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 final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
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 of 1995
(NTTAA), Public Law 104–113, section

II. Background and Statutory Findings
In the Federal Register of January 6,
2010 (75 FR 864) (FRL–8801–5), EPA
issued a notice pursuant to section 408
PO 00000
Frm 00040
Fmt 4700
Sfmt 4700
of FFDCA, 21 U.S.C. 346a, announcing
the receipt of a pesticide petition (PP
9E7634) filed by Wacker Chemical
Corporation, 3301 Sutton Rd., Adrian,
MI 49221–9397. The petition requested
that 40 CFR 180.960 be amended by
establishing an exemption from the
requirement of a tolerance for residues
of tetraethoxysilane, polymer with
hexamethyldisiloxane, minimum
number average molecular weight (in
AMU) 2,500, (CAS No. 104133–09–7).
That notice included a summary of the
petition prepared by the petitioner and
solicited comments on the petitioner’s
request. The Agency did not receive any
comments.
Section 408(c)(2)(A)(i) of FFDCA
allows EPA to establish an exemption
from the requirement for 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(c)(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
use 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 an
exemption from the requirement of 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. . .’’ and specifies
factors EPA is to consider in
establishing an exemption.
III. Risk Assessment and Statutory
Findings
EPA establishes exemptions from the
requirement of a tolerance only in those
cases where it can be shown that the
risks from aggregate exposure to
pesticide chemical residues under
reasonably foreseeable circumstances
will pose no appreciable risks to human
health. In order to determine the risks
from aggregate exposure to pesticide
inert ingredients, the Agency considers
the toxicity of the inert in conjunction
with possible exposure to residues of
the inert ingredient through food,
drinking water, and through other
exposures that occur as a result of
pesticide use in residential settings. If
EPA is able to determine that a finite
tolerance is not necessary to ensure that
there is a reasonable certainty that no
harm will result from aggregate

wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
Federal Register / Vol. 75, No. 51 / Wednesday, March 17, 2010 / Rules and Regulations
exposure to the inert ingredient, an
exemption from the requirement of a
tolerance may be established.
Consistent with section 408(b)(2)(D)
of FFDCA, EPA has reviewed the
available scientific data and other
relevant information in support of this
action and considered its validity,
completeness and reliability and the
relationship of this information 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. In the
case of certain chemical substances that
are defined as polymers, the Agency has
established a set of criteria to identify
categories of polymers expected to
present minimal or no risk. The
definition of a polymer is given in 40
CFR 723.250(b) and the exclusion
criteria for identifying these low-risk
polymers are described in 40 CFR
723.250(d). Tetraethoxysilane, polymer
with hexamethyldisiloxane, conforms to
the definition of a polymer given in 40
CFR 723.250(b) and meets the following
criteria that are used to identify low-risk
polymers.
1. The polymer is not a cationic
polymer nor is it reasonably anticipated
to become a cationic polymer in a
natural aquatic environment.
2. The polymer does contain as an
integral part of its composition the
atomic elements carbon, hydrogen, and
oxygen.
3. The polymer does not contain as an
integral part of its composition, except
as impurities, any element other than
those listed in 40 CFR 723.250(d)(2)(ii).
4. The polymer is neither designed
nor can it be reasonably anticipated to
substantially degrade, decompose, or
depolymerize.
5. The polymer is manufactured or
imported from monomers and/or
reactants that are already included on
the TSCA Chemical Substance
Inventory or manufactured under an
applicable TSCA section 5 exemption.
6. The polymer is not a water
absorbing polymer with a number
average molecular weight (MW) greater
than or equal to 10,000 daltons.
Additionally, the polymer also meets
as required the following exemption
criteria specified in 40 CFR 723.250(e).
7. The polymer’s number average MW
of 2,500 daltons is greater than 1,000
and less than 10,000 daltons. The
polymer contains less than 10%
oligomeric material below MW 500 and
less than 25% oligomeric material
below MW 1,000, and the polymer does
not contain any reactive functional
groups.
VerDate Nov<24>2008
14:47 Mar 16, 2010
Jkt 220001
Thus, tetraethoxysilane, polymer with
hexamethyldisiloxane, meets the criteria
for a polymer to be considered low risk
under 40 CFR 723.250. Based on its
conformance to the criteria in this unit,
no mammalian toxicity is anticipated
from dietary, inhalation, or dermal
exposure to tetraethoxysilane, polymer
with hexamethyldisiloxane.
IV. Aggregate Exposures
For the purposes of assessing
potential exposure under this
exemption, EPA considered that
tetraethoxysilane, polymer with
hexamethyldisiloxane could be present
in all raw and processed agricultural
commodities and drinking water, and
that non-occupational non-dietary
exposure was possible. The number
average MW of tetraethoxysilane,
polymer with hexamethyldisiloxane is
2,500 daltons. Generally, a polymer of
this size would be poorly absorbed
through the intact gastrointestinal tract
or through intact human skin. Since
tetraethoxysilane, polymer with
hexamethyldisiloxane conform to the
criteria that identify a low-risk polymer,
there are no concerns for risks
associated with any potential exposure
scenarios that are reasonably
foreseeable. The Agency has determined
that a tolerance is not necessary to
protect the public health.
V. Cumulative Effects
Section 408 (b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance or tolerance exemption, the
Agency consider ‘‘available information’’
concerning the cumulative effects of a
particular chemical’s residues and
‘‘other substances that have a common
mechanism of toxicity.’’ For the
purposes of this tolerance action, EPA
has not assumed that tetraethoxysilane,
polymer with hexamethyldisiloxane has
a common mechanism of toxicity with
other substances, based on the
anticipated absence of mammalian
toxicity. For information regarding
EPA’s efforts to determine which
chemicals have a common mechanism
of toxicity and to evaluate the
cumulative effects of such chemicals,
see the policy statements released by
EPA’s Office of Pesticide Programs
concerning common mechanism
determinations and procedures for
cumulating effects from substances
found to have a common mechanism on
EPA’s website at https://www.epa.gov/
pesticides/cumulative.

VI. Additional Safety Factor for the
Protection of Infants and Children
Section 408(b)(2)(C) of FFDCA
provides that EPA shall apply an
additional tenfold 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 data base unless
EPA concludes that a different margin of
safety will be safe for infants and
children. Due to the expected low
toxicity of tetraethoxysilane, polymer
with hexamethyldisiloxane, EPA has
not used a safety factor analysis to
assess the risk. For the same reasons the
additional tenfold safety factor is
unnecessary.
VII. Determination of Safety
Based on the conformance to the
criteria used to identify a low-risk
polymer, EPA concludes that there is a
reasonable certainty of no harm to the
U.S. population, including infants and
children, from aggregate exposure to
residues of tetraethoxysilane, polymer
with hexamethyldisiloxane.
VIII. Other Considerations
A. Endocrine Disruptor
EPA is required under the Federal
Food, Drug and Cosmetic Act (FFDCA),
as amended by FQPA, to develop a
screening program to determine whether
certain substances (including all
pesticide active and other ingredients)
‘‘may have an effect in humans that is
similar to an effect produced by a
naturally occurring estrogen, or other
such endocrine effects as the
Administrator may designate.’’
Following recommendations of its
Endocrine Disruptor and Testing
Advisory Committee (EDSTAC), EPA
determined that there was a scientific
basis for including, as part of the
program, the androgen and thyroid
hormone systems, in addition to the
estrogen hormone system. EPA also
adopted EDSTAC’s recommendation
that the Program include evaluations of
potential effects in wildlife. For
pesticide chemicals, EPA will use
FIFRA and, to the extent that effects in
wildlife may help determine whether a
substance may have an effect in
humans, FFDCA authority to require the
wildlife evaluations. As the science
develops and resources allow, screening
of additional hormone systems may be
added to the Endocrine Disruptor
Screening Program (EDSP).
When additional appropriate
screening and/or testing protocols being
considered under the Agency’s EDSP
have been developed tetraethoxysilane,
polymer with hexamethyldisiloxane
E:\FR\FM\17MRR1.SGM
17MRR1
12698
Federal Register / Vol. 75, No. 51 / Wednesday, March 17, 2010 / Rules and Regulations
may be subjected to further screening
and/or testing to better characterize
effects related to endocrine disruption.
B. Analytical Enforcement Methodology
An analytical method is not required
for enforcement purposes since the
Agency is establishing an exemption
from the requirement of a tolerance
without any numerical limitation.
C. International Tolerances
The Agency is not aware of any
country requiring a tolerance for
tetraethoxysilane, polymer with
hexamethyldisiloxane, nor have any
CODEX Maximum Residue Levels
(MRLs) been established for any food
crops at this time.
IX. Conclusion
Accordingly, EPA finds that
exempting residues of tetraethoxysilane,
polymer with hexamethyldisiloxane,
from the requirement of a tolerance will
be safe.

X. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these rules
from review under Executive Order
12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993).
Because this final rule has been
exempted from review under Executive
Order 12866, this final rule 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 final rule 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 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 of 1995 (NTTAA),
Public Law 104–113, section 12(d) (15
U.S.C. 272 note).
Since tolerances and exemptions that
are established on the basis of a petition
under section 408(d) of FFDCA, 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.
VerDate Nov<24>2008
14:47 Mar 16, 2010
Jkt 220001
This final rule 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 section 408(n)(4) of FFDCA. 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, or otherwise have any unique
impacts or local governments. 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 final rule.
In addition, this final rule does not
impose any enforceable duty or contain
any unfunded mandate as described
under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public
Law 104–4).
Although this action does not 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), EPA seeks to
achieve environmental justice, the fair
treatment and meaningful involvement
of any group, including minority and/or
low-income populations, in the
development, implementation, and
enforcement of environmental laws,
regulations, and policies. As such, to the
extent that information is publicly
available or was submitted in comments
to EPA, the Agency considered whether
groups or segments of the population, as
a result of their location, cultural
practices, or other factors, may have
atypical or disproportionately high and
adverse human health impacts or
environmental effects from exposure to
the pesticide discussed in this
document, compared to the general
population.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of this rule in the Federal
Register. This rule is not a ‘‘major rule’’
as defined by 5 U.S.C. 804(2).
XI. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. EPA will
submit a report containing this rule and
other required information to the U.S.

ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 180
[EPA-HQ-OPP-2009-0845; FRL-8814-3]
Tetraethoxysilane, Polymer with Hexamethyldisiloxane; Tolerance
Exemption
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes an exemption from the requirement
of a tolerance for residues of tetraethoxysilane, polymer with
hexamethyldisiloxane, minimum number average molecular weight (in AMU)
2,500 (CAS Reg. No. 104133-09-7) when used as an inert ingredient in a
pesticide chemical formulation under 40 CFR 180.960. Wacker Chemical
Corporation submitted a petition to EPA under the Federal Food, Drug,
and Cosmetic Act (FFDCA), requesting an exemption from the requirement
of a tolerance. This regulation eliminates the need to establish a
maximum permissible level for residues of tetraethoxysilane, polymer
with hexamethyldisiloxane, on food or feed commodities.
DATES: This regulation is effective March 17, 2010. Objections and
requests for hearings must be received on or before May 17, 2010, and
must be filed in accordance with the instructions provided in 40 CFR
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings
In the Federal Register of January 6, 2010 (75 FR 864) (FRL-8801-
5), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C.
346a, announcing the receipt of a pesticide petition (PP 9E7634) filed
by Wacker Chemical Corporation, 3301 Sutton Rd., Adrian, MI 49221-9397.
The petition requested that 40 CFR 180.960 be amended by establishing
an exemption from the requirement of a tolerance for residues of
tetraethoxysilane, polymer with hexamethyldisiloxane, minimum number
average molecular weight (in AMU) 2,500, (CAS No. 104133-09-7). That
notice included a summary of the petition prepared by the petitioner
and solicited comments on the petitioner's request. The Agency did not
receive any comments.
Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an
exemption from the requirement for 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(c)(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 use 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 an exemption from the
requirement of 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. . .'' and
specifies factors EPA is to consider in establishing an exemption.
III. Risk Assessment and Statutory Findings
EPA establishes exemptions from the requirement of a tolerance only
in those cases where it can be shown that the risks from aggregate
exposure to pesticide chemical residues under reasonably foreseeable
circumstances will pose no appreciable risks to human health. In order
to determine the risks from aggregate exposure to pesticide inert
ingredients, the Agency considers the toxicity of the inert in
conjunction with possible exposure to residues of the inert ingredient
through food, drinking water, and through other exposures that occur as
a result of pesticide use in residential settings. If EPA is able to
determine that a finite tolerance is not necessary to ensure that there
is a reasonable certainty that no harm will result from aggregate
[[Page 12697]]
exposure to the inert ingredient, an exemption from the requirement of
a tolerance may be established.
Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action and considered its validity, completeness and reliability
and the relationship of this information 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. In the case of certain chemical substances that
are defined as polymers, the Agency has established a set of criteria
to identify categories of polymers expected to present minimal or no
risk. The definition of a polymer is given in 40 CFR 723.250(b) and the
exclusion criteria for identifying these low-risk polymers are
described in 40 CFR 723.250(d). Tetraethoxysilane, polymer with
hexamethyldisiloxane, conforms to the definition of a polymer given in
40 CFR 723.250(b) and meets the following criteria that are used to
identify low-risk polymers.
1. The polymer is not a cationic polymer nor is it reasonably
anticipated to become a cationic polymer in a natural aquatic
environment.
2. The polymer does contain as an integral part of its composition
the atomic elements carbon, hydrogen, and oxygen.
3. The polymer does not contain as an integral part of its
composition, except as impurities, any element other than those listed
in 40 CFR 723.250(d)(2)(ii).
4. The polymer is neither designed nor can it be reasonably
anticipated to substantially degrade, decompose, or depolymerize.
5. The polymer is manufactured or imported from monomers and/or
reactants that are already included on the TSCA Chemical Substance
Inventory or manufactured under an applicable TSCA section 5 exemption.
6. The polymer is not a water absorbing polymer with a number
average molecular weight (MW) greater than or equal to 10,000 daltons.
Additionally, the polymer also meets as required the following
exemption criteria specified in 40 CFR 723.250(e).
7. The polymer's number average MW of 2,500 daltons is greater than
1,000 and less than 10,000 daltons. The polymer contains less than 10%
oligomeric material below MW 500 and less than 25% oligomeric material
below MW 1,000, and the polymer does not contain any reactive
functional groups.
Thus, tetraethoxysilane, polymer with hexamethyldisiloxane, meets
the criteria for a polymer to be considered low risk under 40 CFR
723.250. Based on its conformance to the criteria in this unit, no
mammalian toxicity is anticipated from dietary, inhalation, or dermal
exposure to tetraethoxysilane, polymer with hexamethyldisiloxane.
IV. Aggregate Exposures
For the purposes of assessing potential exposure under this
exemption, EPA considered that tetraethoxysilane, polymer with
hexamethyldisiloxane could be present in all raw and processed
agricultural commodities and drinking water, and that non-occupational
non-dietary exposure was possible. The number average MW of
tetraethoxysilane, polymer with hexamethyldisiloxane is 2,500 daltons.
Generally, a polymer of this size would be poorly absorbed through the
intact gastrointestinal tract or through intact human skin. Since
tetraethoxysilane, polymer with hexamethyldisiloxane conform to the
criteria that identify a low-risk polymer, there are no concerns for
risks associated with any potential exposure scenarios that are
reasonably foreseeable. The Agency has determined that a tolerance is
not necessary to protect the public health.
V. Cumulative Effects
Section 408 (b)(2)(D)(v) of FFDCA requires that, when considering
whether to establish, modify, or revoke a tolerance or tolerance
exemption, the Agency consider ``available information'' concerning the
cumulative effects of a particular chemical's residues and ``other
substances that have a common mechanism of toxicity.'' For the purposes
of this tolerance action, EPA has not assumed that tetraethoxysilane,
polymer with hexamethyldisiloxane has a common mechanism of toxicity
with other substances, based on the anticipated absence of mammalian
toxicity. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see the policy statements
released by EPA's Office of Pesticide Programs concerning common
mechanism determinations and procedures for cumulating effects from
substances found to have a common mechanism on EPA's website at https://www.epa.gov/pesticides/cumulative.
VI. Additional Safety Factor for the Protection of Infants and Children
Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an
additional tenfold 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 data base unless EPA concludes
that a different margin of safety will be safe for infants and
children. Due to the expected low toxicity of tetraethoxysilane,
polymer with hexamethyldisiloxane, EPA has not used a safety factor
analysis to assess the risk. For the same reasons the additional
tenfold safety factor is unnecessary.
VII. Determination of Safety
Based on the conformance to the criteria used to identify a low-
risk polymer, EPA concludes that there is a reasonable certainty of no
harm to the U.S. population, including infants and children, from
aggregate exposure to residues of tetraethoxysilane, polymer with
hexamethyldisiloxane.
VIII. Other Considerations
A. Endocrine Disruptor
EPA is required under the Federal Food, Drug and Cosmetic Act
(FFDCA), as amended by FQPA, to develop a screening program to
determine whether certain substances (including all pesticide active
and other ingredients) ``may have an effect in humans that is similar
to an effect produced by a naturally occurring estrogen, or other such
endocrine effects as the Administrator may designate.'' Following
recommendations of its Endocrine Disruptor and Testing Advisory
Committee (EDSTAC), EPA determined that there was a scientific basis
for including, as part of the program, the androgen and thyroid hormone
systems, in addition to the estrogen hormone system. EPA also adopted
EDSTAC's recommendation that the Program include evaluations of
potential effects in wildlife. For pesticide chemicals, EPA will use
FIFRA and, to the extent that effects in wildlife may help determine
whether a substance may have an effect in humans, FFDCA authority to
require the wildlife evaluations. As the science develops and resources
allow, screening of additional hormone systems may be added to the
Endocrine Disruptor Screening Program (EDSP).
When additional appropriate screening and/or testing protocols
being considered under the Agency's EDSP have been developed
tetraethoxysilane, polymer with hexamethyldisiloxane
[[Page 12698]]
may be subjected to further screening and/or testing to better
characterize effects related to endocrine disruption.
B. Analytical Enforcement Methodology
An analytical method is not required for enforcement purposes since
the Agency is establishing an exemption from the requirement of a
tolerance without any numerical limitation.
C. International Tolerances
The Agency is not aware of any country requiring a tolerance for
tetraethoxysilane, polymer with hexamethyldisiloxane, nor have any
CODEX Maximum Residue Levels (MRLs) been established for any food crops
at this time.
IX. Conclusion
Accordingly, EPA finds that exempting residues of
tetraethoxysilane, polymer with hexamethyldisiloxane, from the
requirement of a tolerance will be safe.
X. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these rules from review under
Executive Order 12866, entitled Regulatory Planning and Review (58 FR
51735, October 4, 1993). Because this final rule has been exempted from
review under Executive Order 12866, this final rule 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 final rule 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 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 of 1995 (NTTAA), Public Law 104-113, section 12(d) (15
U.S.C. 272 note).
Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, 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 final rule 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 section 408(n)(4) of FFDCA. 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, or otherwise have any unique
impacts or local governments. 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 final rule. In addition, this final rule does not impose
any enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law
104-4).
Although this action does not 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), EPA seeks to achieve
environmental justice, the fair treatment and meaningful involvement of
any group, including minority and/or low-income populations, in the
development, implementation, and enforcement of environmental laws,
regulations, and policies. As such, to the extent that information is
publicly available or was submitted in comments to EPA, the Agency
considered whether groups or segments of the population, as a result of
their location, cultural practices, or other factors, may have atypical
or disproportionately high and adverse human health impacts or
environmental effects from exposure to the pesticide discussed in this
document, compared to the general population.
XI. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. 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 this rule in the Federal
Register. This rule is not a ``major rule'' as defined by 5 U.S.C.
804(2).
