WASHINGTON — Environmental Protection Agency Administrator Scott Pruitt announced late Friday that he will not scrap the agency’s 2014 determination that a large-scale mining operation could irreparably harm Alaska’s Bristol Bay watershed.
His decision, which falls short of blocking a proposed gold and copper mine in the region outright, represents a surprising twist in a yearslong battle that has pitted a Canadian-owned mining company against commercial fishing operators, native Alaskans and conservationists determined to protect the world’s largest sockeye salmon fishery.
Last spring, shortly after meeting with the top executive from the main company backing the project, Northern Dynasty Minerals, Pruitt directed EPA staff to revisit the Obama-era decision to short-circuit the project using a provision of the Clean Water Act. The 2014 decision came after several years of scientific study during which the EPA determined that the mining operation could cause “significant and irreversible harm” to the area’s fish habitat.
On Friday, after receiving more than a million public comments and consulting with tribal governments and others, the EPA said it will leave the previous administration’s determination in place while it takes additional comments. The announcement said the decision “neither deters nor derails the application process” for the mine.
“It is my judgment at this time that any mining projects in the region likely pose a risk to the abundant natural resources that exist there,” Pruitt said in a statement. “Until we know the full extent of that risk, those natural resources and world-class fisheries deserve the utmost protection.”
An entity known as Pebble Limited Partnership has eyed the spot in southwestern Alaska, where the headwaters of several rivers converge, as a possible mine site for more than 15 years. But Northern Dynasty Minerals, the company leading the effort, didn’t file its first formal application for a federal permit until December.
The EPA’s announcement Friday noted that it “stands ready” to work with the mining company and the Army Corps of Engineers in reviewing the permitting application for the project.
Pebble Limited Partnership and its supporters, including Alaskan politicians such as Sen. Lisa Murkowski, R-Alaska, had criticized the Obama administration for issuing what amounted to a preemptive veto of the project. They argued that tapping the mineral reserves buried underneath the tundra will generate good-paying jobs for local residents and additional revenue for the state and federal government.
But opponents of the mine countered that any spill could imperil one of the world’s great fisheries, which accounts for roughly a fourth of the global supply of sockeye salmon.
Southwestern Alaska contains a reservoir of gold worth an estimated $120 billion, but the lakes and tributaries in the region feed into Bristol Bay and a fishery that generates $500 million a year.
Representatives for Northern Dynasty Minerals did not respond to a request for comment.
