WASHINGTON (AP) — The Trump administration is close to completing one of its biggest rollbacks of environmental rules, replacing a landmark Obama-era effort that sought to wean the nation's electrical grid off coal-fired power plants and their climate-damaging pollution. The final Trump administration replacement rule, expected as soon as this week, instead would give individual states wide discretion to decide whether to require limited efficiency upgrades at individual coal-fired power plants.
The Environmental Protection Agency said Administrator Andrew Wheeler would have a major policy announcement Wednesday but did not disclose the topic. Democrats, environmentalists, industry representatives and others, however, expect the final rule on coal plants.
Joseph Goffman, an EPA official under President Barack Obama, said he feared that the Trump administration was trying to set a legal precedent that the Clean Air Act gives the federal government "next to no authority to do anything" about climate-changing emissions from the country's power grid. The Obama rule, adopted in 2015, sought to reshape the country's power system by encouraging utilities to rely less on dirtier-burning coal-fired power plants and more on electricity from natural gas, solar, wind and other lower or no-carbon sources.
Burning of fossil fuels for electricity, transportation and heat is the main human source of heat-trapping carbon emissions. Supporters of the revised rule say the Obama-era plan overstepped the EPA's authority.
"This action is recalibrating EPA so it aligns with being the agency to protect public health and the environment in a way that respects the limits of the law," said Mandy Gunasekara, a former senior official at the EPA who helped write the replacement rule. She now runs a nonprofit, Energy45, that supports President Donald Trump's energy initiatives.
"The Clean Power Plan was designed largely to put coal out of business," Gunasekara said. Trump's overhaul is meant to let states "figure out what is best for their mission in terms of meeting modern environmental standards and providing affordable energy," she said.
Democrats and environmentalists say the Trump administration has repeatedly sought to use the power of government to protect the sagging U.S. coal industry from competition against cheaper, cleaner-burning natural gas and solar and wind power while ignoring scientific warnings about climate change. With coal miners at his side , Trump signed an order in March 2017 directing the EPA to scrap the Obama rule. It was one of the first acts of his presidency.
His pledge to roll back regulation for the coal industry helped cement support from owners and workers in the coal industry, and others. Despite his promise, market forces have frustrated Trump's efforts. Competition from cheaper natural gas and renewable fuel has continued a yearslong trend driving U.S. coal plant closings to near-record levels last year, according to the U.S. Energy Information Administration.
The final rule is expected to closely follow the draft released in August.
By encouraging utilities to consider spending money to upgrade aging coal plants, environmental groups argue, the Trump rule could prompt the companies to run existing coal plants harder and longer rather than retiring them. "It's a rule to increase emissions because it's a rule to extend the life of coal plants," said Conrad Schneider, advocacy director of the Clean Air Task Force. "You invest in updating an old coal plant, it makes it more economic" to run it more to pay off that investment.
An Associated Press analysis Tuesday of federal air data showed U.S. progress on cleaning the air may be stagnating after decades of improvement. There were 15 percent more days with unhealthy air in America both last year and the year before than there were on average from 2013 through 2016, the four years when America had its fewest number of those days since at least 1980.
Trump has repeatedly claimed just the opposite, saying earlier this month in Ireland: "We have the cleanest air in the world, in the United States, and it's gotten better since I'm president."
Along with an initiative requiring tougher mileage standards for cars and light trucks, the Clean Power Plan was one of Obama's two legacy efforts to slow climate change. The Trump administration also is proposing to roll back the Obama-era mileage standards, with a final rule expected shortly. Environmental groups promise court challenges to both rollbacks.
Trump has rejected scientific warnings on climate change, including a report this year from scientists at more than a dozen federal agencies noting that global warming from fossil fuels "presents growing challenges to human health and quality of life."
EPA's own regulatory analysis last year estimated that Trump's replacement ACE rule would kill an extra 300 to 1,500 people each year by 2030, owing to additional air pollution from the power grid.
