Subject: Pretreatment Program Modification to Receive Reports Electronically from Its
Industrial Users (IUs) [Cross -Media Electronic Reporting Rule (CROMERR)]
Pretreatment Program: Charlotte Water
Wastewater Treatment Plant: Irwin Creek WWTP
NPDES# NC0024945, Mecklenburg County
Dear Bill Gintert:
On 12/09/2022 the NPDES Municipal Permitting Branch of the Division of Water Resources
received Charlotte Water's notice of intent to modify the pretreatment program's legal authority
and procedures to receive reports from Industrial Users electronically (CROMERR Application).
Charlotte Water currently receives wet ink signature pretreatment reports from IUs.
On 9/12/2023 the Municipal Unit received an email from Shirley Miller of EPA's Office of
Information Management (aka, The EPA CROMERR Team), titled "CONFIRMING CROMERR
COMPLIANCE: Status of Charlotte Water, SwiftComply Application." This email indicates "The
CROMERR program confirms that the Charlotte Water SwiftComply system is CROMERR
compliant," and "The means of official action on the program modification request is entirely at
the discretion of NCDEQ."
Division review of the complete application package indicates conformity with the PART 3 -
CROSS -MEDIA ELECTRONIC REPORTING (Code of Federal Regulations - Title 40, Chapter
I, Subchapter A, Part 3).
The Division will include in the Charlotte Water Irwin Creek WWTP (NC0024945) NPDES
permit renewal public notice a courtesy announcement of modification to the Charlotte Water
Pretreatment Program for CROMERR. The Division recognizes the proposed pretreatment
program change for CROMERR to be a non -substantial modification subject to approval
procedures in 40 CFR 403.18(d), and public notice or opportunity for hearing is not required for
non -substantial modifications. Charlotte Water's pretreatment program is approved to begin
utilizing the Charlotte Water SwiftComply System to receive and send electronic reports as
required.

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 Keyes McGee at [phone] [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
