The U.S. Environmental Protection Agency says it will move forward with new standards for cleaner gasoline to cut pollution from cars.
The EPA was expected to announce Friday that the new rules would reduce the amount of sulfur in gasoline by two-thirds -- delivering an environmental benefit comparable to taking 33 million cars off the road.
Oil industry officials warn the new plan could add up to nine cents per gallon at the gasoline pump. They say upgrades at refineries, as well as compliance costs, would total more than $12 billion.
Government officials say the stricter sulfur standard in gasoline would only cost an extra penny per gallon. The EPA says some refineries can already meet the tighter standards, while the rest could do so with modest improvements.
Automakers are generally in favor of the new rule because they already have to meet similar requirements in California.
