over the northern, eastern, and western sides of WMU in 1999 and 2000 to <br /> separate the ash from designated waste that would be placed above it. A final <br /> cover was placed on the southern side in 1999. <br /> WMU F North is an approximately 1-acre leachate impoundment located just <br /> north of the South Branch of Little Johns Creek on the western side of the site. <br /> WMU F North was constructed in 1999 as a double lined unit and contains a <br /> GCL overlain by a 60-mil HDPE geomembrane, a geonet, and an additional <br /> 60-mil HDPE geomembrane. The leachate impoundment was sized based on <br /> actual leachate generation records from 1991 to 1997 and has a design capacity <br /> of approximately 3.5 million gallons. <br /> Soil treatment and sludge drying is permitted to occur in WMU G. WMU G is <br /> divided into G-North and G-South, according to whether they are north or south <br /> of the South Branch. WMU G occupies the same areas as WMUs Future D <br /> and H, and will eventually be replaced by these units. Forward has not been <br /> treating soils or drying sludge during the last several years. If these activities <br /> were to occur, appropriate lining systems would be installed. <br /> The existing portion of the Austin Road Landfill encompasses a 123.9-acre area <br /> located directly south of the North Branch of Little Johns Creek, as shown on <br /> Figure 10. The landfill began accepting municipal solid wastes in 1954 and does <br /> not contain a base liner or leachate collection and removal system (LCRS). <br /> Wastes were initially landfilled utilizing the trench method. Trenches have been <br /> excavated to an approximate 20-foot depth with the excavated materials used <br /> for daily cover. <br /> Future Permitted Waste Management Units <br /> As depicted in Figure 10, future Class II WMUs are permitted in the remaining <br /> portions of the northern (Future D) and southern portions (Future H) of the <br /> existing Forward Landfill. The southern portion of the existing Austin Road <br /> Landfill is also permitted as WMUs, however these areas are currently permitted <br /> as Class II units. <br /> WMU F South is currently permitted to be constructed in the southwest corner <br /> of the existing Forward Landfill, south of the South Branch of Little Johns Creek. <br /> WMU F South is permitted as a Class II impoundment. <br /> Forward Landfill JTD 4-3 <br /> J:\Allied\Forward\JTD AmendmentUanuary 2007 JTD Amendment\JTD Sec 4 Final.doc: <br /> 05/24/02;Amendment No. 1: 2/6/2007 ®avant A.STtRaaT a ASSOCIATES <br />
