If you would like to sort the list by CAS number or date, please download the list as an Excel document. You can then sort the list by date, CAS number, or chemical name using MS Excel. The Excel document also includes the listing mechanism for each chemical listing and the safe harbor level, if one has been adopted. A hyperlink is provided for those chemicals for which the basis for listing documentation is available electronically. A hyperlink is provided for those safe harbor levels for which the risk assessment documentation is available electronically.
Effective February 3, 2012, the Office of Environmental Health Hazard Assessment (OEHHA) is adding kresoxim-methyl (CAS No. 143390-89-0) 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 kresoxim-methyl is based on formal identification by an authoritative body2, 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 documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for the chemical kresoxim-methyl is included in the Notice of Intent to List Kresoxim-Methyl and Tetraconazole published in the December 2, 2011 issue of the California Regulatory Notice Register (Register 2011, No. 48‑Z).
A complete, updated chemical list is published in this issue of the California Regulatory Notice Register and is available on the OEHHA website at www.oehha.ca.gov.
In summary, the following chemical is being listed under Proposition 65 as known to the State to cause cancer:
