The Division has determined selected overburden materials shall be used for, or as <br />a supplement to, topsoil. This variance applies to areas at the 5A Portal, old shop, <br />and temporary office area due to their disturbance prior to the Act and the lack of <br />salvaged topsoil at these locations. This determination is based on physical and <br />chemical analyses and field trials approved by the Division. Previously, <br />Stipulation No. 2 had been attached to the permit. This stipulation was complied <br />with upon the submission of Technical Revision No. 8. Details of the overburden <br />analysis may be found in Exhibit 41 (4.06.2(4)(a)). <br />IV.

Drill hole sealing <br />may be found on in Section 2.05 of the permit. All existing and future drill holes will be <br />sealed in accordance with Rule 4.07. Mine No. 9 portals were sealed prior to waste <br />material being placed at the No. 9 Mine Portal Excavation. Inspection reports indicate <br />that sealing and initial material storage in the No. 9 Mine Portal Excavation commenced <br />prior to 1991. The Mine No. 5 portals were sealed in 1997 in accordance with Rule <br />4.07.3. Final backfill of the portals and highwall above the portals has not been <br />completed at the time of this permit renewal. Mine No. 5A portals were sealed in 2003 <br />in accordance with Rule 4.07.3. Backfill of the Mine No. 5A portals has not occurred at <br />the time of this writing. <br />V.
