Alaska gold, copper mine blocked over environmental worries
JUNEAU, Alaska — The U.S. Environmental Protection Agency took an unusually strong step Tuesday and blocked a proposed mine heralded by backers as the most significant undeveloped copper and gold resource in the world because of concerns about its environmental impact on a rich Alaska aquatic ecosystem that supports the world’s largest sockeye salmon fishery.
The move, cheered by Alaska Native tribes and environmentalists and condemned by some state officials and mining interests, deals a heavy blow to the proposed Pebble Mine. The intended site is in a remote area of southwest Alaska’s Bristol Bay region, about 200 miles (322 kilometers) southwest of Anchorage.

The mine site is accessible only by helicopter and snowmobile in winter, developer Pebble Limited Partnership said in a permit application with the U.S. Army Corps of Engineers. As proposed, the project called for a mining rate of up to 73 million tons a year.
An appeal by the Pebble partnership of a separate rejection of a key federal permit is unresolved.
In a statement, Pebble Limited Partnership CEO John Shively called the EPA’s action “unlawful” and political and said litigation was likely. Shively has cast the project as key to the Biden administration’s push to reach green energy goals and make the U.S. less dependent on foreign nations for such minerals.
The Pebble Limited Partnership is owned Canada-based Northern Dynasty Minerals Ltd.
The Pebble deposit is near the headwaters of the Bristol Bay watershed, which supports a bounty of salmon “unrivaled anywhere in North America,” according to the EPA.
Tuesday’s announcement marks only the 14th time in the roughly 50-year history of the federal Clean Water Act that the EPA has flexed its powers to bar or restrict activities over their potential impact on waters, including fisheries.
