AUG 4 1988 URF0:RSH Oocket No. 40-WM039 040WM039190E MEMORANDUM FOR: Docket File No. 40-WM039 FROM: Ralph S. Heyer, Project Manager Licensing Branch 2 Uranium Recovery Field Office, Region IV
SUBJECT:
REVIEW OF JUSTIFICATION FOR APPLICATION OF SUPPLEMENTAL STANDARDS AT VICINITY PROPERTY GJ-97005-0T
Background
By subinittal dated July 5,1988, 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-97005-0T.
This property is a portion of the Downtown Shopping Park, located on Main Street, between Sixth and Seventh Streets, including the side streets from Main Street north and south to the alleys. The design for the remedial action of GJ-97005-0T portains only to the sidewalk portions of a total of 15 properties along the 600 Block of Main Street.
The DOE assessment presented three remedial action options with health risk assessments, volume estimates 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 17,000 square feet of sidewalks and landscape planters to the assessed depth of 16 inches (measures from the top of the sidewalk) in the 600 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 line) along 602 Main Street is not contaminated. Although the radon daughter 0010040174 000004 sg O A PDR WASTE .iM WM-39 PNU

r ]
2 AUG 4 1988 contentrations at 602 Main Street exceed EPA standards DOE stated that partial removal will reduce indoor radon to acceptable levels.
The highest outside gamma reading is 148 pR/hr. The maximum radium concentration in the contaminated s.rea is 84.6 pCi/gm.
The total estimated cost for partial removal, including work on both sides of Main St,reet and along the side streets is estimated at $45,231. The estimated volume of materials to be removed under this option is 339 cubic yards.
Without the application of supplemental standards the total cost is estimated at $178,999.
Conclusion Therefore, based on my review of the subject REA, associated correspondence and in accordance with Criterica "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 recommend that concurrence be granted for the appifcation of supplemental standards for partial removal of contaminated soils for the properties designated at GJ-97005-0T.
