The U.S. Nuclear Regulatory Commission (NRC) is considering the issuance of a license amendment to Source Materials License No. STC-133. This license is held by Defense Logistics Agency (DLA or the Licensee) at multiple sites. The site at issue is its Defense National Stockpile Center Start Printed Page 60771located at U.S. Highway Route 206 South in Somerville, New Jersey (the Facility). Issuance of the amendment would authorize the licensee to use site-specific Derived Concentration Guideline Levels (DCGLs) in a later survey of the Facility to determine if the Facility can be released for unrestricted use under the criteria in 10 CFR 20.1402. The use of the site-specific DCGLs requires an exemption to the definition of weighting factors in 10 CFR 20.1003. The Licensee requested this action in a letter dated October 19, 2005. 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 NRC plans to issue the amendment 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 October 19, 2005, license amendment request to use site-specific DCGLs as part of a later request (not yet submitted) to release the Facility for unrestricted use under the criteria in 10 CFR 20.1402. License No. STC-133 was issued on July 23, 1983, pursuant to 10 CFR part 40, and has been amended periodically since that time. This license authorized the Licensee to use unsealed source material for purposes of storage, sampling, repackaging, and transfer.
Based on the approved DCGLs, the Licensee will conduct surveys of the Facility and provide information to the NRC to demonstrate that the Facility meets the criteria in Subpart E of 10 CFR Part 20 for unrestricted release.
Need for the Proposed Action
The Licensee has ceased conducting licensed activities at the Facility, and seeks the approval of site-specific DCGLs through issuance of an exemption to the definition of weighting factors in 10 CFR 20.1003. The licensee needs these site specific DCGL values for later determining if the Facility meets the criteria for unrestricted use. NRC is fulfilling its responsibilities under the Atomic Energy Act to make a timely decision on a proposed license amendment that ensures protection of public health and safety and the environment.
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: natural uranium and thorium mixtures.
An amendment specifying the site specific DCGLs is required before the Licensee can use such DCGL values to later demonstrate compliance with unrestricted release criteria. The Licensee conducted site-specific dose modeling using input parameters specific to the Facility and a conservative assumption that all residual radioactivity is in equilibrium. Federal Guidance Report Number 13 was used to modify the dose conversion factors because it is based on an improved, more realistic dosimetry model. The selected critical age group is adults as the expected future use of this facility will be industrial. Based on the type of building, and its proximity to an existing railroad, there is no compelling evidence to indicate that the building will be used for other than industrial activities. The NRC has reviewed the Licensee's methodology and proposed DCGLs and finds that the proposed DCGLs are acceptable for use at the Facility. Federal Guidance Report Number 13, as an updated dosimetry model, uses different weighting factors than is published in 10 CFR part 20. The weighting factors are used to determine effective dose equivalent and total dose equivalent. Therefore, an exemption to the definition of weighting factors in 10 CFR 20.1003 is required to use Federal Guidance Report Number 13. The use of Federal Guidance Report Number 13 for dose modeling and weighting factors is acceptable for this Facility.
Based on its review, the staff has 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. 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.
The NRC staff has concluded that the site specific DCGLs identified by the Licensee are acceptable for use at its Facility. 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 EA to the State of New Jersey's Department of Environmental Protection for review on June 21, 2006. On July 20, 2006, the State of New Jersey responded by letter. The State agreed with the conclusions of the EA if the DCGL's are adjusted from the NRC's 25 millirem per year standard to the Department of Environmental Protection's remediation criterion of 15 millirem per year (N.J.A.C. 7:28-12.8(a)). While, 15 millirem per year is the State of New Jersey criterion, for the purpose of NRC consideration of the proposed action, the NRC must implement DCGLs that support the 25 millirem per year standard set forth in 10 CFR 20.1402. The Department of Environmental Protection also requests that the deed restriction referenced on page 2 of the letter dated April 26, 2006, “Defense Logistics Agency, Request for Additional Information Concerning Application for Amendment to License” [ML061220479] be in place before approval of NRC license termination. The NRC found that based on the type of building, railroad distribution, and truck access, there is no compelling evidence to indicate that the building will be used for other than industrial activities. NRC determined that no deed restriction will be necessary should the Licensee pursue its plans to seek the unrestricted use of its Facility.
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. Start Printed Page 60772Accordingly, the NRC has determined that a Finding of No Significant Impact is appropriate.
