1992, 1993, 1994 AHR Review <br />Bear Coal Company <br />March 30, 1995 (Revised) <br />Page 6 <br />does not monitor the North Fork? The operator should propose <br />an upstream and downstream sampling location to collect <br />quality and quantity data on a regular basis. <br />3. Page 7 of the Findings Document dated April 29, 1994 states <br />that there are several domestic wells located along the river <br />in alluvial material. Please have the operator specify where <br />these wells are located so the Division can determine if there <br />is a possibility the wells could be impacted. The location of <br />these wells should also be included in the permit. <br />4. In the Findings Document referenced above, the Division <br />predicts there will be no degradation of water quality in the <br />alluvial aquifer. This discussion begins on page 19. Based <br />on the monitoring data collected and the calculations provided <br />in BCC's permit, which predicts some impact to the alluvium, <br />I recommend that this section of the Findings Document be <br />revised to calculate more accurately the amount of dilution in <br />the alluvium and the potential for negative impacts. <br />5. As the depth to water in the alluvial wells is taken from the <br />top of the well to the top of the water, the operator should <br />provide the amount of casing above ground and the total depth <br />of the well. I was unable to locate well completion diagrams <br />for the alluvial wells, which the operator should provide as <br />well. <br />6. The operator should provide a short narration or mine map <br />detailing where mining occurred during the AHR reporting <br />period, so that the Division may correlate any potential <br />impacts with mining in the area. <br />7. Units should be included on the Alluvial Well Monitoring Field <br />Data table and the French Drain - Upper table. <br />This concludes my review of the 1992, 1993, and 1994 AHR for the <br />Bear Mine. If there are significant misses in the sampling program <br />and they cannot be explained, then enforcement may follow. Please <br />let me know if you have any questions or require anything further. <br />cc: David Berry <br />CEJ/033AHR93.1 <br />
