The Office of Environmental Health Hazard Assessment (OEHHA) within the California Environmental Protection Agency is adding S,S,S-tributyl phosphorotrithioate (Tribufos, DEF) (CAS No. 78-48-8) 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 ). The listing of S,S,S-tributyl phosphorotrithioate (Tribufos, DEF) is effective February 25, 2011.
S,S,S-Tributyl phosphorotrithioate (Tribufos, DEF) (CAS No. 78-48-8) is being listed as a chemical known to the State of California to cause cancer. The listing of S,S,S-tributyl phosphorotrithioate is based on formal identification by an authoritative body , 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 S,S,S-tributyl phosphorotrithiate (Tribufos, DEF) published in the August 13, 2010 issue of the California Regulatory Notice Register (Register 2010, No. 33‑Z) for the documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for this chemical..
