Bonneville Power Administration
Central Ferry to Lower Monumental 500-kilovolt Transmission Line
Project
AGENCY: Bonneville Power Administration (BPA), Department of Energy
(DOE).
ACTION: Notice of Availability of Record of Decision (ROD).
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of the ROD to implement
the Central Ferry--Lower Monumental 500-kilovolt (kV) Transmission Line
Project in Garfield, Columbia, and Walla Walla counties, Washington.
BPA has decided to implement the Combination A Alternative identified
in the Central Ferry--Lower Monumental 500-kV Transmission Line Project
Final Environmental Impact Statement (DOE/EIS-0422, February 2011). The
Combination A Alternative consists of constructing a new 500-kV single-
circuit transmission line from BPA's new Central Ferry Substation near
the Port of Central Ferry in Garfield County generally west through
Garfield, Columbia, and Walla Walla counties to BPA's existing Lower
Monumental Substation in Walla Walla County, a distance of about 38
miles. The transmission line route begins at the new Central Ferry
Substation along the Snake River, and runs southwest for about 11 miles
mostly parallel to and about 1,200 to 2,500 feet (about \1/4\; mile to
[frac12] mile) south of BPA's two existing Little Goose-Lower Granite
500-kV steel lattice transmission lines. The route then angles away
from the existing lines and proceeds southwest for about 6 miles before
crossing the Tucannon River directly north of the town of Starbuck. The
route then proceeds west for about 20 miles from the Tucannon River
crossing to BPA's existing Lower Monumental Substation. BPA will
acquire new 150-foot-wide right-of-way for the entire length of the new
line. Approximately 161 new lattice steel transmission towers, ranging
in height from about 104 to 189 feet with an average span length
between towers of about 1,200 feet, will be constructed in the new
right-of-way. The conductor and overhead ground wire for the new
transmission line will be placed on these towers, and counterpoise
would be buried in the ground at selected towers. Construction of the
new line also will include the upgrade of about 5 miles of existing
access roads, and the construction of about 38 miles of new access
roads. Power circuit breakers, disconnect switches, and other
electrical equipment will be installed at Lower Monumental Substation.
In the vicinity of the Lower Monumental Substation, six existing steel
lattice towers that support existing transmission lines in this area
will be relocated to allow entry of the Central Ferry-Lower Monumental
transmission line into the substation. Fiber optic cable will be
installed along a portion of the new line. All mitigation measures
identified in the EIS are adopted.
