Dear Mr. Matt Law,
This office has reviewed the erosion and sedimentation control plan. We find the plan to be
acceptable and hereby issue this land-disturbing permit with modifications. Please read the permit
conditions carefully, return the signed color original to our office and keep the copy foryour records. A
copy of the enclosed land-disturbing permit must be posted at the job site. This letter gives the notice
required by GS 113A-61.1(a) and the New Hanover County Erosion and Sedimentation Control Ordinance
Article VIII Section 8.21 of our right of periodic inspection to ensure compliance with the approved plan.
As of April 1, 2019, all new construction activities are required to complete and submit an
electronic Notice of Intent(eN01) form requesting a Certificate of Coverage (COC) under the NCG010000
Construction General Permit. The COC must be obtained prior to the commencement of any land-
disturbing activity on the above-named project, according to State Stormwater requirements. The NOI
form may be accessed at httris://edocs.deq.nc.gov/Forms/NCG01-NOI . Please direct questions about the
NOI form to Paul Clark at [e-mail] you submit a complete and correct NOI Form,you

disturbance inspection. Once the project is stabilized and receives the final land-disturbance inspection,
you should file a Notice of Termination (NOT) with the State to final out the project.
A copy of the enclosed land-disturbing permit, a copy of the approved erosion and sedimentation
control plan as well as any approved deviations, records of inspections made during the previous 12

A preconstruction meeting is optional prior to land-disturbing activity on this project. Please
contact me at(910)798-7139 if you would like to schedule this meeting in our office. If you choose not to
have a preconstruction meeting,you must contact us with the date the land-disturbing activity will take
dace onsite and again once the initial erosion control measures are installed.
New Hanover County's Erosion and Sedimentation 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 Statutes 113A-51 through 66), and the New Hanover County Erosion and Sedimentation Control
Ordinance Article VIII Section 8.19 (f),this office may require revisions to the plan and its implementation
of the revisions to ensure compliance with the Act and Ordinance.
This land-disturbing permit will expire within 1 year following the date of approval, if no land-
disturbing activity has been undertaken, as required by the New Hanover County Erosion and
Sedimentation Control Ordinance Article VIII Section 8.18 (d). If no activity takes place within one year
after work has begun onsite, the permit will expire. Please contact this office to reactivate a permit that
has expired.
Acceptance and approval of this erosion control plan is conditioned upon your compliance with
Federal and State water quality laws, regulations and rules and local city or county ordinances or rules.
This land-disturbing permit approval does not supersede any other permits or approvals. It is the owner's
responsibility to have all the permits and approvals that are required, prior to beginning construction.
Please note this approval is based in part on the accuracy of the information provided in the
Financially Responsibility Form, which you provided.You are required to file an amended form if there is
any change in the information included on the form.
Your cooperation is appreciated,
