• <br />The mining schedule was developed to minimize disturbance by reclaiming mined out areas <br />while additional mining occurs. This schedule is based on a reasonable projection of average <br />production rates. It shows that mining will occur over approximately 9 years and the total gravel <br />mined will be approximately 412,000 tons. This is based on computer grids generated from the <br />topography and the available exploration data. <br />3. Mine Facilities and Operation <br />An asphalt plant may be located onsite, above the 100 year flood plain and the existing ground <br />water level. If an asphalt plant is brought to the site, it will be present only temporarily during the <br />summer months when paving projects are in progress. The crushing and screening will follow <br />the mining progression. The mobile plants will have attached fuel tanks which will also fuel the <br />mining equipment while the plants are present. All other times, fuel will most likely be brought <br />to the site by a mobile fueling truck. The only permanent structures that will be built for the <br />mining operation is the truck scale. Water will be used to control dust on the haul roads and the <br />crushing and screening operations. Water for this operation will be trucked to the site from an <br />offsite source. It is estimated that the operation will consume 4,000 gallons per day in dust <br />suppression for both sources. <br />Maintenance vehicles will visit the site regularly to provide oil, grease, and perform other minor <br />maintenance on vehicles and equipment. Any major repair work required will be performed off <br />site. <br />The following list is the best estimate of the required equipment to be used onsite throughout the <br />mine life: <br />Gravel Crushing Equipment <br />• Jaw Crusher <br />• Cone Crusher <br />• Screen Decks <br />• Stacking / Transporting Conveyors <br />• <br />Pinion Ridge Pit, June 2008 C-3
