SUBJECT: Duke Energy — Horseshoe — Capps 44 kV Line Rebuild Project
Wetlands in the upper French Broad River Basin, Henderson County
Dear Mr. Brown:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) reviewed an
application for impacts to wetlands associated with the replacement of transmission wiring and
structures along a 2.5 -mile maintained right-of-way in Henderson County. 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).
The project will involve permanent impacts to 0.01 acre of wetland and temporary impacts to
0.32 acre of wetland associated with the installation of new poles. Temporary impacts would be
due to the placement of temporary work matting; after work is complete, the matting will be
removed.
Th project may also involve the replacement of existing culverts with culverts of the same size
and material. Streambanks will be sloped, matted, and seeded with native vegetation. The
project should not impact trout and a trout moratorium does not need to be observed.
According to Will Metcalf with Duke Energy, any woody vegetation within 50 feet of a stream or
wetland will be hand cleared. Woody vegetation would be cut to no less than 6 -inches above
ground.
We offer the following recommendations to minimize impacts to fish and wildlife resources:
1. 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 near

wetlands and streams should be seeded, mulched and matted as soon as possible, preferably
at the end of each work day.
2. Any erosion control matting used near streams and wetlands should be free of plastic or
nylon 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. We recommend that woody vegetation within riparian areas be cut to allow shrubs and trees
of a greater height to remain. Shrubs and trees of even 4-8 feet in height can provide some
stream shading, bank stability, and wildlife habitat.
4. A native wetland seed mix should be planted in impacted wetland areas.
Thank you for the opportunity to review and comment on this project. Please contact me at
