2.0 DESCRIPTION OF PII.E CONFIGURATION AND PHASING <br />2.1 Final Unner Refuse Pile Confieuration <br />The final URP configuration, which maximizes storage and will yield a <br />stable configuration, is shown in Figure 1.0. The design utilizes an overall <br />average slope, including benches, of 2.5H to 1V to a maximum pile height of _ _ <br />235 feet. The pile shall be constructed in 40 feet high stages, with 50 feet wide <br />benches along the perimeter of each stage. A conveyor system shall serve as <br />the principle means for moving the refuse from the screening plant to the URP. <br />Access to the pile shall be from the northwest, along a proposed road that <br />extends from the ridge immediately west of the WEM water tank and climbs <br />toward the east above the water tank. The haul road design will allow a road <br />of a minimum width of 24 feet to be utilized for the entire life of pile <br />construction. <br />Volume capacity for refuse material is estimated to be 7.6 million cubic <br />yards, including a required average of 18 to 24 inches of soil cover to be placed <br />over the final layout. The density of the refuse material, compacted to 90 <br />percent of the maximum dry density (method ASSHTO T99-74), is <br />approximately 85 pcf. At this density, the volume of refuse material is <br />estimated at 8.7 million tons. <br />Topsoil and subsoil shall be salvaged and either stockpiled or placed <br />directly on the surface of pre-completed buildout phases (Section 2.2). Ditches <br />to handle sediment and clear water runoff shall be constructed as shown on <br />Figure 2.0. Sediment runoff will be directed into an existing ditch located east <br />of the main portals and routed into MB-1. The ditches are designed to carry <br />a 100-year, 24-hour storm event (Section 6.2). <br />2 <br />
