A bill to amend the Clean Air Act to permit the Governor of a State to waive oxygen content requirement for reformulated gasoline, to encourage development of voluntary standards to prevent and control releases of methyl tertiary butyl ether from underground storage tanks, to establish a program to phase out the use of methyl tertiary butyl ether, and for other purposes.

Summary: Requires the Administrator to promulgate regulations to ensure that the benefits of toxic air pollutant reductions under the reformulated gasoline program are maintained in States for which the oxygenate requirement is waived. Directs the Administrator, in promulgating such regulations, to: (1) develop designations for regions based on the extent and location of the U.S. gasoline distribution and supply network; and (2) use such designations to establish annual average performance standards for each region based on the existing phase II reformulated gasoline complex model and the annual reductions in toxic air pollutant emissions achieved in the region under the reformulated gasoline program during 1998 and 1999. Applies such standards to the manufacture of such gasoline sold in States for which the oxygenate requirement is waived, to the extent they are more stringent than those under existing law.
(Sec. 2) Directs the Administrator to study and report to Congress on whether additional standards to prevent and control releases of methyl tertiary butyl ether (MTBE) from underground storage tanks are necessary.
(Sec. 3) Authorizes the Administrator to control or prohibit the introduction into commerce or sale of any oxygenated fuel additive if it causes or contributes to air or water pollution that may be anticipated to endanger public health or welfare.
(Sec. 4) Prohibits, for the fourth calendar year after this Act's enactment date and thereafter, the quantity of gasoline sold or introduced into commerce by a gasoline refiner, blender, or importer from containing on average more than one percent by volume MTBE and bars such individuals from selling or introducing into commerce any gasoline that contains more than an historical level by volume of MTBE as determined by the Administrator. Authorizes the Administrator to promulgate regulations to permit such individuals to sell and purchase authorizations to sell or introduce into commerce gasoline containing MTBE in excess of the one percent limitation. Requires the Administrator to ensure that the total quantity of gasoline sold or introduced into commerce during any calendar year by all such individuals contains on average not more than one percent MTBE.
Permits States to submit State implementation plan revisions to the Administrator that provide for the reduction or elimination of the use of MTBE in gasoline in the State if the State Governor demonstrates that: (1) the reduction or elimination would not cause any significant disruption in the availability, supply, or price of gasoline in the State; (2) the reduction or elimination is necessary to protect public health or the environment; and (3) any alternative additive used will not present an equivalent or greater problem than that posed by the use of MTBE.
Provides for technical assistance to States with facilities that produce MTBE to assist them in applying for, or modifying, permits as a result of provisions of this Act.
(Sec. 5) Requires, in order to ensure an adequate fuel supply for all States, any regulation or modification of fuel properties promulgated or approved by the Administrator under this Act to take into consideration the need for reasonable schedules for carrying out necessary refinery investment projects and making modifications to fuel distribution systems. Directs the Administrator, in implementing and enforcing such regulations and modifications, to provide the fuel industry with the flexibility inherent in existing fuel regulations.

        Administrator of the Environmental Protection Agency a State 
        implementation plan revision that provides for the reduction or 
        elimination of the use of methyl tertiary butyl ether in 
        gasoline sold or introduced into commerce in the State if the 
        Governor of the State demonstrates that--
                    (A) the reduction or elimination would not cause 
                any significant disruption in the availability, supply, 
                or price of gasoline in the State;
                    (B) the reduction or elimination is necessary to 
                protect the public health or environment; and
                    (C) any alternative additive used will not present 
                an equivalent or greater problem than any problem posed 
                by the use of methyl tertiary butyl ether.
            (2) Special rule.--Paragraph (1)--
                    (A) does not apply to a State described in section 
                211(c)(4)(B) of the Clean Air Act (42 U.S.C.

which are located 1 or more facilities that produce methyl tertiary 
butyl ether and that, as a result of any provision of or amendment made 
by this Act, apply for a new permit or permit modification under the 
Clean Air Act (42 U.S.C. 7401 et seq.), the Administrator of the 
Environmental Protection Agency shall provide to the State technical 
assistance and personnel to assist in the application for or 
modification of such permits.

SEC. 5. ASSURANCE OF ADEQUATE FUEL SUPPLY.

    (a) In General.--In order to ensure an adequate fuel supply for all 
States, any regulation or modification of fuel properties promulgated 
or approved by the Administrator of the Environmental Protection Agency 
under this Act or an amendment made by this Act shall take into 
consideration the need for reasonable schedules for carrying out 
necessary refinery investment projects and making appropriate 
modifications to fuel distribution systems.
    (b) Fuel Industry Flexibility.--In implementing and enforcing 
regulations and modifications described in subsection (a), the 
Administrator shall provide the fuel industry with the flexibility 
inherent in fuel regulations in effect on the day before the date of 
enactment of this Act.
