Stahl every year, coal burning power plants generate not only electricity, but a Staggering Amount of leftover coal ash that contains heavy metals unhealthy to humans. Yet, due in part to intense industry lobbying, there are no federal regulations on its disposal. Its left to the states to oversee some of the most powerful Utility Companies in the country. So coal ash is often just dumped into giant pits that are dug by rivers and lakes, where toxins can leach into nearby water and soil. There are over 1,000 ash pits or ponds dotting the nation, many of them old, poorly monitored, all but forgotten. But every few years, we are reminded that the status quo can lead to disaster, like the coal ash spill this past february into North Carolinas dan river at a power plant owned by duke energy, the biggest Utility Company in the country. The spill at dan river happened when a Drainage Pipe that ran underneath an ash basin and dam collapsed, sucking out six decades of waste and spewing gunk directly into the river. Lynn good it was an accident. It didnt work the way it should have worked. It did not meet our standards or our expectations. Stahl duke energy c. E. O. Lynn good, then only seven months on the job, had a crisis on her hands. How many tons of ash, do you know, went into the river . Good yes, we released between 30,000 and 39,000 tons of ash into the river. Stahl wow. Good we moved immediately to repair the pipe and also begin cleaning the river. And weve used this as an opportunity at duke to raise our standards even higher, of all of our basins to insure and confirm that they were operating safely. Stahl once the water spilled out of the basin, this is what was exposed canyons and ridges of industrial waste the size of 20 football fields, buried right by the river where people fish and swim and get their Drinking Water. But the accident at dan river wasnt the first time a coal ash pond collapsed. It happened to another company six years ago in kingston, tennessee. That spill was more than 100 times larger, smothering homes in toxic muck and choking up the river. After kingston in 2008, did duke raise its vigilance . Did you heighten. . Good yes. There were inspections that went on throughout the industry, certainly at duke, where all the basins were reviewed. Stahl actually, inspections had been going on for years, including this one in 1986 that duke itself paid for. It recommended quantitative monitoring of the very pipe that collapsed, saying it was expected to have less longevity. So that first report urging duke to watch that pipe was 30 years ago. But there were others 1996, 2001, 2006 advising you to keep watching that pipe, over and over. 2009, the e. P. A. Warned about the pipe. Good most of those. Stahl how could you neglect those . Good the results of those inspections indicated that we should monitor, and we were monitoring. And what we were looking for is that the pipe would leak before it failed. But it didnt fail in that way; it failed without leaking. Pat mccrory i dont think duke even knew what was underneath some of their dams and knew the structural issues. Stahl the spill infuriated pat mccrory, the probusiness republican governor of North Carolina. He knows duke well, having worked there for 29 years. How would you describe or rate dukes record on dealing with coal ash disposal . Mccrory well, actually, there has been no record regarding coal ash disposal. Stahl they havent done anything . Mccrory very little, very little. I think the records been quite poor. Because frankly, its been out of sight, out of mind. Good lesley, we have been generating electricity in this country from coal for decades. Stahl and that means coal ash. Good and that ash that has been produced has been stored in accordance with industry standards and practices for decades. Were at a period when the electric system and certainly dukes system is modernizing. Were adding natural gas, were adding renewables, and were closing some coal plants. Stahl fact is, duke closed the dan river plant in 2012, and that perplexed the governor. Mccrory when i heard about the dan river plant having a coal ash spill, my first reaction was, wait a minute. That plants been closed for years. Why are we having a spill at a plant thats not even open . Stahl thats because when they closed the plant, duke just left the ash pond where it was. In an unprecedented program, duke has closed half their coal ash plants in North Carolina in the last three years, blowing up one. After another. After another, as the company switches to natural gas. In all cases, they just left the coal ash ponds and basins behind. Frank holleman this is no way to store industrial waste in large quantities in such a primitive way. Stahl Frank Holleman, an attorney at the Southern Environmental law center, says it makes no sense to store coal ash, that usually contains toxins like arsenic, mercury, thallium, and cadmium, in basins right next to waterways. Holleman it doesnt take a Rocket Scientist to figure out, if you dig an earthen, unlined hole in the earth next to a river, and you put in it a substance that has toxic substances, that is going to leak into the groundwater. It doesnt take a genius to figure that out. Stahl your organization, you have been suing duke energy. Holleman thats correct. Well, what we have hoped is that we could convince duke to get the coal ash out of these unlined pits, move it to safe, lined, dry storage away from the waterway. Stahl thats what duke is already doing with most of its newly generated ash, trucking it to dry, lined landfills away from waterways, or sending it off for reuse as building material. But the companys big problem is what to do with the 100 million tons of old coal ash its accumulated in their 32 ponds in North Carolina some, like this one, up against peoples backyards where children play. Good lesley, were committing to closing all of the sites. Stahl when you say close, what do you mean by close . Good so, there are various methods that can be used to close. Certainly, excavating them to a lined landfill is one of the methods. Stahl that method would cost up to 8 billion. But duke is considering two other options lining the bottom and top of the ponds, but leaving the ash there, which would cost somewhat less, or least pricy at 2 billion cap in place, which means just covering the top of the pond. With no lining on the bottom . Good and typically, cap in place is not lined on the bottom. But we would not move forward with a cap in place unless we had a certainty that the water is safe. And so, thats where the science comes in. Thats where the study needs to be completed, so that we develop smart solutions. Stahl its called cap in place. Holleman cap in place. Stahl right. Now, would that satisfy your organization . Holleman no, it would not. An unlined pit next to a river, a lake, or a Drinking Water reservoir it stays wet. Only if you have a lining in it do you separate this industrial waste from the water table and the groundwater, so cap in place is only pollute in place. Stahl obviously, im not a scientist, but shouldnt you just say, okay, were going to line them all . Good id love to tell you there is a simple solution to this. Id love to tell you that ash. Stahl well, why isnt that a simple solution . Good . That ash that has been stored for decades can be solved quickly. We like quick answers. We like to pull our cell phone up and do research and get answers right away. But in order to do this right, we do need to do the study. We need to understand, what is the groundwater . Where is the groundwater . We need to understand the stability of the basin. We need to understand the soil type. I cannot immediately move 100 million tons of ash. Its not a response that makes any sense, doesnt make common sense. As much as id love to tell you theres a simple solution, its one that requires study, and its one that requires time to complete. Stahl but environmentalists say studying is code for stalling, because this problem isnt new. Duke has been conducting tests around their ash ponds for decades. And five years ago, when state regulators demanded to see the data, they found something alarming the coal ash ponds in all of dukes 14 plants were either leaking toxic chemicals into rivers and streams, or contaminating the groundwater. Good some of the readings that we have found are for elements like iron and manganese, which are naturally occurring. Stahl but nine of your plants have been found to have groundwater violations for contaminants including lead, sulfate, boron, chromium, thallium, selenium, and arsenic. Good so we have had exceedances. And when i said iron and manganese, lesley, i was talking about the majority of them. We have had instances of other readings, as well. Stahl well, im citing your own monitoring statistics, which do say that there have been hazardous chemicals that have entered the groundwater or surface water at all 14 plants, by your own admission. Good and what we have recommended, and will be moving forward with, and the state has recommended, is further assessments so that appropriate steps can be taken. Stahl laughs good so, lesley, i think. Stahl further assessments good i know, i think its important to understand this, and i. Stahl but even you have to throw your head back and say, further assessments . but these results go back years. And to say we need to study more, you know, is a very frustrating thing to have to hear, and im not even a citizen of North Carolina. Good we have very openly and transparently disclosed these results to work with the regulators to determine whether it really represents a risk. Stahl does dukes coal ash today pose any health risk at all . Good i believe our system is operating safely. Stahl but local environmentalists showed us leaks from several of dukes ash ponds, like this one at cape fear. This stream is like this, leaking coal ash into the river 24 hours a day, 365 days a year. Stahl after we asked state officials about this particular leak, lab tests were done showing notably elevated concentrations of sulfate, aluminum, iron, manganese, boron, and strontium. The state says the leak doesnt impact the Overall Health of the river, but is illegal, a violation of the clean water act. Yet environmentalists like Frank Holleman say that, over the years, the state never forced duke to clean up its ash ponds, under both democratic and republican administrations. How powerful is duke energy in the state of North Carolina . Holleman its the most powerful entity in the state of North Carolina. It spends millions of dollars on political contributions, and it has traditionally had a very close relationship with the state regulators. Stahl just this year, governor mccrory cut the budget and staff of the specific department that inspects the ash ponds. The state legislature did pass a law in august requiring duke to clean up its plants, but only after the company had already volunteered to do that. Earlier, when holleman tried to sue duke, he was thwarted by the state, which stepped in and negotiated a settlement that allowed duke you guessed it more time to study, and imposed only a paltry fine. Tell everybody how much the fine was. Mccrory i dont have that list, but again. Stahl it was 99,111. Mccrory thats correct. Stahl which does not sound like a big fine. Mccrory it wasnt a big fine. Stahl all this has made federal prosecutors suspicious. They empanelled a grand jury to investigate whether duke or the regulators has done anything illegal to get the state to go easy on the company. Virtually every newspaper in the state of North Carolina came out with editorials claiming that duke was lax, and lawless, when it came to the environment, and acted like a bully with state regulators. Good i recognize that. I disagree with that characterization. Theres been. Its been a challenging time, a difficult time. Lots of voices weighing in. Certainly lots of scrutiny and criticism. Stahl but you must take this to heart, if theres so much of it, you know . Good of course we do. We take this very seriously. And were using this as an opportunity to raise our standards even higher, to ensure that our operations are safe. Its our highest priority at duke. Stahl later this month, the Environmental Protection agency is set to announce whether coal ash will be regulated by the federal government as hazardous waste, meaning potentially much tougher disposal rules and waste, meaning potentially much tougher disposal rules and oversight.
