"The Obama administration on Monday announced new fuel and automobile rules to cut soot, smog and toxic emissions, which it says will reduce asthma and heart attacks in the United States."

"The so-called Tier 3 rules unveiled by the Environmental Protection Agency have been under development since President Barack Obama issued a memorandum instructing the agency to develop them in 2010.

The rules, the third tier in a series of standards, will cut gasoline sulfur levels by more than 60 percent and should also reduce tailpipe and evaporative emissions from cars, light and medium-duty trucks and some heavy-duty vehicles.

Health advocates praised the move, while a petroleum refiners' group called the compliance schedule "unrealistic" and warned of potential supply disruptions."
