Subject: Pretreatment Review of Industrial User Pretreatment Permit Drop
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) drop requests submitted by the City of Greensboro for the following Significant Industrial
Users (SIUs). The documentation was received by the Division on October 4th, 2023.

IUP # SIU NAME
P048 HAECO Airframe Services, Inc
P076 Precor Strength

The review indicates the IUPs have been dropped by the City of Greensboro Pretreatment Program and
the documentation meets the minimum requirements of 15A NCAC 2H .0916 and 40 CFR 403.8(f)(1)(iii).
The IUPs issued to the SIUs were allowed to expire without renewal on August 31st, 2023. 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.
