Subject: Pretreatment Review of Industrial User Pretreatment Permit (IUP) Drop
Municipal NPDES Permittee: City of Wilson
Treatment Facility: Hominy Creek Water Reclamation Facility
NPDES #: NC0023906, Wilson County

Dear Ms. Pruitt:

The Municipal Unit of the Division of Water Resources has reviewed the IUP drop request submitted by the City of
Wilson for the following- Significant Industrial User (SIU). The submission was received April 25, 2024.

IUP # SIU Name
2000-025 Eon Labs, Inc.

The review indicates that the IUP has been dropped by the City of Wilson Pretreatment Program and the
documentation 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.

Within 180 days of the effective date of any reissued or modified wastewater treatment facility 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 SIUs. Pursuant to 15A NCAC 02H .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.

Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
please contact Keyes McGee at 919 707-3626 / [e-mail].
