PERMITTING AND PRE-FIELD WORK PREPARATIONS Applicable soil boring permits will be obtained from SJCEHD. An update to the health and safety plan presently on-file will be prepared in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). Prior to mobilization, the area of excavation will be clearly marked and a utility clearance obtained through Underground Service Alert. The SJCEHD will be contacted at least 48 hours prior to conducting any field work. 3.2. SOIL PROBE BORING AND SAMPLING AGE proposes to advance up to ten (10) soil probe borings utilizing a direct push drilling rig to evaluate the presence and define the type or extent of petroleum hydrocarbon- impacted soil between 5 and 20 feet bsg. Proposed soil boring locations are depicted in Figure 2. A description of proposed soil boring locations is provided below: • Three soil borings will be advanced in the area of the former service station located in the southern portion of the site on parcel 171-300-13; • One soil boring will be advanced in the area between the Interior Steam Cleaner and the Truck wash building, in the area of the septic system and drainage line on parcel 171-300-18; and • Six soil borings will be advanced in the area of the former service station located in the northern portion of the site on parcel 171-300-03; 3.3.
