EXHIBIT C - Mining_Plan <br /> a) The mining is expected to begin as soon as possible after a permit is obtained. The <br /> operation will provide material for concrete production. Anticipated life of the pit is <br /> indefinite. <br /> b) Mining will begin close to the center of the property and move outward. Excavation <br /> will continue as the need for material continues and as the supply remains available. <br /> There is topsoil in the area that averages about 5" in depth. The pit will have the <br /> topsoil stripped and stockpiled for re-application during reclamation. Topsoil will be <br /> stripped and stockpiled to the east side of the area to be mined. Any topsoil stockpile will <br /> be seeded with grass to prevent wind erosion. There also appears to be 6" up to three <br /> feet of overburden. Overburden will be separately stockpiled to the east side of the <br /> pit and seeded to prevent wind erosion. <br /> c) There would appear to be no waste rock or material at the site. <br /> d) Mining is anticipated to a depth of around 20-30 feet. We anticipate that the pit will <br /> intercept groundwater due to proximity to the South Platte River. Assuming that the <br /> pit may ultimately be filled with water, all slopes under the water will be no greater <br /> than 2:1. Interception of surface drainage will not occur. No detrimental effects of <br /> quality are anticipated. <br /> e) The entire acreage owned by Platte Valley Real Estate. PVRE intends to subdivide <br /> the balance of the acreage and make it available for commercial use. Planned within <br /> the subdivision is a street (currently labeled in the draft drawing as Jack's lane). The <br /> pit will be accessed from existing Edith Avenue to newly created Jack's Lane. <br /> Chamberlain Concrete will operate the pit. They have purchased a parcel to the west <br /> along Edith Avenue. There will be no shop, plant, or other facilities located at the <br /> mine site. Those facilities will be offsite at the other parcel. The equipment that may <br /> be used to mine the gravel will be a front-end loader, dozer, and trucks. Some <br /> stockpiling of usable material may be done at the site, but most of the material will be <br /> utilized as it is mined. Any stockpiling that does occur will be placed in the <br /> immediate vicinity where mining is occurring. The anticipated stockpile area is <br /> shown on the mining plan. <br /> f) There is no existing disturbance at the site. <br /> g) No access roads will be built since they will be part of the newly developed <br /> subdivision. <br /> h) There will be no water used in conjunction with the mining operation. When water is <br /> encountered, a drayline will be used for excavation. <br /> i) Mining will occur within the groundwater at the site. <br /> j) PVRE does own a well on the property and will provide augmentation. <br />
