Subject:
Pretreatment Review of Industrial User Pretreatment Permit Modification
Program: City of Greensboro
WWTP: T.Z. Osborne WRF, NPDES # NC0047384, Guilford County
Dear Ms. Varinoski:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment
Permit (IUP) modification submitted by the City of Greensboro for the following Significant Industrial
User (SIU). The IUP was received by the Division on 03/08/2022.
SIU #
SIU NAME
P049
CHEMOL COMPANY, INC.
The review indicates that the IUP is adequate and meets 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.
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.
