The EPA is gearing up to introduce a new rule in 2025 aimed at reducing methane emissions from landfills, which are a significant source of greenhouse gases in the United States. Landfills account for more than 17 percent of human-caused methane pollution, making them a key target for climate change mitigation efforts.
Methane, a potent greenhouse gas, has 80 times the heat-trapping capability of carbon dioxide over a 20-year period. Landfill gas, which is a combination of methane, carbon dioxide, and other pollutants, can contribute to ozone pollution, particle pollution, and unpleasant odors in communities near waste facilities.
Experts believe that implementing emissions controls for landfills could lead to substantial reductions in methane emissions at a low cost. In fact, some studies suggest that controlling methane emissions from landfills may cost just a few dollars per ton, making it a cost-effective solution compared to other sectors.
The EPA is currently reviewing its 2016 standards for landfill emissions and is expected to propose a draft rule in 2025 for both new and existing landfills. The agency is also exploring new technologies and approaches that could help reduce harmful air pollution and improve emissions monitoring in frontline communities.
While environmental groups have been pushing for stronger regulations on landfill emissions, industry representatives are concerned about the timeline for state approval of emissions control systems. They are looking for regulatory certainty and flexibility in the upcoming rule to ensure compliance across different types of landfills.
Advancements in methane monitoring technology have made it easier to identify and fix leaks in landfill gas systems. These technological advances could play a crucial role in improving emissions management and reducing the environmental impact of landfills.
Overall, the upcoming EPA rule on landfill emissions is seen as a critical step in addressing climate change and reducing methane pollution. By implementing effective emissions controls and monitoring systems, the U.S. can make significant progress in mitigating the impact of landfills on the environment and public health.
