1-8 <br /> thick monolithic (ET) alternative final cover section composed of on-site soils will satisfy the <br /> regulatory requirements for an alternative final cover as defined in 27 CCR. A traditional <br /> barrier layer is not proposed for the alternative final cover design. The 2013 Joint Technical <br /> Document (JTD) includes the Final Cover CQA Plan (GLA, 2005) and an Alternative Final Cover <br /> Design Report (GLA, 2005) as appendices. The cost of constructing the final cover includes <br /> site preparation, site grading, final cover placement and settlement monument installation. <br /> 1.8.2 Final Cover Construction Ouality Assurance Monitoring and Testing <br /> The costs for CQA include the final cover placement tests, inspections, and reporting. As <br /> mentioned above, the Final Cover CQA Plan (GLA, 2005) is included as an appendix to the <br /> 2013 JTD. <br /> 1.8.3 Drainage Control System <br /> The costs for the drainage control system include the construction, removal, and <br /> replacement of inlet structures and down drains over an approximate 187-acre area. <br /> Construction of the permanent drainage control system for the current fill area is complete. <br /> As operations expand, the drainage control facilities for the upcoming fill area are installed <br /> concurrent with liner construction, as part of ongoing landfill development. No costs for <br /> drainage construction, other than for final closure items, are included in the closure cost <br /> estimate. <br /> 1.8.4 Landscaping and Erosion Control <br /> This category covers the cost of landscaping construction, which includes soil preparation <br /> and planting of vegetative materials. <br /> 1.8.5 Gas Control System <br /> This category includes the cost of extending the wells through the final cover and lateral <br /> piping system modification during placement of the final cover system. <br /> 1.8.6 Site Security <br /> This category includes costs for required signage at closure of Stage VI or any lesser portion <br /> of the site. The site is currently enclosed with a perimeter fence and gates or has <br /> topographic constraints to prevent unauthorized access to the site property. <br /> 1.8.7 Structure Removal/Decommissioning of Environmental Control Systems <br /> This category generally includes costs for dismantling and removal of on-site structures (i.e., <br /> fee booths and landfill scales). No costs have been included for decommissioning of the <br /> environmental control systems since none is planned at this time. <br /> 1.8.8 Gas Migration Monitoring System <br /> This category assumes that all gas migration monitoring probes will be placed during active <br /> operations as required under 27 CCR, Sections 20921 through 20939. <br /> Forward Landfill SWT Engineering <br /> PCPCMP Amendment No.4-May 2013 <br /> z:\projects\allied waste\forward\five year permit rvw 2013\jtd-5 yr pr 2013\appendices\app a-pcpcmp 2013\pcpcmp amend 2013.doc <br />
