EPA Extends Compliance Deadlines for Oil and Gas Methane Rules

The U.S. Environmental Protection Agency (EPA) has issued an interim final rule extending several compliance deadlines under the 2024 New Source Performance Standards (NSPS) and Emissions Guidelines for oil and natural gas operations, also known as OOOOb/c. The decision, announced on July 28, 2025, provides operators and states more time to meet requirements designed to limit methane and volatile organic compound (VOC) emissions across the energy sector.

Key Compliance Extensions

• New and Modified Sources: Owners and operators of covered oil and gas sites now have 18 additional months after publication to meet requirements related to equipment leaks, control devices, storage vessels, and closed vent systems. This includes extended deadlines for flare operations and alarm systems that monitor continuous pilot flames.
• Monitoring Requirements: For continuous monitoring of the vent gas net heating value – a key indicator of flare performance – the deadline has been extended by 120 days after publication.
• State Plans for Existing Sources: States originally had until March 2026 to submit methane reduction plans for existing oil and gas sources. That deadline has now been pushed 10 months later, giving states roughly 18 months from publication to finalize and submit their plans.
• Super Emitter Program: The program allowing third parties to use EPA-approved remote sensing to identify large methane leaks has been delayed 18 months due to what the agency called “fundamental flaws” in implementation and technology review processes.

Economic and Environmental Impact

According to EPA’s analysis, the rule is projected to:

• Save the industry approximately $750 million in compliance costs between 2028 and 2039, averaging $81 million per year.
• Result in foregone emissions reductions of 3.8 million tons of methane, 960,000 tons of VOCs, and 36,000 tons of toxic air pollutants over that same period.
• Lead to about $170 million worth of natural gas not captured due to extended timelines.

EPA emphasizes that while these reductions are delayed, the majority of emissions cuts from the 2024 rule will still occur, with an estimated 31 million tons of methane reductions expected over 2028–2038.

Looking Ahead

The interim final rule marks the first in a series of EPA actions to ensure oil and gas regulations remain effective but not overly burdensome. Stakeholders are encouraged to provide written comments within 30 days of publication in the Federal Register.

As the regulatory environment evolves, operators will need to balance compliance planning with operational efficiency – and environmental monitoring will remain a crucial part of the equation.
