Dear Mr. Edge:
p#
u b
The U. S. NurIsar Regulatory.Corpmission staff has reviewed the 1997 annualinspection report -
for the Durango, Colorado Title i sits. Based on this review, we conclude that the inspections and the. routine remedial measures that are being performed are acceptable.'
o The staff notes that minor gullying,' erosion, sedimentation, and vegetation growth have been observed at the site. ~Although none of these problems appear to be significant at inis time,-
your continued observations of the problems are importani, i.
b For the Durango site, and possibly other licensed sites, it would be useful if the U.S.
Dopertment of Energy (DOE) could provide further information regarding the reletive
- (
' significance of specific problems that are occurring, particularly if the problems are unexpected.-
In addition, it would be usefulif DOE could analyze the problems and determine at what point the problems at a specific sits becoms significant. For example, the Durango site is experiencing some sedimentation and vegetation growth in the diversion channels; in this case, minor sedimentation likely will not affect channel capacity or velocities in the channel.
l However, it is important to know at what point the problem will become significant, to properly direct and manage future site inspections and to determine the need for mitigative measures.
+
Recognizing that some conservatisms have been used in the dedgn, it is also important to -
L
' know if these conservatisms have been considered by DOE in its analysis of site problems.
The staff rMiuests that DOE consider these suggestions and requests that a meeting or -
5 conference call be held within the next 34 months to discuss the need for establishing _ site-specific mitigation criteria for sHes experiencing problems.
This review was performed by Ted Johnson. lf you have any questions, he may be contactM at (301) 415-6658.
Sincerely, o
