    SUMMARY: EPA is proposing to change the regulation that specifies when 
    new and revised State and Tribal water quality standards become 
    effective for Clean Water Act purposes. Under the proposal, new and 
    revised standards adopted after the effective date of the final rule 
    will not be used for Clean Water Act purposes until approved by EPA, 
    unless such new and revised standards are more stringent than the 
    standards previously in effect. The proposal also provides that 
    standards already in effect at the effective date of the new rule may 
    be used for Clean Water Act purposes, whether or not approved by EPA, 
    unless EPA subsequently disapproves them and replaces them with Federal 
    water quality standards.
    
    DATES: EPA must receive comments on this proposed rule on or before 
    August 23, 1999.

    II. Background
    
    A. Statutory
    
    1. The Role of Water Quality Standards Under the CWA
        When the Clean Water Act (CWA or Act) was enacted in 1972, its 
    focus was on the establishment of a system for controlling pollution at 
    the source through imposition of categorical technology-based permit 
    effluent limitations on point sources. However, Congress recognized 
    that such controls would not always be sufficient to meet the goals of 
    the Act, and therefore complemented that technology-based program with 
    the water quality standards program under section 303 of the Act. Under 
    the CWA, water quality standards consist of designated uses for 
    waterbodies, water quality criteria to protect those uses, an 
    antidegradation policy to maintain water quality, and any policies 
    affecting the application and implementation of such standards. Such 
    standards serve both as a description of the desired water quality for 
    particular waterbodies and as a means of ensuring that such quality is 
    attained and maintained.
        The CWA prescribes various uses for water quality standards. For 
    example, they are used as benchmarks for evaluating proposals such as 
    basin grants under section 102(c), plans for the Chesapeake Bay under 
    section 117(b)(2), water quality management planning under section 
    205(j), and contained disposal facilities for dredged spoil under 33 
    U.S.C. 1293(a). Water quality standards are also the basis for 
    identifying impaired waters under sections 303(d)(1)(A) and 304(1) and 
    developing total maximum daily loads (TMDLs) and waste load allocations 
    under section 303(d)(1)(C). Water quality standards are the foundation 
    for water quality-based effluent limitations for NPDES permits under 
    section 301(b)(1)C), serve to limit variances under section 301(h) and 
    (m), and are a floor when permit limitations are relaxed under section 
    402(o)(3). Under section 401, they also serve as a basis for granting 
    or denying State or Tribal certifications for federal licenses or 
    permits for activities that may result in a discharge.
    2. Adoption, Revision, and Review and Approval of State and Tribal 
    Water Quality Standards
        CWA section 303 describes the requirements for adoption, revision, 
    review and approval of water quality standards. Sections 303(a) and (b) 
    provided a transition from the predecessor statute and were designed to 
    ensure that States have water quality
    
    [[Page 37074]]
    
    standards for both interstate and intrastate waters of the United 
    States. Section 303(c) establishes procedures for the periodic review 
    of, and as needed, revisions to States and Tribes' initial standards. 
    Section 303(c) requires States (and hence Tribes which have authorized 
    to be treated in the same manner as States) from time to time but at 
    least once every three years to hold public hearings for the purpose of 
    reviewing applicable water quality standards and, as appropriate, 
    modifying and adopting new or revised standards. The results of such 
    reviews are to be made available to EPA.
        Under section 303(c)(2)(A), whenever a State or authorized Tribe 
    adopts a new or revised standard, the State or Tribe must submit it to 
    EPA. Section 303(c)(3) requires EPA to review such submissions. If the 
    Administrator, within 60 days of such submission, determines that a 
    standard meets the requirements of the Act, ``such standard shall 
    thereafter be the water quality standard for the applicable waters of 
    that State.'' Today's proposed rule addresses the meaning and 
    implementation of the phrase: ``such standard shall thereafter be the 
    water quality standard for the applicable waters of that State.''
        If the Administrator determines that a new or revised standard is 
    not consistent with the requirements of the Act, she shall notify the 
    State or authorized Tribe no later than 90 days after the date of the 
    submission and shall specify the changes needed to meet such 
    requirements. If the State or authorized Tribe does not adopt the 
    necessary changes within 90 days of notification, the Administrator is 
    to promptly propose a federal replacement water quality standard 
    pursuant to section 303(c)(4)(A). In addition, section 303(c)(4)(B) 
    authorizes the Administrator to propose a water quality standard 
    whenever she determines one is necessary, for example, if a State or 
    authorized Tribe fails to update an existing standard or adopt a 
    standard where necessary. Whether proceeding under section 303(c)(4)(A) 
    or (B), the Administrator is to promulgate a final water quality 
    standard not later than 90 days after proposal, unless the State or 
    authorized Tribe has in the meantime taken action that addresses EPA's 
    concern.
    3. CWA Section 510
        As discussed above, the CWA sets out a detailed process to ensure 
    that there will be a complete set of applicable water quality standards 
    available for CWA purposes which meet the minimum requirements of the 
    Act. However, section 510 of the Act also makes it clear that this 
    process was not intended to preempt the right of States to adopt and 
    enforce more stringent standards if they so choose. Thus, if a new or 
    revised standard is more stringent than the otherwise applicable water 
    quality standard, the proposed rule would continue to allow the 
    promulgating State or Tribe to enforce within its boundaries such 
    standards without prior EPA review and approval. Accordingly, the 
    practical consequences of the proposed rule requiring EPA approval 
    before a state water quality standard is considered the ``applicable 
    water quality standard'' are largely confined to new or revised 
    standards which are less stringent than the preceding standards. The 
    interplay between CWA sections 510 and 303 is discussed in more detail 
    in section III.D. below.
    
    B. Regulations
    
        EPA first promulgated a water quality standard regulation in 1975. 
    That regulation specified the minimum requirements for State review and 
    revision of water quality standards, but did not identify the 
    procedures for submitting standards to EPA for review or address 
    whether such standards were effective under the CWA prior to EPA's 
    approval (promulgated Nov. 28, 1975, as 40 CFR 130.17(c), recodified as 
    40 CFR 35.1550).
        In 1983, EPA substantially revised and expanded the water quality 
    standards regulation. This regulation, codified at 40 CFR part 131, 
    specified in more detail the requirements for water quality standards. 
    These revisions included the specific elements that must be in a 
    State's water quality standards, procedures for triennial reviews, and 
    procedures for submitting new or revised standards to EPA. The 
    regulation also for the first time addressed the question of when State 
    standards were effective for purposes of the CWA. Specifically, it 
    provided that ``A State water quality standard remains in effect, even 
    though disapproved by EPA, until the State revises it or EPA 
    promulgates a rule that supersedes the State water quality standard.'' 
    See 40 CFR 131.21(c). As explained in the preamble to the 1983 rule, 
    this provision was based on the view that State water quality standards 
    should be effective under the CWA as soon as they were adopted and 
    effective under State law. In 1991, EPA amended the water quality 
    standards regulation to add procedures by which an Indian Tribe may 
    qualify for the water quality standards and CWA section 401 
    certification programs.
    
    C. The Alaska Litigation
    
        In 1996, a coalition of environmental groups sued EPA, alleging 
    that EPA was violating the CWA by applying new and revised standards 
    adopted by Alaska before EPA had approved the standards (Alaska Clean 
    Water Alliance v. Clark, No. C96-1762R (W.D.Wash.)). On July 8, 1997, 
    the United States District Court for the District of Washington (the 
    Court) issued an opinion in this case holding that, notwithstanding 
    Sec. 131.21(c) of EPA's regulation, the plain meaning of CWA section 
    303(c)(3) was that new or revised State water quality standards did not 
    become effective for CWA purposes until approved by EPA. The parties to 
    the lawsuit have entered into a settlement agreement under with EPA 
    agreed to propose revisions to 40 CFR 131.21(c) consistent with the 
    Court's opinion no later than July 1, 1999, EPA also agreed to take 
    final action within nine months of this proposal. If EPA promulgates a 
    final regulation that substantially conforms to the proposal, 
    plaintiffs have agreed to dismiss their litigation. If the final rule 
    does not substantially conform to the proposal, the plaintiffs retain 
    the right to reactivate the litigation and seek a remedy from the 
    court. Today's proposed rule is issued in accordance with this 
    settlement agreement. EPA seeks comment on both the basic approach and 
    the specific provisions in today's proposal.
    
    III. What Is EPA Proposing and How Will it Work?
    
    A. Summary
    
        This proposed rule makes three principal points. First, today's 
    proposed regulation at Sec. 131.21(c) addresses the issue of when a new 
    or revised State or Tribal water quality standard becomes the 
    ``applicable water quality standard for purposes of the CWA'' in 
    accordance with section 303(c)(3) of the CWA. The proposed rule does 
    not affect the process by which State or Tribal water quality standards 
    are adopted under State or Tribal law, but simply specifies when State 
    or Tribal standards will be recognized as the ``applicable water 
    quality standard'' under the CWA. In accordance with the language of 
    CWA section 303(c)(3) as interpreted by the District Court in the 
    Alaska case, proposed Sec. 131.21(c) provides that new and revised 
    water quality standards adopted after the effective date of the final 
    rule will not become the ``applicable water quality standards for CWA 
    purposes'' until approved by EPA. See proposed Sec. 131.21(c). As 
    discussed above, such ``CWA purposes'' include, but or not limited to, 
    section 303(d)
    
    [[Page 37075]]
    
    listings of impaired waters, development of TMDLs, and establishment of 
    water quality-based effluent limitation in NPDES permits.
        As discussed in more detail below, today's proposed regulation 
    would affect standards adopted after the effective date of EPA's final 
    rule. (In the context of this proposal, the word ``adopted'' refers to 
    completion of the process under which standards are developed and made 
    effective under State and Tribal law.) EPA is proposing the State and 
    Tribal standards adopted prior to that date, which are considered 
    applicable standards under the current federal water quality standards 
    regulation, will remain the applicable standards. This will include 
    those standards that EPA has approved and continue in effect under 
    State and Tribal law as well as those standards in effect under State 
    and Tribal law that EPA has not yet approved or that EPA has 
    disapproved. This ``grandfathering'' of State and Tribal standards 
    adopted and in effect before EPA's new rule becomes affective merely 
    allows such standards to continue in effect; it does not alter EPA's 
    responsibility to complete its review of any standards it has not yet 
    approved or disapproved or to promulgate replacement standards for any 
    disapproved standards.
        Second, today's proposed regulation at Sec. 131.21(c) and (3) state 
    that, after the effect date of the final rule, any changes (i.e, 
    repeals, amendments or additions) to the applicable Sate and Tribal 
    standards must be approved by EPA to be effective for CWA purposes. 
    (This requirement will apply to future changes to ``grandfathered'' 
    standards which automatically become applicable standards under the 
    current rule as well as to changes to future standards which, under the 
    new rule, become applicable standards when approved by EPA.)
        Third, the proposed rule makes it clear that, in accordance with 
    CWA section 510, it does not preempt the right of State or Tribes to 
    adopt and enforce within their boundaries water quality standards which 
    are ``not less stringent'' than the applicable water quality standards. 
    What this means, in practical terms, is that if a State or authorized 
    Tribe adopts a standard which is at least stringent as the applicable 
    standard (either a grandfathered standard or a standard adopted and 
    approved after the effective date of the rule), the State or Tribe may 
    immediately use such a standard for CWA purposes, pursuant to Sec. 510, 
    without waiting for EPA to complete its section 303(c)(3) review. The 
    State may also use standards adopted pursuant to Sec. 510 as a basis 
    for conditions in section 401 certifications for federal permits such 
    as EPA-issued NPDES permits.
        While EPA review of standards adopted pursuant to Sec. 510 is 
    underway, the State or Tribe can repeal or modify them and such changes 
    would go into effect immediately. However, when EPA completes its 
    review and approves such standards, they become the new applicable CWA 
    water quality standards, and subsequent revisions to them will not be 
    applicable for CWA purposes until approved by EPA (subject again to the 
    State's and Tribe's preserved right under section 510 to adopt and 
    enforce an even more stringent standard).
    
    B. Rationale for Changing Sec. 131.21(c)
    
        As mentioned in the background section above, EPA's current 
    regulations at 40 CFR part 131 provide that new and revised State and 
    Tribal standards are effective for CWA purposes as soon as they are 
    effective under State or Tribal law and that they remain in effect, 
    even if subsequently disapproved by EPA, until superseded by a federal 
    promulgation or changed or withdrawn by the State or Tribe. EPA 
    believed such an approach was necessary to avoid an absence of 
    standards prior to EPA approval. See response to comments for 1983 
    regulation, 48 FR 51400, 51412 (Nov. 8, 1983): ``This interpretation is 
    necessary because otherwise there would be no standard at all until 
    federal action was completed.'' Over time, however, it became apparent 
    that this approach did not always serve the purposes of the Act, 
    particularly if a revised standard did not meet the requirements of the 
    Act. The Alaska litigation in which EPA's reliance on existing 
    Sec. 131.21(c) was challenged (see II.C. above) caused EPA to re-
    examine its position.
        EPA believes that the approach set forth in today's proposal not 
    only is consistent with the language of section 303(c)(3) but also 
    addresses the practical concern driving the approach in the 1983 
    regulation. As the Court held, the import of the phrase in section 
    303(c)(3) ``shall thereafter be the water quality standards'' (emphasis 
    added) is that, until the new or revised standards are approved, they 
    are not considered the applicable standards as a matter of federal law. 
    In addition, EPA has re-examined its earlier concern that the 1983 
    approach was necessary to avoid a gap in standards until federal review 
    was complete, because states would repeal their old standard when 
    adopting new or revised one. The fact of the matter is that the repeal 
    of the earlier water quality standard would itself be considered a 
    revision to standards. If, as the words of section 303(c)(3) indicate, 
    revisions need to be approved to be effective for CWA purposes, the 
    repeal of the old standard could not be effective until approved by 
    EPA, and hence there would in fact be no gap in standards.
        Another concern underlying the 1983 regulation was that requiring 
    EPA approval might delay the use of improved water quality standards. 
    However, as a practical matter, only the implementation of less 
    stringent standards would be delayed under today's proposal, since 
    section 510 provides that nothing in the CWA affects the right of 
    States or Tribes to enforce standards within their boundaries that are 
    equally or more stringent than the federally approved water quality 
    standards. Of course, the mere fact that a standard is less stringent 
    than the previous standard does not mean that it is not justified 
    (e.g., new scientific information may show that a less stringent 
    criterion is in fact protective of the designated uses or the previous 
    criterion may have been based on incomplete or inaccurate information). 
    Having EPA review a new or revised standard before it replaces a more 
    stringent standard simply allows EPA to confirm that the new standard 
    is justified and that it meets the requirements of the CWA.
        EPA recognizes that the approach of the proposed rule may change in 
    some respects the relationship between EPA and the States and 
    authorized Tribes. For example, States and authorized Tribes will not 
    be able to base CWA permits on new or revised standards which are less 
    stringent than the predecessor applicable standards unless EPA approves 
    the less stringent standard. On the other hand, there may be less need 
    for federal promulgations to correct deficiencies in State and Tribal 
    standards under the new approach.
    
    C. Options EPA Considered
    
    1. Prospective Effect of the Rule
        Because the Court concluded that the CWA on its face required that 
    new and revised State or Tribal water quality standards be approved by 
    EPA before being used for CWA purposes, EPA considered whether the new 
    rule should govern all standards adopted since 1972, or whether it 
    should apply only to standards adopted after this rulemaking takes 
    effect. For the reasons below, EPA proposes that only new and revised 
    State or Tribal water quality standards adopted after the effective 
    date of this rule must be approved to be the applicable water quality 
    standards for purposes of the CWA. Previously
    
    [[Page 37076]]
    
    adopted standards that are in effect under State and Tribal law on the 
    effective date of this rule will remain applicable standards. If the 
    State or authorized Tribe repeals or revises such standards after the 
    effective date of the rule, any such revisions or repeal would be 
    subject to the new rule, that is, they would need EPA approval to be 
    effective for CWA purposes.
        If EPA were to apply the new interpretation to standards adopted 
    before EPA's final rule, EPA would need to do so consistently. EPA's 
    experience indicates in some cases this would be exceedingly difficult, 
    if not impossible, to do. There are a number of reasons for this. Under 
    the current rule, the approval status of a standard did not affect 
    whether it was the applicable standard for CWA purposes; standards 
    changes have not always been promptly submitted to EPA; and some EPA 
    reviews of standards have not resulted in timely and clear-cut 
    approvals or disapprovals. Confirming in every case that standards 
    currently in effect under State law have been approved by EPA, or, it 
    not, tracking down in each case the last approved predecessor standard, 
    could by a very burdensome task with minimal environmental benefits. 
    For example, if a State or authorized Tribe had reorganized and 
    recodified its water quality standards after approval, it might be 
    difficult today to reconcile the current citations with the citations 
    of the provisions in question when approved. In addition, in the case 
    of standards approved in the 1970's and still in effect, the record of 
    approval could in some instances be difficult to locate, especially in 
    EPA Regional offices where there have been organizational changes and 
    physical relocations of office records over the years. Furthermore, if 
    the last standard which could be clearly demonstrated as approved had 
    later been superseded by other standards a long time ago, it might no 
    longer mesh with the structure of other, approved parts of the State or 
    Tribe's current standards or reflect current science or improved stream 
    conditions. To resurrect such a standard as the applicable standard CWA 
    purposes could in many cases be very artificial, and have uncertain 
    environmental benefits. Finally, the time and effort involved in 
    confirming the status of standards adopted since 1972 would also 
    significantly detract from EPA's ability to make future approval/
    disapproval decisions in a timely manner. For these reasons, EPA 
    believes that there would be extreme practical problems to applying 
    today's proposed approach to all standards adopted since 1972.
        Additionally, changing the status of standards currently on the 
    books could result in confusion, for example, in situations where 
    States or authorized Tribes had in the past relied on the current 
    federal water quality standards regulation to take actions using State 
    or Tribal standards that were not yet approved by EPA. Questions would 
    arise about the need to revisit such State or Tribal actions. While the 
    use of a grandfathering provision excepting such actions from the rule 
    might partially address this problem, EPA believes that it would be 
    difficult to craft, and would not fully eliminate confusion. EPA 
    solicits comment on the approach outlined in today's proposed rule.
    2. Disapproved Water Quality Standards
        As described above, the proposed rule provides that standards 
    adopted by a State or authorized Tribe before the effective date of the 
    rule (and still in effect under State or Tribal law) will remain the 
    applicable water quality standards for CWA purposes regardless of 
    whether they have been approved, disapproved, or simply not yet acted 
    on by EPA. One option EPA considered was to propose that where such a 
    standard was disapproved by EPA, it would cease to be the applicable 
    standard for CWA purposes as of the effective date of the rule or 
    disapproval date, whichever was later. An advantage of such an option 
    would be to limit circumstances under which inadequate standards could 
    be used. A disadvantage is that there would be no standard to replace 
    the disapproved standard until EPA promulgated a superseding federal 
    standard or the State or authorized Tribe revised the disapproved 
    standard and obtain EPA's approval. This gap could theoretically be 
    filled if the proposed rule also provided that the last previously 
    approved standard could be ``resurrected'' until a new standard was 
    approved or promulgated. However, for the reasons given above, tracking 
    down the predecessor standard in each case would be problematic in 
    these instances as well.
        EPA seeks comments on whether the final rule should provide that 
    standards disapproved by EPA prior to the effective date of the final 
    rule should cease to be applicable water quality standards under the 
    CWA. EPA also seeks comments on whether, if it adopts such a provision, 
    the provision should specify that previously approved standards be 
    resurrected and serve as the applicable CWA standard until a 
    replacement for the disapproved standard is adopted by the State or 
    authorized Tribe and approved by EPA, or until EPA promulgates a 
    federal standard.
    
    D. Integration With CWA Section 510
    
        Section 510 of the Act provides that nothing in the Act restricts 
    the right of any State or authorized Tribe (or political subdivision 
    thereof, or interstate agency) to adopt or enforce any standard, as 
    long as it is not less stringent than a standard in effect under the 
    Act. The proposed rule acknowledges this reserved State and Tribal 
    authority by stating explicitly that a State or authorized Tribe may 
    adopt and enforce a water quality standard which is not less stringent 
    than the ``applicable water quality standard'' under the rule. (As 
    explained above, the ``applicable standard'' would be either the 
    standard in effect as of the effective date of the rule, or a 
    superseding approved standard, or a federally promulgated standard.)
        Section 510 is self-implementing. This means that a standard 
    adopted under authority preserved by section 510 may be used 
    immediately to control pollution originating in the State or Tribe 
    adopting the standard, without first obtaining EPA approval or EPA 
    concurrence that the standard is ``not less stringent.'' (Of course, it 
    would be prudent for a State or authorized Tribe to consult with EPA if 
    there is any question about the comparative stringency of a new or 
    revised standard.) Before it is approved by EPA and becomes the 
    ``applicable standard'', such a standard can be changed by the State or 
    authorized Tribe. However, until federally approved, the standard does 
    not have any extra territorial effect. Once such a standard is 
    federally approved, it becomes the new ``applicable standard'' and may 
    serve as the basis for NPDES permit limitations on out-of-state (as 
    well as in-state) sources which could affect the waters covered by the 
    standard. (See CWA sections 402(a)(2), 402(b)(5) and (d)(2); Arkansas 
    v. Oklahoma, 503 U.S. 91 (1992).)
        While the use of standards adopted pursuant to Sec. 510 that have 
    not yet been federally approved and thereby transformed into 
    ``applicable standards for purpose of the Act'' is generally within the 
    State or Tribe's discretion, there is an exception. CWA section 
    301(b)(1)(C), in conjunction with section 402(a), requires that NPDES 
    permits contain limits as needed to meet water quality standards 
    established under authority preserved by section 510, as well as 
    applicable standards established under section 303. Therefore, 
    permitting
    
    [[Page 37077]]
    
    authorities must include effluent limitations in NPDES permits as 
    stringent as necessary to meet all water quality standards of the State 
    or authorized Tribe within which the permittee is discharging, 
    including standards adopted pursuant to 510 that have not yet been 
    approved by EPA.
    
    E. Tracking CWA Standards
    
    1. EPA's CWA WOS Docket
        In today's proposed rule, EPA, is proposing to rely on the adoption 
    date (for existing standards) and the approval status (for future 
    adoptions) to determine whether or not a State or Tribal standard is an 
    ``applicable standard'' under the CWA. To facilitate identifying 
    whether a given State or Tribal standard is an applicable CWA standard, 
    EPA believes it is important to develop a comprehensive tracking 
    system. Under the current regulation, EPA primarily relies on the 
    standards compilations prepared by States and authorized Tribes to 
    determine the applicable CWA standard. For example, where EPA is the 
    NPDES permitting authority, EPA looks to the State's or authorized 
    Tribe's standards, plus any superseding federal standard that may have 
    been promulgated by EPA, as the basis for developing water quality-
    based conditions in a permit. Under today's proposed rule, before using 
    a State or tribal standard, EPA would also need to know whether the 
    standard had been in effect under State and Tribal law on the effective 
    date of the final rule, and, if it had not been, whether EPA had 
    approved the State or Tribal standard (see table at Sec. 131.2 (c) in 
    today's proposed regulation). To simplify the process for determining 
    what the CWA standard is at any given time, EPA is proposing to 
    establish a CWA Water Quality Standards (WQS) docket which would 
    contain the applicable CWA standards for every State, authorized Tribe, 
    and Territory. This CWA WQS docket will contain (1) State and Tribal 
    standards adopted prior to, and still in effect under State or Tribal 
    law on, the effective date of the final rule, (2) State or Tribal 
    standards adopted after the effective date of the final rule and 
    approved by EPA, (3) any applicable federal standards promulgated under 
    subpart D to 40 CFR part 131. This CWA WQS docket will be updated 
    regularly by EPA to reflect future EPA approvals and promulgations. 
    This CWA WQS docket will be available to the public to facilitate the 
    public's ability to determine what the applicable CWA standard is for a 
    particular waterbody.
        In conjunction with today's proposed rule, EPA has established a 
    draft CWA WQS docket for each State, authorized Tribe, and Territory. 
    The draft CWA WQS docket for each State, authorized Tribe, and 
    Territory is located in the corresponding EPA Regional Office. EPA 
    believes the draft CWA WQS docket contains all the current CWA 
    standards in effect as of July 9, 1999. EPA assembled the draft CWA WQS 
    docket with assistance from State, authorized Tribes, and Territories. 
    While we collectively believe it contains all of the elements of each 
    State's or Tribe's program that is subject to review and approval under 
    section 303(c) of the CWA, we will be checking its accuracy before 
    finalizing the rule. Although the docket is not itself a rule but 
    rather an administrative aid, comments from the public pointing out any 
    omissions or erroneous inclusions are welcome. EPA will continue to 
    work with States, authorized Tribes, and Territories to ensure that the 
    CWA WQS docket is current and complete by the time this rule goes into 
    effect.
        EPA believes that, in order for the CWA WQS docket to be useful, it 
    should be in a form that is readily accessible to anyone interested in 
    water quality standards. Establishing hardcopy CWA WQS subdockets in 
    each EPA Regional office EPA's first step in assuring such 
    accessibility. EPA is evaluating long term plans for maintaining the 
    CWA WQS docket, including the possibility of having the CWA WQS docket 
    accessible over the Internet. For example, EPA could establish and 
    maintain a web site where the applicable CWA standard for any State, 
    authorized Tribe, or Territory could be accessed quickly. If this 
    approach is taken, having States and authorized Tribes submit their 
    standards revisions electronically would allow EPA to enter the 
    revisions into an electronic database in a more timely manner. EPA 
    solicits comments on the most effective ways (short term and long term) 
    to make the CWA WQS docket accessible to the public.
        Under the existing regulations at 40 CFR 131.21(d), EPA annually 
    publishes in the Federal Register a notice of State and Tribal 
    standards that have been approved by EPA since the most previous 
    notice. EPA publishes this notice of approvals to keep the public 
    informed of changes in State and Tribal water quality standards 
    program, and to inform the public that EPA has determined such changes 
    are consistent with the CWA. In today's proposed rule, EPA is proposing 
    to delete this annual reporting requirement in light of our plan to 
    establish a CWA WQS docket. See Sec. 131.21(g) in today's proposed 
    rule. EPA does not see the need to maintain this annual notice of 
    approvals, since the CWA WQS docket will allow anyone to review the 
    applicable CWA standard at anytime. EPA believes the establishment of a 
    CWA WQS docket is an improvement over the existing annual reporting 
    requirement because the full text of the standards themselves will be 
    included, not just a listing of the relevant sections, and because it 
    will be updated whenever there is a change to the applicable standards. 
    EPA solicits comment on replacing the exiting annual reporting 
    requirement of State and Tribal approvals with the establishment of a 
    CWA WQS docket.
        As stated above, these draft standards contained in the CWA WQS 
    docket can be viewed in the Regional Offices. Regional contacts, 
    addresses, and phone numbers are listed in the table below.

    2. Approving Standards Promptly
        Section 303(c)(3) of the CWA provides EPA with 60 days to approve, 
    and 90 days to disapprove, water quality standards submitted by States 
    and Tribes. For a variety of reasons, EPA has not always been able to 
    meet these deadlines. Under the current federal water quality standards 
    regulation, delay on the part of EPA in approving State and Tribal 
    revisions to standards has no immediate practical effect, except for 
    the State of Alaska where EPA is already implementing today's proposed 
    changes as a result of the Court's opinion. While the structure of 
    EPA's proposed rule ensures that States and authorized Tribes will not 
    be penalized by past delays, EPA still views the elimination of this 
    backlog as a high priority. EPA headquarters staff are working with EPA 
    Regional Offices, and with States and Tribes, to streamline our 
    approval process and eliminate the backlog.
        EPA is taking several steps to improve the timeliness of its 
    approval/disapproval decisions. For example, EPA is improving 
    coordination among the many EPA offices involved in water quality 
    standards approvals. Although, EPA Regional offices have been delegated 
    the authority to make approval/disapproval decisions, the approval/
    disapproval process involves substantial coordination among several EPA 
    offices. EPA is taking steps to ensure that these offices are providing 
    timely feedback in a coordinated fashion. In addition, EPA is making 
    every effort to communicate to States and Tribes early in the standards 
    revisions process EPA's position with respect to the approvability of 
    specific potential revisions a State or Tribe may be considering. As 
    part of this effort, EPA recently published an updated list of 
    recommended ambient water quality criteria for the protection of human 
    health and aquatic life (see 63 FR 68353) to ensure that States and 
    Tribes have EPA's most current recommendations. In discussions with 
    several States during the development of today's proposal, the States 
    emphasized that in addition to EPA's most current guidance and 
    recommendations, it is necessary to know early in the State regulatory 
    development process whether or not a revision they are considering is 
    inconsistent with the CWA, preferably before the State proposes it for 
    public comment. EPA will continue to discuss with States and Tribes 
    ways to coordinate efforts to improve the standards development 
    process, including ways for EPA to provide input that is both valuable 
    and timely, and for States and Tribes to seek such input.
        Under the Endangered Species Act (ESA), EPA's approval of State and 
    Tribal water quality standards revisions is considered a federal action 
    subject to consultation with the U.S. Fish and Wildlife Service (FWS) 
    and the National Marine Fisheries Service (NMFS) if the standards may 
    affect a federally listed species. Such consultations can in certain 
    cases be time-consuming and delay approval decisions. In recent years, 
    EPA and Services have increased their efforts to achieve greater 
    integration of ESA and CWA Programs. In an effort to coordinate its 
    consultation efforts more efficiently, EPA, the FWS, and NMFS are 
    working at the national level to develop a Memorandum of Agreement 
    (MOA). A draft of the MOA was published in the Federal Register for 
    public comment in January 15, 1999 (see 64 FR 2741). The draft MOA 
    contains procedures for enhancing coordination regarding the protection 
    of endangered and threatened species under section 7 of the Endangered 
    Species Act and the Clean Water Act's Water Quality Standards and 
    National Pollution Discharge Elimination System programs. Among a 
    number of objectives, the draft MOA seeks to make ESA consultations 
    more timely and efficient. Approving/disapproving State and Tribal WQS 
    submissions in the CWA time frames is a priority for EPA. EPA, at both 
    Headquarters and its Regional Offices, is working with a number of 
    States and FWS and NMFS to improve the approval/disapproval process and 
    eliminate frequently encountered delays. Based on the feedback from 
    these discussions, EPA will develop more detailed guidance to achieve 
    the goals discussed above.
    
    IV. Regulatory Flexibility Act as Amended by the Small Business 
    Regulatory Enforcement Fairness Act
    
        Under the Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq., 
    as amended by the Small Business Regulatory Enforcement Fairness Act 
    (SBREFA), federal agencies generally are required to conduct an initial 
    regulatory flexibility analysis (IRFA) describing the impact of the 
    regulatory action on small entities as part of a proposed rulemaking. 
    However, under section 605(b) of the RFA, if the Administrator for the 
    agency certifies that the proposed rule will not have a significant 
    economic impact on a substantial number of small entities, the agency 
    is not required to prepare an IRFA. The Administrator certifies, 
    pursuant to section 605(b) of the RFA, that this proposed rule will not 
    have a significant economic impact on a substantial number of small 
    entities. Therefore, the Agency did not prepare an initial regulatory 
    flexibility analysis.
        The RFA requires analysis of the impacts of a rule on the small 
    entities subject to the rule's requirements. See United States 
    Distribution Companies v. FERC, 88 F.3d 1105, 1170 (D.C. Cir. 1996). 
    Todays' proposed rule establishes no requirements applicable to small 
    entities, and so is not susceptible to regulatory flexibility analysis 
    as prescribed by the RFA. (``[N]o [regulatory flexibility] analysis is 
    necessary when an agency determines that the rule will not have a 
    significant economic impact on a substantial number of small entities 
    that are subject to the requirements of the rule,'' United Distribution 
    at 1170, quoting Mid-Tex Elec. Co-op v. FERC, 773 F.2d 327, 342 (D.C. 
    Cir. 1985) (emphasis added by United Distribution court).) Today's 
    proposed rule, once finalized, will only have a direct effect on States 
    and authorized Tribes, which by definition are not small entities under 
    the RFA. The Agency is thus certifying that today's proposed rule will 
    not have a significant economic impact on substantial number of small 
    entities, within the meaning of the RFA.
    
    [[Page 37079]]
    
    V. Unfunded Mandates Reform Act
    
        Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), P.L. 
    104-4, establishes requirements for Federal agencies to assess the 
    effects of their regulatory actions on State, local, and tribal 
    governments and the private sector. Under section 202 of the UMRA, EPA 
    generally must prepare a written statement, including a cost-benefit 
    analysis, for proposed and final rules with ``Federal mandates'' that 
    may result in expenditures to State, local, and tribal governments, in 
    the aggregate, or the private sector, $100 million or more in any one 
    year. Before promulgating an EPA rule for which a written statement is 
    needed, section 205 of the UMRA generally requires EPA to identify and 
    consider a reasonable number of regulatory alternatives and adopt the 
    least costly, most cost-effective or least burdensome alternative that 
    achieves the objectives of the rule. The provisions of section 205 do 
    not apply when they are inconsistent with applicable law. Moreover, 
    section 205 allows EPA to adopt an alternative other than the least 
    costly, most cost-effective or least burdensome alternative if the 
    Administrator publishes with the final rule an explanation why they 
    alternative was not adopted. Before EPA establishes any regulatory 
    requirements that may significantly or uniquely affect small 
    governments, including tribal governments, it must have developed under 
    section 203 of the UMRA a small government agency plan. The plan must 
    provide for notifying potentially affected small governments, enabling 
    officials of affected small governments to have meaningful and timely 
    input in the development of EPA regulatory proposals with significant 
    Federal intergovernmental mandates, and informing, educating, and 
    advising small governments on compliance with the regulatory 
    requirements.
        Today's proposed rule contains no Federal mandates (under the 
    regulatory provisions of Title II of the UMRA) for State, local, or 
    tribal governments or the private sector. The proposed rule does not 
    affect the process by which State or Tribal water quality standards are 
    adopted under State or Tribal law, but simply specifies when a State or 
    Tribal adoption will be recognized as the applicable water quality 
    standard for general CWA purposes. The rule imposes no enforceable duty 
    on any State, local or Tribal governments or the private sector. This, 
    today's rule is not subject to the requirements of section 202 and 205 
    of the UMRA.
        EPA has determined that this rule contains no regulatory 
    requirements that might significantly or uniquely affect small 
    governments. EPA's proposed rule will only address a single 
    administrative aspect of the water quality standards approval process 
    (i.e. the timing of the ``effectiveness'' of State or Tribal standards 
    under the CWA.) There will be no revisions to existing submission 
    requirements and no revisions to EPA's standard for review. Thus, this 
    proposed rule is not subject to the requirements of section 203 of 
    UMRA.
    
    VI. Regulatory Planning and Review, Executive Order 12866
    
        Under Executive Order 12866, (58 FR 51735 (October 4, 1993)) the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to OMB review and the requirements of the 
    Executive Order. The Order defines ``significant regulatory action'' as 
    one 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 government 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 
    the Executive Order.''
        It has been determined that this rule is not a ``significant 
    regulatory action'' under the terms of Executive Order 12866 and is 
    therefore not subject to OMB review.
    
    VII. Enhancing the Intergovernmental Partnership, Executive Order 
    12875
    
        Under Executive Order 12875, EPA may not issue a regulation that is 
    not required by statute and that creates a mandate upon a state, local 
    or tribal government, unless the Federal government provides the funds 
    necessary to pay the direct compliance costs incurred by those 
    governments, or EPA consults with those governments. If EPA complies by 
    consulting, Executive Order 12875 requires EPA to provide to the Office 
    of Management and Budget a description of the extent of EPA's prior 
    consultation with representatives of affected State, local and tribal 
    governments, the nature of their concerns, any written communications 
    from the governments, and a statement supporting the need to issue the 
    regulation. In addition, Executive Order 12875 requires EPA to develop 
    an effective process permitting elected officials and other 
    representatives of State, local and tribal governments ``to provide 
    meaningful and timely input in the development of regulatory proposals 
    containing significant unfunded mandates.''
        Today's proposed rule does not create a mandate on State, local or 
    trial governments. The proposed rule does not impose any enforceable 
    duties on these entities. Today's proposed rule, once finalized, will 
    only address a single administrative aspect of the water quality 
    standards approval process (i.e., the timing of the ``effectiveness'' 
    of State or Tribal standards under the CWA). There will be no revisions 
    to existing submission requirements and no revisions to EPA's standards 
    for review. Accordingly, the requirements of section 1(a) of Executive 
    Order 12875 do not apply to this rule.
    
    VIII. Consultation and Coordination With Indian Tribal Governments, 
    Executive Order 13084
    
        Under Executive Order 13084, EPA may not issue a regulation that is 
    not required by statute, that significantly or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by the tribal governments, or EPA consults with those 
    governments. If EPA complies by consulting, Executive Order 13084 
    requires EPA to provide to the Office of Management and Budget, in a 
    separately identified section of the preamble to the rule, a 
    description of the extent of EPA's prior consultation with 
    representatives of affected tribal governments, a summary of the nature 
    of their concerns, and a statement supporting the need to issue the 
    regulation. In addition, Executive Order 13084 requires EPA to develop 
    an effective process permitting elected officials and other 
    representatives of Indian tribal governments ``to provide meaningful 
    and timely input in the development of regulatory policies on matters 
    that significantly or uniquely affect their communities.''
        Today's proposed rule does not significantly or uniquely affect the 
    communities of Indian tribal governments, nor does it impose 
    substantial direct compliance costs on them. Today's proposed rule, 
    once finalized, will only address a single administrative aspect of the 
    WQS

    approval process (i.e., the timing of the ``effectiveness'' of Tribal 
    WQS under the CWA). There will be no revisions to existing submission 
    requirements and no revisions to EPA's standards for review. 
    Accordingly, the requirements of section 3(b) of Executive Order 13084 
    do not apply to this rule.
    
    IX. Paperwork Reduction Act
    
        This action requires no new information collection activities 
    subject to the Paperwork Reduction Act (44 U.S.C. 3501 et seq.). 
    Therefore, no Information Collection Request will be submitted to the 
    Office of Management and Budget for review in compliance with the 
    Paperwork Reduction Act.
    
    X. Protection of Children From Environmental Health Risks and 
    Safety Risks, Executive Order 13045
    
        Executive Order 13045: ``Protection of Children from Environmental 
    Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
    to any rule that: (1) is determined to be ``economically significant'' 
    as defined under E.O. 12866, and (2) concerns an environmental health 
    or safety risk that EPA has reason to believe may have a 
    disproportionate effect on children. If the regulatory action meets 
    both criteria, the Agency must evaluate the environmental health or 
    safety effects of the planned rule on children, and explain why the 
    planned regulation is preferable to other potentially effective and 
    reasonably feasible alternatives considered by the Agency. EPA 
    interprets E.O. 13045 as applying only to those regulatory actions that 
    are based on health or safety risks, such that the analysis required 
    under section 5-501 of the Order has the potential to influence the 
    regulation. This proposed rule is not subject to E.O. 13045 because it 
    is not economically significant as defined under E.O. 12866 and, 
    further, it does not establish an environmental standard intended to 
    mitigate health or safety risks.
    
    XI. National Technology Transfer and Advancement Act
    
        Section 12(d) of the National Technology Transfer and Advancement 
    Act of 1995 (``NTTAA''), Pub. L. No. 104-113, section 12(d)( (15 U.S.C. 
    272 note) directs EPA to use voluntary consensus standards in it 
    regulatory activities unless to do so would be inconsistent with 
    applicable law or otherwise impractical. Voluntary consensus standards 
    are technical standards (e.g., materials specifications, test methods, 
    sampling procedures, and business practices) that are developed or 
    adopted by voluntary consensus standards bodies. The NTTAA directs EPA 
    to provide Congress, through OMB, explanations when the Agency decides 
    not to use available and applicable voluntary consensus standards.
        This proposed rulemaking does not involve technical standards. 
    Therefore, EPA is not considering the use of any voluntary consensus 
    standards. EPA welcomes comments on this aspect of the proposed 
    rulemaking, and specifically invites the public to identify potentially 
    applicable voluntary consensus standards and to explain why such 
    standards should be used in this regulation.

        (c) How do I determine which water quality standards are applicable 
    for purposes of the Act?
        You may determine which water quality standards are applicable 
    water quality standards for purposes of the Act for the following 
    table:
    
    ----------------------------------------------------------------------------------------------------------------
                      If                             Then                    Unless               In which case

    ----------------------------------------------------------------------------------------------------------------
    
        (d) When do I use the applicable water quality standards identified 
    in paragraph (c) of this section?
        Applicable water quality standards for purposes of the Clean Water 
    Act (CWA) are the minimum standards which must be used when the CWA and 
    regulations implementing the CWA refer to water quality standards, for 
    example, in identifying impaired waters and calculating TMDLs under 
    section 303(d), developing NPDES permit limitations under section 
    301(b)(1)(C), evaluating proposed discharges or dredged or fill 
    material under section 404, and in issuing certifications under section 
    401 of the Act.
        (e) For how long does the applicable water quality standard for 
    purposes of the Act remain the applicable water quality standards for 
    purposes of the Act?
        A State or Tribe's applicable water quality standards for purposes 
    of the Act remains in effect until EPA approves a change, deletion, or 
    addition to that water quality standard, or until EPA promulgates a 
    more stringent water quality standard.
        (f) Can standards other than those identified in paragraph (c) of 
    this section be used for purposes of the Act?
        State or Tribal water quality standards which are not less 
    stringent than the applicable water quality standards may be adopted 
    and enforced within the boundaries of the adopting State or authorized 
    Tribe.
        (g) How can I find out what the applicable standards are for 
    purposes of the Act?
    
    [[Page 37081]]
    
        EPA will maintain a docket system, available to the public, 
    identifying the applicable water quality standards for purposes of the 
    Act.
