The Environmental Protection Agency plans to waive a requirement that would have required Salt Lake, Davis and Weber county residents to use oxygenated gasoline in their vehicles this winter.
But the state was still going ahead with a formal hearing Wednesday on its proposal to ask the EPA to do just that.Oxygenated fuel is supposed to cut down on carbon monoxide pollution. But the three northern Utah counties haven't violated CO requirements recently; instead, they have a problem with fine particulates, or PM10, which may increase with the use of oxygenated fuel.
Therefore, state officials were planning once again to ask the EPA to waive the oxyfuel requirement for the three counties this winter. This would be the second year for the waiver.
