In accordance with your application for a discharge permit received on February 08, 2020 we are

required to do the following:

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 waters The 7Q10 base flow for Huges Mill Creek at this
location is estimated to be < 0.00014 cfs; therefore, wastewater discharge to Sharron Creek
should be limited to 453 gallons per day (gpd) or less.
This general permit allows the discharge of stormwater and certain types of wastewater from your
facility. In your application, you specified that only wastewater would be discharged from this
facility. If separate point -source discharges of stormwater occur (i,e., stormwater not combined
with process wastewater), you will be required to adhere to the conditions in this permit for
stormwater discharges.
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 Brian Lambe in the
Wilmington Regional Office at 910-796-9800 to determine if you will be required to submit an
application for a State Stormwater permit.
Additionally, please see guidance on our website [https: //deq.nc.gov/about/divisions/energy-
mineral-land-resources/energy-mineral-land-rules/stormwater-programfpost-construction) for
mines located in Phase II Post -Construction areas. This guidance clarifies the applicability of
Session Law 2006-246 to mines located in Phase II Post -Construction areas. You may be required to
apply for a separate Post -Construction stormwater permit from the State or local government.
Please take notice that this certificate of coverage is not transferable except upon approval of 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 Michael Meloy at telephone number
[phone] or by email [e-mail].
Sincerely,
YLL�
