«., Work Plan for Refined Plume Definition and Management of Floating Product-7500 W 11th St., Tracy, CA. Page.32 <br /> operated by a drilling contractor holding a C57 license issued by the California Contractors <br /> State License Board. A California-licensed geotechnical engineer will log the borings. <br /> .,. While the borings for the proposed LNAPL monitoring wells are being advanced, soil <br /> samples in a continuous plastic liner by cutting an approximate 6-in length of the liner so as <br /> to retain discrete samples from the subsurface at 5-ft. intervals. However, the engineer may <br /> direct additional or alternate samples to be obtained if the conditions revealed by the boring <br /> indicate such to be appropriate. <br /> Following sample recovery, each sample liner will be cleaned externally, its ends covered <br /> with Teflon foil and closed with tightly-fitted plastic caps secured with adhesiveless tape. <br /> Each sample tube will then be labeled for identification, entered into chain-of-custody <br /> �- control and packed on chemical ice for transport to STL's laboratory in Pleasanton Califomia <br /> within 24 hours. <br /> ik- Each soil sample submitted to the laboratory will be analyzed for the following suite of <br /> analytes. <br /> Anal3qe Method of Anal <br /> Total Petroleum Hydrocarbons EPA Method 5030/8015 <br /> (quantified as Diesel) <br /> Total Petroleum Hydrocarbons EPA Method 8020A/8015 <br /> (quantified as Gasoline) <br /> Benzene EPA Method 8020 <br /> Toluene EPA Method 8020 <br /> Ethyl benzene EPA Method 8020 �_` c k <br /> 1, 6 <br /> Total Xylene Isomers EPA Method 8020 <br /> STL's laboratory is certified by the DHS to perform the soil analyses listed above. <br /> 8.3 Disposal of Drill Cuttings <br /> Drill cuttings from the LNAPL monitoring well borings will be retained in 55-gal., close- <br /> topped, steel drums. When full, the drums will be closed and placed in storage on the 7500 <br /> West Eleventh Street property until the results of analyses of soil and water samples are <br /> available. When the analytical results are obtained, the soil in the drums will be classified <br /> and, if clean, disposed as clean fill on the 7500 West Eleventh Street property. Soil affected <br /> by components of fuel hydrocarbons will be loaded into a truck and shipped for disposal at <br /> the Forward Landfill, a Class II disposal facility in Manteca, California. <br /> sic <br />
