DEPARTMENT OF ENERGY
Bonneville Power Administration
Floodplain and Wetlands Involvement for BPA's Hot Springs-
Garrison Fiber Optic Project
AGENCY: Bonneville Power Administration (BPA), DOE.
ACTION: Notice of Floodplain and Wetlands Involvement.
-----------------------------------------------------------------------
SUMMARY: BPA proposes to upgrade its existing operational
telecommunications equipment in Northwestern Montana from BPA's Hot
Springs Substation to Garrison Substation, a distance of 190 kilometers
(120 miles). This upgrade will involve replacing existing microwave
equipment with fiber optic cable and equipment. The fiber optic cable
will be strung on existing structures on BPA's Hot Springs-Garrison
line and will use existing access roads and rights-of-way. No new
structures will be needed for this project. This 190 kilometer line
will span both floodplains and wetlands located in the counties of
Sanders, Lake, Missoula, Granite, and Powell, Montana.
In accordance with DOE regulations for compliance with floodplain
and wetlands environmental review requirements (10 CFR Part 1022), BPA
will prepare a floodplain and wetlands assessment and will perform this
proposed action in a manner so as to avoid or minimize potential harm
to or within the affected floodplain and wetlands.
The assessment will be included in the environmental assessment
being prepared for the proposed project in accordance with the
requirements of the National Environmental Policy Act. A floodplain
statement of findings will be included in any finding of no significant
impact that may be issued following the completion of the environmental
assessment.
DATES: Comments are due to the address below no later than October 10,
1994.

Administration, P.O. Box 3621, Portland, Oregon, 97208-3621, phone
number 503-230-5511, fax number 503-230-3984.
SUPPLEMENTARY INFORMATION: Within the transmission line corridor,
wetlands can be found in association with various river systems and
drainages. Many wetlands found along the Clark Fork river are remnants
of old river channels, some of which were isolated during construction
of Interstate 90, while others are due to the natural shifting of the
channels (oxbows). Small wetlands have formed in a few areas adjacent
to small drainages, such as Flint Creek. All wetlands are spanned by
the fiber optic cable and avoided by access roads; therefore, there
would be no direct impacts to wetlands from the proposed project.
Appropriate mitigation measures will be used to reduce potential
indirect impacts to wetlands.
The transmission line corridor crosses or has structures located in
areas identified as 100-year floodplains. These are areas that have a
1-percent chance of being flooded in a given year. The corridor crosses
floodplains associated with the Clark Fork River, Flint Creek,
Rattlesnake Creek, Grant Creek, Butler Creek, Flathead River, Little
Bitterroot River, and Valley Creek.
There are twenty-six structures located in 100-year floodplains. Of
these, three (structures 24/8, 25/2, and 91/4) have been identified as
pulling and tensioning sites. Overall impacts to floodplains would be
short-term and low; the proposed project activities would not alter
floodplain characteristics or create the potential for greater loss of
property or life during flooding. No new access roads or structures
would be needed. At pulling and tensioning sites disturbance would
occur from vehicles and machines, but all three sites are agricultural
and would be returned to their original condition following
construction.
BPA will endeavor to allow 15 days of public review after
publication of this statement of findings prior to implementing the
proposed action.
Maps and further information are available from BPA at the address
above.
