Trump EPA Weakens Mercury Rules for Coal Plants
The Trump administration’s Environmental Protection Agency announced plans to weaken mercury emission restrictions for coal-fired power plants, according to reporting on February 18, 2026. Senior EPA officials under Administrator Lee Zeldin were expected to announce the loosening of hazardous pollutant limits during a trip to Louisville, Kentucky on Friday, with the agency arguing the change would reduce costs for utility companies.
The EPA has already exempted 47 coal companies from mercury and air toxics regulations for two years and proposed repealing Biden-era rules limiting carbon dioxide, mercury, and other air pollutant emissions from power plants. The agency estimates the new restrictions would save companies as much as $670 million between 2028 and 2037, according to internal documents reviewed by the New York Times.
Mercury is a potent neurotoxin capable of impairing fetal brain development, and the rollback directly contradicts established science on public health harm. Trump declared an “energy emergency” to justify keeping aging coal plants operating and exempting them from critical air regulations, prioritizing coal industry interests over documented environmental and health protections established under previous administrations.
The administration has simultaneously dismantled renewable energy support by removing tax incentives for wind and solar projects and slow-walking permits for renewable energy development on federal, private, and state lands. This pattern reflects Trump’s stated goal of fast-tracking energy infrastructure to support artificial intelligence and data center demands while blocking clean energy alternatives.
The move represents a continuation of the administration’s broader effort to provide industrial polluters exemptions from emissions requirements for toxic chemicals, with the EPA establishing mechanisms for coal plants to request presidential waivers under the Clean Air Act framework.
