heiewitli 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

Agency dated October 15, 2007 (or as subsequently amended).
Please be aware that Williams Old Mill Branch (segment index number 18-68-1-10) is an impaired

multiple Total Maximum Daily Loads (TMDLs) that affect this watershed. Information about these
TMDLs can be found on Division of Water Resources' website: https://deq.ne.gov/about/divisions/water-
resources/plannin modeling-assessment/tmdls. 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 facility
demonstrating that discharges have no reasonable potential to violate applicable water quality standards
for specified pollutants.
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.
