On December 2, 2021, the U.S. Environmental Protection Agency (EPA) announced it released the registration review schedule for the next four years through fiscal year (FY) 2025. While historically this schedule has been updated once each year, EPA states that going forward it will be updated on a quarterly basis.

The 2007 amendment of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires that EPA review each registered pesticide at least every 15 years. For the 726 pesticide cases that were registered before October 1, 2007, the amendment to FIFRA requires EPA to complete its review by October 1, 2022. This is significant, as it is intended to mark the end of the first 15-year registration review cycle.

Working toward that goal, EPA states that it has completed the following over the past 15 years:

• Issued more than 550 interim or final decisions;

• Completed more than 600 proposed interim decisions;

• Conducted more than 680 human health and ecological draft risk assessments (excluding endangered species assessments);

• Imposed new risk mitigation requirements for 51 percent of antimicrobial pesticides and 70 percent of conventional pesticides for which EPA issued an interim or final decision; and

• Canceled some or all uses in 120 cases.

EPA states its updated registration review schedule provides a “roadmap” for the next four years of EPA’s registration review program. EPA’s schedule includes 297 entries describing the registration review “action” (e.g., Draft Risk Assessment, Proposed Interim Decision, Interim Decision, Preliminary Work Plan, Final Work Plan) to be addressed by EPA’s different divisions (e.g., Pesticide Reevaluation Division; Antimicrobials Division, Biopesticides and Pollution Prevention Division). Throughout its review, EPA makes the information, assessments, and supporting material for each case available to the public at regulations.gov.

Significantly, but not surprisingly, EPA acknowledges that for some pesticides registered before October 1, 2007, it “anticipates that its review will extend beyond” the October 1, 2022, deadline “due to a number of challenges including delays in receiving data from registrants; the demands of responding to COVID-19; and a significant increase in recent years of resources devoted to litigation.” EPA also warns that the schedule is “subject to change based on shifting priorities and is intended to be an estimated timeline.” EPA notes further that data that are not submitted on time may affect EPA’s registration review timeline and that “several cases are not found on the schedule due to uncertainty of when necessary data will be received.”

Complying with the Endangered Species Act (ESA) is also part of the registration review process. Since 2007, EPA states that it has completed ESA assessments for certain high-priority pesticides and, in the coming years, plans to assess the effects of many more pesticides on endangered species in registration review. According to EPA, it will release its first ESA pesticides work plan in the coming months, which will outline steps EPA will take to come into compliance with the ESA in ways that are fair and transparent to the agriculture sector.
