Explanation of Registration Review Schedule

As provided in the Registration Review procedural rule, EPA has developed a schedule for opening registration review dockets and will update the schedule annually. This explanation of the registration review schedule; explains how to interpret the schedule, which shows all pesticides currently subject to review and the planned schedule for opening dockets for the next three years of the program.

On This Page:


This document explains EPA's schedule for opening dockets to begin registration review for pesticide cases during the next three years (2015-2017). Previous updates have included a four-year schedule. This schedule reflects the Agency’s plan that by October 1, 2022, all pesticides that were registered as of October 1, 2007, will have been reviewed, marking the end of the first 15-year cycle. With the exception of a small number of biopesticides, the docket openings listed in this schedule represent the last group of pesticides to begin the registration review process. 

Future updates will include cases with planned decisions after October 1, 2022.

The document also provides information about docket openings accomplished between 2007 through 2014.

How to Read This Schedule

The EPA schedule for registration review is subdivided into four schedules for: (1) conventional pesticides; (2) antimicrobials; (3) biochemicals; and (4) microbials. Pesticides are organized into these lists based on their principal uses. Some have secondary uses in other categories.

The schedules are sorted in the following order.

  • The chronological order using baseline date, with the oldest first, is the primary factor.
  • Members of chemical classes that are planned for 2015 through 2017 are shown on the schedules for these years.

Each schedule has the following columns.

  1. Registration Review Case Number. The "Reg Rev Case #" column shows the Registration Review case number. We have grouped into "cases" active ingredients that are closely related in chemical structure and toxicological profile. The following is the procedure EPA used to assign case numbers.
    • Cases numbered 1 to 4999 are the same numbers as current reregistration case numbers, though active ingredients may have been added to or removed from these.  
    • 5000 to 5999 are new cases for antimicrobials that were not subject to reregistration and have not been added to an existing reregistration case. 
    • 6000 to 6999 are new cases for biochemicals and microbials that were not subject to reregistration and have not been added to an existing reregistration case.
    • 7000 to 7999 are for new conventional chemical cases that were not subject to reregistration and have not been added to an existing reregistration case.
    • 8000 to 8999 are for reregistration cases that have been divided or restructured.
  2. Registration Review Case Name. The "Registration Review Case Name" column shows the case name. A case may contain one or more active ingredients, so a case name may appear on more than one row.
  3. RED Case Number. The "RED Case #" column provides the reregistration case number for those pesticides that were subject to reregistration. A pesticide was subject to rereregistration when products containing the pesticide active ingredient were registered before November 1, 1984. A registration review case may include active ingredients that were subject to reregistration and other active ingredients that were not subject to reregistration. 
  4. PC Code. Pesticide Chemical (PC) Code is an internal EPA Office of Pesticide Programs number used to identify all active ingredients.
  5. CAS #. This is the international CAS (Chemical Abstracts Service) numbering system for chemicals.
  6. Active Ingredient Name. This is the full name of the active ingredient.
  7. Chemical Class. "Chem Class" provides codes for the major chemical classes and the soil fumigant, rodenticide, coppers, and pyrethroids, pyrethrins and synergists groups.
    The current chemical classes and groups are:
    Class Code Chemical Class Class Code Chemical Class
    BR  Bromine Compound CA Carbamate
    CC Chorine Compound CH Chloroacetanilide
    CU Coppers group DN Dinitroaniline
    FUM Fumigant group IM Imidazolinone
    IS Isothiazolone NN Neonicotinoids
    OP Organophosphate PH Phenoxy
    PPS Pyrethroids, Pyrethrins & Synergists group PY Pyridine
    QU Quaternary Compound RO Rodenticide group
    SU Sulfonylurea TO Triazole
    TR Triazine    
  8. Schedule Change. This column contains an asterisk when a case has been removed from its chronologically-based position on the list in order to group it with related cases or to achieve other program efficiencies.
  9. Baseline Date. This is the date assigned to the case to determine its chronological place in the queue for registration review.
  10. First Registered. This is the date on which EPA registered the first product containing the active ingredient.
  11. RED Status. Cases for which a RED has been completed will have the status of "Completed." For cases that had a RED completed before 1996, EPA later completed tolerance reassessment to bring the case into compliance with the Food Quality Protection Act of 1996 (FQPA). The baseline date for these cases corresponds to the date of the tolerance reassessment decision, and this column is given the status of “TRED.”
  12. RED Status Date. This column shows the RED completion date.
  13. Year Scheduled. This is the year in which EPA expects to open the docket to initiate registration review of the case. Except for chemical classes and groups listed above, dates are given only for cases scheduled for the next four years of the program.
  14. Docket Opened. This shows the docket opening date when a case has begun registration review. Each docket has a Summary Document with a Preliminary Work Plan. See: Chemical Search or the registration review dockets for more information on these cases.
  15. Final Work Plan. This shows the Final Work Plan date for cases that have these. See: Chemical Search or the registration review dockets for more information.
  16. Case Count. This is a running count of registration review cases.
  17. AI Count. This is a running count of active ingredients.

Registration Review Schedule for 2015 to 2017; Changes from Prior Schedule

The schedule has changed significantly from the prior schedule:

  • The Agency moved the schedule for related cases so that the docket will open within a few quarters of one another.
  • Triazole and rodenticides are two groups of chemicals where the schedules have been moved closer together.
  • Numerous other docket opening dates were shifted to accommodate the groupings and to move cases that may have significant data needs earlier than previously scheduled.

Communication Plan for and Comment on the Registration Review Schedule

EPA announces the availability of the updated schedule in an EPA Pesticide Program Update and posts the schedule on the Agency's website. In general, the Agency may consider issues raised by the public or the registrant when reviewing a posted schedule, to schedule a pesticide registration review, or to modify the schedule of a pesticide registration review as appropriate.
