Federal Register / Vol. 73, No. 173 / Friday, September 5, 2008 / Rules and Regulations
Populations (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established in accordance with
sections 408(e) and 408(l)(6) of FFDCA,
such as the tolerances in this final rule,
do not require the issuance of a
proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).

II. Background and Statutory Findings
EPA, on its own initiative, in
accordance with sections 408(e) and
408(l)(6) of FFDCA, 21 U.S.C. 346a(e)
and 346a(1)(6), is establishing timelimited tolerances for residues of the
insecticide chlorantraniliprole, 3bromo-N-[4-chloro-2-methyl-6[(methylamino)carbonyl]phenyl]-1-(3chloro-2-pyridinyl)-1H-pyrazole-5carboxamide), in or on corn, sweet,
kernel plus cob with husks removed at
0.01 parts per million (ppm); corn,
sweet, forage at 6.0 ppm; corn, sweet,
stover at 6.0 ppm; corn, sweet, cannery
waste at 6.0 ppm; and milk at 0.03 ppm.
These time-limited tolerances expire
and are revoked on December 31, 2011.
EPA will publish a document in the
Federal Register to remove the revoked
tolerances from the CFR.
Section 408(l)(6) of FFDCA requires
EPA to establish a time-limited
tolerance or exemption from the
requirement for a tolerance for pesticide
chemical residues in food that will
result from the use of a pesticide under
an emergency exemption granted by
EPA under section 18 of FIFRA. Such
tolerances can be established without
providing notice or period for public
comment. EPA does not intend for its
actions on section 18 related timelimited tolerances to set binding
precedents for the application of section
408 of FFDCA and the new safety
standard to other tolerances and
exemptions. Section 408(e) of FFDCA
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
allows EPA to establish a tolerance or an
exemption from the requirement of a
tolerance on its own initiative, i.e.,
without having received any petition
from an outside party.
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. . . .’’
Section 18 of FIFRA authorizes EPA
to exempt any Federal or State agency
from any provision of FIFRA, if EPA
determines that ‘‘emergency conditions
exist which require such exemption.’’
EPA has established regulations
governing such emergency exemptions
in 40 CFR part 166.
III. Emergency Exemption for
Chlorantraniliprole on Sweet Corn and
FFDCA Tolerances
The states of Illinois and Minnesota
requested the use of chlorantraniliprole,
formulated as the product Coragen (EPA
Reg. No. 352–729), on sweet corn to
control corn earworms. According to
these states, the available registered
alternatives were not providing
adequate control of this pest and
without the use of Coragen, growers
would suffer significant economic
losses. After having reviewed the
submission, EPA determined that
emergency conditions exist for these
States, and that the criteria for an
emergency exemption are met. EPA has
authorized under FIFRA section 18 the
use of chlorantraniliprole on sweet corn
for control of corn earworm in Illinois
and Minnesota.
As part of its evaluation of the
emergency exemption applications, EPA
assessed the potential risks presented by
residues of chlorantraniliprole in or on
sweet corn and various associated sweet
corn-related commodities. In doing so,
EPA considered the safety standard in
section 408(b)(2) of FFDCA, and EPA
E:\FR\FM\05SER1.SGM
05SER1
Federal Register / Vol. 73, No. 173 / Friday, September 5, 2008 / Rules and Regulations
hsrobinson on PROD1PC76 with RULES
decided that the necessary tolerances
under section 408(l)(6) of FFDCA would
be consistent with the safety standard
and with FIFRA section 18. Consistent
with the need to move quickly on the
emergency exemption in order to
address an urgent non-routine situation
and to ensure that the resulting food is
safe and lawful, EPA is issuing these
tolerances without notice and
opportunity for public comment as
provided in section 408(l)(6) of FFDCA.
Although these time-limited tolerances
expire and are revoked on December 31,
2011, under section 408(l)(5) of FFDCA,
residues of the pesticide not in excess
of the amounts specified in the
tolerance remaining in or on these
commodities after that date will not be
unlawful, provided the pesticide was
applied in a manner that was lawful
under FIFRA, and the residues do not
exceed a level that was authorized by
these time-limited tolerances at the time
of that application. EPA will take action
to revoke these time-limited tolerances
earlier if any experience with, scientific
data on, or other relevant information
on this pesticide indicate that the
residues are not safe.
Because these time-limited tolerances
are being approved under emergency
conditions, EPA has not made any
decisions about whether
chlorantraniliprole meets FIFRA’s
registration requirements for use on
sweet corn or whether permanent
tolerances for this use would be
appropriate. Under these circumstances,
EPA does not believe that these timelimited tolerance decisions serve as a
basis for registration of
chlorantraniliprole by a State for special
local needs under FIFRA section 24(c).
Nor do these tolerances serve as the
basis for persons in any State other than
Illinois and Minnesota to use this
pesticide on this crop under FIFRA
section 18 absent the issuance of an
emergency exemption applicable within
that State. For additional information
regarding the emergency exemption for
chlorantraniliprole, contact the
Agency’s Registration Division at the
address provided under FOR FURTHER
INFORMATION CONTACT.
IV. 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
VerDate Aug<31>2005
19:20 Sep 04, 2008
Jkt 214001
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 the factors specified
in section 408(b)(2)(D) of FFDCA, EPA
has reviewed the available scientific
data and other relevant information in
support of this action. EPA has
sufficient data to assess the hazards of
and to make a determination on
aggregate exposure expected as a result
of these emergency exemption requests
and the time-limited tolerances for
residues of chlorantraniliprole on corn,
sweet, kernel plus cob with husks
removed at 0.01 ppm; corn, sweet,
forage at 6.0 ppm; corn, sweet, stover at
6.0 ppm; corn, sweet, cannery waste at
6.0 ppm; and milk at 0.03 ppm. EPA’s
assessment of exposures and risks
associated with establishing these timelimited tolerances follows.
A. Toxicological Endpoints
For hazards that have a threshold
below which there is no appreciable
risk, a toxicological point of departure
(POD) is identified as the basis for
derivation of reference values for risk
assessment. The POD may be defined as
the highest dose at which no adverse
effects are observed (the NOAEL) in the
toxicology study identified as
appropriate for use in risk assessment.
However, if a NOAEL cannot be
determined, the lowest dose at which
adverse effects of concern are identified
(the LOAEL) or a Benchmark Dose
(BMD) approach is sometimes used for
risk assessment. Uncertainty/safety
factors (UFs) are used in conjunction
with the POD to take into account
uncertainties inherent in the
extrapolation from laboratory animal
data to humans and in the variations in
sensitivity among members of the
human population as well as other
unknowns. Safety is assessed for acute
and chronic dietary risks by comparing
aggregate food and water exposure to
the pesticide to the acute population
adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The
aPAD and cPAD are calculated by
dividing the POD by all applicable UFs.
Aggregate short-, intermediate-, and
chronic-term risks are evaluated by
PO 00000
Frm 00013
Fmt 4700
Sfmt 4700
51729
comparing food, water, and residential
exposure to the POD to ensure that the
margin of exposure (MOE) called for by
the product of all applicable UFs is not
exceeded. This latter value is referred to
as the Level of Concern (LOC).
For non-threshold risks, the Agency
assumes that any amount of exposure
will lead to some degree of risk. Thus,
the Agency estimates risk in terms of the
probability of an occurrence of the
adverse effect greater than that expected
in a lifetime. For more information on
the general principles EPA uses in risk
characterization and a complete
description of the risk assessment
process, see https://www.epa.gov/
pesticides/factsheets/riskassess.htm.

2007–0275.
B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to chlorantraniliprole, EPA
considered exposure under the timelimited tolerance established by this
action 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. No acute effects
were identified in the dietary
toxicological studies for
chlorantraniliprole; 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. EPA’s chronic dietary exposure
estimates for chlorantriliprole are based
on tolerance level residues, assuming
100% crops associated with the existing
uses and section 18 requests are treated,
and included the highest modeled
estimated drinking water concentration
relevant to the scenario.
iii. Cancer. Chlorantraniliprole is
classified as ‘‘Not likely to be
Carcinogenic to Humans,’’ and therefore
a cancer exposure assessment is
unnecessary.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue and/or PCT
E:\FR\FM\05SER1.SGM
05SER1
hsrobinson on PROD1PC76 with RULES
51730
Federal Register / Vol. 73, No. 173 / Friday, September 5, 2008 / Rules and Regulations
information in the dietary assessment
for chlorantraniliprole. 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 chlorantraniliprole in drinking
water. These simulation models take
into account data on the physical,
chemical, and fate/transport
characteristics of chlorantraniliprole.
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 Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening
Concentration in Ground Water (SCIGROW) models, the estimated drinking
water concentrations (EDWCs) of
chlorantraniliprole for chronic
exposures for non-cancer assessments
are estimated to be 3.65 parts per billion
(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. For
chronic dietary risk assessment, the
water concentration of value 3.65 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).
Chlorantraniliprole is currently
registered for the following uses that
could result in residential exposures:
Turfgrass and ornamental plants. EPA
assessed residential exposure using the
following assumptions: Inhalation
exposure is not expected due to low
vapor pressure; dermal postapplication
exposure is possible for adults and
children for short- and intermediateterm durations, and exposure from
incidental oral ingestion is possible for
children.
However, due to the lack of toxicity
via the dermal route, as well as the lack
of toxicity over the acute, short- and
intermediate- term via the oral route, no
risk is expected from these exposures.
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
VerDate Aug<31>2005
19:20 Sep 04, 2008
Jkt 214001
pesticide’s residues and ‘‘other
substances that have 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 substances
found to have a common mechanism on
EPA’s website at https://www.epa.gov/
pesticides/cumulative.
C. 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
FQPA safety factor (SF). In applying this
provision, EPA either retains the default
value of 10X, or uses a different
additional SF when reliable data
available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity.
Chlorantraniliprole did not result in
developmental toxicity in either rats or
rabbits or in reproductive effects in the
multi–generation reproduction study.
There was no indication of increased
offspring susceptibility in these studies.
3. Conclusion. EPA has determined
that reliable data show that 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
chlorantraniliprole is complete.
ii. There is no indication that
chlorantraniliprole 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
chlorantraniliprole results in increased
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
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
chlorantraniliprole in drinking water.
EPA used similarly conservative
assumptions to assess postapplication
exposure of children as well as
incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by chlorantraniliprole.
D. Aggregate Risks and Determination of
Safety
EPA determines whether acute and
chronic pesticide exposures are safe by
comparing aggregate exposure estimates
to the aPAD and cPAD. The aPAD and
cPAD represent the highest safe
exposures, taking into account all
appropriate SFs. EPA calculates the
aPAD and cPAD by dividing the POD by
all applicable UFs. For linear cancer
risks, EPA calculates the probability of
additional cancer cases given the
estimated aggregate exposure. Short-,
intermediate-, and chronic-term risks
are evaluated by comparing the
estimated aggregate food, water, and
residential exposure to the POD to
ensure that the MOE called for by the
product of all applicable UFs is not
exceeded.
1. Acute risk. An acute aggregate risk
assessment takes into account exposure
estimates from acute dietary
consumption of food and drinking
water. No adverse effect resulting from
a single-oral exposure was identified,
therefore, chlorantraniliprole 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
chlorantraniliprole from food and water
will utilize 1% of the cPAD for
(children 1-2 years old) the population
group receiving the greatest exposure.
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).
Although short-term residential
exposure could occur with the use of
chlorantraniliprole, no toxicological
effects resulting from short-term dosing
were observed. Therefore, the aggregate
E:\FR\FM\05SER1.SGM
05SER1
51731
Federal Register / Vol. 73, No. 173 / Friday, September 5, 2008 / Rules and Regulations
short-term risk is the sum of the risk
from 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
non-dietary, non-occupational exposure
plus chronic exposure to food and water
(considered to be a background
exposure level).
Although intermediate-term
residential exposure could result from
the use of chlorantraniliprole, no
toxicological effects resulting from
intermediate-term dosing were
observed. Therefore, the aggregate
intermediate-term risk is the sum of the
risk from food and water and will not
be greater than the chronic aggregate
risk.
5. Aggregate cancer risk for U.S.
population. Chlorantraniliprole is
classified as ‘‘Not likely to be
Carcinogenic to Humans’’ and is
therefore not expect to pose a cancer
risk.
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
chlorantraniliprole residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology
(LC/MS/MS) is available to enforce the
tolerance expression. The method may
be requested from: Chief, Analytical
Chemistry Branch, Environmental
Science Center, 701 Mapes Rd., Ft.
Meade, MD 20755–5350; telephone
number: (410) 305–2905; e-mail address:

B. International Residue Limits
There are no CODEX residue limits
for residues of chlorantraniliprole on
sweet corn commodities or in milk.

VI. Conclusion
Therefore, time-limited tolerances are
established for residues of
chlorantraniliprole, 3-bromo-N-[4chloro-2-methyl-6[(methylamino)carbonyl]phenyl]-1-(3chloro-2-pyridinyl)-1H-pyrazole-5carboxamide), in or on corn, sweet,
kernel plus cob with husks removed at
0.01 ppm; corn, sweet, forage at 6.0
ppm; corn, sweet, stover at 6.0 ppm;
corn, sweet, cannery waste at 6.0 ppm;
and milk at 0.03 ppm. These tolerances
expire and are revoked on December 31,
2011.

VII. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under sections 408(e) and 408(l)(6) 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 final rule has been
exempted from review under Executive
Order 12866, this final rule is not
subject to Executive Order 13211,
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 in accordance with
sections 408(e) and 408(l)(6) of FFDCA,
such as the tolerances in this final rule,
do not require the issuance of a
proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
Federalism (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled Consultation and Coordination
with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (Public Law 104–4).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act of 1995
(NTTAA), Public Law 104–113, section
12(d) (15 U.S.C. 272 note).
VIII. 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. Background and Statutory Findings
EPA, on its own initiative, in accordance with sections 408(e) and
408(l)(6) of FFDCA, 21 U.S.C. 346a(e) and 346a(1)(6), is establishing
time-limited tolerances for residues of the insecticide
chlorantraniliprole, 3-bromo-N-[4-chloro-2-methyl-6-
[(methylamino)carbonyl]phenyl]-1-(3-chloro-2-pyridinyl)-1H-pyrazole-5-
carboxamide), in or on corn, sweet, kernel plus cob with husks removed
at 0.01 parts per million (ppm); corn, sweet, forage at 6.0 ppm; corn,
sweet, stover at 6.0 ppm; corn, sweet, cannery waste at 6.0 ppm; and
milk at 0.03 ppm. These time-limited tolerances expire and are revoked
on December 31, 2011. EPA will publish a document in the Federal
Register to remove the revoked tolerances from the CFR.
Section 408(l)(6) of FFDCA requires EPA to establish a time-limited
tolerance or exemption from the requirement for a tolerance for
pesticide chemical residues in food that will result from the use of a
pesticide under an emergency exemption granted by EPA under section 18
of FIFRA. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
section 18 related time-limited tolerances to set binding precedents
for the application of section 408 of FFDCA and the new safety standard
to other tolerances and exemptions. Section 408(e) of FFDCA allows EPA
to establish a tolerance or an exemption from the requirement of a
tolerance on its own initiative, i.e., without having received any
petition from an outside party.
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. . .
.''
Section 18 of FIFRA authorizes EPA to exempt any Federal or State
agency from any provision of FIFRA, if EPA determines that ``emergency
conditions exist which require such exemption.'' EPA has established
regulations governing such emergency exemptions in 40 CFR part 166.
III. Emergency Exemption for Chlorantraniliprole on Sweet Corn and
FFDCA Tolerances
The states of Illinois and Minnesota requested the use of
chlorantraniliprole, formulated as the product Coragen (EPA Reg. No.
352-729), on sweet corn to control corn earworms. According to these
states, the available registered alternatives were not providing
adequate control of this pest and without the use of Coragen, growers
would suffer significant economic losses. After having reviewed the
submission, EPA determined that emergency conditions exist for these
States, and that the criteria for an emergency exemption are met. EPA
has authorized under FIFRA section 18 the use of chlorantraniliprole on
sweet corn for control of corn earworm in Illinois and Minnesota.
As part of its evaluation of the emergency exemption applications,
EPA assessed the potential risks presented by residues of
chlorantraniliprole in or on sweet corn and various associated sweet
corn-related commodities. In doing so, EPA considered the safety
standard in section 408(b)(2) of FFDCA, and EPA
[[Page 51729]]
decided that the necessary tolerances under section 408(l)(6) of FFDCA
would be consistent with the safety standard and with FIFRA section 18.
Consistent with the need to move quickly on the emergency exemption in
order to address an urgent non-routine situation and to ensure that the
resulting food is safe and lawful, EPA is issuing these tolerances
without notice and opportunity for public comment as provided in
section 408(l)(6) of FFDCA. Although these time-limited tolerances
expire and are revoked on December 31, 2011, under section 408(l)(5) of
FFDCA, residues of the pesticide not in excess of the amounts specified
in the tolerance remaining in or on these commodities after that date
will not be unlawful, provided the pesticide was applied in a manner
that was lawful under FIFRA, and the residues do not exceed a level
that was authorized by these time-limited tolerances at the time of
that application. EPA will take action to revoke these time-limited
tolerances earlier if any experience with, scientific data on, or other
relevant information on this pesticide indicate that the residues are
not safe.
Because these time-limited tolerances are being approved under
emergency conditions, EPA has not made any decisions about whether
chlorantraniliprole meets FIFRA's registration requirements for use on
sweet corn or whether permanent tolerances for this use would be
appropriate. Under these circumstances, EPA does not believe that these
time-limited tolerance decisions serve as a basis for registration of
chlorantraniliprole by a State for special local needs under FIFRA
section 24(c). Nor do these tolerances serve as the basis for persons
in any State other than Illinois and Minnesota to use this pesticide on
this crop under FIFRA section 18 absent the issuance of an emergency
exemption applicable within that State. For additional information
regarding the emergency exemption for chlorantraniliprole, contact the
Agency's Registration Division at the address provided under FOR
FURTHER INFORMATION CONTACT.
IV. 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 the factors specified in section 408(b)(2)(D) of
FFDCA, EPA has reviewed the available scientific data and other
relevant information in support of this action. EPA has sufficient data
to assess the hazards of and to make a determination on aggregate
exposure expected as a result of these emergency exemption requests and
the time-limited tolerances for residues of chlorantraniliprole on
corn, sweet, kernel plus cob with husks removed at 0.01 ppm; corn,
sweet, forage at 6.0 ppm; corn, sweet, stover at 6.0 ppm; corn, sweet,
cannery waste at 6.0 ppm; and milk at 0.03 ppm. EPA's assessment of
exposures and risks associated with establishing these time-limited
tolerances follows.
A. Toxicological Endpoints
For hazards that have a threshold below which there is no
appreciable risk, a toxicological point of departure (POD) is
identified as the basis for derivation of reference values for risk
assessment. The POD may be defined as the highest dose at which no
adverse effects are observed (the NOAEL) in the toxicology study
identified as appropriate for use in risk assessment. However, if a
NOAEL cannot be determined, the lowest dose at which adverse effects of
concern are identified (the LOAEL) or a Benchmark Dose (BMD) approach
is sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the POD to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
dietary risks by comparing aggregate food and water exposure to the
pesticide to the acute population adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The aPAD and cPAD are calculated by
dividing the POD by all applicable UFs. Aggregate short-, intermediate-
, and chronic-term risks are evaluated by comparing food, water, and
residential exposure to the POD to ensure that the margin of exposure
(MOE) called for by the product of all applicable UFs is not exceeded.
This latter value is referred to as the Level of Concern (LOC).
For non-threshold risks, the Agency assumes that any amount of
exposure will lead to some degree of risk. Thus, the Agency estimates
risk in terms of the probability of an occurrence of the adverse effect
greater than that expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/
pesticides/factsheets/riskassess.htm.

B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to chlorantraniliprole, EPA considered exposure under the
time-limited tolerance established by this action 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. No acute effects were identified in the dietary
toxicological studies for chlorantraniliprole; 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. EPA's chronic dietary exposure estimates for
chlorantriliprole are based on tolerance level residues, assuming 100%
crops associated with the existing uses and section 18 requests are
treated, and included the highest modeled estimated drinking water
concentration relevant to the scenario.
iii. Cancer. Chlorantraniliprole is classified as ``Not likely to
be Carcinogenic to Humans,'' and therefore a cancer exposure assessment
is unnecessary.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue and/or PCT
[[Page 51730]]
information in the dietary assessment for chlorantraniliprole.
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 chlorantraniliprole in drinking water. These simulation
models take into account data on the physical, chemical, and fate/
transport characteristics of chlorantraniliprole. 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 Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS) and Screening Concentration in Ground Water (SCI-
GROW) models, the estimated drinking water concentrations (EDWCs) of
chlorantraniliprole for chronic exposures for non-cancer assessments
are estimated to be 3.65 parts per billion (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. For chronic dietary risk
assessment, the water concentration of value 3.65 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).
Chlorantraniliprole is currently registered for the following uses
that could result in residential exposures: Turfgrass and ornamental
plants. EPA assessed residential exposure using the following
assumptions: Inhalation exposure is not expected due to low vapor
pressure; dermal postapplication exposure is possible for adults and
children for short- and intermediate-term durations, and exposure from
incidental oral ingestion is possible for children.
However, due to the lack of toxicity via the dermal route, as well
as the lack of toxicity over the acute, short- and intermediate- term
via the oral route, no risk is expected from these exposures.
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 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 substances found to have a common mechanism on EPA's website at
https://www.epa.gov/pesticides/cumulative.
C. 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 FQPA safety
factor (SF). In applying this provision, EPA either retains the default
value of 10X, or uses a different additional SF when reliable data
available to EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. Chlorantraniliprole did not
result in developmental toxicity in either rats or rabbits or in
reproductive effects in the multi-generation reproduction study. There
was no indication of increased offspring susceptibility in these
studies.
3. Conclusion. EPA has determined that reliable data show that 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 chlorantraniliprole is complete.
ii. There is no indication that chlorantraniliprole 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 chlorantraniliprole 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 chlorantraniliprole in drinking water. EPA used
similarly conservative assumptions to assess postapplication exposure
of children as well as incidental oral exposure of toddlers. These
assessments will not underestimate the exposure and risks posed by
chlorantraniliprole.
D. Aggregate Risks and Determination of Safety
EPA determines whether acute and chronic pesticide exposures are
safe by comparing aggregate exposure estimates to the aPAD and cPAD.
The aPAD and cPAD represent the highest safe exposures, taking into
account all appropriate SFs. EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs. For linear cancer risks, EPA
calculates the probability of additional cancer cases given the
estimated aggregate exposure. Short-, intermediate-, and chronic-term
risks are evaluated by comparing the estimated aggregate food, water,
and residential exposure to the POD to ensure that the MOE called for
by the product of all applicable UFs is not exceeded.
1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute dietary consumption of food and
drinking water. No adverse effect resulting from a single-oral exposure
was identified, therefore, chlorantraniliprole 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
chlorantraniliprole from food and water will utilize 1% of the cPAD for
(children 1-2 years old) the population group receiving the greatest
exposure.
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).
Although short-term residential exposure could occur with the use
of chlorantraniliprole, no toxicological effects resulting from short-
term dosing were observed. Therefore, the aggregate
[[Page 51731]]
short-term risk is the sum of the risk from 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 non-dietary, non-occupational
exposure plus chronic exposure to food and water (considered to be a
background exposure level).
Although intermediate-term residential exposure could result from
the use of chlorantraniliprole, no toxicological effects resulting from
intermediate-term dosing were observed. Therefore, the aggregate
intermediate-term risk is the sum of the risk from food and water and
will not be greater than the chronic aggregate risk.
5. Aggregate cancer risk for U.S. population. Chlorantraniliprole
is classified as ``Not likely to be Carcinogenic to Humans'' and is
therefore not expect to pose a cancer risk.
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 chlorantraniliprole residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology (LC/MS/MS) is available to enforce
the tolerance expression. The method may be requested from: Chief,
Analytical Chemistry Branch, Environmental Science Center, 701 Mapes
Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail
address: residuemethods@epa.gov.
B. International Residue Limits
There are no CODEX residue limits for residues of
chlorantraniliprole on sweet corn commodities or in milk.
VI. Conclusion
Therefore, time-limited tolerances are established for residues of
chlorantraniliprole, 3-bromo-N-[4-chloro-2-methyl-6-
[(methylamino)carbonyl]phenyl]-1-(3-chloro-2-pyridinyl)-1H-pyrazole-5-
carboxamide), in or on corn, sweet, kernel plus cob with husks removed
at 0.01 ppm; corn, sweet, forage at 6.0 ppm; corn, sweet, stover at 6.0
ppm; corn, sweet, cannery waste at 6.0 ppm; and milk at 0.03 ppm. These
tolerances expire and are revoked on December 31, 2011.
VII. Statutory and Executive Order Reviews
This final rule establishes tolerances under sections 408(e) and
408(l)(6) 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 final
rule has been exempted from review under Executive Order 12866, this
final rule is not subject to Executive Order 13211, 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 in accordance
with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VIII. 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).
