Halifax County
Dear Mr. Gillham:
In accordance with your application for a discharge permit received on February 25, 2016, 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 be aware that operations cannot begin until the associated mining permit is issued.
When the operations move from this initial mining area to the next one, you must submit for a
modification to the COC since the receiving waters will change.
Please take notice that this certificate of coverage (COC) is not transferable except after notice
to the Division of Energy, Mineral and Land Resources (DEMLR). The Division may require modification
or revocation and reissuance of the certificate of coverage.
Coverage under this General Permit for this facility is granted with the condition that the
permittee performs additional sampling requirements as outlined in the amended conditions to the
COC. These special provisions were prompted by effluent limitations required as per 40 CFR 440.50; and
monitoring required under the 2015 EPA Multi -Sector General Permit (MSGP). The additional provisions
for this COC are included on pages 2-5 of the COC.
These additional parameters include metals and other constituents which may be present or will
help us interpret the measurements (such as estimating the amounts of metals that are in dissolved
form). The Division will consider the data upon submittal to determine the most appropriate permitting
actions. It is possible that this facility will be directed to apply for an individual NPDES stormwater
discharge permit; and to the Division of Water Resources (DWR) for an individual NPDES wastewater
discharge permit prior to the expiration of this General Permit in 2020.

This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Energy, Mineral and Land Resources, or permits required by the Division of
Water Resources (DWR), Coastal Area Management Act, or any other federal or local governmental
permit that may be required. If the conditions as stipulated in the COC are unacceptable to you, you
may apply sooner for an individual NPDES discharge permit.
If you have any questions concerning this permit, please contact Robert Patterson at
[e-mail] or [phone].
Sincerely,
