• Annual Reclamation Report (SCC, 2000) and confirm the mean soil replacement thickness for the first two five-year permit terms. Soil Salvaee and Storase The disturbance area from which soil was salvaged and the soil stockpile sites as of December 31, 2003 aze shown on Seneca II-W Mine 2003 reclamation Map. The actual volume of soil salvaged and stockpiled from 1989 through December 31, 2003 was determined by field survey of existing soil storage stockpiles. The Seneca engineering staff completed the base and existing elevations for each stockpile. The stockpile volumes as of December 31, 2003 are listed in Table 03.1. As of December 31, 2003, 69.7 acre-feet of soil were stockpiled along the tie-across haul road and 1018acre-feet of soil were stockpiled in the mining area. Soil Balance and Replacement The soil balance is calculated for Seneca Il-W Mine by comparing the disturbance area that requires soil replacement as of December 31, 2003 with the soil reserve in stockpiles. The disturbance area for Seneca lI- W Mine, shown on the map, with exception to the tie-across haul road, totaled 1082 acres on December 31, 2003. No soil was salvaged or needs to be replaced beneath the soil stockpile sites. Also, since Pond 005 • (4.8 acres), Pond 006 (7.9 acres), the Mine Entrance Road, Haul Road A, and Haul Road G are permanent postmine facilities (11.2 acres), soil will only be replaced on a portion of those roads effectively narrowing them to 20 feet wide. Topsoil has been replaced on 439.6 acres of disturbed area through December 31, 2003. Therefore, the total disturbance area requiring topsoil as of December 31, 2003 was 704 acres at the mine site and 96.6 acres for the tie-across haul road. Soil Replacement Thickness The soil replacement thickness for the firs[ five-year permit term was projected to be 1.4 feet for the mine area and 0.7 feet for the tie-across haul road. The soil balance as of December 31, 2003 was calculated as follows: Mine area Total disturbance area Permanent Facilities & Topsoil replaced Disturbance azea requiring soil Soil in stockpiles (Table OO.I) Mean replacement depth 1082 acres 439 acres 704 acres 1018.3 acre-feet 1.45 feet Tie Across Haul Road Disturbance area requiring soil 96.6 acres Soil in stockpiles (Table 00.1) 69.7 acre-fee[ Mean replacement depth = 0.7 feet 3
