SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Clean Airport Bus Act of 2003''.

SEC. 2. ESTABLISHMENT OF PILOT PROGRAM.

    (a) Establishment.--The Secretary of Transportation shall establish 
a pilot program for awarding grants on a competitive basis to eligible 
entities for facilitating the use of natural gas buses at public 
airports through airport bus replacement and fleet expansion programs 
under this section.
    (b) Requirements.--Not later than 3 months after the date of 
enactment of this Act, the Secretary shall establish and publish in the 
Federal Register grant requirements on eligibility for assistance, and 
on management, transfer, and ultimate disposition of buses, including 
certification requirements to ensure compliance with this Act.
    (c) Solicitation.--Not later than 6 months after the date of 
enactment of this Act, the Secretary shall solicit proposals for grants 
under this section.
    (d) Eligible Recipients.--A grant shall be awarded under this 
section only to a public agency responsible for bus service at a public 
airport.
    (e) Types of Grants.--
            (1) In general.--Grants under this section may be for the 
        purposes described in paragraph (2), paragraph (3), or both.
            (2) Replacement bus grants.--A grant under this section may 
        be used for the acquisition of replacement buses pursuant to 
        subsection (f).
            (3) Fleet expansion bus grants.--A grant under this section 
        may be used for the acquisition of not more than 10 buses to 
        expand a fleet of airport buses at any single airport.
    (f) Replacement Bus Grants.--
            (1) Replacement.--For each bus acquired under a replacement 
        bus grant, 1 older model year bus shall be retired from active 
        service and crushed as provided in paragraph (2).
            (2) Bus acquisition.--Buses acquired under a replacement 
        bus grant shall be acquired in the following order:
                    (A) First, new buses will replace buses 
                manufactured before model year 1977, and the older 
                buses replaced shall be crushed.
                    (B) If all buses manufactured before model year 
                1977 owned or operated by the grant recipient have been 
                replaced, additional new buses will replace diesel-
                powered buses manufactured before model year 1991, 
                which shall either--
                            (i) be crushed; or
                            (ii) be exchanged by the grant recipient 
                        for buses manufactured before model year 1977 
                        from another bus fleet, with that bus then 
                        being crushed.
                Exchanges made under subparagraph (B)(ii) shall be made 
                without profit or other economic benefit to the grant 
                recipient.
