3. Mine Facilities and Operation <br /> It is extremely unlikely that any toxic or acid-producing materials will be encountered during the <br /> mining operation as the site was historically rangeland. However, in the event that such <br /> materials are encountered,they will be covered with subsoil and topsoil from onsite stockpiles to <br /> the same depths outlined in the reclamation plan and no more mining will occur in the area.No <br /> blasting or explosives will occur/be used during mining nor on site. <br /> Fuel will be brought to the site by a mobile fueling truck and will be housed in the tanks detailed <br /> below.No permanent structures will be built within the permit area as part of this operation. <br /> Water will be used to control dust on the excavation and disturbed areas of the site. Water for <br /> this operation will be trucked to the site and purchased from an offsite source. It is estimated that <br /> the operation will consume 8,000 gallons of water per day for dust suppression. Portable plants <br /> will be used onsite for rock crushing and asphalt production. Spray bars will be used in the <br /> crushing and screening plant to further minimize dust. <br /> Aggregate processing equipment is portable and the processing area may move and follow active <br /> mining throughout the site; however, the processing area will likely remain in the southwest <br /> corner of the site. Portable mining equipment such as loaders,dozers,trucks and excavators will <br /> be serviced on an as-needed basis onsite. Upon reclamation, all portable equipment will be <br /> removed from the site. A summary of equipment and related tanks that may exist on site at any <br /> given time is listed below. <br /> - A portable asphalt plant with associated tanks <br /> - Truck scales <br /> - Equipment parking and maintenance <br /> - Overflow resource stockpiling <br /> - A portable crusher with associated tanks <br /> - Active pit serving as a stormwater settling pond <br /> - 250 gallon diesel fuel tank in secondary containment(110%of tank capacity) <br /> - 1,000 gallon water tank used for dust suppression <br /> - Portable lights with a generator for emergency after hours maintenance support <br />
