Mining will be conducted from the southeast end of the site northwards and westwards. Due to <br /> the deposit size, 15-20 years of mining are possible. The initial mining cut will be roughly 26 <br /> acres in size. Mining will continue from this initial cut,that will be in the southeast end of the <br /> gravel terrace, northerly and westerly towards Empire and the West Fork of Clear Creek. The <br /> resultant mine pit will have overall side slopes of 3H:1 V. Mining down into the deposit before <br /> mining laterally will serve to obscure mining activities and their impacts from the surrounding <br /> community. The active highwall may be steeper when actively being excavated. <br /> Mining will be conducted using a combination of dozers, front end loaders, back hoes, and haul <br /> trucks. Topsoil will be stripped in advance of mining and placed in a windrow ahead of the <br /> mining area. Then, raw sand and gravel will be excavated, transported to a crusher and screen, <br /> and then processed into products for sale offsite. A portion of the crushed rock will be washed <br /> for further use in some products. Reject material from processing that is not sold will be used in <br /> reclamation. It is the experience of the applicant that fines salvaged from processing can improve <br /> the soil profile during reclamation. <br /> Once mining in an area reaches full depth, reclamation of the mined out portions of the slope will <br /> begin. The crest of each cut will be knocked down with a dozer to create the final 31-1:1 V <br /> reclamation slope. Following mining and reclamation of the initial cut, onward reclamation will <br /> be conducted concurrent with mining. This will reduce material moving as well as reduce the <br /> maximum area to be reclaimed. A timetable for the mining operation can be seen in Table D-1. <br /> Processing fines, overburden (if encountered) and imported fill may be used as backfill on <br /> slopes. Backfill placed on slopes will be to create even shallower conditions than 3H:1 V. <br /> Imported fill material that is used as backfill will comply with Rule 3.1.5(9). <br /> Mining activities are expected to occur approximately 9 to 12 months per year as weather <br /> permits. Processing operations including screening/crushing and washing can occur any time of <br /> the year. Sales of product material is expected to occur throughout the year. <br /> Expected annual average production is 1 million tons; actual production rates will fluctuate <br /> based on market conditions. Raw material will be sold as various products: crushed rock, chips, <br /> road base, concrete, and asphalt. A breakdown of the anticipated product tonnages and mined <br /> tonnages can be seen in Table D-1.
