Diesel Rules NPR's John Nielsen reports the Environmental Protection Agency has decided to require refiners to cut back the amount of particulates, sulfur and nitrogen oxides in diesel fuel. The new rules will be a major change for the oil industry, which will have to make cleaner diesel fuel for trucks and buses. Environmentalists applaud the initiative, which is based on the agency's powers under the Clean Air Act. A public comment period is expected to draw lots of opposition to the rules from the oil industry.
