DTSC is proposing to approve a RAP for the Former Oroville Manufactured Gas Plant site pursuant to regulatory authority granted under chp. 6.8, div 20, sec 25323.1 and 25356.1, H&SC. The draft RAP will address impacts to soil and groundwater from previous operations at the site. The remedial activities will involve excavation and disposal of approx 6,600 cy, or approx 430 truckloads, of contaminated soil at an off-site permitted facility. The soil is impacted by benzene, polycyclic aromatic hydrocarbons, lead, and petroleum hydrocarbons. Additionally, approx the same amount of clean fill will be imported from a local source. Imported soil will be tested for contaminants in accordance with DTSCs October 2001 Information Advisory on Clean Imported Fill Material. The Site consists of a portion of the City paved parking lot located on a block bounded by Myers, Montgomery, and Huntoon streets in Oroville, CA. The Site is bounded to the west by Huntoon Street, to the north by a levee for the Feather River, and to east and south by other portions of the parking lot which extend to Meyers Street and Montgomery Street, respectively.
