To meet the project objectives, the following procedures will be performed: 1) Prepare a site health and safety plan in accordance with the Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities - Prepared by National Institute for Occupational Safety and Health, Occupational Safety and Health Administration, U. S. Coast Guard and U. S. Environmental Protection Agency, October 1985. 2) Notify the San Joaquin County Environmental Public Health Services - Environmental Health Division (PHS/EHD) 48 hours prior to commencement of any work. 3) Drill one boring to a depth of 20 - 25 feet using a truck- mounted, continuous-flight, 8-inch diameter hollow-stem augers. The estimated boring location .is depicted on Figure 2 . 4) Obtain soil samples at five foot intervals using a split-tube sampler loaded with three pre-cleaned brass tubes. 5) Preserve soil sample in the middle brass tube by covering both . ends with aluminum foil, capping, and sealing with tape. 6) Label and log soil samples on a chain-of-custody form. 7) Store the samples under ice and transport the samples in a chilled container to a State certified laboratory for analysis. 8) Log auger returns in accordance with the Unified Soil Classification System. 9) Monitor auger returns and soil sample duplicates for the presence of volatile organics using a photo-ionization detector (PID) pre-calibrated to isobutylene. 10) Decontaminate sampling equipment in a tri-sodium phosphate solution (TSP) and rinse twice with water prior to each sampling run. 11) Steam-clean auger flights after drilling. 12) Contain soil cuttings in 55-gallon DOT drums and store on-site pending analytical results. 13) Complete pilot borings as 2-inch groundwater monitoring wells using the well design depicted in Figure 3 . --rye 14) No sooner than 48 hours after installation, measure to the nearest 0. 01 foot, the static water level in the wells. 3
