Coal Combustion Residuals

Coal Ash

Our Commitment to You: Safe, Responsible Coal Ash Management

The Tennessee Valley is our home. We care about our neighbors and about protecting our air, land, and water resources.

TVA is committed to serving our communities through our mission of providing low-cost, reliable power, environmental stewardship, and economic development.

This commitment also includes the safe, responsible management of coal combustion residuals (CCR), or what is commonly referred to as coal ash, which is a byproduct of burning coal for electricity.

TVA is an Industry Leader in the Safe, Secure Monitoring and Management of Coal Ash

TVA is pioneering new technology and using the best science, data, and research to ensure our coal ash sites are safe and secure.

  • We designed the Advanced Technology for Impoundment Monitoring (ATIM) system, which is  the nation’s first and only one of its kind, that monitors our coal ash storage sites 24 hours a day, 365 days a year.
  • Our state-of-the-art water processing and treatment practices and robust network of groundwater monitoring wells ensure the protection of waterways and natural resources.
  • We use compaction technology and cutting-edge 3D technology to map each layer of coal ash that is placed into TVA’s dry storage landfills to further ensure the safety and stability of our sites.

TVA Works with Regulators to Ensure our Actions are Safe and Effective

TVA’s customized science-based monitoring and management plans for each of its coal ash sites across the Tennessee Valley meet or exceed regulatory requirements set forth by the Environmental Protection Agency (EPA) and state regulators.
