            ``(A) the upwind area reduce emissions of ozone or its 
        precursors by an amount determined by the State to be necessary 
        to mitigate impacts commensurate with the level of contribution 
        caused by the upwind area to air pollution concentrations in 
        the downwind area; or
            ``(B) the upwind area make payments to the State or to an 
        air quality district designated by the State to compensate the 
        downwind area in such amounts as such State finds necessary to 
        pay for the costs of emission reduction measures required to be 
        undertaken in the downwind area to fully mitigate the impacts 
of pollutants transported from the upwind area.''.
    (b) Requirements for Moderate Ozone Nonattainment Areas.--Paragraph 
(4) of section 182(b) of the Clean Air Act is amended by adding the 
following at the end thereof:

        reductions in emissions of ozone or its precursors by an amount 
        determined by the Administrator to be necessary to mitigate 
        impacts commensurate with the level of contribution caused by 
        sources in the upwind State to ozone concentrations in the 
        downwind area.
            ``(2) Provisions under which the upwind State will make 
        payments to the State or States in which all or part of the 
        downwind area is located or to an air quality district 
        designated by the Administrator to compensate such State or 
        States in such amounts as the Administrator finds necessary to 
        pay for the costs of emission reduction measures required to be 
        undertaken in the downwind area to fully mitigate the impacts 
of pollutants transported from the upwind State.''.
    (b) Requirements for Moderate Ozone Nonattainment Areas.--Paragraph 
(4) of section 182(b) of the Clean Air Act is amended by adding the 
following at the end thereof:
            ``(C) For each moderate area which the Administrator 
        determines to cause or significantly contribute to a violation 
        of the national ambient air quality standards for ozone in a 
        downwind area (as identified by the Administrator under section 
        126(d)), the State shall submit, within 1 year after such 
        determination, a revision to the applicable implementation plan 
        that includes all provisions necessary to provide for an 
        enhanced vehicle inspection and maintenance program as 
        described in paragraph (3) of subsection (c) of this section 
        and the regulations of the Administrator adopted pursuant to 
        such paragraph (3).''.

SEC. 4. MAINTENANCE PLANS.

    (a) Requirements for Maintenance Plans.--(1) Subsection (a) of 
section 175A of the Clean Air Act is amended by adding the following at 
the end thereof: ``Such plan shall also be amended within 1 year after 
the later of--
            ``(1) the date of enactment of the Transported Air 
        Pollution Mitigation Act of 1997, or
            ``(2) the date on which the request under section 107(d) is 
        submitted
to include measures to provide for an enhanced vehicle inspection and 
maintenance program as described in paragraph (3) and (4) of section 
182(c) and the regulations of the Administrator adopted pursuant to 
such paragraphs if the State determines that the area requesting 
redesignation is causing or significantly contributing to a violation 
of the national ambient air quality standards for ozone in a downwind 
area (as identified by the State under section 110(a)(4)) or if the 
Administrator determines that the area requesting redesignation is 
causing or significantly contributing to a violation of the national 
ambient air quality standards for ozone in a downwind State (as 
identified by the Administrator under section 126(d)).''.
    (b) Transport Mitigation.--Section 175A of the Clean Air Act is 
amended by adding the following at the end thereof:
    ``(e) Transport Mitigation.--Each plan adopted under this section 
shall be amended within 1 year after the enactment of this subsection 
to require that any upwind area (as identified by the State under 
section 110(a)(4)) and any upwind State (as identified by the 
Administrator under section 126(d)) that is designated as an attainment 
area that causes or significantly contributes to a violation of the 
national ambient air quality standard for ozone in any downwind area 
(as identified under section 110(a)(4) or section 126(d)) shall be 
required by the applicable implementation plans under section 110 and 
this part to implement all measures with respect to the air pollutant 
concerned which were contained in the State implementation plan for 
such upwind area before its redesignation as an attainment area. Such 
measures shall include all existing control measures, as well as any 
control measures not yet implemented that are necessary to fully 
mitigate the transport of ozone and its precursors to such downwind 
areas. There shall be no relaxation or rescission of any control 
measure or rule in the upwind area or unwind State as long as sources 
in such upwind area or State cause or contribute to a violation of the 
national ambient air quality standard for ozone in any such downwind 
area.''.

Summary: Transported Air Pollution Mitigation Act of 1997 - Amends Clean Air Act provisions regarding State implementation plans for national primary and secondary ambient air quality standards to require a State, for each upwind area which causes or significantly contributes to a violation of the ambient air quality standard for ozone in a downwind area, to submit a plan revision that requires the upwind area to either: (1) reduce emissions of ozone or its precursors by an amount necessary to mitigate impacts to pollution concentrations in the downwind area commensurate with the level of contribution caused. Or (2) make payments to the State or the air quality district as compensation to the downwind area for the costs of emission reduction measures to fully mitigate the impacts of transported pollutants. Directs States which cause or significantly contribute to violations of such standards in another State to revise plan provisions for interstate pollution abatement to meet the requirements described above. Requires a State, for each Moderate ozone nonattainment area determined to cause or significantly contribute to a violation of the national ambient air quality standard for ozone in a downwind area or State, to submit a plan revision including all provisions necessary for an enhanced vehicle inspection and maintenance program described in provisions concerning Serious areas and Environmental Protection Agency regulations. Requires amendment by a State of its plan for maintenance to include measures for such an inspection program if the area concerned is causing or significantly contributing to a violation of such standards for ozone in a downwind area or State. Provides for amendments to maintenance plans in upwind areas and States that cause or significantly contribute to violations of such standards in downwind areas or States to require implementation of all measures contained in the State implementation plan for upwind areas before redesignation as attainment areas. Requires implementation of all control measures necessary to fully mitigate the transport of ozone and its precursors to downwind areas. Prohibits any relaxation or rescission of such measures as long as an upwind area or State contributes to such violations in a downwind area.
