Midterm Review Carbon Junction Mine This document presents the results of the Midterm Review of Oakridge Energy's Carbon Junction Mine, conducted by the Colorado Division of Minerals and Geology (the Division). This Midterm Review was conducted to fulfill the requirements of the Colorado Surface Coal Mining Reclamation Act, and Rules 2.08.3, 2.06.2(9), 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 Reclamation Board for Coal Mining, promulgated to implement the Act. Rule 2.08.3 requires that the Division conduct a review of each permit issued, prior to its midterm (2'/z years). Based on this review, for good cause shown, the Division may require reasonable revisions to, or modifications of, the permit provisions to ensure compliance with the Act and Regulations. Rules 2.06.2, 2.06.3, 2.06.5, and 2.06.7 require that during the midterm review, where applicable, experimental practices, mountaintop removal variances, variances from approximate original contour (AOC), and variances from contemporaneous reclamation, respectively, be reviewed by the Division. The Carbon Junction Mine does not conduct experimental practices, nor have variances been granted for mountaintop removal or approximate original contour. Rule 3.02.2(4) requires that the Division review the amount of performance bond liability and the terms of acceptance of the bond every 2~/z years. This midterm review consisted of a detailed review of the Carbon Junction Mine permit application and previous Division findings of compliance to identify any items that may have been overlooked during the initial review. The Division also reviewed all subsequent revisions and responses to ensure that all permit commitments and conditions were being followed. Hydrologic monitoring data was reviewed in conjunction with the review of the application to assess the adequacy of the monitoring plan and discussion of predicted hydrologic impacts. Problems and observations from past Division inspection reports were also considered. Section I -History The Cazbon Junction Mine (C-82-054) was previously operated by Pueblo Coal, Incorporated, from its original permit date of October 25, 1983 until the company became insolvent when the permit was revoked and the bond forfeit on July 25, 1990. Due to the failure and closing of the Texas American Bank/Forth Worth, Texas, the Division was unable to collect the bond money to perform reclamation activities at the mine site.
