Drilling and Abandonment Information Required to be Submitted to the Field Office Manager <br />One copy of the following must be submitted within 30 days after each calendar year: <br />1. Lithologic and geophysical logs and any other required logs of strata penetrated and conditions encountered <br />appropriately identified by the hole number. <br />2. Analyses of coal and other pertinent tests appropriately identified by drill hole number. Identify types of tests <br />that were run (proximate, ultimate, moisture-mineral-matter free basis, etc), and whether the reported results were <br />analyzed or calculated as composite or incremental samples. <br />3. Drill hole location map showing lease or license boundary, coal crop lines, drill hole numbers, and township, <br />ranee and section lines and numbers. <br />4. List of drill hole numbers and depths drilled. <br />B. An abandonment report must be submitted after the drill holes have been properly conditioned for abandonment or if <br />approved in advance, converted to monitoring wells. The report should contain the following: <br />1. For abandoned holes, describe or illustrate the method by which each hole was plugged and conditioned for final <br />abandonment. <br />2. For holes converted to monitoring wells, describe or illustrate the well completion method (cementing, casing set, <br />perforation interval, etc.), what aquifer(s) is being monitored, duration and frequency of monitoring, and types of tests <br />planned (pH, conductivity, pump, cation, etc.) <br />3. Status of reclamation of all disturbed areas. <br />4. List of hole numbers and depths drilled. <br />C. Abandonment inspections will be conducted upon completion of operations to determine if drill holes are properly <br />plugged and disturbed areas are reclaimed. Once the Field Office Manager determines that the holes are adequately <br />plugged and conditioned for abandonment and reclamation is acceptable, final abandonment approval will be given by <br />the Field Office Manager. <br />For drill holes converted to monitoring wells, inspections will be made to determine if the wells are properly <br />completed, drill sites are reclaimed, and access roads are properly water-barred or otherwise maintained to minimize <br />erosion. <br />The following shall be submitted within one year after the completion of drilling operations: <br />1. Any coal reserve base, minable reserve base or recoverable coal reserves estimates generated from the <br />exploration license. <br />ITEM B
