residual water left in the casing. This well is located in a pillar next to the start line for <br />LWB-8. This pillar was developed in September 2006. A substantial decrease in water <br />level was noted following the development work. <br />The water level in Hole 31-7M remained the constant. This well is up gradient from <br />mining activity and the water level fluctuation is minimal. <br />Monitoring Hole 32-7M was plugged in August 2010 to eliminate connection with the <br />sealed off portion of the mine. <br />33-8M experienced a slight rise in water level of 1.3 feet, within the normally expected <br />range of fluctuation. <br />The hydrographs of the 'lower sandstone facies" are designated by the letter "L" following <br />the hole number. <br />Hole 2-17L showed a drop of 11.1 feet from the prior year. This decrease is attributed to <br />the fall in water level within the D -seam workings due to pumping. <br />Hole 4-20L showed a fall of 1.0 feet from the prior year. <br />Monitoring Hole 32-71- was plugged in February 2001 to eliminate connection with the <br />sealed off portion of the mine. <br />Hole 33-81- showed a 0.4 foot rise in the depth to water. This response is similar to the <br />adjacent 33-8M and 33-8U holes. <br />Monitoring hole 22-21- was completed in October 2005 for monitoring future mining <br />expansion. This hole recorded a 109.9 foot drop in head over the prior year. This <br />apparent fluctuation is difficult to explain since the nearest longwall mining is about 3800 <br />feet away. There is a possibility that there is connectivity with development workings in <br />the mains through ancient stream channels. Given that this is a small confined water <br />system small changes can produce great changes in head. Other abrupt changes in <br />water level were observed at this site shortly following its construction (see Appendix D- <br />14). These fluctuations are likely naturally occurring due to unique but unexplained <br />hydrogeologic characteristics unrelated to mining activity. <br />From the baseline data, all three zones should be classified as "aquitards" in that they will <br />yield water but at very slow rates. Mining in the B Seam so far has encountered only <br />small flows of water and the mine is essentially dry. Typical inflows are in the order of 20 <br />to 40 gpm (includes water resulting from leaks, water line brakes, and other similar <br />
