SCOPE OF WORK <br /> AGE proposes to collect soil samples to determine if petroleum hydrocarbon-impacted soil and/or <br /> ground water is present beneath the site. The limited subsurface investigation will include the <br /> following tasks: <br /> • Permitting and pre-field work activities; <br /> • Soil and ground water 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 AND GROUND WATER SAMPLE COLLECTION AND ANALYSIS <br /> a <br /> AGE proposes to advance soil borings at the site.Each boring shall be advanced to a maximum <br /> depth of 25 feet below surface grade(bsg); ground water is anticipated to occur between 15 and 25 <br /> feet bsg. Soil samples may be collected at five-foot intervals; a grab ground water sample will be <br /> collected from each boring; the proposed probe boring locations may be modified due to field <br /> observations. <br /> The proposed probe boring locations are illustrated on Figure 2. Field procedures for advancement <br /> of probe borings and collection of soil and ground water samples are presented in Sections 4.1 and <br /> 4.2. <br /> Selected soil and ground water samples from each probe boring will be submitted for laboratory <br /> analysis. The selected samples will be analyzed by a State of California Department of Health <br /> Services (DHS)-certified laboratory for one or more the following constituents: <br /> Advanced GeoEnvironmental,Inc. <br />
