EPA confirms oil, gas emissions compliance extensions
The Environmental Protection Agency (EPA) issued a rule on December 3, 2025, that finalizes compliance deadline extensions for certain emissions standards applicable to crude oil and natural gas facilities. The final rule also further delays compliance timelines for two requirements.
EPA’s delays affect:
- The New Source Performance Standards for crude oil and natural gas facilities (40 CFR 60 Subpart OOOOb), and
- The emissions guidelines (EGs) for crude oil and natural gas facilities (60 Subpart OOOOc).
EPA’s December 2025 final rule is a direct response to the interim final rule (IFR) it issued in July 2025.
The July 2025 IFR extended the compliance deadline for net heating value (NHV) monitoring of flares and enclosed combustion devices (ECDs) to November 28, 2025. The IFR moved the rest of the compliance deadlines to January 22, 2027, for:
- ECD performance tests;
- Cover and closed vent system requirements for no identifiable emissions (NIEs), including:
- Design and operation standards,
- Test methods and procedures, and
- Inspections.
- Equipment leak repair requirements;
- Phase two of zero-emission standards for process controllers;
- Storage vessel requirements, including:
- Using potential emissions limits that qualify as legally and practicably enforceable,
- Triggering throughput-based modifications, and
- Using a 30-day period of production to calculate potential emissions.
- Flare and ECD pilot flame rules, including:
- Ensuring the devices operate with a continuous pilot flame, and
- Installing and operating a system to send an alarm to the nearest control room when a pilot flame is unlit.
- Implementation of the Super Emitter Program, and
- Submission of state plans for implementing the updated EGs.
What’s the same?
EPA’s December 2025 final rule maintains the same compliance deadlines for all requirements delayed to January 22, 2027.
What’s different?
The agency’s December 2025 final rule sets a new compliance date of June 1, 2026, for the NHV monitoring requirements. This includes an alternative performance test (sampling demonstration) option for flares and ECDs.
Additionally, the rule moves the compliance date for annual reporting, establishing that no annual report is due before November 30, 2026. It gives owners and operators until November 30, 2026, to submit any reports that were originally due before this date. Note that the final rule specifies that annual reports due after November 30, 2026, must be submitted within 90 days of the end of each annual compliance period.
Key to remember: EPA’s final rule confirms deadline extensions for certain emissions standards that apply to crude oil and natural gas facilities. It also further delays a couple of the requirements.
