    SUMMARY: The Environmental Protection Agency (EPA) is redesignating the 
    Portland/Vancouver (Pdx/Van) interstate nonattainment area to 
    attainment for the ozone (O3) air quality standard and 
    approving a Maintenance Plan that will insure that the area remains in 
    attainment. Under the Clean Air Act, as amended in 1990 (the CAA), 
    designations can be revised if sufficient data are available to warrant 
    such revisions and the request to redesignate shows that all of the 
    requirements of section 107(d)(E)(3) of the CAA have been met. EPA is 
    approving the Washington and Oregon Maintenance Plans and other 
    redesignation submittals because they meet the Maintenance Plan and 
    redesignation requirements, and will ensure that the area remains in 
    attainment. The approved Maintenance Plans will become a federally 
    enforceable part of the Oregon and Washington State Implementation 
    Plans (SIPs). In this action, EPA is also approving the Washington and 
    Oregon 1990 baseline emission inventories for this area, revisions to 
    the approved Inspection and Maintenance (I/M) SIPs of both States, and 
    a number of other O3 supporting revisions to both SIPs.
    
    DATES: June 18, 1997.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
        The Oregon Department of Environmental Quality (ODEQ) and the 
    Washington Department of Ecology (WDOE) submitted Maintenance Plans and 
    requested redesignation of the Pdx/Van interstate nonattainment area 
    from nonattainment to attainment for O3. The SIP revision 
    requests were submitted by the WDOE on June 13, 1996, and by ODEQ on 
    August 30, 1996. No tribal lands are within the Maintenance Plan area 
    nor have any tribal lands been identified as being affected by the 
    Maintenance Plans.
        The Pdx/Van air quality maintenance area (AQMA) was designated an 
    interstate O3 nonattainment area in 1978 under the 1977 CAA. 
    On November 15, 1990, the CAA Amendments of 1990 were enacted (Pub. L. 
    101-549, 104 Stat. 2399, codified at 42 U.S.C. 7401-7671q). Under 
    section 181(a)(1) of the CAA, the area was further classified as a 
    ``marginal'' O3 nonattainment area, and an attainment 
    deadline of November 15, 1993, was established. This interstate 
    nonattainment area consists of the southern portion of Clark County, 
    Washington, and portions of Multnomah, Clackamas, and Washington 
    Counties in Oregon.
        The AQMA has ambient monitoring data that show no violations of the 
    O3 national ambient air quality standards (NAAQS) during the 
    period of 1991 to the present. The WDOE and ODEQ provided these 
    monitoring data and modeling and emissions data to support their 
    redesignation request. On March 7, 1997, EPA proposed to approve the 
    WDOE's and ODEQ's requested redesignation. In its notice of proposed 
    approval and redesignation, EPA reviewed in detail the submittals it 
    was considering as the basis for its proposed actions.
    
    II. Response To Comments
    
        The following comments were received during the public comment 
    period ending April 7, 1997. EPA's response follows each comment.
        (1) Comment: The commenter asserted that, while the Maintenance 
    Plan for Clark County relies heavily on expanding the automobile 
    inspection area, there are no data on hand to support a theory that 
    auto emissions from that expanded area are significant contributors to 
    high ozone events.
        Response: EPA has reviewed the Vancouver portion of the Pdx/Van 
    O3 Redesignation Request/Maintenance Plan and believes that 
    the Southwest Air Pollution Control Authority (SWAPCA) has a reasonable 
    basis for deciding to expand the maintenance area. EPA notes that the 
    expansion of the automobile inspection testing into Northern Clark 
    County is only one of several parts of the Vancouver Maintenance Plan. 
    Emission reductions are also being obtained from the approximately 
    170,000 vehicles in southern Clark County by: switching to a more 
    sophisticated emission test procedure (known as ASM) (setting ASM 
    standards for exhaust emissions will result in an enhanced ability to 
    identify polluting vehicles); gasoline cap leak checks; stage I and II 
    vapor controls on gasoline vapors; application of the EPA national off-
    road engine rule; Volatile Organic Compound (VOC) Area Source rules 
    targeting emissions from consumer products, architectural and 
    industrial maintenance coatings, and autobody refinishing; and phase-
    out of open burning. Also, new industry or existing industry 
    modifications will continue to be subject to Best Available Control 
    Technology (BACT) and will still be subject to these controls under the 
    O3 Maintenance Plan.
        SWAPCA has provided the following Census data to support the 
    expanded boundary portion of the Vancouver Maintenance Plan. The 1990 
    U.S. Census commuter statistics outlined below demonstrate North Clark 
    County motor vehicles are contributing to the air pollution problem:
    
    --51.9% (5,046 citizens) of Battle Ground zipcode residents who are 
    employed commute to the City of Vancouver and Portland for their work;
    --65.3% (1,162 citizens) of Brush Prairie zipcode residents who are 
    employed commute to the City of Vancouver and Portland for their work;
    --58.4% (2,816) of Ridgefield zipcode residents who are employed 
    commute to the City of Vancouver and Portland for their work; and
    --42.5% (2,185) of La Center zipcode residents who are employed commute 
    to the City of Vancouver and Portland for their work.
    
        EPA also notes that SWAPCA's decision to expand the automobile 
    maintenance area was made after SWAPCA had followed the public 
    participation requirements that are established under State law and 
    meet the requirements of the CAA.
    
    [[Page 27205]]
    
        (2) Comment: The same commenter on the Vancouver Maintenance Plan 
    wrote that, when the vast amount of naturally occurring VOCs are taken 
    into account, it should be obvious that nitrogen oxides 
    (NOX) are the critical factor and that the large industrial 
    sources of that compound must be considered. Because the commenter 
    believes it would cost less to equip industrial sources with 
    NOX controls than to extend the auto test area for an equal 
    O3 reduction, the commenter believes that the Maintenance 
    Plan is designed to favor industry at public expense.
        Response: Information provided by SWAPCA to EPA shows that cars 
    make up about 35% of the VOC emissions and over 50% of the 
    NOX emissions in the nonattainment area. The portion of 
    vehicle miles travelled (VMT) in the nonattainment area which comes 
    from North Clark County cars is 15%, which is substantial. SWAPCA 
    believes that targeting these emissions with an expansion of the I/M 
    program will reduce emissions by approximately 180 tons/year of VOCs 
    and 150 tons/year of NOX, and will result in an additional 
    30,000 vehicles being tested every two years.
        The documentation utilized by SWAPCA supports its views that 
    additional NOX controls on industry are not as cost 
    effective as those being proposed in the Maintenance Plan ($2,500-
    $7,000/ton for industrial NOX control versus $100-$2000/ton 
    for a vehicle inspection program.) The CAA also targets larger 
    industrial sources with new permitting requirements. Therefore, 
    industry will still be required to complete BACT for any new sources or 
    modification. Information submitted by SWAPCA also shows that emissions 
    from naturally occurring VOCs were taken into account and that 
    controlling NOX emissions was considered. SWAPCA anticipates 
    there will be NOX reductions from the improved vehicle 
    inspection program, from continuance of BACT for industrial sources, 
    and from the EPA non-road engine rule for nonroad sources.
        (3) Comment: A commenter requested that EPA not approve the 
    Vancouver Maintenance Plan until SWAPCA modifies the emission inventory 
    contained in the plan and EPA revises its guidance dealing with 
    projection inventories contained in Section 3.2.3 of ``Emission 
    Inventory Requirements for Ozone State Implementation Plans.'' This 
    comment concerns SWAPCA's decision to not include future emissions from 
    certain major emitters in the Longview area, although prior 
    correspondence from EPA stated that those sources must be included 
    because they are within 25 miles of the boundary of the nonattainment 
    area. SWAPCA added them to the 1992 base inventory, but the commenter 
    asserts SWAPCA did not include projections of those emissions through 
    the 10 year maintenance period because it is not expressly required by 
    EPA's guidance. The commenter wrote that the Weyerhaueser and Longview 
    Fibre pulp mills in Longview, Washington, are the largest emitters of 
    NOx and VOCs in the area, and their emissions are growing as their new 
    expansions come on stream. In addition, the prevailing winds in the 
    summer blow directly from these plants toward Vancouver. The commenter 
    believes that it is a gross distortion of the projected inventories to 
    exclude them and it has resulted in the application of controls to 
    other much smaller emitters that are not equitable. The commenter also 
    requested that EPA postpone reclassification of the Pdx/Van area until 
    these changes are made.
        Response: EPA believes the issue raised in this comment has been 
    appropriately addressed by SWAPCA in the Vancouver portion of the 
    O3 Maintenance Plan. Furthermore, EPA does not believe there 
    is any basis to delay action on these SIP revisions and 
    reclassification of this area until revision of the applicable 
    guidance.
        For reclassification of the Pdx/Van area, a marginal O3 
    nonattainment area, EPA requires completion of an emission inventory. 
    The emission inventory approach is defined as calculating the emissions 
    within the nonattainment area plus industrial source emissions (greater 
    than 100 tons per year) that are within a 25 mile radius. The Longview 
    sources were included in the 1992 emission inventory for point sources 
    in Appendix D of the Vancouver portion of the O3 Maintenance 
    Plan.
        EPA also requires that the Maintenance Plan project emissions to 
    demonstrate the NAAQS for O3 will be maintained for a 10 
    year period after redesignation. More detailed computer modeling 
    required to justify redesignation decisions in severe O3 
    nonattainment areas is not necessary to support redesignation of a 
    marginal area.
        In deciding to not include the sources cited by the commenter in 
    the Maintenance Plan projections, SWAPCA reasonably relied on a 
    preliminary screening model to conclude that these sources contribute 
    between 1% to 10% of their emissions to the nonattainment area. SWAPCA 
    decided to wait for the results of ``future studies'' before 
    determining whether additional control measures are needed on these 
    sources to maintain healthy air in Clark County. In reference to the 
    wind direction issue, SWAPCA's information indicates that the closest 
    meteorological station to Vancouver is the Portland International 
    Airport. However, SWAPCA is concerned that the data from the Portland 
    International Airport are not representative of the entire Vancouver 
    area. A review of available windspeed data on high O3 days 
    by SWAPCA and ODEQ indicates wind speeds are not uniform throughout the 
    day in the Pdx/Van area. Also, winds travel at different speeds and 
    directions at different altitudes. Modeling of air pollution impacts 
    would need to consider these factors as well as the height of the 
    stacks and plumes from point sources. In the fall of 1996, a local 
    meteorological station was installed in Vancouver which will better 
    help SWAPCA to anticipate inversion conditions. In the Pdx/Van 
    Redesignation Request/Maintenance Plan, SWAPCA committed to completing 
    ``future studies'' to estimate the contribution of emissions from these 
    sources to the Pdx/Van O3 area. Additional O3 and 
    NOx monitors have been purchased which were to be operational by May 1, 
    1997. As these data are collected and additional funding is obtained 
    for the modeling efforts, SWAPCA expects it will be possible to address 
    the issue raised by this comment using sound scientific data.
        EPA also notes that, if the Weyerhaeuser and Longview Fibre pulp 
    mills in Longview expand, they will undergo Prevention of Significant 
    Deterioration (PSD) review which evaluates BACT and also will conduct 
    an ambient impact analysis to ensure that the NAAQS and PSD increment 
    will not be violated.
        EPA will not agree to delay the approval of the Maintenance Plan 
    and the redesignation of this area to attainment. Under Title I of the 
    CAA, Congress established a system of state and federal cooperation. 
    EPA is required to establish the NAAQS, i.e., the level at which air 
    quality is determined to be protective of human health. However, the 
    States take the primary lead in determining the measures necessary to 
    attain and maintain the NAAQS. These measures are incorporated into the 
    SIP. The CAA requires EPA to approve a SIP submission that meets the 
    requirements of the CAA. If the State fulfills its obligations in 
    developing a SIP that meets the requirements of the CAA, EPA has no 
    authority to supplement or revise that plan with a federal 
    implementation plan. Because the States have submitted a Maintenance 
    Plan that complies with the CAA, EPA must approve the
    
    [[Page 27206]]
    
    Maintenance Plan under section 110(k)(3). Furthermore, since the States 
    have met the redesignation requirements to demonstrate that the air 
    quality meets the NAAQS, EPA believes the air quality is sufficient to 
    protect the public health and, therefore, EPA cannot reject the 
    redesignation request on this basis. Since the States submitted 
    Maintenance Plans and Redesignation Requests that comply with the Act, 
    and there is no issue about whether the States have the authority to 
    implement the measures included in the submission, EPA has no basis for 
    modifying the State's selection of the measures in the Maintenance 
    Plan.
        (4) Comment: The United Associated of Fitters and Apprentices, 
    Local #290 objected to the EPA approvals of the revisions to the Oregon 
    SIP because, under Oregon law, Local #290 has no legal standing to 
    represent the rights of their members in judicial proceedings involving 
    ODEQ permits. This comment asserts that EPA's delegation of CAA 
    enforcement, from EPA to Oregon ODEQ, ``is premised on ODEQ's allowing 
    individuals to exercise their constitutionally-granted representational 
    rights, for groups to which they belong, to appeal DEQ's decisions, 
    including but not limited to DEQ permits issued under the Clean Air 
    (and Clean Water) Acts.'' Because Local #290 believes that ODEQ does 
    not allow a group such as Local #290 to seek judicial review of a 
    permit issued by ODEQ, it vehemently objects to EPA granting any 
    further delegated authority to enforce the CAA and Clean Water Act. 
    Furthermore, Local 290 asks that EPA rescind any existing 
    delegations of CAA enforcement authority, unless and until ODEQ grants 
    groups in Oregon the legal standing to represent the rights of their 
    members in judicial proceedings involving ODEQ permits.
        Response: This comment is not relevant to the actions EPA is taking 
    in this notice. Title I of the CAA, which establishes requirements for 
    SIPs and designation actions, contains no provisions governing judicial 
    review of permits issued by a State. EPA finds that ODEQ has met the 
    public participation requirements of Title I of the CAA. Therefore, EPA 
    does not agree to delay its actions on the SIP revisions that are the 
    subject of this notice or to delay its redesignation to attainment of 
    the Pdx/Van O3 area for the reason cited by the commenter. 
    However, EPA is pursuing the matter of Oregon's judicial review in the 
    context of Title V of the CAA, which requires that a State provide 
    judicial review of its actions. For purposes of ODEQ's Title V program, 
    which EPA has approved, EPA will evaluate whether State law meets the 
    requirements of the CAA.
    
    III. Final Action
    
        EPA is redesignating to attainment the Portland, Oregon; and 
    Vancouver, Washington, interstate O3 area because ODEQ and 
    WDOE have demonstrated compliance with the requirements of section 
    107(d)(3)(E) for redesignation. EPA is approving the Portland and 
    Vancouver O3 Maintenance Plans as meeting the requirements 
    of the CAA, including the requirements set forth in EPA regulations and 
    guidance.
        EPA also is approving the 1990 O3 Emission Inventories, 
    changes to the New Source Review (NSR) programs, regulations 
    implementing the hybrid low enhanced I/M programs, an expanded vehicle 
    inspection boundary, minor Reasonably Available Control Technology 
    (RACT) rule changes (Vancouver only), Employee Commute Options rule 
    (Portland only), Voluntary Parking Ratio rule (Portland only), Plant 
    Site Emission Limits (PSEL) management rules (Portland only), and local 
    area source supporting rules.
        EPA notes that, as part of its SIP submission, Oregon and 
    Washington included adequate backup plans for contingencies to ensure 
    continued attainment of the NAAQS and to meet the emission reduction 
    targets of the submittals approved today. For example, the contingency 
    plans for both states provide assurances that contingency measures will 
    be adopted within 12 months after a violation of the NAAQS occurs and 
    implemented within a specified period of time. Similarly, if Oregon's 
    Voluntary Parking Ratio or the Public Education and Incentive programs 
    fail to achieve emission reductions equal to the target set in the 
    Maintenance Plan, ODEQ has furnished a commitment to adopt backup 
    measures by a date certain. EPA finds that there is adequate assurance 
    that the planned emission reductions will be achieved and they are 
    therefore approved for credit in the Maintenance Plan. Additional 
    regulations specific to Washington only and Oregon only are described 
    below.
    
    Washington
    
        The regulations EPA is approving now for the Vancouver, Washington, 
    portion are found in the following. EPA is approving only those changes 
    to SWAPCA's NSR rules that relate to the new maintenance area NSR 
    provisions and EPA will be taking action on the remaining portions of 
    the December 11, 1996, NSR submittal in a separate action.

        EPA also approves the Industrial Emissions Management Program 
    Regulations (OAR 340-030-0700 through -340-030-0740); Employee Commute 
    Options Program Regulations (OAR 340-030-0800 through -340-030-1080); 
    Voluntary Maximum Parking Ratios Program Regulations (OAR 340-030-1100 
    through -340-030-1190). The above three amendments to the OAR became 
    State-effective on August 14, 1996. The following three amendments 
    became State-effective on August 19, 1996: Definitions of Boundaries 
    (OAR 340-031-0500); Nonattainment Areas (OAR 340-031-0520); Maintenance 
    Areas (OAR 340-031-0530).
        EPA approves the amendment to Oregon's Motor Vehicle Inspection and 
    Maintenance Area Boundary (OAR 340-024-0301), effective August 12, 
    1996. EPA approves the Oregon I/M revisions to OAR 340-24-0100, -0300, 
    -0305, -0306, -0307, -0308, -0309, -0312, -0314 (with the exception of 
    all language in (4)(a) referring to a ``sixth hill extrapolation''), -
    0318, -0320, -0325, -0330, -0332, -0335, -0337, -0340, -0355, -0357, 
    and -0360, State effective on November 26, 1996. EPA also approves the 
    deletion of OAR 340-24-0310, -0315, and -0350, State effective on 
    November 26, 1996.
        During EPA's review of a SIP revision involving Oregon's statutory 
    authority, a problem was detected which affected the enforceability of 
    point source permit limitations. Even though the SIP does not contain 
    additional point source controls to attain the standard, existing and 
    federally approved point source emission limitations are relied upon to 
    maintain and demonstrate attainment with the O3 NAAQS. EPA 
    determined that, because the five-day advance notice provision required 
    by ORS.126(1) (1991) bars civil penalties from being imposed for 
    certain permit violations, ORS 468 fails to provide the adequate 
    enforcement authority the State must demonstrate to obtain SIP 
    approval, as specified in Section 110 of the CAA and 40 CFR 51.230. 
    Accordingly, the requirement to provide such notice would preclude 
    federal approval of a O3 nonattainment area SIP revision. 
    EPA notified Oregon of the deficiency. To correct the problem, the 
    Governor of Oregon signed into law new legislation amending ORS 468.126 
    on September 3, 1993. This amendment added paragraph 468.126(2)(e) 
    which provides that the five-day advance notice required by ORS 
    468.126(1) does not apply if the notice requirement will disqualify the 
    State's program from federal approval or delegation. ODEQ responded to 
    EPA's understanding of the application of 468.126(2)(e) and agreed 
    that, if federal statutory requirements preclude the use of the five-
    day advance notice provision, no advance notice will be required for 
    violations of SIP requirements contained in permits.
        Nothing in this action should be construed as permitting or 
    allowing or establishing a precedent for any future request for 
    revision to any SIP. Each request for revision to any SIP shall be 
    considered separately in light of specific technical, economic, and 
    environmental factors and in relation to relevant statutory and 
    regulatory requirements.
    
    IV. Administrative Requirements
    
    A. Executive Order 12866
    
        This action has been classified as a Table 3 action for signature 
    by the Regional Administrator under the procedures published in the 
    Federal Register on January 19, 1989, (54 FR 2214-2225), as revised by 
    a July 10, 1995, memorandum from Mary Nichols, Assistant Administrator 
    for Air and Radiation. The Office of Management and Budget (OMB) has 
    exempted this regulatory action from E.O. 12866 review.
    
    B. Regulatory Flexibility Act
    
        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 impact on a substantial number of small entities. Small 
    entities include small businesses, small not-for-profit
    
    [[Page 27208]]
    
    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, the 
    Administrator certifies that it does not have a significant impact on 
    any small entities affected. Moreover, due to the nature of the 
    Federal-State relationship under the CAA, preparation of a 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. 
    EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
        Redesignation of an area to attainment under section 107(d)(3)(E) 
    of the CAA does not impose any new requirements on small entities. 
    Redesignation is an action that affects the status of a geographical 
    area and does not impose any regulatory requirements on sources. The 
    Administrator certifies that the approval of the redesignation request 
    will not affect a substantial number of small entities.
    
    C. Unfunded Mandates
    
        Under Section 202 of the Unfunded Mandates Reform Act of 1995 
    (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
    must prepare a budgetary impact statement to accompany any proposed or 
    final rule that includes a Federal mandate that may result in estimated 
    costs to State, local, or tribal governments in the aggregate; or to 
    private sector, of $100 million or more. Under Section 205, EPA must 
    select the most cost-effective and least burdensome alternative that 
    achieves the objectives of the rule and is consistent with statutory 
    requirements. Section 203 requires EPA to establish a plan for 
    informing and advising any small governments that may be significantly 
    or uniquely impacted on by the rule.
        EPA has determined that the approval action promulgated does not 
    include a Federal mandate that may result in estimated costs of $100 
    million or more to either State, local, or tribal governments in the 
    aggregate, or to the private sector. This Federal action approves pre-
    existing requirements under State or local law, and imposes no new 
    requirements. Accordingly, no additional costs to State, local, or 
    tribal governments, or to the private sector, result from this action.
    
    D. Submission to Congress and the General Accounting Office
    
        Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business 
    Regulatory Enforcement Fairness Act of 1996, EPA submitted 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 
    General Accounting Office prior to publication of the rule in today's 
    Federal Register. This rule is not a ``major rule'' as defined by 5 
    U.S.C. 804(2).
    
    E. 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 18, 1997. 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).)
