EPA Extends Comment Period on Proposed Guidance for Pesticide Registrants to Improve Efficiencies on Notifications and Minor Amendments Submitted to the Agency

U.S. Environmental Protection Agency (EPA) is extending the public comment period to give commenters more time to provide meaningful input on the 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.  

EPA released the proposed updates in December 2025 with a comment period closing on February 19, 2026. Upon publication of the Federal Register notice extending the comment period, comments can be submitted to docket docket ID EPA-HQ-OPP-2025-2863 on www.regulations.gov for an additional 30 days. Comments must be received on or before March 23, 2026.
