The Environmental Protection Agency unveiled a proposal Thursday to weaken federal protections against toxic coal ash disposal, reversing course from stricter standards put in place during the Biden years.
The rollback focuses on three key areas: groundwater monitoring near coal ash storage sites, cleanup requirements for contaminated properties, and reuse of coal ash in other applications.
Under the new proposal, the EPA would reduce groundwater protection standards at some facilities and allow companies to target cleanup efforts to only the specific locations where ash was deposited rather than requiring remediation across entire coal plant properties. The changes would also clear regulatory barriers to repurposing coal ash in construction materials and other products.
Environmental advocates argue the relaxed rules create unnecessary risk. They contend that weakened monitoring and less comprehensive cleanup could allow hazardous pollutants to seep into drinking water supplies and increase public exposure to toxic materials left behind by coal combustion.
The move represents a sharp departure from the stricter regulatory approach the Biden administration adopted as part of a broader effort to restrict pollution emissions from coal-fired power plants. Those earlier rules were designed to tighten controls on where and how coal ash could be stored, setting more demanding standards for preventing groundwater contamination.
The proposal reflects the Trump administration's stated goal of reducing regulatory burdens on industry. Environmental groups are expected to challenge the rollback during a public comment period, though the agency's regulatory direction suggests momentum toward implementation.
