PREVIOUS SITE ASSESSMENTS <br /> No additional assessment activities were performed at the site except for samples collected during <br /> the UST removal in September 1989. <br /> 3.0. SCOPE OF WORK <br /> AGE proposes to collect soil samples to determine if petroleum hydrocarbon and/or lead-impacted <br /> soil and/or ground water is present beneath the site. The limited site assessment will include the <br /> following tasks: <br /> • Permitting and pre-field work activities; <br /> • Soil sample collection and analysis; <br /> • Report preparation <br /> The preliminary site assessment tasks are discussed below. <br /> 3.1. PRE-FIELD WORK TASKS <br /> A health and safety plan will be prepared in accordance with Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety <br /> and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). <br /> Prior to mobilization,the area of excavation will be clearly marked and a utility clearance obtained <br /> through Underground Service Alert. <br /> 3.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> AGE proposes to advance two probe borings using direct push technology in the areas of the former <br /> UST and piping to assess for petroleum hydrocarbon-and/or lead-impacted soil beneath the site.The <br /> two borings will be advanced to depths of between 20 and 25 feet below surface grade (bsg); the <br /> proposed probe boring locations may be modified due to field observations. As each boring is <br /> advanced, soil samples will be collected at 5-foot intervals beginning at 5 feet bsg and extending to <br /> the total depth of the probe boring. <br /> Advanced GeoEnvironmental,Inc. <br />
