Waste screening records were observed for June 2019 through December 2020. 12. The facility maintains semiannual groundwater and surface water monitoring and leachate test records submitted by SCS Engineers, P.C. and analyzed by Pace Analytical out of Huntersville, North Carolina. Records were observed for groundwater and surface water monitoring and leachate testing conducted on May 30, 2019, and

An additional sampling was conducted in November of 2020 and the report shall be submitted to the Solid Waste Section within 120 days of the sampling event. A-1
Sandrock, Inc. shall ensure that all sampling is conducted as required. The failure to monitor could have resulted in harm to public health or the environment.
13. The facility conducts landfill gas monitoring via twelve gas monitoring wells. Wells are located around the C&D landfill footprint. No building interiors are sampled as part of the landfill gas monitoring requirements due to a
creek separating the landfill footprint from any structures at this facility. Sampling is conducted on site by Pace Analytical. Records were observed for 2019 and 2020. No exceedances were recorded.
14. The facility maintains a record of the amount of material received. The amount of C&D received for disposal from January 1, 2020 through December 31, 2020 is 98,263 tons. Tonnage of concrete received during that time was 9,527 tons with 5,917 tons recovered. Tonnage of LCID received during that time 1997 tons with 1467 tons of LCID recovered during the same. 15. The facility maintains a weekly soil cover log. Records were observed for May 8, 2019 through December 31, 2020. 16. The facility annual report (FAR) was received by the SWS dated July 9, 2020.
