Subject: Pretreatment Review of Industrial User Pretreatment Permit Modification
Program: City of Sanford
Wastewater Treatment Plant: Big Buffalo WWTP
NPDES #: NC0024147, Lee County
Dear Jospeh Lynch:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit (IUP)
modification submitted by the City of Sanford Big Buffalo WWTP (NC0024147) for the following Significant
Industrial User (SIU). The submission was received by the Division on 09/02/2022.
SIU #
SIU NAME
000022
Wyeth, LLC (a Subsidiary of Pfizer)
The review indicates that the IUP is adequate and meeting 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
accordingly.
Regardless of approval action today, 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 Al Woodall [email: [e-mail]] at [phone] or Keyes McGee at [phone]
[email: [e-mail]].
