Morning update:

We had a well attended meeting tonight at the Roane County Courthouse. EPA's Craig Zoeller gave a good overview of the three EE/CA alternatives. TVA provided the CAG with a 3D flyby video that gave folks a better idea of what the site will look like when the smoke clears.

A problem with coal ash building up under docks just upstream of Kingston City Park was brought up by a homeowner. This problem will be looked into but several folks thought this area where the shore is exposed at low pond could be remediated. The homeowner also mentioned something far more disturbing that we need to carefully study: There were NO willow fly hatches in his area this past year. This could simply be a mechanical problem due to the amount of sediment or it could be a far more insidious problem due to selenium.

Questions were raised as to the fact that the proposed alternatives do not call for a liner underneath the coal ash, This would not be allowed under any permit application if this were a new landfill.

Water flow in and out of the proposed solutions continues to be questioned. The EE/CA alternatives have a cap that reduces rain water intrusion to a tenth of what the old facility had. This is good but does not address the issue of ground water flow or the issue of flow in and out of the dikes due to raising and lowering of the lake. This is much like the water table in tidal areas rising and falling with the tide even several miles inland. This would produce a continual flushing of the coal ash below stored at and below lake levels.

Have they decided

Have they decided on the best scientific procedures to find out just how much coal ash has migrated into the Clinch and Tennessee River systems? I know that this subject has been brought up more than once by several people. Last I heard, it was a "we'll have to decide on how to make that determination".
I think it is vital to know this before the river recrerational season starts.

Funny you should mention that...

I heard EPA's Craig Zoeller say that 600,000 cubic yards of ash would probably remain in the water and be studied. That's a new number and includes ash that is in the Emory that can't be dealt with, such as shallows in coves etc.

And Rick, The CAG misses your energy. We would love to have your contributions anytime you can join in the fun.

600,000 cubic yards

Isn't that enough coal ash to cover 7 square miles, 1 inch deep?

I am about 80% as to where I need to be. If all goes well, you all will have to put up with me again. I will be back soon. And thanks.
