   Welcome to the home page of the Alaska Stand Alone Pipeline (ASAP) SEIS

The Alaska Stand Alone Pipeline (ASAP) Project comprises of a natural gas conditioning facility (GCF) capable of producing an annual average 500 million standard cubic feet per day (MMscfd) of utility-grade natural gas at peak capacity and a 1,480 pound per square inch (psig) natural gas pipeline. The pipeline is a 733-mile long, 36-inch-diameter natural gas transmission mainline extending from the Gas Conditioning Facility near Prudhoe Bay south to a connection with the existing ENSTAR pipeline system in the Matanuska-Susitna Borough. An approximately 30-mile-long, 12-inch-diameter lateral pipeline will connect the mainline to Fairbanks. The proposed pipeline will typically be buried with a minimum cover of 30 inches and a bottom-of-ditch depth of 6 to 8 feet except at possible fault crossings, elevated bridge stream crossings, pigging facilities, and block valve locations. The pipeline system will be designed to transport natural gas that will be accessible to and useable by communities, government entities, and natural resource development projects.

The ASAP route will generally parallel the Trans-Alaska Pipeline System (TAPS) and Dalton Highway corridor to near Livengood, northwest of Fairbanks. At Livengood, the mainline route will continue south, to the west of Fairbanks and Nenana. The pipeline will bypass Denali National Park and Preserve to the east and will then generally parallel the Parks Highway corridor to Willow, continuing south to its connection into ENSTAR's distribution system at MP 39 of the Beluga Pipeline southwest of Big Lake. The Fairbanks Lateral tie-in will be located approximately 2.5 miles south of the Chatanika River crossing at MP 440 of the mainline. From the mainline tie-in point, the Fairbanks Lateral pipeline will traverse east over Murphy Dome, following the Murphy Dome and Old Murphy Dome Roads, and then extend southeast into Fairbanks.

The Alaska District, U.S. Army Corps of Engineers (Corps) has been designated the lead federal agency and the U.S. Bureau of Land Management (BLM), National Park Service (NPS), U.S. Environmental Protection Agency (EPA), U.S. Fish and Wildlife Service (USFWS), U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA), and the Alaska Department of Natural Resources State Pipeline Coordinator's Office (SPCO) are participating as cooperating agencies in the Supplemental Environmental Impact Statement (SEIS) development process.
