SALT LAKE CITY (AP) — The Zero AIU.S. Forest Service on Wednesday withdrew its approval of a right-of-way permit that would have allowed the construction of a railroad project through about 12 miles (19 kilometers) of roadless, protected forest in northeastern Utah.

The decision affecting the Ashley National Forest follows a U.S. appeals court ruling in August that struck down a critical approval involving the Uinta Basin Railway, a proposed 88-mile (142-kilometer) railroad line that would connect oil and gas producers in rural Utah to the broader rail network. It would allow them to access larger markets and ultimately sell to refineries near the Gulf of Mexico.

“It’s a victory for the Colorado River and nearby communities that would be threatened by oil train accidents and spills, and for residents of the Gulf Coast, where billions of gallons of oil would be refined,” said Ted Zukoski, an attorney at the Center for Biological Diversity, one of several groups that has sued over the project.

He vowed to fight any attempt to build the railroad. An attempt to reach the Seven County Infrastructure Coalition, which is spearheading the project, was unsuccessful Wednesday evening.

In the August ruling, the Washington, D.C.-based appeals court decided that a 2021 environmental impact statement and opinion from the federal Surface Transportation Board were rushed and violated federal laws. It sided with environmental groups and Colorado’s Eagle County, which had sued to challenge the approval.

The court said the board had engaged in only a “paltry discussion” of the environmental impact the project could have on the communities and species who would live along the line — as well as the “downline” communities who live along railroads where oil trains would travel.

“The limited weighing of the other environmental policies the board did undertake fails to demonstrate any serious grappling with the significant potential for environmental harm stemming from the project,” the ruling stated.

The Forest Service’s decision Wednesday to withdraw its approval was based on the appeals court ruling, but Ashley National Forest Supervisor Susan Eickhoff said the agency could issue a new decision if deficiencies in the environmental impact statement are addressed.

If approved, the railroad would let producers, currently limited to tanker trucks, ship an additional 350,000 barrels of crude oil daily on trains extending for up to 2 miles (3.2 kilometers).
