What is Proposition 65?

In 1986, California voters passed Proposition 65, the Safe Drinking Water and Toxic Enforcement Act (”Prop 65”). Prop 65 prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water and requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. These chemicals may be in the products that Californians purchase, in homes or workplaces, or otherwise released into the environment. Per applicable requirements, the Office of Environmental Health Hazard Assessment (OEHHA) publishes a list of chemicals known to cause cancer, birth defects, or other reproductive harm (the Prop 65 List), including Safe Harbor levels below which notifications are exempted. 

Who must comply with Prop 65?

Proposition 65 applies to nearly any company that does business in California including industrial facilities, manufacturing, retail, restaurants, hotels, distributors, agriculture, amusement parks, and others. Since it was first published in 1987, the Prop 65 List has grown to include more than 900 chemicals. The list contains a wide range of naturally occurring and synthetic chemicals that include industrial solvents, common household products, food, drugs, dyes and others. Listed chemicals may also include byproducts of chemical processes such as motor vehicle exhaust.   Businesses are required to provide notification to consumers and workers regarding chemical exposures in their products, workplaces, or environmental releases, such as air pollution and water discharges. For more information on Proposition 65, visit the OEHHA website.
