John Boyle, commissioner of the Alaska Department of Natural Resources, abruptly resigned his position on Friday.
Gov. Mike Dunleavy announced the appointment of his deputy, John Crowther, as acting head of the agency that regulates Alaska’s agriculture, mining, oil and gas.
The governor’s office declined Monday to answer questions about the resignation, which had not been previously announced.
Dunleavy is term-limited and will leave office in December 2026. Boyle’s departure follows those of Revenue Commissioner Adam Crum and Attorney General Treg Taylor.
The resignations of both of those men — who are now Republican candidates for governor in next year’s elections — were announced in advance, unlike Boyle’s departure.
Boyle could not be reached for comment on Monday.
The departing commissioner has extensive experience in the oil industry. Before joining Dunleavy’s cabinet in 2023, he was a lobbyist for BP and Oil Search.
Crowther, who will replace Boyle on an interim basis, has been with the Department of Natural Resources since 2012, the governor’s office said.
He previously worked as director of the governor’s Washington, D.C. office and served on the staff of the U.S. Senate’s Energy and Natural Resources Committee. He holds a law degree from Georgetown University.
“The Department of Natural Resources is at the forefront of protecting and developing Alaska’s precious land and waters. Mr. Crowther’s legal background and experience as a deputy commissioner make him a great choice to advance the responsible development, and maximum use, of Alaska’s natural resources consistent with the public interest as mandated by Alaska’s Constitution,” the governor said in a prepared statement released on Friday.
