Coeur Alaska's plan to dump mine waste into Slate Lake will set a precedent allowing other mines, in particular the Pebble Mine in the Bristol Bay area, to do the same. Dumping mine tailings into nearby lakes and streams is simply unacceptable. In the 1990s, Coeur had a fully permitted mine with on-land storage of mine tailings before they decided they would rather put the tailings into Slate Lake. If Coeur is planning to use Slate Lake for dumping mine tailings, because it is cheaper than on-land storage, then it should not be mining in this area. If it cannot afford to develop this mine in an environmentally sound way, it should not be permitted to continue.
