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). This project should not affect trout and the activities do not need to be avoided during the trout spawning moratorium. However, the project is adjacent and just upstream of the Little River, which is part of the Little River Aquatic Habitat, a Natural Heritage Program natural area rated as Exceptional due to the richness and ecological importance of the species it supports. Species in the vicinity of the project include Appalachian Elktoe [Alasmidonta raveneliana, US Endangered (E), NC E], Longsolid [Fusconaia subrotunda, US Federal Species of Concern (FSC), NC E], Creeper (Strophitus undulatus, NC Threatened), Common Mudpuppy [Necturus maculosus, NC Special Concern (SC)], and French Broad River Crayfish (Cambarus reburrus, NC Significantly Rare). As these species is sensitive to excess sedimentation, it is especially important to use excellent erosion and sediment control on site to minimize impacts to this species. The project would replace a length of gas line that is exposed. The new line would be buried in the stream via trench cut, and the work would be done by pumping flows around the work area. The work area appears to be approximately 150 ft wide, narrowing to approximately 100 ft at the stream. As the riparian buffer on the stream will be disturbed, we recommend restoring the disturbed buffer with a mix of native trees, shrubs, and herbaceous vegetation.

Be vigilant with sediment and erosion control during site staging, construction, and cleanup. Due to the presence of Appalachian Elktoe, 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. 2. Any erosion control matting used should be free of nylon or plastic mesh, as this netting frequently entangles wildlife and is slow to degrade resulting in a hazard that may last for years. 3. Restore the buffer that will be disturbed on the UT to the Little River with native trees, shrubs, and herbaceous vegetation. Please see the attached NC State University's riparian restoration guide, which includes a plant list for mountain sites. Thank you for the opportunity to review and comment on this project. Please contact meat (828) 400-4223 if you have any questions about these comments or need further assistance.
