Subject: Pretreatment Review of Headworks Analysis (HWA)
And Industrial User Pretreatment Permit (IUP)
Program: City of Kings Mountain; NPDES #: NC0020737; Cleveland County
Dear Ms. Meek:
The PERCS Unit of the Division of Water Resources has reviewed the updated HWA and the IUP
modifications submitted by the City of Kings Mountain for the following Significant Industrial
Users (SIUs). The HWA and the IUPs were received by the Division on February 19, 2020 and
March 4, 2020. Additional information was requested and was received on March 24, 2020.

The review indicates that with the following observation, the Division concurs with the HWA
calculations and the IUPs are adequate and the minimum requirements of 15A NCAC 2H .0905
and .0916 and 40 CFR 403.8(f)(1)(iii) are met. The submitted allocation table was not consistent
with the one in the Division's database.
Silver: Silver is over allocated on paper. As long as the POTW effluent is below the PQL, the POTW
would be considered in compliance. It is recommended that the POTW start to investigate the
sources of silver and proactively work with the major contributors to reduce silver in their
wastestreams.

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 me at 919-707-3627 [email: [e-mail]].
Sincerely,
