The LFG <br /> system capacity is terms of the total LFG quantity including methane, carbon dioxide, and <br /> other gases. <br /> TABLE 2 <br /> CALCULATED LFG SYSTEM CAPACITY REQUIREMENTS <br /> REQUIRED REQUIRED REQUIRED <br /> YEAR AT LFG SYSTEM LFG SYSTEM LFG SYSTEM <br /> LANDFILL END OF CAPACITY (CFM) CAPACITY (CFM) CAPACITY(CFM) <br /> PHASE PHASE @ 500 j2pm @ 1,000 ppm @ 4,000 j22m <br /> PHASE I 2007 94 94 447 <br /> PHASE II 2012 355 355 925 <br /> PHASE III 2018 433 719 1,426 <br /> PHASE IV 2030 1,195 1,571 2,283 <br /> PHASE V 2038 1,745 2,099 2,807 <br /> PHASE VI 2053 2,300 3,089 3,811 <br /> The most likely LFG system capacity requirement for the Austin Road Landfill Expansion is <br /> in the range of the 500 to 1,000 ppm NMOC concentration calculations. Based on this, the <br /> maximum system capacity requirements are expected to be in the range of 400 to 800 CFM <br /> by the end of Phase III and in the range of 2,000 to 3,100 CFM by the end of Phase VI (final <br /> closure of the landfill faculty). <br /> WW-1811-CA1-AA/3110 Austin Road Landfill Expansion August 3, 1995 <br /> MU037.DOC Landfill Gas Generation and Emissions Page 6 <br />
