The White House is planning to unveil a proposal by the Environmental Protection Agency that aims to clean up gasoline and automobile emissions, a plan officials say will lead to cleaner air but also higher gas prices.
The so-called Tier 3 standards would reduce sulfur in gasoline by more than 60 percent and reduce nitrogen oxides by 80 percent, by expanding across the country a standard already in place in California. It would go into effect in 2017.
The oil industry, Republicans and some Democrats have pressed the EPA to delay the rule, saying it would be unwise to impose such a standard while many are still struggling in a bad economy. An oil industry study says the rule could increase gasoline prices by 6 to 9 cents per gallon.
The EPA says the potential increase in gas prices would be slight, estimating the rules could increase gas prices by less than a penny per gallon and add $130 to the cost of a vehicle in 2025. Additionally, the agency argues the plan will yield billions of dollars in health benefits by slashing smog- and soot-forming pollution come 2030.
