/~ <br />Mr. Dan Bear <br />March 25, 1998 <br />Page 2 <br />/~~/~,\ - <br />r <br />5) Please provide a description of the faults shown on the mine progress map submi«ed with the Bear Mine <br />1996 Annual Hydrology Report. Did these faults exhibit any offset. Were these fault areas moist or did <br />they produce any water inflow? <br />6) Did Bear personnel observe any water inflows or areas of the mine with elevated temperatures? <br />7) Please provide a detailed description of the manner in which water was handled in the Bear No. 3 Mine. <br />Where were water accumulations collected and/or stored. Describe any sump volumes and locations. <br />8) Describe any pipe installations which occurred to handle mine inflows. Did all inflows gravity flow to <br />sumps, pipes or discharge locations? During operations, did all mine inflows collect in sumps, or did <br />some of the water flow to down gradient locations in the mine beyond any possible collection point? <br />Include descriptions of the mechanisms by which water was routed to the NPDES discharge point, and <br />for use in the mine. Include details regarding pump locations, pumping rates and pumping duration. <br />Provide as much detail as possible. <br />9) The December 19, 1997 letter from Dan Bear (response number 29), references a meeting with Mr. Phil <br />Schmidt. The last sentence of response number 29 in the above-referenced letter states "At the time Bear <br />did not know MCC was planning to convert the area above the Bear No. 3 Mine into a huge sump". You <br />have since indicated that during some meeting, Mr. Schmidt informed you that fault inflow waters would <br />be pumped to the NW panels above the Bear Mine. <br />Please describe, in detail, any and all meetings with MCC personnel regarding mine water storage and <br />water inflows, including dates of meetings and your recollection of any information exchanged. <br />Your response to this letter as soon as possible will be appreciated. <br />S}'~ei <br />L_-'~ <br />f <br />~id.Berry <br />S nor Environmental Protection Specialist <br />cc: Susan McCannon, DMG <br />Mike Boulay, DMG <br />Steve Brown, Attorney General Office <br />M:V ISSVRCb.WLETiR.DnB <br />
