Doe Run is the company that owns the smelter in MO that the EPA is forcing to close. However, they own many different operations world wide..........the closest is in Peru, South America. They just restarted that operation in June 2013 after a big cleanup and new filter systems forced on them by Washington putting pressure on the Peruvian Gov...........however, that site was one of the worst polluted smelters in the world at one time......if you believe the tree huggers.
Peru has a Free Trade Agreement with the US........so prices may not go to much higher..........one hopes.
