(i.e., low) in-place density because the volume of fill placed is not reduced to <br /> account for cover soil. The tons of refuse are divided into the total volume of <br /> airspace filled, which includes cover soils. If the volume of cover soils were <br /> subtracted from the volume of fill placed, the calculated in-place density of refuse <br /> would increase (i.e., the same number of tons were placed in fewer cubic yards of <br /> airspace), which would result in a longer estimated site life. The site capacity <br /> calculations reflecting this information are included in Appendix C. <br /> 4.7 SITE LIFE PROJECTION <br /> 4.7.1 SITE LIFE CALCULATIONS <br /> In order to calculate the site life for the Forward Landfill, the following criteria <br /> was utilized. <br /> • Remaining Site Capacity (with liner, daily, <br /> intermediate and final cover) 3&83 ,29.38 mcy <br /> • Refuse to Cover Ratio 4:1 <br /> • In-Place Density 1,740 lbs/cy <br /> Based on the above criteria and utilizing a inflow rate of 32,506 tons/week with <br /> a 2 percent annual growth rate and a maximum weekly permitted refuse inflow <br /> rate of 46,080 tons/week, the Forward Landfill will have a projected site life of <br /> approximately_11 years (as of Januap�-May 2006). Based on these calculations <br /> (see Table 8), operations at the Forward Landfill could extend to April 2017. <br /> 4.7.2 FACTORS AFFECTING SITE CAPACITY <br /> Many factors can affect the ultimate site capacity of a given landfill including <br /> variations in waste type, compaction rates, the use of alternative daily covers and <br /> the annual tonnage delivered to the landfill. The actual daily tonnage at the <br /> Forward Landfill depends greatly on the economy. Sinee a geed Majeriley, A <br /> portion of the waste accepted at the Forward Landfill will-be-is <br /> construction/demolition type wastes., the infleky will be The actual amount of <br /> C&D waste is dependent on how much of that type of work is occurring in the <br /> area. The tonnage will also vary as the contracts with clients fluctuate and <br /> specialty markets change.
