The Codex has not established any MRLs for clomazone. asabaliauskas on DSK3SPTVN1PROD with RULES V. Conclusion Therefore, tolerances are established for residues of clomazone, 2-[(2chlorophenyl)methyl]-4,4-dimethyl-3isoxazolidinone, in or on asparagus at 0.05 ppm and soybean, vegetable, succulent at 0.05 ppm. VI. Statutory and Executive Order Reviews This action establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (59 FR 7629, February 16, 1994). Since tolerances and exemptions that are established on the basis of a petition under FFDCA section 408(d), such as the 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 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 VerDate Sep<11>2014 16:33 Nov 09, 2016 Jkt 241001 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).

Summary of Petitioned-For Tolerance In the Federal Register of November 25, 2015 (80 FR 73695) (FRL–9937–14), 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 5F8381) by Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Drive, Research Triangle Park, NC. The petition requested that 40 CFR 180.626 be amended by establishing tolerances for residues of the fungicide, prothioconazole in or on cotton, undelinted seed (crop subgroup 20C) at 0.4 parts per million (ppm) and to amend the existing tolerance in or on sugar beet, roots from 0.25 ppm to 0.3 ppm. That document referenced a summary of the petition prepared by Bayer CropScience, the registrant, which is available in the docket, http:// www.regulations.gov. A comment was received in response to the notice of filing. EPA’s response to this comment is discussed in Unit IV.C. Based upon review of the data supporting the petition, EPA has determined that the sugar beet root tolerance does not need to be increased to 0.30 ppm. The reason for this determination is explained in Unit IV.D. In the Federal Register of August 29, 2016 (81 FR 59165) (FRL–9950–22), 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 5F8381) by Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Drive, Research Triangle Park, NC. The petition requested that 40 CFR 180.626 be amended by establishing tolerances for residues of the fungicide, prothioconazole in or on cotton, gin byproducts at 4.0 ppm. That document referenced a summary of the petition prepared by Bayer CropScience, the registrant, which is available in the docket, http://www.regulations.gov. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 There were no comments received in response to the notice of filing. III. Aggregate Risk Assessment and Determination of Safety Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is ‘‘safe.’’ Section 408(b)(2)(A)(ii) of FFDCA defines ‘‘safe’’ to mean that ‘‘there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.’’ This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to ‘‘ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .’’ Consistent with FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure for prothioconazole including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with prothioconazole 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. Prothioconazole degrades into different compounds in different matrices, with prothioconazole-desthio (desthio) being the metabolite and degradate of concern. The target organs of prothioconazole and the desthio metabolite include the liver, kidney, bladder, thyroid and blood. In addition, the chronic studies showed body weight and food consumption changes, and toxicity to the lymphatic and gastrointestinal systems. E:\FR\FM\10NOR1.SGM 10NOR1 Federal Register / Vol. 81, No. 218 / Thursday, November 10, 2016 / Rules and Regulations Developmental studies show that prothioconazole and its metabolites produce adverse effects including malformations in the conceptus at levels equal to or below maternally toxic levels, particularly those studies conducted using prothioconazoledesthio. Reproduction studies in the rat with prothioconazole and prothioconazole-desthio suggest that these chemicals do not adversely affect reproductive parameters or the offspring except at parentally toxic dose levels. Acute and subchronic neurotoxicity studies, as well as a developmental neurotoxicity study, raise no neurotoxicity concerns. Immunotoxicity data show that prothioconazole is not an immunotoxicant. The available carcinogenicity and/or chronic studies in the mouse and rat, using both prothioconazole and prothioconazole-desthio, show no increase in tumor incidence and EPA has concluded that prothioconazole and its metabolites are not carcinogenic. Specific information on the studies received and the nature of the adverse effects caused by prothioconazole as well as the no-observed-adverse-effectlevel (NOAEL) and the lowest-observedadverse-effect-level (LOAEL) from the toxicity studies can be found at http:// www.regulations.gov in the document titled ‘‘Prothioconazole: Human Health Risk Assessment for a Proposed Tolerance on Cottonseed Subgroup 20C, a Tolerance Amendment on Sugar Beet Roots, and New Use Requests for Cotton, Sugar Beet, Soybean, and Dried Shelled Pea and Bean’’ on page 32 in docket ID number EPA–HQ–OPP–2015– 0722. 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 78919 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:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/assessinghuman-health-risk-pesticides. A summary of the toxicological endpoints for prothioconazole used for human risk assessment is shown in Table 1. of this unit.

In evaluating dietary exposure to prothioconazole, EPA considered exposure under the petitioned-for tolerances as well as all existing prothioconazole tolerances in VerDate Sep<11>2014 16:33 Nov 09, 2016 Jkt 241001 40 CFR 180.626. EPA assessed dietary exposures from prothioconazole 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 PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 occurring as a result of a 1-day or single exposure. Such effects were identified for prothioconazole for females 13–50 years old. In estimating acute dietary exposure, EPA used food consumption information from the United States Department of Agriculture’s National E:\FR\FM\10NOR1.SGM 10NOR1 asabaliauskas on DSK3SPTVN1PROD with RULES 78920 Federal Register / Vol. 81, No. 218 / Thursday, November 10, 2016 / Rules and Regulations Health and Nutrition Examination Survey, What We Eat in America, (NHANES/WWEIA; 2003–2008). As to residue levels in food, EPA assumed tolerance-level values for the proposed new uses and existing tolerances on berries and cucurbit vegetables, average field trial residues for all other commodities and empirical processing factors. With respect to sugar beet, the registrant-proposed tolerance value of 0.30 was incorporated in the dietary assessment, however, the Agency is leaving the tolerance at 0.25 ppm. The use of this higher residue level in the dietary assessment will serve as an overestimate of actual exposure to residues in/on sugar beet roots. 100 percent crop treated (PCT) was assumed for all proposed and established commodities. ii. Chronic exposure. In conducting the chronic dietary exposure assessment EPA used the food consumption data from the USDA 2003–2008 NHANES/ WWEIA. As to residue levels in food, EPA assumed tolerance-level values for the proposed new uses and existing tolerances on berries and cucurbit vegetables, average field trial residues for all other commodities and empirical processing factors. With respect to sugar beet, the registrant-proposed tolerance value of 0.30 was incorporated in the dietary assessment; however, the Agency is leaving the existing tolerance at 0.25 ppm. The use of this higher residue level in the dietary assessment will serve as an overestimate of actual exposure to residues in/on sugar beet roots. 100 PCT was assumed for all proposed and established commodities. iii. Cancer. Based on the data summarized in Unit III.A., EPA has concluded that prothioconazole does not pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk was not conducted. iv. Anticipated residue and PCT information. Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and information on the anticipated residue levels of pesticide residues in food and the actual levels of pesticide residues that have been measured in food. If EPA relies on such information, EPA must require pursuant to FFDCA section 408(f)(1) that data be provided 5 years after the tolerance is established, modified, or left in effect, demonstrating that the levels in food are not above the levels anticipated. For the present action, EPA will issue such data call-ins as are required by FFDCA section 408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be required to be submitted no later than VerDate Sep<11>2014 16:33 Nov 09, 2016 Jkt 241001 5 years from the date of issuance of these tolerances. 2. Dietary exposure from drinking water. The Agency used screening level water exposure models in the dietary exposure analysis and risk assessment for prothioconazole in drinking water. These simulation models take into account data on the physical, chemical, and fate/transport characteristics of prothioconazole. Further information regarding EPA drinking water models used in pesticide exposure assessment can be found at http://www2.epa.gov/ pesticide-science-and-assessingpesticide-risks/about-water-exposuremodels-used-pesticide. Based on the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM GW) models, the estimated drinking water concentrations (EDWCs) of prothioconazole for acute exposures are estimated to be 109 parts per billion (ppb) for surface water and 132 ppb for ground water and for chronic exposures are estimated to be 97 ppb for surface water and 128 ppb for ground 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 132 ppb was used to assess the contribution to drinking water. For chronic dietary risk assessment, the water concentration of value 128 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 nonoccupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Prothioconazole is not registered for any specific use patterns that would result in residential 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.’’ Prothioconazole 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 PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 toxicity. Evidence is needed to establish that the chemicals operate by the same, or essentially the same, sequence of major biochemical events in mammals (EPA, 2002). In the case of conazoles, however, a variable pattern of toxicological responses is found. Some are hepatotoxic and hepatocarcinogenic in mice. Some induce thyroid tumors in rats. 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 prothioconazole shares a common mechanism of toxicity with any other conazole pesticide, and EPA is not following a cumulative risk approach for this tolerance action. For information regarding EPA’s procedures for cumulating effects from substances found to have a common mechanism of toxicity, see EPA’s Web site at http:// www2.epa.gov/pesticide-science-andassessing-pesticide-risks/cumulativeassessment-risk-pesticides. Prothioconazole is a triazole-derived pesticide. This class of compounds can form the common metabolite 1,2,4triazole and two triazole conjugates (triazolylalanine and triazolylacetic acid). To support existing tolerances and to establish new tolerances for triazole-derivative pesticides, including prothioconazole, 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). The Agency retained a 3X for the LOAEL to NOAEL safety factor when the reproduction study was used. In addition, the Agency retained a 10X for the lack of studies including a developmental neurotoxicity (DNT) study. 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 E:\FR\FM\10NOR1.SGM 10NOR1 Federal Register / Vol. 81, No. 218 / Thursday, November 10, 2016 / Rules and Regulations asabaliauskas on DSK3SPTVN1PROD with RULES Identification (ID) Number EPA–HQ– OPP–2005–0497. An updated dietary exposure and risk analysis for the common triazole metabolites 1,2,4-triazole (T), triazolylalanine (TA), triazolylacetic acid (TAA), and triazolylpyruvic acid (TP) was completed on April 9, 2015, in association with registration requests for several triazole fungicides, propiconazole, difenoconazole, and flutriafol. That analysis concluded that risk estimates were below the Agency’s level of concern for all population groups. The proposed new uses of prothioconazole are not expected to significantly increase the dietary exposure estimates for free triazole or conjugated triazoles. This assessment may be found on http:// www.regulations.gov by searching for the following title and docket number: ‘‘Common Triazole Metabolites: Updated Aggregate Human Health Risk Assessment to Address The New Section 3 Registrations For Use of Propiconazole on Tea, Dill, Mustard Greens, Radish, and Watercress; Use of Difenoconazole on Globe Artichoke, Ginseng and Greenhouse Grown Cucumbers and Conversion of the Established Foliar Uses/Tolerances for Stone Fruit and Tree Nut Crop Groups to Fruit, Stone, Group 12–12 and the Nut, Tree, Group 14–12.; and Use of Flutriafol on Hops’’ (located in docket ID number EPA–HQ– OPP–2014–0788). 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. There are adequate data in the prothioconazole/prothioconazoledesthio toxicological database to characterize the potential for pre-natal or post-natal risks to infants and children: Two-generation reproduction studies in rats; developmental studies in rats and rabbits; and a DNT study in rats. The effects seen in these studies suggest that offspring are more VerDate Sep<11>2014 16:33 Nov 09, 2016 Jkt 241001 susceptible: Offspring adverse effects were seen at levels below the LOAELs for maternal toxicity and, in general, were of comparable or greater severity compared to the effects observed in adults. However, clear NOAELs are established for offspring and fetal effects. The most sensitive effects (malformed vertebral body and ribs, anthrogryposis, and other multiple malformations) seen in the fetuses of a rabbit developmental study are established as the toxicity endpoints with a POD of 2 mg/kg/day. This POD is protective all fetal and offspring effects seen in the developmental toxicity and developmental neurotoxicity studies. 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 prothioconazole is complete. ii. No neurotoxicity was seen in acute and subchronic neurotoxicity studies and other studies with prothioconazole or prothioconazole-desthio. Although offspring neurotoxicity was found, characterized by peripheral nerve lesions in the developmental neurotoxicity study on prothioconazoledesthio, the increase was seen only in the highest dose group at 105 mg/kg/ day. Further, a NOAEL was established for the peripheral nerve lesions and all of the PODs used in the risk assessment were protective of this finding. iii. Evidence of quantitative and qualitative susceptibility of offspring were observed in the developmental studies. However, basing the POD on the offspring in the most sensitive of these studies provides the needed protection of offspring. iv. There are no residual uncertainties identified in the exposure databases. The dietary food exposure assessments were performed based on 100 PCT and EPA-recommended tolerance values for all of the proposed uses and existing tolerances on berries and cucurbit vegetables, average field trial residue levels for the remaining uses, and empirical processing factors. EPA made conservative (protective) assumptions in the ground and surface water modeling used to assess exposure to prothioconazole in drinking water. These assessments will not underestimate the exposure and risks posed by prothioconazole. E. Aggregate Risks and Determination of Safety EPA determines whether acute and chronic dietary pesticide exposures are PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 78921 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. Using the exposure assumptions discussed in this unit for acute exposure, the acute dietary exposure from food and water to prothioconazole will occupy 40% of the aPAD for females 13–49 years old, the only population group of concern. 2. Chronic risk. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that chronic exposure to prothioconazole from food and water will utilize 77% of the cPAD for all infants less than 1 year old, the population group receiving the greatest exposure. There are no residential uses for prothioconazole. 3. Short- and Intermediate-term risk. Short- and intermediate-term aggregate exposure takes into account short- and intermediate-term residential exposure plus chronic exposure to food and water (considered to be a background exposure level). Both short- and intermediate-term adverse effects were identified; however, prothioconazole is not registered for any use patterns that would result in either short- or intermediate-term residential exposure. Short- and intermediate-term risk is assessed based on short- and intermediate-term residential exposure plus chronic dietary exposure. Because there is no short- or 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 short-term risk), no further assessment of short- or intermediate-term risk is necessary, and EPA relies on the chronic dietary risk assessment for evaluating short- and intermediate-term risk for prothioconazole. 4. Aggregate cancer risk for U.S. population. Based on the lack of evidence of carcinogenicity in two adequate rodent carcinogenicity studies, prothioconazole is not expected to pose a cancer risk to humans. 5. 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 E:\FR\FM\10NOR1.SGM 10NOR1 78922 Federal Register / Vol. 81, No. 218 / Thursday, November 10, 2016 / Rules and Regulations from aggregate exposure to prothioconazole residues, including aggregate exposure to residues of the common metabolites of prothioconazole and other related conazole fungicides. IV. Other Considerations A. Analytical Enforcement Methodology Adequate liquid chromatography with tandem mass spectrometry (LC/MS/MS) methods are available for enforcing prothioconazole tolerances in crop and livestock commodities. 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. asabaliauskas on DSK3SPTVN1PROD with RULES 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. There are no Codex MRLs established for prothioconazole in or on cotton. The Codex has established MRLs for prothioconazole in or on sugar beet roots at 0.3 ppm. This MRL is different than the tolerances established for prothioconazole in the United States. The U.S. is keeping the tolerance previously established in or on beet, sugar, roots at 0.25 ppm based on an evaluation of the residue data and in order to remain harmonized with Canada. The registrant, Bayer CropScience, has indicated their wish is to harmonize with Canada. Bayer cited data from the International Trade Macro Analysis Branch within the Economic Indicators Division of the U.S. Census Bureau, indicating that Canada and Mexico are the largest trade partners for U.S. exports of processed and refined sugar beets. Therefore, it would be more beneficial for U.S. growers if the U.S. VerDate Sep<11>2014 16:33 Nov 09, 2016 Jkt 241001 tolerance is harmonized with Canada instead of Codex. C. Response to Comments A comment was submitted by the Center for Food Safety and was primarily concerned about EPA’s consideration of the impacts of prothioconazole on the environment, pollinators, and endangered species. This comment is not relevant to the Agency’s evaluation of safety of the prothioconazole tolerances under section 408 of the FFDCA, which requires the Agency to evaluate the potential harms to human health, not effects on the environment. D. Revisions to Petitioned-For Tolerances Based on the review of the sugar beet residue data, EPA has determined that increasing the existing tolerance in or on beet, sugar, roots from 0.25 ppm to 0.30 ppm is not necessary, and therefore the sugar beet root tolerance will remain at 0.25 ppm. The registrant has indicated that they support this conclusion. V. Conclusion Therefore, tolerances are established for residues of prothioconazole in or on cotton gin byproducts at 4.0 ppm and the cottonseed subgroup 20C at 0.4 ppm. VI. Statutory and Executive Order Reviews This action establishes tolerances under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled ‘‘Regulatory Planning and Review’’ (58 FR 51735, October 4, 1993). Because this action has been exempted from review under Executive Order 12866, this action is not subject to Executive Order 13211, entitled ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997). This action does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any special considerations under Executive Order 12898, entitled ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 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 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).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of November 25, 2015 (80 FR 73695) (FRL-
9937-14), 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 
5F8381) by Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Drive, 
Research Triangle Park, NC. The petition requested that 40 CFR 180.626 
be amended by establishing tolerances for residues of the fungicide, 
prothioconazole in or on cotton, undelinted seed (crop subgroup 20C) at 
0.4 parts per million (ppm) and to amend the existing tolerance in or 
on sugar beet, roots from 0.25 ppm to 0.3 ppm. That document referenced 
a summary of the petition prepared by Bayer CropScience, the 
registrant, which is available in the docket, http://www.regulations.gov. A comment was received in response to the notice 
of filing. EPA's response to this comment is discussed in Unit IV.C.
    Based upon review of the data supporting the petition, EPA has 
determined that the sugar beet root tolerance does not need to be 
increased to 0.30 ppm. The reason for this determination is explained 
in Unit IV.D.
    In the Federal Register of August 29, 2016 (81 FR 59165) (FRL-9950-
22), 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 
5F8381) by Bayer CropScience, P.O. Box 12014, 2 T.W. Alexander Drive, 
Research Triangle Park, NC. The petition requested that 40 CFR 180.626 
be amended by establishing tolerances for residues of the fungicide, 
prothioconazole in or on cotton, gin byproducts at 4.0 ppm. That 
document referenced a summary of the petition prepared by Bayer 
CropScience, the registrant, which is available in the docket, http://www.regulations.gov. There were no comments received in response to the 
notice of filing.

III. Aggregate Risk Assessment and Determination of Safety

    Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a 
tolerance (the legal limit for a pesticide chemical residue in or on a 
food) only if EPA determines that the tolerance is ``safe.'' Section 
408(b)(2)(A)(ii) of FFDCA defines ``safe'' to mean that ``there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the pesticide chemical residue, including all anticipated dietary 
exposures and all other exposures for which there is reliable 
information.'' This includes exposure through drinking water and in 
residential settings, but does not include occupational exposure. 
Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue. . . 
.''
    Consistent with FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for prothioconazole including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with prothioconazole 
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.
    Prothioconazole degrades into different compounds in different 
matrices, with prothioconazole-desthio (desthio) being the metabolite 
and degradate of concern. The target organs of prothioconazole and the 
desthio metabolite include the liver, kidney, bladder, thyroid and 
blood. In addition, the chronic studies showed body weight and food 
consumption changes, and toxicity to the lymphatic and gastrointestinal 
systems.

[[Page 78919]]

    Developmental studies show that prothioconazole and its metabolites 
produce adverse effects including malformations in the conceptus at 
levels equal to or below maternally toxic levels, particularly those 
studies conducted using prothioconazole-desthio. Reproduction studies 
in the rat with prothioconazole and prothioconazole-desthio suggest 
that these chemicals do not adversely affect reproductive parameters or 
the offspring except at parentally toxic dose levels. Acute and 
subchronic neurotoxicity studies, as well as a developmental 
neurotoxicity study, raise no neurotoxicity concerns. Immunotoxicity 
data show that prothioconazole is not an immunotoxicant.
    The available carcinogenicity and/or chronic studies in the mouse 
and rat, using both prothioconazole and prothioconazole-desthio, show 
no increase in tumor incidence and EPA has concluded that 
prothioconazole and its metabolites are not carcinogenic.
    Specific information on the studies received and the nature of the 
adverse effects caused by prothioconazole 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 titled ``Prothioconazole: Human 
Health Risk Assessment for a Proposed Tolerance on Cottonseed Subgroup 
20C, a Tolerance Amendment on Sugar Beet Roots, and New Use Requests 
for Cotton, Sugar Beet, Soybean, and Dried Shelled Pea and Bean'' on 
page 32 in docket ID number EPA-HQ-OPP-2015-0722.

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

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to prothioconazole, EPA considered exposure under the 
petitioned-for tolerances as well as all existing prothioconazole 
tolerances in 40 CFR 180.626. EPA assessed dietary exposures from 
prothioconazole 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.
    Such effects were identified for prothioconazole for females 13-50 
years old. In estimating acute dietary exposure, EPA used food 
consumption information from the United States Department of 
Agriculture's National

[[Page 78920]]

Health and Nutrition Examination Survey, What We Eat in America, 
(NHANES/WWEIA; 2003-2008). As to residue levels in food, EPA assumed 
tolerance-level values for the proposed new uses and existing 
tolerances on berries and cucurbit vegetables, average field trial 
residues for all other commodities and empirical processing factors. 
With respect to sugar beet, the registrant-proposed tolerance value of 
0.30 was incorporated in the dietary assessment, however, the Agency is 
leaving the tolerance at 0.25 ppm. The use of this higher residue level 
in the dietary assessment will serve as an overestimate of actual 
exposure to residues in/on sugar beet roots. 100 percent crop treated 
(PCT) was assumed for all proposed and established commodities.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 2003-2008 
NHANES/WWEIA. As to residue levels in food, EPA assumed tolerance-level 
values for the proposed new uses and existing tolerances on berries and 
cucurbit vegetables, average field trial residues for all other 
commodities and empirical processing factors. With respect to sugar 
beet, the registrant-proposed tolerance value of 0.30 was incorporated 
in the dietary assessment; however, the Agency is leaving the existing 
tolerance at 0.25 ppm. The use of this higher residue level in the 
dietary assessment will serve as an overestimate of actual exposure to 
residues in/on sugar beet roots. 100 PCT was assumed for all proposed 
and established commodities.
    iii. Cancer. Based on the data summarized in Unit III.A., EPA has 
concluded that prothioconazole does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk was not conducted.
    iv. Anticipated residue and PCT information. Section 408(b)(2)(E) 
of FFDCA authorizes EPA to use available data and information on the 
anticipated residue levels of pesticide residues in food and the actual 
levels of pesticide residues that have been measured in food. If EPA 
relies on such information, EPA must require pursuant to FFDCA section 
408(f)(1) that data be provided 5 years after the tolerance is 
established, modified, or left in effect, demonstrating that the levels 
in food are not above the levels anticipated. For the present action, 
EPA will issue such data call-ins as are required by FFDCA section 
408(b)(2)(E) and authorized under FFDCA section 408(f)(1). Data will be 
required to be submitted no later than 5 years from the date of 
issuance of these tolerances.
    2. Dietary exposure from drinking water. The Agency used screening 
level water exposure models in the dietary exposure analysis and risk 
assessment for prothioconazole in drinking water. These simulation 
models take into account data on the physical, chemical, and fate/
transport characteristics of prothioconazole. Further information 
regarding EPA drinking water models used in pesticide exposure 
assessment can be found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    Based on the Pesticide Root Zone Model/Exposure Analysis Modeling 
System (PRZM/EXAMS) and Pesticide Root Zone Model Ground Water (PRZM 
GW) models, the estimated drinking water concentrations (EDWCs) of 
prothioconazole for acute exposures are estimated to be 109 parts per 
billion (ppb) for surface water and 132 ppb for ground water and for 
chronic exposures are estimated to be 97 ppb for surface water and 128 
ppb for ground 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 132 ppb was used to assess 
the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration of value 128 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). Prothioconazole is 
not registered for any specific use patterns that would result in 
residential 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.''
    Prothioconazole 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 mammals (EPA, 2002). In the case of 
conazoles, however, a variable pattern of toxicological responses is 
found. Some are hepatotoxic and hepatocarcinogenic in mice. Some induce 
thyroid tumors in rats. 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 prothioconazole shares a common mechanism of 
toxicity with any other conazole pesticide, and EPA is not following a 
cumulative risk approach for this tolerance action. For information 
regarding EPA's procedures for cumulating effects from substances found 
to have a common mechanism of toxicity, see EPA's Web site at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.
    Prothioconazole is a triazole-derived pesticide. This class of 
compounds 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 prothioconazole, 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). The Agency retained a 3X 
for the LOAEL to NOAEL safety factor when the reproduction study was 
used. In addition, the Agency retained a 10X for the lack of studies 
including a developmental neurotoxicity (DNT) study. 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

[[Page 78921]]

Identification (ID) Number EPA-HQ-OPP-2005-0497.
    An updated dietary exposure and risk analysis for the common 
triazole metabolites 1,2,4-triazole (T), triazolylalanine (TA), 
triazolylacetic acid (TAA), and triazolylpyruvic acid (TP) was 
completed on April 9, 2015, in association with registration requests 
for several triazole fungicides, propiconazole, difenoconazole, and 
flutriafol. That analysis concluded that risk estimates were below the 
Agency's level of concern for all population groups. The proposed new 
uses of prothioconazole are not expected to significantly increase the 
dietary exposure estimates for free triazole or conjugated triazoles.

and Use of Flutriafol on Hops'' (located in docket ID number EPA-HQ-
OPP-2014-0788).

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. There are adequate data in 
the prothioconazole/prothioconazole-desthio toxicological database to 
characterize the potential for pre-natal or post-natal risks to infants 
and children: Two-generation reproduction studies in rats; 
developmental studies in rats and rabbits; and a DNT study in rats. The 
effects seen in these studies suggest that offspring are more 
susceptible: Offspring adverse effects were seen at levels below the 
LOAELs for maternal toxicity and, in general, were of comparable or 
greater severity compared to the effects observed in adults. However, 
clear NOAELs are established for offspring and fetal effects. The most 
sensitive effects (malformed vertebral body and ribs, anthrogryposis, 
and other multiple malformations) seen in the fetuses of a rabbit 
developmental study are established as the toxicity endpoints with a 
POD of 2 mg/kg/day. This POD is protective all fetal and offspring 
effects seen in the developmental toxicity and developmental 
neurotoxicity studies.
    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 prothioconazole is complete.
    ii. No neurotoxicity was seen in acute and subchronic neurotoxicity 
studies and other studies with prothioconazole or prothioconazole-
desthio. Although offspring neurotoxicity was found, characterized by 
peripheral nerve lesions in the developmental neurotoxicity study on 
prothioconazole-desthio, the increase was seen only in the highest dose 
group at 105 mg/kg/day. Further, a NOAEL was established for the 
peripheral nerve lesions and all of the PODs used in the risk 
assessment were protective of this finding.
    iii. Evidence of quantitative and qualitative susceptibility of 
offspring were observed in the developmental studies. However, basing 
the POD on the offspring in the most sensitive of these studies 
provides the needed protection of offspring.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and EPA-recommended tolerance values for all of the proposed 
uses and existing tolerances on berries and cucurbit vegetables, 
average field trial residue levels for the remaining uses, and 
empirical processing factors. EPA made conservative (protective) 
assumptions in the ground and surface water modeling used to assess 
exposure to prothioconazole in drinking water. These assessments will 
not underestimate the exposure and risks posed by prothioconazole.

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. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to prothioconazole will occupy 40% of the aPAD for females 13-49 years 
old, the only population group of concern.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
prothioconazole from food and water will utilize 77% of the cPAD for 
all infants less than 1 year old, the population group receiving the 
greatest exposure. There are no residential uses for prothioconazole.
    3. Short- and Intermediate-term risk. Short- and intermediate-term 
aggregate exposure takes into account short- and intermediate-term 
residential exposure plus chronic exposure to food and water 
(considered to be a background exposure level).
    Both short- and intermediate-term adverse effects were identified; 
however, prothioconazole is not registered for any use patterns that 
would result in either short- or intermediate-term residential 
exposure. Short- and intermediate-term risk is assessed based on short- 
and intermediate-term residential exposure plus chronic dietary 
exposure. Because there is no short- or 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 short-term risk), no further assessment of 
short- or intermediate-term risk is necessary, and EPA relies on the 
chronic dietary risk assessment for evaluating short- and intermediate-
term risk for prothioconazole.
    4. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, prothioconazole is not expected to pose a cancer risk to 
humans.
    5. 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

[[Page 78922]]

from aggregate exposure to prothioconazole residues, including 
aggregate exposure to residues of the common metabolites of 
prothioconazole and other related conazole fungicides.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate liquid chromatography with tandem mass spectrometry (LC/
MS/MS) methods are available for enforcing prothioconazole tolerances 
in crop and livestock commodities.
    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 United Nations 
Food and Agriculture Organization/World Health Organization food 
standards program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    There are no Codex MRLs established for prothioconazole in or on 
cotton.
    The Codex has established MRLs for prothioconazole in or on sugar 
beet roots at 0.3 ppm. This MRL is different than the tolerances 
established for prothioconazole in the United States. The U.S. is 
keeping the tolerance previously established in or on beet, sugar, 
roots at 0.25 ppm based on an evaluation of the residue data and in 
order to remain harmonized with Canada. The registrant, Bayer 
CropScience, has indicated their wish is to harmonize with Canada. 
Bayer cited data from the International Trade Macro Analysis Branch 
within the Economic Indicators Division of the U.S. Census Bureau, 
indicating that Canada and Mexico are the largest trade partners for 
U.S. exports of processed and refined sugar beets. Therefore, it would 
be more beneficial for U.S. growers if the U.S. tolerance is harmonized 
with Canada instead of Codex.

C. Response to Comments

    A comment was submitted by the Center for Food Safety and was 
primarily concerned about EPA's consideration of the impacts of 
prothioconazole on the environment, pollinators, and endangered 
species. This comment is not relevant to the Agency's evaluation of 
safety of the prothioconazole tolerances under section 408 of the 
FFDCA, which requires the Agency to evaluate the potential harms to 
human health, not effects on the environment.

D. Revisions to Petitioned-For Tolerances

    Based on the review of the sugar beet residue data, EPA has 
determined that increasing the existing tolerance in or on beet, sugar, 
roots from 0.25 ppm to 0.30 ppm is not necessary, and therefore the 
sugar beet root tolerance will remain at 0.25 ppm. The registrant has 
indicated that they support this conclusion.

V. Conclusion

    Therefore, tolerances are established for residues of 
prothioconazole in or on cotton gin byproducts at 4.0 ppm and the 
cottonseed subgroup 20C at 0.4 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) in 
response to a petition submitted to the Agency. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this action has been 
exempted from review under Executive Order 12866, this action is not 
subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any 
information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA) (44 U.S.C. 3501 et seq.), nor does it require any 
special considerations under Executive Order 12898, entitled ``Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the 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 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).
