EPA Nears Key Decision on Biofuel Waivers for Oil Refiners The US government proposed a major increase in biofuels mandates earlier this year that would benefit farmers at the expense of oil refiners. Now the Trump administration is set to issue a second policy decision that could again shake up the renewable fuels market. The Environmental Protection Agency could rule as soon as this week on dozens of pending petitions from small oil refineries seeking exemptions from ethanol- and biodiesel-blending obligations from recent years, according to a person with direct knowledge of the matter who asked not to be named before a public announcement.
