Q: Does the Allen Steam Plant not dispose of coal ash in a toxic slurry pit similar to the one which flooded many acres in the other end of the state? Hasn't this ash been deposited into this pit for many decades?
We passed this question on to TVA and received the following response:
A: The Allen Fossil Plant is a different type of plant from the Kingston Plant and thus produces a different type of coal waste by-product.
The wastes from the Allen Plant are 80% boiler slag and 20% fly ash. The boiler slag is wet sluiced to the main ash pond and then retrieved and 100% marketed offsite. The boiler slag is typically used for sand blasting grit and roofing shingles. The fly ash is being wet sluiced to the main ash pond, dewatered, and hauled offsite to be used as industrial fill at the Pidgeon Industrial Park.
One hundred percent of the fly ash is being utilized as structural fill.
The ash pond at Allen is used as a temporary storage facility prior to shipping coal waste by-products off site.
