On April 19, the U.S. Environmental Protection Agency (EPA) released a pre-publication version of the long-awaited final rule designating two per- and polyfluoroalkyl substances (PFAS) as “hazardous substances” under the Comprehensive Environmental Response, Cleanup, and Liability Act (CERCLA). This final rule comes right on the heels of EPA’s April 8 announcement of the final rule setting maximum contaminant levels (MCLs) for six PFAS under the Safe Drinking Water Act (SDWA). Our detailed summary of the MCL final rule is available here.Continue Reading PFAS Designated as CERCLA Hazardous Substances

On April 8,  U.S. Environmental Protection Agency (EPA) Administrator Michael S. Regan signed a final rule regulating six per- and polyfluoroalkyl substances (PFAS) under the Safe Drinking Water Act (SDWA). The final rule, which will become effective 60 days after publication in the Federal Register, sets individual maximum contaminant levels (MCLs) for PFOA and PFOS at 4.0 nanograms per liter (ng/L), and for PFHxS, PFNA, and HFPO-DA at 10 ng/L. In addition to these individual MCLs, the rule establishes a hazard index (HI) of one (unitless) as the MCL for any mixture containing two or more of PFHxS, PFNA, HFPO-DA, and PFBS. Under the rule, regulated public water systems (PWS) must conduct and report their initial monitoring within three years after publication, and make any necessary capital improvements to comply with the MCLs within five years after publication.Continue Reading PFAS MCL Summary

On October 18, U.S. Environmental Protection Agency’s (EPA) Office of Chemical Safety and Pollution Prevention submitted a final rule for publication in the Federal Register, amending 40 CFR Part 372, involving reporting requirements for per- and polyfluroalkyl substances (PFAS) and supplier notifications for chemicals of special concern. The rule becomes effective 30 days after publication and applies to the reporting year 2024, with reports due July 1, 2025.Continue Reading US EPA Issues Final Rule on PFAS Relating to Community Right-to-Know and Pollution Prevention Acts

Michigan Attorney General (AG) Dana Nessel has filed suit against the Gerald R. Ford International Airport Authority to enforce demands by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) related to alleged per- and polyfluoroalkyl substance (PFAS) contamination of the regional drinking water supply caused by the airport authority.Continue Reading Michigan AG Brings PFAS Lawsuit Against the Gerald R. Ford International Airport Authority

Public water utilities and 3M have until August 28 to respond to the bipartisan coalition of 22 state attorneys general (AGs) that opposes their proposed $12.5 billion class action settlement over alleged per- and polyfluoroalkyl substance (PFAS) contamination and is seeking to intervene in their litigation.Continue Reading Plaintiffs and 3M Given August 28 Deadline to Respond to State AGs’ Opposition to $12.5B Settlement in the PFAS Multidistrict Litigation

On August 7, California Attorney General Rob Bonta led a coalition of five state attorneys general (AGs) in filing an amicus letter concerning a proposed class action settlement between DuPont, Chemours, and Corteva, and water providers for $1.185 billion. The AGs contend the settlement amount is far too low given the scope of environmental contamination and health impacts caused by Dupont’s decades-long manufacture and sale of per- and polyfluoroalkyl substances (PFAS) compounds.Continue Reading Five State AGs Write Amicus Letter Concerning Environmental Settlement

A bipartisan coalition of attorneys general (AGs) from 22 states is urging the federal district court in South Carolina to reject a proposed $12.5 billion settlement between 3M and a group of public water utilities, who are suing the company over alleged per- and polyfluoroalkyl substance (PFAS) contamination.Continue Reading Coalition of 22 State AGs Oppose 3M’s $12.5 Billion PFAS Settlement

On March 13, the Environmental Protection Agency (EPA) took the long-anticipated step of proposing maximum contaminant level goals (MCLGs), as well as individual maximum contaminant levels (MCLs), for six PFAS compounds under the Safe Drinking Water Act. PFAS are a large family of synthetic chemicals that have been in use since the 1940s. Many PFAS have unique physical and chemical properties that make them highly stable and resistant to degradation in the environment, which is why they are sometimes referred to as “forever chemicals.”Continue Reading EPA Advances PFAS Strategic Roadmap With Proposed Drinking Water Standards

On October 28, the EPA published the Final Fifth Drinking Water Contaminant Candidate List. Under the Safe Drinking Water Act (SDWA), the EPA is required to publish a new Contaminant Candidate List (CCL) every five years. The CCL contains a list of contaminants that are currently not subject to any national primary drinking water regulations but are anticipated to occur in public water systems and may require regulation.Continue Reading EPA Publishes Final Fifth Drinking Water Contaminant Candidate List (CCL)
