Chemicals Listed Effective August 20, 1999

Chemicals Listed Effective August 20, 1999 as Known to the State of California to Cause Cancer or Reproductive Toxicity

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding the 20 chemicals named below 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 or the Act). The chemicals are listed effective August 20, 1999 pursuant to the administrative listing mechanisms provided under the Act, based upon either (1) a formal identification by an authoritative body that the chemical causes cancer or reproductive toxicity, or (2) a formal requirement by a state or federal agency that the chemical be labeled or identified as causing 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 (22 CCR), Sections 12306 and 12902, respectively.

The reader is directed to the Notice of Intent to List Chemicals published in the March 19, 1999 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 had been satisfied. A complete, updated chemical list is published elsewhere in this issue of the California Regulatory Notice Register.
