EXHIBIT D MINING PLAN (CONT)
2 and 2A was rerouted to the north side of Phase 2A, which allows
for combining the two phases into one mining phase, and then to
be reclaimed as one reservoir. This does not significantly
affect the Mining or Reclamation Plans, and it actually reduces
reclamation since there is no Phase 2A to backfill .
Phase 3 - Increase acreage by adding 7 . 90 acres for a
conveyor crossing over the transportation corridor that separates
Phase 3 and Phase 4 . An existing dirt road will be used for
access to the area. As the mine has developed, it has been
decided the best way to transport raw material from the eastern
properties of the mine (located on the east side of US Highway
85) to the Plant Site on the west side of HWY 85 is via an
elevated conveyor system. A 7 . 90 acre conveyor corridor shall be
added between Phases 3 and 4, on properties owned by Cannon Land
Company. There are two Right-of-Ways (ROWs) crossing the Cannon
properties, which are held by the Union Pacific Railroad (UPRR)
and Colorado Department of Transportation (CDOT) for HWY 85 . An
elevated conveyor system will be built to span the ROWS . No
parts of the structure will be placed in the Rights of Ways and
L.G. Everist, Inc (LGE) is working with both ROW owners to get
formal agreements to cross their structures . The agreements will
be filed with the Division when received. If these agreements
are not reached, this corridor will not be used, and the elevated
conveyor system will not be constructed.
With these acreage additions, the permit area will increase by
26. 62 acres and become 667 . 97 acres more or less .
UNDERDRAIN- Revise reclamation plan to include the underdrain
built between Phase 1 and Phase 2, which was installed in the
summer of 2024 . The underdrain is shown on all amended Map
Exhibits . The underdrain starts in two places - along the
southeast side of Phase 2, and along the northeast side of Phase
1 . The two sections connect and the underdrain continues between
the north slurry wall of Phase 1 and the south slurry wall of
Phase 2 . The outlet of the underdrain is past the west side of
the phases, near the river. The outlet' s location was what
resulted in a violation due to a small area of disturbance
outside the existing western permit line. The underdrain design
and hydrologic evaluation information was submitted to the
Division during the permit investigation and is included in the
APPENDIX. The underdrain maintains the hydrologic balance and
maintains the groundwater elevation outside the slurry wall to
its historic levels, by allowing the groundwater to seep into and
