II. Summary of Petitioned-For Tolerance

    In the Federal Register of May 8, 2020 (85 FR 27346) (FRL-10008-
38), 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 
9E8800) by IR-4, Rutgers, the State University of New Jersey, 500 
College Road East, Suite 201 W, Princeton, NJ 08540. The petition 
requested that 40 CFR 180.368(a)(2) be amended by establishing 
tolerances for residues of the herbicide S-metolachlor, S-2-chloro-N-
(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide, its R-
enantiomer, and its metabolites, determined as the derivatives, 2-(2-
ethyl-6-methylphenyl)amino-1-propanol and 4-(2-ethyl-6-methylphenyl)-2-
hydroxy-5-methyl-3-morpholinone, calculated as the stoichiometric 
equivalent of S-metolachlor, in or on Dillweed at 5 parts per million 
(ppm); Dillweed, dried leaves at 9 ppm; Dill, seed at 15 ppm; Rosemary, 
dried leaves at 2 ppm and Rosemary, fresh leaves 1.5 ppm. One comment 
was received on the notice of filing. EPA's response to this comment is 
discussed in Unit IV.C.
    In the Federal Register of March 3, 2020 (85 FR 12454) (FRL-10005-
58), 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 
9F8764) by Syngenta Crop Protection, LLC., P.O. Box 18300, Greensboro, 
NC 27419. The petition requested that 40 CFR 180.368(a)(2) be amended 
by revising the tolerances for residues of the herbicide S-metolachlor, 
S-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-
methylethyl)acetamide, its R-enantiomer, and its metabolites, 
determined as the derivatives, 2-(2-ethyl-6-methylphenyl)amino-1-
propanol and 4-(2-ethyl-6-methylphenyl)-2-hydroxy-5-methyl-3-
morpholinone, calculated as the stoichiometric equivalent of S-
metolachlor, in or on soybean seed to be 1.0 ppm and grain, aspirated 
fractions to be 2.0 ppm. That document referenced a summary of the 
petition prepared by Syngenta Crop Protection, LLC., the registrant, 
which is available in the docket, http://www.regulations.gov. There 
were no comments received in response to the notice of filing.
    Based upon review of the data supporting the petition, EPA is 
establishing several tolerances at different levels than petitioned-for 
tolerances and revised the commodity definitions for grain, aspirated 
fractions and soybean, seed. The reasons for these changes are 
explained in Unit IV.D.

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 for S-metolachlor including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with S-metolachlor 
follows.
    On March 11, 2019, EPA published in the Federal Register a final 
rule establishing tolerances for residues of S-metolachlor in or on 
several commodities based on the Agency's conclusion that aggregate 
exposure to S-metolachlor is safe for the general population, including 
infants and children. See (84 FR 8611) (FRL-9983-79). EPA is 
incorporating the following portions of that document by reference 
here, as they have not changed in the Agency's current assessment of S-
metolachlor tolerances: The toxicological profile and points of 
departure, the cancer assessment and conclusion that a nonlinear 
reference dose (RfD) approach is appropriate for assessing cancer risk, 
the conclusions about cumulative risk, and the Agency's

[[Page 40130]]

determination regarding the children's safety factor. Additionally, EPA 
is incorporating the assumptions for exposure assessment from the March 
11, 2019 final rule, which have not changed except as explained in the 
following paragraph.
    EPA's dietary (food and drinking water) exposure assessments have 
been updated to include the additional exposure from the new uses of S-
metolachlor on dill and rosemary and the revised use on soybean. EPA 
conducted an unrefined chronic dietary (food and drinking water) 
exposure and risk assessment that incorporates tolerance-level residue 
values, 100% crop treated, and EPA's 2018 default processing factors.
    The estimated drinking water concentrations (EDWCs) of S-
metolachlor and its metabolites for chronic exposures have also been 
updated; the new value used for the chronic assessment to assess the 
contribution to drinking water is 830 parts per billion (ppb), which is 
lower than the previous value of 978 ppb.
    An acute dietary endpoint (i.e., single dose endpoint) for risk 
assessment was not identified in the toxicity database for the general 
U.S. population or any other subpopulation for S-metolachlor; 
therefore, an acute dietary exposure assessment was not conducted. 
Chronic dietary risks are below the Agency's level of concern of 100% 
of the chronic population adjusted dose (cPAD); they are estimated to 
be 19% of the cPAD for all infants less than 1 year old, the group with 
the highest exposure.
    There are no proposed new residential uses for S-metolachlor, 
although commercial use in residential areas may result in the 
following short-term residential exposures that were used in the 
Agency's aggregate risk assessment: Post-application dermal exposures 
to youth (11 to less than 16 years old) from treated turf, to children 
(6 to less than 11 years old) from treated gardens, and to children (1 
to less than 2 years old) from treated turf and post-application 
incidental oral exposure to children (1 to less than 2 years old) from 
treated turf.
    For aggregate risk assessment, exposures to S-metolachlor in food 
and drinking water are combined with residential exposures for the 
relevant exposure duration period. Because acute, intermediate-term, or 
long-term residential exposures are not expected, aggregate acute and 
chronic risk is equivalent to the dietary risks, which are below EPA's 
level of concern. Moreover, based on the chronic exposure assessment, 
which accounts for potential carcinogenicity, EPA does not expect S-
metolachlor to pose a cancer risk. Short-term aggregate risk, which 
combines chronic (background) exposures with the expected short-term 
post-application exposures mentioned above, yields margins of exposure 
(MOEs) ranging from 110 to 1370, which are not of concern because they 
exceed EPA's level of concern (MOEs less than or equal to 100).
    Therefore, EPA concludes there is a reasonable certainty that no 
harm will result to the general population, or to infants and children 
from aggregate exposure to S-metolachlor residues. More detailed 
information can be found in the document entitled, ``S-Metolachlor: 
Human Health Risk Assessment for Petition for the Establishment of 
Tolerances and Registration for Use in/on Rosemary and Dill (PP#9E8800) 
and Amended Use in/on Soybean (PP# 9F8764),'' in docket IDs EPA-HQ-OPP-
2019-0652 and EPA-HQ-2020-0047.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodologies are available in the Pesticide 
Analytical Manual (PAM) Vol. II for enforcement of S-metolachlor crop 
and livestock tolerances. Pesticide regulation section 180.368, lists a 
gas chromatography with nitrogen-phosphorus detector (GC/NPD) method 
(Method I) for determining residues in/on crop commodities and a gas 
chromatography with mass selective detector (GC/MSD) method (Method II) 
for determining residues in livestock commodities. These methods 
determine residues of metolachlor and its metabolites as either CGA-
37913 or CGA-49751 following acid hydrolysis.
    The methods 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: 
[email protected].

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.
    No maximum residue limits (MRLs) for S-metolachlor have been 
established or proposed by Codex.

C. Response to Comments

    There was one comment received on the notice of filing. The comment 
stated that IR-4 is trying to get this chemical through during a 
pandemic and without public notice. The commenter also stated that this 
chemical should not be used on any food products that American's eat. 
In response, EPA notes the existing legal framework provided by section 
408 of the FFDCA 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. This comment appears 
to be directed at the underlying statute and not EPA's implementation 
of it; the comment provides no information relevant the Agency's safety 
determination.

D. Revisions to Petitioned-For Tolerances

    The Agency is establishing the tolerances for grain, aspirated 
fractions and soybean, seed at different levels than the petitioner 
requested. For grain, aspirated fractions, EPA calculated the tolerance 
level using the highest average field trial (HAFT) residues in 
combination with the median processing factor from the submitted 
soybean data. This results in a tolerance of 4 ppm rather than the 
proposed tolerance of 2.0 ppm. EPA calculated the tolerance level for 
soybean, seed using the HAFT residue values from the submitted soybean 
data in the Organization for Economic Cooperation and Development 
(OECD) MRL calculator. This results in a tolerance of 0.9 ppm rather 
than the proposed tolerance of 1.0 ppm. In addition, the commodity 
definitions were revised for grain, aspirated fractions and soybean, 
seed. Finally, a tolerance for residues in/on soybean, meal at 1.5 ppm 
has been added by the Agency based on the submitted soybean data, 
because the HAFT residues in combination with the median processing 
factor from the submitted data result in a value higher than the 
tolerance level for soybean, seed.

[[Page 40131]]

V. Conclusion

    Therefore, tolerances are established for residues of S-
metolachlor, S-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-
methylethyl)acetamide, its R-enantiomer, and its metabolites, 
determined as the derivatives, 2-(2-ethyl-6-methylphenyl)amino-1-
propanol and 4-(2-ethyl-6-methylphenyl)-2-hydroxy-5-methyl-3-
morpholinone, calculated as the stoichiometric equivalent of S-
metolachlor in or on dill, seed at 15 ppm; dillweed at 5 ppm; dillweed, 
dried leaves at 9 ppm; rosemary, dried leaves at 2 ppm; rosemary, fresh 
leaves at 1.5 ppm; and soybean, meal at 1.5 ppm. In addition, the 
Agency is increasing the tolerances for residues of S-metolachlor in or 
on grain, aspirated fractions to be 4 ppm and soybean, seed to be 0.9 
ppm.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) in 
response to petitions 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), nor is it considered a regulatory action under 
Executive Order 13771, entitled ``Reducing Regulations and Controlling 
Regulatory Costs'' (82 FR 9339, February 3, 2017). 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).
