FROM: Marla Chambers, Western NCDOT Coordinator t �%ict-prz�Zk,,
Habitat Conservation Program, NCWRC
SUBJECT: Review of NCDOT's application for Section 404 and 401 permits to replace a
culvert on NC 106 in Turtle Pond Creek, Macon County, North Carolina.
The North Carolina Department of Transportation has submitted an application to obtain a
Section 404 Permit from the U.S. Army Corps of Engineers and a 401 Water Quality
Certification from the NC Division of Water Resources. Staff biologists with the North Carolina
Wildlife Resources Commission have reviewed the information provided. These comments are
provided in accordance with the provisions of the state and federal Environmental Policy Acts
(G.S. 113A-lthrough 113-10; 1 NCAC 25 and 42 U.S.C. 4332(2)(c), respectively), the Clean
Water Act of 1977 (33 U.S.C. 466 et seq.), the Endangered Species Act (16 U. S. C. 1531-1543;
87 Stat 884), and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C.
661-667d), as applicable.
The NCDOT proposes to replace a culvert on NC 106 in Turtle Pond Creek with two welded
steel pipes (48" H x 75'L). The pipes will be buried 20% of their diameter on a 1.5% slope.
Permanent impacts include 75 linear feet of stream due to the culvert, 301f of streambank
impacts from bank stabilization, and 0.02 acres of wetland impacts due to a work pad.
Temporary impacts total 38 if for stream dewatering. Turtle Pond Creek supports Brook and
Rainbow trout downstream of the project therefore a moratorium prohibiting in -stream work and
land disturbance within the 25-foot trout buffer should apply from October 15 to April 15 to
protect the egg and fry stages of trout. Sediment and erosion control should adhere to the Design
Standards in Sensitive Watersheds and be strictly maintained.

NCWRC does not object to the issuance of the Section 404 and 401 permits provided that the
following conditions are implemented:
1. In -stream work and land disturbance within the 25-foot wide buffer zone are prohibited
during the trout spawning seasons of October 15 through April 15 to protect the egg and
fry stages of trout.
2. Sediment and erosion control measures shall adhere to the Design Standards in Sensitive
Watersheds and be strictly maintained until project completion.
3. Herbaceous vegetation shall be planted on all bare soil as soon as possible following the
completion of permanent or temporary ground disturbing activities to provide appropriate
long-term erosion control.
4. Tall fescue and straw mulch shall not be used in riparian areas. We encourage NCDOT
to utilize onsite vegetation and materials for bank stabilization when practicable. Erosion
control matting shall be used on steep slopes and for establishing permanent vegetation in
riparian areas. The matting shall be well anchored with staples or wooden stakes and,
whenever possible, include live stakes of native trees. Matting in riparian areas should
not contain plastic mesh, which can entangle and trap small animals.
5. Stormwater should be directed to buffer areas or retention basins and should not be
routed directly into the waterway.
6. The natural dimension, pattern, and profile of the waterway above and below the
crossings should not be modified by widening the channel or changing the depth of the
waterway.
7. Removal of vegetation in riparian areas should be minimized. Native trees and shrubs
should be planted along the banks, as appropriate to the setting, to reestablish the riparian
zone and to provide long-term erosion control.
Grading and backfilling should be minimized, and tree and shrub growth should be
retained if possible to ensure long term availability of shoreline cover for fish and
wildlife. Backfill materials should be obtained from upland sites.
9. Where practicable, riprap placed for bank stabilization should be limited to the banks
below the high water mark, and vegetation should be used for stabilization above the high
water elevation.
10. If concrete will be used during construction, work must be accomplished so that wet
(uncured) concrete does not contact surface waters. This will lessen the chance of
altering the water chemistry and causing a fish kill.
11. Discharging hydroseeding mixtures and washing out hydroseeders and other equipment
in or adjacent to surface waters is prohibited.

12. Heavy equipment should be operated from the bank rather than in the channel whenever
possible in order to minimize sedimentation and reduce the likelihood of introducing
other pollutants into the waterway. All mechanized equipment operated near surface
waters should be inspected and maintained regularly to prevent contamination of surface
waters from fuels, lubricants, hydraulic fluids or other toxic materials.
