Project Permitting and Approvals

Community and stakeholder engagement is an important part of our permitting process. Members of the project team have begun preparing and filing permits across the three states, but many of these approval processes take many months and sometimes years to receive a final decision. We will continue to provide you notification of upcoming activities within your communities and we invite you all to connect with the project team to learn more about this project.
