U.S. Court Tosses Trump-Era Rule Expanding Sales of Corn-Based Ethanol

Jul 06, 2021

A federal appeals court on Friday struck down a U.S. rule put in place under former President Donald Trump to expand sales of corn-based ethanol, drawing ire from farm and biofuel groups that vowed to work to ensure that such sales continue.

The U.S. Court of Appeals for the District of Columbia Circuit ruled that the Environmental Protection Agency (EPA) exceeded its authority by lifting summertime restrictions on the sale of a 15% ethanol fuel blend known as E15. The decision came in a lawsuit by an oil refining trade group challenging the rule.

The EPA in 2019 extended a waiver that allowed year-round sales of E15. Ethanol producers cheered that move, as it would allow expanded sales of the blend.

The American Fuel and Petrochemical Manufacturers (AFPM), which sued the EPA, welcomed the D.C. Circuit’s ruling.

“There is no ambiguity in statute and the previous administration’s reinterpretation overstepped the will of Congress,” AFPM President Chet Thompson said in a statement.

Video: Turning Better Feed Into Better Herds: Innovation in Forage Harvesting

What happens when a dairy farmer gets frustrated with equipment that isn’t doing its job? In this episode, we sit down with Horning Manufacturing founder Leon Horning to hear how a problem in the feed bunk led to a globally recognized forage equipment company.

Born out of a third-generation dairy operation in Pennsylvania, Horning Manufacturing started with one goal: helping cows get more nutrition from silage. Leon shares how his father, Leon Sr., built the first kernel processor rolls in the family farm shop after seeing whole corn kernels pass through cows undigested — costing valuable feed efficiency and milk production.

We explore the company’s journey from a side project on the farm to an international manufacturer serving dairy farmers, beef operators, and custom harvesters around the world. Along the way, Leon discusses the evolution of pull-type forage harvesters, the engineering behind Horning’s “plug-and-play” kernel processor kits, and why reducing downtime during harvest can make or break a season.

The conversation also dives into Horning’s row-independent corn heads, practical equipment design, real-world customer stories, and how innovations born in the field continue to shape the company today.

Whether you’re a producer, equipment enthusiast, or simply love stories of grassroots innovation, this episode offers a fascinating look at how one farm family turned necessity into industry-changing technology.
