Subject: Pretreatment Review of Industrial User Permit Drop
Rocky River Regional WWTP (NPDES Permit No: NC0036269)
Program: Water & Sewer Authority of Cabarrus County
Cabarrus County
Dear Ms. Metcalf:
The PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) drop request submitted by the Water & Sewer Authority of Cabarrus County (WSACC) for the
following Significant Industrial User (SIU). The IUP drop request was received by the Division on June 10,
2019.
IUP # SIU Name
1043 Organic Dyes & Pigments
The review indicates that the IUP drop is adequate, as the industry ceased their operation and discharge
of process wastewater to the POTW and the minimum requirements of 15A NCAC 2H .0905 and .0916 and
40 CFR 403.8(f)(1)(iii) are met.
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 Monti Hassan at [phone] [email: Monti. [e-mail]].
