    Zinc phosphide; Pesticide Tolerances for Emergency Exemptions
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: This regulation establishes a time-limited tolerance for 
    residues of phosphine in or on potatoes, sugar beet (roots), and sugar 
    beet (tops). 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 
    potatoes and sugarbeets. This regulation establishes a maximum 
    permissible level for residues of phosphine in these food commodities 
    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 
    tolerances will expire and are revoked on May 1, 2000.
    
    DATES: This regulation is effective December 9, 1998. Objections and 
    requests for hearings must be received by EPA on or before February 8, 
    1999.

    SUPPLEMENTARY INFORMATION: EPA, on its own initiative, pursuant to 
    sections 408(e) and (l)(6) of the FFDCA, 21 U.S.C. 346a(e) and (l)(6), 
    is establishing tolerances for residues of the rodenticide zinc 
    phosphide, in or on potatoes and sugar beets at 0.05 part per million 
    (ppm). These tolerances will expire and are revoked on May 1, 2000. EPA 
    will publish a document in the Federal Register to remove the revoked 
    tolerances 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 Zinc Phosphide on Potatoes and Sugar 
    beets and FFDCA Tolerances
    
        Potato and sugar beet growers in Idaho have experienced substantial 
    losses in recent years due to vole and mouse damage. The only 
    registered option available to sugar beet and potato growers in Idaho 
    is to use zinc phosphide on non-crop land surrounding their fields. 
    Where fields are surrounded by other crops or bare ground, there are no 
    registered controls or other effective non-chemical methods. EPA has 
    authorized under FIFRA section 18 the use of zinc phosphide on potatoes 
    and sugar beets for control of voles and mice in Idaho. 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 phosphine in or on 
    potatoes and sugar beets. 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 May 1, 
    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 
    potatoes and sugar beets 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
    
    [[Page 67796]]
    
    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 zinc phosphide meets EPA's 
    registration requirements for use on potatoes and sugar beets or 
    whether permanent tolerances for this use would be appropriate. Under 
    these circumstances, EPA does not believe that these tolerances serve 
    as a basis for registration of zinc phosphide 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 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 
    zinc phosphide, 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 phosphine 
    and to make a determination on aggregate exposure, consistent with 
    section 408(b)(2), for a time-limited tolerance for residues of zinc 
    phosphide on potatoes and sugar beet (roots) at 0.05 ppm and sugar beet 
    (tops) at 0.1 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 zinc phosphide are 
    discussed below.
        1. Acute toxicity. No toxicology studies were identified by EPA 
    which demonstrated the need for an acute dietary risk assessment.
        2. Short - and intermediate - term non-dietary toxicity. Based on 
    the acute dermal LD50 study in rabbits, no appropriate toxic 
    effects were identified for risk assessment. In that study no 
    mortalities were observed at 5,000 milligram/kilogram mg/kg. At the 
    lowest observed effect level (LOEL) of 2,000 mg/kg, there was a 
    decrease in body weight. Based on the physical properties of the 
    chemical, dermal absorption is expected to be very low, since zinc 
    phosphide reacts with water and stomach acid to produce the toxic gas 
    phosphine from oral, but not dermal, exposure. As no endpoint of 
    toxicological concern for dermal exposure has been identified, no 
    dermal penetration data were required. The requirement for an acute 
    inhalation study has been waived, thus zinc phosphide has been placed 
    in Toxicity Category I for acute inhalation exposure.
        3. Chronic toxicity. EPA has established the RfD for zinc phosphide 
    at 0.001 (mg/kg/day). However, as indicated in the Reregistration 
    Eligibility Document (RED), a chronic dietary risk assessment is not 
    required because exposure from food sources is expected to be minimal 
    to non-existent. There are no detectable residues in potatoes. 
    Furthermore potatoes are often washed and cooked before they are eaten 
    thereby further reducing any trace of residues. Residue studies showed 
    there were detectable residues in sugar beet roots and tops; however, 
    these commodities are not direct human foods and no dietary consumption 
    is expected. Sugar beet tops are fed to livestock; however, there is no 
    likelihood of residues of zinc phosphide being found through transfer 
    of residues to meat and milk. Residues of zinc phosphide ingested by 
    livestock would be immediately converted to phosphine and metabolized 
    to naturally occurring phosphorus compounds. Furthermore, the Agency 
    believes that the refining process for sugar beets will remove any 
    unreacted zinc phosphide from refined sugar and the data requirements 
    for a sugar beet processing study has been waived. Therefore the Agency 
    has determined that there is no likelihood of residues of zinc 
    phosphide occurring in any processed commodities and no chronic dietary 
    exposure assessment is required.
        4. Carcinogenicity. Zinc phosphide has not been classified as to 
    its carcinogenic potential since cancer studies have been waived. 
    Although this chemical has food uses, dietary exposure is expected to 
    be minimal.
    
    B. Exposures and Risks
    
        1. From food and feed uses. Tolerances have been established (40 
    CFR 180.284) for the residues of zinc phosphide, in or on a variety of 
    raw agricultural commodities. Risk assessments were conducted by EPA to 
    assess dietary exposures and risks from zinc phosphide 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. Acute dietary endpoints were not 
    identified; thus an acute dietary risk assessment was not performed.
        ii. Chronic exposure and risk. For the purpose of assessing chronic 
    dietary exposure to zinc phosphide from food, EPA assumed tolerance 
    level residues and 100% of crop treated for potatoes, sugarbeets and 
    all other commodities having zinc phosphide tolerances. These 
    conservative assumptions result in over estimation of human dietary 
    exposures.
        2. From drinking water. The EPA Safe Drinking Water Hotline has 
    indicated (06/97) that there are no established maximum contaminant 
    levels (MCL) for residues of zinc phosphide in drinking water. No 
    health advisory levels for zinc phosphide in drinking water have been 
    established. There is no entry for zinc phosphide in the ``Pesticides 
    in Groundwater Database'' (EPA 734-12-92-001, September 1992). 
    Furthermore as indicated in the RED, zinc phosphide and its degradation 
    products appear to have a low potential for ground water or surface 
    water contamination. Therefore, dietary exposure is not expected from 
    either ground or surface water fed drinking water and a drinking water 
    risk assessment was not performed in the RED. Since the issuance of the 
    RED, drinking water levels of comparison (DWLOCs) for zinc phosphide 
    were calculated in accordance with the current Standard Operating 
    Procedures for Drinking Water Exposure and Risk Assessments. The Agency 
    concludes with reasonable certainty that exposure to zinc phosphide in 
    drinking water would not result in unacceptable levels of concern.
        i. Acute exposure and risk. Acute dietary endpoints have not been 
    identified; therefore, a DWLOC for acute dietary exposure was not 
    determined.
        ii. Chronic exposure and risk. Zinc phosphide degrades rapidly to 
    Zn2+ and PH3, which sorb strongly to soil and are 
    common nutrients in soil. Zinc
    
    [[Page 67797]]
    
    phosphide and its degradation products appear to have a low potential 
    for ground water or surface water contamination. Therefore, EPA 
    concludes with reasonable certainty that the residues of zinc phosphide 
    in drinking water would not result in unacceptable levels of concern.
        3. From non-dietary exposure. Zinc phosphide is currently 
    registered for use on the following residential non-food sites: hand-
    applied bait to underground burrows in/on the following sites/settings: 
    bulb crops, golf course turfgrass, lawns, ornamentals, nurseries, 
    parks, homes, industrial, commercial, and agricultural buildings. 
    Because of these residential uses, EPA has concerns about possible 
    post-application exposures to children. A post-application exposure and 
    risk assessment, using the method described in the draft Standard 
    Operating Procedures (SOPs) for Residential Exposure Assessments was 
    conducted. The margin of exposure (MOE) of 310 for post-application 
    exposure to children at residential sites does not exceed EPA's level 
    of concern (i.e., acceptable MOEs are 100). The dose 
    estimates generated here are based on some central tendency (i.e., body 
    weight) and some upper-percentile assumptions (i.e., ingestion rate of 
    dry pesticide formulation, and maximum application rate) and are 
    considered to be representative of high-end exposure. The uncertainties 
    associated with this assessment stem from the use of an assumed 
    ingestion rate of dry pesticide formulation. The dose estimates are 
    considered to be reasonable high-end estimates based on professional 
    judgement.
        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.''
        Although zinc phosphide may share a common mode of toxicity (the 
    generation of phosphine gas) with other chemicals (aluminum and 
    magnesium phosphide), the Agency has determined that any future 
    cumulative risk determination involvling these chemicals will not 
    include the current uses of zinc phosphide. This determination is based 
    on the fact that exposures to phosphine from zinc phosphide in food or 
    water are negligible due to zinc phosphide's rapid degradation and 
    limited use patterns.
    
    C. Aggregate Risks and Determination of Safety for U.S. Population
    
        1. Acute risk. Acute dietary endpoints were not identified; thus an 
    acute dietary risk assessment was not performed.
        2. Chronic risk. A chronic dietary reference dose (RfD) was 
    established for zinc phosphide at 0.0001 mg/kg/day (see Zinc Phosphide 
    RED, 7/98). However, as indicated in the RED, a chronic dietary risk 
    assessment is not required because exposure from food sources is 
    expected to be minimal to non-existent. There are no detectable 
    residues in potatoes. Furthermore potatoes are often washed and cooked 
    before they are eaten thereby further reducing any trace of residues. 
    Residue studies showed there were detectable residues in sugar beet 
    (roots) and (tops); however, these commodities are not direct human 
    foods and no dietary consumption is expected. Sugar beet (tops) are 
    feed to livestock; however, there is no likelihood of residues of zinc 
    phosphide being found through transfer of residues to meat and milk. 
    Residues of zinc phosphide ingested by livestock would be immediately 
    converted to phosphine and metabolized to naturally occurring 
    phosphorus compounds. Furthermore, the Agency believes that the 
    refining process or sugar beets will remove any unreacted zinc 
    phosphide from refined sugar and the data requirements for a sugar beet 
    processing study has been waived. Therefore the Agency has determined 
    that there is no likelihood of residue of zinc phosphide occurring in 
    any processed commodities and no chronic dietary exposure assessment is 
    required.
        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. A short and intermediate term aggregate risk 
    assessment is not required as a non-dietary endpoint was not 
    identified.
        4. Determination of safety. Based on these risk assessments, EPA 
    concludes that there is a reasonable certainty that no harm will result 
    from aggregate exposure to zinc phosphide 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 zinc phosphide, EPA considered data from 
    developmental toxicity studies 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 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 100-
    fold factor (usually 100 for combined inter- and intra-species 
    variability) and not the additional tenfold safety 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. In the developmental study in 
    rats, the maternal no observed adverse effect level (NOAEL) was 2.0 mg/
    kg/day, based on increased mortality at the LOEL of 4.0 mg/kg/day. The 
    developmental (fetal) NOAEL was 4.0 mg/kg/day, the highest dose tested.
        iii. Pre- and post-natal sensitivity. The toxicological data base 
    for evaluating pre- and post-natal toxicity for zinc phosphide is not 
    complete. EPA is not requiring these studies because exposure from food 
    sources is expected to be insignificant. The rat developmental toxicity 
    data provided no indication of increased sensitivity of fetal rats to 
    in utero exposure to zinc phosphide. In that study, no developmental 
    effects were observed at the highest dose tested which was shown to be 
    maternally toxic. An additional uncertainty factor of 10 was applied to 
    the reference dose calculation to account for the extrapolation from 
    subchronic to chronic exposure, the lack of reproductive toxicity data, 
    and the lack of chronic toxicity data in a non-rodent species, this 
    additional uncertainty factor will accomodate the inability to assess 
    the potential for increased sensitivity of infants and children, 
    because of the lack of animal data.
    
    [[Page 67798]]
    
        2. Determination of safety. Based on these risk assessments, EPA 
    concludes that there is a reasonable certainty that no harm will result 
    to infants and children from aggregate exposure to zinc phosphide 
    residues.
    
    IV. Other Considerations
    
    A. Metabolism In Plants and Animals
    
        The residue of concern is zinc phosphide per se, measured as 
    phosphine. There is no expectation of secondary residues in meat, milk, 
    poultry, and eggs as a result of the registered zinc phosphide uses .
    
    B. Analytical Enforcement Methodology
    
        Adequate analytical methodology (spectrophotometric) is available 
    in PAM II (Sec. 180.284, Method A) to enforce the tolerance expression. 
    The method determines zinc phosphide residues as phosphine gas.
    
    C. Magnitude of Residues
    
        Residues of phosphine resulting from the proposed use of zinc 
    phosphide are not expected to exceed 0.05 ppm in potatoes, 0.05 ppm in 
    sugar beet (roots), and 0.1 ppm in sugar beet (tops). Concentration of 
    residues in potato and sugar beet processing by-products is not 
    expected. There is no reasonable expectation of secondary residues in 
    meat, milk, poultry, or eggs.
    
    D. International Residue Limits
    
        No Codex, Canadian or Mexican Maximum Residue Levels have been 
    established for zinc phosphide.
    
    V. Conclusion
    
        Therefore, the tolerances are established for residues of zinc 
    phosphide in potatoes and sugar beet (roots) at 0.05 ppm and sugar beet 
    (tops) at 0.1 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 issued by EPA under 
    new section 408(e) and (l)(6) 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 February 8, 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-300760] (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, Crystal 
    Mall #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 tolerances 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 prior consultation as 
    specified by Executive Order 12875, entitled Enhancing the 
    Intergovernmental Partnership (58 FR 58093, October 28, 1993), or 
    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 tolerances 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
    
    [[Page 67799]]
    
    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).
