BILLINGS, Mont. >> The Biden administration on Thursday proposed a new permitting program for wind energy turbines, power lines and other projects that kill eagles, amid growing concern among scientists that the rapid expansion of renewable energy in the U.S. West could harm golden eagle populations now teetering on decline.

The Fish and Wildlife Service program announced Thursday is meant to encourage companies to work with officials to minimize harm to golden and bald eagles.

It’s also aimed at avoiding any slowdown in the growth of wind power as an alternative to carbon-emitting fossil fuels — a key piece of President Joe Biden’s climate agenda. It comes after several major utilities have been federally prosecuted in recent years for killing large numbers of eagles without permits.

The federal government already issues permits to kill eagles. But Thursday’s proposal calls for new permits tailored to wind-energy projects, power line networks and the disturbance of breeding bald eagles and bald eagle nests.

Fish and Wildlife Service Director Martha Williams said the new program would provide “multiple pathways to obtain a permit” while also helping conserve eagles, which she described as a key responsibility for the agency.

Bald eagle numbers have quadrupled since 2009 to about 350,000 birds. There are only about about 40,000 golden eagles, which need much larger areas to survive and are more inclined to have trouble with humans.

The number of wind turbines nationwide more than doubled over the past decade to almost 72,000, according to U.S. Geological Survey data, with development overlapping prime golden eagle territory in states including Wyoming, Montana, California, Washington and Oregon.

In April, a subsidiary of the Florida-based utility industry giant NextEra Energy pleaded guilty in federal court in Wyoming to criminal violations of wildlife protection laws after its wind turbines killed more than 100 golden eagles in eight states. It was the third conviction of a major wind company for killing eagles in a decade.

Federal officials won’t divulge how many eagles are reported killed by wind farms, saying it’s sensitive law enforcement information.

Nationwide, 34 permits in place last year authorized companies to “take” 170 golden eagles — meaning that many birds could be killed by turbines or lost through impacts on nests or habitat, according to permitting data obtained by The Associated Press. More than 200 permits were in place to allow the killing of 420 bald eagles, according to the data.

For each loss, companies are responsible for ensuring at least one eagle death is avoided somewhere else.
