-Docket No. WM-48 040WM048950E Mark L Matthews Acting Project Manager Uranium Mill Tailings Projec'c Office Department of Energy P. O. Box 5400 Albuquerque, New Mexico 87115 Deur Mr. Matthews:
We have reviewed your July 18, 1989 submittal requesting approval for supplemental standards and Modification No. 1 for the Durango Remedial Action Plan.
We agree that supplemental standards are applicable for the residual material along the' Animas River.
Supplemental standard approval is for the area
. described in Figure 2 of your submittal only. We have concluded that the supplemental standard criteria (40 CFR Part 192.21) concerning risk of injury to workers and environmental harm to be applicable to this proposal.
We therefore, approve proposed Modification No. I to the Durango, Colorado Final Remedial Action Plan (Rev. 1, dated ~6/23/89).
During a visit to the site on September 6, 1989, members of my staff observed this particular area.along with several other areas that are' currently being considered for supplemental standards or vicinity property designation. While examining these areas, a small " seam" of crystallized uranium salts which has formed along the river bank along the slag and original ground interface was pointed out.
The deposit is thought to be the result of an old spill on the slag pile that is slowly leaching through the slag and daylighting at the river bank.
Due to problems encountered with excavating and drilling in the slag, the extent of this uranium deposit has not been defined.
Your staff indicated that DOE has no plans to cleanup this area as the hazard averaged over-the entire slag pile will be negligible _ We do not consider this to be consistent with the approach of reducing exposure to the public to levels 0
I 8910030376 890919 PDR WASTE WM-48 PNU
2 SEP 191989 as close to the standards as is reasonably achievable.
Therefore we suggest that DOE reexamine the possible hazard to the public along the accessible river bank.
If you have any questions please contact me or D. L. Jacoby of my staff on FTS 776-2805.
Sincerely, ff y
