Title I: Provisions for Attainment and Maintenance of National Ambient Air Quality Standards - Amends the Clean Air Act to require State Governors to designate areas within a State as nonattainment, attainment, or unclassifiable, with regard to air quality standards, and to submit such designations to the Administrator of the Environmental Protection Agency (EPA) no later than one year after the promulgation of a new or revised air quality standard. Authorizes the Administrator to modify such designations, as necessary. Designates areas currently required to be listed under the Clean Air Act as nonattainment, attainment, or unclassifiable areas, as specified. Provides for the redesignation of areas, as appropriate. Prohibits the redesignation of any area from nonattainment to unclassifiable.

Revises the boundaries of Serious, Severe, or Extreme ozone or carbon monoxide nonattainment areas located in metropolitan statistical areas (MSAs) or consolidated metropolitan statistical areas (CMSAs) to include the entire MSA or CMSA unless the State Governor notifies the Administrator that additional time is necessary to evaluate such revision. Excludes areas within the MSA or CMSA that do not contribute to violation of the air quality standard, subject to the Administrator's approval.

Designates: (1) areas identified (in 52 Federal Register 29383) as Group I areas as particulate matter 10 (PM-10) nonattainment areas; (2) areas containing sites for which air quality monitoring data show a violation of national air quality standards for PM-10 before 1989 as PM-10 nonattainment areas; and (3) areas not meeting either description as PM-10 unclassifiable areas.

Authorizes the Administrator to require States to designate areas with respect to the national air quality standard for lead.

Revises provisions concerning State implementation plan requirements. Sets forth provisions for plan approval and revision.

Requires plans to provide for attainment of national air quality standards in nonattainment areas within three years of this Act's enactment or within five years of a finding of substantial inadequacy.

Retains a moratorium on construction or modification of major stationary sources in certain areas until such areas meet applicable requirements concerning permit programs or attainment standards for sulfur dioxide.

Repeals provisions concerning: (1) extensions of time for attainment dates; (2) requirements concerning parking surcharges and transportation regulations; and (3) suspensions of certain plan requirements.

Requires the Administrator to publish a triennial (currently, annual) document which sets forth applicable requirements of the implementation plan for each State.

Requires Federal transportation programs to implement transportation provisions of implementation plans. Prohibits Federal agencies from funding or approving any transportation program unless it conforms to an implementation plan in effect under this Act.

Sets the date of attainment of national air quality standards for a nonattainment area at five years from the date such area was designated. Authorizes the Administrator to extend such attainment date, provided that such extension does not exceed ten years. Permits up to two one-year extensions to be granted to a single area upon application by a State.

Requires States to submit nonattainment plans within three years of the designation of an area. Makes technical amendments to provisions concerning nonattainment plan requirements.

Requires the Administrator, after relaxing an air quality standard, to promulgate requirements applicable to areas that have not attained the standard as of the date of such relaxation.

Authorizes the issuance of a permit to construct or operate a new source if demonstrated that the benefits of such source significantly outweigh environmental and social costs.

Prohibits the use of existing growth allowances in areas which are notified that implementation plans containing such allowances are substantially inadequate.

Allows new or modified major stationary sources to comply with any offset requirement for increased air pollutant emissions with reductions of the pollutant from such sources or from other sources in the same nonattainment area. Permits the sources to obtain reductions in another nonattainment area if the other area has an equal or higher nonattainment classification and emissions from the other area contribute to violations of air quality standards in the area in which the sources are located. Requires such reductions to be in effect by the time such sources commence operation and to assure that the total tonnage of increased emissions is offset by an equal or greater reduction in the actual emissions from the same or other area sources.
