NCWRC staff visited the site on November 7, 2019. Our comments on this application are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). These comments are based on information about the project received with the Pre-construction Notification received on 11/13/2019, revised plan documents and email dated 1/6/2020, and a draft Biological Assessment dated 1/16/2020. Project activities should not impact wild trout and do not need to be avoided during a trout moratorium. However, the French Broad River at this location supports Appalachian Elktoe (Alasmidonta raveneliana, US & NC Endangered), Creeper [Strophitus undulatus, NC Threatened (T)], and possibly Eastern Hellbender [Cryptobranchus alleganiensis, US Federal Species of Concern, NC SC (Special Concern)]. Gray Bat (Myotis grisescens, US & NC Endangered) is found in the project area, and Northern Long-eared Bat (Myotis septentrionalis, US & NC Threatened), Bog Turtle (Glyptemys muhlenbergii, US Threatened due to Similarity of Appearance, NC T), and Mudpuppy (Necturus maculosus, NC SC) may occur in the project vicinity. The French Broad River supports a Muskellunge (Esox masquinongy), Smallmouth Bass (Micropterus dolomieu), and Redbreast (Lepomis auritus) fishery, and NCWRC is beginning a 5-year Muskellunge population study. Activities involved with this project have the potential to directly and indirectly impact these species, and we provide a number of Project Ranger Page 2 January 31, 2020 French Broad R & wetland, Buncombe Co recommendations to minimize these impacts as well as conserve or create habitat for these species. The project involves the construction of a 610-ft long 5-lane bridge across the French Broad River, approximately 1000 ft downstream of the Blue Ridge Parkway bridge. This new bridge will lead to a road that will be constructed to access an industrial site. Total limits of disturbance are estimated to be 84 acres, with 80 acres of tree clearing. Components of this project include the following:  The bridge would have two bents, with 5 pilings each, and allow 20-30 ft of clearance above the water surface. Installation of the bridge footings will involve drilling in the riverbed, and bent installation may require pile-driving. In order to construct the bridge, temporary rock causeways of Class II riprap would be constructed along both banks of the river in two phases. Phase 1 would involve dual 114 ft causeways running parallel to river flows, extending 80 and 70 ft into the river from the west and east banks, respectively, and filling 0.34 acre for 12 months. Phase 2 would extend the Phase 1 causeways by 24 ft in length (parallel to flows) and 40 ft in width (each). Phase 1 causeways would be in place for 12 months, and Phase 2 causeways would be in place for 1 month of that time. During Phase 1, 37% of the river width will be blocked, but during Phase 2, 64% of the river will be blocked. A river safety plan to warn approaching river users has been developed.  In order to comply with Federal Emergency Management Agency no-rise requirements, the applicant proposes to clear riparian forest along 270 ft (1.3 acres) of the west bank and 260 ft (1.7 acres) of the east bank. It is unknown if any of this area will also be excavated, and if so, if what means will be used to stabilize the area. An additional 3 acres of trees will be cleared in the vicinity of the bridge to accommodate excavation and bridge construction. Excavation will not extend to the water’s edge. Banks would be stabilized with riprap along 114 ft under the bridge. Tree clearing will be avoided during the bat maternity season of May 15 to August 15.  Drainage from the bridge would be directed west to grated inlets installed off the bridge and discharged onto riprap dissipater pads at least 50 ft from the river. It is possible that a deck drain system will be used to reduce stormwater spread on the bridge, and this would be discharged on riprap dissipater pads at least 30 ft from the river. After leaving pads, stormwater would be dispersed as sheet flow and infiltrate through vegetated areas.  0.067 acre of wetland would be impacted for bridge construction.  The bridge would connect NC 191 with a new road on Biltmore Farms property. This road would be cleared and graded to accommodate a four-lane road, with only a two-lane road being constructed initially.  The road would lead to an industrial facility that will be approximately 750,000 ft2 (17.2 acres) with possible future expansion areas, which will be cleared and graded in association with the initial phase of work. Parking for approximately 1,200 employees will be provided, with 617 parking spaces provided initially; future parking is proposed to include another 532 spaces. Blasting (60 total blasts) may occur for site development for approximately 6 months.  Old River Road on the Biltmore Farms property will be used to access the construction area from Schenk Road, and an additional gravel road that crosses under the Blue Ridge Parkway would also be used. The footprint of the roads will not be widened, but trees may be cleared along the edges of the road to facilitate equipment movement. Existing culverts will not be lengthened. Project Ranger Page 3 January 31, 2020 French Broad R & wetland, Buncombe Co  The proposed impervious area will be 41.6 acres for the manufacturing facility and parking areas, bridge, access road and round-about, including future expansion areas. The 445-acre tract will be 9% impervious.  Sediment and erosion control measures will be designed for the 25-year storm. Permanent post-construction stormwater management will treat the 1-year 24-hour storm event, and the rate of discharge will not exceed the pre-development rate for this storm event. Two stormwater ponds will be built at the development site, with outlets directed away from wetlands. Velocity control measures will be designed to limit scour and erosion at the pond outlets. The applicant is working with US Fish and Wildlife Service (USFWS) through the Biological Assessment process. Conservation measures are in development to avoid/minimize effects and to partially offset anticipated effects to federally listed species, particularly Gray Bat, Northern Long-eared Bat, Bog Turtle, and Appalachian Elktoe. Among the conservation measures being discussed are construction specifications to limit percussive and light impacts to bats, permanent lighting specifications, erosion control specifications, bat roost paneling and monitoring on the new bridge, and conservation funding for Appalachian Elktoe. We offer the following recommendations to minimize impacts to fish and wildlife resources: 1. Work should be accomplished as quickly as possible and vigilance used in sediment and erosion control during site preparation, construction, and clean up. Due to the presence of listed species in the French Broad River, we ask that disturbed areas be stabilized on a tight timeframe to minimize risk of sediment loss, namely, the disturbed areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of each work day; at a minimum, disturbed areas should be stabilized within five working days or seven calendar days, whichever is shorter. This tighter stabilization timeframe is of particular importance in riparian areas and along stream banks. 2. Seeding specifications have not been provided. Seeding mixes should not include invasive species, such as Tall Fescue and Sericea Lespedeza. Permanent seed mixes should be comprised of native grasses and forbs. An emphasis on pollinator-beneficial species should be made. 3. Any erosion control matting used should be free of plastic or nylon mesh, as this type of mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years. 4. We request detailed information (including maps) on the area of riparian clearing and excavation, as well as information on how excavated areas will be stabilized. 5. Drilling within the riverbed involves a risk of frac-out. We request that the applicant develop a frac-out contingency and containment plan. 6. Effective stormwater management is essential in minimizing impacts to downstream waters. Instead of the stormwater management measures proposed (two large ponds), we recommend the use of Low Impact Design techniques, such as grassed swales and pervious pavement; curb and gutter, catch basins, and underground piping of stormwater should be avoided. As stormwater runoff from pavement can cause short-term temperature spikes in downstream waters, mechanisms to lower stormwater temperature should be incorporated into the stormwater management design. Project Ranger Page 4 January 31, 2020 French Broad R & wetland, Buncombe Co 7. We are concerned about the erosive capacity of stormwater from the bridge and the development. Although velocity control measures will be designed to limit scour and erosion at the pond outlets at the industrial site, we are concerned about scour and erosion downstream of the pond outlets and ask the applicant to provide additional details as to how this will be avoided. 8. We request that NCWRC and USFWS biologists be allowed on the Biltmore Farms site in order to monitor rare and listed species, in particular bog turtles, gray bats, listed salamanders, and birds. We recommend that Biltmore Farms, NCWRC, and USFWS develop an agreement to allow periodic and long-term access to the site. 9. There are several large wetlands within the larger French Broad River floodplain on the Biltmore Farms site that provide habitat for Bog Turtle, Mole Salamanders, and other rare and/or listed species. We strongly recommend that conservation easements be established on these ecologically important sites. 10. We support the discussions being held between the USFWS and the applicant to develop conservation measures to minimize impacts to and benefit the Gray Bat. We appreciate the applicant’s willingness to install bat panels, support monitoring of bat populations during the project, limit percussive activities, and minimize light pollution within the river corridor and at the industrial area. 11. The project will eliminate riparian habitat along almost 300 ft of the French Broad River. Riparian forest is important in maintaining bank stability, treating surface water pollutants, slowing flood stage flows, moderating river temperature, and providing in-stream habitat. For the Gray Bat, this forested riparian area is also an important habitat, as gray bats fly along river banks within the shelter of the trees. We ask that riparian clearing be minimized as much as possible and large trees along the river’s edge be left to retain some habitat for bats and provide some of the functions of riparian habitat. 12. If possible, any in-channel work should avoid disturbing large flat rock that could serve as hellbender shelters. 13. We ask that the applicant notify NCWRC biologists Lori Williams (lori.williams@ncwildlife.org) and Luke Etchison (luke.etchison@ncwildlife.org) at least 2 weeks before any in-channel work begins.

If either of these conditions are reported and confirmed, operations are to immediately cease and not to resume until cleanup procedures are complete and appropriate agencies have been notified. Containment and removal of drilling fluid releases to the surface from an inadvertent release of drilling fluids will be performed where practical and where there will be a net benefit in the reduction of total environmental impacts. Process of Mitigation Before the drilling occurs: 1. Notification will be sent out to Biltmore Farms upon completion of each drill and starting date for the next drill. Biltmore Farms will then notify the Army Corps of Engineers, the Division of Water Resources, and US Fish and Wildlife Service. 2. Silt fence will be installed around perimeter of the drill location. 3. The Contractor will hold meetings with workers involved to explain how to handle a fluid loss situation. In the event of a fluid loss the contractor will visually check the surface to determine location and handle accordingly: 1. Underwater a) A monitor will be on site at all times during drilling to continuously search visually for observable frac‐outs. The HDD operator will continuously monitor the pressure readings on the machine. A loss in pressure will indicate a loss in fluid; however, that does not specifically mean the material is being released into the stream. • The Bore‐Gel (a mixture of bentonite and water) may congeal the frac-out, which means that it will harden in the fractures of the rock and prevent the material from reaching the surface water. • If pressure loss is observed, we will stop the operation temporarily and monitor to see if Bore‐Gel hardens and plugs the leak. b) If/when a fluid loss is observed the contractor will temporarily suspend the drill and add a polymer to help seal the fracture. c) Upon the stoppage of the fluid loss the contractor will pump out the containment area to the best of our ability and take back to the recycler. 2. On Ground a) A monitor will be on site at all times during drilling to continuously search visually for observable frac‐outs and the HDD contractor will continuously monitor pressure readings. b) Immediately install silt fence around area of fluid loss to contain and then start pumping the bore‐gel back to machine. c) Remove deposited Bore‐Gel offsite (if any). d) Regrade areas of Bore‐Gel deposition to original slope and contour. e) Reseed impacted area. Any material that can be safely and can be cleaned up via vac truck will be done so. A vac truck will be on‐site in event to help minimize a release and assist in containment. An alternative approach if a frac‐out occurs would be to pull the drill and attempt a second shot; however, this could force a second release of fluid and additional impacts. Therefore, if Bore-Gel has sealed the initial frac-out and there is no threat to public health or significant impacts to sensitive environmental areas, drilling will continue at the initial location, which will minimize the frac‐out’s impacts (both extent and duration). In the event of a frac‐out, the contractor will notify the Biltmore Farms immediately following detection. Biltmore Farms will then contact the Army Corps of Engineers, the Division of Water Resources, and the US Fish and Wildlife Service. Once contact has been made, the contractor will take the appropriate action specified above. All effort will be put forth to mitigate the fluid losses and if further measures are deemed impractical due to actual environmental impacts, the drilling will be completed as soon as possible. In the event of fluid loss whether underwater or terrestrial, all environmental protection measures will stay in place until the fluid loss has stopped. Once the frac‐out has stopped, an incident report will be filled out and documented with pictures before, during and after cleanup. This report will detail the time, place, and measures taken to stop the frac‐out. This report will be furnished to Biltmore Farms, the Corps of Engineers, Division of Water Resources, and the US Fish and Wildlife Service no later than 10 days following the incident. Upon completion, the Bore‐Gel will be pumped to a holding tank and stored, until it is disposed of offsite. Being an inert material, it does not require treatment prior to disposal.

These signs will note that the last public pull out is at Bent Creek River Park, 400 feet upstream of the bridge. These signs will be placed at the following locations; all are public with the exception of the privately owned launches marked with an asterisk (*):  Headwaters Outfitters* – 25 Parkway Road, Rosman  Champion Park River Access (Transylvania County Parks and Recreation) – Old Turnpike Road, Rosman (1st public access from the headwaters)  Hannah Ford Campground - Headwaters Outfitters* - Green Road (SR 1127), Rosman  Island Ford River Access (Transylvania County Parks and Recreation) – Island Ford Road, Brevard  Hap Simpson Park (Brevard Parks and Recreation) – 968 Greenville Hwy, Brevard  Wilson Road River Access (Transylvania County Parks and Recreation) – Wilson Road, Pisgah Forest  Penrose Boat Ramp (NC Wildlife Resources Commission) – 170 Apac Drive, Penrose  Blantyre Park (Henderson County Parks and Recreation) – 500 Cliff Road, Penrose  Horse Shoe River Access Park (Henderson County Parks and Recreation) – Horse Shoe  Westfeldt Park (Henderson County Parks and Recreation) – 83 Old Fanning Bridge Road, Fletcher  Glen Bridge River Park (Buncombe County Parks and Recreation) – 77 Pinners Road, Arden  Corcoran Paige River Park (Buncombe County Parks and Recreation) – 9Pinners Road, Arden  Bent Creek River Park (Buncombe County Parks and Recreation) – 1592 Brevard Road, Asheville  Zen Tubing* - 1648 Brevard Road, Arden  Hominy Creek River Park (Buncombe County Parks and Recreation) – 194 Hominy Creek Road, Asheville  Asheville Outdoor Center* - 521 Amboy Road, Asheville  French Broad Outfitters* - 704 Riverside Drive, Asheville  Mills River Park (Town of Mills River) – 124 Town Center Drive, Mills River (This park is near the confluence of Mills River and French Broad River and a common starting point for paddlers of the French Broad River.) o Signage on the causeways to warn river users away and prevent river users from using the causeway as a stopping point. • Physical restrictions o Use of a floating navigational aide to mark the safe passage lane. o Effort will be made to prevent construction material from falling on river users during bridge construction. This effort includes placing temporary plywood below bolted splices during girder erection and along the bridge deck exterior. Once girders are in place, continuous stay-in-place metal forms will be installed on top of the girders throughout the bridge deck footprint preventing construction materials from falling below. o Steady-state red lights that are solar-powered will be placed on the causeway to alert river user to its location. Generators will not be used to provide power. These lights will be atop permanent structures, such as a pole, on each causeway for the duration of the project. The contractor will be responsible for maintaining these lights at all times during construction, replacing them as necessary. • Contractor requirements: o Develop a river traffic plan to include below items:  Provide one or more flaggers upstream as needed to stop river use at limited times when working over the river (e.g. setting beams)  Training of construction staff to teach skills in aiding a distressed boater – This is meant as an extra precaution for both staff and river users. It does NOT imply that the contractor will provide “lifeguard” type services.  Must have a life vest and/or boat on site.

Although there has been a significant exchange of information and resources between the Service and the Applicant, to date, Biltmore Farms has not disclosed what the proposed 1,000,000 square foot facility would produce, who would operate, or who would employ its estimated 1,200 employees. The Applicant refers to the proposed action as “Project Ranger” and describes it as an economic development project with an extremely sensitive construction schedule. In October and November 2019, the Applicant indicated that the undisclosed industrial developer was considering multiple construction locations throughout the southeastern U.S. It is unclear when, or if the undisclosed industrial developer has committed to development of the project. The USACE initiated informal consultation by email dated November 18, 2019, and the Service has reviewed multiple draft Biological Assessments (BA) since the first was submitted in December 2019. Since then, the proposed project description, conservation measures, and action area have been modified. At this time, the Applicant has accomplished some work for the proposed project including the majority of proposed tree-clearing activities, but the current status of project construction activities is unclear. The USACE accepted the Applicant’s Final BA and initiated formal consultation by email dated May 8, 2020. The list below provides a timeline of some consultation events to date.

INTRODUCTION Biltmore Farms (Applicant) proposes to construct a 1,000,000 square foot undisclosed manufacturing development and appurtenances on approximately 445 forested acres in Asheville, Buncombe County, NC. The Applicant refers to their proposed project as “Project Ranger”. The site is located between Interstate I-26, the Blue Ridge Parkway (BRP), and the French Broad River (Appendix A, Figures 1 and 2). Currently, unimproved roadways (Old River Road) provide limited access to the site from Schenk Parkway and Biltmore Park developments. The Applicant proposes to construct a bridge over the French Broad River located approximately 1,000 feet downstream (north) of the existing Blue Ridge Parkway crossing to provide site access from Brevard Road (NC-191). Certain project details remain uncertain. Biltmore Farms has not disclosed what the proposed 1,000,000 square foot facility would produce or who would employ its estimated 1,200 employees. In October and November 2019, the Applicant described Project Ranger as an economic development project with an extremely sensitive construction schedule but also indicated that the undisclosed industrial developer was considering multiple construction locations throughout the southeastern U.S. It is unclear when, or if, the undisclosed industrial developer has committed to development of the project at the Asheville location. The project description, associated activities, and action area has evolved since the Service reviewed the initial draft Biological Assessment (BA) in December, 2019. The current BA (accepted by the USACE May 2020) indicates that construction activities will begin on August 1, 2020 and take 14 months to complete. However, some project activities (including tree clearing) began in January, 2020 and are nearly complete. This Biological Opinion (BO) considers the effects of the action on the following federally protected species: Appalachian elktoe (Alasmidonta raveneliana), and gray bat (Myotis grisescens, MYGR). 2. DESCRIPTION OF THE PROPOSED ACTION 2.1 GENERAL INFORMATION The proposed project would be located in the Southern Blue Ridge Mountain physiographic region of North Carolina, Buncombe County (Appendix A, Figure 1). Topography in the project vicinity is diverse, composed of steep slopes, rolling intermountain hills, narrow to wide valleys, and flood plains associated with the French Broad River and its tributaries. Elevations in the Action Area range from 1,995 feet above sea level (at French Broad River) to 2,210 feet. The site is located between I-26, the BRP, and the French Broad River (Appendix A, Figures 1 and 2). Site access is currently limited to an existing narrow right-of-way under the BRP and I- 26, Old River Road, and a network of unimproved, unmaintained roadways within the Action 9 Area (Appendix A, Figures 2 and 11). Existing roadways do not provide direct access to the site from Brevard Road (NC-191) that lies west of the French Broad River. To accommodate site access from NC-191, Biltmore Farms proposes to construct a new bridge over the French Broad River approximately 1,000 feet downstream (north) of the existing BRP bridge. The proposed bridge would support up to five lanes of traffic and a pedestrian walkway. By letter dated February 11, 2020, the North Carolina Department of Transportation (NCDOT) expressed their intent to continue coordination with the Applicant and the North Carolina Department of Commerce, and add the new access road and bridge to the state system of maintenance once constructed (Appendix E). 2.2 DESCRIPTION OF THE ACTION AREA The Action Area as defined in 50 CFR 402.02 includes all areas in which federally listed species will be affected by the Proposed Action. Under section 7(a)(2) of the Endangered Species Act (Act), “effects of the action” to be analyzed in this BO are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action. The U.S. Army Corps of Engineers (USACE, Action Agency) indicated on November 18, 2019, that its permit area would include the proposed bridge, entrance road, and building pad site. However, the Action Area considered in the Biological Assessment (BA) is composed of the immediate project footprint, including work areas, staging areas, and access areas, as well as adjacent areas affected by project-mediated disturbances such as light, noise, and vibration. As stated in the BA, the Action Area is larger than the USACE permit area in order to sufficiently encompass all areas that are subject to the effects of the action, that is, all areas where project- mediated impacts to federally protected species may occur. Specifically, the Action Area (Appendix A, Figures 1, 2, 9, 10, 11, 12, and 13) includes the following: • A 445-acre forested tract located north of the BRP, with existing utility easement areas, unimproved roadways, and approximately 7,000 linear feet of French Broad River frontage (primarily right-descending bank); • The construction footprint for the proposed roadway and bridge across the French Broad River including associated clearing, excavation, and grading to satisfy Federal Emergency Management Agency (FEMA) requirements for a “no-rise” certification; • A reach of the French Broad River, 0.25 river miles upstream and 0.5 river miles downstream from riparian areas subject to effects of the action; • A section of Old River Road and adjacent 25-foot wide buffer area (each side) located south of the BRP, extending from Shenck Parkway to the 445-acre tract to be used as a haul road to facilitate site access during construction; • A section of Old River Road and adjacent 25-foot wide buffer area (each side) located north of the BRP, extending from the 445-acre tract to I-26 to be used as a haul road to facilitate site access during construction; and • A section of an unnamed gravel road and adjacent 25-foot wide buffer are (each side) located south of the BRP, extending from Old River Road to the 445-acre tract to be used 10 as a haul road to facilitate site access during construction (includes an easement under the BRP). 2.3 PROPOSED ACTION Certain project details remain uncertain. The Applicant describes Project Ranger as an economic development project with an extremely sensitive construction schedule. The Applicant has not disclosed what the proposed industrial development would produce or who would operate the facility. The Applicant indicates that it will plat and dedicate an 89-acre tract of land for the undisclosed manufacturing facility, but it is unclear when this would occur and who would own this property. According to the BA, the proposed action consists of the design and construction of the following elements: 2.3.1 Proposed Action – Facility Design According to the BA, the Applicant indicates that the proposed project would require approximately a 750,000 square feet manufacturing facility with future expansion plans for an additional 250,000 square feet. The facility footprint would include space for manufacturing, operations, office space, and storage. The expansion areas would be cleared and graded during the initial phase of work (Appendix A, Figures 2, 3, 4, 6, and 7). To accommodate parking for approximately 1,200 employees, project plans provide for 617 parking spaces initially, with expansion potential for an additional 532 parking spaces. The manufacturing facility would be situated on relatively high ground in the western half of the 445 acre tract, between several streams (Appendix A, Figures 3 and 11). The proposed impervious area on the Biltmore Farms Tract north of the BRP will be 41.57 acres for the undisclosed manufacturing facility, parking areas, bridge, access road, and roundabout (including future expansion areas). 2.3.1.1 Facility Design – Permanent Lighting The BA indicates that permanent lighting for Project Ranger would comply with Buncombe County lighting standards, which are intended to minimize light pollution, light trespass and glare, and promote energy efficiency (Buncombe County, 2019). The Project would use warmer color temperature lighting (CCT < 3,000K), utilize LED light fixtures with lumen output equal to or less than Buncombe County requirements, and employ downward-facing fully shielded lighting. The mounting height of all outdoor area lighting would not exceed 25 feet above the lowest adjacent elevation. 2.3.1.2 Facility Design – Stormwater Control Permanent post-construction stormwater control measures will be designed to meet Buncombe County standards which require treatment of the 1-year, 24-hour storm event. County standards also require that the design rate of discharge not exceed the pre-development rate of discharge for this same storm event. To meet these standards, Biltmore Farms proposes to construct two stormwater ponds during the initial phase of construction (Appendix A, Figure 3). These 11 structures are intended to accommodate future site expansion. The outlets for these ponds will be directed away from wetlands and will be located on high ground at least 500 linear feet from the French Broad River. Their discharge will be into non-jurisdictional conveyances that drain into jurisdictional streams. 2.3.2 Proposed Action – Facility Operations Once the undisclosed manufacturing facility is completed in February 2022, traffic in the Action Area will begin as approximately 1,200 employees will travel across the proposed bridge and roadway, daily. Traffic speed on the proposed bridge and roadway would be 35-40 mph and would accommodate approximately 2,000 vehicles per day. Although it is unknown what the facility would produce, the Applicant indicates that deliveries and shipments associated with Project Ranger operations would entail one large transport truck per day. The following activities may be conducted as maintenance of the bridge, access road and the manufacturing facility: pavement maintenance, including patching potholes and cracks; vegetation management including mowing, landscaping, use of herbicides in selected areas, and removal of hazardous trees; winter maintenance, such as plowing, salting, and brining; bridge and facility maintenance; removal of trash; and maintaining ditches and storm water control devices. 2.3.3 Proposed Action – Facility Construction The BA indicates that construction of the undisclosed manufacturing facility would begin August, 2020 and would be completed by February 2022 (Appendix A, Figure 5). However, the Applicant indicated by letter that site preparation and tree clearing activities would begin in January, 2020 (Appendix B; and Section 2.3.3.1 for a description of tree clearing activities associated with facility construction). The construction of the facility would be composed of the following component activities: 2.3.3.1 Facility Construction – Tree Clearing The BA indicates that tree clearing began for Project Ranger in January, 2020, and that by March 25, 2020 approximately 65 acres has been cleared. The Applicant indicates that an additional 15 acres of tree clearing will be required, but this work has not been completed at this time. Exact locations of completed tree clearing are unknown, as are exact locations for all areas that are to be cleared. However, the BA states that Biltmore Farms will notify the Service prior to any tree clearing conducted after April 15, 2020. 2.3.3.2 Facility Construction – Stormwater Control The Applicant would put sediment and erosion control measures in place during facility construction. These controls are designed to accommodate 25-year storm events. Permanent stormwater measures will also be installed post-construction (Section 2.4). The Applicant’s approved sediment and erosion control plan are detailed in Appendix D, and include the following provisions: 12 • Each sediment storage device must be inspected after each storm event. • Maintenance and/or clean-out is required any time the device is at 50% capacity. • If approved sediment and erosion control measures prove insufficient, the Applicant must take additional steps to prevent sediment from leaving the construction site. The North Carolina Division of Energy, Mineral, and Land Management requested site-specific additional measures detailed in (Sections 2.4.4 and 2.4.5 and Appendix D). 2.3.3.2 Facility Construction – Construction Access Roads Access to the construction site would utilize Old River Road (existing gravel road), an unnamed unimproved road that crosses under the BRP, and an unimproved unnamed roadway that connects the site to I-26 (Appendix A, Figures 2 and 11). These roads may require improvements to accommodate construction equipment and materials. Roads may require gravel amendments, and tree clearing within 25 feet of either side of the roads. Vegetative clearing in these areas would not involve grubbing stumps or grading to widen roads. No culverts would be replaced at existing stream and wetland crossings. 2.3.3.3 Facility Construction – Demolition of Abandoned Buildings Three abandoned buildings would be demolished prior to facility construction. The Applicant indicates that the structures would be inspected 30 days before demolition begins for evidence of bat use. If bats are present within the structures, the Biltmore Farms will provide 30 days to accomplish bat removal prior to building demolition. 2.3.3.4 Facility Construction – Blasting Blasting may be required to develop the undisclosed industrial facility. Blasting activities would begin in August 2020 and continue as needed until March 2021(Appendix A, Figure 5). The Applicant indicates that 60 total blasts would be required during this time period. Noise levels from blasting can reach 126 decibels (NRC, 2012). Blast mats may be used to suppress noise and dust in areas where small quantities of rock or trench rock are blasted. Blast mats are unlikely to be used for mass blasting, which may be required in areas of high rock, such as the proposed parking lot. 2.3.3.5 Facility Construction – Night Work Temporary construction lighting would be used to facilitate night work to accomplish construction deadlines. Nighttime lighting used within 50 feet of the French Broad River between March 15 and November 15 would be aimed directly at the work area to avoid lighting the river and potentially adversely affecting the gray bat. The Applicant indicates that clearing, grubbing, and installation of base material for the manufacturing facility would not exceed three total nights during the bat maternity season (May 15 – August 15). Construction of the manufacturing facility may include additional night work during the bat maternity season to accomplish concrete pours, placement of panel walls, plumbing and piping, 13 and setting the roof structure. The Applicant is unable to estimate the amount of night work required for facility construction. Electrical and plumbing work would occur after the building shell is constructed and would not require exterior lights. The Applicant indicates that night work for all construction activities, not including facility construction, would not exceed 22 total nights during the bat maternity season (see section 2.4 regarding this and other proposed conservation measures). 2.3.4 Proposed Action – Bridge Design The proposed bridge over the French Broad River would be located approximately 1,000 linear feet downstream (north) from the existing BRP bridge. The bridge would be approximately 610 feet in length and constructed to have approximately 20 to 30 feet of clearance above normal water surface elevation (Appendix A, Figures 3 and 4). According to the information provided, the Applicant anticipates a three-span bridge (two bents in the river), with concrete deck, on continuous steel girders. The center span is anticipated to be approximately 240 feet in length, situated approximately at the center of the river. To address potential concerns for aesthetics and impacts to the view shed from the existing BRP bridge, guardrail design is being coordinated with the National Park Service. The proposed bridge would initially be striped to accommodate three lanes of traffic, but is designed to support future construction of up to five lanes of traffic and a pedestrian walkway. The BA indicates that the bridge and access road would be turned over to the NCDOT for upkeep beginning March, 2021. The NCDOT expressed their intent to add the proposed access road and bridge into the state system of maintenance following construction (Appendix E). Therefore, the proposed roadway and bridge are designed to meet minimum NCDOT standards. 2.3.4.1 Bridge Design – Permanent Lighting The permanent lighting design for the French Broad River bridge calls for two lights at the center of the bridge, and two additional lights (six lights total) at each of the bridge abutments (Appendix A, Figure 7). The bridge and roadway would use Type II LED light fixtures with a 1- 0-1 BUG rating which are designed to minimize light spill (See section 2.4 for more information about this and other proposed conservation measures). Additional permanent lighting would be constructed near the bridge intersection with NC-191 on the west side of the river (Appendix A, Figure 7). The BA indicates that permanent lighting for Project Ranger would comply with Buncombe County lighting standards, which are intended to minimize light pollution, light trespass and glare, and promote energy efficiency (Buncombe County, 2019). The Project would use warmer color temperature lighting (CCT < 3,000K), utilize LED light fixtures with lumen output equal to or less than Buncombe County requirements, and employ downward-facing fully shielded lighting. The mounting height of all outdoor area lighting would not exceed 25 feet above the lowest adjacent elevation. 14 2.3.4.2 Bridge Design – Storm Water Control The proposed bridge would have no direct discharge into the French Broad River. Stormwater runoff from the bridge would flow west to grated inlets installed just off the bridge and then would discharge into riprap dissipater pads at non-erosive velocities at least 50 linear feet from the French Broad River. A deck drain system may be installed to reduce stormwater spread on the bridge. The deck drain system would consist of PVC lines running along the outer faces of the bridge, conveying bridge runoff to the west bridge approach, then would discharge into riprap dissipater pads at least 30 linear feet from the French Broad River. Dispersed sheet flow would then infiltrate through relatively flat vegetated areas and/or vegetated swales that discharge into the French Broad River. (Appendix A, Figure 4) 2.3.4.3 Bridge Design – Vegetative Maintenance Landscape maintenance plans of the bridge and roadway areas would be developed in coordination with NCDOT prior to turning facility operations over to an undisclosed owner/operator. Elements of native plantings and avoidance of invasive species will be incorporated per Buncombe County ordinances. Disturbed areas associated with the bridge construction would be inspected and treated for invasive species annually for three years post- construction. 2.3.5 Proposed Action – Bridge Construction The BA indicates that investigative drilling for bridge construction would begin and be completed in April 2020. All other bridge construction activities would begin August, 2020 and would be completed by October 2021 (Appendix A, Figure 5). However, the Applicant indicated by letter that site preparation and tree clearing activities would begin in January, 2020 (Appendix B). The construction of the bridge would be composed of the following component activities: 2.3.5.1 Bridge Construction – Vegetative Clearing and Excavation Tree clearing for bridge construction would total approximately 3.0 acres. On the west side of the French Broad River, approximately 270 linear feet of riparian vegetative clearing (1.3 acres) would be required. Approximately 260 linear feet of riparian vegetative clearing (1.7 acres) would be required along the east side of the river. Tree clearing would extend to the river edge at the bridge construction site. Denuded riverbanks would be stabilized with riprap to minimize erosion potential. Areas adjacent to the French Broad River would be excavated (Appendix A, Figure 4) to comply with FEMA requirements to offset the reduction in flood storage capacity caused by the proposed river crossing. Excavation would occur within 0.6 acres total. Excavation would not extend to the water’s edge. Riprap would be installed beneath the bridge at bridge endwalls and along the shoreline (Appendix A, Figure 4). Vegetative clearing limits would extend 83 linear feet from both bridge faces on both river banks to accommodate the minimum clearance for roadway and bridge maintenance. 15 2.3.5.2 Bridge Construction – Investigative Drilling Investigative drilling for bridge footings within the French Broad River would require two 6-inch diameter borings for each bent. Therefore, a maximum of four investigative borings would occur in the riverbed. The total affected riverbed area would be less than two square-feet. All investigative drilling in the river would be conducted within the causeway footprint. A drill rig would be situated on the riverbank or barge surrounded by a containment boom to minimize turbidity. Drill cores would be contained within a steel casing. Once retrieved, drill cores would be removed and analyzed in a laboratory. In April 2020, investigative drilling in the French Broad River would take approximately two weeks to accomplish including set-up time (Appendix A, Figure 5). 2.3.5.3 Bridge Construction – Bridge Footing Installation Once investigative drilling is complete, 10 five-foot diameter concrete drilled shafts for piers would be drilled into the river bottom (i.e. five shafts at both bent locations, totaling approximately 200 square-feet of direct disturbance to the riverbed). Construction drilling would begin in September 2020, and take up to eight weeks to complete (Appendix A, Figure 5). The drilling process would begin by placing a 60-inch diameter, 0.5-inch thick, steel casing vertically into the shaft. The casing would be clean, smooth, un-corrugated, watertight steel of ample strength to withstand handling and installation stresses and pressures imposed by concrete, earth, backfill, and fluids. The drill rig would twist and drive the casing vertically into the riverbed until rock is encountered (approximately 1 to 5 feet below the riverbed). The top of the permanent steel casing would remain at or above the elevation of the temporary causeway (see Section 2.3.5.5 for a description of proposed construction activity). A watertight catch pan would be placed on the causeway adjacent to the shaft location that would be used to retain drill spoil. A 60-inch diameter auger contained within the steel casing would be driven vertically into the riverbed until it encounters rock and is no longer able to proceed. The auger would be used to remove sediment spoil from within the casing. Spoil would be placed within a watertight catch pan adjacent to the shaft location. A rock auger or rock hammer contained within the casing would then be used to continue excavation into the rock. The steel casing would be twisted and driven further into the riverbed as rock is excavated to maintain a watertight seal, which typically occurs when the bottom of the casing is approximately two-feet into rock. Rock would be drilled and the casing would be driven to approximately 11 to 15 feet into rock (approximately 15 to 20 feet below the streambed). As drilling proceeds to this ultimate depth, spoils would be removed from the casing and placed into an adjacent catch pan as described above. The catch pan would be transported across the temporary causeway to an upland disposal area at least 30 feet from the river edge where the spoils would be treated through an approved NC Department of Environmental Quality (NCDEQ) erosion control device. Once rock excavation is complete, remaining spoils and water within the shaft would be cleaned out using a flat bottom cleanout bucket and/or pumped through a hose to an upland disposal area at least 30 feet from the river edge where it would be treated through an approved NCDEQ erosion control device. Drilling of bridge footings would not require the use of slurry or drilling 16 fluids except for a small amount of water to cool machinery that would be contained within the watertight steel casing. Steel reinforcement would then be placed within the shaft and concrete would be pumped directly into the watertight permanent steel casing lining the shaft. Portions of this activity associated with concrete pouring may require night work (see Section 2.3.5.6 below for more detail about proposed nightwork for bridge construction). 2.3.5.4 Bridge Construction – Pile-Driving Pile-driving may be required at end bents to provide sufficient structural support. Pile-driving would begin September 2020, continue for two weeks, require no night work, and would be accomplished from land, not causeways. Noise levels from pile driving can reach 110 decibels (NRC, 2012). No blasting would occur at the bridge construction site. 2.3.5.5 Bridge Construction – Causeways Temporary rock causeways would be required to construct portions of the proposed bridge located in the French Broad River. Causeways would be placed in the river in August 2020, and remain for 12 months to accommodate the drilling of concrete piers (Section 2.3.5.3), constructing concrete caps at each bent, and setting the spans. Temporary causeways would be approximately 114 linear feet wide, and extend into the French Broad River 80 feet and 70 feet from the west and east banks, respectively, (0.34 acre total) (Appendix A, Figure 4). However, the centermost girder span (approximately 100-feet long), would require that both causeways be extended an additional 24 feet downstream and 40 feet into the river for three months to accommodate the positioning of cranes. This girder section would be installed last and would create an additional 0.33 acre of temporary impact to the French Broad River. Causeway materials would consist of class II riprap (maximum size of 24-inch) or larger. Causeways may require a cap or surface layer composed of class B riprap (maximum size of 12- inch) or larger. Causeways would be installed such that total streamflow blockage would not exceed 64% at any time. Causeway footprints would be the minimum needed to construct the bridge and side slopes would be maximized (1.5:1) to reduce their size. Solar-powered red safety lighting will be used on the causeways and the public will be notified prior to causeway placement to ensure boater safety. The Applicant considered the use of a temporary work bridge but deemed it not practical and more costly due to the shallow depth of rock below the riverbed, which would require drilling temporary concrete piers at eight temporary bent locations. 2.3.5.6 Bridge Construction – Night Work The Applicant indicates that night pours of concrete are required during hot weather to achieve a proper cure. Concrete pours for bridge construction are the primary work activities that may occur at night. Night pours may occur twice per week, each lasting 10 hours per night. Total 17 night work for concrete pours for bridge construction would not exceed 10 nights during the bat maternity season (May 15 – August 15). Night pours would be required for bridge deck construction and would require the most lighting of all construction activities associated with Project Ranger. Each night pour for bridge decking may take 10 hours, beginning at midnight. The Applicant indicates that this work would require no long-term consecutive nights of operation. The majority of lighting would be positioned at bridge deck level, with lights shining toward the bridge rather than toward the river. Two to four light plants on the bridge deck would be used to illuminate the work area. Small lights, similar to headlights would be used to illuminate the screed (concrete surface) as needed to ensure a proper cure. Headlights from pump trucks and delivery trucks on the deck surface and causeways would be used to illuminate work areas. Night pours may also be required for the construction of bridge footings, bent caps, end bents, and barrier rail walls. The use of lighting for each night pour would be less than six hours in duration and restricted to relatively small work areas. Lights would be set on the causeway, directed upward at the bridge member being poured. Lighting from headlights on pump trucks and concrete trucks located on the bridge deck and causeway would also be present during night pours. Solar-powered red safety lighting will be used on the causeways to ensure boater safety. 2.3.6 Proposed Action – Access Road Design and Construction The proposed access road to the facility would intersect Brevard Road (NC-191), bridge the French Broad River, then approach the facility parking lot from the south (Appendix A, Figures 2 and 3). The proposed access road will be cleared and graded to accommodate a four-lane road in the future. However, only two lanes would be paved initially (Appendix A, Figure 3). The Applicant indicates that additional lanes would be paved to accommodate future development needs onsite and any additional traffic. Design plans call for the grading of an area along the roadway to accommodate future construction of round-about (Appendix A, Figure 3). The BA states that grading for this round-about would be accomplished during the initial phase of development to avoid future disruption of Project Ranger operations, and that the roundabout would allow future traffic from the south to return to the proposed bridge without entering the Project Ranger facility. No plans (conceptual, draft, final, or otherwise) for onsite or offsite development associated with this bridge and roadway have been provided at this time. The BA indicates that the bridge and access road would be turned over to the NCDOT for upkeep beginning March, 2021. The NCDOT expressed their intent to add the proposed access road and bridge into the state system of maintenance following construction (Appendix E). Therefore, the proposed roadway and bridge are designed to meet minimum NCDOT standards. Based on the information provided, future development associated with the proposed project is reasonably certain to occur but it is unclear what exactly will necessitate the expansion of this roadway or when it would occur. 18 2.3.7 Proposed Action – Utilities Design and Construction According to the BA, several aspects of design and construction timing for requisite utilities remain unknown (but see Appendix A, Figures 3, 4, 5, and 6). However, based on the information provided, appurtenant utilities would be composed of the following component activities: 2.3.7.1 Utilities – Sewer A Metropolitan Sewerage District (MSD) sewer line runs parallel to the French Broad River along its eastern bank (Appendix A, Figures 3 and 6). The Applicant indicates that the proposed undisclosed development would not require an expansion of existing MSD collector lines. A 50- foot wide right-of-way (ROW) would extend approximately 800 linear feet from the existing sewer line to the northwest corner of the facility. Alternatively, the proposed sewer line and its ROW would extend along an existing logging road (Appendix A, Figure 6). The BA indicates that proposed tree clearing for either option is approximately the same. 2.3.7.2 Utilities – Water and Gas Proposed water and gas lines would tie into existing lines at the NC 191 interchange and would attach to the proposed bridge and run along the road alignment depicted in design plans (Appendix A Figures 3 and 4). Alternatively, the water supply and gas utility lines would be directionally bored under the French Broad River (minimum depth of six feet) at the bridge crossing location, then run along the road alignment depicted in design plans (Appendix A, Figures 3 and 4; Appendix C). The Applicant has prepared a frac-out contingency plan to contain spilled drilling fluid and minimize environmental impacts (Appendix C). Notably, the frac-out contingency plan calls for a vacuum truck to remain onsite to facilitate containment in case of an inadvertent spill. 2.3.7.3 Utilities – Electric Substation The undisclosed development would require an electric substation that will require approximately three acres of tree clearing. The location of the proposed substation is undetermined at this time, but would be located at least 400 linear feet from the French Broad River (Appendix A, Figure 3) 2.4 CONSERVATION MEASURES The Applicant has committed to the following measures to avoid, minimize, or offset potential project-mediated effects to MYGR and Appalachian elktoe. These conservation measures fall into two general categories: 1. Measures to avoid/minimize effects 2. Measures to compensate for, or partially offset anticipated effects 19 Some of these efforts directly benefit one species or the other, but many are beneficial to both species. 2.4.1 Conservation Measures – Minimization of Tree Clearing • Tree-clearing has begun for Project Ranger in order to remove trees in winter, reducing potential effects to bats. Biltmore Farms will notify the USFWS prior to any tree clearing after April 15. • In the area between the Blue Ridge Parkway and NC 191 (Brevard Road), no trees will be cleared beyond what will be necessary to construct the permanent project footprint, to establish associated sediment and erosion control devices, and to construct and maintain the bridge and approaches. • At the French Broad River, tree-clearing will be limited to what is needed for excavation and bridge construction. Tree-clearing in the vicinity of the bridge will total 3.0 acres. Tree-clearing is necessary along 83 ft. from each bridge face to allow for roadway/bridge safety and maintenance. On the west side of the river, clearing will run approximately 270 linear ft. (1.3 ac.). On the east side of the river, clearing will run approximately 260 linear ft. (1.7 ac.). • Excluding the bridge construction site, tree-clearing limits will extend no closer than 400 ft. from the French Broad River for the manufacturing facility. • There will be a 60+ ft buffer to the near (north) side of Bent Creek (measured to top of bank), 80+ ft buffer to near side of S15, and 10+ ft buffer to near side of S16. Riparian buffers will help to stabilize streambanks, shade streams (during the day and during nightwork), and prevent colonization by invasive plants. • Access to the construction site and the river will be along existing roads: NC 191 (Brevard Road) to the west, and two existing gravel roads on Biltmore property to the south (Appendix A, Figure 2) and will not require complete clearing of forested areas. Existing gravel roads may require limited clearing along road edges as part of the project, which would be limited to the clearing of trees and/or limbs and would not involve grubbing of stumps or grading to widen the roads. • Areas disturbed for bridge construction will be inspected/treated for invasive species annually for three years post-construction. 2.4.2 Conservation Measures – Construction Lighting • Biltmore Farms will limit all construction-related lighting to whatever is necessary to maintain safety in active work areas closest to the French Broad River. • Construction-related lighting will be indirect in nature and will not project into adjacent forested areas or over the water surface of the French Broad River or Bent Creek, whenever practicable. • Night work will be limited, and no nighttime lighting will be directed away from the work area within 50 ft. of the French Broad River, between March 15 and November 15. • Night pours at the bridge construction site will not exceed 10 nights during the MYGR maternity period. 20 • No more than 22 total nights of work may be necessary during the 2020 and 2021 maternity seasons, excluding night work that may need to occur at the manufacturing facility. • If total maternity season night work will exceed 22 nights, the Service will be notified (not counting night work occurring in the manufacturing facility interior, once constructed). 2.4.3 Conservation Measures – Bridge Design and Construction • The minimum number and size of piers necessary to support the bridge will be used in the French Broad River. • Stormwater runoff from the proposed bridge will flow west to grated inlets installed just off the bridge and then be discharged on riprap dissipater pads at non-erosive velocities at least 50 ft. away from the river. After leaving pads, stormwater will then be dispersed to sheet flow and infiltrate through relatively flat vegetated areas, where practical. Vegetated swales will carry the water downgrade to the river or other jurisdictional areas. • Biltmore Farms will conduct visual inspections of riprap dissipater pads once per week and after a rainfall event of one-half inch or greater until construction is complete. Inspections will occur monthly post-construction until the bridge is conveyed to NCDOT. • If a deck drain system is needed to reduce spread on the bridge, it will likely consist of PVC trunk lines running along the outer faces of the bridge and flowing to the west bridge approach, where it will be discharged on riprap dissipater pads at non-erosive velocities at least 30 ft. away from the river. All proposed stormwater runoff will be discharged as far away from the river and at the lowest velocities as practicable. • The primary phase causeways (estimated at no longer than 12 months) will not restrict more than 50% of the existing channel width of the French Broad River at a given time and are estimated to block up to 37% of the flow area. Short term duration causeways (estimated at 3 months) are estimated to block up to 64% of the flow area. • Causeway footprints will be the minimum necessary to construct the bridge, and side slopes will be maximized (approx. 1.5:1) to reduce their size and temporary impact to the river. • The contractor will use clean rock (free of debris and pollutants) for the construction of the causeways to minimize unnecessary sediment input into the river. • Causeway material will be removed to the extent practicable and either disposed of offsite or used in areas that require permanent stone protection after project completion. • Causeway placement will be staged. Causeway material will be added/removed as needed for each stage to minimize the causeway footprint over the length of the project. • To minimize disturbance to the riverbed, all readily detectible causeway material will be removed, to the extent practicable, while removing as little of the original riverbed as possible. • Construction fabric will not be used under the causeway material, as it tends to tear into pieces and float downstream during removal. • The causeway will consist of Class II riprap (maximum size of 24 in.) or larger, to minimize loss during storm events. If a cap or surface layer is used, it will consist of class B riprap (maximum size of 12 in.) or larger to minimize loss downstream. 21 • Concrete barriers (barrier rail) may be placed along the downstream edge of each causeway to limit the downstream movement of causeway material during high flow events, if needed. • Biltmore Farms will place solar-powered, steady-state red lights on the causeways to alert river users to their locations. This type of red lighting has been shown to cause a minimum amount of disturbance for Myotis bats (Downs 2003). Generators will not be used to provide power, so as to avoid additional noise that may disturb bats flying through the work zone. • The Service and NCWRC will be notified one week prior to removal of causeway material in the interest of maintaining/improving mussel habitat wherever possible. • When constructing drilled piers for the French Broad River bridge, permanent watertight steel casings will contain all disturbed material, fresh concrete and negligible water used to cool machinery, which will minimize effects to water quality. • Construction of bridge will be accomplished in a manner that prevents uncured concrete from coming into contact with water entering or flowing in the river. • A frac-out contingency plan for directional boring has been developed and is provided in (Appendix C). • When conducting the directional bore for utilities, drilling fluid will be pumped out of the shaft to an upland disposal area to the extent practicable and treated through a proper stilling basin or silt bag. 2.4.4 Conservation Measures – Erosion Control • When needed, combinations of erosion control measures (such as silt bags in conjunction with a stilling basin) will be used to ensure that the most protective measures are implemented. • Sedimentation and erosion control measures that will be in place during construction of the facility have been designed to accommodate 25-year storm events, instead of the typical design for a 10-year event. • If the approved sediment and erosion control measures prove insufficient to prevent sediment from leaving the construction site, the Applicant will take additional steps to prevent this from happening (Appendix D). • Each sediment storage device must be inspected after each storm event during construction. • Maintenance and/or clean-out is necessary any time the sediment and erosion control device reaches 50% capacity. • Sediment fencing will be installed a minimum of 10 ft. off the toe of the embankment to provide additional room for sediment storage and maintenance activities. • Slope drains (with rock inlet protection) will be added down the embankments of proposed temporary skimmer sediment basins at multiple locations, as specified by the Letter of Approval from the NC Division of Energy, Mineral and Land Resources (DEMLR). • To protect the existing wetland areas during grading operations, a double row of silt fence will be used at multiple locations, as specified by DEMLR (see Appendix D for details). 22 • Safety fencing will enclose undisturbed areas near several erosion control measures, as specified by DEMLR. • The contractor will notify Biltmore Farms and consult with the Geotechnical Engineer if ground water is encountered during the construction of sediment basin #1, as specified by DEMLR. • For stream protection, a double row of sedimentation fence will be used at several locations, as specified by DEMLR. • A Construction Project Inspector will monitor sediment and erosion control devices weekly, or after each rainfall event of one-half inch or greater for the life of the project. • Following high water events, any debris observed to be caught on temporary causeways will be removed. • Riverbanks will be inspected for signs of erosion once per week and after a rainfall event of one-half inch or greater during construction. If erosion is found, it will be stabilized in coordination with USFWS, NCWRC, and USACE. • Any equipment that is placed on the causeways will be removed any time throughout a work day when the water level rises or is expected to rise overnight. • Any machinery to be used on causeways will be clean and free of leaks. • Prior to construction, a limited qualitative evaluation will be made of the riverbanks immediately upstream and downstream of the proposed project to establish a baseline in the event future erosion is caused by this project. Riverbank inspections will occur once per week and after a rainfall event of one-half inch or greater until construction is complete. • Riprap will be used to stabilize areas of excavation beneath the bridge at bridge end walls and along the shoreline, (Appendix A, Figure 4). • Natural fiber coir matting will be used for erosion control. • Elements of native planting and the avoidance of invasive species will be incorporated per Buncombe County zoning ordinances. 2.4.5 Conservation Measures – Stormwater Control • The permanent post-construction stormwater measures will be designed to meet Buncombe County stormwater management standards, which require treatment of the 1- year, 24-hour storm event. • The rate of discharge will not exceed the pre-development rate of discharge for this same storm event. • Two stormwater ponds will be built with the initial phase of construction to accommodate future expansion. The outlets for the two proposed stormwater ponds will be directed away from wetlands and will be at least 500 ft. away from the river. Velocity control measures will be designed to limit scour and erosion at the outlets. • Stormwater outfalls and conveyances will be monitored for stability during construction. • Inspections will occur once per week and after a rainfall event of one-half inch or greater until construction is complete. Riprap or other measures will be used as necessary to prevent scouring and sedimentation. • Stormwater detention structures will be designed for the slow discharge of storm water and will not be installed within any stream or wetland. 23 2.4.6 Conservation Measures – Permanent Lighting • The project will use warmer lighting with correlated color temperature (CCT) of < 3,000K in perpetuity. • The project will use LED light fixtures with a lumen output equal to or less than Buncombe County requirements. • On the bridge and roadway, the project will use Type II LED light fixtures with a 1-0-1 BUG rating to minimize lighting spill in perpetuity. • The project will use downward-facing, full cut-off lights (fully shielded) in perpetuity, which will comply with Buncombe County lighting standards. • The mounting height of all outdoor area lighting shall not exceed 25 ft. above the lowest adjacent grade in perpetuity. • The proposed French Broad River bridge will have two lights at the center of the bridge. • Additional lights will be near the intersection with NC 191 on the west side of the river and near the limits of the flood plain on the east side of the river. The placement of the lights will provide safety on the bridge and approaches, while keeping the edges of the river as dark as possible for commuting and foraging bats. • Remaining lighting along the access road will likely be limited to intersections only. • Permanent lighting for Project Ranger will comply with Buncombe County lighting standards, which minimize light pollution, light trespass and glare, and promote energy efficiency. 2.4.7 Conservation Measures – Northern Long-eared Bat • For the duration of Project Ranger Construction, no alterations of a known hibernacula entrance or interior environment if it impairs an essential behavioral pattern, including sheltering Northern Long-eared Bats (January 1 through December 31); • For the duration of Project Ranger Construction, no tree removal within a 0.25-mile radius of a known hibernacula (January 1 through December 31); and • For the duration of Project Ranger Construction, no cutting or destroying a known, occupied maternity roost tree, or any other trees within a 150 ft. radius from the known, occupied maternity tree during the period from June 1 through and including July 31. • Tree-clearing has begun for Project Ranger in order to remove trees in winter, reducing potential effects to bats. By March 25, the manufacturing site had been cleared, which makes up 65 of the 80 acres to be cleared. Remaining areas consist of the access road, bridge and utility locations, and floodplain excavation area. • Biltmore Farms will notify the USFWS prior to any tree clearing after April 15. 2.4.8 Conservation Measures – Bog Turtle • Biltmore Farms will coordinate with USFWS and NCWRC to limit potential effects to Bog Turtles due to maintenance on the existing gravel roadway (River Road) during project construction. If any wetlands are within 25 ft. of the road, safety fencing will be installed around the wetland perimeter to avoid potential impacts while preparing for construction equipment access (Appendix A, Figure 8). 24 • Biltmore Farms will avoid impacting the wetland to be affected by bridge construction until May 15, 2020 thereby allowing NCWRC to survey the wetland for Bog Turtles in early May with the request that they provide email notification one week prior to arrival. Notification goes to Lee Thomason, lthomason@biltmorefarms.com. Contact Biltmore dispatch for gate access at 828-225-1581. On May 7, 2020, the NCWRC evaluated wetlands within proposed impact area. While these wetlands support salamander species, no turtles of any kind were detected at that time. • Biltmore Farms will provide access to wetlands to NCWRC and USFWS biologists for the purpose of long-term monitoring of bog turtle populations. This entails summertime inspections for a period of five years with the ability to renew for three years if mutually agreeable. Biltmore Farms requests a minimum of two weeks prior email notification, a single point of contact, and pre-registration of individuals to be on-site. Notification goes to Lee Thomason, lthomason@biltmorefarms.com. Contact Biltmore dispatch for gate access at 828-225-1581. 2.4.9 Conservation Measures – Gray Bat • Installation of bat roost panels at bridge once construction is complete. These will be approved by NCDOT in writing prior to installation. • Bat roost panel monitoring, to be coordinated with USFWS. Monitoring will be conducted annually between May 15 – August 15 by a trained bat biologist until the bridge is turned over to NCDOT. • Gray Bat monitoring for populations within the Action Area during construction to be coordinated with USFWS to aid in the recovery and conservation of this listed species. Biltmore Farms will pay an amount not to exceed $127,000 for Gray Bat monitoring while project construction is underway. Details on scope of work and payment will be finalized prior to construction. • Abandoned buildings/structures in the Action Area will be inspected for bat activity at least 30 days before demolition. Biltmore Farms is amenable to providing access to these structures, with the request that the designated bat biologist provide email notification one week prior to arrival. Should bats be present, Biltmore Farms will provide 30 days for bat removal before the buildings are demolished. • Biltmore Farms will provide access to the property to NCWRC, Indiana State University (or designated bat biologist), NCDOT, NV5 (NCDOT contractor) staff and USFWS biologists for the purpose of monitoring bat populations for the duration of Project Ranger and NCDOT I-26 construction projects. Since the site will be an active construction area for some of this duration, there will need to be additional safety restrictions on access times and personnel to the building site. With the understanding that more flexibility is needed with monitoring bats, Biltmore Farms is amenable to substitute conditions for pre-qualification meetings and email notifications 24 hours prior to site activity. Each agency will provide a single point of contact, and pre-registration of individuals to be onsite. Contractors should additionally provide a Certificate of Insurance, which lists Biltmore Farms, LLC as “additionally insured.” Notification goes to Lee Thomason III, lthomason@biltmorefarms.com. Contact Biltmore dispatch for gate access at 828-225-1581. 25 2.4.10 Conservation Measures – Appalachian Elktoe • Biltmore Farms will provide $15,000 in funding to the North Carolina Nongame Aquatic Projects Fund for the French Broad River Conservation Plan (FBRCP) proposed by USFWS, which will aid in the recovery and conservation of Appalachian Elktoe and other associate freshwater mussel fauna of the French Broad River. The funding will be held by the NCWRC. A multi-agency/organization group of mussel species experts, including USFWS, will determine how to expend the funds. 2.5 OTHER CONSULTATIONS WITHIN THE ACTION AREA No previous consultations pursuant to section 7 of the Act have been completed within the Action Area for Project Ranger. 3. STATUS OF THE SPECIES 3.1 GRAY BAT This section summarizes best available data about the biology and current condition of the gray bat (Myotis grisescens - gray bat) throughout its range that are relevant to formulating an opinion about the Action. The USFWS published its decision to list the gray bat as endangered on April 28, 1976. There is no designated critical habitat for this species. 3.1.1 Gray Bat Species Description and Life History The gray bat is one of the largest species in the genus Myotis in eastern North America, with a forearm length of 40 to 46 millimeters, a weight of 7 to 16 grams (usually 8 to 11 grams), and a wingspan of 27.4 to 30 centimeters (Barbour and Davis 1969). Gray bats can most readily be distinguished from other Myotis by their wooly, unicolored dorsal fur, which may seem paler on the bats’ bellies. The fur appears gray after the mid-summer molt, becoming chestnut brown or bright russet leading to the next molt (Gore 1992). Another diagnostic morphological character is the gray wing membrane which connects to the foot at the ankle rather than the base of the toes (Barbour and Davis 1969, Gore 1992). The nails on the feet are notched and the calcar is unkeeled (Harvey et al. 1981, Sealander 1979). The range of the gray bat is concentrated in the cave regions of Alabama, Arkansas, Kentucky, Missouri and Tennessee, with smaller populations found in adjacent states, including a growing population in a quarry in Clark County, Indiana (Harvey et al. 1981, Brack et al. 1984, Harvey 1992, Harvey 1994, Mitchell 1998). Gray bats are one of the few species of bats in North America inhabiting caves year-round. The species occupies cold caves or mines in winter and warmer caves during summer (Tuttle 1976a, Harvey et al. 1981, Harvey 1994, Martin 2007). In winter, gray bats hibernate in deep vertical caves that trap large volumes of cold air and the species typically forms large clusters with some aggregations numbering in the hundreds of thousands of individuals (Harvey 1994, Tuttle and Kennedy 2005). The species 26 chooses hibernation sites where there are often multiple entrances, good air flow (Martin 2007) and where temperatures are approximately 5°-9° C, though 1°-4° C appears to be preferred (Tuttle and Kennedy 2005). Tuttle (1979) noted that an estimated 95% of the range-wide population was confined to only nine hibernacula. There are some exceptions to this cave-specific roosting strategy. Many bat species use bridges as roost sites (Keeley and Tuttle 1999) and the gray bat is no exception. Bridges provide a warm refuge for individuals either foraging far from their primary daytime roosts or can serve as primary roosts during summer months. Gray bat bachelor and maternity colonies have been found in culverts in Arkansas (Harvey and McDaniel 1988, Timmerman and McDaniel 1992), Kentucky (Hays and Bingham 1964), and Kansas (Decher and Choate 1988). Culvert conditions can mimic those found in natural caves in terms of high levels of humidity and clear running water. Maternity colonies have also turned up in more unusual places, such as a barn in Missouri (Gunier and Elder 1971) and the gate room of a large dam in Tennessee (Lamb 2000). We are continually expanding our knowledge of where gray bats can roost, and bridge and culvert roosts are more common than previously thought. Gray bats show strong philopatry to both summering and wintering sites (Tuttle 1976a, Tuttle 1979, Tuttle and Kennedy 2005, Martin 2007). Because of their highly specific roost and habitat requirements, only about 5% of available caves are suitable for occupancy by gray bats (Tuttle 1979, Harvey 1994). At all seasons, males and yearling females seem less restricted to specific cave and roost types (Tuttle 1976b). Bachelor males segregate in separate aggregations within a colony home range that usually includes several caves that may extend up to 70 kilometers along a particular river valley (Tuttle and Kennedy 2005). Gray bat hibernacula are often comprised of individuals from large areas of summer range. Based on band recovery data, Hall and Wilson (1966) calculated that a gray bat hibernaculum in Edmonson, County Kentucky attracted individuals from an area encompassing 27,195 square kilometers in Kentucky, southern Illinois, and northern Tennessee (Hall and Wilson 1966). Gray bats are documented to regularly migrate from 17 to 437 kilometers between summer maternity sites and winter hibernacula (Tuttle 1976b, Hall and Wilson 1966), with some individuals moving as much as 689 to 775 kilometers (Tuttle 1976b, Tuttle and Kennedy 2005). Gray bats are reproductively mature at two years of age (Miller 1939, Tuttle 1976a) and mate between September and October. Copulation occurs upon arrival at hibernating caves, whereupon females immediately enter hibernation. Mating males may take a few weeks to replenish fat stores, but are typically in hibernation by early November (Tuttle 1976b, Tuttle and Stevenson 1978). Adult females store sperm throughout hibernation, a strategy known as delayed fertilization, and pregnancy begins following their spring emergence (Krulin and Sealander 1972). After a gestation period of 60 to 70 days (Saugey 1978), females give birth to one pup between late May and early June. Newborn young weigh approximately one-third of their mother’s weight and are volant within 21-33 days (Tuttle 1976b, Harvey 1994, Tuttle and Kennedy 2005). In summer, female gray bats form maternity colonies of a few hundred to many thousands of individuals. Nursery colonies typically form on domed ceilings of caves that are capable of 27 trapping the combined body heat from clustered individuals and where the temperature ranges between 14° and 25° C (Harvey 1992, Harvey 1994, Tuttle and Kennedy 2005 and Martin 2007). All other individuals not actively mating, both male and female, occupy caves on the outlying edge of the home range (Tuttle 1976b). Gray bats f eed exclusively on insects, with flies (Diptera), beetles (Coleoptera), caddisflies (Trichoptera), moths (Lepidoptera), wasps (Hymenoptera), stoneflies (Plecoptera), leafhoppers (Homoptera), and mayflies (Ephemeroptera) being the most important orders of insect prey (Rabinowitz and Turtle 1982, Clawson 1984, Brack 1985, Lacki et al. 1995, Best et al. 1997). Diet has been found to coincide most directly with the predominantly available prey species in the foraging area (Clawson 1984, Barclay and Bingham 1994), including both terrestrial and aquatic species (Clawson 1984). A study examining fecal remains conducted by Brack and LaVal (2006) indicate that gray bat diets fluctuate to a minor degree depending upon varying factors such as age, sex, and location. Gray bat summer foraging is strongly correlated with open water of rivers, streams, lakes or reservoirs, where insects are abundant (Tuttle 1976b, LaVal et al. 1977). Results of surveys conducted in Tennessee indicate that wetland depressions are also important foraging sites for gray bats (Lamb 2000). Although the species may travel up to 35 kilometers between prime feeding areas over lakes and rivers and occupied caves, (LaVal et al. 1977, Tuttle and Kennedy 2005, Moore et al. 2017), most maternity colonies are usually located between 1-4 kilometers from foraging locations (Tuttle 1976b). Newly volant gray bats travel 0.0 – 6.6 kilometers between roost caves and foraging areas (Tuttle 1976a, Tuttle 1976b). At foraging sites, Tuttle (1976b) estimated that gray bats forage within roughly three meters of the water’s surface. Abbreviated instances of bad weather in early spring and late fall are generally the onl y times gray bats deviate from primarily feeding along local bodies of water, and then they are found foraging in forest canopies (LaVal et al. 1977, Stevenson and Tuttle 1981). Gray bats are known to establish foraging territories as insect numbers drop after dusk. Territories are controlled by reproductive females, which annually return to preferred territories (Brady et al. 1982, Goebel 1996). Gray bats tend to have large home ranges. Thomas and Best (2000) reported non-reproductive gray bats (males and females) from one northern Alabama cave foraged over areas of approximately 97 square kilometers. Moore et al. (2017) found reproductive female gray bats in Arkansas had a larger home range than previously thought, with an average of 159 square kilometers, and they depend on water for foraging and traveling. The home range for reproductive females may change depending on reproductive status, but could also change based on colony size, insect abundance, habitat continuity, land use, or a combination of these factors (Moore et al. 2017). During times of limited food resources, males and pre-reproductive females may be excluded from foraging territories (Stevenson and Tuttle 1981). Forested areas along the banks of streams and lakes serve as corridors for travel and as protective feeding cover for newly volant young (Tuttle 1979, Brady et al. 1982, Moore et al. 2017). Whenever possible, gray bats of all ages fly in the protection of forest canopy between roosts and feeding areas (USFWS 1982). In addition, young often feed and take shelter in forest areas near the entrance to cave roosts (Tuttle 1979). Individuals may also fly overland from relatively land- locked roost sites to reach the main river channel or tributary systems that lead to open-water 28 foraging sites (Thomas 1994, Best and Hudson 1996). Gray bats do not feed in areas along rivers or reservoirs where the forest has been cleared (LaVal et al. 1977). Young, non-volant gray bats experience healthy growth rates because their energy expenditure for thermoregulation is reduced by the roosting colony (Herreid 1963, 1967). In undisturbed colonies, young may take flight within 20 to 25 days after birth. However, young may not become volant for 30 to 35 days if disturbed (Tuttle 1975). Hunting is primarily learned by young on their own after learning to fly (Stevenson and Tuttle 1981), though lactating females will continue to nurse their offspring for a short time after they become volant. Survival and growth of volant young is inversely proportional to the distance travelled for shelter and food (Tuttle 1976a). Roosts are cool during this period of lactation and females are often required to feed continuously to sustain the high body temperatures required to nurse (Tuttle and Stevenson 1977). Distance traveled to feeding areas may also be correlated with adult mortality (Martin 2007). Gray bats have been recorded as living up to 17 years (Harvey 1992, Tuttle and Kennedy 2005), with a mean annual survival rate of 70 percent in males and 73 percent in females (Gunier and Elder 1971). While survivorship among juveniles is relatively high (Saugey 1978), only 50 percent of gray bats reach maturity (USFWS 1980). Mortality rates are higher during the spring migration when fat stores have been expended and food resources can be scarce (Tuttle and Stevenson 1977). 3.1.2 Gray Bat Status and Distribution The gray bat largely occupies a limited geographic range in karst areas of the southeastern United States. They are mainly found in Alabama, northern Arkansas, Kentucky, Missouri, and Tennessee. A few can be found in northwestern Florida, western Georgia, southeastern Kansas, southern Indiana, southern and southwestern Illinois, northeastern Oklahoma, northeastern Mississippi, western Virginia, and western North Carolina. In the late 1970s, Tuttle (1979) estimated the total population to be approximately 2.25 million. The population was estimated at only 1.6 million in the early 1980s (Brady et al. 1982) and fell to 1.5 million within the next 10 years (Harvey 1992). By 2001, the population increased to 2.3 million (Mitchell and Martin 2002), and again to 2.5 million in 2003 (Harvey et al. 2004). This is a net increase in population size of approximately 10 percent between the 1970’s and 2003, and an increase of 40 percent from the smallest population estimate. The status of hibernating populations of gray bats was further reviewed in 2006 (Harvey and Currie 2007). At that time, the population was estimated at 3,377,100 – an estimated increase of 104 percent from 1982 (Harvey and Currie 2007). As defined in the Gray Bat Recovery Plan, Priority 1 (P1), hibernacula include caves occupied now or in the past by more than 50,000 gray bats in northern Alabama and Tennessee, and 25,000 elsewhere (USFWS 1982). Most of the 17 current P1 caves were designated in the recovery plan, but several additional caves have been identified as having significant winter populations more recently. From 2013 -2015 many of the 17 P1 hibernacula were surveyed, however not all caves were surveyed in the same winter. In 2017, winter surveys of all P1s were conducted, including the largest hibernaculum, Fern Cave, in Alabama. This coordinated, 29 rangewide effort provided the best opportunity in decades to estimate the gray bat population, now estimated at approximately 4,358,263. 3.1.3 Threats to Gray Bats The primary cause of gray bat population decline is human disturbance of their natural habitat (Barbour and Davis 1969, Mohr 1972, Harvey 1975, Tuttle 1979, USFWS 1982, USFWS 2009b), with wintering sites and maternity roosts especially susceptible to disruption. Commercialization of caves, spelunking, and looting for archaeological artifacts are activities that most commonly result in disturbance to roosting bats (USFWS 1982, USFWS 2009b). Disturbance in the hibernacula occurs when a human enters the cave and bats wake from hibernation, using vital energy stores that cannot be recovered before emerging in the spring (Tuttle 1976b). Approximately 20 to 30 days of stored energy is depleted with each arousal (Daan 1973). Losing these fat stores can cause bats to leave the roost prematurely in search of food during unsuitable circumstances, which may result in high mortality rates. During the first hour of arousal, individuals may lose up to 0.48 g of body weight; a significant amount when contrasted with the typical hibernation losses of 0.01 g per day (Brady et al. 1982). When this human interference occurs in maternity caves it is typically most devastating in late spring and early summer (May to July), as non-volant offspring are in the roost. Thousands of bats may die from a single disruption (USFWS 1982). In addition, Stevenson and Tuttle (1981) found that banded gray bats tended to avoid roosts where they had been handled by researchers. Humans are also impacting the environment in other ways that can negatively impact bats. Deforestation close to cave entrances, at foraging sites, and along commuting routes is likely to have negative effects due to the removal of prey abundance and reduced cover from natural predators (Tuttle 1979). Recently-volant young are especially susceptible to the effects of deforestation, as they require the protection of forest cover while becoming proficient fliers. Insecticide use historically had a detrimental impact on gray bat populations (Clark et al. 1978, Clark et al. 1988), though many of the toxic substances are now banned from the market. The longevity, high metabolic rate, and insectivorous diet of bats increases their likelihood of exposure to bioaccumulating chemicals in the environment. While modern pesticides (e.g., organophosphates, neonicotinoids, pyrethroids, carbonates) aren’t expected to bioaccumulate in tissues, they are still a concern, are highly toxic, and may kill bats from direct exposure (Shapiro and Hohmann 2005). The presence of other contaminants of concern that can bioaccumulate (e.g., pharmaceuticals, flame retardants) has been documented in bats (Secord et al. 2015), though additional research is needed to understand impacts. Additionally, pesticides and other pollutants could indirectly impact bats by reducing insect populations. Siltation and nutrient loading of waterways where bats forage and drink may negatively affect the species. As previously stated, a large portion of the gray bat diet is comprised of adult aquatic insects such as mayflies, stoneflies, and caddisflies. These groups of aquatic insects are especially susceptible to degraded water quality. Any substantial declines in the populations of these insects may have a detrimental effect on gray bat populations as well (USFWS 1982). Tuttle (1979) presented a correlation between a decline in gray bat numbers and an increase in sedimentation in several Alabama and Tennessee waterways. 30 Tied to increased waterway siltation is impoundment of streams and rivers to create reservoirs. While it was originally suspected that this practice would increase suitable foraging habitat for gray bats, it was ultimately found that the opposite is true (USFWS 1982). Disturbance to roosting bats using caves adjacent to these impoundments has also been observed. Noise from passing watercraft increased, as did access to cave roosts previously far from population centers and roads (USFWS 1982). Gray bat populations could also be impacted by temperature and precipitation changes due to climate change. Climate change will likely affect the distribution of suitable hibernacula for bats (Humphries et al. 2002). Since gray bats are a cave-obligate species, requiring highly specific hibernacula and maternity caves, they are acutely at risk from fluctuating climate conditions. As temperatures rise, conditions within gray bat hibernacula and maternity caves could change, making them less suitable. In addition, the increase in overall temperatures may lead to earlier arousal from hibernation, resulting in higher energy expenditure and potentially premature parturition (Sherwin et al. 2013). Changes in precipitation is also of concern. Under drought conditions, bats have to travel further distances for food and more rainfall could inhibit insect flight and decrease prey availability. These changes could have particularly adverse effects on nursing females, as the energy costs associated with traveling longer distances for food and water result in longer lactation times, slowing overall juvenile development (Tuttle 1976b, Adams 2010). Furthermore, increased frequency of severe storms could lead to flooding of important roost sites. Another potential threat to gray bat populations is the fungal disease white-nose syndrome (WNS). The disease is caused by the fungus Pseudogymnoascus destructans, which grows on the wings, ears, and muzzle of hibernating bats (Cryan et al. 2013). Since its discovery in New York in 2006, WNS has had an overwhelmingly negative effect on North American hibernating bats, eradicating millions of individuals. Mortality rates in afflicted bats often exceed 90 percent (Thogmartin et al. 2013). Bats that have been infected with WNS display erratic changes in behavior including day-time flying and increased frequency of arousal during hibernation (Cryan et al. 2013). In 2012, USFWS confirmed the first instance of WNS in gray bats (USFWS 2012b). The full impact of WNS on overall gray bat populations is still being determined. It seems plausible that WNS would pose a serious threat to a species like the gray bat, where individuals overwinter in few high-density hibernacula, should it infect those colonies. However, some studies have found that P. destructans may not spread through gray bat colonies as quickly as once expected, nor be as substantial a threat to the species as initially suspected (Flock 2014, USFWS 2012). As of spring 2017, the species has yet to experience any WNS-related declines and their populations appear to have remained stable within Tennessee (Bernard et al. 2017) and Virginia (Powers et al. 2016). Several behavioral traits, such as preferred microclimates within hibernacula and sustained activity and foraging throughout winter (Bernard and McCracken 2017) may enable this species to prevent or minimize the colonization of P. destructans during torpor. Studies have consistently shown that bat species richness decreases with the presence of artificial lighting in foraging and roosting areas, with Myotis species particularly vulnerable (Spoelstra et al. 2017; Stone et al. 2012; Downs 2003; Linley 2017). 31 Lighting may exacerbate the barrier effect of roads, since those species reluctant to cross open spaces are also those most likely to avoid light. There are no data specific to MYGR for the use or avoidance of lighted areas that may occur along roadways. Research by Rydell and Baagøe (1996) indicates that bats in the genera Eptesicus (big brown bats, Eptesicus fuscus) and Lasiurus (red and hoary bats, Lasiurus borealis and L. cinereus, respectively) are the species typically noted foraging around artificial lights. In contrast, they noted that bats in the genus Myotis seem to avoid open spaces, preferring to feed in woodlands or low over water. Additional studies (e.g. Rydell 1992; Blake et al. 1994; Stone et al. 2009, 2012) have shown that road lighting deters many bat species, notably slow-flying, woodland-adapted species such as members of the genera Rhinolophus, Myotis and Plecotus, from approaching the road. Therefore, artificial lighting may cause avoidance behavior in MYGR. Type and color of artificial lighting has been shown to impact bat species differently. Studies have shown a significant decrease in Myotis foraging activity levels under white and green light (4000K and higher) (Spoelstra et al. 2017). Red light (approximately 3000K) has been shown to cause a minimum amount of disturbance activity levels of Myotis bats when compared to dark foraging areas (Downs 2003). Bats’ eyes have evolved to function in low light and are less effective in brightly lit areas, and some groups of bats, including three species of Myotis occurring in North America, can detect ultra-violet (UV) light (Gorresen et al. 2015). Artificial lighting of any kind can cause a delay in emergence and increase the overall duration of emergence (Stone et al. 2009; Rydell et al. 2017). This in turn decreases available foraging time, juvenile growth rates, and the overall colony health (Stone et al. 2015). Studies have shown that bats using roosts lit by artificial light exhibit delayed emergence (Stone et al. 2009; Rydell et al. 2017); while one study has noted an overall drop in bat activity at artificially lit sites (Linley 2017). The presence of artificial lighting may force light-shy bats to use suboptimal flight routes or fly further to reach foraging sites and require them to expend more energy in the process (Stone et al. 2009, Stone et al. 2012). Artificial roost sites lit omnidirectionally, leaving no dark corridor to and from the roost, show high colony loss (Rydell, et al. 2017). Additionally, Myotis sp. have shown an increased avoidance of drinking areas lit by LED lighting (Russo et al. 2017). But both High Pressure Sodium (HPS) and LED light disturbance caused spatial avoidance of preferred commuting routes by R. hipposideros and Myotis spp. (Stone et al. 2009). LED lights produce a small amount of light in the UV range, when compared to other light sources like fluorescent, HPS, and metal halide (MH) (Lewanzik and Voight 2017, Wakefield et al. 2016, Wakefield et al. 2018). Insect activity has been shown to increase with the presence of UV light (Wakefield et al. 2016; Lewanzik and Voight 2017). More specifically, Wakefield et al. (2018) found greater numbers of insects were attracted to MH streetlights and a greater diversity of insects were attracted to white LEDs compared with long-wavelength-dominated HPS lights. While UV-producing lights may attract a larger number or greater diversity of insects, Lewanzik and Voight (2017) found that the number of Myotis calls increased after MH streetlights were backfitted with LED lights. This may be because of their sensitivity to UV light (Gorresen et al. 2015), causing them to avoid those areas. 32 3.2 APPALACHIAN ELKTOE This section summarizes best available data about the biology and current condition of Appalachian elktoe (Alasmidonta raveneliana) throughout its range that are relevant to formulating an opinion about the Action. The USFWS published its decision to list Appalachian elktoe as endangered on September 3, 1993. There is no designated critical habitat for this species in the Action Area. 3.2.1 Appalachian Elktoe Species Description and Life History Lea (1834) described the Appalachian elktoe from the French Broad River system in North Carolina. Its shell is thin but not fragile, oblong, and somewhat kidney-shaped, with a sharply rounded anterior margin and a broadly rounded posterior margin. Parmalee and Bogan (1998) cite a maximum length of 8 cm. However, individuals from the Little River (French Broad River basin) in Transylvania County and West Fork Pigeon River (French Broad River Basin) in Haywood County measured more than 9.9 cm in length (USFWS 2009b). The periostracum (outer shell) of the Appalachian elktoe varies in color from dark brown to yellowish-brown in color. Rays may be prominent in some individuals, usually on the posterior slope, and nearly obscure in other specimens. The nacre (inside shell surface) is a shiny bluish white, changing to salmon color in the beak cavity portion of the shell. A detailed description of the shell characteristics is contained in Clarke (1981). Ortmann (1921) provides descriptions of the soft anatomy. The reproductive cycle of the Appalachian elktoe is similar to that of other native freshwater mussels. Males release sperm into the water column, which is then taken in by the female through their siphons during feeding and respiration. The females retain the fertilized eggs in their gills until the larvae (glochidia) fully develop. The mussel glochidia are released into the water, and within a few days they must attach to the appropriate species of fish, which they parasitize for a short time while they develop into juvenile mussels. Juveniles then detach from their fish host and sink to the stream bottom where they may continue to develop, provided that suitable substrate and water conditions are present (USFWS 2002). The Appalachian elktoe is a bradytictic (long-term) brooder, with the females retaining glochidia in their gills from late August to mid-June (USFWS 2009b). Glochidia are released in mid-June, attaching to either the gills or fins of a suitable fish host species. Transformation time for Appalachian elktoe occurs within 18 to 22 days where mean temperatures are 18°C. Appalachian elktoe mussels use a variety of common fish hosts but appear to specialize on darters and sculpins, which are common in the Action Area. 3.2.2 Appalachian Elktoe Status and Distribution The Appalachian elktoe is known only from the mountain streams of western North Carolina and eastern Tennessee. It is found in gravelly substrates often mixed with cobble and boulders, in cracks of bedrock, and in relatively silt-free, coarse sandy substrates (USFWS 1996). Although the complete historic range of the Appalachian elktoe is unknown, available information suggests that the species once lived in the majority of the rivers and larger creeks of the upper Tennessee River system in North Carolina, with the possible exception of the 33 Hiwassee and Watauga River systems. In Tennessee, the species is known only from its present range in the main stem of the Nolichucky River. At the time of listing, two known populations of the Appalachian elktoe existed: the Nolichucky River, including its tributaries (the Cane River and the North Toe River); and the Little Tennessee River and its tributaries. The record in the Cane River was represented by one specimen found just above its confluence with the North Toe River (USFWS 1996). Since listing, the Appalachian elktoe has been found in additional areas. These occurrences include extensions of the known ranges in the Nolichucky River (North Toe River, South Toe River, and Cane River) and the Little Tennessee River (Tuckasegee River and Cheoah River) as well as a rediscovery in the French Broad River basin (Pigeon River, Little River, Mills River, and the main stem of the French Broad River). Many of these newly discovered populations are relatively small in numbers and range. The Appalachian elktoe has experienced declines in two populations across its range. A sudden die-off in the Little Tennessee River, (once considered the largest and most secure population of this animal), occurred from 2005 – 2015. During that time, periodic monitoring efforts failed to find any live individuals. Surveys during 2016 also failed to produce any observations of Appalachian elktoe, but surveys in 2017, 2018 and 2019 produced very low numbers, indicating a remnant population, but the population is limited and only a tiny fraction of its previous size. Appalachian elktoe also have declined in the lower portion of the Nolichucky River. Appalachian elktoe were once common in all three tributaries of the Nolichucky River: North Toe, South Toe and Cane River. In 2008, a fish kill linked to a waste water plant failure resulted in the death of most of the Appalachian elktoe in the Cane River. Beginning in 2013, the Appalachian elktoe population in the lower South Toe River declined steeply. This decline coincided with a major highway construction project and only occurred downstream of receiving streams in the project footprint. Appalachian elktoe are still present in the South Toe River, but at reduced densities. Appalachian elktoe are still present in the North Toe River, but at low densities. It appears that the North Toe population is limited by urban runoff and mining effects to the river. The other populations of Appalachian elktoe appear to be stable (Tuckasegee, Cheoah, and Pigeon Rivers) or expanding (French Broad River). A remnant population known in the Cheoah River since the early 2000's is presently being augmented by the NCWRC with hatchery-propagated individuals sourced from the Tuckasegee River. This effort appears to be successful in bringing this population back to a viable state. Prior to 2004, the French Broad River population appeared to be confined to two tributary streams (Little River, Mills River), but over the last few years the known range of Appalachian elktoe in the main stem of the French Broad River has expanded and it now appears to be well established, albeit at low density, over a broad area. 3.2.3 Threats to Appalachian Elktoe The decline of the Appalachian elktoe throughout its historic range has been attributed to a variety of factors, including sedimentation, point and nonpoint-source pollution, and habitat modification (impoundments, channelization etc.). The low numbers of individuals and the restricted range of most of the surviving populations make them extremely vulnerable to extirpation from a single catastrophic event or activity. Catastrophic events may consist of natural events, such as flooding or drought, as well as human influenced events, such as toxic spills associated with highways or railroads. 34 Natural flooding events combined with alteration of watersheds can lead to large fluctuations in abundance observed in Appalachian elktoe populations. Portions of the French Broad River basin and most of western North Carolina experienced catastrophic flooding in late summer 2004 as a result of Tropical Storms Francis, Ivan, and Jeanne. Numerous dead mussels, including the Appalachian elktoe, were observed in over-wash areas along the Little Tennessee River after the flood events. Additionally, surveys conducted in the Little Tennessee River after the flooding yielded noticeably lower catch per unit effort of live mussels, including the Appalachian elktoe, compared to past survey efforts in this section of the river (USFWS 2009). Siltation resulting from improper erosion control of various types of land use, including agriculture, forestry, road construction, and development, has been recognized as a major contributing factor to the degradation of mussel populations (USFWS 1996). Siltation has been documented to be extremely detrimental to mussel populations by degrading substrate and water quality, increasing potential exposure to other pollutants, and direct smothering of mussels (Ellis 1936, Marking and Bills 1979). Sediment accumulations of less than an inch have been shown to cause high mortality in most mussel species (Ellis 1936). The abrasive action of sediment on mussel shells has been shown to cause erosion of the outer shell, which allows acids to reach and corrode underlying layers (Harman 1974). Sewage treatment effluent has been documented to significantly affect the diversity and abundance of mussel fauna (Goudreau et al. 1988). Goudreau et al. (1988) found that recovery of mussel populations might not occur for up to 2 RM (3.22 km) below points of chlorinated sewage effluent. Most of the water bodies where Appalachian elktoe still exist have relatively few point source discharges within the watershed and are rated as having "good" to "excellent" water quality (NCDWR 2012, USFWS 1996). The introduction of exotic species, such as the Asian clam (Corbicula fluminea) and zebra mussel (Dreissena polymorpha), has also been shown to pose significant threats to native freshwater mussels. The Asian clam is now established in most of the major river systems in the United States (Fuller and Powell 1973). At the time the Appalachian elktoe was listed, the Asian clam was not known from the stretch of the Little Tennessee River that it occupies; however, it has been observed in the Little Tennessee River in recent years and, as mentioned earlier, may be a contributing factor to the decline of that population. Concern has been raised over competitive interactions for space, food, and oxygen between this species and native mussels, possibly at the juvenile stages (Neves and Widlak 1987). When the Appalachian elktoe was listed, it was speculated that, due to its restricted distribution, it "may not be able to withstand vigorous competition" (USFWS 1996). Another exotic species that has the potential to adversely impact aquatic species, including Appalachian elktoe, is the Japanese knotweed (Fallopia japonica). The plant is considered to be an invasive species that can reproduce from its seed or from its long, stout rhizomes. It can tolerate a variety of conditions, such as full shade, high temperatures, high salinity, and drought. It can be spread by wind, water, and soil movement to an area where it quickly forms dense thickets that exclude native vegetation and greatly alter the natural ecosystem. This species has become established in riparian habitats throughout western North Carolina. The species has a very shallow root system; because of this shallow root system and its preclusion of other 35 vegetation, areas where this species has been established may be susceptible to erosion during flood events. 4. ENVIRONMENTAL BASELINE Environmental baseline refers to the condition of the listed species or its designated critical habitat in the action area, in the absence of project-mediated consequences to the listed species or designated critical habitat. The environmental baseline includes the past and present impacts of all Federal, State, or private actions and other human activities in the action area, the anticipated impacts of all proposed Federal projects in the action area that have already undergone formal or early section 7 consultation, and the impact of State or private actions which are contemporaneous with the consultation in process. The consequences to listed species or designated critical habitat from ongoing agency activities or existing agency facilities that are not within the agency’s discretion to modify are part of the environmental baseline. 4.1 ENVIRONMENTAL BASELINE - GRAY BAT 4.1.1 Gray Bat Status and Distribution in the Action Area The best available information concerning the status of MYGR in the Action Area have been collected in association with proposed NCDOT developments in the project vicinity (see Section 2.4). Indiana State University (ISU) is conducting multi-year research of MYGR in the French Broad River Basin sponsored by the NCDOT in association with these transportation projects. The North Carolina Wildlife Resources Commission (NCWRC) conducts regular and supplemental monitoring for this and other bats species in the Project vicinity. Emergence counts conducted by ISU at known roosts in western North Carolina in 2018 and 2019 suggest that there are at least 1900-2300 MYGR in the French Broad River Basin. At this time, no MYGR hibernacula are known to occur in North Carolina, but a known primary roost is located within the Action Area for Project Ranger. Gray bats are present in the Asheville area from mid-March to mid-November (i.e. the MYGR active season). Monitoring efforts show that MYGR activity peaks during the last two weeks of July as pups become volant. Bat acoustic monitoring data collected for NCDOT-sponsored developments recorded MYGR calls at the bridges upstream and downstream from Project Ranger (NCDOT 2019). Moreover, in 2016, 2017, and 2018, the NCWRC and ISU captured and transmittered MYGR from known roosts within and adjacent to the project Action Area for radio telemetry tracking (BA Fig 9 of Appendix A). Tracking data show that MYGR move between roosts located north and south of Asheville, presumably flying through the Project Ranger Action Area (NCWRC 2017, Joey Weber pers. comm.). Bats appear to primarily forage over water, (i.e. the French Broad River and its tributaries), but animals were also detected in upland areas not associated with water (Weber et al. 2018). Acoustic monitoring data also suggest that MYGR activity is higher along the French Broad River than along its tributary creeks (NCDOT 2019). Gray bats that were captured at the roost within the Project Ranger Action Area typically returned to the roost each night, but did not consistently return to the same forage areas (NCDOT 2019a). Animals tracked from this roost were detected foraging north of Long Shoals Road, Hominy Creek, Bent Creek, 36 Long Valley Lake (on Biltmore Estate property), and various locations along the French Broad River (NCWRC 2017). Three abandoned buildings within the Project Action Area were inspected in March 2019, but no evidence of bats was detected at that time (Appendix F). 4.1.2 Factors Affecting Gray Bat Environment in the Action Area The main factor that could negatively impact gray bats in the Action Area is increasing urbanization. Development directly adjacent to the FBR has fragmented gray bat habitat by removing vegetation, increasing noise disturbances, and creating more artificially lighted areas that the bats must avoid as they commute from roost areas to forage areas. However, other factors in the Action Area could have a positive impact on the species. Improvements in water quality in the FBR have likely increased the prey base and improved the overall ability of bats to feed over the river. See Appendix G for baseline watershed conditions. 4.2 ENVIRONMENTAL BASELINE – APPALACHIAN ELKTOE 4.2.1 Appalachian Elktoe Status and Distribution in the Action Area Since 2004, the known range of Appalachian elktoe in the main stem of the French Broad River has expanded and now appears to be established at low density over a broad area (USFWS 2017). Prior to 2017, Element Occurrence (21150) of this species within the French Broad River was considered historic (first observed in 1840) and only extended up to the I-40 crossing. In 2017, records were found that extended the previously known range of this species 32 river miles upstream. Appalachian elktoe were detected in the Action Area within the French Broad River during surveys conducted October 4, 2019 (Appendix H). This survey was conducted from 400 meters downstream from the proposed bridge crossing to 100 meters upstream from the proposed bridge. Within that survey area, four surveyors targeted the highest quality habitat (based on best professional judgment). Surveyors conducted two passes of the survey reach, followed by a concentrated effort within the proposed bridge footprint. The survey effort detected one live Appalachian elktoe in 20.80 person-hours (catch per unit effort is 0.05/hr). 4.2.2 Factors Affecting Appalachian Elktoe Environment in the Action Area French Broad River water quality in the Action Area historically suffered from industrial and agricultural pollution. Beginning in the 1970’s, efforts were begun to reduce pollution and sediment entering the River. While the FBR is much cleaner today than in the past century, there are still threats from ongoing development. Portions of the FBR and several of the larger tributaries are on the 303d list of impaired waters. See Appendix G for baseline watershed conditions. 37 5. EFFECTS OF THE ACTION 5.1 EFFECTS OF THE ACTION – GRAY BAT Under section 7(a)(2) of the Act and the recent update to the regulations, effective October 28, 2019, “effects of the action” are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action. A consequence is caused by the proposed action if it would not occur but for the proposed action and it is reasonably certain to occur. Effects of the action may occur later in time and may include consequences occurring outside the immediate area involved in the action. The federal agency is responsible for analyzing these effects. The effects of the proposed action are added to the environmental baseline to determine the future baseline, which serves as the basis for the determination in this Opinion. Should the effects of the federal action result in a situation that would jeopardize the continued existence of the species, we may propose reasonable and prudent alternatives that the federal agency can take to avoid a violation of section 7(a)(2). 5.1.1 Factors to Be Considered – Proximity of the Action Based on acoustic and telemetry surveys within the Action Area, the gray bat occurs throughout the Action Area from mid-March through mid-November. One MYGR roost occurs within the Action Area. Multiple roosts have also been identified in the vicinity of Project Ranger. Radio-tracking data show that MYGR from offsite roosts also travel through, and likely forage in the Action Area. NCWRC telemetry studies in 2016 and 2017 (NCWRC 2017) and ISU telemetry work in 2018 (Weber et al. 2018) reveal that MYGR originating from the roost within the Action Area are using the French Broad River for commuting and foraging, although some individuals abandoned the river, choosing to fly over land or along large tributaries to the French Broad River such as Hominy Creek and Bent Creek. A smaller number of individuals also foraged in locations that were more unusual for the species, such as heavily wooded areas along the Blue Ridge Parkway, and partially wooded areas like the Riverside Cemetery, with no associated water sources. Acoustic and telemetry studies suggest that MYGR are present throughout the Action Area. They primarily use large waterways (the French Broad River) but are also present on smaller tributaries. Any work conducted over waterways when bats are present will impact the population. Although measures to avoid and minimize impacts to gray bats are included in the project plans, implementation of the project will result in unavoidable impacts to habitat and individual bats. 5.1.2 Factors to Be Considered – Nature of the Effect Disturbances from construction activities will temporarily impact foraging habitat and roosting MYGR within the Action Area. Once construction is complete, new permanent lighting, increased traffic, and project operations associated with Project Ranger will continue to impact commuting and foraging habitat. 38 • Temporary construction disturbances that occur during the MYGR active season may cause roosting bats to vacate the primary roost within the Action Area. MYGR may leave this roost during daylight hours to find alternate roosts, or attempt to forage after being woken from torpor when sufficient food is not available, which could reduce fitness or result in mortality. • Lighting and noise from construction equipment, blasting, and drilling activities may repel some bats, potentially causing them to find other areas for foraging and commuting. The addition of new structures in the waterways and new lighting may also impact MYGR behavior. Bats may be forced to fly over the highways or through other open areas making them more susceptible to vehicle strikes or predation. • Commuting and foraging habitat within the Action Area will be cleared during construction, some of this habitat may be allowed to revegetate yet some of this habitat may be permanently lost. • Riparian vegetation removed during construction will allow more light and noise from traffic and existing development to reach the river and tributaries, potentially repelling foraging and commuting bats. • Activities within the footprint of the proposed bridge will impact aquatic invertebrate communities and their habitats during construction, and for some time after the construction is completed. There will be some permanent loss of in-stream habitat due to the presence of new bridge bents in the river and tributaries. • Water quality impacts from construction and increased impervious surface runoff may decrease food and drinking water quality for foraging MYGR. • Bats repelled from their forage areas and commuting routes may expend additional energy finding new foraging and commuting areas, which could result in lower fitness. Pregnant and lactating females will be particularly susceptible to impacts given the increased energy demands during this time period and could lose pups due to longer flight distances to forage. 5.1.3 Factors to Be Considered – Disturbance Duration, Frequency and Intensity Gray bats in the Action Area will be affected by construction activities during the MYGR active season (mid-March through mid-November). The construction duration for Project Ranger is 14 months. Disturbance from elevated nighttime lighting and noise associated with construction will be temporary, but will exist until construction is complete. After the construction causeways are removed from the FBR, the substrate and its invertebrate population will continue to recover for some period of time as the river has bankfull flows that resort the riverbed and reestablish the riffle section. The new river crossings are likely to result in more permanent impacts from noise associated with an increase in vehicles and the addition of permanent lighting, which may impact foraging and commuting bats, including bats traveling to and from the roosts within, and outside of the Action Area. Tree clearing associated with the project will further fragment habitat and may leave openings that act as a barriers in certain locations since Myotis are reluctant to cross wide, open areas and some species of bats avoid lights and large roads (Berthinussen and Altringham 2012). Bats may temporarily abandon the onsite roost during project construction 39 due to project-mediated disturbances including increased noise, vibration, lighting, and/or habitat loss. 5.2 EFFECTS ANALYSIS – GRAY BAT 5.2.1 Beneficial Effects Beneficial effects have contemporaneous positive effects without any adverse effects to the species or habitat. The installation of bat panels at the proposed bridge may create additional roosting habitat for gray bat. Proposed monitoring during project construction would allow for the detection of alterations to MYGR foraging and/or roosting behavior, and inform prudent conservation measures intended to protect or enhance this population (see Section 2.4 for descriptions of these and other proposed conservation measures). 5.2.2 Adverse Effects – Project Construction Construction activities associated with Project Ranger will include, tree clearing, grubbing, grading, installation of base material, installation of pavement, construction of access roads, construction of causeways, blasting, pile driving, and lighting associated with night work. MYGR are present in the Action Area and most vulnerable to effects from associated construction activities during the MYGR active season (mid-March to mid-November) when flying adjacent through active construction areas and when commuting to and from the onsite roost. Stressors from project construction are generally short term in nature near the French Broad River, but short-term effects could occur periodically during the construction process (Appendix A, Figure 5). 5.2.2.1 Project Construction – Tree Clearing The Applicant indicates that Project Ranger would require up to 84 acres of tree clearing. Tree clearing along the French Broad River would total three acres. All other tree clearing activities would not occur within 400 linear feet of the French Broad River. However, tree- trimming/limbing would occur along construction access roadways (within 25 feet on either side). Some of this limbing activity for construction road widening would occur within 400 linear feet of the French Broad River, but no clearing or grubbing would occur in these areas. Tree clearing has begun for Project Ranger. By March 25, 2020, 65 acres have been cleared and the Applicant intended to accomplish as much tree clearing during winter as possible, to avoid impacts during the MYGR active season. Tree clearing up to four acres for an electrical substation may occur during the MYGR active or maternity season. While the exact location for the substation has not been determined, the Applicant indicates that its location would occur greater than 400 linear feet from the French Broad River to avoid loss of MYGR forage and commuting habitat. MYGR are forest bats that typically forage and commute in or near forested areas. The removal of riparian forest adjacent to foraging habitat could influence bats to abandon existing foraging areas, locate new foraging areas, or abandon adjacent roosts. MYGR may be forced to expend 40 increased energy to establish new foraging areas or new travel corridors between roosting and foraging. Additionally, they may be subject to an increase in inter- and intra-specific competition. Bats with high site fidelity to certain foraging areas may continue to cross through newly cleared areas in the activity footprint and may have an increased risk of mortality from predation, although this risk is not detectable or measurable. It is unclear whether MYGR that regularly forage in the Action Area will have difficulty establishing new foraging areas due to the availability of remaining suitable habitat in the surrounding landscape. Forested areas in the Action Area are largely intact and undisturbed by surrounding development activities. Along the French Broad River, there is generally a continuous, (albeit narrow in some places) riparian buffer. This buffer is important for blocking light from developments and roads on the water bodies and for providing cover for commuting and foraging bats. Tree clearing, and especially tree clearing adjacent to the French Broad River may extend the reach for project- mediated lighting disturbances (temporary or permanent) into MYGR habitats. This could result in diminished fitness of adults and/or reduced survivorship of pups and/or adults. Bats continuing to use the roost could be susceptible to increased predation because of the lack of cover. 5.2.2.2 Project Construction – Noise and Vibration The use of heavy equipment is anticipated to cause noise disturbance during construction activities within the Action Area. Noise will be generated primarily from work using heavy equipment and activities such as blasting, drilling, jackhammering, operating generators, and pile driving over the 14 month construction period. The Applicant estimates that construction of Project Ranger would require 60 total blasts over six months (August 2020 – March 2021). Noise levels from blasting can reach 126 decibels (NRC 2012). These disturbances would occur during the MYGR active season and possibly within the MYGR maternity season (Appendix A, Figure 5). Pile driving is anticipated for the installation of bridge end bents and would likely occur during the MYGR maternity season. The Applicant estimates that pile driving would take two weeks for each of the two bents, (four weeks total; Appendix A, Figure 5). Noise from pile driving can reach 110 decibels (NRC 2012). Investigative drilling for bridge construction would occur during MYGR active season. This activity would be conducted for approximately 10 hours each day and take two weeks to complete. Once investigative drilling is complete, construction drilling would take up to eight weeks to complete and would occur during the MYGR maternity season (Appendix A, Figure 5). Drilling noise and vibration will vary depending on depth of drilling bit, depth of water, and presence of sediment/silt of other substrates above underlying bedrock. Although the majority of construction will occur during the day, some construction activities will occur at night. Daytime and nighttime noise associated with these activities is expected to affect roosting, foraging, and commuting MYGR within the Action Area. Noise from nighttime construction activities will impact MYGR flying over or adjacent to construction locations. At these locations MYGR may be exposed to noise intensity that they may not have previously experienced in those locations and potentially for long durations during the MYGR active or maternity seasons. 41 Project-mediated noise and vibration during the MYGR active and maternity seasons may increase stress on pregnant and lactating females, leading to reduced fitness and pup survivorship. Noise disturbances may create an acoustic barrier that may affect foraging and commuting behavior. It is anticipated that MYGR will modify their preferred foraging and commuting areas due to increased noise associated with construction activities. If MYGR avoid areas that are noisier than they are accustomed to, and particularly if they must do so for an extended time while construction is underway, this may lead to increased travel time/distance between their roosts and foraging areas, potentially resulting in diminished fitness of adults and/or reduced survivorship of pups and/or adults. The proposed duration and intensity of noise and vibration disturbances from construction activities may reduce the suitability of the MYGR roost within the action area. Bats may abandon this roost and seek an alternate, resulting in diminished fitness of adults and/or reduced survivorship of pups and/or adults. 5.2.2.3 Project Construction – Lighting Although the majority of construction will occur during the day, the use of temporary lighting after sunset will be necessary to complete some aspects of construction. Lighting associated with construction activities will be brighter than ambient light generated by headlights or nearby overhead lighting around interchanges or near developed areas. Project-mediated disturbances from night lighting will occur during the MYGR maternity and active seasons. Construction activities requiring night work during the maternity season are as follows: • Grubbing, grading, installation of base material at the facility site not to exceed three nights total. • Earthwork to provide level roadbed and construction area not to exceed three nights total. • Use of earth-moving and road building equipment, including cranes and dump trucks not to exceed three nights total. • Concrete pours up to twice per week, 10 hours per night, not to exceed ten nights total. • Facility construction may require an undefined amount of night work. Based on the limited information provided by the Applicant for this undisclosed development, it is not currently possible for the Service to predict or estimate the duration of this activity. Myotis sp. are light averse (Voigt 2018) and the addition of night lighting will likely repel some foraging or commuting bats from lit work areas and nearby habitats. It is likely that the MYGR occupying the primary roost located within the Action Area would be exposed to this light stressor as well as bats that commute and forage from other roost sites in the region. It is likely that MYGR activity within the Action Area is highest along the French Broad River where MYGR are foraging and commuting. Therefore, construction lighting in riparian areas would likely result in the greatest light-mediated impact to bats. However, a smaller proportion of MYGR have been documented to forage or commute in heavily wooded areas along the Blue Ridge Parkway, partially wooded uplands, and areas with no associated water sources, suggesting that construction lighting in upland areas may also affect MYGR. 42 Bridge construction activities will occur within the highest quality foraging and commuting habitats within the Action Area for MYGR. Construction activities that illuminate the river or riparian areas, especially on the causeways at the river level, may deter bats from their typical foraging and commuting areas for the duration of the project construction. If MYGR avoid areas that are brighter than baseline conditions, and for an extended period of time, this may lead to increased travel time/distance between their roosts and foraging areas. Although night work lighting will be somewhat limited as described above, these disturbances may still contribute stress to pregnant and lactating females, leading to reduced fitness and pup survivorship. These activities are anticipated to have long term impacts on the local MYGR population. Since construction lighting will likely create a visual barrier, it is anticipated that MYGR will avoid or modify their preferred foraging and commuting areas, and potentially their roosting areas influenced by this disturbance. If MYGR avoid areas that are brighter than they are accustomed to, and particularly if they must do so during the entire 14 month construction duration, this may lead to increased travel time/distance between their roosts and foraging areas. This could result in diminished fitness of adults and/or reduced survivorship of pups and/or adults. Bats that continue to utilize areas that are brightly lit may experience higher levels of predation. The proposed construction lighting may reduce the suitability of the MYGR roost site. Bats may abandon this roost and seek an alternate, resulting in diminished fitness of adults and/or reduced survivorship of pups and/or adults. Bats continuing to use the roost may be susceptible to increased predation due to increased visibility. 5.2.2.4 Project Construction – Causeways and Bridge It is anticipated that the temporary fill associated with the causeways in the French Broad River, will have some effect on MYGR since these activities will occur within the highest quality foraging and commuting habitats for MYGR within the Action Area. It is difficult to predict whether the potential changes to flow velocities, and any associated increases in sedimentation produced by the temporary causeways will affect MYGR that utilize these areas for foraging or commuting. However, the causeways will temporarily reduce the available habitat for aquatic invertebrates in these streams, where MYGR are known to forage. If the prey base in this area is reduced while causeways are in place, and MYGR are forced to find other foraging areas, this may lead to increased travel time/distance between their roosts and other foraging areas. We anticipate that temporary stream fill may remain in place in various locations throughout the Action Area and may cause some MYGR to seek alternative foraging locations. However, we do not anticipate being able to measure this effect, and believe it will be insignificant. There is concern that if the hydrology of the French Broad River is altered, either temporarily during construction, or permanently as a result of construction, MYGR may find the roost site within the Action Area less desirable and abandon it. However, the Applicant has committed to ensuring that temporary causeways do not occlude greater that 64-percent of stream discharge at any given time. It is unknown how roosting, foraging, and commuting MYGR or their macroinvertebrate prey source may respond to this temporary flow alteration. However, we do not anticipate being able to measure this potential effect. 43 5.2.2.5 Project Construction – Water Quality/Erosion and Sediment Controls The Applicant has made an effort to minimize impacts to surface waters and wetlands. However, several project-mediated impacts to water quality are still likely to occur within the Action Area. These effects are anticipated to be short term in nature, and may include: ● temporary sedimentation from land-clearing and earth moving activities such as preparation, installation of drainage features, utility installation, and grading activities; ● temporary sedimentation from in-water work associated with bridge construction activities such as investigative and construction drilling for bridge footings, installation and removal of temporary causeways, and construction drilling; and ● accidental spills of petrochemicals, drilling fluid, uncured concrete, et cetera. The proposed project would directly impact (fill) 0.067 acre of wetland and 277 linear feet of the French Broad River. At least 13,500 linear feet of stream and 2.891 acres of wetland occur within the Action Area. Most of these are small streams and wetlands, which MYGR do not typically utilize for foraging and commuting, but indirect impacts to these features associated with construction activities may contribute to diminished water quality within the Action Area. Diminished water quality caused by sedimentation, contamination, and the destruction of wetlands and stream habitats where MYGR are present may reduce the availability of certain aquatic invertebrates and/or reduce the quality of suitable drinking sources. Insects associated with aquatic habitats comprise a large portion of the MYGR diet. Many species of aquatic insects are intolerant of even subtle perturbations to water quality and physical habitats. Therefore, a change in water quality may affect a portion of the prey base of the species. Although water quality impacts may cause a reduction in specific portions of the prey base and diminish the quality of drinking sources for MYGR, adverse effects will be temporary, and are likely to be undetectable due to the availability of alternative prey and drinking sources in the surrounding landscape. MYGR diet has been found to coincide most directly with the predominantly available prey species in the foraging area (including both terrestrial and aquatic species). This suggests that bats may be capable of sufficiently modifying their diet and forage areas to adapt to changes in hydrology and any associated changes to community structure of invertebrate prey. Therefore, we do not anticipate any measurable effect on MYGR due to potentially diminished water quality. 5.2.2.6 Project Construction – Summary of Effects Lighting, noise, removal of woody vegetation, reduced water quality, stream fill and associated aquatic habitat alteration/destruction, could adversely impact MYGR. Project-mediated impacts to the primary roost within the Action Area and to riparian and instream habitats associated with the French Broad River are anticipated to have the most significant effects on MYGR as these areas represent the highest quality habitats for the species. Specifically, construction lighting, noise, vibration, and the removal of woody vegetation for the construction of the proposed bridge are anticipated to be the activities resulting in the greatest impact to MYGR. Reduced water quality, stream fill, and modifications to hydrology have effects to MYGR that are not as well understood, and harder to quantify, but are nevertheless predicted to have some negative effect. In total, construction effects from these stressors are likely to adversely affect MYGR by 44 potentially diminishing the fitness of adults and/or reducing the survivorship of pups and/or adults. Mortality is possible if roosting bats are disturbed from torpor in March and after October 15th from associated work. 5.2.3 Adverse Effects – Project Operations The nature of project operations is unknown as the Applicant has not disclosed several key aspects of its proposed development including what it will produce and how the facility would be operated. The Applicant describes Project Ranger as an economic development project with an extremely sensitive construction schedule. The Applicant indicates that it will plat and dedicate an 89-acre tract of land for the undisclosed manufacturing facility, but it is unclear when this would occur and who would own this property. Based on the information provided, we can surmise the following project-mediated effects to MYGR from Project Ranger operations. 5.2.3.1 Project Operations – Vehicle Lighting Once the proposed roadway is in operation, traffic volume and ambient light from headlights will increase from baseline conditions to support approximately 1,200 employees and any additional traffic that may use the Action Area as a thoroughfare in the future. MYGR travelling across or adjacent to the roadway, particularly in areas near the French Broad River would be most susceptible to impacts associated with increased ambient light. Myotis sp. are light averse (Voigt 2018) and additional ambient lighting will likely repel some foraging or commuting bats from affected areas. If bats choose to avoid newly lit areas, they will need to find new travel corridors and foraging areas and could be impacted for some amount of time post-construction. Potential impacts include increased energy expenditure affecting fitness and reproductive success. 5.2.3.2 Project Operations – Noise Once Project Ranger is operational affects from noise associated with increased traffic volume and project operations will become permanent and will likely increase from baseline conditions. Since little has been disclosed about Project Ranger operations, it is not currently possible to predict how noise levels associated with project operations will increase from baseline conditions once the project becomes operational. Although, we surmise that MYGR travelling across or adjacent to the roadway during the MYGR active and maternity seasons would be exposed to increased noise, and project-mediated noise disturbances that occur after sunset (night traffic or night operations) may be most harmful to the species. While there are no studies that quantify a noise tolerance threshold that elicits a deleterious response to foraging, commuting or roosting MYGR, some studies suggest that roosting Myotis sodalis (MYSO, congener) may be able to tolerate noise disturbance from vehicle traffic near large airports (Sparks et al. 2009). It should be noted that MYGR using roosts in bridges near the Action Area (Appendix A, Figure 9) are accustomed to at least some level of noise disturbance which is commensurate with baseline traffic and development conditions. However, 45 most of these known bridge roosts are located on two-lane roads with lower traffic volumes than those anticipated with this project. Since Project Ranger operations have not been disclosed, and little is currently known about the relationship between noise disturbances and MYGR behavior, it is not currently possible to predict how additional noise disturbance may affect roosting, foraging, and commuting MYGR within the Action Area over the lifetime of the project. However, we are reasonably certain that project-mediated noise disturbance will increase from baseline conditions within the Action Area once the project becomes operational. 5.2.3.3 Project Operations – Vehicle Collisions Bats attempting to cross the Action Area will encounter a wider opening between areas of vegetated refugia compared to baseline conditions, and will encounter new openings and obstacles where the bridges are constructed. MYGR attempting to cross the roadway could be struck by passing vehicles. Bats may be more likely to collide with cars when they are first confronted with the new bridge and roadway, potentially deciding to fly over them. Collisions would be more likely to occur with lower bridges and the risk would likely decrease as bats adjust to the structures. Bat mortality caused by impacts with passing vehicles is well documented (Kiefer et al. 1995, Lesiński 2007, Gaisler et al. 2009, Russell et al. 2009, Lesinski et al. 2010, Medinas et al. 2013). Bat mortality may occur within the Action Area if bats fly too low in traffic when crossing over a bridge or roadway, typically when they are commuting. MYGR are probably less susceptible to vehicle collisions while foraging, because they typically forage within 6.5 to 10 ft. of the water surface (Tuttle 1976b, 1979, LaVal et al. 1977). Bat injury and mortality from vehicle strikes is likely to increase within the Action Area from baseline conditions due to increased traffic. Direct impacts to MYGR from vehicle collisions would likely result in death or injury. Bats that choose to avoid areas with increased traffic may seek new travel corridors, foraging areas, or roosts, which may require that they expend additional energy affecting fitness and reproductive success. 5.2.3.4 Project Operations – Site Maintenance Although the Applicant has not disclosed key aspects of Project Ranger operations, forested areas that are cleared as part of the construction process will likely need to be maintained in low growing or herbaceous vegetation after construction completion. Potential effects to MYGR from woody vegetation removal are described in Section 5.2.2.1. Maintenance of cleared areas near water will result in a permanent increase in lighting from road work and facility operation and reduced cover for foraging and commuting bats. Openings in forest cover will be relatively small in size within 400 linear feet of the French Broad River, where the highest quality habitats for foraging and commuting MYGR occur within the Action Area. Based on the information available, it is difficult to fully assess how the maintenance of these open spaces will affect MYGR within the Action Area. However, we anticipate that bats will eventually adjust to vegetation changes and will likely find alternative dark corridors for commuting and foraging, as needed. Additionally, tree trimming and hazardous tree removal activities would likely occur along roadsides to reduce safety hazards from falling trees or limbs, or to improve line-of-sight issues. 46 Hazardous tree-removal would likely occur on an as-needed basis, so quantifying the amount of habitat lost from this activity is not practicable. No MYGR roosts are anticipated to be impacted by this activity, and any clearing of this type along waterways where MYGR might be foraging or commuting is expected to be minimal. Based on the information provided, we do not anticipate any detectable effects mediated by site maintenance on MYGR that occur in the Action Area. 5.2.3.5 Project Operations – Permanent Lighting The BA indicates that permanent lighting for the Project Ranger facility would comply with Buncombe County lighting standards, which are intended to minimize light pollution, light trespass and glare, and promote energy efficiency (Buncombe County, 2019). The Project would use warmer color temperature lighting (CCT < 3,000K), utilize LED light fixtures with lumen output equal to or less than Buncombe County requirements, and employ downward-facing fully shielded lighting. The mounting height of all outdoor area lighting would not exceed 25 feet above the lowest adjacent elevation. The permanent lighting design for the French Broad River bridge calls for two lights at the center of the bridge, and two additional lights (six lights total) at each of the bridge abutments (Appendix, Figure 7). The bridge and roadway would use Type II LED light fixtures with a 1-0- 1 BUG rating which are designed to minimize light spill. Additional permanent lighting would be constructed near the bridge intersection with NC-191 on the west side of the river (Appendix A, Figure 7). The baseline condition for much of the foraging and commuting habitat on the French Broad River is unlit, with some small areas of light from existing bridges and private development. Light does not typically reach all the way across any of the waterways. Once the Project Ranger construction is complete, MYGR travelling across or adjacent to the Action Area, will be exposed to new lighting. Since Myotis sp. are light averse (Voigt 2018), additional ambient lighting will likely repel some foraging or commuting bats from affected areas. If bats choose to avoid newly lit areas, they will need to find new travel corridors and foraging areas and could be impacted for some amount of time post-construction. Potential impacts include increased energy expenditure affecting fitness and reproductive success. Permanent lighting at the project may reduce site suitability to the extent that MYGR abandon the roost located within the action area. Bats may abandon this roost and seek an alternate, resulting in diminished fitness of adults and/or reduced survivorship of pups and/or adults. Bats continuing to use the roost may be susceptible to increased predation due to increased visibility. The Applicant proposes to monitor this MYGR population while Project Ranger construction is underway (Section 2.4.9). More importantly, the NCDOT proposes to monitor this MYGR population while construction of nearby roadway projects are underway (estimated 2022-2027 according to BA), which coincides with the start of Project Ranger operations. Biltmore Farms has committed to allow access to the site for the purposes of monitoring bat populations for the duration of Project Ranger and NCDOT I-26 construction projects (Section 2.4.9). This 47 monitoring effort is intended to document potential population declines, roost abandonment, roost establishment, and/or roost re-establishment that may occur. 5.2.4 Adverse Effects – Project-Meditated Consequences Effects of the action are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action. A consequence is caused by the proposed action if it would not occur but for the proposed action and it is reasonably certain to occur. Effects of the action may occur later in time and may include consequences occurring outside the immediate area involved in the action. (See § 402.17). 5.2.4.1 Consequences Affecting Gray Bat – Induced Land Development The Applicant describes Project Ranger as an economic development project with an extremely sensitive construction schedule but also indicated that the undisclosed industrial developer was considering multiple construction locations throughout the southeastern U.S. It is unclear when, or if the undisclosed industrial developer has committed to development of the project. At this time, Biltmore Farms has not disclosed what the 1,000,000 square foot facility would produce, who would employ its estimated 1,200 employees, or described project operations with detail. However, we believe that Project Ranger will likely induce changes in surrounding land use based on the information provided in the BA. Specifically, the proposed bridge/roadway alignment and design, significant employee recruitment, and the Applicant’s intent to bolster additional economic development suggest that Project Ranger would facilitate additional development activities in the vicinity of the Action Area. Design plans call for the grading of an area along the roadway to accommodate a round-about that could provide future roadway access to an undeveloped tract of Biltmore Farms property south of the Blue Ridge Parkway (Appendix A, Figure 3). The Applicant indicates that grading for this round-about would be accomplished during the initial phase of development to avoid disruption of Project Ranger operations in the future, and that the roundabout would allow future traffic from the south to return to the proposed bridge without entering the Project Ranger facility. The Applicant also indicates that the bridge and access road would be turned over to the NCDOT for upkeep beginning March, 2021. The NCDOT expressed their intent to add the proposed access road and bridge into the state system of maintenance once construction is complete (Appendix E). Therefore, the proposed roadway and bridge are designed to meet minimum NCDOT standards. No plans (conceptual, draft, final, or otherwise) for onsite or offsite development associated with Project Ranger have been provided at this time. Based on the information provided by the Applicant and summarized above, future development associated with the proposed project is reasonably certain to occur but it is unclear what exactly will necessitate the expansion of this roadway, when it would occur, and what future development activities it would accommodate. At this time, it is not possible to measure the effects that induced development activities may have on roosting, foraging, or commuting MYGR. However, we anticipate that project-mediated induction of additional residential and commercial developments in the area would have at least some negative impact on MYGR. Impacts to MYGR from induced development would likely be 48 similar in nature to those described above, and development activities would have the greatest impact during the MYGR active and maternity seasons and within areas along the French Broad River (particularly the primary roost site within the Action Area). 5.3 EFFECTS OF THE ACTION – APPALACHIAN ELKTOE Under section 7(a)(2) of the Act and the recent update to the regulations, effective October 28, 2019, “effects of the action” are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action. A consequence is caused by the proposed action if it would not occur but for the proposed action and it is reasonably certain to occur. Effects of the action may occur later in time and may include consequences occurring outside the immediate area involved in the action. The federal agency is responsible for analyzing these effects. The effects of the proposed action are added to the environmental baseline to determine the future baseline, which serves as the basis for the determination in this Opinion. Should the effects of the federal action result in a situation that would jeopardize the continued existence of the species, we may propose reasonable and prudent alternatives that the federal agency can take to avoid a violation of section 7(a)(2). 5.3.1 Factors to Be Considered – Proximity of the Action Appalachian elktoe occurs within a portion of the Action Area, specifically the main stem of the French Broad River (Figure 8 of Appendix A). Freshwater mussel surveys were conducted October 4, 2019. The survey area was conducted from approximately 400 meters downstream of the proposed bridge footprint to 100 meters upstream from the proposed bridge footprint. Approximately 21 person-hours detected two mussel species including, one live Appalachian elktoe mussel (catch-per-unit-effort was 0.05 Appalachian elktoe/hr). 5.3.2 Factors to Be Considered – Nature of the Effect Project-mediated construction disturbances will impact Appalachian elktoe habitat and may directly impact (kill, crush, bury) individual mussels within the Action Area. Once construction is complete, project operations associated with Project Ranger will continue to impact Appalachian elktoe habitat within the French Broad River. The nature of project-mediated effects to Appalachian elktoe are summarized below: • Riparian vegetation removed during construction will increase the risk of erosion and sedimentation to instream habitats occupied by Appalachian elkote. Maintenance of these cleared areas (preventing natural revegetation of deep rooting native woody species) once Project Ranger is operational will also maintain the risk of erosion and sedimentation of instream habitats. • Activities within the footprint of the proposed bridge will impact the mussel community and their habitats during construction, and for some time after the construction is completed. There will be some permanent loss of in-stream habitat due to the presence of new bridge bents in the river and tributaries. 49 • Lighting, noise, and vibration from construction equipment, blasting, and drilling activities may cause mussels to retract siphons and close valves which may disrupt feeding, respiration, and reproductive behaviors, including those associated with their fish symbionts. • Water quality impacts from construction and project operations will increase impervious surface runoff and may decrease physical habitats and water quality for Appalachian elktoe. 5.3.3 Factors to Be Considered – Disturbance Duration, Frequency, and Intensity Appalachian elktoe within the Action Area may be affected during the entire 14 month construction duration for Project Ranger, but bridge and causeway construction activities are the most likely to cause direct impacts to this species (Appendix A, Figure 5). The causeways for construction and demolition will be in place for the length of time needed to construct and demolish the bridges. Although there will be direct impacts to the riverbed associated with the causeways, the construction of the causeways will be phased to limit the amount of causeway in the river at any one time, and only the causeways needed for an activity will be in place during that activity and will be removed when the action is completed. There will be temporary impacts to river hydrology both upstream and downstream of the causeways. The Applicant has committed to ensuring that temporary causeways do not occlude greater that 64-percent of stream discharge at any given time. After the construction causeways are removed from the French Broad River, the benthic community will continue to recover for some period of time as physical habitats endure seasonal bankfull flows that resort the riverbed and reestablish meso-habitats. Therefore, the intensity of this project-mediated disturbance would attenuate over time following project completion. Project-mediated disturbances to uplands have potential to induce erosion and sedimentation of Appalachian elktoe habitat within the Action Area throughout the entire construction duration (Appendix A, Figure 5). Water supply and gas utility lines may be directionally bored under the French Broad River (minimum depth of six feet) at the bridge crossing location (Appendix C), and may impact Appalachian elktoe in the case of an inadvertent spill of drilling fluid However, appropriate sediment and erosion control measures and a frac-out contingency plan (Appendix C), would reduce the probability for large inputs of sediment or spilled fluid into the French Broad River, thereby reducing the intensity of these effects to Appalachian elktoe. 5.4 EFFECTS ANALYSIS – APPALACHIAN ELKTOE 5.4.1 Beneficial Effects The Applicant, Biltmore Farms, has committed to provide $15,000 in funding to the North Carolina Nongame Aquatic Projects Fund for the French Broad River Conservation Plan (FBRCP) proposed by USFWS, which will aid in the recovery and conservation of Appalachian Elktoe and other associated freshwater mussel fauna of the French Broad River. 50 5.4.2 Adverse Effects – Project Construction Construction activities associated with Project Ranger will include, tree clearing, grubbing, grading, installation of base material, installation of pavement, construction of access roads, including a new bridge across the French Broad River, construction of causeways, blasting, pile driving, and lighting associated with night work. The Action Area includes a reach of the French Broad River that is occupied by Appalachian elktoe and instream construction activities may result in direct impacts to this species. Additionally, the majority of uplands within the Project Area also drain into the French Broad River. Therefore, certain construction disturbances occurring in riparian areas and uplands may also affect the Appalachian elktoe and its habitats. Appalachian elktoe present in the Action Area may be most vulnerable to disturbance effects from associated construction activities when females prepare to release maturing glochidia to infest susceptible fish symbionts. 5.4.2.1 Project Construction – Vegetation Removal The Applicant indicates that Project Ranger would require up to 84 acres of tree clearing. Tree clearing along the French Broad River would total three acres. No other tree clearing activities would occur within 400 linear feet of the French Broad River. However, tree-trimming/limbing would occur along construction access roadways (within 25 feet on either side). Some of this limbing activity for construction road widening would occur within 400 linear feet of the French Broad River, but no clearing or grubbing would occur in these areas. Forested areas in the Action Area are largely intact and undisturbed by surrounding development activities. Along the French Broad River, there is generally a continuous, (albeit narrow in some places) riparian buffer. This buffer is important for maintaining instream and riparian habitats as it stabilizes streambanks, catches and filters runoff, maintains suitable air and water temperatures, and provides a source of coarse woody debris and allochthonous organic matter to maintain physical habitat diversity and the aquatic food web. Reduced function of the adjacent forested riparian corridor may lead to short-term perturbations to water quality and physical habitats that could reduce fitness of individuals. Tree clearing, and especially tree clearing adjacent to the French Broad River may extend the reach for project-mediated lighting disturbances (temporary or permanent) into Appalachian elktoe habitats. Lighting disturbances may cause mussels to retract siphons and close valves which could disrupt feeding, respiration, and reproductive behaviors, (including those associated with their fish symbionts), and could reduce fitness of individuals. Prolonged exposure to lighting disturbances exceeding baseline conditions may influence animals to expend resources or prematurely abort glochidia which could reduce reproductive success and increase susceptibility to predation or otherwise reduce fitness. 5.4.2.2 Project Construction – Bridge and Causeways Construction work in or adjacent to the French Broad River has a greater potential to affect Appalachian elktoe due to its immediate proximity to occupied habitat, compared to construction 51 activities within uplands that drain into the river. The following activities associated with bridge construction may adversely affect the Appalachian elktoe. During investigative drilling for bridge footings, any mussels present in the drilling area, (less than two sq. ft. in the French Broad River), will be killed. The cuttings (rock dust) from drilling could potentially smother any mussels that occur in the area. Given the rarity of Appalachian elktoe within the French Broad River, the chances of an individual occurring within the location of the borings is small but cannot be completely discounted. Bridge construction would include temporary impacts to 0.67 acres of the French Broad River for causeways, <0.01 acre of permanent fill for bridge footings, and 0.03 acre of permanent bank stabilization (riprap) on both banks. Any mussels present in the bridge construction areas could be killed by drilled shafts or placement of footings, placement of causeways, and/or the removal of causeways. Bridge Construction – Causeways The placement and removal of causeways will likely have the greatest impact to Appalachian elktoe of all proposed construction activities. Causeway installation and removal activities may directly kill, crush, or bury individual mussels and may cause temporary negative effects to physical habitats. Causeways would constrict river discharge and therefore modify the hydrology and physical habitat conditions upstream and downstream of the construction area to an extent that will depend on flow conditions. High-flow events will likely exacerbate the influence of causeways to alter baseline hydrology and physical habitat conditions. Rock causeway material may be washed away during high flow events, which may kill, crush or bury individuals or otherwise degrade mussel habitat. The Applicant has committed to ensure that temporary causeways do not occlude greater that 64- percent of stream discharge at any given time. Still, causeways will increase the risk of stream bed and bank scour within the Action Area. The area downstream of the causeways will experience higher velocities while causeways are in place and may experience higher rates of scour as a result. Scouring could affect any mussels in the riverbed, washing them downstream and/or causing shell erosion. Mussels that occur upstream or downstream of temporary causeways may be involuntarily displaced by higher flow conditions or may voluntarily relocate to find more favorable conditions for feeding or reproductive behaviors. Animals that expend energy adapting to altered baseline habitat conditions may increase susceptibility to predation or otherwise experience a reduction in fitness or reproductive success. Since habitat in the French Broad River is bedrock dominant, the Service believes this habitat will likely revert back to its present suitability within a few years post construction. Temporary causeways may also act as physical, and high-velocity barriers to fish movement. The disruption of fish movement could impact the Appalachian elktoe if its fish hosts are unable to move freely in the French Broad River. Disruptions to fish movement may cause loss in mussel recruitment in upstream or downstream areas for the period of time the causeways are in place. Fish hosts traveling upstream are more likely to encounter this disruption than those 52 traveling downstream. Although this impact could affect the reproductive success of Appalachian elktoe within the Action Area, the Service believes that project-mediated impacts to its host fish would be minor. All potential impacts to Appalachian elktoe mentioned above associated with bridge construction activities may induce erosion and sedimentation within the Action Area. However, land disturbances associated with accessing the river for construction is likely to be the greatest source of sedimentation. 5.4.2.3 Project Construction – Water Quality/Erosion and Sediment Controls The Applicant has proposed measures to minimize impacts to surface waters and wetlands. However, several project-mediated impacts to water quality are still likely to occur within the Action Area. These effects are anticipated to be short term in duration, and may include: ● temporary sedimentation from land-clearing and earth moving activities such as preparation and installation of drainage features, utility installation, and grading activities; ● temporary sedimentation from in-water work associated with bridge construction activities such as investigative and construction drilling for bridge footings, installation and removal of temporary causeways, and construction drilling; and ● accidental spills of petrochemicals, drilling fluid, uncured concrete, or other construction liquids. The proposed project would directly impact (fill) 0.067 acre of wetland and 277 linear feet of the French Broad River. At least 13,500 linear feet of stream and 2.891 acres of wetland occur within the Action Area. Most of these are small streams and wetlands, which Appalachian elktoe do not occupy. However, impacts to conveyances that drain into the French Broad River may degrade water quality and physical habitats within the Action Area. All construction activities that expose soil create an opportunity for soil erosion and sedimentation into the French Broad River. This can negatively impact aquatic species, including the Appalachian elktoe. Given the extent of project-mediated disturbance, Project Ranger has significant potential to cause widespread, negative effects to Appalachian elktoe and its habitat during project construction. Two previous population declines of this species coincided with erosive events. In the Little Tennessee River, hurricanes Frances and Ivan in 2004 caused major flooding resulting in landslides and chronically unstable banks throughout the watershed. Over the next few years, the population of Appalachian elktoe declined precipitously and is now critically imperiled. On the South Toe River, starting in 2013 a major road widening project began affecting dozens of tributaries of the South Toe River. Subsequently, the Appalachian elktoe population immediately downstream of this disturbance declined. Investigations into the mechanism that caused the decline are ongoing, but the proximity to potential erosive sources suggests that this species is particularly sensitive to elevated levels of fine sediment. 53 The distribution of Appalachian elktoe in the French Broad River currently places most of them in the upper portions of the river (mainstem and tributaries in Henderson and Transylvania Counties, North Carolina). At this time, Appalachian elktoe appears to be expanding its range in the French Broad River. Species occurrence records suggest that downstream expansion of the Appalachian elktoe will continue unless external factors halt the population expansion. Due to the above mentioned losses in two other populations, the long term stability of the French Broad River population is critical for species recovery. The erosion control measures incorporated into the proposed action will reduce the levels of sedimentation into the French Broad River, but these measures have a design limit based on the amount of rainfall received at the project area. Rainfall events that are greater than the erosion control design limits will result in sediment loss into the river. The baseline levels of suspended sediment in the French Broad River are elevated due to cumulative activity in the watershed. However, this baseline suspended sediment has not prevented recent population expansion. In 2018 the Asheville region experienced the highest level of rainfall on record. Until that time, the previous record year was 2013. Since the frequency of record high rainfall events in the area seem to be increasing, it is possible that periods of significant rainfall will occur during the construction period (Appendix A, Figure 5). 5.4.2.4 Project Construction – Utility Line and Frac-Out Project design plans are not complete at this time, but the Applicant anticipates that water supply and gas utility lines would be directionally bored under the French Broad River (minimum depth of six feet) at the bridge crossing location, then run along the road alignment depicted in design plans (Appendix A, Figures 3 and 4; Appendix C). Inadvertent frac-out and/or spill of drilling fluid may suffocate, injure, or otherwise reduce fitness of mussels occurring within a localized area of effect. The Applicant has prepared a frac- out contingency plan that requires contractors to contain any spilled drilling fluid and minimize environmental impacts (Appendix C). Notably, the frac-out contingency plan calls for a vacuum truck to remain onsite to facilitate containment in case of an inadvertent spill. Spills associated with frac-outs are rare and depend on underlying geology and drilling methods. Given the apparently low density of Appalachian elktoe within the French Broad River, and proposed measures to contain an inadvertent spill of drilling fluid, the probability of this impact is very low but cannot be completely discounted. 5.4.2.5 Project Construction – Inadvertent Spills The inadvertent spill or discharge of toxic pollutants, such as diesel fuel, hydraulic oil, and uncured concrete into the French Broad River could result in mortality of Appalachian elktoe. Spills of construction fluids are not uncommon, and the duration of heavy equipment use adjacent to waterways increases the possibility that a spill or discharge could occur. However, the Applicant has committed to conservation measures that reduce the likelihood of a spill or discharge reaching the river (see Section 2.4 for a description of this and other proposed conservation measures). Spills could also take place near any other waterway within the Action Area and subsequently have an effect further downstream. 54 The type, timing, amount, and proximity to a water source of any accidental spills would determine the magnitude of effect to Appalachian Elktoe, but may result in death, disrupt feeding or reproductive behaviors, influence animals to expend energy to relocate to more favorable habitats, or otherwise reduce fitness. Significant spills resulting from negligent operation are possible, but unlikely to occur. 5.4.2.6 Project Construction – Light, Noise, and Vibration Freshwater mussels can detect and respond to changes in light. Studies suggest that mussels may react more to rapid changes in ambient light levels (e.g. passing shadows from adjacent activity) than to gradual changes in light levels (Braun and Faust 1954, Imlay 1968). Some mussels may release glochidia (possibly prematurely) in response to changes in ambient light, noise, and/or vibration (B. Hamstead pers. comm.). Lighting, noise, and vibration disturbances may cause mussels to retract siphons and close valves which could disrupt feeding, respiration, and reproductive behaviors, (including those associated with their fish symbionts), and could reduce fitness of individuals. Prolonged exposure to these disturbances exceeding baseline conditions may influence animals to expend additional resources to relocate or prematurely abort glochidia which could reduce reproductive success and increase susceptibility to predation or otherwise reduce fitness. 5.4.3 Adverse Effects – Project Operations The nature of project operations is unknown as the Applicant has not disclosed several key aspects of its proposed development including what it will produce and how the facility would be operated. The Applicant describes Project Ranger as an economic development project with an extremely sensitive construction schedule. The Applicant indicates that it will plat and dedicate an 89-acre tract of land for the undisclosed manufacturing facility, but it is unclear when this would occur and who would own this property. Based on the information provided, we can surmise the following project-mediated effects to Appalachian Elktoe from Project Ranger operations. 5.4.3.1 Project Operations – Site Maintenance Although the Applicant has not disclosed key aspects of Project Ranger operations, forested areas that are cleared as part of the construction process will likely need to be maintained in low growing or herbaceous vegetation after construction completion. Potential effects to Appalachian elktoe from vegetation removal are described in Section 5.4.2.1. Openings in forest cover will be relatively small in size within 400 linear feet of the French Broad River. Based on the information available, it is difficult to fully assess how the maintenance of these open spaces will affect Appalachian elktoe within the Action Area. Siltation and chemical contaminants including pesticides are recognized as a threat to freshwater mussels (Williams et al. 1993, Bringolf et al. 2007). The use of herbicide near conveyances to the French Broad River has the potential to adversely effect the water quality through drift or direct runoff into the river, which may affect fitness of individuals. 55 5.4.3.2 Project Operations – Impervious Surfaces The proposed impervious area on the Biltmore Farms Tract north of the Blue Ridge Parkway will be 41.57 acres to accommodate the manufacturing facility, parking areas, bridge, access road, and roundabout (including future expansion areas) (Appendix A, Figures 3 and 4). The addition of this impervious surface drainage to baseline conditions will affect water quality and physical habitats within the French Broad River indefinitely. Impervious surfaces from roadways and developments increase the rate of runoff into the river, causing potential destabilization of sensitive habitat within. Roadway and parking lot runoff contains pollutants that may affect aquatic species at high concentrations. The Applicant has incorporated stormwater control measures into the design of Project Ranger (Appendix A, Figure 3; Sections 2.3.1.2 and 2.4). The Applicant indicates that permanent post-construction stormwater control measures would be designed to meet Buncombe County standards which require treatment of the 1-year, 24-hour storm event. Buncombe County standards also require that the design rate of discharge not exceed the pre-development rate of discharge for this same storm event. To meet these standards, Biltmore Farms proposes to construct two stormwater ponds during the initial phase of construction (Appendix A, Figure 3; Sections 2.3.1.2 and 2.4). These structures are intended to accommodate future site expansion. The outlets for these ponds will be directed away from wetlands and will be located on high ground at least 500 linear feet from the French Broad River. Their discharge will be into non-jurisdictional conveyances that drain into jurisdictional streams. While proposed stormwater control measures are intended to reduce some of the deleterious effects of project-mediated stormwater to habitat conditions within the French Broad River, they are not designed to completely eliminate stormwater-mediated shift to baseline habitat conditions, especially when rainfall surpasses design specifications. We anticipate that the proposed increases to impervious surfaces will elicit a flashier response to streamflow in project receiving waters. Increased stream velocities may have adverse erosive effects on jurisdictional or non-jurisdictional conveyances resulting in additional sedimentation in the river. Moreover, project-mediated runoff will likely degrade water quality conditions in receiving waters when rainfall events exceed the capacity of the stormwater ponds. Numerous pollutants have been identified in runoff from roadways, parking lots, and other impervious surfaces associated with developments, including various metals (e.g., lead, zinc, iron), sediment, pesticides, de-icing salts, nutrients (nitrogen, phosphorus), and petroleum hydrocarbons and many of these can be harmful to mussels. Mussels present in the Action Area may experience locally increased exposure to runoff from Project Ranger. The effects from project-mediated runoff will be long-lasting, spanning the life of the development, but significant deleterious effects will likely be sporadic and localized. The long term effects of chronic exposure to roadway pollutants to mussels are poorly understood. The proposed conservation funding committed to by the Applicant for activities aiding in the conservation of Appalachian elktoe will be expended to further study the health of the watershed, as well as the elktoe, to aid in recovery of the species. Project operations will also increase the probability for inadvertent toxic spills over the life of the development that could affect Appalachian elktoe habitat. The project-mediated effect will depend on what the undisclosed development may produce, and the frequency and means by 56 which it would be transported offsite. The effect of toxic spills from additional vehicle traffic is also difficult to predict, but the Applicant estimates the addition of approximately 2,000 vehicles per day to baseline conditions. Depending on the substance, quantity, and duration of exposure, and other unforeseen factors, toxic spills may have acute or chronic effects to Appalachian elktoe that may cause death or otherwise reduce fitness. 5.4.4 Consequences Affecting Appalachian Elktoe Effects of the action are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other activities that are caused by the proposed action. A consequence is caused by the proposed action if it would not occur but for the proposed action and it is reasonably certain to occur. Effects of the action may occur later in time and may include consequences occurring outside the immediate area involved in the action. (See § 402.17). 5.4.4.1 Consequences Affecting Appalachian Elktoe – Induced Land Development The Applicant describes Project Ranger as an economic development project with an extremely sensitive construction schedule but also indicated that the undisclosed industrial developer was considering multiple construction locations throughout the southeastern U.S. It is unclear when, or if the undisclosed industrial developer has committed to development of the project. At this time, Biltmore Farms has not disclosed what the 1,000,000 square foot facility would produce, who would employ its estimated 1,200 employees, or described project operations with detail. However, we believe that Project Ranger will likely induce changes in surrounding land use based on the information provided in the BA. Specifically, the proposed bridge/roadway alignment and design, significant employee recruitment, and the Applicant’s intent to bolster additional economic development suggest that Project Ranger would facilitate additional development activities in the vicinity of the Action Area. Design plans call for the grading of an area along the roadway to accommodate a round-about that could provide future roadway access to an undeveloped tract of Biltmore Farms property south of the Blue Ridge Parkway (Appendix A, Figure 3). The Applicant indicates that grading for this round-about would be accomplished during the initial phase of development to avoid disruption of Project Ranger operations in the future, and that the roundabout would allow future traffic from the south to return to the proposed bridge without entering the Project Ranger facility. The Applicant also indicates that the bridge and access road would be turned over to the NCDOT for upkeep beginning March, 2021. The NCDOT expressed their intent to add the proposed access road and bridge into the state system of maintenance once construction is complete. Therefore, the proposed roadway and bridge are designed to meet minimum NCDOT standards (Appendix E). No plans (conceptual, draft, final, or otherwise) for onsite or offsite development associated with Project Ranger have been provided at this time. Based on the information provided by the Applicant summarized above, future development associated with the proposed project is 57 reasonably certain to occur but it is unclear what exactly will necessitate the expansion of this roadway, when it would occur, and what future development activities it would accommodate. At this time, it is not possible to measure the effects that induced development activities may have on Appalachian elktoe. However, we anticipate that project-mediated induction of additional residential and commercial developments in the area would have at least some negative impact on water quality and physical aquatic habitats associated with an increase in impervious surfaces, stormwater conveyances into the French Broad River, untreated runoff, and toxic spills. Impacts to Appalachian elktoe from induced development would likely be similar in nature to those described above, and development activities would have the greatest impact within areas adjacent to the French Broad River. 6. CUMULATIVE EFFECTS Gray bat and Appalachian elktoe Cumulative effects are defined under the ESA as "those effects of future state or private activities, not involving Federal activities, that are reasonably certain to occur within the Action Area of the Federal action subject to consultation" (50 CFR 402.02). Future federal actions unrelated to the proposed action are not considered because they require separate consultation pursuant to Section 7 of the ESA. The Applicant describes its undisclosed development as an economic development project that would employ its estimated 1,200 employees and is therefore likely to induce changes in surrounding land use. Specifically, the proposed bridge/roadway alignment and design, significant employee recruitment, and the Applicant’s intent to bolster additional economic development suggest that Project Ranger would accommodate and/or incentivize future residential, commercial, and industrial development in the area. Additional development activities and associated impacts to MYGR and Appalachian elktoe mediated are reasonably certain to occur and these activities would likely result in similar impacts to those described above. However, we anticipate that the majority of future development activities large enough in scope to adversely affect MYGR and Appalachian elktoe would likely require federal authorization or funding requiring their own ESA Section 7 consultation, and would not be considered a cumulative effect under the ESA. However, the French Broad River corridor throughout the action area continues to experience heavy growth, with many small developments contributing non-point source pollution to the river in the form of sedimentation during construction and/or increased runoff carrying pollutants from the roads or private lands during rain events. 7. CONCLUSION 7.1 GRAY BAT After reviewing the current status of the gray bat; the environmental baseline for the action area; the effects of construction and operation of Project Ranger; conservation measures incorporated into the proposed action; effects from consequences of the action; and any cumulative effects, it 58 is the USFWS’s opinion that implementing this project is not likely to jeopardize the continued existence of the gray bat. The gray bat population utilizing the FBR basin is estimated at 1,900 to 2,300, and the entire gray bat population is conservatively estimated at 4,358,263. This project will impact less than 0.001% of the gray bat population. Therefore, it is the opinion of the USFWS that Project Ranger is not likely to result in jeopardy to the gray bat. No critical habitat for gray bat exists within the Action Area, therefore, none will be affected. 7.2 APPALACHIAN ELKTOE After reviewing the current status of the Appalachian elktoe; the environmental baseline for the action area; the effects of construction and operation of Project Ranger; conservation measures incorporated into the proposed action; effects from consequences of the action; and any potential cumulative effects, it is the USFWS’s opinion that implementing this project is not likely to jeopardize the continued existence of the Appalachian elktoe. Only a very small amount of in stream habitat will be permanently lost due to the bridge construction. Due to the extent and duration of this project, it is possible Appalachian elktoe in the Action Area will be affected by habitat degradation from sediment eroded from the project and from the degradation of channels receiving additional stormwater from the project. However, while we anticipate that Appalachian elktoe within the Action Area may be harmed by the presence of turbidity or settling of sediment in depositional portions of its habitat, we expect this effect to be non-lethal temporary harm to adults that will not reach a level that prevents recolonization of the Action Area after construction. No critical habitat for Appalachian elktoe exists within the Action Area, therefore, none will be affected. 8. INCIDENTAL TAKE STATEMENT Section 9 of the Act and federal regulations pursuant to section 4(d) of the Act prohibit the taking of endangered and threatened species, respectively, without special exemption. Take is defined as to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct. Harm is further defined by the USFWS to include significant habitat modification or degradation resulting in death or injury to listed species by significantly impairing essential behavioral patterns, such as breeding, feeding, or sheltering. Harass is defined by the USFWS as intentional or negligent actions that create the likelihood of injury to listed species to such an extent as to significantly disrupt normal behavior patterns that include, but are not limited to, breeding, feeding, or sheltering. Incidental take is defined as take that is incidental to, and not for the purpose of, the carrying out of an otherwise lawful activity. Under the terms of section 7(b)(4) and section 7(o)(2), incidental take is not prohibited under the Act, provided it is in compliance with the terms and conditions of this incidental take statement. 8.1 GRAY BAT MYGR have established a primary roost within the Action Area. The USFWS anticipates incidental take of gray bats may occur as a result of impacts to this roost despite efforts to avoid and minimize the probability for take. 59 All or some portion of these bats may temporarily or permanently abandon the roost due to disturbance from construction and tree clearing. Most of the take associated with impacts to this roost will be in the form of harm and harassment, but mortality of adult bats is possible. Noise and vibrations associated with construction near the roost may cause bats to be more active and expend more energy, leading to diminished fitness. If disruptive enough, noise and vibrations could also cause all or a portion of the bats to abandon the roost. If bats are aroused from torpor due to noise from the nearby activities in March and after October 15th, when food may be limited, they could deplete fat reserves, which could lead to decreased fitness and even death. The USFWS also anticipates incidental take of gray bats may occur as a result of impacts to foraging and commuting habitat from the construction and operation of Project Ranger. During construction, individual bats may be repelled from forage areas in the bridge footprints, along the French Broad River and tributaries, potentially reducing adult and juvenile fitness and affecting pup birth and health before they are able to fly and forage on their own. Additionally, more bats may be killed due to predation and car strikes if they are repelled from areas of active construction and forced to fly over the highway or through more open areas. Permanent changes in lighting may reduce suitable forage and commuting areas so that the number of bats utilizing the area decreases over the long term if bats avoid the elevated light levels. The number of gray bats using the French Broad River and its tributaries within and near the action area is estimated at 1900 to 2300 individuals. An unknown number of these will be affected by the construction activities (including: temporary lighting, noise, causeways, decrease in water quality, and loss of woody vegetation). Most of the take associated with impacts to commuting and foraging habitat will be in the form of harm and harassment, but some mortality of adult bats and newly-volant juveniles is possible. Additionally, some loss of recruitment is expected due to stress on pregnant and lactating females and subsequent loss of pups. This harm is not expected to cause mortality of all individuals within the Action Area, but could reduce fecundity and recruitment within the Action Area for the duration of project construction. This project could have long- term impacts on the bat population in this area. Data used to determine the number of gray bats in the Action Area is a conservative estimate, and gray bat populations are known to fluctuate seasonally and annually in a given area, therefore it is difficult to base the amount of incidental take on numbers of individual bats. Additionally, it is difficult to measure take of gray bats resulting from the action. Due to these reasons, the amount of incidental take will be monitored during construction over and adjacent to the river. The Applicant indicates that project construction will begin in August 2020 and take 14 months to complete. The amount of incidental take will be exceeded if 1) construction activities exceed 14 months, 2) if tree clearing limits exceed 84 total acres, or 3) if nightwork exceeds 22 nights during the MYGR maternity roost season. The population utilizing the FBR basin is estimated at 1,900 to 2,300, and the entire gray bat population is conservatively estimated at 4,358,263. This project will impact less than 0.001% of the gray bat population. Therefore, it is the opinion of the USFWS that the level of take is not likely to result in jeopardy to the gray bat. In addition to the subsequent measures listed in the Reasonable and Prudent Measures and Terms and Conditions sections of this Opinion, the measures listed in the Conservation Measures section of this opinion must be implemented for this determination to remain valid. 60 8.2 APPALACHIAN ELKTOE The USFWS anticipates incidental take of the Appalachian elktoe may occur as a result of project-mediated impacts to the French Broad River. Appalachian elktoe are present within the Action Area. During construction, individual mussels may be crushed, harmed by siltation or other water quality degradation, or dislocated because of physical changes in their habitat. The survey data is not sufficient to populate a robust population model, but in an effort to estimate potential take, the USFWS estimates an Appalachian elktoe density of 0.0005 mussels per square meter in the Action Area. Our knowledge of the density and distribution of Appalachian elktoe is based on a small number of documented occurrences. The survey data is not sufficient to populate a robust population model, but in an effort to estimate potential take, the USFWS applied a simple model incorporating survey effort and catch rates to estimate a baseline density for Appalachian elktoe in the Project Ranger Action Area. We estimated an experienced surveyor could reasonably cover 400 square meters in an hour of surveying. The mussels are not always at the surface, and due to difficulty seeing the small apertures in the substrate, surveyors are not likely to find every mussel. To compensate for this we estimated that a capture efficiency of 25% was reasonable based on previous experience with mussel survey techniques, i.e. the number of mussels found reflect 25% of the total mussels in a given area. Therefore, the model estimates an Appalachian elktoe density of 0.0005 mussels per square meter in the Project Ranger Action Area. This project proposes to directly affect around 30,500 square feet of habitat that will be covered by rock causeways and bridge footings. Based on the estimated density, we expect around two Appalachian elktoe to be in the area to be buried by bridge construction. Due to the extent and duration of this project, it is possible Appalachian elktoe in the Action Area will be affected by habitat degradation from sediment eroded from the project and from the degradation of channels receiving additional stormwater from the project. Applying the model density to the area of habitat in the Action Area returns an estimated population of 94 adult Appalachian elktoe. In order for the population to remain stable, recruitment in the action area needs to equal natural mortality in the population. Appalachian elktoe are estimated to live about 12 years with about 10 years of reproductive lifespan. That requires a recruitment rate of 0.10 annually, in this case approximately 1 new recruit per year that could be affected by project related effects. Due to the extent and duration of this project, it is possible Appalachian elktoe in the Action Area will be affected by habitat degradation from sediment eroded from the project and from the degradation of channels receiving additional stormwater from the project. Conservation measures outlined in the BA are intended to minimize effects due to sedimentation in the French Broad River. However, even under standard construction conditions, we expect Appalachian elktoe within the Action Area may be harmed by the presence of turbidity or settling of sediment in depositional portions of its habitat. We expect this effect to be non-lethal harm to adults that could result in temporarily reduced recruitment throughout the duration of the project. We do not anticipate that the effects of sediment pollution within the Action Area will reach a level that prevents recolonization of the Action Area after construction. 61 Therefore, in this Opinion, the USFWS has determined that this level of take is not likely to result in jeopardy to the Appalachian elktoe. In addition to the subsequent measures listed in the Reasonable and Prudent Measures and Terms and Conditions sections of this Opinion, the measures listed in the Conservation Measures section of this opinion must be implemented for this determination to remain valid. 8.3 REASONABLE AND PRUDENT MEASURES The USFWS believes the following reasonable and prudent measures are necessary and appropriate to minimize take of the gray bat and Appalachian elktoe. These non-discretionary measures include, but are not limited to, the commitments in the BA and the terms and conditions outlined in this Opinion. 1. Biltmore Farms will notify the Service and USACE of any project modifications, especially modifications that may exceed incidental take thresholds described in the Incidental Take Statement above (Section 8). 2. Biltmore Farms will install and monitor bat roost panels at the proposed bridge so that it may serve as an alternate roost for gray bat disturbed by Project Ranger. 3. Biltmore Farms will provide funding, not to exceed $127,000, to monitor gray bat activity at the primary roost within the action area. 4. Biltmore Farms will inspect abandoned structures located within the Action Area before demolition. 5. Biltmore Farms will provide reasonable site access to biologists for the purposes of monitoring bat activity during the construction duration for Project Ranger and NCDOT I-26 projects. 6. Biltmore Farms will minimize impacts to roosting bats to the extent possible for work occurring between March and mid-November. 7. Biltmore Farms will minimize permanent lighting of waterways to the extent possible, as well as permanent lighting at the undisclosed manufacturing facility. 8. Biltmore Farms will provide $15,000 in funding to appropriately respond to any project- mediated changes that may affect the health and recovery of the French Broad River population of Appalachian elktoe. 8.4 TERMS AND CONDITIONS In order for the exemptions from the take prohibitions of section 9(a)(1) of the ESA to apply, the Army Corps of Engineers must comply with the following terms and conditions, which implement the reasonable and prudent measures described previously, and outline required reporting and/or monitoring requirements. These terms and conditions are non-discretionary. As necessary and appropriate to fulfill this responsibility, the Army Corps of Engineers must require 62 any permittee, Contractor, or grantee to implement these Terms and Conditions through enforceable terms that are added to the permit, contract, or grant document. 1. Biltmore Farms will adhere to all measures listed in the Conservation Measures section of the BA and summarized in the proposed action section of this opinion. 2. Biltmore Farms will simultaneously notify USACE and USFWS of any permit modification requests. 3. USFWS will call for a meeting with Biltmore Farms at any time to evaluate and discuss erosion control effectiveness and identify corrective measures, as appropriate. 4. Bat roost panels will be designed and installed in coordination with the USFWS and NCDOT. Bat panel design must have explicit approval from NCDOT prior to installation. Biltmore Farms will monitor gray bat activity at the panels in coordination with USFWS until the NCDOT incorporates the bridge into the North Carolina state system of maintenance. 5. Biltmore Farms will monitor gray bat activity in the Action Area during the entire construction duration. The Applicant has committed to fund a monitoring effort up to $127,000 during project construction which they indicate will begin August 2020, and endure for 14 months. Biltmore Farms intends to employ biologists from Indiana State University (ISU) to accomplish this monitoring effort. At this time, the scope of this work and contract between the Applicant and ISU is under review, but must be finalized prior to construction. 6. To accomplish RPM 4, Biltmore Farms will inspect abandoned structures within the Action Area at least 30 days prior to demolition. Should bats be present within these structures, Biltmore Farms will forego demolition for 30 days to for removal of bats. 7. Biltmore Farms will provide monitoring access to their property for biologists from North Carolina Wildlife Resources Commission (NCWRC), ISU, NCDOT, NCDOT contractors (NV5 staff), and USFWS while construction activities for Project Ranger and nearby NCDOT I-26 projects are underway. It is understood that Project Ranger will be an active construction site for some of this duration and there may be restrictions to site access to accommodate safety requirements. Each agency or institution will provide a single point of contact to Biltmore Farms, and pre-register with notification to Lee Thomason III, lthomason@biltmorefarms.com. Biltmore Farms will provide gate access to biologists via their dispatch staff: 828.225.1581. 8. To accomplish RPM 8, Biltmore Farms will provide $15,000 to the North Carolina Nongame Aquatic Projects Fund to administer the French Broad River Conservation Plan. Funding will be held by NCWRC. A multi-agency/organization group of mussel experts, including USFWS staff will determine best use of fund expenditure. 63 9. MONITORING AND REPORTING REQUIREMENTS In order to monitor the impacts of incidental take, the USACE must report the progress of the proposed action and its impacts on the species to the USFWS. Biltmore Farms must notify the Service when the following construction activities begin and are completed: Tree clearing, construction of temporary causeways, blasting, bridge construction, shaft drilling, pile driving, and construction of the manufacturing facility. Biltmore Farms must notify the Service of any deviations to the construction timeline or project description as soon as those changes become foreseeable. Biltmore Farms must provide the Service with a description of the total acres of trees cleared, and total area of impervious surface installed post-construction so that we may amend the baseline conditions for future consultations. Biltmore Farms shall provide a final report to the Service that details findings of the proposed MYGR monitoring effort within three months of project completion. Biltmore Farms must notify the Service immediately if MYGR monitoring detects evidence of roost abandonment, or sudden/significant population declines. As necessary and appropriate to fulfill this responsibility, the USACE must require any permittee, contractor, or grantee to implement these Terms and Conditions through enforceable terms that are added to the permit, contract, or grant document. Such enforceable terms must include a requirement to immediately notify the USACE and USFWS if the amount or extent of incidental take specified in this Incidental Take Statement is exceeded during action implementation. Biltmore Farms and the USACE will provide notice to the USFWS at any point when the proposed project is modified in a manner not previously considered which may include, but is not limited to changes in proposed design, construction methods, construction timing and implementation of the Project. Biltmore Farms will provide notice to the USFWS and USACE when project construction begins, and at any point when construction delays are reasonably certain to occur, as construction duration affects gray bat monitoring requirements described above. 10. REINITIATION NOTICE Formal consultation for Project Ranger is concluded. All work should stop and the USFWS should be contacted immediately to reinitiate consultation if: 1. the amount or extent of incidental take is exceeded. That is, if construction activities cannot be completed within 14 months; 2. new information reveals that the Action may affect listed species or designated critical habitat in a manner or to an extent not considered in this BO; 3. the Action is modified in a manner that causes effects to listed species or designated critical habitat not considered in this BO; or 4. a new species is listed or critical habitat designated that the action may affect. 64 11. CONSERVATION RECOMMENDATIONS We offer the following recommendations in the interest of protecting natural resources, many of which may benefit rare or imperiled species known to occur in the vicinity of Project Ranger: Bog Turtle Bog turtle occurs in the project vicinity and suitable habitats for this species may occur within or adjacent to the action area. While bog turtle is not subject to consultation under section 7 of the Act, we request that the Applicant install silt fencing along the access roads and disturbance areas to ensure that silt, fine sediment, and construction equipment does not go into wetlands. Contractors should be made aware of the potential for encountering this animal traveling over construction access roads and make every effort to avoid collisions. We request that any bog turtle encounters be reported to this office. Erosion and Sediment Control Measures to control sediment and erosion should be installed before any ground-disturbing activities occur. Grading and backfilling should be minimized, and existing native vegetation should be retained (if possible) to maintain riparian cover for fish and wildlife. Disturbed areas should be revegetated with native vegetation as soon as the project is completed. Ground disturbance should be limited to what will be stabilized quickly, preferably by the end of the workday. Natural fiber matting (coir) should be used for erosion control as synthetic netting can trap animals and persist in the environment beyond its intended purpose. Low Impact Development The Service is concerned about the potential stormwater-mediated impacts to receiving streams and wetlands. Detention structures should be designed to allow for the slow discharge of storm water, attenuating the potential adverse effects of storm-water surges; thermal spikes; and sediment, nutrient, and chemical discharges. Since the purpose of storm-water-control is to protect streams and wetlands, no storm-water-control measures or best management practices should be installed within any stream (perennial or intermittent) or wetland. We recommend that retention ponds be located at least 750 feet from small wetlands to minimize hydrologic disturbance and ecological function. We also recommend that consideration be given to the use of pervious materials (i.e., pervious concrete, interlocking/open paving blocks, etc.) for the construction of roads, driveways, sidewalks, etc. Pervious surfaces minimize changes to the hydrology of the watershed and can be used to facilitate groundwater recharge. Pervious materials are also less likely to absorb and store heat and allow the cooler soil below to cool the pavement. Additionally, pervious concrete requires less maintenance and is less susceptible to freeze/thaw cracking due to large voids within the concrete. Pollinator Habitat Pollinators, such as most bees, some birds and bats, or other insects, including moths and butterflies, play a crucial role in the reproduction of flowering plants and in the production of 65 most fruits and vegetables. Declines in wild pollinators are a result of loss, degradation, fragmentation of habitat, and disease. The rusty-patched bumble bee (Bombus affinis) historically occurred in North Carolina’s Mountain and Piedmont provinces. Although not required, we encourage Biltmore Farms to consider our recommendations below which may benefit the rusty-patched bumble bee and other pollinators. Moreover, the creation and maintenance of pollinator habitats at this site may increase the value of the project for the community and help reduce the spread of invasive exotic plants. Please consider the following: 1. Sow native seed mixes in disturbed areas or in designated pollinator areas with plants that bloom throughout the entire growing season. 2. Taller growing pollinator plant species should be planted around the periphery of the site and anywhere on the site where mowing can be restricted during the summer months. Taller plants, left un-mowed during the summer, would provide benefits to pollinators, habitat to ground nesting/feeding birds, and cover for small mammals. 3. Low growing/groundcover native species should be planted in areas that need to be maintained. This would provide benefits to pollinators while also minimizing the amount of maintenance such as mowing and herbicide treatment. Milk weed species are an important host plant for monarch butterflies. 4. Avoid mowing of flowering plants. Designated pollinator areas show be mow only 50% of the plant height, but no lower than 8 inches. 5. Avoid mowing outside the active season for rusty-patched bumble bee and other pollinators (April 15 – October 15). 6. Leave slash piles, mulch piles, or loose dirt piles along woodland edges. These areas provide nesting habitats and/or nest materials for some pollinators. 7. Avoid the use of pesticides and specifically neonicotinoids. 8. Additional information regarding plant species, seed mixes, site preparation, and pollinator habitat requirements can be provided upon request. 12. LITERATURE CITED Adams, R. A. 2010.
