Overburden was fragmented with explosives. Bulldozers prepared benches to allow for <br />drilling with a rotary drill. Drill holes were loaded with ANFO (ammonium nitrate - fuel oil) <br />or other approved blasting agents. Fragmented overburden was removed by dragline and <br />spoiled into the previous pit. <br />Coal was fragmented (primarily through the use of explosives) and removed from the pit. <br />Hydraulic shovels loaded haul trucks which transported raw coal from the pit directly to the <br />Hayden Station generation plant over county and private roadways by a private hauler. Direct <br />haul to the plant precluded coal preparation at the mine site. <br />Cast over spoils were graded to approximate original contour, and salvaged topsoil was <br />redistributed. Topsoil replacement depth is approximately one foot. Areas of topsoil <br />redistribution were generally drill seeded the first fall planting season following completion of <br />topsoil spreading. <br />Reclamation of pit areas was concurrent with mining. All final pit highwalls were reduced <br />and the entire disturbed area regraded. Topsoil was replaced and vegetation was reestablished. <br />Water usage at the site is limited to dust suppression and maintenance, Water used in <br />maintenance and dust suppression activities is withdrawn from Pond 008. Seneca Coal <br />Company has secured water rights for all water usage and for replacement in the event that <br />off -site water supplies are damaged or depleted. <br />Operations at the permitted mining area will involve maintenance and limited reclamation <br />activities only during the remainder of the permit term. <br />7 <br />
