II. Summary of Petitioned-For Tolerance
In the Federal Register of September 22, 2021 (86 FR 52624) (FRL-
8792-03-OCSPP), EPA issued a document pursuant to FFDCA section
408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide
petition (PP 1E8926) by IR-4, North Carolina State University, 1730
Varsity Drive, Venture IV, Suite 210, Raleigh, NC 27606. The petition
requested that 40 CFR 180.478 be amended by establishing tolerances for
residues of the herbicide rimsulfuron (N-[[(4,6-dimethoxy-2-
pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2-pyridinesulfonamide),
in or on pomegranate at 0.01 parts per million (ppm) and tropical and
subtropical, small fruit, edible peel, subgroup 23A at 0.01 ppm. There
were no comments received in response to the notice of filing.
III. Aggregate Risk Assessment and Determination of Safety
FFDCA section 408(b)(2)(A)(i) 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.'' FFDCA section
408(b)(2)(A)(ii) 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. FFDCA section 408(b)(2)(C)
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 rimsulfuron including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with rimsulfuron 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 rulemaking of the same pesticide
chemical. Where scientific information concerning a particular chemical
remains unchanged, the content of those sections would not vary between
tolerance rulemaking and republishing the same sections is unnecessary.
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 rimsulfuron
in which EPA concluded, based on the available information, that there
is a reasonable certainty that no harm would result from aggregate
exposure to rimsulfuron and established tolerances for residues of that
chemical. EPA is incorporating previously published sections from this
rulemaking as described further in this rulemaking, as they remain
unchanged.
Toxicological profile. For a discussion of the Toxicological
Profile of rimsulfuron, see Unit III.A of the February 12, 2018, final
rulemaking (83 FR 5942) (FRL-9972-36).
Points of departure/Levels of concern. A summary of the
toxicological endpoints for rimsulfuron used for human risk assessment
is discussed in Unit III.B of the February 12, 2018, final rulemaking.
Exposure assessment. Much of the exposure assessment remains the
same although updates have occurred to accommodate the exposures from
the 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 February 12, 2018, final rulemaking.
EPA's dietary exposure assessments have been updated to include the
additional exposures from the new uses of rimsulfuron on pomegranate
and tropical and subtropical, small fruit, edible peel, subgroup 23A.
An unrefined chronic dietary (food and drinking water) exposure and
risk assessment was conducted using the Dietary Exposure Evaluation
Model software with the Food Commodity Intake Database (DEEM-FCID)
Version 4.02. This software incorporates 2005-2010 consumption data
from the U.S. Department of Agriculture's (USDA's) National Health and
Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA).
The chronic assessment used tolerance level residues for all crops and
assumed that 100% of the crops were treated with rimsulfuron. The
Agency's default processing factors were used where available. An acute
dietary exposure assessment was not conducted since there was no
adverse effect observed for a single dose of rimsulfuron.
Dietary exposure from drinking water. The new uses do not result in
an increase in the estimated residue levels in drinking water, so EPA
used the same estimated drinking water concentrations in the chronic
dietary assessment as identified in Unit III.C of the February 12,
2018, rulemaking.
From non-dietary exposure. There are no proposed residential uses
at this time; however, there are existing residential uses on turf that
have been previously assessed using current data and assumptions. For
the residential assessment of the turf uses, EPA did not conduct a
quantitative residential handler risk assessment. The end use label
requires handlers to wear specific clothing (long-sleeve shirt and long
pants) and chemical-resistant gloves, so EPA assumed the product is not
for homeowner use. There is the potential for post-application dermal
exposures; however, a residential post-application dermal exposure
assessment was not conducted because no dermal hazard was identified in
the rimsulfuron database. The quantifiable post-application residential
risk estimates reflect incidental oral exposure to children 1 to less
than 2 years old from hand-to-mouth exposure to turf treated with
rimsulfuron. The margin of exposure (MOE) is 26,000, which is greater
than the level of concern of 100 and is not of concern.
[[Page 4734]]
Cumulative effects from substances with 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 <a href="https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/pesticide-cumulative-risk-assessment-framework">https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/pesticide-cumulative-risk-assessment-framework</a>. The agency has utilized this framework for rimsulfuron and
determined that although rimsulfuron 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 rimsulfuron and other pesticides and no further
cumulative evaluation is necessary for rimsulfuron.
Safety factor for infants and children. EPA continues to conclude
that there are reliable data to support the reduction of the Food
Quality Protection Act (FQPA) safety factor (SF) from 10X to 1X for all
risk scenarios. See Unit III.D. of the February 12, 2018, final
rulemaking for a discussion of the Agency's rationale for that
determination.
Aggregate risks and Determination of safety. EPA determines whether
acute and chronic dietary pesticide exposures are safe by comparing
aggregate exposure estimates to the acute population adjusted dose
(aPAD) and the chronic population adjusted dose (cPAD). Short-,
intermediate-, and chronic-term risks are evaluated by comparing the
estimated aggregate food, water, and residential exposure to the
appropriate points of departure to ensure that an adequate MOE exists.
For linear cancer risks, EPA calculates the lifetime probability of
acquiring cancer given the estimated aggregate exposure.
An acute dietary exposure assessment was not conducted since there
was no adverse effect observed for a single dose of rimsulfuron.
Chronic dietary risks are below the Agency's level of concern of 100%
of the cPAD; they are 1.8% of the cPAD for all infants (<1 year old),
the population group receiving the greatest exposure.
The short-term aggregate exposure assessment for children 1 to less
than 2 years old includes dietary (food and drinking water) and
incidental oral exposure from hand-to-mouth activities from post-
application exposure to turf. The short-term aggregate risk estimate
for children 1 to less than 2 years old is an MOE of 3,700, which is
greater than the level of concern of 100 and is not of concern. Acute
risks are not expected due to no adverse effect observed for a single
dose of rimsulfuron; and chronic aggregate risks to adults and children
are equivalent to the dietary (food and drinking water) risks for those
respective assessments and are not of concern. Because there is no
intermediate-term residential exposure and chronic dietary exposure has
already been assessed under the appropriately protective cPAD, no
further assessment of intermediate-term risk is necessary. Based on the
lack of evidence of carcinogenicity in two adequate rodent
carcinogenicity studies, rimsulfuron is not expected to pose a cancer
risk to humans.
Therefore, based on the risk assessments and information described
above, 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 rimsulfuron residues. More detailed information
on this action can be found in the document ``Rimsulfuron. Human Health
Risk Assessment in Support of a Petition for the Establishment of
Permanent Tolerances on Pomegranate and Tropical and Subtropical, Small
Fruit, Edible Peel, Subgroup 23A'' in docket ID No. EPA-HQ-OPP-2021-
0447.
IV. Other Considerations
A. Analytical Enforcement Methodology
For a discussion of the available analytical enforcement method for
various crops, see Unit IV.A of the February 12, 2018, rulemaking.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). Codex has not established MRLs for residues of
rimsulfuron in or on any commodity associated with this action.
V. Conclusion
Therefore, tolerances are established for residues of rimsulfuron
(N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2-
pyridinesulfonamide), in or on pomegranate at 0.01 ppm and tropical and
subtropical, small fruit, edible peel, subgroup 23A at 0.01 ppm.
In addition, as a housekeeping measure, EPA is removing the
tolerance for potato at 0.1 ppm, which expired on August 12, 2018, and
has no effect at this time.
VI. Statutory and Executive Order Reviews
This action establishes tolerances under FFDCA section 408(d) in
response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this action has been
exempted from review under Executive Order 12866, this action is not
subject to Executive Order 13211, entitled ``Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or Tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
Tribal Governments, on the relationship between the National Government
and the States or Tribal Governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian Tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November
[[Page 4735]]
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 (CRA)
Pursuant to the CRA (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).
