Misleading people is much cheaper than environmental stewardship:
In response to your Aug. 18 editorial ("Why not recycle coal ash instead of burying it?"), we at Duke Energy agree that as much coal ash as possible should be recycled. State policy leaders also strongly support the option and outlined provisions in the N.C. Coal Ash Management Act to encourage recycling.
The structural fill projects at the mines in Lee and Chatham counties, for example, are a form of beneficial reuse for the ash stored in basins. By reclaiming those sites and safely placing coal ash in them with many layers of protective liners, we will help repurpose land that can be reused for future development.
Bolding mine. There is only going to be one "liner" in the classic sense of a man-made polymer, the rest are a couple of layers of various composites of clay. Calling those "liners" is like calling the leaves over your head a roof. And that single polymer liner won't be a continuous (as in unbroken) liner, it will be several pieces that need to be connected and sealed, hopefully properly. But even if that liner doesn't leak, the nasty leachate water from the coal ash isn't going to stay in the impoundment, it's going to be pumped out on a regular basis and disposed of:
