                    **Federal Register**
                     of April 23, 2003 (68 FR 19991) (FRL-7303-1), 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 3F6556) by Bayer CropScience, 2 T.W. Alexander Drive, Research Triangle Park, North Carolina  27709. The petition requests that 40 CFR 180.609 be amended by establishing tolerances for the combined residues of the fungicide fluoxastrobin, (1E)-[2-[[6-(2-chlorophenoxy)-5-fluoro-4-pyrimydinyl]-oxy]phenyl](5,6-dihydro-1,4,2-dioxazin-3-yl)methanone O-methyloxime, in or on the raw agricultural commodities (RACs) alfalfa, forage at 0.05 parts per million (ppm); alfalfa, hay at 1.0 ppm; cotton, gin byproducts at 0.02 ppm; grain, cereal, forage at 0.10 ppm; grain, cereal, hay at 0.10 ppm; grain, cereal, stover at 0.10 ppm; grain, cereal, straw at 0.10 ppm; grass, forage at 0.10 ppm; grass, hay at 0.50 ppm; legume, forage at 0.05 ppm; legume, hay at 0.05 ppm; legume, seed at 0.01 ppm; peanut at 0.01 ppm; peanut, hay at 20 ppm; peanut, refined oil at 0.10 ppm; tomato, paste at 2.0 ppm; vegetable, foliage of legume, group 7 at 0.05 ppm; vegetable, fruiting, group at 1.0 ppm; vegetable, leafy, petioles, except brassica, subgroup at 5.0 ppm; and vegetable, tuberous and corm, subgroup at 0.01 ppm.  The petition also requests that 40 CFR 180.609 be amended by establishing tolerances for 
                    ( print page 54641)
                    the combined residues of  fluoxastrobin, (1E)-[2-[[6-(2-chlorophenoxy)-5-fluoro-4-pyrimydinyl]-oxy]phenyl](5,6-dihydro-1,4,2-dioxazin-3-yl)methanone O-methyloxime, and its phenoxy-hydroxypyrimidine metabolite, 6-(2-chlorophenoxy)-5-fluoro-4-pyrimidinol, in or on the RACs cattle, fat at 0.10 ppm; cattle, meat at 0.05 ppm; cattle, meat byproducts at 0.20 ppm; milk at 0.01 ppm; and milk, fat at 0.10 ppm.  That notice included a summary of the petition prepared by Bayer CropScience, the registrant.  Several comments concerning the notice were received.  They are described and discussed in Unit V. Based on EPA's review, the aforementioned petition was revised by the petitioner by adjusting some tolerance levels, revising the tolerance expression, and revising the commodity nomenclature to reflect the correct commodity definitions.  The tolerance expression was revised to reflect the fact that fluoxastrobin E-isomer, and not the mixture of E- and Z-isomers, is the proposed active ingredient.  The petition was also revised, based on extensive field rotational crop data, to add indirect tolerances for the combined residues of fluoxastrobin and its Z-isomer in/on rotated crops.  As revised, the petition seeks the establishment of  tolerances for combined residues of fluoxastrobin, (1E)-[2-[[6-(2-chlorophenoxy)-5-fluoro-4- pyrimydinyl]oxy]phenyl](5,6-dihydro-1,4,2-dioxazin-3-yl)methanone O-methyloxime, and its Z isomer, (1Z)-[2-[[6-(2-chlorophenoxy)-5-fluoro-4-pyrimydinyl]oxy]phenyl](5,6-dihydro-1,4,2-dioxazin-3-yl)methanone O-methyloxime, in or on the RACs leaf petioles subgroup 4B at 4.0 ppm; peanut at 0.010 ppm; peanut, hay at 20.0 ppm; peanut, refined oil at 0.030 ppm; tomato, paste at 1.5 ppm; vegetable, fruiting, group 8 at 1.0 ppm; and vegetable, tuberous and corm, subgroup 1C at 0.010 ppm, the establishment of tolerances for indirect or inadvertent residues for the combined residues of fluoxastrobin and its Z isomer, in or on the RACs alfalfa, forage at 0.050 ppm; alfalfa, hay at 0.10 ppm; cotton, gin byproducts at 0.020 ppm; grain, cereal, forage, fodder, and straw, group 16 at 0.10 ppm; grass, forage at 0.10 ppm; grass, hay at 0.50 ppm; and vegetable, foliage of legume, group 7 at 0.050 ppm; and the establishment of tolerances for the combined residues of fluoxastrobin, its Z isomer, and its phenoxy-hydroxypyrimidine metabolite, 6-(2-chlorophenoxy)-5-fluoro-4-pyrimidinol, expressed as fluoxastrobin, in or on the RACs cattle, fat at 0.10 ppm; cattle, meat at 0.05 ppm; cattle, meat byproducts at 0.10 ppm; goat, fat at 0.10 ppm; goat, meat at 0.05 ppm; goat, meat byproducts at 0.10 ppm; horse, fat at 0.10 ppm; horse, meat at 0.05 ppm; horse, meat byproducts 0.10 ppm; milk at 0.02 ppm; milk, fat at 0.50 ppm; sheep, fat at 0.10 ppm; sheep, meat at 0.05 ppm; and sheep, meat byproducts at 0.10 ppm. Section 408(b)(2)(A)(i) of FFDCA allows EPA to establish a tolerance (the legal upper 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....” 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 of FFDCA 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) 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, consistent with section 408(b)(2) of FFDCA, for the fluoxastrobin tolerances described in Unit II. EPA's assessment of exposures and risks associated with establishing these 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. The nature of the toxic effects caused by fluoxastrobin are discussed in Table 1. of this unit as well as the no observed adverse effect level (NOAEL) and the lowest observed adverse effect level (LOAEL) from the toxicity studies reviewed. **Table 1.—Subchronic, Chronic, and Other Toxicity**

Metabolism and pharmacokinetics-rat
Absorption, distribution, and metabolism were fully characterized in several rat metabolism studies using each of the three14
                            C-radiolabeled rings in fluoxastrobin.  Absorption was almost complete following a single oral low dose.  Peak plasma concentrations were attained within 0.5 to 8 hours depending on the dose and label position.  Fecal excretion was the major route of elimination while renal excretion was a secondary route and  elimination via expired air was negligible.  Fluoxastrobin was extensively metabolized as evidenced by the extensive metabolite profiles from urine, feces, and bile and the relative absence of parent compound (except in the feces of rats given the high dose).870.7600
Dermal penetration--monkey
Following an 8-hour dermal application in a male monkey, absorption was negligible (1.16% preliminary, 2.16% main).  The normalized absorption value for the main study was 2.31%.870.7800
Immunotoxicity-mouse (subacute feeding study)
No clinical signs of toxicity or mortality were found and no treatment-related effects were found on body weight, food intake, or B-cell activated, T-cell mediated IgM response to SRBC. Based on these findings, and findings in the 90-day oral rat study (no difference between the control and treated animals in spleen cell count, macrophage activities after PMA stimulation and plaque-forming cell assay after challenge with sheep erythrocytes), it was concluded that fluoxastrobin is not immunotoxic. However, the study is considered unacceptable because of uncertainty in dietary test material intake, failure to report spleen weight of each mouse at necropsy, and failure of the laboratory to demonstrate its capability in performing this type of assay.
 B. Toxicological Endpoints The highest dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect 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. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intraspecies differences. Three other types of safety or uncertainty factors may be used: “Traditional uncertainty factors;” the “special FQPA safety factor;” and the “default FQPA safety factor.”  By the term “traditional uncertainty factor,” EPA is referring to those additional uncertainty factors used prior to FQPA passage to account for database deficiencies.  These traditional uncertainty factors have been incorporated by the FQPA into the additional safety factor for the protection of infants and children.  The term “special FQPA safety factor” refers to those safety factors that are deemed necessary for the protection of infants and children primarily as a result of the FQPA.  The “default FQPA safety factor” is the additional 10X safety factor that is mandated by the statute unless it is decided that there are reliable data to choose a different additional factor 
                    ( print page 54644)
                    (potentially a traditional uncertainty factor or a special FQPA safety factor). For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by an UF of 100 to account for interspecies and intraspecies differences and any traditional uncertainty factors deemed appropriate (RfD = NOAEL/UF). Where a special FQPA safety factor or the default FQPA safety factor is used, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of safety factor. For non-dietary risk assessments (other than cancer) the UF is used to determine the LOC. For example, when 100 is the appropriate UF (10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC. The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk. A Q* is calculated and used to estimate risk which represents a probability of occurrence of additional cancer cases (e.g., risk). An example of how such a probability risk is expressed would be to describe the risk as one in one hundred thousand (1 X 10-5
                    ), one in a million (1 X 10-6
                    ), or one in ten million (1 X 10-7
                    ).  Under certain specific circumstances, MOE calculations will be used for the carcinogenic risk assessment. In this non-linear approach, a “point of departure” is identified below which carcinogenic effects are not expected. The point of departure is typically a  NOAEL based on an endpoint related to cancer effects though it may be a different value derived from the dose response curve. To estimate risk, a ratio of the point of departure to exposure (MOEcancer
                     = point of departure/exposures) is calculated. A summary of the toxicological endpoints for fluoxastrobin used for human risk assessment is shown in Table 2. of this unit: **Table 2.—Summary of Toxicological Dose and Endpoints for Fluoxastrobin for Use in Human Risk Assessment**

Classification: Not likely to be carcinogenic to humans.
 C. Exposure Assessment 1. 
                    *Dietary exposure from food and feed uses*.  As is described in Unit II., tolerances for fluoxastrobin are being established on a variety of raw agricultural commodities.  Risk assessments were conducted by EPA to assess dietary exposures from fluoxastrobin in food as follows: i. 
                    *Acute exposure*. Acute dietary 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 one-day or single exposure. The toxicological database for fluoxastrobin identified no adverse effect attributable to a single dose, therefore an acute dietary exposure assessment was not performed. ii. 
                    *Chronic exposure*
                    . In conducting the chronic dietary risk assessment EPA used the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database (DEEM-FCIDTM
                     version 2.0) and the LifelineTM
                     model, version 2.0, both of which incorporate food consumption data as reported by respondents in the USDA 1994-1996 and 1998 Nationwide Continuing Surveys of Food Intake by Individuals (CSFII).  The assumptions made for the chronic dietary exposure assessments were that residues, for all commodities, were present at 100% of the tolerance levels and fluoxastrobin was applied to 100% of each crop to which it may be applied. 
 
 2. 
                    *Dietary exposure from drinking water*. The Agency does not have drinking water monitoring exposure data to use in a comprehensive dietary exposure analysis and risk assessment for fluoxastrobin, a new pesticidal chemical. Because of this the Agency made drinking water concentration estimates by use of simulation or modeling, which takes into account data on the physical and chemical characteristics of fluoxastrobin. The Agency used the Pesticide Root Zone Model/Exposure Analysis Modeling System (PRZM/EXAMS (PRZM version 3.12 beta and EXAMS version 2.98.04)), to produce estimates of pesticide concentrations in an index reservoir (the surface water concentration estimates).  The Screening Concentrations in Ground Water (SCI-GROW) model was used to predict pesticide concentrations in shallow ground water (the ground water concentration estimates).  The surface water concentration analysis was based on the turf use, which has the highest labeled annual application rate and assumes the highest default value of 87% percentage cropped area (PCA) land use around the index reservoir.  The assumptions in this analysis are therefore also conservative.  The ground water concentration analysis was based on the maximum pesticide use rate (the turf use again), the persistence of fluoxastrobin in soil, and the ability of fluoxastrobin to leach. None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The primary use of these models by the Agency at this stage is to provide a screen for sorting out pesticides for which it is unlikely that drinking water concentrations would exceed human health levels of concern. Estimated drinking water concentrations (EDWCs) derived from these models are used to calculate drinking water levels of comparison (DWLOCs).  The DWLOCs are used as points of comparison against the EDWCs.  DWLOCs are theoretical upper limits on the concentration of a pesticide that could occur in drinking water without exceeding the size of the risk cup, considering the aggregate exposure to that pesticide in food and from residential uses. Since DWLOCs represent maximum allowable exposure to fluoxastrobin in drinking water, they are further discussed in the aggregate risk sections in Unit III.E. Based on the PRZM/EXAMS and SCI-GROW models, the EDWCs of fluoxastrobin for acute exposures are 28 parts per billion (ppb) for surface water and less than 1 ppb for ground water. The EDWCs for chronic exposures are 14 ppb for surface water and less than 1 ppb for ground 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). There is potential for homeowner exposure to fluoxastrobin in residential settings by entry to turf areas where this fungicide has previously been applied, such as lawns where children might play or golf courses that adults might be active on.  Therefore, risk assessments have been performed for residential postapplication scenarios.  However, only professional pest control operators will be allowed to make the turf applications so residential handler exposure was not evaluated. Since chemical-specific data were unavailable, the Agency used general current approaches for non-occupational assessment and believes that the calculated risks represent screening level estimates.  Maximum application rates have been used for all scenarios, and the risk estimates assume no dissipation of residues after day zero and do not consider removal of residues as a result of periodic cutting of the grass.  Additionally, the intermediate-term endpoint was used for dermal risk estimates, even though the non-occupational exposure duration is believed to mostly be short-term (as a result of the use pattern), because no short-term dermal toxicity endpoint was identified. 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.” Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to fluoxastrobin and any other substances and fluoxastrobin 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 fluoxastrobin 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 policy statements released by EPA's OPP concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's web site at 
                    *http://www.epa.gov/​pesticides/​cumulative/​*. D. Safety Factor for Infants and Children 1. 
                    *In general*. Section 408 of  FFDCA 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 on toxicity and exposure unless EPA determines based on reliable data 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 MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans. In applying this provision, EPA either retains the default value of 10X when reliable data do not support the choice of a different factor, or, if reliable data are available, EPA uses a different additional safety factor value based on the use of traditional uncertainty factors and/or special FQPA safety factors, as appropriate. 2. 
                    *Prenatal and postnatal sensitivity*. The toxicity database for fluoxastrobin, including acceptable developmental toxicity studies in rats and rabbits, as well as a two-generation reproduction toxicity study, provides no indication of prenatal and/or post-natal sensitivity. 3. 
                    *Conclusion*.  There is a complete toxicity data base for fluoxastrobin and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. The Agency therefore has recommended reducing the special FQPA SF to 1X, based on the following additional considerations.  First, there are no low risk concerns indicated by the various hazard studies.  The study data are of high quality, and there are no residual uncertainties with regard to the pre- and/or postnatal toxicity of this chemical.  Second, the dietary food exposure assessment utilizes proposed tolerance level or higher residues and 100% crop treated information for all commodities.  By using these screening-level assessments, chronic exposures and risks will not be underestimated. 
                    ( print page 54647)
                     Third, the dietary drinking water assessments utilize values generated by models and associated modeling parameters which are designed to provide conservative, health protective, high-end estimates of water concentrations.  Fourth, the residential exposure assessment utilizes activity-specific transfer coefficients and turf transferable residues (TTR), as well as maximum application rates for the postapplication scenario.  The residential assessment is based on reliable data and is unlikely to underestimate exposure/risk. E. Aggregate Risks and Determination of Safety To estimate total aggregate exposure to a pesticide from food, drinking water, and residential uses, the Agency calculates DWLOCs which are used as a point of comparison against  EDWCs.  DWLOC values are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses, not regulatory standards for drinking water . In calculating a DWLOC, the Agency determines how much of the acceptable exposure (i.e., the PAD) is available for exposure through drinking water [e.g., allowable chronic water exposure (mg/kg/day) = cPAD - (average food +  residential exposure)].  This allowable exposure through drinking water is the source of the DWLOC. A DWLOC will vary depending on the toxic endpoint, drinking water consumption, and body weights. Default body weights and consumption values as used by the EPA's Office of Water are used to calculate DWLOCs: 2 liter (L)/70 kg (adult male), 2L/60 kg (adult female), and 1L/10 kg (child). Default body weights and drinking water consumption values vary on an individual basis. This variation will be taken into account in more refined screening-level and quantitative drinking water exposure assessments.  Different populations will have different DWLOCs.  Generally, a DWLOC is calculated for each type of risk assessment used: Acute, short-term, intermediate-term, chronic, and cancer. When EDWCs for surface water and ground water are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to the pesticide in drinking water (when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. Because OPP considers the aggregate risk resulting from multiple exposure pathways associated with a pesticide's uses, levels of comparison in drinking water may vary as those uses change. If new uses are added in the future, OPP will reassess the potential impacts of residues of the pesticide in drinking water as a part of the aggregate risk assessment process. 1. 
                    *Acute risk*. The toxicological database for fluoxastrobin identified no adverse effect attributable to a single dose, therefore fluoxastrobin is not expected to pose an acute dietary risk. 2. 
                    *Chronic risk*. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to fluoxastrobin from food will utilize 10% of the cPAD for the U.S. population, 6% of the cPAD for all infants less than 1 year old, and 25% of the cPAD for children 1 to 2 years old, the children subpopulation with the greatest exposure.  Based on the use pattern, chronic residential exposure to residues of fluoxastrobin is not expected.  However, there is the potential for chronic dietary exposure to fluoxastrobin in drinking water.  After calculating DWLOCs and comparing them to the EDWCs for surface and ground water, EPA does not expect the aggregate exposure to exceed 100% of the cPAD, as shown in Table 3. of this unit: **Table 3.—Aggregate Risk Assessment for Chronic (Non-Cancer) Exposure to Fluoxastrobin**

 3. 
                    *Short- and intermediate-term risk*.  Short- and intermediate-term aggregate exposures both take into account residential exposure plus chronic exposure to food and water (considered to be a background exposure level).  Because all short- and intermediate-term quantitative hazard estimates (via the dermal and incidental oral routes) for fluoxastrobin are based on the same endpoint, a screening level, conservative aggregate risk assessment was conducted that combined the short-term incidental oral and intermediate-term dermal exposure estimates (i.e., the highest exposure estimates). Using the exposure assumptions described in this unit for intermediate-term exposures, EPA has concluded that food and residential exposures aggregated result in aggregate MOEs of 1,000 for the U.S. population, 1,100 for females 13-49 years old, and 180 for children 1-2 years old. These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses.  In addition, short- and intermediate-term DWLOCs were calculated and compared to the EDWCs for chronic exposure to fluoxastrobin in ground and surface water.  After calculating DWLOCs and comparing them to the EDWCs for surface and ground water, EPA does not expect short- and intermediate-term aggregate exposure to exceed the Agency's level of concern, as shown in Table 4. of this unit:

                    *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, and to infants and children from aggregate exposure to fluoxastrobin residues.

Comments In response to the notice of filing one communication was received from Susie Wilcher in the role of private citizen and one communication, undersigned by Ellen Connett, was received from the Fluoride Action Network (FAN).  The communications objected to establishment of the proposed tolerances for several reasons, some of them specific and others involving generalized and unsubstantiated disagreement with EPA's risk assessment methodologies or safety findings. Ms. Wilcher's comments contained general objections to the use of pesticides on food and to the use of animal testing to determine the safety of pesticides.  The Agency understands the commentor's concerns and recognizes that some individuals believe that pesticides should be banned completely.  However, under the existing legal framework provided by section 408 of the FFDCA EPA is authorized to establish pesticide tolerances or exemptions where persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. The Agency disagrees with the commenter's objections to animal testing. Since humans and animals have complex organ systems and mechanisms for the distribution of chemicals in the body, as well as processes for eliminating toxic substances from their systems, EPA relies on laboratory animals such as rats and mice to mimic the complexity of human and higher-order animal physiological responses when exposed to a pesticide. EPA is committed, however, to reducing the use of animals whenever possible. EPA-required studies include animals only when the requirements of sound toxicological science make the use of an animal absolutely necessary.  The Agency's goal is to be able to predict the potential of pesticides to cause harmful effects to humans and wildlife by using fewer laboratory animals as models and have been accepting data from alternative (to animals) test methods for several years.  As progress is made on finding or developing non-animal test models that reliably predict the potential for harm to humans or the environment, EPA expects that it will need fewer animal studies to make safety determinations. FAN submitted a number of different comments.  First, FAN asked whether fluoxastrobin was already registered in the United States and what are the names of the fluoxastrobin products used on residential turf and golf courses.  Fluoxastrobin is not currently registered but with the completion of this tolerance regulation that registration should be granted shortly.  To the best of EPA's knowledge, the product name under which fluoxastrobin is marketed for turf and golf course use is HEC 480 SC Fungicide. Second, FAN suggested that a 14-week feeding study using dogs showed an effect on the thyroid, which seems to conflict with the statement that “...There is no evidence to suggest that fluoxastrobin has any primary 
                    ( print page 54649)
                    endocrine disruptive potential.”  FAN stated that a “discussion or rationale” addressing this should have been provided.  EPA does believe that the thyroid effects seen in the dog study indicated that fluoxastrobin is an endocrine disruptor.  An effect on the thyroid gland, even though this gland is part of the endocrine system, does not necessarily mean that endocrine disruption has or will occur.  In this case, the effects observed in the thyroid gland were induced by effects fluoxastrobin had on liver enzymes and are therefore considered secondary. Third, FAN claimed that a “fuller discussion and description of the metabolites of fluoxastrobin should have been presented.”  The notice states: “The residue of concern is parent fluoxastrobin (sum of E and Z isomers).”  According to the Compendium of Pesticide Common Names, Fluoxastrobin “was provisionally approved for the (EZ)-isomer [193740-76-0] in April 2002.  The definition was changed to the (E)-isomer in January 2003 at the request of the sponsor...Because of this change it is not clear from the information supplied in this notice what isomer/metabolite are of concern.” Fluoxastrobin is the accepted common name for the pesticidally active E-isomer of (2-[6-(2-chlorophenoxy)-5-fluoro-4-pyrimidinyl]oxy phenyl)-5,6-dihydro-1,4,2-dioxazin-3-yl)methanone O-methyloxime.  The Z-isomer of fluoxastrobin is typically present at much lower levels (E:Z ratio of approximately 90:10).  Additionally, the Z-isomer of fluoxastrobin is considered to be a metabolite (photo-degradate) of fluoxastrobin.  The CAS Number Bayer CropScience initially obtained for fluoxastrobin pertained to both isomers combined.  After consultation with the Agency, the petitioner requested that fluoxastrobin (the pesticidally active E-isomer only) be designated as the active ingredient. The tolerances that are being established today include both fluoxastrobin (i.e. the E-isomer) and the Z-isomer and the risk assessment for these tolerances was based on exposures resulting from both isomers. Fourth, FAN requested that the Agency begin to incorporate the Chemical Abstract Service (CAS) numbers for “every chemical, and its metabolite(s)” in “all future reports, especially those published in the 
                    **Federal Register**
                    .”  EPA is evaluating the feasibility of such a step.  EPA would note, however, that not every molecule or substance has a CAS number.  Many metabolites do not have a CAS number, for example, because no application for a CAS number was made or is required.  CAS is also often not willing to assign CAS numbers to substances it believes are not able to be characterized well enough (some petroleum distillates, for example).  In addition, CAS numbers may be inappropriate in some types of reports.  However, the CAS number could be a useful identifier in certain documents for molecules which have one. FAN also commented that the data references cited in the notice of filing were not available in the docket, and that without this information, it was not possible to comment on the findings presented.  In response, the Agency transmitted to FAN the human health risk assessment and the toxicological studies used in that risk assessment. VI. Conclusion Therefore, tolerances requested for fluoxastrobin in the revised petition are established. VII. Objections and Hearing Requests Under section 408(g) of  FFDCA, as amended by 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.  Although the procedures in those regulations require some modification to reflect the amendments made to FFDCA by FQPA, EPA will continue to use those procedures, with appropriate adjustments, until the necessary modifications can be made.  The new section 408(g) of FFDCA 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) of  FFDCA, as was provided in the old sections 408 and 409 of  FFDCA. 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 must file your objection or request a hearing on this regulation in accordance with the instructions provided in this unit and in 40 CFR part 178.  To ensure proper receipt by EPA, you must identify docket ID number OPP-2003-0129 in the subject line on the first page of your submission.  All requests must be in writing, and must be mailed or delivered to the Hearing Clerk on or before November 15, 2005. 1. 
                    *Filing the request*.  Your objection must specify the specific provisions in the regulation that you object to, and the grounds for the objections (40 CFR 178.25).  If a hearing is requested, the objections must include a statement of the factual issues(s) on which a hearing is requested, the requestor's contentions on such issues, and a summary of any evidence relied upon by the objector (40 CFR 178.27).  Information submitted in connection with an objection or hearing request may be claimed confidential by marking any part or all of that information as CBI.  Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.  A copy of the information that does not contain CBI must be submitted for inclusion in the public record. Information not marked confidential may be disclosed publicly by EPA without prior notice. Mail your written request to: Office of the Hearing Clerk (1900L), Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001.  You may also deliver your request to the Office of the Hearing Clerk in Suite 350, 1099 14th
                     St., NW., Washington, DC 20005. The Office of the Hearing Clerk is open from 8 a.m. to 4 p.m., Monday through Friday, excluding legal holidays.  The telephone number for the Office of the Hearing Clerk is (202) 564-6255. 2. 
                    *Copies for the Docket*.  In addition to filing an objection or hearing request with the Hearing Clerk as described in Unit VII.A., you should also send a copy of your request to the PIRIB for its inclusion in the official record that is described in 
                    **ADDRESSES**
                    .  Mail your copies, identified by docket ID number OPP-2003-0129, to: Public Information and Records Integrity Branch, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460-0001.  In person or by courier, bring a copy to the location of he PIRIB described in 
                    **ADDRESSES**
                    .  You may also send an electronic copy of your request via e-mail to: 
                    *opp-docket@epa.gov*.  Please use an ASCII file format and avoid the use of special characters and any form of encryption. Copies of electronic objections and hearing requests will also be accepted on disks in WordPerfect 6.1/8.0 or ASCII file format.  Do not include any CBI in your electronic copy.  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: 
                    ( print page 54650)
                    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 issue(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32). VIII.  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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, 
                    *Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use*
                     (66 FR 28355, May 22, 2001). 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 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); or 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 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.  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 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 section 408(n)(4) of FFDCA. For these same reasons, the Agency has determined that this rule does not have any “tribal  implications” as described in Executive Order 13175, entitled 
                    *Consultation and Coordination with Indian Tribal Governments*
                     (65 FR 67249, November 6, 2000).  Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.”  “Policies that have tribal implications” is defined in the Executive order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.”  This rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175.  Thus, Executive Order 13175 does not apply to this rule. IX.  Congressional Review Act 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
