UPDATE: EPA Takes Next Step in PFAS Regulations – Proposing Adding Nine PFAS as Hazardous Constituents

On January 31, 2024, the U.S. Environmental Protection Agency (EPA) announced that it is proposing to list nine per- and polyfluoroalkyl substances (PFAS) as hazardous constituents under the Resource Conservation and Recovery Act (RCRA). This action represents another significant step in the regulation of PFAS.

PFAS are a key focus of many environmental regulators and of many people as well largely based on their ubiquity and catchy nickname “forever chemicals.” Both come from the fact that PFAS do not break down naturally over time either in the environment or in the human ...

Upcoming Deadlines for Water Agencies for PFAS Settlements

Deadlines are upcoming related to the multi-district per- and polyfluoroalkyl substances (PFAS) litigation. The relevant settlements are with DuPont, Chemours, and Corteva (collectively, DuPont) and 3M, parties who allegedly manufactured various PFAS chemicals. The currently-pending settlements cover $1.185 billion for DuPont and $10.5-$12.5 billion for 3M.

The litigation is focused on alleged contamination of drinking water caused by DuPont’s and 3M’s alleged manufacture of PFAS chemicals. PFAS are a family of manmade chemicals that are used due to beneficial ...

EPA Finalizes PFAS Reporting Requirements

On September 28, 2023, the U.S. Environmental Protection Agency (EPA) finalized its rule requiring reporting of per- and polyfluoroalkyl substances (PFAS). According to EPA’s press release, the rule is intended to “provide EPA, its partners, and the public with the largest-ever dataset of [PFAS] manufactured and used in the United States.”

Ninth Circuit Reverses Previous Decision on RCRA Liability for Water Supplier

On July 1, 2022 a panel of the Ninth Circuit issued a superseding opinion in California River Watch v. City of Vacaville, Appeal No. 20-16605, withdrawing its previous opinion in the same case and reaching the opposite result. The case is a rare example of a court reversing itself, and has important implications for water suppliers in California and nationwide.

In California River Watch, the plaintiff sought to impose RCRA liability on a water supplier based on the presence of hexavalent chromium in the water it supplied to customers, despite the fact that the water complied with the ...

Water Board Adopts Final Definition of Microplastics in Drinking Water

This week, on June 16, the California State Water Resources Control Board (“State Water Board”) unanimously adopted a definition for microplastics, making California the first state to adopt a definition specifically applied to drinking water (footnotes omitted):

‘Microplastics in Drinking Water’ are defined as solid polymeric materials to which chemical additives or other substances may have been added, which are particles which have at least three dimensions that are greater than 1nm and less than 5,000 micrometers (µm). Polymers that are derived in nature that have not been chemically modified (other than by hydrolysis) are excluded.

The final definition is much the same as the proposed version that was issued in March 2020 for public comment, key differences being that ...
