X. Slides and Damage - Rule 4.12 <br />The Permit is found to be in compliance with Rule 4.12. Because of the mining technique used, <br />natural barriers are not necessary. Slides have occurred within the permit boundary; however, <br />none have had an adverse effect on public property, health, safety, or the environment. Slides <br />have been reclaimed as appropriate. <br />XL Contemporaneous Reclamation - Rule 4.13 <br />The Permit is in compliance with Rule 4.13. Reclamation occurs as contemporaneously as <br />practicable with mining operations, as further discussed in Section XII below. <br />XII. Backfilling and Grading - Rule 4.14 <br />The Permit is in compliance with Rule 4.14. <br />A. Operations and Reclamation Plans <br />Colowyo's operations plan is found in Section 2.05.3 of the PAP (Volume 1 for the East Pit, <br />West Pit, Section 16 Pit, Facilities Area and Gossard Loadout and Volume 12 for the South <br />Taylor Pit). Maps 23 and 23A contain the mine plan. Section 2.05.4 contains the reclamation <br />plan, and Section 4.14 contains the performance standards for backfilling and grading. <br />During the approval process of Permit Revision 02, the Division added Stipulation 2 regarding <br />the Lower Wilson mining area to the operations and reclamation plan at the Mine. <br />B. Contemporaneous Reclamation <br />Section 4.13 of the PAP contains information on contemporaneous reclamation for Colowyo's <br />multi -seam operations, with additional information found in Sections 2.05.4 and 4.14. <br />Backfilling and grading cannot begin with multi -seam operations until the lowest seams are <br />mined. Therefore, backfilling and grading cannot be completed within 180 days of the removal <br />of the uppermost coal seams. Also, the number of spoil ridges may exceed four at multi -seam <br />operations. In addition, variances from contemporaneous reclamation have been granted to <br />accommodate high -wall mining operations. <br />Reclamation activities in the East and West Pits will be ongoing during the current permit term. <br />The reclamation schedule for the East Pit and West Pit is shown on Map 29, Spoil Grading. <br />Proposed Decision and Findings of Compliance January 2012 <br />Permit Renewal 06 Page 145 <br />
