<br />The underground mining equipment not used in the reclamation <br />activity will be stared in the =_torage area until removed from <br />the minesite to the county dumps or sold as scrap. Non-coal <br />wastes generated during the mining operation, such as grease, <br />lubricants, paints, flamable liquids, garbage, and other <br />combustibles will be stored on the surface facilities area in <br />trash containers to be disposed of in the county dumps. ,The <br />buildings wilt also be dismantled and removed from the <br />property. Any concrete foundations which, if left in place <br />would be covered with less than two feet of cover after <br />obtaining final grades, will be removed and placed in the <br />underground workings. The portals will then be sealed using <br />seals as shown on Drawing 8: Typical Portal Seals. <br />If reclamation occurs before all of the mineable reserves are <br />extracted from underground, the portal structures will reamin <br />in place and be covered. The lease requires Eastside Coal <br />Company to maintain the integrity of the underground mine <br />including portals and -access thereto for possible future <br />mining/exploration activities. If the coal reserves accessed <br />by the portals is exhausted, the portal structures will be <br />broken and placed in the underground workings behind the:.seals. <br />The coal waste and rock material present in the surface <br />facilities area will be used to backfill around the portal <br />areas to the greatest extent possible. Any excess material <br />will be removed to the approved waste disposal site. Any soil <br />material in the surface facilities area which, after removal of <br />the coal waste and rock surfacing, is free from contamination <br />by coal will be used to cover the coal and rock material. <br />The Caterpillar Performance Handbook, Edition 14, indicates <br />topsoil has an expansion factor of 30%. During replacement of <br />the soil an 8-10% loss of loose volume results due to <br />compaction occurritrg during placement of the soli. The ' <br />resultant is a 20% swell factor from the original bank ya~^ds to <br />reclaimed in place yards. ~ <br />Four feet of soil will be salvaged from the waste disposal <br />site. The total amount of soil to be salvaged from the waste <br />disposal site is 9,;100 bank yards. Approximately 6,000 yards <br />will be used in covering the waste pile with two feet of <br />material. The excess of 5,000 yards will be available to cover <br />the reclaimed surface facilities area where coal waste is <br />exposed to obtain a maximum of two feet of material aver coal <br />waste. <br />108 Revised 8/89 <br />
