Q: RFS Reform Act of 2015 This bill amends the Clean Air Act to revise the renewable fuel standard program. Beginning on January 1, 2015, the renewable fuel that is required to be blended into gasoline must be advanced biofuel, which cannot be ethanol derived from corn starch. This bill revises the renewable fuel standards by decreasing the total volume of renewable fuel that must be contained in gasoline sold or introduced into commerce for years 2015 through 2022. The Environmental Protection Agency (EPA) must determine the target amount of cellulosic biofuel to be blended into transportation fuel based on the actual volume of cellulosic biofuel produced in the current year. The EPA must reduce the required volume of renewable fuel in transportation fuel by the same volume of cellulosic biofuel in the fuel. The EPA may not allow gasoline containing greater than 10% ethanol by volume to be introduced into commerce. Waivers that allow gasoline containing a greater percentage of ethanol are nullified.
