Factors for IR-4 Public Interest Finding

Under the Pesticide Registration Improvement Extension Act (PRIA 3) (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: 

◦ a minor crop (≤ 300,000 acres) or a specialty crop1

, which the 2004 Specialty Crop 

Competitiveness Act defines to include:

◾ fruits;

◾ vegetables;

◾ tree nuts;

◾ dried fruits; and 

◾ nursery crops (including floriculture); or

◦ a major crop that is a representative commodity for a crop group/subgroup that is being 

submitted to establish tolerances for the minor uses/specialty crops in the crop 

group/subgroup, and where the accompanying label amendment adds at least one new 

minor use/specialty crop from that crop group to the label; or

◦ control of a niche pest on a major crop (where the most likely number of acres treated 

is ≤ 300,000 acres at the time the application is submitted); or

◦ control of a public health pest on the List of Pests of Significant Public Health 

Importance; or

◦ control of a pest identified as critical by the federal government National Plant Disease 

Recovery System (NPDRS) as called for in Homeland Security Presidential Directive 

# 9 (HSPD-9) (PDF) (5 pp, 135.5 K, About PDF); or

◦ control of a pest identified as critical by the USDA OPMP or APHIS Plant Protection 

and Quarantine (PPQ) Program Pests; or

◦ pesticide/crop combination associated with a Section 18 and there likely is insufficient 

economic incentive for the registrant to generate the data.

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

. 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.

Only 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.
