Dear Mr. Cook:
This office has reviewed the subject erosion and sedimentation control plan. We find the plan to
be acceptable with modifications and hereby issue this letter of Approval with Modifications.
The Modifications Required for Approval are listed on the attached page. This plan approval
shall expire three (3) years following the date of approval, if no land -disturbing activity has been

Please be aware that your project will be covered by the enclosed NPDES Construction
Stormwater General Permit NCG010000. Please become familiar with all the requirements and
conditions of this permit in order to achieve compliance.
Please be advised that Title 15A NCAC 4B .0118(a) requires that a copy of the approved erosion
control plan be on file at the job site. Also, you should consider this letter to give the Notice
required by G.S. 113A -61.1(a) of our right of periodic inspection to insure compliance with the
approved plan.

North Carolina's Sedimentation Pollution Control Program is performance -oriented, requiring
protection of existing natural resources and adjoining properties. If, following the
commencement of this project, it is determined that the erosion and sedimentation control plan is
inadequate to meet the requirements of the Sedimentation Pollution Control Act of 1973 (North
Carolina General Statute I I3A-51 through 66), this office may require revisions to the plan and
implementation of the revisions to insure compliance with the Act.
Acceptance and approval of this plan is conditioned upon your compliance with Federal and
State water quality laws, regulations, and rules. In addition, local city or county ordinances or
rules may also apply to this land -disturbing activity. This approval does not supersede any other
permit or approval.
Please note that this approval is based in part on the accuracy of the information provided in the
Financial Responsibility Form, which you have provided. You are requested to file an amended
form if there is any change in the information included on the form. In addition, it would be
helpful if you notify this office of the proposed starting date for this project. Please notify us if
you plan to have a preconstruction conference.
Your cooperation is appreciated.
Sincerely,
Ousmane Sidibe

GROUND COVER - Whenever land disturbing activity is undertaken on a tract
comprising more than one acre, if more than one continguous acre is uncovered a
p 9
ground cover sufficient to restrain erosion must be planted or otherwise provided
within 14 calendar days on that portion of the tract upon further active construction is
riot being undertaken, provided that this subsection shall not apply to cleared land
forming the basin of a reservoir to be inundated.
GRADED SLOPES AND FILL - The angle for graded slopes and fills shall be no greater
that the angle which can be retained by the vegetative cover or other adequate erosion
control devices or structures. In any event slopes greater than 3:1 , shall be seeded
within 7 calendar days following any phase of grading; on other areas permanent
ground cover for all disturbed areas within 14 calendar days of completion of any
phase of grading, be planted or otherwise provided with ground cover, devices, or
structures sufficient to restrain erosion.
SEED RED PREPARATION - The seed bed shall be prepared by pulverizing the soil in a
manner to a depth of three inches for field conditions or slopes that are 3:1 or flatter
and/or to a depth of one inch to three inches as determined on site for slopes steeper
than 3:1 . Tillage shall continue until a well pulverized, firm, reasonably uniform seed
bed is prepared conforming substantially to ground elevations as shown on the plans
and/or as was exisitng prior to construction, blending uniformly into adjacent
topography. All stones, roots, sticks, rubbish, and other objectionable material shall
be removed.
The following material shall be used for reseeding disturbed areas: (note that all rates
are per 1000 sf)

suitable outlet.
4 Use geotextile fabrics because they improve stability of the

Maintenance
inspect sediement fences at least once a week and after each rainfall. Make any
required repairs immediately.
1. Should the fabric of a sediment fence coliiapse, tear, decompose or become
ineffective, replace it promptly.
2. Remove sediment deposits as necessary to, provide adequate storage volume for
the next rain and to reduce pressure on the fence. 'Fake care to avoid undermining
the fence during cleanout.
3. Remove all fencing materials and unstable sediment deposits and bring the area
to grade and stabilize it after the contributing drainage area has been properly
stabilized.

Porous Baffles
Construction Specifications
1. Grade the basin so that the bottom is level front to bock and side
to side.
2. Install pasts across the width of the sediment trap (6.2rn
sediment fence).
3. Steel posts should be driven to a depth of 24 inches, spaces a
maximum of 4 feet apart, and installed up the sides of the basin
as well. The top of the fabric should be 6 inches higher than the
invert of the spillway, Tops of baffles should be 2 inches lower
than the top of the berms.
4, Install at least three rows of baffles between the inlet and outlet
discharge point. Basins less than 20 feet in length may use 2
baffles.
6. When using pasts, add a support wire or rope across the top of
the measure to prevent sagging.
6. Wrap porous material like the jute backed by coir material, over
the top wire. The fabric should have five to ten percent openings in
the weave. Attach fabric to a rope and a support structure with zip
ties, wire or staples.
7. The bottom and sides of the fabric should be anchored in a trench
or pinned with ®inch erosion control matting staples.
6. Do not splice the fabric but use a continuous piece across the
basin.

SPECIFICATIONS: 1 Ensure that the subgrade for the filter and rfiprap follows
the required lines and grades as shown in the p -an. Compact any
fill required in the subgrade to the density of tt=e surrounding
undisturbed material. Low areas in the subgrode on undisturbed
soil may also be filled by increasing the riprap y; ickness.
2 The riprap and gravel filter must conform to the specified
grading limits shown on the plans.
3 Filter cloth, when used, must meet design requirements and be
properly protected form punching or tearing during installation. Repair
any damage by removing the riprop and placing another piece of filter
cloth over the damaged area. All connecting j6nts should overlap a
minimum of 1 ft. If the damage is extensive, replace the entire
filter cloth.
4e Riprap may be placed by equipment, but take care to avoid damaging
the filter.
5 The minimum thickness of the riprap should De 1.5 tunes the
maximum stone diameter.
6 Riprop may be field stone or rough quarry sone, It should be
hard, angular, highly weather—resistant and well graded.
7 Construct the apron on zero grade with no vverfall at the end. Make
the top of the riprap at the downstream end level with the receiving
area or slightly below it.
S Ensure that the apron is properly aligned wit~ the receiving stream
and preferably straight throughout its length. if ;a curve is needed to
fit site conditions, place it in the upper section f the apron.
9 Immediately after construction, stabilize all "rsturbed areas with vegetation.
MAINTENANCE; Inspect riprap outlet structures after heavey rains to see
if any erosion around or below the riprop has to -,an place
or if stones have been dislodged. Immediately rr,a e all
