Dear Mr. Lambert:
On September 2, 2020 a Pretreatment Compliance Inspection (PCI) was performed by Jim
Gonsiewski and Alex Lowe of the Winston-Salem Regional Office. Mr. John Grey and Mr.
Michael Weir were present for the inspection. The purpose of this inspection was to determine the
effectiveness of the County'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 1.5 MGD facility. The County has one (1) Significant Industrial User (SIU), Ingersoll
Rand, which is not categorical.
POTW Interview
There are no plant problems related to pretreatment issues. The facility is very well operated.
Pretreatment Program Elements Review
The Headworks Analysis (HWA) renewal was submitted on October 3, 2016. The HWA was
approved on March 3, 2017. The next HWA is due on September 30, 2021.
The last Industrial Waste Survey (IWS) was submitted on May 29, 2020. The IWS was approved
on August 25, 2020. The next IWS is due on April 30, 2025.

and compliant.
The slug control plan for Ingersoll Rand (#004) was in good order.
