Subject: Notice of Violation
Compliance Evaluation Inspection
NOV-2020-PC-0087
City of Kings Mountain
NPDES Permit No. NCO020737
Cleveland County
Dear Mr. Duncan:
Enclosed is a copy of the Compliance Evaluation Inspection report for the inspection
conducted at the subject facility on January 28, 2020 by Ori Tuvia. The cooperation of Richelle
Meek and Kathy Moses during the site visit was much appreciated. Please advise the staff involved
with this NPDES Permit by forwarding a copy of the enclosed report.
Overall, the site is much improved. Previously noted lab issues had been addressed as
well as the short-circuiting observed in clarifier #4 due to an uneven weir. The purchase of new
SCADA system is also a welcomed forward step.
The following areas of concern noted in prior inspection reports require your attention:
1. The weir in clarifier #3 showed signs of rusting. The ORC did indicate that the coming
year's budget will include resources to repair the clarifier.
2. Dead spots were observed in all three (3) aeration basins, especially in aeration basin #1.
Mixers, in addition to the existing diffusers, would potentially eliminate the observed dead
spots. A plan to improve aeration and eliminate the dead spots is needed.

An additional concern observed during the inspection was that grit was observed in
downstream treatment units including the chlorine contact chamber. A grit removal system would
greatly improve treatment efficiency and significantly reduce the accumulation of grit in other
treatment units.
The report should be self-explanatory; however, should you have any questions concerning
this report, please do not hesitate to contact Ori Tuvia at [phone], or at

Sincerely,
