The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is adding metam potassium 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)1. Metam potassium is listed effective December 31, 2010.
Metam potassium (CAS No. 137-41-7) is being listed as a chemical known to the State of California to cause cancer. The listing of metam potassium is based on its 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 reader is directed to the Notice of Intent to List metam potassium published in the February 26, 2010 issue of the California Regulatory Notice Register (Register 2010, No. 9‑Z) for the documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for this chemical.
A complete, updated chemical list is published in the California Regulatory Notice Register and is available on the OEHHA website.
