Cloquintocet-mexyl; Pesticide Tolerances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation amends the established tolerance expression 
for residues of cloquintocet-mexyl and its acid metabolite on wheat 
forage, wheat grain, wheat hay, and wheat straw to cover residues in or 
on these commodities when cloquintocet-mexyl is used as an inert 
ingredient (safener) in pesticide formulations containing the active 
ingredient, dicamba. BASF Corporation requested this tolerance 
amendment under the Federal Food, Drug, and Cosmetic Act (FFDCA).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of March 29, 2011 (76 FR 17374) (FRL-8867-
4), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 
0E7781) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 
27709. The petition requested that 40 CFR 180.560 be amended by 
expanding the tolerances therein to cover residues of the inert 
ingredient (herbicide safener), 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-quinolinoxyacetic acid) on 
wheat forage, wheat grain, wheat hay, and wheat straw when used in 
formulation with the active ingredient, dicamba. No numerical change to 
the tolerances for the specific wheat commodities was sought. That 
notice referenced a summary of the petition prepared by BASF 
Corporation, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments 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 section 408(b)(2)(D) of FFDCA, and the factors 
specified in section 408(b)(2)(D) of FFDCA, 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 
including exposure resulting from the amended tolerances established by 
this action. EPA's assessment of exposures and risks associated with 
cloquintocet-mexyl follows.
    In the Federal Register of March 31, 2010 (75 FR 16017) (FRL-8816-
3), EPA issued a final rule that amended 40 CFR 180.560 by adding a 
reference to the active ingredient, flucarbazone-sodium (wheat only). 
When the Agency conducted the risk assessments supporting this 
tolerance action, it assumed that 100% of wheat crops were treated with 
cloquintocet-mexyl and that residues were present on all wheat 
commodities at the tolerance levels. With these assumptions, exposure 
to cloquintocet-mexyl did not exceed 1% of the acute Population 
adjusted dose or chronic Population adjusted dose for the

[[Page 38035]]

most exposed population groups. Since this current action to amend the 
tolerance expression of cloquintocet-mexyl does not involve a change in 
the tolerance levels for wheat commodities, the toxicity database has 
not changed, and exposure has already been assessed based on the 
conservative assumption that all wheat is treated with cloquintocet-
mexyl and contains tolerance-level residues, EPA concludes that the 
last risk assessment, described in its entirety in the March 31, 2010 
final rule, is still applicable.
    Therefore, based on the risk assessment discussed in the final rule 
published in the Federal Register of March 31, 2010, 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 and its acid metabolite (5-chloro-8-
quinolinoxyacetic acid).

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology is available to enforce the 
tolerance expression. The two enforcement methods are the High 
Performance Liquid Chromatography with Ultraviolet Detection (HPLC/UV) 
method REM 138.01 for determination of cloquintocet-mexyl (parent) and 
the HPLC/UV Method REM 138.10 for determination of its acid metabolite. 
These methods may be requested from: Chief, Analytical Chemistry 
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 
20755-5350; telephone number: (410) 305-2905; e-mail 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 U.N. 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.

V. Conclusion

    Therefore, the previously established tolerance expression for 
residues of cloquintocet-mexyl and its acid metabolite on wheat forage, 
wheat grain, wheat hay, and wheat straw is amended as set forth in the 
regulatory text.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under section 408(d) of 
FFDCA 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 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).
    Since tolerances and exemptions that are established on the basis 
of a petition under section 408(d) of FFDCA, 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 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 section 408(n)(4) of FFDCA. 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) (Pub. L. 104-4).
    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), Public Law 104-113, section 12(d) (15 U.S.C. 272 
note).

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report to each House of the Congress and to 
the Comptroller General of the United States. 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 this final rule in the Federal 
Register. This final rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
