C. E. Johnston -2- July 12, 1993 protection on transmission lines owned by others within a permit area. The transmission line is 660 feet long and is constructed with three poles. 6. No response required. 7. The quantity of coal waste that will require excavation is 2,000 cubic yards. See response to item 8. 8. Enclosed is a new Figure 2 - Coal and Non-Coal Waste Reclamation & Disposal Plan that presents atypical section of how the site will be backfilled. The sequence of the backfilling operation will be as follows: 1. Place coal and non-coal waste in the disposal area. 2. Grade the bench material up and back over the disposal area to form AOC. 3. Place topsoil, seed and mulch. The disposal area could be up to 700 feet long. It has a capacity of approximately 12,700 cubic yards. The following material will be placed in the disposal area: Waste Source Cubic Yards Coal Waste - To Be Moved to Disposal Area 2,000 Coal Waste - Located in Disposal Area 1,900 Rail Road Ballast 1,100 Concrete (400 X 1.5 Swell) 600 Pavement (100 X 1.5 Swell) 150 Sediment from Pond (Max Allowed by Permit) 1,500 Total Required Disposal Area Capacity 7,250 The disposal area has an excess capacity of about 5,450 cubic yards (12,700-7,250). If the disposal were completed filled, the contours of the reclaimed surface would increase approximately one foot as compared to the original ground surface. This one foot rise from AOC is not considered significant. 9. I do not believe that cross-sections A-A', B-B' and C-C' need to be included in the volume calculations shown on Map 13. Section C-C' does not cut the coal pad therefore would not contribute to the quantity calculation. Sections A-A' and B- B' are taken "in between" other sections. They would not actually contribute anything to the volume calculation except a closer spacing of the sections in two areas.
