RE: Somerset/Sanborn Creek Mine, File No. C-81-022, Technical
Revision-23
Dear Mr. Stover:
The Division has completed it's initial adequacy review for the
technical revision-23 (TR-23). Overall, the Division agrees with
Somerset's position that a highwall will not exist after
reclamation is completed and therefore, rule 2.06.5(2) for variance
from approximate original contour, is the underpinning rule that
will dictate the final reclaimed configuration of the Bear Canyon
site. The review was then conducted using rule 2.06.5(2) as the
criteria for approval.
The following questions are organized to address specific sections
of rule 2.06.5(2) as outlined in your submittal.
2.06.5(2):
(a) The Division agrees that leaving an access road is
beneficial and desirable for public access through this
area. Along this vein, it would seem necessary to leave
a certain amount of fill below the road for support and
stability. With a couple of exceptions mentioned later in
this review, the proposed reclamation plan appears to
utilize the necessary material to complete backfilling
while retaining an adequate foundation to support an
access road.
(b) The proposed post-mining land use is equal to the pre-
mining land use. Both land uses are undeveloped/public
utilized primarily as public access for hunting and
grazing livestock.
(c) No comment.
(d) The Division has reviewed the LISLE calculations used to
make the watershed improvement demonstration. After
reviewing the calculations and assumptions used therein,
