Dear Ms. Metcalf:
The PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification submitted by the Water & Sewer Authority of Cabarrus County (WSACC) for the
following Significant Industrial User (SIU). The IUP modification was received by the Division on April 12,
2019.
IUP # SIU Name
1030 Heritage -Crystal Clean, LLC
The review indicates that the IUP is adequate 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]].
