Pebble has 90 days to reply with a plan to mitigate the damage. The Army Corps said in a statement that the project "as currently proposed, cannot be permitted" under the Clean Water Act. The Army Corps cited a federal code that requires Pebble to restore, enhance or preserve an area comparable to that which would be damaged by the mine. Pebble CEO Tom Collier dismissed the significance of the letter, telling CNN it was a routine notice that didn't impede the progress of the project. Collier added that the effort has been ongoing for more than three weeks.
