US EPA wants to eliminate tougher limits on soot, but critics warn about health risks

The U.S. Environmental Protection Agency has asked a federal judge to overturn the 2024 soot limit for factories and power plants. Critics have called this a blatant retreat away from one of its most important public health protections in recent years.

In a Monday filing, the EPA sided up with 24 states, led by Kentucky, and industry groups, including the National Association of Manufacturers, who sued the EPA in order to overturn the 2024 standard for fine particulate matters, also known as PM2.5. Nearly 91% coal plants currently in operation already meet the new standard.

Soot is linked to cardiovascular disease, asthma and other health problems. Last year, the EPA, under the leadership of President Joe Biden, said that a tighter standard of 9 micrograms of soot per cubic meter could prevent more than 800,000. This would include 2,000 hospitalizations and 4,500 premature death.

The EPA, under the administration of President Donald Trump’s Lee Zeldin, did not reply to a question about its future plans.

In March, the Trump administration targeted soot among dozens of other regulations that it intended to repeal. The agency announced in a series of press releases that it had taken more than 30 deregulation measures.

Rolling back soot limitations would benefit the country's dirtiest power plants. The EPA claims that the Colstrip Power Plant, located in Montana is the only coal plant in the United States without pollution controls.

Environmental groups criticized the decision to abandon the stricter EPA standard for soot.

In this case, it was for one the most significant actions taken by the agency in recent years to safeguard public health." (Reporting and editing by Howard Goller; Valerie Volcovici)
