be amended by establishing tolerances
for residues of the fungicide
famoxadone, 3-anilino-5-methyl-5-(4phenoxyphenyl)-1,3-oxazolidine-2,4dione, in or on grape (east of the rocky
mountains) at 2.5 parts per million
(ppm); hop, dried cone at 60 ppm; and
caneberry at 11 ppm. These notices
referenced a summary of the petitions
prepared by Dupont, the registrant,
which is available to the public in the
docket, https://www.regulations.gov. A
comment was received from a private
citizen on the notice of filing for
famoxadone on caneberry. EPA’s
response to comment is discussed in
Unit IV.C.
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of the 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 the 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 the 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. . . .’’ These
provisions were added to the FFDCA by
the Food Quality Protection Act (FQPA)
of 1996.
Consistent with FFDCA section
408(b)(2)(D), and the factors specified in
section 408(b)(2)(D), EPA has reviewed
the available scientific data and other
relevant information in support of this
action. EPA has sufficient data to assess
the hazards of and to make a
determination on aggregate exposure for
the petitioned–for tolerances for
residues of famoxadone grape (regional
registration) at 2.5 ppm; hop, dried cone
at 80 ppm; and caneberry subgroup 13A
at 10 ppm on EPA’s assessment of
exposures and risks associated with
establishing the tolerances follow.
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
VerDate Aug<31>2005
15:35 May 22, 2007
Jkt 211001
studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children. Specific
information on the studies received and
the nature of the adverse effects caused
by famoxadone as well as the no
observed adverse effect level (NOAEL)
and the lowest observed adverse effect
level (LOAEL) from the toxicity studies
are discussed in the final rule published
in the Federal Register at https://
www.epa.gov/EPA–PEST/2003/July/
Day–02/p16736.htm.
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, the toxicological level of concern
(LOC) is derived from the highest dose
at which no adverse effects are observed
(the NOAEL) in the toxicology study
identified as appropriate for use in risk
assessment. However, if a NOAEL
cannot be determined, the lowest dose
at which adverse effects of concern are
identified (the LOAEL) is sometimes
used for risk assessment. Uncertainty/
safety factors (UF) are used in
conjunction with the LOC to take into
account 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. Safety is assessed for acute
and chronic risks by comparing
aggregate exposure to the pesticide to
the acute population adjusted dose
(aPAD) and chronic population adjusted
dose (cPAD). The aPAD and cPAD are
calculated by dividing the LOC by all
applicable uncertainty/safety factors.
Short-, intermediate, and long-term risks
are evaluated by comparing aggregate
exposure to the LOC to ensure that the
margin of exposure (MOE) called for by
the product of all applicable
uncertainty/safety factors is not
exceeded.
For non-threshold risks, the Agency
assumes that any amount of exposure
will lead to some degree of risk and
estimates risk in terms of the probability
of occurrence of additional adverse
cases. Generally, cancer risks are
considered non–threshold. 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/fedrgstr/EPA–PEST/1997/
November/Day–26/p30948.htm.

2006–0332.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to famoxadone, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing famoxadone tolerances in (40
CFR 180.587). EPA assessed dietary
exposures from famoxadone in food as
follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
are performed for a food-use pesticide,
if a toxicological study has indicated the
possibility of an effect of concern
occurring as a result of a 1–day or single
exposure. No such effects were
identified in the toxicological studies
for famoxadone. Therefore, a
quantitative acute dietary exposure
assessment was not performed.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 1994–1996 and 1998
Nationwide Continuing Surveys of Food
Intake by Individuals (CSFII). As to
residue levels in food, EPA used Dietary
Exposure Evaluation Model (DEEMTM)
default processing factors and
anticipated residues (ARs) calculated
from field trial data including the
highest average field trial (HAFT) level
for hop and caneberry, and existing ARs
for grape commodities. Exposure
estimates were further refined with
percent crop treated (PCT) data for
several registered commodities.
iii. Cancer. EPA has classified
famoxadone as a ‘‘not likely’’ human
carcinogen. Therefore, a cancer dietary
exposure analysis was not performed.
iv. Anticipated residue and 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 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. For the present
action, EPA will issue such Data CallIns as are required by section
408(b)(2)(E) of FFDCA and authorized
under section 408(f)(1) of FFDCA. Data
will be required to be submitted no later
than 5 years from the date of issuance
of this tolerance.

cprice-sewell on PROD1PC71 with RULES
Federal Register / Vol. 72, No. 99 / Wednesday, May 23, 2007 / Rules and Regulations
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:
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 such
pesticide residue;
b. The exposure estimate does not
underestimate exposure for any
significant subpopulation group; and
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 section 408(b)(2)(F)
of FFDCA, EPA may require registrants
to submit data on PCT.
The Agency used PCT information as
follows:
Tomato at 10%; Cucumber, Pepper,
Potato, Pumpkin at 5%; Squash and
Watermelon at 1%EPA uses an average
PCT for chronic dietary risk analysis.
The average PCT figure for each existing
use is derived by combining available
federal, state, and private market survey
data for that use, averaging by year,
averaging across all years, and rounding
up to the nearest multiple of five
percent 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 risk analysis. 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 percent. 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 believes that the three
conditions listed have been met. With
respect to Condition 1, 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 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
VerDate Aug<31>2005
15:35 May 22, 2007
Jkt 211001
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
famoxadone may be applied in a
particular area.
2. Dietary exposure from drinking
water. The Agency lacks sufficient
monitoring data to complete a
comprehensive dietary exposure
analysis and risk assessment for
famoxadone 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 environmental fate characteristics of
famoxadone. 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.
The assessment was based on the
registered potato use (highest
application rate, 0.1875 lbs ai/acre, with
6 applications at 5 day intervals). The
Pesticide Root Zone Model/Exposure
Analysis Modeling System (PRZM/
EXAMS) Model was used to estimate
surface water concentrations, and
Screening Concentrations in
Groundwater (SCI-GROW) Model was
used to estimate ground water
concentrations. The model values
generally represent upper-bound
estimates of the concentrations that
might be found in surface water and
ground water resulting from the use of
famoxadone.
Based on the PRZM/EXAMS and SCIGROW models, the estimated
environmental concentrations (EECs) of
famoxadone for chronic exposures are
estimated to be 0.47 ppb for surface
water and 0.23 ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
water concentration of value 0.47 ppb
was used to access 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,
PO 00000
Frm 00055
Fmt 4700
Sfmt 4700
28879
indoor pest control, termiticides, and
flea and tick control on pets).
Famoxadone is not registered for use
on any sites that would result in
residential exposure.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of the FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
famoxadone and any other substances
and famoxadone does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
not assumed that famoxadone has a
common mechanism of toxicity with
other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408 of FFDCA
provides that EPA shall apply an
additional (‘‘10X’’) 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. This additional
margin of safety is commonly referred to
as the FQPA safety factor. 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 FQPA
safety factor value based on the use of
traditional uncertainty/safety factors
and/or special FQPA safety factors, as
appropriate.
2. Prenatal and postnatal sensitivity.
There is no quantitative or qualitative
evidence of increased susceptibility of
rat and rabbit fetuses to in utero
exposure in developmental studies.
There is no quantitative or qualitative
evidence of increased susceptibility of
rat offspring in the multi-generation
reproduction study.

Federal Register / Vol. 72, No. 99 / Wednesday, May 23, 2007 / Rules and Regulations
cprice-sewell on PROD1PC71 with RULES
3. Conclusion. EPA has determined
that reliable data show that it would be
safe for infants and children to reduce
the FQPA safety factor to 1X. That
decision is based on the following
findings:
i. The toxicity database for
famoxadone is complete.
ii. There is no indication that
famoxadone is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional uncertainty factors to account
for neurotoxicity.
iii. There is no evidence that
famoxadone results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2–generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
Although the food exposure assessment
was slightly refined, it is based in
reliable data and will not underestimate
the exposure and risk. Conservative
ground water and surface water
modeling estimates were used. These
assessments will not underestimate the
exposure and risks posed by
famoxadone.
E. Aggregate Risks and Determination of
Safety
Safety is assessed for acute and
chronic risks by comparing aggregate
exposure to the pesticide to the aPAD
and cPAD. The aPAD and cPAD are
calculated by dividing the LOC by all
applicable uncertainty/safety factors.
For linear cancer risks, EPA calculates
the probability of additional cancer
cases given aggregate exposure. Short-,
intermediate, and long-term risks are
evaluated by comparing aggregate
exposure to the LOC to ensure that the
MOE called for by the product of all
applicable uncertainty/safety factors is
not exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account exposure
estimates from acute dietary
consumption and drinking water. There
was no acute dietary endpoint selected.
Therefore, famoxdane is not expected to
pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that exposure to famoxadone from food
and water will utilize 65% of the cPAD
for children 1-2 years old, the
subpopulation group with the greatest
exposure. There are no residential uses
for famoxadone that result in chronic
residential exposure to famoxadone.
3. Short and intermediate-term risks.
Short and Intermediate-term aggregate
exposures takes into account residential
VerDate Aug<31>2005
15:35 May 22, 2007
Jkt 211001
exposure plus chronic exposure to food
and water (considered to be a
background exposure level).
Famoxadone is not registered for use
on any sites that would result in
residential exposure. Therefore, the
aggregate risk is the sum of the risk from
food and water, which do not exceed
the Agency’s level of concern.
4. Aggregate cancer risk for U.S.
population. EPA has classified
famoxadone as a ‘‘not likely’’ human
carcinogen. Therefore, famoxdane is not
expected to pose a cancer risk.
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 famoxadone
residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An analytical method AMR 3705–95;
gas chromatography with nitrogen/
phosphorus detector (GC/NPD) for
plants was developed for data gathering
and enforcement purposes to quantitate
famoxadone. The method has
undergone a successful independent
laboratory validation (ILV) and Agency
petition method validation (PMV).
Therefore, adequate enforcement
methodology is available to enforce this
tolerance expression. The method may
be requested from: Chief, Analytical
Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
There are no established CODEX
maximum residue limits (MRLs) for
famoxadone.
C. Response to Comments
One comment was received by a
private citizen. The commenter argued
that cancer rates in the United States are
too high and no new pesticides should
be approved until the causes of the
increased cancers are found.
Additionally, the commenter urged that
EPA should test famoxdane in
combination with the thousands of
other chemicals to which humans are
exposed. Famoxdane has been
examined in the required
carcinogenicity studies and EPA
concluded that it is not likely to be
carcinogenic to humans. This was
discussed in a prior rulemaking
published in the Federal Register at
https://www.epa.gov/EPA-PEST/2003/
July/Day-02/p16736.htm. EPA does not
PO 00000

require the testing of pesticides in
combination with other chemicals but
does consider available data bearing on
whether a pesticide shares a common
toxicity with other substances that
could result in cumulative effects. For
specific information regarding EPA’s
approach to the use of common
mechanism of toxicity to evaluate the
cumulative effects of chemicals, please

see policy statements.
V. Conclusion
The proposed tolerance for hop, dried
cone was requested at 60 ppm. The
residue data from the hop field trials
indicate that residues of famoxadone
ranged from 14.70 ppm to 46.85 ppm in/
on dried hops harvested 7-8 days after
the last of six applications at a total rate
of ~1.50 lb ai/A. The submitted data are
adequate pending label revision to
reflect the parameters of field trial data.
The Agency recommends the following
label revisions: apply a maximum single
foliar application rate of 0.25 lb ai/A,
with a 6-8 day RTI, a maximum seasonal
rate of ~1.50 lb ai/A, and a 7–day PHI.
Statistical analysis of the data show that
a tolerance level of 80 ppm will be
appropriate for hops.
The proposed tolerance for caneberry,
subgroup 13-A was requested at 11
ppm. The results from these trials show
that famoxadone residues ranged from
0.40 ppm to 6.7 ppm on/in treated
caneberry when the test substance was
applied at the proposed seasonal
application rate of 1.125 lb ai/A using
a 0–day PHI. Caneberry were stored
frozen for a maximum of 181 days at
–21°9C. Submitted storage stability
studies indicate that famoxadone
residues are stable on caneberry for up
to 216 days. A residue decline study
was not conducted by the applicant.
Statistical analysis of the data show that
a tolerance level of 10 ppm will be
appropriate for caneberry, subgroup 13A.
Therefore, the tolerances are
established for residues of famoxadone,
3-anilino-5-methyl-5-(4phenoxyphenyl)-1,3-oxazolidine-2,4dione), in or on grape (regional
registration) at 2.5 ppm; hop, dried cone
at 80 ppm; and caneberry, Subgroup
13A at 10 ppm.
VI. 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

Federal Register / Vol. 72, No. 99 / Wednesday, May 23, 2007 / Rules and Regulations
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, 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) 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 section 408(d) of FFDCA, such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. 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 6, 2000) do not apply
to this rule. In addition, This 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)
(Pub. L. 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995

VII. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report to each House of
the Congress and to the Comptroller
General of the United States. EPA will
submit a report containing this rule and
other required information to the U.S.
Senate, the U.S. House of
Representatives, and the Comptroller
General of the United States prior to
publication of this final rule in the
Federal Register. This final rule is not
a ‘‘major rule’’ as defined by 5 U.S.C.

II. Petition for Tolerance
In the Federal Register of May 10, 2006 (71 FR 27247) (FRL-8067-5)
and November 22, 2006 (71 FR 67572) (FRL-8101-9), EPA issued notices
pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3),
announcing the filing of pesticide petitions PP 5E7001 (grape and hop),
and PP 6E7099 (caneberry) by the IR-4, 500 College Road East, Suite 201
W, Princeton, NJ 08540. The petitions requested that 40 CFR 180.587
[[Page 28878]]
be amended by establishing tolerances for residues of the fungicide
famoxadone, 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-
dione, in or on grape (east of the rocky mountains) at 2.5 parts per
million (ppm); hop, dried cone at 60 ppm; and caneberry at 11 ppm.
These notices referenced a summary of the petitions prepared by Dupont,
the registrant, which is available to the public in the docket, https://
www.regulations.gov. A comment was received from a private citizen on
the notice of filing for famoxadone on caneberry. EPA's response to
comment is discussed in Unit IV.C.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of the 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 the 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 the 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. . .
.'' These provisions were added to the FFDCA by the Food Quality
Protection Act (FQPA) of 1996.
Consistent with FFDCA section 408(b)(2)(D), and the factors
specified in section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for the petitioned-for tolerances
for residues of famoxadone grape (regional registration) at 2.5 ppm;
hop, dried cone at 80 ppm; and caneberry subgroup 13A at 10 ppm on
EPA's assessment of exposures and risks associated with establishing
the tolerances follow.
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. Specific information on the studies received and the nature
of the adverse effects caused by famoxadone as well as the no observed
adverse effect level (NOAEL) and the lowest observed adverse effect
level (LOAEL) from the toxicity studies are discussed in the final rule
published in the Federal Register at https://www.epa.gov/EPA-PEST/2003/
July/Day-02/p16736.htm.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, the toxicological level of concern (LOC) is derived
from the highest dose at which no adverse effects are observed (the
NOAEL) in the toxicology study identified as appropriate for use in
risk assessment. However, if a NOAEL cannot be determined, the lowest
dose at which adverse effects of concern are identified (the LOAEL) is
sometimes used for risk assessment. Uncertainty/safety factors (UF) are
used in conjunction with the LOC to take into account 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. Safety is assessed for acute and chronic
risks by comparing aggregate exposure to the pesticide to the acute
population adjusted dose (aPAD) and chronic population adjusted dose
(cPAD). The aPAD and cPAD are calculated by dividing the LOC by all
applicable uncertainty/safety factors. Short-, intermediate, and long-
term risks are evaluated by comparing aggregate exposure to the LOC to
ensure that the margin of exposure (MOE) called for by the product of
all applicable uncertainty/safety factors is not exceeded.
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk and estimates risk in terms
of the probability of occurrence of additional adverse cases.
Generally, cancer risks are considered non-threshold. 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/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
A summary of the toxicological endpoints for famoxadone can be
found at www.regulations.gov in the Human Health Risk Assessment for
Famoxadone to Support Tolerances for Residues in/on Grapes, Hops, and
Caneberry, Crop Subgroup 13A, pages 10-11 in Docket ID EPA-HQ-OPP-2006-
0332.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to famoxadone, EPA considered exposure under the petitioned-
for tolerances as well as all existing famoxadone tolerances in (40 CFR
180.587). EPA assessed dietary exposures from famoxadone in food as
follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure. No such effects were
identified in the toxicological studies for famoxadone. Therefore, a
quantitative acute dietary exposure assessment was not performed.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII). As to residue levels in food, EPA used Dietary Exposure
Evaluation Model (DEEM\TM\) default processing factors and anticipated
residues (ARs) calculated from field trial data including the highest
average field trial (HAFT) level for hop and caneberry, and existing
ARs for grape commodities. Exposure estimates were further refined with
percent crop treated (PCT) data for several registered commodities.
iii. Cancer. EPA has classified famoxadone as a ``not likely''
human carcinogen. Therefore, a cancer dietary exposure analysis was not
performed.
iv. Anticipated residue and 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 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. For the present action,
EPA will issue such Data Call-Ins as are required by section
408(b)(2)(E) of FFDCA and authorized under section 408(f)(1) of FFDCA.
Data will be required to be submitted no later than 5 years from the
date of issuance of this tolerance.
[[Page 28879]]
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:
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
such pesticide residue;
b. The exposure estimate does not underestimate exposure for any
significant subpopulation group; and
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 section 408(b)(2)(F)
of FFDCA, EPA may require registrants to submit data on PCT.
The Agency used PCT information as follows:
Tomato at 10%; Cucumber, Pepper, Potato, Pumpkin at 5%; Squash and
Watermelon at 1%EPA uses an average PCT for chronic dietary risk
analysis. The average PCT figure for each existing use is derived by
combining available federal, state, and private market survey data for
that use, averaging by year, averaging across all years, and rounding
up to the nearest multiple of five percent 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 risk analysis. 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 percent. 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 believes that the three conditions listed have been met.
With respect to Condition 1, 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 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 famoxadone may
be applied in a particular area.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring data to complete a comprehensive dietary exposure
analysis and risk assessment for famoxadone 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 environmental fate characteristics of
famoxadone. 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.
The assessment was based on the registered potato use (highest
application rate, 0.1875 lbs ai/acre, with 6 applications at 5 day
intervals). The Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) Model was used to estimate surface water
concentrations, and Screening Concentrations in Groundwater (SCI-GROW)
Model was used to estimate ground water concentrations. The model
values generally represent upper-bound estimates of the concentrations
that might be found in surface water and ground water resulting from
the use of famoxadone.
Based on the PRZM/EXAMS and SCI-GROW models, the estimated
environmental concentrations (EECs) of famoxadone for chronic exposures
are estimated to be 0.47 ppb for surface water and 0.23 ppb for ground
water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 0.47 ppb was used to
access 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).
Famoxadone is not registered for use on any sites that would result
in residential exposure.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to famoxadone and any other
substances and famoxadone does not appear to produce a toxic metabolite
produced by other substances. For the purposes of this tolerance
action, therefore, EPA has not assumed that famoxadone has a common
mechanism of toxicity with other substances. For information regarding
EPA's efforts to determine which chemicals have a common mechanism of
toxicity and to evaluate the cumulative effects of such chemicals, see
EPA's website at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional (``10X'') 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. This
additional margin of safety is commonly referred to as the FQPA safety
factor. 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 FQPA safety factor value based on the use of
traditional uncertainty/safety factors and/or special FQPA safety
factors, as appropriate.
2. Prenatal and postnatal sensitivity. There is no quantitative or
qualitative evidence of increased susceptibility of rat and rabbit
fetuses to in utero exposure in developmental studies. There is no
quantitative or qualitative evidence of increased susceptibility of rat
offspring in the multi-generation reproduction study.
[[Page 28880]]
3. Conclusion. EPA has determined that reliable data show that it
would be safe for infants and children to reduce the FQPA safety factor
to 1X. That decision is based on the following findings:
i. The toxicity database for famoxadone is complete.
ii. There is no indication that famoxadone is a neurotoxic chemical
and there is no need for a developmental neurotoxicity study or
additional uncertainty factors to account for neurotoxicity.
iii. There is no evidence that famoxadone results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. Although the food exposure assessment was slightly refined,
it is based in reliable data and will not underestimate the exposure
and risk. Conservative ground water and surface water modeling
estimates were used. These assessments will not underestimate the
exposure and risks posed by famoxadone.
E. Aggregate Risks and Determination of Safety
Safety is assessed for acute and chronic risks by comparing
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and
cPAD are calculated by dividing the LOC by all applicable uncertainty/
safety factors. For linear cancer risks, EPA calculates the probability
of additional cancer cases given aggregate exposure. Short-,
intermediate, and long-term risks are evaluated by comparing aggregate
exposure to the LOC to ensure that the MOE called for by the product of
all applicable uncertainty/safety factors is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute dietary consumption and drinking
water. There was no acute dietary endpoint selected. Therefore,
famoxdane is not expected to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
famoxadone from food and water will utilize 65% of the cPAD for
children 1-2 years old, the subpopulation group with the greatest
exposure. There are no residential uses for famoxadone that result in
chronic residential exposure to famoxadone.
3. Short and intermediate-term risks. Short and Intermediate-term
aggregate exposures takes into account residential exposure plus
chronic exposure to food and water (considered to be a background
exposure level).
Famoxadone is not registered for use on any sites that would result
in residential exposure. Therefore, the aggregate risk is the sum of
the risk from food and water, which do not exceed the Agency's level of
concern.
4. Aggregate cancer risk for U.S. population. EPA has classified
famoxadone as a ``not likely'' human carcinogen. Therefore, famoxdane
is not expected to pose a cancer risk.
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 famoxadone residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
An analytical method AMR 3705-95; gas chromatography with nitrogen/
phosphorus detector (GC/NPD) for plants was developed for data
gathering and enforcement purposes to quantitate famoxadone. The method
has undergone a successful independent laboratory validation (ILV) and
Agency petition method validation (PMV). Therefore, adequate
enforcement methodology is available to enforce this tolerance
expression. The method may be requested from: Chief, Analytical
Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address:
residuemethods@epa.gov.
B. International Residue Limits
There are no established CODEX maximum residue limits (MRLs) for
famoxadone.
C. Response to Comments
One comment was received by a private citizen. The commenter argued
that cancer rates in the United States are too high and no new
pesticides should be approved until the causes of the increased cancers
are found. Additionally, the commenter urged that EPA should test
famoxdane in combination with the thousands of other chemicals to which
humans are exposed. Famoxdane has been examined in the required
carcinogenicity studies and EPA concluded that it is not likely to be
carcinogenic to humans. This was discussed in a prior rulemaking
published in the Federal Register at https://www.epa.gov/EPA-PEST/2003/
July/Day-02/p16736.htm. EPA does not require the testing of pesticides
in combination with other chemicals but does consider available data
bearing on whether a pesticide shares a common toxicity with other
substances that could result in cumulative effects. For specific
information regarding EPA's approach to the use of common mechanism of
toxicity to evaluate the cumulative effects of chemicals, please refer
to EPA's website at https://www.epa.gov/pesticides/cumulative to see
policy statements.
V. Conclusion
The proposed tolerance for hop, dried cone was requested at 60 ppm.
The residue data from the hop field trials indicate that residues of
famoxadone ranged from 14.70 ppm to 46.85 ppm in/on dried hops
harvested 7-8 days after the last of six applications at a total rate
of ~1.50 lb ai/A. The submitted data are adequate pending label
revision to reflect the parameters of field trial data. The Agency
recommends the following label revisions: apply a maximum single foliar
application rate of 0.25 lb ai/A, with a 6-8 day RTI, a maximum
seasonal rate of ~1.50 lb ai/A, and a 7-day PHI. Statistical analysis
of the data show that a tolerance level of 80 ppm will be appropriate
for hops.
The proposed tolerance for caneberry, subgroup 13-A was requested
at 11 ppm. The results from these trials show that famoxadone residues
ranged from 0.40 ppm to 6.7 ppm on/in treated caneberry when the test
substance was applied at the proposed seasonal application rate of
1.125 lb ai/A using a 0-day PHI. Caneberry were stored frozen for a
maximum of 181 days at -21[deg]9C. Submitted storage stability studies
indicate that famoxadone residues are stable on caneberry for up to 216
days. A residue decline study was not conducted by the applicant.
Statistical analysis of the data show that a tolerance level of 10 ppm
will be appropriate for caneberry, subgroup 13-A.
Therefore, the tolerances are established for residues of
famoxadone, 3-anilino-5-methyl-5-(4-phenoxyphenyl)-1,3-oxazolidine-2,4-
dione), in or on grape (regional registration) at 2.5 ppm; hop, dried
cone at 80 ppm; and caneberry, Subgroup 13A at 10 ppm.
VI. 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
[[Page 28881]]
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, 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) 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 section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers and food retailers, not States or tribes, nor does this action
alter the relationships or distribution of power and responsibilities
established by Congress in the preemption provisions of section
408(n)(4) of FFDCA. As such, the Agency has determined that this action
will not have a substantial direct effect on States or tribal
governments, on the relationship between the national government and
the States or tribal governments, or on the distribution of power and
responsibilities among the various levels of government or between the
Federal Government and Indian tribes. 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 6,
2000) do not apply to this rule. In addition, This 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) (Pub. L.
104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Pub. L. 104-113, section 12(d) (15 U.S.C. 272
note).
VII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
