approximately two feet to the south and west (to the property lines) and deepened <br /> by approximately 8 feet. The volume of soil that will be removed is approximately <br /> 100 cubic yards. <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"stockpiles <br /> 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 adjacent to the excavation. The clean soil will <br /> be used to backfill the excavation upon confirmation of the successful removal of <br /> contamination. <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). <br /> 8) Seal samples with aluminum foil, cap, and store on ice pending transportation to a <br /> state-certified laboratory. <br /> 9) Label and log soil samples on a chain-of-custody form. <br /> 10) Analyze soil samples for total petroleum hydrocarbons (TPH as gasoline and diesel) <br /> and volatile aromatics (BTE&X) in accordance with EPA methods 8015m and 8020, <br /> respectively. <br /> The opportunity to prepare this work plan is greatly appreciated.
