Dear Dr, Williamson:
In accordance with your application for a discharge permit received on November 19,
2012, we are forwarding herewith the subject certificate of coverage 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).
Please take, notice that this certificate of coverage is not transferable except after notice to
the Division of Water Quality. The Division of Water Quality may require modification or
revocation and reissuance of the certificate of coverage.
A requirement of this permit is compliance with the Division OLEnergy, Mineral and
Land Resources' (DEMLR) Mining Permit; therefore, you must hold a renewed DEMLR
Permit before any mining industrial activities take place.
Please note that mine dewatering wastewater includes wet pit overflows caused solely
by direct rainfall and groundwater seepage for this type of mining operation. Any discharge of
this water (and any stormwater commingled with it) is subject to the effluent limitations in this
permit.
This general permit allows the discharge of stormwater and certain types of wastewater
from your facility. In your application, you specified that only mine dewatering water would be
discharged from this facility. If separate point -source discharges of stormwater occur (i.e.,
stormwater not combined with mine dewatering water), you will be required to adhere to the
conditions in this permit for stormwater discharges.
