Please review this site for:

• information on the status and schedule of the Environmental Impact Statement (EIS)
• documents and references available for review
• opportunities for public involvement
• methods to submit comments during designated public comment periods

This website will be updated throughout the project. Please check back often for updates.

Draft EIS Public Review Period

Public involvement is an integral part of the National Environmental Policy Act (NEPA) process. The public has an important role in providing input during this process to help NGB and DAF make informed decisions regarding the proposal.

The public scoping period occurred in the summer of 2024, which included a public meeting in June.  Comments received were reviewed and incorporated into the document as appropriate. The Draft EIS is now available for public review on the Documents page. Information on the public review and comment period is available on the Get Involved page.
