Workshop on Proposition 65 listings via the Authoritative Bodies Mechanism

This workshop is being conducted by the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) to discuss issues related to the implementation of the authoritative bodies mechanism for listing under Proposition 65. The agenda was developed, in part, from comments received from interested parties. Agenda items are for discussion; some changes to the process or regulation may not be advisable or legally permissible.

The Proposition 65 statute requires the state to publish and update at least annually a list of chemicals known to cause cancer or reproductive toxicity. One of the mechanisms identified in the Proposition 65 statute is the listing of chemicals formally identified as causing cancer or reproductive toxicity by a body considered to be authoritative under Proposition 65 by the State’s qualified experts (i.e., the Carcinogen Identification Committee and Developmental and Reproductive Toxicant Identification Committee of the OEHHA Science Advisory Board). The regulatory guidance for listing by this mechanism is set forth in Title 22, California Code of Regulations (CCR), Section 12306. The authoritative bodies currently identified are the US Environmental Protection Agency, International Agency for Research on Cancer, National Institute of Occupational Safety and Health, US Food and Drug Administration, and National Toxicology Program.
