The soil treatment program was <br /> conducted in response to underground storage tank releases discovered at the site during the December 1996 <br /> tank removal and closure program. The soil treatment program was conducted in February 1997 by TPS <br /> Technologies of Richmond, California at the request and authorization of Amerco Real Estate Company/ <br /> U-Haul International, Inc. (Amerco/U-Haul). <br /> 1.1 BACKGROUND <br /> In December 1996, a tank removal team conducted a tank removal and closure program at U-Haul facility <br /> #709-83 located at 450 North Cherokee Lane in Lodi,California. The objectives of the tank closure program <br /> were to remove one 6,000-gallon underground gasoline tank,one 6,000-gallon underground diesel fuel tank, <br /> and the soil below the underground storage tank systems; and to close the underground storage tank system <br /> in accordance with the requirements of the City of Lodi and the Lodi Fire Department. <br /> The underground storage tank closure program involved obtaining tank closure permits from the City of Lodi <br /> and the Lodi Fire Department, rinsing, purging, excavating and removing the underground storage tank <br /> system,and backfilling and resurfacing the excavation. Soil samples were collected from below each tank. <br /> and from the soil stockpiles at the site in accordance with the City of Lodi and Lodi Fire Department <br /> requirements. Soil samples were transported to a certified independent analytical laboratory and analyzed <br /> for the constituents stored in the former tanks. <br /> The laboratory analysis indicated that the soil samples collected below the south end of the former diesel fuel <br /> tank and the north end of the former gasoline tank did not contain detectable concentrations of TPH or <br /> BTEX. The analysis indicated that the soil samples collected below the north end of the former diesel fuel <br /> tank and the south end of the former gasoline tank contained varied trace concentrations of TPH and <br /> Toluene,Ethylbenzene, and Xylenes,but did not contain concentrations of Benzene. <br /> `' 1 <br />
