SUBJECT: Pretreatment Audit Inspection (PAI)
Town of Ramseur
NPDES# NCO026565
Randolph County
Dear Mr. Cheek:
On February 4, 2020 a Pretreatment Audit Inspection (PAI) was performed by Jim Gonsiewski of
the Winston-Salem Regional office. Ms. Nadine Blackwell, pretreatment coordinator for the Town
of Ramseur was present along with Mr. Terry Lewallen, ORC for the facility. 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 MatLab facility was conducted in conjunction with an inspection by the Town of Ramseur.
Background
This is a 0.48 MGD permitted facility. The City has one (1) Significant Industrial User which is
also a Categorical Industrial User. The SIU (MatLab) was in Significant Non Compliance (SNC)
for the first six (6) months of 2019. A $750 penalty was assessed against MatLab.
Pretreatment Program Element Review
The Headworks Analysis (HWA) was submitted on December 20, 2017. The HWA was approved
on February 8, 2018. The next HWA is due on October 1, 2022.
The Industrial Waste Survey (IWS) was submitted on January 15, 2016. The IWS was approved
on March 7, 2016. The next IWS is due on April 1, 2021.
The Sewer Use Ordinance (SUO) was approved on October 2, 2015.
The Enforcement Response Plan (ERP) was approved on October 2, 2015.

STMP File Review
The Short Term Monitoring Plan (STMP) was approved on October 2, 2015 and is being conducted
at the proper locations and frequencies.
Industrial User Permit (IUP) File Review
A review of the file for Matlab (#0002) revealed that the monitoring data was well organized and
compliant.
The slug control plan for MatLab (#0002) was in good order.
Action Items
No other action items were noted.
The pretreatment program is considered satisfactory. Ms. Blackwell maintains an excellent
program. If you have any questions please contact Jim Gonsiewski or me at [phone].
Sincerely,
