SURFACE WATER MONITORING <br />There are eight (8) surface monitoring points within Bear Coal's permitted <br />area. Pond 004, Upper French Drain (FD-U), Lower French Drain (FD-L), <br />Upstream North Fork (U/S NFG), Downstream North Fork (D/S NFG), Spring G- <br />26A, G-26B and CR- 12. Location of Pond 004, French Drains and NFG's can be <br />found on map "Figure 11" located in Appendix A and spring locations on map <br />"Geology/Hydrology" also located in Appendix A. <br />In the field, a Yellow Springs Instrument (YSI) Model No. 33 was used to <br />measure water temperature, conductivity and salinity. Tlie pH levels were taken <br />using an Oakton pHTestr2, Model No. 35624-20 meter. All other parameters were <br />determined by collecting samples in precharged bottles and submitting them to <br />ACZ Laboratories, Inc., in Steamboat Springs, Colorado, for analysis. The results <br />of groundwater data collected during 1996 and pertinent water quality parameters <br />are found below. <br />It should be noted that on March 30 and 3l of 1996, a landslide occurred <br />above the access road which extended vertically to the North Fork of the Gunnison <br />River. The slide also extended horizontally from the ventilation fan on the west <br />into the ephemeral drainage east of the mine access road switch back. This <br />massive slide destroyed the portal access road drainage system and the slope <br />drainage monitoring system which included the upper french drain (FD-U) and the <br />lower french drain (FD-L). In an investigation by J. E. Stover & Associates of <br />Grand Junction, Colorado, the cause of the slide could be attributed to water from <br />either snow melt and spring precipitation or other sources of ground water yet to <br />be identified. <br />Because the portal access road drainage system was destroyed, drainage <br />was routed to the sediment pond where possible, and alternate sediment controls <br />were installed in areas where drainage could not be directed to the sediment pond. <br />Straw bales were placed along the lower slope of the portal access road to provide <br />alternative sediment control. <br />-4- 4/98 <br />
