SUPPLEMENTARY INFORMATION:

I.Introduction

    The U.S. Nuclear Regulatory Commission (NRC) is considering the 
issuance of a license amendment to Byproduct Materials License No. 06-
30667-02. This license is held by CuraGen Corporation (the Licensee), 
for its facility located at 322 East Main Street, in Branford, 
Connecticut (the Facility). Issuance of the amendment would authorize 
release of the Facility for unrestricted use and termination of the NRC 
license. The Licensee requested this action in a letter dated July 31, 
2007. 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 July 31, 2007, 
license amendment request, resulting in release of the Facility for 
unrestricted use and the termination of its NRC materials license. 
License No. 06-30667-02 was issued on April 8, 2003, pursuant to 10 CFR 
Part 30, and has been amended periodically since that time. This 
license authorized the Licensee to use unsealed byproduct material at 
the Facility for purposes of conducting research and development 
activities on laboratory bench tops, incubators, and in hoods.
    The Facility is comprised of a 52,000 square foot building on 3.5 
acres of land and consists of general office space and laboratories. 
Use of licensed materials was confined to 300 square feet of the 
building known as Area 311B. The Facility is located in a mixed 
residential/commercial area. Within the Facility, the radionuclides of 
concern were hydrogen-3 and carbon-14 because their half-lives are 
greater than 120 days.
    In October 2004, the Licensee ceased licensed activities at the 
Facility and initiated survey and decontamination actions there. Based 
on the Licensee's historical knowledge of the site and the conditions 
of the Facility, the Licensee determined that only routine 
decontamination activities, in accordance with their NRC-approved, 
operating radiation safety procedures, were required. The Licensee was 
not required to submit a decommissioning plan to the NRC because worker 
cleanup activities and procedures are consistent with those approved 
for routine operations. The Licensee conducted surveys of the Facility 
and provided information to the NRC to demonstrate that it meets the 
criteria in Subpart E of 10 CFR Part 20 for unrestricted release and 
for license termination.

Need for the Proposed Action

    The Licensee has ceased conducting licensed activities at the 
Facility, and

[[Page 71975]]

seeks the unrestricted use of its Facility and the termination of its 
NRC materials license. Termination of its license would end the 
Licensee's obligation to pay annual license fees to the NRC.

Environmental Impacts of the Proposed Action

    The historical review of licensed activities conducted at the 
Facility shows that such activities involved use of the following 
radionuclides with half-lives greater than 120 days: hydrogen-3 and 
carbon-14. Prior to performing the final status survey, the Licensee 
conducted decontamination activities, as necessary, in the areas of the 
Facility affected by these radionuclides.
    The Licensee conducted final status surveys on July 2-3, 2007. The 
final status survey report was attached to the Licensee's amendment 
request letter dated July 31, 2007. The Licensee elected to demonstrate 
compliance with the radiological criteria for unrestricted release as 
specified in 10 CFR 20.1402 by using the screening approach described 
in NUREG-1757, ``Consolidated NMSS Decommissioning Guidance,'' Volume 
2. The Licensee used the radionuclide-specific derived concentration 
guideline levels (DCGLs), developed there by the NRC, which comply with 
the dose criterion in 10 CFR 20.1402. These DCGLs define the maximum 
amount of residual radioactivity on building surfaces, equipment, and 
materials, that will satisfy the NRC requirements in Subpart E of 10 
CFR Part 20 for unrestricted release. The Licensee's final status 
survey results were below these DCGLs and are in compliance with the As 
Low As Reasonably Achievable (ALARA) requirement of 10 CFR 20.1402. The 
NRC thus finds that the Licensee's final status survey results are 
acceptable.
    Based on its review, the staff has determined that the affected 
environment and any environmental impacts associated with the proposed 
action are bounded by the impacts evaluated by the ``Generic 
Environmental Impact Statement in Support of Rulemaking on Radiological 
Criteria for License Termination of NRC-Licensed Nuclear Facilities'' 
(NUREG-1496) Volumes 1-3 (ML042310492, ML042320379, and ML042330385). 
The staff finds there were no significant environmental impacts from 
the use of radioactive material at the Facility. The NRC staff reviewed 
the docket file records and the final status survey report to identify 
any non-radiological hazards that may have impacted the environment 
surrounding the Facility. No such hazards or impacts to the environment 
were identified. The NRC has identified no other radiological or non-
radiological activities in the area that could result in cumulative 
environmental impacts.
    The NRC staff finds that the proposed release of the Facility for 
unrestricted use and the termination of the NRC materials license is in 
compliance with 10 CFR 20.1402. Based on its review, the staff 
considered the impact of the residual radioactivity at the Facility and 
concluded that the proposed action will not have a significant effect 
on the quality of the human environment.

Environmental Impacts of the Alternatives to the Proposed Action

    Due to the largely administrative nature of the proposed action, 
its environmental impacts are small. Therefore, the only alternative 
the staff considered 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 30.36(d), requiring that decommissioning of 
byproduct material facilities be completed and approved by the NRC 
after licensed activities cease. The NRC's analysis of the Licensee's 
final status survey data confirmed that the Facility meets the 
requirements of 10 CFR 20.1402 for unrestricted release and for license 
termination. 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 the NRC's unrestricted release criteria specified in 10 CFR 
20.1402. 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 
Connecticut Department of Environmental Protection for review on 
November 6, 2007. On November 30, 2007,the State of Connecticut, 
Department of Environmental Protection responded by electronic mail. 
The State agreed with the conclusions of the EA, and otherwise had no 
comments.
    The NRC staff has determined that the proposed action is of a 
procedural nature, and will not affect listed species or critical 
habitat. Therefore, no further consultation is required under Section 7 
of the Endangered Species Act. The NRC staff has also determined that 
the proposed action is not the type of activity that has the potential 
to cause effects on historic properties. Therefore, no further 
consultation is required under Section 106 of the National Historic 
Preservation Act.

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.
