I <br /> Page 4 <br /> Stockpile samples SP - la-b through SP - 6a-b. each represent <br /> approximately 50 cubic yards . Two samples were collected <br /> for every 50 cubic yards . Two samples were then composited <br /> in the laboratory and analyzed as one sample representing <br /> approximately 50 cubic yards . <br /> Stockpile soil samples were collected by removing the top 12 <br /> to 16 inches of soil , pushing a clean 6 " long ( 2 " diameter ) <br /> brass tube into the stockpile until completely filled , then <br /> removed , sealed and handled as described previously . <br /> ANALYTICAL RESULTS <br /> Summaries of the soil analytical results are presented in <br /> Tables A and B . The fuel UST excavation and trench samples <br /> were analyzed for Total Petroleum Hydrocarbons <br /> calculated as gasoline ( TPH-Gasoline ) according to EPA <br /> Method 8015 ( Modified ) , Benzene , Toluene , Ethylbenzene , and <br /> Xylenes ( BTEX ) according to EPA Method 8020 and Total Lead <br /> according to EPA Method 7420 . Additional analyses for the <br /> samples from the waste oil tank and sump excavations and <br /> associated stockpiles consisted of Total Oil and Grease <br /> ( TOG ) according to EPA Method 5520F , ICAP Metals , CAM 17 <br /> Metals , Volatile Organic Compounds ( VOCs ) according to EPA <br /> Method 8010 and Priority Organic Pollutants according to EPA <br /> Method 8270 . Samples collected from the hoists and were <br /> f analyzed for TOG . <br /> i <br /> Copies of the Certified Analytical Reports ( CABs ) from the <br /> Laboratory and Chain - of - Custody forms are attached in <br /> Appendix A . <br /> STOCKPILE DISPOSITION <br /> i <br /> The soil stockpile generated from the waste oil tank and <br /> sump removal will be profiled for disposal at Browning- <br /> Ferris Industries ( BFI ) located in Livermore , California . <br /> The soil stockpile generated from the fuel UST and piping <br /> removal will be aerated and resampled for reuse as on site <br /> backfill material . <br /> i <br /> r <br />
