II. Background and Statutory Findings
In the Federal Register of January 28, 2004 (69 FR 4143) (FRL-7339-
6), EPA issued a notice pursuant to section 408(d)(3) of FFDCA,
21
U.S.C. 346a(d)(3), announcing the filing of a pesticide
petitions (PP
1F6290, 2F6445, and 2F6479) by Bayer CropScience, 2 T.W.
Alexander
Drive, Research Triangle Park, NC 27709; and (PP 1E6318, 3E6776,
and
3E6583) by the Interregional Research Project Number 4 (IR-4),
Technology Centre and Rutgers State University of New Jersey, 681
U.S.
Highway #1 South, North Brunswick, NJ 08902-390. The petitions
requested that 40 CFR 180.436 be amended by establishing tolerances
for
residues of the insecticide cyfluthrin, cyano (4-fluoro-3-
phenoxyphenyl)methyl-3-(2,2-dichloroethenyl)-2,2-dimethyl-
cyclopropanecarboxylate, in or on almond hulls at 1.0 parts per
million
(ppm); pistachio at 0.01 ppm; and tree nuts, crop group 14 at 0.01
ppm
(PP 1F6290); cucurbit vegetable crop
group at 0.10 ppm; fruiting
vegetable group at 0.5 ppm; leafy Brassica greens subgroup at 7.0
ppm;
leafy vegetable group at 6.0 ppm; pome fruit group at 0.10 ppm;
pome
fruit wet pomace at 0.30 ppm; stone fruit group at 0.30 ppm; wheat
forage, wheat hay and wheat straw at 5.0 ppm; and wheat shorts at
3.5
ppm (PP 2F6445); grape at 0.8 ppm;
grape, raisin at 3.5 ppm; peanut at
0.01 ppm; and peanut, hay at 6.0 ppm (PP 2F6479);
tuberous and corm
vegetable subgroup at 0.01 ppm (PP 1E6318);
turnip greens at 7 ppm (PP
3E6583); and grass forage at 6 ppm; grass hay at 8 ppm; and
pea and
bean, dried shelled, except soybean, subgroup 6C at 0.15 ppm (PP
3E6776). That notice included a summary of the petition prepared
by
Bayer Crop Science, the registrant.
The registrant has submitted a
request to voluntarily
[[Page 53945]]
cancel uses of cyfluthrin on stored grains
effective December 31, 2004.
Based on EPA's review, the petitions were
revised by the
petitioners as follows: i. by increasing
proposed tolerances for grapes
to 1.0 ppm and the proposed tolerances for wheat hay and straw to
6.0
ppm; ii. by increasing the proposed pome fruit crop group tolerance
to
0.5 ppm to harmonize with the Codex apple MRL and deleting the proposed
tolerance on pome fruit wet pomace since expected residues are below
the pome fruit tolerance of 0.5 ppm; iii. by decreasing proposed
tolerances for almond hulls to 0.5 ppm; iv. by removing tolerances
for
peanut oil since residues will be lower than residues in peanuts;
v. by
removing tolerances in prume since maximum expected residues are
below
the proposed tolerance for the stone fruit crop group; and vi. by
withdrawing the proposed tolerance for wheat shorts since it is
already
covered under wheat milled by products.
Although EPA requested a number of changes
to the initial
petitions, the nature of the changes (changes in tolerance levels)
are
not considered significant. Therefore, EPA is issuing this as a
final
action. EPA is also removing the existing
tolerance for potato, since a
tolerance is being established on the entire tuberous and corm
vegetable subgroup; removing time-limited tolerances established
for
grape and grape, raisin at 1.0 and 1.5 ppm, respectively, in connection
with Section 18 emergency exemptions since they are no longer needed;
and establishing tolerances with regional registrations for grass
forage and hay.
One comment was received in response to the notice of filing. The
comment is described and discussed in Unit V. Comments.
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or
on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there
is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and
in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that
there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue.
. .
.''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion
of the
regulatory requirements of section 408 of FFDCA and a complete
description of the risk assessment process, see the final rule on
Bifenthrin Pesticide Tolerances in the Federal Register November
26,
1997 (62 FR 62961) (FRL-5754-7).
III. Aggregate Risk Assessment and Determination of Safety
Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed
the
available scientific data and other relevant information in support
of
this action. EPA has sufficient data to assess the hazards of and
to
make a determination on aggregate exposure, consistent with section
408(b)(2) of FFDCA, for the cyfluthrin tolerances described in Unit
II.
EPA's assessment of exposures and risks associated with establishing
the tolerances 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. The nature of the toxic effects caused by cyfluthrin and
its
enriched isomer, beta-cyfluthrin]
as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies reviewed
are discussed in the Federal
Register of September 27, 2002 (67 FR 60976) (FRL-7199-8).
Cyfluthrin is a type II pyrethroid
(i.e., it has a cyano group at
the carbon position of the alcohol moiety and it is more effective
when
the ambient temperature is raised). Beta-cyfluthrin
is an enriched
isomer of cyfluthrin. Bridging data on beta-cyfluthrin were submitted
so that the toxicity of beta-cyfluthrin could be compared with that
of
cyfluthrin and the databases could be combined to form one complete
database for both chemicals. The scientific quality of the data
is
relatively high, and the toxicity profiles of both cyfluthrin and
beta-
cyfluthrin can be characterized for all effects, including potential
developmental, reproductive and neurotoxic effects. A beta-cyfluthrin
developmental neurotoxicity study has been submitted and a preliminary
review indicates that effects are seen only at doses higher than
those
chosen for risk assessment purposes.
B. Toxicological Endpoints
The dose at which no adverse effects are observed (the NOAEL) from
the toxicology study identified as appropriate for use in risk
assessment is used to estimate the toxicological level of concern
(LOC). However, the lowest dose at which adverse effects of concern
are
identified (the LOAEL) is sometimes used for risk assessment if
no
NOAEL was achieved in the toxicology study selected. An uncertainty
factor (UF) is applied to reflect uncertainties inherent in the
extrapolation from laboratory animal data to humans and in the
variations in sensitivity among members of the human population
as well
as other unknowns. An UF of 100 is routinely used, 10X to account
for
interspecies differences and 10X for intraspecies differences.
Three other types of safety or uncertainty factors may be used:
``Traditional UFs'' the ``special FQPA safety factor;'' and the
``default FQPA safety factor.'' By the term ``traditional UF,''
EPA is
referring to those additional UFs used prior to FQPA passage to
account
for database deficiencies. These traditional UFs have been incorporated
by the FQPA into the additional safety factor for the protection
of
infants and children. The term ``special FQPA safety factor'' refers
to
those safety factors that are deemed necessary for the protection
of
infants and children primarily as a result of the FQPA. The ``default
FQPA safety factor'' is the additional 10X safety factor that is
mandated by the statute unless it is decided that there are reliable
data to choose a different additional factor (potentially a traditional
UF or a special FQPA safety factor).
For dietary risk assessment (other than cancer) the Agency uses
the
UF to calculate an acute or chronic reference dose (aRfD or cRfD)
where
the RfD is equal to the NOAEL divided by an UF of 100 to account
for
interspecies and intraspecies differences and any traditional UFs
deemed appropriate (RfD = NOAEL/UF). Where a special FQPA safety
factor
or the default FQPA safety factor is used, this additional factor
is
applied to the RfD by dividing the RfD by such additional factor.
The
acute or chronic Population Adjusted Dose (aPAD or cPAD) is a
modification of the RfD to accommodate this type of safety factor.
For non-dietary risk assessments (other than cancer) the UF is used
to determine the LOC. For example, when 100 is the appropriate UF
(10X
to account for interspecies differences and
[[Page 53946]]
10X for intraspecies differences) the LOC is 100. To estimate risk,
a
ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/
exposure) is calculated and compared to the LOC.
The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify carcinogenic risk. The
Q*
approach assumes that any amount of exposure will lead to some degree
of cancer risk. A Q* is calculated and used to estimate risk which
represents a probability of occurrence of additional cancer cases
(e.g., risk). An example of how such a probability risk is expressed
would be to describe the risk as one in one hundred thousand (1
x
10-5), one in a million (1 x 10- 6), or one in
ten million (1 x 10-7). Under certain specific
circumstances, MOE calculations will be used for the carcinogenic
risk
assessment. In this non-linear approach, a ``point of departure''
is
identified below which carcinogenic effects are not expected. The
point
of departure is typically a NOAEL based on an endpoint related to
cancer effects though it may be a different value derived from the
dose
response curve. To estimate risk, a ratio of the point of departure
to
exposure (MOEcancer = point of departure/exposures) is
calculated.
A summary of the toxicological endpoints for cyfluthrin used for
human risk assessment is shown in following Table 1:

C. Exposure Assessment
The residue included in the risk assessment and tolerance
expression for plants and animals is cyfluthrin per se. Parent
cyfluthrin is also the residue of concern in the drinking water
assessment.
1. Dietary exposure from food and feed uses. Tolerances have been
established (40 CFR 180.436) for the residues of cyfluthrin, in
or on a
variety of raw agricultural commodities. Tolerances have been
established on plant commodities ranging from 0.01 ppm for corn
grain
and potatoes to 300 ppm for aspirated grain fractions and on animal
commodities ranging from 0.01 ppm for poultry commodities to 15
ppm for
milk fat. In addition, a tolerance of 0.05
ppm is established for
cyfluthrin in animal feeds and processed foods as a
[[Page 53947]]
result of its use in food, and feed-handling
establishments.
Although the uses on stored grain have been
voluntarily cancelled
by the registrant established tolerances reflecting these uses are
to
remain in 40 CFR Sec. 180.436(a)(1) to allow for clearance of the
remaining product and treated stored grain from the channels of
trade.
Although the Agency did not specifically include potential cyfluthrin
residues in stored grains in the dietary exposure assessments, the
Agency concludes that these assessments do not underestimate dietary
exposure and risk because:
• About 90% of the stored grain usage was for treatment of
stored wheat grain, so potential exposure from cyfluthrin use on
stored
grains would come from wheat;
• Residue monitoring data in wheat flour indicate very low
or non-detectable residues from cyfluthrin use on stored grain;
• The current dietary exposure estimates from the remaining
existing and the newly proposed uses includes a new foliar use on
wheat. The wheat field trial data used to estimate dietary exposure
reflect maximum rates and minimum pre-harvest intervals (PHI's),
and
these residues were significantly higher than monitoring data residues
for wheat. Monitoring data residues in wheat flour from cyfluthrin
use
on stored grain were so low that they would not increase dietary
exposure estimates if they had been included in the assessment;
• Exposure from residues in wheat (based on the high end
foliar use residues) was not significant for any of the population
subgroups, including infants and children; and
• Residues in stored grains were not a major component of
secondary residue estimates in livestock commodities, and concomitant
dietary exposure from consumption of animal commodities such as
meat
and milk.
Risk assessments were conducted by EPA to assess dietary exposures
from cyfluthrin in food as follows:
i. Acute exposure. Acute dietary 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.
In conducting the acute dietary risk assessment EPA used the
Dietary Exposure Evaluation Model software with the Food Commodity
Intake Database (DEEMTM/FCID), which incorporates food
consumption data as reported by respondents in the United States
Department of Agriculture (USDA) 1994-1996, and 1998 Nationwide
Continuing Surveys of Food Intake by Individuals (CSFII), and
accumulated exposure to the chemical for each commodity. The following
assumptions were made for the acute exposure assessments: Percent
crop
treated (PCT) values for crops with established tolerances, for
crops
with proposed tolerances, anticipated residues in animal commodities,
and processing factors (including washing and peeling factors).
Crop
field trial data were used for proposed commodities and Pesticide
Data
Program (PDP) monitoring data were used for registered commodities.
ii. Chronic exposure. In conducting the chronic dietary risk
assessment EPA used the DEEMTM software with the FCID, which
incorporates food consumption data as reported by respondents in
the
USDA 1994-1996, and 1998 Nationwide CSFII, and accumulated exposure
to
the chemical for each commodity. The following assumptions were
made
for the chronic exposure assessments: Average PCT values for crops
with
established tolerances, projected PCT estimates for crops with proposed
tolerances, anticipated residues in animal commodities, and processing
factors (including washing and peeling factors). Crop field trial
data
were used for proposed commodities, and PDP monitoring data were
used
for registered commodities.
iii. Anticipated residue and PCT information.
Section 408(b)(2)(E)
of the 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 chemicals that have been measured in
food.
If EPA relies on such information, EPA must pursuant to section
408(f)(1) require 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. Following the initial
data submission, EPA is authorized to require similar data on a
time
frame it deems appropriate. For the present action, EPA will
issue such
Data Call-Ins for information relating to anticipated residues as
are
required by FFDCA section 408(b)(2)(E) and authorized under FFDCA
section 408(f)(1). Such Data Call-Ins will be required to be submitted
no later than 5-years from the date of issuance of this tolerance.
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 the Agency can make the following findings: Condition
1,
that 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
such
pesticide residue; condition 2, that the exposure estimate does
not
underestimate exposure for any significant subpopulation group;
and
condition 3, if 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 section 408(b)(2)(F) of FFDCA, EPA may require registrants to
submit
data on PCT.
The Agency used PCT information as follows. Average and maximum
values for PCT data were used in the chronic and acute analyses,
respectively, for the following commodities with established
tolerances: Alfalfa (1 chronic, 2.5 acute), broccoli (3 chronic,
5
acute) cabbage (8 chronic, 12 acute), cantaloupes (2 chronic, 5
acute),
carrots (1 chronic, 5 acute), cauliflower (1 chronic, 2.5 acute),
corn
(5 chronic, 10 acute), cotton (10 chronic, 15 acute), garlic (1
chronic, 2.5 acute), grapefruit (1 chronic, 2.5 acute), green beans
(1
chronic, 2.5 acute), lemons (5 chronic, 10 acute), lettuce (5 chronic,
10 acute), mustard greens (1 chronic, 2.5 acute), onions (1 chronic,
2.5 acute), oranges (15 chronic, 20 acute), peas (1 chronic, 2.5
acute), peppers (10 chronic, 15 acute), potatoes (25 chronic, 35
acute), pumpkins (1 chronic, 5 acute), sorghum (1 chronic, 2.5 acute),
soybeans (1 chronic, 2.5 acute), squash (1 chronic, 2.5 acute),
sugarcane (5 chronic, 8 acute), sunflowers (3 chronic, 5 acute),
sweet
corn (5 chronic, 8 acute), tangerines (5 chronic, 8 acute), tomatoes
(5
chronic, 8 acute), and watermelons (5 chronic, 8 acute).
Projected PCT estimates were used for commodities with proposed
tolerances as follows: Apples 73%, grapes 23%, peaches 39%, pears
59%,
plums 28%, spinach 15%, winter wheat 4%, and collards greens 15%.
The Agency believes that the three conditions listed in Unit
III.C.1.iii have been met. With respect to Condition 1, PCT estimates
are derived from available federal, state, and private market survey
data. For existing crop sites on pesticide registrations (``existing
use''), EPA uses an average PCT for chronic dietary exposure estimates.
The average PCT figure is derived by combining available federal,
state, and private market survey data on the existing use, averaging
by
year, averaging across all years, and rounding
[[Page 53948]]
up to the nearest multiple of five except for those situations
in which
the average PCT is less than one. In those cases < 1% is used
as the
average and < 2.5% is used as the maximum. EPA uses a maximum
PCT for
acute dietary exposure estimates. The maximum PCT figure is the
single
maximum value reported overall from available federal, state, and
private market survey data on the existing use, across all years,
and
rounded up to the nearest multiple of five. However, in cases where
the
rounded average PCT and the maximum PCT were initially identical
at 5%,
the maximum was further adjusted upward to 8%. In
most cases, EPA uses
available data from United States Department of Agriculture /National
Agricultural Statistics Service (USDA/NASS), Proprietary Market
Surveys, and the National Center for Food and Agriculture Policy
(NCFAP) for the most recent 6 years. The Agency is reasonably certain
that the percentage of the food treated is not likely to be an
underestimation
The Agency projects PCT for a new pesticide use by assuming that
the PCT for the pesticide's initial five years will not exceed the
average PCT of the dominant pesticide (the one with the largest
PCT)
within its chemical type over three latest available years. For
apples,
grapes, peaches, pears, plums, and winter wheat the chemical type
within which cyfluthrin was compared consisted of all other
insecticides. For spinach and collards the corresponding chemical
type
consisted of all other synthetic pyrethroids with which cyfluthrin
was
price competitive (which excluded permethrin for spinach). The PCTs
included in the average may be each for the same pesticide or for
different pesticides since the same or different pesticides may
dominate for each year selected. Typically, EPA uses USDA/NASS as
the
source for raw PCT data because it is non-proprietary and directly
available without computation. The assumption was made that cyfluthrin
would entirely replace the current market leader among all insecticides
for each crop. This assumption is a conservative one because it
is not
likely that cyfluthrin will entirely replace the market leader for
each
commodity. For spinach and collard greens, the Agency looked at
all the
competing pyrethroids only (as opposed to all insecticides) and
assumed
that cyfluthrin would compete with pyrethroids that are priced
competitively with cyfluthrin. The assumption was made that cyfluthrin
would entirely replace the current market leader among all competitive
pyrethroids for spinach and collards. The value of 15% used for
spinach
and collard greens is very consistent with the PCT values determined
for the registered commodities. These are considered to be conservative
estimates of the percent crop treated that cyfluthrin will obtain.
This method of projecting PCT for a new pesticide, with or without
regard to specific pest(s), produces an upper-end projection that
is
unlikely, in most cases, to be exceeded in actuality because the
dominant pesticide is well-established and accepted by farmers.
Factors
that bear on whether a projection based on the dominant pesticide
could
be exceeded are whether the new pesticide is more efficacious or
controls a broader spectrum of pests than the dominant pesticide
within
its similar type, whether it is more cost-effective than the dominant
pesticide, and whether it is likely to be readily accepted by growers
and experts. These factors have been considered for cyfluthrin,
and
they indicate that it is unlikely that actual PCT for cyfluthrin
will
exceed the PCT for the dominant pesticide in the next five years.
As to Conditions 2 and 3, 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 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
information on the regional consumption of food to which cyfluthrin
may
be applied in a particular area.
2. Dietary exposure from drinking water.
The Agency lacks
sufficient monitoring exposure data to complete a comprehensive
dietary
exposure analysis and risk assessment for cyfluthrin in drinking
water.
Because the Agency does not have comprehensive monitoring data,
drinking water concentration estimates are made by reliance on
simulation or modeling taking into account data on the physical
characteristics of cyfluthrin.
The Agency uses the FQPA Index Reservoir Screening Tool (FIRST)
or
the Pesticide Root Zone Model/Exposure Analysis Modeling System
(PRZM/
EXAMS), to produce estimates of pesticide concentrations in an index
reservoir. The SCI-GROW model is used to predict pesticide
concentrations in shallow ground water. For a screening-level
assessment for surface water EPA will use FIRST (a Tier 1 model)
before
using PRZM/EXAMS (a Tier 2 model). The FIRST model is a subset of
the
PRZM/EXAMS model that uses a specific high-end runoff scenario for
pesticides. Both FIRST and PRZM/EXAMS incorporate an index reservoir
environment, and both models include a percent crop (PC) area factor
as
an adjustment to account for the maximum PC coverage within a watershed
or drainage basin.
None of these models include consideration of the impact processing
(mixing, dilution, or treatment) of raw water for distribution as
drinking water would likely have on the removal of pesticides from
the
source water. The primary use of these models by the Agency at this
stage is to provide a screen for sorting out pesticides for which
it is
unlikely that drinking water concentrations would exceed human health
levels of concern.
Since the models used are considered to be screening tools in the
risk assessment process, the Agency does not use estimated
environmental concentrations (EECs), which are the model estimates
of a
pesticide's concentration in water. EECs derived from these models
are
used to quantify drinking water exposure and risk as a %RfD or %PAD.
Instead drinking water levels of comparison (DWLOCs) are calculated
and
used as a point of comparison against the model estimates of a
pesticide's concentration in water. DWLOCs are theoretical upper
limits
on a pesticide's concentration in drinking water in light of total
aggregate exposure to a pesticide in food, and from residential
uses.
Since DWLOCs address total aggregate exposure to cyfluthrin they
are
further discussed in the aggregate risk sections in Unit III.E.
Based on the FIRST and SCI-GROW models, the EECs of cyfluthrin for
acute exposures are estimated to be 3.4 ppb for surface water and
0.0016 ppb for ground water. The EECs for chronic exposures are
estimated to be 0.082 ppb for surface water and 0.0016 ppb for ground
water.
3. From non-dietary exposure. The term ``residential exposure''
is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
[[Page 53949]]
Cyfluthrin is currently registered for use on a variety of indoor
(e.g. total release fogger and crack and crevice spray) and outdoor
(e.g. spray fogger) applications. Residential exposure for adults
was
assessed via the inhalation and dermal routes, while exposure for
infants and children was assessed via inhalation, dermal, and oral
(hand-to-mouth) routes. Outdoor handler inhalation and dermal exposure
were assessed. Residential applicator for indoor total release fogger
was not assessed quantitatively, because indoor inhalation exposure
to
a homeowner would likely be less than inhalation exposure to a
homeowner that would result from outdoor lawn treatments.
Residential post-application inhalation exposure
following
treatments to lawns was estimated using time weight averages from
an
imidacloprid study (Eberhart and Ellisor, 1994). In the study, air
concentration measurements were taken in the vicinity of the volunteer
subjects performing the Jazzercize routines. These data served as
appropriate surrogate data for cyfluthrin since the vapor pressure
of
cyfluthrin (3.3 x 10-8 torr) is similar to that of
imidacloprid (6.9 x 10-9 torr).
Residential MOEs were assessed for indoor and outdoor uses for
application and post-application exposure. This is considered a
conservative assessment assuming the lawn and carpet uses happen
on the
same day. All residential cyfluthrin MOEs calculated were well above
the target MOEs (100 for inhalation, oral, and dermal exposures)
and
therefore, do not exceed the Agency's level of concern.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance,
the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Cyfluthrin is a member of the pyrethroid class of pesticides. EPA
is not currently following a cumulative risk approach based on a
common
mechanism of toxicity for the pyrethroids. Although all pyrethroids
alter nerve function by modifying the normal biochemistry and
physiology of nerve membrane sodium channels, available data show
that
there are multiple types of sodium channels and it is currently
unknown
whether the pyrethroids as a class have similar effects on all channels
or whether modifications of different types of sodium channels would
have a cumulative effect. Nor do we have a clear understanding of
effects on key downstream neuronal function, e.g., nerve excitability,
or how these key events interact to produce their compound specific
patterns of neurotoxicity. Without such understanding, there is
no
basis to make a common mechanism of toxicity finding. There is ongoing
research by the EPA's Office of Research and Development and pyrethroid
registrants to evaluate the differential biochemical and physiological
actions of pyrethroids in mammals. This research is expected to
be
completed by 2007. When available, the Agency will consider this
research and make a determination of common mechanism as a basis
for
assessing cumulative risk. For information regarding EPA's
procedures
for cumulating effects from substances found to have a common mechanism
on EPA's website at
http://www.epa.gov/pesticides/cumulative/.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional tenfold margin of safety for infants and children
in the
case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the data base on toxicity and exposure
unless EPA determines based on reliable data that a different margin
of
safety will be safe for infants and children. Margins of safety
are
incorporated into EPA risk assessments either directly through use
of a
margin of exposure (MOE) analysis or through using uncertainty (safety)
factors in calculating a dose level that poses no appreciable risk
to
humans. In applying this provision, EPA either retains the default
value of 10X when reliable data do not support the choice of a
different factor, or, if reliable data are available, EPA uses a
different additional safety factor value based on the use of
traditional uncertainty factors and/or FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There was no evidence of
increased susceptibility of rats or rabbits to in utero exposure
in
developmental oral studies; however, there
was some indication of
increased susceptibility in developmental inhalation studies. A
clear
NOAEL was established for the fetal effects in every case. No residual
uncertainties were identified.
The data also demonstrated increased susceptibility
of rats and
mice to postnatal exposure to cyfluthrin. A clear NOAEL was established
for the offspring effects in every case. No residual uncertainties
were
identified.
3. Conclusion. EPA determined that the FQPA SF to protect
infants
and children should be removed. The recommendation is based on the
following:
• The toxicology databases for cyfluthrin and beta-
cyfluthrin together are considered adequate for selecting toxicity
endpoints for risk assessment. The toxicity profiles of both cyfluthrin
and beta-cyfluthrin can be characterized for all effects, including
potential developmental, reproductive and neurotoxic effects. Exposure
data are complete or are estimated based on data that reasonably
accounts for potential exposures.
• There is no evidence of increased susceptibility of rats
or rabbits to in utero exposure in developmental oral studies, and
the
degree of concern for the effects observed
in the inhalation
developmental studies is considered low since a clear NOAEL was
established for the fetal effects in every case.
• The NOAEL used for short-term inhalation exposure
scenarios is protective of the effects seen in the developmental
studies via the inhalation route.
• The degree of concern for the effects
observed in the
reproductive studies was considered low since a clear NOAEL was
established for the offspring effects in every case.
• The NOAEL used to establish the cRfD for all populations
is protective of the effects seen in the young in the reproduction
studies.
• A beta-cyfluthrin developmental neurotoxicity study
has
been submitted and a preliminary review indicates that effects are
seen
only at doses higher than those chosen for risk assessment purposes.
E. Aggregate Risks and Determination of Safety
To estimate total aggregate exposure to a pesticide from food,
drinking water, and residential uses, the Agency calculates DWLOCs
which are used as a point of comparison against EECs. DWLOC values
are
not regulatory standards for drinking water. DWLOCs are theoretical
upper limits on a pesticide's concentration in drinking water in
light
of total aggregate exposure to a pesticide in food and residential
uses. In calculating a DWLOC, the Agency determines how much of
the
acceptable exposure (i.e., the PAD) is available for exposure through
drinking water e.g., allowable chronic water exposure (mg/kg/day)
=
cPAD - (average
[[Page 53950]]
food + residential exposure). This allowable exposure through drinking
water is used to calculate a DWLOC.
A DWLOC will vary depending on the toxic endpoint, drinking water
consumption, and body weights. Default body weights and consumption
values as used by the EPA's Office of Water are used to calculate
DWLOCs: 2 liter (L)/70 kg (adult male), 2L/60 kg (adult female),
and
1L/10 kg (child). Default body weights and drinking water consumption
values vary on an individual basis. This variation will be taken
into
account in more refined screening-level and quantitative drinking
water
exposure assessments. Different populations will have different
DWLOCs.
Generally, a DWLOC is calculated for each type of risk assessment
used:
Acute, short-term, intermediate-term, chronic, and cancer.
When EECs for surface water and ground water are less than the
calculated DWLOCs, EPA concludes with reasonable certainty that
exposures to the pesticide in drinking water (when considered along
with other sources of exposure for which EPA has reliable data)
would
not result in unacceptable levels of aggregate human health risk
at
this time. Because EPA considers the aggregate risk resulting from
multiple exposure pathways associated with a pesticide's uses, levels
of comparison in drinking water may vary as those uses change. If
new
uses are added in the future, EPA will reassess the potential impacts
of residues of the pesticide in drinking water as a part of the
aggregate risk assessment process.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food to
cyfluthrin will occupy 42% of the aPAD for the U.S. population,
34% of
the aPAD for females 13-years and older, 85% of the aPAD for all
infants < 1 year old, and 81% of the aPAD for children 3-5 years
old,
the children population at greatest exposure. In addition, there
is
potential for acute dietary exposure to cyfluthrin in drinking water.
After calculating DWLOCs and comparing them to the EECs for surface
water and ground water, EPA does not expect the aggregate exposure
to
exceed 100% of the aPAD, as shown in the following Table 2:

2. Chronic risk. Using the exposure assumptions described
in this
unit for chronic exposure, EPA has concluded that exposure to
cyfluthrin from food will utilize 1.5% of the cPAD for the U.S.
population, 2.4% of the cPAD for all infants < 1 year old, the
infant
subpopulations at greatest exposure, and 5.7% of the cPAD for children
1-2 years old, the children subpopulation at greatest exposure.
The
registered residential termiticide uses do constitute a chronic
inhalation exposure scenario, however, the vapor pressure of cyfluthrin
is so low (3.3 x 10-8 torr) that such exposures are
anticipated to be negligible. In addition, there is potential for
chronic dietary exposure to cyfluthrin in drinking water. After
calculating DWLOCs and comparing them to the EECs for surface water
and
ground water, EPA does not expect the aggregate exposure to exceed
100%
of the cPAD, as shown in the following Table 3:

3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level).
Cyfluthrin is currently registered for use that could result in
short-term residential exposure and the Agency has determined that
it
is appropriate to aggregate chronic food and water and short-term
exposures for cyfluthrin.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded that food and residential exposures
aggregated result in aggregate MOEs =/>500. These aggregate MOEs
do not
exceed the Agency's level of concern for aggregate exposure to food
and
residential uses. In addition, short-term DWLOCs were calculated
and
compared to the EECs for chronic exposure of cyfluthrin in ground
water
and surface water. After calculating DWLOCs and comparing them to-the
EECs for surface water and ground water, EPA does not expect short-term
aggregate exposure to exceed the Agency's level of concern, as shown
in
the following Table 4:

4. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account residential exposure plus chronic exposure to
food
and water (considered to be a background exposure level).
Using the exposure assumptions described in this unit for
intermediate-term exposures, EPA has concluded that food and
residential exposures aggregated result in aggregate MOEs =/>
250.
These aggregate MOEs do not exceed the Agency's level of concern
for
aggregate exposure to food and residential uses. In addition,
intermediate-term DWLOCs were calculated and compared to the EECs
for
chronic exposure of cyfluthrin in ground and surface water. After
calculating DWLOCs and comparing them to the EECs for surface water
and
ground water, EPA does not expect intermediate-term aggregate exposure
to exceed the Agency's level of concern, as shown in following Table
5:

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, and to infants and children from aggregate
exposure to cyfluthrin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (GC/electron capture detection
(ECD) methods) is available in PAM Vol. II to enforce the tolerances.
GC/ECD enforcement method 85823, and Bayer's GC/MS method 108139-1,
with modifications, were used to analyze samples in the current
crop
field trials and processing studies. Each method was adequately
validated using fortified control samples analyzed in conjunction
with
the field trial or processing study samples.
B. International Residue Limits
A tolerance of 0.5 ppm is recommended for the pome fruit crop group
to harmonize with the Codex apple MRL.
V. Comments
In response to the notice of filing one communication was received
from a private citizen objecting to the establishment of the proposed
tolerances. The comment contained general and unsubstantiated
objections to the use of pesticides on food , the use of animal
testing
to determine the safety of pesticides, and EPA's risk assessment
and
safety finding methodologies. The Agency understands the commentor's
concerns and recognizes that some individuals believe that pesticides
should be banned completely. However, under the existing legal
framework provided by section 408 of the Federal Food, Drug and
Cosmetic Act (FFDCA) EPA is authorized to establish pesticide
tolerances or exemptions where persons seeking such tolerances or
exemptions have demonstrated that the pesticide meets the safety
standard imposed by that statute.
The Agency disagrees with the commenter's objections to animal
testing. Since humans and animals have complex organ systems and
mechanisms for the distribution of chemicals in the body, as well
as
processes for eliminating toxic substances from their systems, EPA
relies on laboratory animals such as rats and mice to mimic the
complexity of human and higher-order animal physiological responses
when exposed to a pesticide. EPA is committed, however, to reducing
the
use of animals whenever possible. EPA-required studies include animals
only when the requirements of sound toxicological science make the
use
of an animal absolutely necessary. The Agency's goal is to be able
to
predict the potential of pesticides to cause harmful effects to
humans
and wildlife by using fewer laboratory animals as models and have
been
accepting data from alternative (to animals) test methods for several
years. As progress is made on finding or developing non-animal test
models that reliably predict the potential for harm to humans or
the
environment, EPA expects that it will need fewer animal studies
to make
safety determinations.
VI. Conclusion
Therefore, tolerances are established for residues of cyfluthrin
as
requested in the revised petitions.
[[Page 53952]]
VII. Objections and Hearing Requests
Under section 408(g) of FFDCA, as amended by FQPA, any person may
file an objection to any aspect of this regulation and may also
request
a hearing on those objections. The EPA procedural regulations which
govern the submission of objections and requests for hearings appear
in
40 CFR part 178. Although the procedures in those regulations require
some modification to reflect the amendments made to FFDCA by FQPA,
EPA
will continue to use those procedures, with appropriate adjustments,
until the necessary modifications can be made. The new section 408(g)
of FFDCA provides essentially the same process for persons to
``object'' to a regulation for an exemption from the requirement
of a
tolerance issued by EPA under new section 408(d) of FFDCA, as was
provided in the old sections 408 and 409 of FFDCA. However, the
period
for filing objections is now 60 days, rather than 30 days.
A. What Do I Need to Do to File an Objection or Request a Hearing?
You must file your objection or request a hearing on this
regulation in accordance with the instructions provided in this
unit
and in 40 CFR part 178. To ensure proper receipt by EPA, you must

Washington, DC 20005. The Office of the Hearing Clerk is open from
8
a.m. to 4 p.m., Monday through Friday, excluding legal holidays.
The
telephone number for the Office of the Hearing Clerk is (202) 564-6255.
2. Copies for the Docket. In addition to filing an objection or
hearing request with the Hearing Clerk as described in Unit VI.A.,
you
should also send a copy of your request to the PIRIB for its inclusion
in the official record that is described in ADDRESSES. Mail your
copies, identified by docket ID number OPP-2005-0205, to: Public
Information and Records Integrity Branch, Information Resources
and
Services Division (7502C), Office of Pesticide Programs, Environmental
Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-
0001. In person or by courier, bring a copy to the location of the
PIRIB described in ADDRESSES. You may also send an electronic copy
of
your request via e-mail to: opp-docket@epa.gov. Please use an ASCII
file format and avoid the use of special characters and any form
of
encryption. Copies of electronic objections and hearing requests
will
also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format.
Do not include any CBI in your electronic copy. You may also submit
an
electronic copy of your request at many Federal Depository Libraries.
B. When Will the Agency Grant a Request for a Hearing?
A request for a hearing will be granted if the Administrator
determines that the material submitted shows the following: There
is a
genuine and substantial issue of fact; there is a reasonable
possibility that available evidence identified by the requestor
would,
if established resolve one or more of such issues in favor of the
requestor, taking into account uncontested claims or facts to the
contrary; and resolution of the factual issues(s) in the manner
sought
by the requestor would be adequate to justify the action requested
(40
CFR 178.32).
VIII. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office
of
Management and Budget (OMB) has exempted these types of actions
from
review under Executive Order 12866, entitled Regulatory Planning
and
Review (58 FR 51735, October 4, 1993). Because this rule has been
exempted from review under Executive Order 12866 due to its lack
of
significance, this rule is not subject to Executive Order 13211,
Actions Concerning Regulations That Significantly Affect Energy
Supply,
Distribution, or Use (66 FR 28355, May 22, 2001). This final rule
does
not contain any information collections subject to OMB approval
under
the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose
any enforceable duty or contain any unfunded mandate as described
under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public
Law
104-4). Nor does it require any special considerations under Executive
Order 12898, entitledFederal Actions to Address Environmental Justice
in Minority Populations and Low-Income Populations (59 FR 7629,
February 16, 1994); or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental
Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). This action
does
not involve any technical standards that would require Agency
consideration of voluntary consensus standards pursuant to section
12(d) of the National Technology Transfer and Advancement Act of
1995
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note).
Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of FFDCA, such as the tolerance in
this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601et
seq.) do not apply. In addition, the Agency has determined that
this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or
on the
distribution of power and responsibilities among the various levels
of
government, as specified in Executive Order 13132, entitled Federalism
(64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA
to
develop an accountable process to ensure ``meaningful and timely
input
by State and local officials in the development of regulatory policies
that have federalism implications.''``Policies that have federalism
implications'' is defined in the Executive Order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or
on the
distribution of power and responsibilities among the various levels
of
government.'' This final rule directly regulates growers, food
processors, food handlers and food retailers, not States. This action
does not
[[Page 53953]]
alter the relationships or distribution of power and responsibilities
established by Congress in the preemption provisions of section
408(n)(4) of FFDCA. For these same reasons, the Agency has determined
that this rule does not have any ``tribal implications'' as described
in Executive Order 13175, entitled Consultation and Coordination
with
Indian Tribal Governments (59 FR 22951, November 6, 2000). Executive
Order 13175, requires EPA to develop an accountable process to ensure
``meaningful and timely input by tribal officials in the development
of
regulatory policies that have tribal implications.''``Policies that
have tribal implications'' is defined in the Executive Order to
include
regulations that have ``substantial direct effects on one or more
Indian tribes, on the relationship between the Federal Government
and
the Indian tribes, or on the distribution of power and responsibilities
between the Federal Government and Indian tribes.'' This rule will
not
have substantial direct effects on tribal governments, on the
relationship between the Federal Government and Indian tribes, or
on
the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this rule.
IX. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by
the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the
rule,
to each House of the Congress and to the Comptroller General of
the
United States. EPA will submit a report containing this rule and
other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States
prior
to publication of this final rule in the Federal Register. This
final
rule is not a ``major rule'' as defined by 5 U.S.C. 804(2).
