materials will be ground, pulverized, shredded, screened, source separated, or otherwise processed alone or mixed with soil in a manner to provide a compacted material free of open voids when applied to meet the performance requirements as alternate daily cover. Processed C&D waste materials used as ADC shall be restricted to the following materials: rock, concrete, brick, sand, soil, ceramics, cured asphalt, lumber and wood, wood products, roofing material, plastic pipe, plant material when commingled from construction work, and fines derived from processing the above materials. These materials shall comply with a grain size specification by volume of 95 percent less than 12 inches and 50 percent less than 6 inches as determined by the LEA. The.0&D wastes are evenly spread over the active face in a minimum 6-inch lift and average compacted lift thickness of less than 18-inches using a dozer. The lift is compacted such that it is free of voids. If voids are present, an approximately 2- inch layer of soil is spread over the C&D waste to eliminate voids. Contaminated Soil: Contaminated soil, suitable for use as ADC, (CS) is stockpiled close to the active face to facilitate application as daily cover. A large sign designates the area to unload the CS. The CS is spread over the active face using a dozer or loader in alternatirig layers approximately 6 inches thick. It should be noted that volatile organic compound (VOC) contaminated soil available for daily cover use is stockpiled separately. CS is also utilized for, but not limited too, preparation of wet weather deck or the improvement of the internal haul road and construction of earthen drainage control features. Furthermore, CS will also be utilized for beneficial reuse as allowed under 27 CCR, Section 20686. The amount of ADC used at the site is variable. The active face, over which ADC is placed, is kept as small as possible to reduce litter and vectors but large enough to allow safe and efficient traffic management. Daily ADC use could vary from 0 to 40 percent. The quantities of ADC used at the site will be recorded and maintained in the operations,record for the site. The forms used to record ADC use are included in Appendix M. If the site uses multiple types of ADC, the usage will be recorded by amount and type. Forward will continue to investigate other sources for daily cover materials, including those allowed in accordance with 27 CCR, Section 20690. As these ® types of ADC materials become available from the waste stream, Forward will Forward Landfill JTD 6-12 J:\Allied\ForwarduTD Amendment\Final JTD AmendmentUTD Sec 6 080105.doc:5/22/02 Rev.1:7/2002:Rev.2:4/2003;Rev 3:6/2003 BRYAN A.STIRRAT S ASSOCIATES Amendment No.1:8/1/2005
