U.S. Secretary of the Interior Ryan Zinke has announced a long-awaited development for oil and gas energy production offshore the state of Alaska. Interior’s Bureau of Ocean Energy Management (BOEM) issued conditional approval to Hilcorp Alaska LLC for its Liberty Project oil and gas development and production plan. If developed, the facility would be the first oil and gas production facility in federal waters off Alaska.

Hilcorp proposes to build a nine-acre artificial gravel island in the shallow waters of the Beaufort Sea, about 20 miles east of Prudhoe Bay and about five miles off the coast. The facility would be similar to the four oil-and-gas-producing artificial islands currently operating in the area’s state waters: Spy Island, Northstar Island, Endicott Island and Oooguruk Island.

"Working with Alaska Native stakeholders, the Department of Interior is following through on President Trump’s promise of American Energy Dominance. Today we’re announcing approval of the Hilcorp Liberty Project, which if completed, will be the first production facility ever located in federal waters off Alaska,” said Secretary Zinke. “American energy dominance is good for the economy, the environment, and our national security. Responsibly developing our resources, in Alaska especially, will allow us to use our energy diplomatically to aid our allies and check our adversaries. That makes America stronger and more influential around the globe.”

BOEM used a rigorous evaluation process based on the best and most recent science available to evaluate the safety and environmental impacts of the Liberty Project. The plan was conditionally approved only after incorporating input from the public, and from North Slope communities and tribal organizations. As the project moves forward, BOEM will continue to work with Hilcorp to ensure all appropriate safeguards are stringently applied.

Approval conditions include: restricted drilling into the hydrocarbon-bearing zone, which may occur only during times of solid ice conditions; seasonal restrictions on activities and vessel traffic to reduce potential disturbance to Cross Island subsistence whaling activities; and obtaining all required permits from other state and federal agencies.

“There are already four other gravel-island facilities off the North Slope, and we consider Hilcorp’s plan to represent a relatively conservative, time-tested approach toward offshore oil and gas development," said Joe Balash, the Department of the Interior’s Assistant Secretary for Land and Minerals Management. "Using input from North Slope communities, tribal organizations, and the public, we have developed a robust set of environmental mitigation measures and safety practices that will be applied to this project.”

In August, BOEM published an Environmental Impact Statement that examined the potential environmental impacts of Hilcorp’s proposal, and looked at a range of alternatives. Today’s announcement follows publication of the Record of Decision issued by the Department of the Interior. The Record of Decision, BOEM’s letter of approval and related documents can be found here. A Notice of Availability relating to the Record of Decision will appear in the Federal Register’s Reading Room Thursday, Oct. 25, and in the Federal Register on Friday, Oct. 26.

About the Liberty Project

The Liberty Prospect is located 8.85 km offshore in about 6m of water, inside the Beaufort Sea's barrier islands. It is 32 km east of Prudhoe Bay and about 13 km east of the existing BP-operated Endicott oil field.

In November 2014, primary ownership and operatorship of Liberty was acquired by Hilcorp. Hilcorp estimates that the Liberty Unit contains approximately 150 million barrels of recoverable, high-quality crude oil.
