I've heard of a few of these in the US, but have not heard of any in the UK, where we also burned a lot of coal. Did we manage the ash differently? I have a vague idea that we have a different kind of coal, which produces less ash.
I couldn't find anything conclusive, but found this from 2015:
> Storage, whether in lagoons, silos or landfills, rather than re-use, is the default solution for coal ash management in most countries. The UK’s Department of Environment, Food and Rural Affairs (Defra) estimates that, of the eight million tonnes of coal ash produced in the country each year, half is re-used, while over 300 million tonnes have been stored in lagoons or silos since the 1950s. [...] The American Coal Ash Association (ACAA) reports on US coal ash production and use each year. In 2013, 53 million tonnes of coal ash were generated, of which 23 million tonnes were re-used. Of the unused portion, the EPA says 36 per cent was stored in landfills, and 21 per cent in wet storage facilities. [...] Some countries are doing better, though: for example, the Netherlands recycles 100 per cent of its coal ash because landfill is not allowed in the country. In Germany, where around 10 million tonnes of coal ash are produced per year, around 97 per cent is re-used, with the rest stored only on a temporary basis. According to the European Coal Combustion Products Association (Ecoba), of the 48 million tonnes of coal ash produced in 15 EU countries in 2010 (the latest available figures), 13.8 million tonnes were re-used.

The "re-use" is by processing it into materials which can be used for various construction and materials manufacturing processes. There's lots of other fascinating details about coal ash in there. Wikipedia is pretty good too:
