Approximately 50 to 100 cubic yards of impacted soil will <br /> be removed from during this phase of excavation. Excavation will be monitored and <br /> directed using a photo-ionization detector. Upon removal of the impacted soil, one soil <br /> sample will be collected from the west sidewall. <br /> 4.0. PROCEDURES <br /> To meet the project objectives, the following procedures will be performed: <br /> 1) Prepare a Site Health and Safety Plan in accordance %with the Occupational Safety <br /> and Health Guidance Manual for Hazardous Waste Site Activities - Prepared by <br /> National Institute for Occupational Safety and Health, Occupational Safety and <br /> Health Administration, U.S. Coast Guard and U.S. Environmental Protection <br /> Agency, October 1985. <br /> 2) Notify the San Joaquin County Environmental Public Health Services - <br /> Environmental Health Division (PHS/EHD) 48 hours prior to commencement of any <br /> work. <br /> 3) Excavate the contaminated soil using a excavator. We estimate the removal of 50 to <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" <br /> stockpiles and "impacted" stockpiles based upon PID measurements. <br /> 5) Stockpile the excavated soil adjacent to the excavation. <br /> 6) If necessary, spray the excavated soil with water to minimize the release of volatile <br /> organic compounds into the atmosphere. <br /> 7) Collect soil samples) from the west sidewall of the excavation. Initially, only one (1) <br /> soil sample will be collected. Samples will be collected from the excavator bucket <br /> and preseived in pre-cleaned brass tubes. <br /> 8) Seal samples with aluminum foil or Teflon sheets, cap, and store on ice pending <br /> transportation to a state-certified laboratory. <br /> 9) Label and log soil samples on a chain of custody form. <br />
