So right, RKY! I think that the "engineering" required here is a matter of evaluation of the dry stack site and its ability to support the proposed weight.
We have to remember that this is a mining area and there very well may be old, uncharted mine shafts, voids or sinkholes under the area.
Now is the time to make sure that CGFIA is "doing it right" so they don't run into future liability due to poor planning or a rush to production.
I can wait. I know these things take time. This is a perfect example of "measure twice, cut once"!
