31 August 2012 <br /> AGE Project No. 11 -1847 <br /> Page 2 of 9 <br /> Each of these tasks is described in greater detail below. <br /> 2 . 1 . PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained , including boring/well permits from the <br /> SJCEHD . Also, a site-specific Health and Safety Plan will be prepared . Prior to <br /> mobilization , each soil probe location will be clearly marked and a utility clearance obtained <br /> through Underground Service Alert. The SJCEHD will be contacted 48-hours prior to <br /> conducting investigation activities to arrange for inspection . <br /> 2 .2 . SOIL PROBE BORINGS AND SAMPLING <br /> Initially, four soil probe borings will be advanced utilizing a direct push drilling rig to assess <br /> the lateral and vertical extent of the petroleum hydrocarbon-impact in the vicinity of the <br /> former UST areas (Appendix B data). A second set of borings may be advanced based <br /> upon analytical results of samples collected from the initial borings . <br /> Based upon data collected from the Quick N Save #2 site located at 2057 South EI Dorado <br /> Street, Stockton , California (northwest of the McBillin site) , ground water is inferred to be <br /> flowing toward the southeast/northeast; static groundwater depth within wells is estimated <br /> to be approximately 30 feet bsg . Locations of the soil borings are shown on Figure 2 and <br /> described below. <br /> Initially, the following locations will be evaluated : <br /> 1 <br /> • One soil boring will be advanced within the former underground storage tank area <br /> on the eastern edge of former locations of Tank #3 and Tank #4. Samples collected <br /> during the removal of the tanks documented impacted soil in this area at 10 feet arc <br /> below surface grade (bsg ). a'1•�" <br /> • One soil boring will be advanced at the northern edge of the former Tank #4 <br /> location , to evaluate the northern exent of adsorbed impact. ' <br /> • One soil boring will be advanced at the western edge of the former Tank#3 and <br /> Tank #4 locations to evaluate the western exent of adsorbed hydrocarbon impact. <br /> • One soil boring will be advanced near the northeastern edge of the former Tank #1 <br /> location . Samples collected during the removal of the tanks documented impacted <br /> soil in this area at nine (9) feet bsg (Appendix B). <br /> Advanced GeoEnvironmental, Inc. <br />
