SUPPLEMENTARY INFORMATION:

I. Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is considering the 
issuance of a license amendment to Source Materials License No. STC-
133. This license is held by Defense Logistics Agency (the Licensee), 
for its Curtis Bay Depot (the Facility), located at 710 Ordnance Road 
in Baltimore, Maryland. Issuance of the amendment would incorporate the 
Decommissioning Plan (DP) into the license to allow completion of 
decommissioning activities at the site and eventual unrestricted 
release of the Facility. The NRC has evaluated and approved the 
Licensee's DP. The findings of this evaluation are documented in a 
Safety Evaluation Report, which will be issued along with the 
amendment. The Licensee requested this action in a letter dated 
September 29, 2006. The Licensee's amendment request was noted in the 
Federal Register on February 1, 2007 (72 FR 4734). This Federal 
Register notice also provided an opportunity for a hearing on this 
licensing action. No hearing requests were received. The NRC has 
prepared an Environmental Assessment (EA) in support of this proposed 
action in accordance with the requirements of Title 10, Code of Federal 
Regulations (CFR), Part 51 (10 CFR Part 51). Based on the EA, the NRC 
has concluded that a Finding of No Significant Impact (FONSI) is 
appropriate with respect to the proposed action. The amendment will be 
issued to the Licensee following the publication of this FONSI and EA 
in the Federal Register.

II. Environmental Assessment

Identification of Proposed Action

    The proposed action would approve the Licensee's September 29, 
2006, license amendment request to incorporate the DP into the license, 
resulting in final decommissioning of the Facility and subsequent 
release of the Facility for unrestricted use. License No. STC-133 was 
issued on February 14, 1957, pursuant to 10 CFR Part 40, and has been 
amended periodically since that time. This license authorized the 
Licensee to possess natural uranium and thorium mixtures as ores, 
concentrates and solids for the purpose of storage, sampling, 
repackaging, and transfer for the activities of the National Defense 
Stockpile.
    The Facility is situated on approximately 483 acres of grassy open 
areas and some lightly wooded areas and consists of various building 
pads, buildings and warehouses, some functional and others in a serious 
state of disrepair. A number of paved and dirt roads, along with 
railroad tracks, traverse the site. The Facility is located in an 
industrial area. Within the Facility, use of licensed materials was 
confined to buildings 1022, A-921, B-911, B-912, B-913, F-731, F-734, 
F-735, F-736, F-737, G-721, H-711, H-712, H-713, H-714, H-715, and the 
waste burial pit. Licensed activities ceased in May 2005.

Need for the Proposed Action

    The proposed action is to approve the DP so that the Licensee may 
complete Facility decommissioning activities. Completion of the 
decommissioning activities will reduce residual radioactivity at the 
Facility. NRC regulations require licensees to begin timely 
decommissioning of their sites, or any separate buildings that contain 
residual radioactivity, upon cessation of licensed activities, in 
accordance with 10 CFR 40.42(d). The proposed licensing action will 
support such a goal. NRC is fulfilling its responsibilities under the 
Atomic Energy Act to make a decision on a proposed license amendment 
for decommissioning that ensures protection of the public health and 
safety.

Environmental Impacts of the Proposed Action

    The historical review of licensed activities conducted at the 
Facility shows that such activities involved the storage, repackaging 
and transfer of licensed material in the form of thorium nitrate, 
monazite sand, and sodium sulfate. The licensed materials were always 
stored inside buildings, but were moved to other buildings which 
resulted in some licensed materials being spilled outdoors.
    The NRC staff has reviewed the Licensee amendment request for the 
Facility and examined the impacts of this license amendment request. 
Potential impacts include water resource impact (e.g., water may be 
used for dust control), air quality impacts from dust emissions, 
temporary local traffic impacts resulting from transporting debris, 
human health impacts, noise impacts from equipment operation, scenic 
quality impacts, and waste management impacts.
    Based on its review, the staff has determined that no surface water 
or ground water impacts are expected from the decommissioning 
activities. Additionally, the staff has determined that significant air 
quality, noise, land use, and off-site radiation exposure impacts are 
also not expected. No significant air quality impacts are anticipated 
because of the contamination controls that will be implemented by the 
Licensee during decommissioning activities. In addition, the 
environmental impacts associated with the decommissioning activities 
are bounded by impacts evaluated by NUREG-0586, ``Final Generic 
Environmental Impact Statement on the Decommissioning of Nuclear 
Facilities,'' (GEIS). Generic impacts for this type of decommissioning 
process were previously evaluated and described in the GEIS, which 
concludes that the environmental consequences are small. The risk to 
human health from the transportation of all radioactive material in the 
U.S. was evaluated in NUREG-0170, ``Final Environmental Statement on 
the Transportation of Radioactive Materials by Air and Other Modes.'' 
The principal radiological environmental impact during normal 
transportation is direct radiation exposure to nearby persons from 
radioactive material in the package. The average annual individual dose 
from all radioactive material transportation in the U.S. was calculated 
to be approximately 0.5 millirem, well below the 10 CFR 20.1301 limit 
of 100 millirem for a member of the public. Additionally, the Licensee 
estimates that approximately 200 cubic meters of low-contaminated 
demolition material waste and 930 cubic meters of low-contaminated 
soil, mostly from the excavation of the burial pit, will leave the site 
over the course of the decommissioning project. The waste will be 
transported from the

[[Page 34487]]

Facility by rail car to its final destination. This proposed action 
will not significantly increase the probability or consequences of 
accidents, no changes are being made in the types of any effluents that 
may be released off site, and there is no significant increase in 
occupational or public radiation exposure. Thus, waste management and 
transportation impacts from the decommissioning will not be 
significant.
    Occupational health was also considered in the ``Final 
Environmental Impact Statement on the Transportation of Radioactive 
Material by Air and Other Modes.'' Shipment of these materials would 
not affect the assessment of environmental impacts or the conclusions 
in the ``Final Environmental Impact Statement on the Transportation of 
Radioactive Material by Air and Other Modes.''
    The Staff also finds that the proposed license amendment will meet 
the radiological criteria for unrestricted release as specified in 10 
CFR 20.1402. The Licensee demonstrated this through the development of 
derived concentration guideline limits (DCGLs) for its Facility. The 
Licensee conducted site-specific dose modeling using parameters 
specific to the Facility that adequately bounded the potential dose. 
This included dose modeling for two scenarios: building surfaces and 
soil. The building surface dose model was based on the warehouse worker 
scenario and the soil dose modeling was based on a resident farmer 
scenario.
    The Licensee will maintain an appropriate level of radiation 
protection staff, procedures, and capabilities, and, through its 
Radiation Safety Officer, will implement an acceptable program to keep 
exposure to radioactive materials as low as reasonably achievable 
(ALARA). Work activities are not anticipated to result in radiation 
exposures to the public in excess of ten percent of the 10 CFR 20.1301 
limits.
    The NRC also evaluated whether cumulative environmental impacts 
could result from an incremental impact of the proposed action when 
added to other past, present, or reasonably foreseeable future actions 
in the area. The proposed NRC approval of the license amendment 
request, when combined with known effects on resource areas at the 
site, including further site remediation, are not anticipated to result 
in any cumulative impacts at the site.

Environmental Impacts of the Alternatives to the Proposed Action

    The only alternative to the proposed action of decommissioning the 
Facility is the no-action alternative, under which the staff would 
leave things as they are by simply denying the amendment request. This 
no-action alternative is not feasible because it conflicts with 10 CFR 
40.42(d) requiring that decommissioning of source material facilities 
be completed and approved by the NRC after licensed activities cease. 
The no action alternative would keep radioactive material on-site 
without disposal. Additionally, denying the amendment request would 
result in no change in current environmental impacts. The environmental 
impacts of the proposed action and the no-action alternative are 
therefore similar, and the no-action alternative is accordingly not 
further considered.

Conclusion

    The NRC staff has concluded that the proposed action is consistent 
with NRC guidance and regulations. Because the proposed action will not 
significantly impact the quality of the human environment, the NRC 
staff concludes that the proposed action is the preferred alternative.

Agencies and Persons Consulted

    NRC provided a draft of this Environmental Assessment to the 
Maryland Department of the Environment for review on April 26, 2007. On 
May 30, 2007, Maryland Department of the Environment responded by 
email. The State agreed with the conclusions of the Environmental 
Assessment and otherwise had no comments.

III. Finding of No Significant Impact

    The NRC staff has prepared this EA in support of the proposed 
action. On the basis of this EA, the NRC finds that there are no 
significant environmental impacts from the proposed action, and that 
preparation of an environmental impact statement is not warranted. 
Accordingly, the NRC has determined that a Finding of No Significant 
Impact is appropriate.
