• Page 3 <br /> 3 . Prior to processing contaminated material, the <br /> stockpiles will be flattened off so that the contaminated <br /> material can be recognized and kept separate from the <br /> uncontaminated material. After processing thru the mineral <br /> aggregate plant, the contaminated- material will be <br /> transported to separate stockpiles near the asphaltic <br /> concrete cold feed bins. The area where the contaminated <br /> material had been discharged from the mineral aggregate <br /> plant will be inspected to insure all material has been <br /> collected and placed in the separate piles. <br /> 4 . The contaminated mineral aggregate material will be <br /> made into asphaltic concrete by processing thru the <br /> asphaltic plant. (See Plate V) Material will be fed by a <br /> front end loader into the cold feed bins. The feeder then <br /> meters material onto a feed belt which carries it into the <br /> drum mixer. Asphalt oil is added at this point and the <br /> final asphaltic concrete is transported into storage silos, <br /> where it is loaded into trucks for shipment. <br /> . 5. Asphaltic Concrete made with the contaminated <br /> material will only be used on projects where groundwater is <br /> not near the surface. It is anticipated that the material <br /> will be used on roads in northern San Joaquin County, Amador <br /> or Calaveras Counties. A log will be maintained (See Plate <br /> VI) to record where asphaltic concrete containing <br /> contaminated material is used. A copy of the up to date log <br /> will be provided to Wm. J. Hunter and Assoc. to include in <br /> the final report to the S. J. PHS/EHD. <br /> 6 . Operations will be observed by Wm. J. Hunter & <br /> Associates. That firm will prepare a final report with a <br /> request for closure after the operation is complete. <br /> 7 . The schedule for this remediation procedure is as <br /> follows, and will commence within 2 weeks of County approval <br /> of the plan: <br /> Transport Material to Mineral Aggregate Plant - 2 days <br /> Process Material Thru MA Plant - 3 days <br /> Transport Material to Temporary Stockpile - 2 days <br /> Process Material thru AC Plant - Dependent on demand of <br /> product. Estimate all material should be used within 2 <br /> months of processing. <br />
