OEHHA Adds PCBTF to Prop 65 List


Prop 65

On June 28, California’s Office of Environmental Health Hazard Assessment (OEHHA) added para-chlorobenzotrifluoride (PCBTF) as known to the state to cause cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986, or Proposition 65 (Prop 65). PCBTF is used in coatings and inks.

Under Prop 65, individuals must provide warnings prior to exposure to a chemical identified by the State of California to cause cancer or reproductive harm. The duty to warn applies to most individuals causing an exposure, including product manufacturers, employers and individuals causing exposures in an affected area. Prop 65 requires the State of California maintain a list of chemicals that are known to the State to cause cancer, birth defects or other reproductive harm, or both. The list includes over 900 chemicals since it was published in 1987. The state can add chemicals to the Prop 65 list using four mechanisms: 1) the State’s qualified expert mechanism; 2) formally required to label mechanism; 3) labor code listing mechanism; and 4) authoritative body mechanism.

OEHHA’s listing followed a report on PCTBF issued in June 2018 by the National Institutes of Health’s (NIH) National Toxicology Program (NTP). Generally, OEHHA recognizes the findings of a competent body (NTP) to list a chemical.
