The table also shows that mining will occur over approximately 38.8 years. <br />3. Mine ]Facilities and Operation <br />• Since the post mining land use for the LaSalle Pit is an industrial yard, there will be a number of <br />industrial maintenance and storage facilities on site. Included among these are back hoes, dozers, <br />loaders, haul trucks, and other equipment used by the Montrose County Road and Bridge <br />Department. Parking and office facilities for Montrose County Road and Bridge employees will <br />also be constructed on site. Upon the completion of Phase 1, the main maintenance and office <br />facilities will be constructed on the pit bottom. <br />An asphalt plant will be present on site. Waste asphalt from this plant will be removed from the <br />site weekly. Asphalt spillage and reject will be collected weekly. The reject and spillage will be <br />placed in a single enclosure designed for waste asphalt. The waste asphalt will be hauled off site <br />to a permitted site for such material on an as needed basis. A single location for asphalt waste <br />storage will be used and will not be spread across the permitted site. <br />Water will be used to control dust on the haul roads and also on the crushing and screening <br />operations. Magnesium chloride may also be used as needed to control dust. Since mining will <br />• not take place below the water table, no pit pump will be necessary. <br />LaSalle Pit, April 09 D-4 <br />r.
