SUBJECT:

VICINIT', PROPERTY COMPLET!ON REPORT FOR.THE RIFLE. COLORADO, VICINITY PROPERTY NUMBER RF-103

Dear Mr. Rael:

The U.S. Nuclear-Regulatory Commission staff has completed its review of the Jage changes submitted by.the U.S. Department of Energy (DOE) by letter dated r bruary 11, 1997, in response to NRC comments on the Vicinity Property e

Com)letion Report (CR) for vicinity property RF-103 (south of Highway 6 West) i in 11fle Colorado.

NRC concurrence with this CR is required because DOE applied supplemental standards to the remediation of this vicinity property.

Supplemental standards were applied in order to leave tailings contamination (approximately 1417 cubic yards over 8485 square yards) under, and out to 15 feet from railroad tracks owned by the Denver and Rio Grande Western Railroad (a portion of the mainline and six spur lines).

Since complete remediation would have required the removal and replacement of 3180 feet of track in order i

to excavate the contaminated material., the railroad would not allow remediation of those areas.

DOE based the application of supplemental standards on criteria a and c of 40 CFR 192.21 because of the owner's concerns and the hazardous conditions for remediation workers. and because the estimated remedial cost would be high conside ig the potential use of this portion of the property.

For the remediated portion of the property, none of the verification soil samples recorded exceed the U.S. Environmental Protection Agency (EPA) standards for Ra-226 in soil.

Interior contamination was removed from beneath 1

shed #2. As a result, working level and gamma radiation (uR/hr) limits, as L

required by 40 CFR 192.12(b)(2), wem achieved.

}

Based on its review of the CR and the information provided in DOE's response to comments, the NRC staff concurs that DOE's remediation of the vicinity

' Review Form for Supplemental Certification of Vicinit property, which includes the application of sup)lemental standards, was appropriate and was completed in accordance wit1 the EPA Standards.

The NRC l

j NRC concurrence, is enclosed.
