Date Received by LQS: March 17, 2023
Plan Type: New
Dear Mr. McSwain:
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 NCGOl 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 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.

1. Sheet C-363 contains errors related to elevations for the northern-most basin on that sheet. Modify
that sheet to provide the correct basin elevations and provide that updated sheet to our office within 2
weeks of receiving this letter. The same sheet shows basin top embankment widths of less than 5
feet for both basins. Skimmer basin minimum embankment width should be at least 5 feet. Please
correct. Lastly, utilizes at least three baffles per basin.
2. Sheet C-363 shows a temporary diversion berm on the northern side of the Limits of Disturbance
(LOD). The referenced diversion stops near the corner of the LOD and picks back up on the eastern
side of the LOD. Extend that diversion all the way around the northeastern corner of the LOD on that
sheet.
3. Sheet C-363 should include silt fence just inside the LOD along the entire eastern side of the LOD.
4. Modify the Skimmer Sediment Basin Table on Sheet C-455 to clearly show the emergency spillway
elevation for each basin. Provide the updated sheet to our office within 2 weeks of receiving this
letter.
5. Additional measures may be needed along haul roads to divert surficial drainage away from the haul
road or through the haul road. Utilize measures such as compost socks and/or temporary culverts
under the road, as needed. Additionally, install stone outlets in silt fence in low areas as needed.
6. Other 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]

The NC Construction General Permit(also known as"NCG01")was renewed on April 1,2019.The updated permit
does not significantly change the measures that are required to be implemented on construction sites. However,
there are some organizational and technical updates to the permit as described below. Most notably,there is a new
process in which construction sites will obtain official coverage under an NCG01 permit through an electronic
process. DEMLR worked with a broad team of stakeholders to make all of these updates. If you have questions,
contact Annette Lucas at [e-mail] or(919)707-3639.
