Subject: Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: Charlotte Water
Wastewater Treatment Plant: Irwin Creek WWTP
NPDES #: NC0024945, Mecklenburg County

Dear Kevin Heavner:

The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
renewal submitted by Charlotte Water, Irwin Creek WWTP (NC0024945) for the following Significant Industrial
User (SIU). The submission was received by the Division on 04/11/2023.
SIU # SIU NAME
1009 Qualawash Holdings, LLC
The review indicates that the IUP is adequate and meeting 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 t he list of
Significant Industrial Users (SIUs). Pursuant to 15A NCAC 2H .0907(b) either the Division or the permittee may
initiate pretreatment program revisions.
Federal and State pretreatment regulations require the local delegated pretreatment program t o 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 Al Woodall [email: [e-mail]] at [phone] or Keyes McGee at [phone]
[email: [e-mail]].
