JUNEAU — The U.S. Environmental Protection Agency announced Wednesday it is extending through May a timeline to decide how or whether to proceed with proposed restrictions on mining in Alaska’s Bristol Bay region, which is known for its salmon runs.

Acting Regional Administrator Michelle L. Pirzadeh, in a written notice, said an extension through May would allow time “to consider available information in order to determine appropriate next steps, which may include revising” restrictions that were proposed but never finalized under the Obama administration.

The EPA, as part of a 2017 settlement with the developer of the proposed Pebble Mine, agreed to initiate a process to suggest withdrawing the proposed restrictions. The developer, the Pebble Limited Partnership, cast the proposed restrictions as an attempt to preemptively veto the copper and gold mine and said it wanted the project vetted through the permitting process.

The company subsequently filed a permit application with the U.S. Army Corps of Engineers.

In 2019, during the Trump administration, the EPA withdrew the proposed restrictions, removing what it called an “outdated, preemptive proposed veto of the Pebble Mine.”

That action was challenged in court, and the EPA earlier this year asked a judge to vacate the withdrawal decision and send the matter back to the agency for further consideration. The request was granted.

The EPA said the ruling reinstated restrictions proposed in 2014 and triggered regulatory deadlines to either withdraw the proposed restrictions or prepare a so-called recommended determination that would seek to prohibit or restrict activities in an area. The EPA said it can extend the deadline through a notice in the Federal Register and has chosen to do so. The new deadline is May 31.

The corps last year rejected a key permit for the project following an environmental review from the corps months earlier that the Pebble partnership had viewed as a favorable to the project. The Pebble partnership is appealing the rejection.

The Pebble partnership on Wednesday cited the corps’ environmental review and said the EPA “did not have this significant volume of detailed technical information” when it took action previously. The company also said the nation will need minerals the Pebble project could provide.

Nelli Williams, Alaska director of Trout Unlimited, said the timeline laid out Wednesday shows a “strong commitment” by the EPA “to follow through and finish the work started in 2014” to provide protections for the Bristol Bay region.
