2.05.3 <br />The type of surface coal mining activities located within the 100 foot right-of- <br />way should not affect the two adjacent landowners or the public. Sediment <br />ponds and topsoil stockpiles should not be a problem to the adjacent <br />landowners or the public. The haul roads within the 100 foot right-of-way will <br />be gravel surfaced or paved and watered and cleaned as necessary to <br />control fugitive dust emissions to protect the interests of adjacent landowners <br />and the public. <br />Coal spillage from haul trucks is most often caused from overloaded or <br />uneven loading. Spillage from trucks will be promptly cleaned. <br />(vi) No stream fords are proposed for use as temporary construction routes. <br />(vii) The plans and drawings for the access roads and haul roads were prepared <br />under the direction of a professional engineer(s). <br />(4) Ponds, Impoundments and Diversions <br />(a) There will be four sediment ponds constructed for the mine facilities. The <br />ponds are named sediment ponds B, C, D and F. Sediment pond D will also <br />be referred to as the refuse pile sediment pond. The loadout will have two <br />sediment ponds. The ponds are named sediment ponds J and K. <br />Sediment pond A was deleted from the design. <br />Sediment pond B was relocated below (south of) old State Highway 133 <br />during the construction of the downhill conveyor and highway coal stockpile. <br />It is designed to handle the run-off from B -Gulch. Pond B will be a typical <br />sediment pond, capable of containing the run-off from a 10 -year event with a <br />spillway system designed to handle the peak flow generated by the 25 -year <br />storm event. Dewatering will be through the primary spillway or an optional <br />centrifugal pump. <br />Sediment pond C is located above (north of) the old Bowie railroad grade and <br />is designed to handle the run-off from C -Gulch. Sediment pond C also <br />receives inflow from the mine. A small water treatment building located <br />northwest of Pond C is used to add CDPS approved chemicals to the water <br />as necessary to clarify the water. A sediment pond is to provide adequate <br />capacity to contain or treat the run-off or inflow entering the pond as a result <br />of a 10 -year, 24-hour precipitation event and any additional storage resulting <br />MR -168 2.05-37- 11/14 <br />
