Current Project Status

August 2017 - AIDEA's Consolidated SF299 ANILCA application for the Ambler Access project was accepted by 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) with an effective date of June 30, 2016. BLM will be the lead agency for the EIS, along with NPS taking lead on the EEA per ANILCA Section 201(4)(d).

Current Activities


  • AIDEA and BLM have been working on drafting a scope of work for a third party contractor that will work on the preparation of the EIS.
  • BLM is meeting with cooperating agencies regularly.
  • On February 28, 2017, the BLM filed a Notice of Intent in the Federal Register stating its decision to prepare an Environmental Impact Statement (EIS) for the proposed Ambler Access industrial road and an extension of time with regard to the timing of the scoping process under the National Environmental Policy Act (NEPA).

Why Ambler Access?

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 Ambler Access application was filed pursuant to ANILCA § 201(4).

What is Ambler Access?

The Ambler Access project could provide surface access to the Ambler Mining District, home to several known large prospects, including Arctic, Bornite, 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 provided for in the Alaska National Interest Lands Conservation Act (ANILCA).

What is AIDEA?

AIDEA is a public corporation of the State of Alaska, created in 1967 by the Alaska Legislature "in the interests of promoting the health, security, and general welfare of all the people of the state, and a public purpose, to increase job opportunities and otherwise to encourage the economic growth of the state, including the development of its natural resources, through the establishment and expansion of manufacturing, industrial, energy, export, small business, and business enterprises..."
