"10 acre interim storage area" approved that used to be called the Swan Pond embayment
"…approval of ash disposal transport to Perry County, AL, approval of a 10-acre interim storage area west of Dike 2, and TDEC approved dredge cell test plan. Railcars are currently being loaded. The first train left the site Thursday July 2nd. Crews will continue working through the weekend to load cars. A second train is anticipated to leave Saturday."
All in the "Pollution Report #22 TVA Kingston Fly Ash Release Time-Critical Removal Action" (link...)

At first, I thought this was just the approval for test loadings to the four landfills, but discusses other options including Midtown (too long to get permit), other previously unmentioned. …also details of test loading of trucks and trains.
Here is the documentation
