Veolia Contacts Bart Haynes Kevin Zenkevich | Situation Overview Following a devastating coal ash pond spill 2008 at the Tennessee Valley Authority (TVA) Plant in Kingston, Tenn., the coal power industry changed forever. Shortly after midnight on December 22, 2008, in a time span of 50 minutes, five million cubic yards (1.1 billion gallons) of wet coal ash broke from its storage pond creating the largest spill of its kind in U.S. history. The three-year recovery is expected to cost between $1.0B and $3.0B to clean up. The short-term result is that TVA is converting 100% of its wet ash handling storage and disposal systems (at 11 plants) into dry handling and storage systems over the next 10 years at a capital cost expected to exceed $2.0 billion. Coal ash storage ponds throughout the industry are at 80% capacity and 130 million tons of new ash is being generated each year, most of which is wet ash that carries the greatest risk for coal power plants. The long-term result of the TVA disaster is that the entire coal power industry is now developing strategies to convert from wet ash systems to dry ash systems. In February 2009,Veolia ES Industrial Services’ Separations and Tank Cleaning Division in Ashland, Ky., was contacted by a coal power company located in southern Ohio. Motivated by the December 2008 disaster in Tennessee and fearing that they faced similar risks, this company was very motivated to work with Veolia to seek both short- and long-term solutions for ash management.
