water level changes are thought to be showing natural responses but could be influenced by the <br />mining that is greater than 1900 feet away. <br />Well GP -2 (Figure A -8) is located in a previously undisturbed area near the eastern <br />boundary of the PA. Water levels rose in 2008 through 2011 in well GP -2 to a similar level as <br />existed prior to 1999. A large decline in water levels started in 1999. A smaller decline occurred in <br />2012 through 2014, which is likely due to less recharge. <br />Wells GP -3 and GP -4 are less than 1000 feet downgradient from A pit. Both are flowing <br />wells completed in the M and KLM aquifers, respectively. Water levels in these two wells had <br />shown similar responses in water levels due to changes in precipitation but the 2005 through 2011 <br />water level changes were different (see Figures A -9 and A -10). Water levels in well GP -3 have <br />recovered to above pre-mine levels in this area and show that any depletion of water from upgradient <br />mining has been replaced by recharge to the HI aquifer. The overall gradual declines in water levels <br />in well GP -3 in the years just prior to 2005 are probably a function of below normal precipitation <br />during this period. The water level in well GP4 has also recovered to pre -mine levels but observed <br />variable levels in 2004 through 2014. The decline in the fourth quarter is similar to other large <br />declines observed in this well. <br />Well GNP -1 (Figure A -9) is completed in the HI aquifer to monitor ground -water <br />conditions downgradient of the ash disposal site immediately south in A pit. Water levels became <br />steady in 2001 and stayed fairly steady for the next six years with a small increase in 2006 through <br />2011. A very gradual decline was observed in 2012 through 2014. <br />Figure A -10 also presents water levels for the well COY (alluvium). Water levels at the <br />COY well started to decline in 2009 and 2010 after seven years of overall rising. Overall water levels <br />rose in 2011 but overall declined in 2012 and were overall fairly steady in 2013 and 2014. The <br />Trapper Mining Company 2-7 <br />2014 Annual Report <br />
