Development of Dredged Ash Disposal Area: Johnsonville Fossil Plant: Final Environmental Assessment.

DE89014511

Publication Date	1989
Page Count	65
Abstract	Johnsonville Fossil Plant is located on the east shore of Kentucky Lake and is approximately 12 miles west of Waverly, Tennessee. The plant has 10 coal-fired units with a total generating capacity of 1485 megawatts. The first unit began operation in late 1951 and the tenth unit in 1959. The present coal ash disposal method at Johnsonville is sluicing fly ash and bottom ash to the active ash pond, which is 91 acres in size. This pond requires periodic dredging to maintain compliance with the NPDES permit free water volume requirement. The ash dredged from this pond has been hydraulically conveyed to settling ponds constructed in the rail loop area on the TVA reservation. With the current ash production at Johnsonville averaging 255,000 tons per year, the rail loop will reach maximum storage capacity in 1990. In order to continue future electrical generation at Johnsonville, the development of a new ash disposal area is needed by 1990. This assessment is to evaluate the environmental consequences associated with the development of a new area for dredged ash disposal and an associated small borrow area. 8 refs.
