MEMO <br />To: David Berry <br />From: Kent Gorham ~~ <br />Subject: Water monito port, Golden Eagle Mine, #C-81-013 <br />Date: February 24, 2004 <br />As per your request, please find attached a report describing the water monitoring and water <br />resources near at the Golden Eagle mine as they re-ate to the NW-1 ventilation shaft. <br />I did some research on the timing of the establishment of the bedrock water monitoring in the <br />vicinity of the mine. A staff member noted on the cover letter for the 1991 Annual Hydrology <br />Report (received 3/17/1992) "For as much water as they produce, they should probably have <br />bedrock wells). Obviously, at that time, the mine did not monitor ground water with the <br />exception of alluvial ground water in the immediate mine vicinity. Further review in conjunction <br />with the 1992 AHR and the Permit Renewal No. 2 ultimately led to the mine converting a <br />number of coal exploration boreholes into water monitoring wells, namely NM-20, NM-21, NM- <br />22, NM-23, SF-1, and SF-2. Closure of the mine resulted in monitoring of three of the major <br />ventilation shafts, GEM-1, GEM-2, and GEM-3. Since mine closure, bedrock water monitoring <br />has been modified slightly, mostly by reducing the monitoring frequency and eliminating wells <br />that provided questionable data or fell into disrepair, resulting in the plan as approved today. <br />The bottom line is that bedrock monitoring began in 1994 and continues today. Let me know if <br />you have more questions. Thanks. <br />CC: Dan Hernandez <br />
