DANIEL SMITH Director Joseph Williams Norfolk Southern Railway Company 1200 Peachtree St NE Augusta, GA 30909 NORTH CAROLINA Environmental Quality February 11, 2020 Subject: Compliance Evaluation Inspection Report NPDES Permit NCO029246 Linwood Yard WWTP, Davidson County Dear Mr. Williams: On January 30, 2020, Paul DiMatteo of the Division of Water Resources (Division), Winston- Salem Regional Office met with Leonard Stogner, Operator in Responsible Charge (ORC), to conduct a Compliance Evaluation Inspection of the above referenced wastewater treatment plant. This inspection consists of (1) a review of the permit and accompanying documentation to determine compliance with permit conditions, and (2) an on -site inspection of several collection system components. The attached inspection form notes the areas that were evaluated for the inspection, with any notable findings outlined as follows. Item of Concern — The Inspector noted one instance of an effluent analysis being conducted but not reported on the DMR. In August 2019, the lab reported an Ammonia result of 0.28 mg/l, but this was not on the DMR. Operators said that the lab may have run the analysis inadvertently. The Inspector discussed proper reporting requirements with the operators. If you have any questions concerning this report please contact Paul DiMatteo at (336) 776-9691 or Lon Snider at (336) 776-9800. Sincerely, EDocuSigned by: �� -T sMacr 145B49E225C94EA... Lon T.
