The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (commonly known as Proposition 65, codified at Health and Safety Code section 25249.5 et seq.).  OEHHA has received a request for a Safe Use Determination (SUD) for chlorothalonil in certain foods resulting from pesticidal use of the chemical.  The request is made by Syngenta Crop Protection, LLC pursuant to Title 27 of the California Code of Regulations, section 25204(b)(3).

This SUD request is limited to exposures to chlorothalonil from consumption of certain foods.  Exposure to other listed substances, if any, which may be present in these foods will not be reviewed by OEHHA in the context of this request.
