W. Pritchett NOV 2018 L. W. Pritchett Jr.,Inc. Water Resources 2410 Roswell Ave#404 Permitting Section Charlotte,NC 28209 SUBJECT: Compliance Evaluation Inspection Report Former T&G Site Certificate of Coverage NCG510536 under NPDES General Permit NCG510000 Alamance County Dear Mr. Pritchett: On October 18, 2018, Paul DiMatteo of this office met with Danny Oldham, Remediation Technician/Site Supervisor for Pyramid Environmental to perform a Compliance Evaluation Inspection on the subject wastewater treatment facility. This type of inspection consists of two basic parts: a file review and an on-site inspection of the treatment facility. The attached inspection form notes the areas that were evaluated for this inspection.Notable findings are outlined as follows. 1. Lab reports provided by Pyramid Environmental indicated that the detection limit for lead analysis was 4.4µg/l. However, the final effluent limit for lead is 3 tg/l. The Permit requires that, if a sufficiently sensitive analysis method is available,then the analysis"must produce minimum detection and reporting levels that are below the permit discharge requirements and all data generated must be reported down to the minimum detection or lower reporting level of the procedure."Please take care to ensure that lead analysis is performed with a sufficiently sensitive method. Please note that the Permit also requires that if the final effluent limit for lead is exceeded then quarterly hardness sampling must also be conducted. If you have any questions regarding the inspection or this report, please contact Paul DiMatteo at(336) 776-9691 or me at(336) 776-9800. Sincerely,yr— (I' • (6 Sherri V.Knight,P.E.

Note, the Certificate of Coverage required 3 days notice before beginning operation, but it does not appear that this office conducted a pre-operational inspection. This system consists of soil venting extraction (SVE), pumps, filters, oil-water separator, EZ-Tray QED Stripper, sock filter, aggregate filter, carbon filter, and discharge. While reviewing monitoring data, I noted that the detection limit for lead was reported to be 4.4 ug/I. Permittee must ensure that their lab is able to detect down to the parameter's final limit of 3 ug/I.
