-The Radiological and Engineering Assessment (REA),1 Revision 1,,for vicinity-
' property numbers DU-544/545 was-originally submitted on September 13, 1989, in
[J which the Department of Energy-(DJE) requested NRC concurt.ence on the- - +
. application of supplemental standards. -Additional REA'submittals were.made on s
February l14,-1990, and April 24'--1990.

1 The! proposed' remedial action is to apply supplemental standards to-3 y2
- approximatelyL733,680 squa're yards (about 150 acres) of open' land _on Smelter Mountain,' owned by the S+ ate of Colorado-(DU-545) and private parties'(DU-544).

4 The area exhibits the characteristics of windblown contamination with the soil.
sampling results sporadically ranging from less:than;1.3 to-205 pCi/g.
The
?4 hillsidesf reportedly have an; average grade of 75 percent, naking-cleanup-of the p"
' deposits difficult.
DOE estimated that' cleanup costs for DU-544 to be about 1 million dollars and about' 5 million dollars for DU-545.
The proposed 7' '.
remedial action is to leave the contsmination in place.
l}4-f;,
' DOE:has-applied for supplemental standards for these two properties based on
~
E,
-the high cost rchtive.to long-term benefit (40.CFR 192.21c) and potential risk of in' jury.to workers during cleanup operations (40 CFR 192.21a). Additionally stressed is the potential harm to the environment resulting from cleanup j
operat, ions.
Their assessment of the radiological hazard'to-tk public is based L
oncthe; assumptions that, there will be no change in the current ' land use.
The f
private landowners,:however, base indicated that they may not agree with the L
assumption that the land is uninhabitable.
00E was therefore requested by-
.i
- letter dated January 12,'1990, to readdress.the hazard assuming the area is t
L Ui sE.

- concentration.would not exceed the allowable limit
- of 0.03'WL.-
Conclusion' The' location of the contaminated material, the, fact that t'he land use is'not likelylto change, and the' low.public' health hazard compared to the cost of" complete.remediation.' justify the-' application of-supplemental standards for
- these properties. 7 Ths REA dated January 22, 1990', meets thel criteria established in
.40 CFR 192.21(c) necessary to apply supplemental standards'.
The proposedi
- remedial actions are ' reasonable under the circumstances and' the requirements _of.,
140 CFR 192.22(a)'are therefore satisfied.
The staff concurs with-00E that.
supplemental standards be applied for. vicinity property numbers D0-544/545S.
