Dear Mr. Whitley:
In accordance with your application for a discharge permit received on May 21, 2018, we are
forwarding herewith the subject certificate of coverage (COC) 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 upon approval of the
Division of Energy, Mineral, and Land Resources. The Division of Energy, Mineral, and Land
Resources may require modification or revocation and reissuance of the certificate of coverage.
Consideration must be given to the fact that mine dewatering at your site has the potential to impact
adjacent wetlands. The specific requirements for mine dewatering at facilities near wetlands can be
found in Part IV, Section D of your permit. If, at any time, pumping activities occur onsite, you must
obtain a Division approved Pumping Operation and Monitoring (POM) Plan. Pumping mine
dewatering wastewater without Plan approval will be subject to enforcement action. Contact Thad
Valentine at the Raleigh Regional Office at [phone] for assistance with your POM Plan.
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.
Please be aware that there is a Total Maximum Daily Load (TMDL) in effect for this watershed.
Information about this TMDL can be found on Division of Water Resources' website:
hitps://deg.nc.gov/about/divisions/water-resources/plwmin modeling-assessmentttmdls. In Part I,
Section A, the General Permit explains that for discharges to watersheds affected by a TMDL,
coverage under this permit may depend on the site demonstrating that discharges have no reasonable
potential to violate applicable water quality standards for specified pollutants.

Per the requirements of the Neuse Riparian Buffer Rule, all stormwater drainage to stream buffers,
from portions of this site that have been constructed after July 22, 1997, must meet diffuse flow
requirements per 15A NCAC 2B .0233. Diffuse flow requirements are described in Chapter 8 of the
North Carolina Stormwater BMP Manual, available at: bitp://deg.nc.gov/abouttdivisions/energy-
mineral-land-resources/enerey-mineral-land-oermit-guidance/stormwater-bmo-manual.
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 Alaina Morman at telephone number
[phone] or by email alaina.mormanna ncdenr.gov.
