<br />Lonq Term Ash Disposal Plan <br />The applicant is backfilling utility plant waste materials into mine pits. <br />This material comes from the adjacent Craig Power Plant and consists of fly <br />ash, bottom ash, and scrubber sludge. <br />Approximately 60% of the utility waste will be fly ash, 20% will be bottom <br />ash, and 20% will be scrubber sludge. A maximum of 5,?.50 tons per day of the <br />waste will be disposed of the Trapper Mine with an average of 1,222 tons/day <br />expected. This is equivalent to an average annual volume of waste of about <br />231 acre-feet, after compaction. The applicant estimates that this waste <br />burial process will continue for the life of the mine. <br />Reclamation Plan <br />After final grading of the spoil, topsoil is placed on the spoil to a depth <br />commensurance with the post-mining land use. Areas are then seeded. <br />Reclamation efforts are monitored to insure success of revegetation of the <br />reclaimed areas. <br />Reclamation, in terms of backfilling and grading, will not be contemporaneous <br />within the context of the time limits of the Rules and Regulations, due to the <br />pit lengths, the need to renove interburden from above recoverable coal seams, <br />and cycling times. The operator has committed to the criteria that there will <br />never be more than four unregraded spoil rows (including the active one) at <br />any one time. This has been approved as a variance by the Division and is <br />bonded accordingly. <br />-10- <br />
