Transcript of Coal Ash Disasters

Failure of main settling pond

Due to excessive precipitation followed by low temperatures

Released 1.1 billion gallons of coal ash into Emory River

101 times the size of Exxon Valdez Spill Coal Power Plants waste as fly ash, bottom ash, boiler slag

Composition depends on coal type

Over 150 trace metals at 10 times concentration of coal

131 million tons annually in US

Profitable secondary market with 43% in 2010 recycled into cement, agriculture, construction materials EPA Assessment
Identified and assessed 431 coal ash impoundments

49 characterized as "high hazard" landfills

Found differences in management

EPA Proposed Changes to Regulations
Differences to regulate under Resource Conservation and Recovery Act

Solid waste in Subtitle D (state)
Hazard waste in Subtitle C (federal)

Review process for regulations and management, rule due in 2012 Technological Disaster:
