II. Summary of Petitioned-For Tolerance

    In the Federal Register of May 20, 2015 (80 FR 28925) (FRL-9927-
39), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 
U.S.C. 346a(d)(3), announcing the filing of two pesticide petitions: 
One by ISK Biosciences Corporation, 7470 Auburn Road, Suite A, Concord, 
Ohio 44077 (PP 5F8352) that requested to establish tolerances in 40 CFR 
180.601 for residues of the fungicide cyazofamid and its metabolite (4-
chloro-5-(4-methylphenyl)-1H-imidazole-2-carbonitrile) in or on bulb 
vegetables (crop group 3-07) at 2.0 parts per million (ppm); and one by 
IR-4, 500 College Road East, Suite 201W, Princeton, NJ 08540 (PP 
5E8350) that requested to establish tolerances in 40 CFR 180.601 for 
residues of the fungicide cyazofamid in or on the herb subgroup 19A at 
90 ppm and also to remove the existing tolerances for residues of 
cyazofamid and its metabolite in or on basil, dried leaves at 90 ppm 
and basil, fresh leaves at 30 ppm upon approval of the herb subgroup 
19A tolerances. That document referenced summaries of the two petitions 
prepared by ISK Biosciences, the registrant, which is available in the 
docket, https://www.regulations.gov. There were no comments received in 
response to the notices of filing.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Consistent with FFDCA section 408(b)(2)(D), and 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 for cyazofamid including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with cyazofamid follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered its 
validity, completeness, and reliability as well as the relationship of 
the results of the studies to human risk. EPA has also considered 
available information concerning the variability of the sensitivities 
of major identifiable subgroups of consumers, including infants and 
children.
    The target organ for cyazofamid in rats is the kidney, with an 
increased incidence of basophilic tubules, increased urinary volume, 
pH, and protein noted in male rats after subchronic exposure. Female 
rats were less sensitive, with only a marginal increase in urinary 
volume, and pH. These findings were noted in a 90-day oral toxicity 
study, and similar findings were noted in the 28-day oral toxicity 
range-finding study in rats. In the two-generation reproductive study 
in rats, there was an increased incidence of inflammation and 
nephropathy in the high-dose male rats as compared to the controls. 
Basophilic tubules are indicative of a regenerative process, but they 
can be more difficult to identify in older animals (i.e., tubular 
basophilia can be obscured by nephropathy or included as part of the 
nephropathy constellation). No kidney effects were observed in the 
chronic oral toxicity study in rats; however, this study did not test 
up to doses as high as those eliciting kidney effects in the subchronic 
and two-generation reproduction toxicity studies. The only relevant 
finding in the dog was an incidence of parathyroid cysts in males at 
the limit dose in the chronic study.
    The pre- and post-natal toxicology database for cyazofamid includes 
rat and rabbit developmental toxicity studies and a two-generation 
reproduction toxicity study in rats. The prenatal developmental study 
in rats showed evidence of increased quantitative susceptibility 
following in utero exposure as a marginally increased incidence of bent 
ribs was noted in fetuses at the limit dose, whereas no maternal 
toxicity was noted.
    No adverse effects were seen in a route-specific dermal toxicity 
study. Skin lesions were observed in males following oral exposure in 
the mouse carcinogenicity study, and are thought to be caused by an 
allergic reaction to systemic exposure because they did not occur 
following exposure via the dermal route. Cyazofamid is classified as 
``not likely to be carcinogenic to humans'' based on the lack of 
evidence for carcinogenicity in mice and rats and a lack of mutagenic 
potential.

    Specific information on the studies received and the nature of the 
adverse effects caused by cyazofamid as well as the no-observed-
adverse-effect-level (NOAEL) and the lowest-observed-adverse-effect-
level (LOAEL) from the toxicity studies can be found at https://www.regulations.gov in the document titled, ``Cyazofamid. Human Health 
Risk Assessment for Proposed New Uses on Use on Crop Subgroup 19A, 
Peppers and Tomatoes Grown in Greenhouses, and on Bulb Vegetables Crop 
Group 03-07'' on pp. 32 in docket ID number EPA-HQ-OPP-2015-0263.

B. 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 the NOAEL and the LOAEL are identified. 
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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for cyazofamid used for 
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to cyazofamid, EPA considered exposure under the petitioned-
for tolerances 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. Quantitative acute dietary exposure and risk 
assessments are performed for a food-use pesticide, if a toxicological 
study has indicated the possibility of an effect of concern occurring 
as a result of a 1-day or single exposure. No such effects were 
identified in the toxicological studies for cyazofamid; therefore, a 
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the U.S. Department 
of Agriculture's (USDA's) National Health and Nutrition Examination 
Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in 
food, EPA assumed tolerance-level residues and 100 percent crop treated 
(PCT) for all commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that cyazofamid does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    iv. Anticipated residue and PCT information. EPA did not use 
anticipated residue or PCT information in the dietary assessment for 
cyazofamid. Tolerance-level residues and 100 PCT were assumed for all 
food commodities.
    2. Dietary exposure from drinking water. Available environmental 
fate studies suggest cyazofamid is not very

[[Page 5603]]

mobile and quickly degrades into a number of degradation products under 
different environmental conditions. The highest estimated chronic 
drinking water concentrations resulted from modeling which assumed 
application of 100% molar conversion of the parent into the terminal 
degradate CTCA. EPA used these estimates of CTCA (4-chloro-5-p-
tolylimidazole-2-carboxylic acid) in its dietary exposure assessments, 
a conservative approach that likely overestimates the exposure 
contribution from drinking water.
    The Agency used screening-level water exposure models in the 
dietary exposure analysis and risk assessment for cyazofamid and its 
degradates in drinking water. These simulation models take into account 
data on the physical, chemical, and fate/transport characteristics of 
cyazofamid and its degradates. Further information regarding EPA 
drinking water models used in pesticide exposure assessment can be 
found at https://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM 
GW), the estimated drinking water concentrations (EDWCs) of the 
degradate CTCA for chronic exposures are estimated to be 133.5 parts 
per billion (ppb) for surface water and 211 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For chronic dietary risk 
assessment, the water concentration of value 211 ppb was used to assess 
the contribution to drinking water.
    3. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., for lawn and garden pest control, indoor pest control, 
termiticide, and flea and tick control on pets).
    Cyazofamid is currently registered for use on turf at golf courses, 
sod farms, seed farms, college and professional sports fields, 
residential and commercial lawns, and on ornamental plants in 
landscapes and those grown in commercial greenhouses and nurseries. EPA 
assessed residential exposure using the following scenarios:
     Adult handlers. The worst-case scenario was determined to 
be short-term inhalation exposures from mixing, loading, and applying 
cyazofamid to turf; and
     Children. The worst-case scenario was determined to be 
short-term post-application incidental oral exposure from hand-to-mouth 
activities on turf.
    Further information regarding EPA standard assumptions and generic 
inputs for residential exposures may be found at https://www2.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 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://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. 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 Safety Factor (FQPA SF). In applying this provision, EPA 
either retains the default value of 10X, or uses a different additional 
safety factor when reliable data available to EPA support the choice of 
a different factor.
    2. Prenatal and postnatal sensitivity. The developmental rabbit and 
two-generation reproduction toxicity study in rats did not show any 
evidence of increased susceptibility developmental or offspring, 
respectively. However, there was increased quantitative susceptibility 
in the rat developmental study; concentrations up to the limit dose did 
not cause maternal systemic toxicity, but there was an increased 
incidence of bent ribs. Concern is low based on the following: (1) The 
increase was marginal, (2) bent ribs are considered a variation rather 
than a malformation, (3) the effect was only seen at the limit dose, 
(4) there is a clear NOAEL for the effect, and (5) the selected 
endpoints address any concerns for this effect.
    3. Conclusion. EPA has determined that reliable data show 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 complete.
    ii. There is no indication that cyazofamid is a neurotoxic chemical 
and there is no need for a developmental neurotoxicity study or 
additional uncertainty factors (UFs) to account for neurotoxicity.
    iii. As noted in Section D.2., there was increased quantitative 
susceptibility in the rat developmental study, however, concern is low 
due to the reasons cited.
    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 and its degradates 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.

E. 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 effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was

[[Page 5604]]

selected. Therefore, cyazofamid 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 
cyazofamid from food and water will utilize 2% 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 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). Cyazofamid is 
currently registered for uses that could result in short-term 
residential exposure, and the Agency has determined that it is 
appropriate to aggregate chronic exposure through food and water with 
short-term residential exposures to cyazofamid.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 14,000 for adults 
and 6,100 for children 1-2 years old. Because EPA's level of concern 
for cyazofamid is a MOE of 100 or below, these MOEs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level).
    An intermediate-term adverse effect was identified; however, 
cyazofamid is not registered for any use patterns that would result in 
intermediate-term residential exposure. Intermediate-term risk is 
assessed based on intermediate-term residential exposure plus chronic 
dietary exposure. Because there is no intermediate-term residential 
exposure and chronic dietary exposure has already been assessed under 
the appropriately protective cPAD (which is at least as protective as 
the POD used to assess intermediate-term risk), no further assessment 
of intermediate-term risk is necessary, and EPA relies on the chronic 
dietary risk assessment for evaluating intermediate-term risk for 
cyazofamid.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, cyazofamid is not expected to pose a cancer risk to humans.
    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 cyazofamid residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    An enforcement method for non-fatty commodities is available, FDA's 
Multi-residue Protocol D (without cleanup). The method completely 
recovers (>80% recovery) cyazofamid and its metabolite (4-chloro-5-(4-
methylphenyl)-1H-imidazole-2-carbonitrile). In addition, the high-
performance liquid chromatography method with ultraviolent light 
detection (HPLC/UV) method is acceptable for use as a single analyte 
enforcement method provided a confirmatory method such as the liquid 
chromatography method with tandem mass-spectrometric detection (LC/MS/
MS) method is used.
    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 Aliment-arius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Aliment-arius 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.
    There are no Codex MRLs established for cyazofamid in/on the 
commodities included in this action.

V. Conclusion

    Therefore, tolerances are established for residues of cyazofamid 
(4-chloro-2-cyano-N,N-dimethyl-5-(4-methylphenyl)-1H-imidazole-1-
sulfonamide) and is metabolite (4-chloro-5-(4-methylphenyl)-1H-
imidazole-2-carbonitrile) in or on the herb subgroup 19A at 90 ppm; and 
bulb vegetables, group 3-07 at 2.0 ppm. In addition, the existing 
tolerances for residues of cyazofamid and its metabolite (4-chloro-5-
(4-methylphenyl)-1H-imidazole-2-carbonitrile) in or on basil, dried 
leaves and basil, fresh leaves are removed as unnecessary.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances 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) 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 on the basis 
of a petition under FFDCA section 408(d), 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

[[Page 5605]]

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. 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).
