Factors for IR-4 Public Interest Finding

Under the Pesticide Registration Improvement Extension Act (PRIA 4) (FIFRA Section 33(b)(7)(E)), the Administrator shall exempt an application from the registration service fee if the Administrator determines that the application meets both of the following criteria:

(i) the application is solely associated with a tolerance petition submitted in connection with the Inter-Regional Project Number 4 (IR-4) as described in Section 2 of Public Law 89-106 (7 U.S.C. 450i(e)), and

(ii) the exemption is in the public interest.

Public Interest Presumption

An application will be presumed to be in the public interest if it is for a biopesticide or if the following criteria are met:

  • the data submitted have been developed by IR-4; and
  • the active ingredient, for which the data are developed, must have been already registered for use on a food commodity; and
  • the active ingredient/crop combination has been pre-screened by EPA prior to the Food Use Workshop, and EPA has discussed any risk concerns that might hinder registration or the establishment of tolerances with IR-4; and
  • the use is for:

For other actions that do not meet the criteria listed above, EPA will determine if a fee exemption is warranted on a case-by-case basis using a weight-of-evidence approach considering the following factors:

  • Insufficient economic incentive for the registrant to support the use for which IR-4 is generating the data.
  • Pesticide provides a new mode of action for the proposed use.
  • Pesticide plays a significant role in integrated pest management program.
  • Pesticide has characteristics that other registered alternatives do not have, including but not limited to the following:
    • pesticide provides an entirely new method of control; 
    • more effectively targets critical pest life stages;
    • avoids use of prophylactic treatments;
    • is easier on beneficial insects; or
    • allows for different timing intervals or novel placement where pests are found and is compatible with other IPM methods.
  • Insufficient efficacious alternatives.
  • Reduced risk compared to existing alternatives for the proposed crop use.

Background Information Regarding EPA Input on IR-4 Candidate List of AI/Crop Combinations

IR-4 develops residue field trial data for projects based on requests from growers, grower groups and state/federal research and extension agents. For a project to be considered, a request is made through the IR-4 website by completion of an IR-4 Minor Use Project Clearance Request Form Exit. IR-4 receives more requests for projects than there are resources, so the potential researchable projects are prioritized by various stakeholders each year at the annual IR-4 Food Use Workshop. The workshop is usually held in September.

Before the IR-4 Food Use Workshop, EPA's pesticide program receives a list of all project requests that have been submitted to IR-4. We review these candidates and identify if there are any risk concerns that would likely prevent the registration of the proposed use and the establishment of its tolerance (e.g., full risk cup for the active ingredient, cumulative risk concerns for the class of chemicals that share a common mechanism of toxicity). We provide feedback to IR-4 on any risk concerns with the proposed projects.

Following the Food Use Workshop and IR-4 determination of its list of projects, EPA encourages IR-4 to discuss with the Agency any projects that may not clearly meet the criteria described in this document before IR-4 commits any resources to these projects. While responsibility for providing an adequate public interest rationale rests with the submitter, EPA retains the final responsibility for approving a public interest finding.

These policies are being implemented in considering project proposals to be evaluated at the IR-4 Food Use Workshop. If the funding for an IR-4 project occurred before this policy was implemented in September 2013, where the project doesn’t meet the criteria listed above, the fact of such funding will be taken into serious consideration by EPA in our weight-of-evidence deliberation regarding the public interest finding.


1Only those applications for specialty crops that would require the establishment of a tolerance or tolerance exemption would meet condition (i) “application is solely associated with a tolerance petition…” and therefore could qualify for exemption from the PRIA registration fee.
