II. Petition for Tolerance
In the Federal Register of May 16,
2008 (73 FR 28461) (FRL–8361–6), EPA
issued a notice pursuant to section
408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide petition (PP 8E7314) by
Interregional Research Project (IR-4),
500 College Rd. East, Suite 201 W.,
Princeton, NJ 08540. The petition
requested that 40 CFR 180.493 be
amended by establishing tolerances for
residues of the fungicide
dimethomorph, (E,Z) 4-[3-(4chlorophenyl)-3-(3,4-dimethoxyphenyl)1-oxo-2-propenyl]morpholine, in or on
beans, lima at 0.60 parts per million
(ppm); ginseng at 0.85 ppm; grape at 3.5
ppm; grape, raisin at 6.0 ppm; and
turnip, greens at 20.0 ppm. In the
Federal Register of October 8, 2008 (73
FR 58962) (FRL–8383–7), EPA issued a
notice pursuant to section 408(d)(3) of
FFDCA, 21 U.S.C. 346a(d)(3),
announcing the filing of an amendment
to the pesticide petition (PP 8E7314) by
IR-4, which requested that 40 CFR
180.493 be amended for residues of the
fungicide dimethomorph by increasing
the tolerance in or on potato, wet peel
from 0.15 ppm to 0.20 ppm, and reestablishing the tolerance in or on
potato at 0.05 ppm. These notices
referenced a summary of the petition
prepared on behalf of IR-4 by BASF
Corporation, the registrant, which is
available to the public in the docket,
https://www.regulations.gov. There were
no comments received in response to
the notices of filing.
Based upon review of the data
supporting the petition, EPA has
determined that the proposed tolerance
level for ginseng should be increased.
EPA has additionally determined that
the proposed tolerances for beans, lima
and grape should be established as
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
regional tolerances, and that the import
tolerance for grape, raisin should
remain. The reasons for these changes
are 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. . . .’’
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 residues of dimethomorph
on beans, lima at 0.60 ppm; ginseng at
0.90 ppm; grape at 3.5 ppm; grape,
raisin at 6.0 ppm; potato at 0.05 ppm;
potato, wet peel at 0.20 ppm; and
turnip, greens at 20 ppm. EPA’s
assessment of exposures and risks
associated with establishing tolerances
follows.
A. Toxicological Profile
EPA has evaluated the available
toxicity data and considered its validity,
completeness, and reliability as well as
the relationship of the results of the
studies to human risk. EPA has also
considered available information
concerning the variability of the
sensitivities of major identifiable
subgroups of consumers, including
infants and children.
The existing dimethomorph data
indicate that it possesses relatively low
toxicity. No appropriate toxicological
endpoints attributable to a single
exposure were identified in oral studies.
Consequently, it was determined that
there was no basis for selecting a dose
E:\FR\FM\04MRR1.SGM
04MRR1
Federal Register / Vol. 74, No. 41 / Wednesday, March 4, 2009 / Rules and Regulations
and endpoint for an acute reference
dose (aRfD).
In the dimethomorph rat chronic
dietary feeding study, there were
significant body weight decrements, and
liver effects in female rats. Available
data for dimethomorph do not show
potential for immunotoxic nor
neurotoxic effects. Neither the
subchronic nor chronic toxicity studies
in rats or dogs, nor the developmental
toxicity studies indicated that the
nervous system was affected by
treatment with dimethomorph.
Based on the toxicity profile for
dimethomorph, a developmental
neurotoxicity (DNT) study in rats is not
required. In a carcinogenicity study in
rat, there was no evidence of increased
incidence of any neopolasms at any
doses. In a carcinogenicity study in
mice, there was no dose-related
decrease in survival, or in any
parameter examined on necropsy. At the
maximum dose required by the test
guidelines for a dietary oncogenicity
study, there was no evidence of
carcinogenicity. Therefore, the EPA
classified dimethomorph as ‘‘not likely
to be carcinogenic to humans.’’
The toxicology data on dimethomorph
provides no indication of enhanced
sensitivity of infants and children,
based on the results from developmental
studies conducted with rats and rabbits,
as well as a 2-generation reproduction
study conducted with rats. There were
no toxic effects observed in either the
rat developmental toxicity, or the rat 2generation reproductive toxicity studies,
that were observed at lower doses than
those which produced toxic effects in
the parents. No developmental toxicity
was demonstrated in the rabbit
developmental toxicity study.
Specific information on the studies
received and the nature of the adverse
effects caused by dimethomorph as well
as the no-observed-adverse-effect-level
and the lowest-observed-adverse-effectlevel from the toxicity studies can be
found at https://www.regulations.gov in
document ‘‘Dimethomorph. Human
Health Risk Assessment for the
Proposed Food/Feed Use of the
Fungicide (Associated with Section 3
Registration) on Succulent Lima Beans,
Ginseng, Grapes and Turnip Tops’’ at
pages 46–49 in docket ID number EPA–
HQ–OPP–2008–0258.
B. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, a toxicological point of departure
(POD) is identified as the basis for
derivation of reference values for risk
assessment. The POD may be defined as
the highest dose at which no adverse
VerDate Nov<24>2008
15:05 Mar 03, 2009
Jkt 217001
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) or a Benchmark Dose
(BMD) approach is sometimes used for
risk assessment. Uncertainty/safety
factors (UFs) are used in conjunction
with the POD 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 dietary risks by comparing
aggregate food and water 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 POD by all applicable UFs.
Aggregate short-term, intermediate-term,
and chronic-term risks are evaluated by
comparing food, water, and residential
exposure to the POD to ensure that the
margin of exposure (MOE) called for by
the product of all applicable UFs is not
exceeded. This latter value is referred to
as the Level of Concern (LOC).
For non-threshold risks, the Agency
assumes that any amount of exposure
will lead to some degree of risk. Thus,
the Agency estimates risk in terms of the
probability of an occurrence of the
adverse effect greater than that expected
in a lifetime. For more information on
the general principles EPA uses in risk
characterization and a complete
description of the risk assessment
process, see https://www.epa.gov/
pesticides/factsheets/riskassess.htm.
A summary of the toxicological
endpoints for dimethomorph used for
human risk assessment can be found at
https://www.regulations.gov in document
‘‘Dimethomorph. Human Health Risk
Assessment for the Proposed Food/Feed
Use of the Fungicide (Associated with
Section 3 Registration) on Succulent
Lima Beans, Ginseng, Grapes and
Turnip Tops’’ at pages 17–18 in docket
ID number EPA–HQ–OPP–2008–0258.
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to dimethomorph, EPA
considered exposure under the
petitioned-for tolerances as well as all
existing dimethomorph tolerances in (40
CFR 180.493). EPA assessed dietary
exposures from dimethomorph in food
as follows:
i. Acute exposure. Quantitative acute
dietary exposure and risk assessments
are performed for a food-use pesticide,
PO 00000
Frm 00011
Fmt 4700
Sfmt 4700
9353
if a toxicological study has indicated the
possibility of an effect of concern
occurring as a result of a 1 day or single
exposure.
No such effects were identified in the
toxicological studies for dimethomorph;
therefore, a quantitative acute dietary
exposure assessment is unnecessary.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
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 used
tolerance-level residues, the Dietary
Exposure Evaluation Model (DEEM)
default processing factors, and assumed
100 percent crop treated (PCT) for all
proposed commodities.
iii. Cancer. Based on the results of the
carcinogenicity studies in rats and mice,
dimethomorph has been classified as
‘‘not likely to be carcinogenic to
humans;’’ therefore, a quantitative
exposure assessment to evaluate cancer
risk is unnecessary.
iv. Anticipated residue and PCT
information. EPA did not use
anticipated residue and/or PCT
information in the dietary assessment
for dimethomorph. Tolerance level
residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for dimethomorph in drinking water.
These simulation models take into
account data on the physical, chemical,
and fate/transport characteristics of
dimethomorph. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at https://www.epa.gov/
oppefed1/models/water/index.htm.
The First Index Reservoir Screening
Tool (FIRST) Tier 1 model was used to
estimate concentrations for
dimethomorph in surface water. The
Tier 1 Screening Concentration in
Ground Water (SCI-GROW) model was
utilized to predict concentrations in
ground water. The Tier 1 Generic
Estimated Environmental Concentration
(GENEEC) model, from a previous
drinking water assessment, calculated
another estimated drinking water
concentration (EDWC) for
dimethomorph in surface water. The
EDWCs of dimethomorph for acute
exposures are estimated to be 81.1 parts
per billion (ppb) for surface water and
0.264 ppb for ground water. For chronic
exposures, the non-cancer assessments
are estimated to be 24.7 ppb for surface
water, 28.5 ppb for a previously
E:\FR\FM\04MRR1.SGM
04MRR1
9354
Federal Register / Vol. 74, No. 41 / Wednesday, March 4, 2009 / Rules and Regulations
determined surface water assessment,
and 0.264 ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
chronic dietary risk assessment, the
most conservative water concentration
of value 28.5 ppb, from GENEEC
modeling, 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).
Dimethomorph is not registered for any
specific use patterns that would result
in residential exposure.
4. Cumulative effects from substances
with a common mechanism of toxicity.
Section 408(b)(2)(D)(v) of FFDCA
requires that, when considering whether
to establish, modify, or revoke a
tolerance, the Agency consider
‘‘available information’’ concerning the
cumulative effects of a particular
pesticide’s residues and ‘‘other
substances that have a common
mechanism of toxicity.’’
EPA has not found dimethomorph to
share a common mechanism of toxicity
with any other substances, and
dimethomorph does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that dimethomorph does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s website at https://
www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and
Children
1. In general. Section 408(b)(2)(c) of
FFDCA provides that EPA shall apply
an additional tenfold (10X) margin of
safety for infants and children in the
case of threshold effects to account for
prenatal and postnatal toxicity and the
completeness of the database on toxicity
and exposure unless EPA determines
based on reliable data that a different
margin of safety will be safe for infants
and children. This additional margin of
safety is commonly referred to as the
Food Quality Protection Act (FQPA)
safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional SF when reliable data
available to EPA support the choice of
a different factor.
VerDate Nov<24>2008
15:05 Mar 03, 2009
Jkt 217001
2. Prenatal and postnatal sensitivity.
The toxicology data on dimethomorph
provides no indication of enhanced
sensitivity of infants and children,
based on the results from developmental
studies conducted with rats and rabbits,
as well as a 2–generation reproduction
study conducted with rats. There were
no toxic effects observed in either the
rat developmental toxicity, or the rat 2–
generation reproductive toxicity studies,
that were observed at lower doses than
those which produced toxic effects in
the parents. Further, clear NOAELs were
observed for all effects observed in
fetuses. These NOAELs are well above
the NOAEL used as a point of departure
in assessing the safety of
dimethomorph. No developmental
toxicity was demonstrated in the rabbit
developmental toxicity study.
Additionally, there is no evidence of
neurotoxicity.
3. Conclusion. EPA has determined
that reliable data show the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1X. That decision is
based on the following findings:
i. The toxicity database for
dimethomorph is complete except for
the immunotoxicity, acute
neurotoxicity, and subchronic
neurotoxicity studies. Recent changes to
40 CFR part 158 make acute and
subchronic neurotoxicity testing
(OPPTS Guideline 870.6200), and
immunotoxicity testing (OPPTS
Guideline 870.7800) required for
pesticide registration. The available data
for dimethomorph do not show
potential for immunotoxic or neurotoxic
effects. Therefore, EPA does not believe
that conducting OPPTS Guideline
870.6200 neurotoxicity and OPPTS
Guideline 870.7800 immunotoxicity
studies will result in a NOAEL lower
than the NOAEL of 11 milligram/
kilogram/day (mg/kg/day) already set
for dimethomorph. Consequently, an
additional database uncertainty factor
(UF) does not need to be applied.
ii. There is no indication that
dimethomorph is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
neurotoxicity.
iii. The developmental and
reproductive toxicity data did not
indicate increased quantitative or
qualitative susceptibility of rats or
rabbits to in utero and/or postnatal
exposure to dimethomorph. There are
no residual concerns regarding
developmental effects in the young.
iv. There are no residual uncertainties
identified in the exposure databases.
Dietary food exposure assessments were
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
performed based on 100 PCT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to
dimethomorph in drinking water. These
assessments will not underestimate the
exposure and risks posed by
dimethomorph.
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic pesticide exposures are safe by
comparing aggregate exposure estimates
to the aPAD and cPAD. The aPAD and
cPAD represent the highest safe
exposures, taking into account all
appropriate SFs. EPA calculates the
aPAD and cPAD by dividing the POD by
all applicable UFs. For linear cancer
risks, EPA calculates the probability of
additional cancer cases given the
estimated aggregate exposure. Shortterm, intermediate-term, and chronicterm risks are evaluated by comparing
the estimated aggregate food, water, and
residential exposure to the POD to
ensure that the MOE called for by the
product of all applicable UFs is not
exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account exposure
estimates from acute dietary
consumption of food and drinking
water. No acute dietary endpoint was
identified for any segment of the U.S.
population. Therefore, dimethomorph is
not expected to pose an acute risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to dimethomorph
from food and water will utilize 20% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. There are no residential uses
for dimethomorph to consider.
3. Short-term and intermediate-term
risk. Short-term and intermediate-term
aggregate exposure takes into account
short-term and intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level).
Dimethomorph is not registered for
any use patterns that would result in
residential exposure. Therefore, the
short-term and intermediate-term
aggregate risk is the sum of the risk from
exposure to dimethomorph through
food and water and will not be greater
than the chronic aggregate risk.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in mice and
rats at doses that were judged to be
adequate to assess the carcinogenic
potential, dimethomorph was classified
E:\FR\FM\04MRR1.SGM
04MRR1
Federal Register / Vol. 74, No. 41 / Wednesday, March 4, 2009 / Rules and Regulations
as ‘‘not likely to be carcinogenic to
humans.’’ Therefore, dimethomorph is
not expected to pose a cancer risk to
humans.
5. Determination of safety. Based on
these risk assessments, EPA concludes
that there is a reasonable certainty that
no harm will result to the general
population, or to infants and children
from aggregate exposure to
dimethomorph residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(High-Performance Liquid
Chromatography using Ultraviolet
detection (HPLC/UV) Method, (FAMS)
002–04) 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
There are no Canadian or Mexican
maximum residue limits (MRLs)
established for residues of
dimethomorph in crops associated with
this review. Codex MRLs have been
finalized in grapes and grape, raisins at
2 and 5 ppm, respectively. However, the
proposed tolerances in grape and grape,
raisin (3.5 and 6.0 ppm, respectively)
cannot be harmonized with the Codex
MRLs on these commodities because
field trial data shows residue levels for
grape that are higher than 2 ppm.
C. Revisions to Petitioned-For
Tolerances
Based upon review of the data
supporting the petition, EPA revised the
proposed tolerance for ginseng, from
0.85 ppm to 0.90 ppm. EPA revised the
proposed tolerance based on analysis 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. EPA also changed
the commodity term from ‘‘bean, lima’’
to ‘‘bean, lima, succulent’’ because field
trial data for dry lima beans was not
submitted. Use on lima beans is
restricted to those varieties intended for
harvest as succulent seed. Use on lima
beans is also restricted to areas east of
the Rocky Mountains, and will therefore
be established as a regional tolerance
under paragraph (c) Tolerances with
regional registrations in §180.493. The
proposed tolerance for grape will also be
restricted to a regional tolerance under
§180.493(c), since data were submitted
VerDate Nov<24>2008
15:05 Mar 03, 2009
Jkt 217001
to support use of dimethomorph on
grapes grown east of the Rocky
Mountains. Since grapes processed for
raisin production are only grown west
of the Rock Mountains, the import
tolerance for raisins will remain, and a
tolerance for raisin under § 180.493(c)
will not be established.
V. Conclusion
Therefore, tolerances are established
for residues of dimethomorph (E,Z) 4-[3(4-chlorophenyl)-3-(3,4dimethoxyphenyl)-1-oxo-2propenyl]morpholine, in or on ginseng
at 0.90 ppm and turnip, greens at 20.0
ppm. Tolerances with regional
registrations are established in or on
bean, lima, succulent at 0.6 ppm and
grape at 3.5 ppm. This regulation also
deletes the existing tolerance for use in
or on grape, as the regional tolerance
supersedes it. Finally, it increases the
existing import tolerance level for
potato, wet peel from 0.15 to 0.20 ppm
and re-establishes the tolerance for
potato at 0.05 ppm.
VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
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 final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled Actions Concerning Regulations
That Significantly Affect Energy Supply,
Distribution, or Use (66 FR 28355, May
22, 2001) or Executive Order 13045,
entitled Protection of Children from
Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997).
This final rule does not contain any
information collections subject to OMB
approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special
considerations under Executive Order
12898, entitled Federal Actions to
Address Environmental Justice in
Minority Populations and Low-Income
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under 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.
PO 00000
Frm 00013
Fmt 4700

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 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (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
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).

II. Petition for Tolerance
In the Federal Register of May 16, 2008 (73 FR 28461) (FRL-8361-6),
EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a pesticide petition (PP 8E7314)
by Interregional Research Project (IR-4), 500 College Rd. East, Suite
201 W., Princeton, NJ 08540. The petition requested that 40 CFR 180.493
be amended by establishing tolerances for residues of the fungicide
dimethomorph, (E,Z) 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-
oxo-2-propenyl]morpholine, in or on beans, lima at 0.60 parts per
million (ppm); ginseng at 0.85 ppm; grape at 3.5 ppm; grape, raisin at
6.0 ppm; and turnip, greens at 20.0 ppm. In the Federal Register of
October 8, 2008 (73 FR 58962) (FRL-8383-7), EPA issued a notice
pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3),
announcing the filing of an amendment to the pesticide petition (PP
8E7314) by IR-4, which requested that 40 CFR 180.493 be amended for
residues of the fungicide dimethomorph by increasing the tolerance in
or on potato, wet peel from 0.15 ppm to 0.20 ppm, and re-establishing
the tolerance in or on potato at 0.05 ppm. These notices referenced a
summary of the petition prepared on behalf of IR-4 by BASF Corporation,
the registrant, which is available to the public in the docket, https://www.regulations.gov. There were no comments received in response to the
notices of filing.
Based upon review of the data supporting the petition, EPA has
determined that the proposed tolerance level for ginseng should be
increased. EPA has additionally determined that the proposed tolerances
for beans, lima and grape should be established as regional tolerances,
and that the import tolerance for grape, raisin should remain. The
reasons for these changes are 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. . .
.''
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 residues of dimethomorph on beans, lima at 0.60 ppm;
ginseng at 0.90 ppm; grape at 3.5 ppm; grape, raisin at 6.0 ppm; potato
at 0.05 ppm; potato, wet peel at 0.20 ppm; and turnip, greens at 20
ppm. EPA's assessment of exposures and risks associated with
establishing tolerances follows.
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
children.
The existing dimethomorph data indicate that it possesses
relatively low toxicity. No appropriate toxicological endpoints
attributable to a single exposure were identified in oral studies.
Consequently, it was determined that there was no basis for selecting a
dose
[[Page 9353]]
and endpoint for an acute reference dose (aRfD).
In the dimethomorph rat chronic dietary feeding study, there were
significant body weight decrements, and liver effects in female rats.
Available data for dimethomorph do not show potential for immunotoxic
nor neurotoxic effects. Neither the subchronic nor chronic toxicity
studies in rats or dogs, nor the developmental toxicity studies
indicated that the nervous system was affected by treatment with
dimethomorph.
Based on the toxicity profile for dimethomorph, a developmental
neurotoxicity (DNT) study in rats is not required. In a carcinogenicity
study in rat, there was no evidence of increased incidence of any
neopolasms at any doses. In a carcinogenicity study in mice, there was
no dose-related decrease in survival, or in any parameter examined on
necropsy. At the maximum dose required by the test guidelines for a
dietary oncogenicity study, there was no evidence of carcinogenicity.
Therefore, the EPA classified dimethomorph as ``not likely to be
carcinogenic to humans.''
The toxicology data on dimethomorph provides no indication of
enhanced sensitivity of infants and children, based on the results from
developmental studies conducted with rats and rabbits, as well as a 2-
generation reproduction study conducted with rats. There were no toxic
effects observed in either the rat developmental toxicity, or the rat
2-generation reproductive toxicity studies, that were observed at lower
doses than those which produced toxic effects in the parents. No
developmental toxicity was demonstrated in the rabbit developmental
toxicity study.
Specific information on the studies received and the nature of the
adverse effects caused by dimethomorph as well as the no-observed-
adverse-effect-level and the lowest-observed-adverse-effect-level from
the toxicity studies can be found at https://www.regulations.gov in
document ``Dimethomorph. Human Health Risk Assessment for the Proposed
Food/Feed Use of the Fungicide (Associated with Section 3 Registration)
on Succulent Lima Beans, Ginseng, Grapes and Turnip Tops'' at pages 46-
49 in docket ID number EPA-HQ-OPP-2008-0258.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, a toxicological point of departure (POD) is
identified as the basis for derivation of reference values for risk
assessment. The POD may be defined as 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) or a Benchmark Dose (BMD) approach
is sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the POD 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
dietary risks by comparing aggregate food and water 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 POD by all applicable UFs. Aggregate short-term,
intermediate-term, and chronic-term risks are evaluated by comparing
food, water, and residential exposure to the POD to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded. This latter value is referred to as the Level of
Concern (LOC).
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk. Thus, the Agency estimates
risk in terms of the probability of an occurrence of the adverse effect
greater than that expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for dimethomorph used for
human risk assessment can be found at https://www.regulations.gov in
document ``Dimethomorph. Human Health Risk Assessment for the Proposed
Food/Feed Use of the Fungicide (Associated with Section 3 Registration)
on Succulent Lima Beans, Ginseng, Grapes and Turnip Tops'' at pages 17-
18 in docket ID number EPA-HQ-OPP-2008-0258.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to dimethomorph, EPA considered exposure under the petitioned-
for tolerances as well as all existing dimethomorph tolerances in (40
CFR 180.493). EPA assessed dietary exposures from dimethomorph in food
as follows:
i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1 day or single exposure.
No such effects were identified in the toxicological studies for
dimethomorph; therefore, a quantitative acute dietary exposure
assessment is unnecessary.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data 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 used tolerance-level residues, the Dietary Exposure Evaluation
Model (DEEM) default processing factors, and assumed 100 percent crop
treated (PCT) for all proposed commodities.
iii. Cancer. Based on the results of the carcinogenicity studies in
rats and mice, dimethomorph has been classified as ``not likely to be
carcinogenic to humans;'' therefore, a quantitative exposure assessment
to evaluate cancer risk is unnecessary.
iv. Anticipated residue and PCT information. EPA did not use
anticipated residue and/or PCT information in the dietary assessment
for dimethomorph. Tolerance level residues and/or 100 PCT were assumed
for all food commodities.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for dimethomorph in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of dimethomorph. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
The First Index Reservoir Screening Tool (FIRST) Tier 1 model was
used to estimate concentrations for dimethomorph in surface water. The
Tier 1 Screening Concentration in Ground Water (SCI-GROW) model was
utilized to predict concentrations in ground water. The Tier 1 Generic
Estimated Environmental Concentration (GENEEC) model, from a previous
drinking water assessment, calculated another estimated drinking water
concentration (EDWC) for dimethomorph in surface water. The EDWCs of
dimethomorph for acute exposures are estimated to be 81.1 parts per
billion (ppb) for surface water and 0.264 ppb for ground water. For
chronic exposures, the non-cancer assessments are estimated to be 24.7
ppb for surface water, 28.5 ppb for a previously
[[Page 9354]]
determined surface water assessment, and 0.264 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the most conservative water concentration of value 28.5
ppb, from GENEEC modeling, 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). Dimethomorph is not
registered for any specific use patterns that would result in
residential exposure.
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
EPA has not found dimethomorph to share a common mechanism of
toxicity with any other substances, and dimethomorph does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
dimethomorph does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's website at https://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408(b)(2)(c) of FFDCA provides that EPA
shall apply an additional tenfold (10X) margin of safety for infants
and children in the case of threshold effects to account for prenatal
and postnatal toxicity and the completeness of the database on toxicity
and exposure unless EPA determines based on reliable data that a
different margin of safety will be safe for infants and children. This
additional margin of safety is commonly referred to as the Food Quality
Protection Act (FQPA) safety factor (SF). In applying this provision,
EPA either retains the default value of 10X, or uses a different
additional SF when reliable data available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity. The toxicology data on
dimethomorph provides no indication of enhanced sensitivity of infants
and children, based on the results from developmental studies conducted
with rats and rabbits, as well as a 2-generation reproduction study
conducted with rats. There were no toxic effects observed in either the
rat developmental toxicity, or the rat 2-generation reproductive
toxicity studies, that were observed at lower doses than those which
produced toxic effects in the parents. Further, clear NOAELs were
observed for all effects observed in fetuses. These NOAELs are well
above the NOAEL used as a point of departure in assessing the safety of
dimethomorph. No developmental toxicity was demonstrated in the rabbit
developmental toxicity study. Additionally, there is no evidence of
neurotoxicity.
3. Conclusion. EPA has determined that reliable data show the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1X. That decision is based on the following
findings:
i. The toxicity database for dimethomorph is complete except for
the immunotoxicity, acute neurotoxicity, and subchronic neurotoxicity
studies. Recent changes to 40 CFR part 158 make acute and subchronic
neurotoxicity testing (OPPTS Guideline 870.6200), and immunotoxicity
testing (OPPTS Guideline 870.7800) required for pesticide registration.
The available data for dimethomorph do not show potential for
immunotoxic or neurotoxic effects. Therefore, EPA does not believe that
conducting OPPTS Guideline 870.6200 neurotoxicity and OPPTS Guideline
870.7800 immunotoxicity studies will result in a NOAEL lower than the
NOAEL of 11 milligram/kilogram/day (mg/kg/day) already set for
dimethomorph. Consequently, an additional database uncertainty factor
(UF) does not need to be applied.
ii. There is no indication that dimethomorph is a neurotoxic
chemical and there is no need for a developmental neurotoxicity study
or additional UFs to account for neurotoxicity.
iii. The developmental and reproductive toxicity data did not
indicate increased quantitative or qualitative susceptibility of rats
or rabbits to in utero and/or postnatal exposure to dimethomorph. There
are no residual concerns regarding developmental effects in the young.
iv. There are no residual uncertainties identified in the exposure
databases. Dietary food exposure assessments were performed based on
100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to dimethomorph in drinking water. These assessments
will not underestimate the exposure and risks posed by dimethomorph.
E. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic pesticide exposures are
safe by comparing aggregate exposure estimates to the aPAD and cPAD.
The aPAD and cPAD represent the highest safe exposures, taking into
account all appropriate SFs. EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs. For linear cancer risks, EPA
calculates the probability of additional cancer cases given the
estimated aggregate exposure. Short-term, intermediate-term, and
chronic-term risks are evaluated by comparing the estimated aggregate
food, water, and residential exposure to the POD to ensure that the MOE
called for by the product of all applicable UFs is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute dietary consumption of food and
drinking water. No acute dietary endpoint was identified for any
segment of the U.S. population. Therefore, dimethomorph is not expected
to pose an acute risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
dimethomorph from food and water will utilize 20% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure. There are no residential uses for dimethomorph to consider.
3. Short-term and intermediate-term risk. Short-term and
intermediate-term aggregate exposure takes into account short-term and
intermediate-term residential exposure plus chronic exposure to food
and water (considered to be a background exposure level).
Dimethomorph is not registered for any use patterns that would
result in residential exposure. Therefore, the short-term and
intermediate-term aggregate risk is the sum of the risk from exposure
to dimethomorph through food and water and will not be greater than the
chronic aggregate risk.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in mice and rats at doses that were judged
to be adequate to assess the carcinogenic potential, dimethomorph was
classified
[[Page 9355]]
as ``not likely to be carcinogenic to humans.'' Therefore, dimethomorph
is not expected to pose a cancer risk to humans.
5. Determination of safety. Based on these risk assessments, EPA
concludes that there is a reasonable certainty that no harm will result
to the general population, or to infants and children from aggregate
exposure to dimethomorph residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (High-Performance Liquid
Chromatography using Ultraviolet detection (HPLC/UV) Method, (FAMS)
002-04) 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
There are no Canadian or Mexican maximum residue limits (MRLs)
established for residues of dimethomorph in crops associated with this
review. Codex MRLs have been finalized in grapes and grape, raisins at
2 and 5 ppm, respectively. However, the proposed tolerances in grape
and grape, raisin (3.5 and 6.0 ppm, respectively) cannot be harmonized
with the Codex MRLs on these commodities because field trial data shows
residue levels for grape that are higher than 2 ppm.
C. Revisions to Petitioned-For Tolerances
Based upon review of the data supporting the petition, EPA revised
the proposed tolerance for ginseng, from 0.85 ppm to 0.90 ppm. EPA
revised the proposed tolerance based on analysis 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. EPA also changed the commodity term from ``bean, lima'' to
``bean, lima, succulent'' because field trial data for dry lima beans
was not submitted. Use on lima beans is restricted to those varieties
intended for harvest as succulent seed. Use on lima beans is also
restricted to areas east of the Rocky Mountains, and will therefore be
established as a regional tolerance under paragraph (c) Tolerances with
regional registrations in Sec. 180.493. The proposed tolerance for
grape will also be restricted to a regional tolerance under
Sec. 180.493(c), since data were submitted to support use of
dimethomorph on grapes grown east of the Rocky Mountains. Since grapes
processed for raisin production are only grown west of the Rock
Mountains, the import tolerance for raisins will remain, and a
tolerance for raisin under Sec. 180.493(c) will not be established.
V. Conclusion
Therefore, tolerances are established for residues of dimethomorph
(E,Z) 4-[3-(4-chlorophenyl)-3-(3,4-dimethoxyphenyl)-1-oxo-2-
propenyl]morpholine, in or on ginseng at 0.90 ppm and turnip, greens at
20.0 ppm. Tolerances with regional registrations are established in or
on bean, lima, succulent at 0.6 ppm and grape at 3.5 ppm. This
regulation also deletes the existing tolerance for use in or on grape,
as the regional tolerance supersedes it. Finally, it increases the
existing import tolerance level for potato, wet peel from 0.15 to 0.20
ppm and re-establishes the tolerance for potato at 0.05 ppm.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances 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 final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis
of a petition under 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 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (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 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).
