ASAP — The In-state Pipeline Project
April 2010: HB 369 mandated that Alaska Housing Finance Corporation (AHFC)
facilitate development of a plan for an in-state pipeline project.
July 2010: AHFC established the Alaska Gasline Development Corporation
(AGDC) as a subsidiary corporation to take over project planning and execution.
April 2013: HB 4 mandates AGDC to advance an in-state gas pipeline from
North Slope to Fairbanks and Southcentral to an open season and sanction.
ASAP is that project: the Alaska Stand Alone Pipeline.
Also known as the in-state pipeline.

Alaska’s Energy Situation
North Slope energy rich
30+ Trillion cubic feet of
natural gas
Cook Inlet Basin in decline
Creating uncertainty as early
as 2018
Cost of residential heat
Fairbanks heating oil
~$30/MMBTU
Cook Inlet natural gas $9 $10/MMBTU

2013 Legislative Action – AGDC & HB4
Authorizes AGDC to construct gas pipeline from Prudhoe Bay to
Fairbanks and Southcentral Alaska
Established a new public corporation
Authorizes AGDC to work on ASAP plus other projects, issue bonds, and
determine ownership model
Established a 7-member Board of Directors
Authorizes AGDC to issue revenue bonds
Creates new regulatory framework for contract carriers
Requires all state departments, agencies, and public corporations to
work expeditiously with AGDC on permits and authorizations
Provided $355 million in 2013 to advance the ASAP project to open
season and sanction

ASAP –Planned Material Tests
• Working with Potential Material Vendors
• Expecting Pipe to be Tested by Summer
• Planning both small scale and full scale
tests
• Small scale tests to fully identify material
inputs to project predictive models
• Full scale tests to validate the project
predictions
