NUCLEAR REGULATORY COMMISSION
[Docket No 50-391]
Tennessee Valley Authority; Watts Bar Nuclear Plant, Unit 2;
Environmental Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (NRC) is considering
extending the latest construction completion date specified in
Construction Permit No. CPPR-92 issued to Tennessee Valley Authority
(permittee, TVA) for the Watts Bar Nuclear Plant (WBN), Unit 2. The
facility is located at the permittee's site on the west branch of the
Tennessee River approximately 50 miles northeast of Chattanooga,
Tennessee.
Environmental Assessment
Identification of Proposed Action
The proposed action would extend the latest construction completion
date of Construction Permit No. CPPR-92 from December 31, 2010 to March
31, 2013. The proposed action is in response to the permittee's request
dated May 8, 2008. This request superseded an earlier letter dated
March 6, 2008.
The proposed extension will not allow any work to be performed that
is not already allowed by the existing construction permit. The
extension will merely grant the permittee more time to complete
construction in accordance with the previously approved construction
permit.
The Need for the Proposed Action
The proposed action is needed to give the permittee adequate time
to complete construction of WBN Unit 2. In a July 14, 2000 letter, TVA
confirmed that
[[Page 36578]]
WBN Unit 2 met the NRC's definition of a deferred plant, as described
in Generic Letter 87-15, ``Policy Statement on Deferred Plants.''
Subsequently, on August 3, 2007, TVA informed the Commission of its
intent to complete construction and licensing of WBN Unit 2 by April 1,
2012; this letter was submitted in accordance with the Policy Statement
on Deferred Plants. TVA provided information requested by the Policy
Statement, and also informed the Commission that it would resume
construction activities no sooner than December 3, 2007. These
activities are within the scope of the existing construction permit,
which expires December 31, 2010.
Environmental Impacts of the Proposed Action
The environmental impacts associated with the construction of the
facility have been previously discussed and evaluated in TVA's Final
Environmental Statement for construction (FES-CP) of WBN, Units 1 and
2, issued on November 9, 1972. NRC staff evaluated the environmental
impacts of construction and operation of this plant, issuing comments
on TVA's FES-CP as part of its review. In December 1978, NRC staff
issued NUREG-0498, ``Final Environmental Statement Related to Operation
of Watts Bar Nuclear Plant Units 1 and 2,'' for the operating-license
stage (FES-OL), addressing environmental impacts of construction
activities not addressed previously in TVA's FES-CP. The activities
included: (1) Construction of the transmission route for the Watts
Bar--Volunteer 500 kV line, (2) construction of the settling pond for
siltation control for construction runoff at a different location from
that originally proposed in the FES-CP, and (3) the relocation of the
blowdown diffuser from the originally proposed site indicated in the
FES-CP. The staff addressed the terrestrial and aquatic environmental
impacts in the FES-OL, as well as historic and archeological impacts,
and concluded that the assessment presented in the FES-CP remains
valid.
NUREG-0498, Supplement 1 was issued in April 1995. Environmental
issues evaluated included changes to regional demography, natural
resource use, meteorology, ecology, impacts to humans and the
environment, severe accident mitigation design alternatives, and
socioeconomic impacts, including environmental justice issues. The
staff concluded that there were no significant changes to the
environmental impacts discussed in the 1978 FES-OL due to changes in
plant design or operation, or changes in the environment. Furthermore,
the staff concluded that no additional impacts not previously discussed
in the NRC's 1978 FES-OL related to construction of Unit 2 were
expected.
On February 15, 2008, TVA submitted ``Watts Bar Nuclear Plant
(WBN)--Unit 2--Final Supplemental Environmental Impact Statement
[FSEIS] For the Completion and Operation of Unit 2,'' to the NRC. This
FSEIS was completed in June 2007, and was submitted in support of TVA's
operating license application for WBN Unit 2. It also includes TVA's
evaluation of the environmental impacts of construction.
The licensee has no plans to construct additional transmission
lines or disturb any land not discussed in previous environmental
reviews. Impacts on the Federal threatened and endangered species list
issued by the Fish and Wildlife Service were evaluated in previous NRC
environmental reviews. No additional impacts are expected.
Completed construction of WBN Unit 2 includes major structures such
as the containment, turbine building, control building, and equipment
such as the reactor pressure vessel, reactor coolant system piping, and
steam generators. Installation of equipment shared with WBN Unit 1,
such as diesel generators, was completed prior to issuance of the Unit
1 operating license in 1996. The majority of construction activities
will take place within structures already completed. Therefore, most of
the construction impacts discussed in the FES have already occurred. As
discussed in TVA's FSEIS, additional onsite construction environmental
impacts will be small, mitigated by use of good construction practices.
Socioeconomic impacts are similar to those previously evaluated by
the NRC. As construction proceeds, workers moving to the area will
increase demand for services such as schools and recreational
facilities. In its June 2007 FSEIS, in anticipation of a decision to
resume construction, TVA stated that it ``...would designate certain
counties as impacted by the construction process. This [designation]
would make them eligible for a supplemental allocation from TVA's
annual tax equivalent payment under Tennessee law. These funds could be
used by counties to address impacts on county services.'' These
payments mitigate the effects of new workers living in the area.
The requested extension of the construction permit only extends the
period of construction as described in the FES, and does not involve
any different impacts as described and analyzed in the original and
updated environmental impact statements. The cumulative impacts of the
extended construction period are small, and mitigated, as discussed
above.
Based on the foregoing, the NRC staff has concluded that the
proposed action would have no significant environmental impact. Since
this action would only extend the period of construction activities
described in the FES, it does not involve any different impacts or a
significant change to those impacts described and analyzed in the
original environmental impact statement. Consequently, an environmental
impact statement addressing the proposed action is not required.
Alternatives to the Proposed Action
A possible alternative to the proposed action would be to deny the
request, or the no-action alternative. This alternative would result in
expiration of the construction permit for Watts Bar, Unit 2. This
option would require submittal of another application for construction
in order to allow the permittee to complete construction of the
facility with no significant environmental benefit. The environmental
impacts of the proposed action and alternative action are similar.
Denial of the request could also result in TVA seeking other
sources of electrical power. Siting and constructing new power
generating facilities would result in their own environmental impacts,
and does not provide an obvious environmental benefit versus the
proposed construction permit extension, especially given the large
degree of construction already completed for WBN Unit 2.
Alternative Use of Resources
This action does not involve the use of resources not previously
considered in the FES for Watts Bar, Units 1 and 2.
Agencies and Persons Contacted
In accordance with its stated policy, on May 28, 2008, the staff
consulted with officials from the State of Tennessee, including Alan
Leiserson, Legal Services Director of the Tennessee Department of
Environment and Conservation, regarding the environmental impact of the
proposed action. The State officials had no comments.
Finding of No Significant Impact
On the basis of the environmental assessment, the NRC concludes
that this action will not have a significant effect on the quality of
the human environment. Accordingly, the NRC has determined not to
prepare an
[[Page 36579]]
environmental impact statement for this action.

request for extension dated May 8, 2008. Documents may be examined,
