In addition, temporary impacts to 40 ft of stream for pump around diversions are proposed. 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). There are wild Brown Trout in the project vicinity, and in -stream activities should be avoided between October 15 and April 15 to minimize impacts to trout reproduction. Effective erosion and sediment control on this project is essential to protect this species. The application proposes to restore an eroding reach of Linville Creek and a tributary with a dense set of rock and/or log cross vanes and j-hooks and constructed riffles. Banks will be graded, and a native riparian buffer of 10-25 ft will be planted on the stream banks. Work will be done in the dry. 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 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.

In -stream activities should be avoided between October 15 and April 15 to minimize impacts to wild trout reproduction. 4. We recommend softening the project design, using fewer structures, more wood and less rock, and making the distribution of structures less regular. 5. The planted buffer is proposed to be 10-25 ft in width. A buffer of 10 ft will do little to maintain bank stability over time. We strongly recommend that a woody buffer of at least 30 feet be planted on both sides of 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. 6. Eastern Hemlock and Green Ash are included in the planting plan; we recommend removing these species due to pests that are causing widespread mortality of these species and replacing them with additional species. In addition, Black Gum is included, which is an upland species — it is appropriate if planted in an upland setting only. Thank you for the opportunity to review and comment on this project.
