SUBJECT: Pretreatment Audit Inspection
Town of Mocksville
NPDES Permit No. NC 0021491
Davie County
Dear Mr. Powers:
On June 23, 2021, a Pretreatment Audit Inspection (PAI) was performed by Alex Lowe of the
Division of Water Resources Winston-Salem Regional Office. Mr. Josh Powers, Mr. Todd
Robinson, and Ms. Madelyn Mills were all present and instrumental in providing the requested
information for the inspection.
The purpose of this inspection was to determine the effectiveness of the permitted pretreatment
program, which includes reviewing SIU permit files, POTW plant performance, SIU monitoring
data, and observing an on -site SIU inspection by POTW personnel.
No violations were uncovered during this audit. It was noted that some program documentation
was outdated, with the latest approval letter for the IWS and ERP absent from the files. After some
review of the Division correspondence, it is likely that these files, which were sent digitally, were
never passed along by the previous pretreatment coordinator. Digital copies of these files were
sent to Ms. Madelyn Mills on 06/23/2021. If it has not been done already, please print these
Division approval letters and file them with the latest copies of your IWS and ERP to ensure your
documentation is up-to-date for any future inspections.
