II. Background and Statutory Findings

In the Federal Register of May 3, 2006 (71 FR 26084) (FRL-8060-2),
EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of pesticide petitions (PP) 2F6371
and 5F4498 by Syngenta Crop Protection, Inc., and PP 6E4788, 7E4860,
and 8E4931 by Interregional Research Project No. 4 (IR-4). The
petitions requested that 40 CFR 180.434 be amended by establishing a
tolerance for combined residues of the fungicide propiconazole, 1-[[2-
(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl] methyl]-1H-1,2,4-
triazole and its metabolites determined as 2,4-dichlorobenzoic acid and
expressed as parent compound in or on leafy vegetables (Subgroup 4B) at
5.0 parts per million (ppm) (PP 6E4788); cranberry at 1.0 ppm (PP
7E4860); Mint at.3.0 ppm (PP 8E4931); and under PP 2F6371, almond,
hulls and onion, green at 8.0 ppm; berries (Group 13) and legume
vegetables (Group 6) at 1.0 ppm; foliage of legume vegetables (Group
7)/ sorghum/soybean, forage and sugar beet, tops at 10.0 ppm; carrot,
roots/pistachios/nuts, tree (Group 14) at 0.2 ppm; foliage of legume
vegetable (Group 7)/soybean, hay at 32.0 ppm; onion, dry bulb/corn,
grain/sugar beet, roots at 0.3 ppm; sorghum, grain/grain cereal group
(except corn, rice, and sorghum), bran at 2.5 ppm; sorghum, stover at
15.0 ppm; soybean, seed/grain, cereal group (except corn, rice, and
sorghum), hay/sugar beet, dried pulp at 2.0 ppm; strawberry at 1.5 ppm;
grain, cereal group (except corn, rice, and sorghum) (Group 15),

the petition requested existing tolerances be amended for corn, forage
at 4.0 ppm; corn, stover at 25.0 ppm; rice, grain at 7.0 ppm; and rice,
straw at 18.0 ppm. Additionally, PP 5F4498, requested inadvertent
residues for alfalfa, forage and hay at 0.1 ppm. That notice included a
summary of the petition prepared by Syngenta Crop Protection, Inc., the
registrant. There were no comments received in response to the notice
of filing.
Upon completing review of the current propiconazole database, the
Agency concluded that the appropriate tolerance levels for
propiconazole residues in or on pending crops and livestock commodities
should be established as follow: On grain, aspirated fractions at 30
ppm; almond, hulls at 7.0 ppm; barley, grain at 0.3 ppm; barley, hay at
1.4 ppm; barley, straw at 10 ppm; barley, bran at 0.6 ppm; cattle, fat
at 0.05 ppm; cattle, meat at 0.05 ppm; cattle, meat byproducts, except
liver and kidney at 0.05 ppm; leafy petioles, subgroup 4B at 5.0 ppm;
Berry group 13 at 1.0 ppm; carrot, roots at 0.25 ppm; corn, field,
forage at 12 ppm; corn, sweet, forage at 6.0 ppm; corn, field, grain at
0.2 ppm; corn, pop, grain at 0.2 ppm; corn, field, stover at 30 ppm;
corn, pop, stover at 30 ppm; corn, sweet, stover at 30 ppm; goat, fat

liver and kidney at 0.05 ppm; hog, kidney at 0.2 ppm; hog, liver at 0.2
ppm; horse, fat at 0.05 ppm; horse, meat at 0.05 ppm; horse, meat
byproducts, except liver and kidney at 0.05 ppm; spearmint, tops at 3.5
ppm; peppermint, tops at 3.5 ppm; oat, forage at 1.7 ppm; oat, grain at
0.3 ppm; oat, hay at 1.4 ppm; oat, straw at 10 ppm; onion, bulb at 0.2
ppm; onion, green at 9.0 ppm; pistachio at 0.1 ppm; rice, bran at 15
ppm; rice, grain at 7.0 ppm; rice, hulls at 20 ppm; rice, straw at 18
ppm; rye, grain at 0.3 ppm; rye, forage at 1.7 ppm; rye, straw at 10
ppm; rye, bran at 0.6 ppm; sorghum, grain, forage at 12 ppm; sorghum,
grain, grain at 3.5 ppm; sorghum, grain, stover at 15 ppm; sheep, fat
at 0.05 ppm; sheep, meat at 0.05 ppm; sheep, meat byproducts, except
liver and kidney at 0.05 ppm; soybean, forage at 11 ppm; soybean, hay
at 30 ppm; soybean, seed at 2.0 ppm; strawberry at 1.3 ppm; beet,
sugar, dried pulp at 1.0 ppm; beet, sugar, roots at 0.3 ppm; beet,

cranberry at 1.0 ppm; and inadvertent residues in or on alfalfa, forage
at 0.1 ppm and alfalfa, hay at 0.1 ppm. The Agency concluded that there
are insufficient data to establish tolerances legume vegetables (Group
6); foliage of legume vegetables (Group 7); cereal group (except corn,
rice, and sorghum) (Group 15). For additional information refer to
http://www.regulations.gov Docket No. EPA-HQ-OPP-2006-0347-0008.

EPA is also deleting several established tolerances in 40 CFR
180.434(a), (b), and (c) that are no longer needed as a result of this
action.
The revisions to 180.434(a) are as follows:
Delete celery at 5.0 ppm. Replaced with leafy petioles,
subgroup 4B at 5.0 ppm.
Delete pecans at 0.1 ppm. Replaced with nut, tree, group
14 at 0.1 ppm.
The revisions to 180.434(b) are as follows:
Delete the time-limited tolerance for blueberry at 1.0
ppm. Replaced with Berry group 13 at 1.0 ppm, under 40 CFR 180.434(a).
Delete the time-limited tolerance for cranberry; grain,
aspirated fractions; sorghum, grain, grain; sorghum, grain, stover;
soybean; soybean, forage; and soybean, hay. All are being replaced by
permanent tolerances.
Delete time-limited tolerance for dry bean; dry bean
forage; and dry bean hay since these tolerances have expired.
The revisions to 180.434(c) are as follows:
Delete mint, tops (leaves and stems) at 0.3 ppm. Replaced
with spearmint, tops at 3.5 ppm and peppermint, tops at 3.5 ppm under
40 CFR 180.434(a).
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical
residue....''
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm

action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure, consistent with section 408(b)(2)
of FFDCA, for a tolerance for combined residues of propiconazole and
its metabolites containing the dichlorobenzoic acid (DCBA) moiety

cranberry at 1.0 ppm; and inadvertent residues in or on alfalfa, forage
at 0.1 ppm and alfalfa, hay at 0.1 ppm. EPA's assessment of exposures
and risks associated with establishing the tolerance follows.

A. Toxicological Profile

EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children. Specific information on the studies received and the nature
of the toxic effects caused by propiconazole as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies can be found at
http://www.regulations.gov Docket No. EPA-HQ-OPP-2006-0347-0005; pages 35-42.

B. Toxicological Endpoints

For hazards that have a threshold below which there is no
appreciable risk, the dose at which no adverse effects are observed
(the NOAEL) from the toxicology study identified as appropriate for use
in risk assessment is used to estimate the toxicological level of
concern (LOC). However, the lowest dose at which adverse effects of
concern are identified (the LOAEL) is sometimes used for risk
assessment if no NOAEL was achieved in the toxicology study selected.
An uncertainty factor (UF) is applied to reflect uncertainties inherent
in the extrapolation from laboratory animal data to humans and in the
variations in sensitivity among members of the human population as well
as other unknowns.
The linear default risk methodology (Q*) is the primary method
currently used by the Agency to quantify non-threshold hazards such as
cancer. The Q* approach assumes that any amount of exposure will lead
to some degree of cancer risk, estimates risk in terms of the
probability of occurrence of additional cancer cases. More information
can be found on the general principles EPA uses in risk
characterization at http://www.epa.gov/pesticides/health/human.htm.

A summary of the toxicological endpoints for propiconazole used for
human risk assessment is discussed at http://www.regulations.gov Docket No.

EPA-HQ-OPP-2006-0347-0004; pages 23-25.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. Tolerances have been
established (40 CFR 180.434) for the combined residues of propiconazole
and its metabolites containing the dichlorobenzoic acid (DCBA) moiety
expressed as parent compound, in or on a variety of raw agricultural
commodities. Tolerances are also established for residues of
propiconazole and its metabolites containing the dichlorobenzoic acid
(DCBA) moiety expressed as parent compound in or on milk as well as
fat, meat, kidney, liver and meat by products of cattle, goats, hogs,
horse, and sheep. Some of these existing tolerances are being revised
as a result of this action. Risk assessments were conducted by EPA to
assess dietary exposures from propiconazole 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.
In conducting the acute dietary exposure assessment EPA used the
Dietary Exposure Evaluation Model software with the Food Commodity
Intake Database (DEEM-FCID\TM\), which incorporates food consumption
data as reported by respondents in the 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:
Tolerance levels and one hundred percent of the crops were treated for
all proposed new uses, revised uses, and existing uses.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the DEEM-FCID\TM\, 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: Tolerance levels and 100% of the crops were
treated for all proposed new uses, revised uses, and existing uses.
iii. Cancer. Propiconazole has been classified as a group C
(possible human carcinogen). The Agency concluded that the chronic risk
assessment, making use of the chronic population adjusted dose (cPAD),
is protective of any potential carcinogenic risk.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring exposure data to complete a comprehensive dietary
exposure analysis and risk assessment for propiconazole 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 propiconazole. Further information regarding EPA
drinking water models used in pesticide exposure assessment

[[Page 55303]]

can be found at http://www.epa.gov/oppefed1/models/water/index.htm.

A registrant drinking water monitoring study showed very few
detections among a total of 38 selected community water systems in 12
states. The Agency concluded that the sampling scheduling of this
monitoring study is not rigorous enough to be used for water
assessment. Since the monitoring studies did not provide good quality
data, this drinking water assessment is based on the model predicted
drinking water concentrations.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening concentration in Ground Water (SCI-
GROW) models, the estimated environmental concentrations (EECs) of
propiconazole for acute exposures are estimated to be 55.8 parts per
billion (ppb) for surface water and 0.64 ppb for ground water. The EECs
for chronic exposures are estimated to be 21.6 ppb for surface water
and 0.64 ppb for ground water.
To estimate surface water for each specific use, the maximum
allowable label rate was input into PRZM/EXAMS. The output
concentrations were without percent cropped area (PCA) consideration.
The final estimated drinking water concentrations were then adjusted
with the proper PCA. Except the uses of soybean (0.41 ppb) and wheat
(0.56 ppb), other uses assume the default PCA of 0.87 ppb. Among these
modeling results, turf use gives the highest acute concentration of
55.78 ppb (Microgram/liter ([micro]g/L)). For the chronic exposure,
turf use has the highest concentration of 21.61 ppb ([micro]g/L).
The EECs in ground water were calculated using the Tier I SCI-GROW
model. SCI-GROW is neither scenario- nor crop-specific. The only input
requirements are application rate, number of applications,
Koc, and aerobic soil metabolism half-life. The higher
estimated concentrations are associated with the higher rate. Turf use
has the highest concentration of 0.64 [micro]g/L (ppb). Modeled
estimates of drinking water concentrations were directly entered into
the dietary exposure model (DEEM-FCID(\TM\)). For acute dietary risk
assessment, the peak water concentration value of 55.8 ppb was used to
access the contribution to drinking water. For chronic dietary risk
assessment, the annual average concentration of 21.6 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).
Propiconazole is currently registered for use on the following
residential non-dietary sites: Ground covers; turf and ornamentals in
lawns and golf courses; ornamentals trees (injection); shade trees
(outdoor spray); herbaceous plants; ornamental woody shrubs and vines
and antimicrobial uses in paint and wood protection treatment. The risk
assessment was conducted using the following residential exposure
assumptions:
Homeowners can be exposed to propiconazole through dermal and
inhalation routes while applying home use products. All risk
calculations were conducted using the maximum turf application rate
(1.8 lb ai/acre). The anticipated use patterns and current labeling
indicate three major residential exposure scenarios based on the types
of equipment and techniques that can potentially be used to make
propiconazole applications. The quantitative exposure/risk assessment
developed for residential handlers is based on these scenarios:
Mixer/Loader/applying liquids and wettable powder in water
soluble packets via low pressure handwand.
Mixer/Loader/applying liquids and wettable powder in water
soluble packets via hose-end sprayer.
Applying treated paint using airless sprayer and hose-end
spray.
Residential handler exposure scenarios are considered to be short-
term only due to the infrequent uses associated with homeowner
products.
The existing residential use patterns result in post application
dermal exposures to adults, and dermal and oral exposures to infants
and children. These exposure scenarios are considered short term only,
due to the fact that:
i. Post-application exposures were calculated using propiconazole
as the parent compound;
ii. Compound specific turf transferable residue (TTR) data indicate
that at the Indiana, California, and Pennsylvania test sites, average
total propiconazole residues declined to below the minimum quantifiable
limit (MQL) by 14, 10 and 8 days after treatment, respectively. These
dissipation rates, combined with label specific use rates and frequency
of use specifications, reinforce the hand to mouth short-term exposure
scenario;
iii. For short term exposure to children 1-2 years old, the driving
factors for this risk assessment are hand to mouth, object to mouth,
and dermal exposure. Soil ingestion is insignificant (margin of
exposure (MOE) >300,000) compared to these factors, indicating that the
post application scenario should be short term only. Although both
residential and antimicrobial uses result in incidental oral and dermal
exposure to children, the highest incidental oral and dermal exposure
scenarios are from residential use on turf, which were used in the
short term aggregate risk assessment.
In addition to using the EPA's Standard Operational Procedure (SOP)
for residential assessment, the study specific turf transferable
residue (TTR) was used to estimate exposures. The EPA combined
exposures resulting from separate post-application exposure scenarios
when it is likely they can occur simultaneously based on the use-
pattern and the behavior associated with the exposed population. The
assumptions used for each of the scenarios separately are considered to
account for potential high levels of exposure (i.e., time spent
outdoors, dislodgeable residues) therefore, combining all these
activities together is considered a very high end estimate of exposure.
Propiconazole is classified as a non-volatile chemical; therefore a
residential inhalation post-application assessment was not assessed.
The only residential use scenario that will result in potential
intermediate term exposure to propiconazole is post application
exposure to children from wood treatment (antimicrobial use) from
incidental oral and dermal contact activities.
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.''
Propiconazole is a member of the triazole-containing class of
pesticides. Although conazoles act similarly in plants (fungi) by
inhibiting ergosterol biosynthesis, there is not necessarily a
relationship between this pesticidal activity and their mechanism of
toxicity in mammals. Structural similarities do not constitute a common
mechanism of toxicity. Evidence is needed to establish that the
chemicals operate by the same, or essentially the same sequence of
major biochemical events (EPA, 2002). In conazoles, however, a variable
pattern of toxicological responses is found. Some are hepatotoxic and
hepatocarcinogenic in mice. Some

[[Page 55304]]

induce thyroid tumors in rats. Some induce developmental, reproductive,
and neurological effects in rodents. Furthermore, the conazoles produce
a diverse range of biochemical events including altered cholesterol
levels, stress responses, and altered DNA methylation. It is not
clearly understood whether these biochemical events are directly
connected to their toxicological outcomes. Thus, there is currently no
evidence to indicate that conazoles share common mechanisms of toxicity
and EPA is not following a cumulative risk approach based on a common
mechanism of toxicity for the conazoles. For information regarding
EPA's procedures for cumulating effects from substances found to have a
common mechanism of toxicity, see EPA's website at http://www.epa.gov/pesticides/cumulative
.

Propiconazole is a triazole-derived pesticide. This class of
compounds can form the common metabolite 1,2,4-triazole conjugates
(triazole alanine and triazole acetic acid). To support existing
tolerances and to establish new tolerances for triazole-derivative
pesticides, including propiconazole, EPA conducted a human health risk
assessment for exposure to 1,2,4-triazole, triazole alanine, and
triazole acetic acid resulting from the use of all current and pending
uses of any triazole-derived fungicide. The risk assessment is highly
conservative, screening-level evaluation in terms of hazards associated
with common metabolites (e.g., use of a maximum combination of
uncertainty factors) and potential dietary and non-dietary exposures
(i.e., high end estimates of both dietary and non-dietary exposures).
In addition, the Agency retained the additional 10X FQPA safety factor
for the protection of infants and children. The assessment includes
evaluations of risks for various subgroups, including those comprised
of infants and children. The Agency's complete risk assessment is found
in the propiconazole reregistration docket at http://www.regulations.gov,

Docket ID number EPA-HQ-OPP-2005-0497-0013.

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 database on toxicity and exposure
unless EPA determines based on reliable data that a different margin of
safety will be safe for infants and children. Margins of safety are
incorporated into EPA risk assessments either directly through use of a
MOE analysis or through using uncertainty (safety) factors in
calculating a dose level that poses no appreciable risk to humans. In
applying this provision, EPA either retains the default value of 10X
when reliable data do not support the choice of a different factor, or,
if reliable data are available, EPA uses a different additional safety
factor value based on the use of traditional uncertainty factors and/or
special FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There is low concern for
pre- and/or postnatal toxicity resulting from exposure to
propiconazole. In the developmental toxicity study in rats, the EPA
considered the fetal effects observed in this study at a dose lower
than that evoking maternal toxicity to be quantitative evidence of
increased susceptibility of fetuses to in utero exposure to
propiconazole. In the developmental toxicity study in rabbits, the
Agency determined that neither quantitative nor qualitative evidence of
increased susceptibility of fetuses to in utero exposure to
propiconazole was observed in this study. In the 2-generation
reproduction study in rats, neither quantitative nor qualitative
evidence of increased susceptibility of neonates (as compared to
adults) to pre- and/or postnatal exposure to propiconazole was observed
in the study. Since there is quantitative evidence of increased
susceptibility of the young following exposure to propiconazole in the
developmental rat study, the Agency performed a Degree of Concern
Analysis to:
i. Determine the LOC for the effects observed when considered in
the context of all available toxicity data; and
ii. Identify any residual uncertainties after establishing toxicity
endpoints and traditional uncertainty factors to be used in the risk
assessment of this chemical. If residual uncertainties are identified,
then EPA examines whether these residual uncertainties can be addressed
by a special FQPA safety factor and, if so, the size of the factor
needed. In the developmental rat study, quantitative susceptibility was
evidenced as increased incidence of rudimentary ribs, unossified
sternebrae, as well as increased incidence of shortened and absent
renal papillae and increased cleft palate at (90 mg/kg/day) a dose
lower than that evoking maternal toxicity (severe clinical toxicity at
300 mg/kg/day). Considering the overall toxicity profile and the doses
and endpoints selected for risk assessment for propiconazole, the EPA
characterized the degree of concern for the effects observed in this
study as low, noting that there is a clear no observed adverse effect
level (NOAEL) and well-characterized dose response for the
developmental effects observed. No residual uncertainties were
identified. The NOAEL for developmental effects in this study (30 mg/
kg/day) is used as the basis for the acute Reference dose (aRfD) for
the female 13-50 population subgroup as well as for short-term
incidental oral, dermal and inhalation endpoints. For all other
toxicity endpoints established for propiconazole, a NOAEL lower than
this developmental NOAEL is used.
3. Conclusion. There is a complete toxicity data base for
propiconazole and exposure data are complete or are estimated based on
data that reasonably accounts for potential exposures. There is low
concern for pre- and/or postnatal toxicity resulting from exposure to
propiconazole. In the developmental toxicity study in rats the fetal
effects observed were seen at a dose lower than that evoking maternal
toxicity. These effects were considered to be quantitative evidence of
increased susceptibility of fetuses to in utero exposure to
propiconazole. Therefore, as discussed above a Degree of Concern
Analysis was conducted and the EPA concluded that the degree of concern
for the effects observed in this study was low and no residual
uncertainties were identified. EPA determined that the 10X SF to
protect infants and children should be removed.

E. Aggregate Risks and Determination of Safety

1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to propiconazole will occupy 6% of the acute Population Adjusted Dose
(aPAD) for the U.S. population, 5% of the aPAD for females 13 years and
older, 14% of the aPAD for all infants (< 1 year old), the subpopulation
at greatest exposure, and 13% of the aPAD for children 1-2 years old.
Therefore, EPA does not expect the aggregate exposure to exceed 100% of
the aPAD.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
propiconazole from food and water will utilize 6% of the chronic
Population Adjusted Dose (cPAD) for the U.S. population, 14% of the
cPAD for all infants (< 1 year old), and 14% of the cPAD for children 1-
2 years old, the subpopulation at greatest exposure. Based the use
pattern, chronic residential exposure to residues of propiconazole is
not expected.

[[Page 55305]]

Therefore, EPA does not expect the aggregate exposure to exceed 100%
of the cPAD.
3. Short-term risk. Short-term aggregate exposure takes into
account residential exposure plus chronic exposure to food and water
(considered to be a background exposure level).
Propiconazole 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 propiconazole.
Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded that food, water and residential
exposures aggregated result in aggregate MOEs for children 1-2 years
old of 1,100 for hand to mouth activity on turf; 4,500 for object to
mouth activity on turf; 330,000 for soil ingestion; 210 for high
contact turf activities; and 410 from the antimicrobial use of
propiconazole in treated wood. The food, water and residential
exposures aggregated for children 1-2 years old following post-
application of propiconazole result in an aggregate MOE of 160 for high
contact activities. The corresponding aggregate MOE for adults
following post-application exposure is 330. These aggregate MOEs do not
exceed the Agency's LOC for aggregate exposure to food, water and
residential uses. Therefore, EPA does not expect short-term aggregate
exposure to exceed the Agency's LOC.
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).
Propiconazole is currently registered for use(s) that could result
in intermediate-term residential exposure and the Agency has determined
that it is appropriate to aggregate chronic food and water and
intermediate-term exposures for propiconazole.
Using the exposure assumptions described in this unit for
intermediate-term exposures, EPA has concluded that food, water and
residential exposures aggregated result in an aggregate MOE of 120 for
combined exposures from incidental oral and dermal contact activities
for children 1-2 years old. These aggregate MOEs do not exceed the
Agency's LOC for aggregate exposure to food, water and residential
uses. Therefore, EPA does not expect intermediate-term aggregate
exposure to exceed the Agency's LOC.
5. Aggregate cancer risk for U.S. population. The Agency considers
the chronic aggregate risk assessment, making use of the cPAD, to be
protective of any aggregate cancer risk. See Unit III.E.2.
6. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, and to infants and children from aggregate
exposure to propiconazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology (a gas chromatography (GC) method
using electron capture detection (Method AG-454) is available to
enforce the tolerance expression. The method may be requested from:
Chief, Analytical Chemistry Branch, Environmental Science Center, 701
Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905;
e-mail address: residuemethods@epa.gov.

B. International Residue Limits

The Codex Alimentarius Commission has established several maximum
residue limits (MRLs) for propiconazole in/on various raw agricultural
commodities. The Codex MRLs are expressed in terms of propiconazole per
se. In addition, both Canada and Mexico have established MRLs/
tolerances on several commodities which also have U.S. tolerances. The
U.S. tolerance expression includes all metabolites determined as 2,4-
dichloro-benzoic acid. In conjunction with the reregistration process
EPA intends to revise the expression to propiconazole per se. To the
extent possible, for the present petitions, U.S. tolerances have been
numerically harmonized with Codex, Canadian, and Mexican MRLs; however,
differences in use patterns and the supporting residue data have
precluded reducing many tolerances. A summary of Codex MRLs, Canadian
MRLs, and Mexican tolerances and the corresponding U.S. tolerances for
propiconazole is discussed at http://www.regulations.gov Docket No. EPA-HQ-

OPP-2006-0347-0004; pages 53-54.

V. Conclusion

Therefore, tolerances are established for combined residues of
propiconazole and its metabolites containing the dichlorobenzoic acid
(DCBA) moiety expressed as parent compound in or on grain, aspirated
fractions at 30 ppm; almond, hulls at 7.0 ppm; barley, grain at 0.3

ppm; rice, straw at 18 ppm; rye, grain at 0.3 ppm; rye, forage at 1.7
ppm; rye, straw at 10 ppm; rye, bran at 0.6 ppm; sorghum, grain, forage
at 12 ppm; sorghum, grain, grain at 3.5 ppm; sorghum, grain, stover at
15 ppm; sheep, fat at 0.05 ppm; sheep, meat at 0.05 ppm; sheep, meat
byproducts, except liver and kidney at 0.05 ppm; soybean, forage at 11
ppm; soybean, hay at 30 ppm; soybean, seed at 2.0 ppm; strawberry at
1.3 ppm; beet, sugar, dried pulp at 1.0 ppm; beet, sugar, roots at 0.3

at 1.7 ppm; wheat, grain at 0.3 ppm; wheat, hay at 1.4 ppm; wheat,
straw at 10 ppm; cranberry at 1.0 ppm; and inadvertent residues in or
on alfalfa, forage at 0.1 ppm and alfalfa, hay at 0.1 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 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

[[Page 55306]]

enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law
104-4). Nor does it require any special considerations under Executive
Order 12898, entitled Federal Actions to Address Environmental Justice
in Minority Populations and Low-Income Populations (59 FR 7629,
February 16, 1994); or OMB review or any Agency action under Executive
Order 13045, entitled Protection of Children from Environmental Health
Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does
not involve any technical standards that would require Agency
consideration of voluntary consensus standards pursuant to section
12(d) of the National Technology Transfer and Advancement Act of 1995
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since
tolerances and exemptions that are established on the basis of a
petition under section 408(d) of FFDCA, such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply. In addition, the Agency has determined that this
action will not have a substantial direct effect on States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, entitled
Federalism(64 FR 43255, August 10, 1999). Executive Order 13132
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by State and local officials in the development of
regulatory policies that have federalism implications.'' ``Policies
that have federalism implications'' is defined in the Executive order
to include regulations that have ``substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government.'' This final rule directly regulates
growers, food processors, food handlers and food retailers, not States.
This action does not alter the relationships or distribution of power
and responsibilities established by Congress in the preemption
provisions of section 408(n)(4) of FFDCA. For these same reasons, the
Agency has determined that this rule does not have any ``tribal
implications'' as described in Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 6, 2000). Executive Order 13175, requires EPA to
develop an accountable process to ensure ``meaningful and timely input
by tribal officials in the development of regulatory policies that have
tribal implications.'' ``Policies that have tribal implications'' is
defined in the Executive order to include regulations that have
``substantial direct effects on one or more Indian tribes, on the
relationship between the Federal Government and the Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes.'' This rule will not have substantial
direct effects on tribal governments, on the relationship between the
Federal Government and Indian tribes, or on the distribution of power
and responsibilities between the Federal Government and Indian tribes,
as specified in Executive Order 13175. Thus, Executive Order 13175 does
not apply to this rule.

VII. 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).
