                        plan revision, to approve under this paragraph 
                        any fuel included in such plan or revision if 
                        the effect of such approval would be to

                        under this paragraph as of January 1, 2009 in 
                        all State implementation plans.

                        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

    ``(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.--

        this subparagraph, the term `motor fuel distribution system' 
        has the meaning given the term by the Administrator, by 
        regulation.
            ``(ii) Requirements.--A waiver under subparagraph (D) shall 
        be permitted only if--
                    ``(I) the waiver applies to the smallest geographic 
                area necessary to address the extreme and unusual fuel 
                or fuel additive supply circumstance;
                    ``(II) the waiver is effective for a period of 15 
                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 
                motor fuel distribution system; and
                    ``(V) the Administrator has given public notice 
                regarding consideration by the Administrator of, and, 
                if applicable, the granting of, a waiver to all parties 
                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
            ``(ii) subjects any State or person to an enforcement 
        action, penalties, or liability solely arising from actions 
        taken pursuant to the issuance of a waiver under subparagraph 
        (D).''.
Motor Fuel Supply and Distribution Improvement Act - Amends the Clean Air Act to: (1) update provisions limiting the number of gasoline or diesel fuels allowed in a state implementation plan; and (2) allow a limited, temporary waiver of a control or prohibition of a fuel or fuel additive in circumstances that prevent the distribution of an adequate supply of such fuel or fuel additive to consumers.
