SUBJECT: Pretreatment Compliance Inspection (PCI)
City of Mebane
NPDES# NCO021474
Alamance County
Dear Ms. Varinoski:
On July 25, 2019 a Pretreatment Compliance Inspection (PCI) was performed by Jim Gonsiewski and
Michael Meilinger of the Winston-Salem Regional Office. Ms. Amy Varinoski 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).
Background
This is a 2.5 MGD permitted facility. The City has five (5) Significant Industrial Users (SlUs), three (3) of
which are categorical. The publicly owned treatment works (POTW) had exceedances of BOD and
ammonia in 2018 due to hydraulic issues caused by the weather (heavy rain and cold temperatures) and an
exceedance of toxicity, possibly due to a clarifier coating.
POTW Interview
There are no plant problems related to pretreatment issues and, other than BOD, Ammonia, and Toxicity,
there are no NPDES permit limit or monitoring violations recorded from January 2018 through December
2018. The facility is very well operated.
Pretreatment Program Elements Review
The Headworks Analysis (HWA) renewal was submitted on March 24, 2016. The HWA was approved on
June 3, 2016. The next HWA is due on March 31, 2021.
The last Industrial Waste Survey (IWS) was submitted on January 4, 2016. The IWS was approved on
March 7, 2016. The next IWS is due on December 1, 2020.
