Subject: Pretreatment Review of Industrial User Permit Modification
Town of Clayton (NPDES permit No. NC0025453)
Johnston County
Dear Mr. Warren:
The PERCS Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification submitted by the Town of Clayton for the following Significant Industrial User (SIU).
The IUP was initially received by the Division on February 26, 2020, followed by corrections received on
March 6, 2020.
IUP# SIU Name
0001-02 Grifols Therapeutics, Inc.
The review, with the most recent corrections, indicates that the IUP is adequate and the minimum
requirements of 15A NCAC 02H .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 support of the pretreatment program. If you have any questions or
comments, please do not hesitate to contact me at(919)707-3626,or email at [e-mail].
