NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-361 and 50-362; NRC-2010-0101]
Southern California Edison Company, San Onofre Nuclear Generating
Station, Units 2 and 3; 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 Nos. NPF-10, and NPF-15, issued to Southern California Edison
Company (SCE, the licensee), for operation of the San Onofre Nuclear
Generating Station, Units 2 and 3 (SONGS 2 and 3), located in San Diego
County, California. In accordance with 10 CFR 51.21, the NRC prepared
an environmental assessment documenting its finding. The NRC concluded
that the proposed actions will have no significant environmental
impact.
Environmental Assessment
Identification of the Proposed Action
The proposed action would exempt SCE from the required
implementation date of March 31, 2010, for one new requirement of 10
CFR part 73. Specifically, SCE would be granted a second exemption,
further extending the date for full compliance with one new requirement
contained in 10 CFR 73.55, from October 31, 2010 (the date specified in
a prior exemption granted by NRC on March 16, 2010), until February 28,
2011. SCE has proposed an alternate full compliance implementation date
of February 28, 2011, which is approximately 11 months beyond the
compliance 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 reactors, fuel, plant structures, support structures, water, or
land at the SONGS 2 and 3 site.
The proposed action is in accordance with the licensee's
application dated August 24, 2010, as supplemented by letter dated
October 17, 2010. 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 from the regulation, if granted.
The Need for the Proposed Action
The proposed action, a second scheduler exemption, is needed to
provide the licensee with additional time to implement one specific
element of the new requirements in 10 CFR part 73, which involves
significant physical modifications to the SONGS 2 and 3 security
systems. While the licensee completed much of the work required by the
10 CFR Part 73 rule change at SONGS 2 and 3 by the March 31, 2010,
implementation date, and has made substantial progress on completing
the remaining item for which the previous scheduler exemption was
granted, SCE requires additional time to complete all modifications
associated with the single remaining item to achieve full compliance
with 10 CFR part 73.
Environmental Impacts of the Proposed Action
The NRC has completed its environmental assessment of the proposed
action. The staff has concluded that the proposed action to further
extend the implementation deadline for one item would not
[[Page 69137]]
significantly affect plant safety and would not significantly affect
the probability of an accident.
The proposed action would not result in an increased radiological
hazard beyond those hazards 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 or emissions that affect
radiation exposures to plant workers and members of the public.
Therefore, no radiological impacts are expected as a result of the
proposed exemption.
The proposed action is an extension of the compliance deadline and
will not result in any additional construction or major renovation of
any buildings or structures, nor any ground disturbing activities,
beyond the security improvements previously planned to achieve
compliance with the new rule. No changes in the size of the workforce,
or in traffic to or around SONGS 2 and 3, are expected as a result of
an extension of the compliance deadline. Providing the licensee with
additional time to comply with the revised requirements of 10 CFR 73.55
would not alter land use, air quality, and water use (quality and
quantity) conditions or National Pollutant Discharge Elimination System
permits at SONGS 2 and 3. Aquatic and terrestrial habitat in the
vicinity of the plant; threatened, endangered, and protected species
under the Endangered Species Act; and essential fish habitat covered by
the Magnuson-Stevens Act would not be affected. In addition, historic
and cultural resources, socioeconomic conditions, and minority- and
low-income populations in the vicinity of SONGS 2 and 3 would also not
be affected by this action. Therefore, no changes to or different types
of non-radiological environmental impacts are expected as a result of
the proposed exemption.
As previously noted, in promulgating its amendments to 10 CFR part
73, the Commission prepared an environmental assessment of the rule
change and published a finding of no significant impact (10 CFR parts
50, 52, 72, and 73, Power Reactor Security Requirements, March 27,
2009; 74 FR 13926). Thus, through the proposed action, the Commission
would be granting additional time for the licensee to comply with
regulatory requirements for which the Commission has already found no
significant impact.
For the foregoing reasons, the NRC concludes that there would be no
significant radiological or non-radiological environmental impacts
associated with the extension of the implementation date for one
element of the new requirements of 10 CFR 73.55 for SONGS 2 and 3.
Environmental Impacts of the Alternatives to the Proposed Action
As an alternative to the proposed action, the NRC staff considered
denial of the proposed action (i.e., the ``no-action'' alternative).
Denial of the exemption request would result in no change in current
environmental impacts. Denial of the exemption request would result in
the licensee being in non-compliance with 10 CFR 73.55(a)(1) and thus,
subject to NRC enforcement action. The end result, however, would still
be ultimate licensee compliance with the requirements of 10 CFR 73.55,
but with the added expense to both the NRC and the licensee of any
enforcement actions. The NRC concludes that the environmental impacts
of the proposed exemption and the ``no action'' alternative are
similar.
Alternative Use of Resources
The proposed action does not involve the use of any different
resources than those previously considered in the Final Environmental
Statement for SONGS Units 2 and 3, dated May 12, 1981.
Agencies and Persons Consulted
In accordance with its stated policy, on October 22, 2010, the NRC
staff consulted with the California State official, Mr. Stephen Hsu of
the California Department of Public 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 above environmental assessment, which in
accordance with 10 CFR 51.32(a)(4), is incorporated into this finding
of no significant impact by reference, the NRC concludes that the
proposed action constitutes an administrative change (timing) that
would 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 August 24, 2010, as supplemented by letter
dated October 17, 2010. Portions of the August 24 and October 17, 2010,
submittals contain safeguards and security-related information and,
accordingly, redacted versions of those letters are available for
public review in the Agencywide Documents Access and Management System
(ADAMS), at Accession Nos. ML102380401 and ML102920691, respectively.
