Subject: Pretreatment Review of Industrial User Permit
City of Salisbury (NPDES Permit No. NC0023884)
Rowan County
Dear Ms. Basinger:
The PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) renewals submitted by the City of Salisbury for the following Significant Industrial Users (SIUs). The
IUPs and the supplementary documents were received by the Division on August 26, 2019.
IUP No.
SIUs
0002
Nouryon Surface Chemistry, LLC
0036
CSP Composites, LLC
The review indicates, with the observation below, that the IUPs are adequate and the minimum
requirements of 15A NCAC 02H .0905 and .0916, and 40 CFR 403.8(f)(1) are met.
CSP Composites, LLC: Even though, as listed, CSP Composites is covered as Categorical Industrial (40 CFR
463, Plastics Molding), it appears that there are no pretreatment standards for any subpart of this
category. Please list them as N/A for 40 CFR Category in the IUP.
Allocation Table (AT): It appears that AT needs to be updated with Total Phosphorus limit of 130 Ibs/day
as indicated in the Nouryon IUP. Please submit an updated AT for our records.
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] or email [e-mail].
