When an electrical generating plant burns coal it produces fly ash, consisting of fine particles that "fly" up the smokestack and have to be trapped, and heavier bottom ash. Both of these combustion byproducts are stored in landfills, either together as in the TVA landfill featured in the slideshow and videos below, or separately as in the Westar landfills in Kansas.
As reported by SourceWatch, the coal ash produced by coal-fired plants in the U.S. contains large quantities of toxic metals, including 44 tons of mercury, 4601 tons of arsenic, 970 tons of beryllium, 496 tons of cadmium, 6275 tons of chromium, 6533 tons of nickel, and 1305 tons of selenium. On December 22, 2008 in Kingston, TN a coal plant dike broke releasing 5.4 million cubic yards of sludge containing toxic chemicals including arsnic, cadmium, chromium, lead, mercury spilled into the Emory River. The 40-acre pond, whose dam broke, was used by the Tennesee Valley Authority as a containment area for ash generated by the coal-burning Kingston fossil Plant in Harriman, Tennesse more information. Many homes were destroyed or damaged and the spill contaminated area water wells, the river and destroyed untold aquatic life.
In the slideshow below, Donna Liseby, Upper Watauga Riverkeeper, hands off a sample of coal slurry collected in the Emory River just below the TVA coal ash spill to the Kansas Riverkeeper. Donna was one of the Waterkeepers who took samples in the Emory River on December 27, 2008 and posted a video on YouTube.
In terms of our local situation, the Jeffrey Energy Center is ranked 99th out of the top 100 most polluting power plants for storage of coal combustion byproducts; during 2006 Jeffrey Energy Center released 190,417 pounds into surface impoundments.
