Mr. C.R. Styles
N.C. Dept. of Transportation
P.O. Box 250
Bryson City, NC 28713
Dear Mr. Styles:
You have our approval, in accordance with the attached conditions, to place fill material in acres of
wetlands or waters for the purpose of improving SR 1157, as you described in your application dated 16 April
1997. After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Number 3100. This Certification allows you to use General Permit Number 031 when it is
issued by the Corps of Engineers.
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) (6) and (7). For this approval to be valid, you must follow the
conditions listed in the attached certification. 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.
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.

401 ISSUE[)
GARLAND B. GARRETT JR.
SECRETARY
RECEIVE
QPR 2 2199,
-"VV/RCNMEMgl SCIFNzs
The North Carolina Department of Transportation is proposing to grade, drain, base
and pave primarily along the existing roadway of SR 1157, Cullowhee Mountain Road, in
Jackson County. In order to construct this project in accordance with our current secondary
road standards and due to the replacement of eight (8) pipe culverts and the extension of two
(2) pipe culverts in several unnamed tributaries of Cullowhee Creek (DEM Class C-Tr) we are
requesting authorization under Section 404 of the Clean Water Act.
I 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 extensions and the pipe replacements of the unnamed tributaries of
Cullowhee Creek, 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
streambed elevation where bedrock is not encountered to minimize impact to Wildlife habitat
and allow the existing stream gradients 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.
By copy of this letter I am asking Mr. David Yow, North Carolina Resources
Commission, District Fisheries Biologist to comment directly to you concerning the 404
Nationwide permit request.

TEMPORARY SILT FENCE:
A temporary silt fence is commonly used at the toe of a fill section to prevent off-
site sedimentation. It is made of permeable filter fabric buried at the bottom,
stretched and supported by steel posts. The silt fence reduces the water flow while
retaining the sediment. They may also be used to divert water 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 = be
installed across streams, ditches, or waterways.
AREAS OF USE:
• At toe of fill sections where sediment runoff can be stored and contained
inside the project limits.
DESIGN CRITERIA:
Material With Wire Without Wire
Fabric Type 3 Class A Type 3 Class B
Steel posts length 5 ft 5 ft.
Post spacing 10 ft. 6 ft. maximum

SILT BASIN TYPE-B:
A silt basin type-B is a temporary basin built to collect sediment flowing through a
drainage way. The silt basin is built at the base of the ditch with its length being at
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 feet/acre (equals L x W x D)

ROCK PIPE INLET PROTECTION TYPE-A: o 10h
A rock pipe inlet protection type-A is a horseshoe shaped structure with a built-in
sediment storage area around the outside perimeter of the structure. 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 #5 or #57 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

ROCK SILT SCREEN: M
Mw A rock silt screen is a low-level dam structure to be used in streams below culvert
sites. Rock silt screens shall be used to trap sediment transported by running water
and shall be placed in the stream below the construction site within the right-of-
way or easement boundary. The rock silt screen utilizes class B stone lined with #5
or #57 stone to produce a ripple-effect in the stream to settle the larger sediment
particles transported in the stream from the construction site. The trapped sediment
shall be cleaned out before the device is removed from the stream.
AREAS OF USE:
• In live streams below construction sites where construction occurs in or
adjacent to the stream.
• In live streams below a culvert construction site.
• Where it can be cleaned before it is removed from stream.
DESIGN CRITERIA:
• Structural stone - class B stone
• Sediment control stone - # 5 or # 57 stone
• Dam height - 1.5 ft. minimum and 3 ft. maximum ( shall not be higher than
1 ft. above normal flow of stream)
