I <br /> During tank removal activities and excavation for the new tank cavity, approximately 900 <br /> . cubic yards of soil was generated The soil was transported to Forward Incorporated, <br /> Stockton, California for disposal The certificate of disposal and uniform hazardous waste <br />' manifest for each tank, as well as the manifests for soil disposal, are presented in <br /> Appendix A <br />' 3 2 Soil Sampling <br /> After tank removal, a soil sample (Tank-E-9') was collected from the used oil tank cavity at <br />' 9 feet below grade On July 25, 1995, at the direction of SJCPHS, nine soil samples (Tank <br /> Pit-1 through Tank Pit-9) were collected after removal of the four product tanks (Tanks A <br /> through D) and over-excavation of the tank cavity to 15 feet below grade The cavity was <br />' over-excavated to accommodate the new tanks <br /> On July 21 and 25, 1995, seven soil samples (PLA through PL-7) were collected at depths of <br />' 2 to 4 feet from the dispenser island and product line cavities The results of the soil sample <br /> analysis are presented in Table 1 and the soil sample locations are shown on Figure 2 <br />' 4 0 ANALYTICAL METHODS <br />' The soil samples were analyzed by Argon Labs, Ceres, California, a state-certified laboratory, <br /> using standard test methods of the United States Environmental Protection Agency (EPA) <br /> and the Cahfonua Department of Health Services The soil samples were analyzed for the <br /> following constituents <br /> • Total petroleum hydrocarbons as gasoline (TPH-G) using EPA Methods 5030/8015 <br />' (modified) <br /> • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) using EPA <br /> Methods 5030/8020 <br />' • Total lead using EPA Methods 3050/7420 <br />' Additionally, Soil Sample Tank-E-9', collected from the used oil tank cavity was analyzed for <br /> the following <br />' • Total petroleum hydrocarbons as diesel (TPH-D) using EPA <br /> Methods 3550/8015 (modified) <br />' • Total oil and grease (TOG) using EPA Methods 3550/5520 <br /> • Polychlorinated biphenyls (PCBs) using EPA Methods 3550/8080 <br />' • Cam 5 metals (cadmium, chromium, lead, zinc, and nickel) using EPA <br /> Methods 3050/6010 <br />' • Halogenated volatile organic compounds (HVOCs) using EPA Method 8010 <br /> E\0\10-280\TANK RM112295 3 <br />
