Subject: Pretreatment Review of Industrial User Pretreatment Permit Renewal
Program: Franklin County Public Utilities
Wastewater Treatment Plant: Franklin County WWTP
NPDES #: NC0069311, Franklin County

Dear Paul Langfield:

The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
renewal submitted by Franklin County, Franklin County WWTP (NC0069311) for the following Significant
Industrial User (SIU). The submission was received by the Division on 10/31/2023.
IUP # SIU NAME
0112 Novozymes NA, Inc. (NZNA)
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 Headworks Analysis and Allocation Table presently indicate overallocation for TN, TP, CN, Ag and Hg,
however the Division considers this document to be inadequate to represent the present conditions for the POTW.
The Division requests that Franklin County Public Utilities update its Headworks Analysis, Allocation Table, and
Short Term Monitoring Plan using the data from 2022, and resubmit for review by 03/31/2024.
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.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
please contact Natalie Gorensek [email: [e-mail] ] at [phone] or Octavio Henriquez at
[phone] [email: [e-mail]].
