Chemical Listed September 12th, 2008 as Known to the State to Cause Cancer: Oryzalin (CAS 19044-88-3)
The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is adding oryzalin (CAS No. 19044-88-3) 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 (Health and Safety Code section 25249.5 et seq., commonly known as Proposition 65). The listing of oryzalin is effective September 12, 2008.
Oryzalin (CAS No.19044-88-3) is being listed as a chemical known to the State of California to cause cancer. The listing of this chemical is based on formal identification by an authoritative body (i.e., the U. Environmental Protection Agency (U.S. EPA)), that the chemical causes cancer. The criteria used by OEHHA for the listing of chemicals under the “authoritative bodies” mechanism can be found in Title 27, Cal. Code of Regs., section 25306 (formerly Title 22, Cal. Code of Regs., section 12306).
The reader is directed to the Notice of Intent to List Oryzalin (CAS No. 19044-88-3) published in the July 11, 2008 issue of the California Regulatory Notice Register (Register 2008, No. 28 Z) for the documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for this chemical.
OEHHA analysis of dose-response data to establish the no significant risk level (NSRL) for oryzalin (CAS No. 19044-88-3) under Proposition 65 has not yet been conducted. The priority status for the development of such analysis will be announced in a future OEHHA Proposition 65 Status Report for Safe Harbor Levels.
