Federal Appeals Court Allows Cardinal-Hickory Creek Transmission Line Project to Move Forward

A federal appeals court this week lifted a court order that would have temporarily blocked the final phase of a controversial transmission project.

In March, U.S. District Court Judge William Conley granted a request by conservation groups to temporarily block a proposed land swap. That order prevented the Cardinal Hickory Creek transmission project from crossing through a Mississippi River wildlife refuge.

The utilities behind the project appealed that decision in the U.S. Seventh Circuit Court of Appeals.

On Thursday, a three-judge panel on the Chicago appeals court said the injunction blocking the land swap was not justified.

The appeals court said Conley needed to show that the National Wildlife Refuge Association, Driftless Area Land Conservancy and Wisconsin Wildlife Federation were likely to succeed in their lawsuit challenging the project. The court said he failed to do so.

“Instead the district court expressed concern that private parties might begin to build a transmission line before the court could address the merits,” the appeals court wrote.

The Cardinal-Hickory Creek transmission line runs more than 100 miles from Dane County to Dubuque County in Iowa. The first half of the project came online in December 2023.

ITC Midwest and Dairyland Power Cooperative, the co-owners of the Cardinal Hickory Creek line, said in a statement they were pleased with the appeals court’s decision.

They said the district court has stalled the line’s completion by blocking the utilities from exchanging land with the U.S. Fish and Wildlife Service. They said the land exchange was needed to finish a 1.1 mile segment near the Upper Mississippi River National Wildlife and Fish Refuge.

“The key effect of the appeals court order is that the government and utilities are now free to complete the land exchange,” the utilities said in a statement.
