Reference:
Soil Decontamination Criteria for the Decom-missioning of the UNC's Facility (Draf t)
Gentlemen:.
UNC has reviewed the referenced document, which proposes the application of certain soil decontamina-tion limits for the decommissioning of the UNC Recovery Systems uranium recovery facility in Wood River Junction, Rhode Island.
Our comments to the draft NRC decontami-nation criteria are attached to this letter.
If you have any questions rega'rding these comments, please contact me or Mr. K. Helgeson.
Very truly yours, U"C RECOVERY SYSTEMS 4

9 ATTACHMENT TO LETTER, RJG 81-47, Dated MARCH 9, 1981 R. J.
GREGG to W. T. CROW UNC RECovCRY SYSTEMS COMMENTS TO 1
DRAFT NRC SOIL DECONTAMINATION CRITERIA UNC has the following comments relative to the draft NRC soil decontamination criteria.
While these are the only comments we have at this time, we reserve the right to respond to any changes made to the draft document.
Natural Background Consideration Section II.
D.
UNC is currently in.the process of measuring the concentration of the various radionuclides in soil samples taken from surrounding background locations.
The results of these evaluations will be transmitted to the NRC when they are available.
We assume that the decontamination levels are subject to reassessment by the NRC based on the background measurement results.
Section II.
E.
2 - Inhalation of Radon and Its Daughter It is not clear why the NRC has chosen a flux level equivalent to that which would result from a soil concentration of 3 pCi/g of radium-226, when 5 pCi/g is the level receiving uniform utilization under other government programs (e.g.,
EPA Proposed Standards for Inactive Uranium Processing Sites; DOE FUSRAP Program, NRC criteria for Docket 40-8035, Latty Avenue Site, Hazelwood, Missouri).
W
.e wculd appreciate your reassessment of this proposed limit and modification to a more reasonable level.
Sections II.
E.
3& 4
- Inhalation of Particulates and Ingestion of Radionuclides Based on the Note to Table 5 and the heading to Table 12, we assume that:
1.
verification of acceptability to limits involving inhalation of resuspended soil only requires measure-ment of the top centimeter of the soil, and 2.
verification of acceptability to limits involving in-gestion (vegetation, beef, milk) only requires measure-ment of the top 15 centimeters of the soil.
