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 trout reproduction should not be impacted by project activities, and a trout moratorium is not needed. However, the Spring Creek is part of the Lower French Broad River Aquatic Habitat, a NCNHP natural area rated Exceptional due to the richness and importance of rare species it supports. These species include the Logperch (Percina caprodes, NC Threatened), Eastern Hellbender [Cryptobranchus alleganiensis, US Federal Species of Concern (FSC), NC Special Concern (SC)], Freshwater Drum (Aplodinotus grunniens, NC SC), Banded Sculpin (Cottus carolinae, NC SC), Mountain Madtom (Noturus eleutherus, NC SC), Olive Darter (Percina squamata, NC SC), Eastern Spiny Softshell (Apalone spinifera, NC SC), Ohio Lamprey (Icthyomyzon bdellium, NC SC), Mountain Brook Lamprey (Lethenteron appendix, NC SC), Blotched Chub [Erimystax insignis, NC Significantly Rare (SR)], Highland Shiner (Notropis micropteryx, NC SR), and French Broad River Crayfish (Cambarus reburrus, NC SR). Excellent sediment and erosion control are necessary to minimize impacts to this stream and the rare species it supports. The application proposes to replace a malfunctioning sewer and manholes along Spring Creek. Two areas of problematic erosion totaling 62 ft would be stabilized with a block retaining wall. Another 426 ft of stream would be impacted by installation of a coffer dam (sand bags and riprap) to isolate the stream from the work for the sewer line installation.

Work would take approximately 45 days. Instead of stabilizing the stream banks with riprap and seed, we strongly recommend planting native shrubs and trees instead. Even a narrow line of woody vegetation can afford wildlife benefits, bank stabilization, and stream shading. 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. Disturbed areas should be stabilized at the end of each work day. 2. Instead of riprap, we recommend stabilizing stream banks with live stakes and containerized native trees and shrubs. 3. 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.
