II. Petition for Tolerance

In the Federal Register of September 19, 2007 (72 FR 53577) (FRL-8144-3), 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 7F7219) by E.I. DuPont de Nemours and Company, DuPont Crop Protection, P.O. Box 80038, Wilmington, DE 19880-0038. The petition requested that 40 CFR 180.439(a) be amended by establishing tolerances for residues of the herbicide, thifensulfuron methyl, methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate, in or on barley, hay at 0.7 part per million (ppm), oat, forage at 0.2 ppm; oat, hay at 2.0 ppm; wheat, forage at 1.0 ppm; and wheat, hay at 0.8 ppm. That notice referenced a summary of the petition prepared by E. I. DuPont de Nemours and Company, the registrant, which is available to the public in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

Thifensulfuron methyl currently has tolerances for grain and straw from barley, oats, and wheat. No tolerances have been established for hay and forage of these commodities because thifensulfuron methyl's registration under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), U.S.C. 136 et seq., restricts the feeding of hay and forage from treated barley, oats, and wheat to livestock. DuPont has applied to EPA to lift the feeding restriction in its FIFRA registration and this petition for hay and forage was filed in conjunction with that requested change.

Based upon review of the field trial data supporting the petition, EPA is revising the tolerance levels for pending commodities as follows: barley, hay at 0.8 ppm; oat, hay at 0.05 ppm; wheat, forage at 2.5 ppm; and wheat, hay at 0.7 ppm.

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 the petitioned-for tolerances for residues of thifensulfuron methyl, methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate, on barley, hay at 0.8 ppm; oat, forage at 0.2 ppm; oat, hay at 0.05 ppm; wheat, forage at 2.5 ppm and wheat, hay at 0.7 ppm.

EPA has previously concluded that aggregate exposure to thifensulfuron methyl on the grain and straw of barley, oats, and wheat as well as other commodities is safe. (72FR13179 (March 21, 2007)). Establishment of the requested thifensulfuron methyl tolerances on hay and forage of barley, oats, and hay will not change the exposure or risk estimates from this prior tolerance action because:

1. The requested change in FIFRA registration for thifensulfuron methyl is only for the lifting of the feeding restriction on treated barley, oats, and wheat. There are no requested changes, such as to application rates that could affect residue levels on human food items. No changes in existing tolerances are necessary.

2. The Agency has determined that there will not be finite residues of thifensulfuron methyl in animal commodities as a result of animals consuming thifensulfuron methyl-treated barley, oats or wheat.

3. Since thifensulfuron methyl is not being registered on any additional crops and the application rates to the registered crops are not increasing, there is no change in estimated drinking water estimates.

4. No residential uses are being proposed.

The toxicological profile, endpoints and current risk assessments are discussed in the final rule published in the Federal Register of March 21, 2007 (72FR13179)(FRL-8117-1) which established tolerances for residues of thifensulfuron methyl in rice, grain at 0.05 ppm; rice, straw at 0.05 ppm; sorghum, grain, forage at 0.05 ppm; sorghum, grain, grain at 0.05 ppm; and sorghum, grain, stover at 0.05 ppm. These previous risk assessments and the reasons that the current action does not change that risk assessment are discussed in the document entitled “Ingredient: Thifensulfuron Methyl Title: Label Amendments and Petition for Tolerances on Wheat Forage and Hay, Oat Forage and Hay, and Barley, Hay.” This document can be found at http://www.regulations.gov. in docket EPA-HQ-OPP-2007-0564 and is identified as document 004. Based on risk assessments and the findings presented in the Federal Register notice above, EPA concludes that there is a reasonable certainty that no harm will result to the general population and to infants and children from aggregate exposure to thifensulfuron methyl residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology ((liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS)) is 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: [phone]; e-mail address: [e-mail].

B. International Residue Limits

There are no established or proposed Codex Maximum residue limits (MRLs) for residues of thifensulfuron methyl. Canada and Mexico have established MRLs for thifensulfuron methyl on several plant commodities. However, no Canadian or Mexican MRLs for thifensulfuron methyl have been proposed or established for barley, hay; oat, forage; oat, hay; wheat, forage; or wheat, hay.

V. Conclusion

Therefore, tolerances are established for residues of thifensulfuron methyl, methyl-3-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]amino]sulfonyl]-2-thiophenecarboxylate, on barley, hay at 0.8 ppm; oat, forage at 0.2 ppm; oat, hay at 0.05 ppm; wheat, forage at 2.5 ppm and wheat, hay at 0.7 ppm.

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, 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) (Public Law 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).
