II. Petition for Tolerance

In the Federal Register of August 19, 2009, (74 FR 41900) (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 8F7420) by BASF Corporation, P.O. Box 13528, Research Triangle Park, NC 27709-3528. The petition requested that 40 CFR 180.583 be amended by establishing tolerances for residues of the fungicide triticonazole, (1RS)-(E)-5-[(4-chlorophenyl)methylene]-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol, in or on grain, cereal, group 15, except rice, and grain, cereal, forage, fodder and straw, group 16, except rice, at 0.05 and 0.10 parts per million (ppm), respectively. That notice referenced a summary of the petition prepared by BASF Corporation, the registrant, which is available to the public 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 modified both the crop group terminology, and tolerance levels for grain, cereal, group 15, except rice, at 0.01 ppm, and the crop group terminology (only) for grain, cereal, forage, fodder and straw, group 16, except rice, at 0.10 ppm. These tolerances replace previously established individual tolerances for barley, grain; barley, hay; barley, straw; wheat, forage; wheat, grain; wheat, hay; and wheat, straw at 0.05 ppm. The reason for these changes is 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 the petitioned-for tolerances for residues of triticonazole, (1RS)-(E)-5-[(4-chlorophenyl)methylene]-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol on grain, cereal, group 15, except rice, at 0.01 ppm, and grain, cereal, forage, fodder and straw, group 16, except rice, at 0.10 ppm. EPA's assessment of exposures and risks associated with establishing tolerances 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.

Triticonazole has low acute toxicity, is not a skin, eye, or respiratory irritant, or a dermal sensitizer. Non-acute toxicity studies show that the liver (rat, mouse, dog) and adrenals (rat, dog, rabbit) are target organs across species. Adverse body weight changes (rat, dog, rabbit, mouse) and clinical signs (rat, dog, mouse) also were observed in multiple species. In the developmental and reproductive toxicity studies, adverse effects were seen at the same dose level in the offspring and parental animals, and the offspring were not qualitatively more susceptible compared with adults. In the rat subchronic study, decreased thymus weights were reported at a dose level (~2,300 milligrams/kilogram/day (mg/kg/day)) two times higher than the limit dose (1,000 mg/kg/day). Triticonazole was negative for mutagenicity, and the cancer classification is “Not Likely to Be Carcinogenic to Humans” based on a lack of evidence of carcinogenicity in the two guideline studies conducted on rats and mice.

Specific information on the studies received and the nature of the adverse effects caused by triticonazole 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 the document “Triticonazole. Human Health Risk Assessment for Proposed Seed Treatment Use on Cereal Grains (Crop Group 15) Including Barley, Field Corn, Oats, Popcorn, Rye, Sorghum Grain, Sweet Corn, Triticale, and Wheat (Excluding Rice); and Forage, Fodder, and Straw of Cereal Grains (Crop Group 16), Excluding Rice,” at pages 34 to 36 in docket ID number EPA-HQ-OPP-2009-0276.

B. Toxicological Endpoints

For hazards that have a threshold below which there is no appreciable risk, a toxicological point of departure (POD) is identified as the basis for derivation of reference values for risk assessment. The POD may be defined as the highest dose at which no adverse effects are observed (the NOAEL) in the toxicology study identified as appropriate for use in risk assessment. However, if a NOAEL cannot be determined, the lowest dose at which adverse effects of concern are identified (the LOAEL) or a benchmark dose (BMD) approach is sometimes used for risk assessment. Uncertainty/safety factors (UFs) are used in conjunction with the POD to take into account uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Safety is assessed for acute and chronic dietary risks by comparing aggregate food and water exposure to the pesticide to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD are calculated by dividing the POD by all applicable UFs. Aggregate short-, intermediate-, and chronic-term risks are evaluated by comparing food, water, and residential exposure to the POD to ensure that the margin of exposure (MOE) called for by the product of all applicable UFs is not exceeded. This latter value is referred to as the level of concern (LOC).

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 greater than that 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 triticonazole used for human risk assessment can be found at http://www.regulations.gov in the document “Triticonazole. Human Health Risk Assessment for Proposed Seed Treatment Use on Cereal Grains (Crop Group 15) Including Barley, Field Corn, Oats, Popcorn, Rye, Sorghum Grain, Sweet Corn, Triticale, and Wheat (Excluding Rice); and Forage, Fodder, and Straw of Cereal Grains (Crop Group 16), Excluding Rice,” at pages 15 to 16 in docket ID number EPA-HQ-OPP-2009-0276.

C. Exposure Assessment

1. Dietary exposure from food and feed uses. In evaluating dietary exposure to triticonazole, EPA considered exposure under the petitioned-for tolerances as well as all existing triticonazole tolerances in 40 CFR 180.583. EPA assessed dietary exposures from triticonazole 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.

In estimating acute dietary exposure, EPA used food consumption information from the U.S. Department of Agriculture (USDA) 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII). As to residue levels in food, EPA assumed tolerance level residues of triticonazole were found in all commodities and that all commodities consumed were 100% crop treated. Anticipated residues and/or percent crop treated (PCT) information were not used.

ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 1994-1996 and 1998 CSFII. As to residue levels in food, EPA assumed tolerance level residues in all commodities, and 100% crop treated for all treated commodities. Anticipated residues and/or PCT information were not used.

iii. Cancer. Triticonazole is classified as “not likely to be carcinogenic to humans” based on the absence of significant tumor increases in two adequate rodent carcinogenicity studies. There is no evidence that triticonazole is carcinogenic to humans, therefore an exposure assessment to evaluate cancer risk is not needed.

iv. Anticipated residue and percent crop treated (PCT) information. EPA did not use anticipated residue and/or PCT information in the dietary assessment for triticonazole. Tolerance level residues and/or 100% crop treated 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 triticonazole in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of triticonazole. 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.

The estimated drinking water concentrations (EDWCs) used in the dietary risk assessment were provided by OPP's Environmental Fate and Effects Division and incorporated directly into the dietary assessment. The EDWCs used in the dietary assessment were modeled using the surface water model, Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS). For the acute point estimate, the PRZM-EXAMS 1-in-10 year annual maximum EDWC was used. For the chronic point estimate, the PRZM-EXAMS 1-in-10 year annual mean EDWC was used. PRZM-EXAMS EDWCs were used because they were higher (and therefore more protective) than the groundwater model’s, (Screening Concentration in Groudwater model (SCI-GROW’s)) EDWC. Based on the PRZM/EXAMS, the EDWCs of triticonazole for acute exposures are 75.5 parts per billion (ppb) for surface water and 5.7 ppb for ground water, and chronic exposures for non-cancer assessments are estimated to be 32.8 ppb for surface water.

Modeled estimates of drinking water concentrations were directly entered into the dietary exposure model. For acute dietary risk assessment, the water concentration value of 75.5 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration value of 32.8 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). Triticonazole is currently registered for the following uses that could result in residential exposures: Residential and commercial turfgrass, golf courses, and sod farms. EPA quantitatively assessed the risk from residential exposure to children from children’s incidental oral post-application scenarios (hand to mouth, mouthing grass, and soil ingestion). Children and adults may also have post-application dermal exposure but dermal toxicity studies with triticonazole did not identify any adverse effects from such exposure.

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 triticonazole to share a common mechanism of toxicity with any other substances, and triticonazole does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has assumed that triticonazole 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 website at http://www.epa.gov/​pesticides/​cumulative.

Triticonazole is a member of the triazole-containing class of pesticides. Although conazoles act similarly in plants (fungi) by inhibiting ergosterol biosynthesis, there is not necessarily a relationship between their pesticidal activity and their mechanism of toxicity in mammals. Structural similarities do not constitute a common mechanism of toxicity. Evidence is needed to establish that the chemicals operate by the same, or essentially the same, sequence of major biochemical events. In conazoles, however, a variable pattern of toxicological responses is found. Some are hepatotoxic and hepatocarcinogenic in mice; some induce thyroid tumors in rats; and some induce developmental, reproductive, and neurological effects in rodents. Furthermore, the conazoles produce a diverse range of biochemical events including altered cholesterol levels, stress responses, and altered DNA methylation. It is not clearly understood whether these biochemical events are directly connected to their toxicological outcomes. Thus, there is currently no evidence to indicate that conazoles share common mechanisms of toxicity and EPA is not following a cumulative risk approach based on a common mechanism of toxicity for the conazoles. For information regarding EPA’s procedures for cumulating effects from substances found to have a common mechanism of toxicity, see EPA’s website at http://www.epa.gov/​pesticides/​cumulative.

Triticonazole and other triazole-containing pesticides can form the common metabolite 1,2,4-triazole and two triazole conjugates (triazolylalanine and triazolylacetic acid). To support existing tolerances and to establish new tolerances for triazole-derivative pesticides, including triticonazole, EPA conducted a human health risk assessment for exposure to 1,2,4-triazole, triazolylalanine, and triazolylacetic acid resulting from the use of all current and pending uses of any triazole-derived fungicide. The risk assessment is a highly conservative, screening-level evaluation in terms of hazards associated with common metabolites (e.g., use of a maximum combination of uncertainty factors) and potential dietary and non-dietary exposures (i.e., high end estimates of both dietary and non-dietary exposures). In addition, the Agency retained the additional 10X FQPA safety factor for the protection of infants and children. The assessment includes evaluations of risks for various subgroups, including those comprised of infants and children. The Agency’s complete risk assessment is found in the propiconazole reregistration docket at http://www.regulations.gov, Docket Identification (ID) Number EPA-HQ-OPP-2005-0497.

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 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 toxicity database for triticonazole includes rat and rabbit developmental toxicity studies and a two generation reproduction study in rats. There is no evidence of increased susceptibility following in utero and/or postnatal exposure in the developmental toxicity studies in rats or rabbits, and in the 2-generation rat reproduction study.

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 triticonazole is complete with the exception of a newly required immunotoxicity study. In accordance with 40 CFR Part 158 toxicity data requirements, an immunotoxicity study (Harmonized guideline 870.7800) is required for triticonazole. In the absence of specific immunotoxicity studies, EPA has evaluated the available triticonazole toxicity data to determine whether an additional uncertainty factor is needed to account for potential immunotoxicity. The toxicological database for triticonazole does not indicate that the immune system is the primary target organ. Decreased thymus weight was observed in only one species (rat) at the highest dose tested (~2x the limit dose of 1,000 mg/kg/day); these findings may be due to secondary effects of overt systemic toxicity. Based on this evidence, EPA does not believe that conducting immunotoxicity testing will result in a point of departure lower than those already selected for triticonazole risk assessment, and an additional uncertainty factor is not needed to account for potential immunotoxicity.

ii. There are no indications that triticonazole 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 triticonazole 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 database. The dietary food exposure assessments were performed based on 100% crop treated and tolerance-level residues. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to triticonazole in drinking water. EPA used similarly conservative assumptions to assess post-application exposure of children as well as incidental oral exposure of toddlers.

E. Aggregate Risks and Determination of Safety

EPA determines whether acute and chronic pesticide exposures are safe by comparing aggregate exposure estimates to the acute population adjusted dose (aPAD) and chronic population adjusted dose (cPAD). The aPAD and cPAD represent the highest safe exposures, taking into account all appropriate SFs. EPA calculates the aPAD and cPAD by dividing the POD by all applicable UFs. For linear cancer risks, EPA calculates the probability of additional cancer cases 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 POD to ensure that the MOE called for by the product of all applicable UFs is not exceeded.

1. Acute risk. Using the exposure assumptions discussed in this unit for acute exposure, the combined acute dietary exposure from food and water to triticonazole will occupy < 1% of the aPAD for (females 13 to 49 years old), the population subgroups receiving the greatest exposure.

2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to triticonazole from food and water will utilize 1.4% of the cPAD for all infants (< 1 year old), the subgroup receiving the greatest exposure. Based on the explanation in Unit III.C.3., regarding residential use patterns, chronic residential exposure to residues of triticonazole 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). Triticonazole is currently registered for use(s) 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 triticonazole.

Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded that the combined short-term food, water, and residential exposures aggregated result in aggregate MOEs of: 1,100 for children 1 to 2 years old, and 1,100 for all infants < 1 year old. Because the level of concern is for MOEs below 100, 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). Triticonazole is currently registered for use(s) that could result in intermediate-term residential exposure and the Agency has determined that it is appropriate to aggregate chronic exposure to triticonazole through food and water with intermediate-term exposures for triticonazole.

Using the exposure assumptions described in this unit for intermediate-term exposures, EPA has concluded that the combined intermediate-term food, water, and residential exposures aggregated result in aggregate MOEs of: 780 for children 1 to 2 years old, and 740 for all infants < 1 year old. Because the level of concern is for MOEs below 100, these MOEs are not of concern.

5. Aggregate cancer risk for U.S. population. Triticonazole is classified as “not likely to be carcinogenic to humans” based on the absence of significant tumor increases in two adequate rodent carcinogenicity studies. Thus, triticonazole is not expected to pose a cancer risk.

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 triticonazole residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Adequate enforcement methodology (liquid chromatography/mass spectrometry (LC/MS), and liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS) methods (Method 148.02) is available to enforce the tolerance expression. These methods may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: [phone]; e-mail address: [e-mail].

B. International Residue Limits

There are no established Codex or Mexican maximum residue levels (MRLs)/tolerances for triticonazole on wheat or barley. Triticonazole is registered as a seed treatment in Canada for oats, barley, and wheat, and has established MRL levels at 0.01 ppm on barley, oats, and wheat and for livestock commodities at 0.05 ppm. The Canadian MRLs on barley, oats, and wheat are in harmony with the United States' 0.01 ppm tolerance level for grain, cereal, group 15, except rice. Additionally, no U.S. tolerances have been established on livestock commodities. No harmonization issues exist in connection with the proposed use on turf.

C. Revisions to Petitioned-for Tolerances

EPA determined the tolerances for grain, cereal, group 15, except rice, should be established at 0.01 ppm, based on a harmonization concern with Canada, and residue data which supported this tolerance level. Thus the proposed tolerance level of 0.05 ppm was deemed excessive. Upon establishing the grain, cereal, group 15, except rice, tolerance at 0.01 ppm, the individual tolerances established for barley, straw; wheat, forage; wheat, grain; wheat, hay; and wheat, straw at 0.05 ppm are being removed from 40 CFR 180.583(a).

V. Conclusion

Therefore, tolerances are established for residues of triticonazole, (1RS)-(E)-5-[(4-chlorophenyl)methylene]-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol, in or on grain, cereal, group 15, except rice, at 0.01 ppm, and grain, cereal, forage, fodder and straw, group 16, except rice, at 0.10 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 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) (Public Law 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).
