PFAS.2025@deq.oregon.gov This rulemaking proposes to include two per- and polyfluoroalkyl substances (PFAS), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, in the definition of hazardous substances in Oregon Administrative Rule (OAR) 340-122-0115 (30) which would give the Department authority to require investigation and removal and remedial actions of PFOA and PFOS releases and align with the US Environmental Protection Agency's approach. PFOA and PFOS are among the most commonly detected PFAS, are known or suspected carcinogens, and have been shown to exhibit toxicity effects to humans and wildlife even at low levels of exposure.
