EXECUTIVE SUMMARY <br /> T &T TRUCKING,INC. CLEANUP PROGRAM <br /> I <br /> July.20, 2007 <br /> T&T Trucking, Inc. (Site)'is located at 11396 North Highway 99 just south of Lodi, California. <br />` Gasoline was stared at the Site in a former 4,000 gallon underground storage tank. On February 20, <br /> 1995, a 970-gallon release was reported during inventory monitoring (it had leaked underground <br /> from the tank); the remaining fuel was removed from the,tank the same day as the release. <br /> Investigation and cleanup 4-the Site is being conducted,under the supervision of the San Joaquin <br /> County Environmental Health Department (County). <br /> Subsequent tank removal, soil excavation, and site investigations were conducted at the Site. Four <br /> groundwater monitoring wells installed at the Site and one drinking water supply well are tested <br /> Eevery three months. Gasoline-related contaminants have never.been found in samples from the. <br /> private supply well. <br /> In February 2007, a soil vapor extraction and air sparge (SVE/AS) remediation design was approved <br /> by the County and will be implemented at the Site to clean up the soil and groundwater. In <br /> summary, clean air is bubbled into the groundwater to vaporize the gasoline and then gasoline <br /> E R <br /> vapors are sucked out of the ground to either be burned or filtered;removing the contamination <br /> from the air stream before it is released into the atmosphere. The air that is released into the. . <br /> I atmosphere is clean and safe to breath'and is permitted by the San Joaquin Valley Air Pollution <br /> Control District. <br /> T&T Trucking, Inc. is planning to begin construction of the remediation system in late summer <br /> 2007 and is expected to run continuously for about one year.The system willhave some noise from <br /> the equipment similar to a leaf blower but operations will not impact nearby neighbors. <br /> 3' Groundwater testing from the Site monitoring wells will continue every three months during <br /> operation of the treatment system and for one year after it is turned off to monitor the <br /> I <br /> I concentrations of gasoline andMtBE contamination. The Site will continue to be a trucking <br /> company throughout operation of the treatment system and after the cleanup has been finished. <br /> CADoeuments and Settings\minfurna\Local Settings\Temporary Internet Files\OI.KI\F',Xecuticc Surnmary.doe <br />
