• the methods previously described. Overland Conveyor All of the overland conveyor systems and facilities will be dismantled including supports and footings. All material capable of being salvaged will be salvaged. The unsalvageable material may be placed at the toe of the faceup fiighwall at the portal area prior to backfilling and/or placed in the SA underground workings near the portal entries. The affected areas will be backfilled and graded with the adjacent spoil material from prior strip mining operations and spoil from the conveyor activities. The post-mining topography of the area is presented in the Reclamation Plan Map (Map 29). Upon completion of the backfilling/upgrading operations, the salvaged plant growth media, which material will be salvaged prior to initiation of grading operations and temporarily placed adjacent to the area to be regraded, will be redistributed over the area. The backfilling/grading operations will leave the area in a roughed condition which will minimize slippage of the top dressing. The disturbed areas will then be drill-seeded with the appropriate land use seed mixture, rangeland/wildlife or pastureland, for which the area is to be reclaimed. The seed will be applied with a rangeland drill at the rate of 17.25 pounds PLS/acre for the rangeland/wildlife mixture and 17.0 pounds PLS acre for the pastureland mixture. If it is necessary to apply the seed by the broadcast method, the seeding rate will be doubled. A straw mulch, applied at a rate of two (2) tons/acre, will be spread over the seeded sites. The mulch will be crimped into the top dressing or a tackifier applied to ensure its stability. Contour ditches or furrows will be constructed on the reclaimed slopes to reduce erosion. The ditches or furrows will be approximately 20 to 50 feet apart and have check dams placed at periodic intervals. The ditches will be maintained until the vegetation becomes established. It is anticipated that the ditches will fill with sediment in one (1) or two (2) years following vegetation establishment. No. 9 Portal Area As previously discussed in Section 2.05.3, Operation Plan -Permit Area, an additional waste disposal site is planned far the backfill area at the No. 9 Portal. Therefore, reclamation activities at the No. 9 Portal will be an ongoing process. However, the original post-mining land use planned for the No. 9 Portal area will remain as cropland, and the seed mixture in the revegetation plan presented later in this section will remain intact. However, the No. 9 portal area may be seeded with the pastureland seed mixture if this land use coincides with adjacent land use. The seed mixture will be determined at the time the site is reclaimed in accordance with the present land use (i.e. cropland or pastureland). It is currently envisioned that the shop/office building, scrapyard, and associated pad will remain intact until CEC no longer needs these facilities. However, prior to any backfilling, facilities including the electrical equipment', surface coal haulage equipment (conveyor belt system), ventilation equipment, and miscellaneous mining scrap located in the portal excavation were removed from the site. Topsoil, which was stockpiled on the berm surrounding the portal excavation, will be salvaged and temporarily stored until it is ready to be redistributed over the regraded area. The stockpiled topsoil will be seeded with the appropriate topsoil stockpile seed mixture. The portal entries, located at the bottom of the portal excavation were covered with 15 feet of material. All exposed coal seams were then be covered with a minimum of four (4) feet of inert backfill material. The 15 feet of inert material placed over the portal entries effectively sealed the No. 9 portals. This portal sealing plan has previously been approved by MSHA. Once the initial backfilling is completed, waste material including coarse reject will then be hauled periodically to the excavation and placed in 2-foot lifts. Placing of coarse reject in the excavation will be an ongoing process which will continue until it reaches a maximum height of four (4) feet below the planned reclaimed surface. The coarse reject material and coal waste that had been previously stockpiled at the No. 9 Portal site was Permit Renewal No. 3 2.05-27 7/15/98
