Proposition 65 Regulation (California)
Proposition 65 Regulatory OverviewProposition 65, formally known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was passed as a voter initiative with the purpose of protecting California citizens and the State’s drinking water sources from exposure to toxic chemicals. Proposition 65 requires California to publish a list of chemicals “known to the state” to cause cancer, birth defects or other reproductive harm. The list has grown to include roughly 800 chemicals since it was first published in 1987.
Once a chemical is listed, businesses must provide “clear and reasonable” warnings to those exposed in California and are prohibited from discharging it into drinking water, unless exposures are shown to be “insignificant.” The “significance” of potential exposures is determined by comparing them to allowable exposure levels, commonly called Safe Harbor Levels, or more specifically, No Significant Risk Level (NSRL) for carcinogens and the Maximum Allowable Dose Level (MADL) for chemicals causing reproductive harm. Proposition 65 affects every company conducting business in California, whether by manufacturing or distributing products for sale in the State or by operating businesses at facilities within the State.
Proposition 65 Enforcement
Proposition 65 may be enforced in California courts by public prosecutors, including the California Attorney General, district attorneys and certain city attorneys, or by any private individuals or groups acting “in the public interest.” Proposition 65 is enforced by litigation with the burden of proof placed on businesses rather than the plaintiff. Before a lawsuit is filed, a notice of the alleged violation must be sent to the business 60 days prior to the filing. This is known as a 60-day notice letter, during which the Attorney General may take over the case. Public prosecutors do not need to send 60-day notices. Because Proposition 65 is not enforced by a government agency, a business should seek legal advice upon receiving a 60-day notice letter. Violators are subject to civil penalties.
