The Final Closure and Post-Closure Maintenance Plan for the Forward Landfill will <br /> include appropriate demonstrations that the engineered alternative final cover <br /> system meets or exceeds the requirements of 27 CCR, Section 21090 as required <br /> by 27 CCR, Section 21140. <br /> 5.2.4.3 SOIL AVAILABILITY <br /> Materials for construction of the final cover will be obtained from soils stockpiled <br /> during excavation of the WMUs or imported, if necessary. <br /> 5.2.5 FILL PHASING <br /> Class III waste is currently.,being..disposed,of.,in the previously filled area- ,of-the <br /> Austin Road Landfill. It is anticipated that the Class III waste will establish the <br /> base grades for the intermediate Class Il liner proposed above the currently fiied <br /> areas. Class III waste disposal operations will continue at the existing Austin <br /> Road Landfill to establish a 5 percent minimum gradient for the interim final <br /> cover per Detail 1 on Drawing 3. Additional Class l II waste will be placed-to the <br /> subgrade of the Class II intermediate liner, shown on Detail 3 on Drawing 6. A <br /> high point of 108 feet amsl slopes at 5 percent to the south and joins the"base <br /> grades for the future disposal area to the south of the existing Austin Road <br /> Landfill. <br /> The phasing shown on Drawing 5 is conceptual and actual phasing direction <br /> may vary. It is anticipated that each major phase of development depicted'in <br /> Drawing 5 for the Forward Landfill will consist of smaller fill sequences. <br /> Class II waste is currently being accepted at the existing Forward Landfill in <br /> WMU D-00 and D-01, within Phase 1 in Drawing 5, located in the northwest: <br /> portion of the existing Forward Landfill (west of lined WMUs D=97, D-98 and D- <br /> 99). Phase 2 located immediately north of Phase 1 is the next major fill phase to <br /> complete the Class II liner operations within the existing Forward Landfill permit <br /> boundary with the exception of the north access road and scalehouse area. The <br /> existing access road and scalehouse will continue to serve the future fill phases <br /> in the existing Austin Road Landfill to the west of the scales (Phases 3 through 7 <br /> shown on Drawing 5). <br /> Forward Landfill JTD 5-8 <br /> L:\AI lied\2000.193\Reports\f inalj td:sec-5.0:08/2 2/01 <br /> BRYAN A.STIRRAT S ASSOCIATES <br />
