SUPPLEMENTARY INFORMATION:

I. Introduction

The U.S. Nuclear Regulatory Commission (NRC) is considering the issuance of a license amendment to Byproduct Material License No. 46-06377-04. This license is held by the United States Department of Commerce, National Oceanic and Atmospheric Administration, Northwest Fisheries Science Center (the Licensee). The license authorizes the Licensee to possess and use cadmium-109, lead-210, hydrogen-3, and carbon-14 at two locations for purposes of conducting research and development activities. At one of these locations—the Licensee's field office known as the Mukilteo Research Station (the Facility) in Mukilteo, Washington—licensed activities have ceased.

By letter dated November 21, 2005, the Licensee requested the NRC to authorize release of the Facility for unrestricted use, which would result in the removal of the Facility as a location of use from the NRC license.

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 this EA, the NRC has concluded that a Finding of No Significant Impact (FONSI) is appropriate with respect to the proposed action. The amendment will Start Printed Page 31865be issued to the Licensee following 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 November 21, 2005, license amendment request, resulting in a license amendment which would release the Facility for unrestricted use. License No. 46-06377-04 was issued in the 1950's pursuant to 10 CFR part 30, and has been amended periodically since that time.

The Facility is situated on property located adjacent to Puget Sound and consists of a main research office building and several smaller support buildings in the yard. The main facility consists of laboratories and offices and is approximately 10,000 square feet (929 square meters) in size. Within the Facility, use of licensed material was confined to three specific laboratories totaling about 380 square feet (35 square meters) as well as a 350-square foot (28 square meter) portable shed located adjacent to the main research building. The Facility is located in a commercial district in Mukilteo, Washington.

The Licensee ceased licensed activities at the Facility in 1987. The licensee conducted a final status survey at the Facility in November 2004. 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 radiation safety procedures, were required. As allowed by Section 7.4 of NUREG-1757, “Consolidated NMSS Decommissioning Guidance,” Volume 1, the Licensee was not required to submit a decommissioning plan to the NRC. 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.

Need for the Proposed Action

The Licensee has ceased licensed activities at the Facility and seeks the unrestricted use of its Facility.

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, carbon-14, cadmium-109, and lead-210. Prior to performing the final status survey, the Licensee conducted decontamination activities, as necessary, in the areas of the Facility affected by these radionuclides.

In November 2004, the licensee conducted a final status survey, which covered the three laboratories, hallways outside the laboratories, and the adjacent storage shed. The final status survey report was attached to the Licensee's amendment request dated November 21, 2005. 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 Appendix H to NUREG-1757, “Consolidated NMSS Decommissioning Guidance,” Volume 2.

The Licensee used guideline levels that were comparable to the derived concentration guideline levels (DCGLs) developed 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 part 20 for unrestricted release. The Licensee's final status survey results were below these DCGLs, and are thus 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). Further, no incidents were recorded involving spills or releases of radioactive material at the Facility. Accordingly, 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 staff finds that the proposed release of the Facility described above for unrestricted use is in compliance with 10 CFR 20.1402. The NRC has found no other activities in the area that could result in cumulative environmental impacts. 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

Alternatives to the proposed action discussed below are: (1) The no-action alternative; and (2) require the Licensee to take some alternate action.

1. No-action Alternative: As an alternative to the proposed action, the staff could 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 have ceased. Additionally, this denial of the application 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.

2. Environmental Impacts of Alternative 2: A second alternative to the proposed action would be to deny the Licensee's request and instead apply the 10 CFR 20.1403 criteria for restricted release of the Facility. However, restricted releases are not favored in cases where the requirements of 10 CFR 20.1402 for unrestricted release can be met, and the NRC's analysis of the Licensee's final status survey data confirmed that the Facility meets these requirements. Accordingly, the NRC finds that choosing this second alternative to the proposed action is not warranted, and this alternative is eliminated from further consideration.

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 Washington Department of Health for review on October 13, 2006. On January 29, 2007, the Department of Health, Division of Radiation Protection, 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 Start Printed Page 31866or 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.
