Bonneville Power Administration

Hooper Springs Transmission Project

AGENCY: Bonneville Power Administration (BPA), Department of Energy 

ACTION: Notice of availability of Record of Decision (ROD).


SUMMARY: This notice announces the availability of the ROD to implement 
the Hooper Springs Transmission Project in Caribou County, Idaho. BPA 
has decided to implement the South Alternative's Option 3A (Option 3A) 
identified in the Hooper Springs Transmission Project Final 
Environmental Impact Statement (DOE/EIS-0451, January 2015). Option 3A 
consists of: (1) A new 138/115-kilovolt (kV) Hooper Springs Substation 
located near the city of Soda Springs, Idaho; (2) a new, approximately 
24-mile-long, double-circuit 115-kV transmission line extending 
generally north then east from the Hooper Springs Substation to a new 
BPA connection facility that will connect the new line to Lower Valley 
Energy's (LVE) existing transmission system in northeastern Caribou 
County; (3) a new, approximately 0.2-mile-long, single-circuit 138-kV 
transmission line extending generally south from the Hooper Springs 
Substation to

PacifiCorp's existing Threemile Knoll Substation to connect the new 
line to the regional transmission grid; and (4) required ancillary 
facilities such as access roads.
    The new Hooper Springs Substation will be constructed as a 138/115-
kV substation, meaning that it will include a transformer capable of 
converting 138-kV electricity to 115-kV electricity. BPA will acquire 
100-foot-wide right-of-way for the length of the 115-kV line. 
Approximately 174 new double-circuit 115-kV steel structures, ranging 
in height from 55 to 120 feet with an average span length between 
structures of 730 feet, will be installed in this new right-of-way. The 
BPA connection facility will be located about two miles southeast of 
the intersection of Blackfoot River Road and Diamond Creek Road and 
will consist of overhead line disconnect switches to connect the new 
115-kV line to the existing LVE line. For the single-circuit 138-kV 
transmission line, two wood, H-frame structures approximately 80 to 85 
feet tall will be installed within a new 125-foot-wide right-of-way. A 
fiber optic cable also will be installed along the 138-kV transmission 
line. About 14 miles of new access roads will be constructed and about 
2.4 miles of existing access roads will be improved or reconstructed. 
All mitigation measures identified in the EIS are adopted.
