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 
7F7220) 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 180.451(a) be amended by establishing tolerances for residues of 
the herbicide, tribenuron methyl, methyl-2-[[[[(4-methoxy-6-methyl-
1,3,5-triazin-2-yl)methylamino]carbonyl]amino]sulfonyl]benzoate, in or 
on wheat, forage at 0.3 part per million (ppm); wheat, hay at 0.3 ppm; 
barley, hay at 0.3 ppm; oat, forage at 0.3 ppm; and oat, 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. One comment was 
received on the notice of filing. EPA's response to this comment is 
discussed in Unit IV.C.
    Tribenuron 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 tribenuron methyl's 
registration under the Federal Insecticide, Fungicide, and Rodenticide 
Act (``FIFRA''), 7 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 tolerances was filed 
in connection 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 0.4 ppm; oat, forage at 0.05 ppm; oat, hay at 
0.05 ppm; and wheat, hay at 0.5 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 the herbicide, tribenuron methyl, methyl-2-
[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-
yl)methylamino]carbonyl]amino]sulfonyl]benzoate on barley, hay at 0.4 
ppm; oat, forage at 0.05 ppm; oat, hay at 0.05 ppm; wheat, forage at 
0.3 ppm; and wheat, hay at 0.5 ppm.
    EPA has previously concluded that aggregate exposure to tribenuron 
methyl from tolerances for tribenuron methyl on grain and straw of 
barley, oats, and wheat as well as other commodities is safe (72 FR 
11784, March 14, 2007). Establishment of requested tribenuron methyl 
tolerances on hay and forage of oats and wheat, and on barley, hay will 
not change the exposure or risk estimates from this prior action 
because:
    1. The requested change in the FIFRA registration for tribenuron 
methyl is only for the lifting of the feeding restriction on barley, 
oats, and wheat. There are no requested changes, such as 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 tribenuron methyl in animal commodities as a result of animals 
consuming tribenuron methyl treated barley, oats, or wheat.
    3. Since tribenuron 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 14, 2007 (72 FR 11784)(FRL-8117-2) which established tolerances 
for residues of tribenuron methyl in corn, field, forage at 0.05 ppm; 
corn, field, grain at 0.05 ppm; corn, field, stover at 0.05 ppm 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, soybean seed at 0.05 ppm and sunflower, seed 
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: Tribenuron Methyl Title: Label 
Amendments and Petition for Tolerances on Barley Hay, Oat, Forage and 
Hay, and Wheat Forage and Hay.'' This document can be found at http://www.regulations.gov. in docket EPA-HQ-OPP-2007-0565 and is identified 
as document 005. 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 tribenuron 
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: <a href="/cdn-cgi/l/email-protection#10627563797465757d7564787f7463507560713e777f66"><span class="__cf_email__" data-cfemail="11637462787564747c7465797e7562517461703f767e67">[email protected]</span></a>.

B. International Residue Limits

    There are no established or proposed Codex Maximum residue limits 
(MRLs) for residues of tribenuron methyl. Canada and Mexico have 
established

[[Page 47065]]

MRLs for tribenuron methyl on several plant commodities. However, no 
Canadian or Mexican MRLs for tribenuron methyl have been proposed or 
established for barley, hay; oat, forage; oat, hay; wheat, forage; or 
wheat, hay.

C. Response to Comments

    A comment was received from a private citizen supporting the 
Agency's updating of pesticide regulations.

V. Conclusion

    Therefore, tolerances are established for residues of tribenuron 
methyl, methyl-2-[[[[(4-methoxy-6-methyl-1,3,5-triazin-2-
yl)methylamino]carbonyl]amino]sulfonyl]benzoate on barley, hay at 0.4 
ppm; oat, forage at 0.05 ppm; oat, hay at 0.05 ppm; wheat, forage at 
0.3 ppm; and wheat, hay at 0.5 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).
