To amend the Clean Air Act to prohibit the use of methyl tertiary butyl ether as a gasoline additive and to repeal the oxygenate requirement for reformulated gasoline, to provide funding for the clean up of underground storage tanks, and for other purposes.

Summary: Amends the Clean Air Act to prohibit the use of methyl tertiary butyl ether (MBTE) as a motor vehicle fuel additive.

Repeals the oxygen content requirement for reformulated gasoline.

Requires the Administrator of the Environmental Protection Agency to promulate regulations which continue required toxic air pollutant emissions reductions from reformulated gasoline.

Authorizes appropriations from the Leaking Underground Storage Tank Trust Fund.

SECTION 1. MTBE PROHIBITION.

    (a) MTBE Prohibition.--Section 211(c) of the Clean Air Act (42 
U.S.C. 7545(c)) is amended by adding at the end the following:
            ``(5) Prohibition on use of mtbe.--
                    ``(A) In general.--Subject to subparagraph (C), not 
                later than 6 months after the date of enactment of this 
                paragraph, the use of methyl tertiary butyl ether in 
                motor vehicle fuel in any State is prohibited.
                    ``(B) Regulations.--The Administrator shall 
                promulgate regulations to carry out the prohibition set 
                forth in subparagraph (A).

                subparagraph (A), the Administrator may allow trace 
                quantities of methyl tertiary butyl ether, not to 
                exceed 0.5 percent by volume, to be present in motor 
                vehicle fuel in cases that the Administrator determines 
                to be appropriate.''.
    (b) No Effect on Law Concerning State Authority.--The amendments 
made by subsection (a) have no effect on the law in effect on the day 
before the date of enactment of this Act regarding the authority of 
States to limit the use of methyl tertiary butyl ether in motor vehicle 
fuel.

applicable to a specific refinery or importer made under such prior 
regulations and the Administrator may apply such adjustments to the 
standards applicable to such refinery or importer under clause (iii)(I) 
of section 211(k)(1)(B) of the Clean Air Act, except that--
            (1) the Administrator shall revise such adjustments to be 
        based only on calendar years 1999-2000; and

        from reformulated gasoline significantly below the national 
        annual average emissions of toxic air pollutants from all 
        reformulated gasoline, the Administrator may revise such 
        adjustments to take account of the scope of any lawful and 
        enforceable Federal or State prohibition on methyl tertiary 
        butyl ether imposed after the effective date of the enactment 
        of this paragraph, except that any such adjustment shall 
        require such refiner or importer, to the greatest extent 
        practicable, to maintain the reduction achieved during calendar 
        year 1999-2000 in the average annual aggregate emissions of 
        toxic air pollutants from reformulated gasoline produced or 
        distributed by the refinery or importer. Any such adjustment

        reductions of emissions of toxic air pollutants for 
        reformulated gasoline supplied to PADD I during calendar years 
        1999-2000.
