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. 1. Definitions In this Act: (1) Administrator The term Administrator (2) Mid-level ethanol blend The term mid-level ethanol blend 2. Evaluation (a) In general The Administrator, acting through the Assistant Administrator of the Office of Research and Development at the Environmental Protection Agency, shall— (1) not later than 45 days after the date of enactment of this Act, enter into an agreement with the National Academy of Sciences to provide, within 18 months after the date of enactment of this Act, a comprehensive assessment of the scientific and technical research on the implications of the use of mid-level ethanol blends, comparing mid-level ethanol blends to gasoline blends containing 10 percent or zero percent ethanol; and (2) not later than 30 days after receiving the results of the assessment under paragraph (1), submit a report to the Committee on Science, Space, and Technology of the House of Representatives and the Committee on Environment and Public Works of the Senate on the findings of the assessment, together with the agreement or disagreement of the Administrator with each of its findings. (b) 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) (c) Contents The assessment performed under subsection (a)(1) shall include the following: (1) An evaluation of the short-term and long-term environmental, safety, durability, and performance effects of the introduction of mid-level ethanol blends on onroad, nonroad, and marine engines, onroad and nonroad vehicles, and related equipment. Such evaluation shall consider the impacts of qualifying mid-level ethanol blends or blends with higher ethanol concentrations as a certification fuel, and shall consider the effect mid-level ethanol blends have on carbon emissions, taking into account carbon emissions from their life-cycle production, as compared to gasoline blends containing 10 percent or zero percent ethanol. Such evaluation shall include a review of all available scientific evidence, including all relevant government and industry data and testing, including that relied upon by the Administrator and published at 75 Fed. Reg. 68094 et seq. (November 4, 2010), 76 Fed. Reg. 4662 et seq. (January 26, 2011), and 76 Fed. Reg. 44406 et seq. (July 25, 2011), and identify gaps in understanding and research needs related to— (A) tailpipe emissions; (B) evaporative emissions; (C) engine and fuel system durability; (D) onboard diagnostics; (E) emissions inventory and other modeling effects; (F) materials compatibility; (G) operability and drivability; (H) fuel efficiency; (I) fuel economy; (J) consumer education and satisfaction; (K) cost-effectiveness for the consumer; (L) catalyst durability; and (M) 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; (ii) examining misfueling mitigation strategies for blender pumps, including volumetric purchase requirements and labeling requirements; (iii) assessing the adequacy of misfueling mitigation plans approved by the Environmental Protection Agency; and (iv) examining the technical standards and recommendations of the National Institute of Standards and Technology, the American National Standards Institute, and the International Organization for Standardization regarding fuel pump labeling. 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.

Summary: (Sec. 2) Requires the Assistant Administrator of the Office of Research and Development at the Environmental Protection Agency (EPA) to: enter into an agreement with the National Academy of Sciences to make a comprehensive assessment of research on the implications of using mid-level ethanol blends, comparing mid-level ethanol blends to gasoline blends containing 10% and 0% ethanol; and report on assessment findings and whether the EPA Administrator agrees or disagrees with each of them. Defines a mid-level ethanol blend as an ethanol-gasoline blend containing greater than 10% and up to and including 20% ethanol by volume that is intended to be used in any conventional gasoline-powered onroad, nonroad, or marine engine, or onroad or nonroad vehicle. Nullifies waivers granted under the Clean Air Act before the enactment of this Act that allow the introduction into commerce of mid-level ethanol blends for use in motor vehicles, and prohibits the Administrator from granting any new waivers until after the report is submitted. Requires the assessment to include: (1) an evaluation of 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) an identification of 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. Requires the evaluation to review all available scientific evidence and identify gaps in understanding and research needs related to tailpipe emissions, evaporative emissions, engine and fuel system durability, onboard diagnostics, emissions inventory and other modeling effects, materials compatibility, operability and drivability, fuel efficiency, fuel economy, consumer education and satisfaction, cost-effectiveness for the consumer, catalyst durability, and durability of storage tanks, piping, and dispensers for retail. (Sec. 3) Directs the Administrator to use certain funds made available to the EPA for science and technology, including research and development activities, to carry out this Act.
