Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of the proposed construction of the San Diego Gas & Electric (SDG&E) Tie-Line (TL) 637 Wood-to-Steel Project located in central San Diego County, near the communities of Ramona and Santa Ysabel, California. An application for this project was submitted to the CPUC on March 13, 2013 (Application A.13-03-003) and a Decision was issued on February 5, 2014 (Decision D.14-02-04). This site provides access to public documents and information relevant to the California Environmental Quality Act (CEQA) review process.
SDG&E filed an application for a Permit to Construct the TL 637 Wood-to-Steel Project with the CPUC. The CPUC is the CEQA lead agency for this project. The project proposes to fire-harden approximately 14 miles of the existing 69-kilovolt (kV) wood pole power line (TL 637) between the Creelman and Santa Ysabel Substations. SDG&E’s purpose for the project is to increase fire safety and service reliability of the 69 kV power line in a high fire risk area of San Diego County. As proposed by SDG&E, the project would fire-harden the existing system by replacing the existing 69 kV wood pole structures with new weathering steel poles. Work would also be conducted at the Creelman and Santa Ysabel Substations to allow for the wood-to-steel conversions of TL 637. Further, SDG&E is proposing to install a new SDG&E-owned and operated fiber optic cable between the substations on the new TL 637 steel poles.
The proposed project is located in unincorporated San Diego County, between the communities of Ramona and Santa Ysabel, in central San Diego County, California. The location of the proposed project is shown in the Project Location Map.
