<br /> <br /> <br /> <br />PR-04, Colowyo Coal Mine C1981-019 51 August 2016 <br /> <br />XI. Contemporaneous Reclamation - Rule 4.13 <br /> <br />The Permit is found to be in compliance with Rule 4.13. Reclamation was found to occur as <br />contemporaneously as practicable with mining operations. Based on the nature of mining in the <br />Collom Pit, which will be a multi-seam operation, backfilling and grading cannot be completed <br />within 180 days of the removal of the uppermost coal seam. In addition, the number of spoil <br />ridges may exceed four at multi-seam operations. Finally, variances from contemporaneous <br />reclamation may be necessary to accommodate high-wall mining operations. <br /> <br />The Division has granted Colowyo a variance for contemporaneous reclamation for the Collom <br />Pit. Additionally, given the constraints of the pit, the number of coal seams and sub-seams being <br />mined and the topography, very little reclamation will be completed in the current permit term <br />(ending November 5, 2017). <br /> <br /> <br />XII. Backfilling and Grading - Rule 4.14 <br /> <br />The Permit was found to be in compliance with Rule 4.14. <br /> <br />A. Operations and Reclamation Plans <br /> <br />Colowyo's mining operations plan is found in Section 2.05.3 of the PAP, and the reclamation <br />plan is in Section 2.05.4. Section 4.14 contains the performance standards for backfilling and <br />grading. <br /> <br /> <br />B. Contemporaneous Reclamation <br /> <br />Section 4.13 of the Permit contains information on contemporaneous reclamation for Colowyo's <br />multi-seam operations, with additional information found in Sections 2.05.4 and 4.14. As noted <br />above, the Division has granted Colowyo a variance for contemporaneous reclamation for its <br />operations, including the Collom Pit. <br /> <br /> <br />C. Approximate Original Contour <br /> <br />With PR-04 CCC has proposed post-mining topography for the Collom area that is significantly <br />higher than pre-mining topography. The Division has accepted this plan because it is in <br />compliance with Rules 2.05.3, 2.05.4, and 4.14.2 regarding AOC. Per the reclamation plan for <br />Collom, drainages will be constructed with gradients similar to those originally present, and
