SUBJECT:
WATERTOWN GSA PROPERTY DECOMMISSIONING PLAN
Dear Mr. Waskiewicz:
j l
The purpose of this letter is to document the bases for applying the grandfathering provisions of l 10 CFR 20.1401(b)(3) to the U.S. General Services Administration (GSA) Property in j Watertown, Massachusetts. After careful review of the documentation for this site, we cor,clude that an adequate decommissioning plan for the GSA property was submitted and approud by the NRC before August 20,1998.
The use of source material was authorized at the GSA property by AEC License No. SUB 238 from May 9,1961 to January 17,1974, when the area was released for unrestricted use by the AEC. Title to the propedy was transferred to the GSA on August 16,1968, as excess property from the U.S. Army Materials Technology Laboratory (AMTL) and U.S. Army Watertown Arsenal. Records found by the U.S. Department of Energy indicated that the GSA site was surveyed in 1967 and found to be contaminated in excess of the criteria then in use for uncontrolled release. Since 1981, Leveral surveys and decontamination activities have been completed at the site. However, the site remained contaminated and was included in the NRC Site Decommissioning Management Plan (SDMP) list. In May 1992, at the request of GSA, the U.S. Army Corps of Engineers, New England District (NED), agreed to remediate the GSA propedy. l Although the GSA site does not have a specific NRC license, NED has submitted several work plans for site characterization, remediation and decommissioning of the site. NRC approval of g these. work plans was transmitted to NED by letters dated April 15,1993 and June 10,1994.
The latter work plan, Additional GSA Site Characterization, dated May 26,1994, referenced the
\ g '
SMe Safety and Health Plan for the Decommissionina. Demolition and Site Restoration of the Research Reactor and Decommissionina of the Radiation Facilities at the U.S. Army Materials Technoloav La%ratory. The Facility Decommissionina Plan prepared by Roy F. Weston Co. In 1992, for the AMTL provided the radiological criteria that was approved by the NRC and resulted in the release of the AMTL facilities from NRC license SUB-238 by NRC in July 1997. Both of these documents were used at the GSA site when NED completed extensive survey and remediation activities in 1994 and 1995 using the AMTL Decommissioning Plan. On January 25, 1996, NED submitted its Radioloaical Characterization and Final Survey Report. This report also referenced use of the AMTL Decommissioning Plan that was approved by the NRC.

As we have discussed, additional remediation may be needed to address contamination remaining in a burn-pit and some surface land areas. We anticipate providing yeur office comments from the NRC on the adequacy of the characterization of the remaining areas of contamination by the end of this year. After receipt of NRC comments, we understand that your office may submit a feasibility study that will evaluate future decommissioning options at the site.
Although there will be some revision to the details of how the remaining contaminated areas of the facility will be physically remediated, the existing AMTL decommissioning plan with an updated radiation protection program to reflect the current U.S. Army Corps radiation protection procedures are expected to be adequate to ensure worker and public health and radiological safety.
Based on the above, we conclude there is an approved decommissioning p'an for the GSA site under the grandfathering provisions of 10 CFR Part 20, Subpart E. Please recognize that, should your future evaluations propose a restricted release for the bum-pit area, the dose based limits and other requirements of Subpart E would apply.
If you have any questions, please contact Marie Miller of my staff or me at 610-337-5205 or 5200, respectively.
Thank you for your cooperation.
