SCOPE OF WORK <br /> Based upon the historical use of the property,the uncertainty regarding the sampling the former UST <br /> area and other areas of concern noted during a site reconnaissance, AGE proposes to collect soil <br /> samples to determine ifpetroleum hydrocarbon-impacted soil and/or groundwater is present beneath <br /> the site. The limited site assessment will include the following tasks: <br /> • Permitting and pre-field work activities; <br /> • Soil sample collection and analysis; <br /> • Grab ground water collection and analysis; and <br /> • Report preparation <br /> Each task is discussed below in greater detail. <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 three probe borings using direct push technology. One boring will be <br /> advanced within the former UST excavation area to a depth of approximately 20 to 25 feet bsg;two <br /> additional soil borings will be advanced to depths of 5 feet bsg near a waste oil confinement area and <br /> an area of noted surface (waste oil) discoloration. The proposed probe boring locations may be <br /> modified due to field observations. Soil samples will be collected in the deeper boring at five-foot <br /> intervals; soil samples will be collected at depths of 2 feet and 5 feet in the shallow borings. <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 /> Selected soil samples from each probe boring will be submitted for laboratory analysis.The selected <br /> soil samples will be analyzed bya State of California Department of Health Services(DHS)-certified <br /> Advanced GmEnvironmental,Inc. <br />
