The Phase I report recommended soil sampling beneath the former USTs, steam bay separator, solvent recycling areas and hydraulic lift sites. 3.0. SCOPE OF WORK AGE proposes to collect soil samples to determine ifpetroleum hydrocarbon and/or MTBE-impacted soil and/or ground water is present beneath the site. The phase H 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 six probe borings using direct push technology in the areas of the four former USTs, existing steam-bay separator(clarifier) and existing solvent recovery area on the site to assess forpetroleum hydrocarbon-and/or MTBE-impacted soil beneath the site.All of the borings will be advanced to depths of 20 feet below surface grade(bsg);the proposed probe boring locations may be modified due to field observations. As each boring is advanced, soil samples will be collected at 5-foot intervals beginning at 5 feet bsg and extending to the total depth of the probe boring. Advanced GeoEnvironmental,Inc.
