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

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).

In the Federal Register of Wednesday,
July 6, 2011 (76 FR 39358) (FRL–8875–

FFDCA section 408(d)(3), 21 U.S.C.
PO 00000
Frm 00022
Fmt 4700
Sfmt 4700
346a(d)(3), announcing the filing of a
pesticide petition (PP1E7847) by the
Interregional Research Project Number 4
(IR–4), IR–4 Project Headquarters, 500
College Road East, Suite 201W,
Princeton, NJ 08540. The petition
requested that 40 CFR 180.572 be
amended by establishing tolerances for
residues of bifenazate: Hydrazine
carboxylic acid, 2-(4-methoxy-[1,1’biphenyl]-3-yl)-methylethyl ester in or
on fruit, pome, group 11–10 at 0.75
parts per million (ppm); herb, subgroup
19A dried leaves, except chervil, dried
and chive, dried, at 140 ppm; herb,
subgroup 19A, fresh leaves at 30 ppm;
timothy, forage at 140 ppm; timothy,
hay at 120 ppm; and vegetable, fruiting,
group 8–10 at 2.0 ppm. That document
referenced a summary of the petition
prepared by Chemtura Corporation, the
registrant, which is available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
Based upon review of the data
supporting the petition, EPA has revised
the proposed tolerance level and
corrected the commodity definition for
certain commodities, and revised the
tolerance expression for bifenazate. The
reasons for these changes are explained
in Unit IV.C.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’
Consistent with FFDCA section
408(b)(2)(D), and the factors specified 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
E:\FR\FM\06AUR1.SGM
06AUR1
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
aggregate exposure for bifenazate
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with bifenazate follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered their
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.
Bifenazate has low acute toxicity for
the oral, dermal and inhalation routes of
exposure. For subchronic oral
exposures, the dog is the most sensitive
species. For chronic oral exposures, the
dog and the rat are equally sensitive.
Subchronic and chronic studies in
rats and dogs indicate that the liver and
hematopoietic system (spleen and bone
marrow with associated hematological
findings) are the primary target organs
in these species. Additional toxicity was
seen in the kidney (dogs following
chronic exposure) and adrenal cortex
(male rats following subchronic
exposure). Decreases in body weight,
body-weight gain, and food
consumption were also associated with
liver and hematopoietic system toxicity
in several studies.
In the rat developmental toxicity
study, the maternal effects consisted of
clinical signs of toxicity, decreased body
weight and body-weight gains, and
reduced food consumption at the middose. Increases in early fetal resorptions
occurred at the same doses that caused
maternal toxicity. In the rabbit
developmental toxicity study, there
were no maternal or developmental
effects up to the highest dose tested
(HDT). In the 2-generation rat
reproduction study, the parental effects
occurred at the mid-dose and consisted
of decreased body weight and body-
weight gains. There were no
reproductive or offspring effects up to
the HDT.
In the acute neurotoxicity study,
treatment related effects were seen only
at the HDT, and consisted of decreased
motor activity (rearing in females; center
time in both sexes). In the subchronic
neurotoxicity study, effects were also
only seen at the HDT (34.5 milligrams/
kilogram/day (mg/kg/day) and consisted
of decreased landing foot splay (males),
decreased fore- and hindlimb grip
strength (males), decreased motor
activity measurements consisting of
center times (females) and rearing
activity (both sexes). The level of
concern (LOC) for neurotoxicity in the
bifenazate database is low however
because;
• The observed effects are well
characterized;
• They occur only at the highest
doses tested; and
• They are protected for by the
studies used in the endpoint selection.
There were no observed toxicological
effects in the immunotoxicity study up
to the HDT.
In the mouse carcinogenicity study,
males and females were tested up to 225
ppm and 175 ppm, respectively, which
elicited decreased body weight and
body-weight gains in females. In male
mice, there was an increase in the
incidence of liver adenomas only,
which was not considered statistically
significant by pair-wise comparison.
There also was no progression of the
adenomas to carcinomas in males in this
study. A full battery of mutagenicity
studies were negative for mutagenic or
clastogenic activity. Bifenazate is
classified as ‘‘not likely’’ to be
carcinogenic to humans.
Specific information on the studies
received and the nature of the adverse
effects caused by bifenazate as well as
the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://

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.

endpoints for bifenazate used for human
risk assessment is shown in the Table of

Human Equivalent Dose (HED). HED’s route-to-route extrapolation converts human and animal values from mg/L concentrations to mg/kg oralequivalent doses. The equation uses a single conversion factor to account for default body weights and respiratory volumes. An activity factor is
used to account for increased exposure resulting from increased respiration. Using the HEC calculated (based upon terminal airway inflammation
in males), a conversion of the inhalation concentration to a dose (mg/L to mg/kg/day) was conducted as follows:
• Human-Equivalent Dose (HED, mg/kg/day) = Dose (systemic HEC value, mg/L) × A × CF (L/hr/kg) × D (hours) × AF = mg/kg
Where: A = absorption: Ratio of deposition and absorption in respiratory tract compared to absorption by the oral route. CF = conversion Factor; a L/hr/kg factor which accounts for respiratory volume and body weight for a given species and strain. D = duration; duration of daily animal
or human exposure (hours). AF = activity Factor; animal default is 1. The residential human equivalent dose for bifenazate is calculated as follows:
• Residential HED: (0.0009 mg/L) × 1 × 6 × 8 × 1 = 0.135 mg/kg/day.

C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to bifenazate, EPA considered
exposure under the petitioned-for
tolerances as well as all existing
bifenazate tolerances in 40 CFR 180.572.
EPA assessed dietary exposures from
bifenazate in food as follows:
i. Acute exposure. In conducting the
acute dietary exposure assessment EPA
used the Dietary Exposure Evaluation
Model—Food Consumption Intake
Database (DEEM–FCID, ver. 3.16),
which incorporates consumption
information from the United States
Department of Agriculture’s (USDA’s)
National Health and Nutrition
Examination Survey, What We Eat in
America, (NHANES/WWEIA). This
dietary survey was conducted from 2003
to 2008.
As to residue levels in food, the acute
analysis for the general population,
including infants and children, was
unrefined and used tolerance-level
residues and 100 PCT. The acute
analysis for females 13 to 49 years old
was highly refined and incorporated
data from the USDA’s Pesticide Data
Program (PDP), crop field trial data, and
PCT estimates. DEEM (ver. 7.81) default
processing factors were assumed for all
commodities excluding apple juice,
grape juice, and wine/sherry. The
processing factors for these commodities
were reduced to 1.0, based on data from
processing studies.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the DEEM–FCID, ver. 3–16
which incorporates consumption
information from the USDA NHANES/
WWEIA; 2003–2008. As to residue
levels in food, the chronic dietary
exposure analysis for all population
subgroups was partially refined and
used tolerance-level residues and PCT
estimates. DEEM default processing
factors were assumed for all
commodities excluding apple juice,
grape juice, and wine/sherry. The
processing factors for these commodities
were reduced to 1.0 based on data from
processing studies.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
classified bifenazate as ‘‘not likely’’ to
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
be a human carcinogen. Therefore, a
dietary exposure assessment for the
purpose of assessing cancer risk was not
conducted.
iv. Anticipated residue and percent
crop treated (PCT) information. Section
408(b)(2)(E) of FFDCA authorizes EPA
to use available data and information on
the anticipated residue levels of
pesticide residues in food and the actual
levels of pesticide residues that have
been measured in food. If EPA relies on
such information, EPA must require
pursuant to FFDCA section 408(f)(1)
that data be provided 5 years after the
tolerance is established, modified, or
left in effect, demonstrating that the
levels in food are not above the levels
anticipated. For the present action, EPA
will issue such data call-ins as are
required by FFDCA section 408(b)(2)(E)
and authorized under FFDCA section
408(f)(1). Data will be required to be
submitted no later than 5 years from the
date of issuance of these tolerances.
Section 408(b)(2)(F) of FFDCA states
that the Agency may use data on the
actual percent of food treated for
assessing chronic dietary risk only if:
• Condition a: The data used are
reliable and provide a valid basis to
show what percentage of the food
derived from such crop is likely to
contain the pesticide residue.
• Condition b: The exposure estimate
does not underestimate exposure for any
significant subpopulation group.
• Condition c: Data are available on
pesticide use and food consumption in
a particular area, the exposure estimate
does not understate exposure for the
population in such area.
In addition, the Agency must provide
for periodic evaluation of any estimates
used. To provide for the periodic
evaluation of the estimate of PCT as
required by FFDCA section 408(b)(2)(F),
EPA may require registrants to submit
data on PCT.
The Agency used PCT information as
follows:
Maximum PCT estimates were used in
the acute dietary risk assessment:
Almonds: 10%; apples: 5%; apricots:
10%; beans, green: 2.5%; caneberries:
30%; cantaloupes: 2.5%; cherries: 5%;
cucumbers: 5%; grapefruit: 5%; grapes:
20%; nectarines: 10%; oranges: 2.5%;
peaches: 20%; pears: 30%; pecans:
PO 00000
Frm 00025
Fmt 4700
Sfmt 4700
2.5%; peppers: 10%; pistachios: 2.5%;
plums/prunes: 20%; potatoes: 5%;
pumpkins: 5%; squash: 2.5%;
strawberries: 65%; tomatoes: 10%;
walnuts: 5%; and watermelon: 2.5%.
The following average PCT estimates
were used in the chronic dietary risk
assessment: Almonds: 5%; apples: 5%;
apricots: 5%; beans, green: 1%;
caneberries: 25%; cantaloupes: 1%;
cherries: 2.5%; cucumbers: 2.5%;
grapefruit: 5%; grapes: 10%; nectarines:
5%; oranges: 1%; peaches: 10%; pears:
15%; pecans: 1%; peppers: 5%;
pistachios: 2.5%; plums/prunes: 5%;
potatoes: 5%; pumpkins: 2.5%; squash:
1%; strawberries: 45%; tomatoes: 5%;
walnuts: 2.5%; and watermelon: 1%.
In most cases, EPA uses available data
from USDA/National Agricultural
Statistics Service (USDA/NASS),
proprietary market surveys, and the
National Pesticide Use Database for the
chemical/crop combination for the most
recent 6–7 years. EPA uses an average
PCT for chronic dietary risk analysis.
The average PCT figure for each existing
use is derived by combining available
public and private market survey data
for that use, averaging across all
observations, and rounding to the
nearest 5%, except for those situations
in which the average PCT is less than
one. In those cases, 1% is used as the
average PCT and 2.5% is used as the
maximum PCT. EPA uses a maximum
PCT for acute dietary risk analysis. The
maximum PCT figure is the highest
observed maximum value reported
within the recent 6 years of available
public and private market survey data
for the existing use and rounded up to
the nearest multiple of 5%.
The Agency believes that the three
conditions discussed in Unit III.C.1.iv.
have been met. With respect to
Condition a, PCT estimates are derived
from Federal and private market survey
data, which are reliable and have a valid
basis. The Agency is reasonably certain
that the percentage of the food treated
is not likely to be an underestimation.
As to Conditions b and c, regional
consumption information and
consumption information for significant
subpopulations is taken into account
through EPA’s computer-based model
for evaluating the exposure of
significant subpopulations including
E:\FR\FM\06AUR1.SGM
06AUR1
tkelley on DSK3SPTVN1PROD with RULES
45698
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
several regional groups. Use of this
consumption information in EPA’s risk
assessment process ensures that EPA’s
exposure estimate does not understate
exposure for any significant
subpopulation group and allows the
Agency to be reasonably certain that no
regional population is exposed to
residue levels higher than those
estimated by the Agency. Other than the
data available through national food
consumption surveys, EPA does not
have available reliable information on
the regional consumption of food to
which bifenazate may be applied in a
particular area.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for bifenazate in drinking water. These
simulation models take into account
data on the physical, chemical, and fate/
transport characteristics of bifenazate.
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 First Index Reservoir
Screening Tool (FIRST) model and the
dry bean application scenario (highest
registered/proposed use rate) and the
Screening Concentrations in Ground
Water (SCI–GROW) model, the
estimated drinking water concentrations
(EDWCs) of bifenazate acute exposures
are estimated to be 37.3 ppb for surface
water and 0.014 ppb for ground water.
For chronic exposures for non-cancer
assessments are estimated to be 11.2
ppb for surface water and 0.014 ppb for
ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model.
For acute dietary risk assessment, the
water concentration value of 37.3 ppb
was used to assess the contribution to
drinking water.
For chronic dietary risk assessment,
the water concentration of value 11.2
ppb was used to assess the contribution
to drinking 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).
Bifenazate is currently registered for
the following uses that could result in
residential exposures: Ornamental
plants, including bedding plants,
flowering plants, foliage plants, bulb
crops perennials, trees, and shrubs. EPA
assessed residential exposure using the
following assumptions: There is a
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
potential for short-term dermal and
inhalation exposures by homeowners
applying bifenazate. Intermediate-term
exposures are not likely because of the
intermittent nature of applications by
homeowners.
The residential handler exposure
assessment estimates dermal and
inhalation exposures for individuals
using bifenazate on residential
ornamentals. The quantitative exposure/
risk assessment developed for
residential handlers is based on the
following scenarios:
i. Mixing/loading/applying liquids
with manually-pressurized handwand,
ii. Mixing/loading/applying liquids
with hose-end sprayer,
iii. Mixing/loading/applying liquids
with backpack, and
iv. Mixing/loading/applying liquids
with sprinkler can.
Unit exposure values and estimates
for area treated were taken from the
2012 Residential SOPs: Gardens and
Trees. An aggregate risk index (ARI) was
used since the LOCs for dermal
exposure (100) and inhalation exposure
(30) are different. The target ARI is 1;
therefore, ARIs of less than 1 result in
risk estimates of concern. The ARI was
calculated as follows.
• Aggregate Risk Index (ARI) = 1 ÷
[(Dermal LOC ÷ Dermal MOE) +
(Inhalation LOC ÷ Inhalation MOE)]
Short-term risk estimates for
residential handlers are greatest for
exposure scenarios ‘‘hose-end sprayer’’
and ‘‘backpack’’ resulting in ARIs of 80
and 66, respectively. Short-term dermal
and inhalation risk estimates to
residential handlers do not exceed
EPA’s LOC for all scenarios. All the
ARIs are above 1 and do not exceed the
Agency’s LOC for all scenarios.
Short-term dermal exposure and risk
from residential post-application have
been assessed for bifenazate under the
following scenarios, routes of exposure
and lifestages:
• Gardens and Trees: adults (dermal)
and children 6 to less than or equal 11
years old (dermal).
These lifestages are not the only
lifestages that could be potentially
exposed for these post-application
scenarios; however, the assessment of
these lifestages is health protective for
the exposures and risks for any other
potentially exposed lifestages. All adult
and children dermal post-application
risk estimates for exposure to treated
trees and gardens are not of concern
(MOEs ≥ 100). Details of assumptions
and factors the Agency applied in
residential and residential postapplication exposure assessments are
detailed in the 2012 Residential SOPs at

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.’’
EPA has not found bifenazate to share
a common mechanism of toxicity with
any other substances, and bifenazate
does not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that bifenazate does not have
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 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 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.
The prenatal and postnatal toxicology
database for bifenazate includes rat and
rabbit developmental toxicity studies
and a 2-generation reproduction toxicity
study in rats. In the rat developmental
toxicity study, the maternal effects
consisted of clinical signs of toxicity,
decreased body weight and body-weight
gains, and reduced food consumption at
the mid-dose. Increases in early fetal
resorptions occurred at the same doses
that caused maternal toxicity. In the
E:\FR\FM\06AUR1.SGM
06AUR1
tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
rabbit developmental toxicity study,
there were no maternal or
developmental effects up to the HDT. In
the 2-generation rat reproduction study,
the parental effects occurred at the middose and consisted of decreased body
weight and body-weight gains. There
were no reproductive or offspring effects
up to the HDT.
3. Conclusion. 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 bifenazate
is complete.
ii. There is evidence of neurotoxicity
in the bifenazate database. The level of
concern for neurotoxic effects in
children is low however because
• The observed effects are well
characterized;
• They occur only at the highest
doses tested; and
• They are protected for by the
studies used in the endpoint selection.
iii. There is no evidence that
bifenazate results in increased
susceptibility in in utero rats or rabbits
in the pre- or postnatal developmental
studies or in young rats in the 2generation reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The exposure databases are sufficient to
determine the nature and magnitude of
the residue in food and water. For acute
exposure for the general population and
chronic exposure, the dietary exposure
analyses are unlikely to underestimate
exposure as they incorporated tolerancelevel residues, 100 PCT for acute
exposure, PCT for chronic exposure,
and modeled drinking water estimates.
For acute analysis for females 13 to 49
years, the dietary analysis is unlikely to
underestimate exposure as PDP, crop
field trial data, PCT estimates and
modeled drinking water estimates were
utilized.
EPA made conservative (protective)
assumptions in the ground water and
surface water modeling used to assess
exposure to bifenazate in drinking
water. The dietary food and drinking
water exposure assessments will not
underestimate the potential exposures
for infants and children. The residential
use (ornamentals) is not expected to
result in post-application exposure to
infants and children as well as
incidental oral exposure of toddlers.
The post-application exposure
assessments are based upon the
residential SOPs, which are based upon
reasonable worst-case assumptions and
are not expected to underestimate risk.
These assessments will not
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
underestimate the exposure and risks
posed by bifenazate.
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 aPAD and cPAD. For
linear cancer risks, EPA calculates the
lifetime 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. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
bifenazate will occupy <1.9% of the
aPAD for children 1 to 2 years old, the
population group receiving the greatest
exposure. The acute dietary exposure
estimates are not of concern to EPA
(<100% aPAD) for the general U.S.
population and all population
subgroups
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to bifenazate from
food and water will utilize 74% of the
cPAD for children 1 to 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 bifenazate is not expected.
3. Short- and intermediate-term risks.
Short- and intermediate-term aggregate
exposures take into account short- and
intermediate-term residential exposures
plus chronic exposure to food and water
(considered to be a background
exposure level). Bifenazate is currently
registered for uses that could result in
short- and intermediate-term residential
exposures.
The short- and intermediate-term
toxicological PODs for bifenazate are the
same for each route of exposure.
Therefore, for residential exposure
scenarios, only short-term exposures
were assessed, and are considered to be
protective of intermediate-term
exposure and risk.
It was appropriate to aggregate
postapplication dermal exposures with
dietary (food and water) exposures. The
dermal postapplication exposure to
gardens and ornamentals scenario is the
residential exposure scenario with the
greatest risk estimate for both adults and
children 6 ≤ 11 years old; therefore, the
exposure estimates for this scenario are
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700
45699
protective of any other exposure
scenarios.
For the adult and children 6 ≤ 11
years old short- and intermediate-term
aggregate risk assessment, the MOE
approach was used to estimate aggregate
exposures as there are different PODs
for oral and dermal routes of exposure
but the LOC are the same. The chronic
dietary exposure estimate for Adults 20–
49 years old and Children 6–12 years
old were used in the aggregate risk
estimate for adults and children 6 ≤ 11
years old, respectively.
All of the adult and children 6 ≤ 11
years old chronic dietary + dermal
aggregate risk estimates do not exceed
EPA’s LOC (MOEs ≥ 100).
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
bifenazate (classified as ‘‘not likely’’ to
be a human carcinogen) is therefore not
expected to pose a cancer risk to
humans.
5. 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 bifenazate
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies
are available to enforce the tolerance
expression.
For plant commodities, highperformance liquid chromatography
with oxidative coulometric
electrochemical detector (HPLC/ELCD)
Method UCC–D2341 is available as a
primary enforcement method for the
combined residues of bifenazate and its
metabolite D3598. The method has been
forwarded to the United States Food and
Drug Administration (FDA) for
inclusion in the Pesticides Analytical
Manual, Volume II (PAM II). The limit
of quantification (LOQ) and limit of
detection (LOD) of Method UCC–D2341
are 0.01 and 0.005 ppm, respectively. In
addition, a liquid chromatographic
system with tandem mass spectrometers
(LC–MS/MS) method (NCL ME 245) was
recently submitted as a confirmatory
method and has been forwarded to FDA.
For livestock commodities, HPLC
methods with fluorescence detection or
ELCD are available as primary methods
for the enforcement of tolerances for
residues of bifenazate and its regulated
metabolites in livestock matrices. The
methods have undergone a successful
validation by the Agency and have been
forwarded to FDA for inclusion in PAM

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.
There are currently no established
Codex MRLs for bifenazate in/on herbs,
and timothy forage and hay. Codex
MRLs are established for pome fruits
(0.7 ppm), chili peppers (3 ppm), sweet
peppers (2 ppm) and tomato (0.5 ppm),
but not for other members of Vegetable,
fruiting, group 8–10.
The U.S. is establishing a tolerance for
Vegetable, fruiting, group 8–10 at 4.0
ppm for residues of bifenazate (and its
metabolite). There is an existing U.S.
tolerance of 2 ppm for Vegetables,
fruiting, crop, group 8. This tolerance
was established in 2003 prior to the
implementation of the Organization for
Economic Co-Operation and
Development (OECD) calculation
procedures. In 2007 Codex established
the MRLs for chili peppers, sweet
peppers and tomato and relied on the
U.S. field trial data. Codex chose not to
establish a group tolerance for the
fruiting vegetables but instead
established separate Codex MRLs for
tomato, peppers and chili peppers using
the highest observed residue approach.
The approach taken by Codex is not in
line with how the U.S. establishes crop
group tolerances. Further, using the
VerDate Mar<15>2010
15:45 Aug 05, 2014
Jkt 232001
OECD calculation procedures and based
on data from bell and non-bell pepper
studies conducted in the U.S., and
tomato studies conducted in Canada
and the U.S. results in the
recommended tolerance of 4.0 ppm.
EPA is establishing the U.S. tolerance
for residue in or on pome fruit at 0.7
ppm, in harmonization with the
established Codex MRL.
C. Revisions to Petitioned-For
Tolerances
After reviewing supporting data and
information, EPA modified certain
elements of the petition as proposed in
the notice of filing, as follows:
1. EPA corrected the proposed
commodity definitions, ‘‘Herb, subgroup
19A, fresh leaves’’ and ‘‘Herb, subgroup
19A, dried leaves, except chervil, dried
and chive, dried’’ to read ‘‘Herb
subgroup 19A, except chervil and
chive’’ to specify crop coverage and for
accuracy and consistency in naming of
commodities.
2. Using the OECD tolerancecalculation procedures, the Agency
modified proposed tolerance levels for
certain commodities as follows:
i. A proposed tolerance at 140 ppm
for ‘‘Herb, subgroup 19A, dried leaves,
except chervil, dried and chive, dried’’
was established for ‘‘Herb, subgroup
19A, except chervil and chive’’ at 300
ppm, and
ii. A proposed tolerance at 140 ppm
on timothy, forage, was established at
200 ppm (tolerance with regional
registrations), and a proposed tolerance
of 120 ppm on timothy, hay, was
established at 150 ppm (tolerance with
regional registrations).
3. As petitioned-for, EPA is
establishing tolerances with regional
registrations for timothy, forage and
timothy, hay for regional use in two
counties, Eureka and Humboldt, in the
State of Nevada. Applications of
bifenazate can only be made to timothy
that is intended for use as horse feed.
Livestock feedstuffs are not derived
from the proposed crops of the subject
petition, except for timothy. The Agency
is removing existing time-limited
tolerances established for bifenazate
under section 18 emergency exemptions
for timothy, forage and timothy, hay at
50 ppm and 150 ppm, respectively, as
they are superseded by this action.
4. As previously stated, the U.S.
tolerance for Vegetable, fruiting, group
8–10 is being changed to 4.0 ppm. This
is based the use of the OECD calculation
procedures on data from bell and nonbell pepper studies conducted in the
United States, and tomato studies
conducted in Canada and the United
States.
PO 00000
Frm 00028
Fmt 4700
Sfmt 4700
In addition, the Agency is revising the
tolerance expressions for bifenazate
tolerances in order to conform to current
EPA policy as follows:
5. 40 CFR § 180.572(a)(1) is revised to
read as follows: Tolerances are
established for residues of bifenazate (1methylethyl 2-(4-methoxy[1,1′biphenyl]-3-yl)hydrazinecarboxylate)
including its metabolites and
degradates, in or on the commodities
listed in the following table.
Compliance with the tolerance levels
specified are to be determined by
measuring only the sum of bifenazate
and its metabolite, diazinecarboxylic
acid, 2-(4-methoxy-[1,1’-biphenyl]-3-yl),
1-methylethyl ester, (calculated as the
stoichiometric equivalent of bifenazate)
in or on food commodities, and
6. The tolerance expression for 40
CFR § 180.572(a)(2) is modified as
follows: Tolerances are established for
residues of bifenazate (1-methylethyl 2(4-methoxy[1,1′-biphenyl]-3-yl)
hydrazinecarboxylate) including its
metabolites and degradates, in or on the
commodities listed in the following
table. Compliance with the tolerance
levels specified are to be determined by
measuring only the sum of bifenazate
and its metabolites diazinecarboxylic
acid, 2-(4-methoxy-[1,1′-biphenyl]-3-yl),
1-methylethyl ester; 1,1′-biphenyl, 4-ol;
and 1,1′-biphenyl, 4-oxysulfonic acid
(calculated as the stoichiometric
equivalent of bifenazate) in or on food
commodities.
V. Conclusion
Therefore, tolerances are established
for residues of bifenazate (1-methylethyl
2-(4-methoxy[1,1′-biphenyl]-3yl)hydrazinecarboxylate) including its
metabolites and degradates, in or on
Herb subgroup 19A, except chervil and
chive at 300 ppm, Timothy, forage at
200 ppm, Timothy, hay at 150 ppm,
Fruit, pome, group 11–10 at 0.7 ppm
and Vegetable, fruiting, group 8–10 at
4.0 ppm. In addition, this regulation
removes existing tolerances on ‘‘fruit,
pome, group 11’’ ‘‘vegetable, fruiting,
group 8’’ and existing time-limited
tolerances for ‘‘timothy, forage’’ and
‘‘timothy, hay’’ that are superseded by
this action.
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

Federal Register / Vol. 79, No. 151 / Wednesday, August 6, 2014 / Rules and Regulations
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 tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of 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

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

II. Summary of Petitioned-For Tolerance
In the Federal Register of Wednesday, July 6, 2011 (76 FR 39358)
(FRL-8875-6), 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 (PP1E7847) by the Interregional Research Project Number 4 (IR-
4), IR-4 Project Headquarters, 500 College Road East, Suite 201W,
Princeton, NJ 08540. The petition requested that 40 CFR 180.572 be
amended by establishing tolerances for residues of bifenazate:
Hydrazine carboxylic acid, 2-(4-methoxy-[1,1'-biphenyl]-3-yl)-
methylethyl ester in or on fruit, pome, group 11-10 at 0.75 parts per
million (ppm); herb, subgroup 19A dried leaves, except chervil, dried
and chive, dried, at 140 ppm; herb, subgroup 19A, fresh leaves at 30
ppm; timothy, forage at 140 ppm; timothy, hay at 120 ppm; and
vegetable, fruiting, group 8-10 at 2.0 ppm. That document referenced a
summary of the petition prepared by Chemtura Corporation, the
registrant, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the
notice of filing.
Based upon review of the data supporting the petition, EPA has
revised the proposed tolerance level and corrected the commodity
definition for certain commodities, and revised the tolerance
expression for bifenazate. The reasons for these changes are explained
in Unit IV.C.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.''
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified 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
[[Page 45695]]
aggregate exposure for bifenazate including exposure resulting from the
tolerances established by this action. EPA's assessment of exposures
and risks associated with bifenazate follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered their
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.
Bifenazate has low acute toxicity for the oral, dermal and
inhalation routes of exposure. For subchronic oral exposures, the dog
is the most sensitive species. For chronic oral exposures, the dog and
the rat are equally sensitive.
Subchronic and chronic studies in rats and dogs indicate that the
liver and hematopoietic system (spleen and bone marrow with associated
hematological findings) are the primary target organs in these species.
Additional toxicity was seen in the kidney (dogs following chronic
exposure) and adrenal cortex (male rats following subchronic exposure).
Decreases in body weight, body-weight gain, and food consumption were
also associated with liver and hematopoietic system toxicity in several
studies.
In the rat developmental toxicity study, the maternal effects
consisted of clinical signs of toxicity, decreased body weight and
body-weight gains, and reduced food consumption at the mid-dose.
Increases in early fetal resorptions occurred at the same doses that
caused maternal toxicity. In the rabbit developmental toxicity study,
there were no maternal or developmental effects up to the highest dose
tested (HDT). In the 2-generation rat reproduction study, the parental
effects occurred at the mid-dose and consisted of decreased body weight
and body-weight gains. There were no reproductive or offspring effects
up to the HDT.
In the acute neurotoxicity study, treatment related effects were
seen only at the HDT, and consisted of decreased motor activity
(rearing in females; center time in both sexes). In the subchronic
neurotoxicity study, effects were also only seen at the HDT (34.5
milligrams/kilogram/day (mg/kg/day) and consisted of decreased landing
foot splay (males), decreased fore- and hindlimb grip strength (males),
decreased motor activity measurements consisting of center times
(females) and rearing activity (both sexes). The level of concern (LOC)
for neurotoxicity in the bifenazate database is low however because;
The observed effects are well characterized;
They occur only at the highest doses tested; and
They are protected for by the studies used in the endpoint
selection.
There were no observed toxicological effects in the immunotoxicity
study up to the HDT.
In the mouse carcinogenicity study, males and females were tested
up to 225 ppm and 175 ppm, respectively, which elicited decreased body
weight and body-weight gains in females. In male mice, there was an
increase in the incidence of liver adenomas only, which was not
considered statistically significant by pair-wise comparison. There
also was no progression of the adenomas to carcinomas in males in this
study. A full battery of mutagenicity studies were negative for
mutagenic or clastogenic activity. Bifenazate is classified as ``not
likely'' to be carcinogenic to humans.
Specific information on the studies received and the nature of the
adverse effects caused by bifenazate 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, ``Bifenazate. Human-Health Risk
Assessment. Section 3 Registration Request to Add New Uses on Timothy
Forage and Hay; Herb, Subgroup 19A; and to Expand Existing Uses on Pome
Fruit, Group 11, and Fruiting Vegetables, Group 8'', dated May 15,
2014, page 40 in docket ID number EPA-HQ-OPP-2010-0904.
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 bifenazate used for
human risk assessment is shown in the Table of this unit.

Human Equivalent Dose (HED). HED's route-to-route extrapolation converts human and animal values from mg/L
concentrations to mg/kg oral-equivalent doses. The equation uses a single conversion factor to account for
default body weights and respiratory volumes. An activity factor is used to account for increased exposure
resulting from increased respiration. Using the HEC calculated (based upon terminal airway inflammation in
males), a conversion of the inhalation concentration to a dose (mg/L to mg/kg/day) was conducted as follows:
Human-Equivalent Dose (HED, mg/kg/day) = Dose (systemic HEC value, mg/L) x A x CF (L/hr/kg) x D (hours)
x AF = mg/kg
Where: A = absorption: Ratio of deposition and absorption in respiratory tract compared to absorption by the
oral route. CF = conversion Factor; a L/hr/kg factor which accounts for respiratory volume and body weight for
a given species and strain. D = duration; duration of daily animal or human exposure (hours). AF = activity
Factor; animal default is 1. The residential human equivalent dose for bifenazate is calculated as follows:
Residential HED: (0.0009 mg/L) x 1 x 6 x 8 x 1 = 0.135 mg/kg/day.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to bifenazate, EPA considered exposure under the petitioned-
for tolerances as well as all existing bifenazate tolerances in 40 CFR
180.572. EPA assessed dietary exposures from bifenazate in food as
follows:
i. Acute exposure. In conducting the acute dietary exposure
assessment EPA used the Dietary Exposure Evaluation Model--Food
Consumption Intake Database (DEEM-FCID, ver. 3.16), which incorporates
consumption information from the United States Department of
Agriculture's (USDA's) National Health and Nutrition Examination
Survey, What We Eat in America, (NHANES/WWEIA). This dietary survey was
conducted from 2003 to 2008.
As to residue levels in food, the acute analysis for the general
population, including infants and children, was unrefined and used
tolerance-level residues and 100 PCT. The acute analysis for females 13
to 49 years old was highly refined and incorporated data from the
USDA's Pesticide Data Program (PDP), crop field trial data, and PCT
estimates. DEEM (ver. 7.81) default processing factors were assumed for
all commodities excluding apple juice, grape juice, and wine/sherry.
The processing factors for these commodities were reduced to 1.0, based
on data from processing studies.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the DEEM-FCID, ver. 3-16 which incorporates
consumption information from the USDA NHANES/WWEIA; 2003-2008. As to
residue levels in food, the chronic dietary exposure analysis for all
population subgroups was partially refined and used tolerance-level
residues and PCT estimates. DEEM default processing factors were
assumed for all commodities excluding apple juice, grape juice, and
wine/sherry. The processing factors for these commodities were reduced
to 1.0 based on data from processing studies.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
classified bifenazate as ``not likely'' to be a human carcinogen.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk was not conducted.
iv. Anticipated residue and percent crop treated (PCT) information.
Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and
information on the anticipated residue levels of pesticide residues in
food and the actual levels of pesticide residues that have been
measured in food. If EPA relies on such information, EPA must require
pursuant to FFDCA section 408(f)(1) that data be provided 5 years after
the tolerance is established, modified, or left in effect,
demonstrating that the levels in food are not above the levels
anticipated. For the present action, EPA will issue such data call-ins
as are required by FFDCA section 408(b)(2)(E) and authorized under
FFDCA section 408(f)(1). Data will be required to be submitted no later
than 5 years from the date of issuance of these tolerances.
Section 408(b)(2)(F) of FFDCA states that the Agency may use data
on the actual percent of food treated for assessing chronic dietary
risk only if:
Condition a: The data used are reliable and provide a
valid basis to show what percentage of the food derived from such crop
is likely to contain the pesticide residue.
Condition b: The exposure estimate does not underestimate
exposure for any significant subpopulation group.
Condition c: Data are available on pesticide use and food
consumption in a particular area, the exposure estimate does not
understate exposure for the population in such area.
In addition, the Agency must provide for periodic evaluation of any
estimates used. To provide for the periodic evaluation of the estimate
of PCT as required by FFDCA section 408(b)(2)(F), EPA may require
registrants to submit data on PCT.
The Agency used PCT information as follows:
Maximum PCT estimates were used in the acute dietary risk
assessment: Almonds: 10%; apples: 5%; apricots: 10%; beans, green:
2.5%; caneberries: 30%; cantaloupes: 2.5%; cherries: 5%; cucumbers: 5%;
grapefruit: 5%; grapes: 20%; nectarines: 10%; oranges: 2.5%; peaches:
20%; pears: 30%; pecans: 2.5%; peppers: 10%; pistachios: 2.5%; plums/
prunes: 20%; potatoes: 5%; pumpkins: 5%; squash: 2.5%; strawberries:
65%; tomatoes: 10%; walnuts: 5%; and watermelon: 2.5%.
The following average PCT estimates were used in the chronic
dietary risk assessment: Almonds: 5%; apples: 5%; apricots: 5%; beans,
green: 1%; caneberries: 25%; cantaloupes: 1%; cherries: 2.5%;
cucumbers: 2.5%; grapefruit: 5%; grapes: 10%; nectarines: 5%; oranges:
1%; peaches: 10%; pears: 15%; pecans: 1%; peppers: 5%; pistachios:
2.5%; plums/prunes: 5%; potatoes: 5%; pumpkins: 2.5%; squash: 1%;
strawberries: 45%; tomatoes: 5%; walnuts: 2.5%; and watermelon: 1%.
In most cases, EPA uses available data from USDA/National
Agricultural Statistics Service (USDA/NASS), proprietary market
surveys, and the National Pesticide Use Database for the chemical/crop
combination for the most recent 6-7 years. EPA uses an average PCT for
chronic dietary risk analysis. The average PCT figure for each existing
use is derived by combining available public and private market survey
data for that use, averaging across all observations, and rounding to
the nearest 5%, except for those situations in which the average PCT is
less than one. In those cases, 1% is used as the average PCT and 2.5%
is used as the maximum PCT. EPA uses a maximum PCT for acute dietary
risk analysis. The maximum PCT figure is the highest observed maximum
value reported within the recent 6 years of available public and
private market survey data for the existing use and rounded up to the
nearest multiple of 5%.
The Agency believes that the three conditions discussed in Unit
III.C.1.iv. have been met. With respect to Condition a, PCT estimates
are derived from Federal and private market survey data, which are
reliable and have a valid basis. The Agency is reasonably certain that
the percentage of the food treated is not likely to be an
underestimation. As to Conditions b and c, regional consumption
information and consumption information for significant subpopulations
is taken into account through EPA's computer-based model for evaluating
the exposure of significant subpopulations including
[[Page 45698]]
several regional groups. Use of this consumption information in EPA's
risk assessment process ensures that EPA's exposure estimate does not
understate exposure for any significant subpopulation group and allows
the Agency to be reasonably certain that no regional population is
exposed to residue levels higher than those estimated by the Agency.
Other than the data available through national food consumption
surveys, EPA does not have available reliable information on the
regional consumption of food to which bifenazate may be applied in a
particular area.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for bifenazate in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of bifenazate. 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 First Index Reservoir Screening Tool (FIRST) model and
the dry bean application scenario (highest registered/proposed use
rate) and the Screening Concentrations in Ground Water (SCI-GROW)
model, the estimated drinking water concentrations (EDWCs) of
bifenazate acute exposures are estimated to be 37.3 ppb for surface
water and 0.014 ppb for ground water.
For chronic exposures for non-cancer assessments are estimated to
be 11.2 ppb for surface water and 0.014 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model.
For acute dietary risk assessment, the water concentration value of
37.3 ppb was used to assess the contribution to drinking water.
For chronic dietary risk assessment, the water concentration of
value 11.2 ppb was used to assess the contribution to drinking 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).
Bifenazate is currently registered for the following uses that
could result in residential exposures: Ornamental plants, including
bedding plants, flowering plants, foliage plants, bulb crops
perennials, trees, and shrubs. EPA assessed residential exposure using
the following assumptions: There is a potential for short-term dermal
and inhalation exposures by homeowners applying bifenazate.
Intermediate-term exposures are not likely because of the intermittent
nature of applications by homeowners.
The residential handler exposure assessment estimates dermal and
inhalation exposures for individuals using bifenazate on residential
ornamentals. The quantitative exposure/risk assessment developed for
residential handlers is based on the following scenarios:
i. Mixing/loading/applying liquids with manually-pressurized
handwand,
ii. Mixing/loading/applying liquids with hose-end sprayer,
iii. Mixing/loading/applying liquids with backpack, and
iv. Mixing/loading/applying liquids with sprinkler can.
Unit exposure values and estimates for area treated were taken from
the 2012 Residential SOPs: Gardens and Trees. An aggregate risk index
(ARI) was used since the LOCs for dermal exposure (100) and inhalation
exposure (30) are different. The target ARI is 1; therefore, ARIs of
less than 1 result in risk estimates of concern. The ARI was calculated
as follows.
Aggregate Risk Index (ARI) = 1 / [(Dermal LOC / Dermal
MOE) + (Inhalation LOC / Inhalation MOE)]
Short-term risk estimates for residential handlers are greatest for
exposure scenarios ``hose-end sprayer'' and ``backpack'' resulting in
ARIs of 80 and 66, respectively. Short-term dermal and inhalation risk
estimates to residential handlers do not exceed EPA's LOC for all
scenarios. All the ARIs are above 1 and do not exceed the Agency's LOC
for all scenarios.
Short-term dermal exposure and risk from residential post-
application have been assessed for bifenazate under the following
scenarios, routes of exposure and lifestages:
Gardens and Trees: adults (dermal) and children 6 to less
than or equal 11 years old (dermal).
These lifestages are not the only lifestages that could be
potentially exposed for these post-application scenarios; however, the
assessment of these lifestages is health protective for the exposures
and risks for any other potentially exposed lifestages. All adult and
children dermal post-application risk estimates for exposure to treated
trees and gardens are not of concern (MOEs >= 100). Details of
assumptions and factors the Agency applied in residential and
residential post-application exposure assessments are detailed in the
2012 Residential SOPs at https://www.epa.gov/pesticides/science/residential-exposure-sop.html.
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.''
EPA has not found bifenazate to share a common mechanism of
toxicity with any other substances, and bifenazate does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
bifenazate does not have 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 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 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. The prenatal and postnatal
toxicology database for bifenazate includes rat and rabbit
developmental toxicity studies and a 2-generation reproduction toxicity
study in rats. In the rat developmental toxicity study, the maternal
effects consisted of clinical signs of toxicity, decreased body weight
and body-weight gains, and reduced food consumption at the mid-dose.
Increases in early fetal resorptions occurred at the same doses that
caused maternal toxicity. In the
[[Page 45699]]
rabbit developmental toxicity study, there were no maternal or
developmental effects up to the HDT. In the 2-generation rat
reproduction study, the parental effects occurred at the mid-dose and
consisted of decreased body weight and body-weight gains. There were no
reproductive or offspring effects up to the HDT.
3. Conclusion. 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 bifenazate is complete.
ii. There is evidence of neurotoxicity in the bifenazate database.
The level of concern for neurotoxic effects in children is low however
because
The observed effects are well characterized;
They occur only at the highest doses tested; and
They are protected for by the studies used in the endpoint
selection.
iii. There is no evidence that bifenazate results in increased
susceptibility in in utero rats or rabbits in the pre- or postnatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The exposure databases are sufficient to determine the
nature and magnitude of the residue in food and water. For acute
exposure for the general population and chronic exposure, the dietary
exposure analyses are unlikely to underestimate exposure as they
incorporated tolerance-level residues, 100 PCT for acute exposure, PCT
for chronic exposure, and modeled drinking water estimates. For acute
analysis for females 13 to 49 years, the dietary analysis is unlikely
to underestimate exposure as PDP, crop field trial data, PCT estimates
and modeled drinking water estimates were utilized.
EPA made conservative (protective) assumptions in the ground water
and surface water modeling used to assess exposure to bifenazate in
drinking water. The dietary food and drinking water exposure
assessments will not underestimate the potential exposures for infants
and children. The residential use (ornamentals) is not expected to
result in post-application exposure to infants and children as well as
incidental oral exposure of toddlers. The post-application exposure
assessments are based upon the residential SOPs, which are based upon
reasonable worst-case assumptions and are not expected to underestimate
risk. These assessments will not underestimate the exposure and risks
posed by bifenazate.
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
aPAD and cPAD. For linear cancer risks, EPA calculates the lifetime
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. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to bifenazate will occupy <1.9% of the aPAD for children 1 to 2 years
old, the population group receiving the greatest exposure. The acute
dietary exposure estimates are not of concern to EPA (<100% aPAD) for
the general U.S. population and all population subgroups
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
bifenazate from food and water will utilize 74% of the cPAD for
children 1 to 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
bifenazate is not expected.
3. Short- and intermediate-term risks. Short- and intermediate-term
aggregate exposures take into account short- and intermediate-term
residential exposures plus chronic exposure to food and water
(considered to be a background exposure level). Bifenazate is currently
registered for uses that could result in short- and intermediate-term
residential exposures.
The short- and intermediate-term toxicological PODs for bifenazate
are the same for each route of exposure. Therefore, for residential
exposure scenarios, only short-term exposures were assessed, and are
considered to be protective of intermediate-term exposure and risk.
It was appropriate to aggregate postapplication dermal exposures
with dietary (food and water) exposures. The dermal postapplication
exposure to gardens and ornamentals scenario is the residential
exposure scenario with the greatest risk estimate for both adults and
children 6 <= 11 years old; therefore, the exposure estimates for this
scenario are protective of any other exposure scenarios.
For the adult and children 6 <= 11 years old short- and
intermediate-term aggregate risk assessment, the MOE approach was used
to estimate aggregate exposures as there are different PODs for oral
and dermal routes of exposure but the LOC are the same. The chronic
dietary exposure estimate for Adults 20-49 years old and Children 6-12
years old were used in the aggregate risk estimate for adults and
children 6 <= 11 years old, respectively.
All of the adult and children 6 <= 11 years old chronic dietary +
dermal aggregate risk estimates do not exceed EPA's LOC (MOEs >= 100).
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, bifenazate (classified as ``not likely'' to be a human
carcinogen) is therefore not expected to pose a cancer risk to humans.
5. 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 bifenazate residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies are available to enforce the
tolerance expression.
For plant commodities, high-performance liquid chromatography with
oxidative coulometric electrochemical detector (HPLC/ELCD) Method UCC-
D2341 is available as a primary enforcement method for the combined
residues of bifenazate and its metabolite D3598. The method has been
forwarded to the United States Food and Drug Administration (FDA) for
inclusion in the Pesticides Analytical Manual, Volume II (PAM II). The
limit of quantification (LOQ) and limit of detection (LOD) of Method
UCC-D2341 are 0.01 and 0.005 ppm, respectively. In addition, a liquid
chromatographic system with tandem mass spectrometers (LC-MS/MS) method
(NCL ME 245) was recently submitted as a confirmatory method and has
been forwarded to FDA.
For livestock commodities, HPLC methods with fluorescence detection
or ELCD are available as primary methods for the enforcement of
tolerances for residues of bifenazate and its regulated metabolites in
livestock matrices. The methods have undergone a successful validation
by the Agency and have been forwarded to FDA for inclusion in PAM
[[Page 45700]]
II. In addition, the LC-MS/MS Method NCL ME 259 was recently submitted
as a confirmatory method, and this method was also forwarded to FDA.
The validated LOQ was 0.01 ppm for each analyte. The LOD was reported
as 0.005 ppm.

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.
There are currently no established Codex MRLs for bifenazate in/on
herbs, and timothy forage and hay. Codex MRLs are established for pome
fruits (0.7 ppm), chili peppers (3 ppm), sweet peppers (2 ppm) and
tomato (0.5 ppm), but not for other members of Vegetable, fruiting,
group 8-10.
The U.S. is establishing a tolerance for Vegetable, fruiting, group
8-10 at 4.0 ppm for residues of bifenazate (and its metabolite). There
is an existing U.S. tolerance of 2 ppm for Vegetables, fruiting, crop,
group 8. This tolerance was established in 2003 prior to the
implementation of the Organization for Economic Co-Operation and
Development (OECD) calculation procedures. In 2007 Codex established
the MRLs for chili peppers, sweet peppers and tomato and relied on the
U.S. field trial data. Codex chose not to establish a group tolerance
for the fruiting vegetables but instead established separate Codex MRLs
for tomato, peppers and chili peppers using the highest observed
residue approach. The approach taken by Codex is not in line with how
the U.S. establishes crop group tolerances. Further, using the OECD
calculation procedures and based on data from bell and non-bell pepper
studies conducted in the U.S., and tomato studies conducted in Canada
and the U.S. results in the recommended tolerance of 4.0 ppm.
EPA is establishing the U.S. tolerance for residue in or on pome
fruit at 0.7 ppm, in harmonization with the established Codex MRL.
C. Revisions to Petitioned-For Tolerances
After reviewing supporting data and information, EPA modified
certain elements of the petition as proposed in the notice of filing,
as follows:
1. EPA corrected the proposed commodity definitions, ``Herb,
subgroup 19A, fresh leaves'' and ``Herb, subgroup 19A, dried leaves,
except chervil, dried and chive, dried'' to read ``Herb subgroup 19A,
except chervil and chive'' to specify crop coverage and for accuracy
and consistency in naming of commodities.
2. Using the OECD tolerance-calculation procedures, the Agency
modified proposed tolerance levels for certain commodities as follows:
i. A proposed tolerance at 140 ppm for ``Herb, subgroup 19A, dried
leaves, except chervil, dried and chive, dried'' was established for
``Herb, subgroup 19A, except chervil and chive'' at 300 ppm, and
ii. A proposed tolerance at 140 ppm on timothy, forage, was
established at 200 ppm (tolerance with regional registrations), and a
proposed tolerance of 120 ppm on timothy, hay, was established at 150
ppm (tolerance with regional registrations).
3. As petitioned-for, EPA is establishing tolerances with regional
registrations for timothy, forage and timothy, hay for regional use in
two counties, Eureka and Humboldt, in the State of Nevada. Applications
of bifenazate can only be made to timothy that is intended for use as
horse feed. Livestock feedstuffs are not derived from the proposed
crops of the subject petition, except for timothy. The Agency is
removing existing time-limited tolerances established for bifenazate
under section 18 emergency exemptions for timothy, forage and timothy,
hay at 50 ppm and 150 ppm, respectively, as they are superseded by this
action.
4. As previously stated, the U.S. tolerance for Vegetable,
fruiting, group 8-10 is being changed to 4.0 ppm. This is based the use
of the OECD calculation procedures on data from bell and non-bell
pepper studies conducted in the United States, and tomato studies
conducted in Canada and the United States.
In addition, the Agency is revising the tolerance expressions for
bifenazate tolerances in order to conform to current EPA policy as
follows:
5. 40 CFR Sec. 180.572(a)(1) is revised to read as follows:
Tolerances are established for residues of bifenazate (1-methylethyl 2-
(4-methoxy[1,1'-biphenyl]-3-yl)hydrazinecarboxylate) including its
metabolites and degradates, in or on the commodities listed in the
following table. Compliance with the tolerance levels specified are to
be determined by measuring only the sum of bifenazate and its
metabolite, diazinecarboxylic acid, 2-(4-methoxy-[1,1'-biphenyl]-3-yl),
1-methylethyl ester, (calculated as the stoichiometric equivalent of
bifenazate) in or on food commodities, and
6. The tolerance expression for 40 CFR Sec. 180.572(a)(2) is
modified as follows: Tolerances are established for residues of
bifenazate (1-methylethyl 2-(4-methoxy[1,1'-biphenyl]-3-yl)
hydrazinecarboxylate) including its metabolites and degradates, in or
on the commodities listed in the following table. Compliance with the
tolerance levels specified are to be determined by measuring only the
sum of bifenazate and its metabolites diazinecarboxylic acid, 2-(4-
methoxy-[1,1'-biphenyl]-3-yl), 1-methylethyl ester; 1,1'-biphenyl, 4-
ol; and 1,1'-biphenyl, 4-oxysulfonic acid (calculated as the
stoichiometric equivalent of bifenazate) in or on food commodities.
V. Conclusion
Therefore, tolerances are established for residues of bifenazate
(1-methylethyl 2-(4-methoxy[1,1'-biphenyl]-3-yl)hydrazinecarboxylate)
including its metabolites and degradates, in or on Herb subgroup 19A,
except chervil and chive at 300 ppm, Timothy, forage at 200 ppm,
Timothy, hay at 150 ppm, Fruit, pome, group 11-10 at 0.7 ppm and
Vegetable, fruiting, group 8-10 at 4.0 ppm. In addition, this
regulation removes existing tolerances on ``fruit, pome, group 11''
``vegetable, fruiting, group 8'' and existing time-limited tolerances
for ``timothy, forage'' and ``timothy, hay'' that are superseded by
this action.
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
[[Page 45701]]
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 tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of 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).
