U.S. Department of Energy 2155 Louisiana NE, Suite 4000 Albuquerque, NM 87110 l
SUBJECT:
VICINITY PROPERTY COMPLETION REPORT FOR THE RIFLE, COLORADO, VICINITY PROPERTY NUMBER RF-103
Dear Mr. Sena:
j
)
The U.S. Nuclear Regulatory Commission staff has completed its review of the Vicinity Property Completion Report (CR) and the Vicinity Property Certification Summary and Decision for vicinity property RF-103 (south of Highway 6 West) in Rifle, Colorado, submitted by letter dated August 9,1996.
NRC concurrence with this CR is required because the U.S. Department of Energy i
(D0E) applied supplemental standards during remediation.
Supplemental standards were applied in order to leave tailings contamination (approximately 1417 cubic yards over 8485 square yards) urder, and to 15 feet
)
from railroad tracks (portion of the mainline and six spur lines) owned by the Denver and Rio Grande Western Railroad.
Since complete remediation would have l
required the removal and replacement of 3180 feet of track in order to l
excavate the contaminated material, the railroad would not allow remediation cf those areas.
DOE based the application on criteria a and c of 40 CFR l
192.21 because of the owner's concerns and the hazardous conditions for remediation workers, and because the estimated remedial cost would be high considering the potential use of this portion of the property.
For th.t remediated portion of the property, none of the verification soil sampl9s recorded exceed the U.S. Environmental Protection Agency (EPA) stanJards for Ra-226 in soil.
Interior contamination was removed from beneath shed #2. As a result, working level and gamma' radiation (uR/hr) limits, as required by 40 CFR 192.12(b)(2), were achieved.
Based on NRC staff's review of the CR, it appears that DOE's application of supplemental standards was appropriate.
However, NRC staff concludes that the following items should be addressed before NRC can concur on the CR:
l 1.
CR Sections 3.1.2 and 3.2.2 imply that the working level criterion is 0.03 WL, but 40 CFR 192.12 (b)(1) states that every reasonable effort /U shall be made to achieve 0.02 WL. The CR statements should be
//
corrected.

Drawing RF-103-035 indicates that supplemental standards were planned or applied in the Radiological Engineering Assessment (REA). DOE should l
clarify if supplemental standards were indicated in REA, and if so, why l
NRC concurrence was not obtained prior to remediation.
If you have any questions concerning this letter, please contact the NRC Project Manager, Janet Lambert at (301) 415-6710.
