II. Summary of Petitioned-For
Tolerance
In the Federal Register of July 20,
2011 (76 FR 43231) (FRL–8880–1), 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 0F7800) by BASF
Corporation, P.O. Box 13528, Research
Triangle Park, NC 27709. The petition
requested that EPA amend 40 CFR part
180 by raising tolerances for residues of
the fungicide dimethomorph, in or on
brassica, head and stem, subgroup 5A
from 2.0 ppm to 5.0 ppm; brassica, leafy
greens, subgroup 5B from 20.0 ppm to
30.0 ppm; green onion, subgroup 3B
from 2.0 ppm to 11.0 ppm. The petition
also requested that 40 CFR part 180 be
amended by establishing a tolerance for
the residues of the fungicide
dimethomorph, in or on vegetable, leafy
at 16 ppm (PP 0F7816). The notice
E:\FR\FM\04MYR1.SGM

Federal Register / Vol. 77, No. 87 / Friday, May 4, 2012 / Rules and Regulations
referenced a summary of the petition
prepared by BASF Corporation, the
registrant, which is available in the
docket, https://www.regulations.gov.
There were no comments received in
response to the notice of filing.
In the Federal Register of October 27,
2010 (75 FR 66092) (FRL–8848–3), 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 0F7751) by BASF
Corporation, P.O. Box 13528, Research
Triangle Park, NC 27709. The petition
requested that EPA establish a tolerance
for residues of the fungicide
dimethomorph, in or on grape at 3.5
ppm. The notice referenced a summary
of the petition prepared by BASF
Corporation, the registrant, which is
available in the docket, https://
www.regulations.gov. One comment was
received on the notice of filing. EPA’s
response to these comments is
discussed in Unit IV.C.
Based upon review of the data
supporting the petitions, EPA has
revised the proposed tolerance level and
commodity definition for vegetable,
bulb, group 3 and removed the
established tolerance for the regional
registration for grape. Tolerances for the
national registration for grape and
onion, bulb subgroup 3–07A were
lowered. Tolerances for brassica, head
and stem, subgroup 5A; brassica, leafy
greens, subgroup 5B; vegetable, leafy
except brassica, group 4; onion, green,
subgroup 3–07B were raised. Tolerances
for grape, raisin were established for
domestic registrations and were also
raised. EPA is also establishing
rotational crop tolerances for wheat,
forage; wheat, hay; and wheat, straw.
EPA has made various changes to the
commodity definitions and tolerance
levels sought in the petition and also is
establishing rotational crop tolerances.
The reason 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
VerDate Mar<15>2010
15:04 May 03, 2012
Jkt 226001
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 FFDCA section
408(b)(2)(D), and the factors specified in
FFDCA section 408(b)(2)(D), EPA has
reviewed the available scientific data
and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure for dimethomorph
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with dimethomorph 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.
Dimethomorph has low acute toxicity
via the oral and dermal routes of
exposure. Chronic risk is regulated
based on effects seen in body weight
decrements and liver effects in the
female rat. There was no evidence of
increased incidence of any neoplasms at
the limit dose tested in carcinogenicity
studies tested in rats and mice.
Dimethomorph is classified as ‘‘not
likely’’ to be a human carcinogen based
on the lack of evidence of
carcinogenicity in carcinogenicity
studies in rats and mice. The available
data for dimethomorph does not show
evidence of neurotoxicity. There is a
subchronic neurotoxicity study
available which demonstrated no
neurotoxic effects in the study. In
addition, neither the subchronic nor
chronic toxicity studies in rats or dogs,
PO 00000
Frm 00047
Fmt 4700
Sfmt 4700
26463
nor the developmental toxicity studies
indicated that the nervous system was
affected by treatment with
dimethomorph.
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
(NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the
toxicity studies can be found at https://
www.regulations.gov in document
‘‘Dimethomorph: Human Health Risk
Assessment to Support Amended Use
on Grapes, Bulb Vegetables, Leafy
Brassica Vegetables, and Leafy
Vegetables,’’ pp. 35–38 in docket ID
number EPA–HQ–OPP–2011–0388.
B. Toxicological Points of Departure/
Levels of Concern
Once a pesticide’s toxicological
profile is determined, EPA identifies
toxicological points of departure (POD)
and levels of concern to use in
evaluating the risk posed by human
exposure to the pesticide. For hazards
that have a threshold below which there
is no appreciable risk, the toxicological
POD is used as the basis for derivation
of reference values for risk assessment.
PODs are developed based on a careful
analysis of the doses in each
toxicological study to determine the
dose at which no adverse effects are
observed (the NOAEL) and the lowest
dose at which adverse effects of concern
are identified (the LOAEL). Uncertainty/
safety factors are used in conjunction
with the POD to calculate a safe
exposure level—generally referred to as
a population-adjusted dose (PAD) or a
reference dose (RfD)—and a safe margin
of exposure (MOE). 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
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/

endpoints for dimethomorph used for
human risk assessment is shown in the

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 toxic effects attributable to
a single dose were observed 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 USDA 1994–1996 and 1998
CSFII. As to residue levels in food, EPA
assumed tolerance-level residues and
100 percent crop treated (PCT). Dietary
Evaluation Exposure Model (DEEM)
default processing factors were used.
iii. Cancer. Based on the data
summarized in Unit III.A.,
dimethomorph has been classified as
‘‘not likely’’ to be a human carcinogen.
EPA has concluded that dimethomorph
does not pose a cancer risk to humans.
Therefore, a dietary exposure
assessment for the purpose of assessing
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
VerDate Mar<15>2010
15:04 May 03, 2012
Jkt 226001
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.
Based on the First Index Reservoir
Screening Tool (FIRST), and Screening
Concentration in Ground Water (SCI–
GROW) models, the estimated drinking
water concentrations (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 for non-cancer
assessments are estimated to be 24.7
ppb for surface water 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 water concentration of value 24.7
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).
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 Web site 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
E:\FR\FM\04MYR1.SGM
04MYR1
Federal Register / Vol. 77, No. 87 / Friday, May 4, 2012 / Rules and Regulations
provision, EPA either retains the default
value of 10X, or uses a different
additional safety factor when reliable
data available to EPA support the choice
of a different factor.
2. Prenatal and postnatal sensitivity.
The available data did not provide
evidence of any increased susceptibility
in the offspring in either of the two
developmental toxicity studies or in the
2-generation reproduction study. In
either of these two studies toxicity was
not seen in the offspring occurring at
doses lower than in the parent in any of
the studies. Additionally, the effects
seen in the young were qualitatively
similar to those in the parents.
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.
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. There is no evidence that
dimethomorph results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats in the 2-generation
reproduction study.
iv. There are no residual uncertainties
identified in the exposure databases.
The unrefined chronic dietary risk
assessment used tolerance level
residues, included modeled drinking
water estimates, assumed 100 PCT, and
incorporated DEEM default processing
factors. 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.
erowe on DSK2VPTVN1PROD with RULES
E. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic dietary pesticide exposures are
safe by comparing aggregate exposure
estimates to the acute PAD (aPAD) and
chronic PAD (cPAD). For linear cancer
risks, EPA calculates the lifetime
probability of acquiring cancer given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the appropriate
PODs to ensure that an adequate MOE
exists.
VerDate Mar<15>2010
15:04 May 03, 2012
Jkt 226001
1. Acute risk. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effect resulting from
a single oral exposure was identified
and no acute dietary endpoint was
selected. 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 27% of
the cPAD for children 1–2 years old the
population group receiving the greatest
exposure. There are no residential uses
for dimethomorph and thus residential
exposure to residues of dimethomorph
is not expected.
3. Short-term risk. Short-term
aggregate exposure takes into account
short-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 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. Intermediate-term risk.
Intermediate-term aggregate exposure
takes into account 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
intermediate-term residential exposure.
Therefore, the intermediate-term
aggregate risk is the sum of the risk from
exposure to dimethomorph through
food and water, which has already been
addressed, and will not be greater than
the chronic aggregate risk.
5. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
dimethomorph is not expected to pose
a cancer risk to humans.
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
dimethomorph residues.

Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level.
The Codex has established MRLs for
dimethomorph in or on grape at 2 ppm;
and grape, raisin at 5 ppm. These MRLs
are different than the tolerances being
established for dimethomorph in this
action because the MRLs are based on
residue data derived from Europe.
C. Response to Comments
One comment was received from a
private citizen (in reference to tolerance
petition 0F7751) who encouraged the
Agency to continue to reduce the risk to
human health and the environment
from pesticide usage. The Agency
recognizes that some individuals believe
that pesticide use should not be
permitted. However, under the existing
legal framework provided by section
408 of the Federal Food, Drug and
Cosmetic Act (FFDCA), EPA is
authorized to establish pesticide
tolerances or exemptions where persons
seeking such tolerances or exemptions
have demonstrated that the pesticide
meets the safety standard imposed by
the statute.
D. Revisions to Petitioned-For
Tolerances
The crop group regulations (40 CFR
180.41) were recently amended
pertaining to Crop Group 3—Bulb
Vegetables, and the revised Crop group
is designated Crop group 3–07 Bulb
Vegetable. The revised crop group now
contains two subgroups: Bulb, subgroup
E:\FR\FM\04MYR1.SGM
04MYR1
26466
Federal Register / Vol. 77, No. 87 / Friday, May 4, 2012 / Rules and Regulations
3–07A and onion, green, subgroup 3–
07B. Because BASF proposed to modify
its existing Crop Group 3 tolerance by
adding a revised green onion tolerance,
EPA has determined it is appropriate to
establish both onion, bulb subgroup 3–
07A and onion, green, subgroup 3–07B
tolerances rather than a Crop Group 3
tolerance and a green onion tolerance.
Based on analysis of residue levels from
crop field trail data and tolerance
calculation procedures, EPA is setting
the onion, bulb subgroup 3–07A
tolerance at 0.6 ppm and the onion,
green, subgroup 3–07B tolerance at 15
ppm. EPA is removing the existing Crop
Group 3 tolerance.
Additionally, based on analysis of
residue levels from crop field trail data
and tolerance calculation procedures,
EPA is raising tolerance levels for grape,
raisin; brassica, head and stem,
subgroup 5A; brassica, leafy greens,
subgroup 5B; and vegetable, leafy,
except brassica, group 4. For the same
reason, EPA is lowering the tolerance
for grape. Additionally, because the
Agency is amending the BASF
registration to allow use on grapes in the
U.S., EPA is removing the footnote in
the tolerance stating that such a
registration does not exist.
Subsequent to the filing of the
petition, the petitioner requested that
the Agency establish tolerances in cereal
grain commodities (forage, hay and
straw) that are rotated to fields
following use dimethomorph on
commodities covered by the tolerances
established in this action. The Agency
determined that rotated crop tolerances
would be appropriate for wheat, forage;
wheat, hay; and wheat, straw.

V. Conclusion
Therefore, amended tolerances are
established for residues of
dimethomorph, in or on brassica, head
and stem, subgroup 5A at 6.0 ppm;
brassica, leafy greens, subgroup 5B at
30.0 ppm; onion, bulb subgroup 3–07A
at 0.6 ppm; onion, green, subgroup 3–
07B at 15.0 ppm; grape at 3.0 ppm; and
grape, raisin at 7.0 ppm. A tolerance is
established for residues of
dimethomorph, in or on vegetable, leafy
except brassica, group 4 at 30.0 ppm.
This regulation also establishes
tolerances for the indirect or inadvertent
residues of dimethomorph, in or on
wheat, forage at 0.15 ppm; wheat hay at
0.15 ppm and wheat, straw at 0.4 ppm.
Furthermore, this regulation removes
established tolerances on vegetable,
bulb, group 3 and footnote pertaining
the lack of a registration for use on
grapes.

VI. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this 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 FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of FFDCA section 408(n)(4). 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
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Pub. L. 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), 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. Summary of Petitioned-For Tolerance
In the Federal Register of July 20, 2011 (76 FR 43231) (FRL-8880-
1), 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
0F7800) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC
27709. The petition requested that EPA amend 40 CFR part 180 by raising
tolerances for residues of the fungicide dimethomorph, in or on
brassica, head and stem, subgroup 5A from 2.0 ppm to 5.0 ppm; brassica,
leafy greens, subgroup 5B from 20.0 ppm to 30.0 ppm; green onion,
subgroup 3B from 2.0 ppm to 11.0 ppm. The petition also requested that
40 CFR part 180 be amended by establishing a tolerance for the residues
of the fungicide dimethomorph, in or on vegetable, leafy at 16 ppm (PP
0F7816). The notice
[[Page 26463]]
referenced a summary of the petition prepared by BASF Corporation, the
registrant, which is available in the docket, https://www.regulations.gov. There were no comments received in response to the
notice of filing.
In the Federal Register of October 27, 2010 (75 FR 66092) (FRL-
8848-3), 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
0F7751) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC
27709. The petition requested that EPA establish a tolerance for
residues of the fungicide dimethomorph, in or on grape at 3.5 ppm. The
notice referenced a summary of the petition prepared by BASF
Corporation, the registrant, which is available in the docket, https://www.regulations.gov. One comment was received on the notice of filing.
EPA's response to these comments is discussed in Unit IV.C.
Based upon review of the data supporting the petitions, EPA has
revised the proposed tolerance level and commodity definition for
vegetable, bulb, group 3 and removed the established tolerance for the
regional registration for grape. Tolerances for the national
registration for grape and onion, bulb subgroup 3-07A were lowered.
Tolerances for brassica, head and stem, subgroup 5A; brassica, leafy
greens, subgroup 5B; vegetable, leafy except brassica, group 4; onion,
green, subgroup 3-07B were raised. Tolerances for grape, raisin were
established for domestic registrations and were also raised. EPA is
also establishing rotational crop tolerances for wheat, forage; wheat,
hay; and wheat, straw. EPA has made various changes to the commodity
definitions and tolerance levels sought in the petition and also is
establishing rotational crop tolerances. The reason 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 FFDCA section 408(b)(2)(D), and the factors
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available
scientific data and other relevant information in support of this
action. EPA has sufficient data to assess the hazards of and to make a
determination on aggregate exposure for dimethomorph including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with dimethomorph 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.
Dimethomorph has low acute toxicity via the oral and dermal routes
of exposure. Chronic risk is regulated based on effects seen in body
weight decrements and liver effects in the female rat. There was no
evidence of increased incidence of any neoplasms at the limit dose
tested in carcinogenicity studies tested in rats and mice. Dimethomorph
is classified as ``not likely'' to be a human carcinogen based on the
lack of evidence of carcinogenicity in carcinogenicity studies in rats
and mice. The available data for dimethomorph does not show evidence of
neurotoxicity. There is a subchronic neurotoxicity study available
which demonstrated no neurotoxic effects in the study. In addition,
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.
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 (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in document ``Dimethomorph: Human Health Risk
Assessment to Support Amended Use on Grapes, Bulb Vegetables, Leafy
Brassica Vegetables, and Leafy Vegetables,'' pp. 35-38 in docket ID
number EPA-HQ-OPP-2011-0388.
B. Toxicological Points of Departure/Levels of Concern
Once a pesticide's toxicological profile is determined, EPA
identifies toxicological points of departure (POD) and levels of
concern to use in evaluating the risk posed by human exposure to the
pesticide. For hazards that have a threshold below which there is no
appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). 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 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 is shown in the Table this unit.

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 toxic effects
attributable to a single dose were observed 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 USDA 1994-1996
and 1998 CSFII. As to residue levels in food, EPA assumed tolerance-
level residues and 100 percent crop treated (PCT). Dietary Evaluation
Exposure Model (DEEM) default processing factors were used.
iii. Cancer. Based on the data summarized in Unit III.A.,
dimethomorph has been classified as ``not likely'' to be a human
carcinogen. EPA has concluded that dimethomorph does not pose a cancer
risk to humans. Therefore, a dietary exposure assessment for the
purpose of assessing 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.
Based on the First Index Reservoir Screening Tool (FIRST), and
Screening Concentration in Ground Water (SCI-GROW) models, the
estimated drinking water concentrations (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 for non-cancer assessments are estimated to
be 24.7 ppb for surface water 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 water concentration of
value 24.7 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). 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 Web site 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
[[Page 26465]]
provision, EPA either retains the default value of 10X, or uses a
different additional safety factor when reliable data available to EPA
support the choice of a different factor.
2. Prenatal and postnatal sensitivity. The available data did not
provide evidence of any increased susceptibility in the offspring in
either of the two developmental toxicity studies or in the 2-generation
reproduction study. In either of these two studies toxicity was not
seen in the offspring occurring at doses lower than in the parent in
any of the studies. Additionally, the effects seen in the young were
qualitatively similar to those in the parents.
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.
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. There is no evidence that dimethomorph results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats in the 2-generation reproduction
study.
iv. There are no residual uncertainties identified in the exposure
databases. The unrefined chronic dietary risk assessment used tolerance
level residues, included modeled drinking water estimates, assumed 100
PCT, and incorporated DEEM default processing factors. 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 dietary pesticide
exposures are safe by comparing aggregate exposure estimates to the
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA
calculates the lifetime probability of acquiring cancer given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the appropriate PODs to ensure that an
adequate MOE exists.
1. Acute risk. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effect resulting from a single oral exposure
was identified and no acute dietary endpoint was selected. 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 27% of the cPAD for
children 1-2 years old the population group receiving the greatest
exposure. There are no residential uses for dimethomorph and thus
residential exposure to residues of dimethomorph is not expected.
3. Short-term risk. Short-term aggregate exposure takes into
account short-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 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. Intermediate-term risk. Intermediate-term aggregate exposure
takes into account 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 intermediate-term residential exposure. Therefore, the
intermediate-term aggregate risk is the sum of the risk from exposure
to dimethomorph through food and water, which has already been
addressed, and will not be greater than the chronic aggregate risk.
5. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, dimethomorph is not expected to pose a cancer risk to humans.
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 dimethomorph residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
FAMS-002-04 which utilizes high pressure liquid chromatography with
ultraviolet detection (HPLC/UV) 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; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level.
The Codex has established MRLs for dimethomorph in or on grape at 2
ppm; and grape, raisin at 5 ppm. These MRLs are different than the
tolerances being established for dimethomorph in this action because
the MRLs are based on residue data derived from Europe.
C. Response to Comments
One comment was received from a private citizen (in reference to
tolerance petition 0F7751) who encouraged the Agency to continue to
reduce the risk to human health and the environment from pesticide
usage. The Agency recognizes that some individuals believe that
pesticide use should not be permitted. However, under the existing
legal framework provided by section 408 of the Federal Food, Drug and
Cosmetic Act (FFDCA), EPA is authorized to establish pesticide
tolerances or exemptions where persons seeking such tolerances or
exemptions have demonstrated that the pesticide meets the safety
standard imposed by the statute.
D. Revisions to Petitioned-For Tolerances
The crop group regulations (40 CFR 180.41) were recently amended
pertaining to Crop Group 3--Bulb Vegetables, and the revised Crop group
is designated Crop group 3-07 Bulb Vegetable. The revised crop group
now contains two subgroups: Bulb, subgroup
[[Page 26466]]
3-07A and onion, green, subgroup 3-07B. Because BASF proposed to modify
its existing Crop Group 3 tolerance by adding a revised green onion
tolerance, EPA has determined it is appropriate to establish both
onion, bulb subgroup 3-07A and onion, green, subgroup 3-07B tolerances
rather than a Crop Group 3 tolerance and a green onion tolerance. Based
on analysis of residue levels from crop field trail data and tolerance
calculation procedures, EPA is setting the onion, bulb subgroup 3-07A
tolerance at 0.6 ppm and the onion, green, subgroup 3-07B tolerance at
15 ppm. EPA is removing the existing Crop Group 3 tolerance.
Additionally, based on analysis of residue levels from crop field
trail data and tolerance calculation procedures, EPA is raising
tolerance levels for grape, raisin; brassica, head and stem, subgroup
5A; brassica, leafy greens, subgroup 5B; and vegetable, leafy, except
brassica, group 4. For the same reason, EPA is lowering the tolerance
for grape. Additionally, because the Agency is amending the BASF
registration to allow use on grapes in the U.S., EPA is removing the
footnote in the tolerance stating that such a registration does not
exist.
Subsequent to the filing of the petition, the petitioner requested
that the Agency establish tolerances in cereal grain commodities
(forage, hay and straw) that are rotated to fields following use
dimethomorph on commodities covered by the tolerances established in
this action. The Agency determined that rotated crop tolerances would
be appropriate for wheat, forage; wheat, hay; and wheat, straw.
V. Conclusion
Therefore, amended tolerances are established for residues of
dimethomorph, in or on brassica, head and stem, subgroup 5A at 6.0 ppm;
brassica, leafy greens, subgroup 5B at 30.0 ppm; onion, bulb subgroup
3-07A at 0.6 ppm; onion, green, subgroup 3-07B at 15.0 ppm; grape at
3.0 ppm; and grape, raisin at 7.0 ppm. A tolerance is established for
residues of dimethomorph, in or on vegetable, leafy except brassica,
group 4 at 30.0 ppm. This regulation also establishes tolerances for
the indirect or inadvertent residues of dimethomorph, in or on wheat,
forage at 0.15 ppm; wheat hay at 0.15 ppm and wheat, straw at 0.4 ppm.
Furthermore, this regulation removes established tolerances on
vegetable, bulb, group 3 and footnote pertaining the lack of a
registration for use on grapes.
VI. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA section 408(d)
in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled ``Regulatory Planning and
Review'' (58 FR 51735, October 4, 1993). Because this 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 FFDCA section 408(d), such as the tolerance in this
final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). 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) (Pub. L. 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), 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).
