RE:
Proposed Solid Waste Fixation, Transportation and Burial, SNM-1107, hket 70-1151 Based upon our telephone conversation of March 23, 1979, I have incorporatsi additional information into the Enviromental Safety Controls section on page 3 of our original subnittal dated March 22, 1979. Please replace page 3 of the March 22, 1979 submittal with the attached page 3 dated March 23, 1979.
Thank you.
Very truly yours, WESTItEOUSE ELECIRIC CORP.

Prior to basin excavation, representative soil sa:rples will be taien and analyzed for
^
uranien and fluorides to establish the baseline conditions. Following rmoval of the treated sludge frcm the basin and annually thereafter, the soil will be sampled for both uranian and fluorides to determine the extent of the leaching into the soil.
Sampling points will be established to assure the representativeness of the sampling.
An evaluation will then be made to determine the impact of the residual uranium and fluoride on the environment. The evaluation will include the potential leaching of these cwpents into the water table and the dispersion into the atnosphere under drying conditions. A copy of this evaluation will be sent to you for in&-Hmal purposes.
Typically, the evaluations will use consewative assumptions for novment of the con-taminants through the soil and into the uuter table. Decontamination will be conducted to maintain average ground m ter concentrations beloa 5 mg per liter for fluorides and less than FTC for unrestricted areas for uraniun. For airtorne, resuspension of the w
material into atnesphere will be m1 minted under unusual drying condiHmn acempanied by high wind conditions. Decontamination will be conducted to maintain air concentra-tions below 2 ng per m3 fluorides and less than FTCafor unrestricted areas for uranium.
Samples of treated sludge have been subjected to 1.eaching studies in which aainnized water was passed through the sludge and filtered. The leachate was subjected to de-layed neutron analysis with uraniun concentration below the detection limit of 0.003 ppu. Consequently, no leaching probles are expected.
Test wolla " downstream" of the diked hanin will nonitor any migration of fluoriaan and uranium into the water table. Typically, the wells are 60 feet deep and extend into the water table. In addition, ground water samples will be collected fran a ditch which is located " downstream" of the basin. Well water and grcundwater samples will be collected quarterly and analyzed for fluorides and gross alpha. Action levels will be consistent with the limits described above for water concentrations.
No environmental airborne problm s are anticipated. The air sanpling program described under " Radiological Safety Control" above should be *pate to verify the expected low airborne levels. If residual levels dictate, continuous environmental air <mpling will be established to nonitor any material resuspended into the air. Action levels will be consistent with the limits described above for airborne concentrations. It is expected that the basin area will be retained as the area. for future fixation operations.
Consequently, the site will be maintained as a " Restricted Area" as definsi in sub-paragraph 2.1.1 of the existing license.
