• SNOWCAP COAL COMPANY <br />2002 ANNUAL HYDROLOGIC REPORT <br />OCTOBER 1, 2001 THROUGH SEPTEMBER 30, 2002 <br />Introduction <br />During the 2002 Water Year, the "Year", the mines were idle. Mining ceased at the <br />Roadside Portals on December 2, 1999. The North Mine was sealed on February 10, <br />2000. The Roadside South Mine was sealed on April 12, 2000. The South Fan was <br />sealed May 22, 2000. The 2 West Portals were sealed on April 24, 2000. Production at <br />the Roadside North utilized room and pillar mining with a continuous miner and shuttle <br />cars. <br />Reclamation of CRDA-2 was completed in 2002. The sediment retained by the drop <br />structures in Coal Canyon was harvested for cover material. Material excavated during <br />construction of the upper diversion ditch was also used as cover material. A small amount <br />of cover material was obtained from CBA-1. Topsoil was obtained from Topsoil Stockpiles <br />2, 7, 8 and 9. Reclamation of CRDA-1 was also completed in 2002. Cover material was <br />• obtained from CBA-2. The road to CRDA-1 was left open to accept coal and refuse <br />material from otherongoing reclamation activities. The road begins atthe west end of Haul <br />Road No. 5 and extends to the top of CRDA-1. <br />The North Portal was regraded to approximate original contour during 2002. Backfill <br />material 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 <br />of the slope and used as cover below the first bench. Refuse material was cut from the <br />pile to establish two 10' - 15' wide benches on 30' to 40' elevation intervals. This refuse <br />material was placed in an extension of the pile to the north. Cover material was obtained <br />from the RSRDA borrow area. <br />The Year was unusually dry. Precipitation at the Palisade, CO weather station (056266) <br />totaled 7.03 inches compared to an annual average of 9.93 inches. Snowpack on the <br />Upper Colorado River Basin was 71 % of normal through March 2002. <br />The general format of this report is the same as in previous years. <br /> <br />
