Subject: Pretreatment Review of Industrial User Pretreatment Permit Drop Request
Program: Charlotte Water; WWTP: Irwin Creek (NC0024945), Mecklenburg County
Dear Ms. Bell:
The Pretreatment, Emergency Response, and Collection Systems Unit (PERCS) 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 (SIU). This request was received by the
Division on January 3, 2020. 1 apologize for the late response.
IUP # SIU Name
1021 NCG-ERC LLC
The review indicates that the SIU ceased operation and no longer meets the definition of Significant
Industrial User. The SIU drop request is approved based on compliance with 15 NCAC 2H.0907(b) and
.0903(b) (33). The SIU list which is part of your approved pretreatment program is hereby modified.
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 [email: [e-mail]] at 919-707-3627.
Sincerely,
DocuSigned by:
