DOE/EIS-0332; McNary-John Day Transmission Line Project Draft ...

Summary
S-6
Alternatives Description
C – South Side, Highway This alternative is very similar to Alternative B; the proposed line
would cross to the south side of the corridor and highway just before
the Hanford-John Day line enters the right-of-way. This alternative
differs from Alternative B in that the proposed line would stay on
the south side of the highway until the exiting lines crosses the
highway, eliminating two highway crossings of the proposed line.
As with Alternative B, the barn and shed (and possibly the house)
would need to be removed. With this Alternative C, the line would
be about 35 feet closer to the house than with Alternative B.
Corridor Mile 32 Alternatives
A – Parallel Existing Line With this alternative, Bonneville would construct the proposed line
across the tribal-owned property at corridor mile 32, paralleling the
existing lines within the existing right-of-way. About 1,100 feet of
conductor and perhaps one tower would be located on the property.
B – Move Entire Corridor With this alternative, the proposed line would be moved to skirt
around the tribal-owned property. The other two existing lines
would also be moved to avoid the property. This alternative would
require one additional tower for the proposed line. For the existing
lines, eight towers (four for each line) would be removed and ten
new towers (five for each line) constructed for the reroute. New
right-of-way would be purchased from the landowners.
Corridor Mile 35 Alternatives
A – Parallel Existing Line With this alternative, Bonneville would construct the proposed line
across the tribal-owned property at corridor mile 35, paralleling the
existing lines within the existing right-of-way. About 500 feet of
conductor would be located across the property.
B – Move Entire Corridor With this alternative, the proposed line would be moved to skirt
around the tribal-owned property at corridor mile 35. The other two
existing lines would also be moved to avoid the property. No
additional towers would be required for this alternative (compared to
Alternative A). For the existing lines, eight towers (four for each
line) would be removed and eight new towers (four for each line)
constructed for the reroute. New right-of-way would be purchased
from the landowners.
No Action Alternative
The No Action Alternative would be to not build the proposed transmission line. If
Bonneville did not build this line, new generation facilities in the area could not connect
and send power over the transmission system.
