a discharge permit from the Colorado Department of Public Health and <br />Environment (CDPHE) and permission from the ditch company prior to release <br />of any discharge from the site. The applicant will comply with all CDPHE <br />regulations including monitoring and reporting requirements for the life of the <br />mine. <br />After the Phase 1 area is dewatered, scrapers will strip the topsoil and create the <br />berms or stockpile it. Next they will strip the overburden and use it to raise the <br />processing azea above the 100-year floodplain elevation. Any remaining <br />overburden will be stockpiled and ultimately be used in reclaiming and sloping <br />the shore or sold. When the alluvium is sufficiently dry, an excavator will place <br />the gravel in haul trucks or on conveyors to transport the material to the <br />processing area. As the area is mined, overburden will be placed along the <br />edges to create the shoreline of the future reservoir. Topsoil will be placed on <br />finished slopes above the high waterline and the area will be seeded. After the <br />mining has been completed, the dewatering trench will be extended to include <br />the next section to be mined and the process will begin again. <br />Equipment <br />The following is a list of equipment to be used at the site: <br />Loaders (4) Generators (2) <br />Feeders (3) Haul Trucks (4) <br />Screens (2) Exoavator(1) <br />Scale (1) Fuel Tank (1) <br />Crushers (2) Fuel Truck (1) <br />Dozer (I) Conveyors (4) <br />Scraper (1) Road Grader (1) <br />Mechanic Truck (1) Ready Mix Conc Tracks (25) <br />Staking Conveyor (3) Electric Control Van (1) <br />6hop Building (1) <br />Office Trailer (1) <br />Recycle Plant (1) <br />Portable Toilets (3) <br />Water Truck (1) <br />Imported Material <br />Asphalt Batch Plant (1) <br />Concrete Batch Plant (1) <br />Aggregate Wash Plant (1) <br />Blending Plant (1) <br />Hall-Irwin may import materials for processing, batch or blending plants and for <br />sale at the landscape yard. <br />b. Earthmoving: sand and gravel will be excavated and loaded into haul trucks, or <br />onto conveyors which will transport the material to the processing area. <br />c. All water diversions and impoundments: the perimeter of the pond will be <br />dewatered by digging a trench approximately 37-46 feet deep to <br />claystone/siltstone material. For the initial phase the water will be pumped into <br />Hall-Irwin Corporation Page 15 of 35 <br />MLRB 112 Permit Application <br />
