Subject: Pretreatment Review of Industrial Waste Survey (IWS)
City of Rockingham (NPDES Permit No. NC0020427)
Richmond County
Dear Mr. Cobler:
The PERCS Unit of the Division of Water Resources has reviewed the Industrial Waste Survey (IWS) for the
City of Rockingham. The IWS was initially received by the Division on June 11, 2019, followed by more
information received on June 18, 2019.
The review indicates that the IWS is adequate and meets the minimum requirements of 40 CFR 403.8 (f)
(2). Proper completion of an Industrial Waste Survey is required by Part IV, Section (D), of your NPDES
permit.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any Significant
Industrial Users (SIUs), as defined by 15A NCAC 02H .0903(b)(33) (A) through (D), are identified and
subsequently added to the City's Pretreatment Program. This includes the evaluation of new IUs before
they commence discharge and the evaluation of existing IUs determined to be not SIUs that make changes
to their process.
Next IWS Due Date: Your next updated IWS is due on June 30, 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 Monti Hassan at [phone] [email: Monti. [e-mail]].
