SUPPLEMENTARY INFORMATION:
I. Introduction
On September 17, 2010, Exelon Generation submitted an application
(ADAMS Accession No. ML102650247) to the NRC to renew NRC License SNM-
2505 for the Calvert Cliffs ISFSI in Calvert County, Maryland, for a
period of 40 years. Exelon Generation supplemented its application by
submittals dated February 10, 2011, March 9, 2011, June 28, 2011, and
December 15, 2011 (ADAMS Accession Nos. ML110620120, ML110730731,
ML11180A270, and ML11364A024). The NRC staff prepared an EA in
accordance with Sec. 51.30(a) of Title 10 of the Code of Federal
Regulations (10 CFR), publishing a notice of issuance for the EA and a
FONSI in the Federal Register on June 8, 2012 (77 FR 34093).
The NRC's licensing proceedings for nuclear reactors and ISFSIs
have historically relied upon a generic determination codified in the
NRC's regulations (10 CFR Part 51) to satisfy the agency's obligations
under the National Environmental Policy Act of 1969, as amended (NEPA),
with respect to the narrow area of the environmental impacts of storage
of spent nuclear fuel (spent fuel) beyond a reactor's licensed life for
operation and prior to ultimate disposal (continued storage). The Court
of Appeals for the District of Columbia Circuit, in New York v. NRC,
681 F. 3d 471 (D.C. Cir. 2012), vacated the NRC's 2010 update to that
rule (75 FR 81031; December 23, 2010) and remanded it to the NRC.
Thereafter, the Commission determined on August 7, 2012, that the NRC
would not issue licenses dependent upon the formerly known Waste
Confidence Decision and Temporary Storage Rule until the Court of
Appeals' was appropriately addressed (Commission Order CLI-12-16, ADAMS
Accession No. ML12220A199).
On September 19, 2014 (79 FR 56238), the NRC published a final rule
at 10 CFR 51.23, ``Environmental impacts of continued storage of spent
nuclear fuel beyond the licensed life for operations of a reactor''
(RIN 3150-AJ20; NRC-2012-0246). That rule, effective October 20, 2014,
codifies the NRC's generic determinations in NUREG-2157 (ADAMS
Accession Nos. ML14196A105 and ML14196A107) regarding the environmental
impacts of the continued storage of spent fuel. In CLI-14-08 (ADAMS
Accession No. ML14238A213), the Commission held that the revised 10 CFR
51.23 and associated NUREG-2157 cure the deficiencies identified by the
court in New York v. NRC, 681 F.3d 471 (D.C. Cir. 2012) and stated that
the rule satisfies the NRC's NEPA obligations with respect to continued
storage. The rule, however, does not authorize the storage of spent
fuel.
In EAs prepared for future relevant licensing actions related to a
reactor's spent nuclear fuel, 10 CFR 51.23(b) now requires the NRC to
consider the environmental impacts of continued storage, if the impacts
of continued storage of spent fuel are relevant to the proposed action.
An appendix to the re-issued EA (ADAMS Accession No. ML14282A278)
prepared for the proposed renewal of the Calvert Cliffs ISFSI license
provides the NRC staff's consideration of the impact determinations in
NUREG-2157 regarding continued storage.
The NRC staff has also updated its assessment of cumulative impacts
to include new information about reasonably foreseeable future actions
(RFFAs) in the vicinity of or associated with the ISFSI site. These
RFFAs include Exelon Generation's proposed expansion of the ISFSI and
updates to the Cove Point liquefied natural gas
[[Page 63445]]
(LNG) export project in Lusby, Calvert County, Maryland.
The NRC staff also updated the EA to reflect Exelon Generation's
additional supplements to its license renewal application as submitted
by letters dated July 27, 2012, April 24, 2013, and September 18, 2014
(ADAMS Accession Nos. ML12212A216, ML13119A242, ML13119A243,
ML13119A244, and ML14267A065).
II. Summary of the Environmental Assessment
Description of the Proposed Action
Exelon Generation is requesting that NRC License SNM-2505 for the
Calvert Cliffs site-specific ISFSI be renewed for 40 years. Under its
current license, Exelon Generation is authorized to receive, acquire,
and possess the spent fuel from the Calvert Cliffs, Units 1 and 2,
nuclear generating units on the Calvert Cliffs site, and other
radioactive materials associated with spent fuel storage at the ISFSI
located in Calvert County, Maryland, in accordance with the
requirements of 10 CFR Part 72.
Need for the Proposed Action
Exelon Generation is requesting renewal of the ISFSI operating
license to provide the option of continued temporary dry storage of
spent nuclear fuel assemblies generated by operation of Calvert Cliffs,
Units 1 and 2.
Environmental Impacts of the Proposed Action
In its 2012 EA for the Calvert Cliffs ISFSI license renewal, the
NRC staff determined that impacts from the proposed renewal for 40
years would be SMALL and not significant for all environmental resource
areas. This is due to the passive nature of the ISFSI in that it emits
no gaseous or liquid effluents during operation. Also, the ISFSI is
designed to minimize radiological doses to workers and members of the
public. Finally, the ISFSI is located at a distance sufficient from
both the Chesapeake Bay and Maryland State Route 2/4, in wooded,
rolling topography, so as to minimize its impact on air quality, noise
levels, federally-listed threatened and endangered species, and scenic/
visual resources.
In addition, as discussed in the 2012 EA, archaeological
investigations conducted in association with the proposed Calvert
Cliffs Unit 3 project identified previously surveyed, inventoried, and
recorded cultural resources within a 16-kilometer (10-mile) radius of
the existing Calvert Cliffs site. As part of these archeological
investigations, five architectural resources on the Calvert Cliffs site
and one archaeological site were identified as eligible for listing on
the National Register of Historic Places. These sites, however, are
located outside the ISFSI facility footprint and areas of ISFSI
operations. Therefore, the NRC staff concluded in the 2012 EA that the
impacts to historic and cultural resources were not significant.
The NRC staff also evaluated whether cumulative environmental
impacts could result from the incremental impact of the proposed action
when added to the past, present, or reasonably foreseeable future
actions in the area. The NRC staff concluded that the proposed action
would have a SMALL incremental contribution to cumulative impacts on
environmental resources that would not be significant.
Updates From the 2012 Environmental Assessment
The NRC staff has added an appendix to the re-issued EA that
provides the NRC's consideration of the impact determinations in NUREG-
2157 regarding continued storage. The NRC staff's evaluation of the
potential environmental impacts of continued storage of spent fuel
presented in NUREG-2157 identifies an impact level, or a range of
impacts, for each resource area for a range of site conditions and
timeframes. The timeframes analyzed in NUREG-2157 include the short-
term timeframe (60 years beyond the licensed life of a reactor), the
long-term timeframe (an additional 100 years after the short-term
timeframe), and an indefinite timeframe. Taking into account the SMALL
impacts from at-reactor continued storage in the short-term timeframe,
which the NRC considers most likely, the greater uncertainty reflected
in the ranges in the long-term and indefinite timeframes compared to
the greater certainty in the SMALL findings as discussed in NUREG-2157,
and the relative likelihood of the timeframes, the NRC staff finds that
the impact determinations for at-reactor storage from NUREG-2157 do not
change the NRC staff's evaluation of the potential environmental
impacts from the proposed renewal of the Calvert Cliffs site-specific
ISFSI license.
Additionally, the NRC staff has updated the cumulative impacts
analysis in the re-issued EA to reflect new information about (1) the
Federal Energy Regulatory Commission's (FERC's) authorization of the
Dominion Cove Point LNG, LP proposal to construct and operate
facilities to liquefy and export domestically produced natural gas from
its existing liquefied natural gas import terminal located in Lusby,
Maryland; and (2) Exelon Generation's license amendment request to
change the Calvert Cliffs ISFSI Technical Specifications to allow the
storage of approved Westinghouse and AREVA Combustion Engineering 14x14
fuel designs in the Nutech Horizontal Modular Storage (NUHOMS)-32PHB
dry shielded canister and expand the Calvert Cliffs ISFSI's capacity to
continue to support operation of the Calvert Cliffs, Units 1 and 2,
through the end of the currently licensed life of the plant.
The FERC performed a cumulative impacts analysis from the
construction and operation of the proposed Dominion Cove Point LNG, LP
project as part of its NEPA environmental review. In its EA, FERC
concluded that the proposed project, in association with other projects
in the area, would not result in significant cumulative impacts.
For the purposes of the cumulative impacts analysis in the re-
issued EA, the NRC staff expects that the construction activities
associated with the proposed expansion of the Calvert Cliffs ISFSI
would continue to occur on an as-needed basis. Therefore, although
construction activities associated with the expansion of the ISFSI
could overlap with the construction activities for the other projects
discussed in the cumulative impact analysis, construction of the
horizontal storage modules would be staggered and only conducted when
more storage is needed. Therefore, potential environmental impacts from
the construction of the additional horizontal storage modules would not
all be experienced at the same time. In addition, operation of the
ISFSI with an increased capacity is required to be conducted in a
manner that meets occupational and public annual radiological dose
regulatory limits in 10 CFR Parts 20 and 72. The NRC staff determined
in the 2012 EA that the proposed ISFSI license renewal would not have a
significant impact on environmental resources. Therefore, the NRC staff
concluded that the proposed action would not have a significant
incremental contribution to cumulative impacts.
Environmental Impacts of the Alternatives to the Proposed Action
In the 2012 EA, the NRC staff evaluated two alternatives to the
proposed action: (1) The no-action alternative, and (2) renewing the
ISFSI license for 20 years. The NRC staff concluded that the potential
impacts
[[Page 63446]]
from these two alternatives did not differ significantly from the
impacts associated with the proposed action, and the NRC staff has
determined that the information in this update does not change that
conclusion.
Agencies and Persons Consulted
In preparing the 2012 EA, the NRC staff consulted with other
agencies regarding the proposed action. These consultations are
intended to (1) ensure that the requirements of Section 7 of the
Endangered Species Act (ESA) and Section 106 of the National Historic
Preservation Act (NHPA) are met; (2) fulfill the NRC's requirements in
meeting the provisions of Section 307 of the Coastal Zone Management
Act of 1972, as amended; and (3) provide the designated state liaison
agencies the opportunity to comment on the proposed action.
Based on that consultation, none of the agencies identified
concerns with the proposed action. Because the proposed action is
unchanged from the 2012 EA and consultation, the NRC staff has not
reinitiated consultation with these agencies and persons for this
update.
III. Finding of No Significant Impact
After considering the impacts from continued storage presented in
NUREG-2157 and the updated information concerning reasonably
foreseeable future actions, the NRC staff concludes that these do not
change the NRC staff's finding of no significant impact for the
proposed renewal for Exelon Generation's Calvert Cliffs ISFSI license,
as published. Therefore, preparation of an Environmental Impact
Statement is not warranted.
