P'81R REFSPONSE R, `rSed Mays PS87 • Revegetation to appropriate land use • Protection of hydrologic balance Removal of Structures and Facilities Since the decision to abandon the No. 9 Mine was made prior to the installation of any portal related facilities, there are no structures and facilities to remove from the site. However, the dragline which sits adjacent to the highwall will be removed to allow reclamation of the site. The dragline is owned by Houston Oil and Gas Company and therefore, the dragline will be removed at their expense. Covering of Coal Seams All exposed coal seams will be covered with a minimum of four (4) feet of material. Backfilling and Grading The final exposed cut of the Williams Fork Strip Pit will be backfilled with the overburden material that lies adjacent to the cut: Track dozers will be used to push.the material into the cut. This will reduce the highwall slope to a maximum of 3H:1V. The present "disturbance topography" as well as the proposed reclaimed topography (post - disturbance) are presented on the Williams Fork Strip Pit Reclamation Plan Map (Map E 24). Disturbance and post disturbance cross - sections are presented on this same Map. The planned post- disturbance drainage profile (D -D') and plan view are shown on the Post - Disturbance Drainage Profile D -D' Map (Map E 24A) . This profile configuration is similar to natural drainages found within the permit area as shown by profile WF3 -WF3' on Map E 24B. No slopes on the planned reclaimed area will exceed 33.3% (3H: !V) The planned side slopes are less than those found in natural drainages within the permit area as shown by profiles WFl - WF1' on Map E 24C and WF2 ¢ WF2` on Map E 24B.
