Aspen prepared an EIR for a proposed 230 kV circuit within an existing transmission line right of way (ROW) between Miguel (near Chula Vista) and Mission substations (Mission Valley) in San Diego County. The project included installing a new 230 kV circuit on existing towers along the 35-mile long ROW, as well as relocating 69 kV and 138 kV circuits on 80 new steel pole structures. In addition, Miguel Substation and Mission Substation was modified to accommodate the new 230 kV transmission circuit. The Draft EIR was issued on April 1, 2004, and the public comment period ended on May 17, 2004. The Final EIR was released in June 2004 and construction is complete.
