SUBJECT:
REVIEW 0FJUSTIFICATI0EFORAPPLICATIONOF SUPPLEMENTAL STANDARDS AT VICINITY PROPERTY GJ-18426-MR $ 3 m
w Background b By submittal dated January 28, 1988, the Department of Energy (00E) supplied the final Radiological and Engineering Assessment (REA) which requested the application of supplemental standards on the contaminated area for vicinity property GJ-18426-MR.
Discussion Vicinity property GJ-18426-MR contains twenty-four areas that identify residual radioactive contamination around the root cellar and garage located on the property. The remedial action site contains an enclosed root cellar and garage. Radiological data were collected in a dug out storage area at 2315 North 1st Street. This structure is not considered to be a habitable space and there is no anticipated change of land use within the next five years. The enclosed root cellar is constructed of 2-foot thick rubblestone walls with a combination of heavy timber,and light frame roof system over a concrete slab floor. The contaminated materials are present under the slab floor. DOE states that physical evidence of the contaminants are not mill tailings related (which under the UMTRA program guidelines would not qualify for removal) and that all mill tailings have been removed from the area surrounding the structure.
Areas A and B are er.terior tailings deposits and are scheduled to be removed. Areas C and 0 are east of the building. The walls of the OFC : : : : : : :

j N 40-WM39/RSH/88/03/01/1 MAR 2 4 1988 "storage garage" would be made structurally unstable by the removal of the concrete floor slab and would remain unstable.
The exposure rate at three feet above the building floor ranges from 18 pR/hr to 81 pR/hr, and averages 25 pR/hr. Radium concentrations in soil in contaminated areas ranged from 9 to 143 pCi/g with average concentrations reported as 27 pCi/g.
The cost ettimate to perform remedial action on this property without supplemental standards applied is estimated at $40,141. The cost estimate with supplemental standards applied is estimated at $15,560.
This cost estimate to perform remedial action without application of supplemental standards is very high relative to the potential health benefits associated with the removal of residual radioactive material buried at depth.
By letter dated January 27, 1988, the owner was informed and concurred with DOE's intention of applying supplemental standards to the property in question.
Conclusion Based on my review of the subject REA, associated letters and in accordance with criteria "d" of 40 CFR 192.21 and the NRC's "Guidelines for Justifying the use of Supplemental Standards, in 40 CFR Part 192",
dated July 3, 1986, DOE satisfied the criteria deemed necessary to apply supplemental standards. I recommend that concurrence be granted for the application of supplemental standards for the property designated as GJ-18426-MR. I Is f Ralph S.
