    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This regulation establishes a time-limited tolerance for 
    residues of tebuconazole in or on hops. This action is in response to 
    EPA's granting of an emergency exemption under section 18 of the 
    Federal Insecticide, Fungicide, and Rodenticide Act authorizing use of 
    the pesticide on hops. This regulation establishes a maximum 
    permissible level for residues of tebuconazole in this food commodity 
    pursuant to section 408(l)(6) of the Federal Food, Drug, and Cosmetic 
    Act, as amended by the Food Quality Protection Act of 1996. The 
    tolerance will expire and is revoked on December 31, 2,000.
    
    DATES: This regulation is effective December 2, 1998. Objections and 
    requests for hearings must be received by EPA on or before February 1, 
    1999.

    SUPPLEMENTARY INFORMATION: EPA, on its own initiative, pursuant to 
    sections 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 fungicide tebuconazole in or on hops at 4.0 part per 
    million (ppm). This tolerance will expire and is revoked on December 
    31, 2,000. EPA will publish a document in the Federal Register to 
    remove the revoked tolerance from the Code of Federal Regulations.
    
    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 Federal Food, 
    Drug, and Cosmetic Act (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
    
    [[Page 66450]]
    
    safety standard and new procedures. These activities are described 
    below and discussed in greater detail in the final rule establishing 
    the time-limited tolerance associatedwith the emergency exemption for 
    use of propiconazole on sorghum (61 FR 58135, November 13, 1996)(FRL-
    5572-9).
        New 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....''
        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) of the FFDCA 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. Such tolerances can be established without providing notice 
    or period for public comment.
        Because decisions on section 18-related tolerances must proceed 
    before EPA reaches closure on several policy issues relating to 
    interpretation and implementation of the FQPA, EPA does not intend for 
    its actions on such tolerances to set binding precedents for the 
    application of section 408 and the new safety standard to other 
    tolerances and exemptions.
    
    II. Emergency Exemption for tebuconazole on hops and FFDCA 
    Tolerances
    
        The States of Idaho, Oregon, and Washington availed themselves of 
    the authority to declare a crisis exemption to use tebuconazole for 
    control of Powdery mildew (Sphaerotheca macularis) on hops. Powdery 
    mildew is a serious hop disease in many hop growing areas in the world. 
    The elimination of commercial hop production in New York during the 
    early part of this century is largely blamed on this disease. Since 
    this disease has not been observed in the Pacific Northwest until very 
    recently, no effective fungicides are registered for use on hops to 
    control it. Sulfur is the only pesticide available, but does not 
    provide effective control. The pathogen is airborne and spreads 
    quickly, primarily during the months of July and August, which are 
    critical to hop production. EPA has authorized under FIFRA section 18 
    the use of tebuconazole on hops for control of Powdery mildew 
    (Sphaerotheca macularis) in Idaho, Oregon, and Washington. After having 
    reviewed the submission, EPA concurs that emergency conditions exist 
    for this state.
        As part of its assessment of this emergency exemption, EPA assessed 
    the potential risks presented by residues of tebuconazole in or on 
    hops. In doing so, EPA considered the safety standard in FFDCA section 
    408(b)(2), and EPA decided that the necessary tolerance under FFDCA 
    section 408(l)(6) would be consistent with the safety standard and with 
    FIFRA section 18. Consistent with the need to move quickly on the 
    emergency exemption in order to address an urgent non-routine situation 
    and to ensure that the resulting food is safe and lawful, EPA is 
    issuing this tolerance without notice and opportunity for public 
    comment under section 408(e), as provided in section 408(l)(6). 
    Although this tolerance will expire and is revoked on December 31, 
    2,000, under FFDCA section 408(l)(5), residues of the pesticide not in 
    excess of the amounts specified in the tolerance remaining in or on 
    hops after that date will not be unlawful, provided the pesticide is 
    applied in a manner that was lawful under FIFRA, and the residues do 
    not exceed a level that was authorized by this tolerance at the time of 
    that application. EPA will take action to revoke this tolerance earlier 
    if any experience with, scientific data on, or other relevant 
    information on this pesticide indicate that the residues are not safe.
        Because this tolerance is being approved under emergency conditions 
    EPA has not made any decisions about whether tebuconazole meets EPA's 
    registration requirements for use on hops or whether a permanent 
    tolerance for this use would be appropriate. Under these circumstances, 
    EPA does not believe that this tolerance serves as a basis for 
    registration of tebuconazole by a State for special local needs under 
    FIFRA section 24(c). Nor does this tolerance serve as the basis for any 
    State other than Idaho, Oregon, and Washington to use this pesticide on 
    this crop under section 18 of FIFRA without following all provisions of 
    EPA's regulations implementing section 18 as identified in 40 CFR part 
    166. For additional information regarding the emergency exemption for 
    tebuconazole, contact the Agency's Registration Division at the address 
    provided above.
    
    III. Aggregate Risk Assessment and Determination of Safety
    
        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) .
        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 
    tebuconazole and to make a determination on aggregate exposure, 
    consistent with section 408(b)(2), for a time-limited tolerance for 
    residues of tebuconazole on hops at 4.0 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 tebuconazole are 
    discussed below.
        1. Acute toxicity. The acute reference dose (acute RfD) of 0.1 
    milligrams/kilogram/day (mg/kg/day) for tebuconazole was established 
    based on a developmental toxicity study in mice with a No-Observed-
    Adverse-Effect-Level (NOAEL) of 10 mg/kg/day for developmental 
    toxicity. At the Lowest-Observed-Adverse-Effect-Level (LOAEL) of 30 mg/
    kg/day, an increased incidence of runts (fetuses weighing less than 1.3 
    gram) were observed. An uncertainty
    
    [[Page 66451]]
    
    factor of 100 (10X for inter-species extrapolation and 10X for intra-
    species variability) was applied to the NOAEL of 10 mg/kg/day to 
    calculate the acute RfD of 0.1 mg/kg/day. EPA has determined that the 
    10X factor to account for enhanced susceptibility of infants and 
    children (as required by FQPA) should be retained. This determination 
    is based on the results of the developmental toxicity study in mice 
    used to establish the acute RfD, other developmental toxicity studies 
    in mice, rats and rabbits and the structural relationship of 
    tebuconazole to several other triazole pesticides which also have been 
    shown to induce developmental toxicity in rats and/or rabbits. For 
    acute dietary exposure, EPA determined that the 10X safety factor is 
    applicable to the subpopulations females (13+ years old), as well as 
    infants and children because the effects seen were developmental and 
    are presumed to occur following ``acute'' exposures. For subpopulations 
    other than females (13+ years old), infants and children, a 
    toxicological endpoint was not identified. Application of the 10X 
    safety factor for enhanced susceptibility of infants and children to 
    the acute RfD of 0.1 mg/kg/day results in an acceptable acute dietary 
    exposure (food plus water) of 10% or less of the acute RfD.
        2. Short- and intermediate-term toxicity. Toxicological endpoints 
    for short- or intermediate-term dermal toxicity were not identified. 
    Adverse systemic effects were not observed in dermal developmental 
    toxicity studies in mice or rats at the limit dose of 1,000 mg/kg/day 
    or in a 21-day dermal toxicity study in rabbits at the limit dose of 
    1,000 mg/kg/day. Therefore, risk assessments for short- or 
    intermediate-term dermal exposure were not conducted.
        A NOAEL of 0.0106 mg/liter/day (equivalent to 2.9 mg/kg/day) was 
    identified as the toxicological endpoint for short- and intermediate-
    term (and chronic) inhalation toxicity based on a 21-day inhalation 
    toxicity study in rats. At the LOAEL of 0.1558 mg/liter/day, 
    piloerection and increased liver O-demethylase and N-demethylase 
    activity were observed in both males and females. EPA determined that 
    the 10X safety factor to account for enhanced susceptibility of infants 
    and children (as required by FQPA) is not applicable for inhalation 
    toxicity for the currently registered residential exposures to 
    tebuconazole. A Margin of Exposure (MOE) of 100 or more for short- or 
    intermediate-term non-dietary risk is acceptable for all 
    subpopulations.
        3. Chronic toxicity. EPA has established a chronic RfD for 
    tebuconazole at 0.03 mg/kg/day. This RfD is based on a 1-year chronic 
    feeding study in dogs in which the NOAEL was 100 ppm (2.96 mg/kg/day in 
    males and 2.94 mg/kg/day in females) and the LOAEL was 150 ppm (4.39 
    mg/kg/day in males and 4.45 mg/kg/day in females), based on 
    histopathological changes in the adrenal gland (hypertrophy of the zona 
    fasciculata and fatty changes in the zona glomerulosa in both sexes and 
    lipid hyperplasia in the cortex in males). An uncertainty factor of 100 
    was used to account for inter-species extrapolation and intra-species 
    variability. EPA determined that the 10X factor for enhanced 
    susceptibility of infants and children (as required by FQPA) is not 
    applicable for chronic dietary exposure. A chronic dietary exposure 
    (food plus water) of 100% or less of the Chronic RfD is acceptable for 
    all subpopulations.
        4. Carcinogenicity. Tebuconazole is classified as a Group C 
    (possible human) carcinogen. This decision was primarily based on 
    results in a 91-week carcinogenicity study in mice in which the 
    following effects were observed:
        i. A statistically significant increase in the incidence of 
    hepatocellular adenomas, carcinomas and combined adenomas/carcinomas in 
    male mice at the highest dose tested (279 mg/kg/day).
        ii. A statistically significant increase in the incidence of 
    hepatocellular carcinomas and combined adenomas/carcinomas in female 
    mice at the highest dose tested (366 mg/kg/day).
    In addition, tebuconazole is structurally related to several other 
    triazole pesticides that produce similar liver tumors in mice. For the 
    purpose of carcinogenic risk assessment, the RfD methodology is used to 
    estimate human risk.
    
    B. Exposures and Risks
    
        1. From food and feed uses. Tolerances have been established (40 
    CFR 180.474) for the residues of tebuconazole, in or on a variety of 
    raw agricultural commodities. Tolerances have been established for milk 
    and meat byproducts in connection with use of tebuconazole under a 
    previous section 18. Risk assessments were conducted by EPA to assess 
    dietary exposures and risks from tebuconazole as follows:
        i.  Acute exposure and risk. 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 1 day or single exposure. An acute dietary endpoint of concern was 
    identified for subpopulations females (13+ years old), as well as 
    infants and children. For acute dietary exposure, EPA determined that 
    the 10X safety factor for enhanced susceptibility of infants and 
    children (as required by FQPA) is applicable to all of these 
    subpopulations. Application of the 10X safety factor for enhanced 
    susceptibility of infants and children to the acute RfD of 0.1 mg/kg/
    day results in an acceptable acute dietary exposure (food plus water) 
    of 10% or less of the acute RfD.
        An acute dietary (food only) probablistic risk analysis submitted 
    in conjunction with another action was used to estimate acute dietary 
    risk. The following assumptions were utilized in the Monte Carlo 
    analysis: (a) Percent crop treated data were used for all commodities; 
    (b) maximum residue levels from crop field trials for single serving 
    commodities such as bananas and peaches were utilized; (c) average 
    residue levels from crop field trials were used for blended commodities 
    such as fruit juices, grains and oils; (d) anticipated residue levels 
    for ruminant commodities were calculated using a livestock diet 
    constructed using anticipated residue levels for livestock feed items. 
    This analysis should be considered highly refined. This analysis was 
    run with 2,000 iterations. The results of the Monte Carlo analysis 
    indicate that the percent of acute RfD for all children and infants 
    subgroups as well as females 13+ years old are all below 10% of the 
    RfD: nursing infants (< 1="" year="" old),="" 7%;="" non-nursing="" infants="">< 1="" year="" old),="" 7%;="" children="" (1="" to="" 6="" years="" old)="" 9%,="" children="" (7="" to="" 12="" years="" old)="" 3%;="" all="" infants="">< 1="" year="" old),="" 7%;="" females="" (13="" years="" plus="" old),="" 3%.="" ii.="" chronic="" exposure="" and="" risk.="" the="" agency="" conducted="" a="" chronic="" dietary="" exposure="" analysis="" and="" risk="" assessment.="" the="" analysis="" evaluated="" individual="" food="" consumption="" as="" reported="" by="" respondents="" in="" the="" usda="" 1977-78="" nationwide="" food="" consumption="" survey="" (nfcs)="" and="" accumulates="" exposure="" to="" the="" chemical="" for="" each="" commodity.="" in="" conducting="" the="" chronic="" dietary="" risk="" assessment,="" the="" agency="" made="" very="" conservative="" assumptions="" (100%="" of="" hops,="" pistachios="" and="" wheat="" and="" all="" other="" commodities="" having="" tebuconazole="" tolerances="" will="" contain="" residues="" and="" those="" residues="" will="" be="" at="" tolerance="" level)="" which="" results="" in="" an="" overestimation="" of="" human="" dietary="" exposure.="" thus,="" in="" making="" a="" safety="" determination="" for="" these="" tolerances,="" the="" agency="" is="" taking="" into="" account="" this="" conservative="" exposure="" assessment.="" the="" existing="" tebuconazole="" tolerances="" (published,="" pending,="" and="" including="" the="" necessary="" section="" 18="" tolerance(s))="" result="" [[page="" 66452]]="" in="" a="" theoretical="" maximum="" residue="" contribution="" (tmrc)="" that="" is="" equivalent="" to="" percentages="" of="" the="" rfd="" below="" 100%="" for="" all="" subgroups="" (i.e.,="" u.s.="" population,="" 11%="" and="" non-nursing="" infants="">< 1="" year="" old),="" the="" most="" highly="" exposed="" subgroup,="" 37%).="" 2.="" from="" drinking="" water.="" based="" on="" present="" data="" in="" the="" agency="" files,="" tebuconazole="" is="" persistent="" and="" relatively="" immobile.="" there="" are="" no="" established="" maximum="" contaminant="" level="" or="" health="" advisory="" levels="" for="" residues="" of="" tebuconazole="" in="" drinking="" water.="" monitoring="" data="" for="" residues="" of="" tebuconazole="" in="" surface="" and="" ground="" water="" are="" not="" available.="" tebuconazole="" is="" not="" included="" in="" the="" pesticides="" in="" ground="" water="" database="" (usepa,="" 1992),="" and="" it="" was="" not="" an="" analyte="" in="" the="" national="" pesticide="" survey="" (usepa,="" 1990).="" epa="" estimated="" exposure="" for="" tebuconazole="" for="" both="" surface="" and="" ground="" water="" based="" on="" available="" modeling.="" environmental="" concentrations="" for="" surface="" water="" were="" estimated="" using="" modeling="" from="" geneec="" (generic="" estimated="" environmental="" concentration).="" for="" surface="" water,="" the="" maximum="" concentrations="" were="" used="" for="" acute="" risk="" calculations,="" the="" annual="" means="" (1-10="" years="" old)="" for="" chronic="" risk="" calculations.="" current="" agency="" policy="" allows="" that="" a="" factor="" of="" 3="" be="" applied="" to="" geneec="" model="" values="" when="" determining="" whether="" or="" not="" a="" level="" of="" concern="" has="" been="" exceeded.="" if="" the="" geneec="" model="" value="" is=""> 3 times the drinking water level of 
    concern (DWLOC), the pesticide is considered to have passed the screen. 
    Acute and chronic ground water concentrations were estimated using the 
    SCI-GROW (Screening Concentration in Ground Water) model. For the 
    purposes of the screening level assessment, the maximum and average 
    annual concentrations in ground water are not believed to vary 
    significantly. DWLOCs will be compared directly to values.
        i. Acute exposure and risk. DWLOCs were calculated for acute 
    exposures to tebuconazole in surface and ground water for females 13+ 
    years old and children (1-6 years old). Relative to an acute toxicity 
    endpoint, the acute dietary food exposure (from the probablistic 
    analysis) was subtracted from the ratio of the acute NOAEL to the 
    appropriate percentage acute RfD to obtain the acceptable acute 
    exposure to tebuconazole in drinking water. DWLOCs were then calculated 
    from this acceptable exposure using default body weights (60 kg for 
    females and 10 kg for children) and drinking water consumption figures 
    (2 liters for females and 1 liter for children). Based on these 
    calculations EPA's DWLOC for acute dietary risk is 14 parts per billion 
    (ppb) for children (1-6 years old) and 200 ppb for females 13+ years 
    old.
        Maximum concentrations of tebuconazole in surface and ground water 
    are estimated to be 14 ppb and 0.3 ppb, respectively. The maximum 
    estimated concentrations of tebuconazole in surface and ground water 
    are less than EPA's levels of concern for acute exposure in drinking 
    water for the females 13+ and children.
        ii. Chronic exposure and risk. EPA has calculated DWLOCs for 
    chronic exposures to tebuconazole in surface and ground water. To 
    calculate the DWLOC for chronic exposures relative to a chronic 
    toxicity endpoint, the chronic dietary food exposure was subtracted 
    from the chronic RfD (0.03 mg/kg/day) to obtain the acceptable chronic 
    exposure to tebuconazole in drinking water. DWLOCs were then calculated 
    from this exposure using default body weights (70 kg for U.S. 
    population, 60 kg for females and 10 kg for children) and drinking 
    water consumption figures (2 liters U.S. population and females and 1 
    liter children). Based on these calculations EPA's DWLOCs for chronic 
    risk are 950 ppb for the U.S. population, 780 ppb for females and 190 
    ppb for non-nursing infants (< 1="" year="" old).="" estimated="" annual="" average="" concentrations="" of="" tebuconazole="" in="" surface="" water="" and="" ground="" water="" are="" 10="" ppb="" and="" 0.3="" ppb,="" respectively.="" the="" estimated="" annual="" average="" concentrations="" of="" tebuconazole="" in="" surface="" and="" ground="" water="" are="" less="" than="" epa's="" levels="" of="" concern="" for="" chronic="" exposure="" in="" drinking="" water.="" 3.="" from="" non-dietary="" exposure.="" no="" short-="" or="" intermediate-term="" dermal=""

    VIII. Regulatory Assessment Requirements
    
    A. Certain Acts and Executive Orders
    
        This final rule establishes a tolerance under FFDCA section 408 
    (l)(6). 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) (Pub. L. 104-4). Nor does it require any 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 in 
    accordance with Executive Order 13045, entitled Protection of Children 
    from Environmental Health Risks and Safety Risks (62 FR 19885, April 
    23, 1997).
        In addition, since tolerances and exemptions that are established 
    under FFDCA section 408 (l)(6), 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. Nevertheless, the Agency has previously assessed whether 
    establishing tolerances, exemptions from tolerances, raising tolerance 
    levels or expanding exemptions might adversely impact small entities 
    and concluded, as a generic matter, that there is no adverse economic 
    impact. The factual basis for the Agency's generic certification for 
    tolerance acations published on May 4, 1981 (46 FR 24950), and was 
    provided to the Chief Counsel for Advocacy of the Small Business 
    Administration.
    
    B. Executive Order 12875
    
        Under Executive Order 12875, entitled Enhancing the 
    Intergovernmental Partnership (58 FR 58093, October 28, 1993), EPA may 
    not issue a regulation that is not required by statute and that creates 
    a mandate upon a State, local, or tribal government, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by those governments. If the mandate is unfunded, EPA 
    must provide to OMB a description of the extent of EPA's prior 
    consultation with representatives of affected State, local, and tribal 
    governments, the nature of their concerns, copies of any written 
    communications from the governments, and a statement supporting the 
    need to issue the regulation. In addition, Executive Order 12875 
    requires EPA to develop an effective process permitting elected 
    officials and other representatives of State, local, and tribal 
    governments ``to provide meaningful and timely input in the development 
    of regulatory proposals containing significant unfunded mandates.''
        Today's rule does not create an unfunded Federal mandate on State, 
    local, or tribal governments. The rule does not impose any enforceable 
    duties on these entities. Accordingly, the requirements of section 1(a) 
    of Executive Order 12875 do not apply to this rule.
    
    C. Executive Order 13084
    
        Under Executive Order 13084, entitled Consultation and Coordination 
    with Indian Tribal Governments (63 FR 27655, May 19,1998), EPA may not 
    issue a regulation that is not required by statute, that significantly 
    or uniquely affects the communities of Indian tribal governments, and 
    that imposes substantial direct compliance costs on those communities, 
    unless the Federal government provides the funds necessary to pay the 
    direct compliance costs incurred by the tribal governments. If the 
    mandate is unfunded, EPA must provide to OMB, in a separately 
    identified section of the preamble to the rule, a description of the 
    extent of EPA's prior consultation with representatives of affected 
    tribal governments, a summary of the nature of their concerns, and a 
    statement supporting the need to issue the regulation. In addition, 
    Executive Order 13084 requires EPA to develop an effective process 
    permitting elected officials and other representatives of Indian tribal 
    governments ``to provide meaningful and timely input in the development 
    of regulatory policies on matters that significantly or uniquely affect 
    their communities.''
        Today's rule does not significantly or uniquely affect the 
    communities of Indian tribal governments. This action does not involve 
    or impose any requirements that affect Indian tribes. Accordingly, the 
    requirements of section 3(b) of Executive Order 13084 do not apply to 
    this rule.
    
    IX. 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
    
    [[Page 66456]]
    
    report containing this rule and other required information to the U.S. 
    Senate, the U.S. House of Representatives, and the Comptroller General 
    of the United States prior to publication of the rule in the Federal 
    Register. This rule is not a ``major rule'' as defined by 5 U.S.C. 
    804(2).
