Federal Permitting – National Environmental Policy Act (NEPA) Process

DEIS - Public Comment Period Closed

The Bureau of Land Management (BLM) completed the Draft Environmental Impact Statement (“DEIS”) for the Grassy Mountain Project in August 2025. The public comment period for the DEIS was completed in September 2025. During this period, Federal, State, and local agencies, Tribal governments, and the public provided input on potential project impacts and alternatives.

The BLM is now reviewing and incorporating comments received during the DEIS process, and is preparing the Final Environmental Impact Statement (FEIS) and Record of Decision (ROD) expected in January 23, 2026 as per the BLM’s e-planning website.

Overview of the NEPA Process

What is NEPA?

The National Environmental Policy Act (NEPA) requires federal agencies to evaluate the potential environmental, social, and economic impacts of major projects before making decisions. An Environmental Impact Statement (EIS) is a detailed, public-facing document that presents this analysis and considers reasonable alternatives.

An EIS is required under NEPA to ensure that decisions about projects involving Federal land or permits are informed by science, public input, and a thorough assessment of potential impacts. It is a key part of promoting transparency and accountability in the decision-making process.

In 2024, the US government updated the rules under NEPA to make environmental reviews clearer, more consistent, and faster to complete. This new NEPA handbook, released in 2025 by the Department of the Interior, helps Federal agencies apply those changes. It provides updated guidance on how to:

  • Involve the public and Tribes more meaningfully
  • Integrate climate change and environmental justice into reviews
  • Coordinate across agencies to avoid delays
  • Use new tools and approaches (like programmatic reviews or tiering)

Grassy Mountain Gold is following the most current Federal guidance.

Overview of FAST-41?

What is FAST-41 and Why Does it Apply to Grassy Mountain Gold?

FAST-41 refers to Title 41 of the Fixing America’s Surface Transportation Act, a Federal law designed to improve the transparency, coordination, and timeliness of the environmental review and permitting process for certain major infrastructure projects.

Grassy Mountain Gold is one of the few mining projects in the US designated as a FAST-41 with Transparency Project.

The project qualifies under FAST-41 because:

  • It requires Federal environmental review under the National Environmental Policy Act (NEPA) (i.e., an Environmental Impact Statement)
  • It involves significant investment and potential economic development
  • It is subject to multiple Federal approvals, including from the Bureau of Land Management (BLM), and inter-agency coordination (e.g., US Fish and Wildlife, Environmental Protection Agency (EPA))

The new NEPA handbook can be reviewed on the DOI NEPA Handbook webpage.

The status of the permitting process and future updates can be tracked via the BLM’s FAST-41 dashboard.

The State Review Process

Grassy Mountain Gold is the first project to undergo Oregon’s Chemical Process Mining permitting program since its creation

Draft Consolidated Permit Package Issued

In December 2025, the Oregon Department of Geology and Mineral Industries (DOGAMI) released the Draft Consolidated Permit Package, which includes draft operating permits and conditions for the Grassy Mountain Gold Project .

Public Hearing Scheduled

DOGAMI has scheduled a public hearing for January 29, 2026, in Vale, Oregon. The hearing will include project presentations and an opportunity for verbal public comment.

State Public Comment Period (Open)

The public comment period for the Draft Consolidated Permit Package remains open through February 6, 2026. Following the close of this comment period, DOGAMI and participating state agencies will consider public input and make any necessary revisions before issuing the Final Consolidated Permit Package.

Environmental Evaluation (EE) & Technical Review Team (TRT)

The Environmental Evaluation (EE) and supporting technical analyses have been reviewed by the Technical Review Team (TRT)—a multi-agency panel composed of State, Federal, and local experts.

The TRT is currently reviewing comments received during the State public comment period and will continue its analysis as DOGAMI prepares for final permitting decisions.

Environmental Evaluation (EE)

As part of Oregon’s Chemical Process Mining Program, an Environmental Evaluation (EE) was prepared by Stantec on behalf of the state. This document compiles scientific studies and data on topics including:

  • Groundwater and surface water
  • Wildlife and habitat
  • Air quality and noise
  • Cultural and historic resources
  • Reclamation and closure planning

The EE now complements the Draft Consolidated Permit Package (December 2025) and the federal Draft Environmental Impact Statement (DEIS). The EE also includes a detailed socioeconomic impact assessment, which is referenced in the federal DEIS. It outlines projected employment, income generation, and regional economic benefits of the project during construction, operations, and closure.

Technical Review Team (TRT) Process

Ongoing review is being conducted by a Technical Review Team (TRT) coordinated by DOGAMI. The TRT includes State and Federal agencies, local governments, and Tribes. The TRT will review and consider comments received during the public comment period on the Draft Consolidated Permit Package (January–February 2026). Minutes from every public TRT meeting are available on DOGAMI’s website and document the status of reviews, agency comments, and applicant responses.

Access Project Documents

The Environmental Evaluation, Technical Review Team meeting minutes, and related permitting materials are available on DOGAMI’s project webpage.
