PROPOSED CORRECTIVE ACTION RECEIVED <br /> for MAR O 1 1995 <br /> 2360 East Street at Grant Line Road, TracyNvONMENTAL ALTH <br /> Executive Summary <br /> EPM Technologies of Modesto wishes to move approximately 40 <br /> cubic yards of previously excavated soil containing 16 to <br /> 150 parts per million Total Oil and Grease from the former <br /> gas station at 275 Grant Line Road, Tracy across the <br /> intersection of Grant Line and East Streets to 2360 East <br /> Street . . .property that is also a former gas station site. <br /> Both properties are owned by the Pestana Family Trust . <br /> The soil was excavated during an environmental investi- <br /> gation performed at the request of the San Joaquin County <br /> Department of Public Health Services . The type and level <br /> of contamination present in the soil has been confirmed by <br /> sampling and laboratory analyses performed according to <br /> established regulatory agency protocol . Moving the soil <br /> will permit it to be treated at a location further from the <br /> apartment buildings located next to 275 Grant Line Road. <br /> The corrective action clean-up that has been proposed will <br /> involve the moving of the contaminated soil across Grant <br /> Line Road to 2360 East Street by truck. The soil will then <br /> be placed atop bermed, 6-mil polyethylene sheeting and <br /> treated using common soil bacteria known to degrade oil . <br /> The treatment process, known as bioremediation, involves <br /> mixing the soil with compost , adding commercial fertilizer, <br /> watering the soil , and keeping it well oxygenated by <br /> drawing air through the soil with a vacuum pump. The soil <br /> will be loosely covered with plastic sheeting. Naturally <br /> occurring soil bacteria will then degrade the contaminants <br /> within the soil to form the non-toxic end products of <br /> carbon dioxide, minerals, and water. <br /> The site will remain fenced and the soil will be kept <br /> sufficiently moist with a sprinkler system constructed of <br /> PVC pipe to prevent dust blowing into the shopping center <br /> located adjacent to the treatment area. The treatment <br /> process is expected to take approximately 30 days . <br />
