January 28 marked the end of the public comment period for EPA's proposed 16 percent cut for renewables production this year.
If allowed to unfold as written by Congress, the renewable fuel standard would have mandated the production of biofuels this year beyond the so-called blend wall, at more than ten percent of the total fuel supply.
EPA has claimed that the industry can't make enough biofuel at the right volumes and that cars cannot use higher blends of ethanol.
Opponents of the proposal disagree. They say EPA does not have the authority to reduce the RFS.
