    Azoxystrobin; Pesticide Tolerances for Emergency Exemptions
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This regulation establishes a time-limited tolerance for 
    combined residues or residues of azoxystrobin or methyl (E)-2-[2-[6-(2-
    cyanophenoxy)pyrimidin-4-yloxy]phenyl]-3-methoxyacrylate) and its Z 
    isomer in or on strawberries. 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 strawberries in Florida. This regulation establishes a 
    maximum permissible level for residues of Azoxystrobin 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 July 30, 2000.
    
    DATES: This regulation is effective January 29, 1999. Objections and 
    requests for hearings must be received by EPA on or before March 30, 
    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 
    combined residues or residues of the fungicide azoxystrobin and its Z 
    isomer, in or on strawberry at 0.05 part per million (ppm). This 
    tolerance will expire and is revoked on July 30, 2000. 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 safety standard and new 
    procedures. These activities are described below and discussed in 
    greater detail in the final rule establishing the time-limited 
    tolerance associated with 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 Azoxystrobin on Strawberry and FFDCA 
    Tolerances
    
        The Florida Department of Agriculture and Consumer Services 
    requested an emergency exemption on September 28, 1998 for the control 
    of anthracnose on strawberries. Anthracnose adversely affect the plants 
    in a variety of ways. It can cause plant losses (crown rot, root rot, 
    anthracnose of the stolon and petiole, but rot, and leaf spots) and 
    fruit losses (anthracnose fruit rot and flower blight).
        The two factors that have brought about this emergency condition 
    include variety shift and lack of efficacy of previously effective 
    fungicides. No single variety has all the desirable characteristics. 
    Among these desirable characteristics important to Florida growers are: 
    season-long production, early and late production, disease resistance, 
    insect and mite resistance, etc.
        EPA has authorized under FIFRA section 18 the use of azoxystrobin 
    on strawberry for control of anthracnose in Florida. 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 azoxystrobin in or on 
    strawberry. 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 July 30, 2000, 
    under FFDCA section 408(l)(5), residues of the pesticide not in excess 
    of the amounts specified in the tolerance remaining in or on 
    strawberries 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 azoxystrobin meets EPA's 
    registration requirements for use on strawberry 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 azoxystrobin 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 Florida 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 
    azoxystrobin, 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
    
    [[Page 4574]]
    
    scientific data and other relevant information in support of this 
    action EPA has sufficient data to assess the hazards of azoxystrobin 
    and to make a determination on aggregate exposure, consistent with 
    section 408(b)(2), for a time-limited tolerance for combined residues 
    or residues of azoxystrobin on strawberry at 0.05 ppm. EPA's assessment 
    of the dietary exposures and risks associated with establishing the 
    tolerance follows.
    
    A. Toxicological Profile
    
        EPA has evaluated the available toxicity data and considered its 
    validity, completeness, and reliability as well as the relationship of 
    the results of the studies to human risk. EPA has also considered 
    available information concerning the variability of the sensitivities 
    of major identifiable subgroups of consumers, including infants and 
    children. The nature of the toxic effects caused by azoxystrobin are 
    discussed below.
        1. Acute toxicity. The Agency evaluated the existing toxicology 
    database for azoxystrobin and did not identify an acute dietary 
    endpoint. Therefore, a risk assessment is not required.
        2. Short - and intermediate - term toxicity. The Agency evaluated 
    the existing toxicology database for short- and intermediate-term 
    dermal and inhalation exposure and determined that this risk assessment 
    is not required.
        3. Chronic toxicity. EPA has established the reference dose (RfD) 
    for azoxystrobin at 0.18 milligrams/kilogram/day (mg/kg/day). This RfD 
    is based on a chronic toxicity study in rats with a no observed 
    adversed effect level (NOAEL) of 18.2 mg/kg/day. Reduced body weights 
    and bile duct lesions were observed at the lowest effect level (LEL) of 
    34 mg/kg/day. An Uncertainty Factor (UF) of 100 was used to account for 
    both the interspecies extrapolation and the intraspecies variability.
        4. Carcinogenicity. The Agency determined that azoxystrobin should 
    be classified as ``Not Likely'' to be a human carcinogen according to 
    the proposed revised Cancer Guidelines. This classification is based on 
    the lack of evidence of carcinogenicity in long-term rat and mouse 
    feeding studies.
    
    B. Exposures and Risks
    
        1. From food and feed uses. Permanent tolerances have been 
    established (40 CFR 180.507(a)) for the combined residues of 
    azoxystrobin and its Z isomer, in or on a variety of raw agricultural 
    commodities at levels ranging from 0.01 ppm in pecans to 1.0 ppm in 
    grapes. In addition, time-limited tolerances have been established (40 
    CFR 180.507(b) at levels ranging from 0.006 ppm in milk to 20 ppm in 
    rice hulls) in conjunction with previous section 18 requests. Risk 
    assessments were conducted by EPA to assess dietary exposures and risks 
    from azoxystrobin 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 one day or single exposure. The Agency did not conduct an acute 
    risk assessment because no toxicological endpoint of concern was 
    identified during review of available data.
        ii. Chronic exposure and risk. In conducting this chronic dietary 
    risk assessment, EPA has made very conservative assumptions -- 100% of 
    strawberry commodities and all other commodities having azoxystrobin 
    tolerances will contain azoxystrobin residues and those residues would 
    be at the level of the tolerance with the exception of grapes-raisins, 
    grape-juice, tomatoes-juice, and tomatoes-puree -- which result in an 
    overestimation of human dietary exposure. Thus, in making a safety 
    determination for this tolerance, The Agency is taking into account 
    this conservative exposure assessment.
        The existing azoxystrobin tolerances (published, pending, and 
    including the necessary section 18 tolerance(s)) result in a 
    Theoretical Maximum Residue Contribution (TMRC) that is equivalent to 
    the following percentages of the RfD:

        3. From non-dietary exposure. Azoxystrobin is not currently 
    registered for any residential uses.
        4. Cumulative exposure to substances with common mechanism of 
    toxicity. Section 408(b)(2)(D)(v) requires that, when considering 
    whether to establish, modify, or revoke a tolerance, the Agency 
    consider ``available information'' concerning the cumulative effects of 
    a particular pesticide's residues and ``other substances that have a 
    common mechanism of toxicity.''
        EPA does not have, at this time, available data to determine 
    whether Azoxystrobin has a common mechanism of toxicity with other 
    substances or how to include this pesticide in a cumulative risk 
    assessment. Unlike other pesticides for which EPA has followed a 
    cumulative risk approach based on a common mechanism of toxicity, 
    Azoxystrobin 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 Azoxystrobin has a common mechanism of 
    toxicity with other substances. For more information regarding EPA's 
    efforts to determine which chemicals have a common mechanism of 
    toxicity and to evaluate the cumulative effects of such chemicals, see 
    the Final Rule for Bifenthrin Pesticide Tolerances (62 FR 62961, 
    November 26, 1997).
    
    C. Aggregate Risks and Determination of Safety for U.S. Population
    
        1. Acute risk. This is not applicable since no toxicological end-
    point of concern was identified during review of the available data.
        2. Chronic risk.Using the conservative TMRC exposure assumptions 
    described above, and taking into account the completeness and 
    reliability of the toxicity data, EPA has estimated the exposure to 
    azoxystrobin from food will utilize 3.8% of the RfD for the U.S. 
    population. EPA generally has no concern for exposures below 100% 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 
    azoxystrobin in drinking water, EPA does not expect the aggregate 
    exposure to exceed 100% of the RfD. Under current EPA guidelines, the 
    registered non-dietary uses of azoxystrobin do not constitute a chronic 
    exposure scenario. EPA concludes that there is a reasonable certainty 
    that no harm will result from chronic aggregate exposure to 
    azoxystrobin residues. EPA concludes that there is a reasonable 
    certainty that no harm will result from aggregate exposure to 
    azoxystrobin residues.
        3. Short- and intermediate-term risk. Short- and intermediate-term 
    aggregate exposure takes into account chronic dietary food and water 
    (considered to be a background exposure level) plus indoor and outdoor 
    residential exposure. This risk assessment is not applicable since no 
    indoor and outdoor residential exposure uses are currently registered 
    for azoxystrobin.
        4. Aggregate cancer risk for U.S. population. The Agency determined 
    that azoxystrobin should be classified as ``Not Likely'' to be a human 
    carcinogen according to the proposed revised Cancer Guidelines. The 
    Agency has therefore not conducted a cancer risk assessment.
        5. Determination of safety. Based on these risk assessments, EPA 
    concludes that there is a reasonable certainty that no harm will result 
    from aggregate exposure to Azoxystrobin residues.
    
    D. Aggregate Risks and Determination of Safety for Infants and Children
    
        1. Safety factor for infants and children --i. In general. In 
    assessing the potential for additional sensitivity of infants and 
    children to residues of Azoxystrobin, EPA considered data from 
    developmental toxicity studies in the rat and rabbit and a two-
    generation reproduction study in the rat. The developmental toxicity 
    studies are designed to evaluate adverse effects on the developing 
    organism resulting from maternal pesticide exposure during gestation. 
    Reproduction studies provide information relating to effects from 
    exposure to the pesticide on the reproductive capability of mating 
    animals and data on systemic toxicity.
        FFDCA section 408 provides that EPA shall apply an additional 
    tenfold margin of safety for infants and children in the case of 
    threshold effects to account for pre-and post-natal toxicity and the 
    completeness of the database unless EPA determines that a different 
    margin of safety will be safe for infants and children. Margins of 
    safety are incorporated into EPA risk assessments either directly 
    through use of a margin of exposure (MOE) analysis or through using 
    uncertainty (safety) factors in calculating a dose level that poses no 
    appreciable risk to humans. EPA believes that reliable data support 
    using the standard MOE and uncertainty factor (usually 100 for combined 
    inter- and intra-species variability)) and not the additional tenfold 
    MOE/uncertainty factor when EPA has a complete data base under existing 
    guidelines and when the severity of the effect in infants or children 
    or the potency or unusual toxic properties of a compound do not raise 
    concerns regarding the adequacy of the standard MOE/safety factor.
        ii. Developmental toxicity studies. -- a. Rabbit - In the 
    developmental toxicity study in rabbits, developmental NOAEL was 500 
    mg/kg/day, at the highest dose tested (HDT). Because there were no 
    treatment-related effects, the developmental LEL was  500 
    mg/kg/day. The maternal NOAEL was 150 mg/kg/day. The maternal LEL of 
    500 mg/kg/day was based on decreased body weight gain during dosing.
        b. Rat - In the developmental toxicity study in rats, the maternal 
    (systemic) NOAEL was not established. The maternal LEL of 25 mg/kg/day 
    at the lowest dose tested (LDT) was based on increased salivation. The 
    developmental (fetal) NOAEL was 100 mg/kg/day (HDT).
        iii. Reproductive toxicity study -- Rat - In the reproductive 
    toxicity study in rats, the parental (systemic) NOAEL was 32.3 mg/kg/
    day. The parental LEL of 165.4 mg/kg/day was based on decreased body 
    weights in males and females, decreased food consumption and increased 
    adjusted liver weights in females, and cholangitis. The reproductive 
    NOAEL was 32.3 mg/kg/day. The reproductive LEL of 165.4 mg/kg/day was 
    based on increased weanling liver weights and decreased body weights 
    for pups of both generations.
        iv. Pre- and post-natal sensitivity. The pre- and post-natal 
    toxicology data base for azoxystrobin is complete with respect to 
    current toxicological data requirements.
        v. Conclusion. The results of these studies indicate that infants 
    and children are not more sensitive to exposure, based on the results 
    of the rat and rabbit developmental toxicity studies and the 2-
    generation reproductive toxicity study in rats. The additional 10X 
    safety factor to account for sensitivity of infants and children was 
    removed by the Agency.
        2. Acute risk. Not applicable, no end-point.
        3. Chronic risk. Using the conservative exposure assumptions 
    described above, EPA has concluded that aggregate exposure to 
    azoxystrobin from food will utilize 1.9% to 5.6% of
    
    [[Page 4576]]
    
    the RfD for infants and children. EPA generally has no concern for 
    exposures below 100% 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 azoxystrobin in drinking water and from non-dietary, non-
    occupational exposure, 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 to infants and children from 
    aggregate exposure to azoxystrobin residues.
        4. Short- or intermediate-term risk. Not applicable, no end-point.
        5. Determination of safety. Based on these risk assessments, EPA 
    concludes that there is a reasonable certainty that no harm will result 
    to infants and children from aggregate exposure to azoxystrobin 
    residues.
    
    IV. Other Considerations
    
    A. Metabolism In Plants and Animals
    
        1. The nature of the residue in grapes is adequately understood. 
    These data are being translated for strawberries for this section 18 
    temporary tolerance.
        2. The qualitative nature of the residue in animals is adequately 
    understood for the purposes of this section 18 request. A ruminant 
    metabolism study has been submitted, however the animal metabolism data 
    have not been reviewed by the Office of Pesticide Program's Metabolism 
    Assessment Review Committee. The residues of concern in ruminants 
    appears to be different from that of plants. Unidentified metabolite 
    compounds,designated metabolites 2, 20, and 28, appear to be the major 
    components of the residue inruminant tissues. For the purposes of these 
    time-limited tolerances for emergencyexemptions only, the residues of 
    concern in animal tissues are azoxystrobin and its Z-isomer.
        3. As strawberry commodities are not considered to be major poultry 
    feed items, the natureand the magnitude of residues in poultry and eggs 
    are not of concern for the this section18.
    
    B. Analytical Enforcement Methodology
    
        Adequate enforcement methodology (example - gas chromotography) is 
    available to enforce the tolerance expression. The method may be 
    requested from: Calvin Furlow, PRRIB, IRSD (7502C), Office of Pesticide 
    Programs, Environmental Protection Agency, 401 M St., SW., Washington, 
    DC 20460. Office location and telephone number: Rm 101FF, CM #2, 1921 
    Jefferson Davis Hwy., Arlington, VA 22202, (703) 305-5229.
    
    V. Conclusion
    
        Therefore, the tolerance is established for combined residues or 
    residues of azoxystrobin in strawberry at 0.05 ppm.
    
    VI. Objections and Hearing Requests
    
        The new FFDCA section 408(g) provides essentially the same process 
    for persons to ``object'' to a tolerance regulation as was provided in 
    the old section 408 and in section 409. However, the period for filing 
    objections is 60 days, rather than 30 days. EPA currently has 
    procedural regulations which govern the submission of objections and 
    hearing requests. These regulations will require some modification to 
    reflect the new law. However, until those modifications can be made, 
    EPA will continue to use those procedural regulations with appropriate 
    adjustments to reflect the new law.
        Any person may, by March 30, 1999, file written objections to any 
    aspect of this regulation and may also request a hearing on those 
    objections. Objections and hearing requests must be filed with the 
    Hearing Clerk, at the address given above (40 CFR 178.20). A copy of 
    the objections and/or hearing requests filed with the Hearing Clerk 
    should be submitted to the OPP docket for this rulemaking. The 
    objections submitted must specify the provisions of the regulation 
    deemed objectionable and the grounds for the objections (40 CFR 
    178.25). Each objection must be accompanied by the fee prescribed by 40 
    CFR 180.33(i). If a hearing is requested, the objections must include a 
    statement of the factual issues on which a hearing is requested, the 
    requestor's contentions on such issues, and a summary of any evidence 
    relied upon by the requestor (40 CFR 178.27). A request for a hearing 
    will be granted if the Administrator determines that the material 
    submitted shows the following: There is genuine and substantial issue 
    of fact; there is a reasonable possibility that available evidence 
    identified by the requestor would, if established, resolve one or more 
    of such issues in favor of the requestor, taking into account 
    uncontested claims or facts to the contrary; and resolution of the 
    factual issues in the manner sought by the requestor would be adequate 
    to justify the action requested (40 CFR 178.32). 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.
    
    VII. Public Record and Electronic Submissions
    
        EPA has established a record for this rulemaking under docket 
    control number [OPP-300772] (including any comments and data submitted 
    electronically). A public version of this record, including printed, 
    paper versions of electronic comments, which does not include any 
    information claimed as CBI, is available for inspection from 8:30 a.m. 
    to 4 p.m., Monday through Friday, excluding legal holidays. The public 
    record is located in Room 119 of the Public Information and Records 
    Integrity Branch, Information Resources and Services Division (7502C) 
    Office of Pesticide Programs, Environmental Protection Agency, CM #2, 
    1921 Jefferson Davis Highway, Arlington, VA.
        Electronic comments may be sent directly to EPA at:
        opp-docket@epamail.epa.gov.
    
    
        Electronic comments must be submitted as an ASCII file avoiding the 
    use of special characters and any form of encryption.
        The official record for this rulemaking, as well as the public 
    version, as described above will be kept in paper form. Accordingly, 
    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 which 
    will also include all comments submitted directly in writing. The 
    official rulemaking record is the paper record maintained at the 
    Virginia address in ``ADDRESSES'' at the beginning of this document.
    
    VIII. Regulatory Assessment Requirements
    
    A. Certain Acts and Executive Orders
    
        This final rule establishes a tolerance/exemption from the 
    tolerance requirement 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
    
    [[Page 4577]]
    
    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/exemption 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 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).
