## II. Summary of Petitioned-for Tolerance

                    In the                     **Federal Register**                     of March 21, 2018 (83 FR 12311) (FRL-9974-76), 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 IN-11030) by the Interregional Research Project No. 4 (IR-4), Rutgers, The State University of New Jersey, 500 College Road East, Suite 201 W, Princeton, NJ 08540. The petition requested that 40 CFR 180.560 be amended by establishing tolerances for residues of the cloquintocet-mexyl (acetic acid, [(5-chloro-8-quinolinyl)oxy]-, 1-methylhexyl ester) (CAS Reg. No. 99607-70-2) and its acid metabolite (5-chloro-8-quinlinoxyacetic acid), for use as an inert ingredient (safener) in combination with the active ingredients florasulam, fluroxypyr 1-methylhelptyl ester and pyroxsulam in or on teff, forage at 0.2 ppm; teff, grain at 0.1 ppm; teff, hay at 0.5 ppm; and teff, straw at 0.1 ppm parts per million (ppm). That document referenced a summary of the petition prepared by the Interregional Research Project No. 4 (IR-4), the petitioner, which is available in the docket,                     *http://www.regulations.gov.*                     There were no relevant comments received in response to the notice of filing.                

Based upon the fact that tolerances for cloquintocet-mexyl when used with the active ingredient pyroxsulam have previously been established under 40 CFR 180.560, the Agency's evaluation of the subject tolerance petition is limited to the use of cloquintocet-mexyl with the active ingredients florasulam and fluroxypyr 1-methylhelptyl ester on teff only.

## 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 cloquintocet-mexyl (acetic acid, [(5-chloro-8-quinolinyl)oxy]-, 1-methylhexyl ester) and its acid metabolite (5-chloro-8-quinolinoxyacetic acid) in or on teff forage, grain, hay and straw, consistent with FFDCA section 408(b)(2).

                    In the                     **Federal Register**                     of August 2, 2016 (81 FR 50630) (FRL-9947-78), EPA established tolerances for residues of cloquintocet-mexyl and its acid metabolite (5-chloro-8-quinolinoxyacetic acid) when used in pesticide formulations containing the active ingredient halauxifen-methyl, in or on barley grain, barley hay, barley straw, and wheat forage, wheat grain, wheat hay, and wheat straw. EPA is relying upon the risk assessments that supported the findings made in the August 2, 2016,                     **Federal Register**                     document in support of this action. The toxicity profile of cloquintocet-mexyl has not changed, and the previous risk assessments that supported the establishment of those tolerances remain valid.                

                    The Agency evaluated the request to establish tolerances in or on teff forage, grain, hay, and straw. Teff is prepared like other whole grains, such as rice and barley, and may also be used to make flour in a manner similar to wheat and other cereal grains. In considering likely residue levels on teff, EPA concludes that because of the similarity in application rates for pesticides containing cloquintocet-mexyl between teff and wheat, the likely decline in residue levels as teff moves through commerce, and the similarities to other small grains in terms of morphology, taxonomy and cultural practices, residue levels of cloquintocet-mexyl on teff will be similar to residue levels on wheat. The lack of teff consumption data being reported in the available food consumption data indicates a very low overall consumption of teff in the United States. When teff is consumed in the U.S., it is typically consumed in place of wheat. Using these assumptions regarding likely residue levels and consumption, EPA concludes that aggregate exposure and risk estimates resulting from cloquintocet-mexyl residues in/on teff would not be substantially different than those presented in the most recent human health risk assessment and published in the August 2, 2016 final rule. As those risk estimates were not of concern to the Agency, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to cloquintocet-mexyl residues. For a detailed discussion of the aggregate risk assessments and determination of safety for these tolerances, please refer to the August 2, 2016,                     **Federal Register**                     document and its supporting documents, available at                     *http://www.regulations.gov*                     in docket ID number EPA-HQ-OPP-2012-0843. Further information about EPA's determination that an updated risk assessment was not necessary may be found in the document, “Cloquintocet-mexyl-Human Health Risk Assessment of Tolerances without a U.S. Registration for Use on Teff” in docket ID number EPA-HQ-OPP-2016-0299.                

                    For specific information on the studies received and the nature of the adverse effects caused by cloquintocet-mexyl as well as the no-observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-level (LOAEL) from the toxicity studies, the reader is referred to the final rule published in the                     **Federal Register**                     of                           ( print page 45843)                        December 16, 2005 (70 FR 74679) (FRL-7753-4); Docket ID number EPA-HQ-OPP-2005-0234.                

## IV. Other Considerations

### A. Analytical Enforcement Methodology

Adequate enforcement methodology, chromatography with ultraviolet detection (HPLC-UV for cloquintocet-mexyl and its acid metabolite, are available to enforce the tolerance expression.

                    The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; email address:                     *residuemethods@epa.gov.*

### 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). The Codex Alimentarius is a joint United Nations Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level.

The Codex has not established a MRL for cloquintocet-mexyl (acetic acid, [(5-chloro-8-quiniolinyl)oxy]-, 1-methylhexyl ester) and its acid metabolite (5-chloro-8-quinlinoxyacetic acid) on teff.

## V. Conclusion

Therefore, tolerances are established for residues of cloquintocet-mexyl (acetic acid, [(5-chloro-8-quiniolinyl)oxy]-, 1-methylhexyl ester) and its acid metabolite (5-chloro-8-quinlinoxyacetic acid), for use as an inert ingredient (safener) when used in formulations with the active ingredients florasulam and fluroxypyr 1-methylhelptyl ester in or on teff, forage at 0.2 ppm; teff, grain at 0.1 ppm; teff, hay at 0.5 ppm; and teff, straw at 0.1 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 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 tolerance 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).
