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.
