I. Introduction The U.S. Nuclear Regulatory Commission (NRC) is considering Start Printed Page 28172allowing the Department of the Navy (Navy) to issue an amendment to a materials permit in accordance with NRC Byproduct Materials License No. 45-23645-01NA. The NRC approval would authorize the Navy to release, for unrestricted use, Building 133 at the Naval Air Depot in Cherry Point, North Carolina. The Navy requested this action in a letter dated May 21, 2006. 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 proposed action will be taken 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 Navy's May 21, 2006, request to release Building 133 at the Naval Air Depot in Cherry Point, North Carolina (the Facility), for unrestricted use. Building 133 is a one-story open structure used for repair and maintenance of aircraft engines. This Facility is located within a secure military base in a rural area, and use of licensed materials was confined to three shop areas: the Aircraft and Component Clean, Strip, and Corrosion Control Shop; the Machine Repair Power Plant Shop; and the Engine Parts Repair Shop. Each shop maintained dedicated, marked 55 gallon drums for storage of low level radioactive waste (LLRW) generated from Mg-Th operations. At the end of each shift in which Mg-Th maintenance was performed, areas were cleaned with dedicated shop vacuums equipped with HEPA filters. Mg-Th components were cleaned in an enclosed parts washer to prevent the spread of contamination. In March 2006, the Navy ceased licensed activities at the Facility, and initiated a survey and decontamination of Building 133. Based on the Navy's historical knowledge of the site and the conditions of Building 133, the Navy determined that only routine decontamination activities, in accordance with their NRC-approved, operating radiation safety procedures, were required. The Navy was not required to submit a decommissioning plan to the NRC because worker cleanup activities and procedures were consistent with those approved for routine operations. The Navy conducted Facility surveys 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 permit termination. Need for the Proposed Action The Navy is requesting approval of this permitting action because it has ceased conducting licensed activities at its Facility, and seeks its unrestricted use and termination of the permit. Environmental Impacts of the Proposed Action The historical review of licensed activities conducted in Building 133 shows that such activities involved use of the following radionuclides with half-lives greater than 120 days: Thorium 232. Prior to performing the final status survey, the Navy conducted decontamination activities, as necessary, in the areas of Building 133 affected by these radionuclides. The Navy conducted a final status survey in May 2006. This survey covered Building 133 and, conservatively, the LLRW storage room in Building 134 and the Outside LLRW Storage Pad. The final status survey report was attached to the Navy's request for permit amendment approval dated May 21, 2006. The Navy elected to demonstrate compliance with the radiological criteria for unrestricted release as specified in 10 CFR 20.1402 by developing a derived concentration guideline level (DCGL) for thorium of 450 disintegrations per minute gross alpha activity per 100 square-centimeters area (α dpm/100 cm2) for Building 133. The past history of Building 133 suggests that use of a surface criterion is appropriate. The Navy developed their final DCGL by utilizing the DANDD code and its default industrial scenario to calculate the “default” DCGL for thorium. The Navy then utilized the suggested resuspension factor in NUREG-1720 “Re-Evaluation of the Indoor Resuspension Factor for the Screening Analysis of the Building Occupancy Scenario for NRC's License Termination Rule—Draft Report” to calculate a site-specific DCGL. The Navy developed a ratio of the default resuspension value in the code and the re-evaluated value from draft NUREG-1720 and multiplied the “default” DCGL for thorium by this ratio to result in a site-specific 450 α dpm/100 cm2 DCGL for thorium. The Navy thus determined the maximum amount of residual radioactivity on building surfaces, equipment, materials, and soils that will satisfy the NRC requirements in Subpart E of 10 CFR Part 20 for unrestricted release. The NRC reviewed the Navy's methodology and proposed DCGL, and concluded that the proposed DCGL is acceptable for use as release criteria for Building 133. The Navy's final status survey results were below this DCGL, 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. The staff finds there were no significant environmental impacts from the Facility's use of radioactive material. 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 Building 133. 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 Building 133 for unrestricted use and the termination of the Navy's materials permit is in compliance with 10 CFR 20.1402. Based on its review, the staff considered the impact of the residual radioactivity at Building 133 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 Navy's final status survey data confirmed that Building 133 meets the requirements of 10 CFR 20.1402 for unrestricted release and for permit 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 Start Printed Page 28173alternative 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 North Carolina Department of Environment and Natural Resources, Radioactive Materials Branch for review on February 13, 2008. On February 14, 2008, the North Carolina Department of Environment and Natural Resources 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. IV.
