                    **Federal Register**
                     of August 5, 1998 (63 FR 41828) (FRL-5799-6) and August 24, 1999 (64 FR 46191) (FRL-6069-6), EPA issued notices pursuant to section 408 of FFDCA, 21 U.S.C. 346a as amended by FQPA (Public Law 104-170) announcing the filing of a pesticide petition (PP 8F4941) for tolerance by K-I Chemical U.S.A. Inc., Westchester Financial Center, 11 Martine Avenue, 9th Floor, White Plains, NY, 10606. These notices included a summary of the petition prepared by K-I Chemical U.S.A. Inc., the registrant. There were no comments received in response to the notices of filing. The petition requested that 40 CFR 180 be amended by establishing a tolerance for residues of the plant growth regulator, prohexadione calcium (cyclohexanecarboxylic acid, 3, 5-dioxo-4-(1-oxopropyl)-, ion(1-), calcium, calcium salt) in or on the raw agricultural commodities peanut nutmeat at 1.0, peanut hay at 0.6, pome fruit at 3.0, and cattle meat byproduct (kidney) at 0.1 parts per million (ppm). EPA is editorially correcting the tolerance expressions to read prohexadione calcium (calcium 3-oxido-5-oxo-4-propionylcyclohex-3-enecarboxylate) in or on the raw agricultural commodities peanuts at 1.0 ppm, peanut hay at 0.6 ppm, pome fruit crop group at 3.0 ppm, kidney of cattle, goats, hogs, horses, and sheep at 0.10 ppm and meat byproducts except kidney of cattle, goats, hogs, horses and sheep at 0.05 ppm. Section 408(b)(2)(A)(i) of the 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) 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) 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. . . .” EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7). III. Aggregate Risk Assessment and Determination of Safety Consistent with 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, consistent with section 408(b)(2), for a tolerance for residues of prohexadione calcium (calcium 3-oxido-5-oxo-4-propionylcyclohex-3-enecarboxylate) in or on the raw agricultural commodities peanuts at 1.0 ppm, peanut hay at 0.60 ppm, pome fruit group at 3.0 ppm, kidney of cattle, goats, hogs, horses, and sheep at 0.10 ppm and meat byproducts except kidney of cattle, goats, hogs, horses and sheep at 0.05 ppm. EPA's assessment of the dietary exposures and risks associated with establishing the tolerance 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. The nature of the toxic effects caused by prohexadione calcium are discussed in this unit. 1. A rat acute oral study with a lethal dose50
                     (LD50) greater than 5,000 milligrams (mg)/kilogram (kg) for males and females. None of the acute toxicity studies showed significant toxicity in the battery of tests (acute toxicity categories III and IV for all routes of exposure). 2. A 90-day rat feeding study with a No Observed Adverse Effect Level (NOAEL) of: 73.1 mg/kg/day for males and 80.4 mg/kg/day for females and a Lowest Observed Adverse Effect Level (LOAEL) of 734 mg/kg/day for males and 815 mg/kg/day for females based on squamous cell hyperplasia of the forestomach. 3. A 90-day mouse feeding study with a NOAEL of equal to or greater than 10,244 mg/kg/day for males and equal to or greater than 11,916 mg/kg/day for females, highest dose tested (HDT). 4. A 90-day dog dietary study with a NOAEL of 80 mg/kg/day and a LOAEL of 400 mg/kg/day based on moderate cortical areas of dilated basophilic tubules in the kidneys and decreased potassium levels. 5. A 1-year dog chronic feeding study with a NOAEL of 20 mg/kg/day and a LOAEL of 200 mg/kg/day based on histopathological changes in the kidneys and increased urinary volume and sodium concentrations. 6. A rat chronic feeding/carcinogenicity study with a NOAEL for systemic toxicity of 93.9 mg/kg/day and a LOAEL of 469 mg/kg/day based on decreased white blood cells (WBC) in males. There is no evidence of carcinogenicity under conditions of the study. 7. A mouse carcinogenicity study with a NOAEL for systemic toxicity of 279 mg/kg/day and a LOAEL of 2,847 mg/kg/day based on decreased body weight gain and food utilization and microscopic changes in the stomachs of males. There was no evidence of carcinogenicity under conditions of the study. 8. A 2-generation rat reproduction study with a parental systemic NOAEL of 35.5 mg/kg/day and parental systemic LOAEL of 385 mg/kg/day based on increased mortality and a reproductive NOAEL equal to or greater than 3,850 mg/kg/day (HDT) and an offspring NOAEL of 385 mg/kg/day and an offspring LOAEL of 3,850 mg/kg/day based on decreased pup body weight. 9. A rat developmental study with a maternal and developmental NOAEL 
                    ( print page 25657)
                    equal to or greater than 1,000 mg/kg/day (HDT). 10. A rabbit developmental study with a maternal NOAEL of 40 mg/kg/day and a maternal LOAEL of 200 mg/kg/day based on increased mortality, abortions, and decreased maternal body weight gain and a developmental NOAEL equal to or greater than 200 mg/kg/day (HDT). A second rabbit developmental study with a maternal and developmental NOAEL equal to or greater than 150 mg/kg/day (HDT). A third rabbit developmental study with a maternal NOAEL of 100 mg/kg/day and a maternal LOAEL of 350 mg/kg/day based on premature deliveries and a developmental NOAEL equal to or greater than 350 mg/kg/day (HDT). 11. A acute neurotoxicity screening battery with a NOAEL equal to or greater than 2,000 mg/kg (HDT). A subchronic neurotoxicity screening battery with a NOAEL equal to or greater than 1,148 mg/kg/day for males and 1,348 mg/kg/day for females (HDT). 12. Prohexadione calcium was negative for mutagenic/genotoxic effects in a Bacterial reverse mutation assay (Ames test), an 
                    *In vitro*
                     mammalian gene mutation assay, an 
                    *In vitro*
                     mammalian chromosome aberration (Chinese hampster ovary (CHO) cells) study, an 
                    *In vivo*
                     mammalian chromosome aberration (rat bone marrow cells) study, a Mammalian erythrocyte micronucleus test, an unscheduled DNA synthesis (UDS) in primary rat hepatocytes study, and a Rec assay with 
                    *Bacillus subtilis*
                     study. 13. Following oral treatment of rats, prohexadione calcium was rapidly absorbed with highest tissue/carcass concentrations obtained within 30 minutes; however, absorption became saturated at the highest dose. The test material did not accumulate in the tissues. For low dose animals, renal excretion was the primary route of elimination. At the high dose, fecal excretion became the primary route of elimination. The primary excreta metabolite was identified as the free acid. B. Toxicological Endpoints 1. 
                    *Acute toxicity*. EPA could not identify any toxicological effects that could be attributable to a single oral exposure (dose) in any of the available toxicological studies. 2. 
                    *Chronic toxicity*. EPA has established the Chronic Reference Dose (cRfD) for prohexadione calcium at 0.80 mg/kg/day. This cRfD is based on both the subchronic and chronic toxicity studies in dogs. Since a similar endpoint of equal severity (minimal and moderate dilation of basophilic tubules) was observed in both studies, the results of the two studies can be evaluated using a single dose-response curve. The NOAEL of 80 mg/kg/day from the subchronic study due to the wider dose spread than in the 1-year study and an uncertainty factor of 100 (10x for interspecies extrapolation, 10x for intraspecies variability) were used to establish the cRfD. The NOAEL of 80 mg/kg/day was based on histopathological changes (dilated basophilic tubules) in the kidneys and clinical chemical changes seen at the LOAEL of 200 mg/kg/day. No additional uncertainty factor is needed because there is no increase in the severity of the lesions over time in the chronic study as compared to the subchronic study. Since an FQPA safety factor of 1x is applicable for chronic dietary risk assessment, the chronic population adjusted dose (cPAD) is equivalent to the cRfD of 0.80 mg/kg/day. 3. 
                    *Carcinogenicity*. The Health Effects Division HIARC has classified prohexadione calcium as “not likely to be carcinogenic to humans” based on the lack of carcinogenicity in rats and mice. C. Exposures and Risks 1. 
                    *From food and feed uses*. No tolerances have been previously established (40 CFR part 180) for the residues of prohexadione calcium, in or on raw agricultural commodities. Risk assessments were conducted by EPA to assess dietary exposures from prohexadione calcium as follows: *Chronic exposure and risk*
                    . The cPAD for prohexadione calcium is 0.8 mg/kg/day. A chronic dietary exposure analysis for prohexadione calcium was performed using the Dietary Exposure Evaluation Model (DEEMTM). Tolerance level residues were used and 100% crop treated was assumed for all pome fruit and peanut commodities. The chronic analysis was conducted for the U.S. population and all population subgroups. The chronic exposure estimates (food only) for the U.S. population and all population subgroups were less than 5% of the cPAD. 2. 
                    *From drinking water*. The estimated environmental concentration (EEC) for ground water is 0.001 part per billion (ppb) (from screening concentration in ground water (SCI-GROW) modeling). The EECs for surface water (from generic expected environmental concentration (GENEEC) modeling) are 36 ppb for the acute (peak) concentration and 2.6 ppb for the 56-day value (with 3x adjustment factor). 3. 
                    *From non-dietary exposure*. There are no non-food uses of prohexadione calcium currently registered under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended. No non-dietary exposures are expected for the general population. 4. 
                    *Cumulative exposure to substances with a common mechanism of toxicity*. Section 408(b)(2)(D)(v) 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 does not have, at this time, available data to determine whether prohexadione calcium has a common mechanism of toxicity with other substances or how to include this pesticide in a cumulative risk assessment. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, prohexadione calcium does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that prohexadione calcium has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the final rule for Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997). D. Aggregate Risks and Determination of Safety for U.S. Population 1. 
                    *Acute risk*. EPA could not identify any toxicological effects that could be attributable to a single oral exposure (dose) in any of the available toxicological studies. 2. 
                    *Chronic risk*. Using the DEEM chronic exposure assumptions described in this unit, EPA has concluded that aggregate exposure from food will utilize less than 1% of the cPAD for the U.S. population. The major identifiable subgroup with the highest aggregate exposure is all infants (< 1 year old) which utilizes 2.3% of the cPAD. EPA generally has no concern for exposures below 100% of the cPAD because the cPAD represents the level at or below which daily aggregate dietary exposure over a lifetime will not pose appreciable risks to human health. The drinking water level of comparisons (DWLOCs) for chronic exposure to prohexadione calcium in drinking water calculated for the U.S. population was 28,000 ppb, for females, 13-50 years old, was 24,000 ppb and for all infants the DWLOC was 8,000 ppb. The EEC for 
                    ( print page 25658)
                    ground water is 0.001 ppb (from SCI-GROW modeling). The EEC for surface water (from GENEEC modeling) is 2.6 ppb for the 56-day value (with 3x adjustment factor). EPA's chronic DWLOC are well above the estimated exposures for prohexadione calcium in water for the subgroups of concern. Conservative model estimates (GENEEC and SCI-GROW) of the concentrations of prohexadione calcium in surface and ground water indicate that exposure will be minimal. 3. 
                    *Short- and intermediate-term risk*. Short- and intermediate-term aggregate risk assessments were not performed because there are no residential uses proposed for prohexadione calcium. 4. 
                    *Determination of safety*. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result from aggregate exposure to prohexadione calcium residues. E. Aggregate Risks and Determination of Safety for Infants and Children 1. 
                    *Safety factor for infants and children*. In assessing the potential for additional sensitivity of infants and children to residues of prohexadione calcium, EPA considered data from developmental toxicity studies in the rat and rabbit and a 2-generation reproduction study in the rat. The developmental toxicity studies are designed to evaluate adverse effects on the developing organism resulting from maternal pesticide exposure gestation. Reproduction studies provide information relating to effects from exposure to the pesticide on the reproductive capability of mating animals and data on systemic toxicity. FFDCA section 408 provides that EPA shall apply an additional tenfold 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 data base unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a margin of exposure (MOE) analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. EPA believes that reliable data support using the standard uncertainty factor (usually 100 for combined interspecies and intraspecies variability) and not the additional tenfold MOE/uncertainty factor when EPA has a complete data base under existing guidelines and when the severity of the effect in infants or children or the potency or unusual toxic properties of a compound do not raise concerns regarding the adequacy of the standard MOE/safety factor. The prenatal and postnatal toxicology data base for prohexadione calcium is adequate. The results of these studies indicated no quantitative or qualitative increase in susceptibility of rats or rabbits to 
                    *in utero*
                     and/or postnatal exposure to prohexadione. No developmental effects were seen at doses up to the limit dose (1,000 mg/kg/day) in the rat developmental toxicity study or up to the highest doses tested (150, 200, and 350 mg/kg/day) in three rabbit developmental toxicity studies. In the 2-generation reproduction study in rats, the effects in the offspring were observed only at treatment levels which resulted in evidence of parental toxicity. A developmental neurotoxicity (DNT) study is not required. No neuropathology or central nervous system (CNS) malformations were seen in the developmental toxicity studies. In the 2-generation reproduction study in rats, there were no findings in pups that were suggestive of changes in neurological development, although no functional assessment was performed. Additionally, there was no evidence of neurotoxicity in either the acute or subchronic neurotoxicity studies in rats and no evidence of neurotoxicity in other studies. The Agency concluded that an extra safety factor to protect infants and children is not needed based on the following considerations: i. The prenatal and postnatal toxicology data base is complete, there is no indication of increased susceptibility, and a developmental neurotoxicity study is not required. ii. The dietary (food and drinking water) exposure assessments will not underestimate the potential exposures for infants and children from the use of prohexadione calcium (currently there are no proposed residential uses and, therefore, non-occupational exposure is not expected). 2. 
                    *Determination of safety*. Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to prohexadione calcium residues. IV. Other Considerations A. Metabolism in Plants and Animals The nature of the residue in peanuts, pome fruit crop group, and livestock is adequately understood. The residues of concern for the tolerance expression are parent. Based on the results of animal metabolism studies, tolerances established for kidney and meat byproducts will cover any secondary residues that would occur in animal commodities from the use on peanuts and pome fruits. B. Analytical Enforcement Methodology Adequate enforcement methodology (gas chromatography and mass selective detector) is available to enforce the tolerance expression. The method may be requested from: Calvin Furlow, PRRIB, IRSD (7502C), Office of Pesticide Programs, Environmental Protection Agency, Ariel Rios Bldg., 1200 Pennsylvania Ave., NW., Washington, DC 20460; telephone number: (703) 305-5229; e-mail address: furlow.calvin@epa.gov. C. Magnitude of Residues The qualitative nature of the residue of prohexadione calcium in plants is adequately understood for the purpose of this petition. The metabolism of prohexadione calcium in apples and peanuts is similar. Prohexadione calcium is rapidly metabolized to prohexadione and parent-like oxidative intermediates and ultimately to tricarballylic acid (TCA), citric acid, and other natural products from the plant carbon pool. Only the parent compound needs to be included in the tolerance expression for pome fruit and peanuts and is the only compound to be included in the dietary risk assessments. D. International Residue Limits There are no Codex Alimentarius Commission (Codex), Canadian, or Mexican Maximum Residue Levels (MRLs) for prohexadione calcium. E. Rotational Crop Restrictions No tolerances for inadvertent residues of prohexadione calcium are required in rotational crops at this time. V. Conclusion Therefore, the tolerances are established for residues of prohexadione calcium (calcium 3-oxido-5-oxo-4-propionylcyclohex-3-enecarboxylate) in or on the raw agricultural commodities peanuts at 1.0 ppm, peanut hay at 0.60 ppm, pome fruit crop group at 3.0 ppm, kidney of cattle, goats, hogs, horses, and sheep at 0.10 ppm, and meat byproducts except kidney of cattle, goats, hogs, horses and sheep at 0.05 ppm. VI. Objections and Hearing Requests Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. 
                    ( print page 25659)
                    Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA of 1996, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d), as was provided in the old FFDCA sections 408 and 409. However, the period for filing objections is now 60 days, rather than 30 days. A. What Do I Need to Do to File an Objection or Request a Hearing?

You may also submit an electronic copy of your request at many Federal Depository Libraries. B. When Will the Agency Grant a Request for a Hearing? A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32). VII. Regulatory Assessment Requirements This final rule establishes a tolerance under FFDCA section 408(d) in response to a petition submitted to the Agency. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled 
                    *Regulatory Planning and Review*
                     (58 FR 51735, October 4, 1993). 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.*, or 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). Nor does it require any prior consultation as specified by Executive Order 13084, entitled 
                    *Consultation and Coordination with Indian Tribal Governments*
                     (63 FR 27655, May 19, 1998); special considerations as required by Executive Order 12898, entitled 
                    *Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations*
                     (59 FR 7629, February 16, 1994); or require OMB review or any Agency action under Executive Order 13045, entitled 
                    *Protection of Children from Environmental Health Risks and Safety Risks*
                     (62 FR 19885, April 23, 1997). 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). 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. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and 
                    ( print page 25660)
                    responsibilities among the various levels of government, as specified in Executive Order 13132, entitled 
                    *Federalism*
                     (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This final rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of FFDCA section 408(n)(4). VIII. Submission to Congress and the Comptroller General The Congressional Review Act, 5 U.S.C. 801 
                    *et seq.*, as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, 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 Environmental protection
