The U.S. Environmental Protection Agency wants a 97-percent reduction in sulphur from diesel fuel by the year 2006, and it's taking its proposal directly to the public. The second of five scheduled hearings on the issue will take place in Rosemont, Illinois, on Tuesday. At the first of the hearings -- conducted Monday in New York -- Margo Oge of the EPA said, "Anyone who has ever driven behind a bus or a truck is familiar with the smell of the diesel fuel and familiar with the cloudy emissions that come out from those trucks."
