EPA weighs refinery waivers of up to 1.8 billion RINs amid farm backlash

Summary

• Waiver expansion under consideration: The U.S. Environmental Protection Agency (EPA) is considering Small Refinery Exemptions (SREs) that could cover up to 1.8 billion renewable identification numbers (RINs), significantly above the roughly 1 billion RINs initially contemplated.
• Farm-state response: The Trump administration is considering ways to offset the impact on the agricultural sector, including potentially increasing 2027 renewable fuel volumes by roughly 500 million gallons or more.
• Fuel-price pressure: The debate pits refiners seeking relief from renewable-fuel compliance costs against farmers and biofuel producers concerned that broader exemptions could reduce demand for corn-based ethanol and soybean-based renewable fuels.

WASHINGTON, August 31, 2026 — The Trump administration is weighing a significant expansion of Small Refinery Exemptions under the federal Renewable Fuel Standard, with the Environmental Protection Agency potentially granting relief covering up to 1.8 billion renewable identification numbers (RINs).

The figure would be substantially higher than the roughly 1 billion RINs the EPA had initially been expected to cover. Reuters reported that industry representatives briefed on the administration’s plans expected the final exemptions to fall somewhere between 1.2 billion and 1.8 billion RINs. The EPA had not yet finalized the decisions as of Monday.

The agency has been reviewing 34 pending small-refinery exemption requests, with the decisions expected by the end of August. The White House has pushed for broader relief as gasoline prices have risen amid the continuing conflict with Iran and disruptions affecting global energy markets.

The potential exemptions have triggered opposition from agricultural and biofuel groups, which argue that reducing refinery obligations could weaken demand for ethanol and other renewable fuels and put pressure on corn and soybean markets.

Balancing refinery costs and farm demand

The Renewable Fuel Standard requires obligated refiners and importers to account for specified volumes of renewable fuel in the U.S. transportation fuel supply. Companies can meet their obligations through renewable-fuel blending or by acquiring RINs, which are credits generated when qualifying renewable fuels are produced and used under the RFS programme.

Small refineries can seek exemptions under the Clean Air Act if they demonstrate that compliance would cause disproportionate economic hardship. EPA evaluates individual petitions using statutory requirements and economic information, including consultation with the Department of Energy.

The issue has become particularly contentious because the EPA’s final 2026 and 2027 RFS rule established record renewable-fuel requirements while also incorporating a mechanism to reallocate some volumes associated with earlier small-refinery exemptions.

EPA’s March 2026 rule included 70% reallocation of certain small-refinery exemption volumes from the 2023-2025 compliance years. That mechanism was intended to prevent previously granted exemptions from permanently reducing the national renewable-fuel requirements.

White House seeks a farm-sector offset

The administration is now considering whether a similar approach could soften the impact of a larger new round of exemptions.

According to Reuters, officials are considering increasing future renewable-fuel requirements by roughly 500 million gallons or more in 2027 to compensate for some of the biofuel demand potentially lost through the expanded SREs.

Such an adjustment would provide additional future demand for renewable fuels, but farm and biofuel groups have argued that increasing future quotas would not necessarily compensate producers for the immediate effects of lower RIN demand.

The debate therefore involves two separate markets: the near-term value of compliance credits and the longer-term physical demand for renewable fuels.

RIN markets already under pressure

The uncertainty over the SRE decisions has already affected renewable-fuel credit markets.

RIN prices fell sharply after the EPA extended the September 1 compliance deadline for refiners and signalled that it would decide on long-pending exemption requests by the end of August. Conventional ethanol D6 RINs fell 34 cents to $1.75 on August 24, their lowest level since April 15, according to Reuters. Biomass-based diesel RINs were trading at about $1.92.

Market participants have been assessing how many RINs could effectively be removed from refiners’ obligations through the exemption process. Estimates of 1.2 billion to 1.8 billion RINs have therefore become an important reference point for the market, even though the final number remained undecided.

Pressure from the Farm Belt

Agricultural groups have warned that expanded refinery exemptions could reduce the amount of renewable fuel required in the transportation system.

The concern is particularly significant for the U.S. corn and soybean industries. Corn-based ethanol represents a major source of domestic biofuel demand, while soybean oil is an important feedstock for biomass-based diesel.

Farm-state lawmakers have consequently urged the administration to avoid reducing renewable-fuel demand through broad refinery exemptions. The issue is politically sensitive because the administration is attempting to maintain support among both energy producers and agricultural communities ahead of the November congressional elections.

EPA maintains authority over final decisions

Despite pressure from the White House, the EPA has said that it retains authority over the individual exemption decisions.

The agency told Reuters that it was not being directed by the White House on which individual waiver requests should be approved or denied and that no final decisions had been made at the time of the report.

That distinction is important because SREs are legally evaluated on a petition-by-petition basis rather than automatically granted to every small refinery.

Earlier this month, the EPA announced decisions on six individual SRE petitions covering the 2023 and 2024 compliance years. The agency granted one petition a full exemption, two partial exemptions and determined three petitions to be ineligible.

Why this matters

• Refinery compliance costs: Larger SRE volumes could reduce the number of RINs refiners need to acquire or generate to satisfy their renewable-fuel obligations.
• Biofuel demand: Broader exemptions could reduce near-term demand for ethanol and other renewable fuels, putting pressure on RIN values and agricultural commodity markets.
• Farm-sector protection: A potential increase in 2027 renewable-fuel volumes could partially offset the impact of the exemptions on future biofuel demand, although it would not necessarily replace lost near-term demand.
• Fuel-price politics: The administration is weighing refinery relief against the political and economic impact of higher gasoline prices amid the continuing Iran conflict and broader energy-market disruption.
• RFS uncertainty: The final number of exemptions will influence RIN markets, refiners’ compliance costs and the effective renewable-fuel demand outlook for the sector.

FAQs

Q1: What are Renewable Identification Numbers (RINs)?

RINs are compliance credits used under the U.S. Renewable Fuel Standard to demonstrate that obligated parties have met their renewable-fuel requirements. They are generated when qualifying renewable fuels are produced and used in accordance with the RFS programme.

Q2: What is a Small Refinery Exemption?

An SRE allows an eligible small refinery to receive relief from some or all of its RFS obligations if it meets the statutory requirements for demonstrating disproportionate economic hardship. EPA evaluates the petitions individually and consults with the Department of Energy.

Q3: Is EPA definitely granting 1.8 billion RINs in exemptions?

No. Up to 1.8 billion RINs was still a potential range under consideration as of August 31. Reuters reported that industry representatives expected the final number could be between 1.2 billion and 1.8 billion, while EPA said no final decisions had been made.

Q4: What is the proposed 500 million figure?

The administration is considering increasing 2027 renewable-fuel volumes by roughly 500 million gallons or more as a way of offsetting some of the impact of expanded refinery exemptions on the biofuel sector. This should not be described simply as 500 million RINs because gallons of renewable fuel and RIN credits are related but not interchangeable measures.

Q5: Why are farmers opposing broader refinery exemptions?

Farm and biofuel groups argue that lower refinery obligations could reduce demand for ethanol and renewable diesel feedstocks, including corn and soybean oil. They are concerned that lower biofuel demand could weaken agricultural commodity prices and rural-sector revenues.
