Dear Mr. Shumate:
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 NCG010000 permit require that the following documentation be
kept on file at the job site:

MODIFICATIONS REQUIRED FOR APPROVAL
Project Name: Greensboro Science Center Parking Expansion
Project ID: GUILF-2023-028
County: Guilford
Modifications pursuant to applicable North Carolina General Statutes and/or Regulations:
1. 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]
2. The NCG01 has a $100 yearly fee and our office often receives closure inspection requests
days prior to yearly NCGO1 fee payment due dates. Be advised the project requires a closure
inspection report by DEMLR prior to filing the Notice of Termination (NOT) to terminate
NCGO1 coverage. The closure inspection should not be requested until after the site has
achieved full vegetative stabilization and measures have been removed. The removal of
temporary ESC measures, including basins, requires prior approval. Often, a full growing
season is necessary between initial seeding/mulching and removal of measures. Please plan
your construction accordingly to avoid contacting our office prematurely for a closure
inspection. Also be advised you may be asked for representative site pictures prior to a
closure inspection. [General Comment]
