PRN 98-10: Notifications, Non-Notifications and Minor Formulation Amendments
On December 31, 2025, EPA released for public comment proposed updates to Pesticide Registration Notice (PRN) 98-10, “Notifications, Non-notifications and Minor Formulation Amendments.” The new draft would provide updated guidance to registrants submitting minor modifications to a registration that do not require extensive EPA review. These modifications do not have any substantive impact on the use or safety of a pesticide. The proposed changes will not impact any procedures for the review of information related to environmental or human health.

On September 15, 2021, the Agency announced the termination of the May 11, 2020, temporary amendment effective September 15, 2022, and that any changes made using the temporary amendment must be made permanent by Sept. 15, 2022. The Agency requires additional time to complete the review and approval of the notifications and amendments to make these changes permanent and is therefore extending the deadline to March 15, 2023.
