II. Background and Statutory Findings
EPA on its own initiative, under section 408(e) of FFDCA, 21 U.S.C.
346a(e), is proposing to establish a tolerances for residues of the
insecticide chlorantraniliprole, 3-bromo-N-[4-chloro-2-methyl-6-
carboxamide, in or on cowpeas, forage and hay at 0.20 parts per million
(ppm); field peas, vines and hay at 0.20 ppm; forage, fodder and straw
of cereal grains, crop group 16 at 0.20 ppm, grass forage, fodder and
hay, crop group 17 at 0.20 ppm; leaves of root and tuber vegetables,
crop group 2 at 0.20 ppm; leeks at 0.20 ppm; nongrass animal feeds
(forage, fodder, straw and hay), crop group 18 at 0.20 ppm; okra at
0.70 ppm; onions, green at 0.20 ppm; onions,
Welsh at 0.20 ppm; peanuts, hay at 0.20 ppm; shallots at 0.20 ppm;
soybeans, forage and hay at 0.20 ppm; strawberries at 1.2 ppm; and
sugarcane, sugar at 0.20 ppm.
Recently, EPA established tolerances for chlorantraniliprole on
apple, wet pomace; brassica, head and stem, subgroup 5A; brassica,
leafy greens, subgroup 5B; cotton, gin byproduct; cotton, hulls; cotton
undelinted seed; fruit, pome, group 11; fruit, stone, group 12; grape;
grape, raisen; potato; vegetable, cucurbit, group 9; vegetable,
fruiting, group 8; vegetable, leafy, except brassica, group 4; milk;
meat; meat byproduct and fat. At that time EPA determined rotational
crop tolerances were required, and that the petitioner needed to
conduct extensive field rotational crop trials. The Agency concluded
that until the requested data are submitted, a restriction should be
imposed on labels prohibiting the rotation to any crop not on the
label. In response, the registrant submitted proposals for the
establishment of tolerances for inadvertent residues for a number of
crops pending submission of the requested data. After considering the
registrant's submission, EPA is now proposing time-limited tolerances
to address rotated crops.
EPA has decided to propose time-limited rotational crop tolerances
for chlorantraniliprole. Rotational crop trials (2003, 2004, 2005) were
conducted in Canada and the United States on leafy vegetables (Swiss
chard, lettuce, spinach), root vegetables (radish, beet, turnip),
cereal grains (wheat, oat) and soybean. Based on the data on
chlorantraniliprole, the Agency believes that the residue data would
not underestimate residues on rotated crops. Thus the Agency believes
that the 0.20 ppm tolerances on rotational crops are appropriate and
protective. EPA also determined that adding these proposed tolerances
would not change its prior safety finding for chlorantraniliprole.
EPA's updated risk assessment can be found at http://www.regulations.gov in docket ID number EPA-HQ-OPP-2008-0647.
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. . .
EPA performs a number of analyses to determine the risks from
aggregate exposure to pesticide residues. For further discussion of the
regulatory requirements of section 408 of the FFDCA and a complete
description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
III. Aggregate Risk Assessment and Determination of Safety
Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action. EPA has sufficient data to assess the hazards of and to
make a determination on aggregate exposure, consistent with section
408(b)(2) of FFDCA, for a tolerance for residues of
carboxamide, in or on cowpeas, forage and hay at 0.20 ppm; field peas,
vines and hay at 0.20 ppm; forage, fodder and straw of cereal grains,
crop group 16 at 0.20 ppm, grass forage, fodder and hay, crop group 17
at 0.20 ppm; leaves of root and tuber vegetables, crop group 2 at 0.20
ppm; leeks at 0.20 ppm; nongrass animal feeds (forage, fodder, straw
and hay), crop group 18 at 0.20 ppm; okra at 0.70 ppm; onions, green at
0.20 ppm; onions, Welsh at 0.20 ppm; peanuts, hay at 0.20 ppm; shallots
at 0.20 ppm; soybeans, forage and hay at 0.20 ppm; strawberries at 1.20
ppm; and sugarcane, sugar at 0.20 ppm. EPA's assessment of exposures
and risks associated with establishing the tolerance follows:
A. Toxicological Profile
EPA has evaluated the available toxicity data and considered its
validity, completeness, and reliability as well as the relationship of
the results of the studies to human risk. EPA has also considered
available information concerning the variability of the sensitivities
of major identifiable subgroups of consumers, including infants and
Chlorantraniliprole has no significant acute toxicity via the oral,
dermal, and inhalation routes of exposure. This substance is not an eye
or skin irritant and does not cause skin sensitization. In short-term
studies, the most consistent effects are those associated with non
adverse pharmacological response to the xenobiotic, induction of liver
enzymes and subsequent increase in liver weights. Chlorantraniliprole
is not genotoxic, neurotoxic, immunotoxic, carcinogenic, or
teratogenic. Furthermore, it is not uniquely toxic to the conceptus as
there were no maternal or fetal effects in studies conducted in rats
and rabbits. Based on the results of a 28-day dermal study in rats, as
well as the dermal LD50 study, chlorantraniliprole has
relatively low dermal toxicity.
Overall, chlorantraniliprole exhibits minimal mammalian toxicity
after long-term exposure. The only consistent observation in the
mammalian toxicology studies is an increased degree of
microvesiculation of the adrenal cortex after dermal or dietary
administration of chlorantraniliprole. Based on the lack of adverse
effect on the function of the adrenal gland, this observation was
considered treatment related, but not ``adverse.''In addition to the
adrenal effects, liver effects (e.g., increased liver weight and
induction of cytochrome P450 enzymes) were reported in the 90-day oral
subchronic studies across species and only at the highest dose tested
(HDT) >1,000 milligram/kilogram/day (mg/kg/day). While in the
subchronic studies, these effects were considered adaptive, the liver
effects were more pronounced in the 18-month chronic mouse study at the
HDT. Increased eosinophilic foci (preneoplastic foci) were noted in
male mice at 935 mg/kg/day and liver hypertrophy and weight increase
were evident at the next lower dose (158 mg/kg/day), but progression to
tumors was not apparent for these effects. Therefore, the eosinophilic
foci appear to be an adverse effect only seen in the HDT and was graded
minimal in severity.
Specific information on the studies received and the nature of the
toxic effects caused by chlorantraniliprole 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 http://www.regulations.gov. The referenced document is available in the docket
established by this action, which is described under ADDRESSES, and is
identified as EPA-HQ-OPP-2007-0275 in that docket.
B. Toxicological Endpoints
For hazards that have a threshold below which there is no
risk, the toxicological level of concern (LOC) is derived from the
highest dose at which no adverse effects are observed (the NOAEL) in
the toxicology study identified as appropriate for use in risk
assessment. However, if a NOAEL cannot be determined, the lowest dose
at which adverse effects of concern are identified (the LOAEL) is
sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the LOC to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
risks by comparing aggregate exposure to the pesticide to the acute
population adjusted dose (aPAD) and chronic population adjusted dose
(cPAD). The aPAD and cPAD are calculated by dividing the LOC by all
applicable UFs. Short-term, intermediate-term, and long-term risks are
evaluated by comparing aggregate exposure to the LOC to ensure that the
margin of exposure (MOE) called for by the product of all applicable
UFs is not exceeded.
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk and estimates risk in terms
of the probability of occurrence of additional adverse cases.
Generally, cancer risks are considered non-threshold. For more
information on the general principles EPA uses in risk characterization
and a complete description of the risk assessment process, see http://www.epa.gov/fedrgstr/EPA-PEST/1997/November/Day-26/p30948.htm.
A summary of the toxicological endpoints for chlorantraniliprole
used for human risk assessment can be found at http://www.regulations.gov in document Chlorantraniliprole (DPX-E2Y45): Human
Health Risk Assessment for Proposed Uses on pome fruit, stone fruit,
leafy vegetables, brassica leafy vegetables, cucurbit vegetables,
fruiting vegetables, cotton, grapes, potatoes, rice, turf and
ornamentals pages 22-24 in docket ID number EPA-HQ-OPP-2007-0275.
C. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to chlorantraniliprole, EPA considered exposure under the
petitioned-for tolerances as well as all existing chlorantraniliprole
tolerances in (40 CFR 180.628). EPA assessed dietary exposures from
chlorantraniliprole 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 chlorantraniliprole;
therefore, a quantitative acute dietary exposure assessment is
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the United States
Department of Agriculture (USDA) 1994-1996 and 1998 CSFII. As to
residue levels in food, EPA assumed all foods for which there are
tolerances were treated and contain tolerance-level residues.
The inclusion of additional livestock feeds such as forage, fodder
and straw from cowpea, field pea, soybean, cereal grains, nongrass
animal feeds or peanut does not increase the livestock dietary burdens
and thus the meat and milk tolerances. While the addition of
strawberries, sugarcane, leek, onions, shallot, and okra that are
considered human food results in a miniscule increase in exposure, a
DEEM analysis that incorporates all the new commodities does not change
the risk outcome which remains at 1% of the cPAD for the most highly
exposed population, children ages 1-2. In addition, the dietary
exposure from leeks, onions and shallots is negligible.
iii. Cancer. Because chlorantraniliprole has been classified as a
``not likely human carcinogen'', a quantitative exposure assessment
relative to cancer risk is not necessary.
2. Dietary exposure from drinking water. The Agency lacks
sufficient monitoring data to complete a comprehensive dietary exposure
analysis and risk assessment for chlorantraniliprole in drinking water.
Because the Agency does not have comprehensive monitoring data,
drinking water concentration estimates are made by reliance on
simulation or modeling taking into account data on the environmental
fate characteristics of chlorantraniliprole. Further information
regarding EPA drinking water models used in pesticide exposure
assessment can be found at http://www.epa.gov/oppefed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated environmental concentrations (EECs) of
chlorantraniliprole for acute exposures are estimated to be 26.862
parts per billion (ppb) for surface water and 1.06 ppb for ground
water. The EECs for chronic exposures are estimated to be 3.650 ppb for
surface water and 1.06 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. Because no acute hazard,
attributable to a single dose, was identified; acute dietary risk was
not assessed. For chronic dietary risk assessment, the water
concentration value 3.650 ppb was used to access the contribution to
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).
Chlorantraniliprole is registered for use on the following
residential non-dietary sites: Turfgrass and ornamental plants.
Although residential exposure could occur, due to the lack of toxicity
identified for short-term and intermediate-term durations via the
relevant routes of exposure, no risk is expected from these exposures.
Additional information on residential exposure assumptions can be
found at www.regulations.gov (Docket ID EPA-HQ-OPP-2007-0275, pages 36
4. Cumulative effects from substances with a common mechanism of
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when
considering whether to establish, modify, or revoke a tolerance, the
Agency consider ``available information'' concerning the cumulative
effects of a particular pesticide's residues and ``other substances
that have a common mechanism of toxicity.''
Unlike other pesticides for which EPA has followed a cumulative
risk approach based on a common mechanism of toxicity, EPA has not made
a common mechanism of toxicity finding as to chlorantraniliprole and
any other substances and chlorantraniliprole does not appear to produce
a toxic metabolite produced by other substances. For the purposes of
this tolerance action, therefore, EPA has not assumed that
chlorantraniliprole has a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see the policy statements
released by EPA's Office of Pesticide Programs concerning common
mechanism determinations and procedures for cumulating effects from
found to have a common mechanism on EPA's website at http://www.epa.gov/pesticides/cumulative.
D. Safety Factor for Infants and Children
1. In general. Section 408 of FFDCA provides that EPA shall apply
an additional (10X) tenfold margin of safety for infants and children
in the case of threshold effects to account for prenatal and postnatal
toxicity and the completeness of the database on toxicity and exposure
unless EPA determines based on reliable data that a different margin of
safety will be safe for infants and children. This additional margin of
safety is commonly referred to as the FQPA safety factor. In applying
this provision, EPA either retains the default value of 10X when
reliable data do not support the choice of a different factor, or, if
reliable data are available, EPA uses a different additional FQPA
safety factor value based on the use of traditional UFs and/or special
FQPA safety factors, as appropriate.
2. Prenatal and postnatal sensitivity. There were no effects on
fetal growth or postnatal development up to the limit dose of 1,000 mg/
kg/day in rats or rabbits in the developmental or 2-generation
reproduction studies. Additionally, there were no treatment related
effects on the numbers of litters, fetuses (live or dead), resorptions,
sex ratio, or post-implantation loss and no effects on fetal body
weights, skeletal ossification, and external, visceral, or skeletal
malformations or variations.
3. Conclusion. EPA has determined that reliable data show that it
would be safe for infants and children to reduce the FQPA safety factor
to 1X. That decision is based on the following findings:
i. The toxicology database for chlorantraniliprole is complete for
the purposes of this risk assessment and the characterization of
potential prenatal and postnatal risks to infants and children.
ii. No susceptibility was identified in the toxicological database,
and there are no residual uncertainties re: prenatal and/or postnatal
iii. There are no treatment-related neurotoxic findings in the
acute and subchronic oral neurotoxicity studies in rats.
iv. The exposure assessment is protective: The dietary food
exposure assessment utilizes tolerance level residues and 100 percent
crop treated (PCT) information for all commodities. The submitted field
rotational crop studies do not match those recommended in the
guidelines. However, data from confined rotational crop studies and
field rotational crop studies show that uptake of chlorantraniliprole
is below the quantification level in roots and grains, and range of
0.01 to 0.15 ppm in tops of root vegetables and forage, fodder and
straw of cereal grains and soybean. The 0.20 ppm tolerances based on
the collective data should be conservative. Also, the tolerances on
rotational crops strawberry and okra are conservative since the
strawberry tolerance is based on residues in grape from direct
application of chlorantraniliprole and the okra tolerance is based on
residues resulting from direct treatment on tomato and pepper. An
exposure assessment using conservative residue values is expected to be
The drinking water assessment utilizes values generated by models
and associated modeling parameters which are designed to provide
conservative, health protective, high-end estimates of water
concentrations. By using these screening-level exposure assessments,
the chronic dietary (food and drinking water) risk is not
v. Although residential exposure is expected over the short- and
possibly intermediate-term (via the dermal and/or incidental oral
route), there is no hazard expected via these routes/durations, and
therefore no risk for these scenarios.
E. Aggregate Risks and Determination of Safety
Safety is assessed for acute and chronic risks by comparing
aggregate exposure to the pesticide to the aPAD and cPAD. The aPAD and
cPAD are calculated by dividing the LOC by all applicable UFs. For
linear cancer risks, EPA calculates the probability of additional
cancer cases given aggregate exposure. Short-term, intermediate-term,
and long-term risks are evaluated by comparing aggregate exposure to
the LOC to ensure that the MOE called for by the product of all
applicable UFs is not exceeded.
1. Acute risk. No acute risk is expected because no acute hazard,
attributable to a single dose, was identified.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that exposure to
chlorantraniliprole from food and water will utilize <1% of the cPAD
for the population group children 1-2 years (the highest exposed
subpopulation). Based the use pattern, chronic residential exposure to
residues of chlorantraniliprole is not expected.
3. Short-term/intermediate risk. Short-term aggregate and
intermediate-term exposure takes into account residential exposure plus
chronic exposure to food and water (considered to be a background
There is potential for short-term and intermediate-term post-
application dermal (adults and children) and incidental oral (children
only) exposure to chlorantraniliprole. However, due to the lack of
toxicity via dermal route, as well as the lack of toxicity over the
acute, short-term and intermediate-term via the oral route - no risk is
expected from these exposures. Inhalation exposure is not expected due
to the low vapor pressure of chlorantraniliprole (so applied/deposited
residues are not expected to volatilize into the air).
4. Aggregate cancer risk for U.S. population. Chlorantraniliprole
has been classified as a ``not likely human carcinogen.'' It 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 chlorantraniliprole residues.
IV. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology liquid chromatography/mass
spectrometry (LC/MS) is available to enforce the tolerance expression.
The methods may be requested from: Chief, Analytical Chemistry Branch,
Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350;
telephone number: (410) 305-2905; e-mail address:
B. International Residue Limits
There are no international residue limits that affect the Agency's
recommendations at this time. There are no CODEX or Mexican maximum
residue limits (MRLs) for chlorantraniliprole that exists at this time.
Tolerances may be made permanent following submission of rotational
crop residue data suitable for establishing tolerances.
Time-limited tolerances are proposed for residues of
carboxamide, in or on cowpea, forage and hay at 0.20 ppm; field pea,
vines and hay at 0.20 ppm; forage, fodder and straw of cereal grains,
crop group 16 at 0.20 ppm, grass forage, fodder and hay,
crop group 17 at 0.20 ppm; leaves of root and tuber vegetables, crop
group 2 at 0.20 ppm; leek at 0.20 ppm; nongrass animal feeds (forage,
fodder, straw and hay), crop group 18 at 0.20 ppm; okra at 0.70 ppm;
onion, green at 0.20 ppm; onion, Welsh at 0.20 ppm; peanut, hay at 0.20
ppm; shallot at 0.20 ppm; soybean, forage and hay at 0.20 ppm;
strawberries at 1.20 ppm; and sugarcane, sugar at 0.20 ppm.
VI. Statutory and Executive Order Reviews
This proposed rule establishes a tolerance under section 408(d) of
FFDCA 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 proposed rule has
been exempted from review under Executive Order 12866 due to its lack
of significance, this proposed 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).
This proposed rule does not contain any information collections subject
to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501
et seq., or impose any enforceable duty or contain any unfunded mandate
as described under Title II of the Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104-4). 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); or OMB review or any
Agency action under Executive Order 13045, entitled Protection of
Children from Environmental Health Risks and Safety Risks (62 FR 19885,
April 23, 1997). 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). The Agency hereby certifies, under the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et seq.), that this proposed action
will not have significant negative economic impact on a substantial
number of small entities. A tolerance is one of the regulatory
requirements needed for use of a pesticide and thus establishing a
tolerance is expected to have no adverse economic impact. In addition,
the Agency has determined that this action will not have a substantial
direct effect on States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government, as specified
in Executive Order 13132, entitled Federalism (64 FR 43255, August 10,
1999). Executive Order 13132 requires EPA to develop an accountable
process to ensure ``meaningful and timely input by State and local
officials in the development of regulatory policies that have
federalism implications.'' ``Policies that have federalism
implications'' is defined in the Executive order to include regulations
that have ``substantial direct effects on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government.'' This proposed rule directly regulates growers, food
processors, food handlers, and food retailers, not States. This action
does not alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency
has determined that this proposed rule does not have any ``tribal
implications'' as described in Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000). Executive Order 3175, requires EPA to develop
an accountable process to ensure ``meaningful and timely input by
tribal officials in the development of regulatory policies that have
tribal implications.'' ``Policies that have tribal implications'' is
defined in the Executive order to include regulations that have
``substantial direct effects on one or more Indian tribes, on the
relationship between the Federal Government and the Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes.'' This proposed rule will not have
substantial direct effects on tribal governments, on the relationship
between the Federal Government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this proposed rule.
