MT8 2.05-28 Revised 02/28/22 <br />following vegetation establishment. <br /> <br />The regraded surface will be left in a roughened condition to minimize slippage and promote root growth and moisture <br />infiltration. The postmining topography of the area is shown on the Reclamation Plan Map (Map 29). Suitable plant <br />growth media will be redistributed over the regraded area, and the reclaimed area will then be planted with a cover crop, <br />and subsequently drill seeded with the rangeland/wildlife habitat seed mixture. If it is necessary to apply the seed by <br />the broadcast method, the seeding rate will be doubled. <br /> <br />The sediment ponds and associated drainage structures will remain in-place until final release, and will either be <br />permitted as a permanent livestock pond or be removed. If needed, soil materials salvaged from the pond areas will <br />be used to reclaim the ponds. The ponds will be graded to blend into the natural topography and seeded with the <br />rangeland/wildlife habitat seed mixture. <br /> <br />Coal Storage/Loading Silo <br /> <br />The coal silo has been demolished and the tracts have been removed. Given the close proximity to the Williams Fork <br />River, special measures were implemented to protect the river. Measures to protect the nearby Williams Fork River <br />during demolition included temporary placement of a protective barrier between the silo and river, and controlled <br />demolition to direct demolition debris away from the river. It should be noted that the main channel of the river is <br />separated from the silo area by both a substantial river bar and a small side channel. <br /> <br />Controlled demolition practice (explosive) was used to bring down and demolish the silo structure. There is a large <br />open area to the west-northwest of the silo which allowed demolition debris to be directed away from the river. Given <br />the importance of protecting the river, MCM selected and worked with a qualified and experienced demolition <br />contractor to develop specific plans for the silo demolition. The resulting concrete and other debris from the silo <br />demolition were placed at the toe of the face-up highwall at the portal area prior to backfilling. Once demolition of the <br />silo and removal of the resulting debris was completed, the associated surface disturbance area was reclaimed as part of <br />the No. 5 Portal area reclamation, as previously described. <br /> <br />Overland Conveyor <br /> <br />All of the overland conveyor systems and facilities were dismantled or demolished, including supports and footings. <br />The removal of the conveyor segments which cross over State Highway 13 and the Williams Fork River required special <br />measures, including coordination with the Colorado Department of Transportation, temporary closure of the highway <br />during conveyor removal operations, and the use of one or more high-lift cranes to remove, lift, and transfer the <br />individual conveyor segments to trucks for removal from the site. This was completed in the spring of 2017. All material <br />capable of being salvaged was salvaged. Any unsalvageable inert materials was placed at the toe of the face-up highwall <br />at the portal area prior to backfilling and/or placed in the 5A underground workings near the portal entries. Similar to <br />other pre-law disturbance areas, topsoil salvage was limited, so the upper weathered overburden material will be <br />recovered prior to backfilling and used as suitable plant growth media in reclaiming the site. <br /> <br />The affected areas will be backfilled and graded using adjacent spoil materials from the previous surface mining <br />operations and material from conveyor and stockpile pads. The backfilling and grading operations will leave the <br />regraded surface in a roughed condition to minimize slippage and promote root growth and moisture infiltration. <br />Contour ditches or furrows will be constructed on reclaimed slopes to reduce erosion and provide for effective drainage. <br />These ditches or furrows will be approximately 20 to 50 feet apart and have check-dams placed at periodic
