7. Unfunded Mandates Reform Act
The Unfunded Mandates Reform Act
of 1995 (2 U.S.C. 1531–1538) requires
Federal agencies to assess the effects of
their discretionary regulatory actions. In
particular, the Act addresses actions
that may result in the expenditure by a
State, local, or tribal government, in the
aggregate, or by the private sector of
$100,000,000 (adjusted for inflation) or
more in any one year. Though this rule
will not result in such an expenditure,
we do discuss the effects of this rule
elsewhere in this preamble.
8. Taking of Private Property
This rule will not cause a taking of
private property or otherwise have
taking implications under Executive
Order 12630, Governmental Actions and
Interference with Constitutionally
Protected Property Rights.
9. Civil Justice Reform
This rule meets applicable standards
in sections 3(a) and 3(b)(2) of Executive
Order 12988, Civil Justice Reform, to
minimize litigation, eliminate
ambiguity, and reduce burden.
10. Protection of Children
We have analyzed this rule under
Executive Order 13045, Protection of
Children from Environmental Health
Risks and Safety Risks. This rule is not
an economically significant rule and
does not create an environmental risk to
health or risk to safety that may
disproportionately affect children.

11. Indian Tribal Governments
This rule does not have tribal
implications under Executive Order
13175, Consultation and Coordination
with Indian Tribal Governments,
because it does not have a substantial
direct effect on one or more Indian
tribes, 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.
12. Energy Effects
This action is not a ‘‘significant
energy action’’ under Executive Order
13211, Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use.
13. Technical Standards
This rule does not use technical
standards. Therefore, we did not
consider the use of voluntary consensus
standards.

14. Environment
We have analyzed this rule under
Department of Homeland Security
Management Directive 023–01 and
Commandant Instruction M16475.lD,
which guide the Coast Guard in
complying with the National
Environmental Policy Act of 1969
(NEPA) (42 U.S.C. 4321–4370f), and
have determined that this action is one
of a category of actions that do not
individually or cumulatively have a
significant effect on the human
environment. This rule involves the
establishment of a safety zone and,
therefore it is categorically excluded
from further review under paragraph
34(g) of Figure 2–1 of the Commandant
Instruction. An environmental analysis
checklist supporting this determination
and a Categorical Exclusion
Determination are available in the
docket where indicated under
ADDRESSES. We seek any comments or
information that may lead to the
discovery of a significant environmental
impact from this rule.

II. Summary of Petitioned-For
Tolerance
In the Federal Register of May 23,
2014 (79 FR 29729) (FRL–9910–29),
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 3F8191) by Valent
U.S.A. Corporation, 1600 Riviera
Avenue, Suite 200, Walnut Creek, CA
94596. The petition requested that 40
CFR 180.627 be amended by
establishing tolerances for residues of
the fungicide fluopicolide, 2,6-dichloroN-[[3-chloro-5-(trifluoromethyl)-2pyridinyl]methyl]benzamide, in or on
potato, processed waste at 0.3 parts per
million (ppm); and vegetable, tuberous
and corm, subgroup 1C at 0.3 ppm. That
document referenced a summary of the
petition prepared by Valent U.S.A.
Corporation, the registrant, which is
available in the docket, https://
www.regulations.gov. Comments were
received on the notice of filing. EPA’s
PO 00000
Frm 00017
Fmt 4700
Sfmt 4700
45689
response to these comments is
discussed in Unit IV.C.
Based upon review of the data
supporting the petition, EPA has revised
the proposed tolerance in or on potato,
processed waste from 0.3 ppm to 1.0
ppm, and has revised the commodity
terminology. The reasons for these
changes are explained in Unit IV.D.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
Consistent with FFDCA section
408(b)(2)(D), and the factors specified in
FFDCA section 408(b)(2)(D), EPA has
reviewed the available scientific data
and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure for fluopicolide
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with fluopicolide follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its validity,
completeness, and reliability as well as
the relationship of the results of the
studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children.
Fluopicolide shares a metabolite, 2,6dichlorobenzamide (BAM), with another
active ingredient, dichlobenil. Residues
of BAM are considered to be of
regulatory concern, and separate
toxicity data and endpoints for risk
assessment have been identified for
E:\FR\FM\06AUR1.SGM
06AUR1
tkelley on DSK3SPTVN1PROD with RULES
45690
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
BAM. However, since increased
tolerances on the commodities affected
by this action do not add significantly
to the BAM dietary exposure, the
conclusions from the most recently
conducted BAM human health risk
assessment remain unchanged.
The subchronic and chronic toxicity
studies for fluopicolide showed that the
primary effects following exposure are
in the liver. Kidney and thyroid toxicity
were observed in rats only. Fluopicolide
is not neurotoxic, carcinogenic, nor
mutagenic. Developmental toxicity in
the rabbit occurred only at doses that
caused severe maternal toxicity,
including death. In the rat,
developmental effects were seen only at
high dose levels, in the presence of
maternal toxicity. Similarly, offspring
effects (decreased body weight and body
weight gain) in the multi-generation
reproductive toxicity study occurred
only at levels causing significant
toxicity in parents. There is no evidence
of increased quantitative susceptibility
of rat or rabbit fetuses to in utero or
postnatal exposure to fluopicolide. No
toxic effects were observed in studies in
which fluopicolide was administered by
the dermal routes of exposure. The
toxicological profile for fluopicolide
suggests that increased durations of
exposure do not significantly increase
the severity of observed effects. Toxic
effects observed in the rabbit
developmental and rat chronic/cancer
studies were selected as risk assessment
endpoints for all durations of exposure.
Fluopicolide is classified as not likely to
be carcinogenic to humans and no
quantification of cancer risks is
required.
The toxicity profile for BAM has not
changed since the last assessment EPA
conducted for BAM; an analysis of the
toxicology profile of BAM can be found
in ‘‘2,6-Dichlorobenzamide (BAM). 2,6Dichlorobenzamide (BAM) as a
Metabolite/Degradate of Fluopicolide

Vegetables,’’ pp. 31–35 in docket ID
number EPA–HQ–OPP–2014–0225.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm.
A summary of the toxicological
endpoints for fluopicolide and BAM
used for human risk assessment is
discussed in Unit III.B. of the final rule
published in the Federal Register of
April 20, 2011 (76 FR 22045) (FRL–
8859–9).
C. Exposure Assessment
The fluopicolide exposure assessment
considers exposure from fluopicolide
only. EPA did not reassess exposures
from BAM since the proposed change in
use pattern does not add significantly to
the BAM dietary exposure, and residues
of BAM due to fluopicolide applications
are significantly lower than those from
dichlobenil applications. EPA is relying
on conclusions from the 2008 BAM
Human Health Risk Assessment, which
remain unchanged. A discussion of how
BAM exposures were assessed can be
found in Unit III.C. of the final rule
published in the Federal Register of
August 27, 2008 (73 FR 50563) (FRL–
8377–7).
1. Dietary exposure from food and
feed uses. In evaluating dietary
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
exposure to fluopicolide, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing fluopicolide tolerances in 40
CFR 180.627. EPA assessed dietary
exposures from fluopicolide 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 fluopicolide; 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 Food
Commodity Intake Database (DEEM–
FCID) Version 3.16. This software uses
2003–2008 food consumption data from
the U.S. Department of Agriculture’s
(USDA’s) National Health and Nutrition
Examination Survey, What We Eat in
America (NHANES/WWEIA). As to
residue levels in food, EPA assumed 100
percent crop treated (PCT) and
tolerance-level residues. iii. Cancer.
Based on the data summarized in Unit
III.A., EPA has concluded that
fluopicolide does not pose a cancer risk
to humans. Therefore, a quantitative
dietary exposure assessment for the
purpose of assessing cancer risk is
unnecessary.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue and/or PCT
information in the dietary assessment
for fluopicolide. Tolerance level
residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for fluopicolide in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
fluopicolide. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www.epa.gov/
oppefed1/models/water/index.htm.
Based on the surface water
concentrations estimated using the
Pesticide Root Zone Model/Exposure
Analysis Modeling System (PRZM/
EXAMS); and Screening Concentrations
in Ground Water (SCI–GROW) models,
the estimated environmental
concentrations (EECs) of fluopicolide for
chronic exposure (non-cancer)
assessments are estimated to be 24.14

ppb for surface water and 0.5 ppb for
ground water. Acute and cancer dietary
risks were not quantified, as previously
discussed.
3. From non-dietary exposure. i. 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).
ii. Fluopicolide is currently registered
for the use on residential turf grass,
recreational sites, and ornamental plants
that could result in short-term
residential exposures. EPA assessed
residential exposure using the following
assumptions:
a. Residential handler short-term
dermal and inhalation exposures to
fluopicolide when mixing, loading, and
applying the formulations.
b. Residential post-application
exposures via the dermal route for
adults and children entering treated
lawns or treated gardens and during
mowing and golfing activities. and
c. Incidental non-dietary ingestion
(i.e., hand-to-mouth, object-to-mouth,
and soil ingestion) by children during
post-application activities on treated
turf.
Further information regarding EPA
standard assumptions and generic
inputs for residential exposures may be
found at https://www.epa.gov/pesticides/
trac/science/trac6a05.pdf.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
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
fluopicolide and any other substances.
Although fluopicolide shares a common
metabolite, BAM, with dichlobenil,
quantification of risks for residues of
BAM resulting from fluopicolide was
not done as part of this assessment
because they contribute an insignificant
amount to the total BAM exposure.
Furthermore, aggregate risks to BAM are
not of concern. For the purposes of this
tolerance action, EPA has not assumed
that fluopicolide 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 Web site at:
https://www.epa.gov/pesticides/
cumulative/.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(C) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA Safety Factor (SF). In applying
this provision, EPA either retains the
default value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
There is no evidence of quantitative
susceptibility following in utero and/or
postnatal fluopicolide exposure in the
rabbit and rat developmental toxicity
studies or in the 2-generation rat
reproduction study. Qualitative
susceptibility was observed in the rat
developmental toxicity study. In this
study, fetal effects (reduced growth and
skeletal defects) and late-term abortions
were observed at doses at which only
decreased body weight gain were
observed in maternal animals. There is
low concern for this qualitative
susceptibility because the fetal effects
and late-term abortions have been well
characterized and only occurred at a
dose level near the limit dose.
Protection for the maternal effects also
protects for any effects that may occur
during development. There are no
residual uncertainties concerning
prenatal and postnatal toxicity for
fluopicolide.
3. Conclusion regarding fluopicolide.
EPA has determined that reliable data
show the safety of infants and children
would be adequately protected if the
FQPA SF were reduced to 1X. That
decision is based on the following
findings:
i. The toxicity database for
fluopicolide is complete.
ii. There is no indication that
fluopicolide is a neurotoxic chemical
and there is no need for a
PO 00000
Frm 00019
Fmt 4700
Sfmt 4700
45691
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is no evidence that
fluopicolide results in increased
susceptibility in in utero rabbits in the
prenatal developmental studies or in
young rats in the 2-generation
reproduction study. Although there was
some evidence of qualitative
susceptibility in the rat developmental
toxicity study, as discussed in Unit
III.D.2., the degree of concern for the
prenatal and/or postnatal toxicity is
low; thus, there is no need for the 10X
FQPA safety factor to account for
potential prenatal or postnatal toxicity.
iv. There are no residual uncertainties
identified in the exposure databases.
The chronic dietary food exposure
assessments were performed based on
100 PCT and tolerance-level residues.
EPA made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to fluopicolide in drinking water.
Although EPA has required additional
data on transferable residues from
treated turf for fluopicolide, EPA is
confident that it has not underestimated
turf exposure due to the
conservativeness of the default turf
transfer value and conservative
assumptions in the short-term turf
assessment procedures (e.g., assuming
residues do not degrade over the thirtyday assessment period and assuming
high-end activities on turf for every day
of the assessment period). Therefore,
EPA is confident that it has not
underestimated postapplication
exposure of children as well as
incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by fluopicolide.
4. Conclusion regarding BAM. For
reasons explained in the Unit III.D.3.ii.
of the preamble to the final rule
published in the Federal Register of
August 27, 2008, EPA reduced the
FQPA safety factor for BAM to 1X for
inhalation and dermal exposure
scenarios and retained the 10X FQPA
safety factor for all other BAM exposure
scenarios. EPA is relying on the findings
in the preamble of the August 27, 2008
final rule and the 2008 BAM Risk
Assessment for the BAM FQPA safety
factor determinations for this action.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate exposure
estimates to the acute PAD (aPAD) and
chronic PAD (cPAD). For linear cancer
risks, EPA calculates the lifetime
E:\FR\FM\06AUR1.SGM
06AUR1
tkelley on DSK3SPTVN1PROD with RULES
45692
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
probability of acquiring cancer given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the appropriate
PODs to ensure that an adequate MOE
exists.
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. Therefore, fluopicolide is not
expected to pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to fluopicolide
from food and water will utilize 13% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. Based on the explanation in
Unit III.C.3., regarding residential use
patterns, chronic residential exposure to
residues of fluopicolide is not expected.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-term residential exposure plus
chronic exposure to food and water
(considered to be a background
exposure level). Fluopicolide is
currently registered for uses that could
result in short-term residential
exposure, and the Agency has
determined that it is appropriate to
aggregate average exposure through food
and water with short-term residential
exposures to fluopicolide.
Using the exposure assumptions
described in this unit for short-term
exposures, EPA has concluded the
combined short-term food, water, and
residential exposures result in aggregate
MOEs of 110 for adults and 180 for
children aged 6 to less than 11 years
old. Because EPA’s level of concern for
fluopicolide is a MOE of 100 or below,
these MOEs are not of concern.
4. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level). An
intermediate-term adverse effect was
identified; however, fluopicolide is not
registered for any use patterns that
would result in intermediate-term
residential exposure. Intermediate-term
risk is assessed based on intermediateterm residential exposure plus average
dietary exposure. Because there is no
intermediate-term residential exposure
and chronic dietary exposure has
already been assessed under the
appropriately protective cPAD (which is
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
at least as protective as the POD used to
assess intermediate-term risk), no
further assessment of intermediate-term
risk is necessary, and EPA relies on the
chronic dietary risk assessment for
evaluating intermediate-term risk for
fluopicolide.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
fluopicolide is not expected to pose a
cancer risk to humans.
6. BAM. As noted in Unit III.C., EPA
does not expect the increased tolerances
in this action to increase BAM exposure
above what was assessed in the June 19,
2008 BAM risk assessment. None of the
results of this BAM risk assessment
indicated a risk from aggregate BAM
exposures, including for acute and
chronic risks. Similarly, since short- and
intermediate-term aggregate MOEs for
BAM are greater than the LOC, they
represent risk estimates that are below
the Agency’s level of concern. Finally,
EPA has determined that BAM does not
pose an aggregate cancer risk for the
U.S. population. EPA has relied upon
the conclusions from the June 19, 2008
BAM Risk Assessment in order to make
these determinations.
7. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to fluopicolide
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology,
liquid chromatography/tandem mass
spectrometry (LC/MS/MS), is available
to enforce the tolerance expression.
The method may be requested from:
Chief, Analytical Chemistry Branch,
Environmental Science Center, 701
Mapes Rd., Ft. Meade, MD 20755–5350;
telephone number: (410) 305–2905;
email address: residuemethods@
epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
PO 00000
Frm 00020
Fmt 4700
Sfmt 4700
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has not established an
MRL for fluopicolide on the subject
commodities.
C. Response to Comments
EPA received one comment to the
Notice of Filing that made a request to
reconsider ‘‘loosening tolerances’’ for
several pesticide petitions, including for
fluopicolide. The commenter
additionally noted that, ‘‘It is an issue
of environmental justice that our
youngest citizens—our children—are
disproportionately exposed to health
risks.’’ The commenter points to an
American Academy of Pediatrics Policy
statement regarding pesticide exposure
in children, a Centers for Disease
Control and Prevention report on
human exposure to environmental
chemicals, and a President’s Cancer
Panel regarding reducing environmental
cancer risks in supporting the request to
reconsider the tolerance amendments
proposed for fluopicolide.
The Agency understands the
commenter’s concerns and recognizes
that some individuals believe that
certain pesticide chemicals should not
be permitted in our food, or that
pesticide tolerances should be
‘‘significantly tightened’’ as the
commenter notes. However, the existing
legal framework provided by section
408 of the FFDCA states that tolerances
may be set when EPA determines that
aggregate exposure to that pesticide is
safe, i.e., that there is a reasonable
certainty that no harm will result from
aggregate exposure to the pesticide
chemical residue. When making this
determination, EPA considers the
toxicity, including any potential
carcinogenicity, of the pesticide and all
anticipated dietary exposures and all
other exposures for which there is
reliable information. EPA also gives
special consideration to the potential
susceptibility and exposures of infants
and children to the pesticide chemical
residue when making this
determination. For fluopicolide, the
Agency has considered all the available
data, including all available data
concerning the potential for
carcinogenicity of fluopicolide and its
metabolites, and concluded after
conducting a risk assessment, that there
is a reasonable certainty that no harm
E:\FR\FM\06AUR1.SGM
06AUR1
45693
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
will result from aggregate human
exposure to fluopicolide and that,
accordingly, the amended fluopicolide
tolerances on potato, processed potato
waste and vegetable, tuberous and corm,
subgroup 1C, are safe.
D. Revisions to Petitioned-For
Tolerances
Based on the data supporting the
petition, EPA has determined that the
proposed tolerance in or on potato,
processed waste at 0.3 ppm should be
established at 1.0 ppm. That
determination was based on the
following: Processing data previously
provided for the use of fluopicolide on
potato indicate that residues of
fluopicolide concentrate in wet peels.
Residues of fluopicolide found in or on
potatoes are estimated to be in the range
of 0.2 ppm to 0.25 ppm following
directed soil application. Using the
highest estimated value of residues
found in or on potato and the theoretical
concentration factor of 4.0X for potato
processed waste (in accordance with
EPA’s Residue Chemistry Test
Guidelines), EPA has determined that a
tolerance of 1.0 ppm is appropriate for
residues on potato, processed waste.
Additionally, EPA has revised the
commodity terminology to potato,
processed potato waste in order to
reflect the preferred designation.

V. Conclusion
Therefore, tolerances are established
for residues of fluopicolide, 2,6dichloro-N-[[3-chloro-5(trifluoromethyl)-2pyridinyl]methyl]benzamide, in or on
potato, processed potato waste at 1.0
ppm; and vegetable, tuberous and corm,
subgroup 1C at 0.3 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this 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
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
subject to OMB approval under the
Paperwork Reduction Act (PRA) (44
U.S.C. 3501 et seq.), nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerances in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This 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 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 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) (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 of 1995
(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 May 23, 2014 (79 FR 29729) (FRL-9910-
29), 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
3F8191) by Valent U.S.A. Corporation, 1600 Riviera Avenue, Suite 200,
Walnut Creek, CA 94596. The petition requested that 40 CFR 180.627 be
amended by establishing tolerances for residues of the fungicide
fluopicolide, 2,6-dichloro-N-[[3-chloro-5-(trifluoromethyl)-2-
pyridinyl]methyl]benzamide, in or on potato, processed waste at 0.3
parts per million (ppm); and vegetable, tuberous and corm, subgroup 1C
at 0.3 ppm. That document referenced a summary of the petition prepared
by Valent U.S.A. Corporation, the registrant, which is available in the
docket, https://www.regulations.gov. Comments were received on the
notice of filing. EPA's response to these comments is discussed in Unit
IV.C.
Based upon review of the data supporting the petition, EPA has
revised the proposed tolerance in or on potato, processed waste from
0.3 ppm to 1.0 ppm, and has revised the commodity terminology. The
reasons for these changes are explained in Unit IV.D.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.''
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for fluopicolide including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with fluopicolide follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children.
Fluopicolide shares a metabolite, 2,6-dichlorobenzamide (BAM), with
another active ingredient, dichlobenil. Residues of BAM are considered
to be of regulatory concern, and separate toxicity data and endpoints
for risk assessment have been identified for
[[Page 45690]]
BAM. However, since increased tolerances on the commodities affected by
this action do not add significantly to the BAM dietary exposure, the
conclusions from the most recently conducted BAM human health risk
assessment remain unchanged.
The subchronic and chronic toxicity studies for fluopicolide showed
that the primary effects following exposure are in the liver. Kidney
and thyroid toxicity were observed in rats only. Fluopicolide is not
neurotoxic, carcinogenic, nor mutagenic. Developmental toxicity in the
rabbit occurred only at doses that caused severe maternal toxicity,
including death. In the rat, developmental effects were seen only at
high dose levels, in the presence of maternal toxicity. Similarly,
offspring effects (decreased body weight and body weight gain) in the
multi-generation reproductive toxicity study occurred only at levels
causing significant toxicity in parents. There is no evidence of
increased quantitative susceptibility of rat or rabbit fetuses to in
utero or postnatal exposure to fluopicolide. No toxic effects were
observed in studies in which fluopicolide was administered by the
dermal routes of exposure. The toxicological profile for fluopicolide
suggests that increased durations of exposure do not significantly
increase the severity of observed effects. Toxic effects observed in
the rabbit developmental and rat chronic/cancer studies were selected
as risk assessment endpoints for all durations of exposure.
Fluopicolide is classified as not likely to be carcinogenic to humans
and no quantification of cancer risks is required.
The toxicity profile for BAM has not changed since the last
assessment EPA conducted for BAM; an analysis of the toxicology profile
of BAM can be found in ``2,6-Dichlorobenzamide (BAM). 2,6-
Dichlorobenzamide (BAM) as a Metabolite/Degradate of Fluopicolide and
Dichlobenil. Human Health Risk Assessment for Proposed Uses of Rhubarb,
Dichlobenil on Caneberries (Subgroup 13-07A), and Bushberries (Subgroup
13-07B).'' dated June 19, 2008, in docket ID number EPA-HQ-OPP-2007-
0604.
Specific information on the studies received and the nature of the
adverse effects caused by fluopicolide as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in document: ``Fluopicolide and its Metabolite,
2,6-Dichlorobenzamide (BAEM). Human Health Risk Assessment to Support a
Petition for an Increased Tolerance on Tuberous and Corm Subgroup 1C
Vegetables,'' pp. 31-35 in docket ID number EPA-HQ-OPP-2014-0225.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for fluopicolide and BAM
used for human risk assessment is discussed in Unit III.B. of the final
rule published in the Federal Register of April 20, 2011 (76 FR 22045)
(FRL-8859-9).
C. Exposure Assessment
The fluopicolide exposure assessment considers exposure from
fluopicolide only. EPA did not reassess exposures from BAM since the
proposed change in use pattern does not add significantly to the BAM
dietary exposure, and residues of BAM due to fluopicolide applications
are significantly lower than those from dichlobenil applications. EPA
is relying on conclusions from the 2008 BAM Human Health Risk
Assessment, which remain unchanged. A discussion of how BAM exposures
were assessed can be found in Unit III.C. of the final rule published
in the Federal Register of August 27, 2008 (73 FR 50563) (FRL-8377-7).
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to fluopicolide, EPA considered exposure under the petitioned-
for tolerances as well as all existing fluopicolide tolerances in 40
CFR 180.627. EPA assessed dietary exposures from fluopicolide 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 fluopicolide; 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
Food Commodity Intake Database (DEEM-FCID) Version 3.16. This software
uses 2003-2008 food consumption data from the U.S. Department of
Agriculture's (USDA's) National Health and Nutrition Examination
Survey, What We Eat in America (NHANES/WWEIA). As to residue levels in
food, EPA assumed 100 percent crop treated (PCT) and tolerance-level
residues. iii. Cancer. Based on the data summarized in Unit III.A., EPA
has concluded that fluopicolide does not pose a cancer risk to humans.
Therefore, a quantitative dietary exposure assessment for the purpose
of assessing cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue and/or PCT information in the dietary assessment
for fluopicolide. Tolerance level residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for fluopicolide in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of fluopicolide. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on the surface water concentrations estimated using the
Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/
EXAMS); and Screening Concentrations in Ground Water (SCI-GROW) models,
the estimated environmental concentrations (EECs) of fluopicolide for
chronic exposure (non-cancer) assessments are estimated to be 24.14
[[Page 45691]]
ppb for surface water and 0.5 ppb for ground water. Acute and cancer
dietary risks were not quantified, as previously discussed.
3. From non-dietary exposure. i. 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).
ii. Fluopicolide is currently registered for the use on residential
turf grass, recreational sites, and ornamental plants that could result
in short-term residential exposures. EPA assessed residential exposure
using the following assumptions:
a. Residential handler short-term dermal and inhalation exposures
to fluopicolide when mixing, loading, and applying the formulations.
b. Residential post-application exposures via the dermal route for
adults and children entering treated lawns or treated gardens and
during mowing and golfing activities. and
c. Incidental non-dietary ingestion (i.e., hand-to-mouth, object-
to-mouth, and soil ingestion) by children during post-application
activities on treated turf.
Further information regarding EPA standard assumptions and generic
inputs for residential exposures may be found at https://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
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 fluopicolide and any other
substances. Although fluopicolide shares a common metabolite, BAM, with
dichlobenil, quantification of risks for residues of BAM resulting from
fluopicolide was not done as part of this assessment because they
contribute an insignificant amount to the total BAM exposure.
Furthermore, aggregate risks to BAM are not of concern. For the
purposes of this tolerance action, EPA has not assumed that
fluopicolide 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 Web site at:
https://www.epa.gov/pesticides/cumulative/.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the FQPA Safety
Factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional safety factor when
reliable data available to EPA support the choice of a different
factor.
2. Prenatal and postnatal sensitivity. There is no evidence of
quantitative susceptibility following in utero and/or postnatal
fluopicolide exposure in the rabbit and rat developmental toxicity
studies or in the 2-generation rat reproduction study. Qualitative
susceptibility was observed in the rat developmental toxicity study. In
this study, fetal effects (reduced growth and skeletal defects) and
late-term abortions were observed at doses at which only decreased body
weight gain were observed in maternal animals. There is low concern for
this qualitative susceptibility because the fetal effects and late-term
abortions have been well characterized and only occurred at a dose
level near the limit dose. Protection for the maternal effects also
protects for any effects that may occur during development. There are
no residual uncertainties concerning prenatal and postnatal toxicity
for fluopicolide.
3. Conclusion regarding fluopicolide. EPA has determined that
reliable data show the safety of infants and children would be
adequately protected if the FQPA SF were reduced to 1X. That decision
is based on the following findings:
i. The toxicity database for fluopicolide is complete.
ii. There is no indication that fluopicolide is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is no evidence that fluopicolide results in increased
susceptibility in in utero rabbits in the prenatal developmental
studies or in young rats in the 2-generation reproduction study.
Although there was some evidence of qualitative susceptibility in the
rat developmental toxicity study, as discussed in Unit III.D.2., the
degree of concern for the prenatal and/or postnatal toxicity is low;
thus, there is no need for the 10X FQPA safety factor to account for
potential prenatal or postnatal toxicity.
iv. There are no residual uncertainties identified in the exposure
databases. The chronic dietary food exposure assessments were performed
based on 100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to fluopicolide in drinking water. Although EPA has
required additional data on transferable residues from treated turf for
fluopicolide, EPA is confident that it has not underestimated turf
exposure due to the conservativeness of the default turf transfer value
and conservative assumptions in the short-term turf assessment
procedures (e.g., assuming residues do not degrade over the thirty-day
assessment period and assuming high-end activities on turf for every
day of the assessment period). Therefore, EPA is confident that it has
not underestimated postapplication exposure of children as well as
incidental oral exposure of toddlers. These assessments will not
underestimate the exposure and risks posed by fluopicolide.
4. Conclusion regarding BAM. For reasons explained in the Unit
III.D.3.ii. of the preamble to the final rule published in the Federal
Register of August 27, 2008, EPA reduced the FQPA safety factor for BAM
to 1X for inhalation and dermal exposure scenarios and retained the 10X
FQPA safety factor for all other BAM exposure scenarios. EPA is relying
on the findings in the preamble of the August 27, 2008 final rule and
the 2008 BAM Risk Assessment for the BAM FQPA safety factor
determinations for this action.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime
[[Page 45692]]
probability of acquiring cancer given the estimated aggregate exposure.
Short-, intermediate-, and chronic-term risks are evaluated by
comparing the estimated aggregate food, water, and residential exposure
to the appropriate PODs to ensure that an adequate MOE exists.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effect resulting from a single oral exposure
was identified and no acute dietary endpoint was selected. Therefore,
fluopicolide is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
fluopicolide from food and water will utilize 13% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure. Based on the explanation in Unit III.C.3., regarding
residential use patterns, chronic residential exposure to residues of
fluopicolide is not expected.
3. Short-term risk. Short-term aggregate exposure takes into
account short-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level). Fluopicolide
is currently registered for uses that could result in short-term
residential exposure, and the Agency has determined that it is
appropriate to aggregate average exposure through food and water with
short-term residential exposures to fluopicolide.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures result in aggregate MOEs of 110 for adults
and 180 for children aged 6 to less than 11 years old. Because EPA's
level of concern for fluopicolide is a MOE of 100 or below, these MOEs
are not of concern.
4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account intermediate-term residential exposure plus chronic
exposure to food and water (considered to be a background exposure
level). An intermediate-term adverse effect was identified; however,
fluopicolide is not registered for any use patterns that would result
in intermediate-term residential exposure. Intermediate-term risk is
assessed based on intermediate-term residential exposure plus average
dietary exposure. Because there is no intermediate-term residential
exposure and chronic dietary exposure has already been assessed under
the appropriately protective cPAD (which is at least as protective as
the POD used to assess intermediate-term risk), no further assessment
of intermediate-term risk is necessary, and EPA relies on the chronic
dietary risk assessment for evaluating intermediate-term risk for
fluopicolide.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, fluopicolide is not expected to pose a cancer risk to humans.
6. BAM. As noted in Unit III.C., EPA does not expect the increased
tolerances in this action to increase BAM exposure above what was
assessed in the June 19, 2008 BAM risk assessment. None of the results
of this BAM risk assessment indicated a risk from aggregate BAM
exposures, including for acute and chronic risks. Similarly, since
short- and intermediate-term aggregate MOEs for BAM are greater than
the LOC, they represent risk estimates that are below the Agency's
level of concern. Finally, EPA has determined that BAM does not pose an
aggregate cancer risk for the U.S. population. EPA has relied upon the
conclusions from the June 19, 2008 BAM Risk Assessment in order to make
these determinations.
7. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to fluopicolide residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology, liquid chromatography/tandem mass
spectrometry (LC/MS/MS), is available to enforce the tolerance
expression.
The method may be requested from: Chief, Analytical Chemistry
Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD
20755-5350; telephone number: (410) 305-2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has not established an MRL for fluopicolide on the
subject commodities.
C. Response to Comments
EPA received one comment to the Notice of Filing that made a
request to reconsider ``loosening tolerances'' for several pesticide
petitions, including for fluopicolide. The commenter additionally noted
that, ``It is an issue of environmental justice that our youngest
citizens--our children--are disproportionately exposed to health
risks.'' The commenter points to an American Academy of Pediatrics
Policy statement regarding pesticide exposure in children, a Centers
for Disease Control and Prevention report on human exposure to
environmental chemicals, and a President's Cancer Panel regarding
reducing environmental cancer risks in supporting the request to
reconsider the tolerance amendments proposed for fluopicolide.
The Agency understands the commenter's concerns and recognizes that
some individuals believe that certain pesticide chemicals should not be
permitted in our food, or that pesticide tolerances should be
``significantly tightened'' as the commenter notes. However, the
existing legal framework provided by section 408 of the FFDCA states
that tolerances may be set when EPA determines that aggregate exposure
to that pesticide is safe, i.e., that there is a reasonable certainty
that no harm will result from aggregate exposure to the pesticide
chemical residue. When making this determination, EPA considers the
toxicity, including any potential carcinogenicity, of the pesticide and
all anticipated dietary exposures and all other exposures for which
there is reliable information. EPA also gives special consideration to
the potential susceptibility and exposures of infants and children to
the pesticide chemical residue when making this determination. For
fluopicolide, the Agency has considered all the available data,
including all available data concerning the potential for
carcinogenicity of fluopicolide and its metabolites, and concluded
after conducting a risk assessment, that there is a reasonable
certainty that no harm
[[Page 45693]]
will result from aggregate human exposure to fluopicolide and that,
accordingly, the amended fluopicolide tolerances on potato, processed
potato waste and vegetable, tuberous and corm, subgroup 1C, are safe.
D. Revisions to Petitioned-For Tolerances
Based on the data supporting the petition, EPA has determined that
the proposed tolerance in or on potato, processed waste at 0.3 ppm
should be established at 1.0 ppm. That determination was based on the
following: Processing data previously provided for the use of
fluopicolide on potato indicate that residues of fluopicolide
concentrate in wet peels. Residues of fluopicolide found in or on
potatoes are estimated to be in the range of 0.2 ppm to 0.25 ppm
following directed soil application. Using the highest estimated value
of residues found in or on potato and the theoretical concentration
factor of 4.0X for potato processed waste (in accordance with EPA's
Residue Chemistry Test Guidelines), EPA has determined that a tolerance
of 1.0 ppm is appropriate for residues on potato, processed waste.
Additionally, EPA has revised the commodity terminology to potato,
processed potato waste in order to reflect the preferred designation.
V. Conclusion
Therefore, tolerances are established for residues of fluopicolide,
2,6-dichloro-N-[[3-chloro-5-(trifluoromethyl)-2-
pyridinyl]methyl]benzamide, in or on potato, processed potato waste at
1.0 ppm; and vegetable, tuberous and corm, subgroup 1C at 0.3 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA section 408(d)
in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this 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 require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under FFDCA section 408(d), such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This 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 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 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) (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 of 1995 (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).
