Dear Mr. Greer:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment
Permit (IUP) modifications submitted by the City of Salisbury for the following Significant Industrial
Users (SIUs). The IUPs were received by the Division on April 20, 2022.
SIU #
SIU NAME
0002
Nouryon Surface Chemistry, LLC
0034
Thorneburg Hosiery Mills, Inc.
0007
Freirich Foods
0026
Hitachi Metals, Ltd. of North Carolina
0038
Innospec Performance Chemicals
The review indicates that the IUPs are adequate and meets 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.
