Trump EPA moves to abandon rule that sets tough standards for deadly soot pollution

WASHINGTON (AP) – The Trump administration is seeking to abandon a rule that sets tough standards for deadly soot pollution, arguing that the Biden administration did not have authority to set the tighter standard on pollution from tailpipes, smokestacks and other industrial sources.

The action follows moves by the administration last week to weaken federal rules protecting millions of acres of wetlands and streams and roll back protections for imperiled species and the places they live. In a separate action, the Interior Department proposed new oil drilling off the California and Florida coasts for the first time in decades, advancing a project that critics say could harm coastal communities and ecosystems.

The Environmental Protection Agency finalized a rule last year that imposed strict standards for soot pollution, saying that reducing fine particle matter from motor vehicles and industrial sources could prevent thousands of premature deaths a year.

Twenty-five Republican-led states and a host of business groups filed lawsuits seeking to block the rule in court. A suit led by attorneys general from Kentucky and West Virginia argued that the EPA rule would raise costs for manufacturers, utilities and families and could block new manufacturing plants.

In a court filing this week, the EPA essentially took the side of the challengers, saying the Biden-era rule was done “without the rigorous, stepwise process that Congress required” and was therefore unlawful.

“EPA now confesses error and urges this Court to vacate the Rule” before Feb. 7, the agency said in a brief filed with the U.S. District Court of Appeals for the District of Columbia Circuit. Vacating the Biden-era rule would revert the soot standard to a level established a dozen years ago under the Obama administration. The Trump EPA is set to propose its own rule early next year.

Environmental groups said the agency’s action – which follows a pledge by EPA Administrator Lee Zeldin to roll back the soot rule and dozens of other environmental regulations – threatens public health and undermines its obligations under the Clean Air Act.

“EPA’s motion is a blatant attempt to avoid legal requirements for a rollback, in this case for one of the most impactful actions the agency has taken in recent years to protect public health,” said Hayden Hashimoto, an attorney at the nonprofit Clean Air Task Force.

The 2024 rule set maximum levels of 9 micrograms of fine particle pollution per cubic meter of air, down from 12 micrograms established under former President Barack Obama. The rule sets an air quality level that states and counties must achieve in the coming years to reduce pollution from power plants, vehicles, industrial sites and wildfires.

“An abundance of scientific evidence shows that going back to the previous standard would fail to provide the level of protection for public health required under the Clean Air Act,” Hashimoto said.

EPA said in creating the rule that the new standard would avoid 800,000 cases of asthma symptoms, 2,000 hospital visits and 4,500 premature deaths, adding up to about $46 billion in health benefits in 2032. Then-EPA head Michael Regan said the rule would especially benefit children, older adults and those with heart and lung conditions, as well as those living near highways, factories and power plants.

“Walking away from these clean-air standards doesn’t power anything but disease,” said Patrice Simms, vice president of healthy communities at Earthjustice, a nonprofit law firm that represents environmental groups in the legal case.

President Donald Trump “has made it clear that his agenda is all about saving corporations money,” Simms said, adding under Zeldin, the EPA “has nothing to do with protecting people’s health, saving lives or serving children, families or communities.”

Soot, made up of tiny toxic particles that lodge deep in the lungs, can result in severe health harms, including premature death, and comes from sources such as vehicle exhaust pipes, power plants, and factories.
