    OPINION AND ORDER OF THE BOARD (by T.E. Johnson):
    On August 20, 2001, the Illinois Environmental Protection Agency (Agency) filed a
    proposal to amend the Board’s regulations on inspecting and maintaining vehicles to control air
    emissions. Today, the Board accepts the Agency’s proposal for hearing.
    BACKGROUND
     
    Sections 182(b) and (c) of the federal Clean Air Act (CAA) (42 U.S.C §§ 7511a(b) and
    (c)) require states to implement vehicle “inspection and maintenance” (I/M) programs in areas
    that do not meet National Ambient Air Quality Standards (NAAQS) for ozone or carbon
    monoxide. Areas that do not meet NAAQS are referred to as “nonattainment” areas.
     
    The CAA requires “basic” I/M programs in “moderate” and “marginal” ozone
    nonattainment areas with existing I/M programs. It requires “enhanced” I/M programs in
    “serious,” “severe,” and “extreme” ozone nonattainment areas with a population of 200,000 or
    more. The CAA also requires states to submit, for the approval of the United States
    Environmental Protection Agency (USEPA), revisions to their State Implementation Plans
    (SIPs) that describe a satisfactory I/M program and assure that the I/M program will be
    implemented.
     
    In Illinois, two areas do not meet the NAAQS for ozone: (1) the Chicago metropolitan
    nonattainment area, which is a severe nonattainment area; and (2) the Metro-East St. Louis
    nonattainment area, which is a moderate nonattainment area. Under Illinois’ Vehicle Emissions
    Inspection Law of 1995 (Vehicle Emissions Law (625 ILCS 5/13B-1
    et seq.
    (2000)), the Agency
    has proposed, and the Board has adopted, as amendments to 35 Ill. Adm. Code 240, an enhanced
    I/M program for these two nonattainment areas. See Enhanced Vehicle Inspection and
    Maintenance (I/M) Regulations: Amendments to 35 Ill. Adm. Code 240 (July 8, 1998), R98-24;
    (December 1, 1994), R94-20; (December 1, 1994), R94-19. The Agency currently proposes to
    further amend the enhanced I/M program.

    DISCUSSION
    In this portion of the opinion, the Board describes the Agency’s proposal to amend 35 Ill.
    Adm. Code 240.191, 240.192, and 240.193; discusses the statutory framework governing this
    rulemaking; and describes how the Board will proceed with the Agency’s proposal.
    Agency Proposal
    Under Section 13B-20(a) of the Vehicle Emissions Law (625 ILCS 5/13B-20(a) (2000)),
    the Agency proposes amendments to 35 Ill. Adm. Code 240 with respect to the enhanced I/M
    program for the Chicago metropolitan and Metro-East St. Louis nonattainment areas. See
    Agency Statement of Reasons at 3-4. Through the proposed amendments, the Agency intends to
    provide a certain flexibility pursuant to recent USEPA rules for On Board Diagnostic (OBD) test
    standards. See Agency Statement of Reasons at 6. Specifically, the Agency states that its
    proposal would revise 35 Ill. Adm. Code 240 by:
    1. revising the text of Section 240.191 to refer to the OBD procedural rules
    contained in 35 Ill. Adm. Code 276;
    2. delaying mandatory “pass/fail” OBD testing to January 1, 2003, if the Agency
    chooses to apply to USEPA for this delay, and USEPA grants it;
    3. modifying the list of diagnostic trouble codes (DTC) that, if identified during an
    OBD test, will result in a vehicle’s failure;
    4. adding a malfunction indicator light (MIL) visual check, also known as a bulb
    check, to the OBD test; and
    5. revising the text of Section 240.193 to clarify that the inspection of any vehicle
    fault codes actually consists of the electronic retrieval of those stored fault codes.
    See Agency Statement of Reasons at 6-10.
    The Agency describes these proposed changes as “relatively minor adjustments to the
    Enhanced I/M program.” Agency Statement of Reasons at 5. The Agency states that it is
    proposing the amendments “to enable Illinois to meet federal and state mandated enhanced
    emissions testing requirements.”
    Id.
    at 3. The Agency also states that its proposal is “designed
    to promote the acceptance of and adherence to the enhanced I/M program, by incorporating
    necessary ‘flexibility’ provisions for OBD testing as authorized by recent USEPA rulemaking
    and guidance.”
    Id.
    at 5.
    Statutory Framework
    The Agency proposes to amend 35 Ill. Adm. Code 240 pursuant to Section 13B-20(a) of
    the Vehicle Emissions Law (625 ILCS 5/13B-20(a) (2000)). Section 13B-20(a) provides in part:
    The Agency shall propose standards necessary to achieve reductions in the
    emission of hydrocarbons, carbon monoxide, and oxides of nitrogen from motor
    vehicles subject to inspection under this Chapter. Within 120 days after the

     
    3
    Agency proposes these standards, the Board shall adopt rules establishing
    standards for the emission of hydrocarbons, carbon monoxide, and oxides of
    nitrogen from motor vehicles subject to inspection under this Chapter. These
    rules may be amended from time to time pursuant to Agency proposals.
    * * *
    [S]ubsection (b) of Section 27 of the Environmental Protection Act and the
    rulemaking provisions of the Illinois Administrative Procedure Act shall not
    apply to rules adopted by the Board under this subsection. 625 ILCS 5/13B-20(a)
    (2000).
    Proceedings Before the Board
    The Board accepts the Agency’s proposal for hearing. Because Section 13B-20(a) of the
    Vehicle Emissions Law requires the Board to adopt rules within 120 days after it receives the
    Agency’s proposal, the Board will, without commenting on the merits of the Agency’s proposal,
    proceed by publishing this proposal in the
    Illinois Register
    as a proposal for public comment.
    The hearing officer assigned to this rulemaking will establish a deadline for filing public
    comments.
    Pursuant to Section 28 of the Environmental Protection Act (Act) (415 ILCS 5/28
    (2000)), the Board will hold at least two public hearings during this rulemaking. The Board will
    hold one hearing in Chicago and one hearing in the Metro-East St. Louis area. The hearing
    officer will establish specific locations and times for the hearings. After considering the issues
    raised at the public hearings and in public comments, the Board will issue a final opinion and
    order and publish the adopted rules in the
    Illinois Register
    .
    As set forth above, Section 13B-20(a) of the Vehicle Emissions Law states that Section
    27(b) of the Act (415 ILCS 5/27(b) (2000)) and the rulemaking provisions of the Administrative
    Procedure Act (5 ILCS 100/1-1
    et seq.
    (2000)) “shall not apply to rules adopted by the Board
    under this subsection.” 625 ILCS 5/13B-20(a) (2000). Accordingly, the Board will not request
    that the Department of Commerce and Community Affairs conduct an economic impact study of
    the proposed amendments pursuant to Section 27(b) of the Act, nor will the Board submit the
    proposed amendments for first or second notice pursuant to Section 5-40 of the Administrative
    Procedure Act (5 ILCS 100/5-40 (2000)). The Board will, however, hold public hearings and
    solicit public comment as described above.
    The Board directs the hearing officer to schedule public hearings pursuant to Section 28
    of the Act. Further, as noted above, the proposal will be published as a proposal for public
    comment in the
    Illinois Register
    . The Board also notes that hearing transcripts and the Board’s
    opinions and orders in this rulemaking, including this opinion and order, will be available on the
    Board’s Web site (www.ipcb.state.il.us).
    ORDER

     
    4
    The Board directs the Clerk to file the following proposed amendments to 35 Ill. Adm.
    Code 240 with the Secretary of State to publish in the
    Illinois Register
    as a proposal for public
    comment. Proposed additions are underlined; proposed deletions are stricken.

    in 35 Ill. Adm. Code 276.209. Vehicles that receive a result of fail do not thereby fail their
    emissions test until January 1, 2002. However, this date shall be extended to January 1, 2003, if
    the Agency petitions the USEPA for such an extension, and the request for an extension is
