“If the Biden administration is under any illusions, this is now very much a national fight that people are going to be knowing more and more about,” said Bill McKibben, founder of the climate change group 350.org. “People are already flooding in from all parts of the country.”

Tribal and climate change organizations, as well as the Minnesota Department of Commerce, had asked the court to reject key approvals for the pipeline on the grounds that Enbridge’s oil demand projections did not meet legal requirements. However, the three-judge panel decided 2-1 to affirm the approvals, the Associated Press reported.

The pipeline’s challengers can appeal the ruling with the state supreme court.

The Line 3 replacement would carry Canadian tar sands oil and regular crude from Alberta to Enbridge’s terminal in Superior, Wisconsin. The project is nearly done except for the Minnesota leg, which is about 60 percent complete.

Opponents of the more than $7 billion project say the heavy oil would accelerate climate change and risk spills in sensitive areas where Native Americans harvest wild rice, hunt, fish, gather medicinal plants and claim treaty rights.

Calgary-based Enbridge says the replacement Line 3 will be made of stronger steel and will better protect the environment while restoring its capacity to carry oil and ensure reliable deliveries to U.S. refineries. It underwent a rigorous environmental permitting process. The old line currently runs at about half its capacity because it’s increasingly subject to corrosion and cracking.

Activists are vowing to keep up a summer of resistance against the project amid the escalating battle over energy projects and rising awareness that racial minorities suffer disproportionate harm from environmental damage. And they’re drawing parallels with the fight over the Dakota Access pipeline, which was the subject of major protests near the Standing Rock Reservation in the Dakotas in 2016 and 2017.

“Minnesota does not need this conflict. Minnesota has already had enough police problems, and we are very upset at the level of private security and police forces that are all over the north right now,” Winona LaDuke, executive director of the Indigenous-based environmental group Honor the Earth, told reporters on a conference call Friday. “For a Canadian corporation. So we’ll stand our ground … and more will be coming. Guaranteed.”
