17 August 2012 AGE-NC Project No. 01-0887 Page 3 of 6 PERMITTING AND PRE-FIELD WORK PREPARATIONS A site specific health and safety plan 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). All field personnel will be trained in hazardous materials communication and will have completed a 40-hour Health and Safety Course as specified in OSHA Hazardous Waste Operations and Emergency Response Standard [29 CFR 1910.120(e)], and 8-hour annual refresher courses as necessary. Additional information regarding site information will be provided to parties upon request where and when available. Prior to mobilization, each soil boring location will be clearly marked and a utility clearance obtained through Underground Service Alert. All necessary permits will be procured and present on-site during drilling activities. PROBING AND COLLECTION OF SOIL VAPOR SAMPLES AGE proposes to advance three soil-vapor probe borings to evaluate the potential threat for intrusion of petroleum hydrocarbon-impacted soil-vapor to indoor air. Shallow soil samples collected during the UST removal at depths less than five feet bsg (line and dispenser samples) justify shallow soil vapor evaluation. Due to shallow ground water levels at the site (four feet), each soil boring will be advanced to a depth of three feet below surface grade(bsg)for collection of a soil-vapor sample. Field procedures for advancement of borings and collection of soil-vapor samples are presented below. Probe borings for soil vapor will established directly north and west of warehouse building to evaluate the former product line release and dissolved petroleum plume; while another boring will be established northeast of the second building on-site. Proposed boring locations are presented in Figure 2. Soil-vapor samples will be analyzed by a State of California Department of Public Health Services (CDPH)-certified laboratory for the following constituents: • Total petroleum hydrocarbons quantified as gasoline (TPH-g) in accordance with EPA Method TO-3; I r p • BTEX and volatile organic compounds(VOCs)including all oxygenated compounds in accordance with EPA Method TO-15; and A • Isopropyl alcohol (tracer gas) in accordance with EPA Method 8015M/TO-15. - Advanced GeoEnvironmental,Inc.
