The Environmental Protection Agency is taking its first major action to address toxic wastewater from coal-burning power plants, ordering utilities to stop dumping waste into unlined storage ponds and speed up plans to close leaking or otherwise dangerous coal ash sites.

Plants in four states will have to close the coal ash ponds months or years ahead of schedule, the EPA said Tuesday, citing deficiencies with groundwater monitoring, cleanup or other problems.

The actions mark the first time the EPA has enforced a 2015 rule aimed at reducing groundwater pollution from coal-fired power plants that has contaminated streams, lakes, and underground aquifers.

U.S. coal plants produce about 100 million tons (90 million metric tons) annually of ash and other waste.

The Obama administration regulated the storage and disposal of toxic coal ash for the first time, including a requirement to close coal-ash dumping ponds that were unstable or contaminated groundwater. The Trump administration weakened the Obama-era rule in 2020, allowing utilities to use cheaper technologies and take longer to comply with pollution reduction guidelines that are less stringent than what the agency originally adopted.

EPA Administrator Michael Regan said the actions announced Tuesday will ensure that coal ash ponds meet strong environmental and safety standards and that operators of industrial facilities are held accountable.

In separate letters sent Tuesday, EPA denied requests for extensions of coal ash permits by the Clifty Creek power plant in Madison, Indiana; James M. Gavin plant in Cheshire, Ohio; and the Ottumwa plant in Ottumwa, Iowa.

The Greenidge Generation plant in Dresden, New York, was ruled ineligible for an extension. The former coal plant now uses natural gas.

The H.L. Spurlock plant in Maysville, Kentucky, will be required to fix groundwater monitoring as a condition for continued operation of its coal ash pond, the EPA said.

Coal ash storage and disposal went largely unregulated until a 2008 spill at a Tennessee Valley Authority power plant in Kingston, Tennessee. A containment dike burst and flooding covered more than 300 acres (121 million hectares), dumped waste into two nearby rivers, destroyed homes and brought national attention to the issue.

The EPA on Tuesday reiterated its “consistently held position that surface impoundments or landfills cannot be closed with coal ash in contact with groundwater.’’ Limiting contact between coal ash and groundwater after closure is critical to minimizing contaminants released into the environment and will help ensure communities near the sites have access to safe water for drinking and recreation, the EPA said.
