A federal appeals court in Washington has rejected the Environmental Protection Agency’s bid under the Trump administration to abandon a 2024 rule that tightens limits on fine particulate, or soot, pollution across the United States. The regulation, adopted in 2024, was designed to reduce toxic industrial emissions and protect public health. EPA analyses projected the standard would prevent thousands of premature deaths and hospital visits annually. Republican-led states, led by West Virginia and Kentucky, had sued to strike down the rule, arguing it would harm economic growth. The court’s ruling requires the EPA to keep enforcing the stricter soot limits.
