Sen. Lisa Murkowski, R-Alaska, might use her prerogative to block consideration of President Obama's nomination of Sally Jewell to lead the Department of Interior.
According to a report in the Anchorage Daily News, Murkowski is considering the move as a way to force the administration to agree a land exchange permitting construction of a road between Cold Bay and King Cove.
The contemplated road would cross the Izembek National Wildlife Refuge in southwestern Alaska, which provides habitat for a variety of species including grizzly bears, moose, caribou, and five species of Pacific salmon.
Of the 315,000 acres in the Izembek National Wildlife Refuge, 300,000 are included in the National Wilderness Preservation System.
In exchange for the land needed to build the single-lane, gravel road across 206 acres of the refuge, the state of Alaska and native American tribes would trade about 56,000 acres of land to be added to the refuge.
The U.S. Fish and Wildlife Service rejected the proposed land exchange on Feb. 5.
Current interior secretary Ken Salazar will visit residents in the region that would benefit from the road during a trip to Alaska scheduled for next week.
