Coal Ash Spills

Papers
  1. Duke Energy's Coal Ash Spill in North Carolina (LATimes.com)
      "Federal prosecutors have broadened their criminal investigation of state environmental regulators after a massive coal ash spill Feb. 2 that contaminated the Dan River in North Carolina, issuing 20 more subpoenas demanding documents about communications and possible payments and gifts."

      "The subpoenas, disclosed Wednesday, require the state Department of Environment and Natural Resources to produce records of any payments or 'items of value' received from or provided to Duke Energy, the giant utility whose coal ash containment basin spilled as much as 82,000 tons of toxic coal and 27 million gallons of contaminated water into the river." 02-14

  2. Kingston Coal Ash Spill (Wikipedia.org)
      "The TVA Kingston Fossil Plant coal fly ash slurry spill occurred just before 1 a.m. on Monday December 22, 2008, when an ash dike ruptured at an 84-acre (0.34 km2) solid waste containment area at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, USA. 1.1 billion US gallons (4,200,000 m3) of coal fly ash slurry was released. 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 wet form in dredge cells. The slurry (a mixture of fly ash and water) traveled across the Emory River and its Swan Pond embayment, on to the opposite shore, covering up to 300 acres (1.2 km2) of the surrounding land, damaging homes and flowing up and down stream in nearby waterways such as the Emory River and Clinch River (tributaries of the Tennessee River). It was the largest fly ash release in United States history." 02-14

  3. What Needs to Be Done With Coal Ash Waste? (LATimes.com)
      "What is the largest type of trash produced in the U.S.? Itís not whatever youíre thinking, most likely. Itís coal ash."

      "Burning coal produces more than 100 million metric tons of coal ash per yearóthe gray or black sooty aftermath of our fossil fuel habit. Even though a good chunk of it is turned into concrete, tens of millions of metric tons end up dumped back into old mines and landfills or impounded in slurry ponds (to keep it from blowing away)."

      "Coal ash is not a benign form of garbage. Burning coal concentrates the heavy metals and other toxic elements (including radionuclides) found in the dirtiest of fossil fuels. Samples of Dan River water sent for testing by Waterkeeper Alliance revealed arsenic, chromium and lead at dangerously high levels. The arsenic levels of 0.349 milligrams per liter is some 35 times higher than levels considered acceptable for drinking water by the U.S. Environmental Protection Agency (EPA)."

      "The EPA is still considering the larger question of what should be done nationwide about this toxic pollution that we have in copious quantities, after industry criticism stalled the first-ever proposal in 2010 to regulate the hazardous waste. But the agency has already determined that more than 580 coal-ash storage sites exist in varying states of repair across the U.S., many like the one that leaked into the Dan River." 02-14
