ACCEPTANCE OF COMPLETION REPORT FOR NATURITA, COLORADO, VICINITY PROPERTY NT-069S
Dear Mr. Rael:
By letter dated November 3,1998, the U.S. Department of Energy (DOE) provided the Naturita, Colorado, Vicinity Property NT-069S Completion Report (VP CR) to the U.S. Nuclear Regulatory Commission (NRC) for review. The NRC staff's review of the VP CR is enclosed.
Concurrence by the NRC on this VP CR is required because special circumstances resulted in Supplemental Standards being invoked during remedial action. The NRC staff concludes that the information provided by DOE in the NT-069S CR provides reasonable assurance that supplemental standards for soil cleanup have been properly applied. Therefore, the NRC staff concurs that the use of Supplemental Standards and the remediation of the vicinity property were completed in accordance with U.S. Environmental Protection Agency standards. The signed NRC Review Form for Supplemental Certification of Vicinity Properties, showing NRC concurrence, is also enclosed.
If you have any questions concerning this letter or the enclosures, please contact the NRC Project Manager, Robert Carlson , at (301) 415-8165 Sincerely,
[Signedby]

U. S. NUCLEAR REGULATORY COMMISSION STAFF REVIEW OF THE
- COMPLETION REPORT FOR NATURITA VICINITY PROPERTY NT-069S The U.S. Nuclear Regulatory Commission (NRC) staff reviewed the 1998 version of the Vicinity Property Completion Report (VP CR) for the Naturita Vicinity Property (VP) NT-069S, MK-Ferguson Company, dated July 23,1998.
The VP CR describes the remedial actions (radiological cleanup) and verification activities performed at VP NT-069S. This site is lies within Montrose County, Colorado, west of the Naturita processing site on State highway 141.
Per agreement with the property owners, supplemental standards have been applied to residual radioactive material left in place on the hillside / steep slope areas in the northern section of the property, including Areas "J" and "K"in their entirety and portions of areas "A,""H,""I,""L," and "A-1." Due to the instability of the slopes, once disturbed, and the likely potential of surface erosion once all vegetation is removed from the hillsides, it was determined that the cost of remediation would far outweigh the benefit received from the removal of the windblown contaminated materials. Appendix A, Radiological Survey Data for the Supplemental Standard, and Appendix B, Supplemental Standards Recommendation, serve as documentation of the application of supplemental standards of the remaining areas of contamination and their current radiological conditions.
Because the reason for the NRC's review of this VP CR is that the supplemental standards were used at the VP, the NRC staff review has been limited to areas where supplemental standards were applied.
The radiological conditions within the Supplemental Standards areas are summarized as follows:
- a. Exposure rate range over the contaminated area (s) - 12 to 22 uR/hr
- b. Average exposure rate range over the contaminated area (s) - 17 uR/hr
- c. Maximum recorded Ra-226 concentration in accessible area (s)- 43.4 pCi/g
- d. Average recorded Ra-226 concentration - 14.4 pCi/g l
Background for the Naturita locale is an exposure rate of 13 uR/hr and 1.5 pCi/g of Ra-226. )
The data presented include background.
The VP CR provides a complete health risk analysis of the long term exposure of 100 mrem per 1 I
year, and short-term unusual exposure of 500 mrem per year. The analysis demonstrated that a person would have to be in the supplemental standards area (s) for a very lengthy period of time to receive exposure at those levels.

NRC Review nf Reviwd VP PR fnr NT.n609 ') Nnvember 100R The VP-CR also provides a thorough cost analysis for the remediation , which indicates that the benefit to be received from full removal of the contaminated materialis prohibitive. Therefore, application of the U.S. Environmental Protection Agency (EPA) 40 CFR 192.21 (c) criterion is more applicable than Criterion 192.21 (a).
NRC Staff Conclusion The NRC staff concludes tha the information provided by the DOE in the VP CR for the Naturita Vicinity Property NT-069S and other documents provides reasonable assurance that remediation of this VP and the use of supplemental standards were completed in accordance with EPA standards.
