DES MOINES, IOWA (March 31, 2021) — Attorney General Tom Miller has filed an amicus brief in the US Supreme Court supporting several renewable fuels and agricultural associations in their challenge to the EPA’s award of small-refinery exemptions to the Renewable Fuel Standard.

AG Miller and Nebraska AG Doug Peterson organized and led a bipartisan coalition of eight state attorneys-general to join in the brief.

“The EPA’s practice of freely granting exemptions to the oil industry has undermined the promise of renewable fuels and harmed Iowa’s farmers and biofuels industries,” AG Miller said. “I’m grateful that a bipartisan coalition of states has joined us in this effort.”

Miller filed the brief in HollyFrontier Cheyenne Refining, LLC v Renewable Fuels Association. The case asks the Supreme Court to decide the EPA’s authority to grant small-refinery exemptions to the Renewable Fuel Standard, which requires increasing use of ethanol, biodiesel, and other renewable fuels.

The RFS exempted certain small refineries from complying with its requirements to blend renewable fuels into their gasoline or diesel fuel and gave EPA authority to extend the exemptions based on disproportionate economic hardship. Beginning in 2017, the EPA began granting a surge of small-refinery exemptions that devastated demand for renewable fuels, causing ethanol and biodiesel plants to slow, idle, or close.

A coalition of biofuels associations challenged the award of new exemptions to three small refineries that had not previously and continuously received the exemptions. In January 2020, the Tenth Circuit agreed, concluding that the EPA had authority only to grant extensions to a refinery that continuously maintained the exemption.

In the brief, AG Miller argues that the Tenth Circuit got it right. The plain language of the statute limits EPA’s authority to grant the exemption. And the more-expansive interpretation pushed by the small refineries would gut the RFS, the brief says. He also explains how an ineffective RFS would cause substantial economic harm to the rural economies of Iowa and other states, hurt the environment, and hamper efforts to move toward energy independence.

The full brief is available on the US Supreme Court’s website.

In February 2021, the EPA and the Biden administration announced it supported the Tenth Circuit’s decision, and the Justice Department submitted a brief in support.

As AG Miller’s brief notes, Iowa is the N° 1 renewable-fuel-producing state in the nation. In 2020, the renewable-fuel industry accounted for $4 billion — about 2% — of the state’s GDP, supported more than 37,000 jobs, and generated $1.8 billion of household income.

Yet the small-refinery exemptions have reduced the RFS mandate by an average of 7% each year from 2017 through 2019 — causing more than $2 billion in lost demand for renewable fuel nationally each year.

In addition to Iowa and Nebraska, Miller’s brief was joined by Illinois, Michigan, Minnesota, Oregon, South Dakota, and Virginia.

The case will be argued before the Supreme Court by telephone conference at 9AM Central time on April 27. A decision is expected by the end of June.
