Soil <br /> impacted by petroleum hydrocarbons was encountered in June 1999 and September 1999 <br /> during grading and excavation activities conducted during site redevelopment. The following <br /> paragraphs discuss the excavation, characterization and verification, transportation, and <br /> disposal of the soil. <br /> Soil Excavation Activities -June 1999 <br /> An area of soil impacted by petroleum hydrocarbons was encountered by Giardino Construction <br /> north of the former Discovery Chevrolet Service Bay building during grading activities at the <br /> subject property in June 1999. On June 29, 1999, ENSR observed the excavation of 128 tons <br /> of petroleum hydrocarbon impacted soil in this area. The soil was excavated by Giardino <br /> Construction using a backhoe. impacted soil was removed from an area measuring <br /> approximately 20 feet by 18 feet to a depth of approximately 11 feet. The petroleum <br /> hydrocarbon impacted soil was stockpiled on plastic sheeting and covered with plastic. The <br /> location of the excavation is presented in Figure 1 (Attachment 1). <br /> ENSR collected six verification soil samples from the excavation and one composite soil sample <br /> from the stockpiled soil. Two verification soil samples were collected from the bottom of the <br /> excavation (samples FS and FN) and one verification soil sample was collected from each of <br /> the excavation sidewalls (samples WW, WE, WN, and WS). The soil samples were delivered to <br /> McCampbell Analytical Inc. of Pacheco, California, a State-certified hazardous waste testing <br /> laboratory. The soil samples were analyzed for volatile halocarbons, benzene, toluene, <br /> ethylbenzene, xylenes (BTEX), methyl tent-butyl ether (MTBE) and the full carbon range of total <br /> petroleum hydrocarbons (TPH) by EPA Methods 8010, 8020 and 8015 modified, respectively. <br /> Yerificationt <br /> Volatile halocarbons, benzene, and MTBE were not detected above the laboratory detection <br /> limits in the verification soil samples collected from the excavation bottom or sidewalls.
