II. Background and Statutory Findings
EPA, on its own initiative, in
accordance with sections 408(e) and
408(l)(6) of the Federal Food, Drug, and
Cosmetic Act (FFDCA), 21 U.S.C.
346a(e) and 346a(1)(6), is establishing
time-limited tolerances for combined
residues of the fungicide cyazofamid, in
or on fresh basil at 12 parts per million
(ppm), and on dried basil at 144 ppm.
These time-limited tolerances expire on
December 31, 2014.

Federal Register / Vol. 77, No. 18 / Friday, January 27, 2012 / Rules and Regulations
pmangrum on DSK3VPTVN1PROD with RULES
Section 408(l)(6) of FFDCA requires
EPA to establish a time-limited
tolerance or exemption from the
requirement for a tolerance for pesticide
chemical residues in food that will
result from the use of a pesticide under
an emergency exemption granted by
EPA under section 18 of FIFRA. Such
tolerances can be established without
providing notice or period for public
comment. EPA does not intend for its
actions on FIFRA section 18 related
time-limited tolerances to set binding
precedents for the application of section
408 of FFDCA 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
Cyazofamid on Basil and FFDCA
Tolerances
The Illinois Department of
Agriculture (IDA) submitted a Section
18 Specific Exemption request (10IL02).
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 were met. EPA has
authorized a specific exemption under
FIFRA section 18 for the use of
VerDate Mar<15>2010
15:16 Jan 26, 2012
Jkt 226001
cyazofamid on basil for control of
downy mildew (Peronospora balbahrii)
in Illinois. This new food use for
cyazofamid triggered the requirement
for the establishment of tolerances
under FFDCA.
As part of its evaluation of the
emergency exemption application, EPA
assessed the potential risks presented by
residues of cyazofamid in or on basil. In
doing so, EPA considered the safety
standard in section 408(b)(2) of FFDCA,
and EPA decided that the necessary
tolerance under section 408(l)(6) of
FFDCA would be consistent with the
safety standard and with FIFRA section
18. Consistent with the need to move
quickly on the emergency exemption in
order to address an urgent non-routine
situation and to ensure that the resulting
food is safe and lawful, EPA is issuing
this tolerance without notice and
opportunity for public comment as
provided in section 408(l)(6) of FFDCA.
Although these time-limited tolerances
expire on December 31, 2014, under
section 408(l)(5) of FFDCA, residues of
the pesticide not in excess of the
amounts specified in the tolerance
remaining in or on basil 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 cyazofamid
meets FIFRA’s registration requirements
for use on basil 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 cyazofamid 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
Illinois 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 cyazofamid,

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
combined residues of cyazofamid on
fresh basil at 12 ppm, and on dried basil
at 144 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/pesticides/factsheets/
riskassess.htm.
A summary of the toxicological
endpoints for cyazofamid used for
human risk assessment is discussed in
Unit III. B. of the final rule published in
the Federal Register of July 14, 2010 (75
FR 40745) (FRL–8833–1).
B. Exposure Assessment
1. Dietary exposure from food and
feed uses. In evaluating dietary
exposure to cyazofamid, EPA
considered exposure under the time-
E:\FR\FM\27JAR1.SGM
27JAR1
pmangrum on DSK3VPTVN1PROD with RULES
4250
Federal Register / Vol. 77, No. 18 / Friday, January 27, 2012 / Rules and Regulations
limited tolerances established by this
action as well as all existing cyazofamid
tolerances in 40 CFR 180.601. EPA
assessed dietary exposures from
cyazofamid in food as follows:
i. Acute exposure. No acute toxicity
endpoint was identified for cyazofamid
for the general population including
infants and children, because no acute
effects were observed which could be
attributed to a single-dose exposure.
Nevertheless, EPA estimated acute
exposure for the subpopulation, females
13–49 years, based on the
developmental toxicity risk. In
estimating acute dietary exposure, EPA
used food consumption information
from the United States Department of
Agriculture (USDA) 1994–1996 and
1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII).
Tolerance level residues and 100
percent crop treated (PCT) assumptions
were used. Anticipated residues and
PCT information were not used.
ii. Chronic exposure. In conducting
the chronic dietary exposure assessment
EPA used the food consumption data
from the USDA 1994–1996 and 1998
CSFII. Tolerance level residues and 100
PCT assumptions were used.
Anticipated residues and PCT
information were not used.
iii. Cancer. Based on the data
summarized in Unit III.A., July 14, 2010,
and at https://www.regulation.gov in
document ‘‘Cyazofamid. Human Health
Risk Assessment for Proposed Section
18 Use on Basil, item 4.4 Dietary
Exposure and Risk,’’ p.14, EPA has
concluded that cyazofamid does not
pose a cancer risk to humans.
Cyazofamid has been classified as ‘‘not
likely to be carcinogenic in humans,’’
based on the absence of significant
tumor increases in two rodent
carcinogenic studies. Therefore, a
dietary exposure assessment for the
purpose of assessing cancer risk is
unnecessary.
2. Dietary exposure from drinking
water. The Agency used screening level
water exposure models in the dietary
exposure analysis and risk assessment
for cyazofamid in drinking water. These
simulation models take into account
data on the physical, chemical, and fate/
transport characteristics of cyazofamid.
Further information regarding EPA
drinking water models used in pesticide
exposure assessment can be found at
https://www.epa.gov/oppefed1/models/
water/index.htm.
Based on the Pesticide Root Zone
Model/Exposure Analysis Modeling
System (PRZM/EXAMS), the estimated
drinking water concentrations (EDWCs)
of cyazofamid for acute exposures are
estimated to be 136 parts per billion
VerDate Mar<15>2010
15:16 Jan 26, 2012
Jkt 226001
(ppb) for surface water and 2.18 ppb for
ground water. For chronic exposures for
non-cancer assessments EDWCs are
estimated to be 133 ppb for surface
water and 2.18 ppb for ground water.
Modeled estimates of drinking water
concentrations were directly entered
into the dietary exposure model. For
acute dietary risk assessment, the water
concentration value of 136 ppb was
used to assess the contribution to
drinking water. For chronic dietary risk
assessment, the water concentration of
value 133 ppb was used to assess the
contribution to drinking water.
3. Sources of 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).
Cyazofamid is currently registered for
the following uses that could result in
residential exposures: Commerciallytreated residential turf and ornamentals.
EPA assessed residential exposure using
the following assumptions: Nonoccupational handler exposures are not
expected; however, post-application
exposure is possible for children and
adults. Non-occupational/residential
MOEs were estimated for ‘‘Day 0’’
exposure. The post-application
children’s aggregate MOE (including
incidental oral exposures) is 1,600. The
Agency is concerned when MOEs are
<100. All MOEs, including the
children’s aggregate, are >100, and
therefore not a risk concern.
Further information regarding EPA
standard assumptions and generic
inputs for residential exposures may be
found at: https://www.epa.gov/
pesticides/trac/science/trac6a05.pdf.
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 cyazofamid to
share a common mechanism of toxicity
with any other substances, and
cyazofamid does not appear to produce
a toxic metabolite produced by other
substances. For the purposes of this
tolerance action, therefore, EPA has
assumed that cyazofamid does not have
a common mechanism of toxicity with
other substances. For information

which chemicals have a common
mechanism of toxicity and to evaluate

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
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 (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 toxicology
database for cyazofamid includes rat
and rabbit developmental toxicity
studies and a 2-generation reproduction
toxicity study in rats. There was some
evidence of increased susceptibility
following in utero exposure to rats in
the prenatal developmental toxicity
study; the increased incidence of bent
ribs in the high dose fetuses was
considered adverse and was used for
setting the developmental NOAEL/
LOAEL.
3. Conclusion. EPA has determined
that reliable data show that the safety of
infants and children would be
adequately protected if the FQPA SF
were reduced to 1X. That decision is
based on the following findings:
i. The toxicity database for
cyazofamid is sufficient to characterize
the hazard, to conduct FQPA
assessment, and to select toxicity
endpoints for risk assessment. Under
current data requirement guidelines,
functional immunotoxicity data (OPPTS
780.7800) is a data gap. However, the
cyazofamid toxicology database does
not show any evidence of biologically
relevant effects on the immune system
that relate to this chemical. The Agency
does not believe that conducting a
functional immunotoxicity study will
result in a lower NOAEL than the
regulatory dose for this risk assessment,
and an additional uncertainty factor
(UF) for the data gap is unnecessary.
ii. There is no indication that
cyazofamid is a neurotoxic chemical
and there is no need for a
developmental neurotoxicity study or
additional UFs to account for
E:\FR\FM\27JAR1.SGM
27JAR1
Federal Register / Vol. 77, No. 18 / Friday, January 27, 2012 / Rules and Regulations
pmangrum on DSK3VPTVN1PROD with RULES
neurotoxicity for this time-limited
tolerance.
iii. There was some evidence of
increased susceptibility following in
utero exposure to rats in the prenatal
developmental toxicity study. As
described earlier, the increased
incidence of bent ribs in the high dose
fetuses was considered adverse and was
used for setting the developmental
NOAEL/LOAEL. EPA considers this
approach conservative and highly
protective because bent ribs are a
reversible developmental anomaly
rather than a malformation.
iv. There are no residual uncertainties
identified in the exposure databases.
The dietary food exposure assessments
were performed based on 100 PCT and
tolerance-level residues. EPA made
conservative (protective) assumptions in
the ground and surface water modeling
used to assess exposure to cyazofamid
in drinking water. EPA used similarly
conservative assumptions to assess postapplication exposure of children as well
as incidental oral exposure of toddlers.
These assessments will not
underestimate the exposure and risks
posed by cyazofamid.
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 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
cyazofamid will occupy 1.2% of the
aPAD for females 13–49 years, the only
subpopulation assessed. For the
population of concern, the acute dietary
(food and drinking water) risk
assessment represents acute aggregate
risk.
2. Chronic risk. Using the exposure
assumptions described in this unit for
chronic exposure, EPA has concluded
that chronic exposure to cyazofamid
from food and water will utilize <1% of
the cPAD for children 1–2 years old, the
population group receiving the greatest
exposure. Based on the explanation in
Unit III.C.3. regarding residential use
patterns, chronic residential exposure to
residues of cyazofamid is not expected.
VerDate Mar<15>2010
15:16 Jan 26, 2012
Jkt 226001
3. Short-term and intermediate term
risk. Short-term and intermediate-term
risks have been assessed together
because both scenarios have the same
endpoints and PODs. Short-intermediate
term aggregate exposure takes into
account short-intermediate term
residential exposure plus chronic
exposure to food and drinking water
(considered to be a background
exposure level). Cyazofamid is currently
registered for uses that could result in
short-term and/or intermediate term
residential exposure, and the Agency
has determined that it is appropriate to
aggregate chronic exposure through food
and water with short-intermediate term
residential exposures to cyazofamid.
Using the exposure assumptions
described in this unit for shortintermediate term exposures, EPA has
concluded the combined shortintermediate term food, water, and
residential exposures result in aggregate
MOEs of >100 for all scenarios. Because
EPA’s level of concern for cyazofamid is
a MOE of 100 or below, these MOEs are
not of concern.
4. Aggregate cancer risk for U.S.
population. Based on the lack of
evidence of carcinogenicity in two
adequate rodent (both the rat and the
mouse) carcinogenicity studies,
cyazofamid 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 cyazofamid
residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies
are available to enforce the tolerance
expression. Cyazofamid its and
metabolite CCIM are completely
recovered (≤80% recovery) using FDA’s
Multiresidue Protocol D (without
cleanup). In addition, an acceptable
high performance liquid
chromatography/ultraviolet/detector
(HPLC/UV) method (‘‘Independent
Laboratory Validation of the Residue
Method for IKF–916 and CCIM in
Tomatoes’’, Document Number 013033–
0, Pyxant Labs Inc., with slight
modification) is available for use as a
single analyte confirmatory method.

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 U.N.
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 cyazofamid on basil.
VI. Conclusion
Therefore, time-limited tolerances are
established for residues of cyazofamid,
4-chloro-2-cyano-N,N-dimethyl-5-(4methylphenyl)-1H-imidazole-1sulfonamide,and its metabolites and
degradates in or on basil, fresh, at 12
ppm, and basil, dried, at 144 ppm.
These tolerances expire on December
31, 2014.
VII. Statutory and Executive Order
Reviews
This final rule establishes timelimited tolerances under sections 408(e)
and 408(l)(6) of FFDCA. The Office of
Management and Budget (OMB) has
exempted these types of actions from
review under Executive Order 12866,
entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993).
Because this final rule has been
exempted from review under Executive
Order 12866, this final rule is not
subject to Executive Order 13211,
entitled Actions Concerning Regulations
That Significantly Affect Energy Supply,

This final rule does not contain any
information collections subject to OMB
approval under the Paperwork

Since tolerances and exemptions that
are established in accordance with
sections 408(e) and 408(l)(6) of FFDCA,
such as the tolerances in this final rule,
do not require the issuance of a
proposed rule, the requirements of the
Regulatory Flexibility Act (RFA) (5
U.S.C. 601 et seq.) do not apply.
This final rule directly regulates
growers, food processors, food handlers,
and food retailers, not States or tribes,
nor does this action alter the
relationships or distribution of power
and responsibilities established by
Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such,
the Agency has determined that this
action will not have a substantial direct
effect on States or tribal governments,
on the relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled

II. Background and Statutory Findings
EPA, on its own initiative, in accordance with sections 408(e) and
408(l)(6) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21
U.S.C. 346a(e) and 346a(1)(6), is establishing time-limited tolerances
for combined residues of the fungicide cyazofamid, in or on fresh basil
at 12 parts per million (ppm), and on dried basil at 144 ppm. These
time-limited tolerances expire on December 31, 2014.
[[Page 4249]]
Section 408(l)(6) of FFDCA requires EPA to establish a time-limited
tolerance or exemption from the requirement for a tolerance for
pesticide chemical residues in food that will result from the use of a
pesticide under an emergency exemption granted by EPA under section 18
of FIFRA. Such tolerances can be established without providing notice
or period for public comment. EPA does not intend for its actions on
FIFRA section 18 related time-limited tolerances to set binding
precedents for the application of section 408 of FFDCA 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 Cyazofamid on Basil and FFDCA Tolerances
The Illinois Department of Agriculture (IDA) submitted a Section 18
Specific Exemption request (10IL02). 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
were met. EPA has authorized a specific exemption under FIFRA section
18 for the use of cyazofamid on basil for control of downy mildew
(Peronospora balbahrii) in Illinois. This new food use for cyazofamid
triggered the requirement for the establishment of tolerances under
FFDCA.
As part of its evaluation of the emergency exemption application,
EPA assessed the potential risks presented by residues of cyazofamid in
or on basil. In doing so, EPA considered the safety standard in section
408(b)(2) of FFDCA, and EPA decided that the necessary tolerance under
section 408(l)(6) of FFDCA would be consistent with the safety standard
and with FIFRA section 18. Consistent with the need to move quickly on
the emergency exemption in order to address an urgent non-routine
situation and to ensure that the resulting food is safe and lawful, EPA
is issuing this tolerance without notice and opportunity for public
comment as provided in section 408(l)(6) of FFDCA. Although these time-
limited tolerances expire on December 31, 2014, under section 408(l)(5)
of FFDCA, residues of the pesticide not in excess of the amounts
specified in the tolerance remaining in or on basil 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
cyazofamid meets FIFRA's registration requirements for use on basil 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 cyazofamid 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 Illinois 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 cyazofamid, 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 combined residues of cyazofamid on
fresh basil at 12 ppm, and on dried basil at 144 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/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for cyazofamid used for
human risk assessment is discussed in Unit III. B. of the final rule
published in the Federal Register of July 14, 2010 (75 FR 40745) (FRL-
8833-1).
B. Exposure Assessment
1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to cyazofamid, EPA considered exposure under the time-
[[Page 4250]]
limited tolerances established by this action as well as all existing
cyazofamid tolerances in 40 CFR 180.601. EPA assessed dietary exposures
from cyazofamid in food as follows:
i. Acute exposure. No acute toxicity endpoint was identified for
cyazofamid for the general population including infants and children,
because no acute effects were observed which could be attributed to a
single-dose exposure. Nevertheless, EPA estimated acute exposure for
the subpopulation, females 13-49 years, based on the developmental
toxicity risk. In estimating acute dietary exposure, EPA used food
consumption information from the United States Department of
Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of
Food Intake by Individuals (CSFII). Tolerance level residues and 100
percent crop treated (PCT) assumptions were used. Anticipated residues
and PCT information were not used.
ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the USDA 1994-1996
and 1998 CSFII. Tolerance level residues and 100 PCT assumptions were
used. Anticipated residues and PCT information were not used.
iii. Cancer. Based on the data summarized in Unit III.A., July 14,
2010, and at https://www.regulation.gov in document ``Cyazofamid. Human
Health Risk Assessment for Proposed Section 18 Use on Basil, item 4.4
Dietary Exposure and Risk,'' p.14, EPA has concluded that cyazofamid
does not pose a cancer risk to humans. Cyazofamid has been classified
as ``not likely to be carcinogenic in humans,'' based on the absence of
significant tumor increases in two rodent carcinogenic studies.
Therefore, a dietary exposure assessment for the purpose of assessing
cancer risk is unnecessary.
2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for cyazofamid in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of cyazofamid. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at https://www.epa.gov/oppefed1/models/water/index.htm.
Based on the Pesticide Root Zone Model/Exposure Analysis Modeling
System (PRZM/EXAMS), the estimated drinking water concentrations
(EDWCs) of cyazofamid for acute exposures are estimated to be 136 parts
per billion (ppb) for surface water and 2.18 ppb for ground water. For
chronic exposures for non-cancer assessments EDWCs are estimated to be
133 ppb for surface water and 2.18 ppb for ground water.
Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For acute dietary risk
assessment, the water concentration value of 136 ppb was used to assess
the contribution to drinking water. For chronic dietary risk
assessment, the water concentration of value 133 ppb was used to assess
the contribution to drinking water.
3. Sources of 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).
Cyazofamid is currently registered for the following uses that
could result in residential exposures: Commercially-treated residential
turf and ornamentals. EPA assessed residential exposure using the
following assumptions: Non-occupational handler exposures are not
expected; however, post-application exposure is possible for children
and adults. Non-occupational/residential MOEs were estimated for ``Day
0'' exposure. The post-application children's aggregate MOE (including
incidental oral exposures) is 1,600. The Agency is concerned when MOEs
are <100. All MOEs, including the children's aggregate, are >100, and
therefore not a risk concern.
Further information regarding EPA standard assumptions and generic
inputs for residential exposures may be found at: https://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
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 cyazofamid to share a common mechanism of
toxicity with any other substances, and cyazofamid does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
cyazofamid 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 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 (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
toxicology database for cyazofamid includes rat and rabbit
developmental toxicity studies and a 2-generation reproduction toxicity
study in rats. There was some evidence of increased susceptibility
following in utero exposure to rats in the prenatal developmental
toxicity study; the increased incidence of bent ribs in the high dose
fetuses was considered adverse and was used for setting the
developmental NOAEL/LOAEL.
3. Conclusion. EPA has determined that reliable data show that the
safety of infants and children would be adequately protected if the
FQPA SF were reduced to 1X. That decision is based on the following
findings:
i. The toxicity database for cyazofamid is sufficient to
characterize the hazard, to conduct FQPA assessment, and to select
toxicity endpoints for risk assessment. Under current data requirement
guidelines, functional immunotoxicity data (OPPTS 780.7800) is a data
gap. However, the cyazofamid toxicology database does not show any
evidence of biologically relevant effects on the immune system that
relate to this chemical. The Agency does not believe that conducting a
functional immunotoxicity study will result in a lower NOAEL than the
regulatory dose for this risk assessment, and an additional uncertainty
factor (UF) for the data gap is unnecessary.
ii. There is no indication that cyazofamid is a neurotoxic chemical
and there is no need for a developmental neurotoxicity study or
additional UFs to account for
[[Page 4251]]
neurotoxicity for this time-limited tolerance.
iii. There was some evidence of increased susceptibility following
in utero exposure to rats in the prenatal developmental toxicity study.
As described earlier, the increased incidence of bent ribs in the high
dose fetuses was considered adverse and was used for setting the
developmental NOAEL/LOAEL. EPA considers this approach conservative and
highly protective because bent ribs are a reversible developmental
anomaly rather than a malformation.
iv. There are no residual uncertainties identified in the exposure
databases. The dietary food exposure assessments were performed based
on 100 PCT and tolerance-level residues. EPA made conservative
(protective) assumptions in the ground and surface water modeling used
to assess exposure to cyazofamid in drinking water. EPA used similarly
conservative assumptions to assess post-application exposure of
children as well as incidental oral exposure of toddlers. These
assessments will not underestimate the exposure and risks posed by
cyazofamid.
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 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 cyazofamid will occupy 1.2% of the aPAD for females 13-49 years, the
only subpopulation assessed. For the population of concern, the acute
dietary (food and drinking water) risk assessment represents acute
aggregate risk.
2. Chronic risk. Using the exposure assumptions described in this
unit for chronic exposure, EPA has concluded that chronic exposure to
cyazofamid from food and water will utilize <1% of the cPAD for
children 1-2 years old, the population group receiving the greatest
exposure. Based on the explanation in Unit III.C.3. regarding
residential use patterns, chronic residential exposure to residues of
cyazofamid is not expected.
3. Short-term and intermediate term risk. Short-term and
intermediate-term risks have been assessed together because both
scenarios have the same endpoints and PODs. Short-intermediate term
aggregate exposure takes into account short-intermediate term
residential exposure plus chronic exposure to food and drinking water
(considered to be a background exposure level). Cyazofamid is currently
registered for uses that could result in short-term and/or intermediate
term residential exposure, and the Agency has determined that it is
appropriate to aggregate chronic exposure through food and water with
short-intermediate term residential exposures to cyazofamid.
Using the exposure assumptions described in this unit for short-
intermediate term exposures, EPA has concluded the combined short-
intermediate term food, water, and residential exposures result in
aggregate MOEs of >100 for all scenarios. Because EPA's level of
concern for cyazofamid is a MOE of 100 or below, these MOEs are not of
concern.
4. Aggregate cancer risk for U.S. population. Based on the lack of
evidence of carcinogenicity in two adequate rodent (both the rat and
the mouse) carcinogenicity studies, cyazofamid 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 cyazofamid residues.
V. Other Considerations
A. Analytical Enforcement Methodology
Adequate enforcement methodologies are available to enforce the
tolerance expression. Cyazofamid its and metabolite CCIM are completely
recovered (>80% recovery) using FDA's Multiresidue Protocol D (without
cleanup). In addition, an acceptable high performance liquid
chromatography/ultraviolet/detector (HPLC/UV) method (``Independent
Laboratory Validation of the Residue Method for IKF-916 and CCIM in
Tomatoes'', Document Number 013033-0, Pyxant Labs Inc., with slight
modification) is available for use as a single analyte confirmatory
method.
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 U.N. 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 cyazofamid on basil.
VI. Conclusion
Therefore, time-limited tolerances are established for residues of
cyazofamid, 4-chloro-2-cyano-N,N-dimethyl-5-(4-methylphenyl)-1H-
imidazole-1-sulfonamide,and its metabolites and degradates in or on
basil, fresh, at 12 ppm, and basil, dried, at 144 ppm. These tolerances
expire on December 31, 2014.
VII. Statutory and Executive Order Reviews
This final rule establishes time-limited tolerances under sections
408(e) and 408(l)(6) of FFDCA. The Office of Management and Budget
(OMB) has exempted these types of actions from review under Executive
Order 12866, entitled Regulatory Planning and Review (58 FR 51735,
October 4, 1993). Because this final rule has been exempted from review
under Executive Order 12866, this final rule is not subject to
Executive Order 13211, 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
[[Page 4252]]
Populations (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established in accordance
with sections 408(e) and 408(l)(6) of FFDCA, such as the tolerances in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Pub. L. 104-4).
This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).
VIII. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C.
