California's right-to-know and safe drinking water protection law, Proposition 65, must be extended to toxic chemicals known to cause cancer and reproductive harm that are already identified under worker protection standards, the Alameda County Superior Court has ruled.
The court held that California has an annual legal duty to update the Proposition 65 list with carcinogens and reproductive toxins identified under worker protection standards.
The court ruled in favor of labor and environmental groups, including the Natural Resources Defense Council, United Steelworkers and Sierra Club that fought the case against the California Chamber of Commerce.
"This is a victory for the health of all California families and communities, who have a right to know when they are exposed to chemicals that cause cancer and birth defects," said Michael Wall, senior attorney with the Natural Resources Defense Council. "This decision will prevent bureaucratic delays from standing in the way of health and drinking water protections."
Under Proposition 65, California annually publishes a list of chemicals that warns consumers of harmful substances and prohibits the discharges of listed chemicals into drinking water sources.
The list of chemicals California must now add to the Proposition 65 list is still in dispute, but more than 90 additional chemicals identified in workplace safety standards are at issue.
Chemicals that are likely to be listed as a result of this ruling include styrene, a ingredient in various plastic and foam products, gasoline additives such as tert-amyl methyl ether, and carbaryl, a common lawn and garden pesticide.
