect marked trees to determine species and suitability for dreys and/or denning. o If suitable trees are identified and cannot be avoided, the biologist will inspect accessible cavities visually and with a peeper scope for evidence of CNFS use. Any trees containing evidence of use will not be removed. o Direct contractors to avoid: ■ Trees with cavities (e.g., old gnarly trees, snags, trees with woodpecker holes or rotted knotholes). ■ Cutting yellow birch (Betula alleghaniensis) greater than 8 inches in diameter at breast height when possible, especially in mixed stands where yellow birch is limited. ■ Cutting red spruce (Picea rubens), fir (Abies fraseri), and hemlock (Tsuga spp.) unless they are posing a threat to the stability of the motor road or associated drainage features. ■ Cutting trees that would create large canopy gaps along the road. If gaps greater than 40 feet wide are created, a large tree will be retained for a CNFS launch point. • Tree removal will occur outside of the CNFS maternity season (March 15 — August 30) when CNFS could have pups. • Contractors will be informed of the potential presence of CNFS. If flying squirrels of any type are observed by the contractor, all work in the area will stop and the contractor will notify and contact the BLRI, FHWA, and Service immediately for further guidance. Suitable occupied habitats for gray bat, northern long-eared bat, Virginia big -eared bat, little brown bat, and tricolored bat occur throughout the entire 76-mile project corridor. The following conservation measures will be implemented along the project corridor to avoid and minimize potential impacts to these species: • No tree removal will occur between March 15 and November 15 when bats could be present on the landscape (except as noted below). Mr. Kimberley — FHWA • If bridge, culvert, or guardwall (structure) work needs to occur between March 15 and November 15, a qualified biologist will inspect structures for evidence of bat use prior to construction. • Inspections will follow the Indiana State University Manual for Determining Bat Presence. The manual will be provided to the qualified biologist preforming inspections. • Inspections will occur as close to the beginning of work as possible and within two weeks of construction activities beginning. • A structure assessment form approved by the BLRI and Service will be used to document inspections. • All bridges will be inspected. • All culverts over 2-feet in diameter, regardless of material, will be inspected. If culverts are big enough to walk through, a qualified biologist will walk the length of the culvert. • All guardwalls or retaining walls with cracks and crevices large enough to provide habitat for bats will be inspected. • If evidence of bats is seen: o The BLRI or FHWA will notify the Service immediately to discuss appropriate avoidance measures. No work will begin at the structure location until discussions with the Service have concluded. o The preferred avoidance measure is waiting for bats to leave for the season and delaying work until construction can be complete between November 16 and March 14. If this cannot occur, the BLRI and FWHA will reinitiate consultation with the Service to assess impacts of the proposed activity and determine additional conservation measures. o Regardless of when work is done, if bat use is observed, ensure habitat remains after the structure is repaired so bats can return the following season. • If evidence of bats is not found during the inspection of a structure, but evidence or bat sightings are unexpectedly made during construction, the contractor will stop work and the BLRI and FHWA will notify the Service immediately. No work will resume at the structure location until discussions with the Service have concluded. • Complete structure assessment forms will be provided to the BLRI and FHWA by the contractor monthly or within one business day of encountering evidence of bats. The BLRI will compile the forms and submit them to the Service every 90 days, or when bats are documented, whichever is sooner. Suitable occupied habitat for swamp pink occurs downslope of the project area between Milepost 248 and 249. The following conservation measures will be implemented in that 1-mile corridor to avoid and minimize potential impacts to the species: • No materials, equipment, or vehicles will be staged along motor road shoulders. • BLRI staff will monitor hydroseeding and turf establishment activities within 100 meters of the known population to ensure that fescue or other seeds are not applied outside of motor road shoulders. • Best management practices will be used to prevent indirect impacts from sedimentation. This will include the use of fiber rolls and/or filter berms. An erosion and sediment control plan will be prepared and submitted to the North Carolina Department of Environmental Quality (NCDEQ) for review and approval. Mr. Kimberley — FHWA 6 Suitable occupied habitat for rock gnome lichen occurs in Stackrock Creek beneath the motor road bridge at Milepost 304. The following conservation measures will be implemented in this location to avoid and minimize potential impacts to the species: • There will be no direct impacts to Stackrock Creek. • No materials, equipment, or vehicles will be staged along motor road shoulders within 100 meters of the Stackrock Creek bridge. • Contactors and equipment will not enter the stream channel and construction debris will be contained/secured on the bridge deck until removal. Debris will be removed at the end of each workday. • Best management practices will be used to prevent indirect impacts from sedimentation. An erosion and sediment control plan will be prepared and submitted to the NCDEQ for review and approval. BLRI staff have not identified Carolina hemlock along the motor road but will notify the Service if trees are identified during marking of trees for removal. If Carolina hemlock is observed within the Grandfather Mountain corridor, the trees will not be cut unless they are posing a threat to the stability of the motor road or associated drainage features. If Carolina hemlock is observed outside the Grandfather Mountain corridor, the BLRI and FHWA will contact the Service for guidance. No work will resume at the structure location until discussions with the Service have concluded. The BLRI and FHWA have determined that the project "may affect, but is not likely to adversely affect" (MANLAA) the following federally listed species: CNFS, gray bat, northern long-eared bat, Virginia big -eared bat, swamp pink, and rock gnome lichen. Based on the information provided and the commitment to implement the above conservation measures, we concur. The BLRI and FHWA have determined that the project MANLAA the following federally at -risk species: Carolina hemlock, little brown bat, and tricolored bat. Based on the information provided and the commitment to implement the above conservation measures, we concur. In order to avoid the disruption to ongoing or planned actions, the Service recommended conferencing for these species to facilitate the impact analysis included in the biological evaluation. The conference can be adopted as concurrence if a final rule for these becomes effective during the life of the project. We believe the requirements under section 7 of the Act are fulfilled for the federally listed species discussed above. However, obligations under section 7 of the Act must be reconsidered if. (1) new information reveals impacts of the identified action may affect listed species or critical habitat in a manner not previously considered, (2) the identified action is subsequently modified in a manner that was 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. Fish and Wildlife Resource Recommendations We are also concerned about the potential effects the proposed project could have on other natural resources within and surrounding project area. The general recommendations for the benefit of fish and wildlife resources, outlined in our June 6, 2021 scoping letter, remain relevant to the proposed project. Mr. Kimberley — FHWA 7 The Service appreciates the opportunity to provide these comments. Please contact Ms. Rebekah Reid of our staff at rebekah_reid@fws.gov, if you have any questions.

I am familiar with the wildlife resources in the area but did not visit the project sites. Comments on the application from the North Carolina Wildlife Resources Commission (NCWRC) are offered to conserve wildlife resources affected by the project and to promote wildlife -based recreation in accordance with applicable provisions of the state and federal Environmental Policy Acts (G.S. 113A-lthrough 113-10; 1 NCAC 25 and 42 U.S.C. 4332(2)(c), respectively), the Clean Water Act of 1977 (33 U.S.C. 466 et seq.), and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). The project will impact Little Glade, Brush, Bullhead, Garden, Waterfall, Meadow Fork, Pike, and Little Fork creeks, or their unnamed tributaries, in Alleghany and Wilkes counties. Most of the work will involve channel dewatering and excavation of accumulated sediments in the vicinity of culverts that pass under the parkway or connecting roadways.

The NCWRC supports the conservation measures outlined in the consultation information that was included with the application. Some of the affected streams are small, first order tributaries that are likely fishless. However, others support wild trout populations at or short distances downstream of the impact sites. The NCWRC requests that the October 15 to April 15 moratorium for work in all streams and buffers be adhered to, as proposed, because there are naturally reproducing trout at or downstream of several project sites. In addition to the moratorium, effective sediment and erosion controls will be needed and work should be performed steadily within jurisdictional areas to minimize the potential for downstream sedimentation. Sedimentation, if it occurred, could be extensive because the sites are situated near the headwaters of these stream systems. The NCWRC emphasizes that overly widening or deepening of channels and the elevating of culvert outlets (aka perching) should be avoided. While the intent of the work is to restore hydraulic capacities of drainage structures, it is nonetheless important to balance that objective with the natural functions of these systems, including aquatic life support and sediment transport. Therefore, to the extent possible, excavation should mimic stable or reference channel dimensions that are expected for the size of the streams. Unless already otherwise addressed, these expectations should be included as special permit conditions. And, they should be communicated to construction staffs, particularly in maintenance situations where detailed work plans may not be prepared. Thank you for the opportunity to review and provide recommendations on this project. Please contact me at david.mchenrygncwildlife.org or (828)476-1966 if you have any questions about these comments.

To: McHenry, David G Subject: RE: [External] FW: Blue Ridge Parkway culvert maintenance project Date: Monday, November 14, 2022 8:33:32 AM Good morning Dave, Hope you are doing well and had a great weekend. Thank you for your questions. No, none of the pipes are being replaced. The maintenance work involves repairing headwalls where needed and sediment & debris removal. The pipes are in good shape. I guess they built things better back in the 1930's. One thing is for certain, the concrete from back then is more durable than what they pour now. Also, NPS does not clear snow on this section of the parkway. When it snows or iced over, they close the parkway. Therefore, no salt or other ice clearing chemicals are used on the parkway. I think that might have something to do with the condition of the concrete pipes. The plan is to submit the ePCN this week, hopefully by Wednesday. Thank you for your prompt response to our request.

Do not click links or open attachments unless you recognize the sender and know the content is safe. I was wondering about that. Thanks for the clarification. Are the pipes being replaced, or are just headwall repairs planned along with some sediment removal? I reviewed all the sites with GIS and sent the information to our fish biologist for review last Wednesday. BTW you can go ahead and submit the ePCN without including comments from NCWRC. Typically, in practice, the ePCN itself serves as the NCWRC notice for NWP/GPs (we receive them automatically) and then we respond to the project proponent, Corps, and DWR concurrently on any submittal. Advance coordination is typically not needed with more routine stuff like maintenance, but it is certainly appreciated. I don't anticipate commenting anything unusual on this project, just routine measures such as minimize excavation to avoid culvert outlet perching/channel destabilization, work in the dry, adhere to moratorium, etc...

I sent you this email earlier this week requesting NC WRC comment on project Trout waters in Alleghany and Wilkes Counties associated with the referenced project as is required by the regional conditions of USACEW Nationwide Permits. Since the email I have discovered an error in the impact summary table of the permit plan. The stream channel work involves repair of headwalls and removal of sediment & debris from the existing culverts. The stream channel impacts in the summary were listed wrong as permanent, while the impacts are temporary. There is no net lost of stream channel or stream channel function. I have attached a revised table. Please provide me your questions and comments. I am hoping to submit the ePCN first of next week and would appreciate your prompt response to our request.

As discussed, the National Park Service Blue Ridge Parkway (BRP) with Federal Highways Administration (FHWA) as the lead federal agency is proposing mill and fill re -pavement and some culvert maintenance (i.e., repair headwalls and cleaning sediment/debris from existing culverts) to 20 culverts on USACE determined jurisdictional stream channels on the BRP. The project begins at US 21, Roaring Gap, Alleghany County and ends at US 421, Deep Gap, Watauga County. FHWA completed a NEPA Categorical Exclusion for the project that included formal consultations with the Fish and Wildlife Service (FWS) that resulted in FHWA commitments to conservation measures to mitigate potential impacts to Sec. 7 Threaten and Endangered species and with State Historic Preservation Office to address Sec. 106 concerns. FHWA also has been in consultation with USACE and NC DENR for Sec. 404 permitting, Sec. 401 State Water Quality Certification and State Land Quality stormwater/erosion control permitting. We are currently working on the ePCN applications for the project. I have attached a vicinity map and a permit plan (includes JD impact table and typical dewatering plan for culvert work) for your review for comments for Trout Waters in Alleghany and Wilkes Counties. The FHWA project contract conditions include requirement for contractor to observe the Oct. 15th to April 15th Trout Moratorium and I anticipate the Trout Moratorium will be special condition to the Sec. 404 and Sec. 401 project authorizations. The purpose of this email is to request NC Wildlife Resources Commission comments as required by Sec. 404 Nationwide Permit Regional Conditions for temporary impacts to NC Trout Waters in Alleghany and Wilkes County. Please let me know if you have any questions or need any additional information for your comments.
