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 additional site assessment will include the <br /> following tasks <br /> • Permitting and pre-field work activities, <br /> • SoiI 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 /> Advanced GeoEnvironmental,Inc <br />
