    -----------------------------------------------------------------------
    
    SUMMARY: This regulation establishes a time-limited tolerance for 
    combined residues of the insecticide tebufenozide in or on the raw 
    agricultural commodities peppers, non-brassica leafy vegetables (Crop 
    Group 4 - celery, lettuce, spinach, swiss chard), turnips grown for 
    foliage tops only, and brassica (cole) leafy vegetables (Crop Group 5 - 
    broccoli, cabbage, cauliflower, collards, kale, kohlrabi, and mustard 
    greens) in connection with EPA's granting of emergency exemptions under 
    section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act 
    authorizing use of tebufenozide on peppers, leafy vegetables (except 
    brassica), turnips grown for foliage tops only and brassica leafy 
    vegetables in Texas; and lettuce, broccoli, cauliflower, cabbage and 
    spinach in Arizona. This regulation establishes maximum permissible 
    levels for residues of tebufenozide in these foods. These tolerances 
    will expire on February 28, 1998.

    SUPPLEMENTARY INFORMATION: EPA, pursuant to section 408(e) and (l)(6) 
    of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(e) 
    and (l)(6), is establishing a tolerance for residues of the insecticide 
    tebufenozide (benzoic acid, 3,5-dimethyl-1-(1,1-dimethylethyl)-2-(4-
    ethylbenzoyl)hydrazide) in or on peppers at 0.5 part per million (ppm), 
    leafy vegetables (except brassica) at 5.0 ppm, turnip tops at 5.0 ppm, 
    and brassica (cole) leafy vegetables at 5.0 ppm. These tolerances will 
    expire on February 28, 1998.
    
    I. Background and Statutory Authority
    
        The Food Quality Protection Act of 1996 (FQPA) (Pub. L. 104-170) 
    was signed into law August 3, 1996. FQPA amends both the FFDCA, 21 
    U.S.C. 301 et seq., and the Federal Insecticide, Fungicide, and 
    Rodenticide Act (FIFRA), 7 U.S.C. 136 et seq. The FQPA amendments went 
    into effect immediately. Among other things, FQPA amends FFDCA to bring 
    all EPA pesticide tolerance-setting activities under a new section 408 
    with a new safety standard and new procedures. These activities were 
    discussed in detail in the final rule establishing the time-limited 
    tolerance for an emergency exemption for use of propiconazole on 
    sorghum (61 CFR 58135, November 13, 1996)(FRL-5572-9).
        New section 408(b)(2)(A)(i) 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, 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....''
        Section 18 of FIFRA authorizes EPA to exempt any Federal or State 
    Agency from any provision of FIFRA, if EPA determines that ``emergency 
    conditions exist which require such exemption.'' This provision was not 
    amended by FQPA. EPA has established regulations governing such 
    emergency exemptions in 40 CFR part 166.
        Section 408(l)(6) requires EPA to establish a time-limited 
    tolerance or exemption from the requirement for a tolerance for 
    pesticide chemical residues in food that will result from the use of a 
    pesticide under an emergency exemption granted by EPA under section 18 
    of FIFRA. Section 408(l)(6) also requires EPA to promulgate regulations 
    by August 3, 1997, governing the establishment of tolerances and 
    exemptions under section 408(l)(6) and requires that the
    
    [[Page 9985]]
    
    regulations be consistent with section 408(b)(2) and (c)(2) and FIFRA 
    section 18.
        Section 408(l)(6) allows EPA to establish tolerances or exemptions 
    from the requirement for a tolerance, in connection with EPA's granting 
    of FIFRA section 18 emergency exemptions, without providing notice or a 
    period for public comment. Thus, consistent with the need to act 
    expeditiously on requests for emergency exemptions under FIFRA, EPA can 
    establish such tolerances or exemptions under the authority of section 
    408(e) and (l)(6) without notice and comment rulemaking.
        In establishing section 18-related tolerances and exemptions during 
    this interim period before EPA issues the section 408(l)(6) procedural 
    regulation and before EPA makes its broad policy decisions concerning 
    the interpretation and implementation of the new section 408, EPA does 
    not intend to set precedents for the application of section 408 and the 
    new safety standard to other tolerances and exemptions. Rather, these 
    early section 18 tolerance and exemption decisions will be made on a 
    case-by-case basis and will not bind EPA as it proceeds with further 
    rulemaking and policy development. EPA intends to act on section 18-
    related tolerances and exemptions that clearly qualify under the new 
    law.
    
    II. Emergency Exemptions for Tebufenozide on Peppers, Leafy 
    Vegetables (except Brassica), Turnip Tops, and Cole Leafy 
    Vegetables (Brassica) and FFDCA Tolerances
    
        On December 18, and 20, 1996, the Texas Department of Agriculture 
    availed of itself the authority to declare the existence of a crisis 
    situation within the State, thereby authorizing use under FIFRA section 
    18 of tebufenozide on leafy vegetables (non-brassica), turnip tops and 
    brassica leafy vegetables to control the beet armyworm (BAW), 
    respectively. The states of Texas and Arizona have also requested 
    specific exemptions for use of this chemical to control beet armyworm 
    on brassica and non-brassica leafy vegetable, turnip tops and peppers. 
    Emergency conditions are determined to exist due to: (1) The BAW 
    populations demonstrating resistance to registered insecticides causing 
    control failures when these products are applied to BAW; (2) a mild 
    winter and unusually dry, hot weather have increased the survival rate 
    of the pest. Natural controls, such as disease, needed cooler, wetter 
    conditions to have their greatest impact on this pest; and (3) the 
    unusually large numbers of BAW. According to the Applicant, estimated 
    yield losses due to BAW in peppers and non-brassica leafy vegetables 
    could result in a 50% yield loss and a 30% yield for brassica (cole) 
    leafy vegetables without the use of an effective pesticide.
        As part of its assessment of these applications for emergency 
    exemption, EPA assessed the potential risks presented by residues of 
    tebufenozide on brassica (cole), non-brassica leafy vegetables, turnip 
    tops and peppers. In doing so, EPA considered the new safety standard 
    in FFDCA section 408(b)(2), and EPA decided to grant the section 18 
    exemptions only after concluding that the necessary tolerance under 
    FFDCA section 408(l)(6) would clearly be consistent with the new safety 
    standard and with FIFRA section 18. This tolerance for tebufenozide 
    will permit the marketing of brassica (cole) and non-brassica leafy 
    vegetables, turnip tops and peppers treated in accordance with the 
    provisions of the section 18 emergency exemptions. Consistent with the 
    need to move quickly on the emergency exemptions and to ensure that the 
    resulting food is safe and lawful, EPA is issuing these tolerances 
    without notice and opportunity for public comment under section 408(e) 
    as provided in section 408(l)(6). Although these tolerances will expire 
    on February 28, 1998, under FFDCA section 408(l)(5), residues of 
    tebufenozide not in excess of the amount specified in the tolerance 
    remaining in or on brassica (cole) , and non-brassica leafy vegetables, 
    turnip tops and peppers after that date will not be unlawful, provided 
    the pesticide is applied during the term of, and in accordance with all 
    the conditions of, the emergency exemptions. EPA will take action to 
    revoke these tolerances earlier if any experience with, scientific data 
    on, or other relevant information on this pesticide indicate that the 
    residues are not safe.
        EPA has not made any decisions about whether tebufenozide meets the 
    requirements for registration under FIFRA section 3 for use on brassica 
    (cole) and non-brassica leafy vegetables, turnip tops and peppers or 
    whether a permanent tolerance for tebufenozide on these crops would be 
    appropriate. This action by EPA does not serve as a basis for 
    registration of tebufenozide by a State for special local needs under 
    FIFRA section 24(c). Nor does this action serve as the basis for any 
    State other than Texas or Arkansas to use this product on this crop 
    under section 18 of FIFRA without following all provisions of section 
    18 as identified in 40 CFR 180.166. For additional information 
    regarding the emergency exemptions for tebufenozide, contact the 
    Agency's Registration Division at the address provided above.
    
    III. Risk Assessment and Statutory Findings
    
        EPA performs a number of analyses to determine the risks from 
    aggregate exposure to pesticide residues. First, EPA determines the 
    toxicity of pesticides based primarily on toxicological studies using 
    laboratory animals. These studies address many adverse health effects, 
    including (but not limited to) reproductive effects, developmental 
    toxicity, toxicity to the nervous system, and carcinogenicity. For many 
    of these studies, a dose response relationship can be determined, which 
    provides a dose that causes adverse effects (threshold effects) and 
    doses causing no observed effects (the ``no-observed effect level'' or 
    ``NOEL'').
        Once a study has been evaluated and the observed effects have been 
    determined to be threshold effects, EPA generally divides the NOEL from 
    the study with the lowest NOEL by an uncertainty factor (usually 100 or 
    more) to determine the Reference Dose (RfD). The RfD is a level at or 
    below which daily aggregate exposure over a lifetime will not pose 
    appreciable risks to human health. An uncertainty factor (sometimes 
    called a ``safety factor'') of 100 is commonly used since it is assumed 
    that people may be up to 10 times more sensitive to pesticides than the 
    test animals, and that one person or subgroup of the population (such 
    as infants and children) could be up to 10 times more sensitive to a 
    pesticide than another. In addition, EPA assesses the potential risks 
    to infants and children based on the weight of the evidence of the 
    toxicology studies and determines whether an additional uncertainty 
    factor is warranted. Thus, an aggregate daily exposure to a pesticide 
    residue at or below the RfD (expressed as 100 percent or less of the 
    RfD) is generally considered by EPA to pose no appreciable risk.
        Lifetime feeding studies in two species of laboratory animals are 
    conducted to screen pesticides for cancer effects. When evidence of 
    increased cancer is noted in these studies, the Agency conducts a 
    weight of the evidence review of all relevant toxicological data 
    including short term and mutagenicity studies and structure activity 
    relationship. Once a pesticide has been classified as a potential human 
    carcinogen, different types of risk assessments (e.g., linear low dose 
    extrapolations or margin of exposure calculation based on the 
    appropriate
    
    [[Page 9986]]
    
    NOEL) will be carried out based on the nature of the carcinogenic 
    response and the Agency's knowledge of its mode of action.
        In examining aggregate exposure, FFDCA section 408 requires that 
    EPA take into account available and reliable information concerning 
    exposure from the pesticide residue in the food in question, residues 
    in other foods for which there are tolerances, and other non-
    occupational exposures, such as where residues leach into groundwater 
    or surface water that is consumed as drinking water. Dietary exposure 
    to residues of a pesticide in a food commodity are estimated by 
    multiplying the average daily consumption of the food forms of that 
    commodity by the tolerance level or the anticipated pesticide residue 
    level. The Theoretical Maximum Residue Contribution (TMRC) is an 
    estimate of the level of residues consumed daily if each food item 
    contained pesticide residues equal to the tolerance. The TMRC is a 
    ``worst case'' estimate since it is based on the assumptions that food 
    contains pesticide residues at the tolerance level and that 100 percent 
    of the crop is treated by pesticides that have established tolerances. 
    If the TMRC exceeds the RfD or poses a lifetime cancer risk that is 
    greater than approximately one in a million, EPA attempts to derive a 
    more accurate exposure estimate for the pesticide by evaluating 
    additional types of information (anticipated residue data and/or 
    percent of crop treated data) which show, generally, that pesticide 
    residues in most foods when they are eaten are well below established 
    tolerances.
    
    IV. Aggregate Risk Assessments, Cumulative Risk Discussion, 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. Tebufenozide is not registered by EPA for indoor or 
    outdoor residential use. Existing food and feed use tolerances for 
    tebufenozide are listed in 40 CFR 180.482. At this time EPA is not in 
    possession of a registration application for tebufenozide on brassica 
    (cole) and non-brassica leafy vegetables, turnip tops, and peppers. 
    However, based on the information submitted to the Agency thus far, EPA 
    has sufficient data to assess the hazards of tebufenozide and to make a 
    determination on aggregate exposure, consistent with section 408(b)(2), 
    for the time-limited tolerances for residues of tebufenozide on 
    brassica (cole) leafy vegetables at 5.0 ppm, non-brassica leafy 
    vegetables at 5.0 ppm, turnip tops at 5.0 ppm and peppers at 0.5 ppm. 
    EPA's assessment of the dietary exposures and risks associated with 
    establishing these tolerances follows.
    
    A. Toxicological Profile
    
        1. Chronic toxicity. Based on the available chronic toxicity data, 
    the EPA's Office of Pesticide Programs (OPP) has established the RfD 
    for tebufenozide at 0.018 milligrams/kilogram/day (mg/kg/day). The RfD 
    is based on a 1-year feeding study in dogs with a NOEL of 1.8 mg/kg/day 
    and an uncertainty factor of 100. Decreased red blood cells, 
    hematocrit, and hemoglobin and increased heinz bodies, reticulocytes, 
    and platelets were observed at the Lowest-Observed Effect Level (LOEL) 
    of 8.7 mg/kg/day.
        2. Acute toxicity. No appropriate acute dietary endpoint was 
    identified by OPP. This risk assessment is not required.
        3. Carcinogenicity. Using its Guidelines for Carcinogen Risk 
    Assessment published September 24, 1986 (51 FR 33992), OPP has 
    classified tebufenozide as a Group ``E'' chemical (no evidence of 
    carcinogenicity for humans) based on the results of carcinogenicity 
    studies in two species. There was no evidence of carcinogenicity in a 
    2-year rat study and an 18-month mouse study.
    
    B. Aggregate Exposure
    
        Tolerances for residues of tebufenozide are currently expressed as 
    benzoic acid, 3,5-dimethyl-1-(1,1-dimethylethyl)-2-(4-
    ethylbenzoyl)hydrazide. Permanent tolerances currently exist for 
    residues on apples and walnuts (see 40 CFR 180.482).
        For purposes of assessing the chronic dietary exposure from 
    tebufenozide, EPA assumed tolerance level residues and 100 percent of 
    crop treated refinements to estimate the TMRC from all established 
    existing food uses for tebufenozide as well as the proposed use on 
    leafy vegetables, turnip tops and peppers. Neither peppers nor any of 
    the commodities comprising Crop Group 4 (Non-brassica leafy vegetables) 
    and 5 (Brassica Cole Leafy vegetables) are considered livestock feed 
    items; thus, there is no reasonable expectation that measurable 
    residues of tebufenozide will occur in meat, milk, poultry, or eggs 
    under the terms of these emergency exemptions. Although, turnip tops 
    potentially are a ruminant feed item, conversation with the Texas 
    Department of Agriculture indicates that the turnip tops treated under 
    this section 18 are destined for fresh market use only. Nonetheless, 
    even if those turnip tops were fed to ruminants, potential residue 
    levels in animal commodities would most likely be undetectable. For 
    purposes of this section 18 registration only, OPP concludes that 
    tolerances for animal commodities are not needed.
        Other potential sources of exposure of the general population to 
    residues of pesticides are residues in drinking water and exposure from 
    non-occupational sources. Based on the available studies used in EPA's 
    assessment of environmental risk, tebufenozide is moderately persistent 
    to persistent and mobile, and could potentially leach to groundwater 
    and runoff to surface water under certain environmental conditions. 
    There are no established Maximum Concentration Levels for residues of 
    tebufenozide in drinking water. No drinking water health advisory 
    levels have been established for tebufenozide. There is no entry for 
    tebufenozide in the ``Pesticides in Groundwater Database'' (EPA 734-12-
    92-001, September 1992).
        The Agency does not have available data to perform a quantitative 
    drinking water risk assessment for tebufenozide at this time. However, 
    in order to mitigate the potential for tebufenozide to leach into 
    groundwater or runoff to surface water, precautionary language has been 
    incorporated into the product label.
        Because the Agency lacks sufficient water-related exposure data to 
    complete a comprehensive drinking water risk assessment for many 
    pesticides, EPA has commenced and nearly completed a process to 
    identify a reasonable yet conservative bounding figure for the 
    potential contribution of water-related exposure to the aggregate risk 
    posed by a pesticide. In developing the bounding figure, EPA estimated 
    residue levels, in water for a number of specific pesticides using 
    various data sources. The Agency then applied the estimated residue 
    levels, in conjunction with appropriate toxicological endpoints (RFD's 
    or acute dietary NOEL's) and assumptions about body weight and 
    consumption, to calculate, for each pesticide, the increment of 
    aggregate risk contributed by consumption of contaminated water. While 
    EPA has not yet pinpointed the appropriate bounding figure for 
    consumption of contaminated water, the ranges the Agency is continuing 
    to examine are all below the level that would cause tebufenozide to 
    exceed the RFD if the tolerance being considered in this document were 
    granted. The Agency has therefore concluded that the potential 
    exposures associated with tebufenozide in water, even at the higher 
    levels the Agency is considering
    
    [[Page 9987]]
    
    as a conservation upper bound, would not prevent the Agency from 
    determining that there is a reasonable certainty of no harm if the 
    tolerance is granted.
        Tebufenozide is not registered for either indoor or outdoor 
    residential use. Non-occupational exposure to the general population is 
    therefore not expected and not considered in aggregate exposure 
    estimates.
    
    C. Cumulative Exposure to Substances with Common Mechanisms 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.'' The Agency believes that ``available 
    information'' in this context might include not only toxicity, 
    chemistry, and exposure data, but also policies and methodologies for 
    conducting cumulative risk assessments. While the Agency has some 
    information in its files that may turn out to be helpful in eventually 
    determining whether a pesticide shares a common mechanism of toxicity 
    with any other substances, EPA does not at this time have the 
    methodology to fully resolve the scientific issues concerning common 
    mechanism of toxicity in a meaningful way. EPA has begun a pilot 
    process to study this issue further through the examination of 
    particular classes of pesticides. The Agency hopes that the results of 
    this pilot process will enable the Agency to apply common mechanism 
    issues to its pesticide risk assessments. At present, however, the 
    Agency does not know how to apply the information in its files 
    concerning common mechanism issues to most risk assessments.
        In making individual tolerance decisions, the Agency will determine 
    whether:
        1. It has sufficient information to determine that a pesticide does 
    not appear to share a common mechanism of toxicity with other 
    substances.
        2. It is unable to conclude that a pesticide does not share a 
    common mechanism of toxicity with other substances.
        For pesticides falling into the first category, the Agency will 
    explain its determination and factor the determination into the 
    tolerance decision. For pesticides falling into the second category, 
    the Agency will conclude that it does not have sufficient available 
    information concerning common mechanism of toxicity to scientifically 
    apply that information to the tolerance decision, the tolerance 
    decision will be reached based upon the best available and useful 
    information for the individual chemical, and a risk assessment will be 
    performed for the individual chemical assuming that no common mechanism 
    of toxicity exists. However, tolerance decisions falling into the 
    second category will be reexamined by the Agency after EPA establishes 
    methodologies and procedures for integrating information concerning 
    common mechanism into its risk assessments. In such circumstances, 
    related registration actions may be conditioned upon the provision of 
    such data as may be necessary to evaluate common mechanism of toxicity 
    issues in a risk assessment.
        Tebufenozide falls into the second category and at this time, the 
    Agency has not made a determination that tebufenozide and other 
    substances that may have a common mode of toxicity would have 
    cumulative effects. EPA has not yet determined whether to include this 
    chemical in a cumulative risk assessment. This tolerance determination 
    does not take into account common mechanism issues. The Agency will 
    reexamine tolerances for tebufenozide, after the Agency has developed a 
    methodology for applying common mechanism of toxicity issues to risk 
    assessments.
        Given the time limited nature of this request, the need to make 
    emergency exemption decisions quickly, and the significant scientific 
    uncertainty at this time about how to define common mode of toxicity, 
    the Agency will make its safety determination for these tolerances 
    based on those factors which it can reasonably integrate into a risk 
    assessment. For purposes of these tolerances only, the Agency is 
    considering only the potential risks of tebufenozide in its aggregate 
    exposure.
    
    D. Safety Determinations for U.S. Population
    
        EPA has concluded that chronic dietary exposure to tebufenozide 
    will utilize 27% of the RfD for the U.S. population. EPA generally has 
    no concern for exposures below 100 percent of the RfD because the RfD 
    represents the level at or below which daily aggregate dietary exposure 
    over a lifetime will not pose appreciable risks to human health. 
    Despite the potential for exposure to tebufenozide in drinking water, 
    EPA does not expect the aggregate exposure to exceed 100% of the RfD. 
    EPA concludes that there is a reasonable certainty that no harm will 
    result from aggregate exposure to tebufenozide residues.
    
    E. Determination of Safety for Infants and Children
    
        In assessing the potential for additional sensitivity of infants 
    and children to residues of tebufenozide, EPA considered data from 
    developmental toxicity studies in the rat and rabbit and a reproduction 
    study in the rat. The developmental toxicity studies are designed to 
    evaluate adverse effects on the developing organism resulting from 
    pesticide exposure during prenatal development to one or both parents. 
    Reproduction studies provide information relating to effects from 
    exposure to the pesticide on the reproductive capability of mating 
    animals and data on systemic toxicity.
        Developmental (pre-natal) toxicity was not observed in 
    developmental studies using rats and rabbits. The NOEL for 
    developmental effects in both rats and rabbits was >1,000 mg/kg/day the 
    highest dose tested (HDT), which demonstrates that no toxicity was 
    present for tebufenozide.
        In the two-generation reproductive toxicity study in the rat, the 
    reproductive/developmental toxicity NOEL of 12.1 mg/kg/day was 14-fold 
    higher than the parental (systemic) toxicity NOEL (0.85 mg/kg/day), 
    which indicates that post-natal toxicity in the production studies 
    occurs only in the presence of significant parental toxicity.
        These developmental and reproduction studies indicate that 
    tebufenozide does not have additional sensitivity for infants and 
    children in comparison to other exposed groups. The TMRC value for the 
    most highly exposed infant and children subgroup (non-nursing infants 
    <1 year="" old)="" occupies="" 61%="" of="" the="" rfd.="" however,="" this="" calculation="" assumes="" 100%="" crop="" treated="" and="" uses="" tolerance="" level="" residues="" for="" all="" commodities.="" refinement="" of="" the="" dietary="" risk="" assessment="" by="" using="" percent="" crop="" treated="" and="" anticipated="" residue="" data="" would="" greatly="" reduce="" dietary="" exposure.="" therefore,="" this="" risk="" assessment="" is="" an="" over-estimate="" of="" dietary="" risk.="" consideration="" of="" anticipated="" residues="" and="" percent="" crop="" treated="" would="" likely="" result="" in="" an="" anticipated="" residue="" contribution="" (arc)="" which="" would="" occupy="" a="" percent="" of="" the="" rfd="" that="" is="" likely="" to="" be="" significantly="" lower="" than="" the="" currently="" calculated="" tmrc="" value.="" therefore,="" taking="" into="" account="" the="" completeness="" and="" reliability="" of="" the="" toxicity="" data="" and="" the="" conservative="" exposure="" assessment,="" epa="" concludes="" that="" there="" is="" a="" reasonable="" certainty="" that="" no="" harm="" will="" result="" to="" infants="" and="" children="" from="" aggregate="" exposure="" to="" tebufenozide="" residues.="" [[page="" 9988]]="" ffdca="" section="" 408="" provides="" that="" epa="" shall="" apply="" an="" additional="" safety="" factor="" for="" infants="" and="" children="" in="" the="" case="" of="" threshold="" effects="" to="" account="" for="" pre-="" and="" post-natal="" toxicity="" and="" the="" completeness="" of="" the="" data="" base="" unless="" epa="" concludes="" that="" a="" different="" margin="" of="" safety="" is="" appropriate.="" epa="" has="" concluded="" that="" the="" database="" on="" this="" pesticide="" is="" sufficiently="" complete="" regarding="" potential="" effects="" on="" infants="" and="" children="" and="" that="" the="" studies="" demonstrate="" no="" additional="" sensitivity="" in="" infants="" and="" children.="" therefore,="" epa="" concludes="" that="" an="" additional="" uncertainty="" factor="" is="" not="" warranted="" and="" that="" the="" rfd="" at="" 0.018="" mg/kg/day="" based="" on="" a="" 100-fold="" safety="" is="" adequate="" for="" protecting="" infants="" and="" children.="" v.="" other="" considerations="" the="" metabolism="" of="" tebufenozide="" in="" plants="" is="" adequately="" understood="" for="" the="" purposes="" of="" this="" tolerance.="" there="" are="" no="" mexican,="" canadian="" or="" codex="" international="" maximum="" residue="" levels="" established="" for="" residues="" of="" tebufenozide.="" there="" is="" a="" practical="" analytical="" method="" (liquid="" chromatography="" with="" ultraviolet="" detection)="" for="" detecting="" and="" measuring="" levels="" of="" tebufenozide="" in="" or="" on="" food="" with="" a="" limit="" of="" detection="" that="" allows="" monitoring="" of="" food="" with="" residues="" at="" or="" above="" the="" level="" set="" by="" the="" tebufenozide="" tolerance.="" epa="" has="" provided="" information="" on="" this="" method="" to="" fda.=""

        The official record for this rulemaking, as well as the public 
    version, as described above, is kept in paper form. Accordingly, in the 
    event there are objections and hearing requests, EPA will transfer any 
    copies of objections and hearing requests received electronically into 
    printed, paper form as they are received and will place the paper 
    copies in the official rulemaking record. The official rulemaking 
    record is the paper record maintained at the Virginia address in `` 
    ADDRESSES'' at the beginning of this document.
    
    IX. Regulatory Assessment Requirements
    
        Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
    action is not a ``significant regulatory action'' and, since this 
    action does not impose any information collection requirements as 
    defined by the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., it is 
    not subject to review by the Office of Management and Budget. In 
    addition, this action does not impose any enforceable duty or contain 
    any unfunded mandate as described in the Unfunded Mandates Reform Act 
    of 1995 (Pub. L. 104-4), or require prior consultation with State 
    officials as specified by Executive Order 12875 (58 FR 58093, October 
    28, 1993), or special considerations as required by Executive Order 
    12898 (59 FR 7629, February 16, 1994).
        Because FFDCA section 408(l)(6) permits establishment of this 
    regulation without a notice of proposed rulemaking, the regulatory 
    flexibility analysis requirements of the Regulatory Flexibility Act, 5 
    U.S.C. 604(a), do not apply.
        Under 5 U.S.C. 801(a)(1)(A) of the Administrative Procedure Act 
    (APA) as amended by the Small Business Regulatory Enforcement Fairness 
    Act of 1996 (Title II of Pub. L. 104-121, 110 Stat. 847), EPA submitted 
    a report containing this rule and other required information to the 
    U.S. Senate, the U.S. House of Representatives and the
    
    [[Page 9989]]
    
    Comptroller General of the General Accounting Office prior to 
    publication of the rule in today's Federal Register. This rule is not a 
    ``major rule'' as defined by 5 U.S.C. 804(2) of the APA as amended.
