II. Summary of Petitioned-For Tolerance
In the Federal Register of August 27, 2024 (89 FR 68571) (FRL-
11682-07-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 4F9117) by UPL NA, Inc., P.O. Box 12219, Research Triangle
Park, NC 27709-2219). The petition requested that 40 CFR 180.383 be
amended by establishing tolerances for residues of the herbicide
acifluorfen in or on sugar beet roots and sugar beet tops at 0.06 parts
per million (ppm). That document referenced a summary of the petition
prepared by the petitioner, which is available in the docket. 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 modifying the tolerance expression and is not establishing proposed-
for tolerance in/on sugar beet tops. EPA is also removing the
established Section 18 emergency exemption tolerances under 40 CFR
180.383(b) in or on sugar beet, root and sugar beet, leaf at 0.1 ppm.
The reasons for these changes are 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 sodium salt of acifluorfen including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with sodium salt of
acifluorfen follows.
In an effort to streamline its publications in the Federal
Register, EPA is not reprinting sections that repeat what has been
previously published for 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 sodium salt
of acifluorfen in which EPA concluded, based on the available
information, that there is a reasonable certainty that no harm would
result from aggregate exposure to sodium salt of acifluorfen and
established tolerances for residues of that chemical. EPA is
incorporating previously published sections from these rulemakings as
described further in this rulemaking, as they remain unchanged.
A. Toxicological Profile
For a discussion of the toxicological profile of sodium salt of
acifluorfen, see Unit III.A. of the final rule published in the Federal
Register of July 27, 2023 (88 FR 48383) (FRL-11130-01-OCSPP).
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 (LOCs) 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 no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(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="http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides">http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides</a>.
A summary of the toxicological endpoints and points of departure
for sodium salt of acifluorfen used for human health risk assessment
can be found in the document, ``Sodium Acifluorfen: Human Health Risk
Assessment for Proposed Uses and Tolerances on Sugar Beets'' in docket
ID number EPA-HQ-OPP-2024-0363.
C. Exposure Assessment
For a summary of the assumptions used in assessing exposure of
sodium salt of acifluorfen, see Unit III.C. of the July 27, 2023 final
rule.
1. Dietary exposure. In the July 27, 2023 final rule, EPA assessed
acute and chronic dietary (food and drinking water) exposures to sodium
salt of acifluorfen from all existing tolerances in 40 CFR 180.383,
including for sugar beet commodities which had higher time-limited
tolerance levels (0.1 ppm) than the petitioned-for tolerances (0.06
ppm) in this action. Therefore, no new dietary analyses including
drinking water were needed.
2. From non-dietary exposure. Sodium salt of acifluorfen is not
registered or proposed for any uses that would result in residential
exposure; therefore, direct exposure in residential settings are not
expected for adults and children.
3. Cumulative effects from substances with a common mechanism of
toxicity. EPA has not found sodium salt of acifluorfen to share a
common mechanism of toxicity with any other substances, and it does not
appear to produce a toxic metabolite produced by other substances. For
the purposes of this tolerance action, EPA has assumed that sodium salt
of acifluorfen does not have a common mechanism of toxicity with other
substances.
[[Page 61326]]
D. Safety Factor for Infants and Children
1. In general. FFDCA section 408(b)(2)(C) 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.
2. Prenatal and postnatal sensitivity. There is evidence of
increased susceptibility following in utero exposure to sodium salt of
acifluorfen in the Sprague Dawley rat developmental toxicity study.
However, there is low concern for developmental toxicity because the
effects are well characterized with clear no-observed-adverse-effect
level (NOAEL) and lowest-observed-adverse-effect level (LOAEL) values
and the chosen POD for risk assessment for each scenario are protective
of these effects.
3. Conclusion. EPA has determined that reliable data show that the
safety of infants and children would be adequately protected if the
FQPA SF were reduced from 10X to 1X. That decision is based on the
following findings:
i. The toxicity database for sodium salt of acifluorfen is
complete.
ii. The weight of evidence (WOE) suggests that sodium salt of
acifluorfen is not neurotoxic. This conclusion is based on the
following: (1) indications of treatment-related toxicity in the acute
neurotoxicity study (ACN) are well-characterized, and the decreased
motor activity observed could be an indication of systemic toxicity
from the bolus dose; (2) the slight effect observed in fetuses in a
developmental toxicity study with Sprague-Dawley rats (dilated brain
ventricles) were not reproduced in another developmental toxicity study
with Wistar rats nor in developmental toxicity studies with rabbits;
and (3) there was no indication of treatment-related neurotoxicity
observed in any studies for structurally-related chemicals (fomesafen,
lactofen, and oxyfluorfen), except for decreased motor activity in an
acute neurotoxicity study with fomesafen at the same dose where general
systemic toxicity (body weight loss) was observed.
iii. There is evidence that sodium salt of acifluorfen results in
increased susceptibility following exposure in utero rats in the
Sprague Dawley rat prenatal developmental study. However, there is low
concern for developmental toxicity because effects are well
characterized with clear NOAEL/LOAEL values and the chosen PODs for
risk assessment for each scenario are protective of these effects.
iv. There are no residual uncertainties identified in the exposure
database. The dietary food exposure assessments were performed based on
100% crop treated assumptions and tolerance-level residues. EPA made
conservative (protective) assumptions in the ground and surface water
modeling used to assess exposure to sodium salt of acifluorfen in
drinking water. These assessments will not underestimate the exposure
and risks posed by sodium salt of acifluorfen.
E. Aggregate Risk 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 the 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 PODs to ensure that an adequate MOE exists.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, EPA has concluded that the acute dietary
exposure to sodium salt of acifluorfen from food and drinking water
will occupy less than 1% of the aPAD for the general U.S. population
and all population subgroups. A separate point of departure was
selected for females 13-49 years old and the risk estimate was 3.9% of
the aPAD for females 13-49 years old, the population subgroups
receiving the greatest exposures. There are no residential uses of
sodium salt of acifluorfen; therefore, the acute aggregate risk is
equivalent to acute dietary risk estimates, which are below EPA's LOC
(<100% of aPAD) and not of concern.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic dietary
exposure to sodium salt of acifluorfen from food and drinking water
will occupy 87% of the cPAD for all infants less than 1 year old, the
population subgroup receiving the greatest exposure. There are no
residential uses of sodium salt of acifluorfen; therefore, the chronic
aggregate risk is equivalent to the chronic dietary risk estimate,
which is below EPA's LOC (<100% cPAD) and not of concern.
3. Short- and intermediate-term risks. Short- and intermediate-term
aggregate exposures take into account short- (1 to 30 days) and
intermediate-term (30 days to 6 months) residential exposures plus
chronic exposure to food and water (considered to be a background
exposure level). Short- and intermediate-term adverse effects were
identified; however, sodium salt of acifluorfen is not registered for
any use patterns that would result in short- or intermediate-term
residential exposures. Because there is no short- or intermediate-term
residential exposure and chronic dietary exposure has already been
assessed under the appropriately protective cPAD (which is at least as
protective as the POD used to assess short- or intermediate-term risk),
no further assessment of short- or intermediate-term risk is necessary,
and EPA relies on the chronic dietary risk assessment for evaluating
short- and intermediate-term risks for sodium salt of acifluorfen.
4. Aggregate cancer risk for U.S. population. Sodium salt of
acifluorfen is classified as, ``likely to be carcinogenic to humans at
high enough doses to cause the biochemical and histopathological
changes in livers of rodents, but unlikely to be carcinogenic at doses
below those causing these changes.'' EPA determined that the non-linear
reference dose (RfD) approach will be protective for chronic effects,
including carcinogenicity. Because the chronic risk is below EPA's
level of concern, sodium salt of acifluorfen is not expected to pose a
cancer risk to humans.
5. 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 sodium salt of acifluorfen residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methods are available to enforce the
tolerances of sodium salt of acifluorfen. The Pesticide Analytical
Manual (PAM) Volume II lists Method I, a gas chromatography-electron
capture detector (GC-ECD)
[[Page 61327]]
method for the determination of sodium salt of acifluorfen in plant
commodities. Identifications are confirmed by Method A, a gas
chromatography-mass spectrometry (GC-MS) method.
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). Codex has not established any MRLs for sodium salt
of acifluorfen.
C. Revisions to Petitioned-for Tolerances
The proposed tolerance for the commodity ``sugar beet, tops'' is
not needed since it is not considered a significant feed item. This is
based on the ``revisions of Feedstuffs in Table 1 OPPTS 860.1000 (June
2008)''. EPA is also revising the tolerance expression in 40 CFR
180.383(a) to General. Tolerances are established for residues of the
herbicide sodium acifluorfen (sodium 5-[2-chloro-4-
(trifluoromethyl)phenoxy]-2-nitrobenzoate), including its metabolites
and degradates, in or on the commodities in the table below. Compliance
with the tolerance levels specified below is to be determined by
measuring only the sum of acifluorfen acid (5-[2-chloro-4-
(trifluoromethyl)phenoxy]-2-nitrobenzoic acid), acifluorfen methyl
ester (methyl 5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoate),
acifluorfen amine, (5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-
aminobenzoic acid), and acifluorfen amine methyl ester(methyl 5-[2-
chloro-4-(trifluoromethyl)phenoxy]-2-aminobenzoate), calculated as the
stoichiometric equivalent of acifluorfen acid, in or on the commodities
based on current guidance on tolerance expressions.
Additionally, in the Federal Register of March 31, 2022 (87 FR
18717) (FRL-9657-01-OCSPP), EPA established time-limited tolerances for
residues of sodium salt of acifluorfen in or on beet, sugar, leaves and
beet, sugar, roots at 0.1 ppm, which expired on December 31, 2024. In
the Federal Register of October 25, 2024 (89 FR 85067) (FRL-12300-01-
OCSPP), EPA extended the time-limited tolerances for the above
commodities until December 31, 2027. EPA is therefore removing the
established tolerances for Section 18 emergency exemption tolerances
under 40 CFR 180.383(b) in or on sugar beet, root and sugar beet, leaf
at 0.1 ppm.
V. Conclusion
Therefore, a tolerance is established for residues of sodium salt
of acifluorfen in or on ``beet, sugar, roots'' at 0.06 ppm. In
addition, EPA is removing the established Section 18 emergency
exemption tolerances under 40 CFR 180.383(b) in or on sugar beet, root
and sugar beet, leaf at 0.1 ppm.
VI. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.
A. Executive Order 12866: Regulatory Planning and Review
This action is exempt from review under Executive Order 12866 (58
FR 51735, October 4, 1993), because it establishes or modifies a
pesticide tolerance or a tolerance exemption under FFDCA section 408 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.
B. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the PRA 44 U.S.C. 3501 et seq., because it does not contain any
information collection activities.
C. Regulatory Flexibility Act (RFA)
Since tolerance actions 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 RFA, 5 U.S.C. 601 et seq., do not apply to this
action.
D. Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate of $100 million or
more (in 1995 dollars and adjusted annually for inflation) as described
in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely
affect small governments. The action imposes no enforceable duty on any
state, local or tribal governments or on the private sector.
E. Executive Order 13132: Federalism
This action does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999), because it will
not have substantial direct effects on the states, on the relationship
between the national government and the states, or on the distribution
of power and responsibilities among the various levels of government.
F. Executive Order 13175: Consultation and Coordination with Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000), because it will
not have substantial direct effects on tribal governments, on the
relationship between the Federal government and the Indian tribes, or
on the distribution of power and responsibilities between the Federal
government and Indian tribes.
G. Executive Order 13045: Protection of Children from Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because tolerance actions like this one are exempt from
review under Executive Order 12866.
H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use
This action is not subject to Executive Order 13211 (66 FR 28355)
(May 22, 2001) because it is not a significant regulatory action under
Executive Order 12866.
I. National Technology Transfer Advancement Act (NTTAA)
This action does not involve technical standards that would require
Agency consideration under NTTAA section 12(d), 15 U.S.C. 272.
J. Congressional Review Act (CRA)
This action is subject to the CRA, 5 U.S.C. 801 et seq., and EPA
will submit a rule report to each House of the Congress and to the
Comptroller General of the United States. This action is not a ``major
rule'' as defined by 5 U.S.C. 804(2).
