Mining Methods <br />The deposit will be dry mined, and a clay liner will be constructed around the perimeter of the <br />mining area. Design specifications for the clay liner and quality control procedures used during <br />construction will ensure that the reservoir meets State Engineer's Office (SEO) performance <br />standards. Dewatering trenches will be excavated around the entire perimeter of the disturbed <br />mining area. <br />The equipment and facilities may include, but are not limited to the following: <br />Processing Equipment <br />Screen, crusher, log washer, sand screw, conveyors, and other miscellaneous processing <br />equipment. <br />Earth Moving Equipment <br />Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth <br />moving operations. <br />Miscellaneous <br />An employee/storage trailer, scale house, and scale, will be located on-site. Dewatering <br />pumps and generators and watering trucks will be used as needed. <br />As mining progresses, topsoil and overburden will be stripped with excavators and haul trucks to <br />expose the aggregate product below. All soil and overburden material will be used on-site for <br />reclamation; so long-term stockpiling of these materials is not anticipated. Overburden <br />stockpiles will be located within the proposed mining cells and placed so that they do not impede <br />potential floodwaters. <br />Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will <br />occur concurrently with mining, it is not anticipated that bedrock material will be stockpiled <br />long-term prior to use. <br />The active mining face will extend no more than 1,200 ft in length. During mining and prior to <br />reclamation, the mining face will be a nearly vertical to %H: l V slope. The aggregate material <br />will be temporarily stockpiled near the processing plant. <br />Fines produced by the onsite processing facilities will be temporarily stored in settling ponds <br />located on the southeast end of the site. The fines will be allowed to settle from the wash water <br />and then allowed to partially dry to facilitate removal from the temporary settling ponds. The <br />fines will then be mixed with overburden material and placed in areas of designated backfill or <br />into the reclaimed section. <br />SerFer Project <br />DBMS 112 Permit <br />Page 6 <br />
