Page 24 <br /> t <br /> engineer will log the borings. <br /> While the borings for the proposed monitoring wells are being drilled, the drilling equipment <br /> will be used to recover soil samples in clean, brass tubes from a depth of 5 ft. in each hole - <br /> and at 5-ft. intervals thereafter, to the bottom of the boring. However, the engineer may direct <br /> 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 tube 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 California <br /> within 24 hours. <br /> Each soil sample submitted to the laboratory will be analyzed for the following suite of <br /> analytes. <br /> Anal to Method of Analvsis <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 <br /> Total Xylene Isomers EPA Method 8020 <br /> STL's Iaboratory is certified by the DHS to perform the soil analyses listed above. <br /> 7.3 Disposal of Drill Cuttings <br /> Drill cuttings from the well borings will be retained in 55-gal., close-topped, steel drums. <br /> When full, the drums will be closed and placed in storage on the 7500 West Eleventh Street <br /> property until the results of analyses of soil and water samples are available. When the <br /> analytical results are obtained, the soil in the drums will be classified and, if clean, disposed <br /> as clean fill on the 7500 West Eleventh Street property. Soil affected by components of fuel <br /> hydrocarbons will be loaded into a truck and shipped for disposal at the Forward Landfill, a <br /> Class II disposal facility in Manteca, California. <br /> x� <br /> sic <br /> - <br />
