0 <br /> CAMBRIA <br /> encountered on the western side of the UST excavation Approximately 34 7 tons of soil was <br /> segregated and placed on and covered with plastic sheeting During trenching activities, one <br /> steel pipe, presumably an abandoned product line, was found Cambna coordinated disposal of <br /> the soil stockpile and the pipe,on behalf of Shell,as discussed below <br /> UST Soil Sampling: Cambria collected two soil samples (DT-1 and DT-2) from the bottom of <br /> the UST excavation at a depth of approximately 12 5 feet below grade Sampling locations are <br /> shown on Figure 2 Soil samples were collected from the tank excavation bottom using a <br /> backhoe The soil was removed from the backhoe bucket, packed into clean brass sample tubes, <br /> and the tube ends were covered with Teflon tape and plastic end caps Soil samples were <br /> labeled,placed into a cooler with ice,entered onto a chain of custody record, and transported to a <br /> California-certified analytical laboratory for chemical analyses <br /> i <br /> Chemical Analyses: The soil samples were analyzed for total petroleum hydrocarbons as <br /> gasoline (TPHg),benzene, toluene, ethylbenzene, xylenes (BTEX), and fuel oxygenates (MTBE, <br /> DIPS, ETBE, TAME, TBA, and ethanol) by EPA Method 8260B and total petroleum <br /> hydrocarbons as diesel(TPHd)by EPA Method 8015 (Modified) <br /> UST Installation: One 12,000-gallon fiberglass diesel UST was installed on March 29, 2002 A <br /> representative from Cambria was not present during the installation of the tank <br /> ANALYTICAL RESULTS <br /> No TPHd, TPHg, BTEX, or fuel oxygenates were detected in either of the samples collected <br /> from the UST excavation <br /> Soil analytical results are summarized in Table 1 and TPHd, TPHg,benzene, and MTBE data are <br /> presented on Figure 2 The certified analytical report is included in Appendix A <br /> DISPOSAL ACTIVITIES <br /> Soil Disposal. The soil stockpile was sampled and profiled for disposal (Appendix A) On April <br /> 12, 2002, Manley and Sons Trucking, Inc of Sacramento, California transported the soil to <br /> Allied Waste's Forward Landfill to Manteca, California for disposal Confirmation of the soil <br /> disposal is included as Appendix B <br /> Pipe Disposal: On June 17, 2002, Ecology Control Industries transported the pipe to their <br /> . facility in Richmond,California for disposal The manifest is included as Appendix C <br /> 0955 2 <br />
