Hydrologic monitoring data was reviewed in conjunction <br />with the review of the application to assess the adequacy of the monitoring <br />plan and discussion of hydrologic impacts. Problems and observations from <br />past inspection reports were considered while conducting the review. <br />This document is organized as follows: Part 1 describes revisions received <br />during the past two-and-a-half years and their implications to the operation, <br />Part 2 presents a summary of the status of the stipulations. Part 3 includes <br />a listing by category of items which need to be revised and a rationale for <br />requiring these revisions. A bond review will be forthcoming following the <br />responses to Part 3. The responses to items identified in Part 3 should be <br />submitted as one package in a format that allows easy insertion into the <br />application by December 14, 1987, <br />Part 1 - Revisions to the Permit <br />Twentymile Coal Company has submitted three revisions during the permit <br />period: A minor revision which concerned surface facility modifications and <br />the disposal of non-coal waste, a technical revision which modified Pond E and <br />a technical revision which modified the hydrologic monitoring plan, The minor <br />revision permitted the disposal of non-coal waste in the Foidel Creek Mine <br />waste rock pit, provided that metal materials were disposed above the water <br />
