Chemical Listed Effective May 25, 2018 as Known to the State of California to Cause Cancer: TRIM® VX

Effective May 25, 2018, the Office of Environmental Health Hazard Assessment (OEHHA) is adding TRIM® VX to the list of chemicals known to the State of California to cause cancer for purposes of Proposition 65[1].  

The listing of TRIM® VX is based on formal identification by the National Toxicology Program (NTP), an authoritative body[2], 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 TRIM® VX is included in the “Notice of Intent to List: TRIM® VX” posted on OEHHA’s website and published in the January 26, 2018 issue of the California Regulatory Notice Register (Register 2018, No. 4-Z).  The publication of the notice initiated a public comment period that closed on February 26, 2018.  OEHHA received two public comments on TRIM® VX.  The comments and OEHHA’s responses are posted with the Notice of Intent to List.

A complete, updated chemical list is published in this issue of the California Regulatory Notice Register and is available on the OEHHA website at http://oehha.ca.gov/proposition-65/proposition-65-list.
