- The highwall in the Marr Pit azea has been completely backfilled (using all <br />reasonably available spoil in the permit area) (Rule 4.14.1(2)(f)(i)). <br />- The Marr Pit Area has been backfilled in such a way as to be compatible with the <br />approved post-mining land use of rangeland and wildlife habitat and proper <br />drainage has been reestablished (see drainage control below). <br />(Rule 4.14.1(2)(f)(ii)). <br />- The highwall in the Marr Pit area has been completely backfilled so Rule <br />4.14.1(2)(f)(iii) does not apply. <br />- All exposed coal seams have been covered and there were no toxic or acid <br />forming materials identified at the site (Rule 4.14.1(2)(f)(iv)). <br />- The Marr Pit azea was continuously mined/reclaimed after 3 August 1977 so Rule <br />4.14.1(2)(g) does not apply. <br />- Based on the pre-mining and post-mining topography maps and the site <br />inspection, the final graded slopes approximate the pre-mining slopes (Rule <br />4.14.2(1)). <br />- No terraces were constructed in the Marr Pit area so Rule 4.14.2(2) does not <br />apply. <br />- All debris has been removed or buried (Rule 4.14.3(1)(a)). <br />- The overburden in Marr Pit area is not considered thin overburden so Rule 4.14.4 <br />does not apply. <br />- There is a small azea on the West Side of the Marr Pit that has sustained some <br />wind erosion damage (minor gullying). This azea has been worked on and <br />appears to be stable at the present time. The operator will need to revegetate this <br />azea but that is not within the scope of this bond release or inspection. (Rule <br />4.14.6) <br />Drainage Control -The drainage control at the Marr Pit consists of a series of ditches, <br />culverts and ponds, as well as the reestablished natural drainage channels. The ditches <br />ran along the remaining, permanent access road. The ditches were all clear, well <br />vegetated and appeared to be functioning properly. These ditches, along with the natural <br />drainage channels, divert all mnoff into either pond D or pond E. Ponds D and E were <br />constructed at the onset of mining and are properly constructed and sized to contain/treat <br />the runoff from a 10-yeaz/24-hour event. There are two spots where the runoff flows <br />through culverts (under the permanent access road). The first culverts are about 100 <br />yards below the entrance gates. There are two-24" culverts. The runoff from these <br />culverts goes to pond E. These culverts were clear and appeared to be functioning <br />properly. The second culverts are about 200 yazds below the first two culverts. There is <br />one-36" culvert and one-12" culvert. The runoff from these culverts goes to pond D. <br />These culverts were also clear and appeared to be functioning properly. <br />Summary and Conclusion -Based upon a review of the mine permit and approved <br />reclamation plan, the bond release application and the site inspection, the Division finds <br />that KCC has successfully completed backfilling, grading and drainage <br />control/reestablishment for the Marr Pit area. <br />Matr Mine SL-03 4 28 January, 2002 <br />
