In the <br />past we have talked and communicated with your Division about the MWNW monitoring well, and we would <br />like to clarify our position on this issue. We have carefully studied the implications of the MWNW current <br />status. We believo that the two water injection tests sufficiently demonstrate that this well will provide <br />sufficient monitoring capability for the presence or absence of water in the mine void. The basis for that <br />statement is that the approximate twenty feet of the partial obstruction above the mine floor is probably <br />insignificant when compared with over a thousand feet of mine floor elevation difference from the deepest to the <br />highest part of the mine. We want to stress that point because the mine void pitches and is not close to being <br />in a horizontal plane. In addition it is completely unknown how the many mine and panel seals will affect water <br />levels in different parts of the mine. We want to go on record to suggest that EFCI be allowed to monitor the <br />MWNW at the point above the obstruction. <br />Doug Corley, Pres. <br />The Corley Company <br />https: / /mail.g oog le.conVmai I /u /0 / ?ui =2 &i Ire29129fcb5 &\iev�-- pt &search =i nbox&th= 146f972ee2948b94 &si ml= 146f972ee2948b94 1 /1 <br />
