Dear Mr. Lewallen:
On May 13, 2022' a Pretreatment Compliance Inspection (PCI) was performed by Jim Gonsiewski
of the Winston-Salem Regional Office. You were present for the inspection along with Ms. Lisa
Osthues, Pretreatment Coordinator for the Town of Ramseur. The purpose of this inspection was
to determine the effectiveness of the Town'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 0.48 MGD permitted facility. The City has one (1) Significant Industrial User (SIU) which
is categorical. The publicly owned treatment works (POTW) has not had any limits violations since
the last pretreatment compliance inspection.
POTW Interview
There are no plant problems related to pretreatment issues and there are no NPDES permit limit or
monitoring violations recorded from September 2021 through April 2022. The facility is very
well operated.

approved on February 8, 2018. The next HWA was due on October 1, 2022, but an extension was
granted to May 15, 2023.

FILE REVIEW COMMENTS: A very well run pretreatment program. In the headworks analysis, it appears that the facility is
over allocated for silver. This is due to the sample having been tested previously with a PQL higher than 0.001 mg/L. This will be
resolved in the next headworks analysis.
