-,�M'sm <br /> , <br /> The stockpile samples were delivered to Mohile for chemical analyses, A Chain-of-Custody <br /> was maintained for all samples. Mobile combined each set of four samples into one <br /> composite sample for analysis. All composite samples were then analyzed for TPI-1-G by <br /> USEPA Method 8()15 and 13'1'1aX by U:SEPA Method 8020. Table 3 summarizes the <br /> laboratory analytical data for these samples. 1 aboratory analytical reports are included in <br /> Appendix B and Chain-of-Custody documentation forms are included in Appendix C. <br /> 5.2 Aeration and Disposal of Stockpiled Soil <br /> Disposal options for each soil stockpile were evaluated following receipt of laboratory <br /> analytical data. On November 28, 1990, all stockpiled soil containing less than 100 mg/kg <br /> (ppm) TPH-G was removed from the Site by Dillard Trucking, Inc. of Byron, California <br /> (Dillard) and transported by Dillard to BFI's Class III landfill in Livermore, California for <br /> disposal. <br /> Stockpiled soil contai n i ng TPH-G concentrations greater than 100 mg/kg was aerated at the <br /> Site following receipt of approval by the San Joaquin County Air Pollution Control District. <br /> Aeration began on December 6, 1990, and was completed on February 15, 1991. Dillard <br /> personnel aerated the stockpiled soil at a maximum rate of 49 cubic yards per day. <br /> After aeration was completed, composite samples were collected by Roux and analyzed in <br /> the same manner described in Section 5.1, except that four samples were collected from <br /> each 49 cubic yards of aerated soil. After laboratory analyses indicated a stockpile was <br /> reduced by aeration to less than 100 mg/kg, the soil was transported by Dillard to BFI's <br /> ' S Dor. #AR06776W.I.1 <br /> Roux Assoc:iwr�s <br /> „re <br />
