Regulatory Approvals

The successful siting of a long-haul transmission project is a lengthy, complex process.

Through environmental evaluation and stakeholder participation, the Clean Line team along with land, engineering, and environmental specialists will study and review many variables that will determine suitable corridors for the Centennial West Clean Line. This process includes review and evaluation of potential project impacts, including but not limited to, federal, state and local managed lands, heavily populated communities, recognized tribal lands, areas with high resource value, known cultural resources, water resources, and federal and state protected species. In addition, engineering considerations such as corridor length and type of terrain to be traversed will also be evaluated. After receiving additional stakeholder input and conducting further environmental studies, we will identify a preferred route, as well as alternative routes.

The Centennial West Clean Line project team understands the value of participating in various regional and sub-regional transmission planning initiatives.  For instance, Centennial West Clean Line is a member of the Western Electricity Coordinating Council (WECC), WestConnect, and the Southwest Area Transmission (SWAT) sub-group.  Members of the Centennial West Clean Line project team attend and participate in transmission planning stakeholder meetings.  These allow various entities to discuss where the electric grid will be in 10-20 years and how it will incorporate renewable energy with a focus on reliability, emissions reductions, and network upgrades.

In January 2011, Clean Line submitted an application for right-of-way across Federal lands and a preliminary Plan of Development to the Bureau of Land Management (BLM).  This is the first step towards completion of an Environmental Impact Statement (EIS) under the National Environmental Policy Act of 1969 (NEPA). The EIS will be prepared under the guidance of a lead federal agency. Other federal agencies, along with involved state, tribal and local entities, may act as cooperating agencies in the preparation of the EIS.  Part of the objective of NEPA includes bringing together all of the relevant federal and state agencies so all environmental concerns can be clearly documented and addressed in one process. Throughout the NEPA process, the public will have opportunities to voice their concerns through public meetings and written comments.  The final goal of an EIS is to provide the lead agency with a comprehensive understanding of environmental impacts and mitigation measures so that the agency can issue a Record of Decision on its proposed actions. The Bureau of Land Managment and the Western  Area Power Administration have been selected as co-lead agenices for the Centennial West NEPA review process.

In addition to the regulatory processes outlined above, Clean Line will comply with all other applicable federal, state and local regulations.
