2007 AHR Page3 <br />There were four seeps included in the hydrologic monitoring in 1995. The locations of the <br />seeps are shown on the Hydrologic Monitoring Map. They are located adjacent to Coal Canyon <br />drainage and Jerry Creek. They are primarily evident by the white staining on the hillsides from <br />evaporation of the seeps. None of them flow to the creek channel but generally evaporate <br />within a couple of hundred feet of the source. On April 19, 2006, Snowcap Coal Company <br />submitted a technical revision, TR50, requesting to discontinue seep monitoring. The request <br />was approved by the Division on July 25, 2006. Therefore, no monitoring was performed during <br />the Year. <br />There was no discharge from CDPS discharge points 005 thru 015 during the Year. These <br />outfalls cover sediment pond discharges. Discharge point 015, now inactive, was permitted to <br />allow pumping water from the south end of the Roadside South Portal out the 2 West portals. <br />Discharge point 016 is permitted for gravity discharge from the northwest intake pool. It <br />replaced outfalls 001 and 002 on March 31, 2002. <br />Discharge point 001 was primarily used as an overflow to a mine water system for the <br />preparation plant during mine operations. During March and April 2000; a discharge pipe was <br />installed from the No.2 South Mains sump to outfall 001. The routing of this 4-inch diameter <br />pipe is presented on permit Figure 14-6. The capacity of this discharge pipe is about 75 gpm. <br />Flow ceased at discharge point 001 on March 31, 2002. <br />Discharge point 002 was water siphoned from the reclaimed Northwest Intake Portal at the <br />Roadside South Portals. Mine inflows that were not pumped to the preparation plant were <br />routed to an abandoned portion of the mine for discharge from this point. The preparation plant <br />was shut down during December 1999 so all mine inflows in excess of those handled by outfall <br />001, flow north to the lower portion of the mine where they were handled by the siphon, outfall <br />002. Flow ceased at discharge point 002 on March 31, 2002. <br />The following table presents the total dissolved solids concentration in Outfall 002. <br />Average TDS from Pages SE-8 -~ SE-11 Outfall 002 <br />Water Year 1999 2000 2001 2002 <br />TDS (mg/I) 1558 1560 1500 1500 <br />Discharge point 016 was put into service April 1, 2002. Discharge began April 3, 2002. This <br />gravity discharge point handles all of the water that flows into the sealed South Portal. Since it <br />is a gravity discharge point, the flow discharged will equal the flow into the mine. Table M07-1 <br />presents a summary of the monthly flow from the mine. Data page SV-6 presents a listing of <br />flow and water quality monitoring performed at this site during the Year. Data page SU-3 <br />includes a full suite analysis performed on a sample collected during the Year. The average <br />
