22 August 2000 AGE-NC Project No. 00-0746 Page 2 of 5 3.0. SCOPE OF WORK AGE proposes to collect soil and discrete ground water samples to determine if petroleum hydrocarbon-impacted soil and/or ground water is present beneath the site. The preliminary phase II site assessment will consist of the following tasks: • Permitting and pre-field work activities; • Soil sample collection and analysis; • hr-situ ground water sample collection and analysis; • Report preparation. The preliminary site assessment tasks are discussed below. 3.1. PRE-FIELD WORK ACTIVITIES 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 an utility clearance obtained through Underground Service Alert. 3.2. SOIL SAMPLE COLLECTION AND ANALYSIS Initially, AGE proposes to advance three soil probe borings using direct push technology(DPT) in the vicinity of the former UST area to determine if petroleum hydrocarbon-impacted soil and/or ground water is present beneath the site. Proposed probe boring locations are illustrated in Figure 2. The proposed probe boring locations may be modified due to field observations or additional borings may be advanced with approval by the PHS-EHD. Each proposed probe borings will be advanced to 25 feet bsg or until the field observations and field screening using an organic vapor monitor (OVM) indicate that detectable petroleum vapors are not present in the soil samples screened from two consecutive five-foot intervals. Soil samples will be collected at 5-foot intervals beginning at 5 feet bsg extending to the total probe boring depths. Advanced GeoEnvironmental,Inc.
