Mead-Phoenix +- 500KV DC Transmission Line Projects: Maps, Diagrams and Tables

摘要

This is the draft environmental impact statement (DEIS) for the proposed Mead-Phoenix +- 500-kV dc Transmission Line Project (DOE/EIS-0107-D) in Arizona and southern Nevada. The DEIS addresses the proposal to construct, operate and maintain a 500-kV direct current (dc) transmission line from Mead Substation near Boulder City in southern Nevada to the proposed Eastwing Terminal near Phoenix, Arizona. There will be alternating current (ac)/dc converter stations at each end of the transmission line. Ancillary facilities include communication facilities for the line and approximately 20 miles of distribution-type lines to the ground electrode for each terminal. Power transfer capability of the dc transmission line would be initially rated at 1600 megawatts (MW) with ultimate capacity of transmitting up to 2200 MW. The DEIS has been prepared to fulfill the requirements of the National Environmental Policy Act of 1969 and related statutes and regulations. The environmental setting of the proposed project area and the environmental consequences of the proposed action and alternative actions, including the no-action alternative, are discussed.
