EIS Process


An EIS is a document that provides impartial, comprehensive discussion of a project’s potential significant adverse impacts, reasonable alternatives, and proposed measures to avoid or minimize impacts. An EIS provides decision makers with information to consider in making permitting and approval decisions. It does not constitute a decision or approval on its own.


The first step in the development of an EIS is called scoping. During scoping, agencies, tribes, local communities, organizations, and the public may comment on factors to be analyzed and considered in the EIS.

Specifically, the scoping process is intended to collect input on the following topics:

  • Reasonable range of alternatives
  • Potentially affected resources and areas of impact
  • Potential measures to avoid, minimize, and mitigate effects of the proposal
  • During the scoping period, Enterprise Services and its consultants hosted public meetings, both in-person and online, and solicited comments from the public.

Scoping concluded on Nov. 13, 2018.

Draft EIS

The Draft EIS will include detailed information about a range of potential alternatives, their potential environmental impacts, and what could be done to avoid or minimize those impacts. The Draft EIS will be released for review and comment by all interested parties. The comment period for the Draft EIS will be similar to scoping, including similar ways to comment and both online and in-person public meetings.

Final EIS

Following the Draft EIS comment period, the project team will compile, review, and consider comments submitted on the Draft EIS. A Final EIS will be prepared and will include a preferred alternative. The Final EIS may be used by agencies to inform permitting decisions for the proposed project.

Enterprise Services has selected an interdisciplinary team of consultants to prepare the EIS. The interdisciplinary team has specialty experience in EIS development and expertise in the disciplines that will be studied.

Project timeline including Phase 1: Planning, Phase 2: Environmental Impact Statement, and Phase 3: Implementation. Public comment periods occur in Late 2018 during scoping and 2020 following release of the Draft EIS.
