The U.S. Environmental Protection Agency is proposing stronger rules for wastewater from coal-burning power plants.

The EPA plans to update a 2020 rule that requires power plants to clean up their wastewater streams.

That includes the wastewater from flue gas desulfurization, or scrubbers that remove sulfur dioxide, water used to transport coal ash and water that contains combustion residuals.

It’s not immediately clear what impact the rule might have on power plants in West Virginia. But industry observers have said they expect some plants will shut down sooner rather than comply.

The West Virginia Public Service Commission has approved wastewater upgrades for several of the state’s coal-burning power plants under the 2020 rule, costing hundreds of millions of dollars to be paid by ratepayers.

The EPA is working on a related rule that allows power plants to retire in 2028 to stay in compliance with the new requirements.
