The National Journal reported that the United States Environmental Protection Agency won’t allow a large copper and gold mine to be built near Alaska’s Bristol Bay. The Pebble Partnership, who wants to develop the mine and is 100 percent owned by Northern Dynasty Minerals (TSX:NDM) spoke against action taken by the EPA through its draft Clean Water Act on Friday, according to the publication. The developers have yet to submit their formal application and development plan.

As quoted in the publication:

The agency, in a proposed Clean Water Act finding, said large-scale mining of what’s known as the Pebble deposit could “result in significant and unacceptable adverse effects on ecologically important streams, wetlands, lakes, and ponds, and the fishery areas they support.” Bristol Bay is home to the world’s largest sockeye salmon run.”The science is clear that mining the Pebble deposit would cause irreversible damage to one of the world’s last intact salmon ecosystems,” said Dennis McLerran, who heads EPA’s Alaskan and Pacific Northwest operations, in a statement.
