Proposed rule - The U.S. Environmental Protection Agency (EPA) is proposing amendments to the New Source Performance Standards and Emission Guidelines for the Crude Oil and Natural Gas Source Category to address additional concerns raised with prior regulatory amendments finalized in March 2024. Specifically, the EPA is proposing changes in response to certain petitions for reconsideration of the March 2024 amendments, changes based on policy decisions and supporting legal interpretations, and changes that correct and clarify the regulatory text of the new source performance standards and emission guidelines. First, the EPA proposes to rescind the Super Emitter Program. Second, the EPA proposes to subcategorize different types of well sites affected and designated facilities to address issues related to the requirements finalized in March 2024 for marginal well sites and conventional well sites. Third, the EPA proposes changes to address issues related to liquids unloading, process controllers, pumps, fugitive emissions, storage vessels, covers and closed vent systems, equipment leaks at gas plants, and associated gas. Fourth, the EPA proposes changes to certain requirements finalized in March 2024 related to control devices and to provide owners and operators the option to conduct optical gas imaging surveys according to Appendix K for gas processing facilities. Lastly, the EPA proposes changes to correct inadvertent errors and to clarify regulatory language. EPA will hold…

Reconsideration of Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
Final rule - The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the New Source Performance Standards (NSPS) and Emission Guidelines (EG) for Existing Sources for the Crude Oil and Natural Gas Source Category in response to petitions for reconsideration of the 8 March 2024 final rule (notified in G/TBT/N/USA/1804/Add.3). Specifically, this action finalizes discrete technical changes to two aspects of the rules. First, this action finalizes discrete technical changes to the temporary flaring provisions for associated gas in certain situations. Second, this action finalizes discrete technical changes to the vent gas net heating value (NHV) continuous monitoring requirements and alternative performance test (sampling demonstration) option for flares and enclosed combustion device(s) (ECD). In a letter dated 6 May 2024, the EPA notified petitioners and the public that the Agency granted reconsideration on these two aspects of the final rule. These amendments neither finalize changes to any other aspect of the 8 March 2024, final rule, nor finalize alterations to the substance of any emission standards within that final rule. This action also finalizes a technical correction to reinstate regulatory text for the reporting requirements in 40 CFR 60.5420b(b)(1) through (15), which were mistakenly deleted by the December 2025 Final Rule (notified in G/TBT/N/USA/1802/Rev.1/Add.3).

Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
Proposed rule - This document comprises three distinct groups of actions under the Clean Air Act (CAA) which are collectively intended to significantly reduce emissions of greenhouse gases (GHGs) and other harmful air pollutants from the Crude Oil and Natural Gas source category. First, the EPA proposes to revise the new source performance standards (NSPS) for GHGs and volatile organic compounds (VOCs) for the Crude Oil and Natural Gas source category under the CAA to reflect the Agency's most recent review of the feasibility and cost of reducing emissions from these sources. Second, the EPA proposes emissions guidelines (EG) under the CAA, for states to follow in developing, submitting, and implementing state plans to establish performance standards to limit GHGs from existing sources (designated facilities) in the Crude Oil and Natural Gas source category. Third, the EPA is taking several related actions stemming from the joint resolution of Congress, adopted on 30 June 2021 under the Congressional Review Act (CRA), disapproving the EPA's final rule titled, 'Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources Review,' 14 September 2020 ('2020 Policy Rule'). This proposal responds to the President's 20 January 2021, Executive order (E.O.) titled 'Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis,' which directed the EPA to consider taking the actions proposed here.
