APPROVAL of 401 Water Quality Certification and ADDITIONAL CONDITIONS
Mr. Michael A. Pettyjohn, P.E., District Engineer
North Carolina Department of Transportation
P.O. Box 558
Elkin, NC, 28621
Dear Mr. Pettyjohn:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
material in 0.009 acres of wetlands and 100 linear feet of streams for the purpose of paving SR 1131A
(Waterfalls Road) from SR 1130 to 1.61 miles west, near Sparta. The project should be constructed in
accordance with your application dated 1 March 2000 (received 23 March 2000). After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification Number 3103.
This certification corresponds to the Nationwide Permit Number 14 issued by the Corps of Engineers. In
addition, you should acquire any other federal, state or local permits before you proceed with your project
including (but net limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed
regulations. This approval will expire with the accompanying 404 permit, unless otherwise specified in the
Water Quality Certification. The following additional conditions will be required:
1. The double culvert shall be installed in such a manner that the original stream profile is not altered (i.e.
the depth of the channel should not be reduced by a widening of the stream bed).
2. The 100 LF of culvert on the intermittent channel shall be installed at least one foot below the channel
bed so as to allow passage of water and aquatic life.
3. All work shall be performed during low flow conditions.
4. Care must be utilized such that live (wet) concrete does not enter the stream channel.
5. The presence of equipment in the channels must be minimized.
This approval is valid solely for the purpose and design described in your application (unless modified
below). Should your project change, you must notify the DWQ and submit a new application. If the
property is sold, the new owner must be given a copy of this Certification and approval letter, and is thereby
- responsible for complying with all the conditions. If total wetland fills for this project (now or in the future)
exceed one acre, or if total impacts to streams (now or in the future) exceed 150 linear feet, compensatory
mitigation may be required as described in 15A NCAC 211.0506 (h) (6) and (7). For this approval to
remain valid, you must adhere to the conditions listed in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory
hearing. You must act within 60 days of the date that you receive this letter. To ask for a
hearing, send a written petition that 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.

Re: SR1131A (Waterfalls Road) Alleghany County, NC
Dear Mr. Galamb:
Attached are plans for the paving of this road in Alleghany County. Since we are planning to
install two pipes for stream crossings, which require a Corps of Engineer Permit Wd. are
asking for your review and issuance of a 401 Certification for this work. From the plans, you
will see that we plan to install 100 LF of new culvert in stream left of station 27+00+- to station
28+00 in order to improve the typical section of the roadway without relocating the stream
channel. Also, we plan to.install a double line of 87°x63" BCCS pipe with a concrete headwall
at station 45+65. This pipe is to replace a narrow existing bridge.
Your review of these plans and any suggestions which might aide us in accomplishing this
work with minimum environmental impact will be appreciated.
I look forward to hearing from you.
Yours very truly,
A 4.1 aiiol--

Dear Mr. Jolly:
The. North Carolina Department of Transportation, Division 11, District I Maintenance
plans to revise the above project as permitted. This revision was made necessary due
to condition of the existing bridge #257 in Alleghany County, at Sta. 45+65, that will be .
replaced with a double line of 87" x 63" BCCS Pipe with a concrete headwall at the inlet
end and rip-rap at the outlet end.
I - am sending a sketch showing the proposed revisions.
If further information is required, please let me know.
Your early review and consideration will be greatly appreciated.

Re: Grade, Drain, Base, and Pave SR1131 A (Waterfall Road) from
SR1130 to 1.61 Miles 1.61 Miles in Alleghany County, N. C.
Dear Mr. Jolly:
hl
The North Carolina Department of Transportation, District I Maintenance plans
to grade this road primarily along the existing alignment in the 1999 - 2000
Fiscal Year. We will be replacing/extending existing pipes which involve live
streams at Station 26+75 - 50' of 24" pipe which results in an additional 20' of
impact and at Station 35+85 - 60' of 72" pipe which results in an additional 28'
of impact to the stream. We will also be replacing/extending various other pipes
throughout the project which do not involve live streams. We will be filling
approximately .009 acres of wetland right of station 26+50. We will be
encroaching upon the 25' trout stream buffer as follows: 1) Install gabion
baskets as a retaining wall to lessen the impact on the stream right of Station
22+55+- and right of Station 23+90+- to Station 24+13+-. These gabion baskets
will result in an additional 28' of impact to the stream. 2) Install 100' of new
culvert in the stream left of Station 27+00+- to Station 28+00+- in order to
improve the typical section of the roadway without relocating the channel. 3)
Right of Station 35+90+- to Station 37+05+- construction embankment and 4)
Right -of Station 46+00+- to Station 47+50+- construction of embankment. 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. Ron Linville, 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 Little River, a designated mountain
trout water, and I am asking Mr. Linville to comment directly to me concerning
the Trout Water Buffer Zone Encroachment.
We would plan to begin construction this spring. If further information is .
required, please let me know. Your early review and consideration-of this _
request will be greatly appreciated

- FROSTON CONTROL PLAN SHEET
Silt Basin Type B's will'be constructed to the dimension.of
six feet by three feet by three feet unless otherwise noted
on the plans.
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.
