California Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, is a California state law that addresses public exposure to chemicals known to cause cancer, reproductive harm, or other developmental issues. Proposition 65 requires businesses to provide warnings to individuals about significant exposures to listed chemicals that may result from their products or activities.

Key points regarding California Proposition 65 include:

  1. List of Chemicals: The law maintains a list of chemicals known to the state to cause cancer, reproductive toxicity, or both. The list is regularly updated, and it currently includes over 900 chemicals.
  2. Warning Requirement: Businesses are required to provide a “clear and reasonable warning” before knowingly and intentionally exposing individuals to listed chemicals at levels that exceed established “safe harbor” thresholds. The warning is typically provided on product labels, signs, or through other means, depending on the nature of exposure.
  3. Exposures Triggering Warnings: Warnings are required for exposures from various sources, including consumer products, building materials, workplace exposures, and environmental discharges. The focus is on exposures that result in significant risk levels.
  4. Private Enforcement: Proposition 65 allows private citizens, advocacy groups, and the California Attorney General to enforce its provisions. Private enforcers can bring lawsuits against businesses alleged to be in violation of the warning requirements.
  5. Penalties and Settlements: Businesses found to be in violation of Proposition 65 may face penalties and fines. Many cases are resolved through settlements, where businesses agree to reformulate their products, provide warnings, or take other actions to reduce exposures.
  6. Safe Harbor Levels: The Office of Environmental Health Hazard Assessment (OEHHA) establishes “safe harbor levels” for many listed chemicals. If exposures are below these levels, warnings may not be required. Safe harbor levels are typically based on risk assessments.
  7. Preemption: Proposition 65 does not preempt federal law. Businesses must comply with federal regulations, but compliance with federal requirements does not necessarily exempt a business from Proposition 65 requirements.
  8. Public Database: OEHHA maintains a public database that provides information on chemicals covered by Proposition 65, including their safe harbor levels and exposure routes.

Businesses, particularly those that manufacture or sell products in California, need to be aware of Proposition 65 requirements. They may need to assess their products for the presence of listed chemicals, determine if warnings are necessary, and take appropriate actions to comply with the law. Proposition 65 has significant implications for businesses and consumers in California, and it is designed to inform and protect the public from exposure to harmful chemicals.
