    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Clean Air Act directs EPA to promulgate regulations 
    specifying those provisions of the Act for which it is appropriate to 
    treat Indian Tribes in the same manner as States. For those provisions 
    specified, a Tribe may develop and implement one or more of its own air 
    quality programs under the Act. This proposed rule sets forth the CAA 
    provisions for which it is appropriate to treat Indian Tribes in the 
    same manner as States, establishes the requirements that Indian Tribes 
    must meet if they choose to seek such treatment, and provides for 
    awards of Federal financial assistance to Tribes. EPA requests public 
    comments on all aspects of today's proposal.
    
    DATES: Comments on this proposed rule must be received on or before 
    November 23, 1994.
    
    ADDRESSES: Comments must be mailed (in duplicate, if possible) to the 
    EPA Air Docket Office (6102), Attn: Air Docket No. A-93-3087, room

    I. Background of the Proposed Rule
    
    A. Development of the Proposed Rule
    
        This notice describes proposed regulatory changes to implement 
    section 301(d) of the Clean Air Act, as amended, 42 U.S.C. 7401, et 
    seq. (the ``Act'' or ``CAA''). Section 301(d) requires EPA to 
    promulgate regulations that provide for Indian Tribes, if they so 
    choose, to assume responsibility for the development and implementation 
    of CAA programs on lands within the exterior boundaries of their 
    reservations or other areas within their jurisdiction. This Tribal 
    authority will apply to all CAA programs which the EPA Administrator 
    determines to be appropriate in taking final action on this proposal. 
    An Indian Tribe that takes responsibility for a CAA program under this 
    rule would essentially be treated in the same way as a State would be 
    treated for that program, with any exceptions noted in this rule and 
    discussed below in this preamble.
    1. Federal/EPA Indian Policy
        In developing this proposed rule, EPA has acted on the principles 
    expressed in existing Federal policy statements regarding Indian 
    Tribes. On January 24, 1983, the President issued a Federal Indian 
    Policy stressing two related themes: (1) that the Federal government 
    will pursue the principle of Indian ``self-government'' and (2) that it 
    will work directly with Tribal governments on a ``government-to-
    government'' basis. Presidential support was reaffirmed in an April 1, 
    1993 statement.
        On November 8, 1984, in response to the 1983 Federal statement, EPA 
    adopted a policy statement and implementing guidance addressing the 
    administration of EPA environmental programs on Indian reservations. 
    EPA's policy is ``to give special consideration to Tribal interests in 
    making Agency policy, and to ensure the close involvement of Tribal 
    Governments in making decisions and managing environmental programs 
    affecting reservation lands.'' EPA committed to pursue certain 
    principles to meet this objective, including the following:
    
        EPA recognizes Tribal Governments as sovereign entities with 
    primary authority and responsibility for the reservation populace. 
    Accordingly, EPA will work directly with Tribal Governments as the 
    independent authority for reservation affairs, and not as political 
    subdivisions of States or other governmental units.
    * * * * *
        In keeping with the principle of Indian self-government, the 
    Agency will view Tribal Governments as the appropriate non-Federal 
    parties for making decisions and carrying out program 
    responsibilities affecting Indian reservations, their environments, 
    and the health and welfare of the reservation populace. Just as 
    EPA's deliberations and activities have traditionally involved the 
    interests and/or participation of State Governments, EPA will look 
    directly to Tribal Governments to play this lead role for matters 
    affecting reservation environments.
    
    See November 8, 1984 ``EPA Policy for the Administration of 
    Environmental Programs on Indian Reservations'' at p. 2. EPA 
    Administrator Carol M. Browner reaffirmed the 1984 policy in a 
    Memorandum issued on March 14, 1994.
    2. Consultation With Tribal Representatives
        In addition, EPA has consulted with Tribal representatives in 
    developing this proposed rule. EPA discussed preliminary issues 
    associated with the proposed rule at the ``First National Tribal 
    Conference on Environmental Management'' held in Cherokee, North 
    Carolina in May 1992 and the ``Second National Tribal Conference on 
    Environmental Management'' in Cherokee held in May 1994.
        In the Fall of 1992, EPA met with Tribal representatives at three 
    outreach meetings in Chicago, Denver and San Francisco. These meetings 
    included a discussion of issues raised by this proposed rule as well as 
    EPA's efforts to assist Tribes in obtaining training in air quality 
    management. Overall, representatives of approximately 70 different 
    Tribes attended. In September 1993, EPA discussed a draft of this 
    proposed rule with representatives of approximately 40 Tribes at a 
    seminar sponsored by EPA and the Office of Native American Programs at 
    Northern Arizona University and a subsequent meeting with 
    representatives of State and local governments sponsored by the State 
    and Territorial Air Pollution Program Administrators/Association of 
    Local Air Pollution Control Officials. EPA has also consulted with 
    Tribal and State representatives periodically throughout the 
    development of the proposed rule.
        EPA received comments both during and following the Tribal and 
    State outreach meetings. EPA has considered these comments in 
    developing today's proposed rule. To the extent any such commenters 
    have concerns that have not been adequately addressed by today's 
    proposal, they should submit formal written comments to EPA in response 
    to today's action. Any such comments must be received by the deadline 
    indicated at the outset of today's notice and submitted to the EPA 
    address specified above.
    
    B. General Structure of the CAA
    
        In order to fully understand this proposal, a basic understanding 
    of the structure of the CAA and its division of responsibilities 
    between EPA and the States is necessary. Such a description is set 
    forth below. In addition, a brief description of some of the many 
    programs contained in the CAA is set forth in Addendum A, as an 
    introduction and guidance to Tribes wishing to develop their own CAA 
    programs. Reading Addendum A in conjunction with today's proposed 
    action will also facilitate the reader's understanding of the 
    discussion that follows.
        The CAA is implemented in two basic ways. The principal method is 
    through a cooperative partnership between the States and EPA. While 
    this partnership can take several shapes, generally EPA issues national 
    standards or Federal requirements and the States assume primary 
    responsibility for implementing these requirements. However, as a 
    prerequisite to assuming implementation responsibility, States must 
    submit their programs to EPA and must demonstrate that their programs 
    meet minimum Federal CAA requirements. Among these requirements is the 
    mandate that States demonstrate that they have adequate legal authority 
    and resources to implement the programs.
        If a State program is approved or if the authority to implement a 
    Federal program is delegated to a State, EPA maintains an ongoing 
    oversight role to ensure that the program is adequately enforced and 
    implemented and to provide technical and policy assistance. An 
    important aspect of EPA's oversight role is that EPA retains legal 
    authority to bring an enforcement action against a source violating a 
    CAA program implemented by the States. Thus, if a State fails to 
    adequately enforce CAA requirements, EPA can step in and ensure that 
    they are followed.
        An example of this cooperative Federal/State arrangement is 
    provided by Title V of the Act, 42 U.S.C. 7661-7661e, which contains 
    requirements for an operating permit program. Generally, the program 
    requires that certain sources of air pollution obtain permits which 
    contain all of the requirements under the Act applicable to such 
    sources. EPA has issued rules specifying the minimum requirements for 
    State permit programs. 57 FR 32250 (July 21, 1992). States are required 
    to develop programs consistent with minimum Federal requirements and to 
    submit those programs to EPA for approval. In those instances when 
    State programs are approved by EPA, the approved States will be 
    primarily responsible for implementing these provisions of the CAA. EPA 
    will maintain an active oversight role to provide necessary assistance 
    and to ensure that the EPA-approved State programs continue to be 
    implemented consistent with minimum Federal requirements.
        In the second, less common form of CAA implementation, EPA is 
    primarily responsible both for setting standards or interpreting the 
    requirements of the Act and for implementing the Federal requirements 
    that are established. Under this approach, the Act provides little 
    formal role for States.1 In general, this approach is reserved for 
    programs requiring a high degree of uniformity in their implementation.
    ---------------------------------------------------------------------------
    
        \1\ States nevertheless often actively participate in federal 
    rulemakings and policy development even if the CAA does not call for 
    primary implementation by the States. EPA similarly encourages 
    Tribes to participate actively in EPA's rulemakings and policy 
    development.
    ---------------------------------------------------------------------------
    
        Title VI of the Act, which provides for the phase-out of certain 
    substances that deplete stratospheric ozone, is one such program, since 
    it affects products sold throughout interstate commerce. 42 U.S.C. 
    7671-7671q. Title VI is both a Federally established and Federally 
    managed program. EPA is charged with issuing the rules to implement the 
    phase-out. Through, for example, reporting requirements and 
    enforcement, EPA also ensures that the restrictions in production and 
    consumption of ozone-depleting substances that are called for by the 
    Act are, in fact, met.
        Section 301(d)(2) of the Act authorizes EPA to issue regulations 
    specifying those provisions of the Act ``for which it is appropriate to 
    treat Indian tribes as States.'' 42 U.S.C. section 7601(d)(2). Thus, 
    the CAA programs where States have a formal implementation role will be 
    the programs that are directly affected by today's proposed action. 
    Conversely, those programs that are established and implemented 
    primarily by EPA will largely be unaffected by today's proposal.
    
    C. Description of Section 301(d) of the CAA
    
        Section 301(d)(1) of the CAA authorizes EPA to ``treat Indian 
    tribes as States'' under the Act, so that Tribes may develop and 
    implement CAA programs in the same manner as States within Tribal 
    reservations or in other areas subject to Tribal jurisdiction.2 
    For a Tribe to be eligible for such treatment it must be Federally 
    recognized (see section 302(r)) and must meet the three criteria set 
    forth in section 301(d)(2)(A)-(C). Briefly, these criteria consist of: 
    (1) a showing of an adequate governing body; (2) that is capable of 
    implementing the particular requirements of the CAA and applicable 
    regulations for which the Tribe is seeking program approval; and (3) 
    within the exterior boundaries of the reservation or other areas within 
    the Tribe's jurisdiction. The precise criteria are set forth in today's 
    proposed rule and are described in detail in Part III.A. below, 
    together with EPA's proposal as to how this eligibility determination 
    should be made.
    ---------------------------------------------------------------------------
    
        \2\ For convenience of expression, portions of this rule refer 
    only to Tribal programs within reservations. However, these 
    references should not be interpreted to limit Tribal programs solely 
    to lands within reservation boundaries since the CAA acknowledges 
    that tribes may possess authority over off-reservation lands.'' See 
    Part II.A, below.
    ---------------------------------------------------------------------------
    
        At the same time, the Act recognizes that it may not be appropriate 
    or feasible in all instances to treat Tribes and States identically. 
    Accordingly, EPA is required under section 301(d)(2) of the Act to 
    promulgate regulations ``specifying those provisions of [the CAA] for 
    which it is appropriate to treat Indian tribes as States.'' Tribes that 
    satisfy the criteria discussed above are eligible to implement those 
    provisions specified by EPA if the minimum Federal requirements set out 
    in the provisions have been met. In general, EPA is proposing that 
    Tribes be eligible to implement the same provisions as States, with 
    some exceptions, as set forth in today's proposed rule and discussed in 
    Part III.B. below.
        In addition, section 301(d)(3) of the Act gives EPA the discretion 
    to promulgate regulations establishing the elements of Tribal 
    implementation plans (``TIPs'') and procedures for approval or 
    disapproval of those plans or portions thereof. See Addendum A, ``Title 
    I'' discussion. These regulations would be implemented in conjunction 
    with section 110(o) of the Act, which provides that any TIP that is 
    submitted to EPA under section 301(d) shall be reviewed in accordance 
    with the provisions for review of State implementation plans (``SIPs'') 
    set out in section 110, except as otherwise provided by this 
    regulation. Once effective, the TIP would be applicable to all areas 
    located within the exterior boundaries of the reservation. See section 
    110(o). In today's action, EPA is proposing TIP regulations and 
    procedures, as well as procedures for the review of other Tribal air 
    programs (``TAPs''). These procedures are discussed further in Part 
    III.C. below.
        Finally, section 301(d) of the Act makes provision for EPA to 
    furnish grant and contract assistance to Tribes. See section 301(d)(1), 
    (5) of the CAA. The grant provisions proposed today are described in 
    Part IV of this preamble.
    
    II. Jurisdictional Issues
    
    A. Delegation or Grant of CAA Authority to Tribes
    
        It is a settled point of law that Congress may, by statute, 
    expressly delegate Federal authority to a Tribe. United States v. 
    Mazurie, 419 U.S. 544, 554 (1975). See also South Dakota v. Bourland, 
    113 S. Ct. 2309, 2319-20 (1993); Brendale v. Confederated Tribes and 
    Bands of the Yakima Indian Nation, 492 U.S. 408, 426-28 (1989) (White, 
    J., for four Justice plurality). Such a delegation or grant of 
    authority can provide a Federal statutory source of Tribal authority 
    over designated areas, whether or not the Tribe's inherent authority 
    would extend to all such areas. It is EPA's proposed interpretation of 
    the CAA that the Act grants, to Tribes approved by EPA to administer 
    CAA programs in the same manner as States, authority over all air 
    resources within the exterior boundaries of a reservation for such 
    programs. This grant of authority by Congress would enable such Tribes 
    to address conduct on all lands, including non-Indian owned fee lands, 
    within the exterior boundaries of a reservation. Thus, this proposed 
    interpretation relates to the potential scope of regulatory 
    jurisdiction that may be exercised by eligible Tribes under EPA-
    approved Tribal Clean Air Act programs (hereafter ``approved'' 
    Tribes).3
    ---------------------------------------------------------------------------
    
        \3\ As indicated in Part III.B.4, in some instances qualifying 
    Tribes may have a role in CAA implementation without having to make 
    an entire program submittal.
    ---------------------------------------------------------------------------
    
        The Agency recognizes that a Tribe will generally have inherent 
    sovereign authority over air resources within the exterior boundaries 
    of its reservation. As stated in Mazurie, the sovereign authority of 
    Indian Tribes extends ``over both their members and their territory.'' 
    419 U.S. at 557. Thus, Tribes generally have extensive authority to 
    regulate activities on lands that are held by the United States in 
    trust for the Tribe. See Montana v. United States, 450 U.S. 544, 557 
    (1981). Furthermore, a Tribe ``may * * * retain inherent power to 
    exercise civil authority over the conduct of non-Indians on fee lands 
    within its reservation when that conduct threatens or has some direct 
    effect on the * * * health or welfare of the tribe.'' Montana, 450 U.S. 
    at 566. However, a Tribe's inherent authority must be determined on a 
    case-by-case basis, considering whether the conduct being regulated has 
    a direct effect on the health or welfare of the Tribe substantial 
    enough to support the Tribe's jurisdiction over non-Indians. See 
    Brendale, 492 U.S. 408; see also 56 FR 64876 at 64877-64879 (Dec. 12, 
    1991).4 Such a determination is not necessary with a direct grant 
    of statutory authority.5
    ---------------------------------------------------------------------------
    
        \4\ In proposing to interpret the CAA as granting approved 
    Tribes authority over all air resources within the exterior 
    boundaries of a reservation, EPA recognizes that its approach under 
    some of the other statutes it administers relies on a Tribe's 
    inherent authority.
        \5\ Even without this proposed direct grant of authority, Indian 
    Tribes would very likely have inherent authority over all activities 
    within reservation boundaries that are subject to CAA regulation. 
    The high mobility of air pollutants, resulting area-wide effects, 
    and the seriousness of such impacts, would all tend to support 
    Tribal inherent authority; as noted below, these factors also 
    underscore the desirability of cohesive air quality management of 
    all air pollution sources within reservation boundaries including 
    those air pollution-related activities on fee lands within 
    reservation boundaries. See, e.g., Bourland, 113 S. Ct. at 2320 
    (reaffirming the Montana ``exceptions to `the general proposition 
    that the inherent sovereign powers of an Indian tribe do not extend 
    to the activities of nonmembers of the tribe''') (citation omitted) 
    (1993); see also, e.g., CAA section 101(a)(2), 42 U.S.C. section 
    7401(a)(2); H.R. Rep. No. 490, 101st Cong., 2d Sess. (1990); S. Rep. 
    No. 228, 101st Cong., 1st Sess. (1989).
    ---------------------------------------------------------------------------
    
        EPA's proposed position that the CAA constitutes a statutory grant 
    of jurisdictional authority to Tribes is consistent with the language 
    of the Act, which authorizes EPA to treat a Tribe as a State for the 
    regulation of ``air resources within the exterior boundaries of the 
    reservation or other areas within the tribe's jurisdiction.''6 
    Section 301(d)(2)(B) (emphasis added). EPA believes that this statutory 
    provision, viewed within the overall framework of the CAA, reflects a 
    territorial view of Tribal jurisdiction and authorizes a Tribal role 
    for all air resources within the exterior boundaries of Indian 
    reservations without distinguishing among various categories of on-
    reservation land. EPA believes a territorial approach to air quality 
    regulation best advances rational, sound air quality management. Air 
    pollutants disperse over areas several and sometimes even hundreds of 
    miles from their source of origin, as dictated by the physical and 
    chemical properties of the pollutants at issue and the prevailing winds 
    and other meteorological conditions. The high mobility of air 
    pollutants, resulting areawide effects and the seriousness of such 
    impacts, underscores the undesirability of fragmented air quality 
    management within reservations.
    ---------------------------------------------------------------------------
    
        \6\ As indicated above, EPA interprets the second clause of this 
    provision as meaning that Tribes may also assert jurisdiction over 
    air resources that are not within the boundaries of their 
    reservations. However, EPA has not interpreted this clause as a 
    direct grant of jurisdictional authority to Tribes with respect to 
    such off-reservation air resources. Rather, where a Tribe submits a 
    program asserting jurisdiction over air resources outside the 
    boundaries of a reservation, EPA will require a demonstration of the 
    factual and legal basis for the Tribe's inherent authority over such 
    resources, consistent with relevant principles of Federal Indian 
    law.
    ---------------------------------------------------------------------------
    
        Moreover, language contained in two other provisions of the CAA, 
    which expressly recognizes Tribal authority over all areas within the 
    exterior boundaries of the reservation provides particularly compelling 
    evidence that Congress intended to adopt this territorial approach. One 
    such provision is in the CAA program governing the amount of 
    incremental air quality deterioration allowed in ``clean air'' areas. 
    Section 164(c) of the CAA provides that ``[l]ands within the exterior 
    boundaries of reservations of federally recognized Indian Tribes may be 
    redesignated [with regard to the prevention of significant 
    deterioration of air quality] only by the appropriate Indian governing 
    body.''
        In addition, section 110(o) of the CAA provides that upon approval 
    by EPA, Tribal Implementation Plans (TIPs) ``shall become applicable to 
    all areas * * * located within the exterior boundaries of the 
    reservation, notwithstanding the issuance of any patent and including 
    rights-of-way running through the reservation.'' Section 110(o) of the 
    Act recognizes that approved Tribes will exercise authority over all 
    areas within the exterior boundaries of a reservation for purposes of 
    TIPs. TIPs, in turn, are the administrative tools for implementing the 
    requirements under Title I of the CAA necessary to assure attainment 
    and maintenance of the national ambient air quality standards (NAAQS), 
    one of the central CAA programs. Significant regulatory entanglement 
    and inefficiencies could result if Tribes have jurisdiction over such 
    plans pursuant to section 110(o) of the Act, but are not found to have 
    jurisdiction within reservation boundaries over non-TIP CAA programs. 
    For example, a stationary source located on an area of a reservation 
    over which the Tribe was found to lack inherent authority would be 
    subject to the Tribal Implementation Plan provisions imposing NAAQS-
    related requirements, but might be determined to be subject to State 
    regulation for some other CAA program. This entanglement could 
    potentially subject a source to differing local regulatory authorities, 
    possibly with conflicting goals and approaches, and potentially 
    duplicative or inconsistent reporting, monitoring and other regulatory 
    requirements. There is no evidence that Congress intended to create 
    such complex jurisdictional entanglements. These entanglements are 
    reasonably avoided by interpreting the CAA as granting to approved 
    Tribes regulatory authority over all air resources within a 
    reservation.
         Further, a grant of authority to Tribes for NAAQS-related purposes 
    alone would conflict with the implementation of the operating permit 
    program called for by Title V of the Act. Title V explicitly prohibits 
    partial State permit programs unless, at a minimum, such a program 
    ``ensures compliance with * * * [a]ll requirements of [Title] I * * * 
    applicable to sources required to have a permit.'' Section 502(f) 
    (emphasis added); see also section 502(b)(5)(A) (requires permitting 
    authorities ``to have adequate authority to * * * assure compliance by 
    sources required to have a permit under this title with each applicable 
    standard, regulation, or requirement under this Act'') (emphasis added) 
    and section 504(a) (each permit issued under Title V ``shall include * 
    * * conditions as are necessary to assure compliance with the 
    applicable requirements of this [Act], including the requirements of 
    the applicable implementation plan''). Since States could not 
    unilaterally ``ensure compliance with * * * [a]ll requirements of 
    [Title] I'' within Indian reservations because Tribes are granted 
    authority over implementation plans under section 110(o), it appears 
    that States could not, in fact, submit Title V permit programs for 
    Indian reservations that would conform with section 502(f) or other 
    provisions of Title V.
        A basic rule of statutory construction is to avoid interpreting a 
    statute in a manner that would nullify or render meaningless a 
    statutory provision.7 Because section 110(o) confers on approved 
    Tribes the authority to administer Title I programs on Indian 
    reservations, the provision of Title V requiring that a permit program 
    must at a minimum ensure compliance with the applicable requirements of 
    Title I cannot be met by States seeking authority to implement a Title 
    V program within the boundaries of a reservation. These provisions can 
    reasonably be harmonized by construing the Act as generally granting 
    approved Tribes CAA regulatory authority over all air resources within 
    the exterior boundaries of their reservations. Thus, this statutory 
    structure further supports EPA's proposed interpretation of the CAA as 
    granting approved Tribes authority within reservation boundaries.
    ---------------------------------------------------------------------------
    
        \7\See U.S. v. Nordic Village, Inc., 112 S.Ct. 1011, 1015 (1992) 
    (rejecting an interpretation that ``violates the settled rule that a 
    statute must, if possible, be construed in a fashion that every word 
    has some operative effect'') (citation omitted); Boise Cascade Corp. 
    v. U.S. EPA, 942 F.2d 1427, 1432 (9th Cir. 1992) (``[u]nder accepted 
    canons of statutory interpretation, we must interpret statutes as a 
    whole, giving effect to each word and making every effort not to 
    interpret a provision in a manner that renders other provisions of 
    the same statute inconsistent, meaningless or superfluous'') 
    (citations omitted).
    ---------------------------------------------------------------------------
    
        Accordingly, in light of the statutory language and the overall 
    statutory scheme8, EPA proposes to exercise the rulemaking 
    authority entrusted to it by Congress to conclude that the CAA grants 
    approved Tribes authority over all air resources within the exterior 
    boundaries of a reservation. See generally Chevron U.S.A., Inc. v. 
    NRDC, 467 U.S. 837, 842-45 (1984).9
    ---------------------------------------------------------------------------
    
        \8\This proposed interpretation of the CAA as generally 
    delegating jurisdictional authority to approved Tribes is also 
    supported by the legislative history, which provides some additional 
    evidence of Congressional attention to this issue: ``the Act 
    constitutes an express delegation of power to Indian tribes to 
    administer and enforce the Clean Air Act in Indian lands'' (citation 
    to Brendale omitted). S. Rep. No. 228, 101st Cong., 1st Sess. 79 
    (1989).
        \9\Further, it is a well-established principle of statutory 
    construction that statutes should be construed liberally in favor of 
    Indians, with ambiguous provisions interpreted in ways that benefit 
    tribes. See County of Yakima v. Confederated Tribes and Bands of the 
    Yakima Indian Nation, 112 S.Ct. 683, 693 (1992). In addition, 
    statutes should be interpreted so as to comport with tribal 
    sovereignty and the federal policy of encouraging tribal 
    independence. See Ramah Navajo School Board, Inc. v. Bureau of 
    Revenue of New Mexico, 458 U.S. 832, 846 (1982).
    ---------------------------------------------------------------------------
    
        Based on recent Supreme Court case law, EPA has construed the term 
    ``reservation'' to incorporate trust land that has been validly set 
    apart for use by a Tribe, even though that land has not been formally 
    designated as a ``reservation.'' See 56 FR at 64,881 (Dec. 12, 1991); 
    see also Oklahoma Tax Commission v. Citizen Band Potawatomi Indian 
    Tribe of Oklahoma, 111 S.Ct. 905, 910 (1991). EPA will be guided by 
    relevant case law in interpreting the scope of ``reservation'' under 
    the CAA.
        Section 301(d)(2)(B) of the CAA also provides that a Tribe may be 
    treated in the same manner as a State for functions regarding air 
    resources ``within the exterior boundaries of the reservation or other 
    areas within the tribe's jurisdiction'' (emphasis added). The 
    emphasized language envisions potential Tribal jurisdiction under the 
    CAA over areas that lie outside the exterior boundaries of a 
    reservation, upon a fact-based showing of a Tribe's inherent authority 
    over sources located on such lands. Thus, this provision authorizes an 
    eligible Tribe to develop and implement Tribal air quality programs on 
    off-reservation lands that are determined to be within the Tribe's 
    inherent jurisdiction. Accordingly, for purposes of this rule, EPA 
    proposes to conclude that an eligible Tribe may be able to implement 
    its air quality programs on off-reservation lands up to the limits of 
    ``Indian country,'' as defined in 18 U.S.C. section 1151, provided the 
    Tribe can adequately demonstrate authority to regulate air quality on 
    the off-reservation lands in question under general principles of 
    Indian law.
        In sum, EPA is proposing to interpret the CAA as granting approved 
    Tribes regulatory authority over all air resources within the exterior 
    boundaries of their reservations. Thus, no independent fact-based 
    showing of inherent Tribal jurisdiction will be required for air 
    resources located within such reservation boundaries. EPA recognizes 
    that ``other'' off-reservation areas may fall within Tribal 
    jurisdiction. EPA is proposing to interpret the CAA as providing no 
    blanket grant of Federal authority for such areas. Thus, for off-
    reservation areas, a Tribe must demonstrate that it has inherent 
    authority over sources it seeks to regulate under general principles of 
    Indian law.
    
    B. Federal Authority and Protection of Tribal Air Resources
    
        The CAA authorizes EPA to protect air quality throughout Indian 
    country. EPA intends to use this authority to remedy and prevent gaps 
    in CAA protection for Tribal air resources. EPA's authority to provide 
    this CAA protection is based in part on the general purpose of the Act, 
    which is national in scope. As stated in section 101(b)(1) of the Act, 
    Congress intended to ``protect and enhance the quality of the Nation's 
    air resources so as to promote the public health and welfare and the 
    productive capacity of its population'' (emphasis added). It seems 
    clear that Congress intended for the CAA to be a ``general statute 
    applying to all persons to include Indians and their property 
    interests.'' Phillips Petroleum Co. v. United States E.P.A., 803 F.2d 
    545, 556 (10th Cir. 1986) (holding that the Safe Drinking Water Act 
    applied to Indian Tribes and lands by virtue of being a nationally 
    applicable statute; see generally id. at 553-58).
        Section 301(a) of the Act delegates to EPA broad authority to issue 
    such regulations as are necessary to carry out the functions of the 
    Act. Further, several provisions of the Act call for Federal issuance 
    of a program where, for example, a State fails to adopt a program, 
    adopts an inadequate program or fails to adequately implement a 
    required program. E.g., sections 110(c) and 502 (d), (e), (i) of the 
    Act. It follows that Congress intended that EPA would similarly have 
    broad legal authority in instances when Tribes choose not to develop a 
    program, fail to adopt an adequate program or fail to adequately 
    implement an air program authorized under section 301(d). In addition, 
    section 301(d)(4) of the CAA empowers the Administrator to directly 
    administer CAA requirements so as to achieve the appropriate purpose, 
    where Tribal implementation of CAA requirements is inappropriate or 
    administratively infeasible. These provisions evince Congressional 
    intent to authorize EPA to directly implement CAA programs where Tribes 
    fail to submit approvable programs or lack authority to do so.
        In fact, EPA is currently providing Federal support for CAA 
    protection within reservations. For example, EPA administers the permit 
    program governing review of proposed new and modified major stationary 
    sources of air pollution (``new source review'' or ``NSR'') on 
    Reservations and other areas in Indian country (hereafter ``Tribal 
    lands''). There are several reasons for this emphasis in the exercise 
    of EPA's authority.
        Many Tribal lands have air quality that presently meets the 
    national ambient air quality standards (``NAAQS''), and the central 
    concern is to prevent the relatively clean air from significantly 
    deteriorating. Thus, EPA has ensured that major sources seeking to 
    locate on Tribal lands obtain the Prevention of Significant 
    Deterioration (``PSD'') permit required under the CAA's NSR program. In 
    broad overview, this program imposes limitations on the ambient air 
    quality impact of new or modified major stationary sources and requires 
    the application of best available control technology on such sources. 
    See section 165 of the Act. Similarly, in those circumstances where the 
    air quality on Tribal lands currently is worse than the NAAQS, EPA's 
    administration of the nonattainment NSR program prevents the air 
    quality from further deteriorating by ensuring that a proposed major 
    source implements the most stringent control technology (the ``lowest 
    achievable emission rate'' as defined in section 171(3)) and offsets 
    its emissions by obtaining emissions reductions from nearby sources. 
    Section 173 of the Act.
        Owners and operators that construct air pollution sources on Tribal 
    lands without first obtaining the proper permit from EPA expose 
    themselves to Federal enforcement action and citizen suits. For 
    example, section 165 of the Act, 42 U.S.C. 7475, prohibits the 
    construction of a major emitting facility that does not have a PSD 
    permit. Section 173, 42 U.S.C. 7503, contains a similar requirement for 
    new and modified major stationary sources in nonattainment areas. 
    Sections 113 and 167, 42 U.S.C. 7413 & 7467, authorize EPA to take 
    enforcement action (including, in certain instances, criminal action) 
    against an owner or operator that is in violation of the requirement to 
    obtain a preconstruction permit that meets the requirements of the Act. 
    Furthermore, section 304 of the Act, 42 U.S.C. 7604, authorizes any 
    person to bring a ``citizen suit'' in U.S. district court against an 
    owner or operator who constructs any new or modified major stationary 
    source without a PSD permit or nonattainment NSR permit that meets the 
    Act's requirements.
        EPA also currently provides technical and financial support to 
    Tribes that have initiated the process of developing Tribal air 
    programs. For example, some EPA Regional Offices are currently 
    providing such assistance to Tribes that have air quality that is worse 
    than the NAAQS. The objective is to assist the Tribes in developing a 
    strategy for controlling emissions from existing sources that will 
    bring the area back into attainment with the NAAQS. Because EPA has not 
    finalized today's rule authorizing Tribes to submit Federal CAA 
    programs to EPA for approval, some EPA Regions are now working with 
    Tribes to develop programs that will be promulgated and administered by 
    EPA until this rule is finalized and a Tribal program is 
    approved.10 Where air quality problems have already been 
    identified, it is EPA's policy to proceed expeditiously, in conjunction 
    with Tribes, to address such problems.
    ---------------------------------------------------------------------------
    
        \1\0Such an interim EPA-administered program would be displaced 
    upon EPA's approval of a Tribal program addressing the same CAA 
    requirements.
    ---------------------------------------------------------------------------
    
        In addition, as described in Part I.B, there are some programs that 
    are solely Federal programs (e.g. Phase I of the Acid Rain Program and 
    Title VI of the Act, which provides for the phase-out of certain 
    substances that deplete stratospheric ozone). Such programs apply to 
    sources located on Tribal lands in the same manner as sources on lands 
    subject to State jurisdiction.
        EPA views these efforts as an important and substantial first step 
    in providing CAA protection of reservation air resources.
        EPA also intends to develop an implementation strategy for 
    achieving Federal CAA protection of air resources within Indian 
    reservations. The strategy will be designed to prioritize EPA resources 
    in support of this rule. It is EPA's policy to assist Tribes in 
    developing comprehensive and effective air quality management programs 
    to insure that Tribal air quality management programs will be 
    implemented to the extent necessary on Indian reservations. EPA will do 
    this by, among other things, providing technical advice and assistance 
    to Indian Tribes on air quality issues. EPA intends to consult with 
    Tribes to identify their particular needs for air program development 
    assistance and to provide on-going assistance as necessary.
        However, as it required many years to develop State and Federal 
    programs to cover lands subject to State jurisdiction, so it will 
    require time to develop Tribal and Federal programs to cover 
    reservations and other lands subject to Tribal jurisdiction. As a first 
    step in this process, EPA intends to draft a Plan for Reservation Air 
    Program Implementation that will provide a strategy for developing 
    reservation programs in accordance with this policy. The Plan will 
    identify priority needs and include a strategy to address them by 
    providing technical and grant assistance for the development of air 
    quality management programs. EPA will seek appropriate input from 
    Tribal governments in developing the Plan.
    
    C. Objective of Tribal Primacy and Self-Determination
    
        Ultimately, of course, EPA would prefer to work with Tribes to have 
    the Tribes develop and administer their own air quality management 
    programs under the CAA, just as EPA works with States. This is the 
    principal objective of the Federal financial assistance described in 
    Part IV below.
        While some Tribes may entirely develop their own CAA programs, 
    other Tribes may consider forming Tribal consortia. Smaller Tribes in 
    particular may wish to form consortia or create inter-Tribal agencies 
    as ways to develop the necessary expertise to administer CAA programs 
    in a cost-effective way. One of the advantages of forming a consortium 
    of Tribes is that a Tribe may rely on the expertise and resources of 
    the consortium in demonstrating that the Tribe is reasonably expected 
    to be capable of carrying out the functions to be exercised, as 
    described below.
        Today's action also does not require Tribes to develop CAA programs 
    wholly from scratch. For example, a Tribe may adopt or incorporate 
    standards from an adjacent or similarly situated State, with 
    appropriate revisions that would adapt the State standards to 
    reservation conditions and Tribal policies. The use of such adaptations 
    would enable Tribes to build on State experience and expertise, and 
    might represent quicker and less costly ways to establish Tribal 
    programs than developing Tribal programs independently. This technique 
    of utilizing small-scaled adaptations of State programs would allow 
    Tribes to build experience and expertise that could later be used to 
    revise existing programs, if appropriate.
        Tribes could also choose to negotiate a cooperative agreement with 
    an adjoining State to jointly plan and administer CAA programs that are 
    appropriately tailored to individual reservation conditions and Tribal 
    policies. Such an agreement would be subject to the review and approval 
    of the Administrator or her delegatee, if it is to be made part of an 
    approvable Tribal air program under the CAA.
        Aside from any formal arrangements between Tribes and States, EPA 
    notes that the objective of this rule, and EPA's responsibility in 
    overseeing the administration of the CAA, is to provide air quality 
    protection. Therefore, EPA encourages all affected sovereigns to work 
    cooperatively in informal capacities to protect the public health and 
    welfare from the serious health and welfare effects associated with air 
    pollution.
    
    III. Tribal CAA Programs
    
        The discussion which follows addresses streamlined procedures that 
    EPA is proposing to satisfy the eligibility requirements set out in 
    section 301(d)(2) of the Act. These are proposed requirements that 
    Tribes must meet in order to obtain approval to implement CAA programs. 
    The discussion also identifies those provisions of the Act for which 
    EPA is proposing to treat Indian Tribes in the same manner as States 
    and those provisions for which EPA believes such treatment is 
    infeasible or otherwise inappropriate.
        One of EPA's central concerns is to encourage Tribes to develop and 
    administer Clean Air Act programs on Tribal lands in the same way that 
    States currently do on State lands. This concern is grounded in the 
    objective of Tribal self-government as enunciated in both the Federal 
    and the EPA Indian Policies. In order to facilitate this process, EPA 
    is proposing to eliminate duplicative review and unnecessary delay 
    during EPA's processing of Tribal program submittals. The eligibility 
    determination process proposed in today's action is consistent with an 
    EPA policy pronouncement that followed from EPA's review of the Tribal 
    programs it administers under other environmental statutes. Further, 
    EPA is proposing to accept ``reasonably severable'' Tribal air program 
    submittals that meet the applicable requirements of the CAA. This will 
    allow Tribes to identify and then immediately target their most 
    important air quality issues without the corresponding burden of 
    developing entire CAA programs. Further, it allows Tribes to develop 
    incremental expertise that will facilitate development and expansion of 
    further programs over time.
    
    A. New Process for Determining Eligibility for CAA Programs
    
        To be eligible to be treated in the same manner as a State for CAA 
    programs, including financial assistance, an applicant must meet the 
    definition of ``tribe'' in section 302(r) of the Act (i.e. it must be 
    Federally recognized) and must satisfy the three criteria set forth in 
    section 301(d)(2)(A)-(C) of the Act. These criteria are set out in 
    today's proposed rule and concern the Tribe's governing body, its 
    jurisdiction, and its capability to carry out the necessary functions 
    under the Act.
        In general these same criteria are set forth under the Clean Water 
    Act and the Safe Drinking Water Act. EPA has previously issued 
    regulations implementing the criteria under those Acts. These 
    regulations have come to be known as the ``treatment as a state'' 
    (``TAS'') process.11 Approval under this process was required 
    every time a Tribe sought to obtain an EPA grant or implement an EPA 
    program on its reservation.
    ---------------------------------------------------------------------------
    
        \1\1EPA recognizes that Tribes are sovereign nations with a 
    unique legal status and a relationship to the Federal government 
    that is significantly different from that of States. EPA believes 
    that Congress did not intend to alter this when it authorized 
    treatment of Tribes ``as States'' under the CAA. Rather, Congress 
    intends to ensure that, to the extent appropriate and feasible, 
    Tribes may assume a role in implementing the CAA on Tribal lands 
    that is comparable to the role States have in implementing the CAA 
    on State lands.
    ---------------------------------------------------------------------------
    
        Because the ``TAS'' process proved to be quite burdensome to 
    Tribes, EPA formed a working group to focus on ways of improving and 
    simplifying the process. After considering the workgroup's 
    recommendations, EPA announced a policy that is intended to streamline 
    and simplify the process. Memorandum from F. Henry Habicht, the Deputy 
    Administrator of EPA, to the Agency, dated November 10, 1992. EPA is 
    proposing to implement this new policy in this rulemaking, and is 
    calling the resulting new process the ``eligibility'' process. See also 
    56 FR 1380 (March 23, 1994) (proposing similar revision to Tribal 
    approval process in Clean Water Act and Safe Drinking Water Act 
    regulations).
        Under the new eligibility process proposed in today's action, a 
    Tribe does not need to go through a separate eligibility review every 
    time it seeks approval for grant funding or to implement a specific 
    program. Instead, a Tribe's eligibility may be determined at the same 
    time that it seeks approval for a particular program. By making the 
    eligibility determination a part of the program approval process, much 
    of the delay and duplication inherent in the old sequential TAS process 
    should be reduced, if not eliminated. In addition, EPA is proposing to 
    simplify some of the demonstrations of eligibility that will be 
    required under the Clean Air Act, as discussed below. Finally, after 
    promulgation of this rule, EPA intends to facilitate development of 
    Tribal applications by providing Tribes with a narrative checklist of 
    the eligibility requirements described below.
    1. Federally Recognized Tribe
        A Tribe is defined in section 302(r) of the Act as follows:
    
    [A]ny Indian tribe, band, nation, or other organized group or 
    community, including any Alaska Native village, which is Federally 
    recognized as eligible for the special programs and services 
    provided by the United States to Indians because of their status as 
    Indians.
    
    The requirement of Federal recognition is common to all statutes 
    authorizing EPA to treat Tribes in a manner similar to that in which it 
    treats States. Any Tribe that has been approved for ``TAS'' under any 
    of the existing Water Act regulations or any other EPA program is 
    Federally recognized. Moreover, once a Tribe has been found to be 
    Federally recognized in the course of approval under any EPA-
    administered statute, or any provision of the CAA, it need only so 
    state in the future. To facilitate review of Tribal applications, EPA 
    therefore requests that Tribal applications inform EPA whether the 
    Tribe has been approved for ``TAS'' under the old process or deemed 
    eligible to receive funding or authorization for any EPA-administered 
    environmental program under the revised process governing treatment of 
    Tribes in the same manner as States.
        Any other Tribe need only state that it appears on the list of 
    Federally recognized Tribes that the Secretary of the Interior 
    periodically publishes in the Federal Register. See 58 FR 54364 (Oct. 
    21, 1993). If the Tribe notifies EPA that it has been recognized but is 
    not included on this list because the list has not been updated, EPA 
    will verify the fact of recognition with the Department of the Interior 
    (``DOI'').
    2. Substantial Governmental Duties and Powers
        A Tribe also must show that it ``has a governing body carrying out 
    substantial governmental duties and powers.'' This requirement is also 
    found in the Federal Water Pollution Control Act (``Clean Water Act'') 
    and the Public Health Service Act (``Safe Drinking Water Act''). See 33 
    U.S.C. 1377(e) & 42 U.S.C. section 300j-11(b). Accordingly, as 
    discussed above, a Tribe that has had a submittal approved by EPA under 
    either of these provisions has already established that it meets the 
    governmental requirement and need not make this showing again. 
    Similarly, a Tribe that has made this showing in the course of 
    obtaining approval for a Clean Air Act program need not do so again. In 
    either case, a Tribe may simply state that it has already been 
    approved.
        A Tribe that has not yet made its initial showing of ``substantial 
    governmental duties and powers'' can do so by demonstrating that it has 
    a governing body that is presently carrying out substantial 
    governmental functions. A Tribe will be able to make the required 
    demonstration if it is currently performing governmental functions to 
    promote the public health, safety, and welfare of its population within 
    a defined area. Many Indian Tribal governments perform these functions. 
    Examples of such functions include, but are not limited to, levying 
    taxes, acquiring land by exercising the power of eminent domain, and 
    police power. Such examples should be included in a narrative statement 
    supporting the certification, which describes: (1) The form of the 
    Tribal government, (2) the types of essential governmental functions 
    currently performed, such as those listed above; and (3) the legal 
    authorities for performing these functions (e.g. Tribal constitutions 
    or codes). It should be relatively easy for Tribes to meet this 
    requirement without submitting copies of specific documents unless 
    requested to do so by EPA.
    3. Jurisdiction Requirement
        As discussed in section II.A above, EPA is proposing to interpret 
    the CAA as granting or delegating certain Federal authority to approved 
    Tribes over all air resources within the exterior boundaries of their 
    reservations. Generally, therefore, the significant issue that remains 
    in determining the extent of Tribal jurisdiction is the precise 
    boundary of the reservation in question. Accordingly, a Tribal 
    jurisdictional showing must identify, with clarity and precision, the 
    exterior boundaries of the reservation. Consistent with the simplified 
    review process, EPA is not proposing to specify particular supporting 
    materials that the Tribe must provide. However, a Tribal submission 
    will need to contain information adequate to demonstrate to EPA the 
    location and limits of the reservation, which will usually include a 
    map and a legal description of the area. EPA will determine the meaning 
    of the term ``reservation'' as indicated previously.
        Note that there may be less frequent instances when more complex 
    legal and factual demonstrations must be made to establish 
    jurisdiction. As indicated above, section 301(d)(2)(B) of the Act 
    addresses jurisdiction over ``air resources within the exterior 
    boundaries of the reservation or other areas within the tribe's 
    jurisdiction'' (emphasis added). While EPA is proposing to construe the 
    Act as delegating to Tribes authority over all air resources within the 
    exterior boundaries of their reservations, the Agency will require a 
    Tribe to demonstrate its inherent authority over any areas outside of 
    the exterior boundaries of the reservation before EPA will approve a 
    Tribal program covering such areas. Where a Tribe seeks to develop and 
    administer an air program on off-reservation lands, the Tribal 
    submittal must be accompanied by appropriate legal and factual 
    information which supports its inherent authority to regulate emission 
    sources located on such lands.
        Under the TAS process which EPA has implemented in the past, EPA 
    would not determine that a Tribe had the requisite jurisdiction without 
    first notifying appropriate ``governmental entities,'' such as States, 
    other Tribes and Federal land management agencies, of the Tribe's 
    jurisdictional assertions. Those entities were then given an 
    opportunity to comment on the Tribe's jurisdictional statement, and 
    whenever a comment raised a ``competing or conflicting claim,'' EPA 
    could not approve the Tribal application without first consulting with 
    DOI. Consistent with the revised eligibility policy, EPA is proposing 
    to implement a more streamlined approach under the CAA.
        The first time a Tribe submits an application to EPA under the CAA, 
    EPA will, upon receipt of the application, notify all appropriate 
    ``governmental entities''\12\ regarding the Tribe's assertion of 
    jurisdiction. The precise content of EPA's notification of other 
    governmental entities will depend on the geographic extent of the 
    Tribe's jurisdictional assertion. Specifically, if a Tribe seeks only 
    to implement a CAA program within the exterior boundaries of its 
    reservation, EPA's notification of other governments will only specify 
    the geographic boundaries of the reservation, as set forth in the 
    Tribe's application. However, where a Tribe seeks to administer a CAA 
    program on lands outside the exterior boundaries of a reservation, EPA 
    will notify the appropriate governmental entities of the substance of 
    and bases for the Tribe's assertion of inherent jurisdiction with 
    respect to such off-reservation lands.
    ---------------------------------------------------------------------------
    
        \12\For purposes of the CAA rule, EPA is proposing to adopt the 
    same definition of ``governmental entities'' as the Agency did in 
    its December 1991 Water Quality Standards regulation. See 56 FR 
    64876 at 64884 (Dec. 12, 1991).
    ---------------------------------------------------------------------------
    
        The appropriate governmental entities will have fifteen days 
    following their receipt of EPA's notification to provide formal 
    comments to EPA regarding any dispute they might have with the Tribe 
    concerning the boundary of the reservation. Where a Tribe has asserted 
    jurisdiction over off-reservation lands, and has included a more 
    detailed jurisdictional statement in its application, appropriate 
    governmental entities may request a one-time fifteen day extension to 
    the general fifteen day comment period. In all cases, comments from 
    appropriate governmental entities must be offered in a timely manner, 
    and must be limited to the Tribe's jurisdictional assertion. Where no 
    timely comments are presented, EPA will conclude that there is no 
    objection to the Tribal applicant's identified reservation boundaries 
    (or, if relevant, its assertion of jurisdiction outside the 
    reservation). Further, to raise a competing or conflicting claim, a 
    commenter must clearly explain the substance, basis, and extent of its 
    objections. Finally, where EPA receives timely notification of a 
    dispute, it may obtain such additional information and documentation as 
    it believes appropriate and may, at its option, consult with DOI.
        Where EPA identifies a dispute and cannot confidently resolve it 
    promptly, it will retain the option of limiting approval of a Tribal 
    program to those areas that a Tribe has clearly shown are part of the 
    reservation (or are otherwise within the Tribe's jurisdiction). This 
    will allow EPA to approve the portion of a Tribal application that 
    covers all undisputed areas, while withholding action on the portion of 
    the application that addresses areas where a jurisdictional issue has 
    not been satisfactorily resolved. However, this approach will be 
    subject to any applicable statutory restrictions. See, e.g., section 
    110(k) of the Act (calls upon EPA to complete action on a SIP submittal 
    within certain specified timeframes).
        Once EPA has made a determination under the CAA or other EPA-
    administered environmental programs concerning the boundaries of a 
    reservation, it will rely on that determination in evaluating all 
    future applications from that Tribe under the CAA unless the 
    application presents different legal issues. For example, once the 
    Agency has arrived at a position concerning a reservation boundary 
    dispute, it will not alter that position in the absence of significant 
    new factual or legal information. Thus, as with the recognition and 
    governmental requirements, there will generally be no need to provide 
    EPA with additional demonstrations of jurisdiction, unless the Tribe is 
    making a more expansive jurisdictional assertion in a subsequent 
    submittal.
        EPA believes that this new process for resolving questions of 
    jurisdiction constitutes a significant improvement over the old TAS 
    jurisdiction process. It will provide States with an opportunity to 
    notify EPA of boundary disputes and enable EPA to obtain relevant 
    information as needed while minimizing delays in the process and 
    focusing its inquiry on what is likely to be the principal relevant 
    issue, namely, the geographic boundaries of the reservation.
    4. Capability Requirement
        Section 301(d)(2)(C) of the CAA provides that in determining Tribal 
    eligibility the Administrator also must determine that the Tribe ``is 
    reasonably expected to be capable * * * of carrying out the functions 
    to be exercised in a manner consistent with the terms and purposes of 
    [the CAA] and all applicable regulations.'' A program-by-program 
    inquiry into the question of capability is necessary since a Tribe may 
    have capability to carry out certain activities but not others. 
    Therefore, EPA may request that to establish capability a Tribe submit 
    a narrative statement or other documents showing it is capable of 
    administering the program for which it is seeking approval. The 
    specific capabilities which must be described are set forth in today's 
    proposed rule.
        In evaluating a Tribe's demonstration of capability, EPA may 
    consider the following factors:
        (1) The Tribe's previous management experience;
        (2) Existing environmental or public health programs administered 
    by the Tribe;
        (3) The mechanism(s) in place for carrying out the executive, 
    legislative, and judicial functions of the Tribal government;
        (4) The relationship between regulated entities and the 
    administrative agency of the Tribal government that will be the 
    regulator; and
        (5) The technical and administrative capabilities of the staff to 
    administer and manage the program.
        EPA recognizes that certain Tribes may not have substantial 
    experience administering environmental programs. A lack of experience 
    will not preclude a Tribe from demonstrating the required capability. 
    Otherwise Tribes would be placed in the dilemma of being denied the 
    opportunity to develop the requisite capability because they lack such 
    capability. For this reason, today's proposed rule requires Tribes 
    either to show that they have the necessary management and technical 
    skills or to submit a plan detailing steps for acquiring those skills.
        However, this flexibility does not change the requirement that to 
    obtain approval for a particular program under the CAA the Tribe must 
    submit a fully effective program that meets all the applicable 
    statutory and regulatory requirements associated with the program in 
    question. Because a Tribe may not want to go through the expense of 
    developing such a program without first being assured of meeting the 
    eligibility requirements, today's proposed rule provide that a Tribe 
    may, at its option, ask for a preliminary finding on any or all of 
    these requirements.
        EPA's evaluation of capability will also consider the relationship 
    between the existing or proposed Tribal agency that will implement the 
    program in question and any potential regulated Tribal entities. It is 
    not uncommon for a Tribe to be both the regulator and regulated entity, 
    and such a situation could result in a conflict of interest since the 
    Tribe would then be regulating itself. Independence of the regulator 
    and regulated entity best assures effective and fair administration of 
    a program.
        A Tribe will generally not be required to divest itself of 
    ownership of any regulated entities to address this problem. Instead, 
    for example, the Tribe could create an independent organization to 
    regulate Tribal entities subject to CAA regulatory requirements.13 
    Similar arrangements could be established using existing Tribal 
    organizations.
    ---------------------------------------------------------------------------
    
        \1\3While States also are both the regulator and regulated 
    entity, state government organization is typically one in which the 
    State agency operating the regulated entity is not the same State 
    agency that has primary regulatory authority. Thus, this separation 
    of functions helps avoid potential conflicts of interest.
    ---------------------------------------------------------------------------
    
        This discussion is intended to alert Tribes at an early date about 
    a potential bar to regulatory program assumption that must be resolved. 
    For example, section 110 of the CAA sets out some of the basic 
    requirements that SIPs must meet to assure attainment and maintenance 
    of the NAAQS. Section 110(a)(2)(E)(ii) of the Act directs that SIPs 
    must provide requirements that the State comply with the requirements 
    applicable to State boards under section 128. Section 128, in turn, 
    provides that each SIP shall contain requirements that:
    
        (1) Any board or body which approves permits or enforcement 
    orders under [the CAA] shall have at least a majority of members who 
    represent the public interest and do not derive any significant 
    portion of their income from persons subject to permits or 
    enforcement orders under [the CAA], and
        (2) Any potential conflicts of interest by members of such board 
    or body or the head of an executive agency with similar powers be 
    adequately disclosed.
    
        EPA does not intend to limit Tribal flexibility in creating 
    structures which will ensure adequate separation of the regulator and 
    regulated entity. Instead, EPA will evaluate whether the Tribal 
    submittal will ensure adequate separation of the regulator and 
    regulated entity on a case-by-case basis in the context of the 
    statutory and regulatory requirements applicable to the CAA program for 
    which a Tribe is seeking approval.
    5. Tribal consortia
        Each member of a Tribal consortium must meet the eligibility 
    qualifications described above. However, members of a consortium may 
    rely on the expertise and resources of the consortium in demonstrating 
    that the Tribe meets the capability requirement described above.
        For example, some members of a consortium may have more technical 
    expertise and environmental management experience than other members. A 
    Tribe with less resources and expertise may rely on the combined 
    resources of the consortium in demonstrating that the Tribe is 
    ``reasonably expected'' to be capable of carrying out the functions to 
    be exercised. However, a Tribe relying on a consortium in this manner 
    must provide reasonable assurances that the Tribe has responsibility 
    for carrying out necessary functions in the event the consortium fails 
    to.
    
    B. Provisions for Which Tribal Implementation is Appropriate
    
    1. Tribal Implementation is Generally Appropriate
        Part III.A discussed the eligibility requirements that a Tribe must 
    meet in order to be treated as a State under the Clean Air Act. There 
    is a separate question of whether it is appropriate to treat eligible 
    Tribes in the same manner as States for all provisions under the Act, 
    or whether only certain provisions lend themselves to such an approach. 
    The Act provides that the Administrator shall promulgate regulations:
    
    specifying those provisions of [the CAA] for which it is appropriate 
    to treat Indian tribes as States.
    
        Section 301(d)(2). The Act further provides,
    
        [i]n any case in which the Administrator determines that the 
    treatment of Indian tribes as identical to States is inappropriate 
    or administratively infeasible, the Administrator may provide, by 
    regulation, other means by which the Administrator will directly 
    administer such provisions so as to achieve the appropriate purpose.
    
        Section 301(d)(4). Thus, read together, the Act delegates to the 
    Administrator broad discretion in determining those provisions of the 
    Clean Air Act for which Tribes should be treated in the same manner as 
    States and those provisions for which such treatment would be 
    inappropriate or infeasible.
        It is EPA's basic position, proposed here, that treatment of Tribes 
    in the same manner as States is appropriate for all programs under the 
    Act with the exception of only a few provisions (those for which EPA 
    has determined that it is infeasible or otherwise inappropriate to 
    treat States and Tribes in the same manner). EPA proposes to be 
    inclusive in identifying the provisions of the Act for which it is 
    appropriate to treat Tribes in the same manner as States so as to 
    maximize the opportunities for Tribal participation in CAA programs.
        In light of this basic approach, today's proposed rule provides 
    that Tribes will generally be treated in the same manner as States for 
    all the provisions of the Clean Air Act, and specifies the limited 
    exceptions to this approach. EPA is proposing to treat Tribes in the 
    same manner as States for all of the remaining provisions of the 
    statute not identified as exceptions in the discussion below. Today's 
    action also addresses alternative means to achieve the intended purpose 
    of the Act, where EPA believes such provisions are necessary in light 
    of a proposed exception. Section 301(d)(4).
        A common concern raised by both Tribes and States during the 
    development of this proposed rule was the potential for sources located 
    on State or Tribal lands to adversely impact air quality on downwind 
    State or Tribal lands. EPA is proposing in this rule that the CAA 
    protections against interstate pollutant transport apply with equal 
    force to States and Tribes.
        Thus, for example, EPA is proposing that the prohibitions and 
    authority contained in sections 110(a)(2)(D) and 126 of the CAA apply 
    to Tribes in the same manner as States. Section 110(a)(2)(D), among 
    other things, requires States to include provisions in their SIPs that 
    prohibit emissions activity within the State from significantly 
    contributing to nonattainment, interfering with maintenance of the 
    NAAQS, or interfering with measures under the PSD or visibility 
    protection programs in another State. Section 126 authorizes any State 
    to petition EPA to enforce these prohibitions against a State 
    containing an allegedly offending source or group of sources.
    2. Exceptions to Tribal Implementation
        EPA notes at the outset that recurring provisions for which EPA is 
    proposing not to treat Tribes in the same manner as States involve 
    certain Clean Air Act submittal deadlines. The Act contains many 
    deadlines that mandate the submittal of a State plan, program or other 
    requirement by certain dates. However, Tribes are not similarly 
    compelled to develop and seek approval of air programs. Section 
    301(d)(2) provides for EPA to promulgate regulations specifying ``those 
    provisions of this [Act] for which it is appropriate to treat Indian 
    tribes as States'' but does not require Indian Tribes to develop CAA 
    programs.
        Further, the State program submittal deadlines in the statute are 
    based upon a relatively long history of Clean Air Act planning and 
    implementation by States.14 States have assumed an active role in 
    Clean Air Act implementation since the 1970 Amendments to the Act. By 
    comparison, in substantial part, Tribal authority for Clean Air Act 
    programs was expressly addressed in the Act for the first time in the 
    1990 Amendments. Tribes, therefore, are at best in the early stages of 
    developing air program expertise and planning efforts. Accordingly, EPA 
    believes it would be both infeasible and inappropriate to subject 
    Tribes to the State program submittal and related deadlines in the 
    statute as explained in more detail below.
    ---------------------------------------------------------------------------
    
        \1\4Note also that many of the submittal deadlines run from the 
    enactment of the 1990 Amendments to the Clean Air Act on November 
    15, 1990. Therefore, Tribes submitting programs in response to the 
    final rule authorizing the treatment of Tribes as States for those 
    provisions would already be substantially behind in meeting the 
    deadlines.
    ---------------------------------------------------------------------------
    
        A related set of provisions are the sanctions and other Federal 
    oversight mechanisms in the Act which are triggered when States fail to 
    meet the air program submittal deadlines called for in the Act or when 
    EPA disapproves a program submittal. In several instances, the Act 
    mandates the imposition of sanctions, such as Federal transportation 
    funding restrictions and two-to-one new source review offsets, by a 
    specific deadline if a State fails to timely submit a required program 
    or submits a program that is not fully approvable. E.g., CAA sections 
    179 and 502(d)(2)(B). Similarly, the Act often imposes specific 
    deadlines upon EPA for issuing a Federal program within a certain 
    period after a State fails to submit a program or after EPA disapproves 
    an inadequate State program. E.g., CAA sections 110(c)(1) and 
    502(d)(3). For the reasons stated above, EPA is proposing not to treat 
    Tribes in the same manner as States for certain provisions contained in 
    these sections.
        However, EPA is proposing to treat Tribes in the same manner as 
    States for those provisions that mandate the imposition of Federal 
    sanctions for failure to adequately implement or enforce an approved 
    Clean Air Act program. E.g., CAA sections 179(a)(4) and 502(i)(2). This 
    includes EPA's authority to withhold all or part of air pollution 
    control grants awarded under section 105. EPA is proposing to treat 
    Tribes in the same fashion as States for the purposes of mandatory 
    sanctions for nonimplementation of an approved Tribal program because 
    once a Tribe has sufficient legal authority and capability to have a 
    program approved, it should be treated as a similarly situated State. 
    Thus, EPA expects a Tribe to follow through on its implementation of an 
    approved program in the same manner as a State. This will provide an 
    incentive for Tribes to maintain the primary role in implementing a 
    previously approved air program and to administer effective programs. 
    In addition, EPA will also treat Tribes in the same fashion as States 
    with respect to EPA's discretionary authority to impose sanctions. 
    E.g., sections 110(m), 502(d)(2), and 502(i)(1).
        The approach EPA is proposing today regarding Clean Air Act 
    deadlines and Federal sanctions is consistent with the approach 
    outlined under Parts II.B. and II.C. of this notice. EPA's principal 
    goal is to have Tribes develop and administer their own CAA programs. 
    As indicated, EPA intends to issue guidance subsequent to this rule 
    that sets out in some detail the Federal efforts and timetables for 
    providing broader air quality protection for reservation air resources 
    in those instances when Tribes choose not to develop their own 
    programs. EPA intends to provide direct Federal Clean Air Act 
    protection on reservations if, after some reasonable time, its efforts 
    to assist Tribes in developing Tribal programs under the Act do not in 
    fact lead to Tribal program adoption and approval.
        a. National Ambient Air Quality Standards applicable implementation 
    plan submittal deadlines and related sanctions. Consistent with the 
    general discussion above, EPA is not proposing to treat Tribes in the 
    same manner as States for the general implementation plan submittal 
    deadlines specified in section 110(a)(1) of the Act. Further, Tribes 
    will not be subject to the plan submittal deadlines for nonattainment 
    areas set out in sections 172(a)(2), 182, 187, 189, and 191. EPA also 
    is not proposing to treat Tribes in the same manner as States for the 
    deadlines set out in section 124, associated with the review and 
    revision of implementation plans related to major fuel burning sources.
        However, EPA is proposing to treat Tribes in the same manner as 
    States with respect to the statutory requirements that will apply in 
    evaluating a Tribal program once a Tribe has decided to make a 
    submittal. Further, as indicated previously, EPA intends to issue 
    guidance specifying timeframes by which it will provide Federal 
    protection for Tribes that have air quality worse than the NAAQS but 
    are unable to develop their own CAA programs. The timing of Federal 
    protection will be informed by the applicable Clean Air Act NAAQS 
    attainment deadlines.
        Also consistent with the general discussion above, EPA is not 
    proposing to treat Tribes in the same manner as States for the 
    imposition of certain mandatory sanctions by EPA under section 179 
    because a Tribe has failed to submit a Tribal Implementation Plan (TIP) 
    or other requirement, has made an incomplete submittal, or has made a 
    submittal that is in part or in whole not approvable. See CAA section 
    179(a)(1)-(3); see also discussion under Part III.C.1. of this 
    preamble, concerning EPA's ``modular'' approach to Tribal Air Programs 
    (TAPs). However, EPA is proposing to treat Tribes in the same manner as 
    States for those provisions of section 179 mandating the imposition of 
    sanctions when EPA determines that a requirement of an approved plan is 
    not being implemented. See CAA section 179(a)(4). In addition, EPA is 
    proposing to treat Tribes in the same manner as States with respect to 
    EPA's discretionary authority to impose sanctions. See CAA section 
    110(m).
        EPA is not proposing to treat Tribes in the same manner as States 
    for the provisions of section 110(c)(1) that direct EPA to issue a 
    Federal Implementation Plan (FIP) within two years after EPA finds that 
    a State has failed to submit a required plan or has submitted an 
    incomplete plan or within two years after EPA has disapproved a plan in 
    whole or in part. This exception would apply only for that provision of 
    section 110(c)(1) that sets a specified date by which EPA must issue a 
    FIP. Treating Tribes in a similar manner as States under that provision 
    would be inappropriate since Tribes are not in the first instance, like 
    States, required to make submittals by a date certain, and in light of 
    the very recent initiation of Tribal air quality planning efforts. EPA 
    is proposing to treat Tribes in the same manner as States for all other 
    provisions of section 110(c)(1). Thus, EPA would continue to be subject 
    to the basic requirement to issue a FIP for affected areas within some 
    reasonable time. EPA would give substantial weight to Tribal air 
    quality needs in determining what is reasonable in particular 
    instances. Further, as discussed in Part II.B., EPA intends to spell 
    out in subsequent guidance the specific programs that EPA will 
    implement to provide CAA protection within reservations and on other 
    lands subject to Tribal jurisdiction.
        However, EPA is proposing to treat Tribes in the same manner as it 
    treats States for the State Implementation Plan/Tribal Implementation 
    Plan (SIP/TIP) call provisions under sections 110 (a)(2)(H)(ii) and 
    (k)(5) of the Act. These provisions authorize EPA to require a State to 
    revise a plan that is inadequate to assure attainment and maintenance 
    of the relevant NAAQS or is otherwise inadequate to ensure compliance 
    with applicable Clean Air Act requirements. Thus, once a Tribal 
    Implementation Plan has been approved in whole or in part as meeting an 
    applicable CAA requirement, Tribes will be similarly subject to these 
    SIP/TIP call provisions.
        b. Visibility implementation plan submittal deadlines. EPA is not 
    proposing to treat Tribes in the same manner as States for the 
    provisions of section 169A or implementing regulations requiring the 
    submittal of visibility implementation plans by specific deadlines. 
    Under today's proposal, Tribes would be treated in the same manner as 
    States for all other purposes under section 169A and its implementing 
    regulations.
        c. Interstate air pollution and visibility transport. Commission 
    plan submittal deadlines. EPA is not proposing to treat Tribes in the 
    same manner as States for those interstate commission CAA provisions 
    requiring the submittal of an applicable implementation plan by a 
    specific date. See CAA sections 169B(e)(2), 184 (b)(1) & (c)(5). 
    However, EPA is proposing to treat Tribes in the same manner as States 
    for all other interstate commission-related provisions under sections 
    169B, 176A and 184 of the CAA.
        Therefore, for example, Tribes meeting eligibility requirements for 
    these provisions of the CAA would be treated in the same manner as 
    States in identifying what areas should be included in ``interstate'' 
    air pollution and visibility transport regions and in establishing 
    commission membership. For eligible Tribes participating as members of 
    such Commissions, the Administrator would establish those submittal 
    deadlines that are determined to be practicable or, as with other non-
    participating Tribes in an affected transport region, provide for 
    Federal implementation of necessary measures.
        d. Criminal enforcement. In general, EPA is proposing that the 
    enforcement provisions of sections 113 and 114 of the Act apply to 
    Tribes in the same way that they apply to States. This would include 
    the ability of a Tribe to establish its own administrative enforcement 
    program, so that the Tribe could enforce administrative as well as 
    civil penalties. In both cases, EPA would have the authority to take 
    necessary enforcement action if the Tribe did not take such action or 
    did not enforce adequately (e.g. did not impose a sufficient penalty); 
    however, it would be most prudent for Tribes to attempt enforcement in 
    the first instance. It should also be noted that EPA has a general 
    policy of consulting with Tribal leaders and managers prior to taking 
    an enforcement action against Tribal owned or managed facilities. 
    November 8, 1984 ``EPA Indian Policy Implementation Guidance'' at p. 6.
        Section 113(c) of the CAA provides for the imposition of criminal 
    penalties. However, in certain circumstances Indian Tribes have limited 
    criminal enforcement authority. Federal law prohibits Indian Tribes 
    from holding criminal trials of or imposing criminal penalties on non-
    Indians, in the absence of a treaty or other agreement to the contrary. 
    Oliphant v. Suquamish Indian Tribe, 435 U.S. 191 (1978). In addition, 
    the Federal Indian Civil Rights Act prohibits any Indian Tribe from 
    imposing for conviction of any one offense any criminal fine greater 
    than $500. 25 U.S.C. section 1302(7). To provide for the possible 
    imposition of criminal penalties with respect to facilities located on 
    Tribal lands, each Tribe seeking approval of a CAA program that 
    requires such authority must enter into a formal Memorandum of 
    Agreement with EPA, through which it would agree to provide for the 
    timely and appropriate referral of criminal enforcement matters to the 
    EPA Regional Administrator.
        e. Title V operating permit program submittal deadlines, 
    implementation deadlines and other requirements. For the reasons stated 
    in the introduction to this section of the preamble, EPA is not 
    proposing to treat Tribes in the same manner as States for the 
    operating permit program submittal deadline set out in section 
    502(d)(1). Similarly, EPA is not proposing to treat Tribes in the same 
    manner as States under the provisions of section 502(d)(2)(B) that 
    mandate the imposition of sanctions under section 179 when a State 
    fails to timely submit a required permit program or EPA disapproves a 
    permit program. EPA also is not proposing to treat Tribes as States for 
    the provisions of section 502(d)(3) that direct EPA to promulgate and 
    administer a Federal permit program if, within two years after the 
    required submittal date, EPA has not approved a State permit program. 
    Similar to the companion provision in Title I described above (i.e., 
    section 110(c)(1)), EPA is proposing to exclude only those limited 
    provisions of section 502(d)(3) that direct EPA action by a date 
    certain (EPA would continue to be subject to the basic requirement to 
    implement a Federal permit program within a reasonable period; EPA 
    would give substantial weight to Tribal air quality needs in 
    determining what is reasonable in particular instances). These 
    provisions are inappropriate because Tribes are not in the first 
    instance directed by the statute to submit their own programs and in 
    light of the fact that the Tribal CAA program development efforts are 
    at a very preliminary stage.
        However, Tribes will be subject to the sanctions provisions of 
    section 502(i) (1)-(4) in the same manner as States. Section 502(i) 
    provides for the discretionary and mandatory imposition of section 179 
    sanctions when EPA determines that a permitting authority is not 
    adequately administering and enforcing an operating permit program, or 
    a portion thereof. Thus, once a Tribe submits an operating permit 
    program and EPA approves that program, Tribes will be subject to the 
    sanction provisions of section 502(i)(1)-(4) in the same way that 
    States are. In addition, Tribes will be treated in the same manner as 
    States with respect to EPA's discretionary authority to impose 
    sanctions under section 502(d)(2)(A).
        EPA is also not proposing to treat Tribes in the same manner as 
    States for the interim approval provisions in section 502(g) of the 
    Act. Those provisions authorize EPA to temporarily grant approval to a 
    program that in substantial part meets the requirements of the Act, but 
    that is not fully approvable. An interim approval under these 
    provisions expires on a date established by EPA but not later than two 
    years after the approval. Section 502(g) provides that the Title V 
    sanctions provisions and obligations of the Administrator to promulgate 
    a Federal operating permit program are suspended during this interim 
    period.
        The interim approval provisions allow EPA to grant States 
    submitting a substantially satisfactory permit program up to two 
    additional years to submit a fully approvable program without risk of 
    sanctions and Federal implementation. These provisions are an adjunct 
    of the statutory deadline requiring the submittal of State Title V 
    operating permit programs by November 15, 1993. If States were not in 
    the first instance required to submit operating permit programs by that 
    date certain, the relief of additional time to submit an approvable 
    program without the risk of Federal penalties would be unnecessary. As 
    stated previously, EPA is not proposing to treat Tribes in the same 
    manner as States for Title V program submittal deadlines. Accordingly, 
    EPA is also not proposing to treat Tribes in the same manner as States 
    for this related interim approval authority.
        Consistent with the general modular approach proposed with respect 
    to Tribal programs (discussed below), EPA intends to allow Tribes some 
    additional flexibility in implementing Title V programs. For example, 
    EPA may allow Tribes to extend the period for permitting affected Title 
    V sources over as long as five years from program approval. 
    Accordingly, EPA is not proposing to treat Tribes in the same manner as 
    States for those provisions of section 503(c) of the Act that direct 
    permitting authorities to establish a phased schedule for acting on 
    permit applications submitted within the first full year after the 
    effective date of a permit program (or a partial or interim program). 
    Section 503(c) provides that the phased schedule shall assure that at 
    least one-third of such permit applications will be acted on by the 
    permitting authority over a period of not to exceed three years after 
    the effective date. EPA is not proposing to subject Tribes to these 
    provisions. While it is possible that EPA may require some Tribes to 
    permit affected sources within three years, EPA nevertheless wants to 
    retain the discretion to allow Tribes up to five years to permit 
    affected Title V sources after the date of program approval.
        Further discussion of Title V requirements is set out below under 
    the portion of this notice titled ``Revisions to CAA Implementing 
    Regulations.''
        f. Small business assistance program submittal deadline and 
    compliance advisory panel requirement. EPA is not proposing to treat 
    Tribes in the same manner as States for the provisions of section 
    507(a) specifying a deadline for the submittal of plans for 
    establishing a small business stationary source technical and 
    environmental compliance assistance program. EPA also is not proposing 
    to treat Tribes in the same manner as States under section 507(e) which 
    directs States to establish a Compliance Advisory Panel. Both of these 
    provisions are inconsistent with section 301(d), which authorizes but 
    does not require Tribes to develop and submit Clean Air Act programs to 
    EPA for approval. However, if a Tribe elects to establish a Compliance 
    Advisory Panel under section 507(e), the membership specified in 
    section 507(e)(2) shall be selected by the Tribal leader, legislative 
    bodies and Tribal agencies that correspond with those identified for 
    States.
        Generally, the preceding discussion identifies those provisions of 
    the CAA for which EPA is not proposing to treat Tribes in the same 
    manner as States. EPA is proposing that Tribes be treated in the same 
    manner as States for all other provisions of the statute.
    3. Stringency of Tribal Regulations
        Under the Clean Air Act, States generally retain legal authority to 
    impose requirements that are more stringent that Federal standards. 
    Section 116 of the Act, 42 U.S.C. 7416, expressly reserves States' 
    authority to impose air pollution control requirements that are more 
    stringent than those specified under the Act. This State discretion is 
    retained except where the Act explicitly preempts or precludes the 
    establishment of stricter State standards.
        In certain instances under the Act uniformity is necessary to avoid 
    an undue burden on the interstate sale of goods. In such instances, 
    Congress has expressly prevented States from imposing stricter State 
    standards and, therefore, the Federal requirements under the Act 
    represent both the nationwide floor and ceiling. For example, section 
    209 of the Act, 42 U.S.C. section 7543, limits States' authority to 
    adopt and enforce emission standards for new motor vehicles.
        EPA is proposing to treat Tribes in the same manner as States for 
    the purposes of both section 116 of the Act and for all of the CAA 
    preemption provisions, including provisions such as section 177 that 
    authorize exclusions from preemption provisions. This will clarify 
    EPA's position that Tribes like States generally have authority to 
    exceed minimum Federal requirements. It will also clarify the fact that 
    Tribes, like States, are preempted from imposing stricter standards 
    where Congress has so specified. This will advance the overarching 
    purpose of the preemption provisions to avoid undue barriers on the 
    trade of goods in commerce.
    4. Provisions for Which no Separate Tribal Program Required.
        Under some provisions of the CAA, Tribes would have a specific role 
    by virtue of having met the minimum eligibility requirements discussed 
    in Part III.A, irrespective of whether a specific program is approved.
        For example, under section 107(d)(3), the Administrator would 
    notify an eligible Tribe of information indicating that an area within 
    the Tribe's jurisdiction should be redesignated, and the Tribe would 
    have an opportunity to provide input on that redesignation in the same 
    fashion as a State. Under section 107(d)(3) a Tribe could also submit a 
    revised designation of any area within its jurisdiction on its own 
    motion. Similarly, under section 112(r)(7)(B)(iii), risk management 
    plans would be submitted to Tribal Emergency Response Commissions.
        Under sections 169B, 176A and 184 Tribes meeting eligibility 
    requirements for such provisions shall be treated in the same manner as 
    States in identifying what areas should be included in interstate air 
    pollution and visibility transport regions and in establishing 
    commission membership.15
    ---------------------------------------------------------------------------
    
        \1\5EPA always retains any general discretionary authority to 
    make Federal Indian Reservations part of a transport Region and to 
    include representatives of Indian Tribes as interstate transport 
    Commission members.
    ---------------------------------------------------------------------------
    
        Also, treating Tribes in the same manner as States for purposes of 
    section 505(a)(2) would require permitting authorities under Title V to 
    notify an eligible Tribe that is contiguous to a State in which an 
    emission originates and whose air quality may be affected by that 
    emission, or that is within 50 miles of the emission source, of any 
    Title V permit applications that are forwarded to EPA.16 
    Permitting authorities would also be required to provide such Tribes an 
    opportunity to submit written recommendations and to notify such Tribes 
    in writing of any recommendations not accepted and the reasons why. See 
    40 CFR 70.8(b)(2). Thus, special procedural provisions would apply to 
    Tribes treated in the same manner as States for the purpose of Title V 
    notification. This Title V notification and permitting authority 
    obligation to explain any recommendations not accepted would apply 
    regardless of whether an eligible Tribe has an approved Title V 
    program.
    ---------------------------------------------------------------------------
    
        \1\6The geographic scope of Tribal lands for Title V 
    notification purposes would include any lands over which an eligible 
    Tribe has been determined to have jurisdiction, including any off-
    reservation lands.
    ---------------------------------------------------------------------------
    
        As elaborated below, EPA expects that most recognized Tribes will 
    be able to readily meet the eligibility requirements for such 
    provisions as Title V permit application notification. To promote 
    intergovernmental coordination, EPA encourages States and local 
    governments to take steps now to provide Title V notification to 
    Tribes, instead of waiting for a formal eligibility determination by 
    EPA. EPA also encourages Tribes to exercise the notification rights 
    that extend to any citizen under the Title V program in the interim 
    period preceding a Tribal eligibility determination, if necessary to 
    ensure notification. The regulations implementing the Title V operating 
    permit program generally require that permitting authorities must 
    provide adequate procedures for public notice including offering an 
    opportunity for public comment and a hearing on the draft permit. See 
    40 CFR 70.7(h). These procedures include providing notice of draft 
    permit proceedings to persons on a mailing list developed by the 
    permitting authority, including those who request in writing to be on 
    the list. See 40 CFR 70.7(h)(1). Thus, a Tribe not determined eligible 
    to be treated in the same manner as a State for notification could 
    nevertheless ensure that it receives notification of draft permits by 
    submitting a written request for such notification to appropriate 
    permitting authorities.
        EPA intends to revise existing CAA regulations to reflect this 
    Tribal authority as part of its on-going regulatory development 
    efforts. EPA also requests public comment identifying any other 
    provisions of the CAA which similarly do not require a Tribal program 
    submittal in order for a Tribe to have a role in CAA implementation.
        In all instances, including those provisions of the Act for which 
    no separate Tribal program submittal is required, it is a statutory 
    requirement that a Tribe meet the section 301(d)(2) eligibility 
    requirements, discussed in Part III.A above, before it may be treated 
    in the same manner as a State. However, as a practical matter, this 
    should not be burdensome. Often the provisions not requiring 
    accompanying program submittals are intended to promote 
    intergovernmental coordination and involve receipt or transmittal of 
    information or active participation on a multigovernmental entity. 
    Therefore, a minimal demonstration would be necessary to establish 
    Tribal capability to carry out these functions consistent with the 
    terms and purposes of statutory and regulatory requirements. Further, 
    under today's proposed streamlined procedures for determining 
    eligibility, EPA has generally simplified the demonstration that must 
    be made for eligibility approval. Taken together with the minimum 
    capability needed to carry out these particular requirements, most 
    Federally recognized Tribes are expected to be able to readily 
    demonstrate eligibility to be treated in the same manner as States for 
    CAA provisions not requiring a program submittal.
    
    C. Procedures for Review of Tribal Air Programs
    
        In general, Tribes will be required to comply with the same 
    statutory and regulatory requirements as States for the CAA programs 
    that are submitted to EPA for approval. The main difference is that 
    section 301(d) does not require Tribes to develop CAA programs. Thus, a 
    Tribe may decide to implement only those programs, or even portions of 
    programs, that are most relevant to the air quality situation on its 
    reservation or other lands subject to its jurisdiction. This ``modular 
    approach'' to Tribal CAA program development is discussed further in 
    Part III.C.1 below.
        In addition, section 301(d)(3) of the Act provides that:
    
        [t]he Administrator may promulgate regulations which establish 
    the elements of tribal implementation plans and procedures for 
    approval of tribal implementation plans and portions thereof.
    
        Section 301(d)(4) provides that:
    
        [i]n any case in which the Administrator determines that the 
    treatment of Indian tribes as identical to States is inappropriate 
    or administratively infeasible, the Administrator may provide, by 
    regulation, other means by which the Administrator will directly 
    administer such provisions so as to achieve the appropriate purpose.
    
        Further, as discussed previously, section 301(d)(2) delegates to 
    the Administrator broad discretion in determining those provisions of 
    the Act for which it is appropriate to treat Tribes as States.
        EPA interprets these provisions to mean that, both in the case of 
    TIPs and in the case of other Tribal air programs (``TAPs''), where EPA 
    finds that it is not appropriate for the same requirements to apply to 
    Tribes as to States, EPA may modify those requirements by rulemaking. 
    Accordingly, in this rulemaking EPA is proposing to make some changes 
    to the State requirements for Tribal CAA programs. In addition, EPA is 
    proposing to allow a Tribe to demonstrate to EPA that a specific CAA 
    requirement may be inappropriate for that Tribe in light of the 
    circumstances presented in a particular case. These issues are 
    discussed further in Parts III.C.2 and C.3 below.
    1. Modular Approach to Tribal Air Programs
        Because Tribal governments have limited resources, and because 
    Federal funding to support Tribal efforts is also limited, Tribes may 
    decide to implement only certain of the CAA provisions for which EPA 
    has determined it is appropriate to treat Tribes in the same manner as 
    States. In order to provide flexibility and incentive for Tribal 
    governments to assume responsibility for CAA programs, Tribes may 
    submit reasonably severable elements of programs to EPA for approval 
    instead of entire complex programs. However, in order to be approved, 
    any such submittal must meet all applicable minimum Federal 
    requirements.
        As one of the first steps in identifying Tribal priorities, EPA 
    encourages Tribes to thoroughly assess their current air quality 
    through emission inventories. Tribes should develop an accurate, 
    comprehensive and current inventory of emissions from all sources of 
    air pollution within the reservation and should project potential 
    future emissions based on likely growth. This will help Tribes estimate 
    the nature and location of air quality problems and, in turn, help 
    prioritize Tribal CAA program development.17 Note that EPA has 
    issued detailed guidance on how to conduct emission inventories.18
    ---------------------------------------------------------------------------
    
        \1\7As discussed in Part II.B. above, EPA intends to provide 
    Tribal air quality protection when Tribes do not develop such 
    programs. EPA's efforts will take place in a prioritized, phased-in 
    fashion due to limitations on Federal resources.
        \1\8See Volumes I-V of the Procedures for Emission Inventory 
    Preparation--Volume I: Emission Inventory Fundamentals, EPA-450/4-
    81-026a, Sept. 1981; Volume II: Point Sources, EPA-450/4-81-026b, 
    Sept. 1981; Volume III: Area Sources, EPA-450/4-81-026c, Sept. 1981; 
    Volume IV: Mobile Sources, EPA-450/4-81-026d, 1992; Volume V: 
    Bibliography, EPA-450/4-81-026e, Sept. 1981. The Clearinghouse for 
    Inventories and Emission Factors, (919) 541-5285, has information on 
    obtaining copies of these and other emission inventory guidance 
    documents.
    ---------------------------------------------------------------------------
    
        The results of Tribal emissions inventory assessments and 
    projections regarding future growth will help Tribes to determine 
    whether relatively few or many activities will need to be implemented 
    immediately. Some minor problems may be addressed through public 
    education and basic strategies to control the sources of pollution. 
    Other problems may require some combination of monitoring, modelling 
    and the development of Tribal plans and regulations. If future growth 
    in emissions is projected, Tribes should also consider developing 
    programs for the Prevention of Significant Deterioration of Air Quality 
    (``PSD''). See Addendum A, ``Title I'' discussion (overview of the PSD 
    program) and Part III.D.
        Where the emissions inventory reveals a potential air quality 
    problem, air quality monitoring can help further characterize the 
    potential problem. EPA has issued regulations and guidance on air 
    quality monitoring. EPA's air quality monitoring regulations are set 
    out at 40 CFR part 58. Among other things, Appendices A through G to 40 
    CFR part 58 describe air quality network design, criteria for citing 
    air quality monitors and quality assurance criteria.
        In prioritizing Tribal efforts, Tribes should also evaluate the 
    expertise and resource requirements needed to implement desired 
    programs. As stated above, Tribes will be given the flexibility of 
    implementing programs in a modular fashion. Thus, Tribes can develop 
    reasonably severable CAA programs to address particular air quality 
    problems and submit them to EPA for approval.
        For example, a Tribe having a PM-10 air quality problem may develop 
    a partial PM-10 nonattainment implementation plan that addresses 
    pollution from existing sources but does not, for example, contain a 
    program governing the review of new sources that propose to locate in 
    the area. EPA would not decline to approve the submittal until the 
    Tribe developed a nonattainment new source review program for PM-10 or 
    developed a plan for addressing an ozone pollution problem.
        Similarly, a Tribe having relatively good air quality and 
    anticipating likely new source growth in the area may choose to focus 
    resources on developing a PSD program. The CAA's PSD permit program 
    provides for preconstruction review of the air quality impacts 
    associated with proposed new or modified major stationary sources in 
    areas meeting air quality standards. The permitting process is to 
    ensure that the proposed source employs state-of-the-art control 
    technology, does not cause or contribute to an exceedance of air 
    quality standards, and does not adversely impact National Parks and 
    Wilderness areas.
        A Tribe may develop and submit to EPA for approval a PSD permit 
    program alone. A Tribe expecting certain categories of new source 
    growth may develop and submit to EPA for approval a PSD permit program 
    addressing those sources or source categories.19 Under the rule 
    proposed today, if the implementation plan elements or other partial 
    CAA program submitted by the Tribe is reasonably severable and meets 
    the applicable minimum requirements under Federal law, EPA will approve 
    the submittal.
    ---------------------------------------------------------------------------
    
        \1\9As described elsewhere in this notice, EPA will issue PSD 
    permits for any sources not covered by an approved PSD program.
    ---------------------------------------------------------------------------
    
    2. Procedures for Reviewing and Approving Tribal Implementation Plans 
    (``TIPs'')
        The CAA contains provisions which specifically govern EPA's review 
    and processing of the State implementation plans (SIPs) developed under 
    Title I of the Act to provide for attainment and maintenance of the 
    national ambient air quality standards (NAAQS). See Addendum A, ``Title 
    I'' discussion. These provisions are set forth in section 110(k) of the 
    Act. The CAA authorizes EPA to amend, by regulation, the procedures 
    governing the review and processing of analogous Tribal implementation 
    plans (TIPs). See sections 110(o) and 301(d)(3).
        In broad terms, section 110(k)(1) provides the criteria EPA is to 
    apply in determining whether a submittal is complete and therefore 
    warrants further review and action. See also 57 FR 13,498, 13,565 
    (April 16, 1992). The EPA's completeness criteria for SIP submittals 
    are set out at 40 CFR Part 51, Appendix V. EPA is required to make 
    completeness determinations within 60 days of receiving a SIP 
    submittal. However, a submittal is deemed complete by operation of law 
    if a completeness determination has not been made by EPA within 6 
    months of EPA's receipt of the submittal. Section 110(k)(1) & 57 FR at 
    13,565.
        Section 110(k)(3)-(4) address EPA's review of submittals that have 
    been deemed complete. For example, section 110(k)(3) provides that EPA 
    shall fully approve submittals that meet all of the applicable 
    requirements of the Act, and partially approve and disapprove 
    submittals that meet only a portion of the applicable requirements. 
    Section 110(k)(4) further authorizes EPA to conditionally approve 
    commitments by a State to adopt specific enforceable measures by a date 
    certain that is no later than one year after the approval. The 
    conditional approval is automatically converted to a disapproval if the 
    State fails to fulfill the commitment. Section 110(k)(2) directs EPA to 
    act on a submittal within 12 months of determining it to be complete. 
    The Act calls for the imposition of sanctions and the issuance of a 
    Federal implementation plan when a State fails to submit a required 
    plan or such plan is disapproved. See sections 110(c)(1), 110(m) and 
    179 of the Act. Guidance on EPA's implementation of these and related 
    provisions is set out in a July 9, 1992 memorandum from John Calcagni, 
    ``Processing of State Implementation Plan (SIP) Submittals.''
        As indicated previously, the Act does not require Tribes to submit 
    TIPs. For that reason and other reasons specified above, EPA is not 
    proposing to treat Tribes in the same manner as States for the 
    implementation plan submittal deadlines specified in the Act. See Part 
    III.B above. Further, EPA is proposing to accept any reasonably 
    severable portion of an applicable Tribal implementation plan.
        EPA is proposing to apply the completeness criteria to TIPs in the 
    manner described below. If a Tribe submits a reasonably severable 
    portion of a TIP that meets applicable completeness criteria, EPA will 
    continue to process the submittal. If the submittal is incomplete EPA 
    will return it to the Tribe, identifying the deficiencies. EPA will 
    exercise one of two options with respect to a complete TIP submittal. 
    EPA will fully approve any portion of a TIP if it is reasonably 
    severable and meets the applicable Federal requirements. For any 
    portion that is not approvable, EPA will disapprove the submittal and 
    work closely with the Tribe to correct the identified deficiencies. 
    However, as noted earlier in Part III.B, EPA's disapproval of a TIP 
    will not have the mandatory sanctions consequences that apply to States 
    under section 179 of the Act or the consequences under section 
    110(c)(1) of requiring a FIP within two years of the disapproval.
        As with SIPs, TIPs should be submitted to the EPA Regional Office 
    for the region in which the Tribe is located. Addendum B to this notice 
    contains a list and the addresses of EPA's Regional Offices and a map 
    indicating the regions that they encompass. Any Tribes that have not 
    yet been determined to be eligible by EPA for CAA program purposes must 
    submit the materials described in Part III.A above, in conjunction with 
    any TIP submittal.
    3. Procedures for Reviewing Other Tribal Air Programs (``TAPs'')
        EPA will review all other Tribal air program submittals in light of 
    the applicable statutory and regulatory requirements as well as EPA 
    policy, including the modular concept described above. EPA is proposing 
    in today's rule to treat Tribes in the same manner as States for all of 
    the provisions of the CAA, with the limited exceptions identified in 
    Part III.B & C above. However, EPA recognizes that in proposing this 
    rule and obtaining comments, EPA may not have anticipated and 
    identified all of those requirements applicable to States that would be 
    infeasible or inappropriate to apply to Tribes. Therefore, EPA is 
    proposing to add a regulatory provision that will generally allow 
    Tribes to demonstrate to EPA, in conjunction with the submittal of a 
    TAP, that treatment of a Tribe in the same manner as a State for a 
    particular provision is inappropriate or administratively infeasible. 
    EPA will review the Tribal demonstration and take appropriate action.
        TAPs should be submitted to the Regional Office for the region in 
    which the Tribe is located. See Addendum B. EPA will internally review 
    TAPs in the same manner as it reviews State submittals for the specific 
    CAA programs presented, consulting with and obtaining the concurrence 
    of the appropriate EPA offices. A determination that a TAP is not 
    approvable or that a Tribe has not met the general eligibility 
    requirements described in Part III.A above does not preclude the Tribe 
    from making subsequent submittals at a future date. If EPA determines 
    that a Tribal submittal is deficient or incomplete, EPA will work 
    closely with the Tribe to identify and correct the deficiencies.
    
    D. Revisions to CAA Implementing Regulations
    
        The regulations implementing the CAA span many pages of the Code of 
    Federal Regulations. In today's action, EPA is proposing to add new 40 
    CFR part 49, which will address the Tribal CAA authority described in 
    this notice. To implement this authority EPA is also proposing to add a 
    general requirement in part 49 that eligible Tribes will be treated in 
    the same manner as States under all of EPA's existing, currently 
    effective regulations implementing the Clean Air Act, except those 
    regulations implementing provisions of the CAA for which EPA has 
    concluded that it would be inappropriate to treat Tribes as States. 
    Such exceptions are described in detail in Part III.B of this notice.
        EPA will undertake a major effort, in conjunction with forthcoming 
    rulemaking initiatives and its periodic review and revision of existing 
    regulations, to make conforming changes to all CAA implementing 
    regulations. As examples, today's proposed rule contains conforming 
    modifications to 40 CFR Parts 50 and 81. The discussion below also 
    explains in detail how the existing regulations implementing new source 
    review permitting requirements and Title V permit program requirements 
    would be affected by the action proposed today. The general regulatory 
    provision applying existing, currently effective regulations to Tribes, 
    as described in the previous paragraph, will address the application of 
    existing regulations during the interim period in which conforming 
    changes are made to CAA regulations.
        Further, in Part IV below, EPA outlines potential ways in which 
    EPA's administration of Federal financial assistance for Tribes may 
    differ from States. Thus, EPA is proposing to make corresponding 
    changes to regulations implementing Federal financial assistance 
    requirements.
    1. 40 CFR Part 35--State [Tribal] and Local Assistance
        EPA is proposing to make changes to its regulations at 40 CFR Parts 
    35 related to Federal financial assistance. The proposed changes are 
    described in detail in Part IV of today's preamble.
    2. 40 CFR Part 49--Tribal Clean Air Act Authority
        The general Tribal authority provisions proposed in today's action 
    will be codified at 40 CFR part 49. This includes the following: EPA's 
    proposed interpretation of relevant jurisdictional issues, discussed in 
    Part II; the proposed simplified eligibility criteria, discussed in 
    Part III.A; the proposed finding that Tribes should generally be 
    treated in the same manner as States under the CAA, the specific 
    exceptions to this general finding, and the proposed provision 
    authorizing Tribes to identify and request additional exceptions on an 
    ad hoc basis, discussed in Part III.B, and; the general procedures for 
    reviewing Tribal air programs, discussed in Part III.C.
    3. 40 CFR Part 50--National Primary and Secondary Ambient Air Quality 
    Standards
        EPA is proposing conforming changes to 40 CFR part 50. These 
    modifications clarify that references to the term ``State'' in 40 CFR 
    Part 50 include, as appropriate, ``Indian Tribe'' and ``Indian 
    country.'' The revisions proposed clarify, for example, that under 40 
    CFR 50.2(c), the promulgation of NAAQS shall not be considered in any 
    manner to allow significant deterioration of existing air quality in 
    any portion of Indian country (as defined in 18 U.S.C. 1151). They also 
    clarify that in the same way that section 50.2(d) provides that States 
    retain discretion to establish ambient air quality standards more 
    stringent than the NAAQS, the establishment of NAAQS in no way 
    prohibits Indian Tribes from establishing ambient air quality standards 
    that are more stringent than the NAAQS.
    4. 40 CFR Part 51--Requirements for Preparation, Adoption, and 
    Submittal of Implementation Plans.
        The regulations in Part 51 contain the basic requirements for state 
    implementation plans (SIP). However, EPA has not systematically updated 
    40 CFR Part 51 since the passage of the 1990 Amendments to the Clean 
    Air Act. In many instances these regulatory requirements are 
    inconsistent with the revised law and are therefore inoperative as a 
    matter of law. See CAA section 193 (``regulation * * * in effect before 
    the date of enactment of the Clean Air Act Amendments of 1990 shall 
    remain in effect according to its terms, except to the extent * * * 
    inconsistent with any provision of this Act.'')
        To facilitate SIP development under the amended law, EPA has issued 
    guidance documents. These documents reflected EPA's preliminary 
    interpretations of the relevant Act requirements at that time. See, 
    e.g., ``General Preamble for the Implementation of Title I of the Clean 
    Air Act Amendments of 1990'' (57 FR 13498, April 16, 1992; 57 FR 18070, 
    April 28, 1992); ``New Source Review (NSR) Program Supplemental 
    Transitional Guidance on Applicability of New Part D NSR Permit 
    Requirements'' (Issued by Office of Air Quality Planning and Standards 
    Director on September 3, 1992); NOX Supplement to the General 
    Preamble (57 FR 55620, November 25, 1992).
        EPA intends to update both the existing and new source regulatory 
    requirements in Part 51 to make clear which regulatory provisions were 
    rendered nugatory by the 1990 Amendments and which continue to have 
    legal force.
        Interim implementation of applicable Title I requirements for 
    Tribal lands should be guided by EPA's preliminary interpretations of 
    the revised Title I requirements and the interpretive statements in 
    this notice.
    5. 40 CFR Part 52--Approval and Promulgation of Implementation Plans
        Federal PSD Permitting. EPA has issued rules that provide for 
    Federal implementation of the PSD permit program (preconstruction 
    permit requirements applicable to major stationary sources or major 
    modifications20 in areas that currently meet the NAAQS). 40 CFR 
    52.21. In the same manner as States, Federal implementation of a PSD 
    program on Tribal lands applies in any case where the Tribe does not 
    have an approved PSD program.
    ---------------------------------------------------------------------------
    
        \2\0Note that a proposed source in certain listed source 
    categories is ``major'' for PSD purposes if it has the potential to 
    emit 100 tons per year of any pollutant regulated under the Act. 
    Other sources are ``major'' for PSD if their emissions may exceed 
    250 tons per year. The regulatory definitions of ``major stationary 
    source'' and ``major modification'' for the PSD program are set out 
    at 40 CFR 52.21(b) (1), (2).
    ---------------------------------------------------------------------------
    
        EPA is undertaking a comprehensive regulatory effort to revise its 
    PSD rules (and its nonattainment NSR program, see below) consistent 
    with some of the changes made to the substantive PSD program under the 
    revised Act (and as a part of a broader reform initiative). Since these 
    revised rules have not yet been promulgated, EPA has issued detailed 
    guidance addressing transitional and interim implementation issues 
    associated with the changes made by the 1990 Amendments. See 57 FR 
    18070 at 18074-77 (April 28, 1992) (Appendix D--``New Source Review 
    (NSR) Program Transitional Guidance,'' March 11, 1991). At least until 
    any further guidance is provided in EPA's NSR rulemaking, EPA's review 
    and issuance of PSD permits for applicable sources proposing to locate 
    on Tribal lands will be in accordance with the previously-issued PSD 
    transitional permitting guidance, today's guidance, and 40 CFR 52.21, 
    to the extent that the existing provisions of 40 CFR 52.21 are 
    consistent with the amended Act.21 See section 193 of the Act.
    ---------------------------------------------------------------------------
    
        \2\1The 1977 Amendments to the CAA authorized Indian tribes to 
    redesignate the classification of lands within the exterior 
    boundaries of a reservation for PSD planning purposes. Section 
    164(a), 42 U.S.C. 7474(c); Nance v. EPA, 645 F.2d 701 (9th Cir. 
    1981), cert. den'd, 451 U.S. 1081 (1981). Area classifications for 
    PSD determine the maximum increment of degradation that is 
    permissible in a clean air area. Tribal authority to redesignate 
    areas for this purpose is set forth in 40 CFR 52.21. Tribes continue 
    to have this authority under the Act as amended in 1990.
    ---------------------------------------------------------------------------
    
        Federal NSR Permitting. 40 CFR 52.24(c) provides that 40 CFR part 
    51, Appendix S (``Offset Ruling'') governs the issuance of NSR permits 
    (required for the construction and operation of new and modified major 
    stationary sources in nonattainment areas) where approved State rules 
    are not in place. The Offset Ruling sets out EPA's interpretation 
    regarding the conditions that are designed to ensure that sources and 
    source modifications subject to the NSR requirements will be controlled 
    to the greatest degree possible and that more than equivalent 
    offsetting emission reductions will be obtained from existing sources, 
    thus ensuring progress toward achievement of the NAAQS.
        The 1990 Amendments to the CAA added new provisions to the Act 
    addressing the substantive NSR permitting requirements. See, e.g., 
    sections 173, 182 and 189(b)(3) of the Act, 42 U.S.C. 7503, 7511a and 
    7513a(b)(3). As with the new changes to the PSD program, EPA has issued 
    guidance addressing the implementation of the revised nonattainment NSR 
    requirements in the period before EPA's comprehensive regulations are 
    adopted. See 57 FR 13498 (April 16, 1992); 57 FR 18070, 18075-77 (April 
    28, 1992) (Appendix D--``New Source Review (NSR) Program Transitional 
    Guidance,'' March 11, 1991); ``New Source Review (NSR) Program 
    Supplemental Transitional Guidance on Applicability of New Part D NSR 
    Permit Requirements'' (Sept. 3, 1992). In the interim period before EPA 
    issues further guidance through its Federal nonattainment NSR 
    rulemaking to implement the amended Act, EPA intends to conduct 
    nonattainment NSR permitting on Tribal lands consistent with the Offset 
    Ruling and the transitional EPA guidance addressing the revisions to 
    the Act.
    6. 40 CFR Part 70--State [and Tribal] Operating Permit Programs
        This discussion explains how the regulations at 40 CFR Part 70 
    implementing the Title V operating permit program would be affected by 
    today's proposed action. EPA is currently developing Federal rules to 
    be codified in 40 CFR Part 71 that will authorize direct Federal 
    implementation of Title V permit program requirements for States and 
    Tribes that lack adequate program coverage.
        Program Submittal Deadlines and Processing. Program submittal 
    deadlines are set out at 40 CFR 70.4(a). Tribes will not be compelled 
    to develop and submit Title V permit programs to EPA for approval. 40 
    CFR 70.4(e) addresses the processing of Title V program submittals. Any 
    Tribal submittal that is incomplete or disapproved will be returned to 
    the Tribe following such determination. To the extent possible, EPA 
    will work with the Tribe to remedy deficiencies in the Tribal program. 
    However, the timeframes governing EPA's processing of Tribal submittals 
    will be the same as those applicable to State submittals.
        Program Coverage. The regulations call for States to issue permits 
    that assure compliance with ``each applicable requirement * * * by all 
    part 70 sources''. 40 CFR 70.4(b)(3)(i); see also 40 CFR 70.6(a)(1) 
    (``[e]ach permit issued under this part shall include * * * [e]mission 
    limitations and standards * * * that assure compliance with all 
    applicable requirements at the time of permit issuance''). Approvable 
    Tribal programs must address all affected Part 70 sources within a 
    Tribe's jurisdiction.
        Deadlines for Permit Applications and Processing of Applications. 
    40 CFR 70.5(a) requires the owner or operator of Part 70 sources to 
    submit applications within 12 months of becoming subject to the 
    program. 40 CFR 70.7(a)(2) requires the permitting authority to act on 
    an application within 18 months of receipt. To ensure that permits are 
    expeditiously submitted and reviewed, these deadlines will apply with 
    equal force to Tribal programs, to the extent that Tribes elect to 
    develop and implement such programs.
        40 CFR 70.4(b)(11) requires States to have a transition plan for 
    acting on applications received within the first 12 months after 
    approval, such that the State will act on one-third of the applications 
    in each of the first three years of its program. This requirement 
    overrides the 18-month requirement for acting on applications during 
    the first 3 years. As discussed in Part III.B.2.e above, the 3-year 
    implementation requirement in section 503(c) is among the provisions of 
    the CAA for which EPA is not proposing to treat Tribes in the same 
    manner as States. For Tribal programs, this initial program phase-in 
    will be based on a schedule developed by the Regional Office in 
    conjunction with each Tribe. This case-by-case approach will ensure 
    that any transition adequately accounts for the scope of Tribal program 
    coverage, the universe of Part 70 sources and the extent of Tribal 
    expertise and resources. However, EPA is also proposing to provide that 
    in no case shall such a transitional schedule exceed 5 years from the 
    date of EPA's approval of the Tribal program.
        Enforcement. Required enforcement authority is set out in 40 CFR 
    70.11. As stated above, Federal law prohibits Indian Tribes from 
    holding criminal trials of or imposing criminal penalties on non-
    Indians, in the absence of a treaty or other agreement to the contrary. 
    Oliphant, at 435 U.S. 191. In addition, Federal law prohibits Indian 
    Tribes from imposing for conviction of any one offense a criminal fine 
    greater than $500. 25 U.S.C. section 1302(7). Tribes requesting Title V 
    program approval will be required to enter into formal Memorandum of 
    Agreement with EPA, through which it would agree to provide for the 
    timely referral of criminal enforcement matters to the appropriate EPA 
    Regional Administrator.
        Operational Flexibility. The three operational flexibility 
    provisions at 40 CFR 70.4(b)(12) will be optional for Tribes as will 40 
    CFR 70.6(a)(8), (10) (emissions trading in the permit) and 40 CFR 
    70.6(a)(9) which requires States to include alternative operating 
    scenarios, if requested, in their permits.
        Permit Issuance, Revisions Procedures. Generally, for the 
    procedures governing permit issuance and revision, EPA will treat 
    Tribes in the same manner as it treats States. While Tribes will have 
    some flexibility regarding the form and manner of public notice 
    requirements under 40 CFR 70.7(h), the minimum period for public notice 
    will be 30 days for Tribes as with States.
        Tribes, like States, must have authority to reopen permits for 
    cause, as required by 40 CFR 70.7(f).
        Application content requirements. These requirements are set out in 
    40 CFR 70.5. These requirements will apply with equal force to sources 
    within Tribal jurisdiction, since EPA believes that the information 
    specified in this provision constitutes the minimum information that is 
    essential to the issuance of an effective permit.
        Permit content requirements. These are found in 40 CFR 70.6(a), 
    (c). The permit content requirements will generally apply to Tribes in 
    the same manner in which they apply to States. These remaining 
    requirements are necessary to an effective permit. These requirements 
    include 40 CFR 70.6(a)(3), which requires the State and, under today's 
    proposal, the Tribal permitting authority to insert monitoring 
    requirements into the permit where the underlying monitoring 
    requirement is deficient.
        Judicial Review. 40 CFR 70.4(b)(3)(x)-(xii) requires States to 
    provide an opportunity for judicial review of a final permit action and 
    for the State's failure to take such final action. Tribes will have to 
    meet the same requirements.
        EPA Veto and Citizen Petition Process. 40 CFR 70.8 requires States 
    to provide EPA with a 45-day review period and opportunity for veto. 
    The provision further specifies that no permit may issue prior to the 
    expiration of that period or at all over an EPA veto. It also provides 
    citizens the right to petition EPA to veto a State-issued permit. These 
    provisions will apply with equal force to Tribal programs.
        40 CFR 70.8(b) also requires that State programs provide that the 
    permitting authority notify any affected States of each draft permit. 
    This requirement to provide notice will apply with equal force to 
    Tribal programs. Further, any State or Tribal permitting authority will 
    provide notice to any affected Tribe in the same manner as the 
    regulations require notification to affected States. See Part III.B.4 
    above.
        General Revisions. References to States and State officials will 
    include Tribes and corresponding Tribal officials.
    7. 40 CFR Part 81--Designation of Areas for Air Quality Planning 
    Purposes.
        EPA is proposing conforming regulatory changes to part 81, in light 
    of today's proposal to treat Indian Tribes in the same manner in which 
    it treats States under the air quality designation provisions set out 
    at section 107 of the Act.
        Pursuant to section 107(d)(3) of the CAA EPA would notify eligible 
    Indian Tribes that EPA has information indicating that an air quality 
    designation for an Indian Reservation should be revised. Then, as with 
    the Governor of an affected State, the relevant Tribal leader would 
    have 120 days to reply to EPA. In addition, eligible Indian Tribes 
    would on their own initiative have authority to submit a redesignation 
    request to EPA for approval in the same way that States and the 
    relevant Governors are authorized to under section 107(d)(3)(D) of the 
    Act.
        EPA is proposing to add explicit definitions of Indian Reservation, 
    Indian Tribe and State to 40 CFR Part 81. EPA is also proposing 
    revisions to subpart C of Part 81 to reflect the authority that 
    eligible Indian Tribes may have to initiate revisions to designations.
        Future air quality designations for eligible Tribes will be 
    codified under an entry for the affected Indian Tribe in subpart C, 
    Part 81 that is the same as State air quality designations under Part 
    81.
    
    IV. Federal Financial Assistance
    
    A. Sources of Funding Assistance
    
        Financial assistance for Indian Tribes under the Clean Air Act is 
    available via two principal authorities: grants for the support of air 
    pollution planning and control programs under section 105 (42 U.S.C. 
    7405); and grants for investigations, demonstrations and studies into 
    the causes, effects, extent, prevention and control of air pollution 
    under section 103 (42 U.S.C. 7403).
        In addition to these potential sources of funds under the Clean Air 
    Act, EPA can provide Tribes funding assistance for air quality work 
    under the Agency's Indian Environmental General Assistance Grants 
    Program (40 CFR part 35, subpart Q). These grants provide funds to 
    Tribes for planning, developing and establishing the capacity to 
    implement environmental programs on Indian lands, regardless of the 
    program's environmental media.
        Each of these assistance and fee programs carries various statutory 
    and/or administrative requirements which are discussed and explained in 
    this portion of the preamble. Proposed regulatory revisions are set out 
    at the end of this notice.
    
    B. Tribal Eligibility for Air Grant Assistance
    
        In today's action, EPA is proposing to modify certain regulatory 
    and administrative limitations on the manner in which Indian Tribes 
    qualify for and obtain financial assistance under the Act. EPA also 
    seeks comment from interested parties on options in meeting the non-
    Federal matching requirements for grants obtained under section 105 
    authority. The financial assistance options are described below.
    1. Section 103 Air Assessment Grants
        Tribes may apply for grant assistance to assess reservation air 
    quality conditions under authority of section 103(b)(3) of the Act. 
    Section 103(b)(3) allows EPA to fund investigations, research, surveys, 
    and studies concerning any specific problem of air pollution in 
    cooperation with any air pollution control agency. Tribes may undertake 
    specific projects to assess Tribal air quality conditions at any time. 
    Typically, Tribes will undertake such projects as an initial step, 
    prior to initiating development and adoption of Tribal regulations to 
    control air resources. Section 103(b)(3) grant funds are not available 
    for developing Tribal capacity.
        Funds provided under section 103 are available to Tribes at up to a 
    95% Federal share. Thus each recipient must contribute at least five 
    percent of the total allowable project costs. The Agency believes that 
    the five percent cost sharing requirement should be retained.
        EPA rules limit award of section 103 grants to a maximum of five 
    years for any one project period. 40 CFR 40.125-1. This should allow a 
    reasonable amount of time for Tribal recipients of assistance to assess 
    the nature of their air quality and determine the extent of any air 
    quality problems. However, the Agency will carefully consider requests 
    for deviations under 40 CFR 31.6 for extensions of grant project 
    periods. Further, section 103 is available for multiple project 
    periods. Finally, Tribes that have received previous section 103 grants 
    will remain eligible for future grants to fund appropriate projects at 
    any time. The determination of each Tribal applicant's continued 
    eligibility and the appropriate authority of award will be the 
    responsibility of the appropriate Regional Administrator. As this 
    suggests, Tribes not establishing eligibility to be treated in the same 
    manner as States under section 301(d) will remain eligible, as they are 
    currently, for assistance under section 103(b)(3).
    2. Section 105 Air Program Grants
        The Agency encourages eligible Tribes to apply for continuing 
    environmental assistance under authority of section 105 and 301(d) of 
    the Act, particularly after a comprehensive assessment of reservation 
    air quality conditions. Section 105 allows EPA to make grants for 
    implementing programs for the prevention and control of air pollution 
    or implementation of air quality standards.
        Currently, in order to be eligible to receive a grant under section 
    105, a recipient must meet the definition of an air pollution control 
    agency specified in section 302(b) of the Act. This definition includes 
    ``[a]n agency of an Indian tribe.'' See section 302(b)(5). Thus, 
    section 302(b)(5) authorizes 105 grants to Tribes that have not 
    established their eligibility to be treated in the same manner as 
    States.
        The Act expressly provides that until the promulgation of these 
    regulations, EPA may continue to provide section 105 grants to eligible 
    Tribes on this basis. See section 301(d)(5). EPA believes that section 
    301(d)(5) was intended to ensure that Tribes would be able to receive 
    financial assistance while this regulation was being developed. The 
    Agency does not believe that this provision, which on its face is 
    designed to ensure Tribal access to funds, must be read to require that 
    EPA cease awarding section 105 grants to Tribes not meeting the 
    eligibility requirements after this regulation is issued.
        Consistent with this legal interpretation, this regulation provides 
    two avenues for Tribes to obtain section 105 assistance. A Tribe that 
    does not establish eligibility for treatment in the same manner as a 
    state under section 301 but that is ``an agency of an Indian tribe,'' 
    and therefore meets the definition of an ``air pollution control 
    agency'' under section 302(b)(5), can obtain 105 funds, subject to the 
    same limitations that apply to other 105 grant recipients. These 
    limitations include the statutory requirement that the grant recipient 
    contribute matching funds for 40% of the allowable project costs.
        Alternatively, Tribes that establish their eligibility to be 
    treated in the same manner as States under section 301(d) may, like 
    States, receive section 105 financial assistance. However, assistance 
    to Tribes pursuant to 301(d) can be provided without being subject to 
    every limitation that applies to such grants when made to States. 
    Section 301(d)(4) expressly provides that, in cases where it is not 
    appropriate to treat Tribes as identical to States, EPA ``may provide, 
    by regulation, other means by which the [Agency] will directly 
    administer such provisions so as to achieve the appropriate purpose.'' 
    EPA believes that requiring the 40% match as a prerequisite for 
    assistance under section 105 could impose an undue financial burden on 
    Tribes; the Agency further believes it can best administer section 105 
    to achieve the purpose of maximizing tribal access to this assistance 
    by providing relief from the cost share requirement. However, based on 
    statutory language, this special relief will, as noted above, only be 
    available for Tribes that have established their eligibility to be 
    treated in the same manner as states and therefore are eligible for 
    financial assistance pursuant to section 301(d).
        This proposal seeks comments on the appropriate level of Tribal 
    cost share for a section 105 grant match, from a minimum of 5% to a 
    maximum of 40%. This proposal also seeks comments on the establishment 
    of a phase-in period for Tribes to meet whatever match is ultimately 
    required for section 105 grants.
        A 40% match of air grant funds under section 105 is currently 
    required from States. However, when these air grants were originally 
    awarded some 25 years ago, a 25% State match was required. Given the 
    lack of Tribal financial resources, there is concern that even this 
    lower level of Tribal match may not be appropriate in many instances. 
    In addition, the Agency believes it may be appropriate to allow a Tribe 
    establishing eligibility to be treated in the same manner as a state to 
    begin receiving 105 assistance with a lower match, which would 
    gradually be phased upward until it reaches some appropriate level.
        During the development of the regulation, EPA discussed the option 
    of developing a sliding scale, with differing levels of match based on 
    tribal demonstrations of ability to pay. This option is not being 
    proposed in this regulation, due to the Agency's concern that requiring 
    some tribes to pay a higher match than others could create barriers to 
    participation by those tribes, and that all tribes experience resource 
    constraints.
        The Agency also recognizes that its approach should be consistent 
    with President Clinton's April 29 Presidential Memorandum on 
    ``Government-to-Government Relations with Native American Tribal 
    Governments.'' 59 FR 22,951 (May 4, 1994). That Memorandum directs 
    agencies to ``take appropriate steps to remove any procedural 
    impediments to working directly and effectively with tribal governments 
    on activities that affect the * * * governmental rights of the 
    tribes.'' The Agency believes minimizing the burdens to participation 
    by all tribes may be the approach most consistent with this directive.
        Although the Agency is not proposing a sliding scale, it requests 
    comments on whether such an approach might be feasible and the criteria 
    that could be used to determine the matching requirement for each grant 
    recipient. The Agency solicits comments on: An appropriate initial 
    match level equal to or exceeding five percent; the length appropriate 
    for a phase-in period (if any) of the match; the rate at which the 
    match would be phased upward; and an appropriate level for a permanent 
    match requirement.
        The Clean Air Act also establishes one purpose for which Tribes may 
    not be treated in the same manner as states. Under section 301(d)(1)(A) 
    Tribes may not be treated in the same manner as States for purposes of 
    section 105(b)(2) which ensures that each State applying for assistance 
    have made available to it for application (but not necessarily for 
    award) a minimum of one half of one percent of the total section 105 
    amount annually appropriated under the Act.
    3. Tribal Agencies and Consortia
        Section 103 and 105 assistance is currently available to an 
    individual Tribe because it constitutes an air pollution control agency 
    under section 302(b)(5). The Agency also believes it may be appropriate 
    to provide assistance to groups of tribes, typically tribes with air 
    resources that are either contiguous or similar in their 
    characteristics, when those tribes join into consortia for the purpose 
    of applying for and managing the air quality financial assistance 
    described above. A consortium is a partnership between two or more 
    Indian tribal governments authorized by their governing bodies. Tribes 
    can join into consortia in circumstances they find appropriate. The 
    ``economies of scale'' made possible through Tribal consortia 
    arrangements may allow for the assumption of air resource management 
    responsibilities that may not otherwise be possible with small, single-
    Tribe environmental agencies.
        Consortia will have discretion in demonstrating how they will meet 
    the matching funds requirement. Therefore, when a consortium reaches 
    the point that it must provide matching funds to obtain grant funds, 
    the consortium may combine its resources to meet the requirement in any 
    manner it deems appropriate.
    
    C. Use of EPA General Assistance Grants
    
        EPA has recently issued regulations governing the use of Indian 
    Environmental General Assistance Grants as required under 42 U.S.C. 
    4368b. Indian Environmental General Assistance Program Act of 1992; 42 
    U.S.C. 4368b, (58 FR 63876, December 2, 1993) codified at 40 CFR part 
    35, subpart Q. The regulations establish requirements for applying for 
    and utilizing general assistance funds. The Indian Environmental 
    General Assistance Grants may be used by Tribes to fund program 
    development activities in various environmental media, including air, 
    and are thus considered to be an important means of establishing 
    overall Tribal environmental program capability. Moreover, the award of 
    these grants in no way precludes a Tribe from applying for, and being 
    awarded, air grant assistance under section 103 or section 105 of the 
    Act.
    
    D. Additional Administrative Requirements
    
        Each Tribal application for assistance must still meet the Agency's 
    general administrative requirements for grants which are set forth in 
    more detail in 40 CFR Parts 31, 32 and 34 and which are not modified by 
    this regulation. Additional requirements specific to section 105 air 
    grants are detailed in 40 CFR 35 and, for section 103, in 40 CFR Part 
    40.
    
    V. Miscellaneous
    
    A. Executive Order (EO) 12866
    
        Section 3(f) of EO 12866 defines ``significant regulatory action'' 
    to mean any regulatory action that is likely to result in a rule that 
    may:
        (1) Have an annual effect on the economy of $100 million or more or 
    adversely affect in a material way the economy, a sector of the 
    economy, productivity, competition, jobs, the environment, public 
    health or safety, or State, local or tribal governments or communities;
        (2) Create a serious inconsistency or otherwise interfere with an 
    action taken or planned by another agency;
        (3) Materially alter the budgetary impact of entitlements, grants, 
    user fees, or loan programs or the rights and obligations of recipients 
    thereof; or
        (4) Raise novel legal or policy issues arising out of legal 
    mandates, the President's priorities, or the principles set forth in 
    this Executive order.
        This proposed rule was determined not to be a significant 
    regulatory action. A draft of this proposed rule was nevertheless 
    reviewed by the Office of Management and Budget (OMB) prior to 
    publication because of anticipated public interest in this action 
    including potential interest by Indian Tribes and State/local 
    governments.
        EPA has placed the following information related to OMB's review of 
    this proposed rule in the public docket referenced at the beginning of 
    this notice:
        (1) Materials provided to OMB in conjunction with OMB's review of 
    this proposed rule; and
        (2) Materials that identify substantive changes made between the 
    submittal of a draft proposed rule to OMB and this notice, and that 
    identify those changes that were made at the suggestion or 
    recommendation of OMB.
    
    B. Regulatory Flexibility Act (RFA)
    
        Under the RFA, 5 U.S.C. sections 601-612, EPA must prepare, for 
    rules subject to notice-and-comment rulemaking, initial and final 
    Regulatory Flexibility Analyses describing the impact on small 
    entities. The RFA defines small entities as follows:
    
    --Small businesses. Any business which is independently owned and 
    operated and is not dominant in its field as defined by Small Business 
    Administration regulations under section 3 of the Small Business Act.
    --Small governmental jurisdictions. Governments of cities, counties, 
    towns, townships, villages, school districts or special districts, with 
    a population of less than fifty thousand.
    --Small organizations. Any not-for-profit enterprise which is 
    independently owned and operated and is not dominant in its field.
    
        However, the requirement of preparing such analyses is inapplicable 
    if the Administrator certifies that the rule will not, if promulgated, 
    have a significant economic impact on a substantial number of small 
    entities. 5 U.S.C. 605(b).
        The proposed rule, if promulgated, will not have a significant 
    economic impact on a substantial number of small entities. Many Indian 
    Tribes may meet the definition of small governmental jurisdiction 
    provided above. However, the proposed rule does not place any mandates 
    on Indian Tribes. Rather, it authorizes Indian Tribes to demonstrate 
    their eligibility to be treated in the same manner as States under the 
    Clean Air Act, to submit CAA programs for specified provisions and to 
    request Federal financial assistance as described elsewhere in this 
    preamble. Further, the proposed rule calls for the minimum information 
    necessary to effectively evaluate Tribal applications for eligibility, 
    CAA program approval and Federal financial assistance. Thus, EPA has 
    attempted to minimize the burden for any Tribe that chooses to 
    participate in the programs provided in this proposed rule.
        The proposed regulation will not have a significant impact on a 
    substantial number of small businesses. Any additional economic impact 
    on the public resulting from implementation of this proposed regulation 
    is expected to be negligible, since Tribal regulation of these 
    activities is limited to areas within Tribal jurisdiction and, in any 
    event, EPA has regulated or may regulate these activities in the 
    absence of Tribal CAA programs.
        The proposed regulation will not have a significant impact on a 
    substantial number of small organizations for the same reasons that the 
    proposed regulation will not have a significant impact on a substantial 
    number of small businesses.
        Accordingly, I certify that this proposed regulation, if 
    promulgated, will not have a significant economic impact on a number of 
    small entities.
    
    C. Executive Order (EO) 12875
    
        EO 12875 is intended to reduce the imposition of unfunded mandates 
    upon State, local and Tribal governments. To that end, it calls for 
    Federal agencies to refrain, to the extent feasible and permitted by 
    law, from promulgating any regulation that is not required by statute 
    and that creates a mandate upon a State, local, or Tribal government, 
    unless funds for complying with the mandate are provided by the Federal 
    government or the Agency first consults with affected State, local and 
    Tribal governments.
        The issuance of this proposed rule is required by statute. Section 
    301(d) of the CAA directs the Administrator to promulgate regulations 
    specifying those provisions of the Act for which it is appropriate to 
    treat Indian Tribes as States. Moreover, this proposed rule would not 
    place mandates on Indian Tribes. Rather, as discussed in section V.B 
    above, this rule authorizes or enables Tribes to demonstrate their 
    eligibility to be treated in the same manner as States under the Clean 
    Air Act and to submit CAA programs for the provisions specified by the 
    Administrator. Further, the proposed rule also explains how Tribes 
    seeking to develop and submit CAA programs to EPA for approval may 
    qualify for Federal financial assistance.
    
    D. Paperwork Reduction Act
    
        OMB has approved the information collection requirements pertaining 
    to grants applications contained in this rule under the provisions of 
    the Paperwork Reduction Act, 44 U.S.C. 3501, et seq. and has assigned 
    OMB control number 2030-0020.
        This collection of information pertaining to the grants application 
    process has an estimated reporting burden averaging 29 hours per 
    response and an estimated annual recordkeeping burden averaging 3 hours 
    per respondent. These estimates include time for reviewing 
    instructions, searching existing data sources, gathering and 
    maintaining the data needed, and completing and reviewing the 
    collection of information.
        The information collection requirements in this proposed rule 
    pertaining to an Indian Tribe's application for eligibility to be 
    treated in the same manner as a State or ``treatment as a State'' have 
    been submitted for approval to OMB under the Paperwork Reduction Act, 
    44 U.S.C. 3501, et seq. An Information Collection Request document has 
    been prepared by EPA (ICR No. 1676.01) and a copy may be obtained from 
    Sandy Farmer, Information Policy Branch; EPA; 401 M St., SW. (Mail Code 
    2136); Washington, DC 20460 or by calling (202) 260-2740.
        This collection of information for Treatment in the Same Manner as 
    States (TISMAS) to carry out the Clean Air Amendments has an estimated 
    reporting burden of 20 annual responses, averaging 40 hours per 
    response and an estimated annual recordkeeping burden averaging 800 
    hours. These estimates include time for reviewing instructions, 
    searching existing data sources, gathering and maintaining the data 
    needed, and completing and reviewing the collection of information.
        Send comments regarding these burden estimates or any other aspect 
    of these collections of information, including suggestions for reducing 
    this burden to Chief, Information Policy Branch; EPA; 401 M St., SW. 
    (Mail Code 2136); Washington, DC 20460; and to the Office of 
    Information and Regulatory Affairs, Office of Management and Budget, 
    Washington, DC 20503, marked ``Attention: Desk Officer for EPA.'' The 
    final rule will be accompanied with responses to OMB or public comments 
    on the information collection requirements contained in this proposal.
    
    VI. Request for Public Comments
    
        EPA requests public comments on all aspects of today's proposal, 
    including the following: EPA's proposed interpretation of the Clean Air 
    Act as delegating to Tribes jurisdiction over all air resources within 
    the exterior boundaries of the reservation; EPA's proposed 
    interpretation of the term ``reservation''; EPA's proposed 
    interpretation that in enacting the CAA, Congress found that the 
    activities regulated under the Act constitute a class of activities 
    that, if left unregulated, could have serious and substantial adverse 
    effects on public health and welfare, and accordingly, that these 
    activities would generally be within the inherent civil regulatory 
    authority of Tribes; EPA's position regarding Federally-administered 
    Clean Air Act programs to provide protection for Tribal air resources; 
    EPA's proposed implementation of its policy for streamlining 
    eligibility determinations; the CAA provisions for which EPA is 
    proposing to treat Indian Tribes as States, and the proposed exceptions 
    that EPA has identified in this rule; EPA's general approach to 
    encourage Tribal participation by allowing Tribes to submit reasonably 
    severable portions of CAA programs; EPA's proposed procedures for 
    reviewing Tribal air programs, including Tribal implementation plans 
    developed under Title I of the CAA; EPA's proposed revisions to its 
    implementing regulations, and; EPA's proposed administration of Federal 
    financial assistance to Tribes.
    
    VII. Electronic Filing of Comments
    
        A public docket has been established for this proposed rule under 
    docket number ``A-93-3087'' (including comments and data submitted 
    electronically as described below). The public docket is located in 
    M1500, 401 M Street, Washington, DC 20460. The information contained in 
    this public docket, including printed, paper versions of electronic 
    comments is available for inspection from 8 a.m. to 4 p.m., Monday thru 
    Friday, excluding legal holidays. Starting October 1, 1994, the docket 
    will be open 8 a.m. to 5:30 p.m., excluding legal holidays.
         As part of an interagency ``streamlining'' initiative, EPA is 
    experimenting with submission of public comments on selected rulemaking 
    actions electronically through the Internet in addition to accepting 
    comments in traditional written form. This proposed rule is one of the 
    rulemaking actions selected by EPA for this experiment. From the 
    experiment, EPA will learn how electronic commenting works, and any 
    problems that arise can be addressed before EPA adopts electronic 
    commenting more broadly in its rulemaking activities. Electronic 
    commenting through posting to the EPA Bulletin Board or through the 
    Internet using the ListServe function raise some novel issues that are 
    discussed below in this Section.
        To submit electronic comments, persons can either ``subscribe'' to 
    the Internet ListServe application or ``post'' comments to the EPA 
    Bulletin Board. To ``Subscribe'' to the Internet ListServe application 
    for this proposed rule, send an e-mail message to: 
    listserver@unixmail.rtpnc.epa.gov that says `` Subscribe RIN-2060-AE95 
     .'' Once you are subscribed to the ListServe, 
    comments should be sent to: RIN-2060-AE95@unixmail.rtpnc.epa.gov.
        For online viewing of submissions and posting of comments, the 
    public access EPA Bulletin Board is also available by dialing 202-488-
    3671, enter selection ``DMAIL,'' user name ``BB____USER'' or 919-541-
    4642, enter selection ``MAIL,'' user name ``BB____USER.'' When dialing 
    the EPA Bulletin Board type  at the opening message. When the 
    ``Notescaret]'' prompt appears, type ``open RIN-2060-AE95'' to 
    access the posted messages for this document. To get a listing of all 
    files, type ``dir/all'' at the prompt line. Electronic comments can 
    also be sent directly to EPA at: [email protected]
        To obtain further information on the electronic comment process, or 
    on submitting comments on this proposed rule electronically through the 
    EPA Bulletin Board or the Internet ListServe, please contact John A. 
    Richards (Telephone: 202-260-2253; FAX: 202-260-3884; Internet: 
    richards.john@epamail.epa.gov).
        Persons who comment on this proposed rule, and those who view 
    comments electronically, should be aware that this experimental 
    electronic commenting is administered on a completely public system. 
    Therefore, any personal information included in comments and the 
    electronic mail addresses of those who make comments electronically are 
    automatically available to anyone else who views the comments.
        Commenters and others outside EPA may chose to comment on the 
    comments submitted by others using the RIN-2060-AE95 ListServe or the 
    EPA Bulletin Board. If they do so, those comments as well will become 
    part of EPA's record and included in the public docket for this 
    rulemaking. Persons outside EPA wishing to discuss comments with 
    commenters or otherwise communicate with commenters but not have those 
    discussions or communications sent to EPA and included in the EPA 
    rulemaking record and public docket should conduct those discussions 
    and communications outside the RIN-2060-AE95 ListServe or the EPA 
    Bulletin Board.
        EPA will transfer all comments received electronically in the RIN-
    2060-AE95 ListServe or the EPA Bulletin Board, in accordance with the 
    instructions for electronic submission, into printed, paper form as 
    they are received and will place the paper copies in the official 
    rulemaking docket which will also include all comments submitted 
    directly in writing. All the electronic comments will be available to 
    everyone who obtains access to the RIN-2060-AE95 ListServe or the EPA 
    Bulletin Board; however, the official rulemaking docket is the paper 
    docket maintained at the address in ADDRESSES at the beginning of this 
    document. (Comments submitted only in written form will not be 
    transferred into electronic form and thus may be accessed only by 
    reviewing them in the EPA Docket as described above.)
        Because the electronic comment process is still experimental, EPA 
    cannot guarantee that all electronic comments will be accurately 
    converted to printed, paper form. If EPA becomes aware, in transferring 
    an electronic comment to printed, paper form, of a problem or error 
    that results in an obviously garbled comment, EPA will attempt to 
    contact the comment submitter and advise the submitter to resubmit the 
    comment either in electronic or written form. Some commenters may 
    choose to submit identical comments in both electronic and written form 
    to ensure accuracy. In that case, EPA requests that commenters clearly 
    note in both the electronic and written submissions that the comments 
    are duplicated in the other medium. This will assist EPA in processing 
    and filing the comments in the rulemaking docket.
        As with ordinary written comments, EPA will not attempt to verify 
    the identities of electronic commenters nor to review the accuracy of 
    electronic comments. EPA will take such commenters and comments at face 
    value. Electronic and written comments will be placed in the rulemaking 
    docket without any editing or change by EPA except to the extent 
    changes occur in the process of converting electronic comments to 
    printed, paper form.
        EPA will address significant electronic comments either in a notice 
    in the Federal Register or in a response to comments document placed in 
    the rulemaking docket for this proposed rule. EPA will not respond to 
    commenters electronically other than to seek clarification of 
    electronic comments that may be garbled in transmission or conversion 
    to printed, paper form as discussed above. Any communications from EPA 
    employees to electronic commenters, other than those described in this 
    paragraph, either through Internet or otherwise are not official 
    responses from EPA.

    Addendum A to Preamble--General Description of Clean Air Act 
    Programs
    
        The Clean Air Act is codified in the United States Code (U.S.C.) at 
    42 U.S.C. 7401-7671q. There are six different Titles that comprise the 
    Act as codified.1 The following discussion contains a broad 
    overview of each Title with the objective of providing a general road 
    map to the Clean Air Act. The discussion is not, and is not intended to 
    be, a comprehensive and detailed discussion of Clean Air Act 
    requirements.
    ---------------------------------------------------------------------------
    
        \1\The Clean Air Act is Chapter 85, Title 42 of the U.S. Code. 
    The Titles of the Act are actually subchapters of the Code. To avoid 
    confusion, these subchapters will be referred to herein as Titles of 
    the Act.
    ---------------------------------------------------------------------------
    
        To help illustrate the potential effect of today's proposal, the 
    discussion at times refers to Tribes as if the authority proposed today 
    was in effect. However, this authority will not be in place until EPA 
    takes final action on today's proposed rule. The process preceding 
    final action includes the consideration of public comments on today's 
    proposal that may alter the final rule.
    
    Title I--National Ambient Air Quality Standards and Stationary Source 
    Requirements.
    
        EPA has established national ambient air quality standards (NAAQS) 
    for certain air pollutants for the protection of the public health 
    (``primary'' standards) and welfare (``secondary'' standards). CAA 
    section 109, 42 U.S.C. 7409. EPA establishes these standards after a 
    thorough review of the latest scientific studies and literature 
    indicating the kind and extent of identifiable effects on public health 
    or welfare which may be expected from the presence of such pollutants 
    in the ambient air in varying quantities. CAA section 108, 42 U.S.C. 
    7408. EPA has established health and welfare NAAQS for six different 
    pollutants: ozone, carbon monoxide, particulate matter, sulfur dioxide, 
    nitrogen dioxide, and lead. These standards are codified in 40 CFR Part 
    50.
        Areas nationwide are ``designated'' based on whether they meet the 
    NAAQS. Areas that do not meet the NAAQS are designated 
    ``nonattainment.'' CAA section 107, 42 U.S.C. 7407. States containing 
    such areas are required to develop State implementation plans (SIPs) 
    which must bring the areas into attainment as expeditiously as 
    practicable. If EPA finalizes today's rule as proposed, Tribes may 
    submit such implementation plans (``TIPs''). Title I contains general 
    requirements that SIPs and, as appropriate, TIPs must meet (CAA section 
    110(a)(2), 42 U.S.C. 7410(a)(2)) as well as planning provisions (e.g., 
    inventorying of emissions) and control requirements applicable to 
    existing stationary sources in nonattainment areas. CAA sections 171-
    192, 42 U.S.C. 7501-7514a.
        EPA has issued detailed guidance that sets out its preliminary 
    views on the implementation of the air quality planning requirements 
    applicable to areas that are not in attainment with the NAAQS. This 
    guidance is titled the ``General Preamble for the Implementation of 
    Title I of the Clean Air Act Amendments of 1990'' (or ``General 
    Preamble''). See 57 FR 13,498 (April 16, 1992) and 57 FR 18,070 (April 
    28, 1992). The General Preamble has been supplemented with further 
    guidance on Title I requirements. See 57 FR 31,477 (July 16, 1992) 
    (announcing the availability of draft guidance for lead nonattainment 
    areas and serious PM-10 nonattainment areas); 57 FR 55,621 (Nov. 25, 
    1992) (guidance on NOx RACT requirements in ozone nonattainment 
    areas). EPA will likely issue further supplements to the General 
    Preamble.
        Title I also contains control requirements applicable to new (or 
    modified) major stationary sources. ``Major'' sources are those 
    emitting more than a certain amount of pollutant per year. Sources 
    subject to the New Source Review (``NSR'') or Prevention of Significant 
    Deterioration (``PSD'') requirements may not initiate construction, as 
    it is defined under the law, without obtaining an NSR or PSD permit 
    from the State or Tribe (or from EPA, if the State or Tribe has not 
    been authorized by EPA to administer the program).
        The nonattainment NSR permit program applies only in nonattainment 
    areas. The Act directs EPA to require States and authorizes EPA to 
    permit Tribes to develop NSR permit programs as part of their SIPs or 
    TIPs. The NSR permit program requires strict control technology and 
    emissions reductions from nearby sources to ``offset'' emissions 
    released for proposed new (or modified) major stationary sources in 
    nonattainment areas. E.g., CAA section 173, 42 U.S.C. 7503.
        The PSD program applies to certain new or modified major stationary 
    sources in areas that currently have air quality meeting the NAAQS. To 
    prevent the air quality in these areas from significantly 
    deteriorating, the Clean Air Act requires States in such clean air 
    areas to develop permit programs that impose control requirements on 
    new or modified major stationary sources. The permit program must also 
    require an assessment of the air quality impacts of proposed sources to 
    ensure that new sources will not cause or contribute to an exceedance 
    of the NAAQS or certain allowed ``increments'' of air quality 
    degradation. CAA sections 160-169, 42 U.S.C. 7470-7479. Since all areas 
    of the country meet at least one of the NAAQS, all States are required 
    to have a PSD program for areas within their jurisdiction. EPA 
    administers PSD programs for States that have failed to submit 
    approvable programs. In today's action, EPA is proposing to authorize 
    Tribes to submit PSD programs for EPA approval.
        There is also a minor source permit program, under CAA section 
    110(a)(2)(C), 42 U.S.C. 7410(a)(2)(C), and 40 CFR 51.160-164 which 
    requires SIPs to include a program regulating the modification and 
    construction of any stationary source, regardless of size or attainment 
    status, as necessary to assure that the NAAQS are achieved. In today's 
    action, EPA is proposing to authorize Tribes to include minor source 
    permit programs as part of their TIPs in the same manner as States.
        Finally, EPA also issues new source performance standards 
    (``NSPS'') that affected new or modified stationary sources must meet 
    in both attainment and nonattainment areas. States are required to 
    submit, and EPA is proposing that Tribes be authorized to submit, plans 
    similar to SIPs or TIPs that provide for the implementation and 
    enforcement of certain requirements for certain pollutants regulated by 
    NSPS. CAA sections 111(d), 129, 42 U.S.C. 7411(d), 7429.
        Conformity. Section 176 of the Act, 42 U.S.C. 7506, prohibits 
    Federal agencies from supporting or providing financial assistance for 
    activities that do not conform to an approved SIP or TIP. The 
    restriction extends to State, Tribal and local transportation plans or 
    projects that are approved or funded by a Federal agency.
        Visibility. Title I also requires States in which certain mandatory 
    ``class I'' Federal areas (certain national parks, wildernesses and 
    international parks as specified in section 162(a), 42 U.S.C. 7472(a)) 
    are located, or States whose emissions may affect such areas, to 
    include provisions in their SIPs to remedy and prevent visibility 
    impairment in those areas. CAA sections 169A & 169B, 42 U.S.C. 7491 & 
    7492. In today's action, EPA is proposing to authorize Tribes to submit 
    visibility TIPs.
        Interstate Pollution Provisions. Section 126 of the Act, 42 U.S.C. 
    7426, authorizes States to petition the Administrator to find that a 
    major source or group of stationary sources in one State emits air 
    pollutants that contribute significantly to nonattainment, interfere 
    with maintenance of the NAAQS, or interfere with measures under the PSD 
    or visibility protection programs in another State. See also section 
    110(a)(2)(D) of the Act. EPA is proposing that these provisions apply 
    to Tribes in the same fashion that they apply to States so that a Tribe 
    or State may take such action to remedy pollution from an upwind Tribe 
    or State.
        In addition, sections 169B, 176A and 184, 42 U.S.C. 7492, 7506a & 
    7511c, were added to the Act in the 1990 Amendments and contain 
    provisions for cooperatively addressing interstate pollution problems. 
    These provisions authorize (and, in some instances, direct) the 
    establishment of interstate transport commissions to address regionwide 
    visibility impairment, ozone pollution and other NAAQS pollution 
    issues. The Governors of the affected States (or their designees) 
    represent the State members of the commissions. Generally, the 
    commissions develop and transmit recommendations to EPA on the specific 
    issues the commissions are charged with addressing. Thus, the 
    commissions provide a vehicle for facilitating interstate cooperation 
    and input in addressing air pollution problems that require a regional 
    solution due to pollutant transport across political boundaries. In 
    today's action, EPA is proposing to extend this authority to Tribes. 
    Among other things, Tribes would be authorized to petition the 
    Administrator for establishment of commissions and Tribal leaders 
    included in commission membership in the same fashion as State leaders.
        Hazardous Air Pollutants. The provisions governing the emissions of 
    hazardous air pollutants are also contained in Title I. EPA is directed 
    to issue control technology standards (``maximum achievable control 
    technology'' or ``MACT'') covering 189 hazardous air pollutants. CAA 
    section 112, 42 U.S.C. 7412. Section 112 also contains provisions to 
    prevent and minimize the consequences of accidental releases of, among 
    other things, extremely hazardous substances. States or, as proposed 
    today, Tribes may develop and submit to EPA for approval, programs 
    implementing both the hazardous air pollutant emission standards and 
    accidental release requirements.
        Enforcement and Information Collection. The Clean Air Act general 
    Federal enforcement provisions are contained in Title I. Section 113 of 
    the CAA, 42 U.S.C. 7413, authorizes the imposition of both civil and 
    criminal penalties for violation of Clean Air Act requirements. It also 
    contains provisions authorizing EPA to pay cash awards to persons 
    furnishing information leading to a criminal conviction or certain 
    civil penalties.
        Section 114 of the Act, 42 U.S.C. 7414, contains provisions 
    granting EPA broad authority to require, among other things, 
    recordkeeping, monitoring and right of entry and inspection. It also 
    contains provisions authorizing EPA to delegate this authority to 
    States and, as proposed in today's rule, Tribes.
        Federal Facilities. Section 118 of the CAA, 42 U.S.C. 7418, 
    provides that Federal facilities must comply with all Federal, State 
    and local air pollution requirements to the same extent as 
    nongovernmental agencies unless expressly exempted by the President. 
    EPA is proposing to extend this authority to Tribal air pollution 
    requirements.
        Financial Assistance. The provisions governing the issuance of 
    Federal financial assistance to air pollution control agencies are set 
    out in Title I. CAA sections 103 & 105, 42 U.S.C. 7403 & 7405. The 
    phrase ``air pollution control agency'' for this purpose is, in turn, 
    defined in CAA section 302(b), 42 U.S.C. 7602(b), and expressly 
    includes ``[a]n agency of an Indian tribe.'' An ``Indian tribe'' is 
    defined in CAA section 302(r). See discussion below under Title III/
    Definitions. Issues associated with the award of Federal financial 
    assistance to Tribes are addressed in more detail in the SUPPLEMENTARY 
    INFORMATION section of this notice.
    
    Title II--Mobile Sources
    
        This Title contains the provisions of the Clean Air Act addressing 
    mobile sources (e.g., automobiles, trucks, off-road vehicles). It 
    contains provisions addressing motor vehicle emission standards as well 
    as standards for aircraft and non-road vehicles and engines. See, e.g., 
    CAA sections 202, 213 & 231, 42 U.S.C. 7521, 7547 & 7571. It also 
    provides for the regulation of motor vehicle and other fuels, including 
    registration requirements, requirements for new fuels and fuel 
    additives as well as provisions for reformulated gasoline and low 
    sulfur diesel fuel. CAA section 211, 42 U.S.C. 7545.
        Significant provisions of this Title preempt in whole or in part 
    the issuance of State standards. For example, section 209 of the CAA, 
    42 U.S.C. 7543, precludes any State or political subdivision from 
    controlling emissions from new motor vehicles. EPA may waive this 
    prohibition for California, and other States may adopt California 
    standards. CAA sections 209(b) & 177, 42 U.S.C. 7543 & 7507. Similarly, 
    except in limited circumstances, States are precluded from enforcing 
    controls on motor vehicle fuels that are different from those required 
    by EPA. CAA section 211(c)(4), 42 U.S.C. 7545(c)(4). Therefore, the 
    motor vehicle and fuel requirements in Title II generally are issued 
    and administered by EPA unless the statute contemplates and a State 
    qualifies for special treatment or waiver of the preemption provisions.
        However, some Title II provisions are administered by the States 
    through the SIP system established under Title I. For example, States 
    containing certain carbon monoxide and ozone nonattainment areas are 
    required to develop and submit to EPA for approval a SIP revision 
    establishing a clean-fuel vehicle program for motor vehicle fleets. CAA 
    section 246, 42 U.S.C. 7586. States containing certain carbon monoxide 
    nonattainment areas are required to develop and submit to EPA for 
    approval a SIP revision establishing an oxygenated gasoline program. 
    CAA section 211(m), 42 U.S.C. 7545(m). In today's action, EPA is 
    proposing to extend this State-implemented authority to Tribes.
    
    Title III--Citizen Suits
    
        Section 304 of the Act, 42 U.S.C. 7604, authorizes any person who 
    provides the minimum required advance notice to bring a civil action 
    against: any person, including any governmental entity or agency, who 
    is in violation of an emission limit; the Administrator of EPA where he 
    or she fails to carry out a non-discretionary duty under the Clean Air 
    Act or has unreasonably delayed agency action; any person who proposes 
    to construct or constructs any new or modified major stationary source 
    without a NSR or PSD permit that meets the requirements of the Act 
    (described previously); and any person who is alleged to be in 
    violation of such permit. The term ``person'' ``includes an individual, 
    corporation, partnership, association, State, municipality, political 
    subdivision of a State, and any agency, department, or instrumentality 
    of the United States and any officer, agent, or employee thereof.'' 
    Section 302(e), 42 U.S.C. 7602(e). The Federal district courts are 
    granted jurisdiction over such legal action. In today's action, EPA is 
    proposing that Tribes be subject to these provisions in the same manner 
    that States are.
        Judicial Review of Final Agency Action. Section 307(b), 42 U.S.C. 
    7607(b), contains the provisions governing judicial review of final 
    agency action issuing or approving regulations. Section 307(b) 
    specifies in which U.S. Court of Appeals an action is to be brought and 
    by what date a petition for review must be filed with the appropriate 
    Court of Appeals.
        Definitions. Section 302, 42 U.S.C. 7602, contains definitions for 
    many of the terms used in the Clean Air Act. The term ``Indian tribe'' 
    is among the terms defined in this section and is defined as ``any 
    Indian tribe, band, nation, or other organized group or community, 
    including any Alaska Native village, which is Federally recognized as 
    eligible for the special programs and services provided by the United 
    States to Indians because of their status as Indians.'' CAA section 
    302(r). Not all of the CAA definitions are set out in section 302. 
    Terms often are defined in the specific Titles in which they appear.
        Outer Continental Shelf. Section 328, 42 U.S.C. 7627, provides for 
    regulation of sources located on the Outer Continental Shelf (OCS) 
    offshore all the States except Texas, Louisiana, Mississippi and 
    Alabama. These sources must comply with EPA's rule on OCS requirements, 
    which generally set forth requirements that are the same as the 
    applicable requirements in the corresponding onshore area that pertain 
    to the attainment and maintenance of ambient air quality standards and 
    to PSD. If States develop and submit to EPA an adequate program, EPA 
    can delegate implementation and enforcement of these provisions to 
    States. EPA is proposing to extend such authority to Tribes in today's 
    action.
    
    Title IV--Acid Deposition.
    
        This program calls for phased nationwide emission reductions in 
    sulfur dioxide (SO2) of approximately 10 million tons from 1980 
    levels from fossil fuel-fired electric utility units. These reductions 
    are achieved through the purchase and sale of a fixed number of 
    SO2 ``allowances.'' Each allowance entitles the holder to emit one 
    ton of SO2. Through this emissions trading program, owners of 
    ``affected'' units that can reduce emissions efficiently can sell 
    excess allowances to owners of units where it is more costly to obtain 
    the required reductions, thereby achieving emissions reductions in a 
    cost-effective manner.
        The acid rain program also calls for reductions in nitrogen oxides 
    of approximately 2 million tons from 1980 levels from coal-fired 
    electric utility units. These reductions are obtained by requiring 
    affected sources to comply with certain emission limitations. In many 
    situations, compliance may be demonstrated by averaging the emissions 
    among different utility units.
        The Title IV program is a Federal program during Phase I, from 
    1995--1999. However, during Phase II, which begins in the year 2000, 
    States will issue the acid precipitation portion of the operating 
    permits addressed below under Title V. 42 U.S.C. 7651-7651o. In today's 
    rule, EPA is proposing to extend this Phase II permitting authority to 
    Tribes.
    
    Title V--Operating Permits Program.
    
        Title V of the Act requires States to develop and submit to EPA an 
    operating permit program.2 Title V calls for the permitting of 
    certain sources by certain deadlines. Operating permits are to contain 
    all of the Clean Air Act requirements applicable to such sources. The 
    program is intended to promote regulatory certainty and enforceability. 
    Title V also provides for the collection of fees by the permitting 
    agency that reflect the reasonable costs of the permit program. 42 
    U.S.C. 7661-7661e. EPA has issued rules specifying the minimum 
    requirements for State permit programs. 57 FR 32,250 (July 21, 1992). 
    EPA is proposing to extend Title V operating permit program authority 
    to Tribes in today's rule.
    ---------------------------------------------------------------------------
    
        \2\ Note that this operating permit program is not the same as 
    the NSR and PSD permit programs described previously that, by 
    contrast, require construction permits.
    ---------------------------------------------------------------------------
    
        Small Business Assistance Program. Title V also contains provisions 
    requiring States to adopt a small business stationary source technical 
    and environmental compliance assistance program, which is to be 
    incorporated into the SIP described under Title I. 42 U.S.C. 7661f. EPA 
    is proposing to authorize Tribes to submit such assistance programs.
    
    Title VI--Phaseout of Ozone-Depleting Chemicals.
    
        This Title provides for the phase-out of the production of certain 
    substances that deplete stratospheric ozone as well as providing other 
    restrictions on the use of such substances. It is a Federally 
    established and federally managed program. 42 U.S.C. 7671-7671q. Among 
    other things, it implements the Montreal Protocol, a multinational 
    agreement addressing damage to stratospheric ozone.

    Code of Federal Regulations is proposed to be amended as set forth 
    below:
    
    PART 35--STATE AND LOCAL ASSISTANCE
    
        1. The authority cite for part 35, subpart A, continues to read as 
    follows:
    
        Authority: Secs. 105 and 301(a) of the Clean Air Act, as amended 
    (42 U.S.C. 7405 and 7601(a)); Secs. 106, 205(g), 205(j), 208, 319, 
    501(a), and 518 of the Clean Water Act, as amended (33 U.S.C. 1256, 
    1285(g), 1285(j), 1288, 1361(a) and 1377); secs. 1443, 1450, and 
    1451 of the Safe Drinking Water Act (42 U.S.C. 300j-2, 300j-9 and 
    300j-11); secs. 2002(a) and 3011 of the Solid Waste Disposal Act, as 
    amended by the Resource Conservation and Recovery Act of 1976 (42 
    U.S.C. 6912(a), 6931, 6947, and 6949); and secs. 4, 23, and 25(a) of 
    the Federal Insecticide, Fungicide and Rodenticide Act, as amended 
    (7 U.S.C. 136(b), 136(u) and 136w(a)).
    
        2. Section 35.105 is amended by revising the definitions for 
    ``Eligible Indian Tribe'', ``Federal Indian reservation'', and the 
    first definition for ``Indian Tribe'', and by removing the second 
    definition for ``Indian Tribe'' to read as follows:
    
    
    Sec. 35.105  Definitions.
    
    * * * * *
        Eligible Indian Tribe means:
        (1) For purposes of the Clean Water Act, any federally recognized 
    Indian Tribe that meets the requirements set forth at 40 CFR 130.6(d); 
    and
        (2) For purposes of the Clean Air Act, any federally recognized 
    Indian Tribe that meets the requirements set forth at Sec. 35.220.
        Federal Indian reservation means for purposes of Clean Water Act or 
    the Clean Air Act, all land within the limits of any Indian reservation 
    under the jurisdiction of the United States Government, notwithstanding 
    the issuance of any patent, and including rights-of-way running through 
    the reservation.
        Indian Tribe means:
        (1) Within the context of the Public Water System Supervision and 
    Underground Water Source Protection grants, any Indian Tribe having a 
    Federally recognized governing body carrying out substantial 
    governmental duties and powers over a defined area.
        (2) For purposes of the Clean Water Act, any Indian Tribe, band, 
    group, or community recognized by the Secretary of the Interior and 
    exercising governmental authority over a Federal Indian reservation.
         (3) For purposes of the Clean Air Act, any Indian Tribe, band, 
    nation, or other organized group or community, including any Alaskan 
    Native Village, which is recognized by the Secretary of the Interior 
    and which exercises governmental authority over a Federal Indian 
    reservation or other defined area.
    * * * * *
        3. Section 35.205 is amended by adding a sentence to the end of 
    paragraphs (a) and (b) to read as follows:
    
    
    Sec. 35.205  Maximum Federal share.
    
        (a) * * * For Indian tribes establishing eligibility pursuant to 
    Sec. 35.220, the Regional Administrator may provide financial 
    assistance to in an amount up to ______ (amount to be determined) of 
    the approved costs of planning, developing, establishing, or improving 
    an air pollution control, and up to ______ (amount to be determined) of 
    the approved costs of maintaining that program.''
        (b) * * * The Regional Administrator may provide agencies of one or 
    more tribes that have established eligibility pursuant to Sec. 35.220 
    which have substantial responsibility for carrying out an applicable 
    implementation plan under section 110 of the Clean Air Act up to ______ 
    (amount to be determined) of the approved costs of planning, 
    developing, establishing, or approving an air pollution control program 
    and up to ______ (amount to be determined) of the approved costs of 
    maintaining that program.
        4. Section 35.210 is amended by adding a paragraph (c) to read as 
    follows:
    
    
    Sec. 35.210  Maintenance of effort.
    
    * * * * *
        (c) The requirements of paragraphs (a) and (b) of this section 
    shall not apply to Indian tribes that have established eligibility 
    pursuant to Sec. 35.220.
        5. Section 35.215 is revised to read as follows:
    
    
    Sec. 35.215  Limitations.
    
        (a) The Regional Administrator will not award section 105 funds to 
    an interstate, intertribal or intermunicipal agency which does not 
    provide assurance that it can develop a comprehensive plan for the air 
    quality control region which includes representation of appropriate 
    State, interstate, local, and international interests.
        (b) The Regional Administrator will not award section 105 funds to 
    a local, interstate, or intermunicipal agency without consulting with 
    the appropriate official designated by the Governor or Governors of the 
    State or States affected or the appropriate official of any affected 
    Indian tribe or tribes.
        (c) The Regional Administrator will not disapprove an application 
    for or terminate or annul an award of section 105 funds without prior 
    notice and opportunity for a public hearing in the affected State or 
    area within Tribal jurisdiction or in one of the affected States or

    Sec. 49.3  General Tribal Clean Air Act authority.
    
        Tribes meeting the eligibility criteria of Sec. 49.6 shall be 
    treated in the same manner as States with respect to all provisions of 
    the Clean Air Act and implementing regulations, except for those 
    provisions identified in Sec. 49.4 and the regulations that implement 
    those provisions.
    
    
    Sec. 49.4  Clean Air Act provisions inapplicable to Tribes.
    
        The following provisions of the Clean Air Act and any implementing 
    regulations are not applicable to Tribes:
        (a) Specific plan submittal and implementation deadlines for NAAQS-
    related requirements, including but not limited to such deadlines in 
    sections 110(a)(1), 172(a)(2), 182, 187, 189, 191 of the Act.
        (b) The specific deadlines associated with the review and revision 
    of implementation plans related to major fuel burning sources in

        (c) The mandatory imposition of sanctions under section 179 of the 
    Act because of a failure to submit an implementation plan or required 
    plan element by a specific deadline, or the submittal of an incomplete 
    or disapproved plan or element.
        (d) The ``within 2 years'' clause in section 110(c)(1) of the Act. 
    The inapplicability of this specific clause does not in any way curtail 
    the general authority delegated to the Administrator under section 
    110(c)(1) to issue a Federal implementation plan upon the failure of a 
    Tribe to make a required submission, upon a finding that the plan or 
    plan revision submitted by a Tribe is incomplete or in response to 
    EPA's disapproval of a Tribal implementation plan in whole or in part.
        (e) Specific visibility implementation plan submittal deadlines 
    established under section 169A of the Act.
        (f) Specific implementation plan submittal deadlines related to 
    interstate commissions under sections 169B(e)(2), 184(b)(1) & (c)(5) of

    deadlines that are determined to be practicable or, as with other non-
    participating Tribes in an affected transport region, provide for 
    Federal implementation of necessary measures.
        (g) Any provisions of the Act requiring as a condition of program 
    approval the demonstration of criminal enforcement authority or any 
    provisions of the Act providing for the delegation of such criminal 
    enforcement authority. Tribes seeking approval of a Clean Air Act 
    program requiring such demonstration may receive program approval if 
    they meet the requirements for enforcement authority established under 
    Sec. 49.8.

    programs in section 502(d)(1) of the Act.

    502(d)(2)(B) because of failure to submit an operating permit program 
    or EPA disapproval of an operating permit program submittal in whole or 
    part.
        (j) The ``2 years after the date required for submission of such a 
    program under paragraph (1)'' clause in section 502(d)(3) of the Act. 
    The inapplicability of this specific clause does not in any way curtail 
    the general authority delegated to the Administrator under section 
    502(d)(3) to promulgate, administer and enforce a Federal operating 
    permit program for a Tribe not having a program that has been approved 
    in whole.
        (k) Section 502(g), which authorizes a limited interim approval of 
    an operating permit program that substantially meets the requirements 
    of Title V, but is not fully approvable.
        (l) The provisions of section 503(c) that direct permitting 
    authorities to establish a phased schedule assuring that at least one-
    third of the permit applications submitted within the first full year 
    after the effective date of an operating permit program (or a partial 
    or interim program) will be acted on by the permitting authority over a 
    period of not to exceed three years after the effective date.
        (m) The provisions of section 507(a) that specify a deadline for 
    the submittal of plans for establishing a small business stationary 
    source technical and environmental compliance assistance program.
        (n) The provisions of section 507(e) that direct the establishment 
    of a Compliance Advisory Panel.
    
    
    Sec. 49.5  Tribal requests for inapplicability of additional Clean Air 
    Act provisions.
    
        Any Tribe may request that the Administrator specify additional 
    provisions of the Clean Air Act for which it would be inappropriate to 
    treat Tribes in the same manner as States. Such request should clearly 
    identify the provisions at issue and should be accompanied with an 
    explanation why it is inappropriate to treat Tribes in the same manner 
    as States with respect to such provisions.
    
    
    Sec. 49.6  Tribal eligibility requirements.
    
        Sections 301(d)(2) and 302(r), 42 U.S.C. 7601(d)(2) and 7602(r), 
    authorize the Administrator to treat an Indian Tribe in the same manner 
    as a State for the Clean Air Act provisions identified in Sec. 49.3 if

    be exercised in a manner consistent with the terms and purposes of the 
    Clean Air Act and all applicable regulations.

        (i) A map or legal description of the area over which the 
    application asserts authority.
        (ii) A statement by the applicant's legal counsel (or equivalent

    authority (including the nature or subject matter of the asserted 
    regulatory authority) which may include a copy of documents such as 
    Tribal constitutions, by-laws, charters, executive orders, codes, 
    ordinances, and/or resolutions which support the Tribe's assertion of 
    authority.
        (4) A narrative statement describing the capability of the 
    applicant to effectively administer any Clean Air Act program for which 
    the Tribe is seeking approval. The narrative statement must demonstrate

    executive, legislative, and judicial functions of the Tribal 
    government;
        (iv) A description of the existing, or proposed, agency of the 
    Indian Tribe which will assume primary responsibility for administering 
    a Clean Air Act program (including a description of the relationship 
    between the existing or proposed agency and its regulated entities);
        (v) A description of the technical and administrative capabilities 
    of the staff to administer and manage an effective air quality program

    paragraph (a)(4) of this section that the Tribe is reasonably expected 
    to be capable of carrying out the functions to be exercised consistent 
    with Sec. 49.6(a)(4). A Tribe relying on a consortium in this manner 
    must provide reasonable assurances that the Tribe has responsibility 
    for carrying out necessary functions in the event the consortium fails 
    to.
        (6) Where applicable Clean Air Act or implementing regulatory 
    requirements mandate criminal enforcement authority, an application 
    submitted by an Indian Tribe may be approved if it meets the 
    requirements of Sec. 49.8.
        (7) Additional information required by the EPA Regional 
    Administrator which, in the judgment of the EPA Regional Administrator, 
    is necessary to support an application.
        (8) Where the applicant has previously received authorization for a 
    Clean Air Act program or for any other EPA-administered program, the 
    applicant need only identify the prior authorization and provide the 
    required information which has not been submitted in the previous 
    application.
        (b) A Tribe may simultaneously submit a request for an eligibility 
    determination and a request for approval of a Clean Air Act program.
        (c) A request for Clean Air Act program approval must meet any 
    applicable Clean Air Act statutory and regulatory requirements and may 
    contain any reasonable portion of a Clean Air Act program to the extent 
    not inconsistent with applicable statutory and regulatory requirements.
    
    
    Sec. 49.8  Provisions for Tribal criminal enforcement authority.
    
        To the extent that an Indian Tribe is precluded from asserting 
    criminal enforcement authority, the Federal government will exercise 
    primary criminal enforcement responsibility. The Tribe, with the EPA 
    Region, shall develop a procedure by which the Tribal agency will refer 
    potential criminal violations to the EPA Regional Administrator, as 
    agreed to by the parties, in an appropriate and timely manner. This 
    procedure shall encompass all circumstances in which the Tribe is 
    incapable of exercising applicable enforcement requirements as provided 
    in Sec. 49.7(a)(6). This agreement shall be incorporated into a 
    Memorandum of Agreement with the EPA Region.
    
    
    Sec. 49.9  EPA review of Tribal Clean Air Act applications.
    
        (a) The EPA Regional Administrator shall process a request of an 
    Indian Tribe submitted under Sec. 49.7 in a timely manner. The EPA 
    Regional Administrator shall promptly notify the Indian Tribe of 
    receipt of the application.
        (b) Within 30 days of receipt of an Indian Tribe's initial, 
    complete application, the EPA Regional Administrator shall notify all 
    appropriate governmental entities.
        (1) For Tribal applications addressing air resources within the 
    exterior boundaries of the Reservation, EPA's notification of other 
    governmental entities shall specify the geographic boundaries of the 
    Reservation.
        (2) For Tribal applications addressing off-reservation areas, EPA's 
    notification of other governmental entities shall include the substance 
    and bases of the Tribe's assertions that it meets the requirements of 
    Sec. 49.6(a)(3).
        (c) The governmental entities shall have 15 days to provide written 
    comments to EPA's Regional Administrator regarding any dispute 
    concerning the boundary of the Reservation. Where a Tribe has asserted 
    jurisdiction over off-reservation lands, appropriate governmental 
    entities may request a single 15-day extension to the general 15-day 
    comment period.
        (d) In all cases, comments must be timely, limited to the scope of 
    the Tribe's jurisdictional assertion, and clearly explain the 
    substance, bases and extent of any objections. If a Tribe's assertion 
    is subject to a conflicting claim, the EPA Regional Administrator may 
    request additional information and may consult with the Department of 
    the Interior.
        (e) The EPA Regional Administrator shall decide the scope of the 
    Tribe's jurisdiction. If a conflicting claim cannot be promptly 
    resolved, the EPA Regional Administrator may approve that portion of an 
    application addressing all undisputed areas.
        (f) A determination by the EPA Regional Administrator concerning 
    the boundaries of a Reservation or Tribal jurisdiction over other off-
    reservation areas shall apply to all future Clean Air Act applications 
    from that Tribe or Tribal consortia and no further notice of 
    governmental entities as provided in paragraph (b) of this section 
    shall be provided, unless the application presents different 
    jurisdictional issues or significant new factual or legal information 
    relevant to jurisdiction is presented to the EPA Regional 
    Administrator.
        (g) If the EPA Regional Administrator determines that a Tribe meets 
    the requirements of Sec. 49.6, the Indian Tribe is eligible to be 
    treated in the same manner as a State for those Clean Air Act 
    provisions identified in Sec. 49.3. The eligibility will extend to all 
    areas within the exterior boundaries of the Tribe's reservation, as 
    determined by the EPA Regional Administrator, and any other areas the 
    EPA Regional Administrator has determined to be within the Tribe's 
    jurisdiction.
        (h) A Tribal application containing a Clean Air Act program 
    submittal will be reviewed by EPA in the same procedural and 
    substantive manner as EPA would review a similar State submittal.
        (i) The EPA Regional Administrator shall return an incomplete or 
    disapproved application for eligibility or program approval to the 
    Tribe with a summary of the deficiencies.
    
    
    Sec. 49.10  EPA review of State Clean Air Act programs.
    
        A State Clean Air Act program submittal shall not be disapproved 
    because of failure to address air resources within the exterior 
    boundaries of an Indian Reservation or other areas within the 
    jurisdiction of an Indian Tribe.
