    In lieu of intermediate useful life standards (50,000 miles)
    or to gain additional nitrogen oxides credit, manufactur-
    ers may optionally certify to the Tier 2 exhaust emission
    standards with a useful life of 150,000 miles.
b   Bins 9-11 expire in 2006 for light-duty vehicles and light
    light-duty trucks and 2008 for heavy light-duty trucks and
    medium-duty passenger vehicles.
