Carbaryl (CAS No.63-25-2) Listed As Known to the State to Cause Cancer

Feb 4, 2010

The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is adding carbaryl (CAS No. 63-25-2) 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 listing of carbaryl is effective February 5, 2010.

Carbaryl (CAS No.63-25-2) 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 (the U.S. 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.

The reader is directed to the Notice of Intent to List Carbaryl (CAS No. 63-25-2) published in the November 27, 2009 issue of the California Regulatory Notice Register (Register 2009, No. 48‑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 carbaryl (CAS No. 63-25-2) 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, available at http://www.oehha.ca.gov

The table below summarizes the changes made today to the Proposition 65 list.

Chemical	CAS Number	Toxicological Endpoint	Listing Mechanism
Carbaryl	63-25-2	cancer	AB
