- 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 imposing stricter standards on soot pollution. The decision upheld a 2024 rule requiring a tighter annual limit of 9 micrograms of fine particle pollution per cubic meter of air, rejecting the EPA's claim that it exceeded statutory authority. The ruling supports public health benefits projected to prevent thousands of premature deaths and hospital visits.
