The two mine portals were backfilled in accordance with Volume 6A - Final <br />Abandonment Tab, Figure 2.05-6. <br /> <br />2. As the result of a mine fire in 1986, the ventilation shaft was sealed. <br /> <br />3. Although the mine permit describes "rock tunnels", they were never <br />constructed and therefore references to these structures and their <br />subsequent reclamation elsewhere in the permit should be ignored. <br /> <br />4. The East Mine was backfilled, graded and revegetated in accordance with <br />the approved plan during 2008 and 2009. <br /> <br />Timber Storage Area <br /> <br />The ROM storage pile was reduced from approximately 38,000 cubic yards of <br />stored ROM coal to approximately 17,000 cubic yards of ROM coal storage. To <br />dispose of the remaining ROM coal, the bench located immediately north of the <br />West Ridge coal mine waste disposal area was excavated below the level of <br />the coal mine waste. The remaining ROM coal stored at the timber storage area <br />was placed in this location during the fourth quarter of 2007 and first quarter of <br />2008. <br /> <br />The Timber Storage area was backfilled, graded and revegetated in <br />accordance with the approved plan during 2008. <br />
