('red <br />Only one monitoring well does not provide relevant or useful water quality information as <br />detailed in the original plan. Well 20-4A has been removed from the water quality monitoring <br />program for both the tentporai_~' suspeiasic)r) and conunercicr! mining ~roc(rrctrnn operating modes. <br />The well was originally drilled as a B Groove monitoring point but did not produce sufficient <br />water. It was cemented and the casing was perforated at the A Groove; however, even during the <br />baseline period, the data indicated evidence of localized cement contamination in the perforated <br />cone which causes interference and makes water quality data from this point difticult to evaluate <br />in relation to the mining activity. Although water quality data is not relevant from this point, <br />water level data will continue to be collected from well 20-4A. <br />A map of the layout of the ground water monitoring wells is provided in Figure 1 below. <br />FINAL: Modification No. 9, UIC Area Pernlit No. 0030858-00000 <br />Page 24 of 46 <br />
