he California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) intends to list the chemical identified in the table below as known to the State to cause cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986. The Act, commonly known as Proposition 65, is codified in Health and Safety Code section 25249.5 et seq. This action is being taken pursuant to the Labor Code mechanism contained in Health and Safety Code section 25249.8(a).
OEHHA’s determination: Styrene meets the requirements for listing as known to the state to cause cancer for the purposes of Proposition 65.
In 2011, NTP published the Twelfth Edition of its Report on Carcinogens (NTP, 2011). In that report, NTP concluded that styrene is “‘reasonably anticipated to be a human carcinogen’ based on limited evidence of carcinogenicity from studies in humans, sufficient evidence of carcinogenicity from studies in experimental animals, and supporting data on mechanisms of carcinogenesis.” Therefore, this substance meets the requirements of Labor Code section 6382(d). The proposed listing also meets the standard set out in the recent Court of Appeal decision in the Styrene Information and Research Council v Office of Environmental Health Hazard Assessment (3rd District, Nov. 15, 2012) case because the NTP conclusion is based onsufficient evidence of carcinogenicity in experimental animals.
