Chemicals Listed Effective May 31, 2002 as Known to the State of California to Cause Cancer: Bromate, Diuron

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding bromate and diuron 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 effective listing date for bromate and diuron is May 31, 2002.

Bromate and diuron (CAS No. 330-54-1) are listed as chemicals known to the State to cause cancer. The listing of these chemicals is based on a formal identification by an authoritative body that each of these chemicals cause cancer pursuant to an administrative listing mechanism provided under Proposition 65. 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 Notices of Intent to List for Bromate and Diuron published in the February 9, 2001, and March 29, 2002, issues of the California Regulatory Notice Register (Register 01, No. 6-Z and Register 02, No. 13-Z) for the supporting documentation which OEHHA relied upon in making its determination that the criteria for administrative listing have been satisfied for these chemicals.

A complete, updated chemical list is published elsewhere in this issue of the California Regulatory Notice Register.

In summary, the following chemicals are added to the Proposition 65 chemical list as known to the State to cause cancer:
