2014 Dan River coal ash spill

In February 2014, an Eden, North Carolina facility owned by Duke Energy spilled 39.000 tons of coal ash into the Dan River. The company later pled guilty to criminal negligence in their handling of coal ash at Eden and elsewhere and paid substantial fines. The U.S. Environmental Protection Agency has since been responsible for overseeing cleanup of the waste. EPA and Duke Energy signed an administrative order for the site cleanup.

                                               

Coal-seam fire

A coal-seam fire is a natural burning of an outcrop or underground coal seam. Most coal-seam fires exhibit smoldering combustion, particularly underground coal-seam fires, because of limited atmospheric oxygen availability. Coal-seam fire instances on Earth date back several million years. Due to fine thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground coal-seam fires are the most persistent fires on Earth and can burn for thousands of years, like Burning Mountain in Australia. Coal-seam fires can be ignited by self-heating of low-temperature oxidatio ...

                                               

Coal slurry

To transform the coal ash into a slurry, coal is separated from non-combustable components and can be fractionated by particle size as well. Coal slurry can be transferred by pipeline or with specialized pumps such as a progressive cavity pump to pump the highly abrasive, corrosive and viscous coal slurry. More than 7 billion tons of coal are mined per year 2010, using approximately 200 litres of water per ton. However, the amount of water required hinges on the surface characteristics of the coal being used. Most coal slurries require the addition of a surfactant to reduce the viscosity, ...

                                               

Kingston Fossil Plant coal fly ash slurry spill

The Kingston Fossil Plant coal fly ash slurry spill was an environmental and industrial disaster that occurred on Monday December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authoritys Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons of coal fly ash slurry. The coal-fired power plant, located across the Clinch River from the city of Kingston, uses ponds to dewater the fly ash, a byproduct of coal combustion, which is then stored in ponds. The spill released a slurry of fly ash and water, which traveled across the Emory River a ...
