EPA finalizes landfill emissions rules

Combined, the final rules are expected to reduce methane emissions by an estimated 334,000 tons a year beginning in 2025—equivalent to reducing 8.2 million metric tons of carbon dioxide. EPA estimates the climate benefits of the combined rules at $512 million in 2025 or more than $8 for every dollar spent to comply.

 

Municipal solid waste (MSW) landfills receive non-hazardous waste from homes, businesses and institutions. As landfill waste decomposes, it produces a number of pollutants, including air toxics, volatile organic compounds, carbon dioxide and methane. MSW landfills are the second-largest industrial source of methane emissions in the United States, accounting for 20 percent of methane emissions in 2014. Methane from landfills can be cost-effectively captured and used in place of other fossil fuels.
 

The final rules took into account public comments and additional data and analysis received since the agency issued the proposals in July 2014 and August 2015. The actions update the 1996 guidelines for existing landfills and strengthen the previously proposed rule for new landfills issued in 2014.

 

In addition, EPA’s Landfill Methane Outreach Program (LMOP) provides landfill owners and operators a suite of tools and technical resources to facilitate development of landfill gas energy projects. Over the last 20 years, LMOP-assisted projects have reduced and avoided more than 345 million metric tons of carbon dioxide equivalent.

 

These actions are another step toward implementing President Obama’s Climate Action Plan: Strategy to Reduce Methane Emissions. They come after EPA’s release of standards for new and modified oil and gas sources this spring.
