SEC. 2. IMPROVING MOTOR FUEL SUPPLY AND DISTRIBUTION.

    (a) Limiting Number of Boutique Fuels.--Section 211(c)(4)(C) of the 
Clean Air Act (42 U.S.C. 7545(c)(4)(C)) is amended by striking the 
second clause (v) (as added by section 1541(b) of Public Law 109-58) 
and inserting the following:
                            ``(vi)(I) The Administrator shall have no 
                        authority, when considering a State 
                        implementation plan or a State implementation 
                        plan revision, to approve under this paragraph 
                        any fuel included in such plan or revision if 
                        the effect of such approval would be to 
                        increase the total number of fuels approved 
                        under this paragraph as of January 1, 2009 in 
                        all State implementation plans.
                            ``(II) The Administrator, in consultation 
                        with the Secretary of Energy, shall determine

                        paragraph as of January 1, 2009, in all State 
                        implementation plans and shall publish a list 
                        of such fuels, including the States and 
                        Petroleum Administration for Defense District

                        fuel from the list published under subclause

                        implementation plan or if a fuel in a State 
                        implementation plan is identical to a Federal 
                        fuel formulation implemented by the 
                        Administrator, but the Administrator shall not 
                        reduce the total number of fuels authorized 
                        under the list published under subclause (II).

    (b) Temporary Waivers During Supply Emergencies.--Section 211(c)(4) 
of the Clean Air Act (42 U.S.C. 7545(c)(4)) is amended by adding at the 
end the following:
    ``(D) Temporary Waivers During Supply Emergencies.--The 
Administrator may temporarily waive a control or prohibition with 
respect to the use of a fuel or fuel additive required or regulated by 
the Administrator under subsection (c), (h), (i), (k), or (m), or 
prescribed in an applicable implementation plan under section 110 that 
is approved by the Administrator under subparagraph (c)(4)(C)(i), if, 
after consultation with and concurrence by the Secretary of Energy, the 
Administrator determines that--
            ``(i) an extreme and unusual fuel or fuel additive supply 
        circumstance exists in a State or region that prevents the 
        distribution of an adequate supply of the fuel or fuel additive 
        to consumers;
            ``(ii) the extreme and unusual fuel or fuel additive supply 
        circumstance is the result of a natural disaster, an act of 
        God, a pipeline or refinery equipment failure, or another event 
        that could not reasonably have been foreseen or prevented and 
        not a lack of prudent planning on the part of the suppliers of 
        the fuel or fuel additive to the State or region; and
            ``(iii) it is in the public interest to grant the waiver.
    ``(E) Requirements for Waiver.--

        be permitted only if--

                calendar days or, if the Administrator determines that 
                a shorter or longer waiver period is adequate, for the 
                shortest practicable time period necessary to permit 
                the correction of the extreme and unusual fuel or fuel 
                additive supply circumstances and to mitigate impact on 
                air quality;
                    ``(III) the waiver permits a transitional period, 
                the duration of which shall be determined by the 
                Administrator, after the termination of the temporary 
                waiver to permit wholesalers and retailers to blend 
                down wholesale and retail inventory;
                    ``(IV) the waiver applies to all persons in the

                in the motor fuel distribution system, State and local 
                regulators, public interest groups, and consumers in 
                the State or region to be covered by the waiver.
    ``(F) Affect on Waiver Authority.--Nothing in subparagraph (D)--
            ``(i) limits or otherwise affects the application of any 
        other waiver authority of the Administrator under this section 
        or a regulation promulgated pursuant to this section; or

        action, penalties, or liability solely arising from actions 
        taken pursuant to the issuance of a waiver under subparagraph
