3. Mine Facilities and Operation <br />The crushing and screening will take place within the Mining Area 1. Fuel will be brought to the <br />site by a mobile fueling truck. On site fuel storage needs will vary depending on the plants that <br />are located on site at any one time. The mining, crushing and screening equipment will require a <br />single 3,000 gallon diesel tank which will be located near the crushing/screening plant as shown <br />on map C -2A. A 10,000 gallon tank will be located in the shop /office area as shown on Map C- <br />2A. Both tanks will have secondary containment of at least 110% of the full tank capacity. An <br />SPCC Plan will be placed in the mine office and the employees will be trained to take the <br />appropriate steps for inspections and spill response in case of a spill. All portable plants will <br />have their own tanks built into the plant that have built -in secondary containment and are <br />covered under their own portable plant SPCC Plans. If any fuel spill is encountered, the material <br />will be removed from the site. The Division will be notified in the case of any spill. Upon final <br />reclamation, all equipment will be removed from the site. <br />A portable wash plant will be utilized on site to create washed products for the Concrete and <br />Asphalt plants as well as sell washed aggregate products. The wash plant will be fed with <br />crushed and screened products and will remove the fine material as required in the material <br />specifications. These fines will be deposited in the wash pond located near the wash plant within <br />Mining Area 1. This pond will periodically be cleaned out. The fines will be deposited in the <br />depression around the plant area and reclaimed at the end of mining. Water consumed in the <br />wash plant will be hauled from the irrigation ditches on this parcel. See Exhibit G for additional <br />details on water use. <br />The portable concrete plant will consist of a time silo, fly ash silo, loading hoper, control room <br />and a batching hopper. Concrete mixer trucks will haul the material from the mining area to the <br />various project locations. The mixer trucks will be stored next to the concrete plant when not in <br />use. The sediment ponds will also serve as a concrete washout ponds. Excess concrete created <br />during batch operations will be laid out on a gravel pad and allowed to cure. The excess concrete <br />will be recycled in the crushing operation. <br />Uncompahgre Pit, February 2013 D -4 <br />
