Welcome to the BLM's NEPA website for the Ten West Link Transmission Line EIS

The Ten West Link Draft Environmental Impact Statement (DEIS) and Draft RMP Amendments was published August 31, 2018.  Comments were accepted through November 29, 2018.

Thank you to everyone who reviewed the document, attended a meeting, and/or provided substantive comments on the project.  The BLM is analyzing the comments received, and will use the comments to revise the Final EIS.  We anticipate publishing the Final EIS in March 2019. 



  
 
 
 
 
 
The Draft Environmental Impact Statement (DEIS) analyzes and discloses the potential effects of a transmission line project proposed by DCR Transmission, LLC (DCRT).  The DEIS includes analysis of proposed amendments to the Yuma Field Office Resource Management Plan and California Desert Conservation Area Plan, which would be needed for the project to be approved. 

The proposed project would be sited on state, private and Federal lands, and would provide a connection between the Arizona Public Service Company’s Delaney Substation in Tonopah, Arizona, and the Southern California Edison Company’s (SCE) Colorado River Substation in Blythe, California, by largely following the existing SCE Devers-Palo Verde 500-kV No.1 transmission line in an established utility corridor.  The proposed action would involve approximately 83 miles of public lands along a route spanning roughly 114 miles, with approximately 97 miles in Maricopa and La Paz Counties, Arizona, and 17 miles in Riverside County, California.  

Based on extensive feedback received from Cooperating Agencies and from public scoping, the BLM developed a robust suite of alternatives, which are detailed in the DEIS.  The DEIS  analyzes the potential effects these alternatives would have on human, natural, and cultural resources, as well as determining what measures would be necessary to mitigate or reduce those impacts.

Based on thorough analysis, the BLM’s Preferred Alternative is Alternative 2, the BLM Utility Corridor Route, with some route segment modifications.  The Preferred Alternative spans 126 miles and is mostly located within BLM-designated utility corridors or parallel to existing infrastructure.  Of the 126-mile route, 64% is on BLM-managed public lands, 20% is on private land, 15% on state land, and 1% on Bureau of Reclamation-managed public lands.

The DCRT requested the proposed project because the California Independent System Operator (CAISO) identified a need for additional high-voltage transmission connection between the Delaney and Colorado River substations to support grid reliability and efficiency and state energy policy. Through a competitive bid process, CAISO selected DCRT to permit and construct a 500-kilovolt transmission line to meet that need.
