Dear Mr. Lund:

SECRETARY
I have enclosed a straight-line diagram with erosion control plan, a PCN application for
NWP #14, and a location map relative to the proposed project on SR 1285, West
Ashworth Road, McDowell County, NC.
W. Ashworth Road is currently a 14-16 feet wide gravel road. Division of Highways
plans to pave the road 18 feet wide and increase the typical section. Grading will be
light.
We propose to extend one existing culvert on an UT to North Muddy Creek. Total
culvert extension will be 20 linear feet. Existing channel morphology will be maintained
upstream and downstream of the culvert. The culvert will be placed below existing
streambed elevation. Riparian vegetation will be reestablished along disturbed areas
associated with the culvert extensions. Stormwater will be diverted through grass-lined
ditches or vegetated buffers prior to entering streams.
No significant effect on federally listed species (threatened or endangered) or their
habitats is anticipated.
By copy of this letter, we request Owen Anderson, North Carolina Wildlife Resources
Commission Mountain Region Coordinator, to comment directly to the Corps and the
Area Roadside Environmental Engineer concerning the permit request.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 5 of 8
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strrngide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

EROSION CONTROL PLAN SHEET
Generally, the order of installation of the erosion control measures will be as
follows:
Temporary silt basins shall be installed before clearing and
grubbing begins.
Silt fences and temporary silt ditches shall be installed after
clearing and before grading.
Temporary stone ditch checks shall be installed as soon as
ditch line is established.
Pipe outlet and inlet protection will be done as soon as the
pipe is installed.
Seeding and other permanent erosion control measures are
to be implemented as soon as practical.
Temporary rock silt checks (type B) will be spaced as required
by percent of grade as described on page VI-16 in the Erosion
And Sedimentation Guidelines.
No. 5 stone, or equivalent, will be used in conjunction with
temporary rock silt check Type-B in locations where water is
leaving the project or entering a pipe.
Silt basin size is 9'x3'x2' for 75 feet of disturbed ditch line unless otherwise
noted.
Silt basin (Type B) are designed for 1200 cubic feet per acre every storm event
and cleaned out when half full.
Per permit conditions for Corps of Engineers and the Wildlife Resources
Commission, all pipes in streams must be buried 12" below streambed
elevation.
Sheet 5 of 11
PIPE INSTALLATION NOTES
1) Install erosion control devices. In streams, where necessary, rock silt
. screen will be used.
2) Remove material and existing pipe while limiting, as much as possible,
material and sediment from entering the stream and/or escaping from project.
3) Prepare pipe foundation while again taking care to limit, as much as possible
material and sediment from entering the stream and/or escaping from project.
Where possible, new grade will be below existing streambed. If needed,
bedding material will be clean stone.
4) Place the new pipe and compact backfill.
5) Install slope protection on outlet and inlet ends of pipe. Also complete
installation of erosion control measures and perform maintenance as needed
on existing measures.
6) Establish permanent vegetation as soon as possible.
