NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-275 and 50-323; NRC-2010-0059]
Pacific Gas and Electric Company; Diablo Canyon Power Plant
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. DPR-80 and DPR-82, issued to Pacific Gas and Electric
Company (PG&E, the licensee), for operation of the Diablo Canyon Power
Plant, Unit Nos. 1 and 2 (DCPP), located in San Luis Obispo 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 PG&E from the required
implementation date of March 31, 2010, for several new requirements of
10 CFR Part 73. Specifically, PG&E 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. PG&E has proposed an
alternate full compliance implementation date of June 30, 2011,
approximately 15 months 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 PG&E site.
The proposed action is in accordance with the licensee's
application dated December 4, 2009.
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 PG&E security
system to meet the new requirements in 10 CFR Part 73. Implementation
of the new requirements will involve physical modifications to the
existing plant security system.
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)].
With its request to extend the implementation deadline, the
licensee currently maintains a security system acceptable to the NRC
and that will continue to provide acceptable physical protection of the
DCPP in lieu of the new requirements in 10 CFR Part 73. Therefore, the
extension of the implementation date of the new requirements of 10 CFR
Part 73 to June 30, 2011, would not have any significant environmental
impacts.
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 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 the DCPP,
dated May 1973, with Addendum dated May 1976.
Agencies and Persons Consulted
In accordance with its stated policy, on January 20, 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 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.

related and safeguards information and, accordingly, is being withheld

action, see the redacted version of the December 4, 2009, letter
