Dear Mr. Burnett:
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 undertaken, as is
required by Title 15A NCAC 4B .0129.
As of April 1, 2019, all new construction activities are required to complete and submit an electronic
Notice of Intent (NOI) form requesting a Certificate of Coverage (COC) under the NCG010000
Construction Stormwater General Permit. This form MUST be submitted prior to the commencement
of any land disturbing activity on the above named project. The NOI form may be accessed at
deq.nc.gov/NCGO1. Please direct questions about the NOI form to Annette Lucas at
[e-mail] or Paul Clark at [e-mail]. After you submit a complete and
correct NOI Form, a COC will be emailed to you within three business days. Initially, DEMLR will
not charge a fee for coverage under the NCGO1 permit. However, on or after May 1, 2019, a $100 fee
will be charged annually. This fee is to be sent to the DEMLR Stormwater Central Office staff in
Raleigh.

1. The approved E&SC plan as well as any approved deviation.
2. The NCGO1 permit and the COC, once it is received.
3. Records of inspections made during the previous 30 days.
Also, this letter gives the notice required by G.S. I I3A-61.1(a) of our right of periodic inspection to
insure compliance with the approved plan.
North Carolina's Sedimentation Pollution Control Act is performance -oriented, requiring protection
of existing natural resources and adjoining properties. If, following the commencement of this project,
the erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation
Pollution Control Act of 1973 (North Carolina General Statute 113A-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 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,
Shannon Leonard

Figure 6.83b Stone check dam stone should be placed over the channel banks to keep water from cutting around the
dam.
Maintenance Inspect check dams and channels at least weekly and after each significant (1/2
inch or greater) rainfall event and repair immediately. Clean out sediment,
straw, limbs, or other debris that could clog the channel when needed.
Anticipate submergence and deposition above the check dam and erosion from
high flows around the edges of the dam. Correct all damage immediately. If
j significant erosion occurs between dams, additional measures can be taken
such as, installing a protective riprap liner in that portion of the channel
(Practice 6.31, Riprap-line and Paved Channels).
Remove sediment accumulated behind the dams as needed to prevent damage
to channel vegetation, allow the channel to drain through the stone check dam,
and prevent large flows from carrying sediment over the dam. Add stones to
dams as needed to maintain design height and cross section.
