The renewable fuels industry got some good news Monday when the U.S. Environmental Protection Agency (EPA) said it would tighten restrictions on small-refinery Renewable Fuels Standard (RFS) waivers. Those exemptions have been in place since 2010 and some refineries have leveraged them to all but opt out of the RFS in the decade that followed. Though the oil industry continues to appeal to the 10th Circuit and Supreme Court to uphold the waivers — which will be taken up by the Supreme Court in April — the announced change shows federal officials may be changing course on the RFS in general. An EPA statement Monday said the shift “reflects the Agency’s considered assessment that the Tenth Circuit’s reasoning better reflects the statutory text and structure, as well as Congress’s intent in establishing the RFS program.” See more on the RFS announcement.
