Stop the Pebble Mine, Save Bristol Bay
What's At Stake
One of the earth’s most pristine ecosystems is being threatened by a proposed open-pit mega-mine.
The Pebble Mine—proposed at the headwaters of the planet’s greatest wild salmon fishery in Bristol Bay, Alaska—threatens the communities and ecosystems that depend on the bay’s abundant wildlife. It’s also a terrible investment, pitting an eternal supply of food against an eternal supply of poison.
The Bristol Bay watershed is one of America’s last great wild places, home to bears, eagles, and wolves. It provides half the world’s wild sockeye salmon, supports 14,000 jobs, and generates $1.5 billion in economic activity every year. But if this gold and copper mine gets built, it will poison the bay’s headwaters with up to 10 billion tons of mining waste that will have to be stored—forever—in a wet and seismically active region. And that risk has grown since former U.S. Environmental Protection Agency chief Scott Pruitt cut a backroom deal with Northern Dynasty Mineral Ltd., the Canadian company behind the toxic Pebble Mine project, throwing a lifeline to company and emboldening it to apply for permits and seek new investors.
NRDC has been calling on the Trump administration to affirm that the Pebble Mine has no place in Alaska’s Bristol Bay and will continue to do so with the Biden administration. Backlash from businesses, fishing communities, and Indigenous groups is growing, and major investors—including Mitsubishi, First Quantum Minerals, Anglo American, and Rio Tinto, some of the world’s largest mining companies—have already abandoned this risky project.
For millennia, Alaska’s Bristol Bay has provided for us. It’s an ecological treasure—and it deserves our protection.

The Army Corps found that the proposed gold and copper mine would cause “unavoidable adverse impacts to aquatic resources” in Alaska’s pristine Bristol Bay watershed that has sustained Indigenous subsistence cultures for thousands of years.
This is an environmental justice issue for our people. If our land and water are devastated, our people are devastated. The Army Corps is not listening . . . [and the company is] dismissive of our people’s concerns.
