Registration Review Schedules

Through the Pesticide Registration Review program, EPA reviews all registered pesticides at least every 15 years, as mandated by the Federal Insecticide, Fungicide, and Rodenticide Act.

EPA always strives to base its decisions on the best available sound science. However, science is constantly evolving, and new scientific information can come to light at any time and change our understanding of potential risks from pesticides. The review of new data could potentially prolong the risk assessment and decision-making process and change this schedule.

The schedule below shows the status of pesticides undergoing registration review. This schedule is subject to change based on shifting priorities and is intended to be a rough timeline. We will update the schedule regularly to reflect any timeline changes and to include anticipated deliverables for later dates.

Explanation of List

EPA commits to an open and transparent process by accepting public comments at most stages of the process. These are collected in each chemical’s docket at www.regulations.gov and all comments submitted will be accounted for in the Agency’s regulatory decisions for each chemical.

The schedule is also categorized by the fiscal year's (FY) quarters. Please note the following timeframes:
  • Quarter 1 (Q1): October - December
  • Quarter 2 (Q2): January - March
  • Quarter 3 (Q3): April - June
  • Quarter 4 (Q4): July - September
