Based on the above criteria and utilizing a inflow rate of 33,150 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 10 years (as of December 31, 2007). Based on these <br /> calculations (see Table 8), operations at the Forward Landfill could extend to <br /> February 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 <br /> and the annual tonnage delivered to the landfill. The actual daily tonnage at <br /> the Forward Landfill depends on economic and population growth factors. <br /> The tonnage can also vary as the contracts with clients fluctuate and <br /> specialty markets change. Therefore, there may be times when the Forward <br /> Landfill will accept at or near the maximum permitted tonnage or times where <br /> it may fall way below. Table 8 is presented to provide an estimate of the <br /> inflow to the Forward Landfill for permitting purposes. <br /> In addition, long-term landfill settlement can also have a great impact on site <br /> capacity and may average 25 percent of the total refuse thickness. The total <br /> effects of settlement will depend on various factors or processes such as the <br /> types of refuse placed and their corresponding moisture content, the refuse <br /> placement density, consolidation of the refuse under loads imposed by <br /> overlying fill, and biological and chemical decomposition. It is estimated that <br /> much of this total settlement will occur during the operating life of the landfill <br /> and will be accounted for in periodic topographic surveys. <br /> Remaining site capacity will be evaluated periodically and any significant <br /> changes will be addressed during future operating permit revisions. <br /> Forward Landfill JTD 4-12 <br /> Z:\PROJECTSWfied WasteWN81013 5 yr Review Plan\JTD Amend\JTD Sec 4.doc: <br /> 05/24/02;Amendment No. 1: 2/1/2007;Amendment No.2: 5/15/2008 <br />
