• SENECA II-W MINE <br />2009 ANNUAL RECLAMATION REPORT <br />2009 DISTURBANCE AREA <br />There were no additional acres disturbed during 2009. The total disturbance is 1,381.9 acres. This acreage is <br />reflected on the CDRMS Annual Report Form and is discussed in the text of the following report. The <br />attached 2009 Reclamation maps portray the physical disturbance boundaries but do not include or show the <br />96.6 acres associated with the Tie-Across Haul Road. <br />BACKFILLING AND GRADING <br />There were 0.8 acres graded in 2009. <br />TOPSOIL AND SPOIL MONITORING <br />SCC is required by Permit C-82-057 to monitor the salvage, storage, and redistribution of topsoil and spoil <br />handling operations at the Seneca II-W Mine. Only 0.8 acres of backfilling/grading (topsoil stockpiles and <br />the small area by shop fuel tank storage) and 0.0 acres of topsoil replacement were conducted during 2009, <br />therefore no monitoring was conducted. <br />• Topsoil Recovery Documentation <br />There was no additional topsoil recovered during 2009. <br />• 0 2009 Topsoil Replacement Thickness <br />There was no topsoil replaced; therefore no topsoil thickness samples were collected in 2009. <br />• Soil Pit - Topsoil Fertility/Spoil Suitability <br />No topsoil fertility or spoil suitability samples were collected in 2009. <br />• Topsoil Balance <br />SCC submitted a topsoil balance with permit Revision 04 (dated 9/04). The topsoil balance has not been <br />revised since Seneca II-W is reclaimed except for roads and facilities areas. <br />Topsoil Salvage and Storage. No topsoil was salvaged during 2009. The life-of-mine disturbance from <br />which topsoil was salvaged (1,381.9 acres) and the topsoil stockpile sites as of December 31, 2009 are shown <br />the 2009 Topsoil Replacement map. <br />The remaining stockpile volumes as of December 31, 2009 are listed in Table 09.1, Topsoil Stockpile <br />Volumes. As of the end of 2009, 75.5 acre-feet of topsoil remain stockpiled in the mining area and 73.1 acre- <br />feet of topsoil are stockpiled along the Tie-Across Haul Road. <br />Topsoil Replacement. No topsoil was replaced during 2009. Therefore, the total remaining mine <br />disturbance area requiring topsoil (as of December 31, 2009) is 84.1 acres. <br />• Topsoil Replacement Thickness. The overall topsoil replacement thickness for the II-W disturbed area <br />was originally projected to be 1.3 feet for the mine area and 0.7 feet for the Tie-Across Haul Road. The <br />topsoil balance for the remaining disturbed was calculated as follows:
