Bowie Resources Limited <br />Bowie No. 2 Mine <br />• 1999 Annual Hydrology Report <br />Table 5 contains local precipitation data for 1999. This data is obtained from the intemet at <br />www.crh.noaa.gov/gj t. <br />Table 6 contains a listing of monitoring point charts. Points without charts either have <br />insufficient monitoring events or have little evidence of water. <br />Monitoring point tables and charts follow this introduction. Each Monitoring Point has an <br />individual table which tabulates the annual data collection and reports Minimum, Maximum, <br />Average and Baseline data. A reference in each footnote explains the period used for baseline <br />data. <br />Flow data for the North Fork of the Gunnison river is obtained from the USGS from a website <br />http://nwis-colo.cr.usgs.gov/historic.html. This flow reading is obtained telemetrically from a <br />station neaz Somerset, CO and is reflective of upper river flows only. This monitoring point is <br />identified by the USGS as 09132500. <br />Monitoring point identifiers within the permit boundary are historic and follow no specific <br />naming convention. Monitoring points located in areas monitoried for future permit revisions <br />follow a convention where the first letter(s) designates a water source type, such as "S" for <br />• Spring or "SP" for Spring and Pond. The numeral(s) following the firs[ letter designate what <br />Section the water source is located, for instance, SP34-2 would be a spring and pond in Section <br />34. The numeral separated with a dash indicates an index number for that point. SP34-2 would <br />be the second monitoring point found in Section 34. <br />NPDES Monitoring Points <br />The mine has three (3) discharge monitoring points. All three points were monitored according <br />to permit requirements during periods of discharge. Copies of the Discharge Monitoring <br />Reports (DNB's) and the analysis of the discharged waters which has been provided to the <br />Colorado Department of health (CDOH) and Environmental Protection Agencies are available <br />for review at the minesite. <br />North Fork Alluvium Monitoring Wells <br />Alluvial monitoring wells AW-1 through AW-6 are located near the mine entrance along the <br />north side of Old State Highway 133. These wells are monitored quarterly for field parameters <br />and semi-annually for full suite laboratory parameters during the second and fourth quarters in <br />accordance with the permit application. Alluvial monitoring wells AW-7 through AW-10 aze <br />located near the mine entrance along the south side of Old State Highway 133. These wells <br />were installed as a requirement of PR-03 which allows the mine operator to relocate Sediment <br />Pond B to the south side of the highway. The 1999 sampling season provides results consistent <br />. with baseline information provided in the permit application, showing no adverse impact to <br />groundwater during the construction of the mine. <br />Page 2 <br />
