24 July 2002 <br /> AGE-NC Project No. 02-0948 <br /> Page 3 of 5 <br /> potential environmental concerns at the site.The Phase I report recommended soil sampling beneath <br /> the former USTs, former dispenser area, hydraulic lifts, clarifier and former paint booth locations <br /> and inspecting the integrity of the concrete flooring in the battery- and lubricant-storage areas. <br /> 3.0. SCOPE OF WORK <br /> AGE proposes to collect soil samples to determine ifpetroleum hydrocarbon and/or MTBE-impacted <br /> soil and/or ground water is present beneath the site. The phase II 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-FIELDWORK 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 up to eleven soil probe borings using direct push technology in the areas <br /> of the existing hydraulic lifts, former USTs, former dispenser, existing clarifier, former battery <br /> storage area and former paint booth area on the site to assess for petroleum hydrocarbon- and/or <br /> MTBE-impacted soil beneath the site. Eight of the borings will be advanced to depths of 20 feet <br /> below surface grade(bsg)and three borings will be advanced to depths of 10 feet bsg;the proposed <br /> probe boring locations may be modified due to field observations. As each boring is advanced, soil <br /> samples will be collected at 5-foot intervals beginning at 5 feet bsg and extending to the total probe <br /> boring depths. <br /> The proposed probe boring locations are illustrated in Figure 2. Field procedures for advancement <br /> of probe borings and collection of soil samples are presented in Sections 4.1 and 4.2. <br /> Advanced GeoEnvironmental,Inc. <br />
