Appeals court rejects Trump EPA bid to abandon rule restricting deadly soot pollution

A federal appeals court rejected the Trump administration's attempt to abandon a Biden-era rule that tightens soot pollution standards. The court found the EPA's arguments lacked merit, upholding a 9 microgram per cubic meter annual limit on fine particle pollution. The decision supports public health benefits projected by the Biden-era rule, which aims to reduce asthma cases and premature deaths.
