WQC 401 Project #970584
a
You have our approval, in accordance with the attached conditions, to place fill material in 180 linear
feet of waters for the purpose of improving SR 1104, as you described in your application dated 23 June
1997. 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 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 specked 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 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 Dorney at 919-733-1786.
Sincerely,
44tono d, Jr. .

Dear Mr. Johnson:

RECEIVED
JUN
ENVIR04NTAL 1?IENCE$
The North Carolina Department of Transportation (NCDOT) is proposing to grade, drain,
base, and pave SR 1104, Mulberry Road, primarily along the existing roadway. In order to
construct this project in accordance with our current secondary road standards and due to the
proximity of a trout stream (Mulberry Creek and tributaries, DEM Class C - Trout Water) and
extension of pipe culverts, we are requesting authorization under Section 404 of the Clean Water
Act.
I am sending a straight-line diagram with the proposed erosion control, stream, stream
bank, and construction limits at various sites along the project where we will be in conflict with
the streams. In addition, I am sending a typical section of the road, cross-sections, drawings for
pipe culvert extensions, general notes and standards on some erosion control measures, and a
marked map. We propose to install all the new culverts slightly below the existing streambed
elevations where bedrock is not encountered to minimize impacts to wildlife habitats and allow
the existing stream gradients to remain as unchanged as is 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 are being effectively controlled. If the planned devices are
not functioning as intended, they will immediately be replaced with better devices. The rock silt
screens and other erosion control devices will be in place prior to pipe culvert construction and
will remain in place until the project is stabilized.

Mr. Bob Johnson

June 23, 1997
By copy of this letter, I am asking Mr. Mark Davis, North Carolina Wildlife Resources
Commission (NCWRC) Western Mountain Region Coordinator, 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 Mulberry Creek and I am asking Mr. Davis and Mr. Ed Ingle, Area Roadside
Environmental Engineer (NCDOT) 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 like to begin construction as soon as possible. If further information is
required, please call me at [phone]. Your early review and consideration will be greatly
appreciated.
Sincerely,
W. T. Anders n

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 no 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-BI
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)

TEMPORARY ROCK SILT CHECK TYPE-B:

A temporary rock silt check type-B (also called check dam) is a small dam with a
weir used to reduce gullying in drainage ditches that are to be filled or
permanently stabilized at a later date. These type-B rock silt check's help reduce
the flow velocity and are generally made of class-B stone. They are used in ditches
during construction where the grade meets and/or exceeds 3%.
AREAS OF USE:
• In channels, roadside ditch outlets, temporary silt ditches, and temporary
diversions.
• In conjunction with type-B silt basins.
DESIGN CRITERIA:
• Center of rock silt check shall be at least 1 foot lower than the outer edges
(top of channel sides)
• The spacing (ft.) = (3 / % of ditch grade) X 100 ft.

ROCK PIPE INLET PROTECTION:
S
A rock pipe inlet protection is a horseshoe shaped structure with a built-in
sediment storage area around the outside perimeter of the structure. The rock pipe
inlet protection shall be used at pipe inlets no larger than 24 incheg in diameter
where it is receiving flow from several directions. The 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. This device can also be used
around the inlet of temporary slope drains where space is limited at the outlet end
of the slope drain such that a basin or other device can not be used.
AREAS OF USE:
• At inlets to pipes no larger than 24 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:
(11-1 11
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)
