SCOPE Ok'WORK <br /> The scope of work for this site assessment includes: <br /> • Pre-field permitting; <br /> • Preparation of a health and safety plan; <br /> • Advancement of eight soil borings at various locations on the site indeatified as potential <br /> sources for subsurface contanvnation. Soil borings will be u ed for collection of soil <br /> and/or `grab' ground water samples. <br /> • Laboratory analysis of the ground water samples and selected so' samples; <br /> • Preparation of a report of findings; and <br /> • Preparation of a Health Risk Assessment based on the findings f the proposed scope of <br /> work. <br /> 4.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Prior to conducting field activities, applicable site assessment permits ill be obtained from the <br /> EHD. In addition,an updated,site-specific health and safety plan will be pr-.pared in accordance with <br /> Occupational Safety and Health Guidance Manual for Hazardous Wast Site Activities (National. <br /> Institute for Occupational Safety and Health Administration, U.S. Coast Guard and U.S. <br /> Environmental Protection Agency, 1985). Prior to mobilization, the pror osed excavation area and <br /> soil boring location will be clearly marked and an underground utility clearance will be obtained <br /> through Underground Service Alert. <br /> 4.2. SOIL BORINGS <br /> AGE proposes to advanced eight probe borings for collection of soil d/or `grab' ground water <br /> samples at various locations identified at possible sources for subs ce contamination. Probe <br /> boring willbe advanced utilizing a hollow-stem auger drill rig and"direct-�ush"techniques. Borings <br /> will be advanced as followings: <br /> • One soil boring north of the north storm water basin and north pit for collection of a <br /> `grab' ground water sample to delineate the extent of metals-imp ed ground water in the <br /> area; <br /> • Two soil borings north of the Millwork Building for collection ¢f soil and `grab' ground <br /> water samples to delineate the extent of TPH-impacted ground ater; <br /> Advanced Geo&nvironmant&4 Hu- <br />
