r.� <br />Ameresco San Joaquin LLC GHG Analysis <br />April 12, 2011 <br />Using California Air Resources Board Mandatory GHG Emission program, the Green <br />House Gas emissions in CO2e from the four point sources at the Foothill Landfill are: <br />1. Ameresco Engines, 2 Jenbacher 616 18 bar engines: <br />2 Engines = 39.6 MMBtu/hr * 116.376 = 4608 lbs./hr. of CO2e biogenic <br />emissions <br />2. - Ameresco VOC Flare: <br />VOC Flare = 6.6 MMBtu/hr * 116.376 = 768 lbs./hr. of CO2e biogenic emissions <br />3. County Candlestick Flare: <br />PSVSWA Flare = 60.7 MMBtu/hr.*116.376 = 7064 lb./hr. of CO2e biogenic <br />emissions <br />Flare data from Foothill Landfill Air Permit <br />As is shown above, when Ameresco's LFGTE facility begins operating there will be a <br />decrease of CO2e emissions from the site as the County flare is permitted for more gas <br />flow than the LFGTE Facility. In addition, when the electrical power generated by the <br />LFGTE facility is considered to offset fossil fueled power generation, which would <br />otherwise generate 13,888 metric tons/year CO2e, the Ameresco plant results in an <br />overall decrease of CO2e equivalent GHG emissions(1). <br />(1) Displaced Fossil Fuel Utility Emissions factor from CAMX eGrid 2005. <br />
