II. Summary of Petitioned-For Tolerance

In the Federal Register of May 9, 2019 (84 FR 20320) (FRL-9992-36), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 8E8718) by IR-4, Rutgers, The State University of New Jersey, 500 College Road East, Suite 201 W, Princeton, New Jersey 08540. The petition requested that 40 CFR 180.601 be amended by establishing tolerances for residues of the fungicide cyazofamid, 4-chloro-2-cyano-N,N-dimethyl-5-(4-methylphenyl)-1 H-imidazole-1-sulfonamide, in or on brassica, leafy greens, subgroup 4-16B at 15.0 parts per million (ppm); ginseng at 0.2 ppm; kohlrabi at 1.5 ppm; leafy greens subgroup 4-16A at 10.0 ppm; and vegetable, brassica, head and stem, group 5-16 at 1.5 ppm. Upon the establishment of those tolerances, the petition requested the removal of existing tolerances for residues of the fungicide cyazofamid in or on brassica, head and stem, subgroup 5A at 1.2 ppm; brassica, leafy greens, subgroup 5B at 12.0 ppm; leafy greens subgroup 4A at 10 ppm; and turnip, greens at 12.0 ppm. That document referenced a summary of the petition prepared by ISK Biosciences Corporation, the registrant, which is available in the docket, Two comments were received on the notice of filing. EPA's response to these comments is discussed in Unit IV.C.

Based upon review of the data supporting the petition and pursuant to its authority in FFDCA section 408(d)(4)(A)(i), EPA is establishing three of the tolerances at a different level than requested. The reasons for these changes are explained in Unit IV.D.

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 Start Printed Page 15388pesticide 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.

Cyazofamid belongs to a chemical class based on the cyanoimidazole and sulfonamide moieties. It specifically interferes with the cytochrome bc1 complex (ubiquinol cytochrome c oxidoreductase) in the mitochondrial respiratory chain of oomycetes fungi. The mechanism of toxicity in mammals is not clear. There were no treatment-related adverse effects in the acute and subchronic neurotoxicity studies. However, following repeated administration in more than one species, toxicological effects were observed primarily in the kidney. There were no effects observed up to the limit dose (1,000 mg/kg) in the dermal toxicity study. In dogs, there were no major toxicity findings.

In the prenatal developmental toxicity study in rats, there was a marginal increased incidence of bent ribs observed in the high-dose (1,000 mg/kg/day) without any maternal effects, indicating quantitative susceptibility following in utero exposure.

Cyazofamid is classified as “not likely to be carcinogenic to humans” based on the lack of evidence of carcinogenicity in both the rat and the mouse studies. Additionally, cyazofamid does not appear to be mutagenic, based on several negative in vivo and in vitro studies.

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 in document “Cyazofamid. Human Health Risk Assessment for New Uses of Cyazofamid on Ginseng, and Greenhouse Cucumbers and Crop Group Conversions on Vegetable, Brassica, Head and Stem, Group 5-16; Brassica, Leafy Greens, Subgroup 4-16B; Leafy Greens, Subgroup 4-16A; and to Establish an Individual Tolerance on Kohlrabi” on page 20 in docket ID number EPA-HQ-OPP-2018-0832.

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 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​pesticide-science-and-assessing-pesticide-risks.

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 February 3, 2016 (81 FR 5602) (FRL-9940-46).

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 USDA 2003-2008 National Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA). As to residue levels in food, EPA included tolerance-level residues for all crops, default processing factors and assumed that 100% of the crops were treated (100% CT) with cyazofamid.

iii. Cancer. Based on the data cited 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 percent crop treated (PCT) information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for cyazofamid. Tolerance-level residues and/or 100% CT were assumed for all food commodities.

2. Dietary exposure from drinking water. The Agency used screening-level water exposure models in the dietary exposure analysis and risk assessment for 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​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 cyazofamid for chronic exposures for non-cancer assessments are estimated to be 133.5 Start Printed Page 15389ppb 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 value of 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, termiticides, and flea and tick control on pets).

Cyazofamid is currently registered for the following uses that could result in residential exposures: Turf and ornamentals. EPA assumes there is no residential handler exposure because labels require users to wear personal protective equipment. Post application exposure (to turf and ornamental) from hand-to-mouth exposures was greatest to children 1 to less than 2 years old. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at​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.” Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to cyazofamid and any other substances and cyazofamid does not appear to produce a toxic metabolite produced by other substances. For the purposes of this action, therefore, EPA has not assumed that cyazofamid has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see EPA's website at​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 FQPA Safety Factor (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. In the prenatal developmental toxicity study in rats, there was a marginal increased incidence of bent ribs observed at the high-dose (1,000 mg/kg/day) without any maternal effects, indicating quantitative susceptibility following in utero exposure. There is low concern for this effect because (1) bent ribs are a developmental variation rather than a malformation; (2) the increased incidence was only marginally increased over historical and concurrent controls; (3) similar effects were not seen in the rabbit developmental study; and (4) the effect was only observed at the limit dose.

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 UFs to account for neurotoxicity.

iii. Although there is evidence of quantitative susceptibility in the developmental rat study, the concern is low because the effects occur at the limit dose and are well-characterized with clearly established no observed adverse-effect level (NOAEL)/lowest-observed adverse-effect level (LOAEL) values and selected endpoints address the observed effects.

iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100% CT, default processing factors and assumed tolerance-level residues for all crops. 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.

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 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 2.0% 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 6,200 for children 1 to less than 2 years old for dietary exposure (which is considered a background exposure) and incidental oral (hand-to-mouth) exposure from contact with Start Printed Page 15390treated turf. Because EPA's level of concern for cyazofamid is an 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

Adequate enforcement methods are available to determine residues of cyazofamid and its metabolite CCIM (4-chloro-5-(4-methylphenyl)-1 H-imidazole-2-carbonitrile) in various commodities. An enforcement method for non-fatty commodities is available, FDA's Multiresidue Protocol D (without cleanup). The method completely recovers cyazofamid and its metabolite CCIM. 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 methods 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:

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 established MRLs for cyazofamid in or on Brassica (cole or cabbage) vegetables, head cabbage, and flowerhead Brassicas at 1.5 ppm; leaves of Brassicaceae at 15 ppm; and leafy vegetables (except Brassica leafy vegetables) at 10 ppm. The U.S. tolerances being established are harmonized with these Codex MRLs, specifically vegetable, brassica, head and stem, group 5-16 at 1.5 ppm; kohlrabi at 1.5 ppm; brassica leafy greens, subgroup 4-16B at 15 ppm; and leafy greens subgroup 4-16A at 10 ppm. There is no Codex MRL for ginseng.

C. Response to Comments

EPA received two comments to the Notice of Filing, generally opposed to any cyazofamid residues on leafy greens. Although the Agency recognizes that some individuals believe that pesticides should be banned on agricultural crops, the existing legal framework provided by section 408 of the FFDCA states that tolerances may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. These comments appear to be directed at the underlying statute and not EPA's implementation of it; the comments provide no information relevant the Agency's safety determination.

D. Revisions to Petitioned-For Tolerances

EPA is establishing tolerances for Brassica, leafy greens, subgroup 4-16B and Leafy greens subgroup 4-16A at different levels than requested to be consistent with the Organisation for Economic Cooperation and Development (OECD) rounding class practice. For ginseng, the petitioner's proposed tolerance was adjusted because storage stability data indicated a decline in residues of CCIM. Organization for Economic Cooperation and Development (OECD) statistical calculation procedures applied to the corrected residue data provided a different value (0.3 ppm) than the proposed value (0.2 ppm). Therefore, EPA is establishing the tolerance for ginseng at 0.3 ppm.

V. Conclusion

Therefore, tolerances are established for residues of cyazofamid, 4-chloro-2-cyano-N,N-dimethyl-5-(4-methylphenyl)-1 H-imidazole-1-sulfonamide, in or on Brassica, leafy greens, subgroup 4-16B at 15 ppm; Ginseng at 0.3 ppm; Kohlrabi at 1.5 ppm; Leafy greens subgroup 4-16A at 10 ppm; and Vegetable, brassica, head and stem, group 5-16 at 1.5 ppm. Additionally, EPA is removing the established tolerances for Brassica, head and stem, subgroup 5A at 1.2 ppm; Brassica, leafy greens, subgroup 5B at 12.0 ppm; Leafy greens subgroup 4A at 10 ppm; and Turnip, greens at 12.0 ppm. Finally, as a housekeeping measure, EPA is removing the expired exemption in paragraph (b) Section 18 emergency exemptions for Basil, dried at 144 ppm, as it expired on December 31, 2014.

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), nor is it considered a regulatory action under Executive Order 13771, entitled “Reducing Regulations and Controlling Regulatory Costs,” (82 FR 9339, February 3, 2017). This action does not contain any information Start Printed Page 15391collections 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 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).
