    (c) Qualified alternative fuel vehicle refueling property
      For purposes of this section, the term "qualified alternative
    fuel vehicle refueling property" has the same meaning as the term

      (a) for any taxable year (determined without regard to this
      subsection) that is attributable to property of a character
      subject to an allowance for depreciation shall be treated as a
      credit listed in section 38(b) for such taxable year (and not
      allowed under subsection (a)).
      (2) Personal credit
        The credit allowed under subsection (a) (after the application

      sold such property to the person or entity using such property
      shall be treated as the taxpayer that placed such property in
      service, but only if such person clearly discloses to such person
      or entity in a document the amount of any credit allowable under
      subsection (a) with respect to such property (determined without
