Subject: Pretreatment Review of Industrial User Pretreatment Permit Drop
Program: Charlotte Water
Wastewater Treatment Plant: McAlpine Creek WWTP
NPDES#: NC0024970,Mecklenburg County
Dear Mr. Gintert:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) drop request submitted by Charlotte Water for the following Significant Industrial User (SILT). The
submission was received by the Division on February 17t1i,2023.
SIU# SIU NAME
3014 Charlotte Plating, Inc.
The review indicates the ILTP has been dropped by the Charlotte Water Pretreatment Program and the
documentation meets the minimum requirements of 15A NCAC 2H .0916 and 40 CFR 403.8(f)(1)(iii). The
allocation table,maintained in the Division's database,has been updated accordingly.
Within 180 days of the effective date of any reissued or modified NPDES permit 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(SIUs).Pursuant to 15A NCAC 211.0907(b)either the Division or the permittee may
initiate pretreatment program revisions.
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 Octavio Henriquez at (919) 707-3662 [email:
octavio.henriquezkncdenr.gov] Thank you for your continued support of the Pretreatment Program.
Sincerely,
