"WASHINGTON — The Environmental Protection Agency plans to unveil a major new regulation on Monday that forces oil refiners to strip out sulfur, a smog-forming pollutant linked to respiratory disease, from American gasoline blends, according to people familiar with the agency’s plans."
"When burned in gasoline, sulfur blocks pollution-control equipment in vehicle engines, which increases tailpipe emissions linked to lung disease, asthma, emphysema, chronic bronchitis, aggravated heart disease and premature births and deaths. Proponents of the rule say it will be President Obama’s most significant public health achievement in his second term, but opponents, chiefly oil refiners, say it is unnecessarily costly and an unfair burden on them.
The E.P.A. estimates that the new rule will drastically reduce soot and smog in the United States, and thus rates of diseases associated with those pollutants, while slightly raising the price of both gasoline and cars. The rule will require oil refiners to install expensive new equipment to clean sulfur out of gasoline and force automakers to install new, cleaner-burning engine technology."
