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). Project activities should not impact wild trout and do not need to be avoided during the trout moratorium. However, the North Fork New River is recognized by the NC Natural Heritage Program as the North Fork New River Aquatic Habitat, rated Exceptional for the richness of rare species it contains. Rare and listed species found in the river in the vicinity of the project include Eastern Hellbender (Cryptobranchus alleganiensis, US Federal Species of Concern, NC Special Concern), Seep Mudalia (Leptoxis dilatata, NC SC), Kanawha Minnow (Phenacobius teretulus, NC SC), Kanawha Darter [Etheostoma kanawhae, NC Significantly Rare (SR)], and Tongue-tied Minnow (Exoglossum laurae, NC SR). Due to the sensitivity of these species to fine sediments, it is essential that excellent erosion and sediment control be maintained during the project. The application proposes to stabilize an eroding reach of bank on the North Fork New River through sloping the bank, planting native woody and herbaceous vegetation, and installing two in -stream rock vanes. Most work will be done from the bank, but some instream access may be necessary for proper installation of the rock vane. We offer the following recommendations to minimize impacts to the aquatic community: 1. In -channel work should be accomplished as quickly as possible and vigilance used in sediment and erosion control during site preparation, construction, and clean up.

Fork New R, Ashe County areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of each work day. 2. Any erosion control matting used should be free of nylon or plastic mesh, as this type of mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years. 3. Work should be performed during low flows. For the rock vane installation, we recommend diverting flows around the work area especially at the bank tie in location to reduce the risk of fine sediment liberation and loss. 4. Depending on the construction timeframe, NCWRC staff may come out to survey the site before project construction for rare animals. We ask that the project manager coordinate with Andrea Leslie (andrea.leslie@ncwildlife.org) and Lori Williams (lori.williams@ncwildlife.org to ensure access to the site. 5. Shelter rocks potentially used by hellbenders should be left undisturbed during construction activities. Shelter rocks are typically large flat rocks at least a foot in diameter. If animals are disturbed during construction, they should be captured in a bucket and moved away from the area of disturbance. Please notify Lori Williams (lori.williams@ncwildlife.org) if hellbenders are found. 6. To increase habitat diversity, we recommend incorporating stable woody debris into the project design. 7. We recommend that a woody buffer as wide as possible (we recommend at least 30 feet) be planted on the stream as infrastructure allows in order to ensure project success. A wide forested buffer can ensure greater bank stability, filter overland pollutants, and provide habitat for birds and other wildlife.
