r <br /> r <br /> 2.0 SCOPE OF WORK <br /> The objectives of the proposed scope of work are to investigate the extent of any impacted soil and <br /> groundwater associated with the former USTs so that remedial options-can-be.-evaluated and to' - -_ _ . . <br /> establish a groundwater monitoring capability at the site. To achieve the project objectives, a scope <br /> of work consisting of the following four tasks is proposed: <br /> 1. Project Planning I <br /> 2. Soil and Groundwater-Grab Sampling and Analysis <br /> 3. Monitoring Well Installation, Development, Sampling and Analysis <br /> 4. Environmental Site Investigation Report <br /> 2.1 Project Planning <br /> The project planning task will include permitting, notifications and an underground utility survey. A <br /> site-specific health and safety plan has been prepared in accordance with 29 CFR 1910,120 <br /> (Appendix A). The health and safety plan includes safety procedures for work to be performed, <br /> chemical hazard information, site safety officers, and a medical emergency location. ! <br /> To perform the proposed scope of work, a permit will be obtained from San Joaquin County Public <br /> Health Services Environmental Health Division (PHS/EHD). Since all of the drilling will be <br /> conducted on-site, neither off-site access agreements nor encroachment permits will be required. <br /> At least 48 hours prior to field-work, PHSIEHD will be notified so that any inspections can be <br /> scheduled. Underground Service Alert will also be notified to perform a utility clearance inspection. <br /> 2.2 Soil and Groundwater-Grab Sampling and Analysis <br /> To investigate the lateral and vertical extent of impacted soil and the lateral extent of impacted <br /> groundwater, soil and groundwater-grab samples will be collected for analysis from 6 on-site soil <br /> borings. The soil borings will be drilled by a truck-mounted drill rig, equipped with 8-inch diameter <br /> hollow stem augers. Three of the 6 sample locations will be converted into groundwater monitoring <br /> wells. <br /> Five of the 6 sample locations are positioned approximately 60 to 120 feet from the former UST <br /> excavation (Figure 2). The sixth location is positioned approximately 250 south of the former UST. <br /> 6 <br />
