1 <br />SURFACE WATER MONITORING <br />' There are six (6) surface monitoring points within Bear Coal's <br />permitted area. Pond 004, Upper French Drain (FD-U), Lower French <br />Drain (FD-L), Spring G-26A, G-26B, and CR-12. Location of Pond 004 <br />' and French Drains can be found on the map located in Appendix A and <br />Spring location on the map located in Appendix C. Technical <br />revision (TR-23) approved January 16, 1996, requires monitoring of <br />' the North Fork of the Gunnison' River, upstream and downstream, <br />beginning in 1996. <br />' Pond 004 <br />' As a result of heavy precipitation received during the winter <br /> and spring of 1995, pond 004 began discharging in March and <br /> continued in most part through July. Approximately 2,549,000 <br />' gallons (7.80 acre feet) was released during this period. It was <br /> also discovered during this period, that the perimeter ditch <br />' surrounding the Bear #3 Mine was receiving water from the North <br />Fork of the Gunnison River. The North Fork of the Gunnison River <br />at this time was experiencing a high spring run-off and as a result <br />of the ditch's close proximity to the river, water flowed through <br />the alluvium and into the perimeter ditch. As a result, pond 004 <br />saw a considerable increase in water as compared to previous years. <br />' Field parameters for temperature, conductivity and salinity <br />from pond 004 were tested by a YSI (Yellow Springs Instrument) <br />Model No. 33. The pH levels were taken using a Oakton pHTestr2, <br />' Model No. 35624-20 meter. A portable v-notch weir was used to <br />determine flow. All other parameters were determined by collecting <br />samples in precharged bottles and submitting them to ACZ <br />' Laboratories. Laboratory results for the 1995 discharge from <br />outfall 004 are presented in Appendix D. <br />' Discharge Monitoring Reports (OMB's) for outfall 004 were <br />filed as required. <br />1 <br /> <br /> <br />1 <br />
