Revises the formula the Administrator of the Environmental Protection Agency (EPA) uses to calculate fuel economy for dual-fueled automobiles operating with gaseous fuel, such as natural gas or hydrogen. Requires the EPA to apply utility factors based on the driving range for such automobiles. Allows the EPA to use a different methodology to calculate the fuel economy for dual-fueled, electric automobiles.
Makes permanent the state's authority to exempt alternative fuel vehicles from high occupancy vehicle (HOV) lane restrictions. Makes eligible only those alternative fuel vehicles operating solely on alternative fuel, including electric vehicles.
Requires the Secretary of Energy (DOE) to report on incentives and financing tools to develop public compressed natural gas fueling stations.
