SUBJECT:
REVIEW 0F JUSTIFICATION FOR APPLICATION OF SUPPLEMENTAL STANDARDS AT VICINITY PROPERTY ED-00706-0T
Background
By submittal dated April 6,1988, the Department of Energy (DOE) supplied the final Radiological and Engineering Assessment (REA) which requested the application of supplemental standards on the contaminated area for vicinity property ED-00706-0T.
Discussion Windblown tailings have contaminated the waste water sludge and bottom material of the Edgemont, South Dakota, 20-acre sewage lagoon. The lagoon was built in 1957, and sludge has accumulated to an average depth of approximately 14 inches.
The propcsed remedial action plan is to remove the windblown tailings from the area surrounding the lagoon down to the low water level.
Supplemental standards are requested for the sludge / bottom material because of the high cost relative to the long-term benefits. Four remedial action alternatives were examined to remove and dispose of the sludge. The costs to implement the alternatives range from $752,129 to
$1,630,265, with a construction period from 166 to 274 days.

WM-039/RSH/88/06/02/3 3,y g 1988 A sample of the sludge / bottom material s'howed a radium-226 concentration of 25 pCi/gm. Exposure rate measurements taken at water level on the lagoon range from 16 pR/hr to 56 pR/hr. The higher readings are reported to be caused by windblown deposits on the dikes around the edge of the lagoon.
Water samples were collected from two wells and the results showed that no se.nple exceeded the EPA Water Quality Standard.
The use of the land for the lagoon is not expected to change in the foreseeable future, and there is no occupancy on or near the lagoon.
There.is no degradation to the quality of the water discharged from the lagoon to the Cheyenne River.
- 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 E0-00706-0T.
