Yes, some ground is easier to process, but that isn't the limiting factor. But the real cost is the toxic waste created and labor and the ground is super torn up because you process so much. It helps if you can do it far away from people. Hopefully they have a better plan to clean up afterward.
Unfortunately this is also in pretty decent farming land. The land owners will be compensated, but I understand many don't feel too happy about leaving their farms...
