Energy Alert
(by Gary Steinbauer and Christina Puhnaty)
On December 2, 2023, the U.S. Environmental Protection Agency (EPA) released a pre-publication version of its final 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 Final Rule comes more than two years after EPA published its initial proposal on November 15, 2021 (Initial Proposal) and a supplemental proposal on December 6, 2022 (Supplemental Proposal) (collectively, the “Proposals”). According to EPA, the agency received over one million comments on the Proposals. For information on the Proposals, please see our November 11, 2021 and December 12, 2022 Alerts. This Alert focuses on critical aspects of the Final Rule, including key changes that EPA made since issuing the Proposals.[1]
Brief Overview of Methane Rule
The Methane Rule is comprised of four separate actions proposed under sections 111(b) and 111(d) of the Clean Air Act. EPA currently regulates emissions of volatile organic compounds (VOCs) and methane from oil and natural gas facilities under 40 C.F.R. Part 60 Subparts OOOO[2] and OOOOa.[3] First, through this Final Rule, EPA will regulate oil and natural gas facilities constructed, modified, or reconstructed after December 6, 2022, under a new Subpart OOOOb. The requirements in OOOOb will apply to affected facilities 60 days after the rule is published in the Federal Register. Second, under a new Subpart OOOOc, EPA finalized emissions guidelines that are intended to inform states in the development, submittal, and implementation of state plans to establish standards of performance for greenhouse gases (in the form of limitations on methane) from sources existing on or before December 6, 2022. …
