The "upper sandstone facies" holes are designated by a name ending in "U ". <br />There are three upper facies holes with water (22 -3U, 29 -4U and 33 -8U). 22 -3U is a <br />newer hole constructed in the fourth quarter of 2005 for baseline and monitoring purposes <br />of future mining activities. Water levels in this well appeared stable over the past year <br />with an indicated rise of only 0.3 feet. Data for this well and other wells are shown in <br />Appendix C. <br />The water level in 29 -4U rose by 3.6 feet this year following a large drop in water level <br />from the prior year (62.5 feet). The prior year's decrease was a result of the longwall <br />passing within 300 feet of this hole. It has since stabilized but the longwall will subside <br />this hole in early 2013. <br />Well 33 -8U was obstructed by a dead rodent at 211.9 feet. This obstruction will most <br />likely decompose allowing future measurements. Historically the changes in the water <br />level for this hole closely mimicked those of 33 -8M and 33 -8L which have remained <br />relatively stable. <br />The middle "siltstone -coal fades" 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 />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 since 2007. The flow rate <br />has reduced from 150 ml/minute in 2010 to 52 ml /minute in 2011, and was down to 13.5 <br />ml /minute in 2012. <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 />has generally decreased since 1988 with a slight rise of 1.3 feet since the last monitoring <br />period. <br />Water level in monitoring hole 29 -4M was essentially stable with a slight drop of 0.2 feet <br />from the prior year. <br />6 <br />
