5.2.4.4 PHASE 4 <br /> During refuse filling of Phase 3, excavation of Phase 4 will begin, and the site's <br /> main entrance and scalehouse facilities will be relocated to the Phase 5 area. <br /> Phase 4 is south of Phases 2 and 3. Activities will be conducted in the same <br /> manner as in the previous excavation. Liner and LCRS construction will occur <br /> just before Phase 3 and the existing permitted area currently occupied by the <br /> main haul road and scale facility reach waste capacity. <br /> 5.2.4.5 PHASE 5 <br /> During refuse filling of Phase 4, excavation of Phase 5 will begin. Phase 5 is the <br /> final excavation phase. The Phase 5 sequence is located south of the existing <br /> landfill and east of Phase 4. It should be noted that construction of Phase 5 as <br /> proposed includes the relocation of the South Creek, as described above. <br /> Activities will be conducted in the same manner as the previously excavated <br /> areas. Liner and LCRS construction will occur just before Phase 4 reaches its <br /> waste capacity. When completed, Phase 5 will reach the proposed final fill <br /> height within the expansion area. Figure F presents the proposed final contours <br /> for the existing permitted landfill and proposed expansion area. <br /> 5.2.4.6 PHASED CLOSURE OPERATIONS <br /> Phased closure of the landfill will be implemented throughout development of <br /> the FL. When a cell is filled to capacity and has reached final grades, it can be <br /> closed and capped with final cover. These areas will be closed in accordance <br /> with an approved Partial Final Closure Plan. Those areas which had not been <br /> closed at the end of active operation would then be closed in accordance with <br /> an approved Final Closure Plan prepared in compliance with applicable <br /> regulatory requirements in effect at that time. Currently, the lower portion of the <br /> north facing slope of the FL has been closed, as has the southern slope of <br /> WMU E (Eastern Ash Pit). A phased closure plan amendment was developed for <br /> the existing refuse footprint and and approved by the CIWMBT his plan will be <br /> modified to reflect the proposed expansion. <br /> Forward Landfill Project Description 5-6 BRYAN A.STIRRAT&ASSOCIATES <br /> (J:\Allied\Forward\2007.0018 Lateral Expansion\Reports\Prof Descrip\021308 Final Proj Des\Sec 5.doc:2/13/2008) <br />
