2 <br /> the present dimensions. <br /> Excavated soil will be screened by GeoAudit using a photo-ionization detector (PID). <br /> Based upon organic vapors detected by the PID, the excavated soil will be segregated into <br /> "clean" and impacted stockpiles. The excavated soil will be stockpiled on plastic sheeting <br /> near the southern portion of the property. <br /> 4.0 PROCEDURES <br /> In order to meet the project objectives, the following activities will be performed: <br /> 1) Prepare a site health and safety plan in accordance with Occupational Safety and <br /> Health Guidance Manual for Hazardous Waste Site Activities (Prepared by National <br /> Institute for Occupational Safety and Health Administration, U.S. Coast Guard and <br /> U.S. Environmental Protection Agency, 1985). <br /> 2) Notify PHS/EHD 48 hours prior to field work. <br /> 3) Excavate the impacted using an excavator. We anticipate removing approximately <br /> 50 to 100 cubic yards of impacted soil from the former UST area. An additional one <br /> to two cubic yards will be removed from the dispenser area (see Figure 2). <br /> 4) As excavation proceeds, monitor excavated soil for the presence of volatile organics <br /> using a photo-ionization detector (PID). Soil will be segregated into "clean" <br /> stockpiles and "contaminated" stockpiles based upon PID measurements. <br /> 5) Stockpile the excavated soil on plastic sheeting, pending analytical results. <br /> Contaminated soil will be stockpiled on the southern portion of the property; "clean" <br /> soil will be stockpiled immediately east of the excavation. The clean soil will be used <br /> to backfill the excavation upon completion of digging (Figure 2). <br /> 6) If necessary, spray the excavated soil with water to minimize the release of volatile <br /> organic compounds into the atmosphere. Upon completion of excavation activities, <br /> the removed soil will be covered with plastic sheeting. <br /> 7) Collect soil samples from the sidewalls and floor of excavation with the excavator <br /> bucket in pre-cleaned brass tubes as directed by a representative of the San Joaquin <br /> County Public Health Services - Environmental Health Division (PHS/EHD). We <br /> estimate the collection of a total of seven soil samples. <br /> 8) Seal samples with aluminum foil, cap, and store on ice pending transportation to a <br /> state-certified laboratory. <br /> G_68io1 Audra Services,Ine. <br /> SG95-01-1076-OWDUNfRY MART/- <br /> 2 <br />
