2.0 SCOPE OF WORK The objectives of the proposed scope of work are to further investigate the extent of impacted soil and groundwater, establish a groundwater monitoring capability at the site, and survey possible sensitive receptors in the site vicinity. To achieve these objectives, three on-site groundwater monitoring wells will be installed and monitored and sampled on a quarterly basis for at least one year, and a survey of possible sensitive receptors within 2,000 feet of the site will be conducted. One of the proposed monitoring well soil borings will be continuously cored to delineate the subsurface soil sequence and to evaluate the vertical extent of impacted soil. 2.1 Planning and Permitting Prior to initiating fieldwork, a site-specific health and safety plan addendum will be prepared according to 29 CFR 1910.120. The health and safety plan addendum will include safety procedures for work to be performed, chemical hazard information, site safety officers, and a medical emergency location. To perform the proposed scope of work, monitoring well permits will be obtained from PHS/EHD. Since all of the drilling will be conducted on-site, neither off-site access agreements nor encroachment permits will be required. At least two working days prior to field work, Ramage Environmental will notify PHS/EHD so that any inspections can be scheduled. Underground Service Alert will also be notified to perform a utility clearance inspection. 2.2 Groundwater Monitoring Well Installations To evaluate the lateral extent of impacted groundwater and to establish a groundwater monitoring capability at the site, three on-site groundwater monitoring wells will be installed, and sampled on a quarterly basis for at least one year. One of the proposed wells will be located at r— the south end of the former UST in the vicinity of the previous Geoprobe soil boring B-2. The boring for this monitoring well will be continuously cored to delineate the subsurface soil sequence and to evaluate the vertical extent of impacted soil. Given that the regional groundwater flow direction is expected to be toward the north, the other two proposed monitoring wells will be positioned northeast and northwest of the former UST (Figure 2). The proposed �-► well to the northeast of the former UST will be installed at the surface street grade level, and the two other proposed wells will be installed at the subgrade parking area level. 6
