ACCEPTANCE OF COMPLETION REPORT FOR NATURITA, COLORADO, VICINITY PROPERTY NT-066S
Dear Mr. Rael:
By letter dated March 17,1999, the U.S. Department of Energy (DOE) provided the Naturita, Colorado, Vicinity Property NT-066S 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 NRC on this VP CR is required because special circumstances resulted in Supplemental Standards being invoked during remedial action. NRC staff concludes that the l information provided by DOE in the NT-066S CR provides reasonable assurance that )
supplemental standards for soil cleanup have been properly applied. Therefore, the NRC staff I I
concurs that the use of Supplemental Standards and the remediation of the vicinity property were completed in accordance with the 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 cor' .the NRC Project Manager, Robert Carlson, at (301) 415-8165.
Sincerely, 1

NRP Review nf Reviced VP PR fnr NT.fM6R Mnrch 1044 s ,
l U. S. NUCLEAR REGULATORY COMMISSION STAFF REVIEW OF THE COMPLETION REPORT FOR NATURITA VICINITY PROPERTY NT-066S 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-066S, dated
, July 29,1998. <
The VP CR describes the remedial actions (radiological cleanup) and verification activities performed at the VP NT-066S. This site lies within Montrose County, Colorado, south of the Naturita processing site and west of State Highway 141. -
Remedial action was not performed on specific areas of VP NT-066S at the request of its owners.
The remedial action was not performed due to the instability of the slopes and the high potential of surface erosion if all vegetation was removed from the steep hillsides. Additionally, the high risk of injury to personnel performing the remedial action and the cost of remedial action would ,
far outweigh the benefit received from the removal of the windblown' contaminated materials.
Appendix A of VP NT-066S," Recommendation for Application of Supplemental Standards,"
serves as documentation of the application of supplemental standards for these specific 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 related to the use of the supplemental standards for the VP.
The radiological conditions within the Supplemental Standards areas are summarized as follows:
- a. Dose equivalent range at ground level over the contaminated area (s) - 15 to 34 R/hr
- b. Average dose equivalent at ground level over the contaminated area (s)- 21 pR/hr {
Q
- c. Ra-226 concentration range for coewninated soils - 0.28 to 44.88 pCi/g j i
I
- d. Average Ra-226 concentration for contaminated soils - 7.67 pCi/g l i
Background for the Naturita locale is an exposure rate of 13 R/hr and 1.5 pCi/g of Ra-226. l The data presented include background. j 4
A l
The VP CR provides a complete health risk analysis of the long-term exposure of 100 mrem per ,
year and short-term unusual exposure of 500 mrem per year. The health risk analysis also j demonstrated that a person would have to be in the area (s) for a very lengthy period of time to ;
receive those types of exposures. ;

o ;
The VP-CR also provides a thorough cost analysis for the remedial action, which indicates that the benefit to be received from full removal of the low-level contaminated material is prohibitive.
Therefore, application of the U.S. Environmental Protection Agency (EPA) 40 CFR 192.21 (c) criterion is applicable.
a NRC Staff Conclusion The staff thus concludes that the information provided by the DOE in the VP CR and other
. documents provides reasonable assurance that remedial action for this VP and the use of supplemental standards were appropriate in accordance with EPA standards.
