HARRISBURG, Pa. (AP) — The U.S. Environmental Protection Agency moved Thursday to roll back limits that require coal-fired power plants to prevent the release of toxic heavy metals into streams and rivers through polluted groundwater, saying a three-year-old rule is unduly costly for the energy industry at a time when energy demand is spiking.It is the latest step that President Donald Trump’s administration has taken to pull back regulations on coal mining and coal-fired power and empower fossil fuels as a primary energy source to feed the rapid growth of artificial intelligence data centers.In its proposed rule, the EPA said a 2024 rule under President Joe Biden misjudged the effectiveness and cost of the regulation, and had the effect of shutting down coal-fired power plants at a time when energy demand is spiking.Changing the rule is critical to making electricity more affordable and reliable, while advancing the economy, EPA Administrator Lee Zeldin said in a statement.

“The AI and data center revolution is creating an electricity and baseload power demand that cannot be met under the overly restrictive policies of past administrations,” Zeldin said. “The Trump EPA will continue doing its part to address these burdensome regulations on the coal-fired power plant sector that hold American communities back from the new opportunities presented by this new 21st century energy reality.”
