The Latest: New York state to sue over Trump’s new coal rule

The Latest on an environmental rule covering coal-fired power plants (all times local):

11:30 a.m.

New York’s attorney general says the state will sue to block the Trump administration’s rollback of an Obama-era rule designed to wean the nation’s electrical grid off coal-fired power plants and their climate-damaging pollution.

Attorney General Letitia James announced the state’s intentions on Twitter shortly after the Environmental Protection Agency replaced the rule with a less ambitious one. She makes reference to the administration’s “#DirtyPower rule.”

She tweets that it’s “another prime example of this administration’s attempt to rollback critical regulations that will have devastating impacts on both the safety & health of our nation.”

The Trump administration says the Obama administration overstepped its legal authority in approving the Clean Power Plan. EPA chief Andrew Wheeler says coal is essential to the nation’s power grid.

House Speaker Nancy Pelosi says the Trump administration’s rollback of a rule targeting coal-fired power plants is “a stunning giveaway to big polluters.”

Pelosi says in a statement that climate change is “the existential threat of our time” and that the administration is ignoring scientific studies about climate change and yielding to special interests.

Pelosi is reacting to Environmental Protection Agency chief Andrew Wheeler’s scrapping of the Obama-era Clean Power Plan, which sought to reduce the country’s reliance on coal and move to renewable energy sources. Wheeler replaced it with a less ambitious rule.

The administration argues that Obama’s EPA overstepped its legal authority in approving the Clean Power Plant rule.

The Trump administration has rolled back a landmark Obama-era effort targeting coal-fired power plants and their climate-damaging pollution.

It’s replacing the Obama rule with a less ambitious one that gives states more discretion in regulating those power plants.

Environmental Protection Agency chief Andrew Wheeler says it’s a sign that “fossil fuels will continue to be an important part of the mix” in the U.S. energy supply.

President Donald Trump campaigned partly on a pledge to bring back the U.S. coal industry, which has been hit hard by competition from cheaper natural gas and renewable energy.

The rule will go into effect shortly after publication in the Federal Register. Environmental groups pledge court challenges.

The Trump administration is close to completing one of its biggest rollbacks of environmental rules.

Lawmakers, environmentalists and others are readying for an announcement about a replacement for an Obama-era regulation that sought to limit coal-fired plants in the nation’s electrical grid.

The Clean Power Plan was one of President Barack Obama’s signature efforts to curb climate-changing emissions.

Critics of the Obama administration say it overstepped its legal authority in issuing the power plant rule. Those opposing the rollback say it will worsen climate change and increase deaths from coal-plant pollution.
