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.
A complete, updated Proposition 65 list is published elsewhere in this issue of the California Regulatory Notice Register and is available on the OEHHA website at http://www.oehha.ca.gov/prop65.html.
