Dear April L. Mason:
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 eNOI 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.

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
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, 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,
amera Eplin,
Regional Engineer

MODIFICATIONS REQUIRED FOR APPROVAL
Project Name: TBMNC Building 804 Phase 1
Project ID: RANDO-2023-031
County: Randolph
Modifications pursuant to applicable North Carolina General Statutes and/or Regulations:
1. A dominant strategy for erosion control at portions of the overall project involve pumping
sediment through a silt bag and this is likely to occur prior to 3-5 days of standard design
settling time. It is recommended that polyacrylamides be added to diversion waddles and/or
basins when practical. This would maximize the potential for settling of sediment before the
pumps/silt bags are utilized. This site must be managed to prevent violations of surface
water quality turbidity standards in the receiving streams.
2. Additional measures may be required - The applicant is responsible for the control of
sediment on-site. If the approved erosion and sedimentation control measures prove
insufficient, the applicant must take those additional steps necessary to stop sediment from
leaving this site. [15A NCAC 4B .0115]
