On March 25, 1999, Davis issued an executive order calling for the removal of MTBE (a toxic gasoline additive) from gasoline sold in the state. In 2001, in order for gas prices to remain reasonable in California while removing MTBE, Davis asked President George W. Bush to order the EPA to grant California a waiver on the federal minimum oxygen requirement. Without a waiver, California would have to import a much larger amount of ethanol per year and gas prices were projected to increase drastically. Bush did not grant the waiver and in 2002, Davis issued an executive order reversing his earlier executive order.
