We’ve just learned there has been a catastrophic breach in an earthen dam holding back billions of gallons of contaminated water and mining waste at the Mount Polley copper and gold mine in British Columbia. The unleashed waste is now cutting a poisonous path of destruction through pristine forests and is spilling into waterways where salmon spawn.

That mine has chilling similarities to the proposed Pebble Mine, which would be gouged out of Alaska’s spectacular Bristol Bay wilderness — home to the greatest wild sockeye salmon runs on the planet, an astounding diversity of wildlife and Native communities that have thrived there for thousands of years.

Send an emergency message to the EPA telling them to stop the Pebble Mine.

The company responsible for designing the failed Mount Polley dam has also been hired to design the dams at the Pebble Mine!

The Mount Polley disaster is a horrifying glimpse at what could be in store if the EPA fails to follow through with its proposal to block mega-mining in the Bristol Bay wilderness.

NRDC has been ratcheting up pressure on EPA to do the right thing and stop the mine — but we need your help to mobilize a massive public outcry that will compel the agency to protect Bristol Bay forever.
