"Effective February 25, 2022, for purposes of Proposition 65, the Office of Environmental Health Hazard Assessment (OEHHA) is adding perfluorooctanoic acid (PFOA) (CAS RN 335-67-1) to the list of chemicals known to the State of California to cause cancer.

The listing of perfluorooctanoic acid (PFOA) is based on its formal identification by the National Toxicology Program (NTP), an authoritative body for purposes of Proposition 65, that the chemical causes cancer. The criteria used by OEHHA for the listing of chemicals under the “authoritative bodies” mechanism can be found in Title 27, Cal. Code of Regs., section 25306.

The basis for the listing was described in a public notice published in the March 19, 2021, issue of the California Regulatory Notice Register (Register 2021, No. 12-Z). The title of the notice was “Notice of Intent to List Chemical by the Authoritative Bodies Mechanism: Perfluorooctanoic Acid.” The publication of the notice initiated a 45-day public comment period. OEHHA received five sets of comments during the comment period. The comments and OEHHA’s responses are posted below.

A complete, updated Proposition 65 chemical list is available."
