ID 230kV Transmission Line and Substation Expansion - Imperial Valley to Dixieland Substations
Document Type
MND - Mitigated Negative Declaration

Document Description
Proposed construction of a 230kV transmission line and substation improvements between the Imperial Valley and Dixieland Substations. The transmission line route would be approximately 7 miles long in unincorporated Imperial County largely on federal lands managed by the Bureau of Land Management. A new, approximately 140-foot (ft) right-of-way from the Bureau of Land Management would be necessary to accommodate the transmission line route. The project would include 53 pole structures to support the line and a 16-ft wide maintenance road. Substation improvements would involve a 300 ft by 180 ft eastward expansion of the Dixieland Substation at the northern end of the transmission line route, and a new Liebert Substation immediately north of the existing Imperial Valley Substation at the southern end of the route.
