CASE FILE NUMBER: CACA47658
DOCUMENT NUMBER(S): CA-670-2006-060, DOI-DES-07-58

On Dec. 18, 2008, the California Public Utilities Commission (CPUC) approved a proposal by San Diego Gas & Electric Company (SDG&E) to construct a new,  90-mile, 500-kilovolt (kV) transmission line from the Imperial Valley Substation (in Imperial County, near the City of El Centro) to a new Suncrest Substation (near Alpine, Calif.) and a new 27-mile 230-kV transmission line that includes both overhead and underground segments from the new Suncrest Substation to the existing Sycamore Canyon Substation (near Marine Corps Air Station Miramar).  On Feb. 24, 2009, the BLM approved a temporary right-of-way grant for construction and a long-term right-of-way grant for the operation and maintenance of the transmission lines where they cross approximately 49 miles of public lands in Imperial and San Diego counties. 

Upon obtaining project approvals from the CPUC and the BLM, SDG&E began the process of completing final project design and engineering.  As is common, some project components were modified as engineering was completed. Modifications result from compliance with adopted mitigation measures requiring resource avoidance to minimize or avoid environmental impacts and final engineering design requirements.  In addition, some project components were relocated to accommodate landowner location preferences in compliance with mitigation requirements.   After careful review of the proposed modifications, the CPUC and BLM determined that the changes to the Sunrise Powerlink Project are within the scope of the existing project approvals and the CPUC began issuing notices to proceed for construction of project components on private lands.  On Feb. 2, 2011, the BLM issued a notice to proceed for construction within the fenceline of the existing Imperial Valley Substation and on April 4, 2011, issued a  second notice to proceed authorizing construction of overhead transmission on the public lands crossed by the project.
