1'.4 UNITED STATES o NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 December 17, 1999 DOCKET NO: 70-734
LICENSEE: General Atomics (GA)
San Diego, California
SUBJECT:
SAFETY EVALUATION REPORT: SORRENTO VALLEY CENTRAL LAND AREA - RELEASE TO UNRESTRICTED USE (TAC NO. L31229)
BACKGROUND
In an application dated July 29,1999, GA requested their license be amended to remove authorized activities at the Sorrento Valley Central Land Area from the license, and to release this area for unrestricted use. This area is generally a parking lot and is associated with a previously decommissioned facility, the Sorrento Valley A (SVA) Fuel Manufacturing Facility, that was used to conduct licensed activities. The north half of the parking lot had been used for the temporary storage of radioactive waste boxes from the SVA Decommissioning Project.
These radioactive waste boxes had been properly packaged and sealed and the exteriors surveyed for removable contamination before being stored in this area. The licensee conducted a survey of the Sorrento Valley Central Land Area and provided the results of that survey along with their submittal. The licensee used the same methodology as used during decontamination and decommissioning of the other facilities previously released at the site.
DISCUSSION
GA completed the survey of the Sorrento Valley Central Land Area and submitted a final report entitled, "Final Radiological Survey Performed at General Atomics' Sorrento Valley Central Land Area," dated July 28, 1999. The survey methodology and decontamination procedures and techniques were the same rigorous procedures as used in the Building 2 laboratories, Building 30, Phases I and II, and other buildings and areas which have been previously released. NRC Region IV inspectors conducted in-process inspections and verified the licensee's survey results.
The licensee's survey data showed that there was no residual radioactivity in the Sorrento Valley Central Land Area and all readings were well below the criteria established in "Guidelines for Decontamination of Facilities and Equipment Prior to Release for Unrestricted Use or Termination of Licenses for Byproduct, Source or Special Nuclear Material," dated April 1993, as incorporated in GA Materials License SNM-696. Final contamination and radiation surveys, as well as sample results provided in the final survey reports for this area, demonstrate that the Sorrento Valley Central Land Area meets the approved criteria for release to unrestricted use.
Inspectors from Region IV performed ongoing evaluations of the licensee's methodology and performed confirmatory surveys which are documented in Inspection Report 70-734/99-01.

The Region IV inspectors determined the following:
"The licensee's report, "Final Radiological Survey Performed at General Atomics' Sorrento Valley Central Land Area," dated July 28, 1999, was reviewed and found acceptable. The inspectors performed a confirmatory survey of the land area. The survey consisted of alpha, beta and gamma measurements over several portions of the land area. No soil samples were taken. The beta readings ranged from 0-216 cm 2 dpm/100 cm 2 above background. The alpha readings ranged from 0 to 4 dpm/100 above background. The gamma readings at 1 meter ranged from 0-2 gR/hr above background. The results were consistent with the licensee's measurements which demonstrated that the area met the criteria for unrestricted release."
ENVIRONMENTAL REVIEW
Based on the information submitted by GA, the staff has determined that the changes to the license are related to decreased operations at the facility resulting from the proposed overall decommissioning of the site. Accordingly, the staff has determined that the criteria in 10 CFR 51.22(c)(1 1) for categorically excluding an action from an environmental review have been met.
Therefore, neither an Environmental Assessment nor Environmental Impact Statement is necessary for this action.
CONCLUSION
The staff coribludes that GA's request to reduce licensed activities meets regulatory requirements and that there is reasonable assurance that the proposed action will not adversely impact upon the health and safety of the public or the environment.
The Region IV Principal Inspector has no objection to this proposed action.
