States no longer will have to add corn-based ethanol or MTBE to gasoline to fight pollution _ a requirement that costs as much as 8 cents a gallon _ under rules announced Wednesday by the Environmental Protection Agency.
They eliminate a mandate from the 1990 Clean Air Act that gasoline used in metropolitan areas with the worst smog contain 2 percent oxygen by weight. The law did not say which oxygenate must be used, but most refiners use either ethanol or methyl tertiary butyl ether, known as MTBE.
