Distribution, or Use (66 FR 28355, May
22, 2001). 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., or 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). 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); or OMB review or any Agency
action under Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
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
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. In addition, the
Agency has determined that this action
will not have a substantial direct effect
on States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, entitled
Federalism(64 FR 43255, August 10,
1999). Executive Order 13132 requires
EPA to develop an accountable process
to ensure ‘‘meaningful and timely input
by State and local officials in the
development of regulatory policies that
have federalism implications.’’ ‘‘Policies
that have federalism implications’’ is
defined in the Executive Order to
include regulations that have
‘‘substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.’’ This final rule
directly regulates growers, food
processors, food handlers and food
retailers, not States. This action does not
alter the relationships or distribution of
power and responsibilities established
by Congress in the preemption
provisions of section 408(n)(4) of
VerDate Aug<31>2005

FFDCA. For these same reasons, the
Agency has determined that this rule
does not have any ‘‘tribal implications’’
as described in Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive
Order 13175, requires EPA to develop
an accountable process to ensure
‘‘meaningful and timely input by tribal
officials in the development of
regulatory policies that have tribal
implications.’’ ‘‘Policies that have tribal
implications’’ is defined in the
Executive Order to include regulations
that have ‘‘substantial direct effects on
one or more Indian tribes, on the
relationship between the Federal
Government and the Indian tribes, or on
the distribution of power and
responsibilities between the Federal
Government and Indian tribes.’’ This
rule will not have substantial direct
effects on tribal governments, on the
relationship between the Federal
Government and Indian tribes, or on the
distribution of power and
responsibilities between the Federal
Government and Indian tribes, as
specified in Executive Order 13175.
Thus, Executive Order 13175 does not
apply to this rule.
VIII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, 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 final
rule in the Federal Register. This final
rule is not a ‘‘major rule’’ as defined by
5 U.S.C. 804(2).

ACTION: Final rule.
AGENCY:
SUMMARY: This regulation establishes
tolerances for residues of boscalid, 3pyridinecarboxamide, 2-chloro-N-(4′chloro [1,1′-biphenyl]-2-yl) in or on
banana (imported), celery, and spinach.
In addition, existing tolerances are being
increased on almond hulls. Finally, the
existing lettuce exception listed for the
indirect or inadvertent residues in
vegetables, leafy, group 4, is being
revised to include celery and spinach,
as well as lettuce. BASF requested the
tolerances on almonds and bananas, and
Interregional Research Project #4 (IR-4)
has proposed group tolerances on
vegetable, leafy, except brassica, Group
4 (to include celery and spinach), under
the Federal Food, Drug, and Cosmetic
Act (FFDCA), as amended by the Food
Quality Protection Act of 1996 (FQPA).

II. Background and Statutory Findings
In the Federal Register of July 6, 2005
(70 FR 38911) (FRL–7721–5), EPA
issued a notice pursuant to section
408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filings of
pesticide petitions (PP 4F6875, 3E6791,
5E6933) by BASF Corporation, P.O. Box
13528, Research Triangle Park, NC
27709 and IR-4. The petition requested
that 180.589 be amended by establishing
a tolerance for residues of the fungicide
boscalid, 3-pyridinecarboxamide, 2chloro-N-(4′-chloro(1,1′-biphenyl)-2-yl,
in or on the raw agricultural commodity
almond, hulls at 15 parts per millions
(ppm) (PP 4F6875), vegetable, leafy,
except brassica, Group 4 at 50 ppm (PP
3E6791), and banana at 0.5 ppm (PP
5E6933). That notice included a
summary of the pesticide petition
prepared by BASF, the registrant.
Comments were received on the notice
of filing. EPA’s response to these
comments is discussed in Unit IV
below.
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
PO 00000
Frm 00024
Fmt 4700
Sfmt 4700
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....’’
EPA performs a number of analyses to
determine the risks from aggregate
exposure to pesticide residues. For
further discussion of the regulatory
requirements of section 408 of the
FFDCA and a complete description of
the risk assessment process, see https://
www.epa.gov/fedrgstr/EPA-PEST/1997/
November/Day-26/p30948.htm.
III. Aggregate Risk Assessment and
Determination of Safety
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. EPA has sufficient data to assess
the hazards of and to make a
determination on aggregate exposure,
consistent with section 408(b)(2) of
FFDCA, for a tolerance for residues of
boscalid on almond hulls at 17 ppm,
banana (imported) at 0.20 ppm, celery at
45 ppm, and spinach at 60 ppm. IR-4
requested a 50 ppm group tolerance for
vegetable, leafy, except brassica in
Group 4. However, the requested
Boscalid tolerance for this entire group
is inappropriate because the proposed
50 ppm group tolerance is substantially
higher than the existing 11 ppm
tolerance for the representative lettuce
member of this group. Therefore, based
on the submitted data, separate
tolerances are established for the celery
and spinach members in this group. The
existing lettuce exception listed in 40
CFR 180.589(d) for indirect or
inadvertent residues in vegetables, leafy,
group 4, is being revised to include
celery, and spinach, as well as lettuce.
This is because of the separate
tolerances established herein for celery
and spinach in 40 CFR 180.589(a).
EPA’s assessment of exposures and risks
associated with establishing the
tolerance follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its validity,
completeness, and reliability as well as
E:\FR\FM\08FER1.SGM
08FER1
Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations
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. Specific
information on the studies received and
the nature of the toxic effects caused by
boscalid 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 in the Federal Register of July
30, 2003 (68 FR 44640) (FRL–7319–6).
rmajette on PROD1PC67 with RULES1
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, the dose at which no adverse
effects are observed (the NOAEL) from
the toxicology study identified as
appropriate for use in risk assessment is
used to estimate the toxicological level
of concern (LOC). However, the lowest
dose at which adverse effects of concern
are identified (the LOAEL) is sometimes
used for risk assessment if no NOAEL
was achieved in the toxicology study
selected. An uncertainty factor (UF) is
applied to reflect uncertainties inherent
in the extrapolation from laboratory
animal data to humans and in the
variations in sensitivity among members
of the human population as well as
other unknowns.
The linear default risk methodology
(Q*) is the primary method currently
used by the Agency to quantify nonthreshold hazards such as cancer. The
Q* approach assumes that any amount
of exposure will lead to some degree of
cancer risk, estimates risk in terms of
the probability of occurrence of
additional cancer cases.
A summary of the toxicological
endpoints for boscalid used for human
risk assessment is discussed in Unit
III.B. of the final rule published in the
Federal Register of July 30, 2003 (68 FR
44640).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. Tolerances have been
established (40 CFR 180.589) for the
residues of boscalid, in or on a variety
of raw agricultural commodities. Risk
assessments were conducted by EPA to
assess dietary exposures from boscalid
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
identified in the toxicological studies
VerDate Aug<31>2005
15:23 Feb 07, 2006
Jkt 208001
for Boscalid; therefore, a quantitative
acute dietary exposure assessment is
unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the Dietary Exposure
Evaluation Model software with the
Food Commodity Intake Database
(DEEM-FCIDTM), which incorporates
food consumption data as reported by
respondents in the United States
Department of Agriculture (USDA)
1994–1996 and 1998 Nationwide
Continuing Surveys of Food Intake by
Individuals (CSFII), and accumulated
exposure to the chemical for each
commodity. The following assumptions
were made for the chronic exposure
assessments:
The assessment was based on
tolerance-level residues (in some cases
modified by DEEM (Version 7.81)
default processing factors), and assumed
100% crop treated.
iii. Cancer. A quantitative cancer
exposure assessment is not necessary
because EPA concluded that boscalid is
unlikely to pose a carcinogenic risk to
humans. This conclusion was based on
the following weight of evidence
considerations. First, in male Wistar
rats, there was a significant trend (but
not pairwise comparison) for the
combined thyroid adenomas and
carcinomas. This trend was driven by
the increase in adenomas. Second, in
the female rats, there was only a
borderline significant trend for thyroid
adenomas (there were no carcinomas).
Third, the mouse study was negative as
were all of the mutagenic tests. Based on
this weak evidence of carcinogenic
effects, the Agency concluded that
boscalid is not expected to pose a
carcinogenic risk.
2. Dietary exposure from drinking
water. The Agency lacks sufficient
monitoring exposure data to complete a
comprehensive dietary exposure
analysis and risk assessment for
boscalid in drinking water. Because the
Agency does not have comprehensive
monitoring data, drinking water
concentration estimates are made by
reliance on simulation or modeling
taking into account data on the physical
characteristics of boscalid.
The Agency used the FQPA Index
Reservoir Screening Tool (FIRST) or the
Pesticide Root Zone Model/Exposure
Analysis Modeling System (PRZM/
EXAMS), to produce estimates of
pesticide concentrations in an index
reservoir. The screening concentration
in ground water (SCI-GROW) model is
used to predict pesticide concentrations
in shallow ground water. For a
screening-level assessment for surface
water EPA will use FIRST (a Tier 1
PO 00000
Frm 00025
Fmt 4700
Sfmt 4700
6361
model) before using PRZM/EXAMS (a
Tier 2 model). The FIRST model is a
subset of the PRZM/EXAMS model that
uses a specific high-end runoff scenario
for pesticides. Both FIRST and PRZM/
EXAMS incorporate an index reservoir
environment, and both models include
a percent crop area factor as an
adjustment to account for the maximum
percent crop coverage within a
watershed or drainage basin. None of
these models include consideration of
the impact processing (mixing, dilution,
or treatment) of raw water for
distribution as drinking water would
likely have on the removal of pesticides
from the source water. The primary use
of these models by the Agency at this
stage is to provide a screen for sorting
out pesticides for which it is unlikely
that drinking water concentrations
would exceed human health levels of
concern. EECs derived from these
models are used to quantify drinking
water exposure and risk as a %RfD or
%PAD.
Based on the FIRST and SCI-GROW
models, the estimated environmental
concentrations (EECs) of boscalid for
acute exposures are estimated to be
87.53 parts per billion (ppb) for surface
water and 0.63 ppb for ground water.
The EECs for chronic exposures are
estimated to be 25.77 ppb for surface
water and 0.63 ppb for ground 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).
Residential exposure to boscalid is
possible on golf courses and at ‘‘U-pick’’
farms and orchards. A non-occupational
dermal post-application exposure/risk
assessment for these exposusres was
conducted in the previous occupational
and residential exposure (ORE)
assessment and is described in the final
rule dated July 30, 2003 ( 68 FR 44640).
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of the 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
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
boscalid and any other substances and
boscalid does not appear to produce a
E:\FR\FM\08FER1.SGM
08FER1
6362
Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations
rmajette on PROD1PC67 with RULES1
toxic metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has not
assumed that boscalid has a common
mechanism of toxicity with other
substances. 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/.
D. Safety Factor for Infants and
Children
1. In general. Section 408 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 on
toxicity and exposure unless EPA
determines based on reliable data that a
different margin of safety will be safe for
infants and children. Margins of safety
are incorporated into EPA risk
assessments either directly through use
of a margin of exposure (MOE) analysis
or through using uncertainty (safety)
factors in calculating a dose level that
poses no appreciable risk to humans. In
applying this provision, EPA either
retains the default value of 10X when
reliable data do not support the choice
of a different factor, or, if reliable data
are available, EPA uses a different
additional safety factor value based on
the use of traditional uncertainty factors
and/or special FQPA safety factors, as
appropriate.
2. Prenatal and postnatal sensitivity.
A complete discussion of the prenatal/
postnatal sensitivity study was recently
discussed in the final rule dated July 30,
2003 (68 FR 44640). No new
information has been received to change
this information. The Agency concluded
that there are no residual uncertainties
for pre- and post-natal toxicity as the
degree of concern is low for
susceptibility, as evidenced by the data
in the studies for the rodent and nonrodent prenatal developmental,
reproduction and fertility effects, and
the acute, subchronic and
developmental neurotoxicity studies.
3. Conclusion. There is a complete
toxicity data base for boscalid and
exposure data are complete or are
estimated based on data that reasonably
accounts for potential exposures. There
is no evidence of susceptibility
VerDate Aug<31>2005
15:23 Feb 07, 2006
Jkt 208001
following in utero exposure to rats and
there is low concern and no residual
uncertainties in the developmental
neurotoxicity study after establishing
toxicity endpoints and traditional
uncertainty factors for intraspecies
variability and interspecies
extrapolation of 100X used in the risk
assessment. Based on these data and
conclusions, EPA reduced the FQPA
safety factor to 1X.
E. Aggregate Risks and Determination of
Safety
1. Acute risk. As there were no toxic
effects attributable to a single dose, an
endpoint of concern was not identified
to quantitate acute-dietary risk to the
general population or to the
subpopulation females 13–50 years old.
No acute risk is expected from exposure
to boscalid.
2. Chronic risk. The chronic dietary
exposure analysis was based on
tolerance-level residues (in some cases
modified by DEEM (Version 7.81)
default processing factors), and assumes
100% crop treated. Even with these
highly conservative assumptions, the
risk estimates are well below the
Agency’s LOC. The most highly exposed
population subgroup from DEEM is
children 1–2 years, which has an
exposure estimate of 0.067 mg/kg/day,
and utilizes 31% of the chronic
population adjusted dose (Cpad).
3. Short-term risk. Short-term
aggregate exposure takes into account
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level). In
this case, the non-occupational uses to
be aggregated with dietary exposure are
the turf use on golf courses and u-pick
farms. Post-application exposures from
these uses is considered short-term, and
applies to adults and youth. Therefore,
a short-term aggregate risk assessment
was conducted. As all endpoints are
from the same study, exposures from
different routes can be aggregated. The
exposure to residues in drinking water
were included in the dietary exposure
analysis. As a result, the aggregate
exposure is the sum of two exposure
values: Dietary (food + water) and
residential. The target maximum daily
exposure to boscalid residues is 0.22
mg/kg/day. The sum of the food, water,
and residential exposures is 0.021 mg/
kg/day. As a result, the short-term
aggregate risk of exposure to boscalid
residues is below the Agency’s LOC.
The exposure estimate was calculated
using the general U.S. population, but is
considered to be representative of youth
because youth and adults possess
similar body surface area to weight
ratios and because the dietary exposure
PO 00000
Frm 00026
Fmt 4700
Sfmt 4700
for youth (13–19 years old) is less than
that of the general U.S. population.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account residential exposure
plus chronic exposure to food and water
(considered to be a background
exposure level).
Because no intermediate term, nonoccupational exposures are anticipated
from the use of Boscalid, boscalid is not
expected to pose an intermediate-term
risk.
5. Aggregate cancer risk for U.S.
population. Based on the weight of the
evidence evaluation described
previously herein, EPA concluded that
boscalid is not expected to pose a
carcinogenic 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, and to infants and children
from aggregate exposure to boscalid
residues.
IV. Other Considerations

and electron capture detection) is

expression. The method may be

B. International Residue Limits
There are currently no International
or Codex maximum residue levels
(MRLs) for boscalid.
C. Response to Comments
One comment dated 7/9/05 was
received from B. Sachau. Ms. Sachau’s
comments regarding general exposure to
pesticides contained no scientific data
or evidence to rebut the Agency’s
conclusion that there is a reasonable
certainty that no harm will result from
aggregate exposure to Boscalid,
including all anticipated dietary
exposures and other exposures for
which there is reliable information. This
comment as well as her comments
regarding animal testing have been
responded to by the Agency on several
occasions. For example, 70 FR 1349
(January 7, 2005)(FRL–7691–4); 69 FR
63083 (October 29, 2004)(FRL–7681–9).
V. Conclusion
Therefore, tolerances are established
for residues of boscalid, 3pyridinecarboxamide, 2-chloro-N-(4′-
E:\FR\FM\08FER1.SGM
08FER1
Federal Register / Vol. 71, No. 26 / Wednesday, February 8, 2006 / Rules and Regulations
chloro[1,1′-biphenyl]-2-yl), in or on
banana (imported) at 0.20 ppm, celery at
45 ppm and spinach at 60 ppm. The
existing 3.0 ppm tolerance on almond
hulls is being increased to 17 ppm.
IR-4 requested a 50 ppm group
tolerance for vegetable, leafy, except
brassica in Group 4. However, the
requested Boscalid tolerance for this
entire group is inappropriate because
the proposed 50 ppm group tolerance is
substantially higher than the existing 11
ppm tolerance for the representative
lettuce member of this group. Therefore,
based on the submitted data, separate
tolerances are established for the celery
and spinach members in this group.
The existing lettuce exception listed
in 40 CFR 180.589(d) for indirect or
inadvertent residues in vegetables, leafy,
group 4, is being revised to include
celery, and spinach, as well as lettuce.
This is because of the separate
tolerances established herein for celery
and spinach in 40 CFR 180.589(a).

VI. Objections and Hearing Requests
Under section 408(g) of FFDCA, as
amended by FQPA, any person may file
an objection to any aspect of this
regulation and may also request a
hearing on those objections. The EPA
procedural regulations which govern the
submission of objections and requests
for hearings appear in 40 CFR part 178.
Although the procedures in those
regulations require some modification to
reflect the amendments made to FFDCA
by FQPA, EPA will continue to use
those procedures, with appropriate
adjustments, until the necessary
modifications can be made. The new
section 408(g) of FFDCA provides
essentially the same process for persons
to ‘‘object’’ to a regulation for an
exemption from the requirement of a
tolerance issued by EPA under new
section 408(d) of FFDCA, as was
provided in the old sections 408 and
409 of FFDCA. However, the period for
filing objections is now 60 days, rather
than 30 days.

material submitted shows the following:
There is a genuine and substantial issue
of fact; there is a reasonable possibility
that available evidence identified by the
requestor would, if established resolve
one or more of such issues in favor of
the requestor, taking into account
uncontested claims or facts to the
contrary; and resolution of the factual
issue(s) in the manner sought by the
requestor would be adequate to justify
the action requested (40 CFR 178.32).
VII. 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 types
of actions from review under Executive
Order 12866, entitled Regulatory
Planning and Review (58 FR 51735,
October 4, 1993). Because this rule has
been exempted from review under
Executive Order 12866 due to its lack of
significance, this rule is not subject to
Executive Order 13211, Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001). 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., or 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). 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); or OMB review or any Agency
action under Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
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
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. In addition, the
Agency has determined that this action
will not have a substantial direct effect

on States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132, entitled
Federalism(64 FR 43255, August 10,
1999). Executive Order 13132 requires
EPA to develop an accountable process
to ensure ‘‘meaningful and timely input
by State and local officials in the
development of regulatory policies that
have federalism implications.’’ ‘‘Policies
that have federalism implications’’ is
defined in the Executive order to
include regulations that have
‘‘substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government.’’ This final rule
directly regulates growers, food
processors, food handlers and food
retailers, not States. This action does not
alter the relationships or distribution of
power and responsibilities established
by Congress in the preemption
provisions of section 408(n)(4) of
FFDCA. For these same reasons, the
Agency has determined that this rule
does not have any ‘‘tribal implications’’
as described in Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive
Order 13175, requires EPA to develop
an accountable process to ensure
‘‘meaningful and timely input by tribal
officials in the development of
regulatory policies that have tribal
implications.’’ ‘‘Policies that have tribal
implications’’ is defined in the
Executive order to include regulations
that have ‘‘substantial direct effects on
one or more Indian tribes, on the
relationship between the Federal
Government and the Indian tribes, or on
the distribution of power and
responsibilities between the Federal
Government and Indian tribes.’’ This
rule will not have substantial direct
effects on tribal governments, on the
relationship between the Federal
Government and Indian tribes, or on the
distribution of power and
responsibilities between the Federal
Government and Indian tribes, as
specified in Executive Order 13175.
Thus, Executive Order 13175 does not
apply to this rule.
VIII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must

submit a rule report, which includes a
copy of the rule, 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 final
rule in the Federal Register. This final
rule is not a ‘‘major rule’’ as defined by
5 U.S.C. 804(2).

Boscalid; Pesticide Tolerance
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This regulation establishes tolerances for residues of
boscalid, 3-pyridinecarboxamide, 2-chloro-N-(4'-chloro [1,1'-biphenyl]-
2-yl) in or on banana (imported), celery, and spinach. In addition,
existing tolerances are being increased on almond hulls. Finally, the
existing lettuce exception listed for the indirect or inadvertent
residues in vegetables, leafy, group 4, is being revised to include
celery and spinach, as well as lettuce. BASF requested the tolerances
on almonds and bananas, and Interregional Research Project 4
(IR-4) has proposed group tolerances on vegetable, leafy, except
brassica, Group 4 (to include celery and spinach), under the Federal
Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality
Protection Act of 1996 (FQPA).
[[Page 6360]]
DATES: This regulation is effective February 8, 2006. Objections and
requests for hearings must be received on or before April 10, 2006.

is available at E-CFR Beta Site Two at https://www.gpoaccess.gov/ecfr/.
II. Background and Statutory Findings
In the Federal Register of July 6, 2005 (70 FR 38911) (FRL-7721-5),
EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filings of pesticide petitions (PP 4F6875,
3E6791, 5E6933) by BASF Corporation, P.O. Box 13528, Research Triangle
Park, NC 27709 and IR-4. The petition requested that 180.589 be amended
by establishing a tolerance for residues of the fungicide boscalid, 3-
pyridinecarboxamide, 2-chloro-N-(4'-chloro(1,1'-biphenyl)-2-yl, in or
on the raw agricultural commodity almond, hulls at 15 parts per
millions (ppm) (PP 4F6875), vegetable, leafy, except brassica, Group 4
at 50 ppm (PP 3E6791), and banana at 0.5 ppm (PP 5E6933). That notice
included a summary of the pesticide petition prepared by BASF, the
registrant. Comments were received on the notice of filing. EPA's
response to these comments is discussed in Unit IV below.
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....''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see https://www.epa.gov/
fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
III. Aggregate Risk Assessment and Determination of Safety
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. EPA has sufficient data to assess the hazards of and to
make a determination on aggregate exposure, consistent with section
408(b)(2) of FFDCA, for a tolerance for residues of boscalid on almond
hulls at 17 ppm, banana (imported) at 0.20 ppm, celery at 45 ppm, and
spinach at 60 ppm. IR-4 requested a 50 ppm group tolerance for
vegetable, leafy, except brassica in Group 4. However, the requested
Boscalid tolerance for this entire group is inappropriate because the
proposed 50 ppm group tolerance is substantially higher than the
existing 11 ppm tolerance for the representative lettuce member of this
group. Therefore, based on the submitted data, separate tolerances are
established for the celery and spinach members in this group. The
existing lettuce exception listed in 40 CFR 180.589(d) for indirect or
inadvertent residues in vegetables, leafy, group 4, is being revised to
include celery, and spinach, as well as lettuce. This is because of the
separate tolerances established herein for celery and spinach in 40 CFR
180.589(a). EPA's assessment of exposures and risks associated with
establishing the tolerance follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as
[[Page 6361]]
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. Specific information on the studies received and
the nature of the toxic effects caused by boscalid 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 in the
Federal Register of July 30, 2003 (68 FR 44640) (FRL-7319-6).
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the dose at which no adverse effects are observed
(the NOAEL) from the toxicology study identified as appropriate for use
in risk assessment is used to estimate the toxicological level of
concern (LOC). However, the lowest dose at which adverse effects of
concern are identified (the LOAEL) is sometimes used for risk
assessment if no NOAEL was achieved in the toxicology study selected.
An uncertainty factor (UF) is applied to reflect uncertainties inherent
in the extrapolation from laboratory animal data to humans and in the
variations in sensitivity among members of the human population as well
as other unknowns.
The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases.
A summary of the toxicological endpoints for boscalid used for
human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of July 30, 2003 (68 FR 44640).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. Tolerances have been
established (40 CFR 180.589) for the residues of boscalid, in or on a
variety of raw agricultural commodities. Risk assessments were
conducted by EPA to assess dietary exposures from boscalid 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
identified in the toxicological studies for Boscalid; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the Dietary Exposure Evaluation Model software with
the Food Commodity Intake Database (DEEM-FCID\TM\), which incorporates
food consumption data as reported by respondents in the United States
Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII), and
accumulated exposure to the chemical for each commodity. The following
assumptions were made for the chronic exposure assessments:
The assessment was based on tolerance-level residues (in some cases
modified by DEEM (Version 7.81) default processing factors), and
assumed 100% crop treated.
iii. Cancer. A quantitative cancer exposure assessment is not
necessary because EPA concluded that boscalid is unlikely to pose a
carcinogenic risk to humans. This conclusion was based on the following
weight of evidence considerations. First, in male Wistar rats, there
was a significant trend (but not pairwise comparison) for the combined
thyroid adenomas and carcinomas. This trend was driven by the increase
in adenomas. Second, in the female rats, there was only a borderline
significant trend for thyroid adenomas (there were no carcinomas).
Third, the mouse study was negative as were all of the mutagenic tests.
Based on this weak evidence of carcinogenic effects, the Agency
concluded that boscalid is not expected to pose a carcinogenic risk.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring exposure data to complete a comprehensive dietary
exposure analysis and risk assessment for boscalid in drinking water.
Because the Agency does not have comprehensive monitoring data,
drinking water concentration estimates are made by reliance on
simulation or modeling taking into account data on the physical
characteristics of boscalid.
The Agency used the FQPA Index Reservoir Screening Tool (FIRST) or
the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/
EXAMS), to produce estimates of pesticide concentrations in an index
reservoir. The screening concentration in ground water (SCI-GROW) model
is used to predict pesticide concentrations in shallow ground water.
For a screening-level assessment for surface water EPA will use FIRST
(a Tier 1 model) before using PRZM/EXAMS (a Tier 2 model). The FIRST
model is a subset of the PRZM/EXAMS model that uses a specific high-end
runoff scenario for pesticides. Both FIRST and PRZM/EXAMS incorporate
an index reservoir environment, and both models include a percent crop
area factor as an adjustment to account for the maximum percent crop
coverage within a watershed or drainage basin. None of these models
include consideration of the impact processing (mixing, dilution, or
treatment) of raw water for distribution as drinking water would likely
have on the removal of pesticides from the source water. The primary
use of these models by the Agency at this stage is to provide a screen
for sorting out pesticides for which it is unlikely that drinking water
concentrations would exceed human health levels of concern. EECs
derived from these models are used to quantify drinking water exposure
and risk as a %RfD or %PAD.
Based on the FIRST and SCI-GROW models, the estimated environmental
concentrations (EECs) of boscalid for acute exposures are estimated to
be 87.53 parts per billion (ppb) for surface water and 0.63 ppb for
ground water. The EECs for chronic exposures are estimated to be 25.77
ppb for surface water and 0.63 ppb for ground 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).
Residential exposure to boscalid is possible on golf courses and at
``U-pick'' farms and orchards. A non-occupational dermal post-
application exposure/risk assessment for these exposusres was conducted
in the previous occupational and residential exposure (ORE) assessment
and is described in the final rule dated July 30, 2003 ( 68 FR 44640).
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the 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 based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to boscalid and any other
substances and boscalid does not appear to produce a
[[Page 6362]]
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has not assumed that boscalid has a
common mechanism of toxicity with other substances. 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/.
D. Safety Factor for Infants and Children
1. In general. Section 408 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 on toxicity and exposure
unless EPA determines based on reliable data that a different margin of
safety will be safe for infants and children. Margins of safety are
incorporated into EPA risk assessments either directly through use of a
margin of exposure (MOE) analysis or through using uncertainty (safety)
factors in calculating a dose level that poses no appreciable risk to
humans. In applying this provision, EPA either retains the default
value of 10X when reliable data do not support the choice of a
different factor, or, if reliable data are available, EPA uses a
different additional safety factor value based on the use of
traditional uncertainty factors and/or special FQPA safety factors, as
appropriate.
2. Prenatal and postnatal sensitivity. A complete discussion of the
prenatal/postnatal sensitivity study was recently discussed in the
final rule dated July 30, 2003 (68 FR 44640). No new information has
been received to change this information. The Agency concluded that
there are no residual uncertainties for pre- and post-natal toxicity as
the degree of concern is low for susceptibility, as evidenced by the
data in the studies for the rodent and non-rodent prenatal
developmental, reproduction and fertility effects, and the acute,
subchronic and developmental neurotoxicity studies.
3. Conclusion. There is a complete toxicity data base for boscalid
and exposure data are complete or are estimated based on data that
reasonably accounts for potential exposures. There is no evidence of
susceptibility following in utero exposure to rats and there is low
concern and no residual uncertainties in the developmental
neurotoxicity study after establishing toxicity endpoints and
traditional uncertainty factors for intraspecies variability and
interspecies extrapolation of 100X used in the risk assessment. Based
on these data and conclusions, EPA reduced the FQPA safety factor to
1X.
E. Aggregate Risks and Determination of Safety
1. Acute risk. As there were no toxic effects attributable to a
single dose, an endpoint of concern was not identified to quantitate
acute-dietary risk to the general population or to the subpopulation
females 13-50 years old. No acute risk is expected from exposure to
boscalid.
2. Chronic risk. The chronic dietary exposure analysis was based on
tolerance-level residues (in some cases modified by DEEM (Version 7.81)
default processing factors), and assumes 100% crop treated. Even with
these highly conservative assumptions, the risk estimates are well
below the Agency's LOC. The most highly exposed population subgroup
from DEEM is children 1-2 years, which has an exposure estimate of
0.067 mg/kg/day, and utilizes 31% of the chronic population adjusted
dose (Cpad).
3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). In this case, the non-
occupational uses to be aggregated with dietary exposure are the turf
use on golf courses and u-pick farms. Post-application exposures from
these uses is considered short-term, and applies to adults and youth.
Therefore, a short-term aggregate risk assessment was conducted. As all
endpoints are from the same study, exposures from different routes can
be aggregated. The exposure to residues in drinking water were included
in the dietary exposure analysis. As a result, the aggregate exposure
is the sum of two exposure values: Dietary (food + water) and
residential. The target maximum daily exposure to boscalid residues is
0.22 mg/kg/day. The sum of the food, water, and residential exposures
is 0.021 mg/kg/day. As a result, the short-term aggregate risk of
exposure to boscalid residues is below the Agency's LOC. The exposure
estimate was calculated using the general U.S. population, but is
considered to be representative of youth because youth and adults
possess similar body surface area to weight ratios and because the
dietary exposure for youth (13-19 years old) is less than that of the
general U.S. population.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account residential exposure plus chronic exposure to food
and water (considered to be a background exposure level).
Because no intermediate term, non-occupational exposures are
anticipated from the use of Boscalid, boscalid is not expected to pose
an intermediate-term risk.
5. Aggregate cancer risk for U.S. population. Based on the weight
of the evidence evaluation described previously herein, EPA concluded
that boscalid is not expected to pose a carcinogenic 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, and to infants and children from aggregate
exposure to boscalid residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography, mass
spectrometry and electron capture detection) 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; e-mail
address: residuemethods@epa.gov.
B. International Residue Limits
There are currently no International or Codex maximum residue
levels (MRLs) for boscalid.
C. Response to Comments
One comment dated 7/9/05 was received from B. Sachau. Ms. Sachau's
comments regarding general exposure to pesticides contained no
scientific data or evidence to rebut the Agency's conclusion that there
is a reasonable certainty that no harm will result from aggregate
exposure to Boscalid, including all anticipated dietary exposures and
other exposures for which there is reliable information. This comment
as well as her comments regarding animal testing have been responded to
by the Agency on several occasions. For example, 70 FR 1349 (January 7,
2005)(FRL-7691-4); 69 FR 63083 (October 29, 2004)(FRL-7681-9).
V. Conclusion
Therefore, tolerances are established for residues of boscalid, 3-
pyridinecarboxamide, 2-chloro-N-(4'-
[[Page 6363]]
chloro[1,1'-biphenyl]-2-yl), in or on banana (imported) at 0.20 ppm,
celery at 45 ppm and spinach at 60 ppm. The existing 3.0 ppm tolerance
on almond hulls is being increased to 17 ppm.
IR-4 requested a 50 ppm group tolerance for vegetable, leafy,
except brassica in Group 4. However, the requested Boscalid tolerance
for this entire group is inappropriate because the proposed 50 ppm
group tolerance is substantially higher than the existing 11 ppm
tolerance for the representative lettuce member of this group.
Therefore, based on the submitted data, separate tolerances are
established for the celery and spinach members in this group.
The existing lettuce exception listed in 40 CFR 180.589(d) for
indirect or inadvertent residues in vegetables, leafy, group 4, is
being revised to include celery, and spinach, as well as lettuce. This
is because of the separate tolerances established herein for celery and
spinach in 40 CFR 180.589(a).
VI. Objections and Hearing Requests
Under section 408(g) of FFDCA, as amended by FQPA, any person may
file an objection to any aspect of this regulation and may also request
a hearing on those objections. The EPA procedural regulations which
govern the submission of objections and requests for hearings appear in
40 CFR part 178. Although the procedures in those regulations require
some modification to reflect the amendments made to FFDCA by FQPA, EPA
will continue to use those procedures, with appropriate adjustments,
until the necessary modifications can be made. The new section 408(g)
of FFDCA provides essentially the same process for persons to
``object'' to a regulation for an exemption from the requirement of a
tolerance issued by EPA under new section 408(d) of FFDCA, as was
provided in the old sections 408 and 409 of FFDCA. However, the period
for filing objections is now 60 days, rather than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must
identify docket ID number EPA-HQ-OPP-2005-0145 in the subject line on
the first page of your submission. All requests must be in writing, and
must be mailed or delivered to the Hearing Clerk on or before April 10,
2006.
1. Filing the request. Your objection must specify the specific
provisions in the regulation that you object to, and the grounds for
the objections (40 CFR 178.25). If a hearing is requested, the
objections must include a statement of the factual issue(s) on which a
hearing is requested, the requestor's contentions on such issues, and a
summary of any evidence relied upon by the objector (40 CFR 178.27).
Information submitted in connection with an objection or hearing
request may be claimed confidential by marking any part or all of that
information as CBI. Information so marked will not be disclosed except
in accordance with procedures set forth in 40 CFR part 2. A copy of the
information that does not contain CBI must be submitted for inclusion
in the public record. Information not marked confidential may be
disclosed publicly by EPA without prior notice.
Mail your written request to: Office of the Hearing Clerk (1900L),
Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. You may also deliver your request to the
Office of the Hearing Clerk in Suite 350, 1099 14th St., NW.,
Washington, DC 20005. The Office of the Hearing Clerk is open from 8
a.m. to 4 p.m., Monday through Friday, excluding legal holidays. The
telephone number for the Office of the Hearing Clerk is (202) 564-6255.
2. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VI.A., you
should also send a copy of your request to the PIRIB for its inclusion
in the official record that is described in ADDRESSES. Mail your
copies, identified by docket ID number EPA-HQ-OPP-2005-0145, to: Public
Information and Records Integrity Branch, Information Technology and
Resources Management Division (7502C), Office of Pesticide Programs,
Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, DC 20460-0001. In person or by courier, bring a copy to the
location of the PIRIB described in ADDRESSES. You may also send an
electronic copy of your request via e-mail to: opp-docket@epa.gov.
Please use an ASCII file format and avoid the use of special characters
and any form of encryption. Copies of electronic objections and hearing
requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII
file format. Do not include any CBI in your electronic copy. You may
also submit an electronic copy of your request at many Federal
Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issue(s) in the manner sought
by the requestor would be adequate to justify the action requested (40
CFR 178.32).
VII. 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 types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this rule has been
exempted from review under Executive Order 12866 due to its lack of
significance, this rule is not subject to Executive Order 13211,
Actions Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May 22, 2001). 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., or 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). 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); or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). 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 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. In addition, the Agency has determined that this
action will not have a substantial direct effect
[[Page 6364]]
on States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132,
entitled Federalism(64 FR 43255, August 10, 1999). Executive Order
13132 requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.'' This final
rule directly regulates growers, food processors, food handlers and
food retailers, not States. This action does not alter the
relationships or distribution of power and responsibilities established
by Congress in the preemption provisions of section 408(n)(4) of FFDCA.
For these same reasons, the Agency has determined that this rule does
not have any ``tribal implications'' as described in Executive Order
13175, entitled Consultation and Coordination with Indian Tribal
Governments (65 FR 67249, November 6, 2000). Executive Order 13175,
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by tribal officials in the development of regulatory
policies that have tribal implications.'' ``Policies that have tribal
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on one or more Indian tribes, on
the relationship between the Federal Government and the Indian tribes,
or on the distribution of power and responsibilities between the
Federal Government and Indian tribes.'' This rule will not have
substantial direct effects on tribal governments, on the relationship
between the Federal Government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this rule.
VIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
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 final rule in the Federal Register. This final
rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
