From the California Dental Association Executive Bulletin, January 12, 2010:

Specifically, ADA granted CDA $200,000 to assist in our effort to prevent the placement of fluoride and its salts on the List of Chemicals Known to the State to Cause Cancer or Reproductive Toxicity that is produced by the State of California, Environmental Protection Agency, Office of Environmental Health Hazard Assessment (OEHHA). The Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) requires the governor to publish this list of toxic chemicals each year. OEHHA is currently considering fluoride and its salts for inclusion in the Proposition 65 listing. A determination is expected within the next 13 months.
