6. As discussed and as delineated by the dotted line on
Attachment D to the revision, WECC will assume operational
responsibility for the area bounded on the south by the
upland diversion ditch, on the north by the outslope of
the berm between the stockpile and Bear Coal Company's
drainage ditch adjacent to the river, on the west by the
sedimentation pond and spillway constructed to control
runoff from the stockpile area and on the east by the toe
of the spoil stockpile. WECC will also be responsible for
reclaiming the road accessing the stockpile.
7. WECC will reclaim the stockpile area .and appurtenant
structures in accordance with the Mining and Reclamation
Plan for Bear Mines 1 and 2 and the revisions noted in
CMLRD's Findings Document of Compliance for Bear Mines 1,
2 and 3 dated May 10, 1982. That is, WECC will regrade
and rip the surface prior to reseeding. The area will be
revegetated with the seed mixture described in Table 10 to
the Bear Mines 1 and 2 Mining and Reclamation Plan.
Revegetation success will be determined as described in
• Bear Coal Company's Mining and Reclamation Plan for Bear
Mines 1 and 2 and as revised in CMLRD's Findings Document
of Compliance for Bear Mines 1, 2 and 3. Bonding calcula-
tions have been revised to reflect reclamation costs in
compliance with Bear's approved reclamation plan and are
attached.
8. The upland diversion ditch will be approximately 65 feet
from the toe of the backfilled Bear Portal No. 1 and
approximately 30 feet from.~the toe of backfilled Bear
Portal No. 2.
9. WECC's present Mining and Reclamation Plan indicates that
the area to be excavated for the second coal storage silo
will be backfilled and contoured. WECC intends to revise
its reclamation plan to reclaim the rock face below the
access road to its approximate original contour. Thus we
no longer intend to backfill that area upon reclamation.
This will be addressed in our response to CMLRD's mid-term
review of the Mt. Gunnison permit.
10. A discussion of calculations and delineations of the 100-
.year flood plain of the North Fork can be found in the Mt.
Gunnison Mining and Reclamation Plan at Section 2.8.1.7
entitled "Flooding Evaluation". A letter from the highway
department is also attached indicating that their re-
channelling of the North Fork in the vicinity of the Bear
