Blackhawk to Heybourne 120 kV Transmission Line Project
PROJECT DESCRIPTION:
The BLM Carson City District Office intends to prepare an environmental impact statement (EIS) to analyze the impacts (direct, indirect, and cumulative) resulting from construction of a new 120 kV electrical transmission line and two new substations proposed in a right-of-way (ROW) application from Sierra Pacific Power Company.
The proposed Blackhawk to Heybourne Transmission Line Project (Blackhawk EIS) includes the construction of approximately 34 miles of an electrical 120 kV transmission line through four counties in Nevada, beginning at the proposed new Blackhawk Substation in Storey County. The proposed transmission line runs parallel with existing transmission lines along all but the first four miles in Storey and Lyon Counties and three and a half miles in Douglas County.
From the proposed Blackhawk Substation four new 120 kV transmission lines would run parallel, crossing U.S. Highway 50, for approximately four miles where two of the lines would fold into another existing transmission line north of the Carson River.
From that point the remaining two lines would continue southwest, crossing the Carson River, and running another eight miles to the existing Dayton Substation in Lyon County.
From the Dayton Substation one transmission line would run south over two miles, then west approximately six miles, parallel with existing lines to the existing Brunswick Substation in Carson City.
From the Brunswick Substation the transmission line parallels existing powerlines straight south for approximately seven miles to the existing Prison Hill Switching Station in Carson City.
At this point the line would parallel an existing line south for less than a mile before turning west for approximately three and a half miles in a new corridor through a saddle in Hot Springs Mountain and across the Douglas County water treatment facility, then south for approximately one mile paralleling an existing line and terminating at the proposed new 120 kV Heybourne Substation in Douglas County.
