Subject: Pretreatment Review of Industrial User Pretreatment Permit Drop Request
Program: City of Sanford
WWTP: Big Buffalo WWTP - NPDES #: NC0024147, Lee County
Dear Ms. Jordan:
The Municipal Unit of the Division of Water Resources has reviewed the request to drop the following industry
from the list of significant industrial users (SIUs) for the City of Sanford's Big Buffalo WWTP (NPDES #:
NC0024147). The SIU drop request was received by the Division on 12/10/2021:
r SIU #
000007
SIU NAME
Magneti Marelli Powertrain USA, LLC
The review indicates that the facility no longer discharges process wastewater and thus no longer meets the
definition of a SIU. Therefore, the SIU drop request is approved based on compliance with 15A NCAC 2H
.0907(b). The SIU list which is part of your approved pretreatment program is hereby modified.
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:
[e-mail]] Thank you for your continued support of the Pretreatment Program.
