On December 18, 2024, the U.S. Environmental Protection Agency (EPA) published a final rule modifying regulations governing the new chemicals review process under the Toxic Substances Control Act (TSCA) (Final Rule). As amended by the 2016 Lautenberg Amendments, TSCA Section 5 establishes prior notice requirements before a new chemical can be manufactured or an existing chemical can be used in new ways.[1] The Final Rule updates EPA practices guiding its review of exemptions and safety determinations, as well as a submitter’s request to start manufacturing, and aligns the implementing regulations with the 2016 amendments.

On Thursday, December 26, 2024, New York Governor Kathy Hochul signed into law the second-in-the-nation Climate Change Superfund Act (the “Act”). The Act had first passed the New York legislature in June 2024, shortly after Vermont’s Climate Superfund Act became law. See, Sidley Update.

Earlier this week, two environmental groups sued the California Air Resources Board (“CARB”) for approving amendments (the “Amendments”) to the Low Carbon Fuel Standard (“LCFS”). CARB had voted to amend the LCFS on November 8, 2024, with the intent of lowering the carbon intensity of the fuel mix in California and encouraging the use of low-carbon transportation fuels. For more details on the LCFS Amendment changes, see Sidley’s Alert.

On November 21, 2024, the U.S. Environmental Protection Agency (EPA) published Notice of a newly developed draft framework intended to provide all EPA programs with a shared reference point for determining when and how to analyze or consider cumulative impacts—defined broadly to include the totality of exposures to combinations of environmental stressors and their effects on health and quality-of-life outcomes. Keeping pace with the Biden administration EPA’s environmental justice drive, key goals of the Interim Framework for Advancing Consideration of Cumulative Impacts include empowering EPA to (1) more fully and accurately characterize the realities communities face, (2) pinpoint the levers of decision making and identify opportunities for interventions that improve health and quality of life while advancing equity, and (3) increase meaningful engagement, improve transparency, and center actions on improving health and environmental conditions in communities.

Since the U.S. adoption of commercial nuclear power, large-scale commercial reactors — typically boiling or pressurized water designs — have been licensed under the provisions of 10 C.F.R. Part 50 (Part 50) and later 10 C.F.R. Part 52 (Part 52). Under these licensing approaches, license applicants submit construction and operating license permits in a multiyear process largely tailored to address the risks and controls necessary to operate bespoke, large-scale nuclear power plants at a specific site.
On October 22, 2024, the U.S. Environmental Protection Agency (EPA) published a final rule removing an affirmative defense from Clean Air Act (CAA) National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations for the Oil and Natural Gas Production Facility and Natural Gas Transmission and Storage Facility Source Categories (Final Rule).[1] Prior to the Final Rule, owners or operators could assert an affirmative defense that alleged NESHAP standard violations were caused by an equipment malfunction.[2] A “malfunction” is defined as any sudden, infrequent, and not reasonably preventable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner.[3]
