Geosyntec Consultants <br /> • Existing 59 acre Class I landfill consisting of Segments 1 and 2, and an <br /> Infill. <br /> • Existing 22 acre unlined C&D landfill (Cell 1 ) <br /> • New 33 acre unlined C&D landfill (Cell 2), permitted and under <br /> construction <br /> • New 44 acre lined Class I landfill (Segment 3 ) being designed and <br /> permitted <br /> The existing Class I landfill is active and presently accepts for disposal both C&D <br /> debris and MSW. The C&D debris is placed on the side slopes and top of the unlined <br /> Segment 1 . MSW is placed on the side slopes and top of the lined Segment 2 and the <br /> infill . Under the separate disposal scenario, Segments 1 and 2 and the Infill of the <br /> existing Class I landfill and Cell 1 of the C&D landfill are expected to provide all the <br /> disposal capacity needs of the County through 2010. Thereafter, Class I waste will be <br /> landfilled in the lined Segment 3 and C&D debris in the unlined Cell 2. Two additional <br /> infills are also proposed between Segment 3 of the Class I landfill and each of the two <br /> C&D landfill cells to maximize the disposal capacity of the site (see Figure 2). The two <br /> infills are planned for construction and operation as Class I landfills and projected to <br /> provide 6-year of additional disposal capacity for the County. Cell 2 has a projected <br /> useful life of 18 years compared with the 26 year capacity projected for Class I landfill . <br /> Further disposal of C&D debris, after the completion of Cell 2, will have to be in a <br /> Class I landfill commingled with MSW. <br /> Under a codisposal scenario, Cell 2, presently scheduled for operation as a C&D <br /> landfill, will be integrated into Segment 3 and constructed as a Class I landfill . Once the <br /> existing C&D disposal capacity of Segment 1 and Cell 1 of the C&D landfill is <br /> depleted, an event scheduled to occur in 2010, further C&D debris disposal will be in a <br /> Class I landfill commingled with MSW. <br /> The principal drawback to the codisposal approach is the high capital and operating <br /> costs of the Class I landfill in comparison with those of a C&D landfill . These, <br /> however, would be offset by the savings that would result from the discontinued <br /> operation of the separate C&D landfill, and from several construction steps that would <br /> not be necessary due to the integration of the C&D Cell 2 into Segment 3 of the Class I <br /> landfill . These are further discussed in subsequent sections of this report. <br /> JR70184 3 7/ 13/2007 <br />
