Federal Register / Vol. 83, No. 18 / Friday, January 26, 2018 / Rules and Regulations
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 chlorfenapyr in or
on tea, dried.
C. Revisions to Petitioned-for Tolerances
EPA is establishing a tolerance for
‘‘tea, dried’’, as opposed to ‘‘tea’’ as
requested by the petitioner, for
consistency with the Agency’s food and
feed commodity vocabulary. In
addition, EPA is amending the
introductory text of paragraph (a)(1) to
be consistent with the Agency’s policy
for drafting the tolerance expression.
These revisions reflect the language in
FFDCA section 408(a)(3), which
includes metabolites and degradates of
a pesticide chemical under the same
tolerance unless otherwise excluded, as
well as providing greater clarity for
measuring residues to determine
compliance. These revisions do not
substantively change the existing
tolerances in paragraph (a)(3).

V. Conclusion
Therefore, a tolerance is established
without U.S. registrations for residues of
chlorfenapyr, 4-bromo-2-(4-chloro
phenyl)-1-(ethoxymethyl)-5-(trifluro
methyl)-1H-pyrrole-3-carbonitrile, in or
on tea, dried at 70 parts per million.
VI. Statutory and Executive Order
Reviews
This action establishes a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001); Executive
Order 13045, entitled ‘‘Protection of
VerDate Sep<11>2014
17:29 Jan 25, 2018
Jkt 244001
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997); or Executive Order
13771, entitled ‘‘Reducing Regulations
and Controlling Regulatory Costs’’ (82
FR 9339, February 3, 2017). This action
does not contain any information
collections subject to OMB approval
under the Paperwork Reduction Act
(PRA) (44 U.S.C. 3501 et seq.), nor does
it require any special considerations
under Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the tolerance in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply
to this action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
VII. Congressional Review Act
Pursuant to the Congressional Review
Act (5 U.S.C. 801 et seq.), EPA will
submit a report containing this rule and
other required information to the U.S.

II. Background and Statutory Findings
EPA, on its own initiative, in
accordance with FFDCA sections 408(e)
and 408(l)(6) of, 21 U.S.C. 346a(e) and
346a(1)(6), is establishing time-limited
tolerances for residues of insecticide
flonicamid, N-(cyanomethyl)-4(trifluoromethyl)-3pyridinecarboxamide) and its
metabolites, TFNA (4trifluoromethylnicotinic acid), TFNAAM (4-trifluoromethylnicotinamide),
and TFNG (N-(4trifluoromethylnicotinoyl)glycine),
calculated as the stoichiometric
equivalent of flonicamid, in or on
prickly pear, fruit at 1.5 parts per
million (ppm) and prickly pear, pads at
1.5 ppm. These time-limited tolerances
expire on December 31, 2020.
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
Flonicamid on Prickly Pear, Fruit and
Prickly Pear, Pads and FFDCA
Tolerances
The California Department of
Pesticide Regulation (DPR) requested a
specific emergency exemption for the
use of flonicamid on prickly pear cactus
fruit (Opuntia spp.) and nopalitos (pads)
to control cochineal (Dactylopius
opuntiae) in Monterey County,
California. Cochineal insects are sapsucking, aggressive scale insects that are
considered to be a major pest for prickly
pear cactus. These insects damage the
cactus plant by inserting their mouth
parts into the cactus and feeding on the
plant’s sap. The feeding site of the
cactus begins to swell and discolor.
Eventually, the outer pads of the plant
will fall off and the entire cactus plant
dies. Cochineal colonies were first
observed in the Salinas Valley cactus
plantations in 2003. Birds heavily feed
on cactus fruit, and while feeding on
cochineal infected plants, the birds can
pick up the nymphs on their feet and
aid in spreading of the population. In
2013 and 2015 reduced amounts of
precipitation in Salinas, California
caused the cochineal population to
flourish and build to uncontrollable
levels. Even though 2016 and 2017
received normal levels of rain, cochineal
infestations have not been inhibited due
to the amount of cochineal present and
the ineffective control from registered
alternatives. As a result, growers are
experiencing significant damage to their
prickly pear cactus crops.
After having reviewed the
submission, EPA determined that an
emergency condition exists for this
State, 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 flonicamid on prickly pear,
fruit and prickly pear, pads for control
of cochineal in California.
VerDate Sep<11>2014
17:29 Jan 25, 2018
Jkt 244001
As part of its evaluation of the
emergency exemption application, EPA
assessed the potential risks presented by
residues of flonicamid in or on prickly
pear, fruit and prickly pear, pads. In
doing so, EPA considered the safety
standard in FFDCA section 408(b)(2),
and EPA decided that the necessary
tolerances 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
these tolerances without notice and
opportunity for public comment as
provided in FFDCA section 408(l)(6).
Although these time-limited tolerances
expire on December 31, 2020, under
FFDCA section 408(l)(5), residues of the
pesticide not in excess of the amounts
specified in the tolerance remaining in
or on prickly pear, fruit and prickly
pear, pads 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 flonicamid
meets FIFRA’s registration requirements
for use on prickly pear, fruit and prickly
pear, pads or whether permanent
tolerances for this use would be
appropriate. Under these circumstances,
EPA does not believe that this timelimited tolerance decision serves as a
basis for registration of flonicamid 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
California to use this pesticide on the
applicable crops under FIFRA section
18, absent the issuance of an emergency
exemption applicable within that State.

emergency exemption for flonicamid,

Division at the address provided under
FOR FURTHER INFORMATION CONTACT.
IV. Aggregate Risk Assessment and
Determination of Safety
Consistent with the factors specified
in FFDCA section 408(b)(2)(D), EPA has
reviewed the available scientific data
and other relevant information in
PO 00000
Frm 00050
Fmt 4700
Sfmt 4700
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 this emergency exemption request
and the time-limited tolerances for
residues of flonicamid on prickly pear,
fruit at 1.5 ppm and prickly pear, pads
at 1.5 ppm. EPA’s assessment of
exposures and risks associated with
establishing time-limited tolerances
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 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/pesticide-science-andassessing-pesticide-risks.
A summary of the toxicological
endpoints for flonicamid used for
human risk assessment is discussed in
Unit III.B. of the final rule published in
the Federal Register of November 14,
2012 (77 FR 67771) (FRL–9368–7).
B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to flonicamid, EPA considered
exposure expected under the timelimited tolerances established by this
action as well as all existing flonicamid
tolerances in 40 CFR 180.613. EPA
assessed dietary exposures from
flonicamid in food as follows:
i. Acute exposure. No acute effects
were observed at doses well above those
E:\FR\FM\26JAR1.SGM
26JAR1
daltland on DSKBBV9HB2PROD with RULES
Federal Register / Vol. 83, No. 18 / Friday, January 26, 2018 / Rules and Regulations
likely to be encountered; therefore, an
endpoint was not selected, and 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 NHANES/WWEIA
Survey. For the proposed section 18 use
of flonicamid on prickly pear, fruit and
pads, a dietary exposure assessment was
not performed because there was no
consumption reported for either
commodity in NHANES/WWEIA. Due
to the limited production and
availability of prickly pear commodities,
any increase in flonicamid dietary
exposure from consumption of prickly
pear commodities is expected to be
insignificant compared to the
flonicamid exposures pursuant to
existing tolerances for flonicamid on
various fruits and vegetables (40 CFR
180.613) which are produced in
significantly greater quantities that
prickly pear. These existing flonicamid
tolerances are based on conservative
(protective) exposure assumptions
including use of tolerance level residues
for all crops and 100% of the crops were
treated. Therefore, any additional
chronic risks from exposures of residues
of flonicamid on prickly pear would
likely be accounted for through the
conservative assumptions underlying
the existing tolerances.
iii. Cancer. As discussed in Unit III.B.
of the final rule published in the
Federal Register of November 14, 2012
(77 FR 67771), EPA has concluded that
a nonlinear RfD approach is appropriate
for assessing cancer risk to flonicamid.
For the same reasons discussed in Unit
IV.B.ii., regarding chronic exposure,
EPA believes that any additional cancer
risks from exposures of residues of
flonicamid on prickly pear would likely
be accounted for through the
conservative assumptions underlying
the existing tolerances.
iv. Anticipated residue and percent
crop treated (PCT) information. EPA did
not use anticipated residue and/or PCT
information in the dietary assessment
for flonicamid. Tolerance level residues
and 100% CT were assumed for all food
commodities included in the exposure
assessment.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for flonicamid in drinking water. These
simulation models take into account
data on the physical, chemical, and fate/
transport characteristics of flonicamid.
Further information regarding EPA
drinking water models used in pesticide
exposure assessment can be found at
VerDate Sep<11>2014
17:29 Jan 25, 2018
Jkt 244001
https://www.epa.gov/pesticide-scienceand-assessing-pesticide-risks/aboutwater-exposure-models-used-pesticide.
Based on the Pesticide Root Zone
Model Ground Water (PRZM GW), the
estimated drinking water concentrations
(EDWCs) of flonicamid for chronic
exposures for non-cancer assessments
are estimated to be 0.94 parts per billion
(ppb) for surface water and 9.92 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 value of 9.92 ppb
was used as the flonicamid contribution
from 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).
Flonicamid is not registered for any
specific use patterns that would result
in residential exposure. Further
information regarding EPA standard
assumptions and generic inputs for
residential exposures may be found at:
https://www.epa.gov/pesticide-scienceand-assessing-pesticide-risks/standardoperating-procedures-residentialpesticide.
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 flonicamid to
share a common mechanism of toxicity
with any other substances, and
flonicamid does not appear to produce
a toxic metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that flonicamid 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 website at https://
www.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides.
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
PO 00000
Frm 00051
Fmt 4700
Sfmt 4700
3613
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.
The prenatal and postnatal toxicity
database for flonicamid includes
prenatal developmental toxicity studies
in rats and rabbits and, a multigeneration reproduction toxicity study
in rats. There is no evidence that
flonicamid results in increased
susceptibility (qualitative or
quantitative) in utero in rats or rabbits
in the prenatal developmental studies or
in young rats in the multi-generation
reproduction study. No developmental
effects were seen in rabbits. In the
multi-generation reproduction study,
developmental delays in the offspring
(decreased body weights, delayed sexual
maturation) were seen only in the
presence of prenatal toxicity (kidney
and blood effects). Also, there are clear
NOAELs and LOAELs for all effects. The
degree of concern for prenatal and/or
postnatal susceptibility is, therefore low
due to the lack of evidence of qualitative
and quantitative susceptibility.
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, except where
assessing risk from inhalation exposure
as discussed below. Those decisions are
based on the following findings:
i. The toxicity database for flonicamid
is essentially complete, except for an
outstanding subchronic 28-day
inhalation study. In the absence of a
subchronic inhalation study, EPA has
retained a 10X FQPA SF to assess risk
from inhalation exposure, although at
present, residential inhalation exposure
is not expected from existing or pending
uses of flonicamid.
ii. There is no indication that
flonicamid 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
flonicamid 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 chronic dietary food exposure
assessment was based on 100 PCT,
tolerance-level residues and where
applicable, default processing factors.
EPA made conservative (protective)
assumptions in the ground and surface
water modeling used to assess exposure
to flonicamid in drinking water. These
assessments will not underestimate the
exposure and risks posed by flonicamid.
concluded that the cPAD is protective of
possible cancer effects from flonicamid
because, as noted in Unit IV.D.2,
aggregate chronic exposure to
flonicamid is below the cPAD.
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 flonicamid
residues.
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. An acute aggregate risk
assessment takes into account acute
exposure estimates from dietary
consumption of food and drinking
water. No adverse effects were observed
to result from single oral exposures at
doses well above those likely to be
encountered, and therefore, flonicamid
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 flonicamid
from food and water will utilize 59% of
the cPAD for (children 1–2 years old),
the population group receiving the
greatest exposure. There are no
residential uses for flonicamid.
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). Flonicamid is not
registered for any use patterns that
would result in short term residential
exposures.
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). Flonicamid is not
registered for any use patterns that
would result in intermediate-term
residential exposures.
5. Aggregate cancer risk for U.S.

referenced in Unit IV.A, EPA has

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 flonicamid.
VI. Conclusion
Therefore, time-limited tolerances are
established for residues of flonicamid,
N-(cyanomethyl)-4-(trifluoromethyl)-3pyridinecarboxamide) and its
metabolites, TFNA (4trifluoromethylnicotinic acid), TFNA–
AM (4-trifluoromethylnicotinamide),
and TFNG (N-(4trifluoromethylnicotinoyl)glycine),

equivalent of flonicamid, in or on
prickly pear, fruit at 1.5 ppm and
prickly pear, pads at 1.5 ppm. These
tolerances expire on December 31, 2020.
VII. Statutory and Executive Order
Reviews
This action 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,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001) or Executive
Order 13045, entitled ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997). This action does not
contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established 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 action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999) and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000) do not apply

does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section
12(d) of the National Technology
Transfer and Advancement Act
(NTTAA) (15 U.S.C. 272 note).
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

II. Background and Statutory Findings
EPA, on its own initiative, in accordance with FFDCA sections
408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(1)(6), is
establishing time-limited tolerances for residues of insecticide
flonicamid, N-(cyanomethyl)-4-(trifluoromethyl)-3-pyridinecarboxamide)
and its metabolites, TFNA (4-trifluoromethylnicotinic acid), TFNA-AM
(4-trifluoromethylnicotinamide), and TFNG (N-(4-
trifluoromethylnicotinoyl)glycine), calculated as the stoichiometric
equivalent of flonicamid, in or on prickly pear, fruit at 1.5 parts per
million (ppm) and prickly pear, pads at 1.5 ppm. These time-limited
tolerances expire on December 31, 2020.
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
[[Page 3612]]
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 Flonicamid on Prickly Pear, Fruit and
Prickly Pear, Pads and FFDCA Tolerances
The California Department of Pesticide Regulation (DPR) requested a
specific emergency exemption for the use of flonicamid on prickly pear
cactus fruit (Opuntia spp.) and nopalitos (pads) to control cochineal
(Dactylopius opuntiae) in Monterey County, California. Cochineal
insects are sap-sucking, aggressive scale insects that are considered
to be a major pest for prickly pear cactus. These insects damage the
cactus plant by inserting their mouth parts into the cactus and feeding
on the plant's sap. The feeding site of the cactus begins to swell and
discolor. Eventually, the outer pads of the plant will fall off and the
entire cactus plant dies. Cochineal colonies were first observed in the
Salinas Valley cactus plantations in 2003. Birds heavily feed on cactus
fruit, and while feeding on cochineal infected plants, the birds can
pick up the nymphs on their feet and aid in spreading of the
population. In 2013 and 2015 reduced amounts of precipitation in
Salinas, California caused the cochineal population to flourish and
build to uncontrollable levels. Even though 2016 and 2017 received
normal levels of rain, cochineal infestations have not been inhibited
due to the amount of cochineal present and the ineffective control from
registered alternatives. As a result, growers are experiencing
significant damage to their prickly pear cactus crops.
After having reviewed the submission, EPA determined that an
emergency condition exists for this State, 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 flonicamid on
prickly pear, fruit and prickly pear, pads for control of cochineal in
California.
As part of its evaluation of the emergency exemption application,
EPA assessed the potential risks presented by residues of flonicamid in
or on prickly pear, fruit and prickly pear, pads. In doing so, EPA
considered the safety standard in FFDCA section 408(b)(2), and EPA
decided that the necessary tolerances 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 these tolerances
without notice and opportunity for public comment as provided in FFDCA
section 408(l)(6). Although these time-limited tolerances expire on
December 31, 2020, under FFDCA section 408(l)(5), residues of the
pesticide not in excess of the amounts specified in the tolerance
remaining in or on prickly pear, fruit and prickly pear, pads 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
flonicamid meets FIFRA's registration requirements for use on prickly
pear, fruit and prickly pear, pads 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 flonicamid 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 California 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
flonicamid, contact the Agency's Registration Division at the address
provided under FOR FURTHER INFORMATION CONTACT.
IV. Aggregate Risk Assessment and Determination of Safety
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 this emergency exemption request and
the time-limited tolerances for residues of flonicamid on prickly pear,
fruit at 1.5 ppm and prickly pear, pads at 1.5 ppm. EPA's assessment of
exposures and risks associated with establishing time-limited
tolerances 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 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/pesticide-science-and-assessing-pesticide-risks.
A summary of the toxicological endpoints for flonicamid used for
human risk assessment is discussed in Unit III.B. of the final rule
published in the Federal Register of November 14, 2012 (77 FR 67771)
(FRL-9368-7).
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to flonicamid, EPA considered exposure expected under the
time-limited tolerances established by this action as well as all
existing flonicamid tolerances in 40 CFR 180.613. EPA assessed dietary
exposures from flonicamid in food as follows:
i. Acute exposure. No acute effects were observed at doses well
above those
[[Page 3613]]
likely to be encountered; therefore, an endpoint was not selected, and
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 NHANES/
WWEIA Survey. For the proposed section 18 use of flonicamid on prickly
pear, fruit and pads, a dietary exposure assessment was not performed
because there was no consumption reported for either commodity in
NHANES/WWEIA. Due to the limited production and availability of prickly
pear commodities, any increase in flonicamid dietary exposure from
consumption of prickly pear commodities is expected to be insignificant
compared to the flonicamid exposures pursuant to existing tolerances
for flonicamid on various fruits and vegetables (40 CFR 180.613) which
are produced in significantly greater quantities that prickly pear.
These existing flonicamid tolerances are based on conservative
(protective) exposure assumptions including use of tolerance level
residues for all crops and 100% of the crops were treated. Therefore,
any additional chronic risks from exposures of residues of flonicamid
on prickly pear would likely be accounted for through the conservative
assumptions underlying the existing tolerances.
iii. Cancer. As discussed in Unit III.B. of the final rule
published in the Federal Register of November 14, 2012 (77 FR 67771),
EPA has concluded that a nonlinear RfD approach is appropriate for
assessing cancer risk to flonicamid. For the same reasons discussed in
Unit IV.B.ii., regarding chronic exposure, EPA believes that any
additional cancer risks from exposures of residues of flonicamid on
prickly pear would likely be accounted for through the conservative
assumptions underlying the existing tolerances.
iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue and/or PCT information in the
dietary assessment for flonicamid. Tolerance level residues and 100% CT
were assumed for all food commodities included in the exposure
assessment.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for flonicamid in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of flonicamid. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
Based on the Pesticide Root Zone Model Ground Water (PRZM GW), the
estimated drinking water concentrations (EDWCs) of flonicamid for
chronic exposures for non-cancer assessments are estimated to be 0.94
parts per billion (ppb) for surface water and 9.92 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 value of 9.92 ppb was used as the
flonicamid contribution from 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).
Flonicamid is not registered for any specific use patterns that would
result in residential exposure. Further information regarding EPA
standard assumptions and generic inputs for residential exposures may
be found at: https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
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 flonicamid to share a common mechanism of
toxicity with any other substances, and flonicamid does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
flonicamid 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 website at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
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. The prenatal and postnatal
toxicity database for flonicamid includes prenatal developmental
toxicity studies in rats and rabbits and, a multi-generation
reproduction toxicity study in rats. There is no evidence that
flonicamid results in increased susceptibility (qualitative or
quantitative) in utero in rats or rabbits in the prenatal developmental
studies or in young rats in the multi-generation reproduction study. No
developmental effects were seen in rabbits. In the multi-generation
reproduction study, developmental delays in the offspring (decreased
body weights, delayed sexual maturation) were seen only in the presence
of prenatal toxicity (kidney and blood effects). Also, there are clear
NOAELs and LOAELs for all effects. The degree of concern for prenatal
and/or postnatal susceptibility is, therefore low due to the lack of
evidence of qualitative and quantitative susceptibility.
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, except where assessing risk from inhalation
exposure as discussed below. Those decisions are based on the following
findings:
i. The toxicity database for flonicamid is essentially complete,
except for an outstanding subchronic 28-day inhalation study. In the
absence of a subchronic inhalation study, EPA has retained a 10X FQPA
SF to assess risk from inhalation exposure, although at present,
residential inhalation exposure is not expected from existing or
pending uses of flonicamid.
ii. There is no indication that flonicamid 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 flonicamid 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.
[[Page 3614]]
iv. There are no residual uncertainties identified in the exposure
databases. The chronic dietary food exposure assessment was based on
100 PCT, tolerance-level residues and where applicable, default
processing factors. EPA made conservative (protective) assumptions in
the ground and surface water modeling used to assess exposure to
flonicamid in drinking water. These assessments will not underestimate
the exposure and risks posed by flonicamid.
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. An acute aggregate risk assessment takes into
account acute exposure estimates from dietary consumption of food and
drinking water. No adverse effects were observed to result from single
oral exposures at doses well above those likely to be encountered, and
therefore, flonicamid 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
flonicamid from food and water will utilize 59% of the cPAD for
(children 1-2 years old), the population group receiving the greatest
exposure. There are no residential uses for flonicamid.
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). Flonicamid is
not registered for any use patterns that would result in short term
residential exposures.
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). Flonicamid is not registered for any use
patterns that would result in intermediate-term residential exposures.
5. Aggregate cancer risk for U.S. population. Based on the
information referenced in Unit IV.A, EPA has concluded that the cPAD is
protective of possible cancer effects from flonicamid because, as noted
in Unit IV.D.2, aggregate chronic exposure to flonicamid is below the
cPAD.
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 flonicamid residues.
V. Other Considerations
A. Analytical Enforcement Methodology
An adequate enforcement methodology (FMC Method No. P-3561M, a
liquid chromatography with tandem mass spectrometry (LC/MS/MS) method
is available to enforce the tolerance expression for flonicamid and its
metabolites in or on plant commodities. 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: [email protected].
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 flonicamid.
VI. Conclusion
Therefore, time-limited tolerances are established for residues of
flonicamid, N-(cyanomethyl)-4-(trifluoromethyl)-3-pyridinecarboxamide)
and its metabolites, TFNA (4-trifluoromethylnicotinic acid), TFNA-AM
(4-trifluoromethylnicotinamide), and TFNG (N-(4-
trifluoromethylnicotinoyl)glycine), calculated as the stoichiometric
equivalent of flonicamid, in or on prickly pear, fruit at 1.5 ppm and
prickly pear, pads at 1.5 ppm. These tolerances expire on December 31,
2020.
VII. Statutory and Executive Order Reviews
This action 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, October 4, 1993).
Because this action has been exempted from review under Executive Order
12866, this action is not subject to Executive Order 13211, entitled
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) or Executive
Order 13045, entitled ``Protection of Children from Environmental
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997). This
action does not contain any information collections subject to OMB
approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et
seq., nor does it require any special considerations under Executive
Order 12898, entitled ``Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations'' (59 FR
7629, February 16, 1994).
Since tolerances and exemptions that are established 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 action directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of FFDCA section 408(n)(4). As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled ``Federalism'' (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
``Consultation and Coordination with Indian Tribal Governments'' (65 FR
67249, November 9, 2000) do not apply
[[Page 3615]]
to this action. In addition, this action does not impose any
enforceable duty or contain any unfunded mandate as described under
Title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et
seq.).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act (NTTAA) (15 U.S.C. 272 note).
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).
