American Soybean Association Clears Up E15 Stance as Senate Debate Intensifies

The House vote to expand year-round E15 on Wednesday should have been a clean policy victory lap for ethanol supporters. Instead, it’s become a multi-layered debate involving competing economic models, social media confusion, and an increasingly complicated Senate runway that may determine whether the win in the House actually translates into law.

The House narrowly passed legislation Wednesday allowing year-round sales of E15, 218 to 203, marking a major win for ethanol advocates and corn growers. But that bill also included reallocation of Small Refinery Exemptions (SREs), which some groups say made the bill more complicated than just a straight bill that would clear the way for year-round sales E15.

But even as supporters celebrate, the conversation around what’s actually in the bill, and who benefits most, has only intensified.

And according to the American Soybean Association, much of the online backlash in recent days is rooted in a misunderstanding of the legislation itself.

“We Support Year-Round E15. 100%.”

ASA CEO Stephen Censky told Farm Journal the organization is not opposed to year-round E15.

“Absolutely. We have always supported year-round E15. We think it’s positive,” Censky says.

But Censky argues the social media controversy stems not from the ethanol provision itself, but from additional language in the House bill that deals with Small Refinery Exemptions (SREs) under the Renewable Fuel Standard.

“It’s those other provisions that provide exemptions to small refineries that undermine that positivity,” he says, also noting that multiple independent analyses suggest those provisions could shift the broader farm economy in less favorable ways.

FAPRI Study Adds Fuel Ahead of Vote

One of those studies came from the University of Missouri’s Food and Agricultural Policy Research Institute (FAPRI). Just ahead of the House vote, new modeling from FAPRI added fresh insight into the debate show that when you add in the reallocation of SREs, the House bill is a net negative for agriculture.

The analysis found that year-round E15 alone is relatively modest in its near-term market impact, largely shifting demand between corn and soybeans. But when paired with changes to Small Refinery Exemptions, the economic picture becomes more complicated.

“It takes what is really a trade-off between corn and beans and makes it an overall negative for both what the government spends and for the farm income for the sector,” says Seth Meyer, director of FAPRI.

NCGA Disputes Modeling Assumptions

After the report was released on Tuesday, groups like the National Corn Growers Association (NCGA) pushed back on the recent economic analysis by both FAPRI and the CBO.

NCGA Chief Economist Krista Swanson argued that key assumptions in the studies underestimate both policy strength and adoption speed.

“Year-round E15 saves drivers money at the pump, supports America’s corn farmers and improves energy security for our country,” she says, adding that the group’s own modeling shows stronger outcomes for farm income.

ASA Pushes Back on “Corn vs. Soy” Narrative

Even though controversy swirled on social media, claiming ASA’s lack of support for the House version of the bill shows a split between corn and soybean groups, Censky rejects the idea.

“No, I mean, again, I think that comes from a misunderstanding or maybe too simplistic of looking at things,” he says. “We support year-round E15, so does NCGA.”

He points to shared support from the NCGA, while emphasizing that the disagreement centers on refinery exemption language, not ethanol blending policy itself.

“It’s those other provisions (SREs) that were attached to that bill that we have the problems with,” he says,.

Senate Outlook: A Far More Complicated Road Ahead

If the House vote represented momentum, the Senate introduces a much higher degree of uncertainty.

Washington analyst Jim Wiesemeyer says the House approval was still a meaningful breakthrough for ethanol supporters, but the path forward now runs into procedural hurdles, committee jurisdiction battles and a Senate math problem that doesn’t easily resolve.

“Senate passage remains uncertain,” Wiesemeyer notes, pointing to the fact that Clean Air Act authority tied to E15 summer sales rests largely with the Senate Environment and Public Works Committee, not the Senate Ag Committee.

Wiesemeyer reports while Senate Majority Leader John Thune (R-S.D.) has expressed support for including year-round E15 in a broader farm bill effort, the jurisdiction split complicates the path forward. EPW Chair Shelley Moore Capito has supported compromise language similar to the House bill, but without the more controversial SRE-related reforms. Ranking Member Sheldon Whitehouse (D-R.I.), meanwhile, is expected to oppose expansion efforts tied to ethanol policy under Clean Air Act authority.

That leaves Senate Ag Chairman John Boozman (R-Ark.) in a key position, but without full control over the underlying regulatory levers.

But even Boozman was clear after the Senate vote that the House version could face resitance in teh Senate. Boozman, who akso serves as Chairman of the House Ag Committee, telling Politico the House version may not have enough support to make it through the upper chamber, saying after the vote, “I think we have a good chance to pass an E15 bill. I don’t know if it will be that one.”

Even if a path emerges through committee, Wiesemeyer notes that a stand-alone bill would still need 60 votes for cloture on the Senate floor, an uphill climb given opposition from refining-state senators and lawmakers concerned about emissions, fuel volatility, and air-quality standards.

That bipartisan resistance could force supporters to consider alternative strategies.

One option, according to Wiesemeyer, is something increasingly discussed in Washington: attaching year-round E15 to a must-pass legislative vehicle later this year, such as a broader energy package, government funding bill, or end-of-year omnibus-style agreement, where controversial policy riders are often resolved in larger negotiations.

For now, Wiesemeyer’s bottom line mirrors the broader tone emerging from both the economic analysis and the policy debate: the House delivered a meaningful win for ethanol supporters, but in the Senate, the path forward is anything but settled, and the final outcome is still very much in play.

Where the Uncertainty Really Sits

Much of the debate now centers on variables that remain unresolved: how quickly E15 is adopted, how EPA interprets Renewable Fuel Standard obligations, and how aggressively Small Refinery Exemptions are implemented in practice.

Those unknowns, analysts say, will ultimately determine whether the legislation is a modest reshuffling of crop demand or a more meaningful shift in long-term farm income trends.
