All responses have been accepted <br />by the Division unless otherwise stated below. <br />1. The Division is required to ensure that the hydrologic <br />monitoring program is at all times appropriate and provides <br />data which allows us to accurately assess whether or not <br />impacts are occurring or developing due to mining. Successful <br />completion of this task requires that the monitoring be <br />conducted at all times as specified in the approved monitoring <br />program. Your continued cooperation toward this effort is <br />appreciated. <br />2. In addition to field verification that wells and monitoring <br />stations are kept in working and functional order, we need <br />some assurance that when wells or stations are originally <br />established that they are, to the best of our ability to <br />determine, representative of the conditions and properties for <br />which they were designed to monitor. This is the reason that <br />we ask for the completion information for each monitoring well <br />to be provided to the Division after completion. Water well <br />information does not meet the requirements for <br />confidentiality, and furthermore, the Division is allowed to <br />see all information, even confidential information. It is <br />only the public who is precluded from access to confidential <br />information. <br />The Division's interest in the completion information is <br />simply to have available specific information such as total <br />well depth, casing diameter, top of casing elevation, <br />
