Subject: Pretreatment Review of Industrial User Pretreatment Permit Modification
Program: City of Greensboro
Wastewater Treatment Plant: T.Z. Osborne Water Reclamation Facility
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
submission was received by the Division on January 9th, 2024.

IUP # SIU NAME
P033 GILBARCO, INC

The review indicates that the IUP is adequate and meets 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 the 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 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 Octavio Henriquez at [phone] [email:
[e-mail]]. Thank you for your continued support of the Pretreatment Program.
