The EPA Office of Superfund Remediation and Technology Innovation conducted a study in 2010 to explore options for productively utilizing methane emissions from landfills that are placed on the Superfund National Priorities List. The study included the development of the Landfill Gas Energy Project Assessment Tool, which can be used to aid managers in conducting their own assessment of the feasibility of installing landfill gas energy projects at landfills. The scope of the Tool will be presented, together with a discussion of the Fresno Sanitary Landfill in California as a comparison case study by applying the EPA LandGEM and LFGCost models.
Both LandGEM and LFGCost are routinely used by the EPA Landfill Methane Outreach Program. Total landfill gas and methane generation for the Fresno Sanitary Landfill were estimated using LandGEM version 3.02, released May 12, 2005, which is an automated tool for estimating emission rates from municipal solid waste (MSW) landfills. The model was developed by the EPA Office of Research and Development-National Risk Management Research Laboratory, and the Clean Air Technology Center. The model results can be used to estimate the recoverable methane available for a potential LFG energy project. LandGEM can also be used by landfill owners and operators to determine if a landfill is subject to the control requirements of the federal New Source Performance Standard (NSPS) for new MSW landfills, the emission guidelines for existing MSW landfills, or the National Emission Standards for Hazardous Air Pollutants (NESHAP) for MSW landfills. In evaluating the economic feasibility of an LFG energy project at the Fresno Sanitary Landfill, EPA’s LFGcost Tool was utilized. This webinar will review the assumptions made in the Tool and the resulting economic outlook for a potential project at this site.
