EPA’s Pebble ‘veto’ won’t stop all mining in Alaska’s Bristol Bay

May 31, 2022 — EPA’s move to ban mining the Pebble deposit in the Bristol Bay watershed this week set off a swirl of questions about whether the proposed Clean Water Act veto could have broader implications for mining in one of the world’s premier salmon habitats.

But a close look at the agency documents explaining the decision makes it crystal clear: The Pebble veto won’t stop mining in Bristol Bay, much less the rest of the Last Frontier.

EPA’s proposed veto Wednesday only targets efforts to mine the Pebble deposit. It was based on a mine plan Pebble LP and its backer Northern Dynasty Minerals Ltd. submitted to the Army Corps of Engineers as part of the Clean Water Act permitting process two years ago.

That mine plan specifically affected three watersheds, the South and North Forks of the Koktuli River and the Upper Talarik Creek, where it would permanently damage 99 miles of stream habitat and more than 2,000 acres of wetlands. EPA says it is vetoing the project because it would result in four “unacceptable adverse effects” on aquatic life and habitat, including the loss of salmon habitat and negative effects on the genetic diversity of salmon in the watersheds.

The veto is limited to certain headwaters of those watersheds, and includes approximately 309 square miles surrounding the 2020 mine plan. There are other mine claims within that restricted area, however the veto documents are clear that the restriction only applies to mining the Pebble deposit, specifically.

A Rare Salmon Type Is in the Crosshairs of Alaska’s Proposed Pebble Mine

August 31, 2020 — The sockeye salmon that come from the Koktuli River aren’t like most other fish in Alaska’s Bristol Bay, where a thriving fishery provides nearly half of the world’s wild sockeye. These salmon represent a rare class of sockeye with unique genes and a singular life strategy that sets them apart from the millions of fish that spawn in the rivers and streams that feed into Bristol Bay. Now, Koktuli River sockeye are in the spotlight because the Pebble Mine, a copper and gold mine proposed for southwest Alaska, is slated for the water in which they live.

On Monday, August 24, the latest development arrived in the long and controversial story of the Pebble Mine. The US Army Corps of Engineers (USACE), the agency in charge of permitting the mine, posted a letter officially informing the project’s developer, Pebble Limited Partnership (PLP), that the open-pit mine, as proposed, would “cause unavoidable adverse impacts” to the surrounding watershed, resulting in “significant degradation.”

That determination would be a death knell for the project per the Clean Water Act—unless the company takes appropriate steps to mitigate or offset the damage it will cause to more than 1,300 hectares of wetlands and nearly 300 kilometers of streams, most of which lie within the Koktuli River watershed. In recent weeks, prominent Republicans, including President Trump’s oldest son, Donald Trump Jr., and Fox News commentator Tucker Carlson, have voiced opposition to the mine, feeding speculation ahead of Monday’s letter that the administration might block or delay the project.

ALASKA: Why biologists fear Pebble could risk Bristol Bay salmon’s resilience

August 3, 2020 — The U.S. Army Corps of Engineers’ final environmental review of Pebble says that under normal operations, it does not expect the mine to have a significant effect on fish populations in Bristol Bay. But the Corps does say the mine would harm fish around the mine site. Some scientists say the project could also put a specific salmon population in the Koktuli River at risk and remove genetic diversity from the region.

The mine would be built at the headwaters of the Koktuli River drainage, and it would eliminate about 20% of available habitat there, though the Corps says that does not necessarily represent fish habitat.

Daniel Schindler has spent decades studying salmon in the Bristol Bay watershed. He’s a professor of fisheries sciences at the University of Washington

“If you looked at the Koktuli all by itself, and you assumed that all sockeye salmon are interchangeable across all of Bristol Bay, then you would say that the Koktuli River is a very small piece of habitat, and it’s not that important,” he said.

According to Schindler, the variety of different life strategies and genetic identities of sockeye throughout Bristol Bay ultimately stabilizes the returns of fish back to the rivers every year.
