NUCLEAR REGULATORY COMMISSION
Federal Emergency Management Agency
[Docket 30-7130]
Issuance of Environmental Assessment and Finding of No
Significant Impact Regarding the Proposed Transportation Exemption
The U.S. Nuclear Regulatory Commission (NRC or Commission) is
considering issuance of a one-time exemption, pursuant to 10 CFR 71.8,
from the provisions of 10 CFR 71.73(c)(1) and (3) to the Federal
Emergency Management Agency (FEMA). The requested exemption would allow
FEMA to transport ten CDV-794 calibrators containing up to 85 curies of
cesium-137 in packages that otherwise meet the performance requirements
for a Type B transportation package pursuant to 10 CFR part 71 as
exempted. Nine calibrators will be shipped to a central location so
that disassembly of the calibrators and disposal of the
[[Page 20488]]
radioactive material can be done in a controlled environment to reduce
worker radiation exposures. The tenth calibrator will be shipped 25
miles within the State of Hawaii, to another NRC licensee for use under
its radiation protection program.
An NRC categorical exclusion for package approvals in 10 CFR
51.22(c)(13) does not apply to packaging authorized under an exemption.
Consequently, an environmental assessment of the proposed exemption was
prepared. The Department of Transportation (DOT) has already issued an
exemption from DOT regulations for the proposed calibrator shipments.
Environmental Assessment (EA)
Identification of Proposed Action: By letter dated July 21, 1999,
FEMA requested a package approval for the transport of ten CDV-794
calibrators by means of an exemption from the requirements of 10 CFR
71.71(c)(1) and (3). On December 19, 2000, FEMA submitted a Safety
Analysis and Environmental Report (SA/ER) in support of its application
for an exemption. While each calibrator may contain up to 130 curies of
cesium-137, FEMA has indicated that the cesium sources are currently at
an activity level of about 85 curies. FEMA also proposed compensatory
safety measures to support the request for this exemption.
Each calibrator will contain a radioactive source that is designed
to meet the special form requirements of 10 CFR 71.75. The source is
contained in a tungsten alloy source holder which is bolted and sealed
into the primary depleted uranium (DU) shield. The DU shield is bolted
to an aluminum-lined steel calibration chamber. This entire assembly is
then bolted in a rectangular steel cabinet mounted on a tubular steel
stand. The cabinet has two hinged metal covers that allow the
calibrator to be locked to prevent unauthorized access. The calibrator
is then placed into a custom-design wooden overpack for shipment.
FEMA plans to dispose of nine cesium-137 sources contained in the
CDV-794 calibrators by transfer to another licensee. To accomplish this
task, nine CDV-794 calibrators will need to be transported from their
present location to FEMA's Mount Weather Emergency Assistance Center in
Berryville, Virginia; the tenth CDV-794 calibrator will be transferred
for use at a U.S. Army facility in Hawaii. FEMA has contracted with the
U.S. Army Communication-Electronic Command (CECOM) radiological
specialists to supervise and conduct the required shipments. CECOM will
travel to each of the ten sites and conduct contamination surveys and
prepare the calibrators for shipment in accordance with FEMA's written
procedures. CECOM will ship the calibrators in exclusive-use vehicles
and accompany each shipment to its final destination. Upon arrival at
FEMA's Mount Weather Emergency Assistance Center, CECOM will conduct
physical inspection and contamination surveys. Other properly licensed
personnel will then remove the cesium sources, consolidate them into
NRC-certified transportation packages and ship them to a contractor's
facility in California. Once the cesium sources are removed, CECOM will
remove the depleted uranium shields and coordinate final disposition of
all remaining calibrator components. FEMA estimates the transport and
disposal project will end in 2002, pending the appropriation of
sufficient funds for the activity.
Section 71.73(c)(1) and (3) concern tests for hypothetical accident
conditions and require: (1) ``A free drop of the specimen through a
distance of 9 m (30 feet) onto a flat, essentially unyielding,
horizontal surface, striking the surface in a position for which
maximum damage is expected.'', and (2) ``A free drop of the specimen
through a distance of 1 m (40 in) in a position for which maximum
damage is expected, onto the upper end of a solid, vertical,
cylindrical, mild steel bar mounted on an essentially unyielding,
horizontal surface. The bar must be 15 cm (6 in) in diameter, with the
top horizontal and its edge rounded to a radius of not more than 6 mm
(0.25 in), and of a length as to cause maximum damage to the package,
but not less than 20 cm (8 in) long. The long axis of the bar must be
vertical.'' FEMA determined that the calibrator would not survive a 30-
foot drop test because the bolts holding the source shield to the
calibrator cabinet would fail. FEMA stated that the calibrator could
withstand an accidental 10-foot drop. FEMA also stated that the package
meets the other tests for hypothetical accident conditions except for
the 1 meter puncture test. FEMA further proposed compensatory safety
measures to provide an adequate level of safety during the shipments.
By exempting FEMA from the hypothetical accident free drop and
puncture tests in 10 CFR 71.73 the NRC will be able to approve the
package for the shipment of nine calibrators to a central facility and
one calibrator to another licensee under the general license in 10 CFR
71.12(a). The proposed action before the Commission is whether to grant
these exemptions under 10 CFR 71.8 and approve the package for the one-
time transport of these calibrators.
On December 19, 2000, FEMA submitted a SA/ER to NRC to address the
proposed shipment of calibrators that does not meet the performance
requirements of 10 CFR part 71. FEMA provided additional information on
February 13, and March 9, 2001, in response to the NRC staff's
requests. The NRC staff has reviewed the application and has determined
that authorizing the one-time shipment of each of the ten calibrators,
with compensatory safety measures, would not be inimical to public
health and safety.
Need for the Proposed Action: FEMA is seeking the exemption to
consolidate and properly dispose of calibrators containing a
radioactive source to assure adequate protection of public health and
safety of FEMA-owned calibrators currently in the possession of state
organizations that no longer need, and do not want, to retain the
calibrators. FEMA's termination of its Radiological Defense Program and
state funding lead to the termination of state Radiological Defense
Programs. Some states have requested removal of the FEMA-owned
calibrators as quickly as possible because of state funding shortfalls
and related difficulties in meeting licensing requirements. FEMA is
concerned that persons in possession of the calibrators under the state
emergency programs may not have sufficient resources to properly
oversee the safety control of the material since FEMA stopped funding
these programs. FEMA's Congressional funding does not allow for the
development of a Type B package to make the relocations and the time
constraints do not allow the use of an authorized package to make the
shipments. Further, the state locations at which these units are in
storage are not properly constructed to safely allow the removal and
the proper packaging of the sources for shipment at the field location.
Environmental Impacts of the Proposed Action: The potential
environmental impact of transporting radioactive material pursuant to
10 CFR part 71 was initially presented in the ``Final Environmental
Statement on the Transportation of Radioactive Material by Air and
Other Modes'' for the Proposed Rule to amend 10 CFR part 71 (40 FR
23768 (1977)). The environmental statement was published in 1977 as
NUREG-0170, Volumes 1 and 2.
The calibrators were originally manufactured by Technical
Operations Inc. The manufacturer certified the calibrators to meet the
requirements of DOT Specification 55 containers, which
[[Page 20489]]
was approved for use under NRC part 71 general license provisions.
Hypothetical accident condition testing was not part of the
requirements at the time this package was certified by the user. FEMA
has acknowledged that the package would not survive hypothetical
accident conditions that involved more than a 10 foot drop or a
puncture of the package and that a radiological release could occur and
has proposed compensatory safety measures that will provide an adequate
level of safety consistent with the requirements of 10 CFR 71.8 by
providing effective response to such a postulated accident. These
compensatory measures include: (1) Pre and post-packing inspection for
radiation hazard and proper packaging, (2) use of an exclusive use
vehicle, (3) persons trained in radiation protection escorting the
exclusive use vehicle, and (4) operational controls and procedures that
would minimize accident risk and would ensure public safety in the
event of a transportation accident. The NRC staff concluded by
evaluation that the operations and administrative controls proposed by
FEMA for the shipment provide reasonable assurance that any radiation
exposure to the public or workers will not exceed regulatory limits in
the event of an accident during shipment because of the quick response
to such an event. Additionally, FEMA has selected transportation routes
that will limit the road mileage traveled, further reducing the
likelihood of an accident.
The staff concurs with FEMA's safety evaluation of the proposed
exemption request and finds that FEMA's planned compensatory measures
ensure that use of the package in accordance with the exemption
requested does not pose a significant increased risk to public health
and safety. Furthermore, the proposed action now under consideration
would not change the potential environmental effects assessed in the 10
CFR part 71 rulemaking (40 FR 23768 (1977)).
Therefore, the staff has determined that there will be no
significant environmental impacts as a result of approving the
exemption for the one-time shipment of the specified calibrators.
Alternatives to the Proposed Action: The staff evaluated an
alternative involving removal of the radioactive source at each site
and found that this alternative produced a greater occupational
exposure (200 mrem versus 20 mrem if shipped under the exemption), and
an increased potential for radiation exposure to members of the public.
Both of these results are not consistent with the NRC's as low as
reasonably achievable (ALARA) concept, and this alternative would also
result in increased handling and storage costs. Another alternative to
the proposed action would be to require the state to continue to
possess and store these calibrators until such time as FEMA can procure
funding to design, test, and obtain NRC approval, and construct a
transportation package that meets all 10 CFR part 71 requirements. This
alternative would increase the likelihood of loss of control of
material currently in the hands of state licensees which have lost
Federal funding for their radiation protection programs. As such, both
of the alternatives are less desirable than the proposed action.
Agencies and Persons Consulted: Officials from the DOT Office of
Hazardous Materials Technology, and the Bureau of Radiological Health,
Virginia Department of Health, were contacted about the EA for the
proposed action and had no concerns.
Finding of No Significant Impact
The environmental impacts of the proposed action have been reviewed
in accordance with the requirements set forth in 10 CFR part 51. Based
upon the foregoing EA, the Commission finds that the proposed action of
approving a package with an exemption from 10 CFR 71.73(c)(1) and (3)
so that FEMA may transport ten calibrators containing cesium-137 will
not significantly impact the quality of the human environment.
Accordingly, the Commission has determined not to prepare an
environmental impact statement for the proposed exemption.

FEMA exemption request dated July 21, 1999, and FEMA's Safety Analysis
and Environmental Report dated December 19, 2000, as supplemented
