Title

Blythe Energy Project (99-AFC-8)

Description

The Department is issuing a Lake and Streambed Alteration Agreement for the project proponent who proposes to construct approximately 67.4 miles of new transmission line from the Buck Substation in Blythe, west to the Julian Hinds Substation near Hayfield. The route will generally follow Southern California Edison's (SCE) existing 500 kV Devers-Palo Verde ("D-PV1") transmission line. Transmission line structures will be concrete, single-pole structures, spaced approximately every 850 feet along the construction corridor, and will be accessed by spur roads constructed from existing utility access roads. The transmission lines will be constructed using conventional cranes for pole installation. Impacts include building spur roads to access pole installation sites across ephemeral washes. It will also include temporary wash disturbances during pulling, tensioning, and splicing activities, and the installation within washes of some flood-resistant pole structures where no alternative meets maximum span widths. There are approximately 120 unnamed ephemeral or intermittent drainages of the Southern Mojave Watershed and 25 unnamed ephemeral or intermittent drainages of the Southern Mojave Watershed and 25 unnamed ephemeral or intermittent drainage of the Hayfield Dry Lake Watershed. The project proposes to impact approximately 145 of these drainages, for a total cumulative impact of 20.5 acres to jurisdictional streambed.
