PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained from the SJCEHD , and <br /> encroachment permits will be obtained from the City of Stockton Public Works <br /> Department. In addition , an update to the health and safety plan presently on-file will be <br /> prepared in accordance with Occupational Safety and Health Guidance Manual for <br /> Hazardous Waste Site Activities (National Institute for Occupational Safety and Health <br /> Administration , U . S . Coast Guard and U . S . Environmental Protection Agency , 1985) . <br /> Prior to mobilization , each proposed boring/well locations will be clearly marked and a <br /> utility clearance obtained through Underground Service Alert, <br /> 2 .2 . DRILLING AND SAMPLE ANALYSIS <br /> r , <br /> AGE proposes to advance four off-site soil borings to depths of approximately 90 feet <br /> bsg for the purpose of logging lithology and for collection of deep grab groundwater <br /> samples . Thereafter, adjacent pilot soil borings will be advanced to depths of 40 feet <br /> bsg for the installation of off-site shallow groundwater monitoring wells . Soil borings will <br /> be advanced using a truck-mounted drill rig equipped with 8 . 25-inch hollow-stem <br /> augers . The total depth of each well boring may vary according to <br /> geologic/hydrogeologic conditions encountered during drilling . Relative to the property <br /> boundary line , locations of the off-site groundwater monitoring wells are as follows : <br /> • One soil boring and one monitoring well will be advanced approximately 175 feet <br /> west of the site in the City right-of-way (West 8th Street) to evaluate the west- <br /> southwest extent of the hydrocarbon plume ; <br /> • One soil boring and one monitoring well will be advanced approximately 150 feet <br /> south of the site in the McKinley Park asphalt parking lot to evaluate the south- <br /> southwest extent of the hydrocarbon plume ; <br /> • One soil boring and one monitoring well will be advanced approximately 220 feet <br /> southeast of the site at McKinley Park to evaluate the southeast-east extent of <br /> the hydrocarbon plume ; and <br /> • One soil boring and one monitoring well will be advanced approximately 450 feet <br /> northeast of the site in the City right-of-way (San Joaquin Street) to evaluate the <br /> east-northeast extent of the hydrocarbon plume . <br /> Advanced GeoEnvironmental Inc. <br />
