Do you manage a Superfund landfill site? Is it producing methane gas? Have you wondered how to evaluate and responsibly manage the landfill methane gas? During this training we will discuss resources available to project managers to assess methane productivity at Superfund landfills as well as potential ways to use it as a source of energy or flare it, thereby reducing greenhouse gas emissions. EPA has a wealth of knowledge and experience with landfill gas that may have applicability to Superfund sites. This training will provide a brief overview of the tools available to evaluate, use and flare landfill methane gas and how they may apply to Superfund sites.
Keep in mind that Superfund landfills are typically older, closed sites where codisposal of hazardous and municipal waste has occurred. The emissions will be different from a typical municipal landfill. Because of the age and types of waste, the volume of gas is likely less and concentration of hazardous air pollutants is likely higher. Therefore, before proceeding with exploring economics of energy recovery, the amount and characteristics of the landfill gas need to be evaluated. We will discuss how to conduct an evaluation using EPA's Guidance for Evaluating Landfill Gas Emissions From Closed or Abandoned Facilities (EPA-600/R-05/123a). We will also identify options for controlling emissions through either flaring the gas or recovery for its energy potential.
