On June 15, 2022, the United States Environmental Protection Agency (EPA) released drinking water health advisories [1] for certain per- and polyfluoroalkyl substances (PFAS), resulting in the establishment of:

  1. Near zero updated interim advisory levels for Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonic acid (PFOS) that are not only orders of magnitude below previously established levels, but that are also below detectable levels and, notably, were issued in advance of completion of peer review by EPA’s Science Advisory Board (SAB); and
  2. Newly issued final advisories at low levels for GenX and PFBS chemicals that have been used as replacement chemicals for PFOA and PFOS.

11.22.21 Last week, EPA transmitted four important documents to the EPA Science Advisory Board (SAB) for peer review that included updated health assessments for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). This peer review, which will start on December 16, will inform EPA’s development of a Maximum Contaminant Level (MCL) Goal and a future, legally enforceable National Primary Drinking Water Regulation for PFOA and PFOS under the Safe Drinking Water Act. As noted in the PFAS Strategic Roadmap: EPA’s Commitments to Action 2021-2024, EPA intends to release a proposed drinking water regulation for PFOA and PFOS in fall 2022. These scientific documents will provide the underpinnings for that important regulation.

California’s Proposition 65 (Prop 65), adopted in 1986 by state voters, has long been considered among the most far-reaching right-to-know and toxic chemical reduction statutes in the country. It now has competition from Washington State’s Pollution Prevention for Healthy People and Puget Sound Act (the “Act”), SSB 5135 (Chapter 292, 2019 Laws), signed into law on May 8, 2019, by former 2020 presidential candidate Governor Jay Inslee. Numerous commentators have called the Act, the nation’s “strongest” policy for regulating toxic chemicals in consumer products.

Despite the many benefits of PFAS, there continues to be a rise in regulatory action, legal implications and environmental, health and safety concerns related to the “forever chemicals.” Hunton Andrews Kurth attorneys Dan Grucza and Chuck Knauss give an inside look into the changing regulatory landscape of PFAS.

On Thursday, July 11, 2019, the House of Representatives approved amendments to the fiscal 2020 National Defense Authorization Act to address contamination from PFAS chemicals.

Per- and polyfluoroalkyl (PFAS) chemicals are colloquially known as “forever” chemicals due to their ability to build up and to persist over time. PFAS chemicals regulated under this bill have long been used to manufacture a wide range of products, like firefighting foam, cookware, stain repellents, apparel and food packaging and wrappers.

Effective July 13, 2018, the California State Water Resources Control Board’s Division of Drinking Water (DDW) established drinking water notification levels of 14 ppt for PFOA and 13 ppt for PFOS, and a combined PFOA/PFOS drinking water response level of 70 ppt. Notification and response levels are non-binding, health-based advisory levels for contaminants in drinking water where maximum contaminant levels (MCLs) have not been promulgated. Establishment of notification and response levels often is the DDW’s first step toward adopting binding MCLs.

New chemicals of concern, new scientific and technical developments, newly discovered wastes, or natural disasters can add up to new CERCLA liabilities. When the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”) was passed in 1980, it did not address the finality of judgments and settlements for the cleanup of contaminated sites. Some early settlements with EPA provided a complete release from all future CERCLA liability, but that later changed when the United States Environmental Protection Agency (“EPA”) began to limit the scope of covenants not to sue to specified “matters covered” by the settlement. The 1986 CERCLA amendments in section 122(f)(6), 42 U.S.C. § 9622(f)(6)(1) permanently made the change to require “reopeners” in all but a few limited circumstances.
