"U.S. EPA modified its proposed 2014 renewable fuel standard rule last year after the White House raised concerns about production targets being too high and based on unreliable analyses, according to documents from interagency reviews of the draft proposal."
"In response to those concerns, EPA added language to address the ethanol "blend wall" -- the limit to how much ethanol can be blended into gasoline -- and uncertainty over advanced biofuel production and the future of the biodiesel industry, documents show. But the agency stuck to its target originally proposed for overall renewable fuel production.
At the heart of White House concerns was how the proposal would affect the credits associated with renewable fuels -- known as Renewable Identification Numbers, or RINs -- that are available for refiners to buy and sell to meet their annual obligations for the renewable fuel standard (RFS)."
