waste materials used as ADC shall be restricted to the following materials: rock, <br /> concrete, brick, sand, soil, ceramics, cured asphalt, lumber and wood, wood <br /> products, roofing material, plastic pipe, plant material when commingled from <br /> construction work, and fines derived from processing the above materials. These <br /> materials shall comply with a grain size specification by volume of 95 percent <br /> less than 12 inches and 50 percent less than 6 inches as determined by the LEA. <br /> The C&D wastes are evenly spread over the active face in a minimum 6-inch lift <br /> and average compacted lift thickness of less than 18-inches using a dozer. The <br /> lift is compacted such that it is free of voids. If voids are present, an <br /> approximately 2-inch layer of soil is spread over the C&D waste to eliminate <br /> voids. (NOTE: Certain types of C&D, primarily asphaltic concrete and Portland <br /> cement concrete, are diverted from disposal for other beneficial uses, such as <br /> roads and tipping decks.) <br /> Contaminated Soil: Contaminated soil, suitable for use as ADC, (CS) is <br /> stockpiled close to the active face to facilitate application as daily cover. A large <br /> sign designates the area to unload the CS. Forward Landfill uses CS as ADC <br /> (and as alternative intermediate cover) in the same manner as regular soil. The <br /> CS is spread over the active face using a dozer or loader in alternating layeFs <br /> to provide a minimum thickness of 6 inches of daily <br /> cover over refuse fill (12 inches of intermediate cover). It should be noted that <br /> volatile organic compound (VOC) contaminated soil available for daily cover use <br /> is stockpiled separately. <br /> ICS is also utilized for, but not limited too, intermediate preparation of wet <br /> weather deck or the improvement of the internal haul road and construction of <br /> earthen drainage control features. Furthermore, CS will also be utilized for <br /> beneficial reuse as allowed under 27 CCR, Section 20686. <br /> The amount of ADC used at the site is variable. The active face, over which <br /> ADC is placed, is kept as small as possible to reduce litter and vectors but large <br /> enough to allow safe and efficient traffic management. Daily ADC use eeuld <br /> The quantities of ADC used at the site will be <br /> recorded and maintained in the operations record for the site. The forms used <br /> to record ADC use are included in Appendix M. If the site uses multiple types of <br /> ADC, the usage will be recorded by amount and type. <br /> Forward will continue to investigate other sources for daily cover materials, <br /> Forward Landfill JTD 6-12 <br /> J:\Allied\ForwardVTD Amendment\January2006 JTD Amendment\JTD Sec 6 012506 Track Changes.doc: <br /> 5/22/02;Rev.1:7/2002:Rev.2:4/2003;Rev 3:6/2003;Amendment No.1:1/26/2006 <br />
