The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend a materials permit held under Byproduct Materials License No. 03-23853-01VA. The permit is held by the Department of Veterans Affairs (the Licensee), for its Southern Arizona VA Health Care System facilities, located at 3601 South 6th Avenue, Tucson, Arizona (Facility). Issuance of the amendment would authorize release of Building 32 (described below) for unrestricted use. The Licensee requested this action in a letter dated June 12, 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 June 12, 2007, materials permit amendment request, resulting in release of Building 32 for unrestricted use. License No. 03-23853-01VA was issued on March 17, 2003, pursuant to 10 CFR Parts 30 and 35, and has been amended periodically since that time. This license authorizes the Licensee to use byproduct materials at several Licensee facilities around the country, as authorized on a site-specific basis by permits issued by the Licensee's National Radiation Safety Committee. Under the license, the permits authorize the use of by-product materials for various medical and veterinary purposes, and for use in portable gauges.
The Facility is situated on a 116 acre site comprised of about 40 buildings, and is located in a mixed residential/industrial urban area of Tucson, Arizona. Within the Facility, Building 32 was constructed in 1969 as a single story block frame and brick structure. The building was used to house animals for research until July 1975 when it was used for interim storage and treatment (by disposal to sewer and incineration) of radioactive research and medical waste. The licensee ceased using licensed materials in Building 32 on September 1, 2004, and initiated surveys and decontamination of the building. Based on the Licensee's historical knowledge of the site and the conditions within Building 32, 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 Building 32 during September through November 2004. The results of these surveys along with other supporting information were provided to the NRC to demonstrate that the criteria in Subpart E of 10 CFR Part 20 for unrestricted release have been met.
Need for the Proposed Action
The Licensee has ceased conducting licensed activities in Building 32, and seeks the unrestricted use of Building 32.
Environmental Impacts of the Proposed Action
The historical review of licensed activities conducted in Building 32 shows that such activities involved use of the following radionuclides with half-lives greater than 120 days: hydrogen-3 (H-3) and carbon-14 (C-14). Prior to performing the final status survey, the Licensee conducted decontamination activities, as necessary, in the areas of Building 32 affected by these radionuclides.
The Licensee completed final status surveys on Building 32 on November 8, 2004. The surveys covered all areas of Building 32. The final status survey report was attached to the Licensee's amendment request dated June 12, 2007. The Licensee elected to demonstrate compliance with the radiological criteria for unrestricted release as specified in 10 CFR 20.1402 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 provide acceptable levels of surface contamination to demonstrate compliance with 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 in Building 32. The NRC staff reviewed available docket file records and the final status survey report to identify any non-radiological hazards that may have impacted the environment surrounding Building 32. 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 issuance of the proposed amendment authorizing release of Building 32 for unrestricted use is in compliance with 10 CFR part 20. Based on its review, the staff considered the impact of the residual radioactivity from Building 32 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 Building 32 meets the requirements of 10 CFR 20.1402 for unrestricted release. Additionally, denying the amendment request would result in no change in Start Printed Page 10293current 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.
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 Arizona Radiation Regulatory Agency for review on December 27, 2007. The State had no comments regarding the EA.
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.
