The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) issued requests for relevant information in the California Regulatory Notice Register as to whether clodinafop-propargyl (CAS No. 105512-06-9) and metofluthrin (CAS No. 240494-70-6) meet the criteria for listing as causing cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986 (Register 2009, No. 46-Z; and Register 2008, No. 49-Z, respectively). OEHHA issued the information request for metofluthrin on December 5, 2008, and the request for clodinafop-propargyl on November 13, 2009.
The U.S. Environmental Protection Agency (U.S. EPA) has changed its classification for these chemicals. Therefore, they do not meet the sufficiency criteria specified in Title 27, California Code of Regulations, section 25306(d). In view of this change in the cancer classifications of the chemicals by the U.S. EPA, OEHHA will not proceed with the proposed listing of these chemicals as known to cause cancer via the authoritative bodies mechanism at this time.
