SUBJECT: Rob Dolsak 404 Permit Application
Shoreline stabilization -Lake Glenville
Jackson County DWQ No. 07-1880
Dear Mrs. Miller and Mr. McMillan:
Mr. Rob Dolsak requested a 404 Permit from the U.S. Army Corps of Engineers. Comments from the
North Carolina Wildlife Resources Commission (Commission) are provided under provisions of the
Clean Water Act of 1977 (33 U.S.C. 466 et seq.) and the Fish and Wildlife Coordination Act (48 Stat.
401, as amended; 16 U.S.C. 661-667d).
The project involves placement of rip rap along 164 feet of Lake Glenville shoreline.
The Commission is concerned about the adverse effects of some shoreline stabilization on aquatic and
lakeshore habitats. Therefore, the Commission recommends conditioning the permit as follows to help
conserve fish and wildlife habitat:
1. The nroiect addresses an active and appreciable shoreline erosion problem• relatively stable
shorelines are not altered.
2. The project complies with Duke Energy's Shoreline Management Guidelines and receives approval
from Duke Energy Lake Management.
3. If practical, the stabilization work is completed in a dry work area while the lake is drawn-down.
4. Adequate sedimentation and erosion control measures are used to minimize the loss of disturbed soils
into the lake.
5. The lakebed is not excavated or otherwise disturbed except where necessary to bed rock in the
lakebed. The shoreline and the lakebed outside of the stabilization area is not disturbed for access or
staging of materials.
6. Anv lame woodv debris in the lakebed and in the oath of the stahilization remains nr is renlaceri anrt
secured to the shoreline at the completion of the project. Stumps, rocks or woody debris
lakebed are not removed.

7. Filter fabric is installed behind the rock to minimize wash-out.
8. The rock used is large quarry (class II or larger) or similar angular stone that is free of sediment and
other contaminants.
9. If a vertical wall is part of the stabilization, additional rock is placed at the base or toe of the lakeward
side of the wall to prevent undercutting and to enhance fish habitat.
10. The spaces between the rocks is not filled with concrete or other types of grout, but left open to allow
native plants to grow and to provide cover for fish and wildlife. Uncured concrete is toxic to fish and
other aquatic life.
11. If temporary access across the shoreline buffer is granted, the vegetation is cut off at the ground and
the stumps and roots left intact to sprout or the area is replanted with native vegetation. Areas along
the shoreline without woody vegetation or where it must be removed are planted with native trees
(e.g., hemlock, tulip poplar, and sycamore) and shrubs (e.g., silky dogwood, rhododendron, mountain
laurel or dog hobble).
12. The height of rock stabilization is no more than a few inches above the normal pool elevation.
However, a greater height is acceptable, as determined by a Duke Energy representative, if the
erosion extends above the normal pool elevation. In these cases, backfilling should be minimized
(e.g. rock placed as close to eroded shoreline as possible) and mimic the natural shoreline slope. If a
stacked wall is used, the rock should be set slightly lakeward to minimize disturbance of vegetation
on the bank. Voids around trees with exposed roots should be backfilled with soil.
Thank you for the opportunity to review and comment on this project. Pending availability of field staff,
the Commission may inspect the work site during or after construction. ff there are any questions
regarding these comments, please contact me at 828/452-2546 extension 24.
Sincerely,
~~.
