On July 31, 2025, EPA published in the Federal Register its highly anticipated Interim Final Rule to extend several deadlines in 40 C.F.R. Part 60, Subparts OOOO, OOOOa, OOOOb and OOOOc that were promulgated in EPA’s 2024 Methane Rule. 90 Fed. Reg. 35966 (July 31, 2025). That same day, environmental groups filed a lawsuit challenging the Interim Final Rule. Envtl. Defense Fund v. U.S. EPA, Case #25-1164 (D.C. Cir.). Absent a stay by the court, which the environmental groups are currently not seeking, the Interim Final Rule and the various extended deadlines are effective.
Summary of Deadline Extensions
The Interim Final Rule extends numerous compliance deadlines for oil and gas air emission sources subject to the New Source Performance Standards in 40 C.F.R. Part 60 Subparts OOOO, OOOOa, OOOOb and OOOOc. The previous compliance deadlines were published in a March 2024 final rule. 89 Fed. Reg. 16820 (March 8, 2024). The Interim Final Rule, which became effective upon publication, extends many deadlines in OOOOb, the date that the requirements of the Super-Emitter Program apply with respect to OOOO, OOOOa, and OOOOb, and the date by which states must submit plans to EPA pursuant to the OOOOc emissions guidelines.
EPA extended the following OOOOb compliance deadlines to at least January 22, 2027:
