- DEC 09 'y7 12~09PM RRCO C6RL CC' DEN'. ER <br />Dave Berry <br />December 9, 1997 <br />Page 5 <br />36. Provide surveyed location of Bear C-Seam portal and Edwards Beam <br />portal. <br />37. Provide location and elevation of the base of the reclaim structure and the <br />sump under the surge or reclaim coal pile. <br />38. Describe timing, quantity and chemipl composftion of water pumped from <br />the sump under the reclaim tunnel. <br />39. When and where was the current slide movement first noticed? How has <br />the slide changed over time? Do you have notes or photographs that can <br />be shared with us? <br />40. When and why did the slump occur that e~osed the outflow from the <br />- Edwards portal? What are the weathered concrete and steel materials <br />associated with? <br />41. Provide logtion, elevation and data from any slope stability movements in <br />the vicinity of the Bear Mine facility. <br />42. Please provide copies of any aerial photographs or photogrametric maps <br />taken and/or constructed in the last 4 years. <br />43. When was the redamation of the coal reclaim conveyor and ventilation <br />tunnel started and completed? Where did the material come from to baddill <br />the reclaim and veniilation tunnels? How was this water handled when <br />reclaiming the reclaim tunnel and vent? How were these inflows sealed at <br />recamation? <br />44. When was water first observed in the reclaim and vent tunnels? How has <br />this water been handled? Please provide historic flows, field parameters <br />and chemistry. <br />P. C; 7 <br />45. Please provide an accurate (surveyed) map of all of the Bear No. 3 Mine <br />` portals, main entries, and outby facilities (stack tube, reclaim tunnel, reclaim <br />vent, etc.), along with the Edwards portals, main entries and outby facilities - <br />including elevations and coordinates. <br />46. Please provide a detailed plan view and cross-section(s) of the reclamation <br />plan, along with surface ownership. <br />47. Has there ever been or is there a clear water diversion ditch or drainage or <br />sediment control ditch in the vicinity of the slide? ff so, has there been any <br />water flow observed? ff so, what measurements ar chemistry are available? <br />
