PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> A site assessment boring permit will be obtained from the SJCEHD for all off-site borings. A City <br /> of Stockton encroachment permit will be obtained to perform the work.A health and safety plan will <br /> be prepared in accordance with Occupational Safety and Health Guidance Manual for Hazardous <br /> Waste Site Activities (National Institute for Occupational Safety and Health Administration, U.S. <br /> Coast Guard and U.S. Environmental Protection Agency, 1985). Prior to mobilization,the area of <br /> excavation will be clearly marked and a utility clearance obtained through Underground Service <br /> Alert. <br /> 3.2. DRILLING <br /> AGE proposes to initially advance two soil probe borings at the site to collect soil and grab ground <br /> water samples for the site assessment. Proposed probe boring locations are illustrated in Figure 2. <br /> Based on soil contamination previously encountered beneath the former UST, AGE proposes soil <br /> borings on the east and west side of the UST excavation. <br /> The proposed probe boring locations may be modified due to field conditions or additional borings <br /> may be advanced to determine the lateral extent of hydrocarbon impacted soil and ground water,as <br /> directed by the SJCEHD.Each proposed probe boring will be advanced to approximately 35 feet bsg <br /> or until ground water is encountered. <br /> 3.3. SOIL AND GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> Soil samples will be collected at 5-foot intervals beginning at 5 feet bsg to the total depth of each <br /> boring.A grab groundwater sample will be collected from the boring located on the east sidei� a� V <br /> UST excavation. Field procedures for advancement of borings and collection of soil and ground <br />
