II. Summary of Petitioned-For
Tolerance
In the Federal Register of April 6,
2015 (80 FR 18327) (FRL–9924–00),
EPA issued a document pursuant to
FFDCA section 408(d)(3), 21 U.S.C.
346a(d)(3), announcing the filing of a
pesticide petition (PP 4E8335) by IR–4,
500 College Road East, Suite 201 W.,
Princeton, NJ 08540. The petition
requested that 40 CFR part 180 be
amended by establishing tolerances for
residues of residues of the sum of
zoxamide (3, 5-dichloro-N-(3-chloro-1ethyl-1-methyl-2-oxopropyl)-4methylbenzamide) and its metabolites
3,5-dichloro-1,4-benzenedicarboxylic
acid (RH–1455 and RH–141455) and
3,5-dichloro-4-hydroxymethylbenzoic
acid (RH–1452 and RH–141452)
calculated as the stoichiometric
equivalent of zoxamide in or on the raw
agricultural commodity ginseng at 0.30
parts per million (ppm) and vegetable,
tuberous and corm, subgroup 1C at
0.060 ppm. In addition, IR–4 requested
to establish tolerances for residues,
determined by measuring only
zoxamide (3,5-dichloro-N-(3-chloro-1ethyl-1-methyl-2-oxypropyl)-4methylbenzamide, in or on the raw
agricultural commodity tomato
subgroup 8–10A at 2.0 ppm and fruit,
small, vine climbing, except fuzzy
kiwifruit, subgroup 13–07F at 5.0 ppm.
IR–4 also proposed, upon the approval
of the aforementioned tolerances, to
remove established tolerances for grape
at 3.0 ppm; tomato at 2.0 ppm; and
potato at 0.060 ppm. That document
referenced a summary of the petition

response to the notice of filing.
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 zoxamide
including exposure resulting from the
tolerances established by this action.
EPA’s assessment of exposures and risks
associated with zoxamide 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.
In repeat dose oral and dermal
toxicity studies in rats, there were no
indications of systemic toxicity up to
the highest dose tested (HDT); most of
the highest doses were at or above the
limit dose (1,000 milligrams/kilogram/
day (mg/kg/day)). In the repeat dose oral
toxicity studies in dogs, effects included
increased liver and thyroid weights,
liver histopathology (i.e., hepatocellular
hypertrophy), and increased alkaline
phosphatase.

08MRR1
Federal Register / Vol. 81, No. 45 / Tuesday, March 8, 2016 / Rules and Regulations
asabaliauskas on DSK3SPTVN1PROD with RULES
In the rat and rabbit prenatal
developmental toxicity studies, there
were no indications of susceptibility, as
there was neither maternal nor
developmental toxicity up to the HDT.
In the rat reproduction study, there were
no indications of susceptibility, since
parental effects (i.e., decreased maternal
body weight) occurred in the absence of
reproductive or offspring toxicity.
Zoxamide has been classified as ‘‘not
likely to be carcinogenic in humans’’
based on the results of carcinogenicity
studies in rats and mice. In the acute
and subchronic neurotoxicity studies,
there were no indications of
neurotoxicity up to the HDT.
Specific information on the studies
received and the nature of the adverse
effects caused by zoxamide 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 the document
titled ‘‘Zoxamide. Human Health
Aggregate Risk Assessment for the
Proposed New Uses on Ginseng, Tomato
Subgroup 8–10A; Small Fruit, Vine
Climbing, Except Fuzzy Kiwifruit,
Subgroup 13–07F; and Tuberous and
Corm Vegetable Subgroup 1C’’ on page
25 in docket ID number EPA–HQ–OPP–
2014–0922.
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

assessment process, see https://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides.
A summary of the toxicological
endpoints for zoxamide used for human
risk assessment is discussed in Unit
III.B. of the final rule published in the
Federal Register of July 18, 2014 (79 FR
41911) (FRL–9913–35).
C. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to zoxamide, EPA considered
exposure under the petitioned-for
tolerances as well as all existing
zoxamide tolerances in 40 CFR 180.567.
EPA assessed dietary exposures from
zoxamide 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 zoxamide;
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 United States Department of
Agriculture’s (USDA’s) 2003–2008
National Health and Nutrition
Examination Survey, What We Eat in
America (NHANES/WWEIA) database.
As to residue levels in food, EPA
assumed tolerance-level residues and
100 percent crop treated (PCT) for all
established and proposed commodities.
The assessment also utilized default
processing factors from the Dietary
Exposure Evaluation Model—Food
Commodity Intake Database (DEEM–
FCID) version 7.81 except for raisin and
potato granules/flakes, where the
processing factor was set at 1.
iii. Cancer. Based on the data
summarized in Unit III.A., EPA has
concluded that zoxamide 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 or PCT information
in the dietary assessment for zoxamide.
Tolerance level residues and 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 zoxamide and its major metabolites
in drinking water. These simulation
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
12013
models take into account data on the
physical, chemical, and fate/transport
characteristics of zoxamide and its
metabolites. Further information
regarding EPA drinking water models
used in pesticide exposure assessment
can be found at
https://www2.epa.gov/pesticide-scienceand-assessing-pesticide-risks/aboutwater-exposure-models-used-pesticide.
Based on the Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Pesticide
Root Zone Model Ground Water (PRZM
GW) model, the estimated drinking
water concentrations (EDWCs) of
zoxamide and its major metabolites for
chronic exposures are estimated to be
22.84 parts per billion (ppb) for surface
water and 65.8 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 65.8 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). Zoxamide
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 zoxamide to share
a common mechanism of toxicity with
any other substances, and zoxamide
does not appear to produce a toxic
metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that zoxamide 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://
www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.

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 Safety
Factor (FQPA SF). In applying this
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.
There was no evidence for increased
susceptibility following prenatal
exposure in prenatal developmental
toxicity studies in rats and rabbits.
Additionally, there was no evidence for
increased susceptibility following preor postnatal exposure in the
reproduction and fertility effects study
in rats.
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 1×. That decision is
based on the following findings:
i. The toxicity database for zoxamide
is complete.
ii. There is no indication that
zoxamide 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
zoxamide 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 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 zoxamide in
drinking water. These assessments will
not underestimate the exposure and
risks posed by zoxamide.
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
VerDate Sep<11>2014
16:05 Mar 07, 2016
Jkt 238001
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, zoxamide 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 zoxamide from
food and water will utilize 6.3% of the
cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. There are no residential uses
for zoxamide.
3. Short- and intermediate-term risk.
Short- and intermediate-term aggregate
exposure takes into account short- and
intermediate-term residential exposure
plus chronic exposure to food and water
(considered to be a background
exposure level).
A short- and intermediate-term
adverse effect was identified; however,
zoxamide is not registered for any use
patterns that would result in either
short- or intermediate-term residential
exposure. Short- and intermediate-term
risk is assessed based on short- and
intermediate-term residential exposure
plus chronic dietary exposure. Because
there is no short- or intermediate-term
residential exposure and chronic dietary
exposure has already been assessed
under the appropriately protective
cPAD (which is at least as protective as
the POD used to assess short- or
intermediate-term risk), no further
assessment of short- or intermediateterm risk is necessary, and EPA relies on
the chronic dietary risk assessment for
evaluating short- and intermediate-term
risk for zoxamide.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
zoxamide 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 zoxamide
residues.

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 tolerances being established for
the tomato subgroup 8–10A and the
small vine climbing fruit, except fuzzy
kiwifruit, subgroup 13–07F are
harmonized with established Codex
MRLs on tomato and grape,
respectively. The tolerance being
established for the tuberous and corm
vegetable subgroup 1C at 0.06 ppm is
not harmonized with a Codex MRL on
potato at 0.02 ppm. The underlying
residue data and residue definition used
to support the Subgroup 1C tolerance
supports a tolerance recommendation
that is higher than the established
Codex MRL on potato at 0.02 ppm.
There is not a Codex MRL for ginseng.
V. Conclusion
Therefore, tolerances are established
for residues of zoxamide (3,5-dichloroN-(3-chloro-1-ethyl-1-methyl-2oxopropyl)-4-methylbenzamide) and its
metabolites 3,5-dichloro-1,4benzenedicarboxylic acid (RH–1455 and
RH–141455) and 3,5-dichloro-4hydroxymethylbenzoic acid (RH–1452
and RH–141452) calculated as the

stoichiometric equivalent of zoxamide
in or on the raw agricultural commodity
ginseng at 0.30 ppm and vegetable,

established for residues, determined by
measuring only zoxamide (3,5-dichloroN-(3-chloro-1-ethyl-1-methyl-2oxypropyl)-4-methylbenzamide, in or on
raw agricultural commodity tomato
subgroup 8–10A at 2.0 ppm and fruit,
small vine climbing, except fuzzy
kiwifruit, subgroup 13–07F at 5.0 ppm.
Lastly, upon the establishment of the
aforementioned tolerances, the
established tolerances for grape at 3.0
ppm; tomato at 2.0 ppm; and potato at
0.060 ppm are removed as unnecessary.
VI. Statutory and Executive Order
Reviews
This action 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 action
has been exempted from review under
Executive Order 12866, this action 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 action 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 action 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
VerDate Sep<11>2014

Jkt 238001
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 action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
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
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), 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 the rule in the Federal
Register. This action 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 April 6, 2015 (80 FR 18327) (FRL-9924-
00), EPA issued a document pursuant to FFDCA section 408(d)(3), 21
U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP
4E8335) by IR-4, 500 College Road East, Suite 201 W., Princeton, NJ
08540. The petition requested that 40 CFR part 180 be amended by
establishing tolerances for residues of residues of the sum of zoxamide
(3, 5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-4-
methylbenzamide) and its metabolites 3,5-dichloro-1,4-
benzenedicarboxylic acid (RH-1455 and RH-141455) and 3,5-dichloro-4-
hydroxymethylbenzoic acid (RH-1452 and RH-141452) calculated as the
stoichiometric equivalent of zoxamide in or on the raw agricultural
commodity ginseng at 0.30 parts per million (ppm) and vegetable,
tuberous and corm, subgroup 1C at 0.060 ppm. In addition, IR-4
requested to establish tolerances for residues, determined by measuring
only zoxamide (3,5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxypropyl)-
4- methylbenzamide, in or on the raw agricultural commodity tomato
subgroup 8-10A at 2.0 ppm and fruit, small, vine climbing, except fuzzy
kiwifruit, subgroup 13-07F at 5.0 ppm. IR-4 also proposed, upon the
approval of the aforementioned tolerances, to remove established
tolerances for grape at 3.0 ppm; tomato at 2.0 ppm; and potato at 0.060
ppm. That document referenced a summary of the petition prepared by
Gowan Company, the registrant, which is available in the docket, https://www.regulations.gov. There were no comments received in response to
the notice of filing.
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 zoxamide including exposure
resulting from the tolerances established by this action. EPA's
assessment of exposures and risks associated with zoxamide 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.
In repeat dose oral and dermal toxicity studies in rats, there were
no indications of systemic toxicity up to the highest dose tested
(HDT); most of the highest doses were at or above the limit dose (1,000
milligrams/kilogram/day (mg/kg/day)). In the repeat dose oral toxicity
studies in dogs, effects included increased liver and thyroid weights,
liver histopathology (i.e., hepatocellular hypertrophy), and increased
alkaline phosphatase.
[[Page 12013]]
In the rat and rabbit prenatal developmental toxicity studies,
there were no indications of susceptibility, as there was neither
maternal nor developmental toxicity up to the HDT. In the rat
reproduction study, there were no indications of susceptibility, since
parental effects (i.e., decreased maternal body weight) occurred in the
absence of reproductive or offspring toxicity.
Zoxamide has been classified as ``not likely to be carcinogenic in
humans'' based on the results of carcinogenicity studies in rats and
mice. In the acute and subchronic neurotoxicity studies, there were no
indications of neurotoxicity up to the HDT.
Specific information on the studies received and the nature of the
adverse effects caused by zoxamide as well as the no-observed-adverse-
effect-level (NOAEL) and the lowest-observed-adverse-effect-level
(LOAEL) from the toxicity studies can be found at https://www.regulations.gov in the document titled ``Zoxamide. Human Health
Aggregate Risk Assessment for the Proposed New Uses on Ginseng, Tomato
Subgroup 8-10A; Small Fruit, Vine Climbing, Except Fuzzy Kiwifruit,
Subgroup 13-07F; and Tuberous and Corm Vegetable Subgroup 1C'' on page
25 in docket ID number EPA-HQ-OPP-2014-0922.
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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
A summary of the toxicological endpoints for zoxamide used for
human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of July 18, 2014 (79 FR 41911) (FRL-
9913-35).
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to zoxamide, EPA considered exposure under the petitioned-for
tolerances as well as all existing zoxamide tolerances in 40 CFR
180.567. EPA assessed dietary exposures from zoxamide 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
zoxamide; 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 United States
Department of Agriculture's (USDA's) 2003-2008 National Health and
Nutrition Examination Survey, What We Eat in America (NHANES/WWEIA)
database. As to residue levels in food, EPA assumed tolerance-level
residues and 100 percent crop treated (PCT) for all established and
proposed commodities. The assessment also utilized default processing
factors from the Dietary Exposure Evaluation Model--Food Commodity
Intake Database (DEEM-FCID) version 7.81 except for raisin and potato
granules/flakes, where the processing factor was set at 1.
iii. Cancer. Based on the data summarized in Unit III.A., EPA has
concluded that zoxamide 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 or PCT information in the dietary assessment for
zoxamide. Tolerance level residues and 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 zoxamide and its major metabolites in drinking water.
These simulation models take into account data on the physical,
chemical, and fate/transport characteristics of zoxamide and its
metabolites. Further information regarding EPA drinking water models
used in pesticide exposure assessment can be found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM
GW) model, the estimated drinking water concentrations (EDWCs) of
zoxamide and its major metabolites for chronic exposures are estimated
to be 22.84 parts per billion (ppb) for surface water and 65.8 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 65.8 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). Zoxamide 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 zoxamide to share a common mechanism of toxicity
with any other substances, and zoxamide does not appear to produce a
toxic metabolite produced by other substances. For the purposes of this
tolerance action, therefore, EPA has assumed that zoxamide 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
[[Page 12014]]
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 Safety Factor (FQPA SF). In applying this 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. There was no evidence for
increased susceptibility following prenatal exposure in prenatal
developmental toxicity studies in rats and rabbits. Additionally, there
was no evidence for increased susceptibility following pre- or
postnatal exposure in the reproduction and fertility effects study in
rats.
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 zoxamide is complete.
ii. There is no indication that zoxamide 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 zoxamide 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 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 zoxamide in drinking water. These assessments
will not underestimate the exposure and risks posed by zoxamide.
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,
zoxamide 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
zoxamide from food and water will utilize 6.3% of the cPAD for children
1-2 years old, the population group receiving the greatest exposure.
There are no residential uses for zoxamide.
3. Short- and intermediate-term risk. Short- and intermediate-term
aggregate exposure takes into account short- and intermediate-term
residential exposure plus chronic exposure to food and water
(considered to be a background exposure level).
A short- and intermediate-term adverse effect was identified;
however, zoxamide is not registered for any use patterns that would
result in either short- or intermediate-term residential exposure.
Short- and intermediate-term risk is assessed based on short- and
intermediate-term residential exposure plus chronic dietary exposure.
Because there is no short- or intermediate-term residential exposure
and chronic dietary exposure has already been assessed under the
appropriately protective cPAD (which is at least as protective as the
POD used to assess short- or intermediate-term risk), no further
assessment of short- or intermediate-term risk is necessary, and EPA
relies on the chronic dietary risk assessment for evaluating short- and
intermediate-term risk for zoxamide.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, zoxamide 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 zoxamide residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (Gas chromatography with electron
capture detection (GC/ECD) and GC with mass selective detection (GC/

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 tolerances being established for the tomato subgroup 8-10A and
the small vine climbing fruit, except fuzzy kiwifruit, subgroup 13-07F
are harmonized with established Codex MRLs on tomato and grape,
respectively. The tolerance being established for the tuberous and corm
vegetable subgroup 1C at 0.06 ppm is not harmonized with a Codex MRL on
potato at 0.02 ppm. The underlying residue data and residue definition
used to support the Subgroup 1C tolerance supports a tolerance
recommendation that is higher than the established Codex MRL on potato
at 0.02 ppm. There is not a Codex MRL for ginseng.
V. Conclusion
Therefore, tolerances are established for residues of zoxamide
(3,5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-4-
methylbenzamide) and its metabolites 3,5-dichloro-1,4-
benzenedicarboxylic acid (RH-1455 and RH-141455) and 3,5-dichloro-4-
hydroxymethylbenzoic acid (RH-1452 and RH-141452) calculated as the
[[Page 12015]]
stoichiometric equivalent of zoxamide in or on the raw agricultural
commodity ginseng at 0.30 ppm and vegetable, tuberous and corm,
subgroup 1C at 0.06 ppm. In addition, tolerances are established for
residues, determined by measuring only zoxamide (3,5-dichloro-N-(3-
chloro-1-ethyl-1-methyl-2-oxypropyl)-4-methylbenzamide, in or on raw
agricultural commodity tomato subgroup 8-10A at 2.0 ppm and fruit,
small vine climbing, except fuzzy kiwifruit, subgroup 13-07F at 5.0
ppm. Lastly, upon the establishment of the aforementioned tolerances,
the established tolerances for grape at 3.0 ppm; tomato at 2.0 ppm; and
potato at 0.060 ppm are removed as unnecessary.
VI. Statutory and Executive Order Reviews
This action 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 action has been
exempted from review under Executive Order 12866, this action 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 action 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 action 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 action. In addition, this
action does not impose any enforceable duty or contain any unfunded
mandate as described under Title II of the Unfunded Mandates Reform Act
(UMRA) (2 U.S.C. 1501 et seq.).
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 (NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.),
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
the rule in the Federal Register. This action is not a ``major rule''
as defined by 5 U.S.C. 804(2).
