APPROVAL of 401 Water Quality Certification
Mr. C.R. Styles
N.C. DOT
P.O. Drawer 250
Bryson City, N.C. 28713
Dear Mr. Styles:
You have our approval, in accordance with the attached conditions, to place fill material in 0.0033 acres of wetlands or
waters for the purpose of improving SR 1621, as you described in your application dated 1 April 1999. After reviewing
your application, we have decided that this fill is covered by General Water Quality Certification Number 3108. This
Certification allows you to use Nationwide Permit Number 26 when the Corps of Engineers issues it. 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 send us 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 conditions. 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. This
approval shall expire when the corresponding Nationwide Permit expires or as otherwise provided in the General
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 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 Domey at 919-733-1786.
Sincerely,
Stevens

Dear Mr. Galamb:
,
E. NORRIS TOLSON
SECRETARY
The North Carolina Department of Transportation is proposing to grade, drain, base
and pave primarily along the existing roadway of SR 1621, West Cove Road in Haywood
County. In order to construct this project in accordance with our current secondary road
standards and due to the addition of one (1) pipe culvert, and the replacement and/or extension
of five (5) pipe culvert in several unnamed tributaries of West Cove Branch (DEM Class C), we
are requesting authorization under Section 401 of the Clean Water Act.
am sending a straight-line diagram with our proposed erosion control and
construction limits at various sites along this project. In addition, a typical section of the road,
drawings for the pipe addition, and the pipe replacements and/or extensions in the unnamed
tributaries of West Cove Branch, general notes and standards on erosion control measures,
and a marked County Map are enclosed. We propose to install the new culverts slightly below
the existing stream bed elevation where bedrock is not encountered to minimize impact to
Wildlife habitat and allow the existing stream gradient to remain as unchanged as physically
possible.
The best management practices will be used to minimize and control sedimentation and
erosion on this project. The construction foreman will review all erosion control measures daily
to ensure sedimentation and erosion controls are being effectively controlled. If the planned
devices are not functioning as intended, they will immediately be replaced with better devices.
The silt fences and other erosion control devices will be in place prior to pipe construction and
will remain in place until the project is stabilized.

;A. temporary slit fence is commoniy used ar- the toe of a fill section to prevent off-
site sedimentation. It is made of permeable filter fabric buried at the boaom.
stretched and supported by steel posts. The silt fence reduces the water flow while
retaining the sediment. Thev may also be used to divert wale: flow to protected
outlets. Silt fences need to be checked after each significant rainfall to ensure there
effectiveness. They must be maintained on a regular basis. Silt fences shall not be
installed across streams, ditches. or waterways.
AREAS OF USE:
• At toe of All sections where sediment runoff can be stored and contained
inside the project limits.

SILT BASIN TYPE-B:
77
A silt basin type-B is a temporary basin built to coilect sed.imenE flowing through a
drainage way. The silt basin is built at the base of the ditch with its length being aE
least 2 times the width of the basin. The type-B silt basin is generally built in
conjunction with temporary rock silt checks and other devices that control or slow
down water flow. This device must be monitored closely and cleaned out on a
regular basis until grass is established along the ditch line and sedimentation is no
longer a problem.
AREAS of USE:
• In conjunction with temporary rock silt checks and other devices used in
drainage ditches.
DESIGN CRITERIA:
• Width - variable
• Length - 2 times width
• Depth - 2 ft. minimum storage - 1800 cubic feer/acre (equals L x W x D)

Arock pipe iniet protection type-A is a h'rseshoe shaped struc=; : with*a built-in
sediment storage area around the ourside perimeter of _hA stucwre. The type-A
rock pipe-inlet protection shall be used at pipe inlets no larger than 36 inches in
diameter where it is receiving flow from several directions. The type-A rock pipe
inlet protection utilizes class-B stone lined with n5 or 457 stone to protect drainage
pipe structures by trapping sediment before it enters. They have a sediment storage
pit which is designed by the same procedures as a silt basin.
AREAS OF USE:
• At inlets to pipes no larger than 36 inches in diameter where it receives flow
from several directions.
• In areas where it can be cleaned and maintained on a regular basis.
DESIGN CRITERIA.:
• Structural stone - class-B stone
• Sediment control stone - #5 or #57 stone
• Sediment storage area - 1800 cubic ft./acre
• Dam height - 3 ft. minimum

adjacent to the stream.
