PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> A site assessment boring permit will be obtained from the SJCEHD for all on-site borings locations <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 AND GROUNDWATER SAMPLE COLLECTION AND ANALYSIS <br /> Initially, a single soil boring will be advanced near the former dispenser area; the proposed soil <br /> boring location is presented in Figure 2. If hydrocarbon-impacted soil and/or ground water is <br /> encountered in samples from the initial boring,additional soil borings maybe advanced as necessary <br /> to determine the lateral and vertical extent of contamination. <br /> The soil boring will be advanced to a depth of approximately 45 feet bsg or until ground water is <br /> encountered. Soil samples will be collected from the boring at a minimum of five-foot intervals. <br /> Procedures for advancement of soil borings and soil sampling are presented in Section 4.1. <br /> Up to six soil samples from the initial boring will be selected for laboratory analysis. Soil samples <br /> for laboratory analysis will be selected based on visual observations of petroleum hydrocarbon <br /> impact, organic vapor meter(OVM) readings, changes in lithology, and/or at the capillary fringe. <br /> Select soil samples will be analyzed by a State of California Department of Health Services(DHS)- <br /> certified laboratory for the following constituents: <br /> Advanced GeoEnviron mental,Inc. <br />
