The site is located on the east side <br /> ` of the existing Southern Pacific track near the intersection of Union <br /> Street and East Scotts Avenue in Stockton (Figure 1-1). The new <br /> property line was discovered to bisect an underground vault and a <br /> storage t nk. In December, 1987, Cal Tank Testing removed the tank <br /> and vault. During the removal operation, two more tanks were ' <br /> discovered. All three tanks had contained heavy fuel oils which <br /> presumably Fere used to fire boilers ata Del Monte Cannery facility <br /> which had previously occupied the adjacent site. The former <br /> locations of the vault and tanks are shown in Figures 1-2 and 1-3. <br /> The vault was constructed of concrete and measured 10 ft by 50 ft by 6 <br /> ft. Tanks # 1, 2, and 3 had capacities of 2500, 8000, and 6000 gallons, <br /> respectively. All three tanks were of single-walled steel construction. <br /> Cal Tank Testing estimated the tanks to be more than 30 years old. <br /> During the ramoval of tanks # 2 and # 3, it was found that these two <br /> tanks had leaked an unknown amount of product through holes in <br /> the tank wails.
