Funny thing with the consortium that was behind the Pebble Mine was they wouldn't build the mine if they had to sign on the line to be held responsible if anything went wrong over the mines development and lifetime. They wanted guaranteed in writing that they could walk away free and clear at any point with no responsibility to reclaim the land & watershed if there was a massive spill that destroyed the largest salmon watershed in North America. Seemed pretty crazy to me to also.
Actually it's all over, the entire mine is now uneconomical. The lawyers keep kickin it trying to keep her alive to make some more bucks, no joke.
