WILMINGTON, NORTH CAROLINA 28403
Subject: Permit No. WQ0018087
Alpek Polyester – Cape Fear
Manufacturing Facility SDU
Surface Disposal of Residuals
Brunswick County
Dear Mr. Hendrickson
In response to your permit name change request received on February 8, 2024, and subsequent
additional information received on May 31, 2024, we are forwarding herewith Permit No. WQ0018087
dated August 21, 2024, to Alpek Polyester USA, LLC for the continued operation of the subject residuals
management program.
This permit is effective from the date of issuance through January 31, 2027, shall replace Permit
No. WQ0018087 issued on November 13, 2020, and is subject to the conditions and limitations specified
therein. The Permittee shall submit a renewal application no later than August 4, 2026.
During review of site history and groundwater monitoring trends during this name change
application, Wilmington Regional Office staff noted consistent exceedances of the groundwater standards
at the review boundary for several constituents of interest (i.e., Ammonia, Nitrate, Total Dissolved Solids,
Cobalt, and Arsenic). The Permittee hypothesized these exceedances were a result of disturbances that
occurred during the closure of the surface disposal unit (SDU) and surrounding site activities, and closure
of unit would show a reduction in constituent. However, trends for these constituents have only slightly
decreased or remained stable, while some constituents, like Ammonia in MW-2E, are increasing. Due to
the persistent groundwater exceedances present at the review boundary, the Division is requiring an analysis
of facility to demonstrate that these exceedances at the review boundary will not cause a violation of
standards at the compliance boundary pursuant to 15A NCAC 02L .0106(d).
Please note that the Permittee has utilized approximately 170,000 cubic yards of the SDU’s
194,000 cubic yard capacity, and that the SDU is no longer accepting residuals.
Please pay attention to the monitoring requirements listed in Attachments A and C for they may
differ from the previous permit issuance. Failure to establish an adequate system for collecting and
maintaining the required operational information may result in non-compliance.
