(Note: This update involves recent developments on a topic covered in a December 2021 client alert.)
As advised in part by the Biden Administration, developments in the regulation of per- and polyfluoroalkyl substances (PFAS) continue to unfold. Not only did the EPA release its PFAS Strategic Roadmap in October, but it has proposed a potentially significant rulemaking under the Resource Conservation and Recovery Act, initiated a scientific review of the adequacy of its current health advisory level for the two most studied PFAS—perfluorooctanoic (PFOA) acid and perfluorooctane sulfonic acid (PFOS)—and taken steps toward establishing a technical foundation for regulating PFAS air emissions under the Clean Air Act. (Additional impetus for the last action derives from pending congressional legislation.) Additionally, a recent federal court decision in the Northern District of Georgia stands to increase the liability exposure of secondary manufacturers and processors of PFAS products in connection with toxic tort suits involving negligence claims. Meanwhile, state attorneys general are urging continued congressional effort to pass a comprehensive PFAS bill that would expedite and fund several of the PFAS regulatory actions contemplated by EPA.
