Alaska Stand Alone Pipeline, also called the North Slope to Central Alaska Pipeline (ASAP), is a proposed natural gas pipeline in Alaska.[1] As of April 2021, according to the U.S. Energy Information Administration, is considered on hold and assumed to be shelved.[2]


The pipeline will run from Prudhoe Bay to Point MacKenzie, Alaska, USA, with a 30-mile lateral line between the main pipeline and Fairbanks.[3]

The Alaska Stand Alone Pipeline (ASAP) is Alaska’s in-state natural gas pipeline project. The low pressure pipeline will run from Prudhoe Bay to Point MacKenzie, with a 30-mile lateral line between the main pipeline and Fairbanks.[1]

The Alaska Gasline Development Corporation (AGDC) in-state natural gas pipeline project’s Environmental Impact Statement (EIS) was issued in 2012. Due to changes in the gas composition, length of the gas line and other factors, AGDC and the U.S. Army Corps of Engineers began work on a Supplemental EIS (SEIS) which is scheduled for public meetings in 2017 with a potential for issuance of a Final SEIS in early 2018. Once the SEIS is complete, construction was anticipated to begin in 2019, with an in-state gas pipeline delivery of gas to communities by 2023. The pipeline would carry up to 500 million cubic feet per day of consumer grade “lean gas.” Lean gas is energy ready for delivery to, and consumption by, customers.[1] As of March 2020, the U.S. Energy Information Administration (EIA) reported the expected start date to be in 2025.[5]

In June of 2018, the U.S. Army Corps of Engineers released its Final Supplemental Environmental Impact Statement (SEIS) for the project. The project falls under the Army Corps of Engineers’ jurisdiction because it’s an in-state project. The SEIS finalization paved the way for three more federal authorizations; a wetlands mitigation plan, an agreement on cultural resources for the National Historic Preservation Act, and a federal right-of-way.[6]

In March of 2019, the Alaska Gasline Development Corp (AGDC) received the last major federal permit it needed before it can decide on its proposed Alaska Stand Alone Pipeline. The permit came from the U.S. Army Corps of Engineers and the Bureau of Land Management (BLM) in a joint record of decision for the ASAP project. An AGDC spokesperson said that the Alaska Stand Alone pipeline is seen as a backup plan while they focus primarily on Alaska LNG Terminal.[7]

According to the U.S. Energy Information Administration, as of April 2021, the project was on hold.[2] The Alaska Gasline Development Corporation noted it was focusing on the Alaska LNG Project, and that the pipeline was a secondary priority.[8]

In September 2023, Enstar Natural Gas asked permission to take over the development of the project from the Alaska Gasline Development Corporation.[9]
