SUBJECT:
SAFETY EVALUATION REPORT: BUILDING 39 - SORRENTO VALLEY "B" (SVB) RELEASE CERTAIN PORTIONS TO UNRESTRICTED USE BACKGROUND in accordance with application dated December 22,1998, GA requested their license be amended to remove authorized activities at certain portions of Building 39 SVB (offices not
' impacted by operations involving nuclear material) from the license, and release those portions of Building 39 for unrestricted use. The offices will be torn down and sent to a locallandfill. GA conducted a survey of the facilities and provided the results of that survey along with their submittal. The licensee used the same methodology as during the decontamination and decommissioning of the other facilities previously released at the site.
DISCUSSION '
GA has completed the survey of Building 39 office areas. They submitted a final report entitled,
" Final Radiological Surveys Of Selected Buildings 39 (SVB) For Release To Unrestricted Use,"
dated December 9,1998, and requested the offices be release for unrestricted use in a letter dated December 22,1998. The survey methodology and decontamination procedures and
' techniques were the same rigorous procedures as used in the Group 6, Group 7, Group 8, Group 9 laboratories and Building 30 phases I and 11 ' hich have been previously released.
w l
The licensee's survey data showed that there was no residual radioactivity in the Building 39 offices _ and that all readings were well below the criteria established in " Guidelines for i
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 General Atomics Materials Ucense SNM-696. Inspectors from Region IV performed a confim1atory survey (Inspection Report 70-734/98-03), and determined the following:
"A confirmatory survey was conducted on the portions of Building 39 to be released to unrestricted use. The survey included several locations on the interior floor, inside and outside walls, metal roof, and the gravel, tar and insulation removed from the roof.
l Several instruments and detectors were used to measure alpha, beta and gamma radiation. The results were all within the release limits specified in the Site Decommissioning Plan. The results were all background except the gravel from the roof
. which was above background but within the release limits. "

2 The licensee has implemented a program for the conduct and documentation of final surveys that follows the guidance contained in Draft NUREG/CR-5849, " Manual for Conducting Radiological Surveys in Support of License Termination."
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 overali decommissioning of the site. Accordingly, the staff has determined that the criteria in 10 CFR 51.22(c)(11) 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 concludes 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.
