San Joaquin County <br /> July 28. 1992 <br /> Page 2 <br /> SCOPE <br /> The scope of this activity will include excavation and removal of the piping and the USTs. <br /> The three 10,000-gallon USTs will be inverted using dry ice and removed in accordance with <br /> SWRCB LUFT Field Manual. The tanks will be manifested and loaded immediately for <br /> transport and disposal by Erickson Inc., in Richmond,California. <br /> Once the tanks are removed from the excavation, two samples will be collected beneath each <br /> tank location and two composite samples will be collected from every 50 yards of excavated <br /> material. These samples will be analyzed using U.S. Environmental Protection Agency (EPA) <br /> Methods 8020 and 8015 for benzene, ethylbenzene, toluene, xylenes and total petroleum <br /> hydrocarbons (diesel). Since the tanks are within a fenced facility, the excavation will be <br /> flagged with construction tape and barricades to alert the employees working at the facility. <br /> All excavated material will be placed on, and covered with, plastic sheeting pending results <br /> from the laboratory. Upon receiving the results from the laboratory, the final disposal of this <br /> material will be determined for the excavated material. If off-site disposal of this material is i <br /> chosen, approval by the County will be acquired. <br /> Appendix A presents detailed descriptions for sampling from stockpiles and excavations, j <br /> sampling handling, and quality assurance plan. <br /> Appendix B presents the site safety and health plan to be implemented for this investigation. <br /> This plan meets CFR 1910.120 requirements for this type of activity. <br /> CONTRACTORS <br /> Armour Petroleum Service and Equipment Corporation, California General Contractors <br /> License #498721, Class A. <br /> L.
