12 August 2002 <br /> AGE-NC Pro3ect No. 99-0645 <br /> Page 5 of 8 <br /> of MTBE and hydrocarbons in soil at the site. The soil sample analytical results, SVE pilot test <br /> results, conclusions and applicable recommendations, will be included in the site assessment and <br /> feasibility report. The report will be in a format acceptable to the EHD and the CVRWQCB, and will <br /> be reviewed and signed by a California Registered Geologist. <br /> 4.0. PROCEDURES <br /> Procedures for soil boring and SVE well installation, SVE feasability testing, sampling, monitoring, <br /> are outlined below. All field procedures will be overseen by an AGE representative under the <br /> supervision of a California Registered Geologist. <br /> 4.1. PRE-FIELD WORK ACTIVITIES <br /> The following procedures will be performed prior to any digging/drilling activities: <br /> • Prepare a Site Health and Safety Plan in accordance with the Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities - Prepared by National Institute for <br /> Occupational Safety and Health, Occupational Safety and Health Administration, U.S Coast <br /> Guard and U S. Environmental Protection Agency, October 1985. <br /> • Notify the PHS-EHD a minimum of 48 hours prior to commencement of any work, while <br /> securing proper city/county soil boring or well permits. <br /> • All drilling locations will be marked at least 48 hours in advance for an Underground Service <br /> Alen (USA) check of underground utilities or pipes. <br /> 4.2. SOIL SAMPLING AND ANALYSIS PROCEDURES <br /> The soil borings will be advanced using hollow-stem auger drilling techniques. Relatively undisturbed <br /> soil samples will be collected in each boring using a California modified split-spoon sampler fitted <br /> with 2-inch diameter, 6-inch long brass sleeves. Upon removal from the sampler, the sample sleeves <br /> will be separated with a clean knife. The exposed ends of the second sleeve will be covered with <br /> Teflon sheets, capped and sealed with tape. Each soil sample will be labeled with boring location, <br /> depth. time, date and sampler's initials following sample collection. Soil samples will be placed in a <br /> chilled container under ice and transported under chain-of-custody procedure to a DHS-certified <br /> laboratory. <br /> Advanced tcoEnvironmental,Inc. <br />
