NUCLEAR REGULATORY COMMISSION
[Docket Nos. 50-206, 50-361, 50-362, and 72-41; NRC-2015-0093]
Southern California Edison Company San Onofre Nuclear Generating
Station, Units 1, 2, and 3, and Independent Spent Fuel Storage
Installation
AGENCY: Nuclear Regulatory Commission.
ACTION: Environmental assessment and finding of no significant impact;
issuance.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is considering
issuance of exemptions in response to a request from Southern
California Edison Company (SCE or the licensee) that would permit the
licensee to reduce its emergency planning (EP) activities at the San
Onofre Nuclear Generating Station (SONGS), Units 1, 2, and 3, and the
Independent Spent Fuel Storage Installation (ISFSI). The licensee is
seeking exemptions that would eliminate the requirements to maintain
offsite radiological emergency plans and reduce some of the onsite EP
activities based on the reduced risks at the permanently shutdown and
defueled reactors. Offsite emergency planning provisions would still
exist using a comprehensive emergency management
[[Page 21272]]
plan (CEMP) process. The NRC staff is issuing a final Environmental
Assessment (EA) and final Finding of No Significant Impact (FONSI)
associated with the proposed exemptions.
DATES: The EA and FONSI referenced in this document are available on
April 17, 2015.

SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is considering issuance of an exemption concerning Facility
Operating License Nos. DPR-13, NPF-10, and NFP-15, issued to SCE for
the operation of SONGS, Units 1, 2, and 3, respectively, located in San
Diego County, California. Therefore, as required by sections 51.20(b)
and 51.22(c) of Title 10 of the Code of Federal Regulations (10 CFR),
the NRC performed an EA. Based on the results of the EA that follows,
the NRC has determined not to prepare an environmental impact statement
for the exemptions, and is issuing a finding of no significant impact.
SONGS, Units 1, 2, and 3, are permanently shutdown and defueled
power reactors in the process of decommissioning. SONGS is located in
San Diego County, California, on the coast of the Pacific Ocean,
approximately 51 miles north of San Diego, California. SCE is the
holder of Facility Operating License Nos. DPR-13, NPF-10, and NFP-15
for SONGS, Units 1, 2, and 3, respectively. SONGS, Unit 1 was
permanently shut down in 1993. On June 12, 2013, the licensee provided
the certifications that SONGS, Units 2 and 3, had permanently ceased
power operations. On June 28 and July 22, 2013, the licensee provided
certifications that all fuel had been permanently removed from the
SONGS, Units 3 and 2, reactors, respectively. As a permanently shutdown
and defueled facility, and pursuant to 10 CFR 50.82(a)(2), SONGS is no
longer authorized to operate the reactors or emplace fuel into the
reactor vessels, but is still authorized to possess and store
irradiated nuclear fuel. Irradiated fuel is currently stored onsite at
SONGS in spent fuel pools (SFPs) and in the ISFSI dry casks. The
licensee has requested exemptions from certain EP requirements in 10
CFR part 50, ``Domestic Licensing of Production and Utilization
Facilities,'' for SONGS, Units 1, 2, and 3, and the ISFSI. The NRC's
regulations concerning EP do not recognize the reduced risks after a
reactor is permanently shut down and defueled. A permanently shutdown
reactor must continue to maintain the same EP requirements as an
operating reactor. To establish a level of EP commensurate with the
reduced risks, SCE requires exemptions from certain EP regulatory
requirements before it can change its emergency plans.
The NRC is considering issuance of exemptions to SCE from portions
of 10 CFR 50.47, ``Emergency plans,'' and 10 CFR part 50, appendix E,
``Emergency Planning and Preparedness for Production and Utilization
Facilities,'' which would permit SCE to modify its emergency plan to
eliminate the requirements to maintain offsite radiological emergency
plans and reduce some of the onsite EP activities based on the reduced
risks at SONGS, due to its permanently shutdown and defueled status.
Consistent with 10 CFR 51.21, the NRC staff has reviewed the
requirements in 10 CFR 51.20(b) and 10 CFR 51.22(c) and determined that
an EA is the appropriate form of environmental review for the requested
action. Based on the results of the EA, which is provided in Section II
of this document, the NRC is issuing a final finding of no significant
impact.
II. Environmental Assessment
Description of the Proposed Action
The proposed action would exempt SCE from meeting certain
requirements set forth in 10 CFR 50.47 and appendix E to 10 CFR part
50. More specifically, SCE requested exemptions from (1) certain
requirements in 10 CFR 50.47(b) regarding onsite and offsite emergency
response plans for nuclear power reactors, (2) certain requirements in
10 CFR 50.47(c)(2) to establish plume exposure and ingestion pathway EP
zones for nuclear power reactors, and (3) certain requirements in 10
CFR part 50, appendix E, section IV, which establishes the elements
that make up the content of emergency plans. The proposed action,
granting these exemptions, would result in the elimination of the
requirements for the licensee to maintain offsite radiological
emergency plans and reduce some of the onsite EP activities at SONGS,
based on the reduced risks at the permanently shutdown and defueled
reactors. However, requirements for certain onsite capabilities to
communicate and coordinate with offsite response authorities will be
retained. If necessary, offsite protective actions could still be
implemented using a CEMP process. A CEMP in this context, also referred
to as an emergency operations plan (EOP), is addressed in the Federal
Emergency Management Agency's (FEMA) Comprehensive Preparedness Guide
(CPG) 101, ``Developing and Maintaining Emergency Operations Plans.''
CPG 101 is the foundation for State, territorial, Tribal, and local EP
in the United States. It promotes a common understanding of the
fundamentals of risk-informed planning and decisionmaking, and helps
planners at all levels of government in their efforts to develop and
maintain viable, all-hazards, all-threats emergency plans. An EOP is
flexible enough for use in all emergencies. It describes how people and
property will be protected; provides details regarding who is
responsible for carrying out specific actions; identifies the
personnel, equipment, facilities, supplies and other resources
available; and outlines how all actions will be coordinated. A CEMP is
often referred to as a synonym for ``all-hazards planning.''
The proposed action is in accordance with the licensee's
application dated
[[Page 21273]]
March 31, 2014, as supplemented by letters dated September 9, October
2, October 7, October 27, November 3, and December 15, 2014. An
additional supplemental letter dated October 6, 2014, contains
security-related information and is therefore, withheld from public
disclosure.
Need for the Proposed Action
The proposed action is needed for SCE to revise the SONGS emergency
plan to reflect the permanently shutdown and defueled status of the
facility. The EP requirements currently applicable to SONGS are for
operating power reactors. There are no explicit regulatory provisions
distinguishing EP requirements for a power reactor that has been shut
down from those for an operating power reactor. Therefore, since the 10
CFR part 50 licenses for SONGS no longer authorize operation of the
reactors or emplacement or retention of fuel into the reactor vessels,
as specified in 10 CFR 50.82(a)(2), the occurrence of postulated
accidents associated with reactor operation is no longer credible. In
its exemption request, the licensee identified the remaining possible
accidents at SONGS in its permanently shutdown and defueled condition.
The NRC staff evaluated these possible radiological accidents in the
Commission Paper (SECY)-14-0144, dated December 17, 2014. In SECY-14-
0144, the staff verified that SCE's analyses and calculations provide
reasonable assurance that if the requested exemptions were granted,
then (1) for a design-basis accident (DBA), an offsite radiological
release will not exceed the Environmental Protection Agency's (EPA)
Protective Action Guides (PAGs) at the exclusion area boundary, as
detailed in the EPA ``PAG Manual, Protective Action Guides and Planning
Guidance for Radiological Incidents,'' dated March 2013, which was
issued as Draft for Interim Use and Public Comment; and (2) in the
unlikely event of a beyond DBA resulting in a loss of all SFP cooling,
there is sufficient time to initiate appropriate mitigating actions,
and in the unlikely event that a release is projected to occur, there
is sufficient time for offsite agencies to take protective actions
using a CEMP to protect the health and safety of the public. The
Commission approved the NRC staff's recommendation to grant the
exemptions in the Staff Requirements Memorandum to SECY-14-0144, dated
March 2, 2015.
Based on these analyses, the licensee states that application of
all of the standards and requirements of 10 CFR 50.47(b), 10 CFR
50.47(c), and 10 CFR part 50 appendix E, section IV, are not necessary
to achieve the underlying purpose of those rules. SCE also states that
it would incur undue costs in the maintenance of an emergency response
organization in excess of that actually needed to respond to the
diminished scope of credible accidents associated with a shutdown
plant.
Environmental Impacts of the Proposed Action
The NRC staff concluded that the exemptions, if granted, will not
significantly increase the probability or consequences of accidents at
SONGS in its permanently shutdown and defueled condition. There will be
no significant change in the types of effluents that may be released
offsite. There will be no significant increase in the amounts of any
effluents that may be released offsite. There will be no significant
increase in the individual or cumulative occupational or public
radiation exposure. Therefore, there are no significant radiological
environmental impacts associated with the proposed action.
With regard to potential non-radiological impacts, the proposed
action does not have any foreseeable impacts to land, air, or water
resources, including impacts to biota. In addition, there are also no
known socioeconomic or environmental justice impacts associated with
the proposed action. Therefore, there are no significant non-
radiological environmental impacts associated with the proposed action.
Accordingly, the NRC staff 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 NRC 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. The environmental impacts of the proposed action
and the alternative action 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 April 1981, and the ``Final
Generic Environmental Impact Statement on Decommissioning of Nuclear
Facilities,'' NUREG-0586, Supplement 1, dated November 2002.
Agencies or Persons Consulted
The NRC staff did not enter into consultation with any other
Federal agency or with the State of California regarding the
environmental impact of the proposed action. On April 8, 2015, the
California State representatives were notified of this EA and FONSI.
III. Finding of No Significant Impact
The licensee has proposed exemptions from (1) certain requirements
in 10 CFR 50.47(b) regarding onsite and offsite emergency response
plans for nuclear power reactors; (2) certain requirements in 10 CFR
50.47(c)(2) to establish plume exposure and ingestion pathway EP zones
for nuclear power reactors; and (3) certain requirements in 10 CFR part
50, appendix E, section IV, which establishes the elements that make up
the content of emergency plans. The proposed action of granting these
exemptions would result in the elimination of the requirements for the
licensee to maintain offsite radiological emergency plans and reduce
some of the onsite EP activities at SONGS, based on the reduced risks
at the permanently shutdown and defueled reactor. However, requirements
for certain onsite capabilities to communicate and coordinate with
offsite response authorities will be retained.
The NRC staff decided not to prepare an environmental impact
statement for the proposed action. On the basis of the EA included in
Section II of this document, the NRC staff concludes that the proposed
action will not have a significant effect on the quality of the human
environment. Accordingly, the NRC staff has determined that a finding
of no significant impact is appropriate.
