T �+ <br /> CAM RIA <br /> All of the tank pit soil samples were collected at a depth of approximately 17 feet below grade <br /> (fbg) The soil samples were collected from the tank pit using an excavator The soil was <br /> removed from the excavator bucket, packed into clean brass sample tubes, and the tube ends <br /> were covered with Teflon sheets and plastic end caps The sampling locations are shown on <br /> Figure 2 <br /> Dispenser and Product Piping Soil Sampling- Cambria collected soil samples (D-1 through <br /> D-4) beneath the product dispensers, soil samples (P-1 through P-9) beneath the Product piping, <br /> and soil sample P-10 beneath the UST system vent riser All soil samples were collected from <br /> native soil at an approximate depth of 4 5 to 6 fbg (Figure 2) Soil samples were collected in the <br /> same manner described above using a backhoe <br /> Waste Oil Tank Removal• One 550-gallon waste oil tank was removed on April 21, 2005 by <br /> Paradiso Mr John Jackson and Cambria field staff were present to witness the removal and <br /> condition of the tank The tank was in good condition, with no signs of failure <br /> Waste Oil Tank Soil Sampling: With guidance from Mr Jackson, Cambria staff collected a soil <br /> sample (TP-7) from beneath the waste oil tank at 9 fbg The soil sample was collected from the <br /> waste oil tank excavation in the same manner described above using a backhoe <br /> Soil Chemical Analyses. All soil samples were labeled, placed into a cooler with ice, entered <br /> onto a chain of custody record, and transported to a California-certified analytical laboratory <br /> Soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg), benzene, <br /> toluene, ethylbenzene, xylenes (BTEX), fuel oxygenates (methyl tertiary butyl ether [MTBE], <br /> di-isopropyl ether, ethyl tertiary butyl ether, tertiary butyl alcohol, and tertiary amyl methyl <br /> ether) by EPA Method 8260B Additionally,the waste oil tank pit soil sample was also analyzed <br /> for total petroleum hydrocarbons as diesel (TPHd) by EPA Method 8015M, chlorinated <br /> hydrocarbons by EPA Method 8260B, CAM 17 metals by EPA Method 6010B and 7471A, and <br /> polychlorinated biphenyls(PCBs)by EPA Method 8082 <br /> Soil Disposal. Soil generated during the UST system removal activities was stockpiled onsite <br /> and covered with plastic sheeting Stockpiled soil was sampled and profiled for disposal On <br /> May 6, 2005, Manley and Sons Trucking, Inc of Sacramento, California transported a total of <br /> approximately 103 tons of soil and pea gravel to Allied Waste Industries' Forward Landfill in <br /> Manteca, California for disposal The disposal laboratory analytical report and the disposal <br /> confirmation document are presented in Appendix A <br /> i <br /> 0797 2 <br />
