Bowie Resources Limited Bowie No. 2 Mine 1998 Annual Hydrology Report Table 5 contains local precipitation data for 1998. This data is obtained from the Internet at www.crh.noaa.gov/gjt. Flow data for the North Fork of the Gunnison river is obtained from the USGS from a website http://www.nwis-colo.cr.usgs.gov/historic.html. This flow readmg is obtained telemetrically from a station near Somerset, CO and is reflective of upper river flows only. This monitoring point is identified by the USGS as 09132500. Monitoring point identifiers within the permit boundary aze historic and follow no specific naming convention. Monitoring points located in azeas mon;toried for future permit revisions follow a convention where the first letter(s) designates a water source type, such as "S" for Spring or "SP" for Spring and Pond. The numeral(s) following the first letter designate what Sectioa the water source is located, for instance, SP34-2 would be a spring and pond in Section 34. The numeral separated with a dash indicates an index number for that point. SP34-2 would be the second monitoring point found in Section 34. NPDES Monitoring Points The mine has three (3) discharge monitoring points. All three points were monitored according to permit requirements during periods of discharge. Copies of the Dischazge Monitoring . Reports (OMB's) and the analysis of the discharged waters which has been provided to the Colorado Department of heahh (CDOH) and Environmental Protection Agencies aze available for review at the minesite. North Fork Alluvium Monitoring Wells Alluvial monitoring wells AW-1 through AW-6 aze located near the mine entrance along Old State Highway 133. These wells aze monitored quarterly for field parameters and sem%annually for full suite laboratory parameters during the second and fourth quarters in accordance with the permit application. The 1998 sampling season provides resuhs consistent with baseline information provided in the permit application, showing no adverse impact to groundwater during the construction of the mine. Surface Water Monitoring Stations: PONDS Stock Ponds P-1 through P-5 are monitored quarterly for 1.) Inflow; 2.) Outflow; and 3.) Water level below spillway outlet or depth of water in the pond measured from the bottom of the pond. Field data collected during the 1998 sampling season is consistent with baseline information provided in the permit application. Three additional ponds aze being monitored in order to gather baseline information for a future permit revision. Pape 2
