California bans polycarbonate manufacture-starting material

The State of California in the United States on 11 May relisted Bisphenol A (BpA) on its Proposition 65 list of substances known to the state to cause cancer, birth defects or reproductive toxicity.

Bisphenol A is primarily used to make plastics and is officially relisted as a potentially-hazardous chemical which requires a warning label to comply with California Safe Drinking Water and Toxic Enforcement Act.

The state took that new action notwithstanding the continued existence of a lawsuit brought by the American Chemistry Council and others to enjoin the state's first attempt to list BpA.

The chemical is of note to members of the optical industry because it is used as a starting material in the manufacture of polycarbonate, used in manufacture of lenses.

The Prop 65 warning requirement for BpA takes effect one year after the chemical is added to the list, so companies will now have until 11 May 2016 to determine if their products sold in California contain BpA, or if their California work places will expose employees to BpA.

The Vision Council is in the process of reviewing the new listing, especially to determine whether or not the state is providing a safe harbor level for BpA. 

Chemical exposures above the safe harbor level trigger a Prop 65 warning, and when the state first added BpA to its list - which action led to the law suit above - a safe harbour level was provided, and that level was above the level in which most people would encounter in a product.  The Vision Council believes that a similar safe harbour level would benefit its members and other members of the optical industry.

Proposition 65 has been a California state law since 1986. Passed as the Safe Drinking Water and Toxic Enforcement Act, Prop 65, as it is commonly known, regulates the presence of certain chemical substances found in products sold in California, or present in the workplace in California. The goals of Prop 65 are to protect California's drinking water sources from contamination by those chemicals and to allow California consumers, residents and workers the information necessary to make informed choices so they can take precautions about the products they purchase or exposures they might receive to potentially hazardous chemicals.

If a business sells in California a product containing a substance or substances that are on the Prop 65 list in excess of the de minimis level for that substance, then a "clear and reasonable" warning must be provided to the public. The same is true for environmental or workplace exposures to Prop 65 substances in California.
