Let us start with the legal arguments. The applicable regulations specify that only the party denied a Clean Water Act Section 404 permit can file an administrative appeal of that decision. Corps of Engineers guidance on the appeal process is equally specific, the process “provides permit applicants with an opportunity to seek a timely and objective reconsideration of an adverse permit decision,” and “there is no third-party involvement in the appeal process itself.” This is black and white. Moreover, the Pebble Limited Partnership (PLP), the permit applicant, has already filed an appeal. At best, the state’s appeal is duplicative. At worst, it is an unlawful and wasteful action.

Second, the Corps’ permit denial is based on science and grounded in longstanding precedent. Pebble, even under the conservative 20-year mining plan that PLP itself acknowledges will expand considerably, would impact nearly 200 miles of streams and more than 4,500 acres of wetlands – with no plan to replace these significant losses. These streams and wetlands are part of the unique ecosystem that allows 50 million-plus sockeye salmon to return annually, supporting $1.5 billion in economic output and a millennia-old Alaska Native way of life. The Corps’ finding that the mine would cause significant damage to aquatic resources and is not in the public interest is wholly consistent with extensive scientific data and evidence.
