Construction of the remainder of the northern portion of WMU FU-06 consists of placement of a 6- <br /> inch thick blanket LCRS composed of granular drainage material with perforated piping spaced at <br /> approximately 200-ft centers. The blanket LCRS is both underlain and overlain by an 8-ounce <br /> nonwoven geotextile. A 1-ft protective operations layer overlies the blanket LCRS. <br /> Leachate in the northern portion of WMU FU-06 is routed through 3-inch perforated pipes and <br /> collected along the southern top deck boundary of the former Austin Road Landfill. The cell is <br /> bounded by lined perimeter berms on the north, south, and east sides to maintain leachate within the <br /> cell. The western side of the northern portion of WMU FU-06 will be connected to WMU FU-05. <br /> Leachate exits the cell in a 3-inch diameter leachate header pipe that will route the leachate to a <br /> temporary leachate tank. <br /> Once the southern portion of WMU FU-06 is approved by the RWQCB for disposal, the liner and <br /> LCRS systems in the northern and southern portions will be connected. In addition, Class III refuse <br /> will be placed in the northern portion of WMU FU-06. The south facing slope of refuse placed in the <br /> northern portion will be lined with an interface liner to separate the Class III refuse in the northern <br /> portion from the Class II refuse in the southern portion. The interface liner will consist of a minimum <br /> 4-ft thickness of subgrade fill overlain by a GCL, 60-mil HDPE geomembrane, and a geocomposite <br /> drainage net The geocomposite drainage net will overlap the northern slope of the southern portion <br /> of WMU FU-06 to allow leachate to drain to the WMU FU-06 base and sump. <br /> WMU FU-06 1-3 <br />
