Earlier this week, EPA published its proposed new methane regulations for the oil and gas sector. These new rules will have significant practical implications for the industry and have the potential to set new precedent for EPA’s authority under the Clean Air Act to address climate change for other industries as well. While the proposal is over 150 pages long, it does not include the actual text of the proposed rules, promising instead to provide proposed text in a supplemental notice early next year.

The U.S. Supreme Court has elected to hear a legal dispute over the scope of the authority granted to the Environmental Protection Agency (EPA) under the Clean Air Act to regulate greenhouse gas (GHG) emissions from existing power plants. In orders issued October 29, the Court granted certiorari to four petitioners — West Virginia, North Dakota, the North American Coal Corporation, and Westmoreland Mining Holdings LLC — seeking reversal of a September 2020 D.C. Circuit Court of Appeals decision striking down the Affordable Clean Energy (ACE) rule.

The Biden EPA just did something unexpected — it decided to keep a Trump EPA rule, at least for the time being. The rule, known as “project emissions accounting” under the “New Source Review” (NSR) air permitting program, allows sources of air emissions to avoid permitting by using emission decreases to offset an increase that would otherwise need a permit. While largely procedural in nature, EPA’s decision to keep the rule is notable for a few reasons.

At the end of September, the Environmental Protection Agency (EPA) issued yet another memorandum regarding emissions resulting from startup, shutdown, and malfunctions (SSM) at stationary sources of air pollutants, such as refineries, manufacturing facilities, and power plants. This newest memo announces a return to the policy EPA announced in 2015, when it asked 45 states and local jurisdictions to change their locally written and previously EPA-approved rules. EPA’s goal in 2015 was to eliminate state rules that allow relief from penalties for “SSM” emissions. In 2020, the Trump EPA issued a memo allowing such rules under certain circumstances, but the newest EPA memo puts those rules back on the chopping block. This post provides a brief recap of the long-running debate over SSM emissions and a look forward into what is to come under EPA’s latest policy shift.

The Virginia Code requires a site suitability determination for all projects seeking air emission permits. Va. Code 10.1-1307.E. While this provision has been in place for decades, it has never received significant attention, and has historically been interpreted to require compliance with local zoning laws. In 2020, however, environmental groups used the law to successfully challenge a minor new source permit for a compressor station associated with an interstate natural gas pipeline. They argued that the site suitability analysis undertaken by the Virginia Department of Environmental Quality (DEQ) did not adequately address or consider environmental justice concerns, and the Fourth Circuit Court of Appeals agreed. Friends of Buckingham v. State Air Pollution Control Bd., 947 F. 3d 68 (4th Cir. 2020).

The Congressional Review Act (CRA) was adopted in 1996 to give Congress a more powerful check on agency regulation that outpaces congressional intent. But now, for the first time, Congress has used that powerful authority in reverse. By disapproving a de-regulatory action — the rescission of the Subpart OOOOa new source methane standards for the oil and gas sector — Congress has brought a dead rule back to life. The birth, death, and now re-birth of Subpart OOOOa (often pronounced “quad-O-A”) raises several new and important questions.

Although the Biden administration has yet to issue many new substantive air quality regulations, Biden’s EPA recently issued two rules revoking Trump-era procedural regulations that should pave the way for a more aggressive regulatory agenda. On May 13, EPA rescinded the “Increasing Consistency and Transparency in Considering Benefits and Costs in the Clean Air Act Rulemaking Process Rule” (Cost-Benefit Rule), a requirement governing cost-benefit analyses for Clean Air Act (CAA) rulemakings, and on May 18, the agency revoked the “EPA Guidance; Administrative Procedures for Issuance and Public Petitions Rule” (Guidance Document Rule), which required all “significant” EPA guidance to undergo a public notice and comment process prior to issuance, modification, or withdrawal.
