II. Summary of Petitioned-For
Tolerance
In the Federal Register of January 3,
2023 (88 FR 38) (FRL–9410–08–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 1E8966) by IR–4,
North Carolina State University, 1730
Varsity Drive, Venture IV, Suite 210,
Raleigh, NC 27606. The January 3, 2023,
document supersedes the document
published on April 28, 2022 (87 FR
25178) (FRL–9410–12–OCSPP). The
petition requested that 40 CFR part 180
be amended by establishing tolerances
for residues of trinexapac-ethyl in or on
the raw agricultural commodities clover,
forage at 8 parts per million (ppm) and
clover, hay at 15 ppm. As a result of
feeding clover that has been treated with
trinexapac-ethyl to livestock, the
following tolerances were proposed in
livestock commodities: cattle, fat and
cattle, meat at 0.03 ppm; cattle, meat
byproducts at 0.1 ppm; egg at 0.01 ppm;
goat, fat and goat, meat at 0.03 ppm;
goat, meat byproducts at 0.1 ppm; hog,
meat byproducts at 0.1 ppm; milk at
0.01 ppm; horse, meat at 0.03 ppm;
poultry, fat and poultry, meat at 0.01
ppm; poultry, meat byproducts at 0.1
ppm; sheep, fat and sheep, meat at 0.03
ppm; and sheep, meat byproducts at 0.1
ppm. That document referenced a
summary of the petition, which is
available in the docket, https://
www.regulations.gov. A comment was
received in response to the April 28,
2022, notice of filing. EPA’s response to
the comment 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
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 trinexapacethyl including exposure resulting from
the tolerances established by this action.
EPA’s assessment of exposures and risks
associated with trinexapac-ethyl
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 trinexapacethyl in which EPA concluded, based
on the available information, that there
is a reasonable certainty that no harm
would result from aggregate exposure to
trinexapac-ethyl 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.

published in the Federal Register of
March 2, 2012 (77 FR 12740) (FRL–
9337–9).
Exposure assessment. EPA’s dietary
exposure assessments have been
updated to include the additional
exposure from the proposed new
regional use on clover as well for
associated residues on animal
commodities. The assessments were
conducted with Dietary Exposure
Evaluation Model software using the
Food Commodity Intake Database
(DEEM–FCID) Version 4.02, which uses
the 2005–2010 food consumption data
from the United States Department of
Agriculture’s (USDA’s) National Health
and Nutrition Examination Survey,
What We Eat in America (NHANES/
WWEIA). The unrefined acute and
chronic dietary exposure assessments
used tolerance-level residues, EPA’s
default processing factors, and assumed
100 percent crop treated (PCT) for the
registered commodities.
Drinking water and non-occupational
exposures. The drinking water numbers
have not changed as a result of the new
use on clover. For a detailed summary
of the drinking water analysis for
trinexapac-ethyl used for the human
health risk assessment, please reference
Unit III.C.2. of the May 20, 2015,
rulemaking.
Trinexapac-ethyl is currently
registered for the following uses that
could result in residential exposures:
residential lawns, athletic fields, parks,
and golf courses. For a detailed
summary of the non-occupational
analysis for trinexapac-ethyl used for
the human health risk assessment,
please reference Unit III.C.3. of the May
20, 2015, rulemaking.
Cumulative exposure. 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
E:\FR\FM\29MRR1.SGM
29MRR1
ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 60 / Wednesday, March 29, 2023 / Rules and Regulations
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
trinexapac-ethyl and any other
substances. For the purposes of this
action, therefore, EPA has not assumed
that trinexapac-ethyl has a common
mechanism of toxicity with other
substances.
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 from 10X to
1X. See Unit III.D. of the May 20, 2015,
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 dietary exposure
estimates to the acute populationadjusted dose (aPAD) and chronic
population-adjusted dose (cPAD).
Short-, intermediate-, and chronic-term
aggregate risks are evaluated by
comparing the estimated total food,
water, and residential exposure to the
appropriate points of departure to
ensure that an adequate margin of
exposure (MOE) exists.
Acute dietary risks are below the
Agency’s level of concern of 100% of
the aPAD; they are 2.5% of the aPAD for
females 13 to 49 years old, the only
population group of concern. Chronic
dietary risks are below the Agency’s
level of concern of 100% of the cPAD;
they are 6.8% of the cPAD for children
1 to 2 years old, the group with the
highest exposure.
Short-term aggregate (average dietary
and residential turf exposures) MOEs for
adults (235) and youth (4,500) are above
EPA’s level of concern of 100 and are
not of concern. Trinexapac-ethyl is
classified as ‘‘not likely to be
carcinogenic to humans.’’ Therefore,
EPA does not expect trinexapac-ethyl to
pose a cancer risk from aggregate
exposure.
Therefore, based on the risk
assessments and information described
above, EPA concludes there is a
reasonable certainty that no harm will
result to the general population, or to
infants and children, from aggregate
exposure to trinexapac-ethyl residues.

‘‘Trinexapac-ethyl. Human Health Risk
Assessment for the New Use on Clover

IV. Other Considerations
A. Analytical Enforcement Methodology
For a discussion of the available
analytical enforcement method, see Unit
IV.A. of the May 20, 2015, 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).
There are no established Codex MRLs
on clover forage and hay. There are
established Codex MRLs for trinexapacethyl in or on livestock commodities.
The U.S. tolerances are harmonized
with Codex MRLs for ruminant and hog
meat byproduct at 0.1 ppm. However,
the ruminant and swine meat and fat
tolerances increased to 0.03 ppm
because there is the potential for
secondary transfer of trinexapac-ethyl
resides in ruminant meat from the new
use on clover. Because the U.S.
tolerances are higher based on the
estimated livestock dietary burden, it is
not possible to harmonize with the 0.01
ppm Codex MRL for ruminant and
swine meat and fat commodities.
C. Response to Comments
One comment was received on the
notice of filing, which opposed EPA
establishing the requested tolerances
and objected to the presence of pesticide
residues on crops. Although the Agency
recognizes that some individuals believe
that pesticides should be banned on
agricultural crops, the existing legal
framework provided by section 408 of
the FFDCA authorizes EPA to establish
tolerances when it determines that the
tolerances are safe. Upon consideration
of the validity, completeness, and
reliability of the available data as well
as other factors the FFDCA requires EPA
to consider, EPA has determined that
the trinexapac-ethyl tolerances are safe.
The commenter has provided no
information indicating that a safety
determination cannot be supported.
V. Conclusion
Therefore, tolerances are established
for residues of trinexapac-ethyl in or on
egg at 0.01 ppm; milk at 0.01 ppm;
poultry, fat at 0.01 ppm; poultry, meat
at 0.01 ppm; and poultry, meat
byproducts at 0.1 ppm. The following
established tolerances for residues of
trinexapac-ethyl are revised to the
specified levels: cattle, fat at 0.03 ppm;
PO 00000
Frm 00055
Fmt 4700
Sfmt 4700
18433
cattle, meat at 0.03 ppm; cattle, meat
byproducts at 0.1 ppm; goat, fat at 0.03
ppm; goat, meat at 0.03 ppm; goat, meat
byproducts at 0.1 ppm; hog, meat
byproducts at 0.1 ppm; horse, meat at
0.03 ppm; sheep, fat at 0.03 ppm; sheep,
meat at 0.03 ppm; and sheep, meat
byproducts at 0.1 ppm. Additionally,
tolerances with regional registrations are
established for residues of trinexapacethyl in or on clover, forage at 8 ppm
and clover, hay at 15 ppm.
As a housekeeping measure, EPA is
removing the word ‘‘imported’’ from the
commodity entry for ‘‘Poppy, seed
imported’’, as unnecessary and
redundant. Moreover, use of that
adjective is not consistent with how
EPA typically identifies tolerances for
residues in or on imported
commodities. The associated footnote 1
indicates that there are no U.S.
registrations for use of trinexapac-ethyl
on poppy seed; thus, the tolerance itself
is intended to cover residues on
imported commodities. Additionally,
footnote 1 is being added to the table as
identified in the March 15, 2018, final
tolerance rule. The changes have no
substantive effect and can be
accomplished without further notice
and comment.
VI. Statutory and Executive Order
Reviews
This action establishes a tolerance
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 to
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
E:\FR\FM\29MRR1.SGM
29MRR1
18434
Federal Register / Vol. 88, No. 60 / Wednesday, March 29, 2023 / Rules and Regulations
the tolerances in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or Tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or Tribal Governments, on the
relationship between the National
Government and the States or Tribal
Governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
Tribes. Thus, the Agency has
determined that Executive Order 13132,
entitled ‘‘Federalism’’ (64 FR 43255,
August 10, 1999), and Executive Order
13175, entitled ‘‘Consultation and
Coordination with Indian Tribal
Governments’’ (65 FR 67249, November
9, 2000), do not apply to this action. In
addition, this action does not impose
any enforceable duty or contain any
unfunded mandate as described under
Title II of the Unfunded Mandates
Reform Act (UMRA) (2 U.S.C. 1501 et
seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of the rule in the Federal
Register. This action is not a ‘‘major
rule’’ as defined by 5 U.S.C. 804(2).

II. Summary of Petitioned-For Tolerance
In the Federal Register of January 3, 2023 (88 FR 38) (FRL-9410-08-
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
1E8966) by IR-4, North Carolina State University, 1730 Varsity Drive,
Venture IV, Suite 210, Raleigh, NC 27606. The January 3, 2023, document
supersedes the document published on April 28, 2022 (87 FR 25178) (FRL-
9410-12-OCSPP). The petition requested that 40 CFR part 180 be amended
by establishing tolerances for residues of trinexapac-ethyl in or on
the raw agricultural commodities clover, forage at 8 parts per million
(ppm) and clover, hay at 15 ppm. As a result of feeding clover that has
been treated with trinexapac-ethyl to livestock, the following
tolerances were proposed in livestock commodities: cattle, fat and
cattle, meat at 0.03 ppm; cattle, meat byproducts at 0.1 ppm; egg at
0.01 ppm; goat, fat and goat, meat at 0.03 ppm; goat, meat byproducts
at 0.1 ppm; hog, meat byproducts at 0.1 ppm; milk at 0.01 ppm; horse,
meat at 0.03 ppm; poultry, fat and poultry, meat at 0.01 ppm; poultry,
meat byproducts at 0.1 ppm; sheep, fat and sheep, meat at 0.03 ppm; and
sheep, meat byproducts at 0.1 ppm. That document referenced a summary
of the petition, which is available in the docket, https://www.regulations.gov. A comment was received in response to the April
28, 2022, notice of filing. EPA's response to the comment 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 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 trinexapac-ethyl including exposure resulting
from the tolerances established by this action. EPA's assessment of
exposures and risks associated with trinexapac-ethyl 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 trinexapac-
ethyl in which EPA concluded, based on the available information, that
there is a reasonable certainty that no harm would result from
aggregate exposure to trinexapac-ethyl 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.
Toxicological profile. For a discussion of the Toxicological
Profile of trinexapac-ethyl, see Unit III.A. of the trinexapac-ethyl
tolerance rulemaking published in the Federal Register of May 20, 2015
(80 FR 28843) (FRL-9926-62).
Toxicological points of departure/Levels of concern. For a summary
of the Toxicological Points of Departure/Levels of Concern for
trinexapac-ethyl used for human health risk assessment, please
reference Unit III.B. of the trinexapac-ethyl tolerance rulemaking
published in the Federal Register of March 2, 2012 (77 FR 12740) (FRL-
9337-9).
Exposure assessment. EPA's dietary exposure assessments have been
updated to include the additional exposure from the proposed new
regional use on clover as well for associated residues on animal
commodities. The assessments were conducted with Dietary Exposure
Evaluation Model software using the Food Commodity Intake Database
(DEEM-FCID) Version 4.02, which uses the 2005-2010 food consumption
data from the United States Department of Agriculture's (USDA's)
National Health and Nutrition Examination Survey, What We Eat in
America (NHANES/WWEIA). The unrefined acute and chronic dietary
exposure assessments used tolerance-level residues, EPA's default
processing factors, and assumed 100 percent crop treated (PCT) for the
registered commodities.
Drinking water and non-occupational exposures. The drinking water
numbers have not changed as a result of the new use on clover. For a
detailed summary of the drinking water analysis for trinexapac-ethyl
used for the human health risk assessment, please reference Unit
III.C.2. of the May 20, 2015, rulemaking.
Trinexapac-ethyl is currently registered for the following uses
that could result in residential exposures: residential lawns, athletic
fields, parks, and golf courses. For a detailed summary of the non-
occupational analysis for trinexapac-ethyl used for the human health
risk assessment, please reference Unit III.C.3. of the May 20, 2015,
rulemaking.
Cumulative exposure. 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
[[Page 18433]]
based on a common mechanism of toxicity, EPA has not made a common
mechanism of toxicity finding as to trinexapac-ethyl and any other
substances. For the purposes of this action, therefore, EPA has not
assumed that trinexapac-ethyl has a common mechanism of toxicity with
other substances.
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 from 10X to 1X. See Unit
III.D. of the May 20, 2015, 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
dietary exposure estimates to the acute population-adjusted dose (aPAD)
and chronic population-adjusted dose (cPAD). Short-, intermediate-, and
chronic-term aggregate risks are evaluated by comparing the estimated
total food, water, and residential exposure to the appropriate points
of departure to ensure that an adequate margin of exposure (MOE)
exists.
Acute dietary risks are below the Agency's level of concern of 100%
of the aPAD; they are 2.5% of the aPAD for females 13 to 49 years old,
the only population group of concern. Chronic dietary risks are below
the Agency's level of concern of 100% of the cPAD; they are 6.8% of the
cPAD for children 1 to 2 years old, the group with the highest
exposure.
Short-term aggregate (average dietary and residential turf
exposures) MOEs for adults (235) and youth (4,500) are above EPA's
level of concern of 100 and are not of concern. Trinexapac-ethyl is
classified as ``not likely to be carcinogenic to humans.'' Therefore,
EPA does not expect trinexapac-ethyl to pose a cancer risk from
aggregate exposure.
Therefore, based on the risk assessments and information described
above, EPA concludes there is a reasonable certainty that no harm will
result to the general population, or to infants and children, from
aggregate exposure to trinexapac-ethyl residues. More detailed
information on this action can be found in the document titled
``Trinexapac-ethyl. Human Health Risk Assessment for the New Use on
Clover (Seed Crop).'' in docket ID EPA-HQ-OPP-2022-0069.
IV. Other Considerations
A. Analytical Enforcement Methodology
For a discussion of the available analytical enforcement method,
see Unit IV.A. of the May 20, 2015, 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).
There are no established Codex MRLs on clover forage and hay. There
are established Codex MRLs for trinexapac-ethyl in or on livestock
commodities. The U.S. tolerances are harmonized with Codex MRLs for
ruminant and hog meat byproduct at 0.1 ppm. However, the ruminant and
swine meat and fat tolerances increased to 0.03 ppm because there is
the potential for secondary transfer of trinexapac-ethyl resides in
ruminant meat from the new use on clover. Because the U.S. tolerances
are higher based on the estimated livestock dietary burden, it is not
possible to harmonize with the 0.01 ppm Codex MRL for ruminant and
swine meat and fat commodities.
C. Response to Comments
One comment was received on the notice of filing, which opposed EPA
establishing the requested tolerances and objected to the presence of
pesticide residues on crops. Although the Agency recognizes that some
individuals believe that pesticides should be banned on agricultural
crops, the existing legal framework provided by section 408 of the
FFDCA authorizes EPA to establish tolerances when it determines that
the tolerances are safe. Upon consideration of the validity,
completeness, and reliability of the available data as well as other
factors the FFDCA requires EPA to consider, EPA has determined that the
trinexapac-ethyl tolerances are safe. The commenter has provided no
information indicating that a safety determination cannot be supported.
V. Conclusion
Therefore, tolerances are established for residues of trinexapac-
ethyl in or on egg at 0.01 ppm; milk at 0.01 ppm; poultry, fat at 0.01
ppm; poultry, meat at 0.01 ppm; and poultry, meat byproducts at 0.1
ppm. The following established tolerances for residues of trinexapac-
ethyl are revised to the specified levels: cattle, fat at 0.03 ppm;
cattle, meat at 0.03 ppm; cattle, meat byproducts at 0.1 ppm; goat, fat
at 0.03 ppm; goat, meat at 0.03 ppm; goat, meat byproducts at 0.1 ppm;
hog, meat byproducts at 0.1 ppm; horse, meat at 0.03 ppm; sheep, fat at
0.03 ppm; sheep, meat at 0.03 ppm; and sheep, meat byproducts at 0.1
ppm. Additionally, tolerances with regional registrations are
established for residues of trinexapac-ethyl in or on clover, forage at
8 ppm and clover, hay at 15 ppm.
As a housekeeping measure, EPA is removing the word ``imported''
from the commodity entry for ``Poppy, seed imported'', as unnecessary
and redundant. Moreover, use of that adjective is not consistent with
how EPA typically identifies tolerances for residues in or on imported
commodities. The associated footnote 1 indicates that there are no U.S.
registrations for use of trinexapac-ethyl on poppy seed; thus, the
tolerance itself is intended to cover residues on imported commodities.
Additionally, footnote 1 is being added to the table as identified in
the March 15, 2018, final tolerance rule. The changes have no
substantive effect and can be accomplished without further notice and
comment.
VI. Statutory and Executive Order Reviews
This action establishes a tolerance 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 to 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
[[Page 18434]]
the tolerances in this final rule, do not require the issuance of a
proposed rule, the requirements of the Regulatory Flexibility Act (RFA)
(5 U.S.C. 601 et seq.), do not apply.
This action directly regulates growers, food processors, food
handlers, and food retailers, not States or Tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
Tribal Governments, on the relationship between the National Government
and the States or Tribal Governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian Tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999), and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000), do not apply to this action. In addition,
this action does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
EPA will submit a report containing this rule and other required
information to the U.S. Senate, the U.S. House of Representatives, and
the Comptroller General of the United States prior to publication of
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
