Dear Ms. Jordan:
The Municipal Unit of the Division of Water Resources has reviewed the following Industrial User
Pretreatment Permits (IUPs) with modifications submitted by the City of Sanford for Significant Industrial
Users (SIUs). The IUP modifications were received by the Division on 03/21/2022.

The review indicates that the IUPs are adequate and meeting the minimum requirements of 15A NCAC
2H .0905 and .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table, maintained in the Division's database,
has been updated accordingly.
Regardless of this approval action today, within 180 days of the effective date of any reissued NPDES
permit (or any subsequent NPDES permit modification) 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 (SIU's).

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 Keyes McGee at [phone] [email:
