This site will discharge to a receiving stream designated as High Quality Waters (HQW). The
General Permit imposes a more stringent TSS limit and a flow limit of 50 percent of the 7Q10 base
flow for all discharges to HQW-classified. The 7Q10 base flow for Williams Branch 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 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 Christine Hall 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 [e-mail].
Sincerely,
