SCOPE OF WORK <br /> AGE proposes to collect soil samples to determine if petroleum hydrocarbon and/or methyl-tertiary <br /> butyl ether (MTBE)-impacted soil is present beneath the site. The preliminary site assessment will <br /> include the 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 /> 2.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> A site assessment boring permit will be obtained from the EHD for all on-site boring locations. In <br /> addition, a health and safety plan will. be prepared in accordance with Occupational Safety and <br /> Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational <br /> Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, <br /> 1985). <br /> 2.2. SOIL SAMPLE COLLECTION AND ANALYSIS <br /> AGE proposes to advance three soil borings utilizing a hand auger: one boring will be advanced <br /> beneath the distribution box(D-Box) area and one boring will be advanced beneath the end of each <br /> of the two leach lines, before emptying to the leach line pit. The borings will be advanced to <br /> determine if petroleum hydrocarbons and/or MTBE are present in the septic tank and leach line area. <br /> Each boring will be advanced to approximately 4 feet below surface grade (bsg) at an approximate <br /> 45 degree angle to extend under the above-mentioned locations. The proposed boring locations are <br /> illustrated in Figure 2; the proposed boring locations may be modified due to exact location of <br /> distribution box and leach line pit. Field procedures for advancement of borings and collection of <br /> soil samples are presented in Sections 4.1 through 4.3. <br /> The soil sample from each boring will be submitted for laboratory analysis. The selected samples <br /> will be analyzed by a State of California Department of Health Services (DHS)-certified laboratory <br /> for the following constituents: <br /> Total petroleum hydrocarbons as gasoline (TPH-g) in accordance with EPA Method 8015 <br /> Advanced GeoEnvironmental <br />
