Dear Mr. Dellario:
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 NCGO10000 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.
Title 15A NCAC 4B .0118(a) and the NCGO1 permit require that the following documentation be kept on file
at the job site:

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. 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, 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,
Shannon Leonard
