Chemicals Listed as Known to the State to Cause Cancer or Reproductive Toxicity

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency has added nine chemicals to the list of chemicals known to the State to cause cancer or reproductive toxicity, for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). These chemicals are listed effective May 1, 1997.

The nine chemicals are listed pursuant to the administrative mechanisms for listing provided under the Act, based upon either (1) a formal identification by an authoritative body that the chemical is a carcinogen or a reproductive toxicant; or, (2) a formal requirement by a state or federal agency that the chemical be identified or labeled as causing cancer or reproductive toxicity. Regulations governing the listing of chemicals under the "authoritative bodies" mechanism and the "formally required to be labeled or identified" mechanism are published in Title 22, California Code of Regulations,  12306 and 12902, respectively.

The reader is directed to the Notice of Intent to List Chemicals published in the February 7, 1997 issue of the California Regulatory Notice Register for the supporting documentation which OEHHA relied upon in making its determination that the criteria for administrative listing have been satisfied.

The nine chemicals listed effective May 1, 1997, and the mechanism under which each is listed, are shown below:
