Two areas measuring about 5,500 square feet (ftz) and 9,500 ft2 were excavated to <br /> depths of up to 38 feet below ground surface (bgs). The Report describes remediation <br /> activities performed at the Site between November 2009 and January 2010 that included <br /> the excavation, testing, segregation, sampling, disposal and stockpiling of clean and <br /> contaminated soil from two areas identified as former above ground storage tank (AGT) <br /> containment areas onsite along with the soil beneath a former pump island. <br /> Presently, 6,400 cubic yards of soil contaminated with total petroleum hydrocarbons as <br /> diesel (TPHd), ranging from 34 milligrams per kilogram (mg/kg) to 17,000 mg/kg, remain <br /> stockpiled onsite and covered with visqueen. Reportedly, clean overburden soil was used <br /> to fill the lower portion of both excavations to address instability issues. <br /> The Stockpile Remediation Work Plan proposes to remediate the diesel-contaminated <br /> stockpiles using a process developed by a bioremediation firm, Renovogen, that utilizes <br /> enhanced populations of select indigenous microbes to perform biodegradation. <br /> MARCOR proposes to till and redistribute the existing stockpile into a 6-foot high layer <br /> spread out over the Site. Boreholes, eight inches in diameter by 4.5 deep, will be drilled <br /> throughout the stockpile in grids that measure 15 feet by 15 feet to facilitate infiltration <br /> for every 50 cubic yards. In the initial stages of treatment, about 22,000 gallons of the <br /> microbe solution will be used to inoculate the stockpile through the infiltration galleries <br /> and through surface applications. Subsequent applications will consist of water every <br /> other day and the microbe solution every week. <br /> California Environmental Protection Agency <br /> �d Replied Paper _ <br />
