e <br /> 28 April 2000 <br /> AGE-NC Project No 00-0232 <br /> Page 2 of 5 <br /> 21 PRE-FIELD WORK ACTIVITIES <br /> An updated health and safety plan will be prepared in accordance with Occupational Safety and <br /> Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational <br /> Safety and Health Administration, U S Coast Guard and U S Environmental Protection Agency, <br /> 1985) Pnor to mobilization,the area to advance three soil probe borings will be clearly marked and <br /> a utility clearance obtained through Underground Service Alert <br /> 22 SOIL SAMPLE COLLECTION AND ANALYSIS <br /> Initially, AGE proposes to advance twelve soil probe borings and six hand-auger borings to assess <br /> the lateral and vertical extent of the MTBE-impacted soil and ground water Six of the probe borings <br /> will be advanced near the existing storm drainage system The remaining six probe borings will be <br /> advanced north and southwest of the existing USTs, east and southeast of the fuel islands and <br /> between the fuel islands and USTs Six hand auger boring will be advanced directly beneath the <br /> dispensers to collect shallow soil samples Proposed bonng locations are illustrated in Figure 2 <br /> • The proposed probe bonng locations maybe modified due to field observations or additional bonngs <br /> may be advanced with approval by the CVRWQCB Each proposed bonng will be advanced to 20 <br /> feet bsg Each hand auger bonng will be advanced to 2 or 3 feet bsg <br /> Soil samples will be collected from each probe boring at five-foot intervals to total boring depths <br /> Field procedures for advancement of borings and collection of soil samples are presented in Section <br /> 3 1 and 3 2 A soil sample will be collected from each hand auger boring at total depth <br /> Soil samples from each boring will be submitted for laboratory analysis with the concurrence of the <br /> CRWQCB-CVR The selected soil samples will be analyzed by a State of California Department 0­f <br /> Health Services (DHS)-certified laboratory for the following constituents <br /> • Total petroleum hydrocarbons quantified as gasoline (TPH-g) by EPA Method 8260B, <br /> • Volatile aromatics(benzene,toluene,ethyl benzene and xylenes,BTEX)by EPA 8260B,and <br /> • Fuel oxygenates including MTBE, tertiary-butyl alcohol (TBA), di-isopropyl ether(DIPE), <br /> ethyl tertiary-butyl ether(ETBE),tertiary-amyl methyl ether(TAME),methanol and ethanol <br /> by EPA Method 8260B <br /> • <br /> Advanced GcoEnvironmcntal,Inc <br />
