California proposes clarifying changes to Prop 65 guidelines

California’s Office of Environmental Health Hazard Assessment (OEHHA) has proposed further amendments to guidelines for “clear and reasonable” consumer product warnings, as mandated under Proposition 65. OEHHA implements the law, which requires businesses to provide the warnings of potential exposure to chemicals listed as a carcinogen or reproductive toxicants. The warning guidelines, specified in Article 6 of Title 27 in California’s Code of Regulations, were adopted in August 2016 and amended in November 2017. After receiving input from stakeholders, California determined that further clarifying changes were needed. The amendments will not impose any new costs because OEHHA says they “simply clarify the responsibility of intermediate parties in the chain of commerce to pass along a warning for consumer products”. Affected businesses are likely to benefit from the proposed regulatory action, it says, which also further clarify the definition of “actual knowledge”. Public comments on the proposal will be accepted until 31 December. Further Information is available at:
