U.S. EPA Announces New “Strategic Civil-Criminal Enforcement Policy”
On April 17, 2024, the U.S. Environmental Protection Agency (EPA) published its “Strategic Civil-Criminal Enforcement Policy,” a landmark new internal enforcement policy for its civil and criminal enforcement offices (the Policy) that signals a paradigm shift in how the agency will assess, coordinate, and prosecute civil (including administrative) and criminal environmental enforcement. In the Policy, EPA states that it has already started increasing communication and collaboration between its enforcement offices in recent years, which EPA believes has led to better case screening and more consistent enforcement responses across regions. But the Policy goes far beyond those less formal efforts and reflects EPA’s stated goal to continue toward an integrated approach, moving away from its prior, more bifurcated approach to civil and criminal enforcement.
U.S. EPA Announces New National Primary Drinking Water Regulations for PFAS
On April 10, 2024, the U.S. Environmental Protection Agency (EPA) announced the first-ever legally enforceable drinking water standards for per- and polyfluoroalkyl substances (PFAS). PFAS are a group of thousands of manmade chemicals that have been manufactured and used globally since the 1940s. They are commonly found in textiles, cookware, packaging, plastics, and firefighting foams. PFAS are typically very persistent in the environment and in the human body, meaning that they do not break down and can accumulate over long periods of time. For that reason, they are often called “forever chemicals.” This action is the most recent step in the EPA’s October 2021 “PFAS Strategic Roadmap,” a report establishing action items to address PFAS contamination and timelines for their completion.
The Newest Phase of EPA’s Greenhouse Gas Emissions Standards: Phase 3
On March 29, 2024, the U.S. Environmental Protection Agency (EPA) announced its most recent national greenhouse gas (GHG) pollution standards for heavy-duty (HD) vehicles, including HD vocational vehicles and tractors. The rule establishes new CO2 emission standards for model year (MY) 2032 and later HD vehicles, with more stringent CO2 standards phasing in as early as MY 2027 for certain vehicle categories.
Fifth Circuit Limits EPA’s Attempts to Regulate PFAS Under Toxic Substances Control Act in Inhance Technologies v. EPA
On March 21, 2024, the U.S. Court of Appeals for the Fifth Circuit vacated two U.S. Environmental Protection Agency (EPA) orders under Section 5 of the Toxic Substances Control Act (TSCA), holding that EPA had exceeded its statutory authority when it issued the orders in an attempt to regulate the manufacture of per- and polyfluorinated substances (PFAS) by petitioner Inhance Technologies, LLC (Inhance). The Fifth Circuit’s decision comes after EPA’s Office of Enforcement and Compliance Assurance announced its National Enforcement and Compliance Initiatives for Fiscal Years 2024 – 2027, which involve increased emphasis on addressing PFAS exposure and contamination through enforcement actions and potential additional regulations.
U.S. Environmental Protection Agency Releases Draft Risk Evaluation Under the Toxic Substances Control Act for Formaldehyde
On March 15, 2024, the U.S. Environmental Protection Agency (EPA or the Agency) published its draft risk evaluation under the Toxic Substances Control Act (TSCA) for formaldehyde. This proposal is one of a series of risk evaluations EPA is conducting as required by the 2016 amendments to TSCA.
U.S. EPA Sets Stricter National Ambient Air Quality Standards for Particulate Matter
On February 7, 2024, the U.S. Environmental Protection Agency (EPA) issued a final rule under the Clean Air Act lowering the primary (health-based) annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter 2.5 micrometers in diameter or smaller (PM2.5) from 12 to 9 micrograms per cubic meter (µg/m3). EPA asserts that the stricter standard is based on scientific evidence showing that the current PM2.5 standard (12 µg/m3), which was established in 2012 and retained in 2020, does not sufficiently protect human health. According to EPA, based on air monitoring data from 2020-22, 119 counties would not meet the new standard of 9 µg/m3.

U.S. EPA Issues Draft Final Oil and Gas Methane Rule
The U.S. Environmental Protection Agency (EPA) released a draft of its final oil and gas methane rule on December 2, 2023. It may be some time before the final rule is officially published in the Federal Register, starting the clock on the rule’s compliance obligations. Interested parties will need that extra time to fully digest the 1,690-page draft final rule, which addresses methane emissions from new (in subpart OOOOb) and existing sources (in subpart OOOOc). Here are some of the rule’s key aspects to consider. (more…)
U.S. Fifth Circuit Reverses EPA’s Denial of Fuel Program Hardship Exemption for Refineries
In Calumet Shreveport Refining LLC v. EPA, Case No. 22-60266 (5th Cir. Nov. 22, 2023), the U.S. Court of Appeals for the Fifth Circuit struck down Environmental Protection Agency (EPA) denials of six small refineries’ petitions for hardship relief under the Clean Air Act Renewable Fuel Standard (RFS) program, holding that EPA used an “impermissibly retroactive” standard to deny the refineries’ petitions in violation of the Administrative Procedure Act. This ruling could serve as a basis for other refineries to challenge EPA’s retroactive denial of their hardship petitions — and provides support for similar petitions pending before the U.S. Court of Appeals for the D.C. Circuit.
U.S. EPA Publishes New Regulations Governing State Plans for Existing Sources of Emissions
On November 9, 2023, the U.S. Environmental Protection Agency (EPA) published implementing regulations that set timelines and other requirements for state plans to limit pollution from existing sources under Clean Air Act (CAA) Section 111. The amended provisions apply to all emissions guidelines published after July 8, 2019, and will affect the scope and pace of development of updated performance standards for existing facilities.
