0 0 <br />After the soil samples were collected, the ends of the sample tubes were covered with Teflon tape <br />and capped. The soil samples were then appropriately labeled, placed in a cooler with ice, and <br />transported under chain -of -custody protocol to the analytical laboratory. Copies of the chain of <br />custody are included in Appendix E. <br />2.3 Sample Analyses <br />The samples were transported and submitted to McCampbell Analytical, Inc., an ELAP-certified <br />laboratory located in Pacheco, California. The samples were analyzed for total petroleum <br />hydrocarbons as diesel (TPH-D) under EPA method 8015 (modified). The samples were further <br />analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEC constituents under EPA <br />Method 8021B and methyl tertiary butyl ether (MTBE) under EPA Method 8260B. <br />2.4 Soil Sample Analytical Results <br />TPH-D was detected in sample CS (01-04), collected from the soil stockpile, at a concentration <br />of 61 parts per million (ppm). Soil stockpile sample CS (01-04) also contained xylenes at a <br />concentration of 0.030 ppm. No other analytes were detected in any of the remaining soil <br />samples. Soil sample analytical results are summarized in Table 1 and depicted in Figure 3. <br />Copies of the laboratory analytical reports are included in Appendix E. <br />f <br />The approximately 62 tons of excavated soil was transported to Forward Landfill in Manteca, <br />California for disposal. Copies of the non -hazardous waste manifests are included in <br />Appendix F. <br />4e0 UST Installation Activities <br />Gettler-Ryan installed a new 1,000 -gallon double -walled steel with fiberglass coating UST in the <br />same excavation as the former UST. The UST contains diesel fuel for the emergency backup <br />generator. UST installation activities were conducted by Gettler-Ryan personnel independent of <br />Shaw oversight. <br />ICNCD\O:SHARE\USnO4-M7.doc 3 <br />11 <br />
