2. Summary of Petitioned-For Tolerance

   In the Federal Register of August 22, 2012 (77 FR 50661) (FRL-9358-

   9), 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 1F7937) by BASF Corporation, 26 Davis Drive, P.O. Box 13528, Research Triangle Park, NC 27709-3528. The petition requested that the tolerance in the 40 CFR 180.617 be amended by increasing the established tolerance for residues of the fungicide metconazole, 5-(4-

   chlorophenyl)-methyl-2, 2-dimethyl-1-(1H-1, 2, 4-triazol-1-ylmethyl) cyclopentanol, measured as the sum of cis- and trans- isomers, in or on corn, sweet, stover from 4.5 parts per million (ppm) to 25.0 ppm. That document 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.

   Based upon review of the data supporting the petition, EPA has modified the proposed tolerance level by increasing the tolerance for residues of corn, sweet, stover to 30 ppm. The reason for this change is explained in Unit IV.C.

3. 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

   Page 66722

   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 metconazole including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with metconazole follows.

   EPA's analysis of the impact of the proposed increase of the corn stover tolerance will have a minimal impact on exposure of livestock to metconazole and will not change the safety determination EPA made for metconazole in tolerance rulemaking published in the Federal Register of August 17, 2011 (76 FR 50898) (FRL-8882-7) and the initial establishment of the corn stover tolerance published in the Federal Register of May 7, 2009, 74 FR 21260, FRL-8408-6. In the aggregate risk assessment supporting those actions, EPA included exposure from previously established tolerances for corn and corn by-products, including corn stover (See Metconazole: Human Health Assessment for Proposed Uses on Tuberous and Corm Vegetables Subgroup 1C and Bushberry Subgroup 13-07B, EPA Docket Number EPA-HQ-OPP-2010-0621). In that risk assessment, metconazole exposure to humans due to the presence of metconazole in animal livestock feed items was calculated based on the tolerance levels in livestock commodities consumed by humans (e.g., meat and milk). Tolerance levels in livestock commodities are driven by the tolerance levels in livestock feed items, taking into account the makeup of the livestock diet. EPA's analysis of the impact of raising the corn stover tolerance shows that there will be no increase in the maximum reasonably balanced dietary burden for beef cattle, swine, or poultry but a small increase for diary cattle. There is no increase for beef cattle, swine, or poultry because sweet corn stover is only a significant feed item in dairy cattle. Although there is an increase in the estimated dietary burden of metaconazole for dairy cattle associated with the proposed increase in the corn stover tolerance, the increase is relatively small (less than 15 percent) and, based on data from a cattle feeding study with metaconazole, EPA has determined that the small increase in dietary burden to dairy cattle will not result in metaconazole residues in food commodities from dairy cattle that exceed existing tolerances. Thus, despite the increase in the corn stover tolerance, the aggregate risk assessment underlying the 2009 and 2011 metconazole rulemakings, which assumed residue levels in food commodities from dairy cattle at existing tolerances levels, remains an accurate estimate of metconazole risk.

   In the August 17, 2011 and May 7, 2009 Federal Register actions, EPA concluded that there is reasonably certainty that no harm will result to the general population and to infants and children from aggregate exposure to metconazole residues. That conclusion was based on the findings that metconazole did not pose either an acute or cancer risk and that chronic exposure to metconazole from food and water falls well below the safe exposure level for all population groups, including children 1 to 2 years old, the population group receiving the greatest exposure. Refer to the August 17, 2011 (76 FR 50898) (FRL-8882-7), Federal Register document, available at http://www.regulations.gov, for a detailed discussion of the aggregate risk assessments and determination of safety. EPA relies upon those risk assessments and the findings made in the Federal Register documents in support of this action.

4. Other Considerations

   1. Analytical Enforcement Methodology

      An adequate high performance liquid chromatography with tandem mass spectrometry (Method D0604, entitled ``The Determination of Residues of BAS 555 F and its Metabolites in Corn and Cotton Matrices Using LC/MS/

      MS''), with the German multi-residue method DFG S19 as a confirmatory method, is adequate as an enforcement method. Method D0604 determines metconazole (cis--and transisomers), 1,2,4-triazole (T), triazolyalanine (TA), and triazolylacetic acid (TAA). DFG S19 uses gas chromatography/nitrogen phosphorus detection (GC/NPD) or gas chromatography/mass spectrometric detection (GC/MS). The 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; email address: residuemethods@epa.gov.

   2. 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 metconazole on corn, sweet, stover.

   3. Revisions to Petitioned-For Tolerances

      Based on the analysis of the residue field trial data on field corn stover and using the Organization for Economic Cooperation and Development (OECD) tolerance calculation procedures, the tolerance for sweet corn stover was increased.

5. Conclusion

   Therefore, tolerances are established for residues of metconazole, 5-(4-chlorophenyl)-methyl-2, 2-dimethyl-1-(1H-1, 2, 4-triazol-1-

   ylmethyl) cyclopentanol, measured as the sum of cis- and transisomers, in or on corn, sweet, stover at 30.0 ppm.

6. Statutory and Executive Order Reviews

   This final rule 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 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

   Page 66723

   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 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).

7. 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).
