Sage Creek area, scrapers will open a pit f the Sage Creek coal seam and place the overburden over <br />the rough graded Wolf Creek spoils to the outh. Once the Sage Creek seam is removed from the pit, • <br />the dragline will proceed to mine the deep r Wolf Creek seam. This sequence will continue until the <br />northern limit of the mining block is reache ,whereby final reclamation activities will commence. <br />The highwall miner is currently scheduled o begin operating at the Yoast Mine in the spring of 2004 <br />and then proceeds to II-W in late spring/ea y summer of 20D5. This scheduling depends on a number <br />of factors that rely on the actual operatin conditions encountered. The mine plan and schedule is <br />based on the highwall miner penetrating 60 feet into the coal seams. The timing for moving to other <br />blocks could change at any time depending n pit and coal seam conditions. For instance: <br />- if the average highwall miner pen tration distance is less or more than designed (600 feet <br />penetrationl, the timing will change accordingly; or, <br />- if the coal seam characteristics or it conditions encountered are different than predicted and <br />won't allow coal recovery or con ersely will allow additional coal recovery, the timing will <br />change accordingly. <br />It should be stressed that all mine progre Sion and sequencing dates (scheduling) are for estimation <br />purposes only. The original dragline planni g was developed to meet coal delivery contracts and could <br />fluctuate based on power plant demand, c al orders could increase or decrease on a monthly basis. <br />The introduction of the Highwall Miner to the operations adds another variable to the overall timing <br />presented on Exhibits 12-3, 12-3a, and 1 -3b. This current mine plan is based on meeting existing • <br />coal delivery contracts. <br />Potential changes to the overall timing coul~be significant and could change the overall timing Iby year) <br />of the projected mine plan and ultimately th final reclamation schedule. <br />All mining is expected to be completed b 2008 when reclamation of all facilities will commence, <br />unless a bonafide request is made by the la downer to retain certain facilities and the Division approves <br />such a request. Such a request has been ade for Sediment Pond #005, X006 (Tab 161, and a portion <br />of Haul Road G. SCC is also requesting t e Mine Entrance Road, Haul Road A, remaining portion of <br />Haul Road G, a portion of Haul Road K, and he Ridge Line Access road be retained after mining. Exhibit <br />20-2 shows the location of these postmini g facilities, please refer to Tabs 13, 19, and 25 for further <br />explanation. <br />Future Permit Areas <br />It is anticipated that a permit renewal a plication will be submitted each five years, prior to the <br />expiration date of the permit currently in for e. Those areas to be permitted for mining and reclamation <br />under subsequent five-year permits are iden ified by year on the Operations Plan and Reclamation Plan, • <br />Exhibits 12-2 and 12-3 and 19-1 and 19-1 This assumes that, for ease of identifying areas, 1990 is <br />not counted as a full year.
