Subject: Pretreatment Review of Industrial User Pretreatment Permit Modification
Program: Town of Mayodan
Wastewater Treatment Plant: Town of Mayodan WWTP,
NPDES#NC0021873,Rockingham County
Dear Nadine Blackwell:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit(IUP)
modification submitted by the Town of Mayodan(NC0021873)for the following Significant Industrial User(SIU).
The submission was received by the Division on 06/26/2024.
SIU# SIU NAME
0109 STURM,RUGER&COMPANY
The Division's 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 allocation table, maintained in the Division's database, has been updated
accordingly.
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 Keyes McGee at(919) 707-3626 [email: keyes.mcgeegdeq.nc.gov].
Sincerely,
