I have some history with the use of flyash sludge and lime. If mixed correctly it will form a impermeable cap. In fact the Pa Dep actually used this mix to get rid of harbor sludge from NY and NJ. They placed it in a coal strip job where I used to live.1 point

Actually, from an operations standpoint I love those two. The issues there are ecological, but if they are contained properly they are very easy to work, and stable. It's like grading sand; wet it, pack it, and cover it as quickly as possible so that you aren't making dust and rain doesn't erode dirt down to the ash1 point
