RE: Ten Day Notice X-91-02-355-003
Dear Mr. Hagen:
The Division received the above-referenced Ten Day Notice on
October 16, 1991 . As the tenth day after receipt fell on a weekend,
our response became due on Monday, October 28, 1991 .
We have reviewed the reclamation cost estimate performed by the Western
Support Center (WSC) . This estimate served as the basis for the Ten-Day
Notice. The major cost differences between the WSC estimate and our estimate
are the road width reduction and structural demolition costs .
Road Width Reduction
In our original estimate and in the WSC' s estimate, an average haul road width
of 55 feet was assumed. However, our staff conducted an intensive fifteen-day
inspection of the mine site roads this summer, in conjunction with the U.S.
Forest Service. One outcome of the inspection was the determination that the
average road width is 37 feet. This observation was confirmed using aerial
photos of the site.
Therefore, using site specific data, the road reduction calculation was
reevaluated. We have utilized the WSC equipment costs and productivity
estimates , but used the actual average road width of thirty-seven feet, rather
than the fifty-five feet assumption. The cost associated with road width
reduction is estimated to be $281 ,595.00, which is lower than the original
MLRD estimate, and is $484,293.00 less than the WSC estimate .
Structural Demolition
OSM included a cost of $535,544.00 for debris handling and disposal . This
cost is an add-on expense above and beyond the unit costs provided in Means
Building Construction Cost Data. The demolition unit costs projected in Means
includes debris handling, and assumes disposal will occur within a five mile
radius . Disposal of these facilities within this radius is entirely feasible
and , in fact, desirable , given that significant backfilling will occur at this
site.
