(NAFB) – Pro-ethanol forces are not giving up in their fight against EPA biofuel waivers, even after the Supreme Court’s June ruling, waivers need not be continuous.

Iowa Republican Randy Feenstra and Minnesota Democrat Angie Craig would refine the meaning of “extension” in the Renewable Fuel Standard to cover only waivers granted continuously, not lapsed ones, the Supreme Court allowed with its recent ruling.

Renewable Fuels Association chief Geoff Cooper on a recent press call.

Cooper argues refiners have had 15 years to comply with the RFS, but agrees the oil industry and its lobbyists will continue to fight biofuels in the political arena.

Nor will the fight over the Supreme Court ruling, both in Congress, and at EPA.

Cooper argues Biden’s EPA sided with a lower court against the waivers and can still use parts of that ruling to limit future waivers. However, Reuters reported recently a Delta Airlines refinery request is under active review.

And in another setback for the ethanol industry, a D.C. federal court Friday reversed the 2019 EPA rule that allowed year-round sale of E15 gas—a ruling ethanol and corn groups say could kill 90-percent of summertime sales, and one they could fight in and out of the courts.
