13 April 1993 <br /> (GeoAudit-1. 33) <br /> Page 3 of 5 <br /> To meet the project objectives, the following activities will be <br />' performed: <br /> 1) Prepare a site health and safety plan (SHSP) in accordance <br /> with the Occupational Safety and Health Guidance Manual for <br /> I Hazardous Waste Site Activities (National Institute for <br /> Occupational Safety and Health, Occupational Safety and Health <br /> Administration, U. S. Coast Guard and U. S. Environmental <br /> IProtection Agency, October 1985 attached) . <br /> 2) Obtain permits required by the San Joaquin County Public <br /> Health Services '- Environmental Health Division (PHS/EHD) <br /> and/or the City of Lodi. <br /> 3) Notify the CVRWQCB and PHS/EHD 72 hours prior to initiating <br /> Iany work, <br /> 4) Prior to initiation of work, brief all involved personnel with <br /> the contents of the SHSP. <br /> 5 Using a truck-mounted drilling rig with hollow stem augers, <br /> drill approximately (6) soil borings in the area of the former <br /> UST' s and dispenser island. The approximate locations are <br /> illustrated on Figure 2. <br /> I 6) Obtain discrete soil samples at five-foot intervals or changes <br /> in lithology using a split-spoon sampler loaded with three <br /> pre-cleaned brass tubes. Decontaminate sampling equipment <br />' using a cleansing solution and rinse twice with water prior to <br /> collection of each sample. <br /> 7) Preserve asoil sample from each interval by covering both <br /> ends of the sample tube with aluminum sheets, capping and <br /> sealing with tape. Label and log soil samples on chain of <br /> custody form. <br />' 8) Transport samples in a chilled container under chain of <br /> custody and relinquish the samples to a state certified <br /> laboratory for analysis within 24 hours. A state certified <br />' mobile laboratory may be used for analysis on-site. <br /> 9) Analyze selected soil samples for total petroleum hydrocarbons <br />' (TPH as gasoline) and for purgeable aromatics in accordance <br /> with the DHS approved method for gasoline and EPA method 8020, <br /> respectively. <br /> 10) Monitor auger returns and soil sample duplicates for the <br /> presence of organic vapors using a photo-ionization detector <br /> (PID) . <br /> 1 <br />
