Subject: Pretreatment Review of Industrial User Pretreatment Permit Renewals
Program: City of Monroe
WWTP: City of Monroe WWTP - NPDES #: NC0024333
Union County
Dear Mr. Ketchum:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) renewals submitted by the City of Monroe for the following Significant Industrial Users (SIUs). The IUPs
were received by the Division on May 23, 2022.
SIU #
SIU NAME
CM-15
ATI Allvac
CM-29
Charlotte Pipe and Foundry Company, Plastic Division
CM-01
Goulston Technologies, Inc.
CM-35
NC BioGas, LLC
CM-16
Norton Door Controls
CM-25
ORO Manufacturing Company
The review indicates that the IUPs are adequate and meet the minimum requirements of 15A NCAC 2H .0905
and .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained in the Division's database, has been
updated accordingly.
Regardless of this approval action today, within 180 days of the effective date of any reissued NPDES permit (or
any subsequent NPDES permit modification) 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 (SIU's).
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.
