Add that Kathy Welt assisted with the records review portion and Robin with the field inspection <br />portion, <br />2. Correct that the potential future PR will be to add about 2,200 acres of new leased fed'I acres (1,700 <br />ac) and MCC's private lands to the south, and <br />3. Most - importantly, the statement underlined below is not correct. Mike clarified to me that the coal <br />refuse will be hauled to and end - dumped into the hole (because it would be too steep for trucks to get <br />in and out of there), but once the refuse is dumped in the hole, it will be spread -out in 24" lifts and <br />compacted to the required standard. <br />"The operator plans to either end dump the refuse into the hole, dump the refuse beside the hole and push it in with a <br />dozer or some combination of the two methods. While there will be little to no mechanical compacting of this refuse <br />material (due to the steepness of the slopes to get into this area), this is the same method that is used for permanent spoil <br />fills and should not cause any stability problems." <br />Thanks for your consideration of these changes. <br />Cathy `Weft, <br />Environmental Engineer III <br />Mountain Coal Company, LLC <br />West Elk Mine <br />P.O.
