Subject: Pretreatment Review of Industrial Waste Survey
City of Lincolnton (NPDES #: NC0025496); Lincoln County
Dear Ms. Tunstall,
The Pretreatment, Emergency Response, and Collection Systems Unit (PERCS) of the Division of Water
Resources has reviewed the reviewed the Industrial Waste Survey (IWS) submitted by the City of
Lincolnton. This submission was received by the Division on September 30, 2019. Additional information
was requested and was received on January 17, 2020.
The review indicates that with the additional information received, the IWS is adequate and meets the
minimum requirements of 40 CFR 403.8 (f)(2). Proper completion of an Industrial Waste Survey is also
required by the City's NPDES permit. Please refer to the Comprehensive Guidance for North Carolina
Pretreatment Programs (Comprehensive Guide) for additional information and examples.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any Significant
Industrial Users (SIUs), as defined by NCAC 15A 2H .0903(b)(33) (A) through (D), are identified and
subsequently added to the City's pretreatment program. This includes evaluation of new IUs before they
commence discharge and of existing IUs determined to be not SIUs that make changes to their process.
Your next updated IWS is due on October 1, 2024, unless conditions at the POTW change significantly and
thus warrant an earlier submittal.
Thank you for your continued cooperation with the pretreatment program. If you have any questions or
comments, please contact me at [phone] [email: [e-mail]].
Sincerely,
DocuSigned by:
