Dow AgroSciences
PP 3F6794
EPA has received a pesticide petition 3F6794 from Dow AgroSciences,
9330 Zionsville Road, Indianapolis, IN 46268 proposing, pursuant to
section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part
180 by establishing a tolerance for residues of methoxyfenozide in or
on the raw agricultural commodity soybean, seed at 2 parts per million
(ppm), soybean, forage at 45 ppm, soybean, hay at 65 ppm, soybean,
aspirated grain fractions at 200 ppm, soybean, hulls at 3 ppm, soybean,
meal at 0.1 ppm, soybean, oil at 1.0 ppm. EPA has determined that the
petition contains data or information regarding the elements set forth
in section 408(d)(2) of the FFDCA; however, EPA has not fully evaluated
the sufficiency of the submitted data at this time or whether the data
support granting of the petition. Additional data may be needed before
EPA rules on the petition.
A. Residue Chemistry
1. Plant metabolism. The qualitative nature of methoxyfenozide
residues in plants and animals is adequately understood and was
previously published in the Federal Register of July 5, 2000 (65 FR
41355) (FRL-6497-5).
2. Analytical method. Adequate enforcement methods are available
for determination of methoxyfenozide residues in plant commodities. The
available Analytical Enforcement Methodology was previously reviewed in
the Federal Register of September 20, 2002 (67 FR 59193) (FRL-7198-5).
3. Magnitude of residues. Complete residue data for methoxyfenozide
on soybeans has been submitted. The requested tolerances are adequately
supported.
B. Toxicological Profile
The toxicological profile and endpoints for methoxyfenozide which
supports this petition to establish tolerances were previously
published in the Federal Register of September 20, 2002 (67 FR 59193).
C. Aggregate Exposure
1. Dietary exposure. Assessments were conducted to evaluate
potential risks due to chronic and acute dietary exposure of the U.S.
population subgroups to residues of methoxyfenozide. These analyses
cover all registered crops, as well as, uses pending with the Agency,
active and proposed section 18 uses, and proposed IR-4 minor uses.
There are no registered residential nonfood uses of methoxyfenozide.
i. Food--a. Acute risk. No appropriate toxicological endpoint
attributable to a single exposure was identified in the available
toxicology studies on methoxyfenozide including the acute neurotoxicity
study in rats, the developmental toxicity study in rats and the
developmental toxicity study in rabbits. Since no acute toxicological
endpoints were established, Dow AgroSciences considers acute aggregate
risk to be negligible.
b. Chronic. Assessments were conducted to evaluate potential risks
due to chronic dietary exposure of the U.S. population and selected
population subgroups to residues of methoxyfenozide. These analyses
cover all registered crops, uses pending with the EPA, active and
proposed section 18 uses and new proposed IR-4 uses. Dow AgroSciences
used the Dietary Exposure Evaluation Model (DEEM), Novigen Sciences,
Washington, DC software for conducting a chronic dietary (food) risk
analysis. DEEM is a dietary exposure analysis system that is used to
estimate exposure to a pesticide chemical in foods comprising the diets
of the U.S. population, including population subgroups. DEEM contains
food consumption data as reported by respondents in the United States
Department of Agriculture (USDA) Continuing Surveys of Food Intake by
Individuals conducted in 1994 to 1998. Dow AgroSciences assumed 100% of
crops would be treated and contain methoxyfenozide residues at the
tolerance level. The resulting dietary exposure analysis is summarized
in Table 1.
The resulting dietary food exposures occupy up to 49.4% of the
chronic population adjusted dose (PAD) for the most highly exposed
population subgroup, children 1 to 2 years old. These results should be
viewed as conservative (health protective) risk estimates. Refinements
such as use of percent crop-treated information and/or anticipated
residue values would yield even lower estimates of chronic dietary
exposure.

ii. Drinking water. There are no water-related exposure data from
monitoring to complete a quantitative drinking water exposure analysis
and risk assessment for methoxyfenozide. Generic Expected Environmental
Concentration (GENEEC) and/or EPA's Pesticide Root Zone Model/Exposure
Analysis Modeling System (PRZM/EXAMS) (both produce estimates of
pesticide concentration in a farm pond) are used to generate estimated
environmental concentrations (EECs) for surface water and Screening
Concentration in Ground Water (SCI-GROW) (an empirical model based upon
actual monitoring data collected for a number of pesticides that serve
as benchmarks) predicts EECs in ground water. These models take into
account the use patterns and the environmental profile of a pesticide,
but do not include consideration of the impact that processing raw
water for distribution as drinking water would likely have on the
removal of pesticides from the source water. The primary use of these
models at this stage is to provide a coarse screen for assessing
whether a pesticide is likely to be present in drinking water at
concentrations which would exceed human health levels of concern.
A drinking water level of comparison (DWLOC) is the concentration
of a pesticide in drinking water that would be acceptable as a
theoretical upper limit in light of total aggregate exposure to that
pesticide from food, water, and residential uses. EPA's Health Effects
Division (HED) uses DWLOCs internally in the risk assessment process as
a surrogate measure of potential exposure associated with pesticide
exposure through drinking water. In the absence of monitoring data for
a pesticide, the DWLOC is used as a point of comparison against the
conservative EECs provided by computer modeling (SCI-GROW, GENEEC,
PRZM/EXAMS).
a. Acute exposure and risk. Because no acute dietary endpoint was
determined, Dow AgroSciences concludes that there is a reasonable
certainty of no harm from acute exposure from drinking water.
b. Chronic exposure and risk. Tier II screening-level assessments
can be conducted using the simulation models SCI-GROW and PRZM/EXAMS to
generate EECs for ground water and surface water, respectively. The
modeling was conducted based on the environmental profile and the
maximum seasonal application rate proposed for methoxyfenozide (1.0 lb
active ingredient (a.i.)/acre/season). PRZM/EXAMS was used to generate
the surface water EECs, because it can factor the persistent nature of
the chemical into the estimates.
The EECs for assessing chronic aggregate dietary risk used by HED
are 3.5 parts per billion (ppb) (in ground water, based on SCI-GROW)
and 30 ppb (in surface water, based on the PRZM/EXAMS, long-term mean).
The back-calculated DWLOCs for assessing chronic aggregate dietary risk
range from 516 ppb for the most highly exposed population subgroup
(children 1 to 2 years old) to 2,798 ppb for the U.S. population
(total).
The SCI-GROW and PRZM/EXAMS chronic EECs are less than the Agency's
level of comparison (the DWLOC value for each population subgroup) for
methoxyfenozide residues in drinking water as a contribution to chronic
aggregate exposure. Dow AgroSciences thus concludes with reasonable
certainty that residues of methoxyfenozide in drinking water will not
contribute significantly to the aggregate chronic human health risk and
that the chronic aggregate exposure from methoxyfenozide residues in
food and drinking water will not exceed the Agency's level of concern
(100% of the chronic PAD) for chronic dietary aggregate exposure by any
population subgroup. EPA generally has no concern for exposures below
100% of the chronic PAD, because it is a level at or below which daily
aggregate dietary exposure over a lifetime will not pose appreciable
risks to the health and safety of any population subgroup. This risk
assessment is considered high confidence, conservative, and very
protective of human health.

2. Non-dietary exposure. Methoxyfenozide is not currently
registered for use on any residential non-food sites. Therefore, there
is no non-dietary acute, chronic, short-term or intermediate-term
exposure.
D. Cumulative Effects
Section 408(b)(2)(D)(v) 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 does not have, at this time, available data to determine
whether methoxyfenozide has a common mechanism of toxicity with other
substances or how to include this pesticide in a cumulative risk
assessment. Unlike other pesticides for which EPA has followed a
cumulative risk approach based on a common mechanism of toxicity,
methoxyfenozide does not appear to produce a toxic metabolite produced
by other substances. For the purposes of this tolerance action,
therefore, it is assumed that methoxyfenozide does not have a common
mechanism of toxicity with other substances.
E. Safety Determination
1. U.S. population. Using the DEEM exposure assumptions described
in this unit, Dow AgroSciences has concluded that aggregate exposure to
methoxyfenozide from the proposed new tolerances will utilize 21.6% of
the chronic PAD for the U.S. population. The major identifiable
subgroup with the highest aggregate exposure is children 1 to 2 years
old at 49.4% of the chronic PAD and is discussed below. EPA generally
has no concern for exposures below 100% of the chronic PAD because the
chronic PAD represents the level at or below which daily aggregate
dietary exposure over a lifetime will not pose appreciable risks to
human health. Despite the potential for exposure to methoxyfenozide in
drinking water, the aggregate exposure is not expected to exceed 100%
of the chronic PAD. Dow AgroSciences concludes that there is a
reasonable certainty that no harm will result from aggregate exposure
to methoxyfenozide residues.
2. Infants and children. In assessing the potential for additional
sensitivity of infants and children to residues of methoxyfenozide, EPA
considered data from developmental toxicity studies in the rat and
rabbit and a 2-generation reproduction study in the rat. The
developmental toxicity studies are designed to evaluate adverse effects
on the developing organism resulting from maternal pesticide exposure
during gestation. Reproduction studies provide information relating to
effects from exposure to the pesticide on the reproductive capability
of mating animals and data on systemic toxicity.
FFDCA section 408 provides that EPA shall apply an additional ten-
fold 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 data base unless EPA determines that a different
margin of safety will be safe for infants and children. Margins of
safety are incorporated into EPA risk assessments either directly
through use of a margin of exposure (MOE) analysis or through using
uncertainty (safety) factors in calculating a dose level that poses no
appreciable risk to humans. EPA believes that reliable data support
using the standard uncertainty factor (UF) (usually 100 for combine
interspecies and intraspecies variability) and not the additional ten-
fold MOE/UF when EPA has a complete data base under existing guidelines
and when the severity of the effect in infants or children or the
potency or unusual toxic properties of a compound do not raise concerns
regarding the adequacy of the standard MOE/safety factor.
The toxicology data base for methoxyfenozide included acceptable
developmental toxicity studies in both rats and rabbits as well as a 2-
generation reproductive toxicity study in rats. The data provided no
indication of increased sensitivity of rats or rabbits to in utero and/
or postnatal exposure to methoxyfenozide. There is a complete toxicity
data base for methoxyfenozide and exposure data are complete or are
estimated based on data that reasonably accounts for potential
exposures. Based on the completeness of the data base and the lack of
prenatal and postnatal toxicity, EPA determined that an additional
safety factor was not needed for the protection of infants and
children.
Since no toxicological endpoints were established, acute aggregate
risk is considered to be negligible. Using the exposure assumptions
described in this unit, Dow AgroSciences has concluded that aggregate
exposure to methoxyfenozide from the proposed new tolerances will
utilize 49.4% of the cPAD for infants and children. EPA generally has
no concern for exposures below 100% of the cPAD because the cPAD
represents the level at or below which daily aggregate dietary exposure
over a lifetime will not pose appreciable risks to human health.
Despite the potential for exposure to methoxyfenozide in drinking
water, Dow AgroSciences does not expect the aggregate exposure to
exceed 100% of the cPAD. Short and intermediate term risks are judged
to be negligible due to the lack of significant toxicological effects
observed. Based on these risk assessments, Dow AgroSciences concludes
that there is a reasonable certainty that no harm will result to
infants and children from aggregate exposure to methoxyfenozide
residues.
F. International Tolerances
There are no Codex or Canadian maximum residue levels (MRLs)
established for residues of methoxyfenozide. Mexican MRLs are
established for residues of methoxyfenozide in cottonseed (0.05 ppm)
and maize (0.01 ppm). The U.S. tolerances on these commodities are 2.0
ppm and 0.05 ppm, respectively. Based on the current use patterns, the
U.S. tolerance levels cannot be reduced to harmonize with the Mexican
MRLs, so incompatibility will exist.
