LOS ANGELES -- California officials are suing the U.S. Environmental Protection Agency in hopes of reversing a decision requiring vehicles in the state to use the gasoline additive ethanol.
The lawsuit, filed Friday afternoon in the 9th U.S. Circuit Court of Appeals in San Francisco, calls on the agency to waive rules requiring ethanol to be added to most of the state's gasoline. Ethanol adds oxygen to gasoline to make it burn cleaner.
Gov. Gray Davis has ordered that MTBE -- the only oxygenate available besides ethanol -- be phased out by 2003 because it pollutes ground water. State officials argue that California can meet federal air-quality goals with non-oxygenated, reformulated gasoline.
