The Trump administration has decided not to appeal a court ruling that would sharply reduce its use of waivers exempting refineries from the nation's biofuels regulation, cheering the corn lobby but drawing anger from oil refiners.
The administration had until the end of March 24 to file a challenge, but by early March 25, no such filing had been entered, according to a case docket on the U.S. government's electronic-access service for court records.
Officials for the Environmental Protection Agency and the White House did not respond to requests for comment on Wednesday.
The decision appears to end a yearslong battle between the rival oil and corn industries, two critical political constituencies for President Donald Trump, over the waiver program.
Refiners argue the waivers are critical to keeping small refining facilities in business, but agriculture representatives said they have been overused and hurt farmers by eroding demand for corn-based ethanol.
The EPA's decision not to appeal the court ruling on refinery waivers was applauded by Minnesota's ethanol industry.
"It's very good news," said Brian Kletscher, board president of the trade group Minnesota Bio-Fuels Association and CEO of Highwater Ethanol in Lamberton, Minn. "We are thrilled about it. … It's not only good news for the ethanol industry, but for the agricultural industry and [corn] farmers as they go into planting season."
Minnesota is the nation's fourth-largest ethanol-producing state with 17 operating plants. The industry has been reeling in Minnesota and across the country for well more than a year, with many ethanol companies mired in red ink, some to the point of shutting down. Corn Plus, a good-size ethanol cooperative in the southern Minnesota town of Winnebago, closed in September.
