Current Project Status

February 2017 - Consolidated SF299 ANILCA applications have been filed with federal agencies, including the National Park Service (NPS), the U.S. Army Corp of Engineers (USACE), Bureau of Land Management (BLM), U.S. Coast Guard (USCG), and the U.S. Federal Highway Administration (FHWA). NPS, USACE, BLM, and FHWA have accepted the application to move forward and have determined that BLM will be the lead agency for the EIS, along with NPS taking lead on the EEA per ANILCA Section 201.4(d). A Project Kickoff meeting with State and Federal agencies was held in early December 2016 to discuss next steps. (See below).

  • AIDEA and BLM are in the process of revising the scope of work for the third party contractor on the EIS.
  • BLM are in the process of publishing the Notice of Intent (NOI) expected between March 2017 and May 2017.
  • NPS and FHWA are working on the EEA.

Where is the Ambler Mining District?

ANILCA established 10 new federal parks, preserves, and monuments throughout Alaska while guaranteeing certain rights of access for subsistence, hunting, fishing, recreational and other economic and social purposes, including ensuring access to and from resource development areas within the State. In balancing these interests, Congress recognized the mineral potential of and the specific need for access to the Ambler Mining District to ensure the economic and social needs of the people of Alaska are met. Section 201(4) of ANILCA therefore provides a specific guarantee of access to the Ambler Mining District for these purposes. The AMDIAP application was filed pursuant to ANILCA ยง 201(4).

What is AMDIAP?

The AMDIAP project could provide surface access to the Ambler Mining District, home to several known large prospects, including Arctic (owned by Trilogy Metals Inc.), Bornite (owned by NANA Regional Corporation, Inc.), Sun, and Smucker, and enable further exploration and development of the area's resources, providing for economic development. The project design is modeled on AIDEA's successful DeLong Mountain Transportation System (DMTS), which includes an industrial access road from the Red Dog Mine to the DMTS port. AIDEA worked with private industry to develop the DMTS industrial access road, and the costs of road construction were paid back through tolls on road use. AMDIAP, once complete, will provide access to the Ambler Mining District through Gates of the Arctic National Preserve. This access is guaranteed in the Alaska National Interest Lands Conservation Act (ANILCA).

What is AIDEA?
