Groundwater Corrective Action

Alabama, Kentucky, and Tennessee

On December 19, 2025, the Tennessee Valley Authority (TVA) completed the final programmatic environmental assessment (PEA) for Groundwater Corrective Actions at one or more TVA fossil plants.

TVA has prepared a final PEA, pursuant to the National Environmental Policy Act (NEPA), to programmatically assess the effects of groundwater corrective actions implemented to address exceedances of groundwater protection standards.

As part of this programmatic assessment, TVA has developed new guidance, including an Environmental Screening Checklist and a bounding analysis, that complies with NEPA’s procedural requirements, up to and including potential site-specific considerations of groundwater corrective actions at one or more of these coal plants.

On August 18, 2025, the Tennessee Valley Authority (TVA) released the draft PEA for a 30-day public comment period.
