In 2023, Minnesota enacted Amara’s Law (Minn. Stat. § 116.943), requiring certain reporting and implementing prohibitions of intentionally-added PFAS in certain products. The law requires manufacturers of intentionally-added PFAS-containing products to report specified information to the Minnesota Pollution Control Agency (MPCA) by January 1, 2026. These reports must include the type of PFAS added to the product and its purpose in the product. In June, the MPCA stated its intent to extend the reporting deadline, but did not…

The Fourth Circuit overturned the remand of two lawsuits Maryland and South Carolina brought against 3M and other PFAS manufacturers. Maryland v. 3M Co., No. 24-1218, 2025 WL 727831 (4th Cir. Mar. 7, 2025). The ruling expands the reach of the federal officer removal statute, making it easier for certain defendants to remove their cases to federal court.

Maryland and South Carolina each brought two PFAS-related lawsuits against 3M: one involving claims arising from AFFF contamination, and another limited…

Those required to comply with certain reporting and recordkeeping requirements for per- and polyfluoroalkyl substances (PFAS) under the Toxic Substances Control Act (TSCA) have been afforded an eight-month delay, shifting reporting to commence July 11, 2025, and be completed by Jan. 11, 2026. Reporting was supposed to commence Nov. 12, 2024, before this delay was announced by the Environmental Protection Agency (EPA). The delay is driven by funding shortages leading to delays in the reporting software development.

EPA is requiring additional testing at sites subject to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, or Superfund) five-year review based on PFAS standards issued under the Safe Drinking Water Act (SDWA).

In April 2024, EPA finalized a rule designating two of the most studied and prevalent PFAS,  Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonic acid (PFOS), as hazardous substances under CERCLA. The rule was published May 8, 2024, and became effective July 8, 2024. 40 CFR § 302.4(a).

On May 1, 2024, Colorado became the thirteenth state to pass legislation banning per- and polyfluoroalkyl substances, commonly referred to as PFAS. The move comes shortly after PFAS received exceptional public attention when EPA finalized its first-ever national drinking water standards for six PFAS this past April. The release of these new standards now requires states and industry to act quickly and strategically on plans to restrict PFAS from water systems. For Colorado, multiple areas across the state detected PFAS in the water beyond EPA limits when EPA required water systems across the nation to test for dozens of PFAS last year.Continue Reading Colorado Bans Forever Chemicals After EPA Sets New PFAS Water Standards

Since EPA announced a Final Rule designating certain per- and polyfluoroalkyl substances (PFAS) as hazardous substances, there has been ample national attention on what the legal and regulatory landscape would look like in restricting these dangerous substances. Various states have taken independent action to curtail the significant health and environmental risks posed by PFAS. Recently, Vermont moved to further restrict the prevalence of PFAS in products sold in their state.Continue Reading Vermont Legislature Takes Action to Limit PFAS in Common Commercial Products

The State of Michigan recently took another step aimed at protecting the environment and public health from the impact of per- and polyfluoroalkyl substances (PFAS). Last week, State Rep. Penelope Tsernoglou (D-East Lansing) and Majority Floor Leader Abraham Aiyash (D-Hamtramck) introduced The Hazardous Products Act under House Bill 5657 (the “Legislation”), which would prohibit, the sale and distribution of products containing intentionally added PFAS by Jan. 1, 2027, including, without limitation, cookware, cosmetics, and children’s products. The Legislation would also prohibit the discharge or use of PFAS-containing class A or class B firefighting foam by Jan. 1, 2027. The Legislation has roughly 20 co-sponsors and was referred to the Michigan House’s Natural Resources Committee.

If enacted, the Legislation would ban the sale of products that contain intentionally added PFAS. The Legislation defines “PFAS” as a “perfluoroalkyl or polyfluoroalkyl substance that includes any member of the class of fluorinated organic chemicals containing at least 1 fully fluorinated carbon atom.” Under the Legislation, PFAS is intentionally added if the PFAS added by a manufacturer “has a functional or technical effect on a product, or a component thereof, or the manufacturing process. Intentionally added PFAS includes any PFAS that is a component or a breakdown product of an intentionally added chemical that has a functional or technical effect on the product, or a component thereof, or the manufacturing process.”Continue Reading Michigan Takes Step to Limit PFAS Through Hazardous Products Act

On April 10, 2024, U.S. EPA announced a National Primary Drinking Water Regulation (NPDWR) establishing legally enforceable Maximum Contaminant Levels (MCLs) and non-enforceable Maximum Contaminant Level Goals (MCLGs) for six per- and polyfluoroalkyl substances (PFAS) in drinking water under the Safe Drinking Water Act (SDWA).

The final rule requires public water systems to: (1) complete initial monitoring for these PFAS by 2027 and provide public notice of initial monitoring results beginning in 2027; (2) implement solutions by 2029 to reduce these PFAS if drinking water levels exceed the MCLs; and (3) starting in 2029, take action to reduce PFAS in response to violations of the MCLs and to provide public notice of any such violations.

On April 19, 2024, the U.S. Environmental Protection Agency (EPA) announced the pending publication of a final rule designating two widely used per-and polyfluoroalkyl substances (PFAS) chemicals—perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS)—as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This announcement comes approximately a year and a half after EPA initially proposed the designation of PFOA and PFOS as CERCLA hazardous substances via EPA’s publication of its proposed rule in late 2022.Continue Reading EPA Announces Final Rule Designating PFOA and PFOS as Hazardous Substances Under CERCLA

On April 10, 2024, the U.S. EPA released its federally enforceable drinking water limits for certain toxic PFAS “forever chemicals” under the federal Safe Drinking Water Act. The final rule will “reduce PFAS exposure for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious illnesses.”

Taft partner, author, and advocate Rob Bilott stated, “Today we can celebrate a huge victory for public health in this country. The U.S. EPA is moving forward to protect…
