Therefore the alternative final cover design for the Forward Landfill will <br /> consist of the following: <br /> • A one-foot thick foundation layer composed of select soil materials, a one <br /> foot (±) is in-place as interim cover. The depth of the interim cover will be <br /> verified and additional cover will be placed to achieve the one-foot <br /> thickness. <br /> • A three-foot thick layer of select soil material that will comprise the upper <br /> monolithic cover layer. <br /> A typical cross-section of the proposed alternative final cover system is <br /> shown on Detail 1 of Drawing Sheet D-1. <br /> The alternative final cover configuration has been designed to: <br /> • Ensure the containment of waste materials; <br /> • Minimize the infiltration of water from rain and provide a vegetative cover <br /> of native shrubs and grasses; <br /> • Prevent exposure of people and animals to waste; <br /> • Limit landfill gas emissions; <br /> • Minimize odor; <br /> • Control fires; and <br /> • Provide for an aesthetically pleasing appearance. <br /> The final cover was designed by a certified engineering geologist in <br /> accordance with State and Federal regulations and will be constructed in <br /> accordance with this PFCPCMP. Closure activities will commence upon <br /> approval of this PFCPCMP. <br /> 3.2.2 FINAL COVER CONSTRUCTION <br /> Clearing and Grubbing <br /> Prior to final grading and placement of the final cover, all existing vegetative <br /> materials will be removed from the surface without disturbing the underlying <br /> refuse. All deleterious materials generated by the clearing and grubbing <br /> operation will be disposed in the active portions of the landfill. The <br /> segregated soils will be used to construct final cover. <br /> Forward Landfill PFCPCMP 3-4 <br /> Z:\PROJECTS\Allied Waste\Forward\Reference Files Prior JTDWune 05 Stage IA Partial FCPCMP\FL-sec3.doc:6/16/2008 <br />
