NPS EEA Draft Document

In June 2016, AIDEA submitted a Consolidated SF299 ANILCA application for the Ambler Access project. The application was accepted by federal agencies, including the NPS, the U.S. Army Corp of Engineers (USACE), the BLM, U.S. Coast Guard (USCG), and the U.S. Federal Highway Administration (FHWA) with an effective date of June 30, 2016. The BLM will be the lead agency for the Environmental Impact Statement (EIS), along with NPS taking lead on the Environmental and Economic Analysis (EEA) per ANILCA Section 201(4)(d).

  • Ambler Road Environmental Impact Statement-Scoping Summary Report
  • The Draft EEA expected completion in July 2019

The Bureau of Land Management (BLM) is developing an Environmental Impact Statement (EIS) under the National Environmental Policy Act and in accordance with the Alaska National Interest Lands Conservation Act to evaluate whether to grant a right-of-way for the Ambler Road across BLM-managed lands. The following is the timeline for BLM's EIS and ROD on the project.

  • The NPS on February 28, 2017 filed a NOI in the Federal Register for an extension of time regarding ANILCA Sec. 201(4) [16 U.S.C. 410hh(4)] that requires the preparation of an environmental and economic analysis (EEA) that by statute will be prepared in lieu of an environmental impact statement for the portion of the proposed industrial road that would go across the Western (Kobuk River) unit of Gates of the Arctic National Preserve. Under ANILCA, the FHWA is working with the NPS on this portion of the process.

    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..."
