Dave Berry <br />December 9, 1997 <br />Page 6 <br />48. Did Bear divert face runoff andlor flows to sealed or previously developed <br />and/or pillared workings? <br />49. Provide data on mine inflows including quantity, quality, location, <br />temperature, and how the water was routed in the mine. Where will water <br />utilized by Bear during its operations accumulate now that the mine is <br />closed? <br />50. What was the flow rate of the inflow at the time of mine closure? <br />51. Has Bear's reclamation plan taken into account past instabilities in and <br />around the Bear Mine site? If so, what are the details of those plans? <br />52. What is believed to be cause of the different chemistry in the AA-1 <br />monitoring well that was located in the alluvium at the west end of the mine <br />site (now covered by slide debris) as compared to well AA-3 (as shown in <br />Bear's 1995 and 1996 AHRs)? How long has Bear been monitoring these <br />wells and how long has this difference in chemistry been observed? <br />53. Bear's AHRs provide mine maps which show a couple of faulted areas. For <br />the fault at the west end of the 3rd west panel, in particular, what information <br />is available on the effects this fault may have on groundwater flow, colluvial <br />inflows, and on communication between the West Elk workings and the Bear <br />mine workings? <br />54. Have you performed any conductivity analyses or otherwise estimated or <br />calculated migration time for water passing through the coal between your <br />B-Seam workings and Mountain Coal's Northwest Panels? Please provide <br />results. <br />Very truly yours, <br />~` ~~~ <br />R. Kirk Mueller <br />RKM:kmn <br />cc: Phil Schmidt, WEM <br />Jon Jones, WWE <br />
