5.0 CLOSURE/POST-CLOSURE MAINTENANCE COST ESTIMATE <br /> 5.1 INTRODUCTION <br /> In order to establish the basis for the proper level of funding to close and <br /> provide post-closure maintenance for the Forward Landfill in an <br /> environmentally sound manner, a cost estimate has been prepared reflecting <br /> the proposed closure design and post-closure maintenance procedures <br /> presented in Sections 3.0 and 4.0 of this PCPCMP. The estimate for closure <br /> improvements was combined with an estimate for construction <br /> management/quality assurance services to determine the total closure cost. <br /> 5.2 CLOSURE COST ESTIMATE <br /> As discussed in Section 1.4, the approved closure cost estimate for the site is <br /> based on the maximum extent of closure, which will ever require closure over <br /> the life of the landfill as allowed under 27 CCR. The closure cost estimate for <br /> the maximum extent of closure serves as basis to fund the closure account <br /> over the life of the landfill. The associated closure cost estimate reflects third <br /> party costs in 2008 dollars and is presented on Table 8. The maximum extent <br /> of area which will ever close over the course of the active life of the landfill is <br /> 187.6 acres. Allied is and will continue to closure the Forward Landfill in a <br /> number of smaller closure phases. The initial partial closure project was an <br /> area known as Stage 1A. A Partial Final Closure/Post-Closure Maintenance <br /> Plan (dated June 2005) for this stage was prepared and submitted to the <br /> regulatory agencies with closure activities being completed in 2005. <br /> 5.3 POST-CLOSURE MAINTENANCE COST ESTIMATE <br /> The post-closure maintenance cost estimate has been prepared utilizing <br /> information contained in Section 4.0 and estimates of manpower, materials <br /> and equipment to maintain the Forward Landfill in compliance with current <br /> applicable regulations. <br /> The total annual maintenance and monitoring cost estimate for post-closure is <br /> ® shown on Table 9. The costs shown on Table 9 include labor, equipment, and <br /> Forward Landfill PCPCMP 5-1 <br /> Z:\PROJECTS\Allied waste\Forward\JN81013 5 yr Review Plan\PCPCMP Amend 4 July 08\Section 5.doc <br /> Amend.No.4:8/7/08 <br />
