                    (N) durability of storage tanks, piping, and 
                dispensers for retail.
            (2) An identification of areas of research, development, 
        and testing necessary to--
                    (A) ensure that existing motor fuel infrastructure 
                is not adversely impacted by mid-level ethanol blends, 
                including an examination of potential impacts of mid-
                level ethanol blends on metal, plastic, rubber, or any 
                other materials used in pipes or storage tanks; and
                    (B) reduce the risk of misfueling by users at 
                various points in the distribution and supply chain, 
                including at bulk storage, retail storage, and 
                distribution configurations by--
                            (i) assessing the best methods and 
                        practices to prevent misfueling;

                        regarding fuel pump labeling.
    (c) Waivers.--Prior to the submission of the report under 
subsection (a)(2), any waiver granted under section 211(f)(4) of the 
Clean Air Act (42 U.S.C. 7545(f)(4)) before the date of enactment of 
this Act that allows the introduction into commerce of mid-level 
ethanol blends for use in motor vehicles shall have no force or effect. 
The Administrator shall grant no new waivers under such section 
211(f)(4) until after the submission of the report described under 
subsection (a)(2).

SEC. 3. AUTHORIZATION OF APPROPRIATIONS.

    In order to carry out this Act, the Administrator shall utilize up 
to $900,000 from the funds made available for science and technology, 
including research and development activities, at the Environmental 
Protection Agency.
This bill requires the Office of Research and Development at the Environmental Protection Agency to enter into an agreement with the National Academy of Sciences to provide a comprehensive assessment of research on the implications of the use of mid-level ethanol blends, which compares mid-level ethanol blends to gasoline blends containing 10% or 0% ethanol. A mid-level ethanol blend is an ethanol-gasoline blend containing 10%- 20% of ethanol that is intended to be used in any conventional gasoline-powered motor vehicle or nonroad vehicle or engine.  The assessment must: (1) evaluate the environmental, safety, durability, and performance effects of the introduction of mid-level blends on onroad, nonroad, and marine engines, onroad and nonroad vehicles, and related equipment; and (2) identify areas of research, development, and testing necessary to ensure that existing motor fuel infrastructure is not adversely impacted by mid-level ethanol blends and to reduce the risk of misfueling by users at various points in the distribution and supply chain. The office must report on the assessment's findings. Any waivers granted under the Clean Air Act to allow the sale of mid-level ethanol blends for use in motor vehicles are nullified. The office is also prohibited from granting new waivers until after the report is submitted. 
To provide for a comprehensive assessment of the scientific and technical research on the implications of the use of mid-level ethanol blends, and for other purposes.
