SNOWCAP COAL COMPANY <br />2007 ANNUAL HYDROLOGIC REPORT <br />OCTOBER 1, 2006 THROUGH SEPTEMBER 30, 2007 <br />Introduction <br />During the 2007 Water Year, the "Year", the mines were idle. Mining ceased at the Roadside <br />Portals on December 2, 1999. The North Mine was sealed on February 10, 2000. The <br />Roadside South Mine was sealed on April 12, 2000. The South Fan was sealed May 22, 2000. <br />The 2 West Portals were sealed on April 24, 2000. Production at the Roadside North utilized <br />room and pillar mining with a continuous miner and shuttle cars. <br />Reclamation of CRDA-2 was completed in 2002. The sediment retained by the drop structures <br />in Coal Canyon was harvested for cover material. Material excavated during construction of the <br />upper diversion ditch was also used as cover material. A small amount of cover material was <br />obtained from CBA-1. Topsoil was obtained from Topsoil Stockpiles 2, 7, 8 and 9. Reclamation <br />of CRDA-1 was also completed in 2002. Cover material was obtained from CBA-2. The road to <br />CRDA-1 was left open to accept coal and refuse material from other ongoing reclamation <br />activities. The road begins at the west end of Haul Road No. 5 and extends to the top of CRDA- <br />1. <br />The North Portal was regraded to approximate original contour during 2002. Backfill material <br />came from areas filled near Coal Creek and around the coal stockpile area. <br />During 2002 the RSRDA was graded to final contours. The existing cover was graded off of the <br />slope and used as cover below the first bench. Refuse material was cut from the pile to <br />establish two 10' - 15' wide benches on 30' to 40' elevation intervals. This refuse material was <br />placed in an extension of the pile to the north. Cover material was obtained from the RSRDA <br />borrow area. <br />During 2003, a portion of the conveyor corridor was regraded and seeded. This work extended <br />from the culvert under Excel's frontage road to the culvert under the railroad loop. The conveyor <br />bridge over the Colorado River was removed during the year. <br />During 2004, the conveyor corridor, from the Xcel culvert south to Transfer Building #2 and east <br />of Colorado River where conveyor tube crossed river was graded to approximate original <br />contours and reseed. <br />No reclamation was performed in 2005 or 2006. <br />During 2007, a permit revision (PR-3) was approved to change the land use at the South Portal <br />from Fish and Wildlife to Industrial/Commercial. Final grading was completed for the approved <br />reclamation plan. <br />The general format of this report is the same as in previous years. <br />
