US: Georgia Power has started preparation activity to permanently close all of the company's 29 ash ponds located at 11 coal-fired generation facilities across Georgia. Twelve ponds are scheduled for closure by mid-2018, 16 are expected to close by 2026 and one pond is expected to close by 2030. At present, around 50% of the coal combustion by-products Georgia Power produces are used to make Portland cement, concrete, cinder blocks and gypsum wallboard.
"Our primary focus throughout the closure process is maintaining a reliable generation fleet, while conducting the closure process in the most efficient way possible," said Mark Berry, vice president of environmental affairs for Georgia Power. The company will upgrade each plant to accommodate the dry handling of Coal Combustion Residuals (CCR) required by new federal regulations. The closure of all 29 ash ponds is expected to cost over US$1bn over the next 10 years. In addition, the company has invested approximately US$5bn in new environmental compliance technologies for its coal-fired generation fleet.
