DANIEL SMITH vhvc w NORTH CAPOLINA Emir+ronmemaf Qrsoltiry February 18, 2020 Ms. Stephanie Scheringer, Division Manager Two Rivers Utilities P.O. Box 1748 Gastonia, NC 28053 Subject: Compliance Sampling Inspection Eagle Road WWTP NPDES Permit No. NC0006033 Gaston County Dear Ms. Scheringer: Enclosed is a copy of the Compliance Evaluation Inspection for the inspection conducted at the subject facility on February 11, 2020, by Ori Tuvia and Maria Schutte. David Shellenbarger's, Kevin Greave's, and Hubert Hampton's cooperation 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 facility should continue to investigate a plan to prevent floodwater from the river from backing through the effluent pipe into the chlorine contact basins, and potentially the secondary clarifiers at the plant. At the time of the inspection split samples were taken. The results will be sent at a later date when they have been returned from the lab. The report should be self-explanatory; however, should you have any questions, please do not hesitate to contact Ori Tuvia at (704) 235-2190, or at ori.tuvia(kncdenr.gov. cc: NPDES, MRO files (Laserfiche) Sincerely, CDocuSigned by: �y.0� H P44rft for F161 FB69A2D84A3...
