⚖ Oral Arguments, with Context

The D.C. Circuit hears a challenge to EPA's delay of air-pollution requirements for oil and gas facilities. In 2024, EPA adopted rules to reduce methane and other emissions from new, modified, and existing facilities. The requirements cover pollution-control equipment, leaking valves and storage tanks, and a program to identify and respond to unusually large methane releases. Existing facilities are addressed through plans developed by states under EPA's guidelines. In July 2025, EPA extended many compliance dates and the state-plan deadline to January twenty-second, twenty twenty-seven. After public comments, a December 2025 final rule affirmed those extensions and also pushed back initial annual reporting. Environmental Defense Fund and other environmental organizations petitioned this court to set aside that final rule. They say EPA ignored the health and climate consequences of delay and relied on unsupported industry assertions. EPA maintains that it considered emissions and reasonably extended deadlines that were not workable because of equipment shortages and technical problems. The judges will examine the justification for individual extensions and whether EPA adequately considered the pollution consequences. They will also ask whether the groups have shown injuries to their members that let them challenge each extension. Grace Smith, an Environmental Defense Fund attorney, will argue for the groups.
