Six Chemicals Proposed for Addition to California’s Prop 65 List
California’s Office of Environmental Health Hazard Assessment has announced its intent to add the following chemicals to the list of those known to the state to cause cancer (Proposition 65). Comments on this proposal are due no later than Aug. 12.
Prop 65 does not ban or restrict the use of listed chemicals. Instead, beginning one year after a chemical is added to the Prop 65 list businesses are required to provide a “clear and reasonable” warning before knowingly and intentionally exposing anyone to that chemical unless they can show that the anticipated exposure level will not pose a significant risk of cancer or is significantly below levels observed to cause birth defects or other reproductive harm. This warning can be given in several ways; e.g., labeling a consumer product. However, no such warning is required if exposure to a chemical occurs at or below any established safe harbor level.
