To amend the renewable fuel program under the Clean Air Act to account for small refinery exemptions, and for other purposes.

This bill revises requirements for exemptions given to small refineries of crude oil under the renewable fuel program, which requires transportation fuel to contain a minimum volume of renewable fuel. Specifically, the bill requires the Environmental Protection Agency to ensure that exemptions granted to small refineries do not result in a reduction to the national quantity of renewable fuel required under the program.
