1986 California Proposition 65


Proposition 65 (formally titled The Safe Drinking Water and Toxic Enforcement Act of 1986, and also referred to as Prop 65) is a California law passed by direct voter initiative in 1986 by a 63%–37% vote. Its goals are to protect drinking water sources from toxic substances that cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, such as consumer products, by requiring warnings in advance of those exposures.


California Proposition 65 Warning before August 31, 2018 [1]

Proposition 65 is administered by Cal/EPA's California Office of Environmental Health Hazard Assessment (OEHHA).[2] Proposition 65 regulates substances officially listed by California as causing cancer or birth defects or other reproductive harm, in two ways. The first statutory requirement of Proposition 65 prohibits businesses from knowingly discharging listed substances into drinking water sources, or onto land where the substances can pass into drinking water sources. The second prohibits businesses from knowingly exposing individuals to listed substances without providing a clear and reasonable warning. The requirements apply to amounts above what would present a 1-in-100,000 risk of cancer assuming lifetime exposure (for carcinogens), or above one-one-thousandth (1/1000) of the no observable effect level (for reproductive toxins).[3]

An official list of substances covered by Proposition 65 is maintained and made publicly available. Chemicals are added to or removed from the official list based on California's analysis of current scientific information. All substances listed show their known risk factors, a unique CAS chemical classification number, the date they were listed, and, if so, whether they have been delisted.[4]

1986 Protest against Proposition 65

Proposition 65 has been highly successful in reducing exposures to known toxic chemicals, especially in consumer products, and its successes illustrate gaps in the effectiveness of federal toxics laws (see Accomplishments below). It remains politically controversial even after more than 30 years (see Controversy and claimed abuse below), in large part because business objects to Proposition 65's burden of proof[citation needed] , which in effect requires businesses to know the scientific safety level for specific cancer- and birth defect-causing chemicals that those businesses are intentionally exposing members of the public to, unless government has already set those levels.[5] According to the California Environmental Protection Agency, "Proposition 65 has... increased public awareness about the adverse effects of exposures to listed chemicals.... [and] provided an incentive for manufacturers to remove listed chemicals from their products.... Although Proposition 65 has benefited Californians, it has come at a cost for companies doing business in the state."[6]

Rationale and enumerated rightsEdit

In addition to amending the California Health and Safety Code, Proposition 65 contained the following language in the 1986 ballot initiative:[7]

SECTION 1. The people of California find that hazardous chemicals pose a serious potential threat to their health and well-being, that state government agencies have failed to provide them with adequate protection, and that these failures have been serious enough to lead to investigations by federal agencies of the administration of California's toxic protection programs. The people therefore declare their rights:
(a) To protect themselves and the water they drink against chemicals that cause cancer, birth defects, or other reproductive harm.
(b) To be informed about exposures to chemicals that cause cancer, birth defects, or other reproductive harm.
(c) To secure strict enforcement of the laws controlling hazardous chemicals and deter actions that threaten public health and safety.
(d) To shift the cost of hazardous waste cleanups more onto offenders and less onto law-abiding citizens.

The people hereby enact the provisions of this initiative in furtherance of their rights.

The Legislature's 2003 amendments to Proposition 65 contained the statement that the changes "further the purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986."[8]


Enforcement is carried out through civil lawsuits against Proposition 65 violators. These lawsuits may be brought by the California Attorney General, any district attorney, or certain city attorneys (those in cities with a population exceeding 750,000). Lawsuits may also be brought by private parties "acting in the public interest," but only after providing notice of the alleged violation to the Attorney General, the appropriate district attorney and city attorney, and the business accused of the violation.

A Proposition 65 Notice of Violation must provide adequate information to allow the recipient to assess the nature of the alleged violation. A notice must comply with the information and procedural requirements specified in regulations. A private party may not pursue an enforcement action directly under Proposition 65 if one of the government officials noted above initiates an action within sixty days of the notice.[9][10] After 2003, private enforcers must also serve a certificate of merit (statement of expert consultation(s) supporting belief of reasonable and meritorious private action) as a means of preventing frivolous enforcement actions.

A business found to be in violation of Proposition 65 is subject to civil penalties of up to $2,500 per day for each violation. In addition, the business may be ordered by a court of law to stop committing the violation.[11] Other penalties may apply, including unfair business practices violations as limited under California Proposition 64 (2004).

Businesses can become compliant by learning upfront whether or not their products contain chemicals that match the current Proposition 65 list of 910 chemicals. Users can do this by searching in a Microsoft Excel[12] chemical list or a website offering the search by chemical name or CAS Number.[13] Product manufacturers may also learn if a chemical in their products has been removed from the Proposition 65 list, such as saccharin, removed December 2010.[14]


Proposition 65 has caused large numbers of consumer products to be reformulated to remove toxic ingredients, as documented in settlements of enforcement actions.[15] The law's author stated that many more product reformulations have taken place "invisibly," because of Proposition 65's incentive to reduce toxic exposures in advance of enforcement, and that product reformulations have benefitted consumers nationwide, not just in California.[16]

In the law's first ten years of operation, emissions of its listed chemicals into the air were reduced much more in California (~85%) than in the rest of the U.S. (~50%), as tracked by the U.S. Toxics Release Inventory.[17] California's air emissions during the same period of other toxic chemicals, also tracked by TRI but not on the Proposition 65 list, declined by only the national average,[18] strongly indicating that Proposition 65 was the cause of the difference.

Proposition 65 has also caused government and industry to cooperate on scientific issues of chemical risk, resulting in risk-based standards for 282 toxic chemicals in the law's first few years of operation, an accomplishment described by a Governor's Task Force as "100 years of progress [by federal standards] in the areas of hazard identification, risk assessment, and exposure assessment."[19] The existence of clear numerical standards has significantly assisted efforts to comply with the law, and to enforce it in situations of non-compliance.

Notably, nearly all of the reductions in toxic exposures caused by Proposition 65 have occurred in areas also subject to federal laws and regulations intended to control toxic chemicals, reductions which those federal controls had failed to achieve.[20]

Warning labelEdit

Warning label since 31. Aug. 2018

The following warning language is standard on products sold in California if they contain chemicals on the Proposition 65 list and the amount of exposure caused by the product is not within defined safety limits:

WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

The wording can be changed as necessary, as long as it communicates that the chemical in question is known to the state to cause cancer, or birth defects or other reproductive harm. For exposures from other sources, such as car exhaust in a parking garage, a standard sign might read: "This area contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm".[21]

Controversy and claimed abuseEdit

Political controversy over the law, including industry attempts to have it preempted by federal law, have died down, although preemption bills continue to be introduced in the U.S. Congress, most recently H.R. 6022 [22] (introduced June 6, 2018). However, enforcement actions remain controversial. Many Proposition 65 complaints are filed on behalf of straw man plaintiffs by private attorneys, some of whose businesses are built entirely on filing Proposition 65 lawsuits.[23][24][25]

The law has also been criticized for causing "over-warning"[26] or "meaningless warnings,"[27][28][29] and this risk has been recognized by a California court.[23][30] There is no penalty for posting an unnecessary warning sign,[31] and to the extent that warnings are vague or overused, they may not communicate much information to the end user.[26] The law's principal author notes that in practice, businesses have overwhelmingly chosen to reduce or eliminate their toxic exposures, rather than giving warnings about them, due to market forces.[32] Examples of warning signs can be found at gas stations,[27] hardware suppliers,[33] grocery stores, drug stores, medical facilities,[34] parking garages, hotels,[26] apartment complexes,[35] retail stores,[36] banks, and restaurants,[37] warning about hazardous chemicals in items for sale, or present in the immediate environment. Utility companies mail a Prop 65 notice to all customers each year to warn them about exposures to natural gas, petroleum products[38] and sandblasting.[39]

Abuse of enforcement lawsuits has also been a consistent theme of Proposition 65 opponents, who criticize the motives of citizen enforcers. Industry critics and corporate defense lawyers charge that Proposition 65 is "a clever and irritating mechanism used by litigious NGOs and others to publicly spank politically incorrect opponents ranging from the American gun industry to seafood retailers, etc."[40] Critics also note that the majority of settlement money collected from businesses has been used to pay plaintiffs' attorney fees.[41] Businesses paid over $14.58 million in attorney fees and costs in 2012, 71% of all settlement money paid.[42]

Because the law allows private citizens to sue and collect penalties from any business violating the law, lawyers and law firms have been criticized for using Proposition 65 to force monetary settlements out of Californian businesses.[43] In the past the Attorney General's office has cited several instances of settlements where plaintiff attorneys received significant awards without providing for environmental benefit to the people of California, resulting in a requirement that the Attorney General's office must approve any pre-trial Proposition 65 settlement.[44]

Recent reform effortsEdit

In the 2013–14 session of the California State Assembly, a consensus bill, AB 227, introduced by Assemblyman Mike Gatto (D-Los Angeles), effectively offered to protect certain small companies in specified circumstances from the threat of citizen enforcement lawsuits, by providing them with a streamlined compliance procedure and limited penalties. The bill was passed unanimously, with support from Proposition 65 proponents and supporters, and was enacted on October 10, 2013.[45]

Following the success of AB 227, Gov. Jerry Brown announced on May 7, 2013 that his office plans to introduce a proposal to reform Proposition 65.[46] In 2017, Brown advocated for more reform to Prop 65 to reduce "frivolous shakedown lawsuits."[47]

Reformulation of consumer goodsEdit

Over the years, Prop 65 has led to consent agreements for a variety of consumer products, such as bibs, bicycles, products containing brass, cookware, cosmetics, exercise mats, ceramic ware and glassware, clothing, fake leather upholstery, headphone cables, jewelry, lunchboxes, poker chips, luggage, and accessories.

In early 2011, a number of new Prop 65[48] consent agreements were reported, covering vinyl inflatable structures, vinyl lounge chairs, inspection lights with clamp handles, brass door handles, cadmium in jewelry and a revised judgment for fashion accessories.

In the latter part of 2011, further consent agreements were reported. These included reformulation of up to 1000 ppm DEHP for book covers and jackets. Further reformulations for lead content also concluded. For fashion jackets and belts with components that can be handled, touched or mouthed, two tests are necessary for compliance: less than 1.0 μg lead using method NIOSH 9100 and less than 100 ppm lead using EPA 3050B.

More recently, since December 2011 and during the first half of 2012, a further number of consent settlements for Prop 65 have been concluded, enforcing reformulation of a range of additional products by specifying the limits of heavy metals and organic chemicals.

Alleged violatorsEdit

As of 2019, the below list includes some of the named Fortune 500[49] companies that have been sued or received an intent to sue for allegedly not disclosing the Prop 65 warning on one or more of their products.[50][51][47][52] The list includes, but is not limited to:[53]

In most cases, such as McDonald's, Walgreens, and Disney, the listed chemicals have been removed.[51] "As of August 2019, Amazon faces over 1,000 Prop 65 'Intent to Sue' notices."[54] E-commerce marketplaces, like Amazon, require their sellers to disclose if their products contain Prop 65 chemicals. However, these companies are currently under fire for some of their sellers allegedly not disclosing Prop 65 chemicals that are in their brands.[64]

List of chemicalsEdit

Proposition 65 requires that the governor revise and republish at least once per year the list of chemicals known to the State to cause cancer or reproductive toxicity.[65]

There also exists a "Safe harbor List" with tolerance thresholds for some of the chemicals named in the Proposition 65 list. Concentrations under the tolerance threshold do not legally require the warning label.[66]

Virtually every business has some sort of Prop 65 warning sign posted, and innumerable products are labeled with the warning.

They are not told either the degree of exposure or the likelihood that they may actually be impacted by it.
