• <br /> Treadwell&Rollo <br /> each of the three sites with a 4-inch thick asphaltic concrete cover is $4.00 per square foot. This <br /> assumes that minimal grading and site preparation is required. Annual maintenance, which <br /> consists of visual observation and cold-patching of cracks is estimated to be $2,000 per site. <br /> Using the $4.00 per square foot unit cost, the costs (not including annual maintenance)to cap <br /> Areas 10, 11, and 21 are $872,000, $480,000, and $180,000, respectively. <br /> On-site relocation and capping combines site remediation with site redevelopment activities. <br /> Therefore, the cost of the remediation is a combination of the premium associated with handling <br /> contaminated soil, and associated maintenance costs. A reasonable estimated premium to handle <br /> contaminated soil is $2.00 to $3.00 per cubic yard. The total cost of on-site relocation and <br /> capping is dependent on the total yardage moved, which will be a function of specific <br /> development plans. <br /> Excavation and off-site disposal costs will vary, depending on the type and level of <br /> • contamination, the total volume of soil involved, and the landfill to which the soil is transported. <br /> Each landfill has specific acceptance criteria which can vary. Current landfill disposal costs are <br /> listed as follows: <br /> Facility Class Disposal Costs <br /> Altimont Landfill, Livermore II Non-Hazardous $25 —$30 per ton <br /> Vasco Road, Livermore <br /> Forward, Manteca <br /> Kettleman, Kettleman City I,Non-RCRA Hazardous $65 —$70 per ton <br /> Button Willow, Button Willow <br /> Kettleman, Kettleman City 1, RCRA Hazardous $150—$160 per ton <br /> Button Willow, Button Willow <br /> • <br /> 27 <br /> 25970318.PGS 15 November 2000 <br />
