Chemicals Listed Effective March 22, 2011 as Known to the State of California to Cause Cancer - MON 4660 (dichloroacetyl-1-oxa-4-azaspiro(4,5)-decane) (CAS No. 71526-07-3), MON 13900 (furilazole) (CAS No. 121776-33-8) and pymetrozine (CAS No. 123312-89-0)

The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is adding MON 4660 (dichloroacetyl-1-oxa-4-azaspiro(4,5)-decane) (CAS No. 71526-07-3), MON 13900 (furilazole) (CAS No. 121776-33-8) and pymetrozine (CAS No. 123312-89-0) 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 65¹). The listing of the three chemicals is effective March 22, 2011.

The listing of the three chemicals is based on formal identification by an authoritative body², the U. S. Environmental Protection Agency (U.S. EPA), that the chemicals cause 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 documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for these chemicals is included in the Notice of Intent to List MON 4660 (dichloroacetyl-1-oxa-4-azaspiro(4,5)-decane), MON 13900 (furilazole), and Pymetrozine published in the January 21, 2011 issue of the California Regulatory Notice Register (Register 2011, No. 3‑Z).
