                 TITLE 42--THE PUBLIC HEALTH AND WELFARE
 
            CHAPTER 85--AIR POLLUTION PREVENTION AND CONTROL
 
          SUBCHAPTER II--EMISSION STANDARDS FOR MOVING SOURCES
 
                       Part C--Clean Fuel Vehicles
 
Sec. 7581. Definitions

    For purposes of this part--

                     (1) Terms defined in part A

        The definitions applicable to part A under section 7550 of this 
    title shall also apply for purposes of this part.

                     (2) Clean alternative fuel

        The term ``clean alternative fuel'' means any fuel (including 
    methanol, ethanol, or other alcohols (including any mixture thereof 
    containing 85 percent or more by volume of such alcohol with 
    gasoline or other fuels), reformulated gasoline, diesel, natural 
    gas, liquefied petroleum gas, and hydrogen) or power source 
    (including electricity) used in a clean-fuel vehicle that complies 
    with the standards and requirements applicable to such vehicle under 
    this subchapter when using such fuel or power source. In the case of 
    any flexible fuel vehicle or dual fuel vehicle, the term ``clean 
    alternative fuel'' means only a fuel with respect to which such 
    vehicle was certified as a clean-fuel vehicle meeting the standards 
    applicable to clean-fuel vehicles under section 7583(d)(2) of this 
    title when operating on clean alternative fuel (or any CARB 
    standards which replaces such standards pursuant to section 7583(e) 
    of this title).

                              (3) NMOG

        The term nonmethane organic gas (``NMOG'') means the sum of 
    nonoxygenated and oxygenated hydrocarbons contained in a gas sample, 
    including, at a minimum, all oxygenated organic gases containing 5 
    or fewer carbon atoms (i.e., aldehydes, ketones, alcohols, ethers, 
    etc.), and all known alkanes, alkenes, alkynes, and aromatics 
    containing 12 or fewer carbon atoms. To demonstrate compliance with 
    a NMOG standard, NMOG emissions shall be measured in accordance with 
    the ``California Non-Methane Organic Gas Test Procedures''. In the 
    case of vehicles using fuels other than base gasoline, the level of 
    NMOG emissions shall be adjusted based on the reactivity of the 
    emissions relative to vehicles using base gasoline.

                          (4) Base gasoline

        The term ``base gasoline'' means gasoline which meets the 
    following specifications:

    Specifications of Base Gasoline Used
      as Basis for Reactivity 
    Readjustment:
              API gravity.......................                   57.8

              Saturates.........................                   60.9 

    The Administrator shall modify the definitions of NMOG, base 
    gasoline, and the methods for making reactivity adjustments, to 
    conform to the definitions and method used in California under the 
    Low-Emission Vehicle and Clean Fuel Regulations of the California 
    Air Resources Board, so long as the California definitions are, in 
    the aggregate, at least as protective of public health and welfare 
    as the definitions in this section.

                          (5) Covered fleet

        The term ``covered fleet'' means 10 or more motor vehicles which 
    are owned or operated by a single person. In determining the number 
    of vehicles owned or operated by a single person for purposes of 
    this paragraph, all motor vehicles owned or operated, leased or 
    otherwise controlled by such person, by any person who controls such 
    person, by any person controlled by such person, and by any person 
    under common control with such person shall be treated as owned by 
    such person. The term ``covered fleet'' shall not include motor 
    vehicles held for lease or rental to the general public, motor 
    vehicles held for sale by motor vehicle dealers (including 
    demonstration vehicles), motor vehicles used for motor vehicle 
    manufacturer product evaluations or tests, law enforcement and other 
    emergency vehicles, or nonroad vehicles (including farm and 
    construction vehicles).

                      (6) Covered fleet vehicle

        The term ``covered fleet vehicle'' means only a motor vehicle 
    which is--
            (i) in a vehicle class for which standards are applicable 
        under this part; and
            (ii) in a covered fleet which is centrally fueled (or 
        capable of being centrally fueled).

    No vehicle which under normal operations is garaged at a personal 
    residence at night shall be considered to be a vehicle which is 
    capable of being centrally fueled within the meaning of this 
    paragraph.

                       (7) Clean-fuel vehicle

        The term ``clean-fuel vehicle'' means a vehicle in a class or 
    category of vehicles which has been certified to meet for any model 
    year the clean-fuel vehicle standards applicable under this part for 
    that model year to clean-fuel vehicles in that class or category.
