Exhibit D — Mining Plan <br />This mining permit is for a gravel pit on 40.44 acres owned by Garnet Mesa Investments, LLC. <br />The property is situated about three miles east of the town of Delta, Colorado and 1/2 mile south <br />of the Gunnison River. The land is currently irrigated crop land and has been for many years. <br />Access is from Delta County 1800 Road onto a private farm road owned by the applicant. The <br />existing private roads that access the site and 1800 Road will be improved to handle truck traffic. <br />The private roads will remain in place for use of the land owner after mining and reclamation of <br />the site is complete. They are therefore not included in the permit area. <br />Mining will begin in the northeast quadrant of the property. The farm road used for access will <br />be improved to handle heavy vehicle traffic and a crossing over the concrete ditch onto the <br />property will be built. Topsoil and overburden will be stripped from the surface of <br />approximately 10 acres and stockpiled in separate piles. One topsoil stockpile will be used to <br />create a berm in the northeast corner to shield the Carver residence from the noise of the <br />operation. The berm will be approximately eight feet high, 48 feet wide and 300 feet long with <br />side slopes between 2.5:1 to 3:1 h:v. Another topsoil and/or overburden stockpile with similar <br />cross section will be built in the southeast corner of the property to shield Homestead Road from <br />visual and noise impacts. Topsoil stockpiles that are not to be disturbed for more than a year will <br />be broadcast with dry land pasture mix to prevent erosion. Excess overburden will be stockpiled <br />along the eastern boundary of the property so that it is out of the way of short term excavations. <br />A 50 foot buffer zone of un -mined land will be maintained along the perimeter of the pit to allow <br />for topsoil stockpiles and access for reclamation operations. Scrapers, front -end loaders and <br />possibly a dozer will be used for this work. Excavation of gravel will be done with excavators, <br />front -end loaders and possible a dozer. As material is removed, the operator will cut slopes to <br />the final 3.1 h:v slope required for final reclamation to 01 feet below the expected water surface <br />when the pond is allowed to fill at the end of mining. Slopes deeper than 10 feet below the water <br />surface may be cut to 2:1. This way reclamation is concurrent with mining and the only slope <br />reduction needed in a bond forfeiture situation are the internal high walls. <br />A settling pond approximately 25 feet by 100 feet by 2 feet deep will be built along the existing <br />tail water ditch on the north side of the property just west of the center of the permitted area. <br />This settling pond will receive discharge from the de- watering pump once ground water is <br />encountered.. When the pit is excavated to full depth in the northeast quadrant, the settling pond <br />and sump will be established in on the pit floor with the clear water discharged to the same tail <br />water ditch, which will carry it to the Gunnison River. <br />The initial stripping and stockpiling of topsoil and overburden and establishment of the road and <br />the initial settling pond is expected to be accomplished in the first month of operation. Initially, <br />about 10 acres will be stripped to allow room for crushing, screening and stockpiling as well as <br />mining operations. The operator intends to mine the east half of the property while keeping the <br />west half in irrigated crops until sales make it necessary to begin mining the west half. At that <br />time, mining will move west into the northwest quadrant and then south till the property is mined <br />out. The operator anticipates mining 75,000 to 100,000 tons of material per year for <br />approximately 20 years. Economic conditions may significantly alter quantities and time frame. <br />Warren Pit 2012 <br />
