The Trump administration is moving to roll back stringent soot and greenhouse gas regulations imposed on U.S. coal-fired power plants, a policy shift designed to extend the lifespan of aging facilities and revive shuttered ones. The Environmental Protection Agency (EPA) announced plans to revisit 2024 pollution standards set under President Biden, which targeted particulate matter (soot) and emissions linked to climate change. This effort aligns with Trump’s executive orders prioritizing energy reliability and expanding fossil fuel production amid a declared national energy emergency.
Soot, a byproduct of coal combustion, poses significant health risks as fine particles can enter the bloodstream and brain. Despite 91% of coal plants already complying with Biden’s standards, the administration argues that loosening rules is necessary to address anticipated surges in electricity demand. The Colstrip plant in Montana—the nation’s only coal facility without modern soot controls—stands to benefit significantly. Operator Talen Energy, alongside 20 states, is challenging Biden’s rules in court, while Trump’s EPA has sought to delay legal proceedings to reassess the regulations.
