Project Description

Southern California Edison (SCE) is proposing to demolish segments of their existing rights-of-way and build a new alignment to remediate discrepancies (proposed action) across approximately 262 miles of existing 115 kilovolt subtransmission lines, collectively referred to as the Ivanpah-Control subtransmission line, spanning Inyo, Kern, and San Bernardino Counties, California. SCE proposes to replace existing steel lattice towers with steel tubular monopoles throughout the line. See segments below for details.
 

The northern/ western terminus is the Control Substation, approximately five miles west of the city of Bishop, California; the southern/eastern terminus is at Coolwater Substation, approximately nine miles east of the city of Barstow, California. Southern California Edison proposes the following activities:

  • Segment 1 (126 miles): The subtransmission lines would be rebuilt before demolition in a new alignment near or adjacent to, but outside, the existing right-of-way. Approximately 1,161 existing structures would be removed; 905 new structures would be installed. (CACA106266585 (formerly CARI-000966 and CACA105981265 (formerly CARI-000968, Inyo Kramer)

  • Segment 2 (48 miles): The subtransmission line would be rebuilt before demolition in a new alignment near or adjacent to, but outside the existing right-of-way. Approximately 390 transmission structures would be removed; 342 new structures would be installed. (CACA106074002 (formerly CACA021596) Bishop- Kramer- Victor)

  • Segment 3N (44 miles): The subtransmission line would be reconductored. Reconducting means to replace the cable or wire on an electric circuit, typically a high-voltage transmission line, usually to afford a greater electric-current-carrying capability. Approximately 43 existing structures would be removed; 45 new structures would be installed on existing lattice towers. Some new steel monopoles may be installed. (CACA105860217 (formerly CACA056457), Kramer Coolwater)

  • Segment 3S (44 miles): The subtransmission line would be reconductored. Reconducting means to replace the cable or wire on an electric circuit, typically a high-voltage transmission line, usually to afford a greater electric-current-carrying capability. Approximately 42 existing structures would be removed; 42 new structures would be installed on existing lattice towers. Some new steel monopoles may be installed. (CACA106225201   (formerly CACA055111), Kramer-Tortilla)

  • Segment 4 (98 miles): Effective June 2024, this segment has been removed by SCE from their original proposal.  SCE is conducting a reevaluation of this existing subtransmission line operations and potential remediation needs. 


 

Visual Resource Management

      Provided in the document section are maps for each segment and the agency selected Key Observation Points (KOPs). Simulations of the type of structure which are proposed are displayed in the pdf files.  Contrast Rating sheets are also available with the simulation files.

 

Your comments are critical to the BLM's EIS analysis of the impacts to the human environment and your natural resources.

How to Comment Effectively


 

Your participation is an important part of the decision-making process. We need your feedback to identify issues that may occur if the Project moves forward. The most effective comments are those that provide useful information to the agencies. To make the best use of your input, here are some points to consider when making a comment about the Project:

·     - Identify potentially affected resources, applicable laws, policies and regulations, or reasonably foreseeable actions relevant to the project.

·     - Highlight information, data, and/or analysis the BLM might use when developing alternatives and considering the impact of the proposed project or alternatives.

·     - Identify – based on factual evidence – potential deficiencies in the scope of analysis or methodology or assumptions proposed for use in the environmental analysis

·     - Avoid comments that state, “I am in favor of this Project,” or “I am opposed to this Project.”

·     - Remember that the more clear, concise, and relevant to the Project your comments are, the more effective and useful they will be in improving the environmental impact statement and affecting the BLM’s decision.

 

·     - Make sure you submit your comments within the timeframe announced. This ensures the BLM will have all concerns documented for use in the environmental impact statement.
