- Removing and consolidating approximately 2.5 million cubic yards of ash from the embayment. All the ash will be consolidated on-site in the re-engineered TVA coal ash disposal area.
- Building a protective perimeter dike by placing dry ash atop an engineered base layer of sand, gravel, and geofabric. The dry ash will be placed into the on-site disposal area slowly so that it does not slide. A new dike will be installed around the entire perimeter of the coal ash disposal area to keep the ash from entering the embayment in the future. The coal ash area will incorporate measures to divert drainage and control runoff.
- Closing the disposal area once all the ash has been put in place by putting a 2-foot clay cover and 1-foot of topsoil over it. Vegetation will then be planted to prevent erosion.
- Restoring the ecosystem to native sediments following the removal of the ash.
Drinking water, river water, and groundwater in the area will continue to be sampled on a routine basis.
