The Environmental Protection Agency was hit with another lawsuit today over its emissions standards, this time challenging the agency’s heavy-duty vehicle emissions standards for model years 2027-2032.

The National Corn Growers Association, American Farm Bureau Federation, the Owner-Operator Independent Drivers Association, and the American Petroleum Institute filed the lawsuit in the D.C. Circuit Court of Appeals claiming EPA exceeded its authority with “targets that rely too heavily on electrification and do not fully appreciate the role low-carbon fuels like ethanol play in the transportation sector.”

“EPA has tried to impose a one-size-fits-all approach to addressing climate change by prioritizing electric vehicles over other climate remedies like corn ethanol,” said Minnesota farmer and National Corn Growers Association President Harold Wolle.

The groups also noted that EPA’s standard will put America’s farmers and their livestock at risk and would have a devastating impact on America’s truckers and the supply chain. “Small business truckers makeup 96% of trucking and could be regulated out of existence if the EPA’s unworkable heavy-duty rule comes into effect,” said Todd Spencer, president, Owner-Operator Independent Drivers Association.

This is the third lawsuit filed against EPA over its emissions standards in the past week.
