Dear John Chuilli:
In accordance with your application for a discharge permit received on September 1st, 2020, we are
forwarding herewith the subject certificate of coverage (COC) to discharge under the subject state -
NPDES general permit. This permit is issued pursuant to the requirements of North Carolina
General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the US
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
In order to comply with the conditions of NCG140000 to which you are now subject, you are
required to do the following:
➢ Implement a SWPPP before beginning operations.

The 7Q10 base flow for Beaverdam Creek at this location has not been estimated because these
waters are tidally influenced, and a low flow condition estimated to be as protective as the 7Q10
flow is not available. However, if dewatering flows are ever large enough to impact the uses of the

receiving waters, the Division may specify a dewatering flow limit to protect its shellfishing use and
aquatic life in these waters.
This permit does not allow discharges that will violate water quality standards in the downstream
waters. Those waters contain sensitive species that could be displaced or distressed by a large
volume of the discharge and also contain shellfish species, which if contaminated and eaten by
humans, could result in serious adverse health effects. Therefore, any time the discharge may be
large enough to exceed the 50 percent mixing ratio with the receiving waters, it is important to
reduce the volume of release to protect public health and the environment.
This project is located in one of North Carolina's 20 coastal counties. Coastal stormwater
management rules (15A NCAC 2H .1000) may require an additional State Stormwater Permit
(different from the NPDES mining activities discharge permit). Please contact Georgette Scott in
the Wilmington Regional Office at [phone] to determine if you will be required to submit
an application for a State Stormwater permit.
Please take notice that this certificate of coverage is not transferable except upon approval from the
Division of Energy, Mineral, and Land Resources (Division). The Division may require modification
or revocation and reissuance of the certificate of coverage.
This permit does not affect the legal requirements to obtain other permits which may be required
by the Division of Water Resources, the Coastal Area Management Act, or any other federal or local
government permit that may be required.
If you have any questions concerning this permit, please contact Brittany Carson at [phone]
or by email at brittany.carson(@ncdenr.gov.
Sincerely,
