The stockpiled <br /> soil was reported to have been aerated and resampled until levels of less than 100 ppm TPH- <br /> i g was achieved. The soil was subsequently transported and disposed of at the Jackson Road <br /> 1 Landfill in Sacramento County. <br /> 11-29-88 Proposition 65 Notification of Hazardous Waste Discharge #88-222 filed this date.
