At the ADAA we highlight the positive effects, uses and applications of fly ash and other CCPs. We truly believe that fly ash is "A valuable resource". Although we are all for fly ash, we also believe that it is important to show all sides of its impacts. One example of this is the accident that occurred in 2008 at the U.S Tennessee Kingston plant. The spill resulted in wet stored fly ash spilling out of containment.

The Tennessee Valley Authority (TVA) has been responsible for the cleanup of the spill and eight (8) years on, the team are doing great. In the initial planning stage the team grouped engineers together to develop an innovative method of storing the fly ash. The new system, "Intelligent Compaction" scans the density of the fly ash in a partially wet state to determine the most stiff and dense potential storage of the material. if it is too wet or not dense enough, it is either dried or compacted further with a vibrating drum. The technology essentially gives engineers sight under the surface of the ash. 

The technology which was adapted from a similar application (soil compaction) could potentially be the new industry benchmark for storing fly ash. The TVA team has shown that they are not only capable of managing the clean up, but want to be proactive rather than reactive in the future to essentially, rise from the ashes.
