Issuance of Safe Use Determinations and Interpretive Guidelines for Chlorothalonil Residues in Certain Foods Resulting from Pesticidal Use of the Chemical
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[1]. OEHHA received a request for a Safe Use Determination (SUD) for exposures to chlorothalonil[2] residue in certain foods resulting from pesticidal use of the chemical. The request was made by Dentons US LLP and Technology Sciences Group Inc., on behalf of Syngenta Crop Protection, LLC pursuant to Title 27 of the California Code of Regulations, section 25204(b)(3).
In accordance with the process set forth in Section 25204(f), OEHHA held a written public comment period on this request from October 27, 2017 to December 18, 2017. One public comment was received.
As provided in Sections 25204(a) and (k), OEHHA is issuing the following SUDs to Syngenta Crop Protection, LLC for chlorothalonil exposures resulting from consumption of residues in certain foods, as specified below. In addition, for nine foods or food groups OEHHA is issuing Interpretive Guidelines (IGs)[3] in response to this request. The Interpretive Guideline document is available on OEHHA’s website, http://www.oehha.ca.gov.

The essential elements and results of OEHHA’s assessments are described in the supporting documentation available at: http://oehha.ca.gov/proposition-65/proposition-65-safe-use-determinations-suds.
Based on the screening level exposure analyses described in the supporting documentation, upper-end estimates of chlorothalonil exposure were made for consumers of each of the specified foods, assuming an average rate of intake of the specified food as well as a maximum chlorothalonil residue. These upper-bound estimates of chlorothalonil exposure were compared to the NSRL for chlorothalonil of 41 µg/day. For each of the specified foods and chlorothalonil residue levels set forth in the table above, OEHHA has determined that exposure to average consumers of a particular food from consumption of chlorothalonil residues in that food is at or below the NSRL when the chlorothalonil residue does not exceed the level specified for that food, and thus a warning is not required for dietary exposure to chlorothalonil.
In addition to issuing Safe Use Determinations for a number of foods that may contain detectable amounts of chlorothalonil, OEHHA has also issued Interpretive Guidelines regarding the consumption of chlorothalonil residues in certain other foods or food forms (available at: https://oehha.ca.gov/proposition-65/interpretive-guidelines-proposition-65).
