r- s • • <br /> C A M B R I A <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. Cambria 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 /> 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 /> DIPE, 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 in 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 />
