Subject: Pretreatment Review of Industrial User Pretreatment Permit
City of Durham
NPDES #:N00047597 (South Durham WWTP)
Dear Mr. Battle:
The Pretreatment, Emergency Response and Collection Systems (PERCS) Unit of the Division of Water
Resources has reviewed the Industrial User Pretreatment Permits (IUP) renewal submitted by the City of
Durham. The draft IUP was received by the Division on January 27, 2020, additional information was
requested and was received with signed copy on March 6, 2020 and March 12, 2020.
IUP # sIU
2016 1 Unifirst Corporation
The review indicates the IUP is adequate and meet the minimum requirements of 15A NCAC 2H .0905
and .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained in the Division's database, has been
updated accordingly.
Federal and State pretreatment regulations require the local delegated pretreatment program to
effectively control and document the discharge of wastewater from Significant/Categorical Industrial
Users to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or
comments, please contact me at 919-707-3627 [email: [e-mail]].
Sincerely,
DocuSigned by:
