U.S. Environmental Protection Agency Announces New PFAS Action Plan
On April 28, 2025, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced the Agency’s plan to address per- and polyfluoroalkyl substances (PFAS) during the second Trump Administration. PFAS are manmade chemicals—of which there are thousands—commonly found in textiles, cookware, packaging, plastics, and firefighting foams. These “forever chemicals” are persistent in the environment and human body, as they do not break down and can accumulate over long periods of time. EPA’s outlined action plan calls upon its investigatory, regulatory, and enforcement powers under various statutes, including the Toxic Substances Control Act (TSCA), Clean Water Act (CWA), Safe Drinking Water Act (SDWA), Resource Conservation and Recovery Act (RCRA), and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).
New York Passes Second-in-the-Nation Climate Change Superfund Act
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.
Vermont and New York Climate Acts are First in a Wave of Likely Climate Change Cost Recovery Laws
On May 30, 2024, Vermont’s Republican governor, Phil Scott, allowed Vermont’s S 259 — also referred to as the “Climate Superfund Act” — to become law without his signature. The stated goal of this law is to mitigate the impacts of climate change.
Spring 2023 Agenda Previews Continued U.S. Significant Environmental Regulatory Action
On June 13, 2023, the Biden administration released the 2023 Spring Unified Agenda of Regulatory and Deregulatory Actions (Agenda). The Agenda lists federal agencies’ planned “short-term” regulatory actions to be taken over the next 12 months and “long-term” actions under development. The dates listed in the Agenda are based on publication dates in the Federal Register. Stakeholders should take note, as the Agenda provides a window into the administration’s priorities and strategies:
EPA Seeks Public Input on Regulating Seven More PFAS for Superfund
On April 13, 2023, the U.S. Environmental Protection Agency (EPA) issued an Advance Notice of Proposed Rulemaking (ANPRM) asking the public for input concerning potential designations of seven per- and polyfluoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Based on public input and data to be received, EPA will evaluate whether these PFAS may present substantial danger to the public health or welfare or the environment.
EPA Amends All Appropriate Inquiries Rule
On December 15, 2022, the U.S. Environmental Protection Agency (EPA) published a Final Rule to amend its All Appropriate Inquiries (AAI) Rule. The AAI Rule is the EPA regulation that sets the process for conducting an inquiry into a property’s environmental conditions in order to obtain protections from liability under the federal Superfund Law, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The amended rule updates the reference to the latest American Society for Testing and Materials (ASTM) E1527-21 Standard Practice as one method for conducting a Phase I Environmental Site Assessment (Phase 1 ESA) that would satisfy EPA’s AAI requirements. The rule takes effect on February 13, 2023 — but allows a one-year transition before EPA will no longer accept the former ASTM Phase I ESA standard (E1527-13) as meeting the AAI requirement.
D.C. Circuit Rejects Challenge to CERCLA Site Listing
On July 8, 2022, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) rejected a challenge to the listing of a groundwater contamination plume on the National Priorities List (NPL). The decision in Daikin Applied Americas, Inc. v. EPA reaffirms the difficulty that attends challenging NPL listings as well as the wide latitude Congress granted the Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to define the scope of Superfund sites during the listing process.
