This is what coal ash looks like: Dan River spill

On Feb 3, 2014, Duke Energy said 50,000 to 82,000 tons of coal ash and up to 27 million gallons of water were released from a pond at its retired Dan River Steam Station into the Dan River, and were still flowing. A 48-inch stormwater pipe beneath Duke's unlined ash pond broke, and water and ash from the 27-acre pond drained into the pipe.[2]

According to EcoWatch, the coal ash spill appears to be the third-largest in U.S. history. It was discovered after a security guard noted the coal ash pond was running lower than usual, meaning much of it had already drained into the Dan River. Residents of Danville, VA withdraw drinking water just six miles downstream of the spill site.[3]

Coal waste in the United States

A January 2009 study by The New York Times following the enormous TVA coal ash spill found that there are more than 1,300 surface impoundments across the U.S. containing coal waste, with some sites as large as 1,500 acres.[4] Also in January 2009, an Associated Press study found that 156 coal-fired power plants store ash in surface ponds similar to the one that ruptured at Kingston Fossil Plant. The states with the most storage in coal ash in ponds are Indiana, Ohio, Kentucky, Georgia and Alabama. The AP's analysis found that in 2005, 721 power plants generating at least 100 MW of electricity produced 95.8 million tons of coal ash, about 20 percent of which - or almost 20 million tons - ended up in surface ponds. The rest of the ash winds up in landfills or is sold for other uses.[5] In June 2009, EPA released its list of 44 "high hazard potential" coal waste sites, which included 12 sites in North Carolina, 9 in Arizona, 6 in Kentucky, 6 in Ohio, and 4 in West Virginia.[6] The full list is available here.

"High Hazard" Surface Impoundments

Two of Dan River Steam Station's coal ash surface impoundments are on the EPA's official June 2009 list of Coal Combustion Residue (CCR) Surface Impoundments with High Hazard Potential Ratings. The rating applies to sites at which a dam failure would most likely cause loss of human life, but does not assess of the likelihood of such an event.[7]

Coal Ash Waste and Water Contamination

In August 2010 a study released by the Environmental Integrity Project, the Sierra Club and Earthjustice reported that North Carolina, along with 34 states, had significant groundwater contamination from coal ash that is not currently regulated by the Environmental Protection Agency (EPA). The report, in an attempt to pressure the EPA to regulate coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites.[8] The report mentioned North Carolina based Dan River Steam Station as having groundwater contamination due to coal ash waste.[9]

Study finds dangerous level of hexavalent chromium at Dan River coal waste site

A report released by EarthJustice and the Sierra Club in early February 2011 stated that there are many health threats associated with a toxic cancer-causing chemical found in coal ash waste called hexavalent chromium. The report specifically cited 29 sites in 17 states where the contamination was found. The information was gathered from existing EPA data on coal ash and included locations in Alabama, Arkansas, Delaware, Florida, Illinois, Indiana, Minnesota, Massachusetts, North Carolina, North Dakota, Nevada, Ohio, Oklahoma, Pennsylvania, Tennessee, Virgina and Wisconsin. In North Carolina, the Dan River Steam Station in Eden, the Asheville Plant in Asheville and the Cape Fear Steam Plant in Montcure all were reported as having high levels of chromium seeping into groundwater.[10]

According to the report, hexavalent chromium (Cr(VI)) was reported at the Dan River unlined landfill and pond coal waste site above 61 ppb (parts per billion) - 3,050 times the proposed California drinking water goals and 22% above the North Carolina drinking water standard.[10]

As a press release about the report read:

Hexavalent chromium first made headlines after Erin Brockovich sued Pacific Gas & Electric because of poisoned drinking water from hexavalent chromium. Now new information indicates that the chemical has readily leaked from coal ash sites across the U.S. This is likely the tip of the iceberg because most coal ash dump sites are not adequately monitored.[11]

According to the report, the electric power industry is the leading source of chromium and chromium compounds released into the environment, representing 24 percent of releases by all industries in 2009.[10]
