EA-1383: Final Environmental Assessment

Amendment of Presidential Permit (PP-68) San Diego Gas & Electric Company for Interconnection of Otay Mesa Generating Project to Miguel-Tijuana 230 kV Transmission Line San Diego, California

Otay Mesa Generating Company, LLC (OMGC) proposes to construct a nominal 510 megawatt (MW) combined cycle, natural gas- fired power plant on east Otay Mesa in southwestern San Diego County adjacent to the existing Miguel- Tijuana 230 kV transmission line. OMGC proposes to interconnect the Otay Mesa Generating Project (OMGP) to the SDG&E grid. Interconnection of the OMGP to the SDG&E grid will require significant modification of the existing Miguel-Tijuana transmission line and, therefore, an Amendment to Presidential Permit 68. This Environmental Assessment addresses the environmental impacts of the proposed interconnection activities in accordance with NEPA.
