WMUs FU-03, FU-04, FU-05, and FU-06 are located directly south of the former <br /> Austin Road Landfill. The southern portion of these WMUs is permitted to <br /> receive designated wastes. These units were constructed to meet prescriptive <br /> Class II regulatory requirements for base liners and LCRSs and contain the same <br /> system described above for WMUs D-93 to D-02. <br /> The northern portion of WMUs FU-03 to FU-06 overlies the top deck of the <br /> former Austin Road Landfill. Only Class III refuse is permitted to be placed <br /> above the top deck of the former Austin Road Landfill. An LCRS was added to <br /> the top deck final cover to allow leachate from the refuse placed above the top <br /> deck to drain into the Class II WMUs to the south. The liner and LCRS system <br /> for the refuse placed on the top deck consists of (from top to bottom): <br /> • 1-ft thick Operations Layer <br /> • Filter Geotextile <br /> • 0.5-ft thick granular drainage material with dendritic LCRS pipe system <br /> • Filter Geotextile <br /> • 1-ft thick Vegetative Layer (part of final cover with vegetation stripped) <br /> • 1-ft thick low permeability layer (permeability less than 1 x 10-6 cm/sec) <br /> ® 2-ft thick foundation layer <br /> Interface liners are placed to separate the Class II refuse in the southern portion <br /> of WMUs FU-03 to FU-06 from the Class III refuse located in the former Austin <br /> Road Landfill. The interface liners consist of the same components described <br /> above for WMU D-94. <br /> 4.1.2 FUTURE PERMITTED WASTE MANAGEMENT UNITS <br /> During the winter of 2007/2008 refuse fill operations were proceeding in the <br /> FU-06 refuse cell located in the northern portion of the site. Placement of the <br /> next lift of waste will then proceed west toward FU-03. FL currently plans to <br /> continue constructing cells and filling the northern portion of the site to capacity <br /> before moving the operation to the area south of the South Creek. <br /> Forward Landfill- Project Description 4-4 BRYAN A.STIRRAT&ASSOCIATES <br /> (J:\Allied\Forward\2007.0018 Lateral Expansion\Reports\Prof Descrip\021308 Final Proj Des\Sec 4.doc:2/13/2008) <br />
