A set of dozers and loaders will be used to excavate the raw gravel and feed it to a conveyor system <br />and/or haul trucks which will transport it to the crusher /screener. <br />The mine hours of operation are as follows: <br />• Extraction and reclamation: 7:30 a.m. to 7:00 p.m., Monday through Friday. No extraction and <br />reclamation on Saturdays <br />• Crushing and Processing of material: 8:00 a.m. to 6:00 p.m., Monday through Friday. No <br />crushing or processing on Saturdays <br />• Loading and hauling of material from August 15 through May 31: 10:00 a.m. to 6:00 p.m., <br />Monday through Friday; 10:00 a.m. to 2:00 p.m. on Saturdays <br />• Loading and hauling of material from June 1 through August 14 8:30 a.m. to 6:00 p.m., <br />Monday through Friday; 9:00 a.m. to 2:00 p.m. on Saturdays <br />• No extraction, hauling, or operation of trucks or other equipment shall occur on Sundays and <br />national holidays, which are Christmas Day, Thanksgiving Day, New Year's Day, Fourth of <br />July, Presidents' Day, Memorial Day, and Labor Day. <br />• Warming of equipment will take place starting 15 minutes prior to startup. <br />No mining will take place at night. <br />No fuel storage will be on site with the exception of the tanks attached to the crusher /screener. All <br />mobile equipment will be serviced by a mobile fuel truck that will come in from off site. The Crusher <br />and Screen Plant will have a total of 6 separate tanks for diesel fuel, two each at 250 gallons, two each <br />at 500 gallons and one at 600 gallons. This portable plant has separate fuel tanks for each component <br />of the plant: primary crusher with two saddle tanks, two cone crushers and two screens. <br />The following list is the best estimate as to the mobile equipment which will be used onsite throughout <br />the mine life: <br />• 2 front -end loaders <br />• 1 dozer <br />• 2 excavators <br />• 3 haul trucks <br />Steamboat Sand and Gravel Pit, April 2012 D -5 <br />
