II. Background and Statutory Findings
EPA, on its own initiative, in
accordance with FFDCA sections 408(e)
and 408(l)(6), 21 U.S.C. 346a(e) and
346a(1)(6), is establishing a time-limited
tolerance for residues of spirotetramat,
including its metabolites and
degradates, in or on watercress at 1.5
parts per million (ppm). This timelimited tolerance expires on December
31, 2015.
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 FIFRA section 18. Such
tolerances can be established without
providing notice or period for public
comment. EPA does not intend for its
actions on FIFRA section 18 related
VerDate Mar<15>2010
04:58 Dec 22, 2012
Jkt 229001
time-limited tolerances to set binding
precedents for the application of FFDCA
section 408 and the 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
Spirotetramat on Watercress and
FFDCA Tolerances
This is the first Section 18 request
received for the use of spirotetramat on
watercress. Florida and Tennessee are
experiencing high pest pressure from
melon/cotton aphids in the watercress
industry. Aphids infest watercress fields
from surrounding areas, and attack the
apical stem tips of plants. Watercress
plants respond with reduced vigor
(growth rate) and yields per acre (bunch
number) are subsequently reduced. Due
to lack of effective alternative
insecticides, increasing resistance to the
historically effective insecticide
imidacloprid, and marketable yield
losses, the Agency has determined the
situation is non-routine and urgent and
likely to result in significant economic
losses. After having reviewed the
submission, EPA determined that an
emergency condition exists for these
States, and that the criteria for approval
PO 00000
Frm 00034
Fmt 4700
Sfmt 4700
of an emergency exemption are met.
EPA has authorized a specific
exemption under FIFRA section 18 for
the use of spirotetramat on watercress
for control of melon/cotton aphids in
Florida and Tennessee.
As part of its evaluation of the
emergency exemption application, EPA
assessed the potential risks presented by
residues of spirotetramat in or on
watercress. In doing so, EPA considered
the safety standard in FFDCA section
408(b)(2), and EPA decided that the
necessary tolerance under FFDCA
section 408(l)(6) 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 this tolerance without
notice and opportunity for public
comment as provided in FFDCA section
408(l)(6). Although these time-limited
tolerances expire on December 31, 2015,
under FFDCA section 408(l)(5), residues
of the pesticide not in excess of the
amounts specified in the tolerance
remaining in or on watercress 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 spirotetramat
meets FIFRA’s registration requirements
for use on watercress or whether
permanent tolerances for this use would
be appropriate. Under these
circumstances, EPA does not believe
that this time-limited tolerance decision
serves as a basis for registration of
spirotetramat by a State for special local
needs under FIFRA section 24(c). Nor
does this tolerance by itself serve as the
authority for persons in any State, other
than Florida and Tennessee, to use this
pesticide on the applicable crops under
FIFRA section 18 absent the issuance of
an emergency exemption applicable
within that State. For additional
information regarding the emergency
exemption for spirotetramat, 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 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 expected as a result
of the emergency exemption requests
and the time-limited tolerance for
residues of spirotetramat, including its
metabolites and degradates, in or on
watercress at 1.5 ppm. EPA’s assessment
of exposures and risks associated with
establishing a time-limited tolerance
follows.

A. 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 (LOC) 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
VerDate Mar<15>2010
04:58 Dec 22, 2012
Jkt 229001
of exposure (MOE). For non-threshold
risks, the Agency assumes that any
amount of exposure will lead to some
degree of risk. Thus, the Agency
estimates risk in terms of the probability
of an occurrence of the adverse effect
expected in a lifetime. For more
information on the general principles
EPA uses in risk characterization and a
complete description of the risk
assessment process, see https://
www.epa.gov/pesticides/factsheets/
riskassess.htm. A summary of the
toxicological endpoints for
spirotetramat used for human risk
assessment is discussed in Unit III.B. of
the final rule published in the Federal
Register of May 18, 2011 (76 FR 28675)
(FRL–8865–8).
B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to spirotetramat, EPA
considered exposure under the timelimited tolerance established by this
action as well as all existing
spirotetramat tolerances in § 180.641.
EPA assessed dietary exposures from
spirotetramat in food as follows:
i. Acute and chronic exposure. Such
effects were identified for spirotetramat.
In estimating acute and chronic dietary
exposure, EPA used food consumption
information from the U.S. Department of
Agriculture (USDA) 1994–1996 and
1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). As
to residue levels in food, EPA used
tolerance-level residues and 100 percent
crop treated (PCT) for all commodities.
Empirical processing factors were used
for apple, orange, grape and tomato
juice, applesauce, and dried apples, and
Dietary Exposure Evaluation Model
(DEEM (Ver. 7.81)) default processing
factors were used for the remaining
processed commodities (where
provided).
ii. Cancer. Based on the data
summarized in Unit IV.A., EPA has
concluded that spirotetramat does not
pose a cancer risk to humans. Therefore,
a dietary exposure assessment for the
purpose of assessing cancer risk is
unnecessary.
iii. Anticipated residue and PCT
information. EPA did not use
anticipated residue and/or PCT
information in the dietary assessment
for spirotetramat. 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 spirotetramat in drinking water.
These simulation models take into
PO 00000
Frm 00035
Fmt 4700
Sfmt 4700
75857
account data on the physical, chemical,
and fate/transport characteristics of
spirotetramat. 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 Tier 1 Rice Model and
Screening Concentration in Ground
Water (SCI–GROW) models, the
estimated drinking water concentrations
(EDWCs) of total toxic residues (TTR) of
spirotetramat, spirotetramat-enol, and
spirotetramat-ketohydroxy for acute and
chronic exposures are estimated to be
158 parts per billion (ppb) for surface
water and 3.96 × 10¥4 ppb for ground
water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
acute and chronic dietary risk
assessment, the water concentration
value of 158 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). There are
currently no registered or proposed
residential uses for spirotetramat;
therefore a residential exposure
assessment was not conducted.
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 spirotetramat to
share a common mechanism of toxicity
with any other substances, and
spirotetramat does not appear to
produce a toxic metabolite produced by
other substances. For the purposes of
this tolerance action, therefore, EPA has
assumed that spirotetramat does not
have a common mechanism of toxicity
with other substances. For information
regarding EPA’s efforts to determine
which chemicals have a common
mechanism of toxicity and to evaluate
the cumulative effects of such
chemicals, see EPA’s Web site at
https://www.epa.gov/pesticides/
cumulative.
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
E:\FR\FM\26DER1.SGM
26DER1
tkelley on DSK3SPTVN1PROD with
75858
Federal Register / Vol. 77, No. 247 / Wednesday, December 26, 2012 / Rules and Regulations
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 SF when reliable data
available to EPA support the choice of
a different factor.
2. Prenatal and postnatal sensitivity.
Based on the results of developmental
toxicity studies in rats and rabbits and
two reproduction studies in rats with
spirotetramat, there was no evidence of
increased susceptibility of offspring
following prenatal or postnatal
exposure.
3. Conclusion. EPA has determined
that reliable data show that the safety of
infants and children would be
adequately protected if the Food Quality
Protection Act (Pub. L. 104–170) Safety
Factor (FQPA SF) were reduced to 1X.
That decision is based on the following
findings:
i. The toxicity database for
spirotetramat is complete, except for a
subchronic neurotoxicity study which is
now required as part of the revisions to
40 CFR part 158. However, the existing
toxicological database indicates that
spirotetramat is not a neurotoxic
chemical in mammals. In addition,
acute, subchronic and developmental
neurotoxicity studies available for
structurally-related compounds
(spirodiclofen and spiromesifen) do not
show evidence of neurotoxicity in
adults or young.
ii. There is no indication that
spirotetramat 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
spirotetramat results in increased
susceptibility in in utero rats or rabbits
in the prenatal developmental studies or
in young rats, in both the 1- and 2generation reproduction studies.
iv. There are no residual uncertainties
identified in the exposure databases that
will result in underestimation of
exposure. 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 spirotetramat in drinking water.
These assessments will not
VerDate Mar<15>2010
04:58 Dec 22, 2012
Jkt 229001
underestimate the exposure and risks
posed by spirotetramat.
D. 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. Using the exposure
assumptions discussed in this unit for
acute exposure, the acute dietary
exposure from food and water to
spirotetramat will occupy 10% of the
aPAD for children ages 1–2 years old,
the population group receiving the
greatest exposure.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to spirotetramat
from food and water will utilize 83% of
the cPAD for children ages 1–2 years
old, the population group receiving the
greatest exposure. There are no
residential uses for spirotetramat.
3. Short-term and Intermediate-term
risk. Short- and intermediate-term
aggregate exposure takes into account
short-term and intermediate-term
residential exposure plus chronic
exposure to food and water (considered
to be a background exposure level). A
short-term and intermediate-term
adverse effect was identified; however,
spirotetramat is not registered for any
use patterns that would result in shortterm or intermediate-term residential
exposure. Short-term and intermediateterm risk is assessed based on shortterm or intermediate-term residential
exposure plus chronic dietary exposure.
Because there is no short-term 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-term risk), no further
assessment of short-term or
intermediate-term risk is necessary, and
EPA relies on the chronic dietary risk
assessment for evaluating short-term
and intermediate-term risk for
spirotetramat.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent carcinogenicity studies,
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
spirotetramat 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 spirotetramat
residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology,
high-performance liquid
chromatography with tandem
spectrometry (HPLC–MS/MS), is
available to enforce the tolerance
expression.
The method may be requested from:

B. International Residue Limits
In making its tolerance decisions, EPA
seeks to harmonize U.S. tolerances with
international standards whenever
possible, consistent with U.S. food
safety standards and agricultural
practices. EPA considers the
international maximum residue limits
(MRLs) established by the Codex
Alimentarius Commission (Codex), as
required by FFDCA section 408(b)(4).
The Codex Alimentarius is a joint
United Nations Food and Agriculture
Organization/World Health
Organization food standards program,
and it is recognized as an international
food safety standards-setting
organization in trade agreements to
which the United States is a party. EPA
may establish a tolerance that is
different from a Codex MRL; however,
FFDCA section 408(b)(4) requires that
EPA explain the reasons for departing
from the Codex level. The Codex has not
established a MRL for spirotetramat.
VI. Conclusion
Therefore, time-limited tolerances are
established for residues of spirotetramat,
including its metabolites and
degradates, in or on watercress at 1.5
ppm. This tolerance expires on
December 31, 2015.
VII. Statutory and Executive Order
Reviews
This final rule establishes tolerances
under FFDCA sections 408(e) and
408(l)(6). 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,
E:\FR\FM\26DER1.SGM
26DER1
tkelley on DSK3SPTVN1PROD with
Federal Register / Vol. 77, No. 247 / Wednesday, December 26, 2012 / Rules and Regulations
October 4, 1993). Because this final rule
has been exempted from review under
Executive Order 12866, this final rule is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This final rule does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established in accordance with
FFDCA sections 408(e) and 408(l)(6),
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 FFDCA section 408(n)(4). As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this final rule. In addition, this final
rule does not impose any enforceable
duty or contain any unfunded mandate
as described under Title II of the
Unfunded Mandates Reform Act of 1995
(UMRA) (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 of 1995
(NTTAA) (15 U.S.C. 272 note).

VIII. 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

II. Background and Statutory Findings
EPA, on its own initiative, in accordance with FFDCA sections
408(e) and 408(l)(6), 21 U.S.C. 346a(e) and 346a(1)(6), is establishing
a time-limited tolerance for residues of spirotetramat, including its
metabolites and degradates, in or on watercress at 1.5 parts per
million (ppm). This time-limited tolerance expires on December 31,
2015.
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 FIFRA
section 18. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
FIFRA section 18 related time-limited tolerances to set binding
precedents for the application of FFDCA section 408 and the 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 Spirotetramat on Watercress and FFDCA
Tolerances
This is the first Section 18 request received for the use of
spirotetramat on watercress. Florida and Tennessee are experiencing
high pest pressure from melon/cotton aphids in the watercress industry.
Aphids infest watercress fields from surrounding areas, and attack the
apical stem tips of plants. Watercress plants respond with reduced
vigor (growth rate) and yields per acre (bunch number) are subsequently
reduced. Due to lack of effective alternative insecticides, increasing
resistance to the historically effective insecticide imidacloprid, and
marketable yield losses, the Agency has determined the situation is
non-routine and urgent and likely to result in significant economic
losses. After having reviewed the submission, EPA determined that an
emergency condition exists for these States, and that the criteria for
approval of an emergency exemption are met. EPA has authorized a
specific exemption under FIFRA section 18 for the use of spirotetramat
on watercress for control of melon/cotton aphids in Florida and
Tennessee.
As part of its evaluation of the emergency exemption application,
EPA assessed the potential risks presented by residues of spirotetramat
in or on watercress. In doing so, EPA considered the safety standard in
FFDCA section 408(b)(2), and EPA decided that the necessary tolerance
under FFDCA section 408(l)(6) 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 this tolerance without notice and opportunity
for public comment as provided in FFDCA section 408(l)(6). Although
these time-limited tolerances expire on December 31, 2015, under FFDCA
section 408(l)(5), residues of the pesticide not in excess of the
amounts specified in the tolerance remaining in or on watercress 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
spirotetramat meets FIFRA's registration requirements for use on
watercress or whether permanent tolerances for this use would be
appropriate. Under these circumstances, EPA does not believe that this
time-limited tolerance decision serves as a basis for registration of
spirotetramat by a State for special local needs under FIFRA section
24(c). Nor does this tolerance by itself serve as the authority for
persons in any State, other than Florida and Tennessee, to use this
pesticide on the applicable crops under FIFRA section 18 absent the
issuance of an emergency exemption applicable within that State. For
additional information regarding the emergency exemption for
spirotetramat, contact the Agency's Registration Division at the
address provided under FOR FURTHER INFORMATION CONTACT.
[[Page 75857]]
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 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 expected as a result of the emergency exemption requests and
the time-limited tolerance for residues of spirotetramat, including its
metabolites and degradates, in or on watercress at 1.5 ppm. EPA's
assessment of exposures and risks associated with establishing a time-
limited tolerance follows.
A. 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 (LOC) to use in evaluating the risk posed by human exposure to
the pesticide. For hazards that have a threshold below which there is
no appreciable risk, the toxicological POD is used as the basis for
derivation of reference values for risk assessment. PODs are developed
based on a careful analysis of the doses in each toxicological study to
determine the dose at which no adverse effects are observed (the NOAEL)
and the lowest dose at which adverse effects of concern are identified
(the LOAEL). Uncertainty/safety factors are used in conjunction with
the POD to calculate a safe exposure level--generally referred to as a
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe
margin of exposure (MOE). For non-threshold risks, the Agency assumes
that any amount of exposure will lead to some degree of risk. Thus, the
Agency estimates risk in terms of the probability of an occurrence of
the adverse effect expected in a lifetime. For more information on the
general principles EPA uses in risk characterization and a complete
description of the risk assessment process, see https://www.epa.gov/pesticides/factsheets/riskassess.htm. A summary of the toxicological
endpoints for spirotetramat used for human risk assessment is discussed
in Unit III.B. of the final rule published in the Federal Register of
May 18, 2011 (76 FR 28675) (FRL-8865-8).
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to spirotetramat, EPA considered exposure under the time-
limited tolerance established by this action as well as all existing
spirotetramat tolerances in Sec. 180.641. EPA assessed dietary
exposures from spirotetramat in food as follows:
i. Acute and chronic exposure. Such effects were identified for
spirotetramat. In estimating acute and chronic dietary exposure, EPA
used food consumption information from the U.S. Department of
Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). As to residue levels in food, EPA
used tolerance-level residues and 100 percent crop treated (PCT) for
all commodities. Empirical processing factors were used for apple,
orange, grape and tomato juice, applesauce, and dried apples, and
Dietary Exposure Evaluation Model (DEEM (Ver. 7.81)) default processing
factors were used for the remaining processed commodities (where
provided).
ii. Cancer. Based on the data summarized in Unit IV.A., EPA has
concluded that spirotetramat does not pose a cancer risk to humans.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
iii. Anticipated residue and PCT information. EPA did not use
anticipated residue and/or PCT information in the dietary assessment
for spirotetramat. 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 spirotetramat in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of spirotetramat. 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 Tier 1 Rice Model and Screening Concentration in
Ground Water (SCI-GROW) models, the estimated drinking water
concentrations (EDWCs) of total toxic residues (TTR) of spirotetramat,
spirotetramat-enol, and spirotetramat-ketohydroxy for acute and chronic
exposures are estimated to be 158 parts per billion (ppb) for surface
water and 3.96 x 10-4 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute and chronic dietary
risk assessment, the water concentration value of 158 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). There are currently
no registered or proposed residential uses for spirotetramat; therefore
a residential exposure assessment was not conducted.
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 spirotetramat to share a common mechanism of
toxicity with any other substances, and spirotetramat does not appear
to produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
spirotetramat does not have a common mechanism of toxicity with other
substances. For information regarding EPA's efforts to determine which
chemicals have a common mechanism of toxicity and to evaluate the
cumulative effects of such chemicals, see EPA's Web site at https://www.epa.gov/pesticides/cumulative.
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
[[Page 75858]]
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 SF when reliable data available to
EPA support the choice of a different factor.
2. Prenatal and postnatal sensitivity. Based on the results of
developmental toxicity studies in rats and rabbits and two reproduction
studies in rats with spirotetramat, there was no evidence of increased
susceptibility of offspring following prenatal or postnatal exposure.
3. Conclusion. EPA has determined that reliable data show that the
safety of infants and children would be adequately protected if the
Food Quality Protection Act (Pub. L. 104-170) Safety Factor (FQPA SF)
were reduced to 1X. That decision is based on the following findings:
i. The toxicity database for spirotetramat is complete, except for
a subchronic neurotoxicity study which is now required as part of the
revisions to 40 CFR part 158. However, the existing toxicological
database indicates that spirotetramat is not a neurotoxic chemical in
mammals. In addition, acute, subchronic and developmental neurotoxicity
studies available for structurally-related compounds (spirodiclofen and
spiromesifen) do not show evidence of neurotoxicity in adults or young.
ii. There is no indication that spirotetramat 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 spirotetramat results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or in young rats, in both the 1- and 2-generation
reproduction studies.
iv. There are no residual uncertainties identified in the exposure
databases that will result in underestimation of exposure. 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 spirotetramat in drinking water. These assessments will not
underestimate the exposure and risks posed by spirotetramat.
D. 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. Using the exposure assumptions discussed in this
unit for acute exposure, the acute dietary exposure from food and water
to spirotetramat will occupy 10% of the aPAD for children ages 1-2
years old, the population group receiving the greatest exposure.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
spirotetramat from food and water will utilize 83% of the cPAD for
children ages 1-2 years old, the population group receiving the
greatest exposure. There are no residential uses for spirotetramat.
3. Short-term and Intermediate-term risk. Short- and intermediate-
term aggregate exposure takes into account short-term and intermediate-
term residential exposure plus chronic exposure to food and water
(considered to be a background exposure level). A short-term and
intermediate-term adverse effect was identified; however, spirotetramat
is not registered for any use patterns that would result in short-term
or intermediate-term residential exposure. Short-term and intermediate-
term risk is assessed based on short-term or intermediate-term
residential exposure plus chronic dietary exposure. Because there is no
short-term 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-term risk), no further assessment of short-term or
intermediate-term risk is necessary, and EPA relies on the chronic
dietary risk assessment for evaluating short-term and intermediate-term
risk for spirotetramat.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent carcinogenicity
studies, spirotetramat 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 spirotetramat residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodology, high-performance liquid
chromatography with tandem spectrometry (HPLC-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; email address:
residuemethods@epa.gov.
B. International Residue Limits
In making its tolerance decisions, EPA seeks to harmonize U.S.
tolerances with international standards whenever possible, consistent
with U.S. food safety standards and agricultural practices. EPA
considers the international maximum residue limits (MRLs) established
by the Codex Alimentarius Commission (Codex), as required by FFDCA
section 408(b)(4). The Codex Alimentarius is a joint United Nations
Food and Agriculture Organization/World Health Organization food
standards program, and it is recognized as an international food safety
standards-setting organization in trade agreements to which the United
States is a party. EPA may establish a tolerance that is different from
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain
the reasons for departing from the Codex level. The Codex has not
established a MRL for spirotetramat.
VI. Conclusion
Therefore, time-limited tolerances are established for residues of
spirotetramat, including its metabolites and degradates, in or on
watercress at 1.5 ppm. This tolerance expires on December 31, 2015.
VII. Statutory and Executive Order Reviews
This final rule establishes tolerances under FFDCA sections 408(e)
and 408(l)(6). 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,
[[Page 75859]]
October 4, 1993). Because this final rule has been exempted from review
under Executive Order 12866, this final rule is not subject to
Executive Order 13211, entitled ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR
28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of
Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled ``Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established in accordance
with FFDCA sections 408(e) and 408(l)(6), 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 FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (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 of 1995 (NTTAA) (15 U.S.C. 272 note).
VIII. 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).
