'Good News for Clean Air' as Court Rejects Trump EPA Bid to Ditch Coal Plant Soot Rule

A federal appeals court on Friday rejected the US Environmental Protection Agency's attempt to scrap a Biden-era rule tightening limits on harmful soot pollution spewed from coal-fired power plants and other sources.

In a unanimous ruling, a three-judge panel of the US Court of Appeals for the District of Columbia Circuit dealt a blow to President Donald Trump's deregulatory agenda by leaving intact a national soot standard enacted in 2024 that lowers the amount of fine particulate matter from power plants, factories, and vehicles from 12 to 9 micrograms per cubic meter.

"Soot, made up of tiny toxic particles that lodge deep in the lungs, results in severe health harms, including premature death, and comes from sources like vehicle exhaust pipes, power plants, and factories," the legal advocacy group Earthjustice explained.

The Environmental Protection Agency (EPA) under Administrator Lee Zeldin last year asked the appellate court to invalidate the soot rule, claiming that the Biden administration exceeded its authority and failed to take into account the economic cost of implementing the policy.

“Clean air is not a luxury. We are thrilled these vital air quality standards have been upheld by a federal court,” said Patrice Simms, vice president of Healthy Communities at Earthjustice. “The 2024 soot standard is a critical advancement for public health, projected to save thousands of lives every year. Lee Zeldin’s EPA must stop catering to polluters and must instead fulfill its mission to protect public health. The time for implementing the 2024 soot standard is now.”

Clean Air Task Force senior director of legal advocacy Shaun Goho also welcomed the ruling, saying: "Fine particulate matter standards provide critical public health protections. The court correctly rejected EPA’s about-face on the need for a stronger standard."

Katie Huffing, executive director of the Alliance of Nurses for Healthy Environments, called Friday's decision "a win for public health."

“Every day in practice, nurses witness and treat conditions made worse by soot pollution," she said. "From asthma exacerbations and chronic obstructive pulmonary disease to heart disease and preterm birth, nurses see the real-world health implications of toxic air pollution."

"The science shows stronger limits to reduce dangerous soot pollution provide significant health benefits for Americans, especially for those most vulnerable and those exposed to higher levels of particulate matter pollution," Huffing added. "We now urge EPA to fully implement the strengthened standard to ensure those health benefits are realized.”

Noha Haggag, senior attorney for the Environmental Defense Fund, said that “today’s federal court decision is good news for clean air in America and for the millions of people harmed by deadly soot."

“Soot can cause asthma attacks, lung cancer, and premature deaths," Haggag added. "The court’s rejection of the Trump administration’s attempt to eliminate our national health standards for soot will mean healthier, longer lives for people across the country.”
