Chemicals Listed Effective March 30, 1999 as Known to the State to Cause Reproductive Toxicity: Amitraz, Disodium cyanodithiomidocarbonate, Nabam, Potassium dimethyl-dithiocarbamate, Sodium dimethyl-dithiocarbamate, and Triadimefon

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding the six chemicals named below to the list of chemicals known to the State to cause reproductive toxicity, for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65 or the Act). These chemicals are listed effective March 30, 1999. The six chemicals are listed pursuant to an administrative mechanism provided under the Act, based upon a formal identification by an authoritative body that the chemical causes reproductive toxicity. Regulations governing the listing of chemicals under the "authoritative bodies" mechanism are published in Title 22, California

The reader is directed to the Notice of Intent to List Chemicals published in the January 29, 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 have been satisfied. A complete, updated chemical list is published elsewhere in this issue of the California Regulatory Notice Register.

The six chemicals listed effective March 30, 1999, and the mechanism under which each is listed are shown below.
