pit and compacted by the reclamation equipment. All spoils will be graded, • <br />highwalls reduced and spoil piles and depressions eliminated except those <br />depressions that existed prior to mining. <br />Backfilled material will be placed by the dragline to minimize adverse <br />effects on groundwater, minimize off-site effects and to support the approved <br />postmining land use. <br />Cut and fill terraces are not proposed at the Seneca II Mine, except as <br />required by 9.03 .117)(a)Ivii). <br />Hox cut material at the Wadge "left open" pit located approximately between <br />coordinates 18,300 East 25,500 South and 17,150 East 27,400 South has been graded <br />into the existing topography and a portion reclaimed. This pit was excavated <br />during 1981 and 1982 and portions graded in 1983. <br />Hackfilling of this pit is accomplished as the Wadge East pit is mined. An <br />examination of Exhibit 12-1 will show the East pit cuts abutting into the Wadge • <br />"left open^ pit as each cut is mined up the hill. As the dragline approaches the <br />left open pit, spoil material excavated from each East pit cut is backfilled into <br />the left open pit. This procedure was also followed as each west pit cut abutted <br />into the southern extension of the left open pit which has been reclaimed. The <br />remaining open pit is approximately 90-95 feet deep. <br />• <br />TR-36 72-53a Revised 09/04 <br />
