Overview
- The EPA, which unveiled the proposal Thursday, would replace some one-size-fits-all discharge caps with case-by-case permits for wastewater from coal-fired plants.
- The agency says easing the rule will support the power grid and lower generation costs, citing up to $1.1 billion in annual savings as electricity use climbs with AI and data centers.
- The 2024 rule targeted toxic metals and other pollutants and was projected to cut 660 to 672 million pounds of discharges each year with a compliance deadline through December 31, 2029.
- Environmental groups, led by Earthjustice, warn the draft would boost toxic releases and allow contaminated groundwater that seeps into waterways to go untreated unless it is pumped to the surface.
- Coal and power industry trade groups praised the plan, which now heads into a public comment process that could set up court challenges before any final rule takes effect.
