For the reasons set out in the
preamble, part 59 of Title 40 of the Code
of Federal Regulations is amended as
follows:
I
PART 59—[AMENDED]
Executive Order 12898 (59 FR 7629,
Feb. 16, 1994) establishes federal
executive policy on environmental
justice. Its main provision directs
federal agencies, to the greatest extent
practicable and permitted by law, to
make environmental justice part of their
mission by identifying and addressing,
as appropriate, disproportionately high
and adverse human health or
environmental effects of their programs,
policies, and activities on minority
populations and low-income
populations in the United States.
EPA has determined that this final
rule will not have disproportionately
high and adverse human health or
environmental effects on minority or
low-income populations because it
increases the level of environmental
protection for all affected populations
without having any disproportionately
high and adverse human health or
environmental effects on any
population, including any minority or
low-income populations. Further, it

and October 24, 2007 (72 FR 60369)
(FRL–8150–8), 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 6E7165,
PP 6F7105 and PP 7E7245) by
Interregional Research Project Number 4
(IR–4), 500 College Road East, Suite
201W, Princeton, NJ 08540 and BASF
Corporation, P.O. Box 13528, Research

comments received in response to the
April 4, 2007 or October 24, 2007
notices of filing; comments were
received from a private citizen in
response to the May 9, 2007 notice of
filing of pesticide petition 6F7105.
EPA’s response to these comments is
discussed in Unit IV.C.
IR–4 has withdrawn its request for a
tolerance for combined residues of
pyraclostrobin and its desmethoxy
metabolite in or on fresh herbs; and EPA
is deferring to a later date the decision
regarding the proposed tolerances in or
on oilseed commodities. Based upon
review of the data supporting the
E:\FR\FM\24MRR1.SGM
24MRR1
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
petitions, EPA has revised the tolerance
levels for the remaining commodities.
The reason for these changes is
explained in Unit IV.D.
pwalker on PROD1PC71 with RULES
III. Aggregate Risk Assessment and
Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA
allows EPA to establish a tolerance (the
legal limit for a pesticide chemical
residue in or on a food) only if EPA
determines that the tolerance is ‘‘safe.’’
Section 408(b)(2)(A)(ii) of FFDCA
defines ‘‘safe’’ to mean that ‘‘there is a
reasonable certainty that no harm will
result from aggregate exposure to the
pesticide chemical residue, including
all anticipated dietary exposures and all
other exposures for which there is
reliable information.’’ This includes
exposure through drinking water and in
residential settings, but does not include
occupational exposure. Section
408(b)(2)(C) of FFDCA requires EPA to
give special consideration to exposure
of infants and children to the pesticide
chemical residue in establishing a
tolerance and to ‘‘ensure that there is a
reasonable certainty that no harm will
result to infants and children from
aggregate exposure to the pesticide
chemical residue. . . .’’ These provisions
were added to FFDCA by the Food
Quality Protection Act (FQPA) of 1996.
Consistent with section 408(b)(2)(D)
of FFDCA, and the factors specified in
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 for the petitioned-for
tolerances for combined residues of
pyraclostrobin and its desmethoxy
metabolite on avocado at 0.6 ppm;
barley, grain at 1.4 ppm; canistel at 0.6
ppm; mango at 0.6 ppm; oat, grain at 1.2
ppm; oat, hay at 18 ppm; oat, straw at
15 ppm; papaya at 0.6 ppm; sapodilla at
0.6 ppm; sapote, black at 0.6 ppm;
sapote, mamey at 0.6 ppm; and star
apple at 0.6 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.
Pyraclostrobin has low to moderate
acute toxicity. In repeated dose oral
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
toxicity studies, the main target organs
for pyraclostrobin are the upper
gastrointestinal tract (mainly the
duodenum and stomach), the spleen/
hematopoiesis, the immune system, and
the liver. There was no evidence of
increased quantitative or qualitative
susceptibility of in utero rats or
offspring following exposure to
pyraclostrobin in the rat developmental
or reproduction toxicity studies. There
was evidence of increased qualitative
susceptibility of in utero rabbits
following exposure to pyraclostrobin in
the rabbit developmental study.
Increases in resorptions/litter and postimplantation losses occurred at doses
that resulted in less severe maternal
toxicity (decreases in body weight gain
and food consumption). In both the
acute and subchronic neurotoxicity
studies, there were no indications of
treatment-related neurotoxicity.
EPA has evaluated the carcinogenic
potential of pyraclostrobin and
concluded that, in accordance with the
EPA’s Final Guidelines for Carcinogen
Risk Assessment (March 2005),
pyraclostrobin should be classified into
the category ‘‘Not Likely to be
Carcinogenic to Humans.’’ This
determination is based on no treatmentrelated increase in tumors in either sex
of rats and mice, which were tested at
doses that were adequate to assess
carcinogenicity, and the lack of
evidence of mutagenicity.
Specific information on the studies
received and the nature of the adverse
effects caused by pyraclostrobin as well
as the no-observed-adverse-effect-level
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://

this action, which is described under
ADDRESSES, and is identified as EPA–
HQ–OPP–2007–0906–0003 in that
docket.
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
PO 00000
Frm 00041
Fmt 4700
Sfmt 4700
15427
(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 (UFs) 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 UFs. 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 UFs 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/pesticides/factsheets/
riskassess.htm.

endpoints for pyraclostrobin used for

OPP–2007–0003.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to pyraclostrobin, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing pyraclostrobin tolerances in 40
CFR 180.582. EPA assessed dietary
E:\FR\FM\24MRR1.SGM
24MRR1
pwalker on PROD1PC71 with RULES
15428
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
exposures from pyraclostrobin 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. EPA identified such an effect
for the general population (decreased
body weight gain seen after a single oral
dose in the rat acute neurotoxicity
study) and for females 13 to 49 years old
(increased resorptions/litter and
increased total resorptions seen in the
rabbit developmental toxicity study that
are presumed to occur after a single
exposure). The aPAD for the general
population has been established at 3.0
milligrams/kilogram/day (mg/kg/day);
whereas, the aPAD for females 13 to 49
years old is significantly lower (0.05
mg/kg/day), due to the more sensitive
endpoint on which it is based.
In estimating acute dietary exposure,
EPA used food consumption
information from the U.S. Department of
Agriculture (USDA) 1994–1996 and
1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). As
to residue levels in food, EPA assumed
that residues are present at tolerance
levels or for some commodities
(amaranth, leafy; arugula;
chrysanthemum; cress, garden; cress,
upland; dandelion, leaves; fennel;
parsley, leaves; radicchio; rhubarb;
spinach; swiss chard; beans, dry; celery;
lettuce, head; lettuce, leaf; and pea, dry)
at the highest residue level found in
residue field trials. One hundred
percent crop treated (PCT) was assumed
for all commodities in the assessment.
Default processing factors were applied
to all commodities except those for
which experimentally-derived
processing factors were available: apple
juice, grape juice, citrus juices,
cottonseed oil, tomato paste, tomato
puree, wheat flour, and wheat germ.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 1994–1996 and 1998
CSFII. As to residue levels in food, EPA
assumed that residues are present at
tolerance levels in all crops except
apple, broccoli, celery, collard, grape,
lettuce, citrus, pepper, mustard green
and tomato. EPA relied on anticipated
residues (average residues from field
trials) for these crops. One hundred PCT
was assumed for all commodities in the
assessment. Default processing factors
were applied to all commodities except
those for which experimentally-derived
processing factors were available: apple
juice, grape juice, citrus juices, tomato
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
paste, tomato puree, wheat flour, and
wheat germ.
iii. Cancer. Based on the results of
carcinogenicity studies in rats and mice,
EPA has concluded that pyraclostrobin
is ‘‘not likely to be carcinogenic to
humans.’’ Consequently, a quantitative
cancer exposure and risk assessment is
not appropriate for pyraclostrobin.
iv. Anticipated residue 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) of FFDCA,
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.
2. Dietary exposure from drinking
water. The Agency lacks sufficient
monitoring data to complete a
comprehensive dietary exposure
analysis and risk assessment for
pyraclostrobin 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
pyraclostrobin. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www.epa.gov/
oppefed1/models/water/index.htm.
Based on the 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
pyraclostrobin for acute exposures are
estimated to be 35.6 parts per billion
(ppb) for surface water and 0.02 ppb for
ground water. The EECs for chronic
exposures are estimated to be 2.3 ppb
for surface water and 0.02 ppb for
ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
acute dietary risk assessment, the water
concentration value of 35.6 ppb was
used to assess the contribution to
drinking water. For chronic dietary risk
assessment, the water concentration
PO 00000
Frm 00042
Fmt 4700
Sfmt 4700
value of 2.3 ppb was used to assess the
contribution to drinking water.
3. From non-dietary exposure. The
term ‘‘residential exposure’’ is used in
this document to refer to nonoccupational, non-dietary exposure
(e.g., for lawn and garden pest control,
indoor pest control, termiticides, and
flea and tick control on pets).
Pyraclostrobin is currently registered
for the following residential non-dietary
sites: Residential and recreational
turfgrass. EPA assessed residential
exposure using the following
assumptions: Residential and
recreational turf applications are
applied by professional pest control
operators (PCOs) only, and, therefore,
residential handler exposures do not
occur. There is, however, a potential for
short- and intermediate-term
postapplication exposure of adults and
children entering lawn and recreation
areas previously treated with
pyraclostrobin. Exposures from treated
recreational sites are expected to be
similar to, or in many cases lower than,
those from treated residential turf sites;
therefore, a separate exposure
assessment for recreational turf sites
was not conducted. EPA assessed
exposures from the following residential
turf postapplication scenarios:
i. Adult and toddler postapplication
dermal exposure from contact with
treated lawns,
ii. Toddlers’ incidental ingestion of
pesticide residues on lawns from handto-mouth transfer,
iii. Toddlers’ object-to-mouth transfer
from mouthing of pesticide-treated
turfgrass, and
iv. Toddlers’ incidental ingestion of
soil from pesticide-treated residential
areas. The postapplication risk
assessment was conducted in
accordance with the Residential
Standard Operating Procedures (SOPs)
and recommended approaches of the
Health Effects Division’s (HED’s)
Science Advisory Council for Exposure
(ExpoSAC).
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
Unlike other pesticides for which EPA
has followed a cumulative risk approach
based on a common mechanism of
toxicity, EPA has not made a common
mechanism of toxicity finding as to
pyraclostrobin and any other substances
E:\FR\FM\24MRR1.SGM
24MRR1
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
pwalker on PROD1PC71 with RULES
and pyraclostrobin 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 pyraclostrobin 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 database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
FQPA safety factor. 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 UFs and/or special FQPA
safety factors, as appropriate.
2. Prenatal and postnatal sensitivity.
The prenatal and postnatal toxicology
database for pyraclostrobin includes the
rat and rabbit developmental toxicity
studies and the 2–generation
reproduction toxicity study in rats.
There was no evidence of increased
quantitative or qualitative susceptibility
of in utero rats or offspring following
exposure to pyraclostrobin in the rat
developmental and reproduction
studies. In the rabbit developmental
study, there was evidence of increased
qualitative susceptibility of in utero
rabbits following exposure to
pyraclostrobin (increases in resorptions/
litter and post-implantation losses).
However, the concern is low for the
qualitative susceptibility in the rabbit
developmental study because: The
developmental effects were seen in the
presence of maternal toxicity; there are
clear NOAELs for maternal and
developmental toxicities; and this
endpoint is used in the acute dietary
(reference dose) exposure assessment for
females, 13 years and older, as well as
for short- and intermediate-term dermal
risk assessments.
3. Conclusion. EPA has determined
that reliable data show that it would be
safe for infants and children to reduce
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
the FQPA safety factor to 1X. This
determination was exhaustively
discussed in a prior order concerning
pyraclostrobin, 72 FR 52108, 52118–
52123 (September 12, 2007). In
summary, the safety factor decision is
based on the following findings:
i. The toxicity database for
pyraclostrobin is complete.
ii. There is no indication that
pyraclostrobin is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. There is no evidence that
pyraclostrobin results in increased
susceptibility in in utero rats in the
prenatal developmental study or in
young rats in the 2–generation
reproduction study. Although there is
qualitative evidence of increased
susceptibility in the prenatal
developmental study in rabbits, the
Agency did not identify any residual
uncertainties after establishing toxicity
endpoints and traditional UFs to be
used in the risk assessment of
pyraclostrobin. The degree of concern
for prenatal toxicity is low.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100 PCT and
tolerance-level residues or anticipated
residues derived from reliable field trial
data. Conservative ground and surface
water modeling estimates were used.
Similarly, conservative assumptions
were used to assess post-application
dermal exposure of children as well as
incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by pyraclostrobin.
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 UFs. 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 UFs is
not exceeded.
1. Acute risk. Using the exposure
assumptions discussed in this unit for
acute exposure, EPA performed two
different acute risk assessments – one
focusing on females 13 to 49 years old
and designed to protect against prenatal
effects and the other focusing on acute
PO 00000
Frm 00043
Fmt 4700
Sfmt 4700
15429
effects relevant to all other population
groups. The more sensitive acute
endpoint was seen as to prenatal effects
rather than other acute effects. For
females 13 to 49 years old, the acute
dietary exposure from food and water
will occupy 80% of the aPAD
addressing prenatal effects. As to acute
effects other than prenatal effects, the
acute dietary exposure from food and
water to pyraclostrobin will occupy
2.4% of the aPAD for children 1 to 2
years old, the population subgroup with
the highest estimated acute dietary
exposure to pyraclostrobin.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that exposure to pyraclostrobin from
food and water will utilize 48% of the
cPAD for children 1 to 2 years old, the
population subgroup with the highest
estimated exposure and risk. Based on
the use pattern, chronic residential
exposure to residues of pyraclostrobin is
not expected.
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).
Pyraclostrobin is currently registered
for uses 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 pyraclostrobin.
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 of
200 for adults and 100 for children, 1 to
2 years old. The aggregate MOE for
adults is based on the residential turf
scenario and includes combined food,
drinking water and post-application
dermal exposures. The aggregate MOE
for children includes food, drinking
water, post-application dermal and
incidental oral exposures from entering
turf areas previously treated with
pyraclostrobin.
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).
Pyraclostrobin is currently registered
for uses 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 pyraclostrobin. Since the
endpoints and points of departure
(NOAELs) are identical for short- and
intermediate-term exposures, the
E:\FR\FM\24MRR1.SGM
24MRR1
15430
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
aggregate MOEs for intermediate-term
exposure are the same as those for shortterm exposure (200 for adults and 100
for children, 1 to 2 years old).
5. Aggregate cancer risk for U.S.
population. EPA has classified
pyraclostrobin into the category ‘‘Not
Likely to be Carcinogenic to Humans.’’
Pyraclostrobin is not expected to pose a
cancer risk.
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, or to infants and children
from aggregate exposure to
pyraclostrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(a liquid chromatography/mass
spectrometry (LC/MS/MS) method
(BASF Method D9808), and a high
performance liquid chromatography
using untraviolet detection (HPLC/UV)
method (BASF Method D9904)) is
available to enforce the tolerance
expression. The methods 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 maximum residue limits
(MRLs) for residues of pyraclostrobin,
per se, at 0.5 ppm in or on oats and
barley and at 0.05 ppm in or on papaya.
The U.S. tolerance levels on these
commodities are higher than the
corresponding CODEX MRLs because
the U.S. tolerances, unlike the Codex
MRLs, include both pyraclostrobin and
its desmethoxy metabolite.

C. Response to Comments
EPA received comments from a
private citizen in response to the notice
of filing of several pesticide petitions
(including PP 6F7105; docket ID
number EPA–HQ–OPP–2007–0214)
which was published in the Federal
Register on May 9, 2007 (72 FR 26372–
26375) (FRL–8121–5). Although none of
the comments specifically addressed
pyraclostrobin, the commenter
expressed concerns generally about the
testing of pesticides, their toxicity
(including potential carcinogenicity),
residues in food and potential effects on
bees. Comments received contained no
scientific data or other substantive
evidence to rebut the Agency’s finding
that there is a reasonable certainty that
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
no harm will result from aggregate
exposure to pyraclostrobin from the
establishment of these tolerances. The
Agency has received these same or
similar comments from this commenter
on numerous previous occasions. Refer
to the Federal Register of June 30, 2005
(70 FR 37686) (FRL–7718–3), Janaury 7,
2005 (70 FR 1354) (FRL–7691–4), and
October 29, 2004 (69 FR 63096–63098)
(FRL–7681–9) for the Agency’s previous
responses to these objections. In
response to the commenter’s question
about potential effects on bees, EPA
would note that the environmental
effects of a pesticide are considered in
the registration process for pesticides
under the Federal Insecticide,
Fungicide, and Rodenticide Act
(FIFRA), 7 U.S.C. 136 et seq.
D. Changes to Proposed Tolerances
Based upon review of the data
supporting the petitions, EPA has
modified the proposed tolerances as
follows: (1) Revised the tolerance levels
for oat, grain from 1.0 ppm to 1.2 ppm;
oat, hay from 17 ppm to 18 ppm; and
oat, straw from 17 ppm to 15 ppm; (2)
decreased the tolerances for avocado,
canistel, mango, papaya, sapodilla,
sapote (black and mamey) and star
apple from 0.7 ppm to 0.6 ppm; and (3)
revised the barley, grain tolerance from
1.3 ppm to 1.4 ppm and determined that
the existing tolerance of 6.0 ppm for
barley, straw is adequate and should not
be raised to 9.0 ppm, as proposed by IR–
4. EPA made these changes based on
analyses of the residue field trial data
using the Agency’s Tolerance
Spreadsheet in accordance with the
Agency’s Guidance for Setting Pesticide
Tolerances Based on Field Trial Data.
V. Conclusion
Therefore, tolerances are established
for combined residues of pyraclostrobin,
carbamic acid, [2-[[[1-(4-chlorophenyl)1H-pyrazol-3yl]oxy]methyl]phenyl]methoxy-, methyl
ester and its desmethoxy metabolite;
methyl-N-[[[1-(4-chlorophenyl)-1Hpyrazol-3yl]oxy]methyl]phenylcarbamate, in or
on avocado at 0.6 ppm; barley, grain at
1.4 ppm; canistel at 0.6 ppm; mango at
0.6 ppm; oat, grain at 1.2 ppm; oat, hay
at 18 ppm; oat, straw at 15 ppm; papaya
at 0.6 ppm; sapodilla at 0.6 ppm; sapote,
black at 0.6 ppm; sapote, mamey at 0.6
ppm; and star apple at 0.6 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes a tolerance
under section 408(d) of FFDCA in
response to petitions submitted to the
Agency. The Office of Management and
PO 00000
Frm 00044
Fmt 4700
Sfmt 4700
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, 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 tolerances in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of 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)
(Public Law 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

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 April 4, 2007 (72 FR 16352) (FRL-8119-
2); May 9, 2007 (72 FR 26372) (FRL-8121-5); and October 24, 2007 (72 FR
60369) (FRL-8150-8), 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 6E7165, PP 6F7105 and PP 7E7245) by Interregional
Research Project Number 4 (IR-4), 500 College Road East, Suite 201W,
Princeton, NJ 08540 and BASF Corporation, P.O. Box 13528, Research
Triangle Park, NC 27709. The petitions requested that 40 CFR 180.582 be
amended by establishing tolerances for combined residues of the
fungicide pyraclostrobin, carbamic acid, [2-[[[1-(4-chlorophenyl)-1H-
pyrazol-3-yl]oxy]methyl]phenyl]methoxy-, methyl ester; and its
desmethoxy metabolite; methyl-N-[[[1-(4-chlorophenyl)-1H-pyrazol-3-
yl]oxy]methyl]phenylcarbamate, in or on herbs, fresh at 30.0 parts per
million (ppm); avocado at 0.7 ppm; mango at 0.7 ppm; papaya at 0.7 ppm;
sapote, black at 0.7 ppm; sapote, mamey at 0.7 ppm; canistel at 0.7
ppm; sapodilla at 0.7 ppm; and star apple at 0.7 ppm
(PP6E7165); in or on oat, grain at 1.0 ppm; oat, hay at 17.0
ppm; oat, straw at 17.0 ppm; and oilseed, group at 0.4 ppm
(PP6F7105); and in or on barley, grain at 1.3 ppm; and barley,
straw at 9.0 ppm (PP7E7245). The notices referenced summaries
of the petitions prepared by BASF Corporation, the registrant, which
are available to the public in docket ID numbers EPA-HQ-OPP-2007-0117
(PP 6E7165); EPA-HQ-OPP-2007-0214 (PP 6F7105); and EPA-HQ-OPP-2007-0906
(PP 7E7245); available at https://www.regulations.gov. There were no
comments received in response to the April 4, 2007 or October 24, 2007
notices of filing; comments were received from a private citizen in
response to the May 9, 2007 notice of filing of pesticide petition
6F7105. EPA's response to these comments is discussed in Unit IV.C.
IR-4 has withdrawn its request for a tolerance for combined
residues of pyraclostrobin and its desmethoxy metabolite in or on fresh
herbs; and EPA is deferring to a later date the decision regarding the
proposed tolerances in or on oilseed commodities. Based upon review of
the data supporting the
[[Page 15427]]
petitions, EPA has revised the tolerance levels for the remaining
commodities. The reason for these changes is explained in Unit IV.D.
III. Aggregate Risk Assessment and Determination of Safety
Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a
tolerance (the legal limit for a pesticide chemical residue in or on a
food) only if EPA determines that the tolerance is ``safe.'' Section
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a
reasonable certainty that no harm will result from aggregate exposure
to the pesticide chemical residue, including all anticipated dietary
exposures and all other exposures for which there is reliable
information.'' This includes exposure through drinking water and in
residential settings, but does not include occupational exposure.
Section 408(b)(2)(C) of FFDCA requires EPA to give special
consideration to exposure of infants and children to the pesticide
chemical residue in establishing a tolerance and to ``ensure that there
is a reasonable certainty that no harm will result to infants and
children from aggregate exposure to the pesticide chemical residue. . .
.'' These provisions were added to FFDCA by the Food Quality Protection
Act (FQPA) of 1996.
Consistent with section 408(b)(2)(D) of FFDCA, and the factors
specified in 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 for the petitioned-for
tolerances for combined residues of pyraclostrobin and its desmethoxy
metabolite on avocado at 0.6 ppm; barley, grain at 1.4 ppm; canistel at
0.6 ppm; mango at 0.6 ppm; oat, grain at 1.2 ppm; oat, hay at 18 ppm;
oat, straw at 15 ppm; papaya at 0.6 ppm; sapodilla at 0.6 ppm; sapote,
black at 0.6 ppm; sapote, mamey at 0.6 ppm; and star apple at 0.6 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.
Pyraclostrobin has low to moderate acute toxicity. In repeated dose
oral toxicity studies, the main target organs for pyraclostrobin are
the upper gastrointestinal tract (mainly the duodenum and stomach), the
spleen/hematopoiesis, the immune system, and the liver. There was no
evidence of increased quantitative or qualitative susceptibility of in
utero rats or offspring following exposure to pyraclostrobin in the rat
developmental or reproduction toxicity studies. There was evidence of
increased qualitative susceptibility of in utero rabbits following
exposure to pyraclostrobin in the rabbit developmental study. Increases
in resorptions/litter and post-implantation losses occurred at doses
that resulted in less severe maternal toxicity (decreases in body
weight gain and food consumption). In both the acute and subchronic
neurotoxicity studies, there were no indications of treatment-related
neurotoxicity.
EPA has evaluated the carcinogenic potential of pyraclostrobin and
concluded that, in accordance with the EPA's Final Guidelines for
Carcinogen Risk Assessment (March 2005), pyraclostrobin should be
classified into the category ``Not Likely to be Carcinogenic to
Humans.'' This determination is based on no treatment-related increase
in tumors in either sex of rats and mice, which were tested at doses
that were adequate to assess carcinogenicity, and the lack of evidence
of mutagenicity.
Specific information on the studies received and the nature of the
adverse effects caused by pyraclostrobin as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://
www.regulations.gov in the document Pyraclostrobin: Human Health Risk
Assessment for Proposed Uses on Oats, Oilseed Group (Canola and Flax),
Plus Seed Treatment on Oats, Canola, and Flax; Tropical Fruits
(Avocado, Black Sapote, Canistel, Mamey Sapote, Mango; Papaya,
Sapodilla, and Star Apple); Increased Tolerance on Barley; Adding
Aerial Application to Turf and Ornamentals; and Adding In-Furrow
Applications to Corn, Soybean, and Sugar Beets. The referenced document
is available in the docket established by this action, which is
described under ADDRESSES, and is identified as EPA-HQ-OPP-2007-0906-
0003 in that docket.
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 (UFs)
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 UFs. 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
UFs 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/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for pyraclostrobin used
for human risk assessment can be found at https://www.regulations.gov in
the document Pyraclostrobin: Human Health Risk Assessment for Proposed
Uses on Oats, Oilseed Group (Canola and Flax), Plus Seed Treatment on
Oats, Canola, and Flax; Tropical Fruits (Avocado, Black Sapote,
Canistel, Mamey Sapote, Mango; Papaya, Sapodilla, and Star Apple);
Increased Tolerance on Barley; Adding Aerial Application to Turf and
Ornamentals; and Adding In-Furrow Applications to Corn, Soybean, and
Sugar Beets at page 21 to 23 in docket ID number EPA-HQ-OPP-2007-0003.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to pyraclostrobin, EPA considered exposure under the
petitioned-for tolerances as well as all existing pyraclostrobin
tolerances in 40 CFR 180.582. EPA assessed dietary
[[Page 15428]]
exposures from pyraclostrobin 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. EPA identified such an
effect for the general population (decreased body weight gain seen
after a single oral dose in the rat acute neurotoxicity study) and for
females 13 to 49 years old (increased resorptions/litter and increased
total resorptions seen in the rabbit developmental toxicity study that
are presumed to occur after a single exposure). The aPAD for the
general population has been established at 3.0 milligrams/kilogram/day
(mg/kg/day); whereas, the aPAD for females 13 to 49 years old is
significantly lower (0.05 mg/kg/day), due to the more sensitive
endpoint on which it is based.
In estimating acute dietary exposure, EPA used food consumption
information from the U.S. Department of Agriculture (USDA) 1994-1996
and 1998 Nationwide Continuing Surveys of Food Intake by Individuals
(CSFII). As to residue levels in food, EPA assumed that residues are
present at tolerance levels or for some commodities (amaranth, leafy;
arugula; chrysanthemum; cress, garden; cress, upland; dandelion,
leaves; fennel; parsley, leaves; radicchio; rhubarb; spinach; swiss
chard; beans, dry; celery; lettuce, head; lettuce, leaf; and pea, dry)
at the highest residue level found in residue field trials. One hundred
percent crop treated (PCT) was assumed for all commodities in the
assessment. Default processing factors were applied to all commodities
except those for which experimentally-derived processing factors were
available: apple juice, grape juice, citrus juices, cottonseed oil,
tomato paste, tomato puree, wheat flour, and wheat germ.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 CSFII. As to residue levels in food, EPA assumed that residues
are present at tolerance levels in all crops except apple, broccoli,
celery, collard, grape, lettuce, citrus, pepper, mustard green and
tomato. EPA relied on anticipated residues (average residues from field
trials) for these crops. One hundred PCT was assumed for all
commodities in the assessment. Default processing factors were applied
to all commodities except those for which experimentally-derived
processing factors were available: apple juice, grape juice, citrus
juices, tomato paste, tomato puree, wheat flour, and wheat germ.
iii. Cancer. Based on the results of carcinogenicity studies in
rats and mice, EPA has concluded that pyraclostrobin is ``not likely to
be carcinogenic to humans.'' Consequently, a quantitative cancer
exposure and risk assessment is not appropriate for pyraclostrobin.
iv. Anticipated residue 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) of FFDCA,
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.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring data to complete a comprehensive dietary exposure
analysis and risk assessment for pyraclostrobin 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 pyraclostrobin. Further information regarding
EPA drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on the 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
pyraclostrobin for acute exposures are estimated to be 35.6 parts per
billion (ppb) for surface water and 0.02 ppb for ground water. The EECs
for chronic exposures are estimated to be 2.3 ppb for surface water and
0.02 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 35.6 ppb was used to
assess the contribution to drinking water. For chronic dietary risk
assessment, the water concentration value of 2.3 ppb was used to assess
the contribution to drinking water.
3. From non-dietary exposure. The term ``residential exposure'' is
used in this document to refer to non-occupational, non-dietary
exposure (e.g., for lawn and garden pest control, indoor pest control,
termiticides, and flea and tick control on pets).
Pyraclostrobin is currently registered for the following
residential non-dietary sites: Residential and recreational turfgrass.
EPA assessed residential exposure using the following assumptions:
Residential and recreational turf applications are applied by
professional pest control operators (PCOs) only, and, therefore,
residential handler exposures do not occur. There is, however, a
potential for short- and intermediate-term postapplication exposure of
adults and children entering lawn and recreation areas previously
treated with pyraclostrobin. Exposures from treated recreational sites
are expected to be similar to, or in many cases lower than, those from
treated residential turf sites; therefore, a separate exposure
assessment for recreational turf sites was not conducted. EPA assessed
exposures from the following residential turf postapplication
scenarios:
i. Adult and toddler postapplication dermal exposure from contact
with treated lawns,
ii. Toddlers' incidental ingestion of pesticide residues on lawns
from hand-to-mouth transfer,
iii. Toddlers' object-to-mouth transfer from mouthing of pesticide-
treated turfgrass, and
iv. Toddlers' incidental ingestion of soil from pesticide-treated
residential areas. The postapplication risk assessment was conducted in
accordance with the Residential Standard Operating Procedures (SOPs)
and recommended approaches of the Health Effects Division's (HED's)
Science Advisory Council for Exposure (ExpoSAC).
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to pyraclostrobin and any
other substances
[[Page 15429]]
and pyraclostrobin 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 pyraclostrobin 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 database on toxicity and
exposure unless EPA determines based on reliable data that a different
margin of safety will be safe for infants and children. This additional
margin of safety is commonly referred to as the FQPA safety factor. 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 UFs and/or special
FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. The prenatal and postnatal
toxicology database for pyraclostrobin includes the rat and rabbit
developmental toxicity studies and the 2-generation reproduction
toxicity study in rats. There was no evidence of increased quantitative
or qualitative susceptibility of in utero rats or offspring following
exposure to pyraclostrobin in the rat developmental and reproduction
studies. In the rabbit developmental study, there was evidence of
increased qualitative susceptibility of in utero rabbits following
exposure to pyraclostrobin (increases in resorptions/litter and post-
implantation losses). However, the concern is low for the qualitative
susceptibility in the rabbit developmental study because: The
developmental effects were seen in the presence of maternal toxicity;
there are clear NOAELs for maternal and developmental toxicities; and
this endpoint is used in the acute dietary (reference dose) exposure
assessment for females, 13 years and older, as well as for short- and
intermediate-term dermal risk assessments.
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. This determination was exhaustively discussed in a prior order
concerning pyraclostrobin, 72 FR 52108, 52118-52123 (September 12,
2007). In summary, the safety factor decision is based on the following
findings:
i. The toxicity database for pyraclostrobin is complete.
ii. There is no indication that pyraclostrobin is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. There is no evidence that pyraclostrobin results in increased
susceptibility in in utero rats in the prenatal developmental study or
in young rats in the 2-generation reproduction study. Although there is
qualitative evidence of increased susceptibility in the prenatal
developmental study in rabbits, the Agency did not identify any
residual uncertainties after establishing toxicity endpoints and
traditional UFs to be used in the risk assessment of pyraclostrobin.
The degree of concern for prenatal toxicity is low.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 PCT and tolerance-level residues or anticipated residues derived
from reliable field trial data. Conservative ground and surface water
modeling estimates were used. Similarly, conservative assumptions were
used to assess post-application dermal exposure of children as well as
incidental oral exposure of toddlers. These assessments will not
underestimate the exposure and risks posed by pyraclostrobin.
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 UFs. 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 UFs is
not exceeded.
1. Acute risk. Using the exposure assumptions discussed in this
unit for acute exposure, EPA performed two different acute risk
assessments - one focusing on females 13 to 49 years old and designed
to protect against prenatal effects and the other focusing on acute
effects relevant to all other population groups. The more sensitive
acute endpoint was seen as to prenatal effects rather than other acute
effects. For females 13 to 49 years old, the acute dietary exposure
from food and water will occupy 80% of the aPAD addressing prenatal
effects. As to acute effects other than prenatal effects, the acute
dietary exposure from food and water to pyraclostrobin will occupy 2.4%
of the aPAD for children 1 to 2 years old, the population subgroup with
the highest estimated acute dietary exposure to pyraclostrobin.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
pyraclostrobin from food and water will utilize 48% of the cPAD for
children 1 to 2 years old, the population subgroup with the highest
estimated exposure and risk. Based on the use pattern, chronic
residential exposure to residues of pyraclostrobin is not expected.
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).
Pyraclostrobin is currently registered for uses 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 pyraclostrobin.
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 of 200 for adults and 100
for children, 1 to 2 years old. The aggregate MOE for adults is based
on the residential turf scenario and includes combined food, drinking
water and post-application dermal exposures. The aggregate MOE for
children includes food, drinking water, post-application dermal and
incidental oral exposures from entering turf areas previously treated
with pyraclostrobin.
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).
Pyraclostrobin is currently registered for uses 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 pyraclostrobin. Since the endpoints and
points of departure (NOAELs) are identical for short- and intermediate-
term exposures, the
[[Page 15430]]
aggregate MOEs for intermediate-term exposure are the same as those for
short-term exposure (200 for adults and 100 for children, 1 to 2 years
old).
5. Aggregate cancer risk for U.S. population. EPA has classified
pyraclostrobin into the category ``Not Likely to be Carcinogenic to
Humans.'' Pyraclostrobin is not expected to pose a cancer risk.
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, or to infants and children from aggregate
exposure to pyraclostrobin residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (a liquid chromatography/mass
spectrometry (LC/MS/MS) method (BASF Method D9808), and a high
performance liquid chromatography using untraviolet detection (HPLC/UV)
method (BASF Method D9904)) is available to enforce the tolerance
expression. The methods 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 maximum residue
limits (MRLs) for residues of pyraclostrobin, per se, at 0.5 ppm in or
on oats and barley and at 0.05 ppm in or on papaya. The U.S. tolerance
levels on these commodities are higher than the corresponding CODEX
MRLs because the U.S. tolerances, unlike the Codex MRLs, include both
pyraclostrobin and its desmethoxy metabolite.
C. Response to Comments
EPA received comments from a private citizen in response to the
notice of filing of several pesticide petitions (including PP 6F7105;
docket ID number EPA-HQ-OPP-2007-0214) which was published in the
Federal Register on May 9, 2007 (72 FR 26372-26375) (FRL-8121-5).
Although none of the comments specifically addressed pyraclostrobin,
the commenter expressed concerns generally about the testing of
pesticides, their toxicity (including potential carcinogenicity),
residues in food and potential effects on bees. Comments received
contained no scientific data or other substantive evidence to rebut the
Agency's finding that there is a reasonable certainty that no harm will
result from aggregate exposure to pyraclostrobin from the establishment
of these tolerances. The Agency has received these same or similar
comments from this commenter on numerous previous occasions. Refer to
the Federal Register of June 30, 2005 (70 FR 37686) (FRL-7718-3),
Janaury 7, 2005 (70 FR 1354) (FRL-7691-4), and October 29, 2004 (69 FR
63096-63098) (FRL-7681-9) for the Agency's previous responses to these
objections. In response to the commenter's question about potential
effects on bees, EPA would note that the environmental effects of a
pesticide are considered in the registration process for pesticides
under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA),
7 U.S.C. 136 et seq.
D. Changes to Proposed Tolerances
Based upon review of the data supporting the petitions, EPA has
modified the proposed tolerances as follows: (1) Revised the tolerance
levels for oat, grain from 1.0 ppm to 1.2 ppm; oat, hay from 17 ppm to
18 ppm; and oat, straw from 17 ppm to 15 ppm; (2) decreased the
tolerances for avocado, canistel, mango, papaya, sapodilla, sapote
(black and mamey) and star apple from 0.7 ppm to 0.6 ppm; and (3)
revised the barley, grain tolerance from 1.3 ppm to 1.4 ppm and
determined that the existing tolerance of 6.0 ppm for barley, straw is
adequate and should not be raised to 9.0 ppm, as proposed by IR-4. EPA
made these changes based on analyses of the residue field trial data
using the Agency's Tolerance Spreadsheet in accordance with the
Agency's Guidance for Setting Pesticide Tolerances Based on Field Trial
Data.
V. Conclusion
Therefore, tolerances are established for combined residues of
pyraclostrobin, carbamic acid, [2-[[[1-(4-chlorophenyl)-1H-pyrazol-3-
yl]oxy]methyl]phenyl]methoxy-, methyl ester and its desmethoxy
metabolite; methyl-N-[[[1-(4-chlorophenyl)-1H-pyrazol-3-
yl]oxy]methyl]phenylcarbamate, in or on avocado at 0.6 ppm; barley,
grain at 1.4 ppm; canistel at 0.6 ppm; mango at 0.6 ppm; oat, grain at
1.2 ppm; oat, hay at 18 ppm; oat, straw at 15 ppm; papaya at 0.6 ppm;
sapodilla at 0.6 ppm; sapote, black at 0.6 ppm; sapote, mamey at 0.6
ppm; and star apple at 0.6 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes a tolerance under section 408(d) of
FFDCA in response to petitions 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, 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 tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of 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) (Public Law 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
[[Page 15431]]
Transfer and Advancement Act of 1995 (NTTAA), Public Law 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).
