APPROVAL of 401 Water Quality Certification
Mr. W.O. Atkins
NC DOT
Elkin District Office
PO Box 558
Elkin NC 28621
Dear Mr. Atkins:
You have our approval, in accordance with the attached conditions, to place fill material in 0.15 acres of wetlands or
waters for the purpose of maintaining SR 1141, as you described in your application dated January 15, 1998. After
reviewing your application, we have decided that this fill is covered by General Water Quality Certification Number 3127.
This Certification allows you to use Nationwide Permit Number 3 when it is issued by the Corps of Engineers. In
addition, you should get any other federal, state or local permits before you go ahead with your project including (but not
limited to) Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations.
Also this approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the
General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If total wetland fills for this project
(now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h). For this approval to be valid, you must follow the conditions listed in the attached certification.
If you do not accept my of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 davs of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh,
N.C. 27611-7447. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you
have any questions, please telephone John Dorney at 919-733-1786.
Sincerely,
0.ton Howard, Jr. P. .

Review of an application by NCDOT to grade, drain, base and Pave SR 1141,
(Meadowfork Road) from NC 18 to SR 1193, Alleghany County.
The North Carolina Department of Transportation (NCDOT) is requesting a letter of
concurrence from the North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404
permit from the U.S. Army Corps of" Engineers. The NCWRC has reviewed information
provided by the applicant, and tield biologists on our staff are familiar with habitat values of the
project area. 'T'hese continents are provided in accordance with 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).
'T'ile project will impact tributaries to Meadow Fork and the headwaters of the Little
River. Streams to be impacted are to small to contain trout, however, both streams downstream
of the project site contain wild brook and rainbow trout. Meadow Fork immediately below the
junction of SR 1141 and SR 1 193 is Designated Public Mountain Trout Water, however, no wild
trout are found in this upper section of Meadow Fork due to a fish stop falls located further
downstream (NCWRC data, 11/93). On the Little River drainage, wild rainbow trout are found
below the.j unction of SR 1 141 and NC 18.
Pipes will be replaced or extended at Stations 57+80, 58+20 and 62+20 on the Meadow
Fork drainage. Encroachment of the trout stream buffer zone will occur at stations 21+00 to
25+50 on the Little River drainage and Stations 67+00 to 69+35 on the Meadow Fork drainage.
We are pleased that NC DOT has adjusted the road alignment to avoid working in the stream and
trout stream buffer zone as much as possible. Paving of this road, along with proper construction
and seeding of ditch lines should help reduce off site sedimentation currently coming from the
existing gravel road.
We have no objection to the project as proposed provided the following conditions are
implemented:
1. Instream work and land disturbance within the 25-foot wide buffer zone is prohibited during
the trout spawning season of October 15 through April 1 to protect the egg and fry stages of
trout from off site sedimentation.
2. Stringent erosion control measures should be installed where soil is disturbed and maintained
until project completion.
Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15
days of ground disturbing activities to provide long-term erosion control. We prefer a `seed-
as-you-go" strategy rather than allowing a large area of exposed earth to remain bare. If
seeding is done after 1 October 1997, then the NCDOT should return after 1 April 1998 to
reseed any bare areas if necessary.
Thank you for the opportunity to review and comment on this project. If you have any
questions regarding these comments, please contact me at 336/366-2982.

Re: Grade, Drain, Base, and Pave SRI 141 (Meadowfork Road) from N. C. 18
to SRI 193 in Alleghany County, N. C.
Dear Mr. Jolly:
The North Carolina Department of Transportation, District I Maintenance plans
to grade this road primarily along the existing alignment in the 1998 - 1999
Fiscal Year. We will be replacing/extending existing pipes which involve live
streams at Station 57+80, 58+20, and 62+20. We will also be extending or
replacing various other pipe culverts throughout the project which do not involve
live streams. We will be encroaching upon the 25' trout stream buffer as follows:
1) Lt of Station 21+00+- to Station 25+50+- and 2) Lt of Station 67+00+- to
Station 69+35. We have made minor shifts in the alignment in these areas to
avoid relocating the stream. Also, we will narrow the shoulder as necessary to
avoid working in the stream. This work is to improve the typical section and the
safety of the road.
We are requesting a 404 Nationwide Permit (#3 Maintenance) from your agency.
I am sending a straight line sketch with the proposed erosion control, stream,
and cross sections of the affected areas. In addition, I am sending a typical
section of the road, general notes on erosion control and a marked map.
By copy of this letter I am asking Mr. Joe Mickey, Mountain Region Coordinator
of the North Carolina Wildlife Resources Commission to comment directly to you
concerning the 404 Nationwide Permit request.

A request will be made on this project for a Temporary Encroachment in the
Trout Water Buffer Zone of tributaries to Meadowfork Creek, a designated
mountain trout water, and I am asking Mr. Mickey to comment directly to me
concerning the Trout Water Buffer Zone Encroachment.
Also, by copy of this letter, I am requesting authorization to proceed under
Section 401 of the Clean Water Act from the Division of Environmental
Management.
We would plan to begin construction in the summer of 1998. If further
information is required, please let me know. Your early review and
consideration of this request will be greatly appreciated.

The proposed right of way is staked 50' wide, 25' on each side of the centerline.
There is an existing 100' x 100' sight distance on the right and left of intersection
NC 18 and SR 1141. Project ends at intersection of SR 1191 and SR 1141 at
station 70+11.
Your efforts in obtaining this right of way should be charged to W.O. 6.702267.
This project is to be constructed during the 1998-1999 program.
Your further handling and notifying of this office will be greatly appreciated.

Silt fences and temporary silt ditches shall he
installed after clearing and before grading.
Temporary stone ditch checks shall he installed as
