II. Summary of Petitioned-For
Tolerance
In the Federal Register of September
15, 2017 (82 FR 43352) (FRL–9965–43),
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 6E8529) by E. I.
du Pont de Nemours and Company, 974
Centre Road, Wilmington, Delaware
19805, now Corteva Agriscience after
E.I. du Pont de Nemours and Company
merged with Dow AgroScience. The
petition requested that 40 CFR 180 be
amended by establishing tolerances for
residues of the herbicide sulfometuronmethyl, in or on sugarcane, cane;
sugarcane, sugar, refined; and
sugarcane, molasses at 0.01 parts per
million (ppm). That document
referenced a summary of the petition
prepared by E. I. du Pont de Nemours
and Company, the registrant, which is
available in the docket, https://
www.regulations.gov. One comment was
received in response to the notice of
filing, and the Agency’s response can be
found in Unit IV.C.
Based upon review of the data
supporting the petition, EPA has
determined a tolerance of 0.1 sugarcane,
cane is appropriate, but that tolerances
on sugarcane, sugar, refined and
sugarcane, molasses is not needed. The
reasons for these changes are further
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
E:\FR\FM\27MRR1.SGM
27MRR1
Federal Register / Vol. 84, No. 59 / Wednesday, March 27, 2019 / Rules and Regulations
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 sulfometuronmethyl including exposure resulting
from the tolerances established by this
action. EPA’s assessment of exposures
and risks associated with sulfometuronmethyl follows.
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.
The primary toxic effect in the
toxicological database is changes in
hematological parameters and body
weight decrements. There is no
evidence that sulfometuron-methyl is a
developmental toxicant based on a
prenatal developmental study in rats
and increased susceptibility was not
commonly observed in the database for
other registered sulfonylurea herbicides
(SUs). There is no evidence of
neurotoxicity or immunotoxicity in the
toxicology databased for sulfometuronmethyl. Sulfometuron-methyl is
classified as ‘‘not likely to be
carcinogenic to humans’’ based on lack
of treatment-related increases in tumor
incidence compared to controls in the
mouse carcinogenicity study and
negative findings in the genotoxicity
toxicity studies. Sulfometuron-methyl
has low acute toxicity via oral, dermal,
and inhalation routes of exposure. It
shows minimal eye irritation and is not
a dermal irritant or sensitizer. Specific
information on the studies received and
the nature of the adverse effects caused
by sulfometuron-methyl as well as the
no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://
www.regulations.gov in document
‘‘Sulfometuron-Methyl. Human Health
Risk Assessment for a Tolerance
without a U.S. Registration for Residues
in/on Imported Sugarcane’’ at pages 18–
11417
20 in docket ID number EPA–HQ–OPP–
2017–0194.
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
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 https://
www.epa.gov/pesticides/factsheets/
riskassess.htm. A summary of the
toxicological endpoints for used for
human risk assessment is shown in
Table 1 of this unit.

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to sulfometuron-methyl, EPA
considered exposure under the
VerDate Sep<11>2014
16:40 Mar 26, 2019
Jkt 247001
petitioned-for tolerances. EPA assessed
dietary exposures from sulfometuronmethyl in food as follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
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. No such effects were
E:\FR\FM\27MRR1.SGM
27MRR1
11418
Federal Register / Vol. 84, No. 59 / Wednesday, March 27, 2019 / Rules and Regulations
identified in the toxicological studies
for sulfometuron-methyl; therefore, a
quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the United States Department of
Agriculture (USDA) 2003–2008
Nationwide Continuing Surveys of Food
Intake by Individuals (CSFII). As to
residue levels in food, EPA assumed
100% crop treated (CT) and used
tolerance-level residues for the
sugarcane commodities. The 2018
default processing factors were used (in
this case, the factors were 1 for
sugarcane commodities).
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that sulfometuron-methyl
does not pose a cancer risk to humans.
Therefore, a dietary exposure
assessment for the purpose of assessing
cancer risk is unnecessary.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue and/or PCT
information in the dietary assessment
for sulfometuron-methyl. Tolerance
level residues and/or 100% CT were
assumed for sugarcane.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for sulfometuron-methyl in drinking
water. These simulation models take
into account data on the physical,
chemical, and fate/transport
characteristics of sulfometuron-methyl.
Further information regarding EPA
drinking water models used in pesticide
exposure assessment can be found at
https://www.epa.gov/oppefed1/models/
water/index.htm.
Instead of generating chemicalspecific estimated drinking water
concentrations (EDWCs) for
sulfometuron-methyl, EPA used model
inputs (rate, soil mobility, persistence)
from all the sulfonylurea herbicides
(sulfometuron-methyl is a sulfonylurea
herbicide) to determine coarse-screen
estimates that should exceed upperbound, chemical-specific EDWCs for
any SU. The resulting coarse-screen
EDWCs generated with the Pesticide
Root Zone Model Ground Water (PRZM
GW) were higher than the surface water
estimates and were used as conservative
estimates of potential residues from
sulfometuron-methyl in drinking water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 0.492 ppm
VerDate Sep<11>2014
16:40 Mar 26, 2019
Jkt 247001
was used to assess the contribution to
drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Sulfometuron-methyl is not registered
for any specific use patterns that would
result in residential exposure.
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.’’
In 2016, EPA’s Office of Pesticide
Programs released a guidance document
entitled, Pesticide Cumulative Risk
Assessment: Framework for Screening
Analysis https://www.epa.gov/pesticidescience-and-assessing-pesticide-risks/
pesticide-cumulative-risk-assessmentframework. EPA has utilized this
framework for sulfometuron-methyl and
determined that although sulfometuronmethyl shares some chemical and/or
toxicological characteristics (e.g.,
chemical structure or apical endpoint)
with other pesticides, the toxicological
database does not support a testable
hypothesis for a common mechanism of
action. No further data are required to
determine that no common mechanism
of toxicity exists for sulfometuronmethyl and other pesticides, and no
further cumulative evaluation is
necessary for sulfometuron-methyl.
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 (10×) 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
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10×, 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 no evidence that sulfometuronmethyl is a developmental toxicant
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
based on a prenatal developmental
study in rats and increased
susceptibility was not commonly
observed in the database for other
registered SUs.
3. Conclusion. EPA has determined
that reliable data show the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1×. That decision is
based on the following findings:
i. The toxicity database for
sulfometuron-methyl is complete.
ii. There is no indication that
sulfometuron-methyl is a neurotoxic
chemical and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is no evidence that
sulfometuron-methyl results in
increased susceptibility in rabbits in a
prenatal developmental study. EPA has
concluded based on a weight-ofevidence approach that the rat
developmental and reproduction
toxicity studies are not required for
sulfometuron-methyl at this time for the
following reasons: (1) Increased
susceptibility was not commonly
observed in the SU database; and (2) the
chronic oral dog study, which is the
study used to establish points of
departure for sulfometuron-methyl,
provides similar or lower NOAEL/
LOAEL values than the rat
developmental and rat reproduction
toxicity studies across the SU database.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100% CT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to
sulfometuron-methyl in drinking water.
These assessments will not
underestimate the exposure and risks
posed by sulfometuron-methyl.
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 PAD (aPAD) and
chronic PAD (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. An acute aggregate risk
assessment takes into account acute
E:\FR\FM\27MRR1.SGM
27MRR1
Federal Register / Vol. 84, No. 59 / Wednesday, March 27, 2019 / Rules and Regulations
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, sulfometuronmethyl is not expected to pose an acute
risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to sulfometuronmethyl from food and water will utilize
9.7% of the cPAD for all infants (<1 year
old), the population group receiving the
greatest exposure. There are no
residential uses for sulfometuronmethyl; therefore, the chronic aggregate
risk assessment is equivalent to the
chronic dietary assessment. There are
no chronic dietary risks of concern.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water
(considered to be a background
exposure level). Because there are no
uses for sulfometuron-methyl that result
in residential exposures, the short-term
aggregate assessment is equivalent to the
chronic dietary assessment. There are
no chronic dietary risks of concern as
described above.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Because there are no uses for
sulfometuron-methyl that result in
residential exposures, the intermediateterm aggregate assessment is equivalent
to the chronic dietary assessment. There
are no chronic dietary risks of concern
as described above.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in the
rodent mouse carcinogenicity study and
negative findings in the mutagenicity/
genetic toxicity studies, sulfometuronmethyl is not expected to pose a cancer
risk to humans.
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
sulfometuron-methyl residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(high-performance liquid
chromatography–tandem mass
VerDate Sep<11>2014
16:40 Mar 26, 2019
Jkt 247001
spectrometry (LC–MS/MS)) 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 sulfometuronmethyl.
C. Response to Comments
One comment was submitted insisting
that no residues of sulfometuron-methyl
be permitted in food, although no
additional information was provided
that would support a conclusion that
the tolerances requested for
sulfometuron-methyl are not safe.
Although some individuals do not want
pesticides to be used on food, the
FFDCA authorizes EPA to establish
tolerances that permit certain levels of
pesticide residues in or on food when
the Agency can determine that such
residues are safe. EPA has made that
determination for the tolerances subject
to this action, and the commenter
provided no information to support a
determination that the tolerance is not
safe.
D. Revisions to Petitioned-For
Tolerances
The petitioner requested a tolerance
for residues of 0.01 ppm in/on
sugarcane, cane; sugarcane, sugar,
refined; and sugarcane, molasses. The
residue data support a tolerance on
sugarcane, cane of 0.1 ppm. This value
is also harmonized with the MRL
established in the major exporting
country, Brazil. A value of 0.01 ppm
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
11419
may create a perceived trade irritant if
the U.S. tolerance is lower than the MRL
in the major exporting country.
Tolerances for residues in/on sugarcane,
sugar, refined and sugarcane, molasses
are not needed, since residues are not
expected to concentrate in the processed
commodities.
V. Conclusion
Therefore, a tolerance is established
for residues of sulfometuron-methyl, in
or on sugarcane, cane at 0.1 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) nor is 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 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

II. Summary of Petitioned-For Tolerance
In the Federal Register of September 15, 2017 (82 FR 43352) (FRL-
9965-43), 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
6E8529) by E. I. du Pont de Nemours and Company, 974 Centre Road,
Wilmington, Delaware 19805, now Corteva Agriscience after E.I. du Pont
de Nemours and Company merged with Dow AgroScience. The petition
requested that 40 CFR 180 be amended by establishing tolerances for
residues of the herbicide sulfometuron-methyl, in or on sugarcane,
cane; sugarcane, sugar, refined; and sugarcane, molasses at 0.01 parts
per million (ppm). That document referenced a summary of the petition
prepared by E. I. du Pont de Nemours and Company, the registrant, which
is available in the docket, https://www.regulations.gov. One comment was
received in response to the notice of filing, and the Agency's response
can be found in Unit IV.C.
Based upon review of the data supporting the petition, EPA has
determined a tolerance of 0.1 sugarcane, cane is appropriate, but that
tolerances on sugarcane, sugar, refined and sugarcane, molasses is not
needed. The reasons for these changes are further 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
[[Page 11417]]
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 sulfometuron-methyl including
exposure resulting from the tolerances established by this action.
EPA's assessment of exposures and risks associated with sulfometuron-
methyl follows.
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.
The primary toxic effect in the toxicological database is changes
in hematological parameters and body weight decrements. There is no
evidence that sulfometuron-methyl is a developmental toxicant based on
a prenatal developmental study in rats and increased susceptibility was
not commonly observed in the database for other registered sulfonylurea
herbicides (SUs). There is no evidence of neurotoxicity or
immunotoxicity in the toxicology databased for sulfometuron-methyl.
Sulfometuron-methyl is classified as ``not likely to be carcinogenic to
humans'' based on lack of treatment-related increases in tumor
incidence compared to controls in the mouse carcinogenicity study and
negative findings in the genotoxicity toxicity studies. Sulfometuron-
methyl has low acute toxicity via oral, dermal, and inhalation routes
of exposure. It shows minimal eye irritation and is not a dermal
irritant or sensitizer. Specific information on the studies received
and the nature of the adverse effects caused by sulfometuron-methyl as
well as the no-observed-adverse-effect-level (NOAEL) and the lowest-
observed-adverse-effect-level (LOAEL) from the toxicity studies can be
found at https://www.regulations.gov in document ``Sulfometuron-Methyl.
Human Health Risk Assessment for a Tolerance without a U.S.
Registration for Residues in/on Imported Sugarcane'' at pages 18-20 in
docket ID number EPA-HQ-OPP-2017-0194.
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 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 https://www.epa.gov/pesticides/factsheets/riskassess.htm. A
summary of the toxicological endpoints for used for human risk
assessment is shown in Table 1 of this unit.

UFH = potential variation in sensitivity among members of the human population (intraspecies).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to sulfometuron-methyl, EPA considered exposure under the
petitioned-for tolerances. EPA assessed dietary exposures from
sulfometuron-methyl in food as follows:
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. No such effects were
[[Page 11418]]
identified in the toxicological studies for sulfometuron-methyl;
therefore, a quantitative acute dietary exposure assessment is
unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the United States
Department of Agriculture (USDA) 2003-2008 Nationwide Continuing
Surveys of Food Intake by Individuals (CSFII). As to residue levels in
food, EPA assumed 100% crop treated (CT) and used tolerance-level
residues for the sugarcane commodities. The 2018 default processing
factors were used (in this case, the factors were 1 for sugarcane
commodities).
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that sulfometuron-methyl does not pose a cancer risk to
humans. Therefore, a dietary exposure assessment for the purpose of
assessing cancer risk is unnecessary.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue and/or PCT information in the
dietary assessment for sulfometuron-methyl. Tolerance level residues
and/or 100% CT were assumed for sugarcane.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for sulfometuron-methyl in drinking water. These simulation
models take into account data on the physical, chemical, and fate/
transport characteristics of sulfometuron-methyl. Further information
regarding EPA drinking water models used in pesticide exposure
assessment can be found at https://www.epa.gov/oppefed1/models/water/index.htm.
Instead of generating chemical-specific estimated drinking water
concentrations (EDWCs) for sulfometuron-methyl, EPA used model inputs
(rate, soil mobility, persistence) from all the sulfonylurea herbicides
(sulfometuron-methyl is a sulfonylurea herbicide) to determine coarse-
screen estimates that should exceed upper-bound, chemical-specific
EDWCs for any SU. The resulting coarse-screen EDWCs generated with the
Pesticide Root Zone Model Ground Water (PRZM GW) were higher than the
surface water estimates and were used as conservative estimates of
potential residues from sulfometuron-methyl in drinking water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 0.492 ppm was used to
assess the contribution to drinking water.
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). Sulfometuron-methyl
is not registered for any specific use patterns that would result in
residential exposure.
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.''
In 2016, EPA's Office of Pesticide Programs released a guidance
document entitled, Pesticide Cumulative Risk Assessment: Framework for
Screening Analysis https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/pesticide-cumulative-risk-assessment-framework. EPA has
utilized this framework for sulfometuron-methyl and determined that
although sulfometuron-methyl shares some chemical and/or toxicological
characteristics (e.g., chemical structure or apical endpoint) with
other pesticides, the toxicological database does not support a
testable hypothesis for a common mechanism of action. No further data
are required to determine that no common mechanism of toxicity exists
for sulfometuron-methyl and other pesticides, and no further cumulative
evaluation is necessary for sulfometuron-methyl.
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 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 no evidence that
sulfometuron-methyl is a developmental toxicant based on a prenatal
developmental study in rats and increased susceptibility was not
commonly observed in the database for other registered SUs.
3. Conclusion. EPA has determined that reliable data show the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1x. That decision is based on the following
findings:
i. The toxicity database for sulfometuron-methyl is complete.
ii. There is no indication that sulfometuron-methyl is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is no evidence that sulfometuron-methyl results in
increased susceptibility in rabbits in a prenatal developmental study.
EPA has concluded based on a weight-of-evidence approach that the rat
developmental and reproduction toxicity studies are not required for
sulfometuron-methyl at this time for the following reasons: (1)
Increased susceptibility was not commonly observed in the SU database;
and (2) the chronic oral dog study, which is the study used to
establish points of departure for sulfometuron-methyl, provides similar
or lower NOAEL/LOAEL values than the rat developmental and rat
reproduction toxicity studies across the SU database.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100% CT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to sulfometuron-methyl in drinking water. These
assessments will not underestimate the exposure and risks posed by
sulfometuron-methyl.
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 PAD (aPAD) and chronic PAD (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. An acute aggregate risk assessment takes into
account acute
[[Page 11419]]
exposure estimates from dietary consumption of food and drinking water.
No adverse effect resulting from a single oral exposure was identified
and no acute dietary endpoint was selected. Therefore, sulfometuron-
methyl is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
sulfometuron-methyl from food and water will utilize 9.7% of the cPAD
for all infants (<1 year old), the population group receiving the
greatest exposure. There are no residential uses for sulfometuron-
methyl; therefore, the chronic aggregate risk assessment is equivalent
to the chronic dietary assessment. There are no chronic dietary risks
of concern.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Because there
are no uses for sulfometuron-methyl that result in residential
exposures, the short-term aggregate assessment is equivalent to the
chronic dietary assessment. There are no chronic dietary risks of
concern as described above.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). Because there are no uses for sulfometuron-methyl that result
in residential exposures, the intermediate-term aggregate assessment is
equivalent to the chronic dietary assessment. There are no chronic
dietary risks of concern as described above.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in the rodent mouse carcinogenicity study
and negative findings in the mutagenicity/genetic toxicity studies,
sulfometuron-methyl is not expected to pose a cancer risk to humans.
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 sulfometuron-methyl residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (high-performance liquid
chromatography-tandem mass spectrometry (LC-MS/MS)) 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 sulfometuron-methyl.
C. Response to Comments
One comment was submitted insisting that no residues of
sulfometuron-methyl be permitted in food, although no additional
information was provided that would support a conclusion that the
tolerances requested for sulfometuron-methyl are not safe. Although
some individuals do not want pesticides to be used on food, the FFDCA
authorizes EPA to establish tolerances that permit certain levels of
pesticide residues in or on food when the Agency can determine that
such residues are safe. EPA has made that determination for the
tolerances subject to this action, and the commenter provided no
information to support a determination that the tolerance is not safe.
D. Revisions to Petitioned-For Tolerances
The petitioner requested a tolerance for residues of 0.01 ppm in/on
sugarcane, cane; sugarcane, sugar, refined; and sugarcane, molasses.
The residue data support a tolerance on sugarcane, cane of 0.1 ppm.
This value is also harmonized with the MRL established in the major
exporting country, Brazil. A value of 0.01 ppm may create a perceived
trade irritant if the U.S. tolerance is lower than the MRL in the major
exporting country. Tolerances for residues in/on sugarcane, sugar,
refined and sugarcane, molasses are not needed, since residues are not
expected to concentrate in the processed commodities.
V. Conclusion
Therefore, a tolerance is established for residues of sulfometuron-
methyl, in or on sugarcane, cane at 0.1 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) nor is 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 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
[[Page 11420]]
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).
