II. Summary of Petitioned-For Tolerance
In the Federal Register of September 12, 2023 (88 FR 62499) (FRL-
10579-07-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 3E9048) by Syngenta Crop Protection, LLC, P.O. Box 18300,
Greensboro, NC 27419. The petition requested that 40 CFR part 180 be
amended by establishing tolerances for residues of the fungicide
mefenoxam, in or on palm oil at 0.02 parts per million (ppm). That
document referenced a summary of the petition
[[Page 87510]]
prepared by Syngenta Crop Protection, LLC., the registrant, which is
available in the docket, <a href="https://www.regulations.gov">https://www.regulations.gov</a>. 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 for mefenoxam including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with mefenoxam follows.
In an effort to streamline its publications in the Federal
Register, EPA is not reprinting sections of the rule 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 a tolerance rulemaking for mefenoxam
in which EPA concluded, based on the available information, that there
is a reasonable certainty that no harm would result from aggregate
exposure to mefenoxam and established tolerances for residues of that
chemical. EPA is incorporating previously published sections from that
rulemaking as described further in this rule, as they remain unchanged.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children.
Mefenoxam (metalaxyl-m) is a systemic phenylamine fungicide which
inhibits protein synthesis in fungi. Mefenoxam is an R-isomer enriched
formulation. Metalaxyl is the racemic R/S isomer formulation. The
Agency compared the available chemistry and toxicity data for mefenoxam
and metalaxyl and concluded that metalaxyl data may be used in support
of mefenoxam regulatory actions because the two chemicals have similar
toxicity.
Specific information on the studies received and the nature of the
adverse effects caused by mefenoxam as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies are discussed in Unit III.A. of the
final rule published in the Federal Register of December 21, 2018 (83
FR 65541) (FRL-9985-52).
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which the NOAEL and the LOAEL). Uncertainty/
safety factors are used in conjunction with the POD to calculate a safe
exposure level--generally referred to as a population-adjusted dose
(PAD) or a reference dose (RfD)--and a safe margin of exposure (MOE).
For non-threshold risks, the Agency assumes that any amount of exposure
will lead to some degree of risk. Thus, the Agency estimates risk in
terms of the probability of an occurrence of the adverse effect
expected in a lifetime. For more information on the general principles
EPA uses in risk characterization and a complete description of the
risk assessment process, see <a href="https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides">https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides</a>.
A summary of the toxicological endpoints for mefenoxam used for
human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of December 21, 2018 (83 FR 65541)
(FRL-9985-52).
C. Exposure Assessment
Much of the exposure assessment remains the same although updates
have occurred to accommodate exposures from petitioned-for tolerances.
These updates are discussed in this section; for a description of the
rest of the EPA approach to and assumptions for the exposure
assessment, please reference Unit III.C. of the December 2018,
rulemaking.
1. Dietary exposure from food and feed uses. EPA's dietary exposure
assessments have been updated to include the additional exposure from
the petitioned-for tolerances of mefenoxam on the crops requested in
this action. In evaluating dietary exposure to mefenoxam, EPA
considered exposure under the petitioned-for tolerances as well as all
existing mefenoxam and metalaxyl tolerances in 40 CFR 180.546 and
180.408, respectively.
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure. The acute dietary assessment
is based on tolerance levels adjusted to account for all of the
residues of concern and assumes 100 percent crop treated (PCT). The
assessment was conducted using the Dietary Exposure Evaluation Model
software with the Food Commodity Intake Database (DEEM-FCID) Version
4.02, EPA with 2005-2010 food consumption information from the United
States Department of Agriculture's (USDA's) National Health and
Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA).
Empirical processing factors were included where available. Otherwise,
DEEM-FCID default processing factors were used.
ii. Chronic exposure. There is no increase in hazard from repeat
exposures to mefenoxam. Therefore, a chronic dietary POD was not
selected. The acute endpoint and acute dietary
[[Page 87511]]
exposure assessment are protective of potential effects from chronic
duration dietary exposures.
iii. Cancer. EPA has concluded that mefenoxam does not pose a
cancer risk to humans based on no evidence of carcinogenicity observed
in the relevant studies. Therefore, a dietary exposure assessment for
the purpose of assessing cancer risk is unnecessary.
2. Dietary exposure from drinking water. Drinking water exposure
modeling for mefenoxam is not necessary because exposure estimates for
metalaxyl are expected to exceed those for mefenoxam and are therefore
protective. Maximum annual application rates for metalaxyl, up to 12.3
lb ai/A, were modeled. These rates are approximately twice those of
mefenoxam. The maximum estimated drinking water concentrations (EDWCs)
based on metalaxyl are 350 [mu]g/L for acute exposure (which is based
on surface water sources) and 135 [micro]g/L for chronic exposure
(which is based on groundwater sources).
3. From non-dietary 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). There are no
residential uses for mefenoxam being proposed as part of this action or
that have been added since the most recent risk assessment that would
impact the residential (non-occupational) or residential post-
application exposure and risk estimates found in the most recent risk
assessment of mefenoxam; therefore, EPA relied on the previously
assessed residential exposure for assessing aggregate risk.
4. Cumulative effects from substances with a common mechanism of
toxicity. 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 mefenoxam and metalaxyl
with any other substances and mefenoxam and metalaxyl do not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this action, therefore, EPA has not assumed that mefenoxam
and metalaxyl have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's website at <a href="https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides">https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides</a>.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act (FQPA) Safety Factor (SF). In applying this provision,
EPA either retains the default value of 10X, or uses a different
additional safety factor when reliable data available to EPA support
the choice of a different factor.
EPA continues to conclude that there are reliable data to support
the reduction of the (FQPA) (SF) to 1X. See Unit III.D. of the December
2018, 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 dietary exposure estimates to the acute
PAD (aPAD) and chronic PAD (cPAD). Short-, intermediate-, and chronic-
term aggregate risks are evaluated by comparing the estimated total
food, water, and residential exposure to the appropriate PODs to ensure
that an adequate MOE exists.
1. Acute risk. The acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. Using the exposure assumptions discussed in this unit
for acute exposure, the acute dietary exposure from food and water is
27% of the acute population-adjusted dose (aPAD) for the general U.S.
population, and 55% of the aPAD for the highest exposed population
group, all infants. Because there are no acute residential exposures
from mefenoxam, the acute aggregate exposure and risk is equal to the
acute dietary exposure and risk. As these levels are below the Agency's
level of concern (LOC) of 100% of the aPAD, the Agency concludes that
aggregate exposure to mefenoxam will not pose an acute risk.
2. Chronic risk. No hazard endpoint was selected for chronic
dietary exposure for mefenoxam; therefore, a chronic dietary analysis
was not warranted. However, chronic dietary exposure was estimated for
inclusion in the short-term aggregate analysis.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus average chronic exposure
to food and water (considered to be a background exposure level).
Mefenoxam is currently registered for uses that could result in short-
term residential exposure, and the Agency has determined that it is
appropriate to aggregate chronic exposure through food and water with
short-term residential exposures to mefenoxam.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 270 for children
1 to 2 years old, the most highly exposed group. Because EPA's level of
concern for mefenoxam is 100, which means any MOE below 100 may
indicate risks of concern, this MOE is not of concern.
4. Intermediate-term risk. There are no intermediate-term
residential exposures for mefenoxam, and therefore an intermediate-term
aggregate exposure assessment was not warranted.
5. Aggregate cancer risk for U.S. population. Mefenoxam is
classified as ``not likely to be carcinogenic to humans'', therefore,
EPA concludes that exposure to mefenoxam will not pose an aggregate
cancer risk.
6. Determination of safety. 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 mefenoxam residues.
More detailed information on this action can be found in the
document titled ``Metalaxyl-M (Mefenoxam)''. Human Health Risk
Assessment for Establishment of a Tolerance without U.S. Registration

IV. Other Considerations
A. Analytical Enforcement Methodology
For a discussion of the available enforcement analytical methods,
see Unit IV.A. of the December 21, 2018, rulemaking.
[[Page 87512]]
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. Tolerances/maximum
residue limits (MRLs) to support uses of mefenoxam in Canada are
established for residues of metalaxyl, including metabolites that can
be converted to the 2,6-DMA moiety, each expressed as metalaxyl
equivalents. However, no MRLs are established for palm fruit in Codex
and Canada; thus, harmonization is not an issue for this commodity.
C. Response to Comments
Three comments were received in response to the notice of filing.
One comment was received from an anonymous commenter applauding the
government's process to petition for new uses. The other two comments
were criticizing chemicals that are not relevant to this action.
V. Conclusion
Therefore, tolerances are established for residues of mefenoxam
[methyl N-(2,6-dimethylphenyl)-N-(methoxyacetyl)-D-alaninate], in or on
palm, oil at 0.02 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 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. 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).
