text: I don't love the current condition of the area but it's hard to edit in iD and wonder if it'd be easier for someone familiar with JOSM:
  - landuse=quarry is only applicable to the area where something is currently being mined, but no mining is occurring  here
  - landuse=quarry is currently applied to man_made=spoil_heap and man_made=tailings_pond and shouldn't be
  - landuse=industrial could be applied to the whole area encompassing the spoil heap, tailings pond, and processing plant
  - landuse=brownfield isn't particularly because it assumes a formerly developed area, which it wasn't; it's in the same state it was when the former operator went bankrupt
