To meet project objectives, the following activities will be <br /> performed: <br /> 1) Prepare a site health and safety plan in accordance with the <br /> Occupational Safety and Health Guidance Manual for Hazardous <br /> Waste Site Activities - Prepared by National Institute for <br /> Occupational Safety and Health, Occupational Safety and Health <br /> Administration, U.S. Coast Guard and U. S. Environmental <br /> Protection Agency, October 1985. <br /> 2) Notify the PHS/EHD 48 hours prior to commencement of any work. <br /> 3) Drill three borings to depths of 30 feet. These borings may be <br /> angled 300 from vertical. Two vertical borings will be drilled <br /> to depths of 15 feet using a truck-mounted, continuous-flight, <br /> 8-inch diameter hollow-stem augers. The estimated boring <br /> locations are illustrated in Figures 2 and 3 . <br /> 4) Obtain discrete soil samples at five foot intervals using a <br /> split-tube sampler loaded with three pre-cleaned brass tubes. <br /> 5) Preserve soil sample in the middle brass tube by covering both <br /> ends with aluminum foil, capping, and sealing with tape. <br /> 6) Label and log soil samples on a chain of custody form. <br /> 7) Store the samples under ice and transport the samples in a <br /> chilled container to a State certified laboratory for <br /> analysis. <br /> 8) Log auger returns and soil samples in accordance with the <br /> Unified Soil Classification System. <br /> 9) Monitor auger returns and soil sample duplicates for the <br /> presence of volatile organics using a photo-ionization <br /> detector (PID) pre-calibrated to isobutylene. <br /> 10) Decontaminate sampling equipment in a tri-sodium phosphate <br /> solution (TSP) and rinse twice with water prior to each <br /> sampling run. <br /> 11) Steam-clean auger flights after drilling. <br /> 12) Place auger returns on plastic sheeting and store on-site <br /> pending analytical results. <br /> 13) Backfill the borings using concrete-bentonite slurry in the <br /> entire depth of the borings. <br /> 14) Analyze selected soil samples (approximately 8 - 10) for total <br /> petroleum hydrocarbons (TPH as gasoline) and BTE&X in <br /> accordance with EPA methods 8015m and 8020, respectively. <br /> 2 <br />
