Subject: Pretreatment Review of Industrial User Permit Modification
Program: City of Wilson

Wilson County
Dear Laura Pruitt:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit
(IUP) modification submitted by the City of Wilson for the following Significant Industrial User (SIU). The IUP
modification was received by the Division on December 1, 2020.
IUP # SIU NAME
2000-025 Eon Labs, Inc
The review indicates that the IUP is adequate and meets the minimum requirements of 15A NCAC 211.0905 -
.0916 and 40 CFR 403.8(fl(1)(iii). The IUP was modified to increase the monthly average flow limit from 5000
gpd to 12,000 gpd, add NO2, NO3, and TKN to semi-annual monitoring requirements, add certification laboratory
requirements, and change detection limits for silver and lead.
Regardless of this approval action today, within 180 days of the effective date of any reissued/modified NPDES
permit, the Permittee would be required to submit to the Division a written technical evaluation of the need to revise
local limits.
Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control
and document the wastewater discharge from SIUs 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 Diana Yitbarek at 919-707-9130 [email:
diana.yitbarekkncdenr.gov]. Thank you for your continued support of the Pretreatment Program.
Sincerely,
