Dear Mr. Cherry:
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 (eNOI) form requesting a Certificate of Coverage (COC) under the NCG010000 Construction General
Permit. After the form is reviewed and found to be complete,you will receive a link with payment instructions
for the $100 annual permit fee. After the fee is processed, you will receive the COC via email. As the
Financially Responsible Party shown on the FRO form submitted for this project,you MUST obtain the COC
prior to commencement of any land disturbing activity. The eNOI form may be accessed
at deq.nc.gov/NCG01. Please direct questions about the eNOT form to the Stormwater Program staff in the
Raleigh central office. If the owner/operator of this project changes in the future, the new responsible
party must obtain a new COC.

1. The approved E&SC plan as well as any approved deviation.
2. The NCG01 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. 113A-61.1(a) of our right of periodic inspection to ensure
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, 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 113A-51 through 66), this office may require revisions to
the plan and implementation of the revisions to ensure 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.
Your cooperation is appreciated.
Sincerely,

Figure 8.83b 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
1 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,Rip rap-line and Paved Channels).
Remove sediment accumulated behind the darns 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.
