Easing refining restrictions
Refineries seem to be in a perpetual mess. They currently have to make over 40 types of gasoline blends to meet clean air requirements in different areas, and a new one hasn't been built in this country in over 30 years.

Easing clean air requirements or reducing the number of blends made might bring down prices. And there have been plans floated to require the industry to build more refineries.

But the industry says making all those different blends actually doesn't cost that much more money. And other analysts say refiners are barely turning a profit using the refining capacity they currently have, as gasoline prices have not risen as much as the price of crude oil.
