The proposed Ambler Road project covers over 3,000 stream crossings, many species of fish, a keystone legacy (salmon) already under threat, and a massive road construction project in a pristine wilderness ecosystem. What could possibly go wrong?
The devil, as they say, is always in the details.
So what and where are the details that will outline potential impacts on fish, streams, and wetlands habitat and how those impacts are to be assessed and mitigated?
Buried in a plethora of documents. This article follows the key documents: (1) the Right-of-Way (ROW) agreements across federal, state and private lands, (2) The 2020 Joint Record of Decision, and (3) the SF-299, the actual application.
The timeline of key decisions is important because it illustrates the amount of participation of conflicting positions, the massive concerns raised and the power plays that were put into the Ambler Road project development.
Timeline Of Key Decisions
November 2015, the Alaska Industrial Development and Export Authority (AIDEA) submitted a SF-299, a consolidated application for a 250-foot-wide right-of way (ROW) to five federal agencies: BLM, National Park Service, Federal Highway Administration, U.S. Army Corps of Engineers. After agency consultations, AIDEA filed a revised consolidated application with supplemental information in June 2016. Revisions of the SF-299 were submitted in June of 2016.[i] A Communications Amendment was submitted in 2019. Federal Agencies Involved: Bureau of Land Management (BLM), National Park Service (NPS), U.S. Army Corps of Engineers (USACE), U.S. Coast Guard (USCG), and Federal Highway Administration (FHWA). Target Resources: Copper, zinc, lead, gold, and silver deposits in the Ambler Mining District.
AIDEA was established in 1967 by the State of Alaska to increase job opportunities and encourage the economic growth of the state, and specifically to support development of natural resources.
2017-2020, BLM prepared an Environmental Impact Statement for the Ambler Road that considered AIDEA’s proposal along with two alternative routes and a no-action alternative.
July 2020: The Bureau of Land Management (BLM) and the U.S. Army Corps of Engineers issued a joint Record of Decision (ROD) approving the 211-mile industrial access road. The 2020 ROD: Concluded that mitigation measures could manage impacts on wildlife, permafrost, and local access.
August and October 2020, legal challenges were brought against the Project by multiple parties.
January 2021: The BLM officially issued the Right-of-Way Grant (No. F-97112) to the Alaska Industrial Development and Export Authority (AIDEA).
January 2022: AIDEA applied for a 450-foot-wide private, exclusive easement over roughly 125 miles of state-managed land. The route connects the Dalton Highway to the Ambler Mining District. It will remain closed to the public and restricted to mining-related commercial traffic. [ii][iii]
February 2022, the Department of the Interior suspended the BLM ROW and requested a voluntary remand from the U.S. District Court for Alaska. In May 2022, the court granted the remand request, returning the matter to BLM to correct the identified deficiencies.
2022-2023, the BLM prepared a Supplemental EIS to address the deficiencies identified in the remand and to ensure compliance with applicable laws, including the National Environmental Policy Act (NEPA), Federal Land Policy and Management Act (FLPMA), NHPA, and ANILCA. [iv]
January 2024: The Alaska Industrial Development and Export Authority (AIDEA) submitted detailed comments on the Ambler Road Draft Supplemental Environmental Impact Statement (DSEIS) prepared by the Bureau of Land Management (BLM). The submission, which totaled 460 pages including attachments, is part of AIDEA’s ongoing commitment to responsibly develop natural resources and economic opportunities in the Ambler Mining District.[v]
June 2024: The Biden administration reversed course and released a new Record of Decision selecting the “No Action Alternative,” which blocked the project due to irreversible impacts on subsistence uses and permafrost. “The ROD recognized that the harm to subsistence uses would involve “high-likelihood, high-magnitude, long- or permanent-duration impacts over an expansive area for all alternatives.”[vi] This followed the Supplemental Environmental Impact Statement (SEIS) that was jointly prepared by the U.S. Department of the Interior / Bureau of Land Management in cooperation with: Alatna Village Council, Allakaket Village Council, Evansville Tribal Council, Huslia Tribal Council, State of Alaska, Tanana Tribal Council, U.S. Army Corps of Engineers, U.S. Environmental Protection Agency. U.S. Fish and Wildlife Service, National Park Service
April 2025: AIDEA signs resolution No. G25-01 relating to development of the Ambler Road project by moving available funds from the arctic infrastructure development fund into the revolving fund[vii]
June 2025, AIDEA filed a direct appeal to the President of the United States under Section 1106 of the Alaska National Interest Lands Conservation Act (ANILCA).
October 6, 2025, the President approved an appeal by the Alaska Industrial Development and Export Authority (AIDEA) directing Federal agencies, including the BLM, to promptly issue permits to establish the Ambler Road.[viii] The 2020 Record of Decision (ROD) on the Ambler Road project was the approval for right-of-way (ROW) permits for the 211-mile industrial access road in northwestern Alaska.
October 21, 2025, the BLM reissued AIDEA the BLM Right-of-Way Grant, No. F-97112, originally issued January 5, 2021.
The serious concerns of the 2024 Record of Decision recommending “No Action” were over-ridden by the action of the President in 2025 when the 2020 Record of Decision was re-instated, which found that impacts could be sufficiently mitigated. This action eliminated years of intense work on behalf of tribal and community groups in identifying the Ambler Road impacts that likely could not be mitigated.
However, the 2020 ROD does have language in many places that emphasize and describes this dilemma. As prefaced in:
Page 202 : F-69 iii. The extent and permanence of the beneficial and/or detrimental effects that the proposed structures or work may have on the public and private uses which the area is suited: The impacts to the environment are described in the BLM’s FEIS and the Ambler EEA, as well as within this document. The road is expected to remain as long as there is mining within the Ambler Mining District, perhaps up to 50 years. After this the applicant states they would remove the road and reclaim the land. Therefore the impacts and benefits of the project would be long term. The road would leave impacts, regardless of whether it were removed and reclaimed or if it were to remain. It is unlikely that wetlands would restore to previous conditions even with several decades, if the land were to be reclaimed, although their functional capacity would increase after reclamation work. The vast majority of the project area has evolved from natural processes over millennia and has provided food, cultural and spiritual sustenance for native peoples and highly valued wildland recreation uses for others. As described in the Ambler Road FEIS and Ambler EEA, and in this JROD, these uses of subsistence resources and wildlands would remain but would be impacted by construction activities and industrial uses of the road, including access for large scale mines in the Ambler Mining District over the long term.”
The most determinant document for the Ambler Road construction is the SF-299[ix] , consolidated Right-of-Way (ROW) application submitted by AIDEA. It outlines the plans to construct and operate a 211-mile industrial access road from the Dalton Highway to the Ambler Mining District in northwest Alaska.[x] The SF-299[xi] application for the Ambler Road project acknowledges that the proposed 211-mile road will impact fish resources and habitats, citing studies for various stream crossings. Detailed, site-specific mitigation data for these aquatic habitats is deferred for later determination. Review the full Joint Record of Decision regarding the Ambler Road at Alaska DNR.
Here is where the detail comes to light. The Ambler Road SF-299 is a spiderweb of inter-related documents. It remains unclear what operational plans will actually apply as the scope of the project changes. This continues to pose an immense threat to fish and fish habitat as there is no definitive plan for fish. While the SF-299 identifies fish presence it continually minimalizes potential impacts.
Two small examples: Appendix 2E of the SF-299 references fish surveys from 2013-2015, now over 12 years. And, as discussed earlier in this series, the costs and sizing and maintenance of almost 3,000 project culverts[xii] needed may be vastly under-estimated. And on page 2, “No comprehensive assessment of baseline water quality has been conducted to date for the waterbodies crossed by the proposed corridor. With the sheer number of waterbodies within the proposed corridor, no comprehensive baseline data exists that could be correlated with other data collection efforts”
The SF-299 needs to be fully dissected and compared to the original and supplemental Environmental Impact Statements (EIS) as well as the 2024 Record of Decision to fully understand where the gaps are in protective measures for fish and fish habitat.
