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. The findings and observations are outlined as follows. I. Permit The general permit became effective on October 1, 2016 and will expire on September 30, 2020. A copy of the current permit was available during the inspection. II. Self-Monitoring Program The general permit no longer requires submittal of discharge monitoring reports.Monitoring data obtained from October 2016 through July 2018 was reviewed during the inspection. It appeared that monitoring was being conducted at the location and frequencies specified by the permit.pH is measured in the field by Mr. Byers; other analysis is conducted by Con-Test Analytical under certification #652. A summary of identified permit limit exceedances follows: DE Q is) NORTH CAROLINA ueoaMient al fmtramnental arakty North Carolina Department of Environmental Quality I Division of Water Resources Winston-Salem Regional Office 1450 Hanes Mill Road,Suite 300 I Winston-Salem,North Carolina 27103 336.776.9800 NCG510522, Circle K Stores 9/19/2018 Parameter Permit Limit Month of Exceedance Value (µg/1) MTBE 19 µg/1 2/2017 34 (phase 1) Lead (final limit) 3 µg/1 2/2017 3.5 (phase 1) (Note: interim limit is 25 µ,g/1 until October 1, 2020.

Records/Reports Copies of DMRs, operator visitation logs, operation sheets, lab reports and chain-of-custody forms were available for review during the inspection. Lab data is maintained according to the permit. IV. Flow Measurement Effluent flow is measured using a 1-inch Neptune T-10 residential flow meter. Mr.Byers said they replace the meter yearly to serve as their calibration. Records of the replacement were available for review. V. Operations and Maintenance The plant is operated as required. The facility appeared to be well operated and managed. VI. Facility Site Review The site includes two groundwater remediation systems consisting of influent pumps,oil-water separators, air strippers, filters and activated carbon. No concerns were noted during the inspection. The compliance evaluation inspection is satisfactory. 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, Sherri V. Knight, P.E.

He brought binders filled with process control data and lab reports for monitoring conducted during the past 3 years.There are 2 phases to this system. Phase 1 is next to the Kangaroo convenience store,with a discharge at a small ditch on the other side of the store. Phase 2 is behind a house across the street,with a discharge into the same ditch. Both systems consist of pumps, oil-water separators, air strippers, filters, activated carbon, and discharge. Effluent samples are taken from a sampling line before discharge.
