COLSTRIP, Mont. — Actions by President Joe Biden's administration that could hasten closures of heavily polluting coal power plants and the mines that supply them are reviving Republican rhetoric about a so-called ''war on coal'' ahead of the November election.
The front line in the political battle over the fuel is in the Powder River Basin of Wyoming and Montana, a sparsely populated section of the Great Plains with the nation's largest coal mines. It's also home to a massive power plant in Colstrip, Montana, that emits more toxic air pollutants such as lead and arsenic than any other U.S. facility of its kind, according to the Environmental Protection Agency.
The EPA last month finalized a suite of rules that could force the Colstrip Generating Station to shut down or spend an estimated $400 million to clean up its emissions within the next several years. Another proposal, from the U.S. Interior Department, would end new leasing of taxpayer-owned coal reserves in the Powder River Basin, clouding the future of mines including Westmoreland Mining's Rosebud Mine that provides about 6 million tons of fuel annually for Colstrip.
Eight years ago during his first White House run, Donald Trump stoked populist anger against government regulation by highlighting anti-coal measures taken under former President Barack Obama. The latest moves against coal have teed up the issue again for Republicans seeking to unseat Biden in the November election. Some coal-state Democrats also raised concerns.
''This onslaught of new rules is going to kill jobs and will kill communities like Colstrip,'' Montana Republican Sen. Steve Daines said during a visit to Rosebud Mine this week with Republican Gov. Greg Gianforte. ''What will change this outcome is an election and a new administration."
U.S. coal consumption dropped precipitously over the past decade as cheap natural gas and renewables expanded. Yet coal's political potency endures as detractors try to further curb burning of the fuel that's a major contributor to climate change and air pollution.
It remains an economic mainstay in communities such as Colstrip, generating jobs where workers can earn $100,000 annually, according to union officials.
The Biden administration defended the latest restrictions on coal as necessary to reduce harmful pollutants, improve public health and address court rulings over climate change.
