Description:
The proposed Alaska LNG Project is comprised of the following integrated and interdependent facilities: an LNG terminal in Southcentral Alaska designed to produce up to 20 million metric tons per annum of LNG; an approximately 807-mile, 42-inch diameter gas pipeline; a gas treatment plant (GTP) within the Prudhoe Bay Unit (PBU) on the North Slope; an approximately 1-mile, 60-inch diameter gas transmission line connecting the GTP to the PBU gas production facility; and an approximately 63-mile, 32-inch diameter gas transmission line connecting the GTP to the Point Thomson gas production facility. The mainline of the Alaska LNG Project would traverse over 800 miles from the GTP on the North Slope of Alaska through several boroughs before it crosses Cook Inlet and connects with the liquefaction plant and marine terminal in Nikiski, Alaska.
The project was initially determined to be a FAST-41 covered project in 2017. As represented in the permitting timetable, the federal environmental review and authorization process for the project was originally completed in 2020, and the project was marked as complete on the Permitting Dashboard. After the Department of Energy (DOE) granted a request for rehearing of a final order in 2021, the project was reopened on the Permitting Dashboard to include DOE’s preparation of a supplemental Environmental Impact Statement (EIS). Following the issuance of the supplemental EIS, DOE issued an updated order, and the project was marked as complete on the Permitting Dashboard in 2023.
On February 26, 2025, the project sponsor submitted a notice seeking to reinitiate FAST-41 coverage for updated Biological Opinions (under the Endangered Species Act) and renewed authorizations that are needed for the project. On March 12, 2025, it was determined that the project continues to qualify for FAST-41 coverage. Corresponding updates to the permitting timetable were posted on May 9, 2025.
