Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On December 17, 2020 a Pretreatment Compliance Inspection (PCI) was performed by Jim
Gonsiewski and Alex Lowe of the Winston-Salem Regional Office. Mr. Troy Branch was present for the
inspection. 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).
The pretreatment program at the facility is compliant and very well run. There were NPDES limit
exceedances for dichlorobromomethane in December 2019, March 2020, and July 2020. The POTW
has been working on a solution to eliminate these exceedances.
