2.1 GROUND WATER -LEVEL CHANGES <br />2.1.1 SUMMARY <br />Significant mine activities during 2014 included the continued expansion of the K and L <br />pits. Mining in the F pit, which started in 1997, ceased mining in 2011 with only reclamation <br />activities in 2012 through 2014 in this area. Mining was initiated in 2001 in the G pit, which was idle <br />in 2010 through 2014. The K pit was mined in the H, 12, K, LK, L, ML, LL, M, MM, LM, Q and R <br />seams in 2014. L pit mined in seams I2, K, ML, M, MM, LM, Q and R seams in 2014. Dewatering <br />occurred in only the K pit during 2014 with a volume of 31.16 ac -ft pumped. Well dewatering of <br />99.15 ac -ft was produced in 2014 near the G pit. <br />Annual precipitation for 2014 was slightly above normal at 17.91 inches, compared to the <br />Trapper record and long -term record (Figure 2 -1). The 2006, 2007, 2008, 2010 and 2011 <br />precipitation were above normal while the 2012 precipitation is significantly below normal, the 2013 <br />precipitation at normal and the 2014 slightly above normal, relative to the Trapper average since <br />1978 (see Figure 2 -1). The last two years were above, previous year below and the prior six years <br />were significantly above the long -term record average. Recharge in this geographic setting is directly <br />related to precipitation. <br />The effects of natural recharge variations on the respective aquifers can be observed in <br />wells located in undisturbed areas away from the influence of mining activities. Wells GC -2, GC -3 <br />and GP -9 are used to indicate natural response in the past but need to be used with caution starting in <br />2000 due to mining moving into this area. Well GC -3 exhibited the alluvial water -level response <br />with a rise in early 2014 which was followed by a decline in water level. The effects on the 3rd <br />White Sandstone aquifer are observed in wells GC -2 and GP -9. Wells GC -2 and GP -9 show an <br />overall fairly steady water level in 2014 showing minimum affects from the below average <br />precipitation in 2012 and the near and above average precipitation in 2013 and 2014, respectively. <br />Trapper Mining Company 2 -2 <br />2014 Annual Report <br />
