Pretreatment Review of Industrial User Pretreatment Permit Modification

WWTP: Rocky River Regional WWTP, NPDES #: NC0036269
Cabarrus County
Dear Ms. Metcalf:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modifications submitted by the Water & Sewer Authority of Cabarrus County for the following Significant
Industrial Users (SIUs). The IUPs were received by the Division on June 30, 2021.
SIU #
SIU NAME
1010
Atrium Health Cabarrus
1028
Americhem, Inc.
The review indicates that the IUPs are 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.
Regardless of this approval action today, within 180 days of the effective date of any reissued NPDES permit (or
any subsequent NPDES permit modification) the Permittee would be required to submit to the Division a written
technical evaluation of the need to revise local limits (i.e., an updated IWS, or documentation of why one is not
needed). This action may include revising, updating or adding to the list of Significant Industrial Users (SIU's).
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.
If you have any questions or comments, please contact Michael Montebello at (919) 707 -3624 [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
