    -----------------------------------------------------------------------
    
    SUMMARY: EPA is determining, pursuant to its federal planning authority 
    in Clean Air Act (CAA) section 110(c), that the Phoenix, Arizona ozone 
    nonattainment area has in place sufficient control measures to meet the 
    15 percent rate of progress (ROP) requirement in Clean Air Act (CAA) 
    section 182(b)(2). EPA is also approving, under CAA sections 110(k) and 
    182(a)(1), the 1990 base year emissions inventory for the Phoenix 
    metropolitan area that was submitted to EPA by the State of Arizona on 
    April 1, 1993.
    
    EFFECTIVE DATE: June 26, 1998.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
    A. Clean Air Act Requirements
    
        The Phoenix metropolitan area was originally classified as a 
    moderate ozone nonattainment area on November 6, 1991.1 
    Section 182(b) of the Clean Air Act (CAA or Act) requires that each 
    state in which all or part of a moderate ozone nonattainment area is 
    located submit, by November 15, 1992, an inventory of actual emissions 
    from all sources, as described in sections 172(c)(3) and 182(a)(1), in 
    accordance with guidance provided by the Administrator. Section 
    182(b)(1)(A) of the CAA also requires states with moderate and above 
    ozone nonattainment areas to develop plans to reduce volatile organic 
    compounds (VOC) emissions by 15 percent, net of growth, from the 1990 
    baseline. The 15 percent rate of progress (ROP) plans were to be 
    submitted by November 15, 1993, and the reductions were required to be 
    achieved by November 15, 1996.
    ---------------------------------------------------------------------------
    
        \1\ The Phoenix metropolitan area was recently reclassified from 
    moderate to serious for ozone. 62 FR 60001 (November 6, 1997). 
    Today's action relates to the moderate area CAA requirements for a 
    1990 base year inventory and a 15 percent ROP demonstration. The 
    reclassification does not affect the area's continuing obligation to 
    meet these requirements.
    ---------------------------------------------------------------------------
    
        Although the November 15, 1996 deadline has now passed, the 15 
    percent ROP requirement remains. Once a statutory deadline has passed 
    and has not been replaced by a later one, the deadline then becomes 
    ``as soon as possible.'' Delaney v. EPA, 898 F.2d 687, 691 (9th Cir. 
    1990). EPA has interpreted this requirement to be ``as soon as 
    practicable.'' See the proposed rule for this final action at 63 FR 
    3687 (January 26, 1998).2 This requirement is discussed 
    further in section II below.
    ---------------------------------------------------------------------------
    
        \2\ The reader should consult this proposed rule for a more 
    detailed discussion of the CAA requirements applicable to today's 
    final action, the State's 15 percent ROP plans and EPA's evaluation 
    of them, and EPA's proposed 15 percent demonstration.
    ---------------------------------------------------------------------------
    
    B. Phoenix's 15 Percent Plan
    
        The State of Arizona submitted its initial 15 percent rate of 
    progress plan for the metropolitan Phoenix area on November 15, 1993 
    and supplemented it on April 8, 1994. On April 13, 1994 EPA found the 
    initial plan incomplete because it failed to include, in fully adopted 
    and enforceable form, all of the measures relied upon in the 15 percent 
    demonstration. This incompleteness finding started the 18-month 
    sanction ``clock'' in CAA section 179 and the two-year clock under 
    section 110(c) for EPA to promulgate a federal implementation plan 
    (FIP) covering the 15 percent ROP requirement. Subsequently, in 
    November 1994 and April 1995, Arizona submitted an attainment plan for 
    the Phoenix area which updated the 15 percent ROP demonstrations.
        On May 12, 1995, EPA found the revised 15 percent plan and the 
    attainment plan complete, turning off the sanctions clock; however, 
    under section 110(c), the FIP clock continues until EPA approves the 15 
    percent plan. Since 1995, EPA has acted to approve many of the control 
    measures relied upon in this plan but has not yet acted on the overall 
    15 percent plan.
        The 15 percent ROP demonstration in the State's plan relied 
    primarily on improvements to the State's vehicle emissions inspection 
    and maintenance (I/M) program. Not all the emission reductions 
    attributed to the program have been realized because of technical 
    problems with implementing certain parts of the I/M program. In part to 
    replace these lost emission reductions
    
    [[Page 28899]]
    
    and in part to ensure continued progress toward attainment of the ozone 
    standard in the Phoenix area, the State opted into EPA's federal 
    reformulated gasoline (RFG) program in 1997 (60 FR 30260 (June 3, 
    1997)) and EPA recently approved the State's own, more stringent 
    Cleaner Burning Gasoline (CBG) program which is intended to replace the 
    federal program. 63 FR 6653 (February 10, 1998).
    
    C. EPA's 15 Percent ROP Plan
    
        In August 1996, EPA was sued by the American Lung Association of 
    Arizona and others, American Lung Association of Arizona, Inc. et al. 
    v. Browner, No. CIV 96-1856 PHX ROS (D. Ariz.) to enforce EPA's 
    obligation under CAA section 110(c) to promulgate a federal plan for 
    the 15 percent ROP requirement. On July 8, 1997 a consent decree was 
    filed in the case establishing a schedule of January 20, 1998 for 
    proposing and May 18, 1998 for promulgating a 15 percent ROP plan. 
    EPA's obligation to promulgate a federal plan is relieved to the extent 
    that it has approved State measures.
        The State's 15 percent plan as revised and submitted in 1993 
    through 1995 does not reflect the changes to the control strategy 
    necessitated by the problems with the enhanced I/M program and the 
    implementation of the federal RFG program, nor does it include the 
    recalculation of the target emission level that EPA guidance requires 
    if post-1996 emissions reductions (such as those from the RFG program) 
    are to be credited to the 15 percent plan. As a result, EPA has not 
    received a complete state submittal containing a revised 15 percent ROP 
    demonstration that it could act on without additional analysis, public 
    hearing and adoption by the State. Thus, EPA is complying with the ALAA 
    consent decree today by promulgating, pursuant to its CAA section 
    110(c) FIP authority, a federal 15 percent ROP plan for the Phoenix 
    area.
    
    D. Proposed Action
    
        On January 26, 1998 (63 FR 3687), EPA proposed to determine that 
    the Phoenix area will have sufficient controls in place by no later 
    than April 1, 1999 to meet the 15 percent rate of progress requirement 
    and that this date is the most expeditious date practicable for 
    achieving the 15 percent target, based on the set of controls EPA has 
    proposed for crediting in the 15 percent demonstration and the 
    unavailability of any other practicable controls that could advance the 
    date. The technical basis for this determination and the list of 
    control measures that provide the required 15 percent VOC reduction are 
    summarized in the proposal and are fully documented in the technical 
    support document (TSD) that accompanies this rulemaking.
        EPA also proposed to approve the 1990 base year emissions inventory 
    for the Phoenix metropolitan area that was submitted to EPA by the 
    State of Arizona on April 1, 1993. EPA's review of this inventory is 
    also summarized in the proposal and fully documented in the TSD.
    
    II. Public Comment and EPA Responses
    
        EPA received only one set of comments on its proposed determination 
    that the Phoenix, Arizona ozone nonattainment area has in place 
    sufficient control measures to meet the 15 percent ROP requirement in 
    CAA section 182(b)(2). These comments were submitted by the Arizona 
    Center for Law in the Public Interest (ACLPI) on behalf of the 
    plaintiffs in ALAA.
        EPA has responded to most significant comments below and has 
    provided full responses to all comments in the TSD that accompanies 
    this rulemaking.
        Comment: ACLPI claims that EPA's proposal is flawed because it does 
    not propose FIP measures as an alternative to approving a State 15 
    percent plan, and without such an alternative proposal, EPA's decision 
    making process here will be inherently biased, unfair and violative of 
    the Administrative Procedures Act. ACLPI states that the only way to 
    negate this bias and prejudgment is for EPA to immediately propose a 
    FIP, so that it has an alternative to approval of the State's 
    demonstration.
        Response: This comment, as well as others discussed below, reflects 
    a basic misapprehension of the nature of EPA's January 26, 1998 
    proposal. Contrary to ACLPI's claims, EPA did not propose to approve or 
    otherwise act on Arizona's 15 percent SIP. Rather, the Agency proposed 
    a 15 percent ROP FIP under its federal planning authority in CAA 
    section 110(c).3
    ---------------------------------------------------------------------------
    
        \3\ EPA did at the same time propose to approve under CAA 
    section 110(k) the State's 1990 Base Year Emission Inventory. This 
    inventory was required by CAA section 182(a)(1) and was submitted 
    separately from the 15 percent plan. See 63 FR 3688.
    ---------------------------------------------------------------------------
    
        Nowhere in the proposal did EPA state or otherwise indicate that it 
    was proposing to approve the State's 15 percent plan. In fact, in the 
    section discussing its FIP obligation under ALAA, EPA concluded that it 
    did ``not have in front of it a complete state submittal containing a 
    revised 15 percent ROP demonstration that it could act on without 
    additional analysis, public hearing and adoption by the State.'' 
    Emphasis added. 63 FR 3688. In the conclusion section of the proposal, 
    EPA stated that it was acting pursuant to its CAA section 110(c) 
    authority in proposing a determination that the Phoenix metropolitan 
    area has in place sufficient control measures to meet the 15 percent 
    ROP requirement. See 63 FR 3692. CAA section 110(c) provides EPA's 
    authority to promulgate FIPs. In contrast, EPA's SIP approval authority 
    resides in section 110(k).
        The proposed FIP consists of a federal demonstration that already-
    approved State and federal control measures, combined with already-
    proposed federal measures, are sufficient to provide for a 15 percent 
    ROP in the Phoenix area as required by CAA section 182(b)(1)(A)(i) and 
    that there are no other measures which would meaningfully advance the 
    date by which the 15 percent ROP will be met. See 63 FR 3692. As a 
    consequence of this finding, EPA did not, and was not required to, 
    propose any additional federal measures.
        EPA notes that this is not the first time it has promulgated an 
    Arizona FIP that consists only of a demonstration that existing State 
    and federal measures were adequate. In 1991, EPA promulgated attainment 
    and maintenance demonstrations for the Pima County (Tucson), Arizona 
    carbon monoxide (CO) nonattainment area that consisted solely of a 
    demonstration that existing approved State and federal measures were 
    adequate for expeditious attainment and long-term maintenance of the CO 
    standard in the area and that no additional federal measures were 
    necessary. See 56 FR 5458, 5470 (February 11, 1991).
        Comment: ACLPI asserts that if EPA found that the State has not 
    submitted a complete 15 percent ROP demonstration, it should have 
    disapproved it on that basis instead of proceeding to supply its own 
    data and analysis to produce a showing on the State's behalf, an 
    approach which conflicts with the Act. ACLPI states that EPA's 
    statutory duty is to approve or disapprove what the state submits and 
    that EPA cannot write a plan and pretend it is the State's. Finally, 
    ACLPI states that Arizona has had more than ample time to submit its 15 
    percent plan and if the State's demonstration is inadequate, then EPA 
    must disapprove it and adopt a FIP.
        Response: As discussed above, EPA proposed a 15 percent ROP 
    demonstration under its federal planning authority in CAA section 
    110(c) and did not propose any action on Arizona's 15 percent SIP. When
    
    [[Page 28900]]
    
    acting in place of the State pursuant to a FIP under section 110(c), 
    EPA ``stands in the shoes of the defaulting State, and all the rights 
    and duties that would otherwise fall to the State accrue instead to 
    EPA.'' Central Arizona Water Conservation District v. EPA, 990 F.2d 
    1531, 1541 (9th Cir. 1993). Thus, in preparing this FIP demonstration, 
    it is EPA's responsibility to supply its own data and analyses of that 
    data and to produce the required showing that would otherwise be the 
    responsibility of the State. Thus, the approach EPA took in this 
    rulemaking is fully consistent with the Act.
        EPA did base its proposed determination in part on a reanalysis of 
    the State's plan. This approach is reasonable given that the State had 
    already prepared an extensive and competent technical evaluation of 
    emission sources in the Phoenix area and the effect of controls on 
    reducing emissions from those sources. In preparing its own 
    demonstration, EPA did modify some of the information in the State's 
    plan to reflect the actual implementation status of the State's I/M 
    program and the implementation of new federal and state controls. 
    However, a federal plan based on technical information contained in a 
    State plan does not constitute or imply approval of that State plan.
        Since no action was proposed in regard to the State's 15 percent 
    ROP plan, comments relating to the appropriate disposition of that plan 
    are not relevant to this rulemaking. EPA notes that it is not required 
    in this instance to disapprove the State plan prior to promulgating a 
    replacement FIP under CAA section 110(c).
        EPA acknowledges that it is required by the Act to take action on 
    submitted SIPs. However, at this time inaction on the State's 15 
    percent plan in no way affects EPA's promulgation of this FIP.
        Comment: ACLPI comments that EPA is extending until April 1, 1999 
    the time for achieving the 15 percent reduction that was supposed to 
    have been achieved by November 15, 1996 and has justified this lengthy 
    extension by adopting several policies that ACLPI asserts are not 
    consistent with applicable case law or the Clean Air Act.
        First, ACLPI states that although it agrees with EPA that Delaney 
    v. EPA, 898 F.2d 687, 691 (9th Cir. 1990) supplies the relevant test 
    for compliance once a statutory deadline has passed, it disagrees with 
    the Agency's interpretation that under the Delaney case, the 
    appropriate standard is ``as soon as practicable.'' ACLPI notes that 
    the actual phrase used by the Delaney court was ``as soon as 
    possible,'' using every available control measure and asserts that the 
    difference between ``practicable'' and ``possible'' is not merely 
    semantic. According to ACLPI, ``practicability,'' as used in the Act, 
    allows for consideration of various economic and social factors in 
    determining the required speed of progress. ACLPI believes that to say 
    that the pace for compliance after the Clean Air Act deadline has 
    passed is still as soon as ``practicable'' is to read the deadline out 
    of the statute which is why the Delaney court allegedly set a much more 
    stringent test--compliance as soon as possible--for areas that miss a 
    statutory deadline.
        Response: In Delaney, the Ninth Circuit interpreted the Clean Air 
    Act requirement for EPA to develop a CO federal implementation 
    attainment plan for two Arizona areas after the passage of the then 
    applicable statutory attainment date of December 31, 1987. The Court 
    concluded that after the passage of that date, ``the national ambient 
    air quality standards must be attained as soon as possible with every 
    available measure * * *.'' 898 F.2d at 691. The Delaney Court arrived 
    at this test by relying on a statement in an EPA guidance document 
    providing that if a state plan's ``control measures are not adequate to 
    demonstrate attainment by 1987, additional measures which can be 
    implemented after 1987 must be identified and adopted and attainment 
    must be demonstrated by the earliest possible date * * *. 46 Fed. Reg. 
    7186 (January 22, 1981).'' 4 In another part of the opinion 
    concerning reasonably available control measures, the Court noted 
    another EPA guidance document specifying that a control measure would 
    be deemed not reasonably available if it would not advance attainment, 
    would cause substantial widespread and long-term adverse impact, or 
    would take too long to implement. 898 F.2d at 692.
    ---------------------------------------------------------------------------
    
        \4\ Following the Delaney opinion, EPA revoked certain portions 
    of this guidance document in order to clarify that the Agency did 
    not intend to require post-1987 plans to include every conceivable 
    control measure. 55 FR 38326 (September 18, 1990).
    ---------------------------------------------------------------------------
    
        EPA believes that the appropriate interpretation of Delaney's ``as 
    soon as possible'' test is informed by the Court's acknowledgment of 
    certain limitations on the speed of compliance as expressed in its 
    citation of the guidance related to the scope of reasonably available 
    measures. Therefore, consistently since the Ninth Circuit's opinion, 
    EPA has framed the ``as soon as possible'' Delaney test, in the post-
    statutory attainment deadline context, to mean `` `as expeditiously as 
    practicable,' by a fixed date,'' and has stated that ``[t]he statute 
    does not require measures that are absurd, unenforceable, or 
    impracticable.'' 55 FR 36458, 36505 (Sept. 5, 1990).5 In 
    addition to applying this interpretation of the Delaney test to 
    attainment plans after the passage of the statutory attainment 
    deadline, the Agency has also consistently applied it in its actions on 
    plans that address the 15 percent requirement following the November 
    15, 1996 statutory deadline for these plans. See, e.g., 62 FR 31343, 
    31345-31346 (June 9, 1997) approving the 15 percent ROP SIP for 
    Philadelphia; 62 FR 33999, 34000-34001 (June 24, 1997) approving the 15 
    percent ROP SIP for the northern Virginia.
    ---------------------------------------------------------------------------
    
        \5\ In its proposal of an attainment CO FIP for Arizona, EPA 
    restated its interpretation of the Delaney test as requiring ``a 
    demonstration of attainment as expeditiously as practicable 
    utilizing all measures available to the federal government that are 
    capable of advancing the attainment date, short of those producing 
    absurd results, such as severe socioeconomic disruptions.'' 55 FR 
    41204, 41210 (October 10, 1990).
    ---------------------------------------------------------------------------
    
        Moreover, EPA notes that one court, while finding Delaney not 
    precisely on point for its purpose of fashioning a remedy in a 
    citizen's enforcement action, nevertheless made some instructive 
    observations on the relationship between the two standards. The Court 
    noted that:
    
        although the Delaney opinion utilized the `as soon as possible' 
    standard employed by EPA guidelines, it did not do so out of 
    rejection of the `practicable' standard or out of concern that the 
    two standards differed. Rather it simply had no occasion to compare 
    them. Indeed the Delaney court appeared to blur them when it 
    criticized Arizona for rejecting measures without demonstrating that 
    such measures were `impracticable' or unreasonable.
    
    Citizens for a Better Environment v. Deukmejian, 746 F. Supp. 976, 985 
    (N.D. Cal. 1990). The Court went on to observe that:
    
        [a]s a practical matter, however, no Court will use its 
    equitable powers to impose remedies that are irrational, albeit 
    ``possible.'' Thus as long as time is considered paramount, and the 
    term ``practical'' is strictly construed in keeping with the 
    purposes of the Act, the ``as expeditiously as practicable'' 
    standard should yield no less results than an ``as soon as 
    possible'' standard.
    
    The Court concluded that ``when properly interpreted, there is no 
    practical difference between the two standards.'' Id. EPA agrees with 
    this assessment.
        Furthermore, while EPA believes that it is consistent with the 
    Delaney test to take into account socioeconomic factors as described 
    above, the issue is effectively moot with regard to this
    
    [[Page 28901]]
    
    rulemaking. In proposing, for the purposes of its 15 percent 
    demonstration, that ``as soon as practicable'' is April 1, 1999, the 
    Agency did not consider any economic or social factors. Rather the 
    factors EPA considered were the Agency's authority and resources to 
    implement a measure, whether the measure provided a significant 
    emission reduction, and whether the measure could be implemented soon 
    enough to meaningfully advance the date by which the 15 percent 
    reduction could be demonstrated. The Agency believes, as discussed 
    above and in response to an additional comment below, that the 
    consideration of these factors is entirely appropriate and consistent 
    with both the Clean Air Act and the Delaney opinion.
        Comment: ACLPI comments that in its proposed action, EPA asserted 
    that the 15 percent ROP need not be achieved until April 1, 1999 
    because (a) that is the soonest such reductions will be achieved under 
    the State's adopted programs and various adopted and proposed EPA 
    programs and (b) no other measures are available that would reduce VOC 
    emissions by more than 0.5 percent or advance achievement of the 15 
    percent ROP by three or more months. ACLPI asserts that there is 
    nothing in the Clean Air Act or Delaney that allows de minimis 
    exemptions for percent reductions or months of delay.
        Response: The inherent authority of administrative agencies to 
    exempt de minimis situations from a statutory requirement has been 
    upheld in contexts where an agency is invoking a de minimis exemption 
    as ``a tool to be used in implementing the legislative design when 
    ``the burdens of regulation yield a gain of trivial or no value.'' 
    Alabama Power Co. v. Costle, 636 F.2d 323, 360-61 (D.C. Cir. 1979).
        In this rulemaking, EPA has invoked this de minimis doctrine for 
    gauging when the promulgation of a new control would or would not 
    contribute to meeting the statutory requirement for a 15 percent ROP in 
    the Phoenix area as soon as is practicable. EPA has interpreted the 
    ``as soon as practicable'' test to require a showing that the 
    applicable implementation plan contains all VOC control measures that 
    are practicable for the area and that meaningfully accelerate the date 
    by which the 15 percent level is achieved. Measures that provide only 
    an insignificant additional amount of reductions or could not be 
    implemented soon enough to meaningfully advance the date by which the 
    15 percent is demonstrated are not required to be implemented. See 
    Memorandum, John S. Seitz, Director of the Office of Air Quality 
    Planning and Standards, and Richard B. Ossias, Deputy Associate General 
    Counsel to Regional Air Division Directors; ``15 Percent VOC SIP 
    Approvals and the `As Soon As Practicable' Test;'' February 12, 1997.
        For determining whether additional measures were necessary for this 
    demonstration, EPA proposed to define ``significant emission 
    reduction'' to be equal to or more than one-half of one percent (0.5 
    percent) of the total emission reductions needed to meet the 15 percent 
    ROP requirement in 1999 for the Phoenix nonattainment area, the 
    equivalent of 0.5 metric tons per day (mtpd). Thus any measures that 
    would result in less than a 0.5 mtpd reduction by April 1, 1999 were 
    considered to yield de minimis reductions and were rejected from 
    further review.
        In the context of this rulemaking where the 15 percent ROP will be 
    achieved within one year, 0.5 mtpd is truly de minimis, representing 
    one two-hundredths of the emission reductions needed to show the 15 
    percent ROP. In terms of control requirements, more than 200 of these 
    ``de minimis'' measures would be needed to demonstrate 15 percent ROP 
    in Phoenix. The federal imposition of a measure or group of measures 
    with so little impact on the ROP demonstration would be nonsensical. 
    Thus a regulation imposing one of these de minimis measures would 
    indeed yield ``a gain of trivial or no value.'' As such, a de minimis 
    exemption is an entirely ``appropriate tool to be used in implementing 
    the legislative design'' of the CAA's rate of progress and general FIP 
    requirements. Alabama Power at 360.
        EPA proposed to define ``meaningfully accelerate the date by which 
    the 15 percent is demonstrated'' as three or more months. EPA has 
    projected that the 15 percent ROP will be demonstrated in the Phoenix 
    area by April 1, 1999. Therefore, if a measure could advance that 
    demonstration date to on or before January 1, 1999, then EPA would 
    consider that the measure meaningfully accelerated the 15 percent ROP. 
    In the proposal, EPA explained its selection of three months as a 
    balance between the environmental benefit of advancing the date and the 
    potential to trivialize the ``as soon as practicable'' demonstration. 
    63 FR 3687, 3691.
        The 15 percent ROP progress requirement is part of the Act's 
    overall scheme for ozone attainment. In Phoenix, ozone exceedances 
    occur during the hot-weather months of May through October. EPA's 
    proposed three month ``de minimis'' period (January 1 to April 1) falls 
    well before the beginning of this season and as a result the ozone 
    benefit of additional controls during this period would be at best, 
    exceedingly small. Thus, the federal implementation of a measure or 
    measures whose sole effect would be to advance by less than 3 months 
    from the April 1, 1999 date on which the 15 percent ROP is met, would 
    clearly yield ``a gain of trivial or no value.''
        EPA does not agree that Delaney bars the use of de minimis 
    exemptions. As discussed previously, the Delaney court itself 
    recognized limits on its conclusion that once a statutory deadline has 
    passed the new deadline becomes ``as soon as possible with all 
    available measures.'' These limits include not requiring measures that 
    would not advance attainment, would cause substantial widespread and 
    long-term adverse impact, or would take too long to implement. These 
    limits clearly indicate that the Delaney court did not expect EPA to 
    impose controls that yield no benefit or a benefit that is outweighed 
    by the implementation burden. Thus, EPA's use of de minimis exemptions 
    is consistent with Delaney.
        Comment: ACLPI notes that EPA predicts that the State will meet the 
    15 percent reduction target by April 1, 1999 with just 0.3 tons per day 
    to spare and argues that this is not a credible demonstration given the 
    size of the inventory and the many uncertainties in EPA's emission 
    reduction predictions. ACLPI asserts that the record here shows that 
    emission reductions expected from control measures do not always 
    materialize.
        Response: The statutory requirement for 15 percent ROP 
    demonstrations is met when the plan demonstrates that it achieves ``at 
    least a 15 percent'' reduction. See section 182(b)(1)(A)(i). Neither 
    the Act nor EPA guidance requires 15 percent ROP demonstrations to 
    include a margin of safety; therefore, reductions greater than the 
    exact amount needed to demonstrate the 15 percent ROP are not required. 
    As a result, the amount of excess emissions in the 15 percent 
    demonstration is immaterial.
        Both the base year inventory used to calculate the 15 percent 
    target emission level and the projected emission inventories and 
    emission reduction calculations were prepared using generally-accepted 
    methodologies consistent with Agency guidance. See the TSD for this 
    rulemaking. As such, they provide a credible and appropriate basis for 
    the 15 percent demonstration and additional adjustments to account for 
    uncertainties are not warranted or required. EPA notes that it already 
    factored into its 15 percent ROP
    
    [[Page 28902]]
    
    demonstration available information on the implementation status of the 
    control measures.
        Because ACLPI neither explains how the size of the inventory 
    relates to the credibility of the demonstration nor provides specifics 
    on the ``many uncertainties in EPA's emission reduction predictions'' 
    or instances where the emission reductions may not materialize, EPA is 
    not able to further respond to this comment.
        Comment: ACLPI comments that EPA proposed to credit 4.4 tons per 
    day in emission reductions from three federal rulemakings that are 
    still at the proposal stage and asserts that such an approach violates 
    the Act and EPA policy. ACLPI supports that assertion by stating that 
    under section 182(b)(1)(c) of the Act, credit can be claimed only for 
    rules ``promulgated'' by EPA and that EPA policy and the Act also 
    forbid the granting of emission reduction credit for measures that have 
    not been legally adopted. ACLPI further argues that there is no 
    assurance whatsoever that the proposed rules will be adopted in a form 
    and on a schedule that will assure the projected emission reductions 
    and without the credit claimed for these measures, the ROP plan does 
    not demonstrate the required 15 percent reduction and therefore is 
    legally deficient.
        Response: Consistent with the Clean Air Act, its policies and its 
    actions on other 15 percent plans, EPA is crediting three proposed 
    national rules in this 15 percent demonstration: consumer products, 
    autobody refinishing and architectural and industrial maintenance 
    coatings. As noted in the proposal, each of these rules are required 
    under CAA section 183(e) and the Agency had recently been sued to 
    enforce the requirement to promulgate these rules. Since the proposal 
    the Agency has agreed to a schedule for their promulgation by August 
    15, 1998. See lodged consent decree in Sierra Club v. Browner, CIV No. 
    97-984 PLF (D.D.C.).
        CAA section 182(b)(1)(A) requires states to submit their 15 percent 
    SIP revisions by November, 1993. Section 182(b)(1)(C) provides the 
    following general rule for creditability of emissions reductions 
    towards the 15 percent requirement: ``emissions reductions are 
    creditable toward the 15 percent required * * * to the extent they have 
    actually occurred, as of [November, 1996], from the implementation of 
    measures required under the applicable implementation plan, rules 
    promulgated by the Administrator, or a permit under Title V.'' CAA 
    section 182(b)(1)(D) further states that certain emissions reductions 
    are not creditable, including reductions from certain control measures 
    required prior to the 1990 Amendments.
        These creditability provisions are ambiguous. Read literally, they 
    provide that, although the 15 percent SIPs are required to be submitted 
    by November 1993, emissions reductions are creditable as part of those 
    SIPs only if ``they have actually occurred, as of [November 1996]''. 
    This literal reading renders the provision internally inconsistent. 
    Accordingly, EPA believes that the provision should be interpreted to 
    provide, in effect, that emissions reductions are creditable ``to the 
    extent they will have actually occurred, as of [November, 1996], from 
    the implementation of [the specified measures]'' (the term ``will'' is 
    added). This interpretation renders the provision internally 
    consistent.
        CAA section 182(b)(1)(C) explicitly includes as creditable 
    reductions those resulting from ``rules promulgated by the 
    Administrator.'' This provision does not state the date by which those 
    measures must be promulgated, i.e., does not indicate whether the 
    measures must be promulgated by the time the 15 percent SIPs were due 
    (November, 1993), or whether the measures may be promulgated after this 
    due date.
        Because the statute is silent on this point, EPA has discretion to 
    develop a reasonable interpretation under Chevron U.S.A. Inc. v. NRDC, 
    467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). EPA believes it 
    reasonable in the first instance to interpret CAA section 182(b)(1)(C) 
    to allow areas to credit reductions from federal measures as long as 
    those reductions are expected to occur by November, 1996, the date for 
    achieving the 15 percent ROP, even if the federal measures are not 
    promulgated by the November, 1993 due date for the 15 percent SIPs.
        EPA's interpretation is consistent with the Congressionally-
    mandated schedule for promulgating regulations for consumer and 
    commercial products, under section 182(e) of the Act. This provision 
    requires EPA to promulgate regulations controlling emissions from 
    consumer and commercial products that generate emissions in 
    nonattainment areas. Under the statutory schedule, by November, 1993--
    the same date that the States were required to submit the 15 percent 
    SIPs--EPA was to issue a report and establish a rulemaking schedule for 
    consumer and commercial products. Further, EPA was to promulgate 
    regulations for the first set of consumer and commercial products by 
    November, 1995. It is reasonable to conclude that Congress anticipated 
    that reductions from these measures would be creditable as part of the 
    15 percent SIPs, as long as those reductions were to occur by November, 
    1996.
        EPA has also established specific policies interpreting the Act 
    that allow crediting of these proposed national measures in 15 percent 
    plans. See Memorandum, John S. Seitz, Director, OAQPS to Regional Air 
    Division Directors; ``Credit for the 15 Percent Rate-of-Progress Plans 
    for Reductions from the Architectural and Industrial Maintenance 
    Coating Rule and the Autobody Refinishing Rule;'' November 29, 1994; 
    Memorandum, John S. Seitz, Director, OAQPS to Regional Air Division 
    Directors; ``Credit for the 15 Percent Rate-of-Progress Plans for 
    Reductions from the Architectural and Industrial Maintenance (AIM) 
    Coating Rule;'' March 22, 1995; Memorandum, John S. Seitz, Director, 
    OAQPS to Regional Air Division Directors; ``Regulatory Schedule for 
    Consumer and Commercial Products under Section 182(e) of the Clean Air 
    Act;'' June 22, 1995; and Memorandum, John S. Seitz, Director of the 
    Office of Air Quality Planning and Standards, and Richard B. Ossias, 
    Deputy Associate General Counsel to Regional Air Division Directors; 
    ``15 Percent VOC SIP Approvals and the `As Soon As Practicable' Test;'' 
    February 12, 1997.
        While this analysis focuses on SIPs, it applies equally to FIPs. As 
    noted before, EPA ``stands in the shoes of the State'' when 
    promulgating a FIP and all the rights and duties available to a state 
    under the Act become available to EPA in a FIP.
        The above analysis also describes statutory provisions that include 
    specific dates for 15 percent SIP submittals (November 15, 1993) and 
    implementation (November 15, 1996). While these dates have expired and 
    new dates for submittal (in this case, promulgation) and implementation 
    have been developed, EPA does not believe that the expiration of the 
    statutory dates, and the development of new ones, invalidates the 
    conclusion that reductions from federal measures promulgated after the 
    date the 15 percent plan is submitted (or promulgated) can be counted 
    toward the ROP demonstration.
        Because it has agreed to a schedule in a proposed consent decree to 
    promulgate these national rules by August 15, 1998, EPA intends to 
    promulgate the rules within 3 months of this FIP promulgation and well 
    before the April 1, 1999 15 percent ROP demonstration date. As a 
    result, crediting reductions from these federal measures is also 
    sensible from an
    
    [[Page 28903]]
    
    administrative standpoint. If it did not credit these national 
    measures, EPA would need to promulgate compensating rules, applicable 
    only to Phoenix, to replace their 4.4 mtpd benefit. EPA has already 
    shown that there are no other measures available that would 
    meaningfully advance the April 1999 date by which the 15 percent ROP is 
    demonstrated in the Phoenix area, thus any additional measures would 
    not result in reductions any sooner than the proposed national rules. 
    Nor would these potential Phoenix-only measures result in any greater 
    reductions creditable to the 15 percent plan since they would simply 
    substitute for the reductions from the national rules.6 
    Thus, if it did not credit the national measures, EPA would simply be 
    engaging in a wasteful rulemaking exercise to promulgate measures in 
    May, 1998 that it could almost immediately withdraw when the national 
    rules are promulgated in August, 1998.7
    ---------------------------------------------------------------------------
    
        \6\ The statutory requirement EPA is fulfilling here is to 
    demonstrate a fixed emission reduction of 15 percent from 1990 base 
    year levels. Emission reductions in excess of this fixed amount are 
    unnecessary. Since EPA has already concluded that the proposed 
    national measures combined with other adopted state and federal 
    measures will result in the required 15 percent ROP as soon as 
    practicable, additional Phoenix-only federal measures are not 
    necessary.
        \7\ In its rulemakings, EPA strives to take the least intrusive 
    and most sensible regulatory approach that achieves the statutory 
    requirements. In this situation, it made no regulatory sense to 
    ignore these pending national measures (which have already been 
    proposed and have near-term date for promulgation) that will apply 
    automatically to Phoenix in favor of promulgating wholly new 
    Phoenix-specific measures.
    ---------------------------------------------------------------------------
    
        The fact that EPA cannot determine precisely the amount of credit 
    available for the proposed national measures does not preclude granting 
    them credit. The credit can be granted as long as EPA is able to 
    develop reasonable estimates of the amount of VOC reductions from the 
    measures EPA expects to promulgate. EPA believes that it is able to 
    develop reasonable estimates, particularly because it has already 
    proposed and taken comment on the measures at issue, and is expecting 
    to promulgate final rules in little less than 3 months. Moreover, the 
    use of estimated emissions and emission reductions rather than actual 
    measurements is a common and necessary practice in attainment and 
    reasonable further progress demonstrations because actual measurements, 
    even for promulgated measures, are seldom available. For example, EPA's 
    document to estimate emissions, ``Compilation of Air Pollutant Emission 
    Factors'', January 1995, AP-42), provide emission factors used to 
    estimate emissions from various sources and source processes. AP-42 
    emission factors have been used, and continue to be used, by states and 
    EPA to determine base year emission inventory figures for sources and 
    to estimate emissions from sources where such information is needed.
        This rulemaking is based on the best information currently 
    available to the Agency on the projected reductions from these proposed 
    national rules. If these projected reductions turn out to be greater 
    than the amount it determines to be appropriate after promulgation of 
    the final rules, then EPA will take appropriate action to revise this 
    15 percent demonstration.
        Comment: ACLPI argues that contrary to EPA's assertion there are a 
    number of additional control measures that are currently available to 
    advance the time for achieving the 15 percent ROP including the use of 
    California's diesel fuel standards (``CARB diesel'') and additional 
    controls on consumer products, both of which are identified in the 
    Report of the Arizona Governor's Air Quality Strategies Task Force 
    (1998) (``1998 Task Force Report'') as are a number of other measures.
        Response: ACLPI is correct that the 1998 Task Force Report shows 
    that adoption of the CARB diesel fuel standards would reduce Phoenix 
    VOC emissions by 7.1 mtpd in 1999. The report, however, also states 
    that implementation of this measure would require at least two years 
    and thus could not occur prior to mid-2000, more than a year after the 
    April 1, 1999 demonstration date for the 15 percent ROP. The State's 
    consultant concluded that the two-year implementation schedule was the 
    minimum necessary after reviewing the refining capacity available to 
    produce CARB diesel fuel for the Phoenix market. See 1998 Task Force 
    Report, p. 77. Since EPA has no grounds to dispute the consultant's 
    conclusions (which were endorsed by the Task Force) regarding the 
    minimum implementation schedule for CARB diesel, it finds the measure 
    would not advance the date by which the 15 percent ROP would be met.
        The Task Force recommended adoption of California's phase I and 
    phase II consumer product standards. These standards are more stringent 
    than EPA's proposed national standards for 13 product categories not 
    currently regulated in Phoenix: single phase aerosol air fresheners, 
    engine degreasers, solid or paste forms of furniture maintenance 
    products, non-aerosol forms of glass cleaners, hairsprays, aerosol 
    insect repellants, nail polish removers, automotive brake cleaners, 
    aerosol dust aids, fabric protectants, crawling bug insecticides, and 
    personal fragrance products.
        Except for hairsprays, California's more stringent limits are 
    already in place. The compliance date for the final VOC limit for 
    hairsprays is June 1, 1999, two months after the April 1, 1999 
    demonstration date for 15 percent ROP in Phoenix. The majority of the 
    emission reductions (or approximately 0.9 metric tons per day) that 
    would result from implementing CARB's consumer products rule in Phoenix 
    come from the final hairspray standard. The balance of the tighter CARB 
    limits produce only a 0.23 mtpd reduction, which EPA finds to be de 
    minimis.
        The 1998 Governor's Task Force evaluated and recommended controls 
    for not only VOC but also nitrogen oxides, carbon monoxide, particulate 
    matter and regional haze. These controls range from I/M program 
    improvements to improved compliance with the area's fugitive dust rules 
    and include numerous study proposals (e.g., Transit Task Force). Since 
    ACLPI was not specific about what additional control measures EPA 
    should evaluate for this plan, it is not possible for EPA to respond in 
    more detail to this comment.
    
    III. Conclusion
    
        Pursuant to its federal planning authority under CAA section 110(c) 
    and for the reasons discussed above, EPA is determining that the 
    Phoenix metropolitan area has in place or will have in place sufficient 
    control measures to meet the 15 percent ROP requirement for VOCs in CAA 
    section 182(b)(1)(A) as soon as practicable.
        EPA is also approving the State's 1990 base year inventory for the 
    Phoenix area under CAA sections 110(k)(2) and 182(a)(1).
        Under 40 CFR 93.118(e), this final action establishes a VOC 
    conformity budget of 76.7 metric tons per average summer day based on 
    the inventory methodology and mobile source emissions model used for 
    this 15 percent ROP demonstration. This conformity budget is in 
    addition to, and not in lieu of, the conformity budget established in 
    the MAG 1993 Ozone Plan for the Maricopa County Area, Modeling 
    Attainment Demonstration (October 1994).
    
    IV. Administrative Requirements
    
    A. Executive Order (E.O.) 12866
    
        The Office of Management and Budget has exempted this action from 
    E.O. 12866 review.
    
    [[Page 28904]]
    
    B. Regulatory Flexibility Act
    
        Under the Regulatory Flexibility Act, 5 U.S.C. Section 601 et seq., 
    EPA must prepare a regulatory flexibility analysis assessing the impact 
    of any proposed or final rule on small entities. 5 U.S.C. sections 603 
    and 604. Alternatively, EPA may certify that the rule will not have a 
    significant economic impact on a substantial number of small entities. 
    Small entities include small businesses, small not-for-profit 
    enterprises, and government entities with jurisdiction over populations 
    of less than 50,000.
        This action simply presents the analysis of the emission impacts on 
    the Phoenix metropolitan area of already adopted or proposed State and 
    federal rules. This action neither promulgates additional measures nor 
    requires Arizona or its local jurisdictions to adopt or implement 
    additional measures beyond those that they currently have adopted and 
    implemented or have been proposed or implemented at the federal level. 
    As such, it does not regulate any entities. Therefore, pursuant to 5 
    U.S.C. 605(b), EPA certifies that today's action does not have a 
    significant impact on a substantial number of small entities within the 
    meaning of those terms for RFA purposes.
    
    C. 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, when EPA promulgates ``any general notice of proposed 
    rulemaking that is likely to result in promulgation of any rule that 
    includes any Federal mandate that may result in the expenditures by 
    State, local, and tribal governments, in the aggregate, or by the 
    private sector, of $100 million or more'' in any one year. A ``Federal 
    mandate'' is defined, under section 101 of UMRA, as a provision that 
    ``would impose an enforceable duty'' upon the private sector or State, 
    local, or tribal governments'', with certain exceptions not here 
    relevant. Under section 203 of UMRA, EPA must develop a small 
    government agency plan before EPA ``establish[es] any regulatory 
    requirements that might significantly or uniquely affect small 
    governments.'' Under section 204 of UMRA, EPA is required to develop a 
    process to facilitate input by elected officers of State, local, and 
    tribal governments for EPA's ``regulatory proposals'' that contain 
    significant Federal intergovernmental mandates. Under section 205 of 
    UMRA, before EPA promulgates ``any rule for which a written statement 
    is required under [UMRA section] 202'', EPA must identify and consider 
    a reasonable number of regulatory alternatives and either adopt the 
    least costly, most cost-effective or least burdensome alternative that 
    achieves the objectives of the rule, or explain why a different 
    alternative was selected.
        As explained above, sections 202, 203, 204, and 205 of UMRA do not 
    apply to today's action because it does not impose an enforceable duty 
    on or otherwise affect any entity. Therefore, EPA is not required, and 
    has not taken, any actions under UMRA.
    
    D. E.O. 13045: Protection of Children From Environmental Health Risks 
    and Safety Risks
    
        Executive Order 13045, entitled ``Protection of Children from 
    Environmental Health Risks and Safety Risks (62 FR 19885 (April 23, 
    1997)), applies to any rule that EPA determines (1) ``economically 
    significant'' as defined under E.O. 12866 and (2) the environmental 
    health or safety risk addressed by the rule has 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.
        Today's final action promulgating a demonstration that the Phoenix 
    area meets the 15 percent VOC ROP requirement in CAA section 
    182(b)(1)(A)(i) is not subject to E.O. 13045 because it is not an 
    economically significant regulatory action as defined by E.O and 
    because it does not involve decisions on environmental health risks or 
    safety risks that may disproportionately affect children.
    
    E. Submission to Congress and the General Accounting Office
    
        The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
    Small Business Regulatory Enforcement Fairness Act of 1996, generally 
    provides that before a rule may take effect, the agency promulgating 
    the rule must submit a rule report, which includes a copy of the rule, 
    to each House of the Congress and to the Comptroller General of the 
    United States. EPA will submit a report containing this rule and other 
    required information to the U.S. Senate, the U.S. House of 
    Representatives, and the Comptroller General of the United States prior 
    to publication of the rule in the Federal Register. This rule is not a 
    ``major'' rule as defined by 5 U.S.C. 804(2).
    
    F. Petitions for Judicial Review
    
        Under section 307(b)(1) of the Clean Air Act, petitions for 
    judicial review of this action must be filed in the United States Court 
    of Appeals for the appropriate circuit by July 27, 1998. Filing a 
    petition for reconsideration by the Administrator of this final rule 
    does not affect the finality of this rule for the purposes of judicial 
    review nor does it extend the time within which a petition for judicial 
    review may be filed, and shall not postpone the effectiveness of such 
    rule or action. This action may not be challenged later in proceedings 
    to enforce its requirements. (See section 307(b)(2)).
