INFerINDONC <br /> the soil, it is proposed to subdivide the stockpile into five areas f <br />' kp o approximately 100 cubic <br /> yards Within each area four sampling locations will be determined based on a gid pattern, <br /> see Figure 5 At each location, soil samples will be collected at various depths to obtain a <br /> valid representation throughout the soil stockpile The soil samples collected from each <br />' location will composited in the f eld During all soil sampling, field headspace analysis <br /> will also be conducted in order to verify that representative samples are being collected Soil <br />' sampling and field headspace analysis will be conducted according to Versaz's sampling <br /> protocol as outlined in Appendix B The 20 composite soil samples from the sampling <br /> locations will be submitted to a certified laboratory At the laboratory, the 20 samples will be <br /> composited into one sample per 100 cubic yard area Following composrting, the five soil <br /> samples will be analyzed for TPH-G, BTEX and TPH as jet fuel --IAOb <br /> Upon receipt of the analytical results, Versar will forward a copy to the San Joaquin <br /> rPHS/EHD for their review Following their review, Versar will if necessary, negotiate with <br /> San Joaquin PHS/EHD to determine what soil can remain on site and what may require <br />'. additional treatment or disposed of at an off-site facility It is proposing to spread any soil <br /> containing concentration less than 100 mg/kg�TPamnd the absence of BTEX compounds OX <br />' on the open ground where the soil stockpile is presently located Soil that cannot be spread Ca.a. <br /> on site will either be treated on soil or be disposed of at an appropriately licensed disposal or < <br /> recycling facility 1APICIL <br /> I3 4 2 Soil Stockpile 2 <br /> Soil Stockpile 2 was generated during removal and excavation activities at the wash <br />' pad area in 1992 an during the installation of the present 15,000 gallon fuel storage tank at <br /> the site The stockpile consists of approximately 1,250 cubic yards of soil, covering an area <br /> of approximately 6,700 square feet at an average of five feet in height Based on the source <br /> of the soil and previous sampling events, soil stoc ile 2 led The stockpile <br /> was sampled in July 1992 by Golden West Environmental Services (Golden West) Golden <br /> West collected 24 samples, which were composited into six soil samples and analyzed for <br /> TPH-G The analytical results of the soil sample analyses indicated the highest concentration <br /> 10 <br /> i <br />
