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 3oaquin County Environmental Public Health Services - <br /> Environmental Health Division (PHS/EH D) 48 flours prior to commencement of any <br /> work. <br /> 3) FXCilVate the contaminated soil using a backhoe. The approximate area to be <br /> excavated will be 15 feet by 20 feet. Assuming the removal of impacted soil to a <br /> depth of approximately 8 feet, the volume of soil thilt will be removed will be <br /> approximately 100 cubic yards. The proposed excavation limit` are illustrated in <br /> Figure 2. <br /> 4) As excavation proceeds, monitor excavaled sail for the presence of volatile organics <br /> using a photo-i(mizatlon detector (PID). Soil will be segre`ated into "clean" <br /> stockpiles and "Impacted" stockpiles based upon PID measurements. <br /> 5) Stockpile the excavated soil on plastic sheeting, pending analytical results. Impacted <br /> soil will be stockpiled near the southeast corner of the site. -1-he clean soil will be <br /> used to backfill the excavation upon completion of digging. <br /> 6) if necessary, spray the excavated soil with -,N'jitCr to I111I111111ZC the ICIcase of volatile <br /> organic coillpounds into the atmosphere. Upon colllpletion of excavation activities, <br /> the removed soil will be covered with plastic sheeting. <br /> 7) Collect soil samples from the sidewv ,Jis of the excav,Ition. Approximately four (4) soil <br /> samples will be collected. Samples will be collected from the backhoe bucket and <br /> preserved in pre-cleaned brass tubes. <br /> 8) Seal samples with aluminum foil or Tetlon 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 /> 10) Analyze soil samples for total petroleum hydrocarbons (TPH as gasoline) and volatile <br /> aromatics (BTE&X) in accordance with EPA methods S015m and 8020, respectively. <br /> AdaruM Gwl-.nvri.i ,1.1..• <br /> j-d..Sie.l h.l.le Fa.aiwn u'Y+v5 <br /> 3 <br />
