Landfill Methane Regulations

Landfill methane regulations focus on managing methane gas emissions produced by decomposing organic waste in landfills. Methane is a potent greenhouse gas with a short atmospheric lifetime, and these regulations typically involve measures to capture and control methane emissions from landfills to mitigate their impact. This may include the installation of landfill gas collection systems, proper landfill design and management practices, and the use of methane as a renewable energy source through processes like landfill gas-to-energy projects. Effective regulation of landfill methane involves strategies such as monitoring, detection, and appropriate disposal or utilization methods to reduce overall methane emissions.

Landfill owners and operators must install gas collection and control equipment, energy recovery devices, and/or treatment and processing systems to reduce their methane emissions. The rule requires quarterly monitoring of the landfill surface, quarterly monitoring of gas collection and control system equipment, and a timeline to ensure any methane leaks are quickly fixed.
