II. Summary of Petitioned-For Tolerance

    In the Federal Register of July 20, 2022 (87 FR 43231) (FRL 9410-
03-OCSPP), 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 
2F8986) by Syngenta Crop Protection, LLC, P.O. Box 18300, Greensboro, 
NC 27419. The petition requested that 40 CFR 180.665 be amended by 
establishing tolerances for residues of the fungicide sedaxane, N-[2-
[1,1'-bicyclopropyl]-2-ylphenyl]-3-(difluoromethyl)-1-methyl-1H-
pyrazole-4-carboxamide, in or on Vegetable, dry bulb, crop subgroup 3-
07A and Vegetable, cucurbit, group 9 at 0.01 parts per million (ppm). 
The July 20, 2022, notice of filing referenced a summary of the 
petition prepared by Syngenta Crop Protection, LLC, the registrant, 
which is available in the docket, https://www.regulations.gov.

[[Page 37770]]

There were no comments received in response to the notice of filing.
    Based upon review of the data supporting the petition and in 
accordance with its authority under FFDCA section 408(d)(4)(A)(i), EPA 
is revising the commodity definition for ``Vegetable, dry bulb, crop 
subgroup 3-07A'' to ``Onion, bulb, subgroup 3-07A''. The reason for 
this change is explained 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 therein, 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 sedaxane, including exposure resulting from the 
tolerances established by this action. EPA's assessment of exposures 
and risks associated with sedaxane follows.
    In an effort to streamline its publications in the Federal 
Register, EPA is not reprinting sections that repeat what has been 
previously published in tolerance rulemakings for the same pesticide 
chemical. Where scientific information concerning a particular chemical 
remains unchanged, the content of those sections would not vary between 
tolerance rulemakings, and EPA considers referral back to those 
sections as sufficient to provide an explanation of the information EPA 
considered in making its safety determination for the new rulemaking.
    EPA has previously published tolerance rulemakings for sedaxane, 
most recently in the Federal Registers of December 8, 2017 (82 FR 
57867) (FRL-9970-04) and August 27, 2019 (84 FR 44703) (FRL-9998-22), 
in which EPA concluded, based on the available information, that there 
is a reasonable certainty that no harm would result from aggregate 
exposure to sedaxane and established tolerances for residues of that 
pesticide chemical. EPA is incorporating previously published sections 
from the 2017 and 2019 rulemakings as described further in this 
rulemaking, as they remain unchanged.

A. Toxicological Profile

    For a discussion of the Toxicological Profile of sedaxane, see Unit 
III.A. of the 2019 rulemaking.

B. Toxicological Points of Departure/Levels of Concern

    For a summary of the Toxicological Points of Departure/Levels of 
Concern used for the safety assessment, see Unit III.B. of the 2017 
rulemaking.

C. Exposure Assessment

    Much of the exposure assessment remains the same since the 2019 
rulemaking, although the new exposure assessment incorporates 
additional dietary exposures from the petitioned-for tolerances. The 
updates are discussed in this section; for a description of the rest of 
the EPA approach to and assumptions for the exposure assessment, see 
Unit III.C. of the 2019 rulemaking.
    Dietary exposure from food and feed uses. In evaluating dietary 
exposure to sedaxane, EPA considered exposure under the petitioned-for 
tolerances as well as all existing sedaxane tolerances in 40 CFR 
180.665. For the acute and chronic dietary exposure assessments, EPA 
used tolerance-level residues for all registered and proposed 
commodities. The acute and chronic analyses used 100 percent crop 
treated (PCT) for all commodities.
    Drinking water exposure. Drinking water exposures are not impacted 
by the proposed seed treatment uses on Onion, bulb, subgroup 3-07A and 
Vegetable, cucurbit, group 9. Since the 2019 rulemaking, EPA has 
conducted a new drinking water assessment for the registration review 
of sedaxane and subsequently updated that assessment with respect to 
seed treatment uses. Estimated drinking water concentrations (EDWCs) 
for annual potato seed treatments resulted in the highest 
concentrations for total sedaxane residues. The proposed seed treatment 
uses are not expected to result in total sedaxane residues at 
concentrations higher than the annual potato seed treatments; 
therefore, the EDWCs for annual potato seed treatments are protective. 
The groundwater EDWCs are 22.0 parts per billion (ppb) for acute 
exposures and 19.3 ppb for chronic exposures. These EDWCs were 
calculated with the Pesticide Root Zone Model for Groundwater (PRZM-
GW).
    Non-occupational exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control, indoor pest control, 
termiticides, and flea and tick control on pets). Sedaxane is not 
registered for any specific use patterns that would result in 
residential exposure, and residential exposures are not impacted by the 
proposed seed treatment uses.
    Cumulative exposure. Section 408(b)(2)(D)(v) of FFDCA requires 
that, when considering whether to establish, modify, or revoke a 
tolerance, the Agency consider ``available information'' concerning the 
cumulative effects of a particular pesticide's residues and ``other 
substances that have a common mechanism of toxicity.'' Unlike other 
pesticides for which EPA has followed a cumulative risk approach based 
on a common mechanism of toxicity, EPA has not made a common mechanism 
of toxicity finding as to sedaxane and any other substances. For the 
purposes of this action, therefore, EPA has not assumed that sedaxane 
has a common mechanism of toxicity with other substances.

D. Safety Factor for Infants and Children

    EPA continues to conclude that there is reliable data to support 
the reduction of the Food Quality Protection Act (FQPA) safety factor 
to 1X. See Unit III.D. of the 2019 rulemaking for a discussion of the 
Agency's rationale for that determination.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute population-adjusted dose (aPAD) and chronic population-adjusted 
dose (cPAD). For linear cancer risks, EPA calculates the lifetime 
probability of acquiring cancer given the estimated aggregate exposure. 
Short-, intermediate-, and chronic-term risks are evaluated by 
comparing the estimated aggregate food, water, and residential exposure 
to the appropriate points of departure (PODs) to ensure that an 
adequate margin of exposure (MOE) exists.
    Acute dietary risks are below the Agency's level of concern of 100% 
of the aPAD; they are 1.4% of the aPAD for

[[Page 37771]]

all infants (<1 year old), the population group receiving the greatest 
exposure. Chronic dietary risks are below the Agency's level of concern 
of 100% of the cPAD; they are 1.4% of the cPAD for all infants (<1 year 
old), the population group receiving the greatest exposure.
    Short- and intermediate-term aggregate exposure risks take into 
account short- and intermediate-term residential exposures, 
respectively, plus chronic exposure to food and water (considered to be 
a background exposure level). Because there are no proposed or 
registered residential uses of sedaxane, short- and intermediate-term 
risk assessments were not performed. The chronic risk assessment is 
protective for any short- and intermediate-term exposures from food and 
drinking water.
    Because the chronic risk is below the Agency's level of concern, 
EPA concludes the chronic dietary risk assessment adequately accounts 
for any potential carcinogenicity that could result from exposure to 
sedaxane.
    Therefore, based on these risk assessments, 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 
sedaxane residues. More detailed information can be found at https://www.regulations.gov in the document titled ``Sedaxane. Human Health 
Risk Assessment for a Proposed Seed Treatment Use on Bulb Onion Crop 
Subgroup 3-07A and Cucurbit Vegetables Crop Group 9'' in docket ID 
number EPA-HQ-OPP-2022-0314.

IV. Other Considerations

A. Analytical Enforcement Methodology

    For a discussion of the available analytical enforcement method, 
see Unit IV.A. of the 2019 rulemaking.

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 has not established an MRL for sedaxane in or on Onion, 
bulb, subgroup 3-07A and Vegetable, cucurbit, group 9.

C. Revisions to Petitioned-For Tolerances

    The petition requested a tolerance for ``Vegetable, dry bulb, crop 
subgroup 3-07A''. Since the time of submission, EPA has updated the 
preferred vocabulary for establishing pesticide tolerances, and the 
correct commodity definition is ``Onion, bulb, subgroup 3-07A''. The 
Agency is therefore revising the commodity definition for ``Vegetable, 
dry bulb, crop subgroup 3-07A'' to ``Onion, bulb, subgroup 3-07A''.

V. Conclusion

    Therefore, tolerances are established for residues of sedaxane, N-
[2-[1,1'-bicyclopropyl]-2-ylphenyl]-3-(difluoromethyl)-1-methyl-1H-
pyrazole-4-carboxamide, in or on Onion, bulb, subgroup 3-07A at 0.01 
ppm and Vegetable, cucurbit, group 9 at 0.01 ppm.

VI. Statutory and Executive Order Reviews

    This action 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 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 tolerances 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. 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).
