Not sure what you saw, but the timeframe for an APP on a hardrock mine is definitely not months. They will have to characterize the tailings and dump material, along with potential ore they hope to pull from the mine, and also the water in the mine. They will have to do a hydrogeological study, and probably put in monitoring wells. They will have to prepare an engineered plan and drawings for the lined tailings pond and waste dumps, and they need a Storm Water Plan.
It will be a lot of back and forth between the mine operators and ADEQ, and there are always multiple revisions to every application. If they can do all this in "months", it would be a new record for a hard rock mine in Arizona. Most mining APPs take several years, and I know of at least one that has dragged on for over 10 years.
And, by the way, they will need a real engineer to sign off on this stuff, not a "SME Registered Mining Engineer".
An APP is not just a "plan and paperwork".
