Construction Management A construction management team will be on-site during the entire period of closure construction. The team will be under the direction of a Construction Manager, who will supervise construction of the various features included in the closure plan. The Construction Manager will coordinate the activities of the on-site contractor(s) and will provide liaison among Allied staff, the design engineers and the contractors. Other key staff may include a Site Engineer and Construction Inspector(s). A survey crew and a geotechnical CQA crew will be present, as required. Survey Control The survey control crew, under the direction of Allied, will be responsible for the surveyed location of the closure plan improvements and for record drawing information. They will be responsible for documenting that the various components of the cover conform to the grade and/or thickness requirements of the construction drawings and specifications. 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 (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 113) with Stap-e 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. a-resented iR the 2002 IE)S Fe Pan r the same and will be the elasui:cdte f9F Stage Vlll for the FL closure will be implemented at that time. 7 Forward Landfill-PCPCMP Amendment (Z:\PROJECTS\Allied WasteVN81013 5 yr Review Plan\PCPCMP Amend 3 July 08\FinalCPRRev1.doc; Amendment No.3: )
