Court Upholds Tough Soot Pollution Rule
27 Jun
Summary
- A federal appeals court upheld a Biden-era rule on soot pollution.
- The ruling keeps in place a tighter annual limit of 9 micrograms per cubic meter of air.
- Environmental groups celebrated the decision as a victory for public health.

A federal appeals court on Friday maintained a stringent Biden-era standard for deadly soot pollution, denying the Environmental Protection Agency's effort to dismantle the rule. This unanimous decision by a three-judge panel thwarts attempts to weaken regulations on industrial emissions, particularly those from coal-fired power plants and factories.
The court's ruling preserves the annual limit of 9 micrograms of fine particle pollution per cubic meter of air, a reduction from the previous 12 micrograms. This standard mandates that states and counties work towards achieving cleaner air quality, addressing pollution from various sources including power plants, vehicles, industrial sites, and wildfires.
The EPA, under previous leadership, had sought to invalidate the rule, citing concerns over exceeding statutory authority and neglecting business costs. However, the court found these arguments lacked merit. Environmental organizations lauded the decision, asserting it is crucial for public health and will prevent numerous cases of asthma symptoms, hospital visits, and premature deaths annually.
