II. Summary of Petitioned-For Tolerance

In the Federal Register of April 15, 2020 (85 FR 20910) (FRL-10006-54), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 9E8794) by IR-4, IR-4 Project Headquarters, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201W, Princeton, NJ 08540. The petition requested that EPA establish tolerances in 40 CFR 180.431 for residues of the herbicide clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) in or on the raw agricultural commodities Onion, bulb, subgroup 3-07A at 0.4 parts per million (ppm); Caneberry subgroup 13-07A at 0.1 ppm; Wheatgrass, intermediate, bran at 12 ppm; Wheatgrass, intermediate, forage at 9 ppm; Wheatgrass, intermediate, germ at 12 ppm; Wheatgrass, intermediate, grain at 3 ppm; Wheatgrass, intermediate, middling at 12 ppm; Wheatgrass, intermediate, shorts at 12 ppm; Wheatgrass, intermediate, straw at 9 ppm. That document referenced a summary of the petition prepared by Corteva, the registrant, which is available in the docket, http://www.regulations.gov. No comments were received in response to the notice of filing.

III. Aggregate Risk Assessment and Determination of Safety

Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) of FFDCA defines “safe” to mean that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .”

Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for clopyralid including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with clopyralid follows.

In an effort to streamline its publications in the Federal Register, EPA is not reprinting sections that repeat what has been previously published for tolerance rulemakings of the same pesticide chemical. Where scientific information concerning a particular chemical remains unchanged, the content of those sections would not vary between tolerance rulemakings and republishing the same sections is unnecessary; EPA considers referral back to those sections as sufficient to provide an explanation of the information EPA considered in making its safety determination for the new rulemaking.

EPA has previously published a number of tolerance rulemakings for clopyralid, in which EPA concluded, based on the available information, that there is a reasonable certainty that no harm would result from aggregate exposure to clopyralid and established tolerances for residues of that chemical. EPA is incorporating previously published sections from those rulemakings as described further in this rulemaking, as they remain unchanged.

Toxicological Profile. For a discussion of the Toxicological Profile of clopyralid, see Unit III.A. of the May 23, 2018 rulemaking (83 FR 23819) (FRL-9977-13).

Toxicological Points of Departure/Levels of Concern. For a summary of the Toxicological Points of Departure/Levels of Concern used for the safety assessment, see Unit III.B. of the May 23, 2018 rulemaking.

Exposure Assessment. Much of the exposure assessment remains the same, although updates have occurred to accommodate exposures from the petitioned-for tolerances. The updates are discussed in this section; the remaining discussion of EPA's assumptions for exposure remain unchanged since the 2018 rulemaking. For a description of the rest of the EPA approach to and assumptions for the exposure assessment, see Unit III.C. of the May 23, 2018 rulemaking.

Safety Factor for Infants and Children. EPA continues to conclude that there is reliable data to support the reduction of the Food Quality Protection Act (FQPA) safety factor. See Unit III.D. of the May 23, 2018 rulemaking for a discussion of the Agency's rationale for that determination.

Aggregate Risks and Determination of Safety. EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute population adjusted dose (aPAD) and chronic PAD (cPAD). Short-, intermediate-, and chronic-term risks are evaluated by comparing the estimated aggregate food, water, and residential exposure to the appropriate PODs to ensure that an adequate margin of exposure (MOE) exists. For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure.

No acute effects were identified in the toxicological studies for clopyralid; therefore, acute risk is not expected. Chronic dietary risks are below the Agency's level of concern of 100% of the cPAD: They are 30% of the cPAD for children 1 to 2 years old, the population subgroup with the highest exposure estimate. The short-term MOE is greater than the Agency's level of concern of 100: It is 1,400 for children 1 to less than 2 years old, the population group of concern. Intermediate-term or long-term residential exposures are not expected.

Therefore, based on the risk assessments and information described above, EPA concludes there is a reasonable certainty that no harm will result to the general population, or to infants and children, from aggregate exposure to clopyralid residues. More detailed information about the Agency's analysis can be found at http://www.regulations.gov in the document titled “Clopyralid. Human Health Risk Assessment for a Proposed Use on Bulb Onion Subgroup (3-07B), Caneberry Subgroup (13-07A), Wheatgrass, and a Label Amendment for Strawberry” in docket ID number EPA-HQ-OPP-2019-0641.

IV. Other Considerations

A. Analytical Enforcement Methodology

The Pesticide Analytical Manual Volume II (PAM II) lists a method utilizing gas chromatography with electron capture detection (GC/ECD) for determination of clopyralid residues in plant commodities (Method I or Method ACR 75.6).

B. International Residue Limits

In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). No Codex MRLs have been established for clopyralid.

V. Conclusion

Therefore, tolerances are established for residues of clopyralid in or on the Caneberry subgroup 13-07A at 0.1 ppm; Onion, bulb, subgroup 3-07A at 0.4 ppm; Wheatgrass, intermediate, bran at 12 ppm; Wheatgrass, intermediate, forage at 9 ppm; Wheatgrass, intermediate, germ at 12 ppm; Wheatgrass, intermediate, grain at 3 ppm; Wheatgrass, intermediate, middling at 12 ppm; Wheatgrass, intermediate, shorts at 12 ppm; and Wheatgrass, intermediate, straw at 9 ppm.

VI. Statutory and Executive Order Reviews

This action establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled “Regulatory Planning and Review” (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), nor is it considered a regulatory action under Executive Order 13771, entitled “Reducing Regulations and Controlling Regulatory Costs” (82 FR 9339, February 3, 2017). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled “Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations” (59 FR 7629, February 16, 1994).

Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerances and modifications in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply.

This action directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or Tribal Governments, on the relationship between the National Government and the States or Tribal Governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian Tribes. Thus, the Agency has determined that Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled “Consultation and Coordination with Indian Tribal Governments” (65 FR 67249, November 9, 2000) do not apply to this action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
