6 <br /> <br /> <br />There is one upper facies hole with water (22-3U). 22-3U is a newer hole constructed in <br />the fourth quarter of 2005 for baseline and monitoring purposes of future mining activities. <br />Water levels in this well appeared stable over the past year with an indicated rise of 0.7 <br />feet. Data for this well and other wells are shown in Appendix C. <br /> <br />Well 29-4U was subsided in early 2013. A blockage resulted at 309.2 feet. It is expected <br />that this well would have reported as being dry even if no blockage had occurred. <br /> <br />Well 32-7U remains dry following longwall subsidence in mining near the hole in <br />1999/2000 and subsiding it in 2001. <br /> <br />The water level in 33-8U rose 1.2 feet from the prior year. This rise follows an annual <br />drop of 1.3 feet indicating this well may have stabilized and the change may be natural <br />fluctuations. The water levels of 33-8U, 8M, and 8L appear to have similar fluctuations <br />indicating communications between zones. <br /> <br />The middle "siltstone-coal facies" monitoring holes are designated by an "M" following the <br />hole number. These monitor holes are open through the interval containing the D Seam <br />and B Seam. <br /> <br />Monitoring hole 22-3M was drilled in November 2006 and is now the ‘point of compliance’. <br />Depth to water data is included in Appendix D and annual qualitative data presented in <br />Appendix C. This hole has exhibited a very slow artesian flow from 2007 through 2012. <br />The flow rate ranged from 150 ml/minute in 2010 to 13.2 ml/minute in 2012. The artesian <br />flow has stopped and the water level dropped to 24.1 feet, 6.0 feet lower than last year. <br /> <br />Monitor hole TW2-17M was surrounded by mining first in November 1985 but was not <br />intercepted in the workings. It is apparently located in a pillar completely surrounded by <br />open workings. At that time it showed virtually no response to development mining. In <br />February 1988 longwall panel 1 was mined to within about 900 feet of this hole. <br />Obviously, longwall mining disrupts the mined zone more than development mining, and <br />the water level in TW2-17M did show a response to mining at that time. The water level <br />generally decreased since 1988 with a rise of 1.6 feet since the last monitoring period. <br />This rise may be associated with the long term rising waterline within the D-seam <br />workings. <br /> <br />Monitoring Hole 29-4M was plugged in November 2012 to eliminate connection with the <br />sealed off portion of the mine. <br />
