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.

Landowners and permit applicants received an email notification this week that the Army Corps of Engineers (Army Corps) would not be processing their requests for coverage under a variety of Clean Water Act (CWA) Section 404 Nationwide Permits (NWPs). NWPs are general permits that authorize activities under Clean Water Act Section 404 that “will cause only minimal adverse environmental effects when performed separately, and will have only minimal cumulative adverse effects on the environment.” CWA Section 404 (e)(1).

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.

Today, the U.S. Environmental Protection Agency (EPA) announced a new “Strategic Roadmap (Roadmap),” describing a suite of ongoing and future agency actions to address per- and polyfluoroalkyl substances (PFAS). While many of these actions were previously presented in EPA’s 2019 PFAS Action Plan, or in more recent announcements, the Roadmap provides additional updates and clarity into the expected timing of some regulatory actions. The new projected dates for some key regulatory initiatives include the following:

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.

A recent decision by the U.S. District Court for the District of Arizona vacated and remanded the 2020 Navigable Waters Protection Rule (NWPR) issued by the Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (Corps) (together, “Agencies”) that clarified the scope of federal jurisdictional “Waters of the United States” (WOTUS) under the Clean Water Act (CWA). Before the promulgation of the NWPR, there had been several rulemakings and much litigation on this complicated issue, causing nationwide confusion on the application of a uniform standard. In 2015, the Obama administration promulgated a WOTUS rule that had been the subject of significant litigation, which the Trump administration had repealed (the “Repeal Rule”). The NWPR sought to provide certainty as to which waterbodies meet the features of WOTUS by creating clear categories of jurisdictional waterbodies.

The Environmental Protection Agency (EPA) has initiated two rulemaking actions, both expected to be proposed in early 2022, that could change the way the Clean Water Act (CWA) is administered across the country. Together, these actions would elevate tribal rights in water quality regulatory decision-making and could provide EPA with significantly greater authority to regulate discharges on and upstream of tribal lands.

On August 19, EPA and the Army Corps of Engineers (Corps) issued a joint guidance document concerning implementation of EPA’s 2020 Water Quality Certification Rule. The agencies explain that the guidance applies specifically to 41 Clean Water Act Section 404 Nationwide Permits (NWPs) proposed in September 2020 that have already received certification (or for which certification was denied or waived) but have not yet been finalized, and a more detailed enclosure is intended to be applied generally to the Corps’ permit programs. The guidance also cryptically suggests that the agencies may revisit the 16 NWPs that were previously certified and finalized by the Corps in January 2021. In a press release the following day, EPA and the Corps frame the guidance as addressing “implementation challenges” raised by state and tribal certifying authorities.
