EPA’s standards for hazardous air pollutant (HAP) emissions from industrial boilers have been controversial for nearly two decades. Ever since EPA first proposed “maximum achievable control technology” (MACT) standards for boilers in 2003, which were then entirely vacated by the D.C. Circuit, each new iteration of the rule has raised new legal issues and often foundered in court.

On the last day of what was already an historic term, the Supreme Court issued another significant decision impacting EPA’s authority under the Clean Air Act to regulate greenhouse gas emissions and address climate change. As EPA embarks on a third attempt at a rule targeting CO2 emissions from existing power plants that will pass legal muster, the question now is how the Court’s decision will affect that new rule.

In a proposed rule signed on February 28, but not yet published in the Federal Register, EPA proposed to significantly expand its current approach to regulating the interstate transport of ozone. Under the so-called “good neighbor” provision of the Clean Air Act, states are required to submit State Implementation Plans (SIPs) to EPA containing rules sufficient to prohibit emissions from their state that would either significantly contribute to another state’s nonattainment of national ambient air quality standards or interfere with another state’s maintenance of those standards. If a state submits a SIP that is insufficient to satisfy its good neighbor obligation, EPA must issue a Federal Implementation Plan (FIP) to fully address the problem.

As the U.S. Environmental Protection Agency (EPA) prepares its Clean Water Act (CWA) Section 401 rule proposal, litigation regarding the 2020 Trump-era rule (Certification Rule) continues. Currently, the issue of whether to re-instate the Certification Rule is proceeding before U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit). The U.S. District Court for the Northern District of California had vacated and remanded the Certification Rule, and intervenors and several states appealed the vacatur. Appellants, including several industry groups, have filed motions to stay the District Court’s vacatur pending the outcome of the appeal and are now awaiting the Ninth Circuit’s ruling that could, at least temporarily, re-instate the Certification Rule.

Dave Ross talks with Radhika Fox as she marks her one year anniversary as EPA’s Assistant Administrator for Water. They discuss how her prior experiences prepared her for the role at EPA and her desire to change the narrative around water by connecting it back to the community. They also look at her first year accomplishments, the recently passed infrastructure bill, the 50th anniversary of the Clean Water Act, and more.

The Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (the “Corps”) (together the “Agencies”) have continued working on a proposed rule to revise the definition of “waters of the United States” (WOTUS) under the Clean Water Act (CWA or Act), which will soon move to the next stage of agency consideration.[1] The outcome of these rulemaking efforts will impact countless regulated parties, from solar developers to manufacturers, and heavily regulated industry.

On January 11, the U.S. Environmental Protection Agency (EPA) issued a new interpretation of its coal combustion residual (CCR) regulations: CCR landfills or surface impoundments “cannot be closed with coal ash in contact with groundwater.” Although EPA claims it has “consistently held” this interpretation, this is the first time EPA has expressly articulated this view. Perhaps acknowledging the novelty of its position, EPA also announced its intent to “review … state-level CCR program applications to ensure they are as protective as federal regulations” and to proceed toward a federal CCR permitting framework.

Gearing up for a potential final rule in summer 2023, the U.S. Environmental Protection Agency (EPA) on January 10 submitted a proposed rule to the White House Office of Management and Budget (OMB) to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). OMB reviews are generally targeted to be completed within 90 days, but they can last much longer — or be concluded more quickly — depending on the rule being studied. The submittal is consistent with what EPA forecasted in its October 2021 PFAS Roadmap and its Unified Agenda.

On October 21, the U.S. District Court for the Northern District of California vacated and remanded the U.S. Environmental Protection Agency’s (EPA) 2020 Clean Water Act Section 401 final rule (Certification Rule).

In response to the court’s ruling, EPA is implementing the previous water quality certification rule nationwide, which had been in effect since 1971, while it develops a new rule.

Pursuant to Section 401 of the Clean Water Act (CWA), no federal license or permit that may result in a discharge to U.S. waters may be issued unless the state or authorized Tribe, where the discharge will originate, issues a water quality certification or waives the certification requirement.
