Environmental Review
The EIS process consists of several steps, each with opportunities for you to get involved as we prepare the I-5 Corridor Reinforcement Project EIS (DOE/EIS-0436). We also work with tribal governments and cooperating agencies during this process.

The environmental review process began with a Notice of Intent (74 Federal Register 52482, October 13, 2009) and a letter to the public announcing the scoping process. Scoping is an important time when the public can help BPA identify issues and provide suggestions about the project. The overall goal of the scoping process is to define the scope of issues that will be addressed, analyzed and included in the EIS. The official public scoping period closed Dec. 14, 2009, but BPA accepted public comment up through the publication of the draft EIS.
Draft EIS

The draft environmental impact statement describes the proposed project and why it is needed, discusses the environmental impacts the project would create, and lists mitigation measures that would lessen or eliminate those impacts. BPA released the draft EIS on Nov. 13, 2012 for public review and comment. The official draft EIS comment period closed on March 25, 2013. BPA held drop-in sessions in December 2012 to assist you in your review, and public meetings in January and February 2013 to accept comments on the draft EIS.
Final EIS

BPA accepted comments on the draft EIS from Nov. 13, 2012 to March 25, 2013. The final EIS will include any necessary changes to the EIS, and responses to the comments received during the draft EIS comment period. BPA expects to complete the final EIS in 2015.
Record of decision

After the final EIS is released, BPA will release a record of decision (expected early 2016), which will announce BPA's decision about whether to build the project and describe any commitments for mitigating potential environmental impacts. These and other EIS-related documents will be available for downloading and browsing on this website.

Government-to-government consultation
BPA will consult with Native American tribal governments about the I-5 Corridor Reinforcement Project Environmental Impact Statement.
The Bonneville Power Administration works on a government-to-government basis with Native American tribes. As a part of the government's treaty and trust responsibilities, the government-to-government relationship was formally recognized by the federal government on Nov. 6, 2000, in Executive Order 13175
The outcome of this EIS may affect or apply to tribal resources. Therefore, BPA will meet its federal requirements to consult with affected tribes throughout the development of the EIS. BPA and tribes will jointly evaluate and address the potential effects, if any, of the proposed action. These consultations will be conducted in accordance with Executive Order 13175 "Consultation and Coordination with Indian Tribal Governments" (65 FR 67249), the president's memorandum of April 29, 1994, "Government-to-Government Relations with Native American Tribal Governments" (59 FR 22961), agency-specific guidance on tribal interactions and applicable natural and cultural resource laws and regulations (e.g., National Environmental Policy Act, Endangered Species Act, National Historic Preservation Act, and Migratory Bird Treaty Act). More information is available in BPA’s Tribal Policy.

Cooperating Agencies
When a project could involve more than one federal or state agency, those agencies often work together during the planning and decision-making process. The agency primarily responsible for preparing the environmental impact statement is identified as the lead agency, and the other participating agencies are identified as cooperating agencies. The Council on Environmental Quality regulations for implementing the National Environmental Policy Act also allow for the designation of state and local agencies and Indian tribes as cooperating agencies where appropriate.
BPA is the lead agency for preparation of the EIS. BPA is working with several entities as cooperating agencies, including: the U.S. Army Corps of Engineers (Corps), the States of Washington and Oregon, the Washington Energy Facility Site Evaluation Council and the Oregon Energy Facility Siting Council, and Clark and Cowlitz counties. These federal and state agencies and counties are assisting BPA in evaluating alternative transmission line routes and identifying interests that should be addressed in the EIS.
