SUBJECT:
REVIEW OF JUSTF.FICATION FOR APPLICATION OF SUPPLEMENTAL STANDARDS AT VICINITY PROPERTY GJ-77003-0T Backa mund By submittal dated June 8, 1909, the Department of Energy (DOE) supplied the final Radiological and Enginee. ing Assessment (REA) which requested the application of supplemental standards on the contaminated area for vicinity property GJ-97003-0T.
This property is a portion of the Downtown Shopping Park, located on Main Street, between Fourth and Fifth Streets, including the sife streets from Main Street north and south to the alleys. The design for the remedial action of GJ-97003-0T pertains only to the sidewalk portions of a total of 19 properties along the 409 and 500 Blocks of Main Street.
The DOE assessment presented three remedial action options with health risk assessments, volume est.imates of materials that would be removed, cost estimates to perform remedial action, and the recommended action.
Discussion The three remedial action options considered for the Downtown Shopping Park are: no action, partial removal and complete removal.
The uranium mill tailings contamination exists beneath approximately 16,000 square feet of sidewalks and landscape planters to the assessed depth of 16 inches (measures from the top of the sidewalk) in the 400 Block of Main Street.
The DOE requested to pursue the option of partial removal. The design drawings show that the first 10 feet of sidewalk (from the building toward the sewer 8010060179 880004 OlbME PNU ,

line) along 455 Main Street is not contaminated and the radon daughter concentrations are below EPA standards. The highest outside gamma reading is 68 pR/hr. The maximum radium concentration in the contaminated area is 54.7 pCi/gm.
The total estimated cost for partial removal, including work on both sides of Main Street and along the side streets is estimated at $67,148. The estimated volume of materials to be removed under this option is 532 cubic yards.
Without the application of supplemental standards the total cost is estimated at $181,089.
Conclusion The efore, based on my review of the subject REA, associa ed correspondence and in accordance with Criterion "b" and "c" 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 reco: amend that concurrence be cranted for the application of supplemental standards for partial removal of contaminated soils for the properties designated at GJ-97003-0T.
