Subject: General Permit No. NCG210000
Wyeth, LLC — Sanford Plant
COC No. NCG210444
Rescission of NCGNE0232
Lee County
In accordance with your application for a discharge permit received on May 9, 2016, 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). In
conjunction, the No Exposure Certification No. NCGNE0232 for this facility is hereby rescinded.
The company also requested that stormwater discharge outfall 005 be granted representative
outfall status (ROS) because it discharges stormwater from the area where woodchips are stored at
this facility. The Division hereby approves your request based on the circumstances of exposure at
this site and the information provided during and after our site visit on July 22, 2015. In accordance
with 40 CFR § 122.2 1 (g)(7), you are authorized to sample outfall 005 as a representative outfall. This
approval is effective with the initial sampling event under this permit. However, the permit still
requires Qualitative Monitoring be performed at all SDOs, regardless of representative status.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit to document
that ROS has been approved. If changes in drainage areas, structures, processes, storage practices, or
other activities occur that significantly alter the basis of this approval, ROS may no longer be valid.
You would either resume sampling all SDOs, or reapply to this office for representative outfall status
based on updated information.
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.
