Project Description

What's New

The decision approving the proposed action was signed February 9, 2026. The final EA, DR, and FONSI were uploaded to this site page the same day.

This website provides the latest information on this project. Throughout the NEPA process, this website will be updated to include background documents, maps, meeting announcements, published bulletins, and other documents as applicable. Using the contact information listed below, individuals and organizations must submit a written statement to the BLM indicating their interest to serve as a consulting party in the proposed project's Section 106 process. For instructions on how to navigate and use this site, review the Video Tutorial in the upper right corner.

In addition to accepting public input into the proposed project's NEPA process, the BLM is also inviting interested parties to participate in the proposed project's National Historic preservation Act Section 106 process outline at 36 CFR 800. During the Section 106 process, the BLM will consult with interested parties on identifying the area of potential effect, appropriate cultural resource identification efforts, the determination of effects to historic properties, and if necessary, the resolution of adverse effects for the proposed project.
