Dear Mr. Lewallen:
On September 10, 2021 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 March 2020 through August 2021. The facility is very well
operated.
Pretreatment Program Elements Review
The Headworks Analysis (HWA) renewal was submitted on December 20, 2017. The HWA was
approved on February 8, 2018. The next HWA is due on October 1, 2022.
The last Industrial Waste Survey (IWS) was submitted on April 1, 2021. The IWS was approved
on May 5, 2021. The next IWS is due on April 1, 2026.
