AWA destroyed all three-wells by over-drilling the boreholes and casings with a CME-75 truck- mounted drilling rig and 8-inch diameter hollow-stem augers. AWA removed the street boxes and all well casing materials, drilled out the annular seals and filter packs, and filled the L boreholes with neat cement grout, placed to the bottoms of the boreholes with a tremie pipe. As a condition of the encroachment permit, Ramage Environmental contracted with Aggressive Concrete Cutting (Contractors License #810068) to saw-cut and hot asphalt patch the surface locations. Aggressive Concrete Cutting saw-cut two-foot by two-foot square areas around the cement-filled boreholes, and then compacted hot asphalt flush to surface grade at each of the three former well locations. I On September 24, 2008, on behalf of AWA, Ramage Environmental submitted well.completion 4 reports documenting the well destructions to the California Department of Water Resources r (DWR). Copies of the well completion reports for the well destructions are included i,n Appendix E 3.3 Disposal of Waste Well Materials and Soil AWA contained the waste well materials and soil in one 55-gallon drum for temporary on-site storage pending waste characterization and proper disposition. Following the well destructions on November 7, 2008, to characterize the waste material, Ramage Environmental collected one representative soil samples. Ramage Environmental transported the soil sample with chain of- custody documentation to Kiff Analytical, LLC (Kiff), a state of California certified hazardous waste testing laboratory (Certification #2236). Kiff analyzed the sample for TPH-as-diesel by EPA Method 8015M, TPH-as-gasoline, BTEX and MTBE by EPA Method 8260B, and for total lead by EPA Method 60106. I The soil sample contained 100 milligrams per kilogram (mg/kg) of TPH-as-diesel and 4.4 mg/kg of total lead. On December 1, 2008, based on the analytical results, EnviroPacific transported the drum of waste well materials and soil as non-hazardous waste to Redwood Landfill in Novato, California for disposal under Authorization #PC252. A copy of the non-hazardous soil transport document is included in Appendix D,-and the laboratory report is included in Appendix E. 10
