July 2002—Cartersville, Ga.: A four-acre sinkhole in an ash pond at Georgia Power's Plant Bowen sends 2.25 million gallons of ash and water into Euharlee Creek, an Etowah River tributary. The state fined Georgia Power $31,250 for the spill. In September 2008, just months before the Kingston spill in Tennessee, another release of ash at the plant occurred due to rainfall, which triggered sloughing of the dry stacked ash, causing it to overflow into the main dike.
