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 15,000 jobs, and generates $2.2 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.
In support of the tribal and fishing communities of the region, NRDC has been urging the Biden administration to affirm that the Pebble Mine has no place in Alaska’s Bristol Bay by vetoing the project. A global consensus of support for action by the U.S. Environmental Protection Agency (EPA) from Indigenous communities, the fishing industry, and other businesses 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 destructive scheme.
For millennia, Alaska’s Bristol Bay has sustained us all. It’s an ecological treasure, and it deserves our protection. Lasting protection for Bristol Bay is achievable through an EPA veto in 2022—and we are determined to secure it.

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.
