Mid-Term Review <br /> Coal Basin Mines <br /> C-017-81 <br /> Introduction <br /> This document presents the results of the Division's mid-term review of <br /> Mid-Continent Resources, Inc. 's, Coal Basin Mines. This mid-term review was <br /> conducted to fulfill the requirements of Rules 2.08.3, 2.06.2(9), 2.06.3(4), <br /> 2.06.5(3) , 2.06.5(3) , 2.06.7(5) and 3.02.2(4). <br /> Rule 2.08.3 requires that the Division conduct a review of each permit issued, <br /> prior to its mid-term (2-1/2 years). Based on this review, for good cause <br /> shown, the Division may require reasonable revision or modification of the <br /> permit provisions to ensure compliance with the Act and Regulations. <br /> Rules 2.06.2, 2.06.3, 2.06. 5 and 2.06.7 require that experimental practices, <br /> mountaintop removal variances, variances from AOC, and variances from <br /> contemporaneous reclamation be reviewed by the Division where applicable <br /> during the mid-term review. The Coal Basin Mines permit contains an approved <br /> request for a variance from AOC based upon steep slope conditions. Rules <br /> 2.06.2, 2.06.3 and 2.06. 7 are not applicable to the Coal Basin mining <br /> operation. Rule 3.02.2(4) requires that the Division review the amount of the <br /> bond and the terms of acceptance of the bond every 2-1/2 years. <br /> This mid-term review consisted of a detailed review of the Coal Basin Mines <br /> application to identify any items that may have been overlooked during the <br /> initial review. The Division also reviewed all subsequent revisions and <br /> stipulation responses to ensure that all permit commitments and conditions <br /> were being followed. 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 also considered. <br /> Section I - Comments <br /> The Coal Basin Mines permit was issued on May 31 , 1983. Numerous Technical <br /> and Minor Revisions have been approved to the permit since issuance. One <br /> permit revision was approved for a new refuse disposal area with a revised <br /> findings document drafted in August, 1984. Another permit revision is in the <br /> review process entailing extension of the permit boundary to include the <br /> life-of-mine area. At present, surface disturbance at the mine is 432 acres. <br /> There are five underground mines at Coal Basin, three of which are presently <br /> inactive.
