II. Summary of Petitioned-For Tolerance

    In the Federal Register of March 16, 2016 (81 FR 14030) (FRL-9942-
86), 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 
5E8439) by Dow AgroSciences LLC, 9330 Zionsville Road, Indianapolis, IN 
46268. The petition requested that 40 CFR 180.638 be amended by 
establishing tolerances for residues of the herbicide pyroxsulam, N-
(5,7-dimethoxy[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)-2-methoxy-4-
(trifluoromethyl)-3-pyridinesulfonamide, in or on teff, grain at 0.01 
parts per million (ppm); teff, forage 0.06 ppm; teff, hay 0.01 ppm; and 
teff, straw 0.03 ppm. The published notice of filing (NOF) mistakenly 
listed the following incorrect tolerances for residues of pyroxsulam in 
or on the cereal crops: teff at 0.06 parts per million (ppm); teff, 
forage at 0.01 ppm; teff, grain at 0.03 ppm; teff, hay at 0.01 ppm; and 
teff, straw at 0.01 ppm. That document referenced a summary of the 
petition containing the correct tolerance amounts prepared by Dow 
AgroSciences LLC, the registrant, which is available in the docket, 
http://www.regulations.gov. Comments were received on the notice of 
filing. EPA's response to these comments is discussed in Unit IV.C.

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 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, consistent with FFDCA section 
408(b)(2).
    In the Federal Register of February 27, 2008 (73 FR 10402) (FRL-
8349-9), EPA established tolerances for residues of pyroxsulam in or on 
wheat, forage; wheat, grain; wheat, hay; and wheat, straw at the same 
levels as those requested for residues in or on corresponding teff 
commodities. Since these wheat tolerances were established in 2008, the 
toxicological profile and the endpoints for assessment have not 
changed. Moreover, as explained below, EPA has concluded that the new 
tolerances for teff commodities does not alter the previous conclusions 
about the potential aggregate exposure to pyroxsulam residues.
    Although teff residue data were not submitted with this petition, 
EPA concluded that the level of pyroxsulam residues on teff commodities 
would be the same or similar to the level of pyroxsulam residues on 
wheat commodities, based on the similarity in application rates. 
Furthermore, EPA concluded that because teff is a likely substitute for 
wheat products, there would be no additional exposure to pyroxsulam 
residues beyond what was

[[Page 30989]]

previously assessed to support the wheat tolerances. Finally, because 
there is no corresponding request for a U.S. registration allowing use 
of pyroxsulam on teff, there are no additional drinking water or 
residential exposures beyond previous assessments.
    Based on this assessment of potential exposure from use of 
pyroxsulam on teff and the findings supporting the February 27, 2008 
tolerances established for wheat commodities, 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 
pyroxsulam residues.
    For a detailed discussion of the aggregate risk assessments and 
determination of safety for the proposed tolerances, please refer to 
the February 27, 2008 Federal Register document and its supporting 
documents as well as Human Health Risk Assessments D431295, D. Dotson, 
3/25/2016 and D439358, D. Dotson, 4/21/2017 available at http://www.regulations.gov in docket ID number EPA-HQ-OPP-2006-0785.

IV. Other Considerations

A. Analytical Enforcement Methodology

    An adequate enforcement methodology, Method GRM 04.17, an Liquid 
chromatography with tandem mass spectrometry (LC/MS/MS) method, 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; email 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 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 pyroxsulam.

C. Response to Comments

    EPA received two comments to the published Notice of Filing. Both 
comments stated, in part and without any supporting information, that 
EPA should deny this petition because it is a harmful and toxic 
chemical with no benefits. The Agency recognizes that some individuals 
believe that pesticides should be banned on agricultural crops. The 
existing legal framework provided by section 408 of the Federal Food, 
Drug, and Cosmetic Act (FFDCA), however, states that tolerances may be 
set when persons seeking such tolerances or exemptions have 
demonstrated that the pesticide meets the safety standard imposed by 
that statute. EPA has assessed the effects of this chemical on human 
health and determined that aggregate exposure to it will be safe. These 
comments provide no information to support an alternative conclusion.

D. Revisions to Petitioned-For Tolerances

    EPA is revising the tolerance expression to clarify (1) that, as 
provided in FFDCA section 408(a)(3), the tolerance covers metabolites 
and degradates of pyroxsulam not specifically mentioned; and (2) that 
compliance with the specified tolerance levels is to be determined by 
measuring only the specific compounds mentioned in the tolerance 
expression.

V. Conclusion

    Therefore, tolerances are established for residues of pyroxsulam, 
N-(5,7-dimethoxy[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)-2-methoxy-4-
(trifluoromethyl)-3-pyridinesulfonamide, in or on teff, forage 0.06 
ppm; teff, grain at 0.01 ppm; teff, hay 0.01 ppm; and teff, straw at 
0.03 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes a tolerance 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 action has been 
exempted from review under Executive Order 12866, this action 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 action 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 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 action 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 action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(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 (NTTAA) (15 U.S.C. 272 note).

VII. 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.

[[Page 30990]]

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).
