    July 21, 2005) which provides guidance on deternining
    the equivalency of vehicle and engine emission standards
    in the CFR Part 86 standards and Part 88 standards for
    Clean-Fuel Vehicles.
b   Applies to diesel vehicles only.
c   Applies to Inherently Low Emission Vehicles.
d   Does not apply to diesel vehicles.
