Box 429 - Kings Mountain, NC28086 Subject: Notice of Violation Compliance Evaluation Inspection NOV-2017-PC-0250 City of Kings Mountain NPDES Permit No. NCO020737 Cleveland County Dear Mr. Duncan: Enclosed is a copy of the Compliance Evaluation Inspection report for theinspection conducted at the subject facility on April 7, 2017, 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. The main area of concern observed during the inspection was that a review of Chain of Custody forms revealed that regular_ sampling of the effluent discharge for process control was being conducted from May 2016 through February 2017 without having been reported on the Discharge Monitoring Reports (DMR). The Operator in Responsible Charge (ORC) was advised that anysampling of the effluent discharge must be conducted in accordance with the conditions of the permit and shall. be reported on the monthly DMR. Amended DMRs for the period of May 2016 through February 2017 have been submitted. The amended datafor the month of August 2016 yielded ai onthly average Thallium result of 72.5 ug/l. This result is a violation of the Special Order by. Consent (SOC VQ S 16-001)) for the monthly average limitation for Thallium (60:1 ug/1). This SOC `violation will be handled via separate correspondence from the Division. An additional area of concern was that short-circuiting was observed at the first clarifier due to an uneven weir.
