• Pond 004: <br />Field parameters for temperature, conductivity and salinity form pond 004 <br />were tested by a YSI (Yellow Springs Instrument) Model No. 33. The pH levels <br />were taken using a Oakton pHTestr2, Model No. 35624-20 meter. A portable v- <br />notch weir was used to determine flow. All other pazameters were determined by <br />collecting samples in prechazged bottles and submitting them to ACZ Laboratories. <br />Laboratory results for the 1996 dischazge season are presented in Appendix C. <br />Typically, Pond 004 collects spring snow melt and precipitation azound the <br />Bear Mine property and dischazges it into the North Fork River. However, because <br />of the March 1996 slide, pond 004 also collected drainage from the slide area. <br />A review of field data for 1996 shows that Pond 004 dischazged into the river <br />only 3 months -Mazch, April, and May. During this period, approximately <br />2,201,760 gallons (6.74 acre feet) of runoff was released into the North fork of the <br />Gunnison River. The North Fork of the Gunnison River during this reporting <br />period experienced a high, spring run-off, and as a result of the ditch's close <br />proximity to the river, water flowed through the alluvium and into the perimeter <br />ditch. <br />Discharge Monitoring Reports (DNB's) for Pond 004 were filed as required. <br /> <br />French Drains• <br />As previously mentioned, Bear Coal Company experienced a massive land <br />slide beginning during the month of Mazch. This slide destroyed a major portion of <br />the access road to the portal bench as well as both French Drains. As a result of <br />this slide, Bear Coal Company attempted to monitor the seepage which came out of <br />the same approximate azeas as the drains. To denote these changes in the <br />monitoring locations, which began in April, this report will refer to the drain <br />locations as "French Drain -upper slide (FD-US)" and "French Drain -lower slide <br />(FD-LS)." Refer to Appendix A for French Drain Location. <br />• -5- <br />
