Subject: Pretreatment Review of Industrial User Pretreatment Permit Modifications
Program: City of Greensboro
WWTP: T.Z. Osborne WWTP, NPDES #: NCO047384
Guilford County
Dear Mr. Skee:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment
Permit (IUP) modifications submitted by the City of Greensboro for the following Significant Industrial
Users (SIUs). The ]UPS were received by the Division on August 28, 2020.
SIU #
SIU NAME
P025
Lanxess Corporation
P049
Chemol Company, Inc.
P002
Vertellus Performance Materials Inc.
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 HWA 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.
