PRE-FIELD WORK ACTIVITIES <br /> A health and safety plan will be prepared in accordance with Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety <br /> and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). <br /> Prior to mobilization, the area of excavation will be clearly marked and a utility clearance obtained <br /> through Underground Service Alert. <br /> 3.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> Initially, AGE proposes to advance one soil probe boring using direct push technology. The soil <br /> boring will be advanced within the former UST excavation area to evaluate the vertical extent of the <br /> petroleum hydrocarbon impact on soil and ground water. If significant hydrocarbon-impacted soil <br /> is encountered, additional probe borings will be advanced to adequately detennine the lateral extent <br /> of hydrocarbon-impacted soil. The initial proposed probe boring location is illustrated in Figure 2. <br /> Boring locations marry be modified due to field observations or additional borings may be advanced <br /> with approval by the PHS-EHD. Each proposed boring will be advanced to 20 feet bsg or until the <br /> field observations and field screening using an organic vapor meter (OVM) indicate that detectable <br /> petroleum hydrocarbons vapor is not present in the soil samples screened from two consecutive five- <br /> foot intervals. <br /> Soil samples will be collected at 5-foot intervals beginning at 5 feet bsg extending to the total boring <br /> depths. Field procedures for advancement of borings and collection of soil samples are presented in <br /> Section 4.1.1. <br /> Selected soil samples will be submitted for laboratory analysis by a State of California Department <br /> of Health Services (DHS)-ce14ified laboratory. Samples will be analyzed for the following <br /> constituents: <br /> Advanced GeoEnvironmental,Inc. <br />
