A decision by the Environmental Protection Agency to exempt 29 small refineries from nearly 1.8 billion renewable fuel credits is raising fresh concerns across farm country — but a commitment to put those credits back into the nation’s fuel-blending requirements could prevent a major hit to demand for corn ethanol and soybean-based biofuels.
EPA announced Monday that it had approved 29 small refinery exemption petitions covering 1.76 billion Renewable Identification Numbers, or RINs, for the 2025 compliance year.
RINs are essentially credits used to demonstrate compliance with the federal Renewable Fuel Standard. The program requires petroleum companies to blend renewable fuels — including corn ethanol, biodiesel and renewable diesel — into the nation’s fuel supply.
When a refinery receives an exemption, it does not have to meet some or all of those renewable fuel obligations.
That is why farmers and biofuel producers have been watching the EPA decision so closely.
The concern is simple: fewer obligations can mean less demand for renewable fuel and, ultimately, less demand for the corn and soybeans used to make it.
EPA granted full exemptions to 18 refineries and 50% exemptions to another 11. Three petitions were denied and two were ruled ineligible.
The 1.76 billion RINs exempted are significantly more than EPA originally anticipated.
Under its existing methodology, EPA had projected about 990 million RINs would be exempted for 2025. The actual number was roughly 770 million RINs higher.
That difference is now at the center of the administration’s effort to protect biofuel demand.
EPA says it will propose reallocating 100% of the exempted volume into the 2026 and 2027 Renewable Volume Obligations, or RVOs, before the end of October.
In practical terms, that means EPA intends to make other obligated petroleum companies pick up the renewable fuel volume that otherwise could have disappeared because of the refinery exemptions.
For farmers, that reallocation could be the difference between a temporary policy disruption and an actual reduction in the market for their crops.
Renewable Fuels Association President and CEO Geoff Cooper said the exemptions themselves are difficult to justify, but he credited EPA for taking steps to prevent a net loss in renewable fuel demand.
“While we continue to believe most of the SREs issued today are completely unjustified, we are somewhat encouraged that EPA is taking steps to minimize the damage through reallocation,” Cooper said.
The concern among biofuel advocates is particularly sharp because many refiners have reported strong financial results.
Growth Energy CEO Emily Skor questioned whether the refineries receiving exemptions have demonstrated the economic hardship required to qualify.
“It’s difficult to see how these refiners have met this threshold when they’re simultaneously reporting sky-high and, in some cases, record-setting earnings,” Skor said.
For corn farmers, the issue goes straight to one of the largest domestic markets for their crop.
The United States uses billions of bushels of corn every year to produce ethanol. That ethanol is then blended into gasoline, creating a major source of demand for U.S.-grown corn.
National Corn Growers Association President Jed Bower said farmers need strong markets for their crops, particularly at a time when agricultural producers are facing significant economic pressure.
“We need vibrant markets for our products, particularly when it comes to corn ethanol, and the nation’s drivers need affordable fuel,” Bower said.
Bower also argued that the large number of refinery exemptions has not proven to be an effective way to reduce gasoline prices.
The American Farm Bureau Federation echoed those concerns while expressing support for EPA’s reallocation plan.
Farm Bureau President Zippy Duvall said renewable fuels have become a major success story for rural America by supporting farm income, creating jobs, reducing dependence on foreign oil and helping provide lower-cost fuel to consumers.
“While we have concerns about granting any small refinery exemptions that undercut a strong domestic biofuels market for farmers, we are pleased to see EPA’s commitment to toward 100% reallocation of exempted volumes before the end of October,” Duvall said.
The soybean industry has even more at stake because soybeans are an important feedstock for biodiesel and renewable diesel.
The American Soybean Association estimates that without full reallocation, biomass-based diesel demand could fall by 500 million gallons, potentially costing soybean farmers nearly $1 billion in revenue.
That is why soybean growers are pressing EPA to move quickly.
“Any delay in reallocation risks undermining the domestic market demand that soybean farmers urgently need as we enter harvest season,” said Dave Walton, ASA vice president and an Iowa soybean farmer.
The soybean group also wants EPA to address potential increases in small refinery exemptions for 2026 and 2027 so farmers are not forced to revisit the same issue every year.
Meanwhile, producers of biodiesel, renewable diesel and sustainable aviation fuel say they are already operating at a rapid pace to meet federal renewable fuel requirements.
Kurt Kovarik of Clean Fuels Alliance America said producers are operating at record levels but remain concerned about the uncertainty surrounding the Renewable Fuel Standard.
The EPA has also pushed back the 2025 RVO compliance deadline by 30 days, moving it to Oct. 1, 2026, giving the market additional time to absorb the impact of the exemptions.
For farmers, however, the next major deadline is likely to be the end of October.
That is when EPA has pledged to complete supplemental rulemaking to restore the roughly 770 million RINs that exceeded its original 2025 exemption projection.
The outcome matters because RINs may sound like an industry-specific technical issue, but the consequences reach directly into farm country.
More renewable fuel demand means more demand for the corn and soybeans used to produce that fuel. Less demand puts additional pressure on crop markets.
That makes EPA’s next move just as important to farmers as Monday’s exemption announcement.
The Renewable Fuels Association, National Corn Growers Association, American Farm Bureau Federation and American Soybean Association all expressed some version of the same message: the exemptions are a disappointment, but full and timely reallocation could prevent the damage from spreading into the farm economy.
Now, farm and biofuel organizations will be watching EPA to make sure that commitment becomes reality.
The stakes are particularly high as farmers head into harvest.
For corn and soybean growers, this is no longer simply a debate over refinery regulations or federal fuel policy.
It is a question of whether the government will maintain one of agriculture’s largest homegrown markets — and whether the demand created by America’s renewable fuel policy will continue to translate into demand for crops grown on American farms.
