Dear Mr. Themelis:
We have reviewed the Radiological and Engineering Assessment (REA) for the Central Valley Water Reclamation Facility (CVWRF) in Salt Lake City that was prepa ed by the State of Utah and forwarded to us by Mark Matthews of your office. Based on the results of this review, wa conclude that the revised REA adequately addresses tha October 22, 1981 NRC comments on the draft REA, and therefore resolves the concerns expressed in our January 4,1985 letter to you.
NRC hereby concurs in the REA preferred Option 2 conditional to the items listed in the enclosure. This option involves application of supplemental standards to the contaminated materials under and adjacent to tanks in order to preserve structural integrity of existing tank foundations.
Note that in accordance with Condition A of the enclosure, concurrence in the CVWPF remedial action does not include the staging area and the area for the Taylorsville-Bennion sewer line bypass. These areas are on the Vitro -
processing site and their cleanup and certification for unrestricted use must be handled as part of the Vitro site cleanup.
Should you have any questions regarding this transmittal, please contact me or Dennis Sollenberger of my staff.
Sincerely, OMnd deseu by 62 u. Hisemboehm Lec B. Higginbotham, Chief Lcw-level Waste and Urenium Recovery Projects Branch Division of Waste Nnagement Of fice of Material Safety 8510280511 WASTE 050925 and Safeguards PDR PDR WM-55
