The mining process includes clearing of vegetation, topsoil removal, overt Burden blasting and <br />removal, and coal blasting and removal. Reclamation will be contemporaneouswrth mining, <br />and includes backfilling, grading, topsoil redistribution, and reestablishment of vegetation. <br />Vegetation will be cleazed and either disposed of in the active pit, or placed on reclaimed <br />azeas for use by wildlife as cover. <br />Topsoil will be removed in advance of mining operations by scraper equipment, and will <br />then be stockpiled or redistributed when possible. Stockpiles will be temporarily stabilized <br />with the establishment of vegetation. <br />Overburden will be blasted and removed with a dragline, then spoiled into the previous pit. <br />The initial box cut spoil will be temporarily placed on an adjacent unmined <<rea, and the <br />spoil subsequently double handled for placement back in the pit once the next pit has been <br />opened. <br />Coal is ripped or shot, removed by loader, and transported via of]f highwa}~ trucks to a <br />stockpile located in the northeast tip of the permit azea, at the junction of Ro:ids A and B. <br />From there, coal is transported via Road A to the Hayden Station lpower plaint or to the <br />Hayden Gulch Loadout facility. <br />No crushing, screening, or washing of coal is proposed. Since no coal processing is planned, <br />the operation will not produce coal mine waste. Non-coal waste will be disposed of offsite <br />at an approved dump site. <br />Spoiled overburden is graded by bulldozers to approximate origirral conta~ur. Several <br />drainages will be reconstructed in the mined areas. Topsoil is redistributed by scrapers to <br />a average thickness of 1.8 feet. The approved reclamation seed mix will then b<: drill seeded <br />in the fall. If topsoil redistribution is completed in the spring a cover crop will be sown, <br />followed by the permanent mix in the fall. Concentrated islands of seeded and transplanted <br />shrubs will be established on approximately seven percent of the reclaimed area. <br />At the end of mining, all surface facilities will be removed, the areas regraded, topsoil <br />redistributed, and revegetation accomplished as described above. <br />Impacts to surface water and ground water will be mitigated and monitored. Surface runoff <br />from all disturbed azeas will be channeled to a sedimentation pond (Pond 1~~) located in <br />Armand Draw. Disturbed azea runoff from subsequent mining blocks will lbe routed to <br />Ponds 11, 12, 13, and 14. <br />Surface water will be monitored upstream and downstream of the site on Grassy Creek and <br />Armand Draw during the first permit term. Monitoring of Sage Crc:ek will tie reinitiated <br />two yeazs prior to mining in the Sage Creek basin. <br />Yaut Mine ]Q July 6, 1995 <br />
