New Source Performance Standard for Oil and Gas Sector

On June 3, 2016, EPA published a final rule setting NSPS for greenhouse gases (namely methane) and volatile organic compounds, applicable to new, modified, and reconstructed facilities in the oil and gas sector. Affected facilities include well sites, gathering and boosting stations, processing plants, and compressor stations.


The methane emission standards were challenged in North Dakota v. EPA, No. 16-1242 (D.C. Cir. 2016). State and industry petitioners argued that the rule exceeded EPA’s statutory authority, was unconstitutional, and was arbitrary, capricious, an abuse of discretion, and not in accordance with law. On January 4, 2017 the case was consolidated with American Petroleum Institute v. EPA, No. 13-1108 (D.C. Cir. 2013) and Independent Petroleum Association of America, et al. v. EPA, No. 15-1040 (D.C. Cir. 2015). On January 24, 2017 state and industry petitioners filed a motion asking the D.C. Circuit Court of Appeals to delay the briefing schedule to “allow time for new administration personnel to be briefed on the rules, issues, and history of this litigation, and it would allow them to provide meaningful input on the parties’ discussions regarding the briefing schedule and format.”  On April 7, 2017, EPA filed a motion to hold the case in abeyance in light of its review of the rule (discussed below), which the Court granted.  As of March 2021 the case continues to be held in abeyance. 

Deregulatory Action: 

On March 28, 2017, President Trump issued an executive order instructing EPA to review the oil and gas rule and to rescind or rewrite the rule as needed to promote the President’s goals of energy independence and economic growth. EPA immediately submitted a motion to the D.C. Circuit Court of Appeals to hold the case in abeyance pending EPA’s reconsideration of the rule. The court granted EPA’s request on May 18, 2017.

On April 4, 2017, EPA published a notice in the Federal Register announcing that it is reviewing and, if appropriate, will initiate proceedings to suspend, revise or rescind the rule.

On April 18, 2017, EPA sent a letter to fossil fuel companies stating that it intended to reconsider the fugitive emission standards in the NSPS (the companies had petitioned EPA for reconsideration of those standards). On June 5, 2017, EPA issued a federal register notice stating that it is granting reconsideration of additional requirements in the NSPS, specifically the well site pneumatic pumps standards and the requirements for certification by professional engineer. The EPA indicated that it was staying the requirements for three months pending reconsideration. On June 16, 2017, EPA proposed a two-year stay of the NSPS requirements.

On July 3, 2017, the U.S. Court of Appeals for the District of Columbia Circuit vacated the initial three month stay of the rules, holding that the EPA lacked authority under the Clean Air Act to issue the stay. The court issued a mandate, requiring EPA to begin implementing the rules. The mandate was delayed for 14 days on July 13, 2017, “to give EPA time to determine whether to seek panel rehearing, rehearing en banc, or pursue other relief.” The 14 day period ended on July 28, 2017.

On July 31, 2017, a majority of the full court of the U.S. Court of Appeals for the District of Columbia Circuit ordered “the Clerk to issue the mandate . . . forthwith,” requiring EPA to begin implementing the rules.

On November 8, 2017, EPA issued a notice of data availability in support of its proposed two year stay of the NSPS requirements. The notice provides additional information on topics raised in comments on the stay, including challenges associated with implementing the NSPS requirements, and EPA’s authority to stay implementation.

On October 15, 2018, EPA proposed significant changes to the methane leak detection and repair requirements contained within the methane NSPS for oil and gas sources. The two key changes are: (i) reductions in how frequently oil and gas operators would be required to survey for methane leaks, and (ii) an extension of time provided for leak repair. Both changes will ultimately increase gas losses and associated methane emissions.  Learn More>>

On August 29, 2019, EPA proposed revisions to the NSPS that would effectively eliminate controls on methane emissions from new oil and gas sources.  The proposal would rescind the NSPS requirements applicable to sources involved in the transmission and storage of oil and gas, and rescind the methane requirements applicable to sources in the production and processing segments.  In the alternative, EPA proposes to rescind the methane requirements of the NSPS applicable to all oil and natural gas sources, without altering the source category.    

On August 13, 2020, EPA finalized a rule rescinding the NSPS for methane from oil and gas sources, and in a separate rule, EPA finalized various changes to the volatile organic compound standards that limit their effectiveness in controlling pollution. Learn More>>.

On September 14, 2020, a coalition of states challenged the rule in the D.C. Circuit Court of Appeals. The following day, a coalition of environmental groups filed their own challenge. On February 12, 2021 the court granted the government's motion to stay the case pending review of toth new rules.

Reregulatory Action

On April 28, 2021 the Senate passed a resolution to repeal the EPA's NSPS revisions that eliminated methane controls on the oil and gas sector. The resolution was passed under the Congressional Review Act, which allows the House and Senate to nullify any recently finalized federal regulation by a simple majority vote in both chambers (subject to presidential approval).
