Final rule.


This regulation establishes tolerances for residues of trinexapac-ethyl in or on multiple commodities and modifies existing tolerance levels and commodity definitions for trinexapac-ethyl, which are identified and discussed later in this document. EPA proposed these tolerances and noted amendments under the Federal Food, Drug, and Cosmetic Act (FFDCA) in order to correct inadvertent errors in the final rule tolerance table for trinexapac-ethyl that published in the Federal Register on March 2, 2012.


This regulation is effective October 5, 2012. Objections and requests for hearings must be received on or before December 4, 2012, and must be filed in accordance with the instructions provided in 40 CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background

In the Federal Register of July 13, 2012 (77 FR 41346) (FRL-9353-9), EPA issued a proposed rule pursuant to FFDCA section 408(e), 21 U.S.C. 346a (d)(3). The Agency-initiated rule proposed that 40 CFR 180.662 be amended by establishing tolerances for trinexapac-ethyl in or on barley, bran at 2.5 ppm; sugarcane, molasses at 2.5 ppm; and wheat, bran at 6.0 ppm. The rule also proposed amending the existing trinexapac-ethyl tolerances for wheat, forage from 1.5 to 1.0 ppm and wheat, middlings from 6.5 to 10.5 ppm, as well as changing the existing commodity definition for “hog, kidney” to “hog, meat by-products” in order to correct inadvertent errors in the final rule tolerance table for trinexapac-ethyl that was published in the Federal Register on March 2, 2012 (77 FR 12740) (FRL-9337-9). The proposed rule included a summary of the exposure assessment prepared by the Agency and explained the basis for EPA's conclusion that there is a reasonable certainty that no harm will result to the general population or to infants and children, as a result of aggregate exposure to trinexapac-ethyl residues. A comment was received in response to the proposed rule. EPA's response to that comment is discussed below in Unit III.

III. Response to Comment

An anonymous citizen objected to the presence of any pesticide residues on food. The Agency understands the commenter's concerns and recognizes that some individuals believe that pesticides should be banned completely. However, the existing legal framework provided by section 408 of the Federal Food, Drug and Cosmetic Act (FFDCA) contemplates that tolerances greater than zero may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. This citizen's comment appears to be directed at the underlying statute and not EPA's implementation of it; the citizen has made no contention that EPA has acted in violation of the statutory framework.

IV. Conclusion

Given that EPA received no meaningful comment on its proposal and based on the information, analysis, and conclusions in the July 13, 2012 proposal (77 FR 41346) (FRL-9353-9), tolerances are established, as proposed, for residues of trinexapac-ethyl, in or on barley, bran at 2.5 ppm; sugarcane, molasses at 2.5 ppm; and wheat, bran at 6.0 ppm. In addition, as proposed, the tolerance level for wheat, forage is revised from 1.5 to 1.0 ppm, the tolerance level for wheat, middlings is revised from 6.5 to 10.5 ppm and the commodity definition, “hog, kidney” is revised to “hog, meat by-products.”

V. Statutory and Executive Order Reviews

This final rule establishes tolerances under FFDCA section 408(d) on EPA's own initiative. 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 final rule has been exempted from review under Executive Order 12866, this final rule 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). This final rule 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).

Pursuant to the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency hereby certifies that these proposed tolerances will not have significant negative economic impact on a substantial number of small entities. Establishing a pesticide tolerance or an exemption from the requirement of a pesticide tolerance is, in effect, the removal of a regulatory restriction on pesticide residues in food, and thus such an action will not have any negative economic impact on any entities, including small entities.

This final rule 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 final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (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 of 1995 (NTTAA) (15 U.S.C. 272 note).

VI. 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).
