Mr.Robert McClellon <br /> Gas Extraction Well Permit for Forward Landfill <br /> August 6,2008 <br /> Page 2 of 2 <br /> 2. Provide calculations regarding capacity of system to handle the addition of the <br /> extraction wells. <br /> In 2007, the flare station was expanded to handle future addition/gas flow from the <br /> landfill. Flare#1 has 2,000 SCFM of capacity and Flare#2 has 3,500 SCFM of capacity. <br /> The flare station is currently only processing approximately 1,410 SCFM of landfill gas. <br /> Thus, the flare station has the capability to process much more landfill gas as the site <br /> continues to expand. <br /> The site has approximately 243 vertical gas extraction installed in waste, 46 soil vapor <br /> extraction wells, and several horizontal gas collectors. Thus, on average, each well is <br /> producing between 5 and 6 SCFM of landfill gas. The impact these additional wells will <br /> have on overall system is minimal. <br /> 1 <br /> 3.
