Trump EPA Moves to Deregulate Coal Ash, Sparking Clash Between Industry and Health Researchers

A Pivot Toward ‘Energy Dominance’
The U.S. Environmental Protection Agency (EPA) has ignited a sharp divide between industrial interests and public health advocates following a virtual public comment hearing regarding the rollback of coal ash regulations. The Trump administration is moving to dismantle key components of a 2024 Biden-era rule, specifically targeting the requirements for monitoring toxic residues at inactive coal plants and loosening the standards for groundwater protection near these sites.
EPA Administrator Lee Zeldin has framed these adjustments as “commonsense changes,” arguing that the move strengthens “cooperative federalism” by shifting oversight from the federal government to individual states. According to Zeldin, the shift is essential to restoring American energy dominance and accommodating the unique operational circumstances of specific facilities. However, the practical effect of the proposed rule would exempt various coal ash storage sites from federal regulation, potentially allowing power plant owners to delay or entirely avoid the remediation of toxic waste.
The Industrial Argument: Waste as a Resource
For the coal and construction industries, the residue left behind by burning coal—known technically as coal combustion residuals—is not merely waste, but a valuable industrial feedstock. During the hearing, the American Coal Ash Association and the American Cement Association pushed for a fundamental reclassification of the material.
John Ward of the American Coal Ash Association characterized the residue as an “underutilized domestic mineral resource,” suggesting that eliminating the restrictive criteria for “beneficial use” would streamline the production of cement, wallboard, and agricultural products. Leah Pilconis, vice president of government affairs at the American Cement Association, noted that coal ash improves the durability and strength of concrete. As the supply of fresh coal ash declines due to the transition away from coal-fired power, the industry is lobbying to treat this material as a production component rather than industrial waste to ensure continued access to legacy residues.
The Toxic Reality: Groundwater and Neurobiology
While industry leaders see a mineral resource, environmental lawyers and scientists see a public health crisis. Coal ash contains a potent cocktail of heavy metals, including arsenic, lead, and mercury. A 2022 study conducted by Earthjustice and affiliated groups indicated that over 90 percent of U.S. coal power plants were actively contaminating groundwater through these residues.
The danger is not static. Jennifer Cassel, an attorney with Earthjustice, testified that the risk is being amplified by climate change, as more frequent and severe hurricanes and rainfall events flush these toxins into local water supplies. She described the resulting pollution as a “tea” of contaminants that persists in communities surrounding these dumps, where residents report cancer clusters at rates far exceeding national averages.
The Impact on Pediatric Health
Perhaps the most jarring testimony came from Kristina Zierold, a professor at the University of Mississippi. Backed by a National Institutes of Health (NIH) grant, Zierold’s research since 2011 has focused on the neurobiological effects of coal ash on children aged 6 to 14. Her findings suggest a direct correlation between coal ash exposure and impaired cognitive performance and increased rates of depression in children.
Zierold’s team utilized air pollution and dust sampling within homes to track exposure, noting that the developmental delays and mental health struggles associated with these toxins can have “cascading effects” that follow a child into adulthood. Her testimony challenged the EPA’s “commonsense” framing, posing a direct question about the morality of allowing children to breathe or play in environments contaminated by industrial byproduct.
Regulatory Friction
The tension now rests on whether the EPA will prioritize the economic efficiency of the cement and coal sectors or the long-term health data provided by federal grants and environmental litigation. By shifting enforcement to the states, the administration is betting that local oversight will be sufficient, while critics argue this creates a regulatory vacuum that polluters will inevitably exploit.
