Dear Mr. Taveras:

Subject: General Permit No. NCG020000
The Quartz Corp USA—
Beaver Creek Mine
COC NCG020710
Mitchell County
In accordance with your request for renewal of a discharge permit received on June 30, 2014, 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 Energy, Mineral, and Land Resources. The Division may require modification or revocation and
reissuance of the certificate of coverage (COC).
Please be advised that EPA Region 4 staff who performed a Compliance Sampling Inspection (CSI) at
the end of March 2015 and follow-up sampling in June 2015 at other industrial mineral mines in North
Carolina raised concerns about metals levels in the discharges. The Stormwater Permitting Program
identified mines like this one that have similar activities. During the term of this General Permit, this site may
be evaluated further for an alternative permitting action, such as applying to the Division of Water Resources
(DWR) for an individual NPDES discharge permit (or modification of its existing wastewater individual 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.
