9-P This section describes the operation of the N p CSL. C -• e landfill will be constructed by the ramp -area method. Refuse fill will be placed in lifts approximately 6 to 10 feet thick, with perimeter slopes of 3:1 (horizontal to vertical) or flatter. Refuse will be spread and compacted in layers approximately 2 feet thick on a sloped working face. Except for the initial lift in each landfill module, wastes will be deposited at the base of the working face, spread up the face and compacted. The compaction equipment will traverse the entire length of the working face and make several passes over each refuse layer so that all waste is adequately compacted. Large or bulky wastes will be sepa- rated to prevent bridging of the surrounding refuse, placed in the lower portion of the advancing lift, and thoroughly crushed by compacting equipment. The ad- vancing face will be covered daily with a minimum 6 -inch -thick soil cover. When additional waste materials will not be placed over the surface within 180 days, the top and side slopes of the advancing lift will be covered with a minimum 12 -inch - thick layer of intermediate soil cover. A four -working -face two -lift placement method, shown on Drawing 3, will normally be used to place refuse fill at the site. Generally, only one face is actually open at a time. This method maximizes the service life of haul roads. An all-weather haul road will be constructed from the access road across the surface of the ex- isting refuse fill to the active working area. An initial working refuse face is then advanced on one side of the all-weather haul road toward the access road. A second working refuse face is advanced adjacent to the first over the all-weather access road. During the dry months, a ramp is constructed from the haul road to the surface of the lower lift. Refuse vehicles are routed over the soil cover, and an upper lift is filled by advancing the third and fourth working faces. An ade- quate distance will be maintained between the toe of the upper lift and the top of the ramp to provide a truck maneuvering area for advancing the third and fourth working faces.
