Keenesburg Strip Mine (C-1981-028) MT-07 <br /> <br /> <br />Page 1 <br /> <br /> <br /> <br /> <br /> <br />Introduction <br /> <br />This document presents the results of the Midterm Review of the Keenesburg Strip Mine permit, conducted <br />by the Colorado Division of Reclamation, Mining and Safety (Division). The Keenesburg Strip Mine is <br />owned and operated by Coors Energy Company (CEC). This Midterm Review was conducted to fulfill <br />the requirements of the Colorado Surface Coal Mining Reclamation Act (Act), and Rules 2.08.3, 2.06.2(9), <br />2.06.3(4), 2.06.5(3), 2.06.7(5), and 3.02.2(4) of the Rules and Regulations of the Colorado Mined Land <br />Reclamation Board for Coal Mining (Rules), which were promulgated to implement the Act. <br /> <br />Rule 2.08.3 requires that the Division conduct a review of each permit issued not later than the middle of <br />the permit term. Based on this review, for good cause shown, the Division may require reasonable revisions <br />to, or modifications of, the permit provisions to ensure compliance with the Act and Regulations. <br /> <br />Rules 2.06.2, 2.06.3, 2.06.5, and 2.06.7 require that during the midterm review, where applicable, <br />experimental practices, mountaintop removal variances, variances from approximate original contour <br />(AOC), and variances from contemporaneous reclamation, respectively, be reviewed by the Division. <br /> <br />Rule 3.02.2(4) requires that the Division review the amount of performance bond liability and the terms of <br />acceptance of the bond every 2½ years. <br /> <br />This Midterm Review consisted of a detailed review of the Keenesburg Strip Mine permit application <br />package (PAP) and previous Division findings of compliance to ensure that the proposed operation is in <br />compliance with the Rules and Act. The Division also reviewed all subsequent revisions and stipulation <br />responses to ensure that all permit commitments and conditions were being followed. Potential issues and <br />observations from past Division inspection reports were also considered. <br /> <br />The document has seven sections: <br /> <br /> Section I contains a brief description of the mine history and the surrounding environment. <br /> Section II contains a summary of permit actions since the last Permit Renewal. <br /> Section III is a summary of the Division’s review of the active stipulations attached to the permit. <br /> Section IV is a summary of the review of any previously approved experimental practices, <br />mountaintop removal variances, variances from approximate original contour (AOC), and variances <br />from contemporaneous reclamation. <br /> Section V summarizes any enforcement actions issued since the permit was last renewed, and the <br />current status of any actions that were issued. <br /> Section VI is a summary of the review and a discussion of any potential issues identified as a <br />result of this review that are required to be resolved. <br /> Section VII is a summary of the review of the reclamation cost estimate and the performance <br />bond(s) held by the Division. <br />
