On November 15, 2024, the Department of Pesticide Regulation (DPR) published a Notice of Proposed Regulatory Action in the California Regulatory Notice Register. The Notice of Proposed Regulatory Action is also available in Spanish.
DPR proposes to adopt Title 3, California Code of Regulations (3 CCR) section 6448.5 and amend sections 6000, 6448, 6448.2, 6448.4, 6624, and 6626. In summary, the proposed action restricts the use of 1,3-dichloropropene (1,3-D) to mitigate the potential 40-year working lifetime cancer risk to occupational bystanders. The proposed action establishes buffer zone distances (distances from the edge of a treated area where certain activities are restricted) and requires DPR to include an evaluation in the 1,3-D Annual Report of whether the 1,3-D air concentration in any township exceeds the acceptable level of 0.21 part per billion and to develop appropriate measures to reduce exposures if target air concentration levels are exceeded. DPR also proposes to repeal the document “1,3-Dichloropropene Field Fumigation Requirements, Est January 1, 2024,” and adopt the document “1,3-Dichloropropene Field Fumigation Requirements, Rev. January 1, 2026,” which is incorporated by reference in existing sections 6448, 6448.2, 6624, and 6626.
