Forget the clean up of stuff you cant see and tear that schitt down. How long did Uniroyal sit polluted ? How many other sites sit polluted ?

Get a demolition company in there while there is still some steel left and that will reduce costs of getting the brick and mortar structure out of there, a responsible company would have probably tore it down free for the hauling if it was complete. Stripped poured concrete structure probably not so much.
I would think most of the face brick is salable and or holding a little value, labor intensive to get but thats low skilled job creation for dead krak headz ?
