UST REMOVAL <br /> On 11 March 2014, representatives of AGE and L&B Environmental uncovered and <br /> exposed the USTs identified; excavation and exploration was performed using an <br /> excavation equipped with a 36-inch bucket. <br /> The USTs were completely uncovered and exposed and soil was excavated from all <br /> sides of the tank and stockpiled on-site. The tanks were approximately three feet below <br /> surface grade (bsg). <br /> On 11 March 2014, the exposed USTs were inspected and no fuel was observed in the <br /> UST. The fuel was removed from the tank by pumping with a pneumatic pump <br /> recovered by a fuel vendor. <br /> 837 Shaw Road•Stockton,CA 95215 <br /> Telephone(209)467-1006•Fax(209)467-1118 <br />
