April 2013). The base liner will encompass approximately 4.2 -acres and will extend approximately 350 feet in the north -south dimension and 750 feet in the east -west dimension. The base of WMU FU -13 at the top of clay liner will range from approximately elevation 7 -feet to 13 -feet, which is about 22 to 28 feet below the surrounding ground surface. A composite lining system consisting of a 2 -foot -thick clay liner overlain by a 60 -mil, high-density polyethylene (HDPE) geomembrane, and LCRS consisting of 1 foot of granular drainage material will be constructed on the WMU FU -13 base. HDPE leachate tanks will be placed at the eastern edge of the WMU FU -13 base, from which leachate will be pumped and removed. Side slope liners will be constructed on the northern slope. The side slope liner on the north slope consists of a geosynthetic clay liner (GCL) overlain by a 60 -mil, single -sided textured, HDPE geomembrane, and a single -sided geocomposite drainage net (GDN). A portion of the northern WMU FU -13 slope is at an approximately 4.5:1 (horizontal to vertical) slope and is underlain by the former Austin Road Landfill. To provide support for the side slope liner, an approximately 4 to 5 -ft thickness of subgrade fill (1 -ft of subgrade fill was previously placed as intermediate cover over the former Austin Road Landfill) will be placed and compacted over the portion of the former Austin Road Landfill that underlies WMU FU -13. A liner and leachate collection system was constructed on the top deck of the former Austin Road Landfill as part of the Northern Portion of WMU FU -08 construction. Leachate from the lined WMU FU -08 North top deck area currently drains through a series of pipes to a leachate tank. The portion of WMU FU -13 that intersects WMU FU -08 North will be connected to WMU FU -13 so that the leachate from this portion of the top deck can drain directly into WMU FU -13. Class III Refuse placed in the northern portion of WMU FU -08 will be separated from the Class II refuse that can be placed in WMU FU -13 by placing Class III refuse a minimum of 50 -ft south of the northern/southern boundary of the cell, thereby providing sufficient separation. 1.3 Reference Documents The following reference documents provide background information and support this CQA manual: WMUFU--13 Design and Construction Documents, Forward Landfill, Lewis Engineering, April 2013.
