CQA for Final Cover Placement The construction specifications include a CQA Plan for final cover placement. A geotechnical CQA crew, working under the direction of a Geotechnical Engineer, will be on-site full-time during the placement of the final cover to monitor compliance with project requirements. The CQA personnel will have 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 (spe`— T, _ Section 1.2). As discussed in Section 1.2, the first staged closure project wi# begin 'n 2006 and continue following the completion of each stage. It should be noted the base liner construction "Phases" do not correspond to the Closure Stage.`'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 as presented in the 2002 Closure Plan remains the same and will be the closure date for Stage VIII. 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 7 Forward Landfill-PCPCMPR (L:\Allied\2003.003 Western Region\FORWARD\PCPCMPR\FinalCPR.doc)
