NUCLEAR REGULATORY COMMISSION

 [Docket No. 50-416; NRC-2010-0082]


Entergy Operations, Inc.; Grand Gulf Nuclear Station, Unit 1; 
Environmental Assessment and Finding of No Significant Impact

    The U.S. Nuclear Regulatory Commission (NRC) is considering 
issuance of an exemption, pursuant to Title 10 of the Code of Federal 
Regulations (10 CFR) section 73.5, ``Specific exemptions,'' from the 
implementation date for certain new requirements of 10 CFR part 73, 
``Physical protection of plants and materials,'' for Facility Operating 
License No. DPR-46, issued to Entergy Operations, Inc. (Entergy, the 
licensee), for operation of the Grand Gulf Nuclear Station, Unit 1 
(GGNS), located in Claiborne County, Mississippi. 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 exempt Entergy from the required 
implementation date of March 31, 2010, for several new requirements of 
10 CFR part 73. Specifically, Entergy would be granted an exemption 
from being in full compliance with certain new requirements contained 
in 10 CFR 73.55 by the March 31, 2010, deadline. Entergy has proposed 
an alternate full compliance implementation date of March 31, 2011, 1 
year beyond the date required by 10 CFR part 73. The proposed action, 
an extension of the schedule for completion of certain actions required 
by the revised 10 CFR part 73, does not involve any physical changes to 
the reactor, fuel, plant structures, support structures, water, or land 
at the Entergy site.
    The proposed action is in accordance with the licensee's 
application dated January 14, 2010, as supplemented by letters dated 
January 18 and February 4, 2010.

The Need for the Proposed Action

    The proposed action is needed to provide the licensee with 
additional time to perform the required upgrades to the Entergy 
security system due to resource and logistical impacts of the spring 
2010 refueling outage and other factors, such as limited vendor 
resources.

Environmental Impacts of the Proposed Action

    The NRC has completed its environmental assessment of the proposed 
exemption. The staff has concluded that the proposed action to extend 
the implementation deadline would not significantly affect plant safety 
and would not have a significant adverse effect on the probability of 
an accident occurring.
    The proposed action would not result in an increased radiological 
hazard beyond those previously analyzed in the environmental assessment 
and finding of no significant impact made by the Commission in 
promulgating its revisions to 10 CFR part 73 as discussed in a Federal 
Register notice dated March 27, 2009 (74 FR 13926). There will be no 
change to radioactive effluents that affect radiation exposures to 
plant workers and members of the public. Therefore, no changes or 
different types of radiological impacts are expected as a result of the 
proposed exemption.
    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 permit 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 essential fish habitat covered by the Magnuson-Steven's Act 
are expected. There are no impacts to the air or ambient air quality.
    There are no impacts to historical and cultural resources. There 
would be no impact to socioeconomic resources. Therefore, no changes to 
or different types of non-radiological environmental impacts are 
expected as a result of the proposed exemption.
    Accordingly, the NRC concludes that there are no significant 
environmental impacts associated with the proposed action. In addition, 
in promulgating its revisions to 10 CFR part 73, the Commission 
prepared an environmental assessment and published a finding of no 
significant impact [Part 73, Power Reactor Security Requirements, 74 FR 
13926 (March 27, 2009)].
    The NRC staff's safety evaluation will be provided in the exemption 
that will be issued as part of the letter to the licensee approving the 
exemption to the regulation, if granted.

Environmental Impacts of the Alternatives to the Proposed Action

    As an alternative to the proposed actions, the NRC staff considered 
denial

[[Page 9956]]

of the proposed action (i.e., the ``no-action'' alternative). Denial of 
the exemption request would result in no change in current 
environmental impacts. If the proposed action was denied, the licensee 
would have to comply with the March 31, 2010, implementation deadline. 
The environmental impacts of the proposed exemption and the ``no-
action'' alternative are similar.

Alternative Use of Resources

    The action does not involve the use of any different resources than 
those considered in the Final Environmental Statement for GGNS dated 
September 1981.

Agencies and Persons Consulted

    In accordance with its stated policy, on January 19, 2010, the NRC 
staff consulted with the Mississippi State official, Mr. B. Smith of 
the Division of Radiological Health, 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 January 14, 2010, as supplemented by letters 
dated January 18 and February 4, 2010. Portions of the January 14 and 
February 4, 2010, documents contain security-related information and, 
accordingly, are not available to the public. A redacted version of the 
licensee's January 14, 2010, exemption request is provided in the 
licensee's letter dated January 18, 2010. Other parts of the document 
may be examined, and/or copied for a fee, at the NRC's Public Document 
Room (PDR), located at One White Flint North, Public File Area O-1F21,

available records will be accessible electronically from the Agencywide 
Documents Access and Management System (ADAMS) Public Electronic 
Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/reading-rm/adams.html. Persons who do not have access to ADAMS or who

    Dated at Rockville, Maryland, this 25th day of February 2010.

    For the Nuclear Regulatory Commission.

Operating Reactor Licensing, Office of Nuclear Reactor Regulation.
