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

[[Page 47074]]

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: (410) 305-2905; e-mail 
address: residuemethods@epa.gov.

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).
