    ACTION: Direct final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is conditionally approving a State Implementation Plan 
    (SIP) revision submitted by the State of Connecticut on June 24, 1998 
    and a commitment submitted November 13, 1998 to start on-board 
    diagnostic testing (OBD) by July 1, 2001. This revision conditionally 
    approves the Connecticut statewide enhanced inspection and maintenance 
    (I/M) program. The effect of this action is to conditionally approve 
    the State's I/M SIP revision which for the most part is approvable, but 
    which does not meet all EPA enhanced I/M program regulatory 
    requirements. Connecticut has committed to correcting these 
    deficiencies by July 1, 1999. EPA is also approving a request by the 
    Connecticut Department of Environmental Protection (CTDEP) on May 29, 
    1998 to redesignate the Connecticut portion of the New York-N. New 
    Jersey-Long Island carbon monoxide nonattainment area from 
    nonattainment to attainment for carbon monoxide (CO). EPA is approving 
    this request which establishes the Connecticut portion of this area as 
    attainment for carbon monoxide and requires the State to implement its 
    10 year maintenance plan that will insure that the area remains in 
    attainment. Under the Clean Air Act (CAA), section 107 as amended in 
    1990, designations can be revised if sufficient air quality data is 
    available to warrant such revisions. EPA is approving the Connecticut 
    request because it addresses the redesignation requirements set forth 
    in the CAA. This action is being taken under section 107 of the Clean 
    Air Act.
    
    DATES: This direct final rule is effective on May 10, 1999 without 
    further notice, unless EPA receives relevant adverse comment by April 
    9, 1999. If relevant adverse comment is received, EPA will publish a 
    timely withdrawal of the direct final rule in the Federal Register and 
    inform the public that the rule will not take effect.

    SUPPLEMENTARY INFORMATION:
    
    I. Background
    
    A. Clean Air Act Requirements for I/M
    
        The Clean Air Act, as amended in 1990 (CAA or Act), requires 
    certain States to revise and improve existing     I/M programs or 
    implement new ones. All ozone nonattainment areas classified as 
    moderate or worse must implement a basic or enhanced I/M program 
    depending upon its nonattainment classification, regardless of previous 
    requirements. In addition, Congress directed the EPA in section 
    182(a)(2)(B) to publish updated guidance for State   I/M programs, 
    taking into consideration findings of the Administrator's audits and 
    investigations of these programs. The States must then incorporate this 
    guidance into the SIP for all areas required by the Act to have an I/M 
    program. Metropolitan statistical areas with populations of 100,000 or 
    more that are within the Northeast Ozone Transport Region are required 
    to meet EPA guidance for enhanced I/M programs.
        Final full approval of the portions of the state's I/M SIP revision 
    subject to the conditions stated in this notice is still necessary 
    under section 110 and under section 182, 184 or 187 of the CAA.
    
    B. Rationale for CO Redesignation
    
        On November 2, 1998 EPA published a direct final rule in the 
    Federal Register approving the maintenance plan, carbon monoxide (CO) 
    redesignation, and emissions inventory for the Connecticut portion of 
    the New York--N. New Jersey--Long Island Area (62 FR 58637). This 
    action was meant to redesignate the southwest Connecticut moderate 
    carbon monoxide (CO) area to attainment. On December 2, 1998, EPA 
    received a comment on that action, which should have prevented the 
    direct final rule from taking effect. EPA is removing the amendments in 
    that action in a parallel document published elsewhere in today's 
    Federal Register. This action addresses the comment received and again 
    redesignates Southwest Connecticut to attainment for CO.
        In the November 2, 1998 document, EPA inaccurately stated that 
    Connecticut has a fully approved CO SIP. A fully approved CO 
    nonattainment SIP for this area must include a fully approved enhanced 
    I/M program. On December 2, 1998, EPA received a comment pointing out 
    that EPA has not fully approved Connecticut's enhanced I/M program and 
    inquiring as to the basis for EPA's redesignation in light of the 
    absence of a fully approved enhanced I/M program.1
    ---------------------------------------------------------------------------
    
        \1\ EPA also received a comment from the State of New Jersey 
    supporting the Connecticut redesignation and making certain 
    assertions about New Jersey's eligibility for redesignation and the 
    use of oxygenated fuels. EPA is taking no position in this notice on 
    New Jersey's eligibility for redesignation and the use of oxygenated 
    fuels in either New Jersey or Connecticut. The Clean Air Act 
    requires the sale of oxygenated fuels in areas that are located 
    within a CMSA in which a carbon monoxide nonattainment area with a 
    design value of 9.5 parts per million or greater, and that 
    requirement is not changed merely by the redesignation of such areas 
    to attainment. Although the Southwest Connecticut emission inventory 
    and maintenance plan EPA presented in its prior document (See 63 FR 
    58641 (Nov. 2, 1998)) did not include any emissions reductions from 
    the sale of oxygenated fuels, the applicability of the requirements 
    concerning the sale of oxygenated fuels in the southwest Connecticut 
    portion of the New York City consolidated metropolitan statistical 
    area will not be affected by the redesignation of southwest 
    Connecticut to attainment.
    ---------------------------------------------------------------------------
    
        A memorandum from John Calcagni, September 4, 1992, Procedures for 
    Processing Requests to Redesignate Areas to Attainment, states that 
    areas requesting redesignation to attainment must fully adopt rules and 
    programs that come due prior to the submittal of a complete 
    redesignation request. However, EPA is allowing a deminimis exception 
    to this policy in today's action. While all nonattainment area SIP 
    requirements that come due prior to the submission of the redesignation 
    request
    
    [[Page 12006]]
    
    remain applicable requirements, the EPA believes it appropriate, in 
    this instance, to allow a narrow exception to this policy with respect 
    to the conditional approval of the I/M program.
        In its approval of the redesignation to attainment for ozone of 
    Grand Rapids, Michigan, EPA formulated a limited exception to the 
    requirement that an area must have a fully approved SIP prior to 
    redesignation. 61 FR 31831, 31833, 31843-31847 (June 21, 1996). In that 
    action, EPA allowed redesignation where the area had not adopted nor 
    received approval for certain VOC RACT rules, accepting instead a 
    commitment to adopt and implement the RACT rules as contingency 
    measures in the maintenance plan, rather than require full adoption and 
    approval prior to redesignation. EPA allowed this exception based on a 
    combination of several factors: (1) The rules were not needed to bring 
    about attainment of the ozone standard in Grand Rapids; (2) the State 
    demonstrated maintenance without the implementation of these measures; 
    (3) the State placed other contingency measures in the maintenance plan 
    that would bring about greater emission reductions than the VOC RACT 
    rules would. 31833-31834. See also 61 FR 14526-14527 (April 2, 1996) 
    (proposed rulemaking on Grand Rapids). Moreover, the State would have 
    been able to have the RACT rules become a part of the contingency 
    measures upon approval of the redesignation, and thus the only 
    difference lay in having a commitment to adopt contingency measures 
    rather than fully adopted contingency measures. 31843-31844. EPA 
    concluded that ``this difference has no significant environmental 
    consequence and that it is permissible to approve the Grand Rapids 
    redesignation on this basis.'' 61 FR 14527.
        The Southwestern Connecticut redesignation presents a similar case 
    for an exception to the general policy that all SIP provisions must be 
    fully approved. In the case of southwestern Connecticut, EPA believes 
    that, as in Grand Rapids, a number of factors in combination justify an 
    approach similar to that taken with respect to Grand Rapids.
        First, as explained in the first direct final rule for this 
    redesignation, the modeling supporting Connecticut's redesignation 
    demonstrates that emission reductions from enhanced I/M are not needed 
    to attain the CO standard. Second, reductions from enhanced I/M are not 
    needed to maintain the CO standard during the maintenance period. 
    Third, the State has committed to implement enhanced I/M as a 
    contingency measure in their CO maintenance plan, as well as the low 
    emission vehicle program. Fourth, Connecticut remains obligated to 
    implement a fully enhanced I/M program under the Act based on the 
    state's status as an ozone nonattainment area. Indeed, Connecticut is 
    already implementing the enhanced I/M program in order to achieve 
    emissions reductions for the purposes of addressing ozone 
    nonattainment. Note that the enhanced I/M program only commenced 
    operation in January 1998. Therefore, any CO reductions achieved by the 
    enhanced program were not a factor in attaining the CO standard in 
    southwest Connecticut or elsewhere in this CO nonattainment area, 
    because the enhanced I/M program did not operate during the 1996-1997 
    years, two of the years when the entire area monitored air quality 
    attaining the CO standard. Nevertheless, Connecticut's operation of the 
    program gives EPA substantial assurance that the environmental benefit 
    of the enhanced I/M program will be achieved despite this minor 
    departure from Agency redesignation policy. Fifth, the deficiencies in 
    the Connecticut enhanced I/M program, while they must be corrected for 
    full approval, are not flaws in the program that substantially diminish 
    the level of emissions reductions the current program achieves as 
    compared with a fully approvable program. Finally, EPA is today 
    conditionally approving the enhanced I/M program into the SIP. 
    Connecticut has committed to meeting the conditions of EPA's approval 
    and correcting its program by July 1, 1999. Even if the State failed to 
    meet these conditions, EPA is providing that the conditional approval 
    will convert to a limited approval/limited disapproval of the enhanced 
    I/M program, so the emissions reductions from Connecticut's current 
    enhanced I/M program will remain enforceable under the SIP in the 
    unlikely event the State fails to meet its commitment to cure the I/M 
    program.
        For all these reasons, EPA has concluded that relying on a 
    conditional approval of Connecticut's enhanced I/M program for the 
    purposes of redesignating the southwest portion of the State to 
    attainment for CO is a deminimis departure from redesignation 
    requirements. In the context of this particular CO redesignation, the 
    difference between full and conditional approval has a trivial 
    environmental impact, if any.
        As in Grand Rapids, EPA believes that the difference between full 
    approval and the circumstances presented by Southwestern Connecticut 
    has no significant environmental consequence and that it is permissible 
    to approve the redesignation on this basis. Indeed, arguably 
    Connecticut's circumstances are even more persuasive than those in 
    Grand Rapids: the fact that the program has been substantially adopted 
    and is currently being implemented, and that Connecticut will remain 
    obligated after redesignation to implement an enhanced I/M program 
    based on its ozone nonattainment status, and the fact that EPA is 
    providing that its conditional approval will convert to a limited 
    approval to preserve the enforceability of the I/M program, all provide 
    even greater assurances that redesignation will not put at risk the 
    achievement of any significant environmental benefits.
    
    C. Background on Connecticut's I/M Program
    
        On June 24, 1998, Connecticut submitted an enhanced I/M SIP 
    revision to EPA, requesting action under the CAA of 1990. The official 
    submittal was made by the appropriate State officials, Mr. Jose O. 
    Salinas, Commissioner of Motor Vehicles, and Mr. Arthur J. Roche Jr., 
    Commissioner Environmental Protection, and was addressed to John 
    DeVillars, Regional Administrator, the appropriate EPA official in the 
    Region.
        The State of Connecticut has adopted legislation, at Sec. 14-164c 
    and Sec. 22a of the Connecticut General Statutes, enabling the 
    implementation of an enhanced I/M program.
        On March 26, 1998 and April 7, 1998, the Connecticut I/M 
    regulations were filed with the Secretary of State thereby making them 
    effective. The regulations call for implementation of a test-only 
    enhanced I/M program which started operation in January 1998, utilizing 
    new emission analyzers and dynamometers connected to a central computer 
    with final cut points being implemented in 2001.
        The program calls for biennial ASM2525 testing in test-only 
    contractor-operated facilities. The test equipment will be ASM 
    connected to a contractor operated central computer. The program 
    evaluation year is 2000.
    
    D. Analysis of the EPA I/M Regulation and CAA Requirements
    
        Based upon EPA's review of Connecticut's submittal, EPA believes 
    the State has complied with most but not all aspects of the CAA and the 
    I/M Rule. For those sections of the I/M rule identified below with 
    which the State has not yet fully complied, EPA is conditionally 
    approving the SIP since
    
    [[Page 12007]]
    
    the State has committed in the I/M SIP submittal to correct said 
    deficiencies by a date certain (July 1, 1999) within 1 year of EPA 
    approval.
        The State must correct these deficiencies by the date committed to 
    in the I/M SIP or the conditional approval will convert to a final 
    limited approval/limited disapproval under CAA section 110(k)(4). In 
    that event, EPA would issue a letter to notify the State that the 
    conditions had not been met and that the approval had converted to a 
    limited approval/limited disapproval, starting an 18 month clock prior 
    to imposing sanctions under CAA Section 179.
    
    Applicability--40 CFR 51.350
    
        Sections 182(c)(3) and 184(b)(1)(A) of the Act and 40 CFR 51.350(a) 
    require all states in the Ozone Transport Region (OTR) which contain 
    Metropolitan Statistical Areas (MSAs) or parts thereof with a 
    population of 100,000 or more to implement an enhanced I/M program. 
    Connecticut is part of the OTR and contains the following MSAs or parts 
    thereof with a population of 100,000 or more: Hartford-New Britain-
    Middletown, CMSA, New York-Northern New Jersey-Long Island, NY-NJ-CT 
    CMSAs.
        Connecticut is also classified as a serious ozone nonattainment 
    area for the greater Connecticut Area and a severe ozone nonattainment 
    area for the New York-New Jersey-Long Island area and is required to 
    implement an enhanced I/M program per section 182(c)(3) of the CAA and 
    40 CFR 51.350(a)(2). Although the New Haven/Meriden/Waterbury area and 
    the Hartford-New Britain-Middletown area are no longer CO nonattainment 
    areas, a basic CO I/M program is part of the CO Maintenance Plan and an 
    enhanced I/M program is part of the CO Contingency Plan for these 
    areas. This is also true for the Connecticut portion of the New York-N. 
    New Jersey-Long Island area redesignation to attainment, which will 
    become effective May 10, 1999 as described earlier in this notice.
        Although under the requirements of the Clean Air Act, not all 
    counties in Connecticut would be subject to I/M program requirements, 
    the Connecticut I/M regulation requires that the enhanced I/M program 
    be implemented statewide. As stated in the State submittal, the 
    Connecticut I/M legislative authority in section 14-164c, and section 
    22a of the Connecticut General Statutes provides the authority to 
    establish a statewide enhanced program. EPA finds that the geographic 
    applicability requirements are satisfied. The federal I/M rule requires 
    that the state program not terminate until it is no longer necessary. 
    EPA interprets the federal rule as stating that a SIP which does not 
    sunset prior to the attainment deadline for each applicable area 
    satisfies this requirement. The Connecticut submittal does not address 
    the length of time the program will be in effect. The program must 
    continue past the attainment dates for all applicable nonattainment 
    areas in Connecticut. In the absence of a sunset date, EPA interprets 
    the SIP submittal as requiring the I/M program to continue 
    indefinitely, and approves the program on this basis. This unlimited 
    term of the program will be federally enforceable as a requirement of 
    the SIP.
    
    Enhanced I/M Performance Standard--40 CFR 51.351
    
        The enhanced I/M program must be designed and implemented to meet 
    or exceed a minimum performance standard, which is expressed as 
    emission levels in area-wide average grams per mile (gpm) for certain 
    pollutants. The performance standard shall be established using local 
    characteristics, such as vehicle age mix and local fuel controls, and 
    the following model I/M program parameters: network type, start date, 
    test frequency, model years, vehicle type coverage, exhaust emission 
    test type, emission standards, emission control device, evaporative 
    system function checks, stringency, waiver rate, compliance rate and 
    evaluation date. The emission levels achieved by the state's program 
    design shall be calculated using the most current version, at the time 
    of submittal, of the EPA mobile source emission factor model. At the 
    time of the Connecticut submittal, the most current version was 
    MOBILE5b. Areas shall meet the performance standard for the pollutants 
    which cause them to be subject to enhanced I/M requirements. In the 
    case of ozone nonattainment areas, the performance standard must be met 
    for both nitrogen oxides (NOX) and hydrocarbons (HC). In the 
    case of carbon monoxide areas, the performance standard must be met for 
    CO. This Connecticut submittal must meet the enhanced I/M performance 
    standard statewide for HC and NOx and in the Connecticut portion of the 
    New York-Northern New Jersey and Long Island CO nonattainment area for 
    CO.
        EPA published requirements for on-board diagnostic (OBD) testing in 
    inspection and maintenance programs in the Federal Register at 61 FR 
    40940 on August 6, 1996 and extended the required date until January 1, 
    2001 in the Federal Register at 63 FR 24429 on May 4, 1998. States were 
    required to submit a SIP by August 6, 1998 committing to begin OBD 
    testing in accordance with EPA regulations by January 1, 2001.
        The Connecticut submittal includes the following program design 
    parameters:
    
    Network type--test-only
    Start date--1998
    Test frequency--biennial
    Model year/ vehicle type coverage--1981+, light and heavy duty up to 
    10,000 GVW, gasoline
    Exhaust emission test type--ASM2525
    Emission standards--See Regulations of Connecticut State Agencies 
    Section 22a-174-279(c) and (d)
    Emission control device check--yes (catalytic converters)
    Evaporative system function checks--81+ (gas cap only)
    Stringency (pre-1981 failure rate)--20%
    Waiver rate--3%
    Compliance rate--96%
    Evaluation date(s)--2000
    
        Connecticut has submitted modeling demonstrations using the EPA 
    computer model MOBILE5b showing that the enhanced performance standard 
    reductions will be met in 2000 for NOx, HC, and CO.
        In the modeling, Connecticut has claimed full credit for mechanic 
    training. Repair shops are licensed by the Department of Motor Vehicles 
    in Connecticut. Either by complaints or a high rate of retest failures 
    shops are identified for nonroutine visits to identify problems. There 
    will be extensive training and support network provided for mechanics 
    provided by the educational community, DMV and the contractor. Only 
    work done by licensed shops can be counted toward a waiver. Based on 
    this, the state has taken full credit for mechanic training. Since EPA 
    has no conflicting data to refute the State's claim at this time, the 
    use of full credit for mechanic training will be approved at this time, 
    subject to reconsideration in connection with final full approval of 
    the entire program subsequent to the July 1, 1999 submittal to satisfy 
    conditions in this document. EPA is studying the technician training 
    credit available, and expects to have further guidance available prior 
    to the July 1, 1999 date for submittal by Connecticut of a revision to 
    meet the conditions specified in this document.
        On November 13, 1998, Connecticut submitted a SIP revision which 
    committed to start OBD testing meeting EPA requirements by January 1, 
    2001. This submittal meets the requirements set forth in the I/M 
    regulations for OBD at this time.
        EPA is conditionally approving the Connecticut program at this time
    
    [[Page 12008]]
    
    consistent with the requirements of the CAA. If the State cannot meet 
    the high enhanced I/M performance standard, the State may demonstrate 
    compliance with the low enhanced performance standard established in 40 
    CFR 51.351(g). That section provides that states may select the low 
    enhanced performance standard if they have an approved SIP for 
    reasonable further progress in 1996, commonly known as a 15 percent 
    reduction SIP or 15 percent plan. EPA's approval of Connecticut's 15 
    percent plan is published elsewhere in today's Federal Register as a 
    direct final rule. The approval of this I/M program is conditioned on 
    the approval of Connecticut's 15 percent plan. In the event that 
    effective date of the 15 percent plan is delayed, EPA will 
    correspondingly delay the effective date of the I/M plan and the CO 
    redesignation in this document.
        Calculations done by the State for a revised 15% plan indicate that 
    the State can achieve the needed 15% reduction without the high 
    enhanced standard utilizing the ASM credits The State has shown that 
    the program meets the ``low enhanced I/M performance standard'' in 
    2000.
    
    Network Type and Program Evaluation--40 CFR 51.353
    
        The enhanced program shall include an ongoing evaluation to 
    quantify the emission reduction benefits of the program, and to 
    determine if the program is meeting the requirements of the Act and the 
    federal I/M regulation. The SIP shall include details on the program 
    evaluation and shall include a schedule for submittal of biennial 
    evaluation reports and the legal authority enabling the evaluation 
    program.
        The program evaluation requirements of EPA's I/M rule were 
    postponed in the Federal Register on January 9, 1998, (63 FR 1362) in 
    order for EPA to evaluate alternate methods for states to meet this 
    requirement. On January 9, 1998, EPA required states to submit program 
    evaluation requirements by November 30, 1998. In its June 15, 1998 
    submittal, the state committed to meet the program evaluation 
    requirements of 40 CFR 51.353. EPA interprets this commitment to mean 
    that Connecticut will submit program evaluation requirements consistent 
    with EPA's January 9, 1998 guidance by July 1, 1999. This part of the 
    submittal does not meet the requirements of this section set forth in 
    the federal I/M rule and this is a SIP deficiency. The State has 
    committed to correct this SIP deficiency by a date certain (July 1, 
    1999) within one year of conditional approval of this submittal.
    
    Adequate Tools and Resources--40 CFR 51.354
    
        The federal regulation requires the state to demonstrate that 
    adequate funding of the program is available. A portion of the test fee 
    or separately assessed per vehicle fee shall be collected, placed in a 
    dedicated fund and used to finance the program. Alternative funding 
    approaches are acceptable if it is demonstrated that the funding can be 
    maintained. Reliance on funding from the state or local General Fund is 
    not acceptable unless doing otherwise would be a violation of the 
    state's constitution. The SIP shall include a detailed budget plan 
    which describes the source of funds for personnel, program 
    administration, program enforcement, and purchase of equipment. The SIP 
    shall also detail the number of personnel dedicated to the quality 
    assurance program, data analysis, program administration, enforcement, 
    public education and assistance and other necessary functions.
        The State has provided for a dedicated fund for the program, and 
    has submitted resource allocations and budgets. The submittal meets the 
    requirements of this section set forth in the federal I/M rule and is 
    approvable.
    
    Test Frequency and Convenience--40 CFR 51.355
    
        The enhanced I/M performance standard assumes an annual test 
    frequency; however, other schedules may be approved if the performance 
    standard is achieved. The SIP shall describe the test year selection 
    scheme, how the test frequency is integrated into the enforcement 
    process and shall include the legal authority, regulations or contract 
    provisions to implement and enforce the test frequency. The program 
    shall be designed to provide convenient service to the motorist by 
    ensuring short wait times, short driving distances and regular testing 
    hours.
        The Connecticut program will require biennial testing for 1981 and 
    newer vehicles and annual testing of 1968-1980 vehicles in a test-only 
    network. The program meets the performance standard with this level of 
    testing. The state has expanded the network to accommodate a longer 
    enhanced test. The contractor is required to provide convenient 
    locations and reasonable wait times. Legal authority for these 
    requirements is found in Connecticut General Statutes (C.G.S.) section 
    14-164c(c) and regulations of Connecticut State Agencies (R.C.S.A.) 
    section 14-164c-2a(a). This part of the submittal meets all applicable 
    requirements of this section as set forth in the federal I/M rule and 
    is part of the basis for conditional approval of the Connecticut I/M 
    SIP.
    
    Vehicle Coverage--40 CFR 51.356
    
        The performance standard for enhanced I/M programs assumes coverage 
    of all 1968 and later model year light duty vehicles and light duty 
    trucks up to 8,500 pounds GVWR, and includes vehicles operating on all 
    fuel types. Other levels of coverage may be approved if the necessary 
    emission reductions are achieved. Vehicles registered or required to be 
    registered within the I/M program area boundaries and fleets primarily 
    operated within the I/M program area boundaries and belonging to the 
    covered model years and vehicle classes comprise the subject vehicles. 
    Fleets may be officially inspected outside of the normal I/M program 
    test facilities, if such alternatives are approved by the program 
    administration, but shall be subject to the same test requirements 
    using the same quality control standards as non-fleet vehicles and 
    shall be inspected in the same type of test network as other vehicles 
    in the state, according to the requirements of 40 CFR 51.353(a).
        The federal I/M regulation requires that the SIP shall include the 
    legal authority necessary to implement and enforce the vehicle coverage 
    requirement, a detailed description of the number and types of vehicles 
    to be covered by the program and a plan for how those vehicles are to 
    be identified including vehicles that are routinely operated in the 
    area but may not be registered in the area, and a description of any 
    special exemptions including the percentage and number of vehicles to 
    be impacted by the exemption. Such exemptions shall be accounted for in 
    the emissions reduction analysis.
        EPA is not requiring states to implement section 40 CFR 
    51.356(a)(4) dealing with federal installations within I/M areas at 
    this time. The Department of Justice has recommended to EPA that this 
    regulation be revised since it appears to grant states authority to 
    regulate federal installations in circumstances where the federal 
    government has not waived sovereign immunity. It would not be 
    appropriate to require compliance with this regulation if it is not 
    constitutionally authorized. EPA will be revising this provision in the 
    future and will review state I/M SIPs with respect to this issue when 
    this new rule is final.
        The State program proposes to test 1968 and newer light and heavy 
    duty vehicles up to 10,000 lbs. The
    
    [[Page 12009]]
    
    Connecticut submittal contains a detailed description of the number and 
    types of vehicles included in the program. See June 15, 1998, state 
    submittal at p. 8 and Apps. 7 and 8. There are no special provisions 
    for fleet testing at this time. All vehicles must be tested at 
    contractor operated stations. Legal authority for these requirements is 
    found in C.G.S. section 14-164c(c) and R.C.S.A. section 14-164c-2a(a).
        This part of the submittal meets all applicable requirements of 
    this section as set forth in the federal I/M rule and is part of the 
    basis for conditional approval of the Connecticut I/M SIP.
    
    Test Procedures and Standards--40 CFR 51.357
    
        Written test procedures and pass/fail standards shall be 
    established and followed for each model year and vehicle type included 
    in the program. Test procedures and standards are detailed in 40 CFR 
    51.357 and in the EPA documents entitled ``High-Tech
    I/M Test Procedures, Emission Standards, Quality Control Requirements, 
    and Equipment Specifications,'' EPA-AA-EPSD-IM-93-1, dated April 1994 
    and ``Acceleration Simulation Mode Test Procedures, Emission Standards, 
    Quality Control Requirements, and Equipment Specifications,'' EPA-AA-
    RSPD-IM-96-2, dated July 1996. The federal I/M regulation also requires 
    vehicles that have been altered from their original certified 
    configuration (i.e. engine or fuel switching) to be subject to the 
    requirements of Sec. 51.357(d).
        Connecticut is using an Acceleration Simulation Mode Test (ASM2525) 
    and has adopted the EPA test procedures and standards. This part of the 
    submittal meets the requirements of this section as set forth in the 
    federal I/M rule and is part of the basis for conditional approval of 
    the Connecticut I/M SIP.
    
    Test Equipment--40 CFR 51.358
    
        Computerized test systems are required for performing any 
    measurement on subject vehicles. The federal I/M regulation requires 
    that the state SIP submittal include written technical specifications 
    for all test equipment used in the program. The specifications shall 
    describe the emission analysis process, the necessary test equipment, 
    the required features, and written acceptance testing criteria and 
    procedures.
        Connecticut is using ASM specifications for test equipment to be 
    used in the program and a system which will utilize the latest 
    computerized equipment. Connecticut has fully explained its 
    specifications in its submittal. This part of the submittal meets all 
    applicable requirements of this section as set forth in the federal I/M 
    rule and is part of the basis for conditional approval of the 
    Connecticut I/M SIP.
    
    Quality Control--40 CFR 51.359
    
        Quality control measures shall insure that emission measurement 
    equipment is calibrated and maintained properly, and that inspection, 
    calibration records, and control charts are accurately created, 
    recorded and maintained.
        The Connecticut submittal includes a portion of the inspection 
    agreement which describes and establishes detailed quality control 
    measures for the emission measurement equipment, and record keeping 
    requirements. This part of the submittal meets all applicable 
    requirements of this section as set forth in the federal I/M rule and 
    is part of the basis for conditional approval of the Connecticut I/M 
    SIP.
    
    Waivers and Compliance Via Diagnostic Inspection--40 CFR 51.360
    
        The federal I/M regulation allows for the issuance of a waiver, 
    which is a form of compliance with the program requirements that allows 
    a motorist to comply without meeting the applicable test standards. For 
    enhanced I/M programs, an expenditure of at least $450 in repairs, 
    adjusted annually to reflect the change in the Consumer Price Index 
    (CPI) as compared to the CPI for 1989, is required by statute in order 
    to qualify for a waiver. Waivers can only be issued after a vehicle has 
    failed a retest performed after all qualifying repairs have been made. 
    Any available warranty coverage must be used to obtain repairs before 
    expenditures can be counted toward the cost limit. Tampering related 
    repairs shall not be applied toward the cost limit. Repairs must be 
    appropriate to the cause of the test failure. Repairs for 1980 and 
    newer model year vehicles must be performed by a recognized repair 
    technician. The federal regulation allows for compliance via a 
    diagnostic inspection after failing a retest on emissions and requires 
    quality control of waiver issuance. The SIP must set a maximum waiver 
    rate and must describe corrective action that would be taken if the 
    waiver rate exceeds that committed to in the SIP.
        Connecticut has provided for a waiver program for 1981 and later 
    vehicles (the portion of the fleet used to show achievement of the 
    enhanced performance standard) which meets the requirements of the I/M 
    rule with one exception.
        The date for compliance with the $450 adjusted waiver cost 
    requirement is beyond the January 1, 2000 deadline established by the 
    I/M rule. This part of the submittal does not meet the requirements of 
    this section set forth in the federal I/M rule and this is a SIP 
    deficiency. The State has committed to correct this major deficiency by 
    a date certain (July 1, 1999) within one year of conditional approval 
    of this submittal. The State has committed to a waiver rate in practice 
    equal to or lower than three percent. If the rate is higher, the State 
    will implement corrective strategies including ceasing waivers for 
    vehicles under six years of age, raising minimum expenditure limits, 
    and limiting waivers to once every four years for any one vehicle. June 
    15, 1998 State submittal at page 14.
    
    Motorist Compliance Enforcement--40 CFR 51.361
    
        The federal regulation requires that compliance shall be ensured 
    through the denial of motor vehicle registration in enhanced I/M 
    programs unless an exception for use of an existing alternative is 
    approved. An enhanced
    I/M area may use either sticker-based enforcement programs or computer-
    matching programs if either of these programs were used in the existing 
    program, which was operating prior to passage of the 1990 Clean Air Act 
    Amendments, and it can be demonstrated that the alternative has been 
    more effective than registration denial. The SIP shall provide 
    information concerning the enforcement process, legal authority to 
    implement and enforce the program, and a commitment to a compliance 
    rate to be used for modeling purposes and to be maintained in practice.
        The State is planning on utilizing a sticker system for visible 
    evidence of compliance, but registration will be suspended or not 
    renewed for noncompliance. Noncomplying vehicles will be identified 
    within 14 days of the required inspection date and notified to comply. 
    This will be done with a computer matching program run by the 
    contractor. Registration suspension will take place for noncompliance 
    within 90 days. The Connecticut SIP submittal uses a 96% compliance 
    rate in the performance standard modeling demonstration and the State 
    has committed to it in practice. Connecticut has also described what 
    other measures will be used to achieve this compliance rate if it drops 
    below 96%. Legal authority for these requirements is found in C.G.S. 
    section 14-164c(a) and (j) and R.C.S.A. section 14-164-17a. This part 
    of the submittal meets all applicable requirements of this section as 
    set forth in the federal I/M rule and
    
    [[Page 12010]]
    
    is part of the basis for conditional approval of the Connecticut I/M 
    SIP.
    
    Motorist Compliance Enforcement Program Oversight--40 CFR 51.362
    
        The federal I/M regulation requires that the enforcement program 
    shall be audited regularly and shall follow effective program 
    management practices, including adjustments to improve operation when 
    necessary. The SIP shall include quality control and quality assurance 
    procedures to be used to insure the effective overall performance of 
    the enforcement system. An information management system shall be 
    established which will characterize, evaluate and enforce the program.
        Connecticut has described in the SIP an outline of a program which 
    could meet the requirements of this section, however there is not 
    enough detailed information to determine whether the requirements are 
    met. This is a SIP deficiency which Connecticut must correct by a date 
    certain within one year of final conditional approval. The State has 
    committed in the I/M SIP to submit a plan to address these requirements 
    in more detail by July 1, 1999.
    
    Quality Assurance--40 CFR 51.363
    
        An ongoing quality assurance program shall be implemented to 
    discover, correct and prevent fraud, waste, and abuse in the program. 
    The program shall include covert and overt performance audits of the 
    inspectors, audits of station and inspector records, equipment audits, 
    and formal training of all state I/M enforcement officials and 
    auditors. A description of the quality assurance program which includes 
    written procedure manuals on the above discussed items must be 
    submitted as part of the SIP.
        Connecticut has described a program which addressed these 
    requirements in the SIP submittal. However, the written procedures 
    manuals, have not yet been developed. The state has committed to submit 
    these by July 1, 1999. This part of the submittal does not meet the 
    requirements of this section as set forth in the federal I/M rule 
    however, the State has committed in the I/M SIP to revise this section 
    by a date certain (July 1, 1999) within one year of final conditional 
    approval.
    
    Enforcement Against Contractors, Stations and Inspectors--40 CFR 51.364
    
        Enforcement against licensed stations, contractors and inspectors 
    shall include swift, sure, effective, and consistent penalties for 
    violation of program requirements. The federal I/M regulation requires 
    the establishment of minimum penalties for violations of program rules 
    and procedures which can be imposed against stations, contractors and 
    inspectors. The legal authority for establishing and imposing 
    penalties, civil fines, license suspensions and revocations must be 
    included in the SIP. State quality assurance officials shall have the 
    authority to temporarily suspend station and/or inspector licenses 
    immediately upon finding a violation that directly affects emission 
    reduction benefits, unless constitutionally prohibited. An official 
    opinion explaining any state constitutional impediments to immediate 
    suspension authority must be included in the submittal. The SIP shall 
    describe the administrative and judicial procedures and 
    responsibilities relevant to the enforcement process, including which 
    agencies, courts and jurisdictions are involved, who will prosecute and 
    adjudicate cases and the resources and sources of those resources which 
    will support this function.
        A detailed description of this part of the program including 
    minimum penalties and statutory suspension authority was submitted. See 
    June 15, 1998 state submittal at p. 22 and C.G.S. section 14-164c(e). 
    But Connecticut did not provide a description of administrative and 
    judicial procedures and responsibilities. Connecticut has in the I/M 
    SIP submittal committed to submit this information by a date certain 
    (July 1, 1999) within one year of conditional approval of the SIP.
    
    Data Collection--40 CFR 51.365
    
        Accurate data collection is essential to the management, evaluation 
    and enforcement of an I/M program. The federal I/M regulation requires 
    data to be gathered on each individual test conducted and on the 
    results of the quality control checks of test equipment required under 
    40 CFR 51.359.
        The Connecticut SIP provides a commitment to meet all of the data 
    collection requirements and has listed all the required data which will 
    be collected. This part of the submittal meets all applicable 
    requirements of this section set forth in the federal I/M rule and is 
    part of the basis for conditional approval of the Connecticut I/M SIP.
    
    Data Analysis and Reporting--40 CFR 51.366
    
        Data analysis and reporting are required to allow for monitoring 
    and evaluation of the program by the state and EPA. The federal I/M 
    regulation requires annual reports to be submitted which provide 
    information and statistics and summarize activities performed for each 
    of the following programs: testing, quality assurance, quality control 
    and enforcement. These reports are to be submitted by July and shall 
    provide statistics for the period of January to December of the 
    previous year. A biennial report shall be submitted to EPA which 
    addresses changes in program design, regulations, legal authority, 
    program procedures and any weaknesses in the program found during the 
    two year period and how these problems will be or were corrected.
        The Connecticut has committed to meet all of the data analysis and 
    reporting requirements of this section. The contractor will be required 
    to meet most of these requirements and submit them to the state, and 
    the state will submit the reports to EPA as required. This part of the 
    submittal meets all applicable requirements of this section as set 
    forth in the federal I/M rule and is part of the basis for conditional 
    approval of the Connecticut I/M SIP.
    
    Inspector Training and Licensing or Certification--40 CFR 51.367
    
        The federal I/M regulation requires all inspectors to be formally 
    trained and licensed or certified to perform inspections.
        The Connecticut I/M SIP requires training and certification of 
    inspectors as required in the I/M rule. This portion of the submittal 
    meets all applicable requirements of this section of the federal I/M 
    rule and is part of the basis for conditional approval of the 
    Connecticut I/M SIP.
    
    Public Information and Consumer Protection--40 CFR 51.368
    
        The federal I/M rule requires the SIP to include public information 
    and consumer protection programs. The Connecticut inspection program 
    has an existing public awareness and consumer protection plan, however, 
    it does not meet all the requirements of this section. The State has 
    committed in the I/M SIP to submit by a date certain (July 1, 1999) 
    additional information to show compliance with all aspects of this 
    section.
    
    Improving Repair Effectiveness--40 CFR 51.369
    
        Effective repairs are the key to achieving program goals. The 
    federal regulation requires states to take steps to ensure that the 
    capability exists in the repair industry to repair vehicles. The SIP 
    must include a description of the technical assistance program to be 
    implemented, a description of the procedures and criteria to be used in 
    meeting the performance monitoring requirements required in the federal
    
    [[Page 12011]]
    
    regulation, and a description of the repair technician training 
    resources available in the community. Connecticut has included all of 
    these required elements in its SIP submittal. See June 15, 1998 State 
    submittal at pp. 28-29.
        This part of the submittal meets all applicable requirements of 
    this section set forth in the federal I/M rule and is part of the basis 
    for conditional approval of the Connecticut I/M SIP.
    
    Compliance With Recall Notices--40 CFR 51.370
    
        The federal regulation requires the states to establish methods to 
    ensure that vehicles that are subject to enhanced I/M and are included 
    in a emission related recall receive the required repairs prior to 
    completing the emission test and/or renewing the vehicle registration.
        Most of the requirements of this section are met by the Connecticut 
    submittal, however, the requirement for a quality assurance plan for 
    this section is not addressed. The state has committed in the I/M SIP 
    to submit by a date certain (July 1, 1999) a quality assurance plan for 
    this section meeting the requirements of this section.
    
    On-road Testing--40 CFR 51.371
    
        On-road testing is required in enhanced I/M areas. The use of 
    either remote sensing devices (RSD) or roadside pullovers including 
    tailpipe emission testing can be used to meet the federal regulations. 
    The program must include on-road testing of 0.5% of the subject fleet 
    or 20,000 vehicles, whichever is less, in the nonattainment area or the 
    I/M program area. Motorists that have passed an emission test and are 
    found to be high emitters as a result of an on-road test shall be 
    required to pass an out-of-cycle test.
        The Connecticut SIP submittal outlines an on-road testing program 
    which could meet the requirements of the federal I/M rule. More detail 
    is needed to determine if all of the requirements of this section will 
    be met. The State in the I/M SIP submittal has committed to submit by a 
    date certain (July 1, 1999) an on-road testing program meeting the 
    requirements of this section.
    
    II. Final Action
    
        EPA is conditionally approving the enhanced I/M program SIP 
    revision submitted by the State of Connecticut on June 24, 1998 and 
    November 13, 1998 as revisions to the SIP. The State must submit to EPA 
    by July 1, 1999 a revision to the deficiencies described in detail 
    above to satisfy the requirements of the following sections of EPA's 
    enhanced I/M regulation: Network Type and Program Evaluation--40 CFR 
    51.353, Waivers and Compliance Via Diagnostic Inspection--40 CFR 
    51.360, Motorist Compliance Enforcement Program Oversight--40 CFR 
    51.362, Quality Assurance--40 CFR 51.363, Enforcement Against 
    Contractors, Stations and Inspectors--40 CFR 51.364, Public Information 
    and Consumer Protection--40 CFR 51.368, Compliance with Recall 
    Notices--40 CFR 51.370, and On-road Testing--40 CFR 51.371. If the 
    State fails to do so, this approval will convert to a limited approval 
    and limited disapproval on that date. EPA will notify the State by 
    letter that this action has occurred. At that time, the I/M program 
    will remain an enforceable part of the Connecticut SIP, but it will be 
    disapproved for the purposes of meeting CAA section 182 (c)(3)(C). EPA 
    subsequently will publish a document in the Federal Register notifying 
    the public that the conditional approval automatically converted to a 
    limited approval and limited disapproval. If the State meets its 
    commitment, within the applicable time frame, the conditionally 
    approved submission will remain a part of the SIP until EPA takes final 
    action approving or disapproving the new submittal. If EPA disapproves 
    the new submittal or portions of it, the conditionally approved 
    portions will be disapproved at that time. If EPA approves the 
    submittal, the inspection and maintenance program will be fully 
    approved in its entirety and replace the conditionally approved program 
    in the SIP.
        If the conditional approval is converted to a limited approval and 
    limited disapproval, such action will trigger EPA's authority to impose 
    sanctions under section 110(m) and 179 of the CAA at the time EPA 
    issues the final disapproval or on the date EPA notifies the State that 
    it has failed to meet its commitment. In the latter case, EPA will 
    notify the State by letter that the conditional approval has been 
    converted to a limited approval and limited disapproval and that EPA's 
    sanctions authority has been triggered. In addition, the final 
    disapproval triggers the federal implementation plan (FIP) requirement 
    under section 110(c). In any case, the I/M program would remain in the 
    SIP pursuant to this limited approval for the purposes of strengthening 
    the SIP.
        EPA is approving the southwest Connecticut CO redesignation because 
    the State has addressed compliance with the requirements of section 
    107(d)(3)(E) for redesignation and EPA is approving the maintenance 
    plan because it addresses the requirements set forth in section 175A of 
    the CAA. This only applies to the Connecticut Portion of the New York--
    N. New Jersey--Long Island Area. The New York and New Jersey portions 
    of the CO nonattainment area will remain designated nonattainment until 
    such time that redesignation requests are submitted and approved by EPA 
    for those states. Furthermore, nothing in this action should be 
    interpreted as a formal action on the part of EPA which would affect in 
    any way any area within the New York--Northern New Jersey--Long Island 
    carbon monoxide nonattainment area, except for the southwest 
    Connecticut portion of that area.
        EPA is publishing this rule without prior proposal because the 
    Agency views this as a noncontroversial amendment and anticipates no 
    adverse comments. However, in the proposed rules section of this 
    Federal Register publication, EPA is publishing a separate document 
    that will serve as the proposal to approve the SIP revision should 
    relevant adverse comments be filed. This action will be effective May 
    10, 1999 without further notice unless the Agency receives relevant 
    adverse comments by April 9, 1999.
        If the EPA receives such comments, then EPA will publish a document 
    withdrawing the final rule and informing the public that the rule will 
    not take effect. All public comments received will then be addressed in 
    a subsequent final rule based on the proposed rule. The EPA will not 
    institute another comment period on this action. Any parties interested 
    in commenting should do so at this time. If no such comments are 
    received, the public is advised that this rule will be effective on May 
    10, 1999 and no further action will be taken on the proposed rule.
        EPA's conditional approval of the I/M program depends on the 
    approval of the 15 percent plan being approved elsewhere in today's 
    Federal Register. In the event that the 15 percent plan approval is 
    withdrawn, EPA will correspondingly withdraw this I/M program 
    conditional approval and the CO redesignation request.
    
    III. Administrative Requirements
    
    A. Executive Order 12866
    
        The Office of Management and Budget (OMB) has exempted this 
    regulatory action from Executive Order (E.O.) 12866, entitled 
    ``Regulatory Planning and Review.''
    
    [[Page 12012]]
    
    B. Executive Order 12875
    
        Under E.O. 12875, EPA may not issue a regulation that is not 
    required by statute and that creates a mandate upon a state, local, or 
    tribal government, unless the Federal government provides the funds 
    necessary to pay the direct compliance costs incurred by those 
    governments, or EPA consults with those governments. If EPA complies by 
    consulting, Executive Order 12875 requires EPA to provide to the Office 
    of Management and Budget a description of the extent of EPA's prior 
    consultation with representatives of affected state, local, and tribal 
    governments, the nature of their concerns, copies of written 
    communications from the governments, and a statement supporting the 
    need to issue the regulation. In addition, E.O. 12875 requires EPA to 
    develop an effective process permitting elected officials and other 
    representatives of state, local, and tribal governments ``to provide 
    meaningful and timely input in the development of regulatory proposals 
    containing significant unfunded mandates.''
        Today's rule does not create a mandate on state, local or tribal 
    governments. The rule does not impose any enforceable duties on these 
    entities. Accordingly, the requirements of section 1(a) of E.O. 12875 
    do not apply to this rule.
    
    C. Executive Order 13045
    
        Protection of Children from Environmental Health Risks and Safety 
    Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) is 
    determined to be ``economically significant'' as defined under E.O. 
    12866, and (2) concerns an environmental health or safety risk that EPA 
    has reason to believe may have a disproportionate effect on children. 
    If the regulatory action meets both criteria, the Agency must evaluate 
    the environmental health or safety effects of the planned rule on 
    children, and explain why the planned regulation is preferable to other 
    potentially effective and reasonably feasible alternatives considered 
    by the Agency.
        This rule is not subject to E.O. 13045 because it is not 
    economically significant and does not involve decisions intended to 
    mitigate environmental health or safety risks.
    
    D. Executive Order 13084
    
        Under E.O. 13084, EPA may not issue a regulation that is not 
    required by statute, that significantly affects or uniquely affects the 
    communities of Indian tribal governments, and that imposes substantial 
    direct compliance costs on those communities, unless the Federal 
    government provides the funds necessary to pay the direct compliance 
    costs incurred by the tribal governments, or EPA consults with those 
    governments. If EPA complies by consulting, Executive Order 13084 
    requires EPA to provide to the Office of Management and Budget, in a 
    separately identified section of the preamble to the rule, a 
    description of the extent of EPA's prior consultation with 
    representatives of affected tribal governments, a summary of the nature 
    of their concerns, and a statement supporting the need to issue the 
    regulation. In addition, Executive Order 13084 requires EPA to develop 
    an effective process permitting elected officials and other 
    representatives of Indian tribal governments ``to provide meaningful 
    and timely input in the development of regulatory policies on matters 
    that significantly or uniquely affect their communities.''
        Today's rule does not significantly or uniquely affect the 
    communities of Indian tribal governments. This action does not involve 
    or impose any requirements that affect Indian Tribes. Accordingly, the 
    requirements of section 3(b) of E.O. 13084 do not apply to this rule.
    
    E. Regulatory Flexibility
    
        The Regulatory Flexibility Act (RFA) generally requires an agency 
    to conduct a regulatory flexibility analysis of any rule subject to 
    notice and comment rulemaking requirements unless the agency certifies 
    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 small governmental 
    jurisdictions. This final rule will not have a significant impact on a 
    substantial number of small entities because conditional approvals of 
    SIP submittals 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 this action will not have a significant economic impact on a 
    substantial number of small entities. Moreover, due to the nature of 
    the Federal-State relationship under the Clean Air Act, preparation of 
    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).
        If the conditional approval is converted to a limited approval/
    limited disapproval under section 110(k), based on the state's failure 
    to meet the commitment, it will not affect any existing state 
    requirements applicable to small entities. Federal disapproval of the 
    state submittal does not affect its state-enforceability. Moreover, 
    EPA's limited disapproval of the submittal does not impose a new 
    Federal requirement. Therefore, I certify that this disapproval action 
    will not have a significant economic impact on a substantial number of 
    small entities because it does not remove existing requirements nor 
    does it substitute a new federal requirement.
    
    F. 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 
    the 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 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.
    
    G. Submission to Congress and the Comptroller General
    
        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
    
    [[Page 12013]]
    
    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).
    
    H. 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 May 10, 1999. 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).) EPA encourages 
    interested parties to comment in response to the proposed rule rather 
    than petition for judicial review, unless the objection arises after 
    the comment period allowed for in the proposal.

        2. Section 52.369 is added to read as follows:
    
    
    Sec. 52.369  Identification of plan--Conditional approval
    
        (a) Elements of the I/M revision to the State Implementation Plan 
    submitted by the Connecticut Department of Environmental Protection on 
    June 24, 1998 which address the following sections of the I/M 
    regulation are conditionally approved: Network Type and Program 
    Evaluation--40 CFR 51.353, Waivers and Compliance Via Diagnostic 
    Inspection--40 CFR 51.360, Motorist Compliance Enforcement Program 
    Oversight--40 CFR 51.362, Quality Assurance--40 CFR 51.363, Enforcement 
    Against Contractors, Stations and Inspectors--40 CFR 51.364, Public 
    Information and Consumer Protection--40 CFR 51.368, Compliance with 
    Recall Notices--40 CFR 51.370, and On-road Testing--40 CFR 51.371. If 
    Connecticut fails to submit SIP revisions to meet these conditions by 
    July 1, 1999 at the latest, the conditional approval of these sections 
    of the Enhanced I/M SIP will automatically convert to a disapproval as 
    explained under Sec. 110(k) of the Clean Air Act.
        (b) EPA is also approving this I/M SIP revision under Sec. 110(k) 
    of the Clean Air Act for its strengthening effect on the plan. The I/M 
    SIP shall remain an enforceable SIP requirement even if Connecticut 
    fails to meet the conditions set forth in Sec. 369(a).

        4. Section 52.376 is amended by revising paragraphs (a) and (d) and 
    adding paragraphs (e) and (f) to read as follows:
    
    
    Sec. 52.376  Control Strategy: Carbon Monoxide.
    
        (a) Approval--On January 12, 1993, the Connecticut Department of 
    Environmental Protection submitted a revision to the carbon monoxide 
    State Implementation Plan for the 1990 base year emission inventory. 
    The inventory was submitted by the State of Connecticut to satisfy 
    Federal requirements under sections 172(c)(3) and 187(a)(1) of the 
    Clean Air Act as amended in 1990, as a revision to the carbon monoxide 
    State Implementation Plan for the Hartford/New Britain/Middletown 
    carbon monoxide nonattainment area, the New Haven/Meriden/Waterbury 
    carbon monoxide nonattainment area, and the Connecticut Portion of the 
    New York-N. New Jersey-Long Island carbon monoxide nonattainment area.
    * * * * *
        (d) Approval--On January 17, 1997, the Connecticut Department of 
    Environmental Protection submitted a request to redesignate the New 
    Haven/Meriden/Waterbury carbon monoxide nonattainment area to 
    attainment for carbon monoxide. As part of the redesignation request, 
    the State submitted a maintenance plan as required by 175A of the Clean 
    Air Act, as amended in 1990. Elements of the section 175A maintenance 
    plan include a base year emission inventory for carbon monoxide, a 
    demonstration of maintenance of the carbon monoxide NAAQS with 
    projected emission inventories to the year 2008 for carbon monoxide, a 
    plan to verify continued attainment, a contingency plan, and an 
    obligation to submit a subsequent maintenance plan revision in 8 years 
    as required by the Clean Air Act. If the area records a violation of 
    the carbon monoxide NAAQS (which must be confirmed by the State), 
    Connecticut will implement one or more appropriate contingency 
    measure(s) which are contained in the contingency plan. The menu of 
    contingency measure includes reformulated gasoline and the enhanced 
    motor vehicle inspection and maintenance program. The redesignation 
    request establishes a motor vehicle emissions budget of 229 tons per 
    day for carbon monoxide to be used in determining transportation 
    conformity for the New Haven/Meriden/Waterbury area. The redesignation 
    request and maintenance plan meet the redesignation requirements in 
    sections 107(d)(3)(E) and 175A of the Act as amended in 1990, 
    respectively.
        (e) Approval--In December, 1996, the Connecticut Department of 
    Environmental Protection submitted a revision to the carbon monoxide 
    State Implementation Plan for the 1993 periodic emission inventory. The 
    inventory was submitted by the State of Connecticut to satisfy Federal 
    requirements under section 187(a)(5) of the Clean Air Act as amended in 
    1990, as a revision to the carbon monoxide State Implementation Plan.
        (f) Approval--On May 29, 1998, the Connecticut Department of 
    Environmental Protection submitted a request to redesignate the 
    Connecticut portion of the New York-N. New Jersey-Long Island carbon 
    monoxide nonattainment area to attainment for carbon monoxide. As part 
    of the redesignation request, the State submitted a maintenance plan as 
    required by 175A of the Clean Air Act, as amended in 1990. Elements of 
    the section 175A maintenance plan include a periodic emission inventory 
    for carbon monoxide, a demonstration of maintenance of the carbon 
    monoxide NAAQS with projected emission inventories to the year 2010 for 
    carbon monoxide, a plan to verify continued attainment, a contingency 
    plan, and an obligation to submit a subsequent maintenance plan 
    revision in 8 years as required by the Clean Air Act. If the area 
    records an exceedance of the carbon monoxide NAAQS (which must be 
    confirmed by the State), Connecticut will implement one or more 
    appropriate contingency measure(s) which are contained in the 
    contingency plan. The menu of contingency measure includes 
    investigating local traffic conditions, the enhanced motor vehicle 
    inspection and maintenance program, and the low emissions vehicles 
    program (LEV). The redesignation request establishes a motor vehicle 
    emissions budget of 205 tons per day for carbon monoxide to be used in 
    determining transportation conformity in the Connecticut Portion of the 
    New York-N. New Jersey-Long Island Area. The redesignation request and 
    maintenance plan meet the redesignation requirements in sections 
    107(d)(3)(E) and 175A of the Act as amended in 1990, respectively.
