The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment will convene a meeting of the Developmental and Reproductive Toxicant Identification Committee for possible listing of perfluorononanoic acid (PFNA) and its salts, and perfluorodecanoic acid and its salts, under the Safe Drinking Water and Toxic Enforcement Act of 1986. This will also opening a 45-day public comment period on the hazard identification document for these chemicals.
Proposition 65
Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The proposition protects the state's drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals.
Proposition 65 requires the state to maintain and update a list of chemicals known to the state to cause cancer or reproductive toxicity.
