Dear Mr. Freeman:
On June 14, 2019 a Pretreatment Compliance Inspection (PCI) was performed by Jim Gonsiewski
of the Winston-Salem Regional Office. Mr. Joel Freeman was present for the inspection. The
purpose of this inspection was to determine the effectiveness of the City's pretreatment program,
which includes reviewing the files, POTW plant performance, industry monitoring data, and
adherence to the enforcement response plan (ERP).
Background
This is a 51 MGD permitted facility with the Archie Elledge and Muddy Creek facilities. The City
has twenty seven (27) Significant Industrial Users (SIUs) of which ten (10) are categorical. One
SIU (Kaba-Ilco) closed. The last discharge from this facility occurred on May 10, 2019.
POTW Interview
There are no plant problems related to pretreatment issues from June 2018 through May 2019. The
Muddy Creek facility had NPDES violations for pH in June and October 2018 and flow in
December 2018. No other NPDES permit limit or monitoring violations were recorded during this
period. The facility is very well operated.
