Salem Regional Office conducted a Pretreatment Audit Inspection at the above referenced wastewater
treatment system. Mr.Justin Shell, Pretreatment Coordinator, and Mr. Scott Pyrtle, WWTP ORC, were present
for the inspection. The purpose of this inspection was to determine the effectiveness of the Town's
pretreatment program,which included: a detailed file review, review of the POTW facility performance,
sampling and compliance judgement program, adherence to the enforcement response plan (ERP), and
observing an industrial user inspection.
Background

categorically regulated under 40 CFR Part 433 (metal finishing).

organized and compliant. However, a copy of the industry's most recent IUP application was not available
during the file review. Mr. Shell was able to obtain a copy during the IU inspection.
A review of the file for Johnston Casuals, Inc. (#0002) revealed that the monitoring data was well
organized and compliant.
The slug control plans for these industries were in good order.

Town of North Wilkesboro

NPDES #: NC0020761
Dear Mr. Foster:
The Pretreatment Unit has reviewed the Enforcement Response Plan (ERP) submitted by the
Town of North Wilkesboro. This ERP was received by the Division on November 17, 2003.
The review indicates that the ERP is adequate and the minimum requirements of 15A NCAC
2H 0900 and 40 CFR 403 are met. Proper implementation of an Enforcement Response Plan is
also required by Part III (B), of your NPDES permit. Please refer to the Comprehensive
Guidance for North Carolina Pretreatment Programs for additional information and examples
The Town Board of Commissioners approved the ERP on November 6, 2003.
During the review it was noted that Section 5.0 is a repeat of Section 4.0.
Thank you for your continued cooperation with the pretreatment program. If you have any
questions or comments, please contact Deborah Gore of the Pretreatment Unit at 733-5083, ext.
593, [email: [e-mail]].
Sincerely,
