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-
28473-01. This license is held by Neurogen Corporation (the Licensee), 
for its Neurogen Branford facility (the Facility), located on Northeast 
Industrial Road in Branford, Connecticut. 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 September 1, 2008. 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 1, 2008, 
license amendment request, resulting in release of the Facility for 
unrestricted use and the termination of its NRC materials license. 
License No. 06-28473-01 was issued on May 8, 1990, pursuant to 10 CFR 
part 30, and has been amended periodically since that time. This 
license authorized the Licensee to use unsealed byproduct material for 
purposes of conducting research and development activities on 
laboratory bench tops and in hoods.
    The Facility is situated on 8.8 acres, and consists of four one- 
and two-story buildings located at 15, 35, and 45 Northeast Industrial 
Road. The buildings contain approximately 132,200 square feet of office 
space and laboratories. The Facility is located in a mixed industrial/
commercial area. Within the Facility, use of licensed materials was 
confined to 15 areas: Laboratories 055, 071, 073, 215, 313, 314, 315, 
316, 320, 335, 362, and 662, used for research activities; and Rooms 
134 and 361, used for low-level radioactive waste storage.
    In March 2008, the Licensee ceased licensed activities and 
initiated a survey and decontamination of the Facility. 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 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 a 
final status survey between March 28 and August 11, 2008. This survey 
covered the 15 areas where licensed materials were used or stored. The 
final status survey report was attached to the Licensee's amendment 
request dated September 1, 2008. 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, and in soils, that will satisfy the NRC requirements in 
Subpart E of 10 CFR

[[Page 74764]]

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 the State 
of Connecticut Department of Environmental Protection (DEP) for review 
on October 9, 2008. On November 6, 2008, DEP responded by e-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.
