Chloroprene, Cobalt sulfate heptahydrate, and Fenoxycarb Listed as Known to Cause Cancer
The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding three chemicals to the list of chemicals known to the State to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65). The chemicals are listed effective June 2, 2000 pursuant to an administrative listing mechanism provided under Proposition 65, based upon a formal identification by an authoritative body that the chemical causes cancer. Regulations governing the listing of chemicals under the "authoritative bodies" mechanism are published in Title 22, California Code of Regulations, Section 12306 (22 CCR 12306).
The reader is directed to the Notice of Intent to List Chemicals published in the March 17, 2000 issue of the California Regulatory Notice Register (Register 00, No. 11-Z) 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.
The chemicals being listed under Proposition 65 as known to cause cancer are shown below:
