APPROVAL of 401 Water Quality Certification
Mr. C.R. Styles
NC DOT
PO Box 250
Bryson City, NC 28713
Dear Mr. Styles:
You have our approval, in accordance with the attached conditions, to fill in 0.003 acres of wetlands or
waters for the purpose of paving SR 1389 as you described in your application dated December 4, 1997. After
reviewing your application, we have decided that this fill is covered by General Water Quality Certification
Number 3103. This Certification allows you to use Nationwide Permit Number 14 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 W. Fo this approval to be valid, you must follow 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 which conforms to Chapter 150B of the North Carolina General Statutes to the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 276 1 1-7447. 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,
P eston HowarZl, Jr. P.E.

Dear Mr. Johnson:
DIVISION OF HIGHWAYS
P. O. Box 250
Bryson City, NC 28713
December 4, 1997
GARLAND B. GARRETT JR.
SECRETARY

G

The North Carolina Department of Transportation is proposing to grade, drain, base
and pave primarily along the existing roadway of SR 1389, East Dicks Creek Road in Jackson
County. In order to construct this project in accordance with our current secondary road
standards and due to the replacement of two (2) pipe culverts in two unnamed tributaries of
East Dicks Creek (DEM Class C) 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 replacements in the unnamed tributaries of East Fork Dicks 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. Mark Davis, Habitat Coordinator Western
Mountain District, of the NCWRC to comment directly to you concerning the 404 Nationwide
permit request.

Mr. Bob Johnson

Also by copy of this letter, I am requesting authorization to proceed under Section 401
of the Clear Water Act from Division of Environmental Management. In addition, I am asking
Mr. Davis and Mr. Ed Ingle, Area Roadside Environmental Engineer (NCDOT), and Mr. Richard
Phillips (DEHNR), to comment directly to me concerning this permit request.
We would like to begin construction as soon as possible. If further information is
required, please advise. Your early review and consideration will be appreciated.

A temporary silt fence is commonly used at the tae of a fill section to prevent off-
site sedimentation. It is made of permeable filter fence buried
the water t m while
stretched and supported by steel posts. The ted retaining the -sediment. They may also be used to divert rainfall to ensure these
outlets. Silt fences need to be checked after each significant
milar basis. Silt fences shall not be
effectiveness. They must be maintained on a rem
installed across streams, ditches, or waterways.
AREAS OF USE
• At toe of fill sections where sediment runoff can be stared and contained
inside the project limits.

SILT BAm 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.
DEsicx CRrrmuA:
• Width - variable

Rocx PIPE INLET PROTEcrioN TYPE-A:
o ? .
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
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 ?e-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 - 1#5 or #57 stone
• Sediment storage area - 1800 cubic ftlacre
• Dam height - 3 ft minimum

Rocx SILT SCREEN:
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 rack -silt screen utilizes class B stone lined with lr'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 - T 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)
