day-to-day responsibility to observe cover placement work and to test and evaluate whether the cover is constructed according to specifications. 1.5 Estimate of Closure Date The landfill will be closed incrementally as each stage reaches final grades (see Section 1.2). As discussed in Section 1.2, the first staged closure project was split into two separate construction stages (i.e., Stage IA and Stage IB) with Stage IA closed in 2006. It should be noted that the base liner construction "Phases" do not correspond to the Closure Stages. In addition, the actual closure dates for each stage will depend primarily on the amount of refuse received over time, although operational factors and/or design considerations may also increase or decrease available air space which can also affect an individual staged closure date. Therefore, subsequent staged closure dates were not prepared for Stages II through VIII. Two years prior to reaching final fill elevation for each stage, a partial final closure plan will be prepared and submitted for review and approval from those regulatory agencies having jurisdiction over the FL. The overall site closure date is 2017. Stage VIII for the FL closure will be implemented at that time. 1.6 Site Security The FL is secured with perimeter fencing and locking gates. The FL is not open to the public so access to the staged closure areas will be limited to site personnel. The only foot, vehicle and/or equipment that will be allowed within the staged (partial) closure areas will be for post-closure monitoring and maintenance. 1.7 Post Closure End Use The post closure end use for the FL, which includes all staged closure areas, is non- irrigated open space. As the staged closure areas are completed, native vegetation will be planted which will provide erosion control. 1.8 Closure Cost Estimate In order to establish the basis for the proper level of funding for a landfill to be closed in increments over its active life, a closure sequence or staging plan must be prepared. Then, in order to meet 27 CCR requirements, the cost estimate must be based on the maximum extent or area of the landfill that would ever require closure. Since the FL is proposed to be closed in six stages, the basis of the closure cost estimate is the largest area requiring closure over the life of the landfill which, based on Table 1, is 187.6 acres. The active fill area will be maintained to an area equal to or less than this coverage area. As shown on Table 1, the maximum closure area will decrease over time. Therefore, the closure cost estimate can be reduced once Stage I is completed and again after Stage VII is completed. 7 Forward Landfill-PCPCMP Amendment (Z:\PROJECTS\Allied Waste\JN81013 5 yr Review Plan\PCPCMP Amend 3 July 08\Clos Amend 3 Final.doc; Amendment No.3:7/1/2008)
