Dear Ms.Nguyen:
This office has reviewed the subject erosion and sedimentation control plan. We find the plan to be
acceptable and hereby issue this Letter of Approval. The enclosed Certificate of Approval must be
posted at the job site. 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
eNOl 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 is required to apply for his/her own COC.

Title 15A NCAC 4B .0118(a)and the NCGO1 permit require that the following documentation be kept
on file at the job site:
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 12 months.
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. This permit allows for a land-disturbance,
as called for on the application plan, not to exceed the approved acres. Exceeding the acreage will be
a violation of this permit and would require a revised plan and additional application fee.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,
YWV 4(j2 .
