SUPPLEMENTARY INFORMATION:
srobinson on DSK4SPTVN1PROD with NOTICES
ADDRESSES:
Background
TVA evaluates its dam safety program
regularly (especially as technology and
standards evolve and when more or
better data become available) and
modifies its dams as needed to ensure
the structural integrity of TVA dams and
the safety of the public. Periodic
updates regarding maximum flood
conditions are conducted when
parameters used in flood modeling
change, e.g., probable maximum
precipitation or river operation
guidelines. TVA assumes the most
extreme weather event reasonably
possible when determining maximum
flood conditions of the river system.
TVA’s most recent probable maximum
flood calculations indicate that a worstcase winter storm could cause water to
go over the top of some dams even with
the floodgates wide open, possibly
causing dam failure. Failure of any dam
would result in loss of stored water for
navigation, impacts to fish and wildlife
resources, loss of recreational
opportunities, and possible property
damage, personal injury, and loss of life.
Failure also could result in failures to
downstream dams.
To minimize the potential effects of a
severe flooding event predicted by
revised probable maximum flood
modeling, precautionary measures have
been implemented on top of the earth
embankments at four (Cherokee, Fort
Loudoun, Tellico, and Watts Bar) dams.
These measures included raising dam
elevations about 3 to 4 feet by placing
interconnected, fabric-lined, sand-filled
HESCO containers in order to safely
pass predicted worst-case floodwaters,
to avoid dam overtopping and possible
impacts to the downstream
embankment, and to provide additional
floodwater storage capacity. The
downstream embankment of Watts Bar
Dam has also been strengthened with
concrete matting.
VerDate Mar<15>2010
16:27 Jun 13, 2011
Jkt 223001
TVA must now develop permanent
solutions for the precautionary
measures that were put in place to
correct safety deficiencies identified at
Cherokee, Fort Loudoun, Tellico and
Watts Bar dams. The need for the
proposed action is to prevent the
impacts associated with dam failure.
TVA has developed alternatives that
consider the level of risk reduction to
the public, constructability, potential
environmental impacts, and cost.
Proposed Alternatives
TVA has performed preliminary
internal scoping and identified a No
Action Alternative and two Action
Alternatives: permanent modifications
to dam structures and removal of the
temporary HESCO baskets before the
end of their useful life.
The No Action Alternative is the
current existing condition at the
Cherokee, Fort Loudoun, Tellico, and
Watts Bar dam sites. A permanent
concrete mat structure has been
installed in the downstream
embankment of Watts Bar Dam, and
HESCO baskets have been installed at
Cherokee, Fort Loudoun, Tellico, and
Watts Bar dams. These items would
remain in place and would be
maintained as needed. These temporary
measures were installed to prevent
floodwaters from potentially
overtopping the dams and to ensure the
integrity of the downstream
embankments, thus increasing the
public safety of downstream residents
and the safety of TVA’s critical nuclear
facility operations.
Under the first Action Alternative, the
HESCO baskets would be replaced, and
permanent dam modifications would be
made to each of the four dam structures.
The potential modifications could
include construction of concrete
floodwalls, raising of earth
embankments, or a combination of
floodwalls and raised earth
embankments. The permanent concrete
mat structure in the downstream
embankment of Watts Bar Dam would
remain in place. Under this alternative,
the potential for overtopping of the
dams during a probable maximum flood
event would be prevented. This would
ensure that the integrity of the
downstream embankments would be
maintained and thereby increase the
public safety of downstream residents
and the safety of TVA’s critical nuclear
facilities.
Under the second Action Alternative,
TVA would consider removal of the
temporary HESCO baskets from the dam
structures before the end of their useful
life. The permanent concrete mat
structure installed in the downstream
PO 00000
Frm 00162

embankment of Watts Bar Dam would
remain. This alternative is similar to the
situation at the dams prior to placing
the HESCO baskets on the dams as an
interim solution for management of the
potential maximum flood events. Under
this alternative, overtopping of the dams
would be possible during a very lowrisk probable maximum flood event.
The downstream integrity of the dam
embankments could be compromised,
thus jeopardizing the public safety of
downstream residents and the safety of
TVA’s critical facilities. The analysis of
this alternative would contain a
discussion/justification regarding the
reasons for placing the baskets on top of
the dams to address this low-risk event.
Proposed Issues To Be Addressed
The environmental review will
contain descriptions of the existing
environmental and socioeconomic
resources within the area that would be
affected by construction, operation, and
maintenance of the proposed permanent
dam modifications. Evaluation of
potential environmental impacts to
these resources will include, but will
not necessarily be limited to, the
potential impacts on water quality,
aquatic and terrestrial ecology,
endangered and threatened species,
wetlands, aesthetics and visual
resources, recreation, land use, historic
and archaeological resources, and
socioeconomic resources. The need and
purpose of the project will be described.
The final range of issues to be addressed
in the environmental review will be
determined, in part, from scoping
comments. The preliminary
identification of reasonable alternatives
and environmental issues in this notice
is not meant to be exhaustive or final.
Public and Agency Participation
The environmental review is being
prepared to inform decision makers and
the public about the potential
environmental effects of TVA’s options
for minimizing the potential effects of a
severe flooding event predicted by
revised probable maximum flood
modeling. The draft EA or EIS is
anticipated to be available in late
summer 2011. Any changes to this
schedule will be posted on the TVA
Web site: https://www.tva.com/
environment/reports/index.htm. The
environmental review process will also
serve to inform the public and the
decision makers of the reasonable
measures that would be implemented to
minimize adverse impacts. Other
Federal, state, and local agencies and
governmental entities are invited to
provide scoping comments. These
agencies include, but are not limited to,

In accordance with Part 232 of Title

Administration (FRA) grant a
modification of the single car air brake
test procedures as prescribed in 49 CFR
232.305(a). FRA assigned the request
Docket Number FRA–2010–0174.
PATH operates a fleet of 25 flat cars
in consist with revenue cars utilized as
locomotives in ‘‘work’’ trains, where the
friction brakes operate in conjunction
with the RT2 system of straight air brake
employed on PATH cars. The single car
air brake test described in Association of
American Railroads (AAR) S–486
(incorporated by reference in 49 CFR
232.305) is intended for freight cars
with automatic brake systems that are
significantly different than the RT2
system utilized by PATH. As such,
PATH believes that a brake system
inspection and testing procedure similar
to that performed on PATH MU
locomotives is required since a
conventional AAR S–486 single car air
brake test cannot be performed on these
flat cars.
PATH requests a modification to the
single car air brake test procedure
required in 49 CFR 232.305 by the
adoption of ‘‘Procedure for the
Inspection/Testing of PATH Flat Cars’’
