Summary of Petitioned-For Tolerance
In the Federal Register of May 23, 2014 (79 FR 29731) (FRL-9910-
29), 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 3F8164) by Gowan Company, P.O. Box 5569, Yuma, AZ 85366. The petition requested that 40 CFR 180.567 be amended by establishing tolerances for residues of the fungicide zoxamide, 3, 5-dichloro-N-(3-chloro-1-ethyl-
1-methyl-2-oxopropyl)-4-methylbenzamide, and its metabolites 3,5-
dichloro-1,4-benzenedicarboxylic acid (RH-1455 and RH-141455) and 3,5-
dichloro-4-hydroxymethylbenzoic acid (RH-1452 and RH-141452) calculated as the stoichiometric equivalent of zoxamide, in or on onion, bulb, subgroup 3-07A at 0.7 parts per million (ppm). That document referenced a summary of the petition prepared by Gowan Company, the registrant, which is available in the docket, http://www.regulations.gov. 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, EPA is establishing the tolerance as requested but revising the tolerance expressions for zoxamide. The reason for these changes are explained in Unit IV.D.
-
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
Page 41912
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 zoxamide including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with zoxamide follows.
-
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 toxicity data of zoxamide indicate that the primary target organ is the liver. Liver and thyroid weights increased along with liver histopathological change and increases in alkaline phosphatase. Systemic toxicity was not observed in the 28-day rat dermal toxicity study up to the limit dose (1,000 milligram/kilogram/day (mg/kg/day)). There are no concerns for neurotoxicity, immunotoxicity, developmental toxicity, or reproductive toxicity. There was no evidence of increased susceptibility (quantitative or qualitative) for the offspring in the reproduction studies or for fetuses following in utero exposure in the developmental studies. Zoxamide is classified as ``not likely to be carcinogenic to humans'' based on the lack of treatment-related tumors in acceptable/guideline carcinogenicity studies in rats and mice.
Specific information on the studies received and the nature of the adverse effects caused by zoxamide 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 http://www.regulations.gov in document Zoxamide. Health Risk Assessment for the Proposed New Use on Bulb Onions (Crop Subgroup 3-07A) in docket ID number EPA-HQ-OPP-2013-0644.
-
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 http://www.epa.gov/pesticides/factsheets/riskassess.htm.
A summary of the toxicological endpoints for zoxamide used for human risk assessment is shown in the Table of this unit.

Exposure Assessment
-
Dietary exposure from food and feed uses. In evaluating dietary exposure to zoxamide, EPA considered exposure under the petitioned-for tolerances as well as all existing zoxamide tolerances in 40 CFR 180.567. EPA assessed dietary exposures from zoxamide in food as follows:
Page 41913
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 zoxamide; 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 assumed tolerance-level residues, 100% crop treated (CT), and default processing factors from the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCID) Version 7.81 (except for grape, raisin and potato granules/flakes).
iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that zoxamide does not pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary.
-
Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for zoxamide in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of zoxamide. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www.epa.gov/oppefed1/models/water/index.htm.
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 zoxamide for chronic exposures (non-cancer) are estimated to be 0.81 parts per billion (ppb) for surface water and 65.8 ppb for ground water, respectively.
Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For chronic dietary risk assessment, the water concentration of value 65.8 ppb was used to assess the contribution to drinking water.
-
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).
Zoxamide is not registered for any specific use patterns that would result in residential exposure.
-
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 zoxamide to share a common mechanism of toxicity with any other substances, and zoxamide does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that zoxamide 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 http://www.epa.gov/pesticides/cumulative.
-
-
Safety Factor for Infants and Children
-
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.
-
Prenatal and postnatal sensitivity. The prenatal and postnatal toxicity studies include rat and rabbit prenatal developmental studies in addition to a reproduction and fertility effects study in rats; and the highest doses used in these studies are at or above the limit dose. In the developmental studies, maternal and fetal toxicity was not observed up to the limit dose (1,000 mg/kg/day). In the rat reproduction and fertility effects study, decreased body weights and body weight gains was observed in only the parental females at the highest dose tested. Therefore, EPA has concluded that there was no evidence of increased susceptibility (quantitative or qualitative) for the offspring in the reproduction studies or for fetuses following in utero exposure in the developmental studies.
-
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 zoxamide is complete.
ii. There is no indication that zoxamide is a neurotoxic chemical and there is no need for a developmental neurotoxicity study or additional UFs to account for neurotoxicity.
iii. There is no evidence that zoxamide results in increased susceptibility in in utero rats or rabbits in the prenatal developmental studies or in young rats in the 2-generation reproduction study.
iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100% CT and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to zoxamide in drinking water. These assessments will not underestimate the exposure and risks posed by zoxamide.
-
-
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.
-
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, zoxamide is not expected to pose an acute risk.
-
Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to zoxamide from food and water will utilize 4.8% of the cPAD for children 1 to 2 years old, the population group receiving the greatest
Page 41914
exposure. There are no residential uses for zoxamide.
-
Short-term and intermediate-term risk. Short-term and intermediate-term aggregate risk takes into account short-term and intermediate-term residential exposure, respectively, plus chronic exposure to food and water (considered to be a background exposure level).
Zoxamide is currently not registered for any use patterns that could result in short-term or intermediate-term residential exposure. Because short- or intermediate-term residential exposure and chronic dietary exposure have already been assessed under the appropriately protective cPAD (which is at least as protective as the POD used to assess short-term risk), further assessment of short- and intermediate-
term risk is not necessary. EPA relies on the chronic dietary risk assessment for evaluating short- and intermediate-term risk for zoxamide.
-
Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, zoxamide is not expected to pose a cancer risk to humans.
-
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 zoxamide residues.

Analytical Enforcement Methodology
Adequate enforcement methodology (gas chromatography with electron capture detection (GC/ECD) and GC with mass selective detection (GC/
MSD)) is available to enforce the tolerance expression.
The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; email address: residuemethods@epa.gov.
-
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.
Neither Codex, Canada, nor Mexico has not established a MRL for zoxamide in/on bulb onions, so there will be no need to harmonize the international standards.
-
Response to Comments
One comment was received in response to the notice of filing of Gowan Company's application. The commenter objected to the increase of chemical residues generally and expressed concerns about the carcinogenic effects of chemicals in general on humans. The Agency understands the commenter's concerns regarding toxic chemicals and their potential effects on humans. Pursuant to its authority under the FFDCA, and as discussed further in this preamble, EPA conducted a comprehensive assessment of zoxamide, which included an assessment on the carcinogenic potential of zoxamide. Based on its assessment of the available data, the Agency has concluded that zoxamide is not likely to be a carcinogen and that there is a reasonable certainty that no harm will result from aggregate exposure to residues of zoxamide.
-
Revisions to Petitioned-For Tolerances
EPA is revising the tolerance expressions to clarify:
-
That, as provided in FFDCA section 408(a)(3), the tolerance covers metabolites and degradates of Zoxamide not specifically mentioned; and
-
That compliance with the specified tolerance levels is to be determined by measuring only the specific compounds mentioned in the tolerance expression.
-
-
-
Conclusion
Therefore, tolerances are established for residues of zoxamide, 3, 5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-4-methylbenzamide and its metabolites 3,5-dichloro-1,4-benzenedicarboxylic acid (RH-1455 and RH-141455) and 3,5-dichloro-4-hydroxymethylbenzoic acid (RH-1452 and RH-141452) calculated as the stoichiometric equivalent of zoxamide, in or on onion, bulb, subgroup 3-07A at 0.7 ppm.
In addition, EPA is revising the tolerance expressions for zoxamide contained in paragraphs (a)(1) and (a)(2), and in paragraph (b), removing the commodity ginseng, and reserving paragraph (b).
-
Statutory and Executive Order Reviews
This final rule establishes a tolerance under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ``Regulatory Planning and Review'' (58 FR 51735, October 4, 1993). Because this final rule has been exempted from review under Executive Order 12866, this final rule is not subject to Executive Order 13211, entitled ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997). This final rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ``Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations'' (59 FR 7629, February 16, 1994).
Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), do not apply.
This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled ``Consultation and Coordination with Indian Tribal Governments'' (65 FR
Page 41915
67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (2 U.S.C. 1501 et seq.).
This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA) (15 U.S.C. 272 note).
-
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).
