NUCLEAR REGULATORY COMMISSION

[Docket Nos. 50-245, 50-336, and 50-423; NRC-2011-0202]


Dominion Nuclear Connecticut, Inc., Millstone Power Station, Unit 
Nos. 1, 2, and 3; Environmental Assessment and Finding of No 
Significant Impact

    The U.S. Nuclear Regulatory Commission (NRC) is considering 
issuance of an exemption from Title 10 of the Code of Federal 
Regulations (10 CFR) Part 26, ``Fitness for Duty Programs,'' for 
Facility Operating License Nos. DPR-21, DPR-65, and NPF-49, issued to 
Dominion Nuclear Connecticut, Inc. (the licensee), for operation of the 
Millstone Power Station Unit Nos. 1, 2, and 3, located in New London 
County, Connecticut. Therefore, as required by 10 CFR 51.21, the NRC 
performed an environmental assessment. Based on the results of the 
environmental assessment, the NRC is issuing a finding of no 
significant impact.

Environmental Assessment

Identification of the Proposed Action

    The proposed action would provide exemption from the work hour 
control requirements of 10 CFR 26.205(c) and (d) during declarations of 
severe weather conditions involving tropical storm or hurricane force 
winds.
    The proposed action is in accordance with the licensee's 
application dated February 10, 2011 (Agencywide Documents Access and 
Management System (ADAMS) Accession No. ML110450583), as supplemented 
by letter dated March 10, 2011 (ADAMS Accession No. ML110740442).

The Need for the Proposed Action

    The proposed action extends the exception provided by 10 CFR 
26.207(d) to include pre-defined entry and exit conditions related to 
hurricane events because the sequestering of plant personnel and 
related staff resource limitations may occur at times prior to and 
following the current entry and exit conditions (i.e., emergency 
declaration) specified in 10 CFR 26.207(d). Entry into a severe weather 
situation involving tropical storm or hurricane force winds can impose 
conditions similar to entry into the site emergency plan where the 
imposition of work hour controls on vital personnel could impede the 
ability to focus on plant safety and security, and may be detrimental 
to the health and safety of the public.

Environmental Impacts of the Proposed Action

    The NRC has completed its environmental assessment of the proposed 
action and concludes that extending the exception provided by 10 CFR 
26.207(d) to include pre-defined entry and exit conditions related to 
hurricane events would not significantly affect plant safety, as it 
does not change the Technical Specification-required shift staffing. 
Additionally, the time from entry into the condition in which the work 
hour control exemption applies, to exiting the condition, is limited to 
severe weather situations involving tropical storm or hurricane force 
winds. The licensee states that the Hurricane Response Plan (Nuclear) 
and other plant-specific procedures ensure that adequate resources and 
guidance are in place to prepare for, respond to, and recover from 
severe weather conditions associated with tropical storm or hurricane 
force winds.
    The proposed action will not significantly increase the probability 
or consequences of accidents. The proposed action would not result in 
an increased radiological hazard beyond those previously analyzed in 
the Final Safety Analysis Report. No changes are being made in the 
types of effluents that may be released offsite. There is no 
significant increase in the amount of any effluent released offsite. 
There is no significant increase in occupational or public radiation 
exposure. No changes will be made to plant buildings or site property. 
Therefore, there are no significant radiological environmental impacts 
associated with the proposed action.

[[Page 54261]]

    The proposed action does not result in changes to land use or water 
use, or result in changes to the quality or quantity of non-
radiological effluents. No changes to the National Pollution Discharge 
Elimination System permits are needed. No effects on the aquatic or 
terrestrial habitat in the vicinity of the plant, or to threatened, 
endangered, or protected species under the Endangered Species Act, or 
impacts to fish habitat covered by the Magnuson-Stevens Act are 
expected. There are no impacts to the air or ambient air quality. There 
are no impacts to historical or cultural resources. There would be no 
noticeable effect on socioeconomic conditions in the region. Therefore, 
no changes or different types of non-radiological environmental impacts 
are expected as a result of the proposed action.
    Accordingly, the NRC concludes that there are no significant 
environmental impacts associated with the proposed action.

Environmental Impacts of the Alternatives to the Proposed Action

    As an alternative to the proposed action, the staff considered 
denial of the proposed action (i.e., the ``no-action'' alternative). 
Denial of the application would result in no change in current 
environmental impacts. Other alternatives to the proposed action 
include entry and exit conditions, other than those proposed by the 
licensee, which would change the duration in which the exemption is 
effective. The staff concludes that these alternatives would not have a 
significant impact. The environmental impacts of the proposed action 
and the alternative actions are similar.

Alternative Use of Resources

    The action does not involve the use of any different resources than 
those previously considered in the U.S. Atomic Energy Commission's 1973 
``Final Environmental Statement Related to the Continuation of 
Construction of Unit 2 and the Operation of Units 1 and 2, Millstone 
Nuclear Power Station,'' the NRC's 1984 ``Final Environmental Statement 
related to operation of Millstone Nuclear Power Station, Unit No. 3,'' 
and NUREG-1437, ``Generic Environmental Impact Statement for License 
Renewal of Nuclear Plants,'' Supplement 22 regarding Millstone Power 
Station, Units 2 and 3.

Agencies and Persons Consulted

    In accordance with its stated policy, on May 13, 2011, the staff 
consulted with the Connecticut State official, Michael Firsick of the 
Department of Environmental Protection, regarding the environmental 
impact of the proposed action. The State official had no comments.

Finding of No Significant Impact

    On the basis of the environmental assessment, the NRC concludes 
that the proposed action will not have a significant effect on the 
quality of the human environment. Accordingly, the NRC has determined 
not to prepare an environmental impact statement for the proposed 
action.
    For further details with respect to the proposed action, see the 
licensee's letter dated February 10, 2011, as supplemented by letter 
dated March 10, 2011. Documents may be examined, and/or copied for a 
fee, at the NRC's Public Document Room (PDR), located at One White
