2003 Annual Hydrologic Report Page 3 <br />section and are accessible throughout the year. The intermittent flow in Jerry Creek is <br />measured at the culvert near the Highline Canal, SWGS 08. Beginning July 1999, <br />instantaneous flows are to be monitored monthly. Data taken during the Year are listed <br />on data pages SR-2 for Coal Canyon and SS-2 for Jerry Creek. <br />There were three seeps included in the hydrologic monitoring in 1995. The location of the <br />seeps are shown on the Hydrologic Monitoring Map. They are located adjacent to Coal <br />Canyon drainage and Jerry Creek. They are primarily evident by the white staining on the <br />hillsides from evaporation of the seeps. None of them flow to the creek channel but <br />generally evaporate within a couple of hundred feet of the source. On May 14, 2003 the <br />springs were damp to dry. The monitoring results to date are shown on data page ST-1. <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 <br />to allow pumping water from the south end of the Roadside South Portal out the 2 West <br />portals. Discharge point 016 is permitted for gravity discharge from the northwest intake <br />pool. It replaced outfalls 001 and 002 on March 3i, 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 <br />was installed from the No.2 South Mains sump to outfall 001. The routing of this 4-inch <br />diameter pipe is presented on permit Figure 14-6. The capacity of this discharge pipe is <br />about 75 gpm. 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 <br />plant was shut down during December 1999 so al; mine i; .flovds in excess of those handled <br />by outfall 001, flow north to the lower portion of the mine where they were handled by the <br />siphon, outfall 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 />Rev. 03/17/04 <br />
