    Clean Air Act Approval and Promulgation of PM10 
    Implementation Plan for Montana
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: In this action, EPA approves the State implementation plan 
    (SIP) submitted by the State of Montana to achieve attainment of the 
    National ambient air quality standards (NAAQS) for particulate matter 
    with an aerodynamic diameter less than or equal to a nominal 10 
    micrometers (PM10). The SIP was submitted by Montana to satisfy 
    certain Federal requirements for an approvable moderate nonattainment 
    area PM10 SIP for Missoula. In this final rule, EPA also approves 
    the Missoula City-County Air Pollution Control Program, except several 
    rules regarding emergency procedures, permitting, open burning, wood-
    waste burners, new source performance standards, hazardous air 
    pollutant standards, and variances. EPA will propose separate action on 
    these rules when the State fulfills its related commitments. One 
    commitment has been fulfilled (see the This Action section of this 
    document for more information). If the State fails to fulfill the 
    remainder of its commitments, EPA will take appropriate action. 
    Further, EPA is declining to take action on Missoula's odor provisions.
    
    EFFECTIVE DATE: This rule will become effective on February 17, 1994.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        The Missoula, Montana area was designated nonattainment for 
    PM10 and classified as moderate under sections 107(d)(4)(B) and 
    188(a) of the Clean Air Act, upon enactment of the Clean Air Act 
    Amendments of 1990.1 See 56 FR 56694 (November 6, 1991); 40 CFR 
    81.327 (Missoula and vicinity). The air quality planning requirements 
    for moderate PM10 nonattainment areas are set out in subparts 1 
    and 4 of part D, title I of the Act.
    ---------------------------------------------------------------------------
    
        \1\The 1990 Amendments to the Clean Air Act made significant 
    changes to the air quality planning requirements for areas that do 
    not meet (or that significantly contribute to ambient air quality in 
    a nearby area that does not meet) the PM10 National Ambient Air 
    Quality Standards (see Public Law No. 101-549, 104 Stat. 2399). 
    References herein are to the Clean Air Act, as amended (``the 
    Act''), 42 U.S.C. 7401, et seq.
    ---------------------------------------------------------------------------
    
        EPA has issued a ``General Preamble'' describing its preliminary 
    views on how EPA intends to review SIPs and SIP revisions submitted 
    under title I of the Act, including those State submittals containing 
    moderate PM10 nonattainment area SIP requirements (see generally 
    57 FR 13498 (April 16, 1992) and 57 FR 18070 (April 28, 1992)). Because 
    EPA is describing its interpretations here only in broad terms, the 
    reader should refer to the General Preamble for a more detailed 
    discussion of the interpretations of title I advanced in this final 
    action and the supporting rationale.
        Those States containing initial moderate PM10 nonattainment 
    areas (i.e., those areas designated nonattainment for PM10 under 
    section 107(d)(4)(B) of the Act) were required to submit, among other 
    things, the following provisions by November 15, 1991:
    
        1. Provisions to assure that reasonably available control measures 
    (RACM) (including such reductions in emissions from existing sources in 
    the area as may be obtained through the adoption, at a minimum, of 
    reasonably available control technology (RACT)) shall be implemented no 
    later than December 10, 1993;
        2. Either a demonstration (including air quality modelling) that 
    the plan will provide for attainment as expeditiously as practicable 
    but no later than December 31, 1994, or a demonstration that attainment 
    by that date is impracticable;
        3. Quantitative milestones which are to be achieved every 3 years 
    and which demonstrate reasonable further progress (RFP) toward 
    attainment by December 31, 1994; and
        4. Provisions to assure that the control requirements applicable to 
    major stationary sources of PM10 also apply to major stationary 
    sources of PM10 precursors except where the Administrator 
    determines that such sources do not contribute significantly to 
    PM10 levels which exceed the NAAQS in the area. See sections 
    172(c), 188, and 189 of the Act.
        Some provisions are due at a later date. States with initial 
    moderate PM10 nonattainment areas were required to submit a permit 
    program for the construction and operation of new and modified major 
    stationary sources of PM10 by June 30, 1992 (see section 189(a)). 
    Such States also must submit contingency measures by November 15, 1993 
    that become effective without further action by the State or EPA, upon 
    a determination by EPA that the area has failed to achieve RFP or to 
    attain the PM10 NAAQS by the applicable statutory deadline. See 
    section 172(c)(9) and 57 FR 13543-13544.
        On September 15, 1993, EPA announced its proposed approval of the 
    Missoula, Montana moderate nonattainment area PM10 SIP, including 
    parts of the Missoula City-County Air Pollution Control Program, as 
    meeting those moderate nonattainment area PM10 SIP requirements 
    due on November 15, 1991 (58 FR 48339-48343). In that proposed 
    rulemaking action and related Technical Support Document (TSD), EPA 
    described in detail its interpretations of title I and its rationale 
    for proposing to approve the Missoula moderate nonattainment area 
    PM10 SIP, taking into consideration the specific factual issues 
    presented.
        EPA requested public comments on all aspects of the proposal 
    (please reference 58 FR 48343), and comments from the State of Montana 
    and Stone Container Corporation were received during the comment 
    period, which ended on October 15, 1993. (For further discussion of 
    these public comments, please see below and the Addendum to the TSD for 
    EPA's proposed rulemaking action on this SIP.) This final action on the 
    Missoula moderate nonattainment area PM10 SIP, and portions of the 
    Missoula City-County Air Pollution Control Program, is unchanged from 
    the September 15, 1993 proposed approval action, except for two 
    typographical errors noted by EPA. First, in the table describing 
    sources, controls, emission reductions, and effective dates, the 
    effective date for the Louisiana-Pacific permit modification should 
    have been listed as March 20, 1992 instead of January 23, 1992, as 
    indicated. Second, under the Enforceability Issues section, the final 
    modification date for Stone Container Corporation's air quality permit 
    #2589-M should have been January 23, 1992 instead of November 25, 1992, 
    as indicated.
        The discussion herein provides only a broad overview of the 
    proposed action EPA is now finalizing. The public is referred to the 
    September 15, 1993 proposed rule for a more in-depth discussion of the 
    action now being finalized.
    
    II. Response to Comments
    
        EPA did not receive any adverse public comments regarding its 
    September 15, 1993 proposed approval of the Missoula moderate 
    nonattainment area PM10 SIP (58 FR 48339-48343). However, the 
    State of Montana submitted comments for clarification purposes, and 
    Stone Container Corporation submitted comments to express general 
    support for EPA's action. Comments were as follows.
        In a letter dated September 24, 1993 from Jeff Chaffee, Montana 
    Department of Health and Environmental Sciences, to Amy Platt, EPA, and 
    through verbal communications, the State indicated that since 
    submitting the original moderate nonattainment area PM10 SIP for 
    Missoula, it discovered a minor arithmetic error in its 24-hour 
    attainment and maintenance demonstrations, as well as an error in the 
    way it had addressed background concentrations in both the 24-hour and 
    annual attainment and maintenance demonstrations. The background 
    concentrations, i.e., naturally occurring PM10 concentrations that 
    cannot be controlled, had not been subtracted from the 24-hour and 
    annual design values before apportioning the credits derived from the 
    outlined control measures. The State has corrected these calculations, 
    and with the adjustments, the 24-hour and annual attainment values 
    (i.e., ambient PM10 air quality levels achieved by 19952) are 
    as follows: 143.8 g/m3 and 44.7 g/m3, 
    respectively. (Before these adjustments, the 24-hour and annual 
    attainment values were 142.1 g/m3 and 45.3 g/
    m3, respectively.) The adjusted 24-hour and annual maintenance 
    values (i.e., ambient PM10 air quality levels maintained through 
    January 1, 1998) are 147.0 g/m3 and 45.5 g/
    m3, respectively. (Before these adjustments, the 24-hour and 
    annual maintenance values were 145.2 g/m3 and 46.2 
    g/m3, respectively.)
    ---------------------------------------------------------------------------
    
        \2\The Clean Air Act calls for attainment by December 31, 1994. 
    Section 188(c)(1). EPA interprets the State's demonstration as 
    providing for attainment by January 1, 1995. EPA is approving the 
    State's demonstration on the basis of the de minimis differential 
    between the two dates.
    ---------------------------------------------------------------------------
    
        Since these corrected calculations are based on properly handling 
    the background concentration and since the adjusted values still 
    adequately demonstrate attainment and maintenance of the PM10 
    NAAQS and do not represent major changes to those considered in EPA's 
    proposed action, EPA is proceeding with its approval of this SIP. There 
    is no need to adopt additional control measures based on these adjusted 
    calculations.
        Comments were also received in an October 11, 1993 letter from 
    Larry Weeks, Stone Container Corporation, to Amy Platt, EPA. The 
    comments were not adverse and expressed general support for EPA's 
    action on the Missoula PM10 SIP. However, several of Stone 
    Container's comments indicate a misunderstanding of EPA's intended 
    action on this SIP and need further explanation.
        First, EPA did not propose to approve the odor control rules 
    contained in the SIP submittal and Stone Container communicated its 
    support but referenced ``Montana's odor control rules.'' EPA's action 
    regarding odor regulations applies specifically to the Missoula City-
    County regulation (Chapter IX, Subchapter 14, Rule 1427) contained in 
    the SIP submittal.
        Second, Stone Container submitted comments suggesting it viewed the 
    reduction in allowable PM10 emissions from its No. 5 recovery 
    boiler as voluntary reductions. Stone Container's recovery boilers were 
    identified by chemical mass balance receptor modelling to contribute 
    8.1% of the PM10 ambient concentrations in Missoula. The SIP 
    submittal demonstrated that Stone Container is contributing to the 
    PM10 nonattainment problem in the Missoula and vicinity 
    nonattainment area and that reductions in allowable emissions from 
    recovery boiler No. 5 are part of an enforceable permit that are 
    necessary to demonstrate expeditious attainment of the PM10 NAAQS 
    in the area. EPA agrees with the State's judgement that the reduction 
    in allowable emissions from recovery boiler No. 5 is necessary to 
    ensure expeditious attainment of the PM10 NAAQS in the area. EPA's 
    final approval of this limitation means that it will become part of the 
    federally enforceable implementation plan. See, e.g., sections 113 and 
    302(q) of the Act.
        Next, Stone Container commented that because EPA proposed to 
    approve the control requirement exclusion for major stationary sources 
    of PM10 precursors authorized by section 189(e) of the Act, it 
    would not make sense for the SIP to include contingency measures that 
    would call for limitations on industrial sources. Contingency measures 
    for moderate PM10 nonattainment areas are due to EPA no later than 
    November 15, 1993 and were not submitted by the State as part of the 
    SIP revisions being addressed in this action. Thus, this comment is 
    misplaced and does not address a matter within the scope of the 
    September 15, 1993 proposed action on the SIP submittals for the 
    Missoula area. For clarification purposes, EPA simply notes that EPA's 
    finding that major sources of PM10 precursors do not contribute 
    significantly to PM10 levels in excess of the NAAQS in Missoula 
    addresses PM10 precursors only. Note that this finding is based on 
    the current character of the area including, for example, the existing 
    mix of sources in the area. It is possible, therefore, that future 
    growth could change the significance of precursors in the area. Stone 
    Container has been shown to be currently contributing to primary 
    PM10 emissions in Missoula.
        Finally, since Stone Container has been shown to contribute to the 
    PM10 ambient concentrations in Missoula, contingency measures that 
    include limitations on its emissions could be sought by the State. 
    Although Stone Container is located outside the nonattainment area, it 
    is still a contributing source (approximately 8% of the PM10 
    ambient concentrations in Missoula). Therefore, it may be necessary and 
    reasonable to include emission reductions at Stone Container as part of 
    the contingency measures for Missoula. EPA will reserve judgement on 
    the adequacy of any contingency measures submitted by the State until 
    such time as EPA receives a contingency measure submittal and provides 
    public notice and opportunity for public comment on its adequacy.
    
    This Action
    
        Section 110(k) of the Act sets out provisions governing EPA's 
    review of SIP submittals (see 57 FR 13565-13566). The Governor of 
    Montana submitted the Missoula PM10 SIP with a letter dated June 
    4, 1992, and requested that EPA take action on the June 4, 1992 
    submittal together with the August 20, 1991 submittal of the Missoula 
    City-County Air Pollution Control Program. The submittals taken 
    together were intended to satisfy those moderate nonattainment area 
    PM10 SIP requirements due for Missoula on November 15, 1991. As 
    described in EPA's proposed action on this SIP (58 FR 48339-48343, 
    September 15, 1993), the Missoula moderate nonattainment area PM10 
    plan includes, among other things, a comprehensive and accurate 
    emissions inventory, control measures that satisfy the RACM 
    requirement, a demonstration (including air quality modelling) that 
    attainment of the PM10 NAAQS will be achieved by January 1, 1995 
    (see footnote #2), provisions for meeting the November 15, 1994 
    quantitative milestone and reasonable further progress, and 
    enforceability documentation. Further, EPA proposed to determine that 
    major sources of precursors of PM10 do not contribute 
    significantly to PM10 levels in excess of the NAAQS in 
    Missoula.3 Please refer to EPA's notice of proposed rulemaking (58 
    FR 48339) and the TSD for that action for a more detailed discussion of 
    these elements of the Missoula plan.
    ---------------------------------------------------------------------------
    
        \3\The consequences of this finding are to exclude these sources 
    from the applicability of PM10 nonattainment area control 
    requirements. Note that EPA's finding is based on the current 
    character of the area including, for example, the existing mix of 
    sources in the area. It is possible, therefore, that future growth 
    could change the significance of precursors in the area.
    ---------------------------------------------------------------------------
    
        In this final rulemaking, EPA announces its approval of those 
    elements of the Missoula, Montana moderate nonattainment area PM10 
    SIP that were due on November 15, 1991, and submitted on August 20, 
    1991 and June 4, 1992. In this final action, EPA is also announcing its 
    approval of the Missoula City-County Air Pollution Control Program 
    regulations (which were submitted on August 20, 1991 and June 4, 1992) 
    except for the following provisions: Chapter IX-Subchapter 4, Emergency 
    Procedures; Subchapter 11, Permit, Construction & Operation of Air 
    Contaminant Sources; Subchapter 13, Open Burning; Subchapter 14, Rule 
    1407, Wood-Waste Burners, Rule 1423, Standard of Performance for New 
    Stationary Sources (NSPS), Rule 1424, Emission Standards for Hazardous 
    Air Pollutants (NESHAPs), and Rule 1427, Control of Odors in Ambient 
    Air; and Chapter X, Variances. EPA described the deficiencies 
    associated with these rules in its notice of proposed rulemaking and 
    the TSD for that action.
        EPA finds that the State of Montana's PM10 SIP for the 
    Missoula moderate nonattainment area meets the Reasonably Available 
    Control Measures (RACM), including Reasonably Available Control 
    Technology (RACT), requirement. Five sources/source categories were 
    identified as contributing to the PM10 nonattainment problem in 
    Missoula and, therefore, were targeted for control in the SIP. The 
    State has demonstrated that by applying control measures to area 
    sources (re-entrained road dust, residential wood combustion, 
    prescribed burning, and motor vehicle exhaust), as well as reducing 
    allowable emissions through air quality permit modifications for 
    Louisiana-Pacific and Stone Container, Missoula will be in attainment 
    by January 1, 1995 (see footnote #2). It does not appear that applying 
    further control measures to these sources would expedite attainment. 
    EPA views the following measures as reasonable, enforceable, and 
    responsible for significant PM10 emissions reductions in Missoula: 
    (a) Missoula County Rule 1401(7), which sets sanding and chip sealing 
    standards and street sweeping and flushing requirements; (b) Missoula 
    County Rule 1401(9), which establishes liquid de-icer requirements; (c) 
    industry permit modifications made to reduce allowable PM10 
    emissions from Stone Container Corporation's recovery boiler No. 5 and 
    Louisiana-Pacific Corporation's particle board dryers; and (d) the 
    Federal tailpipe standards, which provide an ongoing benefit due to 
    fleet turnover. Further, although no credit was claimed in the SIP, EPA 
    is approving the following measures to make them federally enforceable 
    and to further strengthen the SIP. The measures provide additional 
    PM10 air quality protection. These measures are: (a) Missoula 
    County Rule 1428, which sets standards for the regulation for solid 
    fuel burning devices; and (b) Missoula County Rule 1310(3), which sets 
    standards for the regulation of prescribed wildland open burning.
        A more detailed discussion of the individual source contributions, 
    their associated control measures (including available control 
    technology) and an explanation of why certain available control 
    measures were not implemented, can be found in the TSD accompanying 
    EPA's proposed approval of the Missoula moderate PM10 
    nonattainment area SIP (58 FR 48339-48343). EPA has reviewed the 
    State's documentation and concluded that it adequately justifies the 
    control measures to be implemented. The implementation of Montana's 
    PM10 nonattainment plan for Missoula will result in the attainment 
    of the PM10 NAAQS by January 1, 1995 (see footnote #2). By this 
    notice EPA is approving the Missoula PM10 moderate nonattainment 
    area plan's control measures as satisfying the RACM, including RACT, 
    requirement.
        As noted, EPA did not propose approval, nor is EPA taking final 
    action, on some portions of the Missoula City-County Air Pollution 
    Control Program regulations. To address EPA-identified deficiencies in 
    the Missoula and statewide SIP, the State committed to complete 
    additional tasks to correct these deficiencies (except the concerns EPA 
    raised regarding the variance provisions). A more detailed explanation 
    of the State's commitments can be found in EPA's September 15, 1993 
    proposed approval of the Missoula moderate nonattainment area PM10 
    SIP (58 FR 48339-48343) and the TSD for that action). Since none of the 
    rules associated with these commitments has an impact on the attainment 
    demonstration, credited control strategies in the Missoula PM10 
    SIP, or other Federal Clean Air Act SIP requirements for the Missoula 
    moderate PM10 nonattainment area due to EPA on November 15, 1991, 
    EPA will take separate action, as appropriate, when such commitments 
    are fulfilled by the State, and also will address the variances chapter 
    at that time. Further, EPA is declining to take action on Chapter IX, 
    Subchapter 14: Rule 1427, Control of Odors in Ambient Air. These odor 
    provisions do not have a reasonable connection to the NAAQS-related air 
    quality goals of the Clean Air Act.
        The State has fulfilled one commitment to revise its NSPS and 
    NESHAPs regulations to incorporate all Federal requirements promulgated 
    through July 1, 1992. In a March 9, 1993 submittal, the State satisfied 
    this commitment, and EPA will announce its action on these revisions in 
    a separate notice.
        Nothing in this action should be construed as permitting or 
    allowing or establishing a precedent for any future request for a 
    revision to any SIP. Each request for a revision to the SIP shall be 
    considered separately in light of specific technical, economic, and 
    environmental factors, and in relation to relevant statutory and 
    regulatory requirements.
    
    Final Action
    
        This document announces EPA's final action on the action proposed 
    at 58 FR 48339. As noted elsewhere in this final action, EPA received 
    no adverse public comments on the proposed action. As a direct result, 
    the Regional Administrator has reclassified this action from Table 1 to 
    Table 3 under the processing procedures established at 54 FR 2214, 
    January 19, 1989.
    
    Regulatory Process
    
        Under the Regulatory Flexibility Act, 5 U.S.C. 600, 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. 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.
        SIP approvals under section 110 and subchapter I, part D of the 
    Clean Air Act do not create any new requirements, but simply approve 
    requirements that the State is already imposing. Therefore, because the 
    Federal SIP-approval does not impose any new requirements, I certify 
    that it does not have a significant impact on a substantial number of 
    small entities affected. Moreover, due to the nature of the Federal-
    state relationship under the Clean Air Act, preparation of a regulatory 
    flexibility analysis would constitute Federal inquiry into the economic 
    reasonableness of state action. The Clean Air Act forbids EPA to base 
    its actions concerning SIPs on such grounds. Union Electric Co. v. U.S. 
    E.P.A., 427 U.S. 246, 256-66 (1976); 42 U.S.C. 7410(a)(2).
        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 March 21, 1994. 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 file, 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).)
    
    Executive Order (EO) 12866
    
        This action has been classified as a Table 3 action by the Regional 
    Administrator under the procedures published in the Federal Register on 
    January 19, 1989 (54 FR 2214-2225). On January 6, 1989, the Office of
