The Trump administration has put one of the largest new water projects on the Colorado River on the fast track, raising concerns among environmentalists.

Utah first proposed building a 140-mile pipeline from Lake Powell on the Utah-Arizona border more than a decade ago. The plan, however, was waylaid by environmental and other reviews during the Obama administration.

But last fall, the Utah Division of Water Resources updated the proposal, removing a hydropower plant and cutting $100 million from its price tag.

The move also changed which federal agency had jurisdiction over it — from the Federal Energy Regulatory Commission to the Bureau of Reclamation.
