05 October 2001 AGE-NC Project No. 0 1-0871 Page 3 of 5 3.0. SCOPE OF WORK AGE proposes to collect soil samples to determine if petroleum hydrocarbon and/or MTBE-impacted soil and/or ground water is present beneath the site. The phase If site assessment will include the following tasks: • Permitting and pre-field work activities; • Soil sample collection and analysis; • Report preparation. The preliminary site assessment tasks are discussed below. 3.1. PRE-FIELD WORK TASKS A 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). Prior to mobilization,the area of excavation will be clearly marked and a utility clearance obtained through Underground Service Alert. 3.2. SOIL SAMPLE COLLECTION AND ANALYSIS AGE proposes to advance one soil probe boring using direct push technology in each of the former UST areas on the site to assess for petroleum hydrocarbon- and/or MTBE-impacted soil and/or ground water beneath the site.Proposed probe boring locations are illustrated in Figure 2. The three probe borings will be advanced to 20 feet bsg.The proposed probe boring locations maybe modified due to field observations. Soil samples will be collected at 5-foot intervals beginning at 5 feet bsg extending to the total probe boring depths. Field procedures for advancement of probe borings and collection of soil samples are presented in Sections 4.1 and 4.2. Selected soil samples from each probe boring will be submitted for laboratory analysis. The selected soil samples will be analyzed by a State of California Department of Health Services (DHS)-certified laboratory for the following constituents: • TPH-g in accordance with EPA Method 8015 and 8020; Advanced GeoEnvironmental,Inc.
