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). Wild Rainbow Trout are found in the project vicinity, and in -stream activities should be avoided during the trout moratorium of January 1 to April 15. In addition, Younce Creek is part of the Little Tennessee River (Lower) Aquatic Habitat, a NC Natural Heritage Program natural area rated Exceptional due to the richness and importance of aquatic species it supports. In the vicinity of the project, these species include Sicklefin Redhorse (Moxostoma sp., NC Threatened), Eastern Hellbender [Cryptobranchus alleganiensis, US Federal Species of Concern (FSC), NC Special Concern (SC)], Little Tennessee Crayfish (Cambarus georgiae, US FSC, NC SC), and Smoky Dace (Clinostomus sp., NC SC). Trout and these rare species are especially sensitive to excess sediment, and proper sediment and erosion control is essential to protect this aquatic community. The application proposes to restore an unstable reach of that is threatening a parking lot. The stream will be stabilized by shifting the stream channel away from the parking lot, grading banks, planting a native riparian buffer, and installing j-hooks and constructed riffles. Plans note that work will be done at low flows or in the dry as much as possible. A 20-ft buffer will be planted where infrastructure allows.

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. Plans note that the site will be made storm -ready by the end of each work week. Instead, disturbed areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of each workday. 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. Flows should be pumped around in -stream work areas, or at the very least, diverted around work areas. 4. In -stream work should be avoided between January 1 and April 15 to minimize impacts to trout reproduction. Thank you for the opportunity to review and comment on this project.
