Reclamation Liability, G.E.C. Strip Mine, Permit No. C-81-037 ~ ~F Cp~~R s „~',e/A ~ ~ O ~, ~+~ Y+n ~ rBi6 ~ Roy Ramer Governor VichaelB Lonp Division Director Summary The Division is currently in the process of developing a Reclamation Bid Document for the reclamation of the Section 24 portion of G.E.C. Minerals Permit No. C-81-037. During this process, a difference of opinion developed between the Division and the landowner regarding the reclamation liability for certain mine waste piles in the east half of Section 24. Numerous sources were examined to ascertain the source of this mining waste, as mining in this area has been attributed to no less than five underground operations and two strip mining operations. Three waste deposits totalling less than 3 acres in extent were critically examined: the coal waste piles north and west of the tipple pond, the coal in the drainage between the tipple and the Orphan Pit, and the shale pile adjacent to the tie-across haul road. The result of this portion of the Division's investigation finds that the G.E.C. reclamation responsibility for these mine waste piles is restricted to the road that passes over the coal in the drainage between the tipple and the Orphan Pit, and to the coal waste piles that lie west of the tipple pond. All other coal waste associated with these deposits appear to have existed prior to G.E.C.'s involvement, and will thus not be included in the current Bid Document package. Description of Investigation On September 10, 1992, Cathy Begej inspected the G.E.C. permit area with the landowner, Dr. W.D. Corley. The objective of this inspection was to review the reclamation plans associated with the July 10, 1992 Bid Document. During this inspection, Dr. Corley indicated that certain mine waste that lay north and west of the tipple pond had been placed there by the Corley No. 6 Mine, while the Division had historically attributed this material to G.E.C. In addition, Dr. Corley asserted that a portion of the material in the drainage between the tipple and the Orphan Pit was attributable to G.E.C., as was a pile of shale east of the Orphan Pit.
