Dear Mr. Pridgen:
On August 28, 2020, Cheng Zhang of the Raleigh Regional Office conducted a Pretreatment
Compliance Inspection of City of Wilson's pretreatment program. The assistance given by Ms. Laura
Pruitt, the Water Reclamation Compliance Coordinator, was greatly appreciated. The inspection report
is attached. Findings during the inspection were as follows:
1. The City has 11 Significant Industrial Users (SIUs), 9 of which are also Categorical Industrial
Users (CIUs). It was noted that no SIUs were in Significant Non -Compliance (SNC) during the
last two semi-annual periods.
2. The pretreatment inspection file review included Bridgestone (Permit No. 8412), Sun River
(Permit No. 2009-020) and UTC/Kidde (Permit No. 8402). The files needed for review were
available for inspection, contained all the required elements and were in excellent condition. All
three SIUs were compliant during the most recent 6-month period.
A review of the files containing the pretreatment program elements was conducted. All files
were available and up to date. Enforcement Response Plan and Long Term Monitoring Plan were
updated and approved recently.
4. LTMP data were reviewed, it was noted that all parameters were sampled at required locations
and analyzed with required detection levels. LTMP data was well organized and maintained.
