The scope of products to be drawn into the warning requirements under California’s Proposition 65 law may soon be growing. California’s Office of Environmental Health Hazard Assessment (OEHHA) requested information from the public on the reproductive toxicity of p,p’-bisphenol chemicals. OEHHA is the lead agency for the implementation of Proposition 65, formerly known as the Safe Drinking Water and Toxicity Enforcement Act of 1986. OEHHA’s request for information is a step toward regulators classifying all p,p’-bisphenol chemicals as reproductive toxicants under Proposition 65.

California’s Proposition 65
Under Proposition 65, businesses are required to post clear and reasonable warnings before individuals are exposed to chemicals listed by the state of California as carcinogens or reproductive toxicants. To date, California has listed approximately 900 chemicals that fall under Proposition 65 regulation. Businesses may be held liable for up to $2,500 per violation per day. Proposition 65 can be enforced by public prosecutors (e.g., the California attorney general or district attorneys) or by private enforcers (known as “bounty hunters”).
