Subject:
Pretreatment Review of Industrial User Pretreatment Permit Modifications
Program: Town of Mayodan
WWTP: Town of Mayodan WWTP, NPDES #: NC0021873
Rockingham County
Dear Ms. Hopper:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment
Permit (IUP) modifications submitted by the Town of Mayodan for the following Significant Industrial
Users (SIUs). The IUPs were received by the Division on November 31, 2021.
SIU #
SIU NAME
0109
Strum, Ruger & Company
0105
Unifi Manufacturing, Inc.
0108
Sans Technical Fibers, LLC
The review indicates that the IUPs are adequate and meet 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.
