Urge the EPA Administrator McCarthy: Protect Bristol Bay!

The Science is Clear: It's time to put an end to the Pebble Mine!

Alaska’s Bristol Bay: the world’s greatest wild salmon fishery
Year after year, millions of wild salmon return to Bristol Bay like no other place on earth. It provides 14,000 jobs for hard-working fishermen, sustains the Alaska Native people, and provides food for Alaska’s bears, beluga whales, and other wildlife.

The proposed Pebble Mine
In the heart of Alaska Bristol Bay, a Canadian company, Northern Dynasty, wants to build the Pebble gold and copper mine, which would be the largest open pit mine in North America - generating up to 10 billion tons of toxic mine waste and destroying salmon streams.

The science is clear
A scientific study by the Environmental Protection Agency (EPA) demonstrates that mining the Pebble deposit would have severe and lasting impacts to Bristol Bay salmon.

Urge the EPA: Protect Bristol Bay!
The EPA has the authority under 404c of the Clean Water Act to prohibit the disposal of mine waste in the pristine waters of the Bristol Bay watershed to protect the fishery. The science is clear. It’s time to stop studying, and take action.

TAKE ACTION: Urge the EPA and President Obama to ACT NOW to protect the world’s greatest wild salmon fishery.
