Page 2 <br /> Heating Oil Tank Sampling <br /> Soil sample D-1-9' was collected between 2 and 3 feet beneath the fill end of the <br /> tank at approximately 9 feet below grade (Figure 2). <br /> Stockpile Sampling <br /> Soil stockpiles generated from the removal were sampled prior to backfilling <br /> Four soil samples were collected from each stockpile(Figure 2). The four samples <br /> were composited in the laboratory and analyzed as one sample. These samples <br /> were collected by removing the top 6 to 12 inches of soil, then pushing a sample <br /> tube into the soil until completely full. The samples were sealed, labeled and <br /> handled as mentioned previously in this report. Following the collection of <br /> samples, a layer of visqueen was placed into each excavation and the soil <br /> stockpiles were used as backfill material in the respective excavations. Compos- <br /> ite soil sample designations are SP-1 A-D for the soils generated from the heating <br /> oil tank removal and SP-2 A-D from stockpiles resulting from the waste oil <br /> removal (Figure 2). <br /> ANALYTICAL RESULTS <br /> Summaries of the soil analytical results are presented in Table 1. The heating oil <br /> tank excavation and stockpile samples were analyzed for Petroleum Hydrocar- <br /> bons calculated as Diesel (TPH-Diesel) according to EPA Method 8015 (Modified) <br /> and Benzene,Toluene,Ethylbenzene,and Xylene (BTEX) according to EPA Method <br /> 8020. The samples collected in the former waste oil tank excavation and <br /> stockpile included Total Petroleum Hydrocarbons calculated as Gasoline and <br /> Diesel according to EPA Method 8015 (Modified) and Benzene, Toluene, <br /> Ethylbenzene, and Xylene (BTEX) according to EPA Method 8020, Halogenated <br /> Volatile Organics according to EPA SW-846 Methods 5030/ 8010, Senn-Volatile <br /> Organic Priority Pollutants according to EPA Method 8270, Total Oil and Grease <br /> according to EPA Method 55 20 F, and Polychlorinated Biphenyls (PCB) according <br /> to EPA Method 8080. <br />
