EXECUTIVE SUMMARY %�we <br /> Underground Storage Tank Removal and Soil Over-excavation Project <br /> enviros® <br /> Shell Service Station <br /> 420 W. Kettleman Lane <br /> Lodi, California <br /> Site Background <br /> The site is an active retail gasoline service station located on the southeast corner of Kettleman Lane and Hutchins <br /> Road in a commercial area of Lodi. The existing facilities include a station building with car wash facility, five <br /> dispenser islands, and three underground storage tanks. <br /> Previous environmental activities have included drilling of 15 soil borings in 1989, installation of three ground <br /> water monitoring wells in 1990, and drilling of one soil boring and installation of one ground water monitoring <br /> well in 1995. <br /> Site closure was granted by the Central Valley Regional Water Quality Control Board in July 1996. <br /> Scope of Work for Current Underground Storage Tank Removal and Over-excavation Project <br /> The current project includes removal of the three existing USTs and associated product piping, and replacement <br /> with two double-wall fiberglass USTs and double-wall fiberglass product piping. This work is performed to <br /> upgrade the USTs and piping system to comply with construction standards required by 1998. <br /> The USTs will be uncovered and rinsed, and flammable vapors will be rendered inert. The tanks will be removed <br /> and loaded onto trucks for removal from the site. <br /> Tank and Rinsate Hauler: Destination of Tank Rinsate: Destination of Tanks: <br /> Crosby and Overton, Inc.

The volume of soil which may be excavated will depend on field <br /> conditions. <br /> Soils excavated from the tank pit and product line trenches, and any potential over-excavation soils will be <br /> stockpiled on-site. After appropriate sampling is performed, the soil will be transported to Forward Landfill for <br /> disposal. Soil hauling will be performed by Manley and Sons Trucking. Any ground water removed from the <br /> excavation will be transported to Shell's Martinez Manufacturing Complex in vacuum trucks provided by <br /> Allwaste. <br /> After removal of the USTs, existing product piping, and soil, new USTs and product lines will be installed. <br /> This project is scheduled to begin on November 18, 1996, and be completed by December 27, 1996. The <br /> corrective action and soil removal phase is scheduled to be completed by December 6, 1996, followed by <br /> installation of the new USTs and lines, and completion of construction. <br /> Site Status at Completion of Project <br /> Upon completion of the project, the site will re-open as a Shell service station. The UST and piping systems will <br /> have been upgraded to meet standards required by 1998. <br />
