Dear Mr. Patterson:
On August 26, 2020 a Pretreatment Audit Inspection (PAI) was performed by Jim Gonsiewski of
the Winston-Salem Regional office. Ms. Kristy King, industrial pretreatment specialist for the
City of Burlington, was present. The purpose of this inspection was to determine the effectiveness
of the pretreatment program, which included: a detailed file review, review of the POTW plant
performance, sampling, and compliance judgement program, and adherence to the enforcement
response plan (ERP). Additionally, an inspection of the Indulor facility was conducted in
conjunction with an inspection by the City of Burlington.
