RE: King Coal Mine; C-1981-035;
Technical Revision No. 26 (TR26), Review
I was requested to review the above referenced technical revision specifically regarding the
topsoil handling and reclamation plan for the disturbances proposed with this revision. Also, I
was requested to conduct a reclamation cost estimate for the proposed revision.
Topsoil Handling and Reclamation Plan
The operator provided a plan for plugging and sealing the proposed monitoring wells and
revegetating the disturbance. However, more information is required regarding surface
reclamation for the well clusters.
The following adequacy questions pertain to their topsoil handling and reclamation plan for this
revision:
• Revised sections 2.04.6 -page 7 and 2.05.4 -page 20 indicates the four monitoring well
clusters are outside of the existing permit area. Revised sections 2.04.10 -page 2, 2.04.11 -
page 3, 2.04.9 -page 3 indicates the well clusters are all within the permit area. The King
II Mine — Lease Map submitted with TR26 shows that Clusters MW -1, MW -1
(Alternate), MW -3 and MW -4 are outside of the DRMS Permit Boundary. Please revise
the permit sections to clarify the locations of the monitoring wells.
• Please revise section 2.05.4 of the permit to include a plan for backfilling and grading the
proposed drill pads for the monitoring well clusters in accordance with Rule 2.05.4(2)(c).
• The soils resources information contained in the King II Mine permit section 2.04.9 does
not cover all the disturbed areas for the proposed monitoring well Clusters MW -1, MW -3
and MW -4. Also, it is difficult to ascertain which soil series Cluster MW -2 falls in given
the quality of the Coal Lease Map submitted with TR26. The proposed revised pages
indicates a "natural resource survey" of the proposed drill sites will be conducted and the
