Treated Auto Shredder Residue (18" assumed -Title 3.1:1 <br /> 27 requires an average compacted thickness less than <br /> 24" <br /> C&D (Inert) Material(12"assumed -Title 27 requires 4.7:1 <br /> an average compacted thickness less than 18" <br /> Ash and Cement Kiln Dust 12"thick 4.7:1 <br /> NOTE: Thickness shown above are consistent with Title 27,Section 20690 <br /> Predominately, Forward Inc. utilizes soil (both clean and contaminated), PGM <br /> and TASR. Volume calculations performed to estimate the above ratios for <br /> materials, other than soil, are included in Appendix C-1. As noted in Section <br /> 4.3.1, discussions with the LEA resulted in the conclusions that ash and cement <br /> kiln dust are believed to have similar properties to PGM, and that C&D material <br /> is believed to have properties similar to treated auto shredder residue. <br /> However, based on the refuse to cover ratios listed above, Forward Inc. will use <br /> an effective refuse-to-cover ratio of 4:1 for purposes of calculating the landfill's <br /> remaining capacity and site life. In addition, the remaining waste capacity and <br /> site life are reviewed annually by Forward Inc. and are required to be updated in <br /> accordance with 27 CCR, Section 21640, in conjunction with a review of the <br /> solid waste facilities permit every five years. <br /> 4.6 SITE CAPACITY <br /> As previously discussed, the disposal area footprint consists of approximately <br /> 387.8 acres. The total site capacity is based on the difference between the <br /> estimated subgrade excavation and the final disposal area contours. The total <br /> remaining airspace for the Forward Landfill, as of January 2006, is 30.03 million <br /> cubic yards (mcy) (date of last aerial survey was February 2005). Appendix C <br /> presents information regarding air space, final, intermediate and daily cover <br /> requirements and remaining refuse capacity. The remaining site life is based on a <br /> refuse to soil volume ratio of 4:1 and a refuse density of 1,740 pounds per cy (or <br /> 0.87 tons per cubic yard). This refuse density results from a calculation using (1) <br /> the September 15, 1999 aerial topographic map of Forward Landfill, (2) the <br /> October 6, 2000 aerial topographic map of Forward Landfill, and (3) the total tons <br /> Forward Landfill JTD 411 <br /> J:\Allied\Forward\JTD Amendment\ianuary2006 JTD Amendment\JTD Sec 4 012506 Accept.doc: <br /> 05/24/02;Amendment No. 1: 1/27/2006 BRYAN A.sTIRRAT 8.wss®ctnrEs <br />
