The embattled Environmental Protection Agency on Friday released proposed rules for the volume of biofuels to be blended into the nation’s fuels through 2016, and brought immediate complaints, the Washington Post reported. Some farm interests said the requirement didn’t go far enough, while oil interests considered a legal challenge to fight the proposal. The law sought to increase U.S. energy independence and also reduce greenhouse gas emissions, but lower gas prices have crimped plans. The proposed policy simultaneously increases conventional biofuel volumes (mostly comprised of corn-based ethanol) for 2016 to up to 14 billion gallons, less than the law had initially stipulated, 15 billion gallons. Total conventional biofuels used in 2014 amounted to about 13.25 billion gallons.
