In the Federal Register of August 19, 2009 (74 FR 41898) (FRL–8426–7), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 9F7549) by Gowan Company, 370 South Main Street, Yuma, AZ, 85364. The petition requested that 40 CFR 180.448 be amended by establishing tolerances for residues of the insecticide hexythiazox,trans-5-(4-chlorophenyl)-N-cyclohexyl4-methyl-2-oxothiazolidine-3- carboxamide and its metabolites containing the (4-chlorophenyl)-4- methyl-2-oxo-3-thiazolidine moiety (expressed as parts per million of the parent compound), in or on corn, sweet, kernel plus cob with husk removed at 0.1 parts per million (ppm); corn, sweet, forage at 3 ppm; bean, dried at 0.4 ppm; and bean, succulent at 0.4 ppm. That notice referenced a summary of the petition prepared by Gowan Company, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the notice of filing.

Based upon review of the data supporting the petition, EPA has revised the proposed tolerance levels for corn, sweet, forage; and bean, succulent to 4 ppm and 0.3 ppm, respectively. The


### 18896 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Rules and Regulations

reasons for these changes are explained in Unit IV.C. 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 section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of FFDCA, 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 hexythiazox including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with hexythiazox 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.

Hexythiazox has low acute toxicity by the oral, dermal and inhalation routes of exposure. It produces mild eye irritation, is not a dermal irritant, and is negative for dermal sensitization. Hexythiazox is not a developmental or reproductive toxicant. The toxicology database for hexythiazox provides no indication of increased susceptibility in rats or rabbits from in utero and postnatal exposure to hexythiazox. The database does not show any evidence of treatment-related effects on the nervous system or the immune system. Hexythiazox is classified as ‘‘likely to be carcinogenic to humans ’’ . EPA has determined that a non-quantitative risk assessment approach (i.e., nonlinear, reference dose (RfD) approach) was appropriate and protective of all chronic effects including potential carcinogenicity of hexythiazox.

Specific information on the studies received and the nature of the adverse effects caused by hexythiazox 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

‘‘Hexythiazox. Human Health Risk Assessment to Support New Uses on Sweet Corn, Dry Beans and Succulent Beans, ’’ page 24 in docket ID number EPA–HQ–OPP–2009–0325. 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 http:// www.epa.gov/pesticides/factsheets/ riskassess.htm.

A summary of the toxicological endpoints for hexythiazox used for human risk assessment can be found in the final rule published in the Federal Register of March 17, 2010 (Vol. 75 FR 12691) (FRL–8813–7), and at http:// www.regulations.gov in document

‘‘Hexythiazox. Human Health Risk Assessment to Support New Uses on Sweet Corn, Dry Beans and Succulent Beans, ’’ page 11 in docket ID number EPA–HQ–OPP–2009–0325.
C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to hexythiazox, EPA considered exposure under the petitioned-for tolerances as well as all existing hexythiazox tolerances in 40 CFR 180.448. EPA assessed dietary exposures from hexythiazox 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 hexythiazox; 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 1994–1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA used tolerance level residues, assumed 100 percent crop treated (PCT), and incorporated DEEM default processing factors.

iii. Cancer. EPA determines whether quantitative cancer exposure and riskassessments are appropriate for a fooduse pesticide based on the weight of the evidence from cancer studies and other relevant data. Cancer risk is quantified using a linear or nonlinear approach. If sufficient information on the carcinogenic mode of action is available, a threshold or nonlinear approach is used and a cancer RfD is calculated based on an earlier noncancer key event. If carcinogenic mode of action data are not available, or if the mode of action data determines a mutagenic mode of action, a default linear cancer slope factor approach is utilized. Based on the data in the Federal Register of March 17, 2010 (Vol. 75 FR 12691) (FRL–8813– 7), EPA has concluded that a nonlinear RfD approach is appropriate for assessing cancer risk to hexythiazox. Cancer risk was assessed using the same exposure estimates as discussed in Unit III.C.1.ii., chronic exposure.

iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for hexythiazox. Tolerance level residues and/or 100 PCT were assumed for all food commodities.

2. Dietary exposure from drinking

water. The Agency used screening level


### 18897 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Rules and Regulations

water exposure models in the dietary exposure analysis and risk assessment for hexythiazox in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of hexythiazox. 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), the estimated drinking water concentration (EDWC) of hexythiazox for chronic exposures for non-cancer and cancer assessments is estimated to be 4.5 ppb for surface water. Since surface water residue values greatly exceed groundwater EDWCs, surface water residues were used in the dietary risk assessment.

Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model.

3. From non-dietary exposure. The

term ‘‘residential exposure’’ is used inthis 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).

Hexythiazox is not currently registered for any specific use patterns that would result in residential exposure. However, the following uses that could result in residential exposures are pending registration in the near future and are included in this risk assessment: Turf, ornamental landscape plantings, ornamental plants, trees and vines in nurseries, residential fruit trees, nut trees, caneberries, and orchids.

Both adults and children may be exposed to hexythiazox residues from contact with treated lawns or treated plants. The exposure and risk assessment included risks to adult handlers from inhalation exposures. The exposure assessment for children included risks from incidental oral exposure resulting from transfer of residues from the hands or objects to the mouth, and from incidental ingestion of soil. Details of the residential exposure and risk assessment are contained in the final rule published in the Federal Register of July 14, 2010 (75 FR 40741), and at http://www.regulations.gov in document ‘‘Hexythiazox. Human Health Risk Assessment to Support New Uses on Sweet Corn, Dry Beans, and Succulent Beans, ’’ page 16 in docket ID number EPA–HQ–OPP–2009–0325.

Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at http://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 hexythiazox to share a common mechanism of toxicity with any other substances, and hexythiazox does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that hexythiazox 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. 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. The prenatal and postnatal toxicology data base indicates no increased susceptibility of rats or rabbits to in
utero and/or postnatal exposure to hexythiazox.

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 hexythiazox is incomplete under the new 40 CFR part 158 data requirements for conventional pesticides, which requires certain generic testing, including acute and subchronic neurotoxicity studies and an immunotoxicity study. However, the toxicology database does not show any evidence of treatment-related effects on the nervous system or the immune system. The overall weight of evidence suggests that this chemical does not directly target either system. Although acute and subchronic neurotoxicity studies and an immunotoxicity study are required as a part of new data requirements in the 40 CFR part 158 for conventional pesticide registrations, the Agency does not believe that conducting these studies will result in a lower POD than any currently used for risk assessment, and therefore, a database uncertainty factor (UF DB ) is not needed to account for the lack of these studies.

ii. There is no indication that hexythiazox 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 hexythiazox 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 PCT and tolerance-level residues. The dietary risk assessment is highly conservative and not expected to underestimate risk. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to hexythiazox 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 hexythiazox. 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


### 18898 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Rules and Regulations

a single oral exposure was identified and no acute dietary endpoint was selected. Therefore, hexythiazox 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 hexythiazox from food and water will utilize 51% of the cPAD for children 1–2 years of age, 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 hexythiazox 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).

There are potential short-term exposures from the pending residential uses for hexythiazox. The Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to hexythiazox.

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 15,000 for adults and 1,900 for children. Because EPA’s level of concern for hexythiazox 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).

There are potential intermediate-term exposures from the pending residential uses for hexythiazox. The Agency has determined that it is appropriate to aggregate chronic exposure through food and water with intermediate-term residential exposures to hexythiazox.

Using the exposure assumptionsdescribed in this unit for intermediateterm exposures, EPA has concluded that the combined intermediate-term food, water, and residential exposures result in aggregate MOEs of 15,000 for adults and 2,200 for children. Because EPA’s level of concern for Hexythiazox is a MOE of 100 or below, these MOEs are not of concern.

5. Aggregate cancer risk for U.S. population. As discussed in Unit III.C.1.iii, EPA concluded that regulation based on the chronic reference dose will be protective for both chronic and carcinogenic risks. As noted in this unit there are no chronic risks of concern.

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 hexythiazox residues.

IV. Other Considerations A. Analytical Enforcement Methodology

Adequate enforcement methodology (high performance liquid chromatography method with UV detection (HPLC/UV)) 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.

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.

A Codex MRL for common beans (pods and/or immature seeds) is currently established at 0.5 ppm. It is not possible to harmonize the U.S. tolerance with the Codex MRL since the Codex MRL is for parent compound only and the U.S. expression includes metabolites of concern. There are no Canadian or Mexican MRLs for beans and there is no Codex, Canadian or Mexican MRL for sweet corn commodities. C. Revisions to Petitioned for Tolerances

Based upon review of the data supporting the petition, EPA has revised the proposed tolerance levels for corn, sweet, forage; and bean, succulent to 4 ppm and 0.3 ppm, respectively. The tolerance spreadsheet in the Agency’s Guidance for Setting Pesticide Tolerances Based on Field Trial Data was used to determine appropriate tolerance levels for sweet corn forage, dried beans and succulent beans. The tolerance spreadsheet was not used for sweet corn kernel plus cob with husk removed (K+CWHR) because >65% of the residues were <LOQ. The data indicate that the proposed tolerance for sweet corn forage is too low, the recommended tolerance is 4.0. Additionally, the tolerance spreadsheet indicates that the proposed level of 0.4 ppm is too high for succulent beans. The tolerance should be set at 0.3 ppm.

V. Conclusion

Therefore, tolerances are established for residues of hexythiazox, trans-5-(4- chlorophenyl)-N-cyclohexyl-4-methyl-2- oxothiazolidine-3-carboxamide and its metabolites containing the (4- chlorophenyl)-4-methyl-2-oxo-3- thiazolidine moiety (expressed as parts per million of the parent compound), in or on corn, sweet, kernel plus cob with husk removed at 0.1 ppm; corn, sweet, forage at 4 ppm; bean, dried, seed at 0.4 ppm; and bean, succulent at 0.3 ppm. VI. Statutory and Executive Order Reviews

This final rule establishes tolerances under section 408(d) of FFDCA 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 section 408(d) of FFDCA, such as the tolerance in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory


### 18899 Federal Register / Vol. 76, No. 66 / Wednesday, April 6, 2011 / Rules and Regulations

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). VII. 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. 804(2). List of Subjects in 40 CFR Part 180
