There's a nice blog article from Jim Cahill on the blend wall at http://www.emersonprocessxperts.com/2013/01/addressing-the-renewable-fuel-standard-and-blend-wall/.  Here's an excerpt on the RFS program history.

The RFS program was created under the Energy Policy Act (EPAct) of 2005, and established the first renewable fuel volume mandate in the United States. As required under EPAct, the original RFS program (RFS1) required 7.5 billion gallons of renewable- fuel to be blended into gasoline by 2012.
Under the Energy Independence and Security Act (EISA) of 2007, the RFS program was expanded in several key ways:

• EISA expanded the RFS program to include diesel, in addition to gasoline;
• EISA increased the volume of renewable fuel required to be blended into transportation fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022;
• EISA established new categories of renewable fuel, and set separate volume requirements for each one.
• EISA required EPA to apply lifecycle greenhouse gas performance threshold standards to ensure that each category of renewable fuel emits fewer greenhouse gases than the petroleum fuel it replaces.

RFS2 lays the foundation for achieving significant reductions of greenhouse gas emissions from the use of renewable fuels, for reducing imported petroleum, and encouraging the development and expansion of our nation’s renewable fuels sector.
