Ok, so define that procedure? If I wanted to floor in an entire cell with sludge, there is nothing but common sense stopping me from doing that. What percentage of sludge is too much to maintain a stable working face? How many tons of trash have to be available to mix with X amount of sludge? What do you do when it's raining and the sludge coming in doubles? What do you do when you are sliver filling an outside slope, where you can't put sludge?
The simple answer to all of those questions is to set a limit on how much you can take, but when a government office makes a vague statement about "improper handling" after a fatality, then there is nothing these companies will change. They can just point at Greentree and say "They handled it wrong, won't happen to us".
I'm just so disgusted by all of this, I thought it may bring about change, but it looks like it won't happen
